GATE AND ornre TING new NS rnnnn on.

T 0 all who-m it may concern:

Be it known that l, CLYDE C. Coon, citizen of the United States, residing at Sheridain in the county of Sheridan and State of \Vyoming, have invented certain new and useful Improvements in Gates and Operating Means Therefor, of which. the following is a specification, reference being had to the accompanying drawings.

This invention relates to gates, and particularly to means for opening and closing gates.

The general object of the invention is to provide a gate which is mounted upon a track for lateral movement with reference to the road, and provide very simple means whereby the gate may be shifted to its open position or shifted to its closed position by means of cables disposed in convenient position to the operator.

A. further object is to provide a construction of this character wherein the track is a tilting track that is pivoted midway of its ends, so that after the gate has been started either toward its full open position or toward its fully closed position, the weight of the gate will cause the track to tilt downward at that end toward which the gate is moving so that the gate will then run by gravity down the track until it is fully opened or fully closed.

A still further object is to provide means under these circumstances which will hold the gate in either its opened or its closed positions.

Other objects have to do with the details of construction and arrangement of parts as will appear more fully hereinafter.

My invention is illustrated in the accompanying drawings.

Figure l is a perspective view of a gate constructed in accordance with my invention and showing the position of the parts with the gate closed;

Figure 2 is a fragmentary detail elevation of the upper portion of the gate operating mechanism showing the manner in which the gate is operated;

Figure 8 is an end elevation of the construction shown in Figure 2.

Referring to these drawings, it will be seen that there is disposed at one side of the roadway a pair of upright posts 10 which may be connected at their upper ends in any suitable manner and pivoted between these upright posts and extending laterally in opposite directions approximately the length of the gate is the track 11. This track is pivoted at 12 and is formed at its middle with a depressed portion 13. The ends of the track operate vertically in posts 14 which are formed at their upper ends with vertical slots or openings 15, between which. the free ends of the track are guided.

The gate 16 is carried by hangers 17, the upper ends of these hangers carrying wneels 19 and 19 which operate upon the track. The gate of course. operates between the posts 10 and is freely slidable along the track. Ylhen the gate is closed the wheel 19 engages in the depression 13 and when the gate is opened the wheel 19 engages in this depression, thus holding the gate from accidental movement from either its closed or its open position.

Pivoted upon the upper ends of the posts 10 and between the posts is a double bell crank lever 20 pivoted at 21 and having a dow. wardly extending arm 22 which is preferably formed with two oppositely and downwardly curved extremities which extend down into the depressed portion 13 of the track. Mounted upon the uprights 10 below the track are outwardly extending hangers or supports 23 carrying pulleys 24:. Attached to each arm of the lever 20 are chains or other flexible connections 25 and 26. These extend downward through the pulleys 24 and then downward to a position on each side of the gate and pass over pulleys 27 mounted upon posts 28. There is one of these posts disposed on one side of the gate and another post on the opposite of the gate. The chains or flexible connections from one end of the lever 20 Jess downward onto opposite sides of the gate while the chains 26 from the opposite end of the lever pass down to opposite sides of the gate. The chains 25 are'for the purpose of opening the gate. The chains 26 are for the purpose of closing the gate.

With this construction, it is obvious that assuming the gate is closed, as shown in Figure 1, then a pull upon one of the chains 25- will depress the end of the lever 20 to which the chain is connected. This will cause the arm 22 to move to the dotted line position and lift up on the wheel 19 and shift the gate toward the left in Figure 1. as soon as the wheel 19 has been lifted out of the recess 13 and the gate has been slightly shitted to the left, the track will be OVG-lbfilililCQt and tilted downward at its l "1 end and as consequence the gate will run ireni its close to its open position. This w ll l '1' wheel 19 into the recess 13 and ob. this wheel will be on the right hand of the depending arm of the lever 20. the person has passed throiwh the gate one of the operating cables 26 i milled which will shift the arm 22 to the right'i l, lifting the wheel .19 out of the de- 13 and startin the gate toward and as soon as .ne gate has moved sl ward the right it will cause the do the right hand end of the t y will move downward by grim it y right hand end until the It will be seen that w: 1 only a slight effort has to be applied by the person to open or close the gate in order to start the gate toward its open or closed pom. tion and that then the gate rolling down the tilted track will autoin' iicali move without the exercise of any short to its open or closed position. lit will likewise be noted that when the gate has arrived. at its fully open or its fully closed position, ne of the wheels will rest in the depression 122, while the other wheel will be on a level with the first named wheel, due to the downward tilting of the track, so that the gate is thus at all times held in a horizontal position.

I obviously'do not wish to be limited to the details of construction and the detailed arrangement of parts, as it is obvious tnat these may be changed in 1 any ways without departing from the spirit or the invention.

ll claim 1. A gate construction or the character described comprising a vertical member, a track pivoted thereon and er-ztending on each side of the vertical member, the traclr having a depression at its pivotal center, a gate havin wheels running on said track, one Oli'SElld wheels normally resting within the depressed portion of the track, means limiting the downward movement of the ends of the track, and manually operable means for lilo ing the gate and one of said wheels from the depression and starting it along said track.

2. In a gate structure, an upright member, a track having its middle portion depressed and the track being pivoted to said upright member at its middle, wheels operating along the track hangers depending "from the wheels, a gate mounted upon said hangers, means limiting the downward movement of the track at its outer ends, a vertical lever pivotally mounted above the track at the middle thereof and having a depending arm adapted to engage the wheel of the gate which is in said depression, and manually slots to thereby limit the operable means for oscillating said lever in one direction or the other.

3. In a gate structure, a post, a track having its middle portion depressed and pivoted to said post, the track extending in opposite directions from the post, means for limiting the downward movement oi both ends of the track, a "l -shaped lever pivoted at its upper e d to said post and having a depending rm, a gate, hangers supporting the gate and hav wheels operatii on said track, one said wheels normall resting in said deased portion of the traclz, an oscillation :he i -shaped lever causing its arm to age the wheel which is in said depression r said wheel onto the track and imgate toward one or the other end of i e traclr, and manually operable means for oscillating said lever.

i. in a gate structure, a post, a track having its middle portion depressed and pivoted to post, the track extending in opposite directions cm the post, means for limiting the downwai l movement of both ends or the track, a 'l -shaped lever pivoted at its upper end to said post and having a depending arm,-

gage the wheel which is in said depression and lift said wheel onto the track and impel the gate toward one or the other end of thetrack, and a pair of flexible connections depending from each end of the lever, one 01" the flexible connections being disposed on one side ofthe gate and the other on the other side of the gate.

5. gate structure of the character described comprising a pair of vertical posts, a track having a depressed middle portion and pivoted between said posts at its middle, posts disposed beneath the ends of the track and vertically slotted to permit the ends of the track to be depressed into the downward move ment of the ends or the track, a gate adapted to move between said posts, hangers supporting the gate, wheels carrying the hangers and operating on the track, a T-shaped lever pivoted between said posts above the middle of the track and having a depending arm adapted to engage that wheel oil the gate which is disposed in said depressed portion, an oscillation of the lever acting to lift the wheel out of the de Jressed portion and impel the gate along the track, and manually operable means disposed on each side of, the gate whereby the lever may be tilted.
