IMPROVEMENT IN TILTING GATES.

Specification forming part of Letters Patent No. SLQSS, dated February 13, 1877; application filed V October 7, 1876.

To all whom it may concern Be it known that I, ISAAC BROKAW, ot' Litchfield, in the county of Montgomery and State of Illinois, have invented a new and Improved Farin-Gate, ot' which the following is a specification:

In the accompanying drawing, Figure l represents a side elevation ot' my improved farmgate, and Fig. 2 a plan view ot' the same.

Similar letters of reference indicateiorrespending parts.

The invention relates to an improved farmgate that may be opened and closed from the carriage, or by a person on horseback, with great facility, the construction being simple and reliable; and the invention consists ot' a swinging and weighted gate that swings in fulcrums of the gate-posts, and is opened or closed by a suitable cord arranged to withdraw a springlatch for raising the gate, and also to release a brake-spring t`or lowering the gate.

In the drawing, A represents a farm-gate of suitable size and construction braced by side rods a, extending from the fulcrum b at the rear end to the front end ot' the gate. The fulcrum b is supported in slotted bearings of a double gate-post, B, and admits the ready swinging up ot' the gate into an upright position b v a counterpoise, C, arranged in a semi4 circular casing at the rear end of the gate. Asl'Jring-lateh, D, at the frontend of the gate opposite to the fulcruined end, locks the same to a beveled cross-piece, d', ot" a double gatepost, B', at the other side. A connecting rod or cord, d, is applied to the spring-latch, and passed along the gate to a ring or pulley, e, at the top ol' the weighted easing C, or, prefera bly, at the end of a band-spring, f, attached at one end to the casing. The cord d branches out into two parts from a point in front ot' the pulley, and runs o' in both directions from the-gate, and in guidepulleys or staples g of frames E placed at right angles to the gate,

to the ends ot' the same. The frames E are long enough to admit the gate to be readily opened or closed by pulling the cord at either side, without interfering with the vehicle or person on horseback. When either cord 1s pulled, the latch is withdrawn, and the gate swung into open position by the counterweight.

ln swinging into upright position, the spring f bears against a bottom-board, f', and pro- (luces, by tion of such power that the vibrations ot' the i'ulcrumed gate are interrupted, and the steady vertical position ot' the same is secured.

When the vehicle, or person on horseback or on foot, has passed the gate, a pull on the cord at the opposite side releases the brakespring, and swings, by the stretching of the cord, the gate downward, until the springlatch locks again to the gate-post. The gate may thus be readily opened or closed without leaving the carriage, or dismounting, forming by its simple construction and reliable operation, a neat, convenient, and time-saving gate for farms, parks, and other purposes. The gate may also be opened without the cords, by springing the latch back by hand, when the weighted casing swings the gate open. After passing through, it is pulled down land closed by hand.

Having thus described my invention,Iclaim as new and desire to secure by Letters Patent- The gate A, having rear counterpoise C behind the pivot on which it swings, and a front spring-latch connected by cord d passing through end loop ot' bandspring b to the elevated supports E, substantially as and for the purpose specified.
