GEORGE T. PEARSALL, 0F APALAOHiNyNEW YORK. Leam Patent No. 64,249, dated April 30, 1867.

IMPROVEMENT IN GARBIAGEPSHAGKLE.

TO ALL WHOM IT MAY CONCERN:

Be'it known that I, GEORGE T. PEARSALL, of Apalachin, Tioga county, in the State of New York, have invented a new and useful Improvement in Shackles for Carriages and other vehicles; and I do hereby declare that the following is a full and exact description of the same, reference being had to the annexed drawings, and to the letters of reference marked thereon, making part of this specification, in which Figure 1 is a longitudinal section. f Figure is a perspective View of the part attached to the thill or pole. Figure 3 is a perspective view of the part to be fastened to'the vehicle. Similar letters indicate corresponding parts in the several figures.

A is the shank of the part-attached to the thill or pole. O is the spur on the back part of the pintle I:

G is the shank of the portion fastened to the axle. E is the recess in which fits the spur C. I J are holes to the axle clip. F is the socket in which fits the pintle B Dis a piece of rubber or its equivalent to prevent;

rattling of the parts. H represents a section of the axle with section of shackle attached. The entering parts of the spurs C and recess D are made bevelling in order to force the end of the pintlc B hard against the rubber D in the bottom of socket F. The end of the pintle is hemispherical to enter the socket readily, and to.

make the most desirable bearing on the rubber D. The bottom of socket and rubber are of corresponding shape:

Operation.

To attach the thills or pole tothe conveyauce, it is only necessary to raise either in a nearly vertical position, enter the pintles in their sockets, and drop them in position for use. The bevel edges of the spur force them hard down on the rubber. To detach them reverse the operation.

Aduzmtages.

It is absolutely safe from casual detachment. The change from pole to thills or the reverse is made quickey than by any other known arrangement, and without the necessity of using any tools or soiling the hands, It is noiseless in operation and cheaper than any othergood shackle.

I claim the pintle B, spur C, recess E, spring D, and socket F, substantially as described, forming a new and useful improvement in attaching thills or poles to carriages or other vehicles.

G. T. PEARSALL.
