To all whom it may concern:

Be it known that we, EDWARD N. RowELL a and JAMES LITTLE, citizens of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented a new and useful Improvement in Paper-Box Machines, of which the following is a specification.

This invention relates to a machine for making paper boxes composed of a cylindrical body and a circular head which are i united by a band of gummed paper wound around the body and the head.

One object of our invention is to produce a machine in which the feeding of the heads and the winding of the'bands are effected automatically.

Another object of our invention is to provide simple means for turning the edges of the bands inwardly over the edges of the body in an expeditious manner.

of our improved box-making machine. 25

Likelctters of reference refer to like parts in the several figures.

A represents the stationary base or main frame of the machine, and B represents a horizontally -reciprocating slide or table which is guided in ways 0 0, arranged on the horizontal upper portion of the frame.

I) represents a gear-rack secured length- Wise to the under side ofthe reciprocating table, and D represents a stationary gearraek secured lengthwise to the lower portion of the main frame vertically in line with the table gear-rack D.

E represents a vertical gear-wheel which engages with the movable and stationary gear-racks and is journaled upon a-horizontal wrist-pin e.

F represents a counter-shaft journaled Fig. 31 is a horizontal section transversely in bearings on the lower portion of the main frame and provided centrally below the reciprocating table with a crank f. This crank is connected with the wristpin 0 by a connecting-bar f. Upon revolving the counter-shaft the gear-wheel E is rolled back and forth on the stationary gearrack by the connecting-bar and crank, which causes the movable gear-rack and the table connected therewith to be reciprocated forwardly and backwardly a distance equal to twice the throw of the crank in a wellknown manner.

F represents the main shaft journaled transversely in bearings arranged on the main frame and provided with a small gearwheel F which meshes with a large gearwheel F mounted on the rear end of the counter-shaft, whereby the latter is driven.

G represents a mandreLframe which carries the mandrels for supporting the cylin drical bodies of the boxes. I This mandrelframe is arranged above the reciprocating table and consists ofa hub g and two pairs of bearings g 9 arranged on diametrically opposite sides of the hub. The mandrelframe is provided at its front end with a transverse shaft 9*, which is journaled hori zontally in a bearing formed in the upper end of a standard g, secured upon the main frame.

H represents mandrels upon which the. cylindrical bodies H of the boxes are placed by the operator, as shown in Figs. 13 and 14. Each of these mandrels preferably consists of a circular head h, having an annular flange on its rear end and a split mandrelring h, surrounding the head and loosely connected therewith by rivets or bolts 7L2, secured to inwardly-projecting ears h on" the split ring and passing loosely through openings h, formed in the head. The peripheral front portion of the mandrel-head and the contiguous inner face of the mandrel-ring are tapered so that upon sliding the ring upon the head in one direction the ring will be spread, while upon sliding the ring in the opposite direction the ring will be contracted. In the normal position of the mandrel-ring it is arranged on the front portion of the mandrel-head and contracted suflicient to permit the circular body of the box to be easily placed upon the same. Upon moving the mandrel-ring backwardly onthe head the ring is spread, thereby gripping the body of the box and holding the same against turning on the mandrel. Each mandrelhead is secured to the rear end of a short horizontal shaft 715, which is journaled in a pair of the bearings of the mandrel-frame. Upon turning the mandrel-frame either of its mandrels can be brought into an operative or inoperative position over the reciprocating table.

The construction of the mandrels may be modified, as shown in Figs. 27 and 28. In these figures H represents the annular mandrelhead, and H holding-jaws arranged to slide in radial ways H, formed in the face of the mandrel-head andextending inwardly from the periphery thereof. The outer ends of these jaws are curved, so that when they are moved outwardly they close the outer ends of the ways and complete the peripheral face of the mandrel.

H represents a shifting cone arranged axially in a correspondingly-shaped opening formed in the mandrel-head and provlded at its rear end with a shank H, arranged to slide in a socket H formed in the mandrelhead. The shifting cone is normally held in a forward position by a spring H arranged in the socket H and bearing against the rear end of the shank.

