Be it known that I, WALTER RICHARDSON, a citizen of the United States, and a resident of the boroughl of Manhattan, city,

county, and Stateof New York, have invented certain new and useful Improvements in Apparatus for Applying Fastenings .to Envelops, &c., of Which the following is a specification.

My improvements relate to means for equipping commercial packages, envelops',

and the like, with fastening devices of the class in which a pronged eyelet clasp on the receptacle part is used in congunction with a perforation formed for its reception on the' flap to secure the latter in closed relationship to said receptacle part ina manner now well known in the art.

This appiieation is a. divisin 0f that filed f by me May 10, 1916, Serial No. 96,693, in which'provision is made for simultaneously applying the clasp, reinforcing the flap perforation by patches and making an'imprint on the latter. The present lnvention relates exclusively to the means for feeding l and applying the pronged eyelet clasp to the receptacle portion pf the envelop or similar package, and consists in the specific construction and arrangement of parts described and claimed herein, whereby the pronged eyelet clasps are selected and fed antomatlcally to eyelet-upsetting mechanism of pe'.

Fig. 31, is a view like unto Fig. 9, on the same sheet of drawings, showing the reverse position of the clip escapement and the release doors open, the latter having been omitted from Fig. 9, except as indicated therein in dotted lines.

In the drawings a, a, represent the basic frame or table of the machine supported on legs a', c. Looking from the front of the apparatus, as in Fig. l, the cam shaft C, may be said to extend transversely across the table a., being mounted .in bearings a2, c3, and being held against longitudinal movement by the cams C, C2, which abut against the inner sides of said bearings 1.2, a2, and act, in this respect, as retaining collars on the cam shaft C, for the purpose designated.

Upon the right extremity of the'- cam shaft C, is loosely mounted a power pulley P, the hub of which is formed with an annular groove p, within which rests a detent c,

' vmounted upon a collar c, rigidly secured on the end of the shaft C. Thus the detent 0, allows the power pulley P, to rotate freely on the shaft C', while holding it against longitudinal movement thereon.

Splined to the shaft C, as shown in Fig. 2G, so as to be slidable thereon longitudinally between the right hand bearing a2, and the power pulley P, is the clutch sleeve 0*, formed with jaw teeth c5, for engagement with cor- A respondingl jaw teeth p, on the left hand side of the hub of the power pulley P. In

Fig. 25, to which reference may be had for a clear understanding of the power clutch mechanism, the jaw teeth c5, and p', are shown` in solid lines as out of engagement because the clutch 'sleeve c4, is retracted against the resistance of the compressible spring c6, which is seated 1n a recess formed for its reception in the lower part of the journal bearing a3, and which tends constantly, by its action on the plunger c2, to

thrust the clutch sleeve c4, into engagement with the hub of the power pulley P, to thereby rotate the'cain shaft C. The clutch sleeve 0*, is held in its retracted position by a spring latch or bolt I), which engages normally with an annular shoulder c, on the clutch sleeve c4, but which, when withdrawn by the depression of the foot pedal or tread B, acting through the medium'of the connecting rod b', and rock lever b2, (against the resistance of the retractile spring Il, see Fig. 2) on which the bolt b, is mounted,.releases the clutch sleeve to the impulse of the compression spring 0"'. lll/Then the foot pedal B, is released the spring 1), .returns 'the treadle and connections to normal position.

with the bolt Z), (which may be in the form of a roller) again protruding into the path of the cam portion 042, of the clutch sleeve shoulder 041, so that by its continued rotation with the shaft C, the cam sleeve 0*, will force itself out of engagement with the hub of the power pulley P, thereby releasing the cam shaft C, until the treadle is again depressed to release the clutch sleeve and effect another cycle of operation,-it being undervthe apex of the cam portion G42, of the clutch sleeve c2, as shown in Fig. 27.

The left end of the cam shaft C, is provided with a hand wheel (-8, to facilitate the turning and manipulation of the shaft and cams for any reason when the clutch sleeve 04, is not in engagement with the hub of the power pulley P, 'as for the purposes of inspection, cleaning dies, etc. In such case the clutch sleeve c4, is positively held out of engagement with the hub of the power pulley by a cotter pin c", inserted through a hole 01, drilled in the clutch sleeve c, and into engagement with a hole c, inv the cam shaft C, as shown in Fig. 26, or by any other mechanical expedient. .The hand wheel 08, is made of such Weight and proportion as also to act as a fly wheel to steady and complete the rotation of the cam shaft.

