BUTTON-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 479,704, dated July 26, 1892.

Application led October 10, 189,1. Serial No. 408,324. (No model.)

.To all whom t may concern:

Be it known that I, CHARLES E. DENTON, a citizen of the United States, residing at Attica, in the county of Harpei` and State of Kansas,

have invented certain new and useful Improvements in Button -Stapling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the ro art to which it appertains to make and use the same.

This invention relates to button-stapling machines, and has for its object the production of a machine of this class which comprises advantages in point of strength and durability, and is composed of a minimum number of parts, and which 'shall be neat in appearance, positive in its operation, and free from all complicated mechanism.

2o The invention compries novel features of construction, embracing a new and improved form of button-feed tube or chute and connection between the clincher bar or block and the cutting and bending bar or plate.

The invention further comprises an improved wire-feeding device, which is automatically operated at each formation of a staple.

The invention also comprises the detail con- 3o struction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying*drawings, Figure l is a View in side elevation of my improved stapling-machine, parts being broken away. Fig.

Fig. 5 is a detail view with parts in dott-ed lines, showing a button in place, with the wire projected through its shank. Fig. 6 is a slightly-enlarged detail View of a portion of the wire-feeding attachment. Fig.

Referring to the drawings, A designates a vertically-disposed frame or support, which is made, preferably, from one piece of metal,

and from its lower end projects a horizontal plate a, through which screws are passed for securing the same upon a stand or table. (Not shown.) In this frame is formed a chamber a', having an upper inclined top or wall a2 and a lower horizontal bottom c3. An inwardly-extending opening a4 is formed in the front portion of this frame, immediately beneath the horizontal bottom a3, and in a ver- 6o tical groove in the front end or wall is rigidly secured by a screw c5 a clinching-die a6, the upper end of which projects up into opening 0.4. The upper end of this frame is hollowed out to form a button hopper or receptacle B, and the latter is provided with a curved lid or cover b, pivotally connected at b to the upper end of the rear wall of the frame.

C is the cutting and bending bar or plate, capable of moving vertically in a groove in 7o the front wall of frame A, said bar or plate being held therein by cross-bars d, secured to the front edges of said frame. From the lower end of this bar or plate project two parallel arms d d?, in the inner opposite edges of which are grooves or recesses d3. To the arm d is secured a knife d4, the same being of right-angular formation and provided with slots d5, through which screws d6 are passed for holding said knife in place. By this con- 8o struction the knife can be adjusted to compensate for wear occasioned by sharpening.

D is the stationary knife, which is rigidly secured by screws e to the front edges of frame A, said screws being passed through slots e in said knife to permit of the adjustment of the latter. A groove or recess e2, extending longitudinally through said knife, serves as a guide for the wire X. In lieu of this groove a hole will serve the same purpose.

E is the clincher bar or block, whose Vertical side edges tit within the grooves or recesses cl3 of bar or plate C, and to this bar or block is rigidly secured an oblong link e3, the same being held by a screw e4, and at its upper end said link is loosely retained by a screw e5, projecting from bar or plate C. Thus the clincher bar or block is capable of moving upward with the cutting and bending bar or plate, and also has an additional independent loo movement, so as to permit of its depression below the cutting and bending bar or plate in the final clinching of the staple. In the lower half of this bar or block E isa vertical slotf, and in its extreme edge is an inclined groove or recess f. The upper end of baror block E is thickened to form an inwardlyextending flange e6.

Within the chamber a', resting on the horizontal bottom thereof, is a staple-former or mandrel F, the same consisting of an oblong bar fitted snugly between the walls of said chamber and having a plate f2 secured to its upper portion, from the inner end of which plate projects a lip or shoulderf3. A rigid plate f, held by screws within chamber a', serves as a guide for the mandrel, the latter moving. beneath said plate. ln the forward ends of mandrelF and its plates f2 are formed coincident slots f4, in which the button-staples are designed to tit. The extreme upper outer edge of this mandrel is also beveled or inclined to conform with thelower end of the clincher bar or block E.

G is a wheel having teeth g extending over about one half of its periphery, an d said wheel is provided with shoulders g g2, designed to engage lip or shoulder f? of the mandrel to effect the back-and-forward movement of the latter. This wheel has a third shoul- .der g3, designed to engage flange c6 of the clincher bar or block to force the latter down upon die d6 after the stapleis cut and formed and the mandrel is withdrawn. This wheel is mounted on a shaft g4, having its bearings vin the sides of frame A, and upon one end of -sald shaft is keyed a crank-wheel g5, having a segment of its periphery cut away to form two corresponding shoulders g" 97. These shoulders are designed to alternately engage a stopblock g8, adjustably secured to the side of frame A by a set-screw Q9, extended through a longitudinal slot g10 thereof. This block serves to regulate the limit of each stroke, and for this purpose is rendered adjustable. From wheel g5 projects a pin g, extended into a slot 7i in the lower end of a pitman H. This pitman at its upper end is pivotally con nected to an enlargement ZL of the bending bar or plate C. With the teeth of wheel G engages the toothed cam end t' of an operating-lever I, whose shaft ft" is projected through the sides of the frame.

