MACHINE FOR ATTACHING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 335,211, dated February 2, 1886.

Application filed November 9, 1885.

To all whom it may concern.-

Be it known that I, CORNELIUS J. BROSNAN, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Machines for Attaching Buttons, of which the following is a specification.

This invention relates to improvements in machines for attaching buttons, and is in the nature of an improvement upon my patent of October 6, 1885, No. 327,917, the object being to provide improved means for securing the positive movement of the button and the fastener or tack from their respective chutes into the troughs which lead to the place on the machine where they are fastened to the material, and to provide improved tack-clamping mechanism under the anvil.

A further object of this invention is to provide, in combination with the machine embracing said improvements, improved button and tack feeding devices, and improved means for holding the button while it is being fastened onto the material.

In the drawings, forming part of this specification, Figure 1 is a perspective view of the machine, the lower part of the frame and the lower end of the pedal-connecting rod being broken away. Fig. 2 is a front elevation of that part of the frame supporting the anvil and tack-clamps, and of the front end of the button-trough, showing a button in position to have the fastening-tack pass through its eye, said tack and the clamp-springs being shown in dotted lines. Fig. 3 is a side elevation of the parts referred to in the description of Fig. 2, showing the front parts of the frame and the button and tack troughs, the upper 0 end of one of the clamps being broken away and the clamp-block being shown partly in section, in order to show the tack plunger or lifter and the tack in full lines, the latter being in the position when it is about to enter the eye of the button. In this figure (3) are shown in dotted lines the lower end of the button-plunger and the end of its operating-arm.

Fig. 4 is a side view of the front end of thebutton-trough; and Fig. 5 is a cross-section of the same on line a as, showing the laterallygers are attached, the connection of said car- Scrial No. 182,178. (No model.)

moving button-holder and the end of its spring in full lines. Fig. 6 is an enlarged view of said button'holder in perspective. Fig. 7 is an elevation of a part of that portion of the machine at the lower end of the button-chute, Fig. 1, showing the lower end of the latter in dotted lines, a part of the button-plungcr and the button-trough, and the devices by which the button is transferred from the chute to the latter. Fig. 8 is a view taken transversely on line 00 m, Fig. 7. Fig. 9 is an elevation of the rear side of the button-carrying wheel. Fig. 10 is a plan view under the button-trough, showing a part of the frame in section and the carriage to which the button and tack plun- 6- riage with the rock-shaft, a portion of the arm on the latter to which the foot-pedal is connected, and of the button-plunger shank, the taclctrough, the lower end of the tackchute, and the mechanism which controls the movement of the tacks from the chute into the tacktrough. Fig. 11 is a similar view to Fig. 10, but showing said tack-controlling mechanism in a different operative position to that shown in Fig. 10.

The mechanism shown and described in my said patent for moving the buttons and fasteners to the front end of the machine under the anvil, where they are united on the material, for operating the vertically-moving tack-carrier and the anvil itself, are substantially the same as those parts of the machine which are the subject of this application.

The construction and operation of the tack- 8:, reservoir and feeding mechanism J is that L shown and described in my patent dated October 27, 1885, No. 329,268, to which reference may be had.

The improvements embodied in the buttonreservoir and feeding mechanism H form no part of the subject-matter of this application, but the construction and operation of said button-feeding mechanism are clearly set forth in another application for a patent, which is filed by myself simultaneously with this, dated November13, 1885, Serial No. 182,700.

In the drawings, A is the frame of the machine, (the lower part thereof being broken away,) which is in practice adapted to be attached to a suitable table, under which is hung a treadle, and to the latter the connecting-rod F is attached, its upper end being pivotally connected to the arm E on shaft 0. A suitable retracting-spring is attached to said connectingrod to draw it downward, and by means of said treadle and spring a rocking motion is given to said shaft, which runs transversely across the frame A, the part of the latter in which said shaft has its bearings being hollow and open at the rear side, to permit of the requisite vibratory motion of arm E.

