VILLIAM H. EODERIOK, OF EAST RUSH, NEIN YORK, ASSIGNOR OF ONE- HALF HIS RIGHT TO SAMUEL H. KINSEY, OF SAME PLACE.

IMPROVEMENT IN FARM-GATES.

Specification forming part of Letters Patent No. 152,049, dated June 16, 1874; application filed March 5, 1874.

To all whom it may concern.: T

Be it known that I, WILLIAM H. RoDEErcK, of East Rush, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Gates 5 and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation of the same.

My invention consists in combining, with an ordinary farm-gate, a compensating` hinge at one end, and a caster-wheel or roller at the other, which runs on an inclined way, which also serves as a stop, the arrangement being such that in the passage ofthe wheel over the way the compensating hinge will allow the necessary elevation of the gate, as hereinafter described.

In the drawings, Figure l is an elevation, Fig. 2 is a plan view, Fig. 3 is a diagram, showing the inclined way and roller.

A represents a farm-gate, ot' any ordinary construction, and B B the posts. The gate is arranged to swing on hinges in the usual way. The lower hinge is the same as ordinarily employed. The upper hinge, O, however, is so arranged as to allow the gate-standard to slide endwise thereon, and thereby compensate for the raising movement ot' the swing end of the gate in passing over the inclined way.

To accomplish thisI construct the hinge with a long arm or shank, a., which passes loosely through the gate-standard, and also through eyes b I) bolted to the upper rail. At its end i; is threaded and has a nut, c, thereon, which serves as a gage or stop to hold the gate from falling too low in passing over irregularities in the ground. By means of this nut the gate may be so adjusted as to ride higher or lower at its swing-end, at pleasure.

At the bottom of the swing-end of the gate is a bearing, d, holding the friction wheel or roller f. On one or both sides of the conter is an inclined way, g, concentric, with the hinge-end ot' the gate, over which the roller passes in opening or closing.' At the inner end is a space, h, into which the roller falls when the gate is fully closed, and by which, together with the latch and catch k, the gate is kept in place. At the outer end the way merges with the surface of the ground, over which the roller passes in swinging fully open; hence the movement of the roller is gradual and uniform.

A mutual action exists between the roller and the compensating hinge, for the latter allows the gate to vibrate or slide upon it as the roller passes over the inclined way. If the gate swung in a plane this action could not occur. At the same time the nut on the hinge gages the fall of the swing-end of the gate, and can be adjusted to any position, so that the roller will swing over and clear depressions and irregularities in the ground where it could not run. By the use ofthe roller the gate can be swung without lifting it, and when in line with lthe fence the roller will drop into the space h and retain the gate in position. No strain or sagging comes on the post ,which can be made as light as common fence-posts. By the use ofthe roller, also, no heavy strain or racking comes on the gate itself.

What I claim as new, and desire to secure by Letters Patent, is`

In combination with the swinging gate A, provided with a roller, j', the compensating hinge C, constructed as described, and the incline g, when arranged to operate together, as and for the purpose set i'oth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
