FREDERICK WILL/AM UTTMER Patented Nov. 6, 1945 UNITED STATES PATENT OFFICE RIVETERS HAND PAD Frederick William Ottmer, Union City, N. J. Application September 30, 1944, Serial No. 556,605

2 Claims.

My invention relates to heat resisting pads, more particularly to pads to be worn by riveters over the back of their hands to protect the knu'ckles from the heat of riveting die and the heat of the rivets and plates.

Hand shields for riveters now on the market take the form of a glove portion covering the thumb and those fingers which are liable to come into contact with hot metal. When these shields are made of durable heat resisting material, they are very heavy and cumbersome, restricting the operator while intermittently using a chipping machine. Following the proposed method of practice, a riveter operates his riveting machine with his right hand using his left hand resting on the work as a guide and his chipping machine with his left hand. This makes it necessary that the fingers of the left hand be free to operate the trigger of the chipper.

The object of my invention is to produce a pad that will cover the back of the hand, protect the thumb and forefinger and at the same time leave the other fingers free to operate the chipper.

A further object is to produce a pad of the kind described that is economical in construction, flexible, so as to conform to the hand of the operator and still be durable to withstand rough usage. I propose to fashion the pad out of a flexible heat resisting material that has a low heat transference, one that is not readily destroyed by heat.

The foregoing and other features of my invention will now be described in connection with the accompanying drawing forming part of this specification in which I have represented my heat resisting pad in its preferred form after which I shall point out in the claims those features which I believe to be new and of my own invention.

In the drawing:

Figure 1 shows my riveters pad adjusted on the left hand of the operator.

Figure 2 shows the outside of the pad completely covering the back of the hand.

Figures 3, 4 and 5 show the shape of the blanks from which the pad is made.

In the carrying out of my invention I propose to use a blank of heat resisting material I I shaped to cover the back of the hand and wrist, provided with a slot I2 extending inwardly part way on one side to open and form the crotch between the thumb and forefinger.

Riveted and sewed to the blank I I is a layer of material I3 preferably of low heat transference material. The layer I 3 is substantially of the same outline as the piece I I but smaller in size.

Holes I4, l5, I6, I'I, I8 and I9 are punched in blank I I to accommodate rivets used in the assembly of the parts.

To form the thumb portion of the pad, I use an angular shaped piece 2|, one leg of the angle having an enlarged end 22 to form the gusset to close the crotch formed by opening the slot I2. The blank 2| is punched with holes 23, 24, 25 and 26.

In assembling these pieces, rivets are inserted in I4 and 24 and upset; in I5 and 23 and upset and in 26 and I! and upset.

The blank 3| is provided with holes 32 and 33. 32 is riveted to I6 of the main blank II and 33 is riveted to I5 and 23.

To hold the pad in place I provide straps 4I and 42, 4| being riveted to the apex of the angle portion at 25 and 42 is riveted to the main blank at I5. Buckles 45, 46 are fastened at I8 and I9 to the main blank.

I have discovered that an undressed leather known as pearl chrome is a most satisfactory material for the main blank II and while I am now using this material in the manufacture of my pads, I do not wish to limit myself exclusively to its use, because any soft flexible material with a low heat transference or any heat resisting material will be quite satisfactory.

The material of the appliqued blank I3 should be a hard tanned leather, to resist wear. I may puta layer of asbestos between the wearing piece and the main blank to further insulate the hand from the heat when desirable.

It will be readily understood that while I show the assembly of the blanks by rivets, this mode of fastening is not essential and I may choose to use staples or even sewing.

I wish it distinctly understood that my heat resisting pad herein above described and illustrated is in the form in which I desire to construct it and that changes or variations may be made as may be desirable without departing from the salient features of my invention and I therefore intend the following claims to cover such modiflcations as naturally fall within the lines of invention.

I claim:

1. A riveters hand pad comprising in combination, a blank of flexible material shaped to cover the back of the hand and wrist, said blank slitted to form an open angle and a thumb portion, an angular blank of flexible material, one leg of the angle piece enlarged to form a gusset and secured in the open angle in the back portion, straps attached to the apex of the angular portion and to the back portion whereby the pad may be held in place upon the back of the hand.

2. The device of claim 1 including a blank of flexible material extending from the enlarged leg of the angular member to the thumb portion of the back blank.
