MACHINE FOR ATTACHING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 516,959, dated March 20, 1894.

Application filed February 27, 1893- Serial No. 463,816- (No model.)

To alt whom it may concern.-

Be 1t known that we, EMMET N. BARBER and JOSEPH H. WHITEHEAD, of Kent, county of Portage, and State of Ohio, have invented a new and useful Improvement in Machines for Attaching Buttons, of which the following is a specification, reference being made to the accompanying drawings.

Our invention relates to machines for automatically feeding button fasteners with buttons attached, to an anvil and die, by which the button fastener is clinched in the desired material, and the objects of our invention are to provide a simple and effectual device for feeding the button fasteners and connected buttons, and attaching the same to a shoe or other desired article directly from the receiver or raceway in which they are held.

In our machine the fasteners, with buttons connected therewith, are placed in a reciprocating chute or raceway and dropped automatically to the lower end of the chute, where each fastener is in turn engaged below by a die attached to a movable bar or support and pro ected against a movable anvil above, and the legs of the fastener thereby driven into the leather or other desired material and clinched in the same.

The staples are dropped to the position for.

being clinched by means of a feeding device attached to the movable chute, which device is operated by the alternate upward and downward movement of the chute as hereinafter more fully described.

Our invention is illustrated in the accompanying drawings in which like letters and figures refer to like parts.

In the drawings, Figure 1, represents a side elevation of the machine, one side wall of the 0 frame being partially broken out for the purpose of showing the movable die and anvil, and the means of operating the same. Fig. 2, represents a vertical section of a part of the chute, with buttons and fasteners engag- 5 ing the same, and showing in section the device for successively dropping the button fasteners. Fig. 3, is a vertical section of the lower part of the chute, the die and the end of the anvil bar, showing the position of these parts when the fastener is clinched. Fig. 4, 5c is an enlarged perspective view of the attachment to the chute for feeding the fasteners. Fig. 5, represents a section of the chute at the line x at in Fig. 1. Fig. 6, is a sectional view of the die, showing the end of the anvil, with fastener clinched, in this figure the eye only of the button being shown. Fig. 7, is an enlarged front view of the lower part of the chute showing the guides employed for holding the chute in the frame of the machine, and with a part of the chute removed, the upper part of the figure showing the vertical slot which admits the eye of the button. In this figure the end of the anvil is shown. Figs. 8 and 9, are enlarged front views of the prongs of the staple feeding attachment, showing a button fastener engaging the prongs, and showing the eye only of the button attached to each staple. Fig. 10, represents a button and staple of ordinary form. Fig. 11, is a view of a part of the chute showing the feeding de- Vice engaged by its operating spring.

In the drawings A in Fig. 1 represents the frame of the button attaching machine. The frame A is adapted to be secured to a table, bench or other suitable support. The frame A is provided with arms B. B. which are channeled to receive the chute O. The chute 0 is held in the channels of the arms B. B. by means of the guides 12. b. attached to the arms as is shown in Fig. 7, and moves freely upward and downward in its channel thus formed. The chute is prevented from dropping below the desired position by a pin a. or other suitable means of resistance in the chute, the pin coming incontact with the arm B. of the frame. The interior of the chute C is of suitable form to admit and hold the button fastener with the legs or prongs of the same pointing downward, and to allow the free passage of the fastener to the lower end of the chute. The exact form of the interior of the chute is however not material. In feeding the buttons and fasteners the button is suspended from the fastener by its eye, and 5 is guided in the machine solely by the fastener passing along the inside of the chute, the chute having a longitudinal out or slot 0 on its face shown in Figs. 5 and 7, which admits the eye of the button, and allows the button to move freely outside of the chute as lsshownin Figs. 1 and 2. The chute is raised by the die H when the same is thrown forward as hereinafter described, and when the die 1s dropped the chute returns to its original position byits gravity or is forced back.

by a suitable spring (not shown) bearing on the chute.

E in Figs. 1, 2 and4: represents the feeding attachment which is pivoted to the chute O at the points 1-1 or attached in any suitable manner. The attachment is provided with an extension (1 and the extension d is provided with suitable prongs 2-2 and 3-3 as shown in Figs. 4, 8 and 9. When the staple feeding attachment E is attached to the chute O, as stated its part d extendsiinto the chute through asuitable openingin the chute shown 1n Fig. 2. The extension cl is grooved at e to allow the free passage of the eye of the button in the chute C. When the chute C is raised, the attachment E comes into contact with a pin or other suitable point of resistance in the frame A atf, and the attachment is swung downward, and the lower prongs 3-3 of the extension (1 come sufficiently close to the inner wall of the chute to prevent the fastener from passing the lower prongs while in that position, as is shown in Fig. 2. When the chute is again dropped, the attachment comes in contact with the pin or other suitable point of resistance in the frame at g, and the attachment is again swung upward and the upper prongs 2-2 of the extension 01 come sufficiently close to the inner wall of the fastener chute to prevent the fastener from passing the same while in this position. The attachment E is held in its upward or downward position by means of the spring h, which is attached to the staple chute and which bears upon a pin 4 in the attachment E. In mov- 1 ng in either direction, the escapement or feeding attachment E is operated by the resistance pointsfand 9 until the pin 4 of the attachment passes the angle 8 of the spring 77. (as shown in Fig. 11), when by the action of the spring hbearing on the point 4 the attachment E is instantly thrown forward to the limit of its movement and strikes against the chute with a slightbnt sharpjar, and is retained in this position by the spring h as before stated. Thejar produced by the movement mentioned hasatendencyto freethe fasteners, whenfrom anycausetheylodgeorfail to dropin the chute. We prefer to use the spring, h, shown, but do not wish to be limited tothe use of this spring for this purpose, it being evident that other forms of spring might be used.

