To all whom it may concern:

Beit knownthat I, MARK D. KNOWLTON, ot Chicago, iri the county of Cook and State of Illinois, have invented certain new and usefnl Improvements in Box-Jointing Machines',

. (patented in Great Britain on the th day ots April, 1888, No. 5,080;) and I 'do hereby declare that the following is a full, clear, and exact description' thereof, reference being had 'to the' accompanying drawings, andto the letters of reference marked thereon, which form a part of this specification. l v

This invention relates to an improved ma` chine for making the jcintsin the manufacture of boxes or other articles oi paper, strawboard, wood veneer, or similar material, and

lmore particularly yadapted for use in the The invention conslsts in the matterslhere inaiter described, and pended claims.

pointed ont in the ap- A machine embodying my invention .emh braces as its main or essential features-clamping-dies for'pressing or forcing jointingstrlps against or in contact with the edges of. the

- parts to 4be joined after paste, glue; or other.

'the-strip adhesive substance. has been placed between and the surfaces to which itis to be applied, together with means .for guiding or directing to or between said'dies a paper strip from which the individual jointing-strips are severed. `.As far as this main f ealture ot the invention is concerned the. paper strip `may be fed forward to thev dies either by hand or otherwise. A

The machine herein shown embraces as a separate and further improvement an-automati'cally-acting feeding device byA which the paper strip is fed forward between the dies` each time the latter are lactuated for clamping the strip against the parts to be joined. The particular machine herein shown embraces, furthermore, as an additional improve- 'nientan automatically-acting cutting device for severing 'the jointing strips or pieces from the'continuous strip and for applying ad hesive substance to said strip. .The devices for applying adhesive substance are not es'' sential in a machine embracing-,the main features of. construction above illustrated, inas-v much as the stripsmay be previously'coated with adhesive substance, which' is allowed to dry and is moistened byt steam or otherwise Vshortly before it is applied to the'parts to be joined, or 'paste or glue 'may he' applied by hand -tothe jointing-'strips or to the parts to be joinedt The employment of. continuously applying pastecr glu-e` to the strip das'it is ted to the clamping-dies is' for severalreasons preferred, anda machine embracing devices for this pnrpose is herein claimed as new, as are certain parts of the machine relating to the paste-applying devices. The. machine may be-employed for joining the edges of paperor'straw-board articles either when the parts to be joined are in the same plane ori-when theyare arranged at an angle with cachot-her.

-The particular machine shown is for j'oin- I ing the-sides ot straw-board boxes, 'and the dies are thereforevmade one concave andthe other convex and withatfaces arranged at an angle with each other.

In the 'machine herein clamping-dies is .constructedlto reciprocate inapplyingthe jointing-strips, whilel the 'other remainsimmovable, and the paper strip illustrated one oi' is severedby a knife or cutter upon the ma- ,chine-frame acting in conjunction with acutting-edge of or upon the'movabledie. In saidy machine, furthermore, the non-reciproeating die or anvl-block is bodily movable or adjustable with relation to theinachine-frame and the stationary cutter supported thereon,

andl said non-reciprocating die or anvil-block is connected with4 the actnating devices by which the paper is f ed forvl'ard in suchl man- 'ner'that the extent of theforward movement of the paper strip will bechanged by moving the said adj ustable die to correspond with the width of the sides of the box' to be' joined by the strip, so that a jointing-stripot the right length will in 'every instance be applied to the box.

rco

'lhe machine herein shown is furthermore adapted to be actuatedby a footlever; but a machine embracing similar features of construction may be operated by power or by the operator actingthrough other means than the foot-levcr.

Fig. 17 is asectional viewof the same. Figs. 18 and 19 are sectional views of the same.

As shown .in the said drawings, the mai-n frame of the machine is formed by anintel gral casting embracinga horizontal bedLplate A', a vertical part br standard A at one end of the bed-plate, and a'flat vertical side plate or web Aarranged at one side of the bedplate and connected at its margin with the.`

standard A'. Tothe bed-plateA are attached legs As, bywhich the machine is supported. Upon the frame thus constructed the several operative partsof the machine are mounted or sustained. i

B is a non-reciprocating die or stationary 1 anvilblock having the form of a bar or rod .arranged horizontally and supported in the standard A somewhat above the bed-plate A. The said anvil-blockfB extendsl atits end through the exterior vertical face of theframestandard A', and the projecting part forms the working-su rface of the die or anvil. The

