GATE.

SPECIFICATION forming part of Letters Patent No. 500,050, dated June 20, 1893.

Application filed April 29, 1893. Serial No.472l288. (N model.)

To all whom it may concern:

' Be it known that I, NEWTON JASPER BIsHoP, acitizen of the United States, residing at Sturgis, in the county of Union and State of Kentucky, have invented a new and useful Gate,

of which the following is a specification.

The invention relates to improvements in tilting gates.

The object of the present invention is to simplify, improve and increase the efficiency of tilting gates, and to enable the same to be readily operated by a slight pull.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawingsFigure1 is a perspective view of a gate constructedin accordance with this invention, and shown closed. Fig. 2 is a side elevation partly in section, the gate bemg open.

Like numerals of reference indicate corresponding parts in all the figures of the drawlngs.

1 designates a tilting gate provided at its lower rear corner with journals 2, preferably formed by a shaft extending through the gate, which journals are arranged in bearing openings in the upwardly diverging sides'3v of a supporting frame. The supporting frame is provided with a top cross-bar 4 secured to the upper ends of the sides 3, and extending outward beyond the same, and having fulcrumed on and hung from the extended portions of the top bar 4:, operating levers 5 arranged at an angle. to each other. The operating levers have their inner adjacent ends secured together and provided with a cross-piece or bar 6, which projects beyond the operating levers and is connected by rods 7 with an. oscillating lever 8. The oscillating lever 8 is fulcrumed at its lower end between short posts 9 in rear of the gate, and has its upper end connected therewith by link bars 10 arranged on opposite sides of the gate. The lower endsof the rods 7 are connected with the oscillating lever at an intermediate point .of the latter by a transverse bolt 11 or other suitable means. The upper ends of the link-bars 10 are pivoted to the upper end of the oscillating lever 8 by a bolt 12; and the bolt 14 to a sliding latch-bar 15 at a central point 011 the gate, whereby a light pull only is required to lift the gate. The sliding latchbar 15 is provided at its rear end with a longitudinal slot 16, and is arranged between pieces 17 located on opposite sides of the gate, and forming a way; and a bolt 18 passes through the slot 16 of the latch bar and through the pieces 17. The front portion of the latch-bar is suspended by a cord 19 or its equivalent, which cord has its lower end secured to the latch-bar and its upper end attached to the gate at the topthereof by means of a projection 20. By this construction the latch-bar is adapted to slide without any appreciable friction; and its front end is adapted to engage a recess 21 of a latch-post 22. When the gate is closed, the weight of the oscillating lever, whichis then in an inclined position, is communicated to the latch-bar through the link-bars, and obviates the necessity of employing a spring for shooting the latch-bar.

The outer ends of the operating levers are provided with depending ropes 24 to enable the gate to be readily operated from the ground or from a vehicle or the like.

It will be seen that the gate is simple and inexpensive in construction, that latch springs are dispensed with and that it may be readily opened and closed by a slight pull. The link-bars should be of sufficient length to cause the oscillating lever and the gate to pass simultaneously over a perpendicular position to prevent any dead center.

Changes in the form, proportion and the minor details of construction maybe resorted to without departing from the principle or sacrificing any of the advantages of thisinvention.

WVhat I claim is 1. The combination of a supporting frame, a gate journaled at its lower rear corner on the frame, a sliding latch bar mounted on the gate, an oscillating lever fulcrumed at its lower end in rear of the gate and vhaving its upper end connected with the latch-bar and operating as a weight for the same, and operating levers fulcrumed on the frame and-conneeted with the oscillating lever, substantially as described.

2. The combination of a supporting frame, a gate journaled at its lower rear corner on the supporting frame, and provided with a transverse bolt, a latch-bar mounted on the gate and having its front portion suspended therefrom, and its rear portion provided with a longitudinal slot receiving the bolt, an 05'- cillating lever fulcrnmed in rear of the gate at its lower end, link-bars arranged on opposite sides of the gate and having their upper ends pivoted to the upper end of the oscillating lever, and their lower ends pivoted to the latch-bar at the center of the gate, operatmg levers fulerumed on the supporting frame, and rods connecting the inner ends of the operating levers with the oscillating lever, substantially as described. A

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

NEWTON JASPER BISHOP. Witnesses:

B. LOGSDON, J. MACK THOMPSON.
