I, Harry Jones of 94 Great George’s Street in the City of Belfast, Ireland, Cycle and Sewing Machine Mechanic do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly 25 described and ascertained in and by the following statement:— This invention relates to an improved crutch for the use of invalids and cripples and consists of a detachable pneumatic head, a stock of metal tubing or other suitable stuff with an adjustable handle and a self acting foot apparatus operated by the aid of compressed air. 30 The drawings filed with my Provisional Specification will enable my invention to be more fully understood the various parts thereof being separately lettered and thereby referred to in the following description. I construct the head of the crutch with an external wrapper or covering (A) of velvet or other cloth enveloping a canvas pouch (B) in which I place an air-tube 35 of india-rubber (C) and by means of a perforated, curved and flanged head plate (D) I fasten it to a curved and longitudinally corrugated steel frame (E) having a perforation preferably in the centre through which the mouth of the air- valve (G) passes and furnished near each end with a socket (F) brazed to it or stamped out by a die. The head-plate (D) is perforated to correspond with the -40 mouth of the air valve (G) and the sockets (F, F,) and is secured to the steel frame (E) by a milled nut screwed over the projecting mouth of the air valve. I run a wire band through a hem round the mouth of the canvas pouch and pass the steel frame into the pouch so that the wire band is held between the steel frame and the plate. 45 A cork lining may be placed between the wrapper (A) and the pouch (B) to preserve the air tube (C) from the effects of heat [Price 8^.] k , :
