MACHINE FOR MAKING VENEER DISHES.

SPECIFICATION forming part of Letters Patent No. 364,404, dated June 7, 1887.

Application filed Septcml or 17, 1884. Serial No. 143,273. (No model.)

To all whom it 11mg concern.-

and clinching a wire staple or fastener at each end thereof to confine and bind together the upturned flaps which constitute the ends of said dish, as well as devices for feeding to the machine the veneer-blanks and discharging the finished dish therefrom.

The machine embodying my improvements is shown in the accompanying drawings, wherein-- Figure 1 gives an elevation of thatside of my machine from which the product is discharged. In this view a part of the feeding apparatus and a portion of the under forming die are not shown in order to bring into view more clearly parts immediately in theirrear. Fig. 2 is a view, partly in elevation and partly in transverse vertical section, on line 1 2 3 of Fig. 1, of my machine. Fig. 3 is a side elevation of sprocket-wheel, pawl and ratchet, and rack and pinion for operating feeding apparatus. Fig. 4 is an edge view of same. Fig. 5 is a top or plan view of the devices for bending down or clinching the wire staples which fasten the folded flaps constituting the end ofthe dish. Fig.7 6 is a longitudinal vertical section taken through the center of the stapleforming dies. Figs. 7, 8, and 9 are views of different positions of the dies orslides in process of forming and. driving a staple. Fig. 10 shows a veneer-blank for a dish before same has been folded. Fig. 11 is a view of a finisheddish. Fig. 12 is a view of the endfolders, showing their relative positions in regard to the folding-bed and to the dish.

The machine may be resolved into the following groups of mechanism--viz:

First. Devices for feeding the dish-blanks to the machine and discharging the finished product therefrom, the same apparatus being employed for both purposes.

I Second. Mechanism for folding the veneer or other dish blank and holding same while the fastening-staple is being driven.

Third. Apparatus for feeding to the stapleforming machinery the wire from which the staples are made. Inasmuch as any wellknown method 'or apparatus for doing this part of the work may be employed in this machine, I have not shown the same, it beingunderstood,without further explanation, that anysuch suitable apparatus may be employed therewith.

Fourth. The staple forming and driving devices, which are consolidated.

Fifth. Devices for clinching or bending down the prongs of the staples after they are driven.

Sixth. The driving mechanism for operatin g these several parts.

The mechanism is all mounted in or on the frame A and receives its motion from main driving-shaft B, upon which the driving-pulley A and friction-cone O are mounted. Pinion N drives gear 0 on shaft 1?. On shaft 1? is placed the crank-disk O, which carries the pin a and cylinder Q, upon the surface of which the friction-rolls c a and (l dare piv' oted. Said friction-rolls impart an intermittentsemi-rotary reciprocating motion to shafts ff by alternately engaging lugs e e on opposite sides, whereby the clinching-disks g g at top ends of shafts f f are brought to bear on the prongs of the inserted staple and bend them down. i

The crank-pin 2' on disk 0 works in atransverse slot or way, D, on the vertical slide-rod E. In Fig. 1 of the drawings I have shown only the central and right-hand portions of my machine; but both sides are alike in construction, there being two sets of staple-forming devices and two slide-rods E. Each of the slide-rods is provided with a section of rack It, which engages with a sectoral gear, S, having a radial arm, S, which connects with and actuates the pitman T, whereby the staple forming and driving devices are operated. A cross-head, F, is attached to the upper ends of slide-rods E, and to this cross-head is attached the plunger WV, which engages Withand actuates the staplc-wiresevering punch X. It is also provided with the bridge G, which, together with cross-head F, affords guideways for the drive-rods I I. To the the dish the advancing lower ends of said rods I I are attached the two folding devices or shapers L and M. These folders act in conjunction with the sectional folding-beds D D, which are bolted to girt E of the frame of the machine.

I will now describe the independent action of each group of operative devices without reference to the concurrent action of any other group, taking up the feeding apparatus first. This; consists of two sprocket-wheels, K K, disposed one on each side of the machine. Over the sprocket-wheels runs the chain L, which at regular intervals is equipped with feeding-fingers N N. Motion is imparted to the sprocket-wheels by means of a rack, E, and pinion F on the sprocket-shaft G, Figs. 3 and 4. Gear F and ratchet H are rigidly attached to shaft G, and pawl J, pivoted on an arm of the sprocket-wheel, engages with ratchet H. The sprocket-wheel runs loosely in one direction on shaft G. Rack E is attached to a bracket-arm, D, projecting from cross-head F, and takes a corresponding vertieal reciprocating movement therefrom. The motion of cross-head F through the connections above described imparts an intermittent progressive motion to the feed-chain, in the direction of the arrow, of about the breadth of one dish-blank, or of the interval between two adjacent feed-fingers, N N. The blanks are fed to the machine by laying them on plat form 0 just behind and against the finger carrying in the last blank and in position for the next following finger to catch it and carry it forward under the folding-die M. The chain remains stationary while the dish is shaped, and when the upward movement of the cross-head carries the folder M up clear of finger N forces the dish off from the form D onto the table 1?, or onto any receptacle provided therefor, at the same time the following finger N carries a fresh dish-blank into position between the folding-dies, to be manipulated as above described' The mechanism for folding the blank and shaping the dish consists of a bottom die or folding-bed divided into two parts or halves, so as to leave a clear and unobstructed interval between them for the passage of the feedchain. These sectional beds are shown at D D, and are bolted permanently to some part of the frame of the machine. Their tops are made to conform to the interiorshape of the end of the completed dish. Together they constitute the male member, as it were, of a pair of dies, of which the folding-die M is the female member. Die M has two drive-rods attached to its upper side, which pass up through guideways or hearings in the crosshead. For the sake of clearer discrimination, I have termed the die M the ,side-folder, and that portion of the apparatus which bends down the central end fold (shown at L) the or way constructed in top of slide R.

