longitudinal section, of an axle and its wheels asprovided with my invention. Fig. 3&8?
top view,and Fig. 4 a longitudinal section, of
the axle. Fig. of the wheels. I
On May 25, 1869, Letters Patent No. 90,410
5'is a transverse section of one Were granted to myself and Joseph H. Glapp on an invention made by me, the same mainly consisting in the combination and arrangement of two wed e keys, a, stop piece, and grooves in the wheel-hub and axle, the whole being substantially as exhibitedin the specification and drawings of .such patent.
My present improvement has particular reference to the stop-piece of such combination, which stop-piece I provide with a screw, to forceit backward as it may become worn.
The said stop-piece I make sometimes in one and sometimes in two pieces, the screw-shank in the latter case going through both parts, as hereinafter explained. WVhen made in two parts, the stop-piece admits of one or more washers or thin plates of metal being arranged between theparts and on the shank of the screw in case of wear of the stop-piece and of it being desirable to extend it-lengthwise at any time.
In the drawings, A denotes the axle, and B Bits two wheels; I) b, the wedge-keys; a a and 0 0, the grooves of the axle and wheel-hubs do hereby for the reception of the wed ge-keys. The stop pieces of the grooves of the axle and the wedgekeysare shown at c 0.
Between one of the inner wedges and its stop-piece is a capstanscrew, (1, which is screwed into the wedge, and has its headabutting against that end of the stop-piece which is next to the next adjacent wheel. 011 turningback the screw the wedge will be forced into the wheel, and the stop-piece will bepressed back against the inclined inner end of the groove to. series of holes made diametrically through it, to enablea person, by means of a pin, to revolve the screw as occasion may require.
The drawings also represent the screw at ward into the groove, and the wedge will be The stop.
driven forward into the wheel. piece may be made in one solidpiece; but in case it may be preferable to have it in two pieces, f f, as described, it may be so constructed.
I claim The combination of the" tightening-screw d or d, or its equivalent, wi'th'the wedgekeys b b, the grooves a 0, (in the wheel, hub, and
axle,)and the stop-piece a, substantially as described. I O I CHARLES DARWIN TISDALE.
