4 Claims.

' This invention relates togates, and particularly to means for opening the gate on the approach of a vehicle thereto and the ,subsequent closing of' the gate after the passage ofthe ve- 5 hide.

means controlled by the vehicle passage; whichv has provision for adjusting the counter-balancing weights, and in which the shock incident to passage of the vehicle is absorbed so that neither jar to the vehicle nor undue strain on the gate or parts may be exerted.

-The means by which the foregoing and other objects arel accomplished and the '.manner of their accomplishment will readily be understood from the following specification on reference to the accompanying drawings, in which:

Fig. 1 is a perspective view showing' the relative positioning of the gate and the actuating mechanisms therefor.

Fig. 2 is a side elevation of the gate taken on the line II-II of Fig. 3; and Fig. 3 an end elevation of thegate and side elevation of the actuating mechanism.

Fig. 4 is a side elevation of the hinged end of the gate showing a modied Way of attaching the raising cable; thegate as inthe preceding views being closed; and

Fig. 5 a corresponding end elevation; and

Fig. r6 is a side elevation corresponding to Fig. 4 showing the gate open, one of the supporting parts being omitted in both Figs. 4 and 6.

Referring now to the drawingsin which the various parts areindicated by numerals:` v The gate may be of any desired form o-r structure, and for purposes of illustration, is shown to comprise a top rail I0, bottom rail II, and end rails I2 and I3', forming a frame worksupporting a latticed wireI structure I4. The top vrail Ill has o an extension I5 beyond the end rail "I3, andthe bottom' rail IIl has an` arcuatelywcurved. extensionl I6, likewise beyond the end rail I3, this latter extension curving upwardly and beingjoined y to the top rail extension I5.

The rail I3, substantially midway of its height, carries a hub I'I which is pivotally mounted on a horizontal pin' I8 disposed at right angles to the gate structure and carried by posts I9 which are firmly set in the ground. The ,hubmember I'I may be a pipe tting of the cross type and the end rail i3 in two sections screwed thereinto, ithe pin I8 passing through the branches of the cross at right angles to the rail connecting. branches. Preferably an intermediate member 2) extends'horizontally land rearwardly from a connection with the hub Il to the extension I6 of the bottom rail.

Carried by the rearward extension I5, I6 of the gateis a counter-balance weight structure, this structure preferably comprising an arcuate channelway 2I disposedalong the arcuate extension I6 and being rigidly securedthereto. l This channelway is adapted to receive weights 22, such number of these weights being used as is necessary to effect va counterbalance of thev weight of the gate structure, itrbeing obvious from the. foregoingl and subsequent descriptions that the weight of the gate must Asomewhat over-balance the weight of this counter-balance in` order that the gate may close by gravity'`` To provide for adjustment of the counter-balance weight structura abutment anchors 23 are provided, which anchors permit the placing or removal of the weights 22-A, 22-'B, or the shifting of these weights as desired abovethe weight 22-C, the channel 2l being extended upward for that purpose. The weights 22 below the cablesis made to Athe drum as. by rivets or bolts 33 near the upper portion thereof. The two cables 3 I, 32 extend downwardly and forwardly to and over pulleys 34, 35vrespecti-ve1y,v and thence in opposite directions to the actuatingA mechanisms. Interposed in each of the cables-between rthe pulleys 34 and 35 and the actuating mechanisms are tension springs-36, 31 respectively.

From .thesespring sections ,the cables extend rey spectively to and over pulleys 3B, 39; andl 4I), 4I.

, respectively to trip levers .42, 43. The lower ends the horizontal member 62.

store this member to upright position.

of these levers, as the lever 43 (Fig. l), are provided with hub members 44 which are turnably mounted on horizontal bar portions 45 forming part or" actuating members, generally designated by the numerals 46 and 41.

