SPFGIFECATION forming part of Letters Patent N o. 727,584, dated May 12, 1903. Application filed November l. 17902. Serial No. 129,708. (No model.)

To all whom, it vta/ 7] concern:

Be it known' that I, JAMES WILLARD BROWN, a citizen of the United States, residing at Osceola, in the county of Mississippi and State of Arkansas, have invented a new and useful Gate, of which the following isa specification.

The invention relates to improvements in gates.

The object of the present invention is to improve the construction of lswinging gates and to provide simple, inexpensive, and eficient means for enabling a gate to be opened and closed from a distance to avoid dis` mounting from a horse or vehicle.

Another object of the invention is to enable a latch-bar to be operated automatically and to cause the mechanism for actuating the gate to lock the gate in its closed position in order that the separate latch-bar may be dispensed with when desired.

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 drawings, Figure 1 is perspective view of a gate constructed in accordance with this invention and shown closed. Fig. 2 is a sectional elevation of a portion of the gate, illustrating the position of the lever and the link-bar when the gate is open. Fig. 3 is an enlarged detail view, illustrating the construction of the inner adjacent ends of the lever and the link-bar.

Like numerals of reference indicate corresponding parts in all the iigures of the drawings.

l designates a swinging gate of any desired construction, hinged to a post2 and connected with an upright 3 by an oscillating lever 4 and a link-bar which when the gate is closed, as illustrated in Fig. 1 of the accompanying drawings, form a straight brace capable ot' locking the gate in a closed position. The upright is situated a short distance from the hinge-post 2 land is preferably su pported by suitable bracing-bars connecting it with the hinge-post.

The oscillatingI lever has-its outer end 6 bent at an angle to form. a journal and arranged in a bearing '7 of the upright 3, and

the inner end of the lever is provided on its lower face with a depending eye 8, situated a short distance from the extreme end of the lever and linked into a perforation 9 of .the bar 5, whereby the inner ends of the lever and the bar are caused to overlap. The inner overlapping ends of the lever and the bar are reduced and flattened, and the bar is provided with a shoulder 10, formed by recessing its upper face, and by this construction the parts are interlocked when in alinement and are securely held against downward sagging in order to form a brace for locking the gate when closed.

The depending eye of the lever and the perforation of thelink-bar form a hinge connection,`and the bar and the lever provide a toggle connection between the gate and the post or upright 3. The lever is provided at one side with a pin 11, to which is connected a link or rod 12, and the latter has attached to it operating-ropes 13, whereby the hinged ends of the lever and the'bar are swung upward to cause the gate to open. The momentum of the gate in opening carries the oscillating lever beyond a perpendicular position, and when the gate is'open, as illustrated in Fig. 2 of the accompanying drawings, the parts assume the position shown and are adapted to be swung upward by the operating-ropes, which have an equal pull in4 opening and closing the gate.v

The operating-ropes extend through a double pulley secured to an armla, projecting horizontally from the upright 3, and thence extend to and depend from similar arms 14, attached to and projecting horizontally from uprights 15.l The drawings show but one of these uprights 15; but it is tobe understood that in practice there will be two of the uprights, situated one at each side of the gate and at a suitable distance therefrom to p ermit the gate to swing to an open position without contacting with a horse or vehicle when operated by a person on horseback or in a vehicle.

The gate may, if desired, be'provided with a pivoted latch-bar 16, arranged to engage an inverted keeper 17 and connected at its inner end by a rod 18 or the-like with the upwardlyswinging link-bar 5. As the lever and the ICO link-bar swing upward the inner end of the latch-bar is simultaneously raised to disengage the latch-bar from the keeper 17.

1t will be seen that the means for opening and closing the gate are simple and inexpensive in construction and positive and reliable in operation, that they are capable of being readily applied to any ordinary Aswinging gate, and that they are adapted to operate the latch automatically and also to serve as a latch for locking the gate and to enable the ordinary latch tobe dispensed with.

Changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

VWhat I claim is- 1. The combination with a swinging gate, of an upright located at one side of the rear end of the same, a bearing associated with the upright,-a swinging lever havingr one end bent at an angle and journaled in the bear ing, said lever being provided adjacent to its other end with a-depending eye, a pin associated with the. lever between the eye and journal, a link-bar having'one end hinged to the gate and provided at its other end with a perforation to receive the eye of the lever, said link-bar and lever having their meeting ends overlapped with the end of the lever seated in a recess formed in the link-bar, a link-rod extending upward from the pin of the lever, and operating-ropes connected with the link-rod.

2. The combination with a swinging gate, of an upright located at one side of the rear end of the same, a link hinged at one end to the gate and provided at its other end with a recess, a swinging lever journaled at one end to the 'upright and pivotally connected at its other end with the link-bar and overlapping the same, with its overlapped portion seated in the recess formed in the bar, a latchbar pivoted to the gate, and a connection between the inner end of the latch-bar and the link-bar.

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

JAMES WILLARD BROWN. Witnesses:

L. A. MORRIS, W. D. HALL.