The operation of the fastener feeding attachment will be readily seen by a reference to Figs. 1, 2, 8 and 9. When the chute O is at its lowest position the upper prongs 2-2 of the extension cl come close to the inner wall of the chute and hold the fastener as shown in Fig. 9. When the chute is raised the feeding attachment swings downward, and the upper prongs 2-2 are withdrawn and the lower prongs 3-3 then come close to the inner wall of the chute, and the fastener then drops to the lower prongs as shown in Figs. 2 and 8. When the chute O is again dropped to its original position the attachment E is again thrown upward and the button fastener is dropped to the lower end of the chute ready for being clinched, and another fastener is engaged by the upper prongs 2-2 of the attachment. The chute O is provided with spring stops 5-5 attached to the chute at its lower end as is shown in Fig. 7, or in any other suitable manner, which prevent the fastener from dropping farther until the die H comes in contact with the chute in clinching the fastener, when the fastener is driven past the springs in the upward movement of the chute. In the lower arm G of the frame A, is a bar F which moves freely in a channel in the arm and forms a support for a die H of suitable form to turn the legs of the fastenerandcliueh the same. The bar F is operated by a lever K entering the bar or connected with it in any suitable manner.

In a suitable recess in the frame A is held a movable bar I, which is adapted to move freely in its recess and its end being of suitable form to project into the staple chute 0, through an opening at its lower end as shown in Figs. 3 and 7. The end of the bar I is grooved at Z to allow the passage of the eye of the button and also has a suitable concavity at 7 to lit the back of the staple when the staple is projected against the same from below, as shown in Figs. 3 and 6. The end of the bar I thus forms an anvil which, when projected into the chute engages the back of the fastener and holds the same while the legs of the same are being clinched by the die H below. In the drawings the bar I is slotted at 6 to admit the end of the lever J, and

a cushion spring 1' is placed in a suitable re- 'cess of the bar as shown in Fig. 1. The spring 1' operates with the lever J in projecting the end of the anvil barinto the chute. WVe prefer that the anvil consist of a single bar pro jecting into the chute as shown, but do not wish to limit our invention to a movable anvil constructed in one piece or to the specific means shown for projecting the anvil into the chute and withdrawing the same. The anvil bar is prevented from hearing against the inner wall of the chute when its end is projected into the chute by a suitable stop in the frame which engages the bar ats when the end of the same reaches the proper position in the chute. The frame has a suitable opening between the anvil and movable die II to admit the material to which the buttons are to be fastened. The levers J and K are connected at y and are provided with fulcrums respectively at 10 and 11. The machine is operated by foot power or other desired power applied to the lever K at O in any desired manner. The lever K is thrown IIO back after being depressed by a spring a or othJer suitable spring applied to the lever K or In operation the fasteners with buttons suspended therefrom are introduced into the chute with the legs of the fasteners projecting downward, with the eyes of the buttons sliding in the longitudinal slot 0 in the chute. Each fastener in turn engages the upper and lower prongs of the feeding attachment E and is dropped with its connected button to the lower end of the chute. The material to which the button is to be fastened is placed upon the die H, the lever K is depressed at O and the die H and its support are thrown upward, and by the same movement the lever J projects the end of the movable anvil I into the staple chute. The fastener is engaged below by the die H and above by the anvil I, the legs of the fastener are driven through the material and clinched as shown in Figs. 3 and 7. The reverse movement of the levers withdraws the anvil from the staple chute, lowers the die to its original position, thereby allowing the chute to drop. The chute in dropping reverses the feeding attachment allowing another button fastener to drop from the lower prongs of the attachment down in the chute to the point where it in turn is engaged by the die and anvil. Thus by the reciprocating action of the die H, movable anvil I and chute 0 each fastener is in turn dropped into position and clinched in the material. The end of the anvil bar I is projected into the chute before the latter starts in its upward movement, and thus is in place to hold the fastener from being pushed upward by the die H. After the anvil is in this position the cushion spring 45 holds the anvil in the chute while the leverJ withdraws. If by any means two or more fasteners are dropped to the bottom of the chute, and the machine operated no damage will be done to the machine, as the end of the anvil operated by the cushion spring 71 as described, would come in contact with the obstructing fastener in the chute and would not enter the chute. The cushion spring t' would take up the motion of the lever J and the fasteners in the chute would be driven past the end of the bar I, by the upward movement of the die H. If desired the lever J may have a friction connection with the anvil bar I.

We do not wish to limit our invention to the use of the specific combination of levers shown for operating the die and anvil as other combinations of levers might be readily substituted for those shownwhich would accomplish the same purpose.