end-folder. I Drive-rods I I pass through and freely play in apertures in end-folder L. Folder L has a tongue at each end bent down to an angle to conform to the shape of the finished dish, and alsohas two steady-pins, Z) I), attached to its under side, which pass through folder M, so as to bear on the dishblank. The bottom ends of the lips of the end-folderare slightly longer than the steadypins, so as to permit the central flap of the dish-blank to be first broken down or bent over the forming-bed and seatitselfin its true position to be bent before the steady-pins strikeit and confineitto theforming-bed. The side-folder M does the duty of bending down the portions of the blank which form the sides of the dish 19 2, Fig. 10, and also the cornerseetions a n n a, which overlap the center flaps, 0 0, in the finished dish. These offices are accomplished, respectively, by the side folding-lips, Z2, and the cornerlips,7c7c, Fig. 12.

To regulate the co operative action of the two folders L and M, the drive-rods I I are equipped with collars a c, nuts J J ,and springs H H and K K. The springs H H, interposed between collars a a and bridge G, act to force the rods I I down until their further descent is arrested by the stop-nuts J J. Thesprings K K, interposed between the under side of cross-head F and the upper side of folder L, act to force folder L down until it rests 011 the top of the bosses r r of folder M. The action of these springs is such that when the cross head F is elevated to its greatest limit the lips jj will be depressed, so that their lowest extremities will be first to engage the dish-blank by striking the center flaps, 0 0, of the blank when the descending movement commences.

The wire for forming the fastening-staples is supplied to the staple-forming dies by any convenient or suitable feeding device through the orifice s, Fig. 1. The staple-forming dies consist, mainly, of two horizontal plates or slides, both of which have an endwise movement in the direction of the driving of the staple. They are arranged to slide one on top of the other, and are mounted in pairs, one on either side of the machine, on a suitable table, Q. The details of these slides are shown in Figs. 6, 7, -8, and 9, and their driving-connections in Fig. 1. The case in which the slides work consists of a bed-piece, and a cappiece, Y. These are fastened together, and also to table Q, of the machine. Between the two plates are fitted the two slides It and S. Slide S is fitted to work in a longitudinal seat Top slide, S, receives a positive reciprocating movement through pitman T, Fig. 1, from the arm S of the sectoral lever S, which is pivoted on the bracket Y and takes its movement from the slide-rod E through the rack and segment R S. The slide R has a subsidiary movement imparted to it from pitmanT, through the impact of the shoulders a a at the outer end thereof, against washers or collars a or t, which areloosely fitted on pitman U. Between ICC lIO

tion that the pin 1) is pressed against by the washer t in the downward movement of the pitman T and the pin b is pressed against by the washer a in the upward movement of the pitman.

To the front end of slide S is hinged thelip V, which has a transverse upturned ledge, 10,

at its outer end. When slide S is thrown forward or inwardly a sufficient distance, lip V will drop down, as seen in Fig. 6, and when it is retracted lip V will impinge against the beveled end 0 of bedplate Q, and thereby be forced into a horizontal position, as seen in Figs. 7 and S.

Then lip V is dropped, as seen in Fig. 6, itleaves the hingechucks d d projecting, as

well as the central part, c, of slide S, so that such projecting sections (1 d and 6 form the hammer or driver for forcing the prongs of the staple through the folded flaps of the end of the dish when the parts are in the position seenin Fig. 1.

