SHAFT-COUPLING.
SPECIFICATION forming part of LettersvBatent No. 725,957, dated April 21, 1903.
Application iled August 2, 1902.
To all whom, t may conoci/'n.-
' Be it known that I, MARTIN HALFPENNY, a citizen of the United States, residing at Pontiac, county of Oakland, State of Michigan, have invented a certain new and useful Improvement in Shaft-Couplers; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains-to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to an improvement in' shaft-couplers for vehicles shown in the accompanying drawings, and more particularly set forth in thel following specification andclaim.
Referring tothe drawings, Figure lis a side elevation of the shaft-coupler, showing it engaged with the shaft and locked as it would be when secured to the buggy. Fig. 2 is a similar view showing it unlocked for the purpose of disengaging it from the buggy. Fig, 3 is an inverted plan view ofthe coupler.
Referring to the letters of reference shown on the drawings, Arepresents the shaft of a buggy or other vehicle; B, the shaft-iron,- which extends beyond the end of the shaft, terminating in an arc of a circle at B forthe purpose of engaging a rubber bushing C; sleeved on the bolt D,engaging the buggy.
B2 is a swinging arm pivoted at b, and likewise constructed on an arc of a circle, theconstruction being such that the parts B and B2 are adaptedV to completely encircle the bushing C when the part B2 is closed.
D is a lever pivoted at d to the lug b', formed integral with the swinging arm B2. At d' the lever is bent outward to forma convenient thumb-piece by which it may be oper- Serial No. 118,030. (No model.)
ated. The lever D is provided at its forward end with a raised portion d2, upon which the free end of the spring E bears.
E is a spring secured to the shaft-iron at d, the opposite end being free to bear against the end of the lever near its pivotal connection with the swinging arm.
The operation of the device will be readily understood from an examination of the drawings. To engage the shafts to a vehicle, the lever D is thrown down, so that the swinging arm may be open sufficiently to receive within its jaws the bushing C. The lever is then thrown up against the shaft-iron, the.move ment of which causes the jaws to close around the bushing, thereby engaging the shafts to ythe vehicle. The action of the spring serves to hold the locking-lever in position when closed. The bushing acts as an antirattler, and the connection between the shafts and the vehicle is such that play of the parts is avoided.
Having thus described my invention, what I claim is- In a shaft-coupler, the shaft-iron B, the fixed jaw B formed integral therewith, the
.swinging jaw B2 pivoted'to the fixed jaw and MARTINIIALFPENNY.
