.To all whom t may concern,.-

Beit known that I, AINSLIE W. FERREs, of Memphis, Tennessee, have invented certain new and useful Improvements in Veneer-Dish Machines, of which the following is a speciication.

This invention relates to a machine for forming articles, such as butter-dishes, from Veneer; and the machine .is so constructed 1o and organized as to feed forward a strip of veneer of wood or other suitable material from a roll and to pass the same beneath a reciprocating cutter-die, whereby dish-blanks are cut and scored, the blanks being then moved i 5 forward singly beneath a forming mechanism, whereby the edges of the blank are folded, the side and end portions overlapping at the corner and iinally the overlapping portions secured by staples which are made and set zo by mechanism operating in due order and relation to the blank-cutting and dish-forming mechanism.

My invention is illustrated in the accompanying drawings, in which- 2 5 Figure l is a perspective view showing a roll of veneer on the feed side of the machine and a traveling belt on the delivery side thereof. Fig. 2 is also a perspective View, but taken from the feed side of the machine.

3o Fig. 3 is a side elevation with parts omitted and intended, mainly, to show the drivingshaft and gearing connected therewith. Fig. 4 is a sectional elevation with parts omitted, also intended to show the arrangement of the gears between the sides of the frame. Fig. 5 is an inverted plan of the cutter-die. Fig. G is a detail showing in sectional elevation the upper former and its spring-supports and in due relation thereto parts of the stapling 4oA mechanism. Fig. 7 is a detail of apart of a feed mechanism for advancing the staplewire. Fig. Sis a detail showing a broken section of the movable member of the former and showing a clenching-anvil secured in a recess thereof. Fig. 9 shows the blank, and Fig. lO the completed article.

The mechanism comprises in the preferred construction a spindle on which the material, say a strip of wood veneer, is rolled and from 5o which itis unwound or paid out, means for feeding forward intermittently the strip of veneer, a blank-cutting mechanism comprising a reciprocating die having cutting and scoring knives, a former comprising coacting dies by which the blank is bent into the re- 5 5 quired shape, mechanism for feeding staplewires and for forming and driving the staples to hold the overlapped portions of the dish, and a means for discharging or clearing the completed dishes from the machine and de- 6o livering them upon a conveyer. The principal part of this mechanism is supported upon a skeleton 'framework 1l, in which is `provided bearings for a main driving-shaft 12, its driving-pulley and belt being clearly shown in Fig. 1. This main shaft has thereon a spur-gear 13, which imparts motion through a large intermeshing gear 14 to a countershaft 15. Said gear 14 has a wrist-pin 16, to y which a pitman 17 is connected, said pitman 7o being connected at its upper end to one end of a cross-head 18. This cross-head reciprocates between adjustable guide-plates 18, having angular arms 18h, which are slotted for the passage of threaded studs 18c and con- 75 iined between the adjusting-nuts 18d. By turning the latter the guide-plates may be lowered, so as to secure the cross-head in desired position, and being wedge-shaped the plates may also be made to compensate for 8o wear.

The shaft 15 has upon its opposite end a crank-disk 19 with a wrist-pin and pitman marked 16 17, respectively, the latter being connected at its upper end to the opposite end of the cross-head. Said cross-head carries upon its lower surface a series of knives for cutting and scoring the blank, and the arrangement and form of these knives are shown in Fig. 5.y 9o

20 represents the cutting-off knife,whereby the strip of veneer is severed into blanks of the required length. The dishes are of flat oval form with rounded corners. The cutting-die preferably has the corner-knives 21, 9 5 by which the corners of the blank are cut. The die carries also the scoring-knives 22 and the slitting-knives 23.

The dish-blank is shown in Fig. 9, and the cuts and scores corresponding to these sev- :oo eral knives are therein indicated lby the heavy lines of the drawings.