Eachk actuating member comprises this horizontal portion carried in bearings 48, 49, and having at its inner end an upwardly turned portion 5e which is reverselyl bent to form a horizontal arm 5|, adapted to operably contact the lever 43. 'At its outer end the horizontal portion 45 has an upwardly turned and inverted shallow U shaped continuation4 52, the bottom of the U being greatly elongated as compared with the length of `the legs. Preferably the outer leg of the U has an outwardly turned portion53 which is journalled in a bearing 54, the bearings 48 and 54 being suitably carried and alined by a base 55. Positioned adjacent the base 55, is a frame work comprising upright posts (it, Si and a horizontally disposed member 62, the pulley 4|! being mounted adjacent the lower end of the post 6G and the pulley 4| adjacent the top of the post 5). 63 `is a tension spring acting to "pull the lever 43 into vertical position, movement being sto-pped bya stop member 5t mounted on 55 is a spring which is secured to the member 62 and to the arm 50 of the actuating member and `adapted to re- 66 is a latch mounted as on a pivot pin 51 carried by the post 6|, which latch has a notched lower end 68 adapted to engage with and retain the swinging end of the trip lever 43 whenv same is depressed by action of theI horizontal arm 5|, the latch being held inv engaging position by a tension spring 69. 10 is a stop limiting this movement. 'Il is a similar latch for the lever 42.

A cable 15 extends from the arm. `5| of the actuating member 46 to the latch 1|, and a similar cable 165 from the arm 5| of the actuating member 41 to the latch 66.

The gate is intended to close, and is counterbalanced toy allow closing by gravity. The free end of the gate, formed by the rail I2, when closed is disposed in a slotted post 8G, shown in Fig. 1 as a channel-shaped post 80, as of wood, and in Fig. 2 as a channel-shaped post ll-A.

It is sometimes found that when the gate is raised (Fig. 6) the relaxed tension of the spring of the cables 3|, or 32 as the case may be, acting on the short radius of the drum is insufficient to hold the gate steady. In Figs. 4 to 6 inclusive the cables, 3| and 32, after passing partially gfaround the drum. 36, are secured to a ring 85 which is slidably mounted on a rod 86, having one end secured to the drum and its opposite end as through a block 81 to the channel 2|. lSpring sections 3|-A may be interposed, as before, betweenl the cable and the attaching means, the ring 85.

In constructing the device the posts I9 are set up adjacent the gateway opening and the gate mounted on the pinv i8 supported by the posts.

I'Ihe actuating members 46 and 41 are positioned in theedge of the roadway leading to and from the gatel and at a desired distance from the gate in opposite directions, the distances, however, not necessarily being equal. In placing the actuating members,` the U members 52 are obviously in the line of travel of one set of wheels of vehicles which will approach or leave the gate. The two frame works related respectively to the actuating members 46 and 41 are set up, and the cables 3| and 32r with their interposed springs 36 and 31 are connected from the gate drum 30 in opposite directions to the trip levers 42 and 43 respectively. The latch'cables 15 and 16 are also connected from vthe arms 5| of the actuating members to the latches 1| and 66 respectively.

In operation, as the vehicle approaches the gate, as from'the right, in Figs. 1 or 3, the wheel strikes the U portion 52 of the actuating member 41 forcing this U portion to the left, and through the arm 5| similarly moves the trip lever 42, the

end of the lever moving in the arcuate pathway A downward into engagement with the notch at the lower end of the latch 1| and being held by the latch in such position, the U portion 52 after passage of the wheels being returned to upright p0- sition by the spring 65. Movement of the trip lever 42 correspondingly movesthe cable 3|, this movement being initially absorbed by the spring 36 and by such spring gradually transferred through the continuation of the cable 3| and the spring 3|A to the drum Sil, starting and com` pleting the raising of the gateand holding this gate in raised position so longas the trip lever 42 is held by the latch 1|. After the vehicle passes f the gate it strikes the U lportion 52 of the actuating member 45 forcing that U also to the left,

and through the arm'5l and the cable 15 therefrom to the latch 1|, disengages this latch and allows the trip lever 42 to be returned by the posts, a gate having one end arranged between and extending rearwardly beyond said posts, a
