BUTTON-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 368,141, dated August 9, 1887.

Application filed May 13, 1887. Serial No. 238,107. (No model.)

To all whom it may concern:

Be it known that I, LOENDER O. Ennnson, a citizen of the United States,residing at North Graftomin the county of \Vorcester and State of llIassachnsetts, have invented certain new and useful Improvements in ButtoirFeeding Mechanisms for Button-Setting Machines, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to a button-feeding mechanism for button-setting machines, the said invention being more especially adapted for operation in connection'with the form of button-setting machine shown by United States Patent No. 341,053 to F. H. Richards.

In my invention I use a rotary buttoncarrying head or carrier, which takes the place of the die'holder in the patent above referred to. This rotary head or carrier is provided with a series of retainingsprings for the buttons and with a series of setting dies or anvils, against which the fasteners are forced by the d river to bend them in proper shape to hold the buttons on the shoes or fabrics to which they are to be attached. In connection with the rotary button-carrier-I employ a movable chute or roadway, which conducts the buttons from the box or rcceptaclein which they are contained to the said carrier, and thelatter is intermittingly rotated by a pawl-and-ratchet mechanism connected by a rod with the treadle by which the driver is operated. The movable button-conducting roadway or chute is reciproeated by a lever operated by the pawl-carrier, which actuates the rotary button-carrier, and by a retractingspring. The said chute is moved toward the button-carrier, so that it may force a button into the same when the treadle is operated; but before the chute begins its retreat from the carrier the latter commences its rotation, and thus removes the button from the spring-holding fingers at the lower end of the chute before the latter moves away from the carrier. A partial rotation of the I carrier brings the button into position to be set at the next blow of the driver, so that while one button is being set another is being placed in the carrier preparatory to the setting operation.

In the drawings, Figure 1 is a front view of a button-setting machine with my invention ap plied thereto. Fig. 2 is a side view of the same. Fig. 3 is a detail plan view showing the button-chute in section in the position it occupies when placing a button in the carrier. Fig. 4 is a partial section on line 4 4, Fig. 2, and with parts in the same position as in Fig. 3; and Fig. 5 is a detail view of the buttonchute.

A denotes the frame of the machine, the said frame being in practice supported by an iron c0lumn,which incloses the treadle-rod for operating the driver.

13 is a vertical post in which the driver (not shown) reeiprocates, and C is the magazine to contain the fasteners, all as in the patent above referred to.

D is a support or bracket, which is screwed to the frame A, the said bracket having a dovetailed recess or guideway, d, for the reception of a dovetailed projection on a slide, E, to which is attached the button box or receptacle F. The button roadway or chute G is attached to the base-plate f of the button-box F, the said chute having a quarter turn or twist, as shown in Fig. 5, to bring the buttons from their position with their heads down, in which they enter the chute, to a positionin which the shanks will be horizontal, as in Fig. 3. The said chute is provided at its lower end with re taining-springsg and g, to prevent the buttons from falling out and to hold them when being presented to the rotary button-carrier. The buttons in the box F are forced into the chute G by an ordinary agitatingbrush operated in any suitable manner.

I is the rotary button-carrying head or carrier, having a shaft, 2', which has a bearing in the top of the frame A, the said shaft having a ratchet-wheel, H, engaged by a spring-pressed pawl, 71, pivoted to a lever, J, and the latter is pivoted on the shaft 2' and is provided with a roller-stud, h- A rod, J, connects the lever J with the treadle by which the driver is operated, and a detent-spring, h", prevents the backward movement of the wheel H. bracket D has a depending arm or hanger, d, to which is pivoted a bell-crank lever, K, the lower arm of which is in position to be acted on by the roller-stud h on the pawl-carrying The of the said head to receive the heads of the buttons. Opposite each of the springs t" is a setting die or anvil, M, constructed, as shown in the patent referred to, with a recess of proper form to bend over or'clinch the fasteners.

The operation of my device is as follows: When the treadle (not shown) is operated, the downward movement of the rod J depresses the outer end of the pawl-carrying lever J, and the roller-stud h thereon engages the inclined outer 'end, k, of the horizontal arm of the lever K, thus turning said lever on its fulcrum and causing the slide E, connected by the link L to the vertical arm of the said lever, to move to the left, Fig. 1, and thus thelower end of the chute G will move into engagement with the rotary button-carrier I and place a button in the said carrier behind one of the holdingsprings t. When the treadle is released, a suitable retracting-spring (not shown) in the supporting column of the machine forces the rod J upward, causing the pawl h to engage a tooth of the ratchet-wheel H, and thus give a quarter-turn to thecarrier I,"bringing the button above the post B into position to be set. During the first part of the operating movement of the pawl-carrier (as the rod J moves upward, as just described) the rollerstud h will traverse the curved portion of the horizontal arm of the lever K before it rides down the inclined end-k of the said arm, and th us thesaid lever will remain at rest,with the button'chute still in its forward position, until a partial rotation of the carrier I has been effected and the button has been carried downward out of the lower end of the chute, the springs y and g'yielding to release the lower button from the chute,butimmediatel y retracting to prevent other buttons from escaping. As the roller-stud h rides down the inclined end is of the lever K, the retracting-spring N, acting through the lever K, link L, slide E,

and the button-box, (to the base of which latter the button-chute is attached,) returns the chute to its original position. The next downward movement of the rod J sets the button now brought into setting position above the post B and causes the forward movement of the chute G to place another button in the r0- tary carrier Land thus the button feeding and setting operations will be repeated as rapidly as the treadle can be worked. 1

I do not wish to be understood as limiting my invention to the precise details of construction herein shown and described, as such details may be varied within the limits of me chanical skill without departing from the spirit of my invention. Forexamplathe ro' tary head or carrier I, instead of having four button-holding springs and four setting-dies, as herein shown, (and being thus adapted to perform a quarter-revolution at each operation of the treadle,) might have a greater or less number of these springs and dies, and thus be adapted to be rotated through a greater ,or less portion of a circle at each operation of the treadle.

I claim- 1. In a button-feeding mechanism, the combination herein described,with a rotary buttoncarrier provided with button-holding springs and setting dies or anvils, of a reciprocating button-chute adapted to approach the said carrier to place the buttons therein, substantially as set forth.

2. In a button-feeding machine, the combi- .nation, with the rotary button-carrier I, having the holding-springs c" and the setting dies or anvils M, of the ratchet-wheel H, the pawlcarrier J ,having the stud l1 ,the spring-pressed pawl h, the bell-crank lever K, and the movable button chute with which the said leveris operative] y connected, substantially as set 'forth.

3. The rotary head or button-carrier I,hav-

ing on its front face the disk '6', of less diameter than the said head, combined with the button-holding springs 1', extending beyond the periphery of the said disk, substantially as set forth.

In testimony whereof I affix mysignature in presence of two witnesses.