-said'anvil-bloclcB is fitted to slide longitudinallywithn its seat 'or bearing inthe stand' ard-A A', s o. that its end portion may be 'cx-l tended a greater or less distance from the faceof the said standard. In a simple. and convenient construction of the'anvil-block herein shown the latter is made semicircula-rf upon its under face and provided at its outer end with flat working-faces b b, arrangedfat right .any "es with each other, with their meet ing edges upward. The anvil-block may .be held or clamped in place in any suitable manner, the means for clamping, as herein shown, consisting of a clamp-bar B', resti-ng at its outer end against a laterally-projecting .arm `aof the standard A and bearing at its of the standard A", and being provided with.

a V-'shaped notch or recess c in its under surface, forming the working-face of the die to engage with the oblique surfaces b b of the anvil-block. The die C is attached to avertically-movable slidev Cf,` mounted in guides a a. upon the standard A'. Said reci procating die acts,in conjunction with a stationary knife or cutter D, to sever the separate joint ing-strips from the long or continuous strip fed to the machine. Said stationary knife or cutter is located' over the stationary die`V block in such position that the said strip is fed or guided over said die-block as the strip isadvanced between the dies. flhe cutter is herein shown as held or supported in a'removable plate D', which plateis' botd to the frame-standard A', and is provided with an opening or passage d, through which tl estrlp passes to'the dies, as will hereinafter more fully appear.

L The slide C', which supports the die C, is in the machine illustrated moved vertically for actuating the movable die C by the following devices:

E is a heavy and strong bell-crank lever mountedv upon a pivot e, which is 'inserted V through lugs or bearing a2 a?, located at 'the upper end of the standard A and at. the ini ner face thereof. The said bell-crank lever E is provided with a short 'horizontal arm E',

' los iro which engages a recess c in the upper part o f the slide C'. Said arm E'is'herein shown as provided with a flat spring c, arranged to bear upwardly against the upper wall of the ,opening-c" to take uplost motion in the parts.

Said bel1-crank lever E is provided with a l co.

second arm'E2, which extends obliquely down, l

ward to a-point near the bedplate A.

li)s is a ,foot-lever pivoted at its upper end to the'machine-frame by means of a pivot-pin e, arranged near the lower end of the stand- -ard' A. To the upper end of said foot-lever is attached a rearwardly-extendingrigid arm E", which isconnected with the lower end of the. lever-arm E2 of the bell-crank lever by means of connecting-plates E E5. When the lower end of the footlever Es is thrown backwardly, the lower end of the lever E2 is throwrf upwardly andinwardly, and the slide C and upperdiethereby depressed. When the footlever is thrown forward, on the contrary, the

- die is elevated. I have herein shown a bar E7 attached lo the foot-lever, sliding in a bracket Es upon the bed-plateA and provided` with a head e", as employed to limit the forward motion o`f the foot-lever. The' continuous strip of paper to be fed to the machine for making the joints is mounted 1o upon a reel F, sustained upon an arm F' at-- tached to the frame.

l f in the drawings indicates the paper strip. G is a folder which acts upon said strip after the latter leaves the reel to double or crease i 5 the same in its middle, sol that it willV take and maintain a V shape at' the'` time itis intro, duced between the clamping-dies.

Il is a pastngroller, the periphery-of .which is made of V 'shape to lit within the creased zo or folded lower surface of the strip, andfH'V is apresserfroller for holding the strip incontact with the said 'pasting-roller.'

The paper strip is carried forward or .fed to the clamping dies after leaving the pasting- 2 5 roller by feeding devices acting to gine an iutermittent forward mot-ion to the strip', whereby the end of the latter isea'rried rapidly er quickly forward between `the clam pin g-dies 'and over the margin ofthe box sides placed i 3o over the stationary die and remains immovable while the dies are being brought to getlier'and the jointing-piece to beattached to the boxis being severed from the continuousstrip. The said feeding' device in its main or`esse'ntial features comprises a recip' rocating gripper 'which engages and carries forward the paper strip in its forwardmovement and becomes released fromtlie strip at he limit of its forward movement, so asto l' 4o move backwardly without-producing any cori responding movement in the strip.

