CRUTCH PAD.

Application mea January 26, 1925. serial No. 4,669.

To all whom 'it may concern:

Be it known that I, CHRISTIAN MOORE, citizen of the United States, residing at Akron, in the county of Summit and btate have invented new and useful Improvements in Crutch Pads, `of which the following is a specification.

This invention relates to crutches and has particular relation to a new and improved crutch pad for the arm pieces thereof.

Objects of the invention are to provlde a durable pad for the arm piece of a crutch which may be quickly and conveniently secured thereto and which will maintain itsI shape and cushioning qualities after a long period of use and which may be manufactured at a low cost and will be extremely efficient in use.

Other objects are to provide an elastic sheath for the arm piece of a crutch and to have incorporated therein elastic cushionin means and to thereby provide a crutch pa which may be used on arm pieces of different sizes and which will be securely retainedon the arm piece by the elasticity of the material of which it is composed.

Other advantages are to provide a sanitary crutch pad of attractive appearance which may be conveniently removed and washed or otherwise cleaned and which may be easily applied to an arm piece without the use of lacings or clips to hold the same thereon.

The above objects are accomplished and additional ends are attained by the novel construction, combination and arrangement of parts hereinafter described and illustrated in the accompanying drawing, wherein I have shown a preferred embodiment of the invention, it being understood that the invention is not to be limited to exactly conform to the details of construction shown, but that changes, variations and substitutions may be made which come within the scope of the claims hereunto appended.

In the drawings in which similar characters lof reference are employed to designate/y like parts as the same may appear in any/ of the several views Figure 1 is a side elevational view of a crutch equipped with a crutch pad constructed in accordance with this invention.

Figure 2 is a cross sectional view of the arm piece of a crutch with a .crutch pad constructed in accordance with this invention secured thereon, the same bein taken as indicated by the lines 2-2 of Flgure 1.

Figures 3 and 4 are similar, sectional views, each showing a modified form of the invention.

Figure 5 is a central, vertical, sectional view of a crutch arm piece equipped with a crutch pad constructed in accordance with this invention.

In the drawings, the numeral 5 is used to denote acrutch and the numeral 7 the arm piece thereof. The pad of this invention is preferably constructed entirely of rubber and comprises an inner wall or sheath of elastic rubber which has a cavity 9 adapted to receive the arm piece of a crutch. The sheath 8 is preferably formed smaller than the arm piece and is placed thereon in a stretched condition so as to be retained in place by the elasticity of the material. The outer wall 10 of the pad is preferably formed integral with the sheath 8, the same being vulcanized thereto at the sides and ends of the pad so as to form a pocket which is filled with sponge rubber 11.

The crutch pad may be constructed by placing the sheath 8 on a form, then placing the sponge rubber pad 11 on the upper face of the sheath 8 and then covering the sponge rubber pad 11 with the outer cover 10 and adhesively uniting the edges of the cover 1.0 to the sheath 8; or sponge rubber 11 may be placed between the unvulcanized cover 1() and the sheath'8 in the form of unvulcanized rubber compound containing a blowing element and the article is thus built up, placed in a moldand vulcanized, the blowing element forming the sponge rubber cushion 11 during vulcanization.

In the modification shown in Figure 3,v the reference character 7a is used to denote the crutch handle, the numeral 10 denotes a rubber sheath and the numeral 11 a sponge rubber pad which is vulcanized or otherwise secured in the sheath 10. The sheath 10 is provided at each edge thereof with a fabric insert 10b and is additionally secured to the arm piece 7a by nails, tacks or other fastening means 12. The modification shown in Figure 4 is similar, the sides of the sheath 10 being made of suicient length to overlap on the underface of the arm piece 7 a so that they can be secured in nails or other fastening means 12.

It will thus be seen that I have provided an extremely ei'icient crutch pad which 1s composed entirely of elastic material and which may be readilystretched to fit a plurality of sizes of arm ieces and that the crutch pad may be uick y and conveniently" attached or remove from a crutch.

Having thus described my invention what I claim as nevi7 and desire to secure by Letters Patent is l. In a pad of the class described, an elastic sheath adapted to fit over the arm piece of a crutch and a sponge rubber cushion in said sheath.

2. In a pad of the class described, an elastic sheath adapted to fit over the arm piece of a crutch, said sheath provided with a pocket and an elastic cushion in said pocket.

In a pad for a crutch arm piece, an integrally formed elastic sheath havin incorporated therein a sponge rubber cus ion.

4. In a pad for a crutch arm piece, an elastic sheath having a cavity normally smaller than the arm piece the said sheath adapted to be fitted over said arm piece in a stretched condition and be retained thereon by its elasticity and a cushion in said sheath.

an elastic sheath, said sheath having an.

inner and outer Wall and a sponge rubber cushion betweenV saidwalls.

8. A' pad of the 'class described, including. an elastic sheath adapted when in a stretched condition to be fitted over the arm piece of a crutch, said pad provided on its upper face with integr-allyformed inner and outer walls and a sponge rubber' cushion positioned between said walls and vulcanized thereto. i

In testimony lwhereof I have hereunto set my hand. l' i CHRISTIAN MOORE.
