Its intended use is to rende-r the forc ing of a relatively large needle through two or more plies of canvas, leather or other material to tion. 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 ex be sewed together. In the prior art it has been the practice to employ protecting devices for workers’ hands tension neck or arm of the main body of the plate, co-planar therewith as shown at 3, is curved around to ñt the back of the index and middle fingers of the hand of the operator thereby as sisting 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 indi cates the metal insert, the exposed face of which is concave as shown in Fig. 2. wherein a relatively flexible pad was adapted to be engaged by the tool employed. In the pres ent invention a protecting pad is formed from substantially rigid material which will not ma terially deform in use and will añord a greater degree of protection for the user. . It is to be understood that by merely having In the embodiment herein illustrated this mem ber is shown applied to a sail maker’s 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 lim ite-d thereto. 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 in ' It is an object of the present invention to pro vide a single, practical and easily manufactured protecting device for the hands. ~ vention or the method of use. ' Another object is to provide a protecting de The operation of the device consists in grasp vice which is substantially non-deformable and ing it firmly in the hand. The thumb rests in notch 2, the back of the index and middle ñnger in notches yIl; the base of the fingers or the edge 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 pres ent invention is to provide means for engaging the end of a tool and preventing slippage thereof. f In the present invention the plate is so shaped as to be comfortably gripped and by reason of its peculiar shape is easily held between the thumb and lingers in a iixed position against the palm of the hand. The function of the tool engaging of the palm of the hand rests along curved sur face 5. The metal insert 6 is brought into con tact 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 gov ernmental purposes without the payment to me of any royalties thereon or therefor.
