TUBULAR METAL O'RUTCH.
SPECIFICATION forming part of Letters Patent No. 724,382, dated March 31, 1903.
Application iiled June 20, 1902.
To all whom t mfr/y concern:
Beit known that I, JOSHUA CONN, a citizen of the United States, residing at Dunkirk, in
ihe county of Chautauqua and State of New- `lessening the weight and strengthening the same. y
This invention also relates to certain details of construction, all of which will be fully and clearlyhereinafter described an d claimed,
is a detached plan view of the locking-collar.V
Fig. 5 is an enlarged detached bottom view of the block. Fig. 6 is an enlarged det-ached central vertical section through the rubber' cushion.
In referring to the drawings for the details of construction like numerals designate like parts.
The crutch-body is preferably formed of a light grade of seamless steel tubing, such as used in bicycle construction. In the preferred adaptation shown one piece of tubing is bent at the top to form the concaved arm part l, and two side portions or members 2 and 3 extend downward from said arm part and are slit and brazed together near their lower ends to form the single tubular lower part 4. A suitable transverse tube 5 is brazed in place between the side portions to constitute a hand-grasp. The lower extremity of Serial No. 112,408. (No model.)`
the part 4 is tapered and exteriorly screwthreaded, as shown at 6, and is provided with one or more slots 7. A tube 8, in which a spiral spring 9 is incased, is telescoped in the part 4. The tube 8 is moved longitudinally in the part 4 to lengthen or shorten the crutch and is locked in its adjusted position by tightening a screw-collar 10 on the screw-threaded slotted extremity 6. The upper extreme of .the tube S is internally screw-threaded, and a tubular screw-plug l1 is screwed into said eX- treme, against which the upper end of the spring 9 abuts, and the tension of said spring is varied by the longitudinal adjustment of the plug, said plug having one or more depressions 12 in its top edge for the reception of aturning implement. A rod 13, which may be hollow or tubular, if desired to lighten the construction, extends longitudinally within the spring and has its lower end screwed into a lower tube 14, the upper end of which engages against the lower end of said spring. This tube 14 is attached to the lower end of the rod 13 and has twosubstantially opposite longitudinal slots l5,into which the inner ends of screws 16 extend. The screws 16 pass through the enlarged lower end 17 of the tube 8. (See Fig. 2.) A block 18 is adjustably and detachably secured to the lower end of the tube 14, said block having a vertical internally-screw-threaded openin g l9,which screws on the screw-threaded vlower end of the tube 14 and is held in its desired position by alocknut 20. The opening 19 enlarges at or near the middle lportion of the block to constitute a depression or recess 2V1,and the walls of said recess are provided with an inwardly-extending shoulder or rib 22. A rubber cushion 23 is adapted to be sprung into the recess 21 and has a groove or depression 24, in which the shoulder or rib 22 seats. A spur 25 is also preferably screwed into4 the lower end of Ythe tube 1:4 and has a sharpened lower end which is adapted to project through an opening 26 in the cushion 23 when theblock 18 is screwed up sufficiently high on the tube 14.
The block 18 and cushion 23 may be attached, itvdesired, directly to the lower end of the tube 8,thereby dispensing with the spring.
The principal advantages of the inventiony reside in the increased strength and dura- IOC bility secured with a lghterand cheaper construction and the rigidity of the crutch against lateral or side strain,which is chieiy owing to the integral construction of the body.
I claim as my inventionl. A crutch-body ot a single piece of tubing' 4. A crutch having a tubular part, a tube telescoping in said tubular part, a spring in said tube, a rod tensioned by the spring, a second tube fastened to the lower end of the rod with its upper portion extending into the lower portion of the first-mentioned tube and having a longitudinal slot, and a screw or similar device extending through the rstmentioned tube and into thelongitudinal slot, substantially as set forth.
5. A tubular metal crutch having a tubular lower portion which is tapered screw-thread ed and slotted, a tube telescoping in said lower portion and longitudinally adjustable therein to lengthen or shorten the crutch, and alocking screw-collar on said lower portion, substantially' as set forth.