The button-trough t and the tack-trough h are arranged parallel to each other, and have operating in them plungers which are given areciprocating motion, as in said patent, to carry abutton and a tack simultaneously under the anvil 8, said reciprocating motion of the plungers being imparted thereto by the yoke or carriage d, (see Figs. 1 and 10,) the latter being connected by a short connectingrod, 22, with an arm, 21, attached to the rock shaft 0. The lower end of said carriage enters the tack-trough h, and said tack-plunger is attached to said end, substantially as shown in said patent. The button-plunger proper, g, is attached to the carriage d by the shank g. The anvil 8 is fixed in the front end of the frame A, and is constructed substantially as in said patent. The button-trough 2' extends to the front of the anvil, and lies close by the side of the latter, as shown in Figs. 1 and 3, and opposite the anvil in said trough islocated the laterally moving button holder 15, (see Fig. 6,) its body of cylindrical form, havinga square head, (or substantially S0,) 20, and a wing, 19. Saidbutton-holder is inserted in the button-trough t in the position shown in Figs. 2, 4, and 5, and is held normally in that shown in Fig. 2 by a flat spring, 16, having a bifurcated end engaging with the head 20 of the holder, said spring being secured on the outside of the said trough by a screw, as shown in Fig. 4 in dotted lines. The holder has a lateral movement toward and from the side of the anvil 8, the spring giving it the former action, and when a button is carried through trough i to the side of the anvil it encounters the curved end 18 of the holder, forcing the latter back against the spring, and when the button-plunger retires the latter forces the holder against the button and the latter against the side of the anvil, holding it in the position shown in Fig. 3, with its eye in a position to let the fastener 24 pass through'it, and the latter being by the carrier 17 forced against the anvil is made to pass through the material to which the button is to be attached and to be hooked around the button-eye, as set forth in said patent. The next button that is carried to the anvil drives the one before attached out of themachine, or from between the said holder and the anvil.

The rear side of the clamp-block 9 is cut away, as shown in-Fig. 3, opposite the endof' the tack-trough h, to allow the fastener 24 to.

pass from the trough into the block to the position shown in Fig. 2, when the carrier 17 is down, the upward movement of the latter carrying the fastener to the position shown in Fig. 3; and from that to the one above described, which completes the fastening.

The tack-clamps 10 10-arepivotedin grooves on each side of the clamp-block 9, as shown, and between the inner side of each clamp and the adjoining side of the groove in which it is pivoted is secured a flat spring,(shown in dotted lines in Fig. 2,)whose upper end engages in a notch inthe clamp. Said springs hold the upper ends of the clamps 10 together, and when the tack 24 is forced up between them the latter is caused to enter between two opposite notches in the clamps, and thereby and by the action of said springs is made to take a proper position, and is so held as not to be easily moved from said position.

l The chute 0 from the tack-feeding devices J is connected to the side of the tack-trough h, as shown in Figs. 10 and 11, and the tacks move by gravity down the inclined chute to the side of the trough; but to prevent more than one tack at a ti mefrom entering or partly entering said trough, and to hold back the tacks which are behind the lower one and to positively place the latter one in said trough, the following described mechanism is applied to this machine.