'lhe'partic lar feature of construction herein illustrated in the feeding device and means for guidingthepaper strip to the 'same and from saidfeeding'device to the clamping-dies are as follows: j

l, Figs.. 1, 4,5, 6, 7 and 48, is an L-shaped guide-plate -upon which the 'main operative parts of 'the feeding device are sustained.

a vertical Bange I'A at one of vits edges, which flange is provided witha longitudinalguideslot i, in which the reciprocating gripper isheld and guided. Said guide-plate is also pro- 5 51vided with an arm or bracket I, by which it is secured t'o the machine-frame. The main part ofthe guide-plate I is arranged beneath the path of the paper strip, 'so that the said strip passes lon gitddin'ally over said plate par- V6o allel with the guide-slotfz'- thereof. -The said gripping' device comprises a sliding plate J,

arranged vertically, against the plate I', and held in place by means of aplat J', located at the opposite or exterior faceA of the said plate andconuectedwith the plate-J through the slot: z'. A fillingpiece j is desirably attached to the .pl:*e J. within the said slot.

Said plate I is herein shown as provided with J2. is the lower jaw of thc gripping device, said jaw being arranged centrally beneath ,the path of the paperstrip and provided with a sharp or narrow beari-n{,f-e'dgejI to engage the inner surface of the strip at'tlxe upper part orcrease of the same. 'lhe said -jaw .1 of .the gripper is connected with the lower edge of` the sliding plate 'J by a horizontal arm orplate ji,- locattd adjaccntto the plate I and with its upper surface a snflicient distance below theedge j' of the lower gripper .to avoid coming in contact with thecorner margin of the folded orfV-shaped s'trip pass` ing over it, Fig. 8. In the simple and conven-A ient constructionof these parts hereinshownthe plate J, the plate f3, and the gripper-jaw J are formed or bent from a single piece of metal. l Jsis the4 upper or movable gripper-jaw, whichs arranged above thelower jaw J 2 therei maybe-either engaged with or lifted free from the-said .lower jaw. In the particular movable 'gripper-jaw .Tsis formed by orv upon the end of the horizontal lever Ji, which is mounted upon a pivot-pin js, affixed-in the sliding plate J, said lever J being arranged horizontally and its` pivot js being arranged to overhang the path of the paper strip. The working-face of thesaid gripper`-j aw J-s is here hard metal serrated or ronghened to more .posi tively engage the strip.

J5 is an arm for actuating the gripper-arm J 4, said arm J 5 being attached to and extended upper end a horizontal crank-pin 74;

Ina device'embraclng the general features ofvconstruction above set forthA the reciproeating .part or plate carrying the grippingjaws and the *ansthemselves may be moved by any'suitable actuating devices. As a sim- -ple and desirable construction of the parts however,"they are herein shown as so coning plate J and the gripper-are driven by actuating devices engaged with the upper end of the lever-armJfalon e. Forthis purposelprovide frictional engagement between the said plate J -and'its guide, tending to retard the movement of the plate, so that when pressure is applied to the upper e'nd of the arm Jf'? in a direction to carrythe said upper end of the arm forward the ,(.g'ripper-arn J4 will first 'be depressed, after which a continuedforward carry the-sliding plate and gripper-jaws bodily7V forward. Similarly when the pressure is ap- -pliedto the upper end of the lever J5 to move -the same baekwardly the jawswill first be opened, and the entire gripping device will then be moved bodily backward, Anyone of .a great number of well-known devices maybe employed for producing frictonal engagement between the plate J and the guide-plate I'. The device for this purpose hereinsliown.'

of and is 4made vertically movable, so thati'tf embodiment of the invention illustrated the inzshown as formedfby a separate piece of upwardly from the'arm J4, and having at its I re f ,structed that the reciprocating grpper-ca'rryt pressure upon the upper end ofthe arm J 5. will i Fign 5, comprises a flat springj, restngat its J in forcible contact with the' opposite sidesof the guide-plate I', and by turning. the.

screws ij the pressure of the spring may be adjusted as found necessary or desirable.

