' GATE.

npplication tiled December type which wil be nicely balanced so that it Wilil operate easily and without reqliliiring excessive exertion upon the part of t e o erator.` The invention is illustrated in t e accompanying drawings and consists in certain novel features which will be first fully described and then more particularly pointed ont in the appended claim.

In the drawings:

Figure 1 is a perspective view of a gate embodying m., mventiorn the gate being slfiown in its clbsed position;

`F 2 is a view, )artly in side elevation andipartly in vertica section, of the gate;

Fig. 3 .is a detail transverse section on the line 3-3 of Fig. 2;

` F 4 is a detail perspective view of the latch. f

My gate is intended more particularly for use asa barrier across private roads where it is desirableto separate one field from another tield. It is )able ot' use, however, wherever unrestricte use of a road is not desired. Inl carr ing out the invention, I provide at one` si e of the road a latch post 1 which may be anchored in the ground in any approved manner and is provided in` one side with a vertical groove 2 adapted to receive the free end of the gate. At a n'oier ioint in the height ot' this post, a ing 3 is provided on the base wall of the groove 2 to be engafred by the latch 4 ofthe gate, as shown in 2. At the opposite side of the road, I set up a pair of posts 5 which are of such height as to extend appreciabl above the latch post `and the gate, and at t 1e same side of the road and spaced a proper distance from the posts 5 are other post-s G which are of the saine or approxi@ mately the same height as the posts 5. The aos-ts 5 are spaced aparta sufficient distance io accommodate the gate 7 between them and they serve as snpports for the gate which is" pivotally or hingedly mounted upon and between said posts so that it may swing in a vertical plane. The gate may be of any approved detail form and is preferably com `iosed of a tubular frame 8 having wire netting t) secured thereon and having se- 4, 1925. Serial N0. 73,230.

cured vertically across the traine at its 'tree end braces 10 which reinforce the wire netting and also aid in supporting the guides 11 which are formed byturning inwardly the end portions of the trame to presentvparallel horizontal bars between which `the latch 4 is received. The latch is provided on its sides with lugs 12 playing between two of the braces l0 and, consequently, serving as sto s to engage the saidbraces and limit themovement of thelatch, as will be readily understood. The latch is normally held in itslatching position' by a coiled spring 13 attached at one end to the latch andat its opposite end to the foremost brace 10, as c early shown in Fig. `2.

At the hinged or pivotal end of the gate, a brace 14 is secured u )on the frame and the trame is Jrovided wit i or includes a semicircular trame member' 15 which carries a counterbalance weight 16 which may conveniently be a concrete blockA molded upon the said frame member. The supporting member ot' the gate comprises a pair of crucitorm bodies 17 disposed. at opposite sides of the gate traine and having their vertical arms connected with the' upper and lower traine members by clips' 18, as shown and as will be readily understood, whilethe intersecting horizontal arms are secured at their extremities to the brace 14 and in the counterbalance 16 respectively, shown clearly 1n Fig. 2. The crucitorm bodies are provided with au axle or trunnions 19 which 'are rotatably fitted in bearings 2,() secured upon the inner opposed sides oi. the suplviort-iug posts 5`\vhcreby the gate may rock in a ver* tical plane,as will be understood. At the junctions oi the supporting bodies 17 and the brace 111, guide links 21 are mounted at the opposite sides ofthe gate for a purpose which. will presently appear.

