CUSHION HEAD FOR STAPLING DEVICES AND THE LIKE Filed Sept. 25, 1945 2 Sheets-Sheet 2 CHE-L E. HQLLEN INVENTOR.

Patented Mar. 22, 1949 NITED STATES CUSHION HEAD FOR STAPLING DEVICES AND THE LIKE Carl E. Hallen, Mount Prospect, Ill., assignor to J. B. Crofoot 0.0., Mount Prospect, Ill., a corporation of Illinois 6 Claims.

This invention relates to cushion heads for stapling devices and the like, adapted to be struck by the hand or fist to operate the same.

More specifically, the invention relates to the provision of improved means for joining a cushion head to a stapling device.

I have found that by my invention, improved means are provided for joining a cushion or flexible rubber capto the head of a stapling or other device, which is struck by the hand or fist to operate the same, in order to soften the blow.

I have shown two alternate forms of joining means. In one form, I have shown a plate, adapted to be secured to a disc, which, in turn,

is adapted to be located in a recess in a cushion cap.

The disc is adapted to hold the plate to the cap, while prongs are adapted to be bent around the stapling head to hold the cap to the stapling head.

In another alternative form, I have shown a cushion cap, having a somewhat different recess, and an insert located in said recess, which insert is adapted, in turn, to be mounted upon a stapling head to secure the cushion cap to the stapling head.

In this second device, no metal is used at all in the means for securing the cushion cap to the stapling head.

Heretofore, in application, Serial No. 495,634, filed July 21, issued on January 29, 1946, as U. S, Letters Patent No. 2,393,769, I have shown a plate for coup-ling the cushion or cap to the stapling head.

Another object is the provision of means for the 1 foregoing, which will be reasonable in cost and simple and effective in operation.

Further objects and advantages will appear and be brought out more fully in the following specification, reference being had to the accompanying drawings, in which:

Fig. 1 is an elevation of the cushion cap united to the stapling head by the joining means of my invention.

Fig. 2 is a perspective view of the plate used in joining the cap to the stapling head.

Fig. 3 is a vertical section through the cap and the joining means, to wit; The felt disc and the plate.

Fig. 4 is a view illustrating the means by which the felt is attached to the metal plate.

Fig. 5 is a top plan view of the plate.

Fig. 6 is a view of the alternative device, shown half in elevation in full lines and half in section.

Fig. 7 is a vertical section.

Fig. 8 is an elevation,

Fig. 9 is a vertical section of the insert.

Fig. 10 is a section of the cushion cap alone.

Fig. 11 is a bottom View of the insert; and

Fig. 1.2 is a bottom view of the cushion cap.

Referring to the drawings, I have, in the first form, illustrated a device having a cushion cap it, with shoulders llla, provided with a cylindrical recess H, with sides lla, Nb and H0, in which is felt disc 52, with sides is and M.

The felt disc is adapted to be secured to a circular plate it of metal, preferably spring sheet metal, plastic or the like, of a concavo-convex formation, having a turned flange or edge l6 downwardly extending at right angles, so as to lit the periphery of the head H.

The plate is formed with suitable, and preferably equidistantlyspaced, lugs is projecting from the edge it, so as to be bent under the head I! to retain the plate in position on the head.

The plate is also provided with a plurality of pointed tongues or tapered prongs l9, also preferably placed equidistantly and struck out from the body or metal of the plate to form tapered or triangular cut-outs lilo, when the tongues have been struck out.

The cut-out portions extend axially, as shown in Fi 5.

The plate, by means of the prongs, is adapted to be secured to the layer of cloth, such as felt, or other similar cushion or pliable material.

The felt is adapted to be pierced under pressure by the tongues 53, as shown in Fig. 3.

The ends of the tongues are bent over, as shown in Fig. 4, to securely attach the felt layer or disc to the convex side of the plate.

It will be understood that other similar material, such as fabric, may also be used, and any number of layers may be employed to give the proper thickness,

It will be understood that the layer of felt will be tightly compact, and, after the felt has. been attached to the plate, the felt will be inserted in the recess ii in the cap or cushion Ill.

It will also be understood that the top of the cushion head may be made of rubber, and may have its top surface continuously rounded so as to conform to the palm of the hand, when struck by the hand.

It will be at once apparent that I have provided a device whereby the rubber cushion or cap will be securely held on the head by means of the arrangement of the felt disc in the corresponding recess in the cushion head, and by the arrangement of the plate and its prongs for attaching the 3 felt to the plate, and the tongues l 8 for attaching the plate to the stapling head.

I have shown an alternative form of means for joining a cushion head to a stapling device. I have shown a cushion cap 20, adapted to be struck by the hand or fist to operate the same.

The cap has an enlarged recess 2| and a. reduced recess 22, the enlarged recess 2| being formed by sides 23, 24 and 25, and shoulders 24a and 25a; the reduced recess to be formed by the sides 26 and 21.

Adapted to be received in this recess, is a joining element 28, adapted to join the cushion cap to the stapling head, shown fragmentarily in Fi 6.

The joining element 28 may have a flat top 29, somewhat vertical sides 30, and shoulders 3|.

The joining element may be provided with a recess 32, for the staplin head, and a circular inturned flange 33, adapted to fit under the stapling head to hold the joining element on the stapling head.

These parts may be made of molded rubber, for example.

The cap 20 may be molded with a recess in it, as described, and the joining element will fit within the recess in the cushion cap, and be held securely by the cushion cap.

The joining element, in turn, may be mounted on the head, and all the parts securely held thereon.

The side 29 of the joining element will abut the inside surface 23 of the cap, and the sides 30 of the joining element will register with the sides 24 and 25 of the recess of the cap.

The shoulders 3| of the joining element will abut the shoulders 24a. and 25a of the cap, to lock the parts together.

In both forms of the invention, the stapling head is substantially completely outside the confines of the cushion head when the latter is assembled with the stapling head. The result is that both assembly and disassembly are facilitated, and the cushioning qualities of the cushion head are not impaired by the presence of a rigid, unyielding stapling head within the cushion head.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variation and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a device of the kind described, the combination of a cushion cap and means for securing the cushion cap to a stapling head; said cushion cap having a recess in its underside; said securing means having a first part which fits in said recess and interlocks with the cushion cap without affecting substantially the cushion quality of the cushion cap, and having a second part which projects below the underside of the cushion cap and provides for receiving the stapling head substantially outside the confines of the cushion p, said second part including means for quick ttachment in holding engagement with said h d and quick detachment therefrom.