Devices heroin illustratedfor actuating the feeding mechanism are madeas' followsz.- K is a rocking lever which is pivotally supported upon ashaft k,- mounted in the flange or web A2 of the machine-frame at a point near the rear endet the machine.' 'Adjacent toits pivetal pointthe lever K is provided with'a rigid arm-K,'witl1 which arm isengaged a bar K2,

i the opposite or lower end of whicbis pivoted to the foot-lever E. The rocking lever K is connected withthe lever-arm Jl5 of the feeding device by means of a connecting-rod K3,

- engaged with a pivot k uponthelever K,and

with the pivot-pin j* of the said arm J". The upper end of the bar K2 is not'pivotally con-l nected with the arm K. ot' the lever K, but

said arm Kis provided with a stud kwhich engages a notch '7c3 in the upper end of the said arm, and said lever is held in position for the engagementof said notch with the said stud by .means of a supporting surface or abutment upon the machine-trama, herein shown 'as formed byan anti-friction roller K4. The lever K is held at the rearward limit of its movement'by asuitably-applied spring, so that the forward movement only of the gripyping device is given by the action'ot' the bar K2 and foot-lever, the rearward or. return movement of the gripping devicelbeing alfforded by said spring.v In the particular con- .struction herein shown in these parts'the shaft lc of the lever K is rigidly attached to the arm and extends through'and has beari/ng in theframe plate or web'A. 'The said shaft, furthermore, extends outside of the web A2, and is :provided at its outer end that said stud will swing forward-out of the' with a collar k", tov which is attached one end of a spirally-coiled spring K5, the opposite end of which is attached to the frame. Said spring tends to hold the rocking 1e ver K normally at the rearward limit of its movement and acts topromptly return the gripping devices to 'the starting-point of ythe same after the bar K2 has been drawn downwardly or retracted. The stud k2 ofthe arm K is so located with reference to the bar K2,

notch )as of said arm' after the arm has -been lifted a short distance, and'when thejlever-K" has been swung forward -a sutiicient distance to give the movement in the gripping devices necessary Vfor properly feeding `the paper strip the said bar K2 may be held from being carried forward awayfrom'the 'roller K4 bymeans of a roller K6, mounted upon the shaft c,Fig..l5, orothcrwise. After the notch k3 of the bar K2 is 'released from the stud k2 V For applying joining-strips in the making of boxes 'of diderent sizes itis .obviously de.- sirable that thedistance to which the strip is fed forward past. the cutting or severing devices at each Vadvance movement of the4 feeding mechanism should be capable of va .riat-ion in order that the length .of the strip used upon the box mayv correspond'with the depth of 'the same. In connection with `the stationaryA die or anvil-block, Vwhich isuiovable. bodily tolaiford-agreater or less distance between the cutting-off mechanism and the I have provided 'a connecting mechanisml be tween such movable an vil-block and the parts by which the feeding devices are actuated, whereby the movement ol' the block. a certain distance will 'produce a corresponding change -in thethrow of the gripping-jaws, whereby the length of -thev strip fed forward .at each reciprocation of the gripping-jawswilli-correspond'approximately with the length of the end of the block, as hereinbefore described.'

exposed part ofy -the an vil-block and thel joint to be made.

Devices herein shown for the purpose above described are constructed as follows: Y The pivot-pin la', which connects .the rock- .ing lever K with the connecting-rod Ks,in

stead of being immovably secu red. in the le' ver K, is adapted for' longitudinal movement uponsaid lever. For this purpose the said pin is herein shown as mounted upona sliding block L, engaged 4with .a guide groove It inj the said lever.

A L. is a bell-cranklever, which 'is mounted upon a pivot Z, located'beneath the inner end of theanvil-block or bar Band provided with an upwardly-extending arm having engagement with'th'e block and with a'horizontal arm, thefree end of which is .connected with the said sliding'block L by means of a connecting-rod L. 4 bell-crank lever L' and thevanvl-'block B is herein shown as formed by means of a plate l?, attached to the side 'of the said anvil-block and provided witha vertical groove l2, which engages a pivot-pin l in the upper end of the vertical arm of said bell-crank lever; When ,the-said anvil-block connected with vno the pivot-pin k o l the lever K in the manner 'described is thi ust outwardly, said pivot-pin will be carried or moved upwardly away from the'shaft. of the said rock-ing'lever. K, therebyl giving a greater throw to' .the said pivot-pin andinc'reasing the throw of -the gripping devices. When, on the contrary, the anvil'- ,block is moved inwardly, the pivot kis moved inwardly upon the rocking lever 5K,

thereby decreasingthef throw of said pin',- k

and giving aless movement in the gripping devices a'nd decreasing the distance through' which the paper strip is fed forward at eachaction of the feeding mechanism,

