Nrran STATES JAMES F. THAYER, OF PROVIDENCE, RHODE ISLAND.

MACHINE FOR SECURING BUTTONS TO FABRICS.

SPECIFICATION forming part of Letters Patent No. 337,636, datedMarch 9, 1886.

Application filed January I, 1886. Serial No. 187,869. (No model.)

To all whom it may concern.-

Be it known that I, JAMES F. THAYER, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Securing Buttons to Fabrics; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to an improvement designed for use on machines for securing but-- tons to fabrics by means of metallic fasteners, one member of said machine holding the button or button and fastening, while the other is operated by suitable power to secure the button and fastening to shoes or other articles. In machines of this character heretofore made there have been no provision for the removal of the button and fastener from the holding member after being secured to the shoe or other article except by forcibly ejecting the same from the machine by hand, which method of removal is attendedwith serious difficulties, as it is of the utmost importance that the clinched fastener and button be re moved previous to placing the next button in position forattachment.

To this end my invention consists, primarily, in providing the button and fastenerfeeding mechanism with a movable pawl or ejector so constructed and operated in connection with said feeding mechanism that the clinched fastener and button will be ejected from the holding member of the machine previous to placing the next button and fastener in position for attachment to a shoe or other article, all substantially as hereinafter more fully described, and pointed out in the claims.

To illustrate the operation and use of my improvement I have shown and described in the accompanying drawings and specification my invention as applied to the machine patented January 20, 1885, by J. O. F. Dick, No. 310,934, to which I refer for a full detail of the entire machine.

In the accompanying drawings, Figure 1 is a front View in partial section of the head of the machine, showing the location of my improvement. with relation to the feeding mech anism and clinched fastener and button; Fig. 2, alike view showing the ejector in position for removing the button and fastener at the next movement of the feeding mechanism. Fig. 3 represents the same with the ejector in the act of removing the clinched fastener and button; Fig. 4, a top plan View of the ejector as attached to the feeding mechanism; Fig. 5, a side elevation of the ejector-provided with an adjustment. Fig. 6 is a side elevation of the upper portion of the stationary head of the machine,showing thelocation of the ejector with relation to the slot in the same. Fig. 7 is a cross-sectional view of'the inclined raceway.

In the drawings, D represents the head of the button-attaching machine shown in the patent to Dick, referred to, corresponding in a general way with the upper or button-hold ing jaw of a hand instrument, constructed rigidly upon a standard. To one side of the head is secured an inclined raceway or chute, E, composed of two parallel sections, affording a longitudinal slot, through which the button and fastener are moved by their own gravity, the button-stop i arresting their progress in said raceway. The bell-crank lever Z is pivoted to the head D, as shown, and is operated at its upper end by the cord a through the medium of the rear portion of the reciprocating jaw O,'which clinches the fastener when operated upon by the treadle or other suitable power. At the lower end of the bellcrank lever Z is pivoted the feeding-finger K, which is carried rearward and forward by said bell-crank lever. This comprises the feeding mechanism of this machine, the outer end of the finger K dropping behind abutton when the treadle is at its downstroke, and upon the upward stroke the finger K moves the button longitudinally along the slot in the raceway E into position in the head D for clinching, which is accomplished by the jaw C. On this feeding-finger K,I have placed my improvement, in the present instance secured at the outer end by the pivot a. This iml provement consists of a movable pawl-shaped ejector, a, pivoted, as described, to the feedingfinger K, and is operated by said finger, as shown in the drawings. The pawl-shaped ejector a lies loosely over the but-ton when it is being secured to the shoe or other article, as shown in Fig. 1.

After the first button is seen red to the shoe or other article, the feeding'tinger K is moved rearward by the power applied, which causes the ejector a to ride lightly over the clinched button until its outer end is at the rearof said button and the end of the feeding-finger K has dropped back of the second button in the raceway, as shown in Fig. 2.

The next movement of the machine causes the feeding-finger K to move forward longitudinally on the raceway, carrying with it the second button, and forcing the ejector (4 against the rear of the first button, and as the forward movement is continued ejects said button and clinched fastener from the holding member of the machine, as fully shown in Fig. 3, the feed ing-finger leaving the second button in position for attachment at the completion of the movement.

The pivoted portion of the cjcctora maybe provided with an adjustable screw, as shown in Fig. 5, so that the distance the button is ejected from the holding member may be regulated. This renders the ejector useful in spacing the distance between each button attached without the necessity of marking the shoe or other article to which the button is to be secured.

As previously stated, I have shown and de scribed my improvement in connection with this particular machine for ejecting a clinched button and fastener. It is evident,that without departing from the construction of my improvement materially, the ejector may be used with like result on any of the various machines for secui ing buttons now in use, and also on machines for securing lacing hooks, staples, or other similar devices which require a feeding mechanism to place them one by onein position for attachment; to material, and in which it is required to remove the first de vice secured to make room for the second.

The ejector a may be pivoted to the feedingfinger K in any convenient place, back from the end, so long as not to disturb the relation between the ends of each, with regard to the button to be fed from the raceway. The outer end of the ejector is preferably made concaved, as shown, or angular, to retain a more firm hold on the under edge of the button in ejecting the same from the raceway.

Having described my invention, I claim- 1. In eon'ibination with the feetlingdinger of a button-attaching machine, a movable button ejector, as arranged with relation to said feeding mechanism, to precede the latter and eject the button previous to feeding the next button into the holding portion ot'the machine in position to be attached to i'naterial, all substantially as herein set forth.

2. In a machine for attaching buttons to fabrics, and in combination with the buttonfeeding mechanism of said machine, a movable pawl or ejector, as constructed and arranged with relation to said feeding mechanism as to precede the same and eject from the attaching portion of the machinethe attached button before feeding the next succeeding button into position for attz'ichment.

3. In combination with the feeding mechanism of a lmtton-attaching machine, a movable pawl or ejector, said pawl or ejector provided with alougil udinal adj ustment constructed to precede the feeding mechanism and eject a button from the holding member of the machine a greater or less distance from said holding member, substantially as herein set forth.

4. The combination, substantially as herein described, of a slotted stationary button-holding jaw jn'ovidcd with an int-lined raceway or chute having a longitudinal slot communicat' ing with theslot in the holding-jaw, a feeding fiuger provided with a movable lmttonejcctor, arranged to precede said fcedinglingcr and eject the first button secured previous to the placement in snid holding-jaw ofthe next butllOll t0 b8 StUlll'Uil.

In testimony whereof I affix my signature in the presence of two witnesses.

JAMES F. THAYER.