I A slide, it, having oblong screw holes through it, as shown, is, by screws on which it slides, attached to the side ofthe tack-trough h. A vibratory tack separator and mover, 0, is pivoted on the slide at, and has a vibrating motion in the plane of the tack-trough. One end of the-separator is of wedge shape, and on one side, near its opposite end, is a laterallyextending short arm, againstthe end of which the spring in bears, the latter being attached to slide a, and on the opposite side of the separator is a laterally-extending hook, as shown. A rod, 3, is connected with the rear end of the slide 12, and extends rearwardly, passing through the arm s on the carriage d, as shown in Fig. 10. Rod 2" is provided with two nuts or abutment-blocks, a: 00, between which the arm 8 has a reciprocating motion, whereby the slide a and the separator thereon are moved toward and from the side of the tacktrough 0, their movement toward the latter bein the trough it onto the carrier 17, and by said movement of the carriage the slide n'and the separator are moved-about to the position shown in Fig. 10, letting the tacks take substantially the positions there shown. The reverse rearward movement of carriage d causes slide a to move toward the chute c and the pointed end of the separator to be introduced between the two tacks nearest said trough. The hook on the separator then engages with pin 23, causing said separator to vibrate and carry its free end against the tack nearest the trough h, moving it into the latter, as shown in Fig. 11, and holding back the other tacks. Vhen the slide it and the separator move from the chute c to reassume the positions shown in Fig. 10, the spring m, acting on the afore said short arm on the side of the separator, swings the latter to said position, the pin 23 by said movement of the slide a being disengaged from said hook.

In my said patent the buttons move from the chute by gravitation, entering the buttontrough one by one through an opening in the side of the latter, said chute being connected directly to said trough. In practice it is found that the movement of the buttons by gravitation from the chute into the trough is not sufficiently positive to insure such a constant supply of buttons at the anvil as is desirable, especiallywhen the buttons must move in a curved chute in order to bring them into proper position when they enter the buttontrough, whereby the eye of the button,when the latter arrives at the anvil, is extended under the latter, as in Fig. 3, and to render the movement of the buttons positive from the chute 0, which conducts the buttons from the reservoir H into the trough t, the below-described mechanism receives the buttons one by one from said chute and deposits them in trough t in said requisite position.

A wheel-support, D, (shown in Fig. 1 and in enlarged views in Figs. 7 and 8,)isattached to the upper side of frame A at the lower end of the chute c, and nearly opposite the said opening in the side of the trough i7, through which the latter is supplied with buttons, the upper part of said support extending over the tack-trough and nearly to the trough A wheel, 1 (shown, respectively, in edge and front elevation in Figs. 7 and 8,) is pivoted on the side of support D opposite the end of the button-chute 0, the position of the end of the latter relative to the wheel being shown in dotted lines in said Fig. 7, the end of said chute being attached to the center pivot, 28, of the said wheel, or in such a position as to bring the channel in the chute to correspond with the slots 3 in the periphery of the wheel. The rear side of wheel y has a series of wide ratchet-teeth, (one to each space between slots 3,) 6, on its rear side, as shown in Figs. 7 and 9, and between said slots pins 2 are inserted in the periphery of the wheel. The slots 3 serve to receive the eye of the button, as shown. The wheel rotates in the direction of the arrow on Fig. 8.

Apawl-carrier, f, having oblong screw holes orslotsthrough it, is secured on the upper end of the support D by screws passing through said slots to allow said carrier to have a reciprocating sliding motion on the support. The rear end of carrier f is inclined to its direction of motion, as shown, and a spring, 7, secured between it and frame A,serves to move it toward the latter. Two posts, 5, one bc hind the other in Fig. 8, depend from the under side of carrier f, and in the one nearest the vertical side of the support D is pivoted the pawl 4, against the rear end of which the free end of the spring o (which is attached to the end of the carrier) bears, serving to swing the pawl to the position shown in Fig. 8, the end of the latter lifting slightly as the pawl retires after having moved against one of teeth 6 to rotate wheel A stop-arm, w, is pivoted to the lower part of support D, and has a vibratory motion caused by the movement of one of pins 2 on wheel y against its inclined edge near its free end, and the spring z,whicli bears against its opposite edge. Vhen said wheel is rotated, as hereinafter described, and is brought to a proper position to deliver a button into trough t, the upper end of arm 10 swings under one of pins 2, as shown, and the outer one of said posts 5 is brought by the forward movement of the carrier f over said pin, thereby preventing said wheel from having inadvertently any movement at the instant that itdischarges its button into the trough, whereby the button might fail of proper placement.

