T0 @ZZ whom t may concern.-

Be it known that I, CHARLES P. HowE,a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Farm-Gates, of which the foi lowing is a specification, reference heilig had therein to the accompanying drawings.

My invention relates to certain novel and valuable improvementsin that class of swinging gates which are adapted to be opened and closed by persons approaching them in vehicles without necessitating the stopping and alighting ofthe occupants; andthe invention consists in the improved features of construction and combination of parts, which will be fully understood from the following description and claims, taken in connection with the annexed drawings, in which- Figure lis a perspective view of a gate pro' vided with my improved operating devices; Fig. 2, a detail plan view of a portion of the gate, showing the hingc-post in horizontal section; and Figs. 3 and 4, detail side elevations of the hingepost, taken from different sides of the same.

Referring to the annexed drawings by letter, A A designate the two gate-posts, which are arranged on opposite sides of the roadway, and 1li-designates a post on one side of the roadway, to which the gate is latched when fully opened, to allow a vehicle to pass.

The gate B may be constructed of wood or metal, like any ordinary farm gate, and itis attached to the post A by long hinges C C, each composed of eyebolts a a, secured to the vertical gate-post A, and an eyebolt, a', secured to the vertical bar D of the gate,through the eye of which bolt passes a headed bolt or pintle, I, secured to the eyes of the bolts a a, as shown in Fig. 4 of the annexed drawings. It will thus be observed that the gate B can be raised or lowered vertically, and also swung around one quarter of a circle from post A to post A2. To the vertical bar D', at the free end of the gate, I apply a latch, c, which is adapted to engage either with a beveled catch, c', on post A', or with a similar catch, c?, on post A. To the upper end of the gate-bar D, I rmly bolt two rigid strap-irons, E E, which` rise verti cally and afford bearings for the short shafts (No model.)

of two rollers, F F', arranged at asuitabledistance apart between said strap irons, and pref erably slightly tapered Vhen the gate is shut, as indicated in full lines, Fig. 2, the upper roller, F, rests upon the lowest part of one limb, g, of a segmental cam shaped rail, G, which is rigidly secured to the post A above the upper hinge C, and when the gate is fully opened the said roller F rests upon the lowest part of the limb g of said rail G.

The rail G is bent through somewhat more than onehalf of a circle; and it consists of two inclined planes or limbs, g g', terminated by angular portions g2 (fl, through which the screws or bolts pass that rigidly secure lthe rail to the post A, as shown in Fig. 2 of the aunexed drawings.

At g'n is a rounded ridge, which is the highest point ofthe said inclined planes, and at g is astraighthorizontal portion of the rail which is at right angles to the post A and designed to render the rail compact and at the same time afford the proper length of track.

A'l designates a horizontal arm or bracket, which is rigidly secured to the post A parallel with the roadway, and to which is fulcrumed a long lever, I, the shortestv arm of which is connected by a rod, N, to an eyebolt or staple, L, secured to the vertical hinged gate-bar D just below the upper hinge C. The shortest arm of the lever I is also connected by a link, i, to the shortest arm of a lever, K, which is fnlcrumed on the post A2 at a suitable height vfrom the ground. From the longest arms ot the levers I and K depend wires having rings or other suitable handles attached to them,by which a person riding or on foot can operate said levers and open or sh ut the gate.

It will be observed that the vertical irons E E receive between them the cam'rail G; also that the distance between the two rollers F F is such as will allow the gate to beraised bodily the proper height before the lower roller, F', impinges against the under side of the camrail G.

In operation, suppose the gate is shut, as indicated in Fig. 1 of the annexed drawings, and a person riding or walkin g in the roadway approaches it in either direction, he will pull on the longest arm of the lever nearest him,

which will lift the gate bodily until the lower roller, F', bears against the bottom of the limb or inclined plane g of the rail G, when, continuing to pull'on said lever, the roller F' will ride up said inclined plane, and thus swing the gate around until the ridge g3 is reached,when the gate is allowed to descend and the upper roller to bear upon and roll down the inclined plane g, thus completing the opening of the gate by swinging it around and causing its latch c to engage with the catch c2 on the post A. After the person has passed through the gateway far enough to reach the wire depending from the opposite lever, he pulls on the long arm of this lever, and thus raises the gate free from its engagement with the post Aaud causes the lower roller, F', to bear against the bottom side ofthe inclined plane g of cam G. By continuing to pull on said lever the gate will be swung around until roller F reaches the ridge f/3 of said cam, at which point the gate is allowed to descend until the upper roller, F, bears upon the top of theinclined plane g of the cani G, when the gate will swing shut by its own gravity and be latched to the catch on post A.

A person walking will open the gate by simply unlatching it from its post A and swinging it open on its hinges, when it will-swing shut again by its own gravity; or, in other words, by the upper roller, F, descending the inclined plane g ofthe cam-rail G.

It will thus be observed that in moving the gate by means ofthe levers from a latched position the first eighth of a circle thelower roller, F, is caused to act against the bottom of the cam-rail, after which the gate is lowered and the upper roller, F, allowed to descend on top of this rail. Vhen the gate is opened by a person on foot pressing against it, only the upperroller, F, isbronghtinto action upon the top ofthe cam-rail.

Having thus fully described my invention, I

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a swinging gate adapted to be moved vertically, of a double inclined segmental cam-rail secured to a gatepost, and rollers applied to upper extensions of the gate-bar above and below said rail, substantially as described.

2. lThe combination, with a gate which is adapted to be swung` horizontally and to be bodily moved vertically, of elongated hinges, a double inclined segmental track secured to the gate-post, the rollers F F/, adaptedto operate on opposite sides of this track, the levers I K, and a rod connecting the lever I to theV vertical hinged bar of the gate, substantially as described.

3. The combination of a swinging gate which is adapted to be moved vertically and which is connected to a gate-post, A, by elongated hinges G C, and provided with a latch, c, the posts A A2, provided with catches and located with respect to the roadway as described, levers fulcrumed on said posts,linked together and connected to the gate by a rod, N, a double inclined segmental cam-rail secured to said gate-post A, and rollers jourualed in extensions of the gate-bar D and receiving between them said cam-rail, substantially as described.

4. The combination, with the gate-postsA A and the gate hinged to the former, so as to be movable vertically thereon, of the stationary scgmental rail G, composed of the oppositely-inclined portions r/ g', united by a ridge, g, the said rail being attached to the hingepost A, and the rollers F F,journaled upon the inner post, D, ofthe gate and adapted to bear, respectively, above and below the said segmental rail G in the operation of opening and closing the gate, substantially as set forth.

In testimony whereof I'afx my signature in presence of two witnesses.