The cams C', C2, Cigare rigidly attached. to the shaft C. Cam C', actuates, through *the medium of the cam lever D, the inner thereto; while the cam C2, actuates, through the medium of the cam lever D3, the ejector punch, which punches the central clip hole through bothreinforcing patches and through the envelop flap after they are applied thereto, and then effects the ejectment of this central waste through the inner patch die I, aslset forth in my concurrent application hereinbefore referred to. The cam. levers D, D2, D3, are of the second order, being fulcrumed to the table (a, at their rear extremities, as at al', d2, cl3, the power being applied to their medially positioned cam pins'which-.protrudefinto the respective grooves of the cams C', C2, C, and being transmitted by the outer or front ends of said cam levers, as above intimated, to the patch dies l, K, printing plunger N, and punches connected therewith. A fourth cam C*, also rigidly attached to the cam shaft C,

is the patch strip 'feed cam which actuates the mechanism by which the patch strips .9, s2, are drawn through the apparatus.

The bifurcated forward end of the cani lever D, straddles the hollow patch tube l, vwhich is mounted slidably in the bearings z, and both of which, in the construction shown in the drawings, torni part of the table bracket secured to rigid extensions a, and n.22, or the table or base a.. rlhe'said forward end of the cani lever D', rests between a collar i, and a lateral extension arrn 71"., both ot which are rigidly attached to the die tube l.

The support for the anvil o, for the clip riveting or eyelet punch r, is formed by a forward extension of the ndie pla-te j, which is secured to the outer side of the bearing block i2, forming part of the bracket on which the die tube l, is mounted. The ineans of securing the pronged and eyeleted clip t, shown in Fig. 23, to the envelop body will be understood most readily by referring to Fig. 2l, which shows the relative positions of parts prior to the riveting action, and to Fig. 22, which illustrates the latter.

The eyelet riveting punch R, considered .as a-Wliole, is rigidly mounted on the extension arm 2", heretofore described as rigidly attached to the die tube l., lts operative end or shank r, is further centralized and supported by passingthrough. a bearing plate 1 u, (Figs. 2l and 22) secured rigidly to the bach of the lower extremity of the. channel standard ll, which at this point is formed with a. recess M4, extending through it into which the shank r, of the punch R, protrudes 'when vadvanced as shown in Fig. 22. The 'punch proper, rx, is tubular, and preferably formed by inserting a tube-rx, in the drilled end of the shank '11, as shown in detail in Fig. 28, an axial recess 71', of less diz-imeter-than the punch tube rx, being also drilled in the Shank 7', for `the compressible spring r2,

which bears upon the head r3, of the centra-lizing` pin r4. The diametery of the bore of the punch tube r* and of the centralizing pin r4, Whichts it are less than that of? the spring recess 71, so that the inner end of the punch tube rx, forms a shoulder against which the head r3, of the centralizing,r pin r, is held normally by the spring r2, said head being of nearly the same diameter as that of the spring recess r. The function ot the centralizing pin ri, is to' support, forward and present the lowest clip t, in the feed channel u, to the upsetting die o', et the anvil o, during the vvorlz thrust of the punch lit. rlhis itdoes byentering the eyelet of the clip t, and supporting the latter untilthe end of the centralizing pin 1"-, contacts with the upsetting' anvil o', when the continued advance of the punch lt, causes the compression spring r2, to yield to said pinvri, and allow in a bearing u,

with vthe result shown in Fig. 24, in a` manner Well known'in the art.

The punch R, may itself bc made laterally adjustable and horizontally adjustable upon its supporting;1 erin z'-by resort to any desired or well known mechanical expedient, so that I do not limit myself in this respect, the Inain object being to furnish means whereby both punch R, and feed channel standard; U, may be adjusted alike in position related to each other and as related to the relatively Fixed axial positions ot' the dies and punch l, K, and R. As shown in the drawings by way 'of illustration, referring particularly to Figs. 2l, 22, and 29, the punch R, is mounted in a split box' 2, positioned in a longitudinal rectangular' slot i, formed for it in said supporting arm I, which is also provided with binding screws e, e, arranged to contact with the upper halt' of the box e, at any position to which the bor; rnay be adjusted in said longitudinal slot 27"". The binding screws e', 2f', are designed to secure the punch R, rigidly tothe supporting arm it. 6, is a collarupon the punch lt, which facilitates the positioning of the punch accurately upon the arm it, as related to the channel standard Uf The fastening' clips t, are ted `to the rivet punch R, through the channel u, into the upper end of which they are ted by the rotable conical portion ot' the hopper V, mounted upon a shaft V, which is journaled supported upon the upper end of the channel standard U, and in a bearing o, on the upper end of the standard V2. The bearing o, is made adjustable horizontally, toward or from the front of the machine, upon the top of its standard V2, by any suitable ineens, as by slots fv, c, and screw bolts 122,412, as shown in Figs. 16, and i9; and tlie channel standard U, is made correspor'idingly adjustable by being mounted near Aits lower extremity upon U', formed with an elongated slot u2, through which a' boites, passes to secure the foot piece U, and standard ll, adjustably to the upper side of the bearing 1i", on the bracket a'. 1 The positions of 'the :toot piece U', and channel standard U, are-indicated in dottedlines in Fig. 20.