I-I represents knuckles formed on the inner ends of the sliding jaws and engaging with undercut grooves H formed in the tapering sideof the shifting cone at an angle to the line of movement of the sliding jaws. In the normal forward position of the shifting cone the jaws are drawn inwardly, so that their outer ends recede from the periphery of the mandrel. Upon placing the body of the box upon the periphery of the mandrel it tends to flatten across the spaces at the outer ends of the ways H Upon pressing the cone into the mandrel-head the jaws are moved outwardly, so that their outer ends are flush with the periphery of the mandrelhead, thereby pressing out the flattened portions of the body and holding the same tightly upon the mandrel.

h represents gear-wheels secured to the mandrel-shafts between the bearings of the mandrel-frame and adapted to engage alternately with a gear-rack 7L secured lengthwise upon the reciprocating table in line with the said gearwheels. During the forward movement of the table the mandrel-frame is Y so turned that neither of the mandrel gearwheels is in engagement with the gearrack 727. When the reciprocating table has reached the limit of its forward movement, the mandrel-frame is turned so that one of its gear-wheels stands in the path of the gear rack M, which causes the latter during the subsequent backward movement of the table to engage with said gear-wheel and rotate the mandrel connected therewith. In order to insure the proper engagement of the mandrel gear-wheels with the mandrel gearrack, the latter is provided at its rear end with a yielding gear-section 7L8, which forms a rearward extension of the mandrel gear-rack and is yieldingly supported by a spring h", secured to the table. If'the relative position of the mandrel gear-wheel and the yielding gear-section is such that the latter will not mesh with said gear-wheel upon striking the same, the gear-secti on will be dei j iieotediuntil the gearwheel has' shifted sufliquarters, so that the other mandrelis brought J .ciently. to cause it to mesh properly with the gear-sectionwhen thelatterresumes its nory .mal position. yp i I represents jafiratchet-disk whereby the mandrel-frame is'intermittently rotated and whichissecured to the front end of the shaft supportingthe mandrel-frame;

represents an oscillating ratchetarm fro whereby the, ratchet-disk is turned and whioh isipreferablypivoted concentrically on La hub formed on the front end of the ratchetdisk. "The free end of the ratchet-arm is ,3 provided with a pawl t, which engages with i 5;;one of four notches it, formed equidistant in ,the periphery of the ratchetdisk. n l f i represents a .detentepawl pivoted with r y its lowerend on the main frame and engaging with itsfree hooked end in the notch follow- ,i zo ing the notch with which, the pawl of the ratchetearmwengages." The hook of the de. tent-pawlis yieldingly held in engagement with the notches, of theratchet-disk by a Spring it During the last portion of the 2 5 backward movement of the ratchet-arm the latter engages with a pin t on the detent pawl and forces the hook of the detent-pawl outof the notch, which permits the pawl of the ratchet-arm to enter the notch from j o which the detent-pawlhasjust been removed, and during the subsequent forward movement of the ratchet-arm the ratchet-disk is moved forwardja quarter-turn.

The heads are -intro duced into the rear portion of the magazine through an opening in the top thereof and are constantly pressed forward by. a follower .1- ing through therear end of the magazine, and movedforwardly by a weight 3' which is connected with the red by a cord 9", passing around a roller on the rear endof themaga K represents a vertically-sliding feed-plate which moves transversely across the front end of the magazine and successively delivers the heads through an opening is injthe topof the magazine. Every time the feedplate crosses the magazine its upper edge strikesthe lower edge of the foremost head and pushes the same upwardly through the discharge-opening.

. 76 is an oscillating elbow-lever whereby an intermittently-reciprocating movement is imparted to the feed-plate and which is pivoted to the main frame. The upper arm of the elbow-lever consists of arigid section k and a yielding section 16, pivoted to the rigid section. The yielding section is free to swing downwardly on the rigid section, but is limited in its upward movement thereon by a stop 76*, against which the yielding section is normally held by a spring k The yielding section of the elbow-lever is connectedwith the lower portion of the feed-plate by a link 7c. If from any cause the upward movement of the feed-plate should be ar-' rested-as, for instance, clogging of the The latter is provided with a rod j passhead-discharge opening-the yielding section of the elbow-lever permits the remain mg portion of said lever, which latter is .moved positively, to continue its move-.

ment independent of the yieldingsection, thereby preventing injury to the elbow-lever andconnecting. parts. The lower arm of the elbow-lever is provided with a pin 76 which engages in the peripheral groove of a camJc whereby the elbow-lever is actuated. This cam, is mounted on a cameshaft 7c, j ournaledlengthwise in bearingssecured to the lower rear portion of the mam frame.

