GATE.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed May 17, 1907. Serial No. 374,282.

To all whom it may concern:

Be it known that I, GEORGE F. SEIsEn, a

citizen of the United States, and resident of- Port Royal, in the county of Henry and State of Kentucky, have invented certain new and useful Improvements in Gates, of which the following is a specification.

The object of my invention is to provide an automatically-operated gate; and it comprises a post to which the gate is hinged so that it may swing to and fro in each direction without changing the position of the hinges.

In the accompanying drawing, Figure 1 is a perspective view of a gate showing the latter closed. Fig. 2 is a view showing the positions of the triggers and locking devices. Fig. 3 is a side view of the gate. Fig. 4 is a face view of the gate post showing the keeper for locking the gate. Fig. 5 is a view of the end of the gate next the gate post; and Fig. 6 view of the gate post illustrating the side facing the gate.

In constructing my invention I provide a gate post 6 of suitable height, in the front face of which I provide a gain or cut-away portion 7, near the upper end. In this cutaway portion I place the upper end of a ver tically-disposed rod 8, having at its upper end an outwardly-projecting bend 9, and, approximately, midway, a right-angled bend 10 which passes through and is pivoted in the post 6. The lower end of this rod has a weight 11.

On the front face of the post 6 is a vertically-disposed bar 12, pivoted approximately one third of the distance from the bottom, to the post, as shown at 13. The lower end carries a crescent-toothed casting 14, and at the upper end of the bar is a short verticallydisposed slot 15, in which the right-angled end 9 of the rod 8 operates. To the upper end of this pivoted bar I hinge the ends of two operating arms 16, which project out in opposite directions, and at right angles to the position of the gate when the latter is in a closed position. The ends of these arms have a series of holes 17. In one of these holes is placed the upper end of the arm 18, which arm is an extension of the Wheel trigger 19. The end of each arm 16 has a right-angled bend 19. I

The gate 20 has a horizontal locking bar 21 secured in keepers 22, on the sides of the

stiles

23, 24.. The end of the locking bar on the stile 24, is pivoted, as at 25, and adjacent the projecting end of this locking bar, and

secured to the pivoted bar 12, on the gate post 6, is a pair of projections 26, between which the end of the locking bar rests. These projections have inclined surfaces so that when .the pivoted bar moves in either direction one of these projections will engage with the end of the locking bar and thus raise the opposite end and free it from the locking piece 27 on the locking post 28.

It will be seen that the stile 24 of the gate is pivoted at its upper and lower ends to the post 6 by brackets 6 so that the positions of the pivots are not changed, but the gate at all times swings normally on its fixed hinge. A toothed segment 29 is attached to the lower end of thestile 24, and this engages with the toothed crescent 14 on the lower end of the pivoted bar 12.

In order to provide a means for locking the gate when it is open, and to enable the driver to close it or leave it open, a locking trigger 30 is provided beyond each of the regular wheeI triggers 19. These locking triggers may be placed at any desired distance from the triggers 19. One end of a link 31 is hinged to an upwardly-projecting arm 32, and the other end of this link is attached to a hook-shaped catch 33, the hook of which is within operative range of the right-angled bend 19 on the arm 16, so that when the gate is swung in the direction of the moving vehicle the rightangled bend 19 will approach the hook 33 and engage therewith, and thus hold the gate open until the wheel of the vehicle depresses the locking trigger 30 by whichmotion the hook is disengaged and the weight again closes the gate. A spring, not shown, attached to the hook 33, holds it in its normal position. The driver has thus the 0 tion to drive over the locking trigger and c ose the gate or avoid the locking trigger and thus leave the gate open.

When the wheel of a vehicle strikes the trigger on either side of the post, the arm 16 is moved upwardly, thus causing the lower end of the pivoted bar 12 to move toward the trigger thus depressed, and also causes the toothed crescent to swing the gate in the direction of the movement of the vehicle. At the same time one of the inclined projections 26 strikes the end of the locking bar 21, causing its opposite end to rise and thus become disengaged from the locking piece 27, per mitting the gate to swing. The weight 11, having its fulcrum above the pivotal point of the bar 12, is raised a suflicient distance to aflord a considerable pull, and, in swinging downwardly, carries the gate back to its normal position independently of the other trigger.

Vhat I claim as new, is:

1. In an automatically-operating gate, the combination of a post having thereon a vertically-disposed pivoted bar, a pair of oppo- ,sitely-projecting arms, and wheel triggers for opening the gate connected therewith, a pair of wheel triggers for closing the gate connected with a catch and within operative range of the oppositely-projecting arms, a toothed crescent at the lower end of the vertically disposed pivoted bar, means for swinging the bar into a vertical position, a gate hinged to the post, having a toothed segment at its lower end, engaging with the toothed crescent, and means for locking the gate in its closed position.

2. In an automatically-operating gate, the combination of a post having thereon a vertically-disposed pivoted bar, a pair of oppositely-disposed arms, at its upper end, and wheel triggers connected therewith, a rod having a weight connected with the upper end of said pivoted bar, a pair of projecting pieces with inclined surfaces above the pivotal point of said bar, a gate hinged to the post having a toothed segment to engage with the toothed crescent, a horizontal locking bar pivoted at one end to the gate and normally resting between the projecting pieces on'the pivoted bar, and a fixed post having a notched locking piece to engage the locking 35 bar, as set forth.

Signed at Port Royal in the county of Henry and State of Kentucky this 25 day of April A. D. 1907.
