SLIDING GATE.

Specication of Letters Patent. I

Patented April 21, 1908.

Application filed January 11, 1908. Serial No. 410,393.

To all whom it may concern:

Be it known that we, ANDREW J. RUSSELL and WILLARD B. TERRY, citizens of the United States, residing at Stur is, in the county of St. Joseph and State oA Michigan, have invented a new and useful Sliding Gate, of which the following is a specification'.

This invention relates to sliding gates and more -particularly to means whereby a gate of this character can be operated by a person seated within a vehicle adjacent thereto, the operating mechanism being simple, durable and eflicient and of such character that it can be readily placed in position.

Another object is to provide mechanism of this character in which friction is reduced to the minimum, thus proportionately facilitating the action of the parts.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully de-` tuting one of the gate posts and 2 constitutes the other gate post, the same being preferably formed with parallel retaining cleats 3 between which the end of the gate is designed to extend when-closed. Secured to the standard 1 and to one or more fence posts 4 disposed in the rear thereof or beyond it is a supporting beam 6 having a plu'- rality of outstanding studs 6 to which is bolted or otherwise fastened an elongated metal strip 7 constituting the rail used for supporting and guiding the gate.

The gate may be of any preferred construction and the top rail thereof preferably extends beyond one end of bar 9 of the gate to form an arm 10. Thisfarm may be provided with a brace'll so as to hold it' rigidly beyond the gate. Secured to the rail 8 adjacent the upper end of the bar 9 is a yoke 12 the lower end ofwhich extends at right angles therefrom as indicated at 13 and un-v der the rail 8. This yoke is fastened to said yoke 12 and extends under the rail so as to prevent the sheave from lifting therefrom. The construction of these parts has been clearly indicated at Fig. 2. Secured to the rear portion of the arm 10 is an inverted yoke 16 somewhat similar to yoke 12, the upper end thereof being bent over the arm 10 as shown at 17 in Fig. 3. A sheave 18 is mounted in this yoke and designed to bear upward against the lower edge of the rail 7 and a retaining pin 19 extends from the arm 10 and over the rail so as to prevent said arm from moving downward in relation to the rail.A

Arranged longitudinally upon the top rail of the gate 8 is a slotted retaining strap 2() and extending loosely through this strap is the upper portion of an operating lever 21, the lower end of which is pivotally connected to a base block 22 extending laterally from the lower portion of the standard 1 and under the gate, said block being preferably recessed in its upper face as shown at 23 so as to guide the lower portion of the gate in its movements. A weight 24 is secured to the upper end of the lever 21 and extending from said lever at an intermediate point is a link 25. A push bar 26 is pivotally connected to lever 21 close to the weight 24 and above stra 20 and is also pivotally connected to tfi of the gate.

A beam 27 is mounted upon the upper end of standard 1 and at right angles to the gate and secured lto this beam directly above the gate is a guide plate 28 having openings 29 therein designed to receive chains, cables, or other flexible devices 30 extending in opposite directions from sheaves 3 1 mounted upon the beam and above plate 28. These flexible devices 30 extend longitudinally of the beam and over sheaves 32 disposed adjacent the ends thereof and theterminals of the flexible devices extend downward through apertured e upper portion of the end bar 9 v guide Vplates 33 and are provided with.4

formed along the upper portion of the beam 27 and overhangs the sheaves so asto shield the sheaves and the parts mounted thereon.

Should the gate be closed the same can be readily opened by pulling downward either one of the weighted chains or cables 30. This will cause link 25 to pull up lever 21 and when said lever assumes a vertical position it will be swung by gravity downward and away from the post 2. As the lever is connected to the gate by means of link 26 this operation thereof will cause the link to push the gate longitudinally and the two sheaves 14 and 18 will travel along rail 7 and permit the gate to move with little friction. To close the gate either chain or cable 30 is again pulled downward with sufficient force vto swing lever 21 back to its original position,

this operation of the lever pulling on the link 26 so as to slide the gate into closed position. Importance is attached to the fact that motion is transmitted from the lever to the gate through a push bar or link 26 because the elimination of a vast amount of friction thus results and the operation of the gate is rendered more easy and efficient than where the lever is utilized to bear directly against a portion of the gate as heretofore.

It will be noted that it is not necessary with this apparatus to provide a gate of complicated construction. As a matter of fact the operating mechanism can be readily applied to any ordinary sliding gate simply by providing an arm l0 at one end thereof and applying to the gate the various parts of the apparatus, none of which necessitates the changing structure of the gate. The beam 5 not only serves to support the rail 7 but also acts as a brace connecting the standard 1 with oneor more fence posts.

What is claimed is:

l. The combination with a standard and a rail extending beyond it of a sliding gate supported by the rail, a weighted actuating lever having a fixed pivot, a link pivotally connected at its ends to the lever and gate respectively, a beam supported by the standard and at right angles to the gate, sheaves thereon, iiexible means supported by the sheaves and connected to the lever for shif ting said lever past its center of gravity to move the gate into open or closed position, and a shield upon the beam and overhanging the sheaves and the ilegible means thereon.

2. The combination with a standard and a rail extending therebeyond; of a sliding gate supported by the rail, a longitudinal retaining device upon the gate, an actuating lever having aHiXed pivot, said lever extending loosely between the gate and the retaining device, a weight at the free end of said lever, a link pivotally connected at its ends to the lever and gate respectively, and means carried by the standard for actuating the lever to swing the weight past its center of gravity to move the gate into open or closed position.

In testimony that we claim the foregrnng as our own, we have hereto aliixed our signatures in the presence of two witnesses.