L represents a carrying-arm whereby the arm. The jaws ofthegripper are provided in their inner or opposing faces with vertical grooves Z for the reception of the marginal portionof the heads. The gripper-jaws are IIO between them is less than the diameter of a head, by a spring 1 secured with one end to the movable jaw and bearing with its other end against the carryingarm. The fixed end of the carrying-arm is secured to the upper end of a vertical rock-spindle l, which passes through the top of the main frame in rear of the reciprocating table. This spindle is square in cross-section and is arranged in a corresp ondingly-shaped socket formed lengthwise in a rock-sleeve l, which compels the spindle to oscillate with the rock-sleeve,but permits the spindle to move lengthwise in the same. The rock-sleeve is journaled in an upright bearing Z, arranged on the main frame. The lower end of the rock-sleeve is provided with an arm P, which projects rearwardly through an opening in the main frame. Z is an elbow-lever pivoted on the rear side of the main frame and connected with its upper arm by a link Z to the arm of the rock-sleeve, while its lower arm is provided with a pin or roller which engages with a cam Z on the counter-shaft. is so formed that the carrying-arm is oscillated one-quarter of a revolution, whereby the gripper of the latter carries a head from the magazine to the face of the lower operative mandrel and then disengages itself from the head and returns to its former position over the magazine.

M represents a lifting elbow-lever whereby I the carrying-arm is raised as it passes back and forth between the magazine and mandrel and which is pivoted on the main frame. One arm of the lifting elbow-lever is provided with a fork m, which engages loosely with a groove-head 'm in the lower end of the spindle Z", while its other arm is provided with a pin or roller m which engages with a liftingcam m arranged on the cam-shaft. This cam is so formed that it raises the carryingarm as it oscillates between the magazine .and mandrels, thereby enabling the gripper and head to clear the upper parts of the machine. The carrying-arm is provided on its under side adjacent to the spindle with two V-shaped lugs m*, which are adapted to engage with one of two pairs of V-shaped notches formed in a cap m secured to the upper end of the upright bearing Z. These lugs and notches assist in centering the carrying-arm when it arrives in its proper position with reference to the magazine or the mandrel. In order to steady the gripper while it holds the box-head in front of the lower mandrel, the rigid arm of the gripper is provided with a guide-pin m which is adapted to engage alternately with two guide-hooks m arranged on opposite sides of the mandrel-frame, as shown in Figs. 8 and- 21.

N represents a holding-disk whereby the box-heads are held against the lower man- The cam Z body of the box. This holding-disk is pivoted centrally on the front end of a'transverse sliding rod n, which slides in a bracket n, arranged on the rear portion of the main frame.

n represents a rock-lever whereby the holding-disk is carried toward and from the lower mandrel and which is pivoted on the rear portion of the main frame. The rocklever is moved forwardly by a cam a on the cam-shaft bearing against the lower arm of said lever and is moved'in the opposite direction by a spring n, secured to the main frame and bearing against the up er arm of the rock-lever. The upper arm 0 the rocklever is provided with a slot M, Fig. 17, and is secured to the rear end of the sliding rod n by a pin n, passing through said slot.

n is a follower arranged in a socket formed in the rear end of the sliding rod n and pressed against the upper arm of the rock-lever n by a spring a arranged in said socket. During the forward movement of the rock-lever the holding-disk N moves with the same until it strikes the box-head on the mandrel, when the rock-lever,. during the remainder of its I forward movement, independent of the hold-' ing-disk, compresses the spring a This yielding connection'between the rock-lever and holding-disk permits of a slight variation in the thickness of the box-heads.

0 represents a band-supporting rail which is arranged lengthwise underneath and in line-with the periphery of the mandrels andupon which is laid the band of aper O to be wound around the body and tlie head of the box. The band-rail is secured to a carryingplate 0 which latter is secured to the top of the reciprocating table.

