s claims.V (cl. z-zo) (Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 O. G. 757) This invention relates to sewing devices and more particularly to a new and improved palm for the protection of the hands during sewing operations. Its intended use is to rende-r the forcing of a relatively large needle through two or more plies of canvas, leather or other material to be sewed together.

In the prior art it has been the practice to employ protecting devices for workers hands wherein a relatively flexible pad was adapted to be engaged by the tool employed. In the present invention a protecting pad is formed from substantially rigid material which will not materially deform in use and will aord a greater degree of protection for the user.

In the embodiment herein illustrated this member is shown applied to a sail makers palm which serves to protect the hands during sail making or repairing operations. Of course other uses of the present invention will be apparent to persons skilled in the art and it is not desired to be limite-d thereto.

It is an object of the present invention to provide a single, practical and easily manufactured protecting device for the hands.

Another object is to provide a protecting device which is substantially non-deformable and will afford maximum protection.

Still another object is to provide a hand pro- .y

tecting palm which is readily formed fromv rigid sheet material which will be light and strong in construction.

Another object of one embodiment of the present invention is to provide means for engaging the end of a tool and preventing slippage thereof. f

those parts in contact with the thumb, iingersy and palm, rounded for the comfort of the operator. A metal disc of lead, aluminum, brass or the like relatively soft metal is inserted therein. The insert is concave in its operating face in order to prevent the needle from slipping to one A side when pressure is exerted.

These various features are illustrated in the accompanying drawing in which:

Fig. 1 is an elevation of the device, and

Fig, 2 is a section taken along section line 2-2 of Figure 1 partly in elevation and partly in section.

In Figs. 1 and 2, the plastic plate is represented by I. This plate has a curved notch for the thumb of the operator cut out as at 2. An extension neck or arm of the main body of the plate, co-planar therewith as shown at 3, is curved around to t the back of the index and middle fingers of the hand of the operator thereby assisting in holding the device in position. At 5 is shown the curved edge o-f the plate which lits along the inside surface of the lingers. 6 indicates the metal insert, the exposed face of which is concave as shown in Fig. 2.

It is to be understood that by merely having the metal insert project to either the front or rear surface of the body plate determines whether the device is for right or left handed operation. In the embodiment as illustrated the device is for right handed operation.

Various changes inthe shape of the device may be made without affecting the function thereof or without departing from the spirit of the invention or the method of use.

The operation of the device consists in grasping it firmly in the hand. The thumb rests in notch 2, the back of the index and middle nger in notches yIl; the base of the fingers or the edge of the palm of the hand rests along curved surface 5. The metal insert 6 is brought into contact with the head of the needle and the latter is easily forced through the material to be sewed.

This invention may be made or used by or for the Government of the United States for governmental purposes without the payment to me of any royalties thereon or therefor.

What is desired to be secured by Letters Patent of the United States is:

1. A hand sewing device for protecting the hands during sewing operations comprising a body of substantially non-deformable plastic material adapted to be grasped by the user, said a body having an integral, co-planar finger fitting portion extending therefrom.

2. A hand sewing device for protecting the hands during the sewing operations comprising a body of rigidplastic material, and a metallic insert in said body, the whole being adapted to be grasped by the user and said body having an integral, co-planar finger tting portion extending there-from.

3. A hand sewing device comprising a plastic plate including a metallic disc inserted therein,

said plate having an integral, co-planar iinger fitting portion extending therefrom.

4. A hand sewing device comprising a rigid plastio plate including a relatively soft metallic insert therein, said plate having an integrals coplanar finger tting portion extending therefrom.

5. A handsewing device adapted to function -as a thimbleto force ya needle through material being sewed comprising a plate portion adapted to t the palm of the hand; a portion, integral and co-planar with the plate, extending therefrom to the back of the fingers, adapted to t the backs of certain of the fingers and a relativelysoft metallic disc inserted in the plate adapted to impinge Yfingers and a relatively soft, concave metallic disc inserted in the plate adapted to impinge upon the'needle in forcing it through the material beingsewed.
