SPOKE-TENONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 256,897, dated April 25, 1882.

Application filed December 5, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHRISTIAN B. HOLMES, of the town of Urbana,in the county of Champaign, in the State of Ohio, have invented a new and useful Machine for Tenoning Spokes; and I do hereby declare that the following is a full, clear, and exact description of the construction and Operation of the same, reference being had to the annexed drawing, making a part of this specification.

Myinvention relates to spoke-machines; and it consists in details of construction that will be hereinafter more fully set forth in the specification and claim and pointed out in the accompanying drawing, which is a perspective view of my device.

Referring moreparticularly to the drawing, A represents a horizontal plate or bed having at one end the spoke-rests (t o and an intermediate spoke-clam-p, b. The rests a a are preferably cast or made in one-piece with the bar A. The spoke B is passed through the.

clamp b and held firmly by tightening up the tail-tap c, which is screwed on the shank or projection b of the clamp. At the opposite end of the bed, and at suitable distances apart, are two clamps, D D, whose shanks pass through the bed and are held in position by suitable set-screws, 0 e5. These clamps hold socurel y an au ger-sh aft, F, having a shoulder, G, upon which rests one end of the feed-lever H, the opposite end of said lever being slotted and attached to the hand-lever K by a pin, L. This hand-lever K is attached to the upper clamp, D. A hollow anger, R, is attached to one end of shaft F, and a crank-arm, 0, held by a set-screw, P, is attached to the other end of the shaft. On said shaft, between the crankarm and clamp D, is asliding gage, N, held in any desired position by a set-screw, Q. By means of this gage the movement of the shaft F and anger in the boring direction is limited, and therefore thelength of the tenon may be accurately determined. When the boring is completed the shaft F and anger are thrown back by the lever K, the clamp b unclamped, the spoke removed, and the machine is again in readiness for another spoke.

Thus it will be seen the operation is simple and quickly done, and as the several parts of my device are light and preferably made of have hereunto set my handt-his 15th day of November, 1881.

CHRISTIAN B. HOLMES.
