GATE.

SPECIFICATION forming part of Letters Patent No. 361,272, dated April 19, 1887.

Application filed May 19, 1886. Serial No. 102,611. (No model.)

To all whom it may concern:

Be it known that 1 BRIGE B. EDDY, a citizen of the United States, residing at Columbus, 1n the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Gates, of which the following is a specification.

My invention relates to that class of gates known as farm and automatic gates; and the object of my improvements is to provide slmple and effective means for readily opening and closing a gate; as hereinafter described, and specifically set forth in the claim. I attain this object in the manner illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved gate. Fig. 2 is a detail plan view of the operating-lever with the top removed from its head. Fig. 3 is a side elevation of the same.

Fig. 3 is a horizontal section on line :10 w of wheels which gear therewith. Fig. 7 is a side view of the lower hinge.

Similar letters refer to similar parts throughout the several views. r

A represents the gate, which is set between posts B B. From the top of the post B is made to project upwardly a pin, 0, on which 1s loosely pivoted a lever, 0, having a flaring head consisting of two oppositely located metal arms, 0, which project outwardly and forwardly in curved lines, and which are continned to form an outwardly-curved front, 0

Over this head may be placed a metal cover, 0 to prevent the entrance of snow and rain, and thus keep the parts in working condition. The curved metal front 0 is provided onits inner surface with a series of teeth or cogs, adapted to engage with the teeth on a segment of a small cog-wheel, d, mounted on the upper end of a shaft, D, which, extending downward, passes through a metal bearing-plate, 6, projecting from the front side and near the top of the post B, and thence being bent outwardly and downwardly passes through a metal bearingplate, f, made to project rearwardly from the frame of the gate. Immediately beneath this plate f the shaft D is provided with a rear- Wardly-projecting lug, f, the upper surface of which bears against the bottom of the bearing f, and from the lower surface of which, near its rear cnd,'projects downwardly a short pin, f, which rests in a metal bearing-plate, 6, made to project forwardly from the post B. Thus is formed the upper hinge of the gate, the lower hinge being of any well-known form.

From each side of the rear end of the lever 0 extends a wire, 9, to the outer end of which is secured a small chain, 9. These chains, extending nearly at right angles with the lever,

pass around pulley-wheels h, secured to'the rear side of posts H, set at equal distances from either side of the gate-post B, and, passing upward, terminate in short wires 9 which connect with the rear ends of the vertically-swinging-bars z, pivoted in swivel bearings i, projecting from the tops of the posts H. This bar 2', projecting forwardly, has hanging from its inner end a rope or chain, it, of any desired length.

On the inner side of the post B is fixed a metal catch, J, beveled downward toward either side, and having a central upwardlyprojecting tongue, J which forms the partition between two notches. In one of these notches is adapted to rest the end of a latchbar, J, pivoted at its rear end to any convenient point on the gate. Below the catch J, and near the bottom of the gate, is made to project a slightly beveled metal track, over which is adapted to run asmall bearing-roller pivoted to'the gate-frame. By pulling down on the rope i the rear end of the bar 5 is raised, operating to pull the rear end of the lever 0 forward by means of the rods 9 g and chains 9. The forward movement of the lever, communicating motion to the cog-wheel (1, causes the shaft D to be turned back away from the person opening the gate, off its central balance, operating to pull the upper part of the gate backward, thus raising the forward part sufficiently to allow the latch-bar J to escape from the notch in the catch J and the gate to be carried back out of the way until it reaches a position at right angles with its former position, when the latch-bar J becomes engaged with the beveled catch Jiof any wellknown form, made to project from a post set at that point. Below this catch projects a ICO small spring, J of any desirable form, against which the frame of the gate may strike and lessen the jar.

