IMPROVEMENT IN FENCE-GATES.

Specification forming part of Letters Patent N 0. 18,309, dated June 20, 1865.

'tion and operation of the same, reference being llad to the accompanying drawings, makinga part of this specfication, in which Figure 1 is a plan view of the gate. Fig. 2 is a side elevation. Fig. 3 is a detached section.

Like letters of reference refer to like parts in the views.

Our improvement relates to the mode of operating gates, as herein'described.

A represents the gate, between the posts B and (J, that is hinged to the post B.

F is an arm or guide, forming the segment of a'circle, that is secured to the top oftthe hinged end of the gate by a plate, D, and screws 0, and extends round on the other side ofthe post B, as represented, fitting in a place cut'out in the upper rail, 1), of thei'ence. This arm is grooved out on theunder side, as shown in Fig. 3, in which a small pulley, arranged in the rail 1), runs as the gate is opened and closed. (indicated by the dotted lines at in Fig. 2.) The gate swings in the plane of the circleot' the segment F, as the point 0, on wh ch it turns or is hinged to the post, is the center of the segment of the circle forming the arm.

The plate D, by which the arm F is secured to the gate, forms a part of the upper hinge, as shown at c in Fig. 1.

f is a cord passing over the pulley d on the side that the arm is on, and is attached to the arm, the cord suspending a weightin the lower part of the fence, as indicated by the dotted lines 9 in Fig. 2.

This gateis designed to open but in one direction, and fastens as it shuts by means of a spring-latch, E. When the gate is opened more or less, as indicated by the red line in t Fig. 1, the arm Fis moved round, as indicated by the dotted lines in Fig. 1, drawing the cord over the pulley, elevating the Weight g, and when the gateisreleaseditimmediately swings shut, by means of the weight drawing the arm F back to its former position, as shown in the figures. The momentum of the gate decreases gradually as it closes, for the more the arm F is turned round and the cord drawn over the pulley the greater will be the leverage and the force with which the gate is first movedas it closes, causing it to swing "shut smoothly,

' without slamming or shutting with a force that is not required.

In place of the arm F being on the side of the gate, as represented, it can be on the other side, or there can be a similar arm, as seen at J, in which the cord will be attached at 'i to the end of the arm, and pass over a pulley connected to the post or rail b, or over the pulley 61, so that when the gate is opened thecord or chain will be drawn over the pulley that will close the gate when released, as'with the other arm. The arm J can be connected to the gate by the plate D, as is the arm F, and either of the arms can be used, as both operate the gate with ease and facility, in a similar manner. The groove in the arm F, over the pulley, protects the pulley and cord and prevents the cord from wearing out so rapidly as it would other; wise.

What we claim as our improvement, and desire to secure by Letters Patent, is-

The arm F or J, in combination with the gate A, cord f, and weight y, when combined and operated substantially as and for the purpose set forth.
