TOOL FOR APPLYING SHOE BUTTONS.

iApplication filed April30, 1926. Serial No. 1 l5,85 5.

This invention appertains to tools and more particularly to a novel device for applying buttons to shoes and the-like.

The primary object of the present'invention is to provide a buttonin'g tool embodying automatic means associated dlrectly with the tool for ejecting the'button and leather from the' tool after the button has been clinched in' placeby the tool.

H Another salient feature of tl18.111V Ilt10n1S the provision of an ejecting arm plvotally mounted on one arm of the tool and movable into and outof the path of the button by the operation of the sliding button carrler.

A further object of the invention is the provision of novel means for h0lfllllg tll button in place and the fastener in place during the operation'of the tool and noyel means forclinching the fastener, so as to insure the proper insertion of the shank ofthe fastener through the eye of the button without danger of displacing the button during the operation of the'tool.

A still further object of the lHVBHtlOII 1S to providea novel tool of'the character described whichwillbe durable and etficie'nt in use, one that will be simple and easy, to manufacture and one which can be placed upon the'market at a'reasonable cost.

With theseand-other objects in View, the invention consists inthenovel construction,

arrangement and formation of parts, as will be hereinafter more specifically described, claimed,-and illustrated in the accompanying drawings, in which:

F igure 8. is adetail section taken on the line 8-8 of Figure 5looking in-the-direction of the arrows illustrating the means of mounting the sliding plunger on the upper arm,

Figure 9 is a detail perspective View of the fastener employed for the button,

Figure 10 is apersp-ective view of the button and fastener after the fastener has been 15 having the forward end thereofprovided with a splitsleeve 16 for reciprocably receiving a plunger orpin'l'l' the purpose of which will be hereinafter more fully described. The sleeve 16 on each side of the split portionthereof isprovided with alined cars 18 for the reception of a. screw 19 for adjusting the sleeve about the plunger or pin 17. The

rear end of the arm 15 is provided with a suitable manipulating handle 20. Ata point inward ofthe sleeve 16, the arm 15 is provided with a depending leg 21 havingthe forwardly extending foot 22 which terminates directly below and in vertical axial alinement with the sleeve 16. As shown the .foot 22 is arranged in substantial parallel relation to the arm 16. The inner face of the foot 22 is provided with an integral attaching block 23, the forward end of which at its inner face is provided with a recess or seat 24L- for the disk shaped base 25 of the fastener 26forthe button 27. The block 23 has associated therewith the meansfor holding the fastener 26in position during the application of the button to the shoe and this means consists of a U-shaped spring 28 23. This forms an effective means for allowing spreading of the arms without dislacement of the spring from off of the block or saddle. The forward ends of the arms 29 of the spring 28 on each side of the seat or recess 24 are provided with upstanding inwardly directed gripping ears 32, which are adapted to engage the disk shaped base 25 of the fastener 26 when the same is slid into the seat 24. It is to be noted at this point that the fastener 26 is provided with a pointed penetrating shank 33 which is adapted to be clinched through the eyelet of the button.

The inner end of the plunger has the opposite sides thereof flattened as at 34 and the extreme inner end thereof is provided with an anvil 35 which serves the function of clinching the shank 33 through the eyelet 36 of the button 27. This anvil forms one of the features of the invention and is provided with a straight inner guide face 38, which gradually leads into the arcuate face 39 which forms the means for clinching the shank. The inner edge of the anvil is slightly beveled or rounded as at 40 for a purpose, which will be hereinafter more fully described, while the outer face of the anvil is provided with a seat 41 forthe reception of the eyelet 36 of the button 27.

In order to hold the button in position and the eyelet in alinement with the arcuate face 39 of the anvil a holding spring 42 is provided. This spring 42 is of a U-shape in cross section and embraces the flattened faces 34 of the plunger. The extreme lower end of the spring 42 is provided with inwardly directed spring fingers 43 for gripping the eyelet and holding the same in the seat 41. The forward front edges of the sides of the spring adjacent to the upper or inner end thereof is provided with outturned resilient lugs 44 the purpose of which will also be hereinafter more fully described.

The spring 42 is held against displacement by means of a pin 45 which extends transversely through the plunger and the sides of the spring 42. The terminals of the pin 45 extend beyond the opposite faces of the plunger and forms a bearing for the operating arm 46, as will now be described. v

The operating arm 46 has its inner end bifurcated to provide a yoke 47 which straddles the depending leg 21 and the yoke is pivotally connected to the leg 21 ata point intermediate its ends by a suitable pivot pin 48. The extreme forward end of the yoke 47 is notched as at 49 for resting on the terminals of the pin 45 and the bifurcated portion 47 engages the resilient lugs or lips 44 of the spring 42 and these lugs or lips normally exert a tension thereon so as to prevent any lost motion between the operating arm and the plunger. The outer end of the arm 46 is provided with a suitable manipulating handle 50.

An expansion spring 51 is coiled about the plunger 17 and is confined between the sleeve 16 and a head 52 formed on the outer end of the plunger. This spring functions to normally hold the plunger and anvil in a raised position.

In connection with the plunger 17 I have provided a novel ejector 53 which forms one of the main features of this invention. This ejector 53 comprises an ejector arm 54 rockably mounted on a pivot pin 55 carried by the arm 15 adjacent to the sleeve 16. The arm 15 at this point is slotted as at 56 to receive the ejector arm 54 and the upper end of the ejector arm is provided with a cam head 57. This cam head is normally re ceived within a longitudinally extending groove 58 formed in the plunger 17 and the inner end of the groove is provided with an inclined face 59 for engaging the head 57 and actuating the arm as will be later described. The lower or inner end of the ejector arm 54 is provided with an arcuate kicker foot 60 the purpose of which will also be hereinafter more fully described.

It is to be noted however that when the plunger 17 is being moved inwardly that the inclined face 40 of the plunger will engage the arcuate foot 60 and move the foot out of the path of the plunger. I/Vhen the plunger is in its extreme raised position the inclined wall 59 of the groove 58 formed in the plunger 17 will engage the cam head 57 IUU of the ejector and swing the ejector'on its pivot 55 for moving the kicker foot directly under the anvil or lower end of the plunger as clearly shown in Figure 5 of the drawings.

In operation of the improved tool the fastener 25 is grasped and the disk shaped face 25 is slid into theseat 24 between the arms or resilientlegs 32 of the spring 28, after which the button is taken and the eye let 36 thereof slid into the seat41 between the clamping jaws or arms 43 of the spring 4:2. The handles 20 and 50 arenow' grasped in the ordinary manner and the plunger is placed over the leather where the button is to be applied. toward one another and the shank 33 of the fastener 26 will be forced through the leather and will engage first the straight face 38 of the'anvil and then the arcuate face 39 of the anvil. This will clinchthe shank and coil the same back and through the eyelet 36 of. the button. the shank is first bent before being passed through the eyelet 36 and when the shank The handles are now brought 3 It is to be noted that fastener 26 and force the fastener, the but ton and the leather out of the-tool. Thus it is obviousfthat theapplication of the tool i's considerably facilitated by the inclusion of the ejector, which as heretobe-e fore-stated forms one of the important featitreso'f 'the invention.