Disposed transversely inthe roadway at opposite sides ot the gate and adjacent the vertical posts 6 are trips 22 which, are essentially crank shafts having their crank portions normally upright.' These crank shafts are' rotatably mounted at their ends upon base bars 23 which lare embedded in the roadway and at their inner ends they are provided with supplen'ie'ntal cranks 1-lbetween which and the respectively adjacent posts (i are mounted springs` 25 which are so set as to yieldably hold the crank shH s in their normal positions. l\f[ounted tor rocking movement upon thebases 2?) and in lli?) axial alinement with the pivots or ournals of the respective crank shafts are rockers 26 which consist each of diverging arms arranged at oppositesides ot the crank shafts, as shown clearly in F ig. 1. To the opposite ends of these rockers are secured the ends ot cables 27 and 2S which extend upwardly theret'rom to and over guide rollers at the top ot' the adjacent post 6 and then to and over similar guide rollers Q9 at the top ot the post and thence downwardly to the gate, the cables 2T being passed through guide eyes El() at the endsot the links 2l and then extended forwardly to be att-ached to the respective lugs 12 or to the body ot the latch, as will be understood upon reference to Figs. 1 and 2. The ends ot the cz bles Q8 are attached to the upper ends ot those arms ot the erucil'orm body 1T which are normally upright.

lt is thought the operation will be readily understood :trom the foregoing description, taken in connectionk with` the accompany ing drawings. The cranks ortrips 2&2 normally stand upright, as previously stated, and the inner arm of the rocker 26 rises trom the ground between the said crank and the gate. A vehicle approaching the gate is caused to ride over the crank and will thereby rock the same trom its upright position to a horizontal position, thereby causing` it to impinge against the forward arm ot the rocker 26, and said arm will be thereby swung downwardly and exert a pull upon the cable 27. The movement of the cable 27 will be initially imparted to the latch t so as to release the same trom the lug or keeper 3 against the tension ot the spring 13, and then will exert an upward pull upon the gate through the link 1,` the lug 12 upon the latch impinging against the innermost brace lt) so that the movement ot the latch will be arrested and the continued pull upon the cable con sequently imparted to the gate. The upward pull upon the gate exerted through the link 2l and the forwardly extending arm ot the rocker body or support 17 will, et course, cause the gate to turn in a vertical plane about the trunnions or axle 19 as a pivotal center, the gate assuming a vertical position between the posts 5 and out ot the path of the vehicle. rlhe vehicle is then driven through the gateway and steered so as to ride over the tar crank 22, whereupon the said crank will be rocked so as to impinge upon the outer arm of the adjacent rocker 26 and pull upon the corresponding cable 28. Upon referring to Fig. 2, it will be readily understood that, when the gate is swung to a vertical position, the upstanding arms et the supporting bodies or plate 17 will be caused to assume a horizontal position at the rear ot the gate supporting posts. Con sequently, when a pull is exerted upon the cable 28 by the passing vehicle, a lifting movement will be imparted to the said arms and the gate, consequently, rotated or turned so as to resume its normal closed position. lVhen the gate is thus swung downwardly. the beveled end Slltl ot the latch will engage the keeper or lug il so that the latch will ride over the lug and assumo its locking engagement with the under side ol the. same. it being understood thal, when the vehicle passes beyond the tirst crank 22, the pull upon the cable 2i' is released so that the spring til can project` the latch to its normal lin'isition. Likewise the .spring 25 will return the crank or trip 22 to its upright position immediately al'ter the vehicle has cleared the same.

ln some climates, heavy snows and like conditions may clog the action ot the trips or cranks .22 so that they cannot be easily turned. To meet this coiu'lition, lA provide the grips ill upon the cables 27 and ilb above. the rockers 2G so that the cables may be easily reached and manipulated by the ops erator or driver ot the vehicle.

It will be readily seen that l have provided a very .simple and inexpensive gate which may be easily opened and closed by the occupant ot a, vehicle without requiring the occupant to alight. The gate ver)` evenly balanced so that it will turn trom closed to open position or vice versa without requiring laborious etlort upon the part ol the operator and, due to its simple construe tion, repairs will lseldom be needed.

Having thus described ther invention, ,l claim:

rlhe combination ot a pair olf supporting posts, a gate having one end arranged be` tween and extending rearwardly beyond said posts, supporting bodies secured to the sides ol the gate and pivotally supported by said posts, a counterbalance secured about the extended end ot the gate and about portions oit the supporting bodies, and operating cables attached to the gate and the said supporting bodies in right angular relation to the, bodies and extending upwardly and over the posts and provided beyond the posts with operating means.

In testimony whereof ll atlix my signature.