The object of provision for the horizontal adjustment of the eyelet-riveting punch R, and the channel standard U, andbearing1 e, on the standard VE, is to provide for the changing' of these parts with relation to the patch .dies l, and K, to compensate for Variations inv length of the envelop ilapsto the bodies of which the clpifastenings are to loe applied.`

a foot piece IThe bearing u', for the inner end of the feed shaft V', is formed in a platefVs, a-ttached to the upper ond of the channel standA ard U, said plate. V3, being formed with a Hat vertical surface 1,,'facing the inner side of the rotatable` portion V, of the feed hopper, and with. the receiving hopper n", into and through w ich the clips are dumped into said rotatable hopper V, as will be understood by reference more particularly to Fig. 5.

This figure. as well as Fig. 13, show the 1 manner in which the rotatable portion V, of the hopper is yieldably mounted on the inner end of the shaft V'. That is to say said portion V, is not secured to its shaft V', to rotate positively therewith under' all conditions, so that, in the event of a clog or jam in the feed between the face plate V3, and said rotatable portion V, of the hopper the latter will cease to rotate with its shaft V', thereby obviatiner damage. This result is attained by mounting; the hub v5, of the rotatable portion V, on a portion e, of the shaft V', formed with a shoulder o7, against which the hub fc5, is pressed normally by a spring Us, held in position on the threaded end o, 'of the shaft V', by a thumb nut om, so as to be compressible more or less tightly against the outer face otl the said rotatablel conical section V, of the hopper. Hence, obviously, said section V, is held to rotate with its shaft V'. only b v the frictional r stance afforded by the elastic resilient pressure ot' said spring` ns. so that when the resistance to rotation with the shaft V, encountered by the conical part V, is greater than the frictional resistance exerted by the spring: o, the otherwise rotatable conical part V, will be held/stationary with the face plate V i. and consequently the portion fr, of the shafty V', will simply slip around within the hub u, of said conical part V. Under such conditions it is needless to say that the conical section V, may be readily loosened upon the shaft V` or possibly removed, so that the cause of obstruction may be quickly ascertained'and remedied without danger of injury to any part. ofthe apparatus, and without delay or serious loss of time.

Theft ed shaft. V'. is held against longitudinal movement by its shoulder u". re.-.in against one side of the bearing` 'u". and by a collar y1112, secured to the shaft V'. and resting against the other side of said bearing u', as shown in Figs. and 1.3. A fixed pulley w13. 'on the shaft V'. atl'ords means whereby the conical section V, of the hopper may be continuously rotated at a moderate speed.

lVhile l have thus provided as above set forth for any unforseen obstruction to the operation of the feed hopper I reduce dan-v ger thereof to the minimum degree by my means for, and method of, feeding the eyelet clips to the delivery channel u.

By reference to Fig. 12, it will be seen that the inner edge of the conical section V, of the feed hopper is formed with a series of equi-distant inclined slots o, the open sides of which are opposed to the flat. vertical surface c3, of the face plate V3. The shoulder ci, on 'the shaft- V',holds the rotatable section V. so that its slotted edge is positioned, say, one sixteenth of an inch (less than the depth of the eyelets but greater than the thickness of the prunes) 4from said on .iosed surface ai@ of the face plate V3, thus creating van annular space r1, between them suticient. to accommodate the prongs of the clips t, but not sutlicient to admit. the eyelets of the clips, which however are free to ente-r the slots vu. As a result of this construction the rotation of the conical section V, causes some of the clips to enter the space'fvl". with their eyelets projectingq into the slots c, and to be arried around to the mouth u, of the channel u, said mouth U5, being gformed in the face of the yplate V, indicated in dotted lines in Fig. 12, and shown in solid lines in Fig. lst, by reference to which latter, and to Fig. 13, it will be seen that the mouth 'uf'. of the channel is also formed with overlapping edges u, u, which are. continuations ot' those on the channel u, shown 1n otherwise they are carried over, controlled by the overlapping edge um, (see Fig-11) to the dellector nl", by which they are shunted back into the mouth r4, of the hopper to be returned thereby to the rotatable section V.

