ISRAEL L. LANDIS, OF LANCASTER, PENNSYLVANIA.

GATE.

SPECIFICATION' forming part of Letters Patent No, 339,903, dated April 13, 1886.

(No model.)

To all whom it, my concern:

Be it known that I, ISRAEL L. LANDrs, a citizen of the UnitedStates, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements'in Gates, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improvements in gates; audit has for its objects to provide a gate that may loe readily elevated to any convenient height, and fastened by means of an adjustable latch; to provide for automatically opening the gate by the draft upon the latch when the bolt is withdrawn from the catch, and to provide an improved hinge to be employed in connection with the gate, and means for holding the gate upon the pintle of the hinge, all as more fully hereinafter specified. These objects I attain by the means illustrated in the accompanying drawings, in which- Figure l represents a side elevation of my improved gate complete, showing the same in a closed position. Fig. 2 represents a vertical sectional view of a portion ofthe gate,taken on the liney y of Fig. l. Fig. 3 represents a vertical sectional view of a portion ofthe gate, taken on the line x x of Fig. 1. Fig. 4. represents a transverse sectional view of the adjustable catch detached; Fig. 5, a sectional view taken at right angles to the view shown in Fig. 4; Fig. 6, a detached view of the upper hinge ot' the gate. Fig. 7 is a side elevation of the gate in an elevated position; Fig. 8, a detached face view of the adjustable catch and gatepost; and Fig. 9 is a top view showing the adjustable wheel.

The letters A and B indicate the respective gate-posts, and C the gate, which is hinged to the post A.

D is a vertical beam, which forms part of the gate, the said beam being slotted vertically for the passage of an adjustable bolt, E, which extends between the vertical beams F, which also form part of the gate. The bolt is provided with a nut, G, at one end, by means of which the beams D and F may be clamped together to adjust the gate, as will more fully hereinafter appear.

The letter H indicates a series of parallel bars, which are pivoted at one end between the beams F, and at the other between similar beams, I, to permit the gate to be raised atan angle when desired. At opposite sides of the said bars H are arranged the oblique bars K, which are pivoted at their upper ends to the upper ends of the beam D, as shown. Near their lower ends the bars K are connected by a screw bolt, L, upon which is mounted a friction-wheel, M, which sets between thelower ends of said bars. The bolt is provided with a elampnut, N, by which the bars may be drawn together and clamped upon the two lower parallel bars, the frictionroller being somewhat less in thickness than the said parallel bars for the purpose. This roller permits the inclined bars to ride with but little friction upon the lower parallel bar when the gate is elevated, thus rendering the operation extremely easy.

The letter l indicates the bolt of the gate, which is arranged to slide longitudinally along the top of one of the parallel rails between thebeams I. The said bolt at one end is pivoted between two bars, R R', which are located on opposite sides of the gate, the bar R being pivoted at its lower end to one of the parallel bars, and the bar R pivoted at its lower end to the opposite side of said parallel bar, as Shown. The bar R' is contracted at a portion of its length, so as to form a spring, and its upper end projects above the upper parallel bar of the gate, and is perforated for the attachment of the operating-cords S. To the parallel bar to which the springbar is pivoted a slotted pawl or dog, T, is also secured in such manner that its free end may bear against the lower portion of said spring-bar, in order to regulate the tension of said bar to give the bolt more or less throw, the dog being adj ust-ably secured by a screw, T.

To the upper end of the beam D is secured a grooved pulley or wheel, U. This wheel at its periphery is provided with an cyebolt, V, through which pass the operatingcords before mentioned, the said cords being carried around the pulley or wheel in opposite directions and extended to each side of the gate. The pulley-wheel may be secured to the lateral head of the upper hinge-section, V, and bracket X, as shown in Fig. 7, or to the lat eral heads of the upper sect-ion, as shown in Fig. 1, in the latter case the bracket X being SLC ICO

dispensed with, and the forward lateral head` of the upper hinge-section taking its place. Both the bracket and hinge are slotted, as shown, and are secured by means of screw bolts and nuts Y to the beams D in such mauner as to be vertically adjustable. The eyesection of the hinge IV is cast in one piece with the horizontal head complete. Below the lower hinge, Z, is located a wire pawl, A', which may be swung under the pintle to keep the gate in position.

The letter B' indicates the adj ustablc catch, .which consists of a rectangular frame of metal arranged to slide upon a vertical bar, C', forming part of the gate-post B. The said frame has pivoted to it a cam-lever, D', one end of which is thickened, so as to bind the frame to the bar C', and thus hold the catch in any position to which it may be adjusted. This is accomplished by depressing the outer end of the lever. rIhe catch-frame has 011 its inner face inclined guides leading to the recesses D', by means of which the bolt is automatically engaged to lock the gate when it closes.

As shown in Fig. l of the drawings, the upper eye-section of the hinge is cast with an elongated eye, E', and a connectingweb, F', which strengthens the hinge and enables it to stand the Vertical adjustment.

The operation of my invention will be readily understood in connection with the above description, and is as follows: Upon pulling upon either of the cords the spring-bar will be first drawn back, releasing the bolt from the catch. Thepulley or wheel will then be rotated, causing the gate to open. To close the gate, the opposite cord is'drawnupon until the gate closes, when it is released and the bolt springs into the catch.

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

`l. Ihe combination, with the vertically-ad justable gate and its clamping-bolt, of the vertically-adj ustable catch and the cam-lever, whereby the catch is held in an adjusted position, substantially as specied.

2. The combination,with theverticalhinged beam, of the upper hinge and Abracket having
