GATE.

GPECIPlCATION forming part of Letters Patent No. 319,193, dated June 2, 1885.

Application filed October 22, 1884.

To aZZ whom it may concern:

Be it known that I, POLLIE O. CESSNA, of Macon City, in the county of Macon and State of Missouri, have invented a new and useful Improvementin Gates, of which the following is a full, clear, and exact description.

My invention relates to devices for opening and closing gates; and it consists in a combina tion of levers with a rock-shaft provided with a slotted arm, to which the levers are connected by a slide-piece, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side view of a gate with my improvements applied, and Fig. 2 is a transverse section on line w a: of Fig. 1.

The gate A, as shown, is supported by aroller, a, on a track, b, above the gateopening, and at its back end by a similar roller taking on the top rail of the fence; but it maybe hung to slide in any desired manner. On the two back posts, I), a rock-shaft, c, is supported in bearings d, and a rigid arm, 6, on the shaft is attached by a hinge at its outer end to a bar, f, that in turn is hinged to the forward stile of the gate in such a manner that the partial turning of the shaft effects the movement back and forth of the gate by the swing of arm 6. The shaft 0 is also provided witha cross-arm, g, slotted to receive a sliding collar or piece, 71, and the latter is connected by rods c i to the inner ends of the (No model.)

levers k, which are hung by pivots Z on supports projecting from posts I). The levers extend at opposite sides of the gate a suitable distance, and they are either placed at a height to be grasped from a carriage or they may have ropes suspended from their outer ends.

With the gate either open or closed the crossarm 9 is nearly vertical and the slide h is at the lower end of the arm, the levers, therefore, being at their highest position. By pressing down the outer end of either lever the slide it grips the arm 9 and raises it, so that the shaft is rocked and the gate fully opened and closed. This reverses the position of arm 9, so that slide h is at the top, and on the levers being let go the weight thereof carries the slide down to the bottom again and raises the levers to position for again moving the gate.

Having thus described my invention, I claim as new and desire to secure by Letters Patent
