AUTOMATIC SWINGING GATE.

SPECIFICATION forming part of Letters Patent No. 350,189, dated October 5, 1886.

Application filed December 26, 1885.

To all whom) it may concern.-

Be it known that I, SAMUEL L. DENNEY, a citizen of the United States, residing at Gap, county of Lancaster, and State of Pennsylvania, have invented new and useful Improvements in Automatic Swinging Gates, of which the following is a specification.

My invention relates to improvements in auto matic gates, whereby is effected the changing of the gate from a true vertical to an inclined position at the same time with the lifting of the forward end of the gate, thus causing it to swing by its own gravity open or shut, as desired. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the gate closed; Fig. 2, a perspective view of theringbracket with ring; Fig. 3, a ground plan of the ring-bracket; Fig. 4, a side view of the ringbracket; Fig. 5, a ground plan of the ring; Fig. 6, a side view of the ring, showing a roller; Fig. 7, a ground plan of the resting-plate;

Fig. 8, a side view of the same; Fig. 9, a view of the lower upright of the gate and the back post partly in section; Fig. 10, a front view of the stop with its notch; Fig. 11, aground plan of the same; Fig. 12, a View of the front part of the gate partly in section; Fig. 13, a view of the gate opened; Fig. 14, a view of the gate lifted, ready to be opened; and Figs. 15 and 16, views of the shaft in two of its positions.

Similar letters refer to similar parts throughout the several views;

The gate A is constructed, in the usual way, with heel and front posts, having horizontal rails r s r tenoned into said posts, with a suitable number of crossed or other vertical rods to give an ornamental appearance to the gate.

Usually in constructing gates to swing automatically open and shut a vertical shaft with a crank at one end to receive the eye secured to the heel of the gate is employed to throw the gate out of its true vertical position,and at the same time lift the front end slightly to disengage the latch from the catch on the post against which the gate closes.

By my improved means for canting and lift- Serial No. 186,814. (No model.)

ing the gate I change simultaneously both ends of shaft H, causing them to move in opposite directions. This I accomplish bymeans of the rings h h, Figs. 2 and 5. These rings, as will be noticed, fit loosely into ring-brackets b 1), Figs. 3 and 4, which are bolted firmly to the gate-post B. Said rings are provided with anti-friction rollers t 15, thus securing great freedom of action in working the gate. These rings are secured to the shaft H, and are set reversely to each other, thus giving to the shaft the requisite inclination by a comparativelyshort crank movement, and thereby securing great leverage and easy control over the gate when opening and closing. The lower eyebolt, 9, secured to the gate, is made to exceed the upper one in length by the inner diameter of the ring 71, as is evident from the drawings. Shaft H is inserted in a socket, F, in which its lower end moves freely. Said socket is pro- .vided with suitable jaws to receive a roller, f,

which rests on plate J, which is bolted to the gate-post B. A pin, 00, projects through said shaft, immediately above the projection 12 on ring h, upon which the eye 57, secured to gateheel a, rests. Thus it will be seen-the weight of the gate is supported by plate J through its sup port upon the pin above the ring, whereby the latter is left free to work without any downward pressure or strain upon it.

To the upper end of shalt H is secured crank q, to the outer end of which rod R B, Fig. 13, is connected. Said rod is connected to levers n n, which are pivoted to posts N N. Thus it will be seen that by drawing the righthand lever away from the gate the position of the shaft will be instantly reversed to that shown in Fig. 16, and the gate will be lifted to that shown in Fig. 14 and will swing open, and by retaining hold of the lever until the gate has swung round to the line of the lever-rod and then releasing .it the front end of the gate is let down upon the rest 0, which relieves the gate-post wholly from the weight of the gate, whereby the post is prevented from sagging.

I use a spring-bolt, m, for securing the gate in its shut position, which slides endwise in a mortise formed in the face of post a, and slides into the open slot formed in catch 0, out of I 2. The combination of the gate Afvertical which slot the bolt is lifted in the movement of opening, as seen in Fig. 14.

What I claim as my invention, and desire to 5 secure by Letters Patent, is

1. The combination, in an automatic swinging gate, of the gate A, vertical shaft H, rings 7 h h, ring-brackets b b, I'OHGI'zSOCkGt F, roller f, plate J, and crank q, substantially as set IO fonth.

shaft H, rings h, ring-brackets b,socket F, roller f, plate J, crank q, rod R, and lever n, substantially as described.