0 is a turning-rail arranged on the carrying-plate in rear of the band-supporting rail parallel therewith and separated therefrom by a longitudinal groove 0, in which the margin of the box-head runs when the mandrel revolves. i

0 represents a raised guide-rail arranged along the front side of the bandrail, and 0 is a similar rail arranged on the rear side of the turning-rail. The rails 0 and 0 guide the band of paper as it is delivered upon the sup porting-rail O and hold the same in place. As the mandrel carrying the body and head of the box rotates in contact with the band lying on the supporting and turning rails O 0 that portion of the band resting on the supporting-rail is wound around the body of the box and that portion extending across the groove 0 and resting on the turning-rail is turned over the margin of the head and against the under side of the latter, so as to connect-the body with the head. The rear guide-rail 0 overhangs the turning-rail, and the latter is adjusted with reference to the band-rail by screwso arranged in the rear guide-rail and bearing against the rear side of the turning-rail, as shown in Figs.l9 and ply-roller (not shown in the drawings) from which a sufficient length to encircle the box is unwound at every forward stroke of the reciprocating table by a gripper P, carried by the table and which seizes the end of the band, the portion of the band thus delivered upon the table being severed by a cutter,

hereinafter described, preparatory to being wound around the box. This gripper bears against a depressed gripper-face p, Fig. 6,

1 formed on top of the band-rail, and is provided with'a depending shank p, which passes vertically through recesses 10 p formed, in the band-rail and the carryingplate, respectively.

p is a rock-shaft whereby the gripper is opened and closed and which is journaled transversely in the carrying-plate and extends from its rear side into the recess p thereof. The inner end of the rock-shaft p is provided within the recess p with a rock-finger p, which is arranged with its free end in a socket 2), formed in the shank of the gripper. i The gripper rock-shaft is provided at its rear. end with a trip-arm q, as shown in Figs. 2 and 7 whereby the gripper is opened and closed. The gripper is yieldingly held in a closed position by a spring g, secured to the reciproeating table and bearing against a pin g on the trip-arm. The free end of the trip-arm is provided with a lug adapted to engage with primary and secondary trip-cams 9, whereby the gripper is opened for receiving and releasing the band of paper. The primary trip-cam Q3 inclines from its front end upwardly to its rear end and is pivoted at its upperrear end to a bracket g arranged on the main frame. Duringthelast portion of the backward movement of the reciprocating table the trip-arm rides over the incline of the primary cam and to the top of the bracket 9 thereby opening the gripper for receiving the front end of the roll of band-paper. The gripper instant the latter is delivered to the the triparm drops over the back of the bracket and the end of the roll of paper is grasped by the gripper. During the forward movement of the reciprocating table the triparm engages against the under side of the pivoted primary cam and lifts the latter out of its way without disturbing the gripper, thereby permitting the gripper to maintain a firm hold on the paper during the first portion of its forward movement for unwinding the paper from the roll. The secondary tripcam g is rigidly secured upon the central portion of the main frame in line with the pri mary tripcam and is provided with inclined front and rear ends. When the reciprocating table has completed about one-half of its forward movement, the cutter severs that portion of the band which has been unwound from the supply-roll, and at the end of the forward movement of the table the rear end of the band is arranged underneath the body and head of the box on the mandrel preparatory to being wound around the same'during the subsequent backward movement of the table. When the reciprocating table has completed about one-half of its backward movement, the trip-arm rides over the in clined front side of the secondary trip-cam, which releases the end of the band of paper from the gripper and permits the mandrel to wind the same around the box body and head. After the paper band is released from the gripper the trip-arm dropsover the rear side of the secondary trip-cam and again closes the gripper. During the forward .movement of the reciprocating table the secondary trip-cam also raises the trip-arm and opens the'gripper momentarily; but before this occurs the band of paper has already been severed from the roll of paper, so that no resistance is offered to the forward movement of the severed paper band, and the latter is not withdrawn from thegripper during the'momentary opening of the same. If desired, the secondary trip-cam may be of the same construction as the primary trip-cam.

R represents a reciprocating feed-plate, upon which the end of the paper band rests and which slides in a standard 1, arranged on the main frame over the receiving end of the reciprocating table.

the paper band is guided thereon by guides r, secured to thefeed-plate on opposite sides of the band.

