AUTOMATIC GATE.

Application filed December 29, 1925.

This invention relates to an improvement in gates designed to be operated, that is, both open and closed, from a comparatively remote point, the operating means being arranged so that it may be conveniently grasped and actuated by the occupant of a vehicle without the necessity of leaving the vehicle.

The improved gate is adapted for swinging in either direction, and is provided with a latch by which the gate is automatically held in closed position, there being a stop arranged to cooperate with the keeper to prevent the gate from riding to and beyond latch position in closing.

The invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view showing the gate and operating means as arranged ac cording to the present invention.

Fig. 2 is a view in elevation of the gate post, showing particularly the stop cooperating with the keeper.

Fig. 3 is a broken plan of a detail.

The gate 1 which may be of any desired construction, form, and material, is mounted for swinging relation to a. post 2, and provided at the opposite end with a latch 3 arranged to cooperate with a keeper 4 mounted on a post 5 and provided with inclined guides 6 so that the latch may be guided into the keeper in the swing of the gate in either direction. On a line transverse the gate and in rear of the post 2, on which the gate is hung, there is arranged a series of uprights 7 arranged in a line and extending some distance in both directions beyond the gate. The terminal posts 7 are somewhat higher than the intermediate posts and a guide line 8 is terminally secured to the end posts 7 and passes through guides 9 on the intermediate posts. This guide line is presumed to be comparatively tight between the terminal posts, and if desired, means such as a turnbuckle, not shown, may be utilized to maintain desired stretch of the guide line. A lever bar 10 is secured to the upper edge of the gate and extends rearwardly thereof, projecting below and having its free 'end disposed beyond the guide line. A latch operating connector 11 is connected to the latch 3 in advance of the pivot 12 for such latch, a spring 13 being utilized to normally hold the latch in operative position. Operating cords 14 are provided at intermediate points with guid- Serial No. 78,207.

ing eyes 15 which slide freely on the guide line 8. These operating cords pass through guides 16 fixed on arms 17 extending from the terminal posts 7, and may, if desired, be terminally provided with convenient hand grasping members 18. The inner ends of the operating cords 14 pass around a guiding sheave 19 carried by a bracket 20 secured on the free end of the lever 10, the terminals of each of the operating cords being then con nected to the free end of the latch operating connector 11.

Obviously a pull upon either of the handles 18 will first draw the operating connector 11 longitudinally of the gate to raise the latch free of the keeper 4 and thereafter swing the gate into open relation, thereby tightening the remaining operating cord so that after passing through the gate the operator may actuate this remaining cord to close the gate.

As it will be apparent that the gate in swinging to closed position moves under considerable speed, it may be that the latch 3 will ride into the keeper and out again, permitting the gate to continue to an open position in the opposite direction. To prevent this movement of the latch, I provide a stop 21 of triangular form secured upon the post 5 immediately above the keeper with the space between the downwardly inclined edges of the stop and the keeper just sufficient to permit the latch to ride into keeper engaging position. Obviously as will be plain from Fig. 2, the stop interrupts the movement of the latch and compels the same to drop into the keeper, thus checking the movement of the gate and compelling it to come to rest in a latch position.

The arrangement of the parts is such that the handles of the operating cords may be conveniently grasped by a person in the vehicle without the necessity of such person leaving the vehicle so that the gate may be opened and closed without any material delay, and thus permit the driver to proceed. The projection of the lever 10 beyond the gate provides sutlicient leverage to insure an easy movement of even a heavy gate.

Claim:

In combination with an automatic gate, a post on which the gate is pivotally supported, a series of posts arranged in alignment with the pivot post and at right angles to the gate when closed, the respective end posts of such series of posts being forma pulley carried by said bar, an operating cord passed over said pulley, a gate latch, a connection between the operating cord and said latch to-operate the latchinthe move- 10 nient of the cord, guiding means carried by the cable to receive the operating cord, and means carried by the extensions of the end posts to receive the terminals of the operating co-rd,- whereby the cord is held in line in operation at the rear edge of the gate With the terminals thereof inwardly from such line to permit convenient operation.

In testimony whereof I afiix my signature.

EDWARD L. MANSTAD.
