GATE.

SPECIFICATION forming part ot Letters Patent No. 233,642, dated October 26, 1880.

Application filed March 8, 1880.

To all whom it may concern:

Be it known that I, DANIEL SHEETS, of Union, in the county of Montgomery and State of Ohio, have invented new and useful Improvements in Gates, of which the following is a specification.

My invention relates to a form of gate operated automatically by the passing of a vehicle, and is adapted to be operated by hand; and it consists of a double series of parallel bars jointed at the points of intersection, so that the gate is extended or retracted at pleasure, and this motion eifects the opening and closing of the same. Devices consisting of trip-irons and levers are used to operate the same automatically.

The accompanying drawings are made apart of this speciiication, and like letters of reference marked thereon of the different tgures designate like parts.

Figure l is a side elevation of the gate. Fig. 2is a top view of the base and a section of the post centrally through the guides. Fig. 3 is an oblique view ofthe gate and its attachments.

A is a board forming the base, which corresponds to the earth and serves as a support to the superincumbent parts. To the base are secured the posts C and D in vertical position. The post O has mortises to receive the ends of the gate when closed, as shown'by dotted lines. The center of the post D is out out almost the entire length above the base,as indicatedby dotted lines. On the back of this post, and near the top, are guides N on both sides of the mortise, to support the frictionrollers 0, which are attached to the bar R by means of a pin that forms the axes of the rollers. The curved oscillating rod E is supported on standards at both ends, and at its center is supported on the pin M, which passes through the post and forms the pivotal support of the (Model.)

gate-bar L. The bent projection ot' the oscillating rod is connected to the gate-bar by a link or equivalent device, as illustrated at Fig. 1. Near bot-h ends are attached arms to the oscillating rod, which are connected to the crank end of the trip-irons by the stirrup or plates U. The trip-irons Gr have a double bend, the two parts having the relation ot' right angles, and are secured to the base at a suitable distance parallel to the gate. The trip-irons are identical with those in use in the operation of automatic gates, and are operated by the passing vehicle.

The operation may be thus described: The wheel is driven against that part of the tripiron that depresses the rear part of the oscillating rod. This carries the gate-bar to a nearlyvertical position, the effect being to close the parts of the gate upon itself within the post, and thus the Wayis fully open. When the vehicle has passed the gate the partof the trip-iron is struck which elevates the rear eX- tension of the oscillatingrod, and thereby the gate is closed. 'A

rlLhe construction of the gate is not novel, and consists of a double series of bars crossing each other, and so jointed as to admit of extension and retraction. rlhe hand may be likewise used on the bar R to effect the opening and closing of the gate.

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

The gate B, having arms R and L, in coinbination with the guide N, post D, oscillating rod E, and trip-irons G. substantially as and for the purposes set forth.