The particular construction herein shownV in the .guide-plate I .for guiding the paper stri p f from the passing-roller to the gripping devices and from saidgripping devices tothe clamping-dies is as follows: At the rear end ofI the guide-plated is located a/rigi'd Vplate 13, ari'nnged at right angles with said guideplato 'and extending over the path of the paper strip. Said plate Is is provided in its lower edge with a V- shaped notch 111 t-o engage the upper surface of the strip. Upon the end of ,the plaie I opposite the said guide-plate l3 is located a V--shaped guide-bar I, which also extends 'over the strip and engages the upper-surface thereof. Along the uppersurface of the plate I, at thecentral line of the paper strip, is located a longitudinal guidenient of metal, the upper margin of which is arranged in approximately the same ho'ri-' zontal plane as. the upper end of the lowergr-ippiug-jaw J 2,'and which is constructed to engage the under surface of the paper strip within the seam or crease'thereof. The purpose of this Asaid guide-strip is tohold the paper strip accurately in position with relation. to the gripping devices, setbatthecrease in the paper strip will come exactly over the lower gripping-jaw, and thus preventa distortion of the strip 'when Athe same is gripped be- :tween the jaws; The said strip l is herein shown as supported by being attached to a plate i2, which is secured 1to the plate I at the end of the latter at which the paper strip enters the guiding devices. Atits opposite or forward end the guide-strip is unsupported, the plate I being'cut away beneath the strip at this point, so as to form an oponing or. recess 16, Figs. 4 and7, within which the upper edge or corner of the working-face ofthe anvil may enter when .said anvil is thrust inwardly for operating upon shallow boxes or covers. .-'lhe said guide-strip I5 may,

` however, be 'sustained or held`from lateral movement by engagement with the lower 'gripping-jaw J2, at one side of which said 5 Strip passes., A preferred construction in' --these parts is-illustrated in.Fig .'8, in which the.V guide-strip is shown as beveled at one side 'only togive it a shar '/or narrow edge, lo.

tact with the gripping-jaw, while the said jaw has a'.similar shape,l)ein1g..made' dat at its-- stri p l5, consisting of a narrow strand or fila cated at that face ofthe strip which is in con-V ing with the'jaw J? a notch ip which the said g'uide-strips'isheld and `guided." The said notch will, however, be made slightly deeper than the wid th of the guide-strinse that the` 'upper gripping-jaw will act against the lower l jaw J2 without thrusting saidguide-strip downwardly against the bottom of said notch.l

'I7 17 are two guide-rods, which are located Vabovethe guide-plate I, one at each side of the guide-strip I5, at such. distance apart as to engage the upper surface of the paper strip near the lateral margins thereof. `Said` guide-rods aid in keeping the strip accurately A in position with relation to' the gripping-jaws of the feedingmechanism and are also of use to p revent. the sidesof the folded or creased vpaper'pstrip from bendingor curling up on account of the moisture in the paste or glue applied thereto. The said gndefhars 17,17 may be attached to or supported from the plate I in any-desired manner. AAs herein illustrated, they are inserted and secured to their ends in the guide-plate 13 and guido-bar '14. At its 'end nearest the clamping-dies the plate I is herein shown as provided with av V-shaped extension 18, adapted to enter the opening d of the plate D', by which the stationary cutter D is directly'supported. Said plate 18 serves to guide the paper strip until l the latter reaches the said cutter. The projection I8 is herein shown as provided. at. its

top witha vertical flange l, the upper edge of which rests against the top of the said opening d. The sides ofthe said projection I8, together with the flange I, serve tohold the ends of the guide devices' accurately in position with reference to the knife and the clamping-dies by their engagement with thewalls of said opening d. l have found thatin the use of rollers I-I l-I, suchas are herein shown, for applying paste ,to the paper strip, when' .the said strip is carried or moved rapidly forward by the action, ofthe feeding mechanism described the impetus acquired are' turned by the paper is liable to cause the said rollers to continue to turn in a'manner to thrust the paperv forward'after the gripping#y To avoid this result,l I soconstruct the upper roller Il that it may be lifted to free it from the lower roller l1, andi provide means whereby p the -upper roller will be automatically lifted free from thel lower-roller-at the moment the forward movementof the-gripping-jaws is terminated. When the partsare thus constructed, the paper strip is released from the pasterollers before the latter have an opportunity to act upon the strip in a manner to carryit by the paste-rollers as they A 1 I 5 jaws have completed their forward movement l pm h', secured upon one of two parallel arma lll2 H2, which are rigidly connected with each other and are mounted upon a rigid ivotpin h2, axed in the frame-plate A. the end'of one of the arms ll is formed or attached an arm or striker H3, located in position to engage the stud k2 of the rocking lever K when the said stud has nearly reached ihe upward limitof its movement. 'When the said lever K is actuated by the notched bar K2, therefore, the arms 112 l-lA and the roller H will be lifted at the moment the feeding devicev reaches the forward limit of its movement land said roller II will be supported free from the paper strip until the foot-lever is swung rearwardly andv the bar K2 retracted' preparatory to another and succeeding 'operation of thc machine. The lower paste-roller H is constructed to enter a tank or receptacle H4, containing paste or other adhesive sub stance, so as to become coated upon its margin in a manner heretofore common and well understood. ll5 is a. scraper arranged to tit against the V-shaped periphery of the said feed-roller to remove the surplus adhesive substancetherefrom.