The eyelets are supported in the channel u, until required for use, by the cheek or escapement lever u?, which isof 'the rock lever class, pivotally supported at u8, on the channel standard U. and is formed with points u, nl", which contact alternately ivi/th the eyelets of the clips as they are checked ott' to the lower part of the channel. lVhen at rest in normal position as shown in Fig.

t), the. upper arm u" of the escapement lever messi;

While the vpoint u, intercepts the next succeeding clip and thereby again sustains the column of clips above. The released clip descends from theescapement to a seat u, at the bottom of the channel u. This seat um, may be formed directly in the channel standard U, or `may be formed of a separate piece u, to be attached rigidly thereto, as may be found most expedient. The seat als, positions the clip withits eyelet in alinement with thecentralizing pin r4, of the eyelet-riveting punch R. The eyelet is held in position on the seat u, bythe front edges of the gates u, which overlap the eyelet flange and prevent the clip from ldi'splaccmlfnt until forwarded by the riveting piinch as hereinbefore fully set forth, under the action of which punch the gates yield, being closed normally by springen, @L12-'said gates u, u, being of course pivotally attached to the lower end of the channel standard U, as at u, al?. The gates u1, a5, are also provided with r'car projections or handles um, u, by which they may be manually manipulated when access is desired to the seat ula, to remove a defective clip, or to empty the channel" for any reason,-the escapement lever fu? being also in like manner preferably provided with a handle or rojection u, by which it may be manna ly manipulated for the latter purpose.

To provide for this manual, manipula-tion of the escapement a7, when desired, and also to obviate possibility of damage by the use of rigid positive means of operation, I connect said escapement lever u7, with the cam lever D4, by means of a coiled spring u1",

attached to an extension ci, on said cam lever D4, and to the upper arm u, of the escapement lever u?, as indicated in Fig. 10.

Thus when the cam lever D4, is in its raised normal position as shown in solid lines in said figure the spring u1", holds the escapenient lever M7, with its upper arm u, against the channel standard U, as in Fig.

I. 9, and' when it is lowere las in dotted lines in Fig. 9, it depressest e said escapeinent lever a7, onto the position .shown in Fig. 31, iwithits arm w12 in contact with the channel standard. This elastic resilient connection `between the escapment and its actuating cam lever'is amply sufiicient to operate the escapement without danger to the delicate clips, while admitting also of the manipulation of the escapement by hand when desirable, as is frequently the case in the operation of the machine on account of thi' presence of defective clips in the channe In this connection it may be stated that the channel standard U, is so positioned with)ela,tion to thevoperator, that the clips in the channel u, are always exposed-conveniently within the lineof vision of said voperator so that defectiveclips may be re` moved, or other precautions taken to prevent damage or delay. This is an important practical advantage. in the operation of the machine in order to attain the best results therewith.

The operative use of' the apparatus is as follows:

The eyelet riveting punch mechanism having been adjusted to a position iii `front of the hole punching and patching mechanism at which the axial distance between the two mechanisms is equal to the proper requisite distance between the eyelet clip applied to the body of theV envelop and the reinforced prong hole formedfoi' the reception of its prongs on' the flap thereof, and the Work table W, in a. horizontal position, having been vertically adjusted to accommodate the width of the envelop, the treadle is then depressed to releasel the clutch sleeve on the cam shaft, allowing it to engage with the power pulley to rot-ate the cam shaft. The treadle being immediately released, the cani shaft will make one revolution and then again come to rest for reasons hereinbefore set forth. During this revolution of the -cam shaft a cycle of actions by the several -channel, and forced its eyelet through the Opposed portion of the envelop body andV against the upsetting die, which turns over and clenches the edges of the eyelet. After the punching of the prong hole in the flap and patches as above stated the patch and` print dies and the hole punch retire, when the forwarding cam raises its lever and with it the pawl which rotates the ratchet connected with the strip feed rolls thereby drawingthe patch strips into position for the next reciprocation of the patch dies and punch. As the forwarding cam lever is allowed to resume its normal position during the completion of rotation of the said cam, said lever by its connection with the escapement lever on the clip feed channel rocks said escapement so as to check off and releasethe next succeeding cig/ip in the channel and allowit to descend intiiposition for the next operative stroke of theeyelet-riveting punch;

A. V,through the :connection with a cam-actuated lever, and

The machine being now again at rest at the completion of this single revolution of the cam shaft, since the vclutch sleeve has automatically detached itself from the power pulley, and the detent lever has again engaged with its notch or depression in the strip forwarding cam (or in fact ras soon as. thev retractile stroke of the dies, and punches .has begun) the operation of the apparatus may be conducted continuously though intermittently, in that the treadle may be depressed practically as fast as a completed envelop can be withdrawn and another substituted.

Incidentally it may be noted that by my special clip eyelet riveting means the eyelet is made topenetrate through the envelop bodywithout previous or preparatory puncture thereof, a saving of what has heretofore constituted a separate operation.

What I claim as my invention and desire to secure by Letters Patent, is:
