SPEGIFICATION forming part of Letters Patent No. 456,483, dated July 2 1, 1891.

Application filed March 25, 1890. Serial No.345,277. (No model.)

To all whom it may concern..-

Be it known that I, JEFFREY THOMAS FERRES, a citizen of Canada, and a resident of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Veneer-Di sh Machines, of which the following is a specification.

The object of my invention is to form dishes-such as butter-dishes-from a veneer of wood or other suitable material by feed ing a strip or roll of veneer of the same into a machine which is constructed so that the first operation of the machine is to feed a suflicient amount of veneer to form a dish which is cut into shape and scored by means of knives ready for bending into shape; second, to form die-shaping mechanism which bends up the ends and sides of the dish and laps the slitted portions, and, lastly, to secure the lapped portions by staples, which are automatically inserted and clinched while the dish is held under operation, all of which will be fully set forth in the description of the accompanying drawings, making a part of this specification, in which-- Figure 1 is a plan of a blank shaped and scored ready for forming into a dish. Fig. 2 is a top plan View of the machine, the crosshead and part of the feeding mechanism be i ng removed. Fig. 3 is aside elevation of the same. Fig. at is an enlarged detail View, partly in section, of the feed mechanism. Fig. 5 is a top plan View of the same. Fig. 6 is a detail representing the lower die in end elevation. Fig. 7 is a section of the same through line .rx, Fig. 0. Fig. 8 is a view similar to Fig. 7, showing the manner of folding in the ends of the dish. Fig. 9 is an end view of a completed dish. Fig. 10 is a detail view, partly in section, showing the stapling mechanism in side elevation. Figs. 11,12, and 13 aredetail views showing the successive movements of the stapling mechanism. Fig. 14 is a perspective View of the staple forming and driving slides. Figs. 15, 16, and 17 are sectional views on line y y, Fig. 18, corresponding, respectively, to Figs. 11, 12, and 13, and showing the manner of forming and driving the staples. Fig. 18 is an end view of the stapling mechanism. Fig. 19 is an end elevation of the male die. Fig. 20 is a side elevation of the same. Fig. 21 is a section on line o o of Fig. 20. Figs. 22 and are elevations of parts shown in Figs. 19 and 20. Figs. 24 and 25 are details of the wire-feeding mechanism. Fig. 26 is a view illustrating the extent of circumference given to the

rolls

9 and 10, with relation to the surface of the blanks to be acted on, the width of the blanks being designated by the letters but in Figs. 2 and 3 no attempt is made to show the veneer blanks in their proper relative proportions with reference to the rolls.

1 represents the main frame, on which the various parts are separately secured in secondary framesi.

3 represents the driving-shaft, which is jou rnaled in opposite sides of the main frame. Motion is communicated from the drivingshat't to the shaft 4. by means of spur-gear, as indicated in dotted lines.

5 represents a cross-head, supported 011 upright guides a and actuated through connecting-rods a by crank-wheel A on shaft 4.

(3 represents a table, over which the veneer fed to the machine from the roll 7, the table 6 being provided with adjustable guides S on its opposite sides. The veneer is fed to the machine by means of

rolls

9 and 10, which are located one above and the other below the veneer.

11 represents a vibratory tongue or knifeclearer, which is mounted on trunnions b and held normally in the raised position by a spring Z), attached to its outer end. As the veneer passes through the feed-rollers it is fed onto the vibrating tongue, which holds it suspended above the scoring-knives 12, the veneer being held firmly against tongue 11 by means of spring-arm 13, which is bifurcated to pass on the opposite sides of the feed'roller 9, and is adj ustably secured to the shaft 14 behind the feed-roller.

Motion is communicated intermittently to the lower feed-roll 10 by means of the mutilated gears 15 and 16, the gear 1b being operated by a chain-belt N from the shaft 4, as indicated in Figs. 2 and 17 represents an ordinary belttightener.

The feed-rolls will make one'third of a revo' lution to each revolution of the gear 16, thereby suspending the feed during the operation of scoring and forming the dish. After the veneer has been fed over the scoring-knives the cross-head 5 descends, bringing the press 18 down onto the veneer, forcing the vibrating tongue 11 into the position shown in dotted lines, Fig. 4, bringing the veneer onto the scoring-knives 12, forming the blank represented in Fig. 1. As the cross-head rises, the tongue 11 is raised by the spring I) forcing the veneer off from the scoring-knives and raising it sufficiently so as to pass over the shearing-blade 57 at the next operation of the feed. When the feed again operates, the blank previously formed is fed onto the top of the lower forming-die 19, while a new length of veneer is brought over the scoring-knives. The lower forming-die, as seen in Fig. 2, consists-of a shallow cup 20, the contour of which determines the form of the dish. It is slotted to receive the upwardly-projecting ends of the yoke 21 and also at the ends to receive the folding-fingers 22. It is also recessed at the ends to admit the ends of the stapling devices. The upper die consists of the head 24, which is the counterpart of the lower die, mounted on the rods 25, which pass up through bracket 26, which is secured to the cross-head 5. The rods 25 are limited in their down ward motion by nuts above the brackets 26. They are also held to the work by means of the springs 27 and pins passing through the rods below the springs. In the center of the upper die between the rods 25 is mounteda spindle 28, having lugs 29, restingin grooves in the top of the die-plate.

30 represents the four clinching-levers. They are pivoted to the die-plate, as shown in Fig. 21, with the inner ends resting between the spindle 2S and its lugs 29, while the other ends pass through the slots in the ends of the die-plate and rest against the dish when the dies are closed.

Theelinching-levers are operated by means of the lever 31 pivoted in lugs 99 projecting from the upper side of the die-plate, the inner end of said lever resting in an annular groove at the upper end of the spindle 28, while its opposite end projects out over the end of rod 58, by which it is actuated at the proper time.

32 represents a spring to hold the lever 31 normally-in the raised position. As the outer end of the lever 31 is forced up, theinner end forces the spindle 28 down. The conical por tion being forced down between the inner ends of the clinching-levers 30 forces them out and bringing the opposite ends together clinches the staples which have previously been driven through over the inner side of the dish.

Figs. 10 to 18, inclusive, represent the stapleforming mechanism, Fig. 10 representing the dies closed upon a dish and the stapling device ready for operation.

Figs: 11, 12, 13, 15, 16,and 17 represent the difierent steps in the process of forming and driving the staples. The wire is fed to the stapling device intermittently by feed-

rollers

36 and 37, as represented in Figs. 24 and 25, the feed-rolls being partially rotated at regular intervals by means of a ratchet 33 and pawl 34, the extended shank of the pawl resting on a cam secured to shaft 35.

Figs. 11 and 15 represent the relative positions of the staple former and driver in their boxing as the wire is fed in, 0 representing the wire, which is fed through a hardened steel plug screwed into the side of the stapleboxing. The staple-former 38, Fig. 14, which moves backward and forward in grooves c in the sides of the boxing, now moves forward, shearing the wire ofi against the end of the hardened plug, and continuing its forward motion bends the ends of the wire around the corners of the steel templet B. The templet B is held in'place by screws, Fig. 18, and is thus detachable and reversible, so thatwhen its corners become worn by bending the wire around them the templet can .be turned with its other side to the work ends of the staple resting in grooves in the sides of the former, as illustrated 'in Figs. 12' and 16. The former continues its forward movement until its ends are pressedagainst the dish,

which is firmly clamped between the dies.

During the-preceding operations the templet B has been held in the path of the staple by a lug 40, extending from the upper side of the staple-driver 39. The driver now moves forward, releasing the plate B, the wedge-shaped forward end of the driver forcing it out of the path of the staple. forced forward by the driver 39 and its ends driven through the overlapping portions of the dish and into the slots in the endsof-the upper die, there to be operated upon in turn by the clinching-levers 30, while the stapler assumes its first position preparatory to forming another staple.

The staple-former and driver are actuated through connecting-

rods

41 and 42 .by'means of bell-cranks43 and 44, which are pivoted to the lug d, projecting from the main frame-,-

and are operated by pins traveling in camgrooves on rollers 45. The shaft on which the rollers 45 are mounted receives motion through shaft 4 by means of a spur-gear, as indicated in Fig. 3.

40 represents a blast-tube which is forked at its lower end to pass on opposite sides of the feed-roller 9, as shown in Figs. 4 and 5.

47 represents a branch pipe connecting with the opening 48 between the scoringknives, the purpose of these pipes being to carryblast to the machine to keep it'free from chips and dirt, and also to throw the finis'hed'dishes out of the machine. The blast coming through the opening 48 is deflected by means of a cupshaped lug on the under side of the vibrating tongue 11.

The yoke 21 is held in place by means of the bifurcated lever 50, pivoted on shaft 51, beingheld in positionbymeans ofa spring connected to the lower portion of the mainframe of the machine. 52 representsasimilarlever The staple is then.

which supports the fingers 22. The roller 7, which supplies veneer to the machine, is re tated by means of the belt 53, which passes from the driving-shaft over a pulley at one end of the roll '7.

54c represents a belttightener operating from the opposite side of the machine by le-' ver 55, which enables the operator to unwind at frequent intervals a sufficient quantity of veneer for immediate use without passing back to the veneer-roll, the veneer not being strong enough to permit moving it from the roll by means ofthe

feed

9 and 10.

19 represents Wire drums, which are inounted on brackets secured to the front of the machine.

The operation of my device is as follows: A sufficient quantity of veneer is unwound to reach the feed-roll and leave two or three yards of slack hanging over the end of the table 0. The machine is then started, when the feed-rolls feed forward on the vibrating tongue 11 a sufficient quantity to form a blank. The cross-head then descends, forcing the tongue 11 down between the scoringknives forming and scoring a blank-that is, trimming the corners with the V-shaped knives e, slitting the ends with knives f, and scoring or cutting the veneer partially through by knives 12, as indicated in dotted lines, Fig. 1, to facilitate the bending of the blank in the dies, and as the cross-head rises again the tongue 11 is forced up by the spring at its opposite end and the veneer again fed forward, bringing the blank that has already been formed above the lower die 20, the veneer resting on the ends of the yoke 21. As the cross-head descends again, the veneer is first caught between the upper die 24 and the ends of the yoke 21., holding it firmly in position while the blank is cut loose from the roll by the shear-blades 56 and 57. As the upper die descends fart-her, the yoke 21 is forced down until the lugs 22 strike the center lap at the ends of the blanks and force it up against the end of the upper die, as indicated inFig. 8, thus permitting the side laps of the blank to fold beneath the cent-er lap. The fingers 22 are 110w also forced down and the dish tightly compressed between the two dies. The stapling device then operates and the staple is formed and driven through the ends of the dish. The ends of the staples are next clinched down, as previously described. The outer end of the lever Sl is raised by means of the rod 58, which is mounted vertically in lugs on the outside of the frame 2. As the cross-head descends, the end of the lever rests on the top of the rod 58, and as the crank-wheel A revolves the roller 60, mounted in its periphery, strikes the lever 61, lifting its outer end and raising the rod 58, thereby actuating the clinching-levers 30. As the cross-head rises, the yoke 21 and fingers 22 are brought to their normal position, forcing the dish out the lower die, when the blast catches it and throws it out at the front of the machine. Should the lever 31 become clogged or refuse to act atthe extent of the upward stroke, it would be forced to the proper position by striking the lower end of the rod (32, projecting downward from the extended end of the cross-bar at the top of the cross-head guides. At the same time that this dish is being stapled another blank is being formed and scored by the press 13.
