AUTOMATIC GATE.

SPECIFICATION forming part of Letters Patent No. 620,967, dated March 14, 1899.

Application filed February 10, 1898. $erial No. 669,849. (No model.)

tion is to improve upon United States Patent With this and other minor objects in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those. skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in'detail, referring to the accompanying drawing, forming a part of this specification, in which I have illustrated my invention by a view in perspective.

In the drawing, A is a post so constructed that the gate B may swing therein, the lower portion of the gate being hinged in the footblock 0, while its upper end is suspended by .the wires 0, attached to the gate, crossed, and

passed around the lever a at the rounded portion d. The lever a is pivoted within the cap-block b by means of a bolt f, and this lever has shoulders 0' formed thereon for limiting its movement upon either side. An arm g is attached to the post on each side. These arms extend outward and are braced by means of the strips h and carry pulleys k at their outer ends. Over these pulleys run wires or ropes i, which are attached to the lever a at e. The wires '0" have suspended from their outer ends the weights Z, which in practice should be about ten pounds heavier than required to shift the position of the lever a to bring about the movement of the gate, and for convenience a handle an may be secured to each of the wires immediately above the construction.

weights. on the ground. 1

Inpractice when the gate is approached from the side having the weight in its lowered position it is opened by lifting this weight, so as to permit the opposite weight to draw the lever a to the opposite side, and when the gate has been passed it is closed by moving the opposite weight, which will permit the first-named weight to draw the lever to its original position.

Posts may be used instead of the arms 9', and these postsmay be set at a considerable distance from the gate and support the pul leys is, over which the wires run, so as to per mit the opening and closing of the gate from a considerable distance with perfect ease, thus facilitating the separation of cattle, as they may be driven ahead, and when a portion thereof reach the gate the latter may be opened until the proper number have passed through, when the gate may be again closed without the operators moving, and for farming purposes this is of considerable advantage.

Perfect control is always had of the gate, since by simply raising or lowering the weights quickly, the gate can be opened or closed rapidly and hard and by reversing the movement the gate may be checked at any point or permitted to open or close slowly.

It has been found that the gate will readily open or close against a considerable wind, thus avoiding the necessity of handling the same'except through the wires 2', and it is to be noted that no weight behind the gate to counterbalance the same is necessary in-this It is also obvious that instead of the wires 1' rods or strips could be used, but when the gate is to be opened from a considerable distance the wires are preferable. The closed position of the gate is shown in full lines, while the open position thereof is shown in dotted lines. The latch-bar 'n, by which the gate is opened or closed by hand, is here shown as projecting downward, and this is advantageous,since it permits the opening of the gate by persons of small stature and prevents to a large degree the opening of the gate by cattle or horses.

One of the weights Z always rests It is to be noted that my improved gate combines all the advantageous features of the above-named patent,while materially improving thereon, thus rendering the gate more de sirable and durable.

Having thus fully described my invention, what I claim as new and useful is- 1. In combination, a post, a cap thereon, an upright lever pivoted within said cap, a wire passed around said lever and securedat its ends to the outer or swinging end of the gate, and means for shifting the position of the lever, as and for the purpose described. 2. In combination, a suitable post, a cap secured thereon, a lever pivoted within said cap and having shoulders for limiting its movements, a wire passed around said lever and attached to the gate for supporting the weight thereof, and means attached to the upper end of the lever for shifting its position whereby the gate will be caused to open or close, as

specified.

3. The herein-described combination of a gate, a post in which said gate is hinged, a cap carried by the upper end of the post, a lever hinged within said cap, a Wire passed around said lever and attached to the gate, wires or ropes attached to the upper end of the lever, pulleys over which the outer portion of the Wires run, and weights suspended from the outer ends of the wires, as and for the purpose set forth.

In testimony whereof I have hereunto affixed'my signature in the presence of two subscribing witnesses.