A carrier-actuating bar, 0, having a beveled end, as shown in Figs. 1 and 7, is attached by one end to the carriage d. and by the latter is given a reciprocating motion in adirection at right angles to the carrier f and opposite its inclined end. A guide-spring, 14, extends from the upper side of trough i (see Fig. 8) over the wheel 3 against which the button is carried when moving toward the trough i,and whereby it is held steadily in engagement with the wheel until it is deposited in the said trough. A steady-pin, 1.3, is placed in sup port D, over wheel 1, beneath which the button is delivered from chute c, and whereby it is prevented from being displaced by the crowding against it of the buttons back of it.

The tack-reservoir J and button-reservoir H are both secured on the shaft K, which has an intermittent rotary motion in suitable bear ings in the arms B,which are secured to frame A, said motion being given to the reservoirs by means of ratchet mechanism connected with said shaft and the arm a, (as described in my said patent,) the latter being connected to arm 1) on the rock-shaft C by the connecting-rod a. Said reservoirs operate to separate and deliver therefrom, one by one, tacks and buttons into the chutes c and c, which are placed in each of said reservoirs in a mass, the operation of each being fully set forth in the above-named patent of October 27, 1885, and in my said application for a patent. The tacks from the reservoirJ follow the chute 0 directly to the side of trough h,

and are admitted to the latter, as above described. The buttons in like manner follow the chute c, and from the lower end of the latter are lodged, one by one, by gravitation on the wheel yin the position shown in Fig. 8.

The operator stands in front of the machine, holding the material, leather, or cloth, upon which the button is to be fastened, between the anvil and the clamps 10. When the operative parts are at rest, or before the said foottreadleis operated, the button and tack plungers are in a rearward position, leaving the troughs free to receive a button and a tack in front of the ends of said plungers, and when the latter are in said position the end of the bar 6 is retired rearwardly, thus having permitted spring 7 to slide the carrier f toward trough i, and causing pawl 4 to engage with and rotate wheel 1 and carry the button thereon over and drop it into said trough. The operation of the foot-treadle then causes said plnngers and the said bar 6 to move forward, the latter striking the inclined end of carrierf and sliding it to the position shown in Fig. 8, and the plungers moving said button and tack forward under the anvil, as above described,where they are attached to the fabric by the action of the tack-carrier 17, as above described, after which the parts retire to repeat the operations. The wheel 3/ is prevented from rotating by the backward motion of the pawl 4, as its end drags over the edge of the teeth 6, by the pivoted arm w, which during said motion of the pawl occupies the position under pin 2 of the Wheel. (Shown in Fig. 7.)

What I claim as my invention is 1. In a machine for attaching buttons, the combination, with the button reservoir H and the button-chute 0 leading therefrom, of the wheel 1, located at the end of said chute and having radial slots in its periphery to engage with the shanks of the buttons as they escape from said chute, the button-trough z,t0 receive the buttons from said wheel, and a reciprocating pawl carrier having a pawl thereon engaging with said wheel, whereby the latter is intermittently rotated, substantially as setforth.

' 2. The button-carrying Wheel y, provided with ratchet-teeth, substantially as described, and having the pins 2 in its periphery, the pawl-carrier f, having the pawl 4 pivoted thereto, the bar 6, having a reciprocating movement at the end of said carrier, the spring 7, and the pivoted stop-arm to, combined and operating substantially as set forth.

3. In combination, the button-reservoir H, the chute c,to convey buttons from the latter, the wheel 1, located at the end of said-chute and having radial slots in its periphery to engage with the shanks of the buttons as they escape from said chute, the button-trough 1;, to receive buttons from said wheel, the button-plunger g having a reciprocating motion in said trough t, and the reciprocating pawlcarrier f,having a pawl thereon engaging with said wheel, substantially asset forth.
