SPECIFICATION forming part of Letters Patent No. 310,006, dated December 30, 1884) Application filed February :9, 1884.

T 0 (0% whom it may concern.-

Be it known that 1, WM. R. WHITE, a citizen of the United States, residing in the city of Neoga, in the county of Cumberland and State of Illinois, have invented certain new and useful Improvements in Sliding Gates, of which the following is a specification.

My invention relates to sliding gates and to devices for moving and locking the same; and it consists in combining with the operatinglevers a sliding spring-bar, rod, and pivoted bars, all as fully described hereinafter, and as illustrated in the accompanying drawings, in which Figure l is a side elevation of a sliding gate showing my improvements, the gate being partially open. Fig. 2 is a transverse sectional elevation of the gate, the parts being in the position shown in Fig. 1; Fig. J, a perspective View of part of the panel, post, and latch. Fig. at is a plan of the post, panel, and latch, and Fi 5 is a view showing the construction of the sliding bar.

The sliding panel A of the gate consists of longitudinal bars and uprightand diagonal strips a a I) Z) c, as shown, or is otherwise constructed in any suitable manner, the upper bar being longer than the panel, and having its hearings on rollers d (I, supported by posts 13 D, as shown, the particular manner of supporting the gate being immaterial, provided the gate can slide easily back and forth across the roadway to and from the latch-post E.

In order to permit the gate to be opened and closed by persons on horseback or in vehicles, I use the following appliances: The post D is of sufficient height to support the usual operating-levers, F G, which are pivoted to the cross-bar H, supported by the post, and provided with pendants f.

To the forward part of the panel A is pivoted one end of a bar, I, connected at its inner end to a second bar, J, which'is pivoted to the upright B or any other suitable support, so that by bringing the two bars in line, the gatepanel will be forced to the post IQ, while it will be retracted by elevating or depressing the bars at the point of their connec tion. This movement of the bars is effected (No model.)

The bar K is connected in any suitable manner at the upper end to the levers F G, and the rod L is connected at one end to the bar K and at the other to the bar J, near its pivotal point, on post B. As shown, the connec tion is such that the gate is opened by the lifting of the sliding bar K, the rod L in this instance being connected to the lower end of the bar K. The swinging of the levers F G elevates or depresses the sliding bar K, and by means of the rod L swings the bar J to or from a horizontal line, and thus opens or closes the gate. In the construction shown it is necessary to lift the bars I J in order to open the gate, the weight of the bars therefore rendering the operation difficult. To overcome this difficulty I combine with the operative parts of the gate some suitable means for counteracting this force or weight, which may be a counter-weight, but is preferably a spring. The particular mode of accomplishing this purpose which I prefer is shown in the drawings, and consists in making the sliding bar K of two spring-strips, g 9, connecting them vto a separating-block, t, and drawing them towhich may be set to put any desired tension on the strips. One of the strips is pivoted to each of the levers F G, and as the strips have a tendency to approach each other, they tend to lift the inner ends of the levers, and thus to open the gate. This action is not sufficient actually to move the gate, but it will counteract the weight of the bars I J, so that to open the gate only sufficient power is required to overcome the friction of the panel on its rollers and set it in. motion.

In Fig. 2 the gate is shown as partially open, and it will be seen that the ends of the spring-strips r g are nearest to each other and exert the least force; but when the gate is closed or opened to its full extent the levers F G will stand at an angle to each other; consequently their inner ends will be farther apart, and the spring-strips g y will exert their greatest force, tending to move the levers and to aid in starting the gate, either in opening or closing. 7

Instead of making the strips of spring material, they may be drawn together by a rub- ICO gate-panel.

ber spring, j. (Shown in dottedlines, Fig. 5.) Vhen the bars I J swing downward to open the gate, as shown in dotted lines, Fig. 3, the counterbalance or spring is arranged to tend to lift them, In this figure the bar I is shown 1n dotted lines as pivoted to the side of the The post E has a recess, as, to receive the notched and beveled end of one of the bars a of the panel, and to this post is hung alatch, M, consisting of a stout bar bent to form a cross-piece, n, projecting side loops, m m, and ears 8 to receive bolts 2, by which the latch is pivoted to the post, a pin, a, limting its downward movement. As the gate 1s pushed to the post E the beveled end of the bar a strikes and lifts the latch M until the same drops into the notch 3 in the bar a, and effectually secures the gate, while the contact of the end of the bar a with the sides of the notch w prevents the gate from yielding to side pressure. A person at either side of the gate can readily lift the latch by grasping the adjacent loop m.

The latch described is comparatively inexpenslve, easily applied, and, once adjusted, is not liable to get inoperative from shrinking of the wood -or wearing of the attachments. When the gate is to be left free to be operated by the levers F G, the latch M is lifted and held in position by inserting a pin in a hole 'w, in the post E.

I claim- 1. The combination, with a sliding gate, of pivoted bars I J, one connected to the gate and the other to a stationary support, and levers F G, verticallysliding spring-bar H, and rod L, directly connecting said sliding bar K at its lower end and the barJ near its pivotal point, substantially as set forth.

2. The combination of the sliding gate, operating-levers F G, sliding spring-bar K, so constructed as to exert its force to bring said levers to a horizontal position, bars I J, and rod L, as and for the purpose set forth.

3. The combination of the sliding gate, bars I J, levers F G, rod L, and sliding bar K, consisting of spring-strips g g, substantially as described.

4. The combination, with a sliding gate, of a vertically-movable bar, K, consisting of spring-strips g 9, means for drawing them together, and operating-levers, to which the ends of the strips are secured, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
