JAMES J. JOHNSTON, OF OOLUMBIANA, OHIO.
FARM-GATE.
SPECIFICATION forming part of Letters Patent No. 254,020, dated February 21, 1882.
v Application filed January 12,1882. (No model.)
To all whom it may concern:
Be it known that 1, JAMES J. JOHNSTON, of Golumbiana, in the county of Oolumbiana and State of Ohio, have invented a certain new and useful Improvement in Farm-Gates; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to accompanying drawings, and to the letters of reference marked thereon.
My invention relates to an improvement in farm-gates; and it consists in the combination and arrangement of the several parts, whereby the gate is braced and is elevated while swing' ing it open throughthe medium of a spirallycurve'd circular incline friction pulley and hinges, as will hereinafter more fully and at large appear.
To enable others skilled in the art with which my invention is most nearly connected to make and use it, I will proceed to describe its construction and operation. t
In the accompanying drawings, which form partof this specification,Figure l is'a perspective view of my improvement in farm-gate. Fig. 2 is a sectional view of the latching and locking device. .Fig. 3 is a detail vertical section of the flanged brace, spirally-curved circular-inclined tread for the coniform friction-pulley, and of the gate and gate-post. Fig. 4 is a transverse section of the gate-post and top view or plan of the spirally-curved incline tread. Reference being had to the accompanying drawings, Arepresents the gate, which consists of bars a b c d and vertical end pieces, ef, and brace B,on the lower end of which is abearing, O, flanged, in which is pivoted a coniformed roller, D, which rests against a tread, g, secured to the gate-post h, which tread is a spirally-circnlarincline. The diameter of the flanged gatepost'h at 'i is recessed for the forked hinge j, secured to the vertical end piece, 6, of the gate, near the upper end of which is an '-shaped hinge, k, which consists of a flat bar having a portion bent at rightangle, forming an inverted L, the short limb of which is furnished with an opening for a pintle,m, (shown in dotted lines,) on the upper end of which is an ornament, a, which moves up and down with the hinge 70 when opening and closing the gate.
The construction of the latch 0 will be readily understood by reference toFigs. 1 and 2, and therefore need not be further described.
The gateis furnished with abrace, B, secured to the horizontal bars I) and c, with the upper end of the brace placed under the lower edge of the bar a and against the vertical bar f, and the lower end of said brace furnished with the bearin g 0, in which is pivoted a friction-roller,
D, which rests against the spirally-circularin; clined tread g, which brace,bearing, roller, and tread will prevent the sagging down of the latch end of the gate, and thereby hold the bars (1,1), 0, and d at right angle to the vertical. end bar, e, and keep the bars f in a vertical position and at right angle to said bars.
The friction-roller l) is made coniformed to correspond with the radius of the inner and outer curve of the spirally-circular inclined tread g, which is furnished with a circular vertical flange, p, which is secured to the gatepost It by means of screws q.
The flanged bearin g G, spirally-circular inclined tread g, and forked hinge j may be con- 'structed of cast-iron by the molding and casting process; but the hinge 7c and its pintle m should be made of wrought-iron.
The degree of elevation of the gate in opening it is indicated by the dotted lines 1" s.
' The flanges of thebearing U will prevent the brace B from sagging and will prevent any displacement of the lower end of the post 0, and by means of said brace B, flan ge-bearings O, friction-pulley D, and spirally-curved 'inclined tread g the gate A will be thoroughly braced and susceptible of sustaining great weight and strain on its latch end without sagging. The gate and its several parts herein described, combined with the post h and spirally-curved incline tread g, impart to the gate as a whole the supporting power and swinging action of a crane.
The advantages of my improvement consist, first, in. the simplicity of its construction and its cheapness; second,-in the manner of bracing it; and, third, in its tendency to swing shut when open.
Having thus described my improvement, what I claim is In a farm gate, the combination of the curved inclined tread g, having vertical flange p, friction-roller D, forming the frustum of a cone, adapted to said inclined tread and pivoted 5 in bearing (lon the lower end of the brace B, so that the angle of strain of the gate A will be upon said roller and tread, the forked hinge j,
pintlem, and post It, constructed, arranged, and operating substantially as herein described, and for the purpose set forth.
