Application filed August 3, 1889 -Serial No. 819,668. (No model.)

taching buttons; and it has for its object to construct a machine of this class-in which the buttons shall be automatically fed from a receptacle or hopper into a 'slotted tube, by meansof which they shall be con veyed to and held in the desired position while wire is being threaded through the eye of each successive button, by which the wire shall be severed andformed into staples, and by which the said staples shall be driven through the material or fabric to which the buttons are to be attached and clinched.

The invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of my improved machine for attaching buttons. Fig. 2 is aside view of the opposite side of the same. Fig. 3 is a vertical sectional view taken through the feeding-wheel. Fig. 4 is a vertical sectional view taken through the feed-tube and feedwhcel at'right angles to Fig.3. vertical sectional view taken through the plunger and anvil. Fig. 6 is a front elevation.

Fig. 12 is a detail View, the plunger at the end of its stroke. Figs. 13 and 11 are detail views of the bench and anvil.

Like numerals of reference indicate like parts in all the figures.

The base of my improved button-attaching machine consists of a tubular standard 1, mounted upon suitable legs or supports 2 2, and having at its upper end a horizontal annular flange 3, which is perforated to receive Fig. 5 is abolts 4, by means of which the machine may be attachedto the base.

5 designates a rod or plunger arranged to move vertically in the tubular standard and operated by means of a foot-lever or treadle 6, by means of which the said rod or plunger may be moved in a downward direction by the pressure of the foot of the operator. The plunger 5 is retracted or forced in an upward direction by the action of a coiled spring 7, suitably arranged within the tubular casing or standard.

8 designates a casing provided at its lower end with-a flange 9, by means of which it is attached to the flange 3 at the upper end of the standard 1. The casing S is provided with an angular bearing for a vertically-sliding rod 10, the lower end of which is suit-ably connected with the upper end of the vertically-sliding rod 5 in the standard 1. The vertically-sliding rod 10 is provided at its upper end with a cross-head 11, carrying parts of the operating mechanism which will be hereinafter more fully described.

12 designates a bracket, which is bolted or otherwise suitably secured to the casing S and which extends from the same in a rearward direction, and is provided with a bearing for a transverse shaft 13, carrying the feed-wheel lat and an annularly-grooved cylindrical roller 15, which constitutes one of the wire-feeding rollers. The bearing of the shaft 13 has an upwardly-extending bracket 16, atli'ording a bearing for a transverse shaft 17, upon which an additional Wire-feeding roller 13 is mounted. The

shafts

13 and 17 are furthermore provided with spur wheels or pinions 1.), meshing together and serving to transmit motion from the shaft 13 to the shaft 17, thus causing the wire-

feedingrollers

15 and 18 to be operated' simultaneously,when the feed-wheel 11 of the machine is in operation. A spool'20, holding the wire, may be mounted upon a suitable bracket in any desired position which shall enable the wire to pass conveniently between the feed-rollers.

The button-feeding wheel, which has been designated by 14, is composed of an annular disk of brass or other suitable material, one of the sides or faces of which is provided with an annular peripheral flange 21, having notches ing tube at the proper time.

22, to receive the ends of a series of horse shoe-magnets 23, which are suitably attached in any convenient manner to the face of the disk let. A bracket 24, forming an extension of the bracket 12, carries a suitablyconstructed hopper 25, the bottom of which is provided with a slot 20, to admit the rim of the disk 14, with its flange 21. It will be seen that when the wheel or disk 14 is rotated the magnets 23 will successivcl y pass through the slot 26 and finally escape at the upper or front end of the hopper.

To the upper front end of the hopper, and registering with the slot 26, is suit-ably attached one end of the button-feeding tube 27. Said tube, which may be constructed of suitable metal, is provided with a slot 28,extending through its entire length. The upper or rear of the said slot registers with the front end of the slot 26 in the hopper E35, and the said slot, which has a slight spiral twist, terminates on one side of the said tube, as will be clearly seen in Fig. 4 of the drawings.

The bracket 12 is provided with aforwardlyextending portion 29, which constitutes what I term the bench of the machine; or this bench portion maybe independently attached to the casing S. Extending longitudinally through the bench 29 is a shaft 30, the front or outer end of which is provided with an upwardly-extending bent or curved arm 31.

