GATE.

Application filed February 16, 1923.

To all whom t may concern:

Be it known that I, ELMER S'riNiiAKiiR, i citizen of the United States7 residing at Chambersburg, in the county of Pike and State of Illinois, have invented certain new and useful Improvements in Gates, of which the following is a specification.

This invention is a gate designed to permit the passage of large stock, such as horses, from a pasture to another field in which water may be obtained and to prevent the passage of small stock, such as sheep or hogs. The invention seeks to provide a gate which may be automatically opened by the stock and will automatically return to its closed position after t-lie stock has passed. The objects of the invention ai'e attained in such a gate as is illustrated in the accompanying drawings, and the invention resides in certain novel features which will be hereinafter fully set forth.

In the drawings:

Figure 1 is a side elevation, partly broken away, of a gate constructed in accordance with my invention;

F ig. 2 is a horizontal section on the line 2 2 of Fig. i;

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1, and

Fig. l is a detail perspective view of a rest which forms an element of the gate.

In the drawings, the reference numeral 1 indicates the hinge gate post and the numeral 2 indicates the latch post which may be of any desired or convenient construction and are set in the ground in the usual `inaniier. These posts form part of a fence, a portion of which is indicated at 3 constituting a division between two adjoining fields. The gate bodyconsists of horizontal bars 4 secured together at intervals by upright bars ,5 and a brace 6 which may be of any convenient or preferred material. To the upper and lower edges of the gate body, I secure hinge straps 7 which are adapted to engage over and be pivotally supported on lugs or studs 8 secured in the hinge post 1 and arranged to permit the swinging of the gate in either direction. Upon reference to the drawings, it will be noted that the end of the gate body is spaced from the post 1 so that there will be no interference between the post and the end uprights 5 of the gate. The post 1 is further constructed at an intermediate point of its heightwith a socket 9 in which is se- Serial No. 619,435.

cured one end of a leaf spring 1() which extends from the post between the uprights 5 of the gate and parallel with the intermediate bars 4 of the gate. Secured between the central uprights 5 and upon the iminediately adjacent gate bar 4L is a rest 11 consisting of a block of proper form and size to tit snugly between the said uprights 5 and provided in its upper side with a notch or recess 12 in which the free end of the leaf spring 10 is engaged. The end of the spring fits easily within the notch or recess 12 so that. it will not bind thereon but may move relatively thereto but at the same time will be retained therein so that it will always be in operative condition. Upon referring to Fig. 3, it will be noted that, when the gate is swung to one` side, the leaf spring 10 will be placed under tension or bowed and when the moving force is withdrawn the tension of the spring will return it to its straight condition and thereby effect reverse movement of the gate so that it will return to its closed position between the posts 1 and 2.

The post 2 is provided near its upper end with a socket 13 which may be lined with metal, as shown at 14, and the sides of the post are beveled, as indicated at 15, so that the latch 16 may ride easily over the sides of the post to engage the socket. The latch 16 consists of a bar disposed longitudinally of the gate body and Slidably supported between the uprights 5 at the free end of the gate and in a guide or bearing 17 secured upon the intermediate uprights near the upper end thereof. A spring 18 is coiled around the latch between the said bearing block 17 and an abutment or its equivalent 19 on the latch, said spring tending constantly to expand and thereby hold the latch in engagement with the socket 13, as will be readily understood. The latch bar projects through the guide or bearing 17 toward the hinge end of the gate and to the extremity of the latch bar is secured a head or cam 20 consisting of an arcuate plate extending to both sides of the latch bar and following a curve having its center in the longitudinal axis of the said bar. Upon the outer sides of the intermediate uprights 5 near the upper ends thereof, I secure brackets or loops 21 upon which 4are fulcruined levers or swinging operating lbars 22 which converge toward the head or cam 20 and are equipped at their inner ends with rollers 23 bearing upon the concave face of said head or cam, as clearly shown. The outer divergent ends ot the arms or levers 22 extend to points equidistant from the tree end of the gate and in the vertical plane of said end, as clearly shown, the brackets or fulcrums 21 being eccentric to the member 20` so that, it the tree end of the lever or operating arm be swung toward the gate, the inner end thereof will be caused to ride upon and exert pressure against the member 20` so that it will be moved inwardly, as shown by the dotted lines in Fig". 2, and the latch thereby withdrawn from its engagement with the socket or keeper 13. lf the pressure upon the bar 22 be continued, it will be exerted against the free end of the gate body and the body thereupon swung upon its hinges, as will be readily understood. YWhen the latch is thus withdrawn from the keeper or socket 13, the spring 18 will obviously be compressed so that, when the pressure upon the arm 22 and the gate is withdrawn, the spring will expand and project the latch so that it may again engage the keeper.

The operation is thought to be clear from the foregoing description, taken in connection with the accompanying drawings. The latch is normally held in engagement with the socket or keeper and the gate thereby held against movement so that it will re main closed. The operating levers 22 are located at a suiticient height above the ground to permit them to be engaged by the breast or body of a horse or other large stock but are so high from the ground that they cannot be engaged by sheep, hogs or otherI small stock. TWhen a horse, for instanc-e, desires water, he will move against the adjacent operating arm or lever 22 and will swing said arm toward the gate body and thereby withdraw the latch. The animal will continue his progress and will thereupon open the gate against the force of the leaf spring 10. As soon asthe animal has cleared the gate, the spring 10 will return it to closed position and the spring 18 will return the latch and the levers 22 to their initial positions. dien the animal returns to the pasture, he will move the gate in. the opposite direction by pressing upon the formerly inoperative lever 22 and operate the gate in the same manner as it was previously operated.

It will' be readily noted that my improved gate is exceedingly simple in the construction and arrangement of its parts and may be easily operated, always returning to closed position immediately after the opening torce has been withdrawn. The closing spring is so disposed that the animal opening the gate cannot come in direct contact with the spring and possible breaking or the spring is thereby avoided while at the same time there is ample space to accommodate the bowing of the spring when it is put under tension. It frequently happens that where stock is pastured in vone lield which contains no water and water may be had in another field, .the larger stock will jump over the dividing 'fence vor break through it, and l have observed that they quickly learn to push open an ordinary gate under such conditions. The ordinary gate, however, will not restrain the small stock and it is very desirable to permit the larger stock to pass at will from one iield to anothe f lield while restraining such passage ot' the smaller stock. This purpose is at tained by the use ot my improved gate.

Having thus described the invention, what is claimed as new is:

1. ln a gate, the combination of a latch post, a swinging gate mounted adjacent the post, a slidable latch bar mounted upon the gate, yieldable means holding` the outer end ot the latch bar normally in engagement with the latch post, a laterally projecting cam plate on the inner end of the latch, and an operating member; mounted upon the side of the gate body and riding upon the cam plate whereby pressure thereon will withdraw the latch.

2. ln a gate, the co-nlbination of a latch post, a gate body mounted for swinging movement adjacent the latch post, latch bar slidably mounted on the gate in position to engage the latch post, a spring coiled around the latch bar and bearing at one end against a fixed part of the gate body and at its opposite end upon the latch bar, whereby to hold the bar in engagement with the post, a laterally projecting tix-ed cam at the inner end of the latch bar, and an operating lever tulcrumed between its ends upon the side of the gate body eccentric to the cam plate and bearing at its inner end against the cam plate.

ln testimony whereof I aiiix my signature.
