Improvements in Pads for Crutches, Sticks, and Wooden Legs. I William Harold Glover of 24 Brundrett’s Road, Chorlton-cum-Hardy, Manchester, in the County of Lancaster, Wood Engraver, do hereby declare the nature of this invention to be as follows :— My said invention relates to improvements in pads for crutches, sticks and •5 wooden legs and relates more particularly to pads intended to be anti-slipping. At present the most generally used crutch pad consists simply of a rubber sock forced upon the end of the crutch and having a sufficiently thick sole to produce the required softness and resiliency. This however, is in other respects most defective, inasmuch as it slips on wet or greasy surfaces and is either very quickly 10 pierced at the base by the end of the crutch, or burst at the sides, such bursting being caused by the stretching of the pad in a sidelong direction when the user is traversing uneven ground. This necessitates a frequent renewal of the pads which is a considerable source of expense. 15 My invention is intended to obviate these defects. For instance to prevent pads of this description from slipping I combine with the rubber metal or other suitable substance harder than the rubber. A con¬ venient way of doing this is to thrust or introduce steel or other metallic pins into the sole or foot of the rubber pad the heads of the pins lying about flush with the '20 rubber. These metallic pins are embedded in the solid pad about two thirds of its length, the impenetrated portion affording a soft and resilient cushion. The pins might be headed or staple shaped. The exposed ends of the pins acting in conjunction with the rubber foot grip the surface even when wet or greasy, and so prevent accidents. -25 AY hen traversing dry, smooth, or hard-frozen surfaces the rubber becomes the non-slipping agent so that between the two, all slipping of the pad is prevented. The pins inserted as above confer a certain amount of rigidity on the pad and prevent sidelong movement. I do not however confine myself to the use of steel pins or the like for the purposes of my invention as any other suitable arrangement -30 and any other material harder than rubber might be used. My invention also refers to an improved mode of securing such rubber pads whether anti-slipping or not to the crutch, sick or wooden leg. I furnish the foot of the crutch or stick with a ferrule of steel or other suitable metal and prolonged past the wood so as to present a hollow socket. I make a pad of solid rubber and fix the upper end -35 into this socket the socket therefore surrounding and supporting the pad so that all sidelong motion is prevented. There is little or no strain on the pad and it is not subject to be cut, burst or injured as under the ordinary circumstances. The pad fitted in this improved manner may be of my improved construction viz. with metal pins or other hard material combined with the rubber, or it might be of 40 rubber alone. When the pad enclosed in the socket is furnished with anti-slipping pins as described, the pins in conjunction with the socket confer such rigidity on the pad that all sidelong movement is prevented.