The material, in the form of a long strip of veneer, is wound into a roll 24 and placed on the spindle, as 25, which spindle is provided with a sheave 20, adapted to be driven by a belt 27, which is driven from a small pulley 2S on the main shaft l2. Said belt is intended to run loosely, so as not to turn the spindle 25 unless tightened by the attendant. This is done by the belt-tightening device shown in the drawings, Fig. and comprising the rock-shaft 29, having the arms 3l, the former being provided with a pulley 32 to impinge the belt and the other, with the weight 33, normally tending to hold the pulley out of contact. The shaft 29 has the lever 34, by which the attendant may rock the shaft and tighten the belt. This mechanism serves to unwind the strip of veneer from the roll 24, allowing it to depend loosely, so that it shall not break.

The material being conducted over the roller 35 passes between two feed-rolls, (best shown in Fig. 4 and marked 3G 37,) one of the feed-roll shafts being driven by the link belt 3S, deriving its power from a sprocketgear 39 on the shaft 15. The belt 3S passes over sprockets 40 4l, the former being mounted on the shaft 42 and the latter on a shaft 43, hereinafter designated as the cam-shaft. Shaft 42 is mounted in adjustable bearings in order to take up wear and to adjust the gearing. The shaft 42 and the shaft of the feed-wheel 3G each carries a mutilated gear, said gears being marked 44 45. The gear 44 has only a portion of its periphery provided with teeth, the remainder of its rim being blank, while the gear 45 has three toot-hsections separated by intervening blanks 40. Obviously, therefore, the toothed sections of said gears being of corresponding lengtlnonc revolution of the gear 44 will produce onethird of a revolution of the gear 45, and consequently the shaft of the lower feed-roll 3G will be given an intermittent rotary movement, while the shaft 42 has a constant rotary movement, the idle periods being filled in by the manipulations upon the blank in converting it into the finished dish. The strip of veneer is fed by the frictional contact of the wheels 3G 37, and the upper feedwheel may be mounted in sliding bearing with adjustable screws 47 therefor.

In order to prevent the veneer from buckling or bending, which it would be likely to do if force were applied to the end of the blank to move it, I make use of a springshoe 4S, which rests on the sheet of veneer beneath the feed-wheel, and its rear end being bifurcated to embrace the wheel and the bifurcations extending up, as at 4S, and being secured to the cross-piece 49. The shoe is therefore under a spring-tension due to the resiliency of its material and serves to hold the sheet of veneer flat some distancein front of the feed-wheel. The shaft l2 being putin motion, at each revolution the cross-head carrying the cutting and scoring knives is caused to reciprocate, and at the end of its downward movement it severs the blank, such as shown in Fig. 9, from the continuous strip of veneer. At each such revolution a complete revolution is imparted to the shaft 42, and through the mutilated gear thereon a partial rotary movement is imparted to the feed-wheels 3G 237. Obviously, however, the lfeed-wheels remain at rest, notwithstanding` the constant rotation of the shaft 42, while the blank portion 4G is in contact with the non-toothed portion of the periphery of the gear 44, and therefore time is allowed for the descent of the die and the cutting off of the blank. The blanks follow each other successively, each one pushing those in front of it onward to ward the forming-dies. The latter are best shown in Figs. 4 and 5. 50 represents an upper chambered die of approximately the same shape in cross-section as the completed dish. This die is mounted so as to have a slightvertical yield, this being accomplished by providing it with stems 5l, which pass through the axes of coiled springs 52, arranged between the arms 53 of the bracket 54. The stems 5l have collars 5l pinned thereto, and the lower ends of the springs rest on said collars. A slight clearance is allowed between the lower bracket-arms and the upper surface of the die to permit the vertical movement of the die against the tension of the springs. This die is transversely apertured and'is provided with spring-yokes 55 5G, the prongs of the yoke 55 serving to engage the blank and hold it upon the lower or reciproeatin g die and the prongs of the yoke 56 serving to tuck in the end flaps of the blank. The lower or plunger die is marked 57. It has a stem 5S provided with a roller 59, which travels in the groove G0 of the cam-disk Gl, mounted on the camshaft 43. The cam-shaft is driven by the spur-gears G2 G3, the former being' mounted on counter-shaft 15. Obviously, therefore, an intermittent vertical reciprocatory movement is imparted to the lower or plunger die. The plunger-die 57 is provided with vertical slots G4, and stripperfingers (55, carried upon a bar G6, project diagonally through said slots. (See Figs. 1 and 4.) As the die recedcs with the finished dish these fingers act to strip the dish from the lower die, and being inclined rearwardly drop it upon the belt conveyer G7, by which the dish is carried off.

