GATE.

SPECIFICATION forming part of Letters Patent No. 408,351, dated August 6, 1889. Application filed April 27, 1889. Serial No. 308,806 (No model.)

To all whom it may concern:

Be it known that l, LAFAYETTE \V. LOUGH- ARY, a citizen of the United States, residing at Monmouth, in the county of Polk and State of Oregon, have invented a new and useful Gate, of which the following is a specification.

This invention relates to gates of that class usually employed on farms across roadways, where it is desirable to open the gate from horseback or from a vehicle without dismount ing or alighting, and after passing through to close it again.

The invention consists of a swinging gate, a latch for holding the same in closed or in opened position, levers for opening or closing the gate from either side, and cords or chains connecting said levers with the gate and with the latch thereon, all as will be fully hereinafter described.

In the appended drawings, Figure 1 is a perspective view of my improved gate complete, shown in its closed position Fig. 2 is' a plan View thereof, showing the gate open. Fig. 3 is an elevation of the gate proper, the Fig. 4: is an enlarged detached front elevation of the pulley and bracket, and Fig. 5 is a central vertical section of said pulley.

The same letters of reference are applied to similar parts throughout.

The letter A designates the main post, to which the gate proper B is hinged, A the latch-post, and A A the leverposts, of which there are two. The latch-post carries a main catch a, beveled in both directions, as shown in Fig. 2, and in the gate 13 is a horizontally-sliding latch-bar O, pressed normally outward from the hinge-bar b by a spring 0. An arm D is pivoted at (Z to the gate and at its lower end (at d) to the latch-bar O.

Each lever-post A carries a catch a beveled in one direction, so that the end of the latchbar 0 will ride thereon and spring into said catch when the gate is swung open. Near the upper end of each post- A one arm of an L-shaped lever E is pivoted, the other arm standing normally in a nearly-horizontal position and projecting away from the gate alongside the road. A diagonal brace e connects the two arms near their elbow'to afford greater strength.

Upon the top of the rear vertical bar 1) of the gate is mounted a flat bracket F, braced by one or more braces f, and on this bracket is pivoted on a vertical pivot a pulley G. (Shown more clearly in Figs. 4 and 5.) This pulley has two complete peripheral grooves g near its upper end and around its center, respectively, and in its lower edgein front and in rear are arc-shaped recesses 71, engaging pins orstuds H in the upper face of the bracket F. Cords or chains I extend from the elbows of the levers E and pass in opposite directions to the rear of and half-way around said pulley, being attached to pinst' in the front face thereof. Although I have shown and described and in fact prefer two grooves g in the pulley, wherein the cords Irun separately, yet one groove and one cord will suffice, the latter being carried halfway around the pulley, secured to a single pin 1' in its front face, and then continued on around the pulley and led to the other lever. In this case, however, the cord would chafe on itself at the rear of the pulley and soon wear out, whereas if two grooves are employed such wearing will not occur. At quartering-points y' on said pulley near its lower end are secured two other cords J, which are led thence forward along the upper edge of the gate over and around a pulley Z), journaled in the upper end of the front vertical. bar B of the gate, and thence back to the upper end of the latch-operating arm D, all as clearly seen in the drawings.

The operation is as follows: The gate being closed and latched, if now an equestrian ap proaches along the road from either side and desires to pass through, he depresses the free arm of the lever E. The result is a tension on the cord I, connected to said lever, which tension first turns the pulley G slightly on its pivot2. e., to the limit allowed by the recesses h and studs H-drawing on one cord J and releasing latch-bar C from the main catch tension on cord I and the additional force exerted by a further depression of lever E continues the rotation of the pulley l, the ends of whose recesses 7r are now exerting a conhen this has taken place, the pent-up IOO siderable torsional force on the studs H, and the gate is swung forcibly open to the position shown in Fig. 2, when the latch-bar C automatically engages the catch a and holds the gate open. The operator now drives through. When on the other side, he depresses the free end of the other leverE. The result is precisely similar, excepting that the gate being now latched in open position the latch-bar C is first disengaged from the catch a by the force exerted, after which the same force continued closes the gate, it latches automatically, and the operator travels on.

The particular advantages of my invention are that the gate never remains unlatched either in open or closed position, swinging in the wind, or liable to be opened by swine, sheep, or other cattle, as is the case withmany farm-gates now on the market; als0,'it opens from the operator, thereby not necessitating his stopping to operate it, especially if the lever-posts A be set at a considerable distance from the gate. Again, the levers E may be quite high and within easy access of an operator 011 horseback or in a vehicle, as pedestrians can operate the latch-bar 0 directly by hand. At the same time the device is simple, cheap, reliable, positive, and not likely to break or get readily out of order.

WVhat I claim as new and as comprising the salient points of my invention is- 1. The gate 13, having a bracket F on its rear vertical bar, and the latch-bar C in said gate, in combination with the pulley G, pivoted on said bracket, said pulley having arc-shaped recesses h, engaging studs II in said bracket for the purpose set forth, cords J, connecting said pulley with said latch-bar and adapted to unlatch it, cords I, wound around said pulley in opposite directions and led therefrom, and levers for drawing 011 said lastmentioned cords, substantially as described.

2. The pulley G, having the grooves g, with pins 2' in the front face thereof, and the arcshaped recesses h, in combination with the gate B, the bracket F thereon, to which said pulley G is pivoted, studs H on said bracket engaging said recesses h, the latch O, the cords J, connecting said latch to side points of said pulley, levers E, and cords I, wound in opposite directions around said pulley within said grooves and attached to said pins, the whole adapted to operate substantially as described.

3. The latch-post A, carrying the two-way latch a, the lever-posts A carrying the oneway latches a the main post A, the gate B,'

hinged thereto, the spring-operated latch-bar C, sliding in said gate, and the arm D, pivoted to said gate and latch-bar, in combination with the bracket'F on the rear vertical bar of said gate, the studs H on said bracket, the pulley G, pivoted on said bracket and having arc-shaped recesses h, engaging said studs, the pulley b, journalcd in the front vertical bar of said gate, the cords J, leading from the free end of said arm D around said pulley l) and connected to opposite sides of said pulley G, the levers E, pivoted to said lever-posts A and the cords I, leading from said levers and wound in opposite direotions around said pulley G, the whole constructed and operating substantially as hereinbefore described.

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