Application filed April 20. 1907. Serial No. 369.241.

111,0 =to whichl it appertains to make and use the @same vMy invention relates to automatic gates. s .It 'hasgforits object to provide an imroved gate which is capable of being un- 115, yocked, opened and locked open by a vehicle gnapproachingzin either direction and afterwards released, closed and locked by the vehicle.' after it has passed through said gate. ,The invention consists-in the features of gl-20. y. construction and combinations of parts herev,1.25. vention: Fivure 1iis a front elevation of the gates ;-close Fig. 2 is a side elevation nshowing the gates open.l Fig. 3 is a plan viewishowing. the gates open, the end por f tions of the cross bar being broken away, and

. 30 .Fig..4 is la broken inner face View of one of the posts With the gate open.

. Referring more particularly to the drawings, 1,' lare the road posts connected by a icrossbarf2. 4 One of the gates 3 is hinged to ,35 i. each lof said posts. Said gates are preferably imadeiof metal frames with wire meshes as ,.shoWn. At theupper end of e'ach gate is a crank arm 4, between which and the central .portion l of the cross bar 2 is arrangedl a x40 .springi normally holding said gate closed.

,.Anothercrank 6 is formed by a rentrant ...angle-inthe metal frame of each gate. On said latter crank are mounted telescopic rods, .one 7 4extending up and another 8 The opposite ends of thc rods 71 are connected to cranks 9 on the rock- -ingfshaft 10 which is provided with two other cranks 11 arranged in the paths of the :Wheels-of vehicles passing over the road.

. 50,Sai,d rocking shaft is normally held in an ;,11prightpos1tion by means of a spring 12 preferably .arranged between one of the cranks 9 and an upright bracket 18. The .rods 8 are connected to cranks 14 on another .155 rocking Ashaft .15 having cranks 16 in the 'ing a bent strip road and equipped with a spring 17 connected to the bracket, 18.

The gates are locked closed by spring pressed latches 19, each preferably comprisextending across the inner face of one of t e road osts and pivoted on the sides thereof. Sai bent strip is formed with a notch or depression 2O to receive the lower rail of a gate. Trips 21 and 21ZL are pivoted on the outer face of each post be ow the rear ends of the latch 19. Said trips are connected by wires 22 and22, or other suitable connections, with

crank arms

23 and 24, respectively, on the rocking shafts 10 and I which extend b elow the pivotal axes of said shafts. A double latch 25 is mounted farther up on each post and comprises a bent piece extending across the outer face of said post where it is equipped with aspring 26. The ends of said bent piece, on which the latches proper are formed, extend past the inner face of the post in position to grip the upper rail of the gate when it is swung open. A single rocking trip 27 is ada ted to operate the latch 25 when it is roc red in either direction. Wires 28 and 28u connect the opposite ends of said trip 27 with the cranks 9 and` 14 respectively on the

shafts

10 and 15. The push rods 7 and 8 are made in telescopic sections to permit either pair to be used or opening the gate and at the same time allow the other pair to be extended, when the latches for releasing the gatos are being operated without acting upon the gate at all.

If a vehicle approaches from the direction of the rocking shaft 10, its wheels will depress the cranks 11 towards said gates thereby turning the cranks 9 in thc same direction and exerting pressure through the rods 7 upon the gates to open the same. At the 'first movement of said rocking shaft, the crank arms 23, which are turned away from the gates as the cranks 9 and 11 are turned towards them, release the latches 19 by means of the Wires 22 and trips 21. When the gates are opened to their full extent, they are caught and locked by the latches 25. After the vehicle has assed through the gateway, the wheels t ereof depress the cranks 16 away from the gates thereby turning the rocking shaft 15 and the cranks 14 in the same direction and releasing the latches 25 by means of the trips 27 and Wires 28a. As soon as the latches 25 are released, the gates are automatically closed by means of the springs 5 and as soon as the lower rails of said gates reach the notches 2O in the latches 19, they will be engaged and locked thereby. If a vehicle approaches in the opposite direction, the operation is reversed, the rocking shafts .15 being employed to open the gates and the rocking shaft 10 toclose them, it being noted that the rods 7 and 8 are extended when their rocking shafts are turnedv away from the gates.

I claim:

l. A gate having a latch for locking it closed, a latch for locking it open, means operated by an approaching vehicle for releasing the Erst named latch, means including push rods directly connected to the gate for opening the same in either direction and also operated by said vehicle, means for releasing said last named latch operated by said vehicle,y after it has passed through the gateway, and means to automatically close said gate when released.

2. The combination, with 1a hinge post, of a gate hinged thereto, a latch mounted on said hinge post for locking said gate closed, a latch for locking it open, means operated by an approaching vehicle for releasing the first named latch, means connected to the gate for opening the same and also operated by said vehicle, means for releasing said last named latch operated by said vehicle after it has passed through the gateway and means -to automatically close said gate when released.

3.