Projecting from the rear end of the gate are small set-screws 7., which, when the forward end of the gate has been raised sufficiently to allow the latch J to clear the notch in the catch J, are adapted to bear against the lug f and prevent the gate from being tilted farther than necessary, and causing it to open by the direct force of the shaft D, and not by its own weight, thus allowing the operator to overcome the force of a strong wind. In other words, the heads of the screws 7., projecting from the rear edge of the gate, come in contact with the lug f of the crank-shaped shaft D at an earlier moment than the body of the gate would if it had no screws, and at a time when the lever G has passed through only a small portion of its arc. and when it can yet travel along are to swing the gate around. The screws fare furthermore preferable to blocks nailed to the rear edge of the gate, as the distance of their heads from the gate can be readily adjusted to make up for the wear of the adjacent parts. In order to close the gate after passing through, the corresponding rope, 11, on the opposite side, may be pulled down, and the lever, by means corresponding with those described, will be pulled in the opposite direction and the gate raised until the latch J'is disengaged from the latch J and swung back to its former position. In case the traveler comes from the opposite-direction from that described, the operation will remain the same, except that the order of pulling the ropes i" will be reversed and the gate swung in the opposite direction.

It is a well -known fact that gates of the usual construction may be opened or unlatched by pressure against the bottom of the gate.

It will be readily seen that by the construction above described pressure on the under side of the gate will cause the bearingfto come in contact with the bend in the shaft D and prevent the gate being raised sufficiently to allow the latch-bar to escape its place in the notch, thus making a permanent lock against live stock. In case the traveler should desire to open the gate by hand, he may readily do so by raising the latchbar J. The bars i i, being supported on swivels of any known form, may be swung back out of the way to allow a load of hay or other large body to pass through the gate.

In order to accomplish the objects above mentioned when a double gate is used, the pin f is continued downward from the bearing 0 in the form of a long shaft,f", and, passing through overlapping bearings 6', projecting from the lower portion of the gate frame and post B, extends below the surface of the ground, and, entering an oblong box, I, has mounted on its lower end a segment of cog-wheel m, the teeth of which are adapted to engage others formed on one side of a bar, a. The second gate, A, is supported on its lower side in suitable bearings,a, made to project from the frame of the gate and the post B, through which passes a shaft, a, corresponding with the shaft f 3 of the gate A, and similarly bent and hinged at the top in bearings a. This shaft a, extending downward, carries on its lower end a segment of cog-wheel, m, adapted to engage with teeth on the opposite side of the bar a, which extends diagonally from the wheel at to the wheel m. This bar a is held in its place against the cog-wheels mm by means of guidewheels 0, mounted on the upper ends of vertical rods fixed to the bottom of the box Z, said wheels being adapted to run against the smooth sides of the bar, each having a flange top, which overlaps the top side of the bar '21, and guide-wheels p, pivoted to the outer ends of arms 1- of the rod q at right angles with the wheels 0, and adapted to run against the under side of the bar a. The gates when closed are latched by means of vertical rods I) b, loosely supported in keepers b projecting from the ends of each of the gates, each of said rods 1) I) being provided with a suitable handle for raising the same by hand. The lower ends of these rods rest in notches. or grooves in the beveled patch I), projecting from the ground, and similar in shape to the catch J on the post B. This double gate may be opened in the manner prescribed for the single gate, the revolution of the shaftf communicating motion through the cog-wheel m and bar a to the cog-wheel m and shaft a, operating to draw the upper part of the gate backward, so that the bar 6 will be disengaged from the notch in the catch b and the gate swung open.

At points between the posts B and II are made to project from the ground beveled catches having downwardly beveled fronts and central notches, into which the bars I) may drop when the gates are open.

I am aware that gates have been provided with a crank-shaft at the hinge, a cog-wheel thereon, and a lever provided with an internal segmental rack, and that said lever has been connected by means of rods with horizontallyswinging levers projecting in the path of carriages, and that racks and pinions have been used to connect a pair of gates, and do not claim said constructions.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination of a gate, its bearing-plate, a crank-shaft carrying a cogwheel on its upper end, and set-screws 7c in the rear of said gate to bear against the crank of the shaft, with the lever 0, having an internal segmental rack, substantially as and for the purpose described.