J is a curved picker-arm rigidly secured to a shaft j, passed transversely7 through the button-hopper B, and upon one end of this shaft is a pinion j. The picker-arm is composed of two parts, the outer part having a fingerj2 for engaging the button-Shanks and is pivotally and yieldingly connected at jg to the inner part, so as to relieve too great pressure on the finger during its backward movement. A springjt, secured to the outer part and engaging a studf of the inner part, accomplishes this purpose. A rack-bar K, held by keeperplates 7c to side of frame A, engages pinion j', and at it lower end said rack-bar is pivotally connected by a pin Zo to wheel g5, so as to impart motion to shaft j. This rack-baris preferably made in two parts held together by a screw 7a2 to enable adjustment thereof, so that the exact relative position of the picker-arn1 can be secured.

L is the button-feed chute or tube, the upper end of which is projected through a hole or opening in the front wall of the hopper B, while its lower end is secured to frame A by screws passed through a plate Z, projecting therefrom, said plate completely concealing the stationary knife D and serving to hold the wire in the groove or recess e2. The connection of the upper end of the tube or chute is similar to that just described. In this tube or chute is an approximately spirally-arranged slot or opening Z', which decreases in width from its upper to its lower end. At the upper end of the tube or chute this slot faces outward and is widest at this point, and the same gradually winds toward one side of the chute and ends facing inward toward the clinchingbar or block, the lower end of said slot being coincident with that formed in said bar or block. By making the slot Z of gradually-decreasing width the button-shanks,no matter how they extended, therethrough when lirst dropped into the chute by the picker-arm J, are gradually brought around, so as to be properly presented to the clincher bar or block and in position to receive the wire. A portion of the lower front wall of this tube or chute is removed, and a flat spring Z2, secured to said tube or chute, projects thereover, so as to bear against the lowermost button and hold the same in proper position. The end of spring Z2 is slightly thickened to properly hold the lower two buttons.

M is the wire-feeding device, the saine consisting of an arm m, through which the wire is passed, and a curved arm fm', pivotally secured at m2 to a st ud m3, held by a screw m4 to the side of frame A, a slot m5 being formed in the latter arm, through which a screw m is passed to hold arm fm. to arm 'm'. By adjusting this screw the extent of movement of the arm fm can be regulated. A plate-spring n, secured to stud fm3and bearing against arm fm, serves to force the latter toward frame A. To arm m are pivotally connected two short arms n',

forming jaws for biting upon the wire. A plate-spring n2, secured to arm m and having the wire extended through an aperture therein, constantly bears against the outer ends 'of these jaws n. An arm n3 is rigidly secured to frame A, and through itand aplate-spring n, attached to said arm, the wire is also passed, two pivoted jaws 'a5 being also connected to this arm n3. These latter jaws serve to hold the wire while the arm In is being operated to gain a fresh bite on the wire and prevent the rearward movement of the latter. The curved arm m projects into the path of movement of the enlargement hjof bar or plate C, whereby when the latter is lowered the arm m is forced outward, and its jaws n', biting on lthe wire, will effect the feeding forward thereof when the bar or plate too C in its upward movement permits arms m and m to assume their normal position under the action of plate-spring n and the wire to be moved forward. The eXtreme end of the wire, after being projected across the mandrel and through the shank of the positicned button, strikes against a screw o, inserted through the side of frame A to prevent wear of the latter.

The operation of my improved stapling-machine is apparent from the foregoing and is substantially similar to that described in my allowed application for patent, Serial No. 384,708, filed March l2, 1891, but diers therefrom in that the wire is not kinked before being cut to form a staple, it being found that sufficient kink is formed in the bending ot the wire on the mandrel. The latter is withdrawn after the staple is formed'by one of the shoulders of the wheel Gr striking against the lip thereof, and the staple is finally clinched on the clinching-die by the shoulder g3 of said wheel bearing upon flange e6 of the clincher bar or block, forcing the latter down onto said die. machine described in said allowed application for patent, foot or hand power'can be used for eifecting the operation of the parts.

The advantages of my present invention are many. The machine is very compact and greatly strengthened. Instead of having a button hopper secured to the frame it is formed within the latter, and by extending the length of said frame the clinching-die is secured directly thereto, and hence is strong and durable. The wire-feeding device being automatic in its action,the feeding of the wire is sure and accurate. The mechanism employed for operating the mandrel is entirely within the frame and out of the way of the material to which buttons are being fastened. The cutting and bending bar or plate and also the mandrel are so setin the frame of the machine that its strength and durability are greatly increased.
