i SWINGING GATE.

SPECIFICATION forming part of Letters Pat-ent No. 546,580, dated September 17, 1895.

Application filed May '7, 1895. Serial No. 548,431- (No model.)

To aZZ whom it may concern:

Be it known that I, AARON F. COGHILL, acitizen of the United States, residing at Auburn,

in the county of Logan and State of Kentucky, have invented new and useful Improvements in Swinging Gates, of which the following is a specification.

This invention relates to swinging gates, and particularly to that class thereof known as hand-lever openers.

The object of my invention is to provide improved and simple mechanism whereby the gate may be opened and closed from either side thereof withthe expenditure of but slight force and in an expeditious manner, and to improve and simplify the construction and render more efficient the operation of this class of mechanism generally.

To these ends Inyinvention consists in the novel features and in the construction and arrangement hereinafter described, and pointed out in the claims following the description, due reference being had to the accompanying drawings, forming a part of this specification, wherein- Figure 1 isa perspective view of my improved gate. Fig. 2 is a detail plan view of a portion of the operating mechanism, the dotted lines showing the position of the trippinglever immediately before tripping the gate-` latch. Fig. 3 is a similar view showing the gate open, the dotted lines showing the position of the tripping-lever at the moment the gate has been fully openedjand Fig. 4 is a detail view of one of the hand-levers.

Referring to said drawings, the numeral 1 indicates the hinge-post and 2 the latch-post, the gate 3 being hinged to the post 1. At one side of the roadway I arrange anauxiliaryl latch-post 4, provided with a keeper 5, and a similar keeper 6 is secured to the latch-post 2. Pivotally secured to the gate 3 is one end of a latch 7, the free end of which is adapted to engage the keepers 5 and 6 and hold the gate in both its closed and open positions.

Secured to the panels of the gate by clips 8 is a bent arm 9, Vwhich at its other end is bent up at a right angle to form a journal l0,` and over said journal is arranged one end of an arm 11, which at' its other end is journaled on a pintle 12, secured in the top of the hingepost 1; Journaled upon the journal 10 is the tripping-lever 13, consisting of a metallic arm slightly bent, as shown, which is pivotally connected to said journal 10 by heading down the latter, as is more clearly shown in Fig. 1. Tooneend of the tripping-lever 13 is connected one end of a wire 14, the other end of said wire being attached to a loop 15, and said loop is in turn connected by wires 16 and 17 to the gate: latch 7 and an eyebolt 18, fastened in the upper front end of the gate. To the opposite end of said tripping-lever 13 are secured the ends of two wires 19 and 20, the other ends of said wires being secured to the opposite-ends of hand-operated levers 21 and 22, the other two ends of 'said levers being connectedv by a diagonal wire 23. Each of the levers 21 and 22 consists of a head 24, pivoted in an approximately vertical position to a post 32, arranged at the side of the'roadway at a suitable distance upon each side of the gate, and rigidly secured to said head is a shank portion 25, to the free end of which is loosely hung a rigid handle 26. With a view to rendering and maintaining said levers perfectly rigidi pass two wires 27 through an aperture 28, formed in the shank portion 25, and loop the other ends of said wires about the opposite ends of the head 24, and then twist said wires until they are drawn perfectly taut, thus bracing the head and shank portion of said lever together in the most rigid manner. By leaving loops 29 in said wires they may from time to time, by the insertion of a suitable tool, be tightened to compensate forany shrinkage or wear that may occur in the levers, and by forming loops 30 in the'ends ofthe wires a convenient means is provided for the attachment of the operating- wires 19, 20, and 23.

The operation of the'mechanism above described is as follows: Let it be assumed that the gate is closed, as shown in Fig. 1, and that it is approached by a team driven'in the IOC direction of the arrow 31.-l The driver of the ver 22 upon its pivot in the opposite direction. As the lever 22 is oscilla-ted, it draws upon the operating wire 19 and starts to swing the tripping-lever 13 in the direction indicated by the arrow in Fig. 2, the position of said lever before any movement has taken place being indicated by dotted lines. As said lever 13 is rocked upon its pivot, it draws upon the wire 14 and tends to cause said wire and the wire 17 to assume the same straight line, thus drawing the wire 16 up vertically and lifting the latch. When the tripping-lever has assumed the position indicated by tull lines in Fig. 2, the latch will have been raised entirely from engagement with its keeper, and the continued oscillation of the trippinglever will then exert a direct pull upon the front 33 of the gate through the medium of the wires 11 and 17, the force exerted to open the gate being thus applied at a point remote from the hinges of the gate, which, in connection with the leverage obtained by the lever 13 and the operating-handle, will enable the gate to be opened with little power. This movement operates to swing the gate open until the parts have assumed the position shown by dotted lines in Fig. 3, at which time the gate will have been swung entirely open, causing the latch to engage the keeper 5 and hold the gate open. After driving through the gate the driver grasps the handle of the lever 22 and raises the shank portion of said lever and rocks the latter. The lever 21, through the medium of the diagonal wire 23, is thus rocked in the opposite direction, and the wire 2O will then operate to oscillate the tripping-lever 13 to the position shown by full lines in Fig. 3 and raise the latch in the manner before described and release the gate, and as the tripping-lever continues to oscillate the wire 14 will be drawn taut, and said tripping-lever will then operate through the medium of the arm 9 to swing the gate to its closed position. It will be noted that in both opening and closing the gate the tripping-lever in its initial movement operates to draw upon the wire 1.4 and raise the latch, and that after the latch has been raised and said wire becomes taut the tripping-lever is held rigid by the wire 1l and will then operate as it is oscillated upon its journal to swing the gate open or closcd,as the case may be. It desirable a greater leverage may be afforded the lever 13 by attaching the wire 14E thereto at a point, as at 36, instead of to the end thereof, thereby changing the relative proportions of the two ends of the levers and changing the leverage in a manner that will be obvious. It will be noted that all the operating parts are arranged upon that side of the gate which is the rear side when the gate is open, and said parts are thus ettectually removed from all danger of being broken or disarranged by contact with vehicles or heavily-loaded wagons passing through the gateway.

Having described my invention, what I claim is- 1. In aswinging gate, the combination with a bent arm carried by the gato and bent up at its upper extremity to form a journal 10, and an arm 11 secured to the end of said bent arm and pivotally secured to the gate post, of a combined tripping and operating lever 13 journaled upon the journal 10, a gravity latch 7 pivotally connected to the gate for locking the latter in both its open and closed position, tripping mechanism operated by the initial movement of said lever in either direction for raising the latch, rocking hand levers 21, 22, pivotally secured to supports arranged upon opposite sides of the gate, a wire 23 connecting the upper end of one of said levers to the lower end of the other lever, and operating wires 19 and 2O connected at their adjacent ends to the lever 13, and at their opposite ends to the opposite ends of the levers 2l and 22, substantially as described.
