GATE.

, SPECIFICATION forming part of Letters Patent No. 786,084, dated March 28, 1905.

Application filed March 21, 1904. Serial No. 199,191.

To (LZZ whom it may concern.-

Be it known that I, J OHN ANDERSON, a citizen of the United States, whose residence and post-oflice address is at No. 5520 Ohio street, in the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Gates, of which the following is a specification.

My invention relates to that class of gates used mostly in agricultural districts for inclosures which are opened occasionally for the passage of wagons, carriages, and other vehicles; and the object of my invention is to provide a gate which can easily be opened and closed in either direction by any person on foot, seated in a vehicle or on a load of any reasonable height, and that can be raised in the winter to-swing clear of the snow. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is an end elevation of the gate and operating mechanism, being a full view of the operating-handles and connected wires, which are broken to indicate that they are of greater length than shown. Fig. 2 is a side view of the gate in aclosed position. Fig. 3 is a plan view of the gate and operating mechanism, the dotted lines showing the open position of the gate. Fig. 4 is an enlarged plan view of the circular arc lever forming part of the operating mechanism. Fig. 5 is a detail of the locking spring and bar. Fig. 6 is a reverse view of Fig. 4, showing the forked end of the top rail of the gate, which is shown in dotted lines in Fig. 4.

Similar letters refer to similar parts in the several views.

The gate A is made of any suitable material, design, or size. The part B, together with the top and bottom rail of the gate and the angle-plate O, form the hinge part of the gate. These parts are pierced to receive the pivotal bar D, which is held in the lugs Eon the post F, as shown in Fig. 2. In this figure the gate is shown in the lowest position. When raised to the highest position, the bottom rail rests on the log 0 and the angle-plate O rests on the lug e a. This change is made by the withdrawal and reinsertion of the pivotal bar D. At the free end of the gate a flat spring G is aifixed. This spring is adjustably attached to and operated by a bar H, which is supported in a horizontal position below the top rail of the gate. The end of this bar passes through the spring G, which is held and adjusted on the bar by the two nuts it on the threaded end of the bar.

Attached to the top rail of the gate by the pivot-bar D is a circular arc lever I. This lever is provided with an operating-pin J, which projects down to the forked end K of the top rail of the gate. This fork is sufliciently large to permit a limited side movement of the pin J and a limited rotation of the lever I. In the leverI are two apertures L, adapted to receive and hold the ends of the spring-bar H. The circular arc of this lever is in the form of a grooved rim M, adapted to receive and hold the operating chains or cables N, one end of each of these cables being attached to the lever, the other ends being connected with extensions attached to the operating-levers O, which are pivotally supported on posts P, which are set at the required distance from the hinge-post F and a little to the rear, as shown in Fig. 2. Above the operating chains or cables N and attached to the levers O is a tension rod or cable Q, which holds the cables N taut. Set at the required distance from the post F are gate-posts R and S. The post R is arranged to hold the gate closed at right angles to the operatingcables N, and the posts S are arranged to hold the gate in the open position in either direction. Each of these posts is provided with a suitable catch to engage and hold the spring G. Directly back of the hinge-post F is an auxiliary post T, to which a suspension-rod U is pivotally attached at one end, the other end of said rod being linked to the top rail of the gate.

When the gate is constructed and erected erator. If the person be in a high vehicle or l porting-post F; a circular arc lever I pivoton a high load, the higher part of the operating-levers can be seized and the gate opened in either direction.

When the operating-levers are moved to open or close the gate, the motion is communicated by the cables N to the leverI, which because of the free play of the pin J in the aperture K is rotated sufliciently to draw the spring-bar H and spring G from contact with the catch g. The pin J then comes in contact with the side of the aperture K and swings the gate on the pivotal bar D.

\Nhat I claim, and desire to secure by Letters Patent, is-

1. In a gate of the kind described, the combination comprising the gate A having a hinge-bar B and plate C; a supporting-post F having lugs E and a connecting pivotal bar D; a circular arc lever I connected with gate A by the bar I) and pin J and having agrooved rim M; a pair of chains N attached to said lever in said rim; a pair of operating-levers 0 connected with said chains and pivotally supported on a pair of posts P; a tension-rod Q connecting said operating-levers; a springbar H connecting the circular arc lever I with a spring G aifixed to the free end of the gate A and means for adjusting said spring on said bar, substantially as described and for the purposes specified.

2. In a gate of the kind described, the combination comprising a gateA hinged to asupally attached to said gate, connected thereto by a pin J, a connecting-rod I-I attached to the lever I, and a spring Gr attached to said gate and the rod H; a pair of cables attached to the lever I; a pair of operating-levers connected to said cables; a pair of posts P supporting said levers, and a tension-cable connecting said levers, substantially as described and for the purposes specified.

3. In a gate of the kind described the combination comprising a gate A and supportingpost F; a circular arc lever I pivotally attached to the gate A by a pin D and connected with the forked end K of the top rail of said gate by an operating-pin J; and a rod H attached to said lever, through apertures L in said lever; and means for operating saidlever and said rod; and a spring-catch attached to said rod, substantially as described and for the purposes specified.

4:. In a gate of the kind described the combination comprising a gate A and means for supporting said gate; a circular arc lever I pivotally connected with said gate, and having an operative pin J; and a rod H loosely attached to said lever, and means for oper ating said lever and said rod substantially as described and for the purposes specified.
