RESILIEN'I surronr roa PLASTERERS HAWKS.

. Application' filed March 25, 1920. seriai'uo. 368,772

T 0 all whom it may concern:

Be it known'that I, ERNEs'r J. PEOK, a citizen of the United States, and resident of Portland, county of Multncmah, State of Oregon, have invented a new and useful Improvement in Resilient Supports for Plasterers Hawks, of which the following is a specification.

My invention relates to means for preventing the constant pressure imposed by the weight of the material carried by the plasterers hawk on, the muscles of the hand, causing callouses, soreness and undue fatigue. r e

Heretofore various pads for the hands have been tried, but I found in my experience as a practical plasterer, that. they are not suitable, generally because not remaining in an efficient state for any length of time, and furthermore, not giving that softness and elasticity which alone will relieve the stress on the muscles of the hand.

The object of my invention is to provide an efficient hand-rest or cushion for the hawk, and which, besides, is inexpensive to make, comparatively, and easily applied.

I attain my object in removably mounting on the handle of the hawk, an annular pneumatic hand cushion, which furthermore, has the special features hereinafter set forth and illustrated in the accompanying drawing in order to render my invention practical for manufacturev as well as for use.

In said drawings, Figure 1 shows aside elevation of one mode in which my invention is carried into practice;

Fig. 2 is a horizontal section relating to the device shown in Fig. 1, but on a larger scale than the latter; Fig. 2 being taken on the line 2 of Fig. 1, looking in a direction indicated by the arrow; and

Fig. 8 illustrates another mode of carrying my invention into practice.

The hawk may be made of any convenient construction except in the particulars hereinafter stated.

Referring first to Figs. 1 and 2: The table a, has a piece I), dove-tailed into it. In said piece I), is housed a socket c, in which is threaded the stub-screw d, of the'handle e. f is my pneumatic hand cushion. It consists of a hollow annular casing f preferably made of rubber fabric, and is adapted for inflation by a valve 9.

The valve may consist of a piece provided with orifice h, and having on the 1n- Specifieation of Letters latent.

, clearly in Patented Aug. 3,

terior flaps z', 2" adapted to be firmly pressed together by the pressure within the'hollow casing; thus preventing the escape of air from the hollow casing, at the same time permitting the inflation of the casing by the mouth, or a pump.

The valve s positioned on an oblique plane with respect to the horizontal, so as to avoid its coming into'contact with the hand, even though the hand-cushion be only slightly inflated in order to have it very soft and resilient. The degree of inflation is thus left to the judgment of the user of the hawk. The handle 6, adjacent the underside of the table a, is provided with a slight peripheral concavity, as at 7', so as to firmly seat the cushion. The cushion is first inflated and then moved into place on the handle.

The type of hawk shown in Fig. 3 is assumed to be the same construction as shown in Figs. 1 and 2; although of course such details are immaterial to my invention.

My cushion as illustrated in Fig. 3, consists of a circular web 70, provided with a central hole'so that it may be slipped over the handle 9, of the hawk; the handle being provided with a peripheral groove adjacent the underside of the table as shown at Z. m is my pneumatic hand cushion. In this case it consists of a hollow rim m formed integral with the web is. The whole is constructed of rubber fabric. The diameter of the central hole in the web 70, is slightly less into place, the web 7: will cup, and in so doing firmly hold the cushion against the underside of the table, as illustrated more the sectional side of Fig. 3.

The same construction also facilitates the removal of my cushion. After forcing the rim. of the hand-cushion down away from the underside of the table, the cup will be inverted and therefore facilitate the removal of the hand-cushion from the handle.

The hollow rim m is provided with a valve a, similar to the valve g, shown in the Figs. 1 and 2 of the drawings.

My pneumatic cushion-evenly distributes the pressure on the muscles of the hand, and p in so doing relieves any severe stress on some portions of the hand only. the weight it is rendered more bearable. My pneumatic hand-cushion is adapted to do By distributing thisbecause itmay adapt itself to all the unevenness in the surface of the hand on which the table of the hawk rests. A mere pad or less yielding and flexible hand-rest will not answer the purpose.

I claim:

1. A hand-cushion for hawks consisting of an annular hollow body provided with a valve for inflation, said valve being located in a plane oblique to the horizontal for the purpose specified.

2. A hand-cushion for hawks, consisting of a circular web made with a hollow rim, the web having a central hole for slipping over the handle of the hawk, a valve in said hollow rim.

3. A hand-cushion for hawks, conslstlng of a clrcular web made with a hollow rim,

. the web having a central hole for slipping over thehandle of the hawk,

the central hole being of lesser diameter than the cross'section of the handle of the hawk, on which it is to be mounted thereby causing the cupping of said web as described, a valve in said hollow rim.

4. A hand-cushion for hawks, consisting of a circular web made with a hollow rim, the web having a central hole for slipping over the handle of the hawk, the central hole bein of lesser diameter than the crosssection of the handle of the hawk, on which it is to be mounted thereby causing the cupping of said web as described, a value in said hollow rim, said valve planefobliqueto the horizontalfor the purpose specified.
