` HAND Pnn Fon PLASTERING TROW'ELS.

Application lfiled June 24,

My invention relates to plasterers.' tools and more particularly to a plastering trowel with a hand-pad attached thereto.

Plasterers and other users of plastering trowels find that the constant .gripping of the handle of the trowel, together' with the constant pressure necessarily exerted on the trowel agaist a. wall or ceiling, for hours at a time, fatigue the gripping-muscles of the hand and the muscles of the fore-arm as well as the wrist to such an extent as often to cause considerable discomfort and even distress.

The primary object of my invention is to provide a plastering trowel, equipped with a flexible hand-pad against which pressure may be exerted by the back of the hand so as tol relieve the gripping muscles and the strain on the wrist, at times, thus affording them intervals of Comparative rest.

A further object is to provide a flexible hand-pad, for use on plastering trowels and the like, which is simple, durable and inexpensive and which readily may be attached to the trowel or removed therefrom.

Other objects and advantages will appear hereinafter' and while I show herewith and will describe a preferred form of construction, I desire it to be understood that I do not confine my invention to such preferred form but that various changes and adapta.- tions may be made' therein without departing from the spirit of my invention as hereinafter claimed.

Referring to the drawings which accompany this specification and form a part thereof,

Fig. 1 is a view in perspective of my im* proved plastering trowel equipped with my flexible hand-pad.

Fig. 2 is an enlarged transverse sectional view of the trowel shown in Fig'. 1, taken in a plane through the middle of the handpad and looking toward the handle post.

Fig. 3 is a longitudinal sectional view of the hand-pad, by itself, taken on line 3-3 of Fig. 2.

Considering the drawings more in detail it will be seen that the trowel, vin common with all plastering trowels, consists of a thin rectangular blade 1() having a handle post 11 attached at right angles thereto| by a fastening-strip 12, made integral with the y handle post, said fastening-strip extending 1926:- seriai No: 118,144.'

longitudinally in the middle of the blade and being riveted thereto, and saidrpost be ing provided with a shank 13, fixed thereon so as to be parallel to the blade and fastening-strip and cor-extensive with one end of the latter. A handle 14 of wood or other suitable material is mounted on shank 18 and is held thereon by a nut 15 in the usual way. As shown in Fig. 1 the handle is made somewhat thinner in the middle than at the ends, so that it is slightly concave in longitudinal outline, to provide a more reliable grip for the hand than the usual straight form.

That part of fastening-strip 12 which extends parallel to the handle in spaced rela.- tion thereto, is made of a relatively thick bar 16, with Vshaped grooves 17 cut in its sides, so that it serves as a slide-rail upon which the pad, presently to be described, is mounted. The pad 18 is preferably made of soft rubber or similar flexible material. Its length is about Vequal to that of handle let and it is approximately elliptical in cross section. A longitudinal groove 19, fitting rail 16, is formed in the under side of the pad, whereby flanges 2O are produced which lit in V-shaped grooves 17 of said rail. Transverse depressions 21 are formed on the Lipper side of the pad, giving it a wave-like outline adapted to conform to the lingers of a closed hand when grasping the handle.

Reinforcing clips 22 of spring metal, bent to coincide with groove 19 are moulded into the pad at the middle and ends thereof, as shown in Fig. 3, or a full-length metal strip, similarly bent, may be used instead of the clips shown.

The pad thus formed is adapted to be slipped endwise onto rail 16, as Vshown in F ig. 1, and in this position serves as a pressure pad for the back of the hand, there being ample space left between the handle 17and the pad 18 to permit of fingers being inserted therein as indicated by the dotted lines in Fig. 2.

The use of the pad is evident. `When the blade 10 of the trowel is pressed against a wall or ceiling, in the usual way, the grip of the hand on handle 14 may be relaxed occasionally andA pressure applied against pad 18 by the back of the hand or fingers, thus shifting the muscular strain and resting the gripping muscles and Wrist, so that the sense of discomfort due to fatigue, in the course of a days Work will be much reduced.

Hl ving thus illustrated and described my invention, I Cla-im:

1. A hand-pad, for use on plastering t-roWels7 Comprising an elongated body of flexible material having a longitudinal groove in one side thereof and transverse reinforcing clips, conforming to said groove, whereby said body may be detachably fixed to the blade of a plastering trowel under the handle thereof.

2. A plastering troWel equipped with a hand-pad, said plastering trowel having a mountingbar fixed under the handle thereof and said hand-pad comprising an elongated body, (2o-extensive with the handle of the plastering troWel, of flexible material said body having a longitudinal groove in one side thereof fitting on said mounting-bar, whereby said hand-pad is detaehably held on the trowel in spaced relation to the handle thereof.