7 represents holddown-fingers secured'to the feedplate.and bearing upon the band, whereby the band is prevented from rising.

r is a detent-plate whereby the band is held against backward movement on the feed-plate. This. detent-plate bears upon the band in rear of the holddown-fingers and is secured .to a transverse shaft rfiwhich is journaled in bearings r arranged on the feed plate. The detent-plate is pressed lightly against the band by a spring 1", secured with its ends to the transverse shaft 1* and one of its bearings. The front end of the paper band projects slightly beyond the front end of the feed-plate when the latter is in its normal backward position. During the lastportion of the backward movement of the reciprocating table the feed-plate is moved for wardly and places the end of the paper band petween the gripper and the opposing gripperace.

.9 represents an oscillating lever whereby a reciprocating movement is imparted to the feed plate. The lever s is pivoted between The feed-plate is in- 'clined toward'the reciprocating table, and

its arms upon a bracket secured to the main Y band has been drawn over the feed-plate the frame, and its upper arm 3 is connected with the rear portion of the feed-plate by a link 8 The lower arm of this lever s is forked or bifurcated and consists of two jaws 8 s 8 represents a trip-pin secured to the front end of the gear-rack on the under side of the reciprocating table and adapted to engage with the forked lower end of the feed-lever for reciprocating the feed-plate. In the normal position of the feed-plate the lower arm of the feed-lever inclines toward the reciprocating table, with the space between the jaws arranged in line with the trippin. During the last portion of the backward movement of the reciprocating table the trip-pin engages with the jaw s of the feed-lever and pushes the lower arm backwaroly, which causes the feed-plate connected with the upper arm thereof to be moved forwardly for inserting the end of the band into the gripper. During the first portion of the forward movement of the reciprocating table the trip-pin engages with the jaw s of the feedlever and returns the same and the feedplate to their normal positions.

8 represents a catch whereby the feed-lever is held in its normal position and which is pivoted to the main frame. This catch is provided with a notch s in its upper side, which receives the jaw s of the feed-lever and is yieldingly held in engagement therewith by a spring 8 arranged on the main frame. hen the feed-lever is shifted by the trip-pin, the catch 8 is deflected, but engages again with the feed-lever when the latter resumes its normal position, thereby insuring the proper engagement of the trippin with said lever.

T represents a vertically-movable cutter or knife-blade whereby the paper band is cut into proper lengths as the same is drawn over the feed-plate. This cutter is arranged transversely above the feed-plate and is adapted to operate in conjunction with a shearing-face t, formed on the front end of the standard which supports the feed-plate. The cutter is provided at its ends with arms t, which are secured to a transverse cuttershaft 25 journaled in the standard. One end of the cutter-shaft is provided with a rockarm t whereby an oscillating movement is imparted to the cutter.

t is a cam secured to the cam-shaft, and t is a connecting-rod passing through an open-v ing in the top of the main frame and pivotally connected at its upper end to the rockarm of the cutter-shaft. The lower bifurcated end of the connecting+rod straddles the cam-shaft and is provided with a' roller t, which bears against the cutter-cam. The latter is soconstructed that it holds the cutter in a raised position during the forward cutter drops and severs the band. The descent of the cutter is preferably aided by a spring 17, secured to the main frame and bearing against a pin i secured to the rockarm 25. The paper band is gummed on its upper side in any suitable manner before it is carried to the feedtable. The cutter is provided on its front side with a holding-down finger t, which carries the rear end of the severed band downwardly between the guiderails and prevents the same from becoming displaced.

u 1/, represent upper and lower burnishing or finishing rollers arranged at right angles to each other and adapted to press the gummed band against opposite sides of the margin of the box-head. The lower roller u is arranged vertically adjacent to the rear end of the band-sup porting rail, with its rear side in line with the rear side of said rail. The upper roller u is arranged horizontally adjacent to therear end of the turning rail, with its periphery in line with the front side of said rail.