The cutter or shear-blade D, employed to sever that part of the jointing-strip applied to the box-walls from the main or continuous part of the strip in the manner hereinbefore stated, acts in the-particular construction illustrated in connection with the cutting edge formed at the rear surface of the movable clamping-die C as the movable -die descends toward the work. Any separate knife or cutter on the movable die is rendered unnecessary in the particular construction shown by making the rear face and working-surface of the movable die of hardened steel.

The stationary knife or cutter D is herein shown as made preferably of thin or sheet metal and of inverted-V shape, said cutter being secured to the plate D by screws, the heads of which are shown. A plate M4', secured to the plate D above said cutter, aids in holding the same in place. Saidplate M is provided with an opening m', Fig. 10, through which the stri p passes over the knife. The forward or advance edge of the cutter forms the cutting-edge thereof, and the said cutter is held up to its work by screws placed behind it or otherwise.

The movable die' C may be constructed'iu any suitable or preferred manner to aiord a suitable cutting-edge at its rear surface. In the particular construction herein illustrated theworking-surface of thedieisformedin acylindrical block C2 of hardened steel, tholower surface of which block 'is provided with a V- shaped notch corresponding in form with the opposing surface ofthe die-block B. The rear or inner end surface of the said hardened block moves in contact with the face of the cutter D, so that the edges of the notch act, in connection with the said cutter, to sever the paper strip. l have herein shown the block C as held within the head of the die by pon i splitting the latter vertically-anu inserting one or more olampscrews c3 for holding the split parts together. A screw c, inserted in t e head and overlapping the die-block C, serves to hold the gu tie-block from being thrust endwise out of the head and to adjust said block with reference to the stationary cutter.

In Fig. 13 is shown the cut and scored corner of a box-blank before the jointing-strip is applied to the same, and in Fig. 14 is shown the finished corner after the jointing-strip has been applied. In the operation of the machine the operator sits or stands in front blank, split and scored, as shown in Fig. 13, upon the upper surface of the anvil B below the movable die, the sides of the box being bent or held approximately at`right-angles with the bottom when the blank is placed upon the anvil-block. When tho corner of foot-lever E3 is actuated, with the result of quickly thrusting forward the end of the strip over the edges of the blank and then depressing the upper die to sever the strip and forcing itinto contact with the surface of the blank. The'folder G herein shown comprises a curved plate G', which is bent into U form, with its side walls arranged at some distance apart at, their rear ends, but brought together or parallel with each other at their forward ends, so as to gradually bring` together the margins ofv the strip, thereby bending the paper strip into U shape Aand to then fold or crease the strip as it emerges from the folder.

It will of course be understood that a previously-prepared gummed strip may be employed in the machine shown, in which caso the pasting or gluing device .shown will be used merely to apply water to the strip foimoisteningthe gum or glue thereon. Obviously means other than the particular gluing or pasting devices shown may be employed, either for applying paste or glue to the strip or for applying water toa previously gummed or pasted strip, without departure from my invention.

The machine herein shown illustrates one practical embodiment ofthe main features of my invention, which latter may obviously be carriedout in a machine differing in its details of constru ctiou from the particular one herein shown. One of the main features of the invention is embodied in a construction embracing a clamping device and means for creasing or folding the strip before it is fed ing and folding devices m/ay be made otherwise than in the particular manner shown, and other features of the machine illustrated may be omitted without departure from my invention-as, for instance, the paste or glue may be applied by hand instead of automat-ivcally by the machine, or the adjusting devices of the same and places the corners of the box-- tothe clamping device; and/as far as this partv of the invention is concerned the said clamp# the blank is thus held upon the block, the