The staple-forming mechanism may be of any usual or desired type, the only features of novelty in reference to such staple-forming mechanism herein claimed being the gearing by which it is driven.

The cam-shaft 43 has on its extremities the grooved cams G8, which through the instrumentality of the rollers 09, carried on studs 70, secured with the reciprocating pitmen 7l, operate the staple-forming mechanism. The

Two forms IIO of gearing are shown. In Fig. l the upper end of the pitman is square and has a reduced portion, over which is slipped a sliding sleeve 7 2, provided with a rack 7 3 on one face thereof. This sliding rack-sleeve is seated upon a spring 7a and is confined by the nuts 75. The rack engages a spur-gear 76, which in turn is enmeshed with a rack 77 on sliding plunger 7 8, said plunger being taken as representative of the staple-forming mechanism. The preferred construction, however, of the gear connection between the plunger and the pitman is shown in Fig. 6, `wherein the upper end of the pitman has its reduced portion round instead of angular and carries a sliding sleeve 79, having ribs 79, which are engaged by the gear-teeth S0 of an irregular gear 8l. Said gear 8l has also the gear-teeth 82 working in the rack 77 on the plunger 78. The object of constructing the gear 8l in the peculiar form shown is to secure a long stroke of the plunger 78 with a short stroke of the pitman 7l. The interposition of the spring 7 a and the employment of a yielding toothed sleeveprovides for any inaccuracies of adjustment and prevents injury to the gearteeth.

The wire for forming the staples is carried upon spools, one of which is shown in Fig. l at S3, and the spindle for the other spool is marked S4. The wires are led off through the tubes S5 and pass between pairs of feedwheels 86 S7, mounted on shafts 88 89. The shaft S9 has a ratchet-wheel 90, which is engaged by a pawl 91, carried upon the upper end of a pivoted lever 92, the pivot of the lever being shown at 93. The lower end of said lever is slotted, as at 94, and a pin 95 works in said slot and carries an antifriction-roller 96, which works in the cam-groove of one of the cams GS. The rotation of said cam will therefore effect the vibration of the lever 92 on its pivot and the feeding step by step of the wire.

The wire is fed to the staple-forming mechanism at the point indicated at 97, Fig. 6, and the action of the parts is such that upon the completion of the formation of a dish by the dies the staple-forming mechanism is actu ated and staples 98 are driveninto the overlapped flaps of the trays or dishes. The staples are of the usual U shape, and in order to bend their prongs uniformly I employ an anvil, which is shown in detail in Fig. 8. Said anvils are mounted in grooves 99 in the lower die 57, as shown in Fig. 6. The anvil is marked 100 and has scores in its face intended to receive the ends of the stapleprongs and direct them toward each other, preventing their bending to one side. These anvil-blocks are removably held in the groove by a set-screw or in any other convenient manner.

I claiml. In a machine of the class described, a dishforming mechanism comprising a recessed die and a plunger-die, said plunger-die being provided with vertical slots in its substance and bent arms projected into said slots and adapted to strip the dish from the die as the latter recedes with the nished dish, substantially as described.

combination with a blank cutting and forming mechanism, of stapling mechanism having reciprocating plun gers and gearing for reciprocating said plungers comprising a pitman for each plunger, a toothed sleeve slidably mounted on said pitman, a rack on the plunger and a gear interposed between the toothed sleeve and the rack, said sleeve being spring-supported and said gear having tooth-sections of diiferent radii, substantially as and for the purposes described.

4. In a machine of the class described, the combination with blank-cutting and dishforming mechanism, of a stapling mechanism lembodyin g reciprocating plun gers, pitmen and interposed gearing for reciprocating said plungers, cams for imparting movement to said pitmen, and a staple-wire-feeding mechanism comprising a pivoted lever operated by one of the pitmen-cams, a pawl actuated by said lever and wire-feeding mechanism intermittently actuated by the pawl, substantially as described.