u represents a swivel collar or ring provided with ins or studs u upon which the finishing-r0 lers are mounted. The swivelcollar is pivoted upon a rock-plate u by a longitudinal pin 11?, so that the collar can turn transversely with reference to the reciprocating table. The rock-plate is pivoted at its ends by transverse screws it upon a U- shaperl rock-frame u, so that the plate can swing vertically lengthwise of the reciproeating table. The rock-frame is pivoted with its arms upon opposite sides of the carrying-plate by transverse pivots u so that it can swing vertically, and is yieldingly held in an elevated position by means of a spring u, bearing with its ends against the top of the reciprocating table and the under side of the cross-bar of the rock-frame. The rockplate, swivel collar, and rollers supported thereon are normally held in a forwardly-inclined position by means of a spring u connected at one end to the top of the reciprocating table and with its other end to an upwardly-projecting rock-arm u, formed on one end of the rock-plate. During the last portion of the backward movement of the reciprocating table the mandrel leaves the band-rail and the paper box is brought into engagement with the finishing-rollers. The vertical finishing-roller presses the paper band into the corner between the body and the front marginal portion of the head, while the horizontal roller presses the lower edge of the band against the rear marginal portion of the head.

If the paper box tends to exert a greater pressure upon one finishing-roller than upon the other, that roller with which the boX first engages is tilted, thereby carrying the and backward movement of the feed-plate, 1 other rolleragainst theboxand equalizing the and when a sufficient length of the paper l pressure of the finishing-rollers. Inorder to l capable of longitudinal movement in said press the band properly against the rear side of the box-head, the axis of the horizontal finishing-roller must always be radially in line with the center of the paper box. For this purpose the rock-arm a projects upwardly sufliciently so that it is struck by the sliding rod supporting the holdingdisk, while the reciprocating table is in its backward position, as represented in Fig. 23,

The operation of uniting the circular body and the head. of the box is as follows: During the last portion of thebackward movement of the reciprocating table the feed-plate moves forwardand feeds the end of the band of paper into the gripper. The latter is now during the subsequent forward movement of the reciprocating table the paper band is drawn upon the latter, and when a sufficient length has been withdrawn the cutter severe the same. This severed portion of the paper band is now carried forward until its rear end arrives in line with or in rear of the axis of the mandrel. During this forward movement of the reciprocating table the operator places a box-body on the upper mandrel, and. the mandrel-frame is then turned. automatically, so that the upper manfjrel carrying the body will occupy the operative lower position when the reciprocating table reaches the end of its-forward movement. The instant the mandrel carrying the box-body arrives in its operative position the carrying-arm places a box-head against the face of the mandrel, and the holding-disk holds the head in place, while the carrying-arm detaches itself from the head During the ciprocating table the body of the box and the box-head roll over the gummed paper band, thereby picking the same up from the supporting-rail and winding the same around the body and the head. Shortly before the gripper arrives underneath the mandrel during its backward movement with the recipro eating table it opens to permit the front end of the band to be withdrawn from the same and. to be wound around the body and head of the box. WVhen the reciprocating table has reached the end of its backward movement, the finishing-rollers engage against the box and press the band smooth, after which the holding disk is removed and the mandrelframe is given a quartenturn, so as to raise the lower mandrel from the band-rail. During the subsequent forward. movement the operatorremoves the finished box and places another body on the upper or idle mandrel. Afterthe band is wound upon the body and head of the box the upper edge of the band. is automatically turned inwardly over the upper edge of the body by mechanism which is constructed as follows, and which is illustrated. in Figs. 2935:

W represents a rearward extension of the main frame, provided with a table to and a standard VJ on one side of said table.

w is a magazinedisk which rests upon the table and is mounted on the lower end of a spindle e0 journaled. with its upper and lower ends in bearings formed, respectively,

ICC

in an overhanging arm W of the standardand the table to. The magazine is provided w" represents a ratchet-lever pivoted loosely upon the upper portion of the spindle and provided with a pawl w, which engages with a ratchet-wheel w", secured to the spindle.

w is an elbow-lever whereby the ratchetarm is oscillated and which is pivoted at its elbow to the main frame. The upper arm of this elbow-lever is connected. with the free end of the ratchet-arm by a link w while the other arm is provided at its end with a roller w, which engages with a cam-groove w formed in a disk or wheel w, mounted on the main shaft in rear of the standard W. This cam-groove is so constructed that each revolution of the main shaft turns the magazinedisk the distance between two adjacent pockets.

w is a detent-pawl which is adapted to engage with notches in the edge of the maga zine-disk for holding the table against backward movement. This pawl is secured to the upper end of a vertical rock-spindle w, journaled in bearings w on the side of the main frame. The detent-pawl is yielingly held in engagement wth the notches in themagazine-disk by a spring w, secured with its ends to the rock-spindle and the main frame.

to represents a tappet formed on the front side of the cam disk or wheel an; adapted to strike an arm w", formed on the rock-spindle to for throwing the detent-pawl out of engagement with the notches of the magazinedisk while the latter is being moved forward.

