IBUTTON-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 479,705, dated July 26, 1892. Application filed March 12, 1891. Renewed June 29, 1892. Serial No. 438,376. (No model.)

Q i To a, whom it may concern.-

Be it known that I, CHARLES E. DENTON, a

citizen of the United States of America, re-

siding at Attica, in the county of Harper and State of Kansas, have invented certain new and useful Improvements in Button-Stapling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to button-stapling machines, having for its object the production of a machine of this class which shall be continuous in operation, simple in construction, and composed of a minimum number of parts.

The invention comprises a stapling -machine having a spring-impelled wire-holder, a vertically-moving cutting and bending bar or plate, a staple-forming bar or mandrel, and a clinching bar or block, all operated through the agency of a single wheel and its shaft.

The invention further comprises the detail construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of my improved stapling-machine with parts broken away. Fig.

2 is a front view thereof, the button hopper and chute being removed. Fig. 3 is an enlarged view of details. Fig. 4 is a similar view of the foot-treadle and its adjuncts. Fig. 5 is a transverse sectional view on the 5 line a; 00, Fig. 2. Fig. 6 is a detail view showing connection of button-tube to base-plate. Fig. 7 is a detail View of a modification.

Referring to the drawings, A designates a vertically-disposed frame or support, and Cb a 4.0 lower horizontal plate rigidly secured to or formed with said frame, and this plate is rigidly attached to a supporting stand or table (not shown) of any suitable shape. The vertical frame A is perpendicular on its front face and curved on its lower rear portion.

B is the cutting and bending bar or plate, capable of moving vertically. This bar or plate is held in place by two screws 1), projected through slots 1) thereof and secured to frame A, and by this means the bar or plate is held as against lateral movement. From the lower end of this bar or plate B project two parallel arms I) I), having grooves or recesses 12 in their inner opposite edges and similar grooves 12 in their lower ends for holding the staple ends. The outer lower edge of arm I) is inclined or angled, and is coincident with a removable stationary knife I), secured to the top of the front edge of plate a, and the same, in connection with arm 19, serves to cut or sever the wire. The plate a is preferably thickened where knife b is secured, so as to elevate the point of severance of the wire.

Ois the operating-shaft, mounted in frame A, and upon one end is rigidlysecuredawheel d, to which is connected the lower slotted end of a pitman d, the other end of said pitman being connected by a pin 61 to the bar or plate B, whereby the latter receives its up-anddown movement. Aboutthree-fourthsof the 7b periphery of this wheel is provided with cogs or teeth 01 and at the ends of such toothed portion are pins or shoulders 61 01 From shaft 0 projects a lug 6, located within frame A, and to the outer end of said shaft is secured a short hand-lever D, by which themachine may be operated directly by hand. It is, however, preferred to operate by foot-power, and hence to this hand-lever is connected the upper end of a rod 6, which at its lower end is connected to a foot-treadle E, fulcrumed to one of the legs to of stand W. A coil-spring e bearing on the legs to and against a crosspin of rod 6, serves to return the parts to their normal position and hold the treadle elevated. F is the clincher bar or block whose vertical side edges fit within the grooves or recesses b of bar or plate B. In the lower half of the bar or block F is formed a vertical slot f. A cross bar or plate f is secured to the front of bar or block F and its projecting ends engage pins f in the front face of arms I) b, whereby the said bar or block is moved upward with the cutting and bending bar or plate. From the rear of this bar or block pro- 5 jects a flange or shoulder f with which lug e of shaft 0 is designed to engage.

WVithin the lower end of frame A is a horizontally-disposed staple former or mandrel G, which consists of a T-shaped bar moving too in opposite grooves or recesses g in the side plates of frame A. This bar has a forward reduced end g, around which the staple is formed, and from the under side thereof projects a short arm g with which the pins or shoulders d d of wheel d will engage, thereby moving the said staple-former alternately frward and backward. This bar or mandrel also serves as a temporary support. for the button and staple and clincher baror block during the initial operation of forming the staple. To the under side of frame A is rigidly secured one end of an arm or support H, to the forward end of which is attached a die 71., upon which the staple is clinched, the same being directly beneath and in the path of the clincher bar or block.

ll is a button hopper or receptacle; h", a shaft passed transversely therethrough h', a jointed picker arm or finger secured on said shaft and having an outer pointed end; 71 a pinion on one end of, said shaft, and 71 a rack bar or rod held by keepers k and engaging the teeth of pinion 7L2 and Wheel d. By means .of this wheel (I and the rack-bar motion is imthrough the slot of the latter.

parted to the shaft and picker arm or finger.