The bench 29 is provided with a vertical opening or recess 32 to accommodate the plunger, which will be hereinafterdescribed, and the rear end of said opening or recess is diagonal, as will be seen at The rear wall of the opening 32 is pierced for the passage of a knife or cutter 3i, which extends rearwardly and is provided with a longitudinal groove or opening 35, serving as a wire-guide. The knife or cutter is retained in position by means of a set-screw 36, extending through the side of the bench 29. This enables the said cutter to be con venienlly detached whenever desired for the purpose of sharpening the same. The side of the vertical opening 32 is open, as shown, at 37, and in the said opening is secured the lower front end of the button-feeding tube 27, the slot 28 of which terminates adjacent to the said opening The lower end of the buttoirfeedingtnbe has an inwardly-exten ding spring 38, which serves to hold in position the button which is to be attached, the said spring permitting the said 1 button to be readily removed from the feed- The bench 29 has in its upper side a transverse groove or recess 39, which communicates with the opeir ing 32, and which affords accommodation for an arm 40, extending from the shaft 30 at an angle to the arm 31 at the front end of said The said arm 40, which forms the i mandrel over which the staple is bent, is pro 1 shaft.

vided at its outer end with a notch 41, to enable the eye of the button to pass, as will be hereinafter explained.

42 designates the anvil, which may be made vertically adjustable by means of a screwthreaded support 43, by means of which it is secured to the iiange 9 of the casing 8. The top of the anvil has a head 44:, provided with a longitudinal notch 45, which is shaped in such a manner as to receive the ends of the staple and to turn and clinch them. In the construction of this device, however, no novelty is herein claimed.

The cross-head 11 of the vertically-reciprocating rod 10 is provided at one end with a pawl 40, adapted to engage a ratchet-wheel 47, which is mounted upon the shaft 13 of the button-feeding wheel 14. It will thus be seen that when the rod 10 is vertically reciprocated an intermittent rotary motion will be imparted to the said button-feeding wheel. This motion does not take place with any absolute regularity, and for reasons which will be presently set forth it is not necessary that such should be the case. The front end of the cross-head 11 carries the plunger 48, which works vertically upon the stem or shank 50,

and which when in a raised position abuts against the shoulder 5& at the upper end-of the stem or shank 50. The sliding portion or plunger 53 is adapted to move vertically in the opening 32 in the bench 29 of the machine, the rear side of said plunger being diagonal to correspond with the diagonal rear side 33 of the said opening. The sliding portion or plunger 53 has in its lower side a longitudinal groove 55, for the accommodation of the piece of wire from which the staple is to be formed, and the said sliding plunger is also provided with a transverse open ing or recess 50, adapted to fit over the arm or mandrel 40, over which the staple is to be bent, the front and rear walls of said recess being vertically grooved, as shown at 57. The upper end of the recess 56 has an upwardly-cxtending notch 58, registering with the notch 52 in the stem 50, for the accommodation of the eye of the button which is to be operated upon. The movement in an upward direction of the sliding plunger 53 is limited by the shoulder 54, as above stated. To limit the movement of the said plunger in a downward direction and to prevent it from sliding off the stem 50, it is provided with a pin 5!), extending transversely through a slot 60, which is formed vertically in the stem 50. The vertically-sliding plunger 53 is provided at its upper edge, on one side, with the hinged arm-(l1, adapted to it against theside of the plunger 48, which latter is provided with a block or projection (52, against which the upper end of the hinged arm 61 may abut when the sliding plungcr5 5 is at the lower end of its vertical movement. The hinged arm 61 is provided with a laterally-extending cam (33, adapted to engage a corresponding cam 64: on the bench 29, and which serves, when the plunger is moved in a downward direction, to engage the cam 63 and release the arm 61 from contact with the pro j ection 62, thus permitting the plunger 53 to slide or move in an upward direction upon serves, when the plunger is raised, to restore the arm Glto its normal position in contact with the block or projection 62. The front side of the vertically-sliding plunger 53 has at its upper end a recess 66, forming a camshaped shoulder 67.

The plunger 48 is provided with a camshaped projection 68, adapted on the downstroke of the plunger to engage the rearwardly-bent portion 69 of the arm 31, which extends radially from the front end of the shaft 30, journaled longitudinally in the bench of the machine.

It will be seen that the relative positions of the arms 31 and are such that when the arm 31 extends in an upward position previous to the downstroke of the "plunger the arm 40 extends laterally through the vertical opening or recess 32 in the bench 29 at a point directly below the wire which is being fed forward through the guide or groove 35 in the cutter 34:. lVhen the plunger is on its downstroke, the pressure of the plunger against the arm 40 will rock or oscillate the shaft 30. At the same time the cam or projection (53 strikes the bent portion 69 of the arm 31, thereby guiding the said bent portion over the shoulder 67 of the plunger 53. A

spring is suitably arranged to restore the shaft 30 and its

arms

31 and 40 to their normal position when the plunger moves in an upward direction.