X represents a folder-head whereby that portion of the band projecting above the upper edge of the body of the box is turned or bent inwardly over saidedge and at right angles thereto. This head is arranged over the magazine in line with the path of the pockets therein and is secured with its upper end to the arm of the standard by means of a hollow shank 0c. The under side of the folding-head is provided with an annular groove or folding-face 00 which is curved from its outer edge upwardly toward the center thereof.

00 represents a plunger whereby the boxes are carried successively from the pockets in the magazine upwardly against the foldingface of the folding-head. This plunger is ar ranged vertically in line with the folding-head and slides in an opening 00, formed in the table in line with the path of the pockets in the magazine. In the normal position of the plunger its top face is arranged flush with or slightly below the top of the magazine-table, which permits the magazine to be turned for bringing one of its filled pockets axially in line with the plunger and the folding-head. Upon raising the plunger when a filled pocket is arranged in line with the same the plunger lifts the box in said pocket and carries it against the folding-face, which causes the latter to turn the upper edge of the band in-' wardly over the upper edge of the body and at right angles thereto. This upward movement of the plunger is effected by a cam secured to the main shaft and bearing against a roller an on one side of the plunger. After the box is finished the plunger is depressed by a cam 00 on the main shaft and engaging with a roller 20 on the opposite side of the plunger.

4 represents a cylindrical finishing-head whereby the upper edge of the band is folded and pressed downwardly against the inner side. of the body of the box and finished. This finishing-head is arranged to slide vertically within the folding-head and is about equal in diameter to the inner side of the boxbody. After the band has been turned inwardly at right angles to the body of the box by the folding-face it is held against the folding-head a su'l'licient time to permit the finished head to descend and turn the band against the inner side of the body.

is a rock-lever whereby the finishinghead is raised and lowered and which is pivoted between its arms upon the upper end of the standard W.

g represents a rod whereby the rock-lever is connected with the finishing-head and which is arranged in the hollow head and its shank. The lower end of this rod is rigidly I secured to the finishing-head, while its upper end is provided with a groove-collar if, with which the fork if on one arm of the rock-lever engages, thereby compelling the rod to move vertically with the rock-lever, but permitting the same to rotate independent of the rock-lever.

if represents a cam-groove formed in the rear side of the cam-disk w, and y is a rod connected at its upper end with the other arm of the rock-lever and provided at its lower end with a fork if, which straddles the main shaft, and with a roller which engages with the cam-groove if for imparting an oscillating movement to the rock-lever.

if is a spiral groove formed in the rod 3 and g is a pin or screw arranged'in the hollow shank of the folder-head and engaging with the spiral groove of the rod. Upon raising and lowering the rod the pin engaging with the spiral groove causes the finishinghead to turn as it enters and leaves the boxbody, thereby finishing the inner side thereof. After the band has been turned over the body the plunger descends and the box is again lowered into the'pocket of the magazine.

2 represents an ejector-block whereby the paper box is caused to recede from the finishing and folding heads with the plunger. This block is arranged in a recess 2 in the under 2 During the last portion of the downward movement of the finishing-head the ejectorblock strikes the bottom of the box and is forced upwardly into the finishing-head. During the descent of the plunger the resistance of the ejector-spring 2 causes the ejector-block to pressthe box downwardly and strip it from the finishing and folding heads should it have a tendency to stick thereto. After thefinishing-head has been withdrawn from the box the upper annular edge of the lattercontracts slightly, so'that its internal diameter is somewhat less than that of the finishing-head. The rear cam-groove 1 of the cam-disk is so constructed that the finishinghead is moved downwardlya second time i during the descent of the plunger, during which movement the finishing-head bears against the upper contracted edge of the box and detaches the same from the folding-head if the box is stuck thereto, by particles of paste. After the box has been returned to its pocket the magazine is turned so as to bring the next pocket containing an unfinished box in line with the plunger and foldinghead. The magazine-table is provided with an opening 2 in line with the path of the magazine-pockets, which permit the finished boxes to drop out of the pockets.
