SPECIFICATION forming part of Reissued Letters Patent No. 11,643, dated December 28, 1897.- Original No. 584,092, dated June 8, 1897. Application for reissue filed November 2'7, 1897. Serial No. 659,991.

To all whom it may concern:

Be it known that I, PHILEMON MARKLEY, a citizen of the United States, residing at Girard, in the county of Crawford and State of Kansas,have invented certain new and useful Improvements in Gates for Use on Farms or Elsewhere, of which the following is a specification.

My invention is constructed on the principle of gravity and is operated by means of levers and wires.

Figures 1 and 3 show perspective views of the gate closed, taken from opposite sides, and

the arrangement and operation of the wires. Fig. 2 shows a perspective View of the gate open; and Fig. at, a perspective View of the post A, one side of it being removed so as to show the yoke V and the different pulleys.

To enable others to make and use myinvention, I will describe its construction and operation.

The gate H is constructed either of Wood or metal, with a beam diagonally and permanently attached thereto. This beam (designated as B) is about twice the length of the gate, but may be shorteror longer, and reaches to and through post A, as seen in Figs. 1 and 3, and bears upon roller 7, which when the gate is closed is midway of the beam, or nearly so. When the gate is open, it rests as seen in Fig. 2. This beam is not only a firm brace to the gate, but a fixed part of the same, which never changes position in respect to it, and serves as a guide for it during its travel.

L is a lever-bar for raising and lowering the gate, and is attached to the lower end of yoke V and to post W at a proper height by a bolt, which allows it to turn and give the gate an up-and-down movement with itself. It will be seen that the long end of lever-bar L has a joint attachment to the lower end of yoke V, and the short end is provided with the support S, to which the roller 9" is attached for the support and slide of the gate. This lever-bar has an up-and-down movement only, while the beam 13 hasthis movement and a horizontal movement also.

The post A is made of two pieces, with a sufficient space between for the yoke V to have an easy up-and-down movement and is provided with the necessary slots for guiding the same. The post is also provided with pul leys i, p 19, and 0 for the support ofthe chains in operating the gate, as seen in the drawings. The yoke V is constructed the proper size to contain the rollers a a, placed at a suitable distance apart to admit the easy passage of the beam B. These rollers are journaled in the yoke, and their journals project through the slots of post A, which serve asguides to the yoke. For the operation of the gate the levers t t are connected with both ends of the yoke by wires and chains, the chain J with the upper end and the chains f f with the lower end, as seen in Fig. 4.

The posts a c, to which are attached levers ti, are placed at suitable distances inside and outside of the gate to admit vehicles without their interference with the gates operation.

The diagonal wires y y are connected to levers zftat an equal distance each side of their pivots and secure uniformity in the operation of wires an and n n, by which the gate is operated. j

The wires u u are attached to levers t t in front and to chain J at the rear, which chain passes over roller 71 and is attached to the topof yoke V. It will be seen that chain J is a branched chain, as shown in Figs. 1 and 3. The wires n n are attached to the rear of levers ttand to separate chains f f, which chains pass over rollers 19 p and down and around roller 0 to the lower end of yoke V, as more fully seen in Fig. 3. The ropes X X are for the handling of levers t 25 in opening and closing the gate.

I will now describe the operation of the gate. It will be seen that the wires 11 n, being attached to chains f f, (which chains passrdown and around roller 0 and are attached to the lower end of yoke V,) pulling either of the ropes X X toward the gate will lower the rear end of beam B, throw the gate up in front, and cause it to slide back to its open position, as seen in Fig. 2; and the wires u a, being attached to chain J and chain J to the top of yoke V, pulling either of the ropes X X from the gate will raise the rear end of the same and cause it to slide forward to its closed position, as seen in Fig. 1.

To open the gate, pull the rope toward the gate, and when through pull the rope from the gate to close it.

The great advantage of this gate over others consists in its easy operation, durability, and Wardly-prolonged diagonal brace-bar B, with protection against the obstruction of snow. the lever L, pivoted upon the rear gate-post The gateshavingnohinges orsagging weight, and provided with guide S, and roller 0; a 15 being poised on roller 1" at or near the center supplementary post carrying movable guides 5 of beam B and left free to slide either Way in for brace B, and means connected With these its operation, renders it more durable than guides for together operating both lever L, other gates, and by the means of lever-bar L and the guides, all substantially as set forth. and levers t i all necessary leverage can be A had for raising and lowering the same.