My improved button-attaching machine is operated by means of a treadle 6, which serves to impart a vertical reciprocating motion to the rod 10, carrying the cross-head 11 and its attachment. On the downward movement of the cross-head the pawl 46 engages the ratchet 47 of the shaft 13, which is thereby rotated in the direction indicated by thearrow in the several figures of the drawings. A supply of buttons is placed in the hopper 25, said buttons being of the ordinary kind, provided with eyes that are formed usually of steel wire, said eye being the only metallic portion of the buttons. Such being the case, the buttons will be attracted by the horseshoe-magnets attached to the feeding-wheel, and the eyes of the buttons will naturally be found to adjust themselves between the arms of the said horseshoe-magnets. The slot 26 in the bottom of the hopper is contracted toward its wheel the buttons will be automatically detached from the magnets, and they now drop by gravity into the lower and discharge end of the feeding-tube. It will be seen that the feeding-wheel is operated by each operation of the stem 50. A suitably-arranged spring 65 deed, is this necessary. 'At the same time itis entirely immaterial if a button should be so deposited by each magnet, for the reason that the operation of the machine will be in no wise affected by the number of buttons contained in the feeding-tube. When the latter is completely filled, the result will simply be that any buttons which may adhere to the magnets will be brushed off from the latter when the discharge end of the hopper is reached. The wire-feeding device, which is attached to the shaft 13 and geared from said shaft to the shaft 17, serves to feed the wire which passes from the spool 20 between the

rollers

15 and 13, and from thence through the groove 35 in the cutter 34 into the vertical opening 32 in the bench of the machine. The wire, it will be observed,is fed by friction by therollers 15 and 1S,

and the latter will slip loosely upon the wire cient length of the wire has been fed, the feed automatically ceases. This is partly due to the wire-guide in the cutter 3a, which extends in a rearward direction to within a short distance of the discharge end of the feeding rollers, and which prevents any kinks from forming upon the wire. \Vhen in operation the plunger is moved in a downward direction, the sliding plunger will first enter the opening 32, and the' sharp rear edge of the movable plunger 53 will engage the front edge of the cutter 34 and sever the portion of the wire whichextends through the opening 32 and abuts against the front wallet the said opening. The severed portion of the wire will be found to extend through the eye of the lowermost button in the feeding-tube, the eye of which button is in alignment with the discharge end of the wire-guide in the cutter 34. The lower edge of said eye rests in the notch ll at the outer end of the arm 40, which extends transversely through the opening 32, and which serves to support the severed portion of the wire from which the staple is to be formed. The groove 55 in the under side of the plunger 53 will now engage the ends of the severed portion of the wire and force them downwardly on opposite sides of the arm 40, thus shaping the staple, the ends of the wire being accommodated in the grooves 57 in the front and rear walls of the recess 56 in the under side of the plunger. As the plunger descends, the bent portion 69 of the arm 3t bears against the side of said plunger, thus preventing the arm .0 from being thrown out of its approximately horizontal position While the staple is being formed. hen the staple has been formed, the bent portion 60 of arm 31 is engaged by the cam or projection 68 and forced laterally through the recess 66 and over the shoulder 67 of the plunger, thus permitting the arm 40 to descend and be thrown out of the way under the pressure of said plunger. During the time occupied by the preceding operations the plunger 53 has been retained in a lowered position upon the stem 50 bythe arm 61 engaging the block or projection 02 extending laterally from the plunger i8. The

cam 63 of the arm 61 now engages the cam (ll upon the bench 29, thereby throwing the arm 61. out of engagement with the projection .(32 and permitting the stem 50 to descend within the plunger 53. The notch or recess 51 at the lower end of said stem will thus engage and press against the upper end of the staple, the arms of which will thus be driven through the material to which the button is to be attached, and which is rested in the proper position upon the face of the anvil. The arms of the staple, having been forced through the material, will engage the recess 45 in the face of the anvil, whereby they will be turned inwardly toward each other and clinched by the continued downward pressure of the plunger. When the plunger recedes in an upward direction, the spring 70 serves to rest-ore the shaft 30, with its attachments, to its original position, and the arm 61 is likewise, by the action of the spring 65, restored to engagement with the block or projection 2, and the plunger, as soon as raised, will thus be ready for a repetition of the operation. Owing to the diagonal rear wall of the opening and the corresponding diagonal shape of the rear side of the plunger 53, the ends of the wire forming the staples will be cut otf diagonally, and thus be provided with pointed ends, which will easily penetrate the material to which the buttons are to be attached.

The advantages of my improved machine for attaching buttons will be readily appreciated by those familiar with this class of machines.

The construction is simple and of such a nature asnot to be liable to get out of order, and the operation offorming the staples and attaching the buttons will be performed with neatness, accuracy, and dispatch.

I have in the foregoing described what I consider to be the preferable construction of my machine for attaching buttons; but I would have it understood that I do not propose to limit myself to thc preeise construe tion of the device in its details which has been herein described, but reserve the right to make any alterations or modifications which may be resorted to without departing from the spirit of my invention.
