UNITED STATES PATENT OFFICE- CALVIN G- LINDSAY, 0F LEXINGTON, ILLINOIS;

To all whom it may concern:

Be it known that I, OALvIN G. LINDSAY, a citizen of the United States; residing at Lexington, in the county of McLean and State of Illinois, have invented a new and useful Gate,

"a side elevation of a gate and its operating mechanism embodying my invention. Fig. 2 is an end elevation of the same.

Referring to the drawings, I designates a supporting-frame comprising a pair of end posts or standards 2, an intermediate post 3, and a top connecting-bar 4., extended between and attached in any appropriate manner to the upper ends of the posts, therebeing sustained by said frame an overhead track or way 5.

Suspended from the track 5 by means of end hangers 6, having at their upper ends antifriction-rollers 7, designed for travel upon the track, is a gate 8, comprising bars 9 and horizontal slats or rails 10, there being pivoted to the gate, respectively at opposite ends thereof,-a pair of latch members 11 12, designed to swing in a vertical plane for engagement with or disengagement from suitable keepers 13, carried, respectively, by the front and rear end posts 2 of the frame, the latches being normally pressed to engaging position for automatic engagement with their eepers by means of springs 14.

Arranged upon opposite sides of the gate at points suitably remote therefrom and in line with the central post 3 is a pair of supports 15, having at their upper ends suitable earings for the reception of a horizontal rotary operating-shaft 16, supported between its ends by a bearing 17, carried by the post 3 said shaft having fixed, respectively, u on its opposite ends a pair of operatingmem ers or crank wheels 18, and etween its ends in alinement with and immediately over the top rail of the gate 8 a winding-drum 19. It is to Specification of Letters Patent. Application filed -Tanuary 22,1904; Serial No. 190,192.

be noted that under this construction the shaft may, through the medium of the crankwheels 18, be readily actuated at points remote from and on either side of the gate, by a person seated upon horseback or in a vehicle and without dismounting.

Suitably coiled around the drum 19 is an operating-cable or its equivalent 20, which extends in op osite directions from the drum through suitable guides 21, carried by the to rail of the gate adjacent to the op osite en s of the latter, and has its termina s attached in some appropriate manner respectively to the latch members 11 12, it being ap arent that as the drum is rotated with the s aft in the manner above explained the cable will be wound thereon in one direction and payed off in the other, thus positively moving the gate to open or closed position according to the direction of rotation of the drum.

During the travel of the gate it will be prevented from lateral oscillation, and thus caused to move steadily and evenly by means of a bearing-roller 22, sustained by a suitable bracket at the lower end of the post 3 inposition to engage the lower horizontal rail 10.

In practice the gate will be automatically locked in its open or closed position by the latches 11 12, respectively, and these latches willthat is, the one which is in active engagement willbe positively released iPatnted June 19,1906.

through the medium ofthe cable 20 at the f beginning of the gate opening or closing aving thus described the invention, what is claimed is- In a gate the combination with an intermediate and end standards, and a track supported by the standards; of a gate, hangers extending therefrom and movably mounted upon the track, latches pivotally connected at their inner ends, to the gate and rojecting beyond the ends of the gate, a coi ed spring interposed between each latch and the top rail of the gate, eyes carried by the top rail of the gate at points between its ends, a shaft journaled upon the intermediate standard and extending to opposite sides of the gate,

' hand-Wheels for rotating the shaft, a drum upon the shaft and between the intermediate standards and the path of the hangers, said drum overlapping and disposed close to the top rail of the gate, and a cable Wound upon the drum and extending over one side of and shielded by the top rail of the gate, the ends 10 of said cable being movably mounted Within the eyes and secured to the latches.
