Letters Patent No. 84,077, dated November 17, 1868.
IMPROVEMENT IN THILL-COUPLING.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern .1
Know ye that I, VVILLIAM WALLAcE Annnnson, of the city of Camden, county of Camden, and State of New Jersey, have invented a Shaft or Pole Coupling, being a new and useful improvement for attaching the shafts and poles of vehicles thereto; and I do hereby declare the following to be a full and exact description of my said invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, like letters indicatinglike parts.
To enable others skilled in the art to make and use my invention, I proceed to describcits construction and operation.
My invention relates to attaching to'the lower side of the rear end of a shaft-iron, when secured to a shaft by ordinary methods, a steel spring, which is bolted to the shaft-iron and shaft. The spring acts towards the lower surface of the former, and is opened by a screw working upon a thread in a hole in the spring, near the end thereof. This screw has a shoulder below and a head above, and between the shaft-iron and shaft, so.
ner that the lesser curve in it rests upon the shaft-pin.-
By the action of the spring, the segment at its end is brought up so that the lesser curvethereof fits upon the lower side of the shaft-pin, which is thus almost entirely encompassed by the two segments, and forms an axle upon which the partial cylinder works.
The two segments are provided with lips on their rear portions, which curve, the upper upward and outward, the lower downwardand outward, to form an opening for admission of shattpiu. These segments do not touch each other, but only the shaft-pin. This is so arranged in order that the spring-may exert a steady pressure upon the shaft-pin, preventing rattling or detaching of shaft without requiring the pressure which may be obtained by using the screw.
In the drawings hereto'annexed. and made a part of this specification- Figure 1 represents a side elevation of a portion of .a shaft, with spring b attached.
Figure 2 represents a central vertical section through the line :u-x, fig. 3, showing shaft-box, fig. 3, attached to axle It, by means of ordinary clip, on; also, thcposition and operation of screw (0, and method of attaching shaft n to shaft-irony, by the bolts 0 0.
Figure 3 represents a plan view of shaft-box, showin g shaft-pin g.
Operation.
To attach shaft, by means of the screw a, open the spring I), pass the arch E, at the end of the shaft-iron f, over the shaft-pin g. Turn the screw to in a reverse direction to first movement, which brings the concavity in the arch d, at the end of the spring b, directly against enclosed in a hollow cylinder, the upper and lower parts of which do not meet. By this fact, the pressure is upon the shaft-pin 9 alone, and rattling as well as detaching is prevented, as the screw a operates only to open the spring I), but may be used if greater pressure upon the shaft-pin g is required.
To detach the shaft, throw open the spring 11, by means of the screw (4. The shaft may be then readily removed.
In the construction of my invention, any metal possessing strength and elasticity may be used, but for the springb, and the shaft-pin g, steel is preferred.
7 What I claim as my invention, and desire to secure by Letters Patent, is-
The steel spring I), in combination with the segments or arches d and E, which bear upon the shaft-pin 9, but do not touch each other, and withthc screw-bolt a, the whole arranged and operated substantially as and for the purposes herein set forth.