I is a supply-tube suitably secured at its upper end to the button-receptacle H, and at its lower end it is provided with a plate 1, preferably formed therewith, and through which screws are passed for holding the lower end of the tube against the front edge of plate a. Said tube is slightly curved at its ends, and the upper end is projected up into and just above the upper portion of said hopper. In the rear wall of this tube is a continuous slot 2' for the button-shanks, and to the front of said tube, at its lower end, is attached a flat spring 11, which presses against the lower button in the tube, thus holding the said button in the exact position to which it may be forced by the upper terminus of the slot in the clincher bar or block until the wire is passed through the shank of the button and the bar or block is forced downward, carrying the button with it, during which time the force of the spring is still against the button. The weight of the buttons in the tube will force the next button along and cause its shank to project into slot f, and at this point the pressure of the spring will be brought to bear upon it, (the lower button having passed from under the same), and the shank of said next or second button will be engaged by the upper terminus of the slot and forced to exact position for reception of the next section of the wire. In this manner a continuous supply of buttons is had, each button being in position for the shank to receive the wire. The revolution of the shaft h and the picker arm or finger causes the latter in its back-and-forth movement to engage the shanks of buttons in the receptacle and carry the latter up and allow them to slide off into the upper end of the supply-tube, the shanks of the buttons being projected While in certain revolutions possiby no buttons will be gathered by the picker arm or finger, yet in others a large quantity thereof are secured, and in this manner a uniform supply is obtained.

To the front edge of plate a is secured a wire-feeding device J. The same consists of a tubej and a block j, wherein is fulcrumed a clutch-lever j having a lower weighted end j whereby the upper pointed end of said lever is made to bind firm against the wire as, which is passed longitudinally through the tube j, and the forward movement occurs only as the wire is out and used. Against this block j bears one end of a coil-spring 7' the other end of which bears against the outer end of tube j. This spring impels the block and its clutch-lever forward, and in this manner the wire is fed beneath the arms of the cutting and bending bar and also under the clinching-bar. The forward movement of the Wire is limited by the extreme end thereof being in contact with the inner face of wheel (1. When block j reaches the full extent of its movement, the operator disengages the leverj from contact with the wire and forces said block backward as against the action of the coil-spring, and upon allowing the lever to drop to its normal position its upper end will again engage and bite against the wire. If the wire should fail to pass through the shank of a button, it can be quickly drawn back by simply pushing the block, carebeing taken not to loosen the clutch.

Adjacent the forward end of tube j is the stationary knife 19 which latter is provided with aninverted-V-shaped lug or crest 70. Immediately above this knife is a small plate 70', pivoted at its inner end and designed when in its normal position to form a guide or passage way for the wire. This plate has a groove or recess corresponding with the lug or crest. A lug or projection k secured to one side edge of the bar orplate B, is designed at each operation to engage and bear upon the movable plate It and force the same down upon the knife, whereby a kink is formed in that portion of the wire which is to engage the shank of the button next provided with a staple. In lieu of the movable plate 70' the lug k can be located near the end of aunt, and extended to serve in place of said plate, the same results being thereby secured.

The operation of my improved button setting or stapling, machine will be understood from the following. (See Fig. 7.) The button hopper or receptacle is first supplied with bottons and the feed or supply tube filled with the latter, the lower one of which buttons has its shank extended into the slot of the clincher bar or block and so held by the spring. The wire is inserted through the shank of the first button,-and the kink therein engages said shank. The operator by bearing down directly on the hand-lever or pressing on the foot-treadle will force the cutting and bending bar or plate downward, and in connection with the stationary knife the wire will be cut diagonally, leavinga point thereon. The further movement of this cutting and bending bar or plate B carries the button and its wire downward until the latter bears upon the bar or mandrel G, and at this point the button and clincher bar or block are temporarily stopped, while the wire is bent around the mandrel to form the staple. The clincher bar or block will then be resting on said bar or mandrel, and the instant the lug e on the shaft 0 engages shoulder f of said clincher bar or block the bar or mandrel G is moved rearward out of the way by reason of pin or shoulder d of wheel 01 coming in contact with arm 9 As the latter reaches the extent of its movement the lower end of the pitman will have reached the limit of its movement;

but the slot in said pitman will allow the cut-.

ting and bending bar or plate to stand stationary while the lug e on shaft 0 forces the clincher bar or block farther down and clinches the staple around the button-shank, which is then supported on the die of arm H. The upper end of the slot f has then for some time been in contact with the shank of the next following button, which is then in exact position for the wire to pass through when the parts are elevated. The latteris effectedby the raising of the hand-lever, and the bar or mandrel G is returned to its forward position by pin or shoulder cl, of wheeld engaging with the arm of said bar or mandrel. The device is then in position for the above operation to be repeated. As the cutting and bending bar or plate was lowered in forming the first staple the wire was kinked by the plate lo, and hence said wire is ready for the next button. Thus it will be seen that in each operation the wire is cut and bent in one movement of the cutting and bending bar or plate, the staple is firmly clinched, a second button is fed, the Wire is kinked ready for said second button, and is automatically fed forward and inserted through the eye or shank of such button. A staplingmachine constructed as herein described is extremely simple, cheap and durable, and free from all complication, and in its entire structure only two springs are employed. It is also positive in its movement and there is little or no danger of its failing to fully perform all its'functions at each operation.