Thestaple is formed by first passing the wire through guide 8 under cutter X, Fig. 1,(which cutter works in die X, Fig. 9,) and cutting off a proper length thereof to form a staple. This blank y then drops through hopper T down onto and athwart the lip V.in position, as in Fig. 7, between ledge w and tongues cc. In the back-stroke of the slides the movementof the slide It is arrested or retarded by its rear endimpinging againstalug or abutment, afleast on bed-piece Q,before slide S has reached the limit of its stroke, thus causing lip V to be still further retracted between tongues c c, and thereby causing blank 1 to be caught between ledge 10 and tongues c c and the ends thereof to be bent around so as to lie in creases a: as,

being bent into the form shown in Fig. 8.-

After being so bent the sliding movement is reversed, and the slide S, advancing ahead of slide R, permits lip V to fall down or drop into a dependent perpendicular position out of the way of striking against the side of the former-bed D, as in Fig. 1. The slide S is caused to advance ahead of the slide R, inasmuch as the spring V has to be compressed by the shoulder a on pitman T striking the collar a before the slide R can be moved. The completed staple then is held by its prongs in creases x a of the tongues c c, with the driving end of slide S following closely in its rear. Slide 1% advances until the tongues c c strike against the end of the dish, when its movement is arrested; but slide S still advanees and forces the prongs of the staple through the folded flaps of the end of the dish and into the position seen in Fig. 5, ready to be bent down or clinched.

The clinching devices are shown in elevation in Fig. 1 and in plan in Fig. 5. They consist of four vertical shafts arranged in pairs, one pair for each half ,of the forming-bed. These shafts are shown at f f and are supported in suitable bearings. One of each pair has a tappet-1n g,e, at its bottom end, whichis acted upon by the frietiourolls c c and d d on drum Q,

the leading set 0 c acting against one wing of the tappet-lug to rotate the clinching-heads g g in one direction and the trailing set dd acting against the opposite wing of said tap- 3et-lug to effect a reversal of said clinchingheads. The construction and operation of said clinching-heads may be deduced from Fig. 5. The headsg ghave each a portion oftheir periphery cut away,so as to leave a shoulder, 7t 7t. These shoulders are shown in repose, or in position to be acted on by the advance of leading friction rolls 0 c. As cylinder Q'rotates, it first brings rolls 0 0 into engagement with tappet-lug 6, thereby causing a partial rotation of the clinching-heads against the prongs of the-staple as they protrude through the apertures in the side of the formingbed D, and bends them down toward each other on the inside of the dish. This being accomplished, the trailing friction-rolls d 01 come up, and, impinging against the opposite side of tappetlug e, rot-ate the clinching-heads in the oppo site direction and restore them to their first position, ready to act upon! the next staple to be driven.

The operation of the machine is as follows: Oross head F being elevated,a blank is laid on the feeding-table and the machine started. The feed-chain carries the blank between the foldingdies, and the further descent of the cross-head carries folder L down to a point where the extremities of folding-tongues 7' j bend down center flaps, o 0, of the blank, and at this point steady-pins b 1) pin the blank firmly down and arrest further descent of folder L. Pending this, plunger \V, acting on punch X, has severed a staple-blank from the feed-wire and the same has dropped into ho y per T preparatory to formation into a staple by the back-stroke of the staple-forming slides. Further descent of crosshead F carries holder M down to its work, and the sidespp and corner flaps n a n a are folded down into posit-i011. At this stage the slides S and R carry staple y up into position to be driven through the folded end flaps of the dish at either end of the folding-bed D D, and further advance of slide S drives the staple prongs through the overlapped flaps, as shown inFig. 5. This being accomplished,the clinching of the prongs under the action of the clinching disks or gears g g, controlled by friction-rolls c c and d d, follows, as hereinbefore described. This completes the formation of the dish, when the up stroke of the crosshead and slide-rods E effects the discharge of the dish by the movement of chain L, at the same time, through the back-throw of the sectoral arm S, causing a reversed movement of slides R and S,whereby the last staple-blank cut off is, through the IIO co-opcrative action of said slides, formed into a staple, as before stated.

Hence I claim 1. In a machine for making a folded dish of 5 the kind described, a forming-bed consisting of two semi-sections having an open Way between them, as a provision for facilitating the delivery of the dislrblank to the folding-dies and the discharge of the folded or finished dish to from the machine, substantially as specified.

2. The described member of the staple-forming device which performs the duplex function of bending the prongs of the staple in its back-stroke and of driving the staple in its 15 direct or forward stroke, consisting of slide S, having hinged lip V, with ledge 10, all constructed and arranged to opelate substantially in the manner. described, and for the purposes set forth.

:0 3. The combination of the stationary forming bed divided, as shown, with the endless chain feeding device having an intermitt-en movement, substantially as described.

4. The combination of slides R and S, with 25 the spring V interposed between them, sub

stantially as shown, and collars u and t, connected with slide R, and shoulders a" and a, connected with slide S, substantially as specified.

5. The combination of end-folder L, hav- 3o ing tongues T, and pins 22 b, with the divided folding-bed, substantially as described and set forth.

6. The combination of slide R, having elevated lateral ledges and driving-channelsm x, 3 5 with driving-slide S, provided with the hinged lip V, in the manner described, and for the purposes specified.

7. The combination ofdrum Q, carrying tappet-wheels c c and d d, with the shaftsff, car- 0 ryi ng tappet-lugs e e, and clinching-heads gg, recessed to form the shoulders 11., and for the purposes set forth.

In testimony whereof I have hereunto subscribed my name, at Richford, Vermont, this 5 27th day of August, A. D. 1884.
