GATE.

SPECIFICATION forming part of Letters Patent No. 449,456, dated March 31, 1891.

AApplication filed September 9, 1890.

To all whom, t may concern.-

Be it known that I, FRANK WILLTAMs, of Cisco, in the county of Platt and State of Illinois, have invented a new and useful Improvement in Gates, of which the following is a full, clear, and exact description.

This invention relates to improvements in sliding gates used to close avenues of travel or to bar a passage-way from one field to another, and has for its object to provide an improved device of the character named which will afford an operator in an approaching vehicle means to close a roadway and open the same for travel in either direction, the gate being also adapted for easy movement by direct manipulation from the ground.

To these ends my invention consists in the peculiar construction of parts and their combination, as is hereinafter described, and pointed out in the claims.

Reference is to behad to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the gate in closed adjustment. Fig. 2 is a plan view of the gate closed, some parts being broken away and others in section, taken on the line 2 2 in Fig. l. Fig. 3 is an end elevation of the gate and its supports viewed in the direction of the arrow l in Fig. l; and Figetis a vertical transverse section of the gate and its supports, taken on the line 4 -it in Fig. 1.

The gate A is preferably made of a proper number of elongated rails a, that are retained evenly spaced apart and parallel to each other by the vertical end bar b and side bars c e', the latter-named being secured to the rails at such points on the side of the gate-rails as will retain thelatter assembled to form a rectangular structure.

To stiffen the gate A, two diagonal bars (l CZ are attached to the rails a on the same side with the side bars c c and incline oppositely,i so that all the rails are stayed by their attachment thereto, and a light substantial structure is afforded.

As a means for the vert-ical support of the gate A in a manner thatwill permit said gate t0 be moved longitudinally, two main postsB B are erected parallel to each other. The

main posts B B are separated a proper distance and are situated on one side of a roadway which is to be guarded by the gate A, the post B being nearest to said thoroughfare. On aligning faces of the posts B B similar rectangular frames are secured, each frame consisting of two upright standards ff which are retained parallel and spaced apart a proper and equal distance by the cross-bars g g,the upper cross-bars g being separated from the lower cross-bars g on each frame a distance which will allow the gate A to move freely between the cross-bars named.

`The upper longitudinal rail d. of the gate A is provided with a depending guide-bar a', which extends throughout the length of the rail and rests upon the similar grooved rollers h, that are loosely mount-ed on journal bracket-arms 7L', which latter project from the inner sides of the standards ff at right angles thereto and in the same horizontal plane at such a relative distance above the lower cross-bars g as will retain the gate A free to reciprocate above said cross-bars, as shown in Figs. 3 and 4.

Y From the second rail of the gate A the short guides a2 project and have a loose engagement with the grooved rollers 71, when the gate is moved a sufficient distance, so that said gate will be prevented from sagging at either end of its travel, which would otherwise occur owing to the transfer of the preponderance of the weight of the gate to opposite.

sides of the main posts B B by the opening and closing of the gate. l

Above the upper cross-bars g of lthe gatesupporting frames two similar shafts t' t" are journaled at their ends in transverse perforat-ions in the standards f f', which shafts each afford support for a flanged pulley 7s, centrally secured thereon, and two smallerflanged pulleys m m', that are affixed close to the larger pulley 7o, the two large pulleys beingofequaldimensionsandthe foursmaller pulleys of the same size with regard to each other. The frame-standards f j" are connected in pairs on each side of the gatesupporting f rames, of which they form portions, by two opposite horizontal braces a, which latter are joined near their longitudinal centers by the cross-bar a', on which are located the two IOO similar upright journal-pins n?, that revolubly support the duplex-grooved rollers a near to the vertical sides of the bracesn, as shown in Figs. l and 2.

On the end bar t of the gate A at a proper distance from the lower rail a of said gate a latch-bar ois pivoted, so that one end, whereon a latch-hook o is formed, will project from the side of the upright end bar to have a hooked engagement with a vertical guardpost C, which is located at a proper distance from the post B on the opposite side of the roadway which is to be guarded by the gate A and in alignment with thelatter, the hooked engagement of the latch-bar being enforced by a spring o2. On the pulley L, that is secured on the forwardly-located shaft t', which rofates in perforations in the standards f, a rope or similar fiexible connection p is secured by one end p', and the other end portion p2 eX- tends -toward the upright gate-bar b, passes through a staple or ring-eye p3, and thence down to the latch-bar o', to which the terminal end is secured. The length of the rope p is so proportioned to the distance between the main post B and the guard-post C that the latch-bar o will be permitted to engage with the latter-named post when the gate A is closed and the end Q9 of the rope p is secured tothe pulley 7c, as before mentioned. On the other iianged pulley 7,1, that is supported by the shaft t" on the standards f adjacent to the main post B', a rope q is attached by one end q', the other end of said rope being secured to the rear-terminal end q2 of the gate A, as shown in Fig. The length of the ropes p and q is equal, and for the proper operation of the gate A the rope q should be closely coiled on the iianged pulley k when the gate A is closed and the rope p extended, as shown in Figs. l andi.

To afford means for a manipulation of the gate Afrom a vehicle approaching either side of the gate, so as to open and close it without alighting from the conveyance, there are two posts D, erected at equal distances from and opposite to the main post B, that is near the roadway. On each of .the posts D a pair of revoluble rollers r is pivotally secured to revolve near its upper end, said rollers being preferably grooved peripherally to adapt them to receive the cords s. On each side of the smaller pulleys m, that are affixed upon theshaft 'L'. one end of one of the cords s is secured, which cords have equal length and are partly wrapped upon the pulleys m, to which they are connected, and thence extendedto engagethe upper groove of each of the double-grooved rollers n3, and thence outwardly to rest upon the grooved periphery of one of the rollers o' on each post D, their outer terminal ends being secured to a weight t, which is adapted to serve as a handle, as shown in Fig. l.

Then the gate A is closed, the cords s will be closely wrapped upon the pulleys m and the weights t elevated.

Upon the pulleys m, which are secured upon the transverse shaft t" near the rear end of the gate A when t-helatter is closed, a pair of cords u are attached by one end of each cord to its respective pulley. Said cords are forwardly extended and passed around t-he lower grooves of the doubled-grooved rollers n3, and thence toward the posts D, resting in the grooves of the disengaged rollers r on said posts, the unwrapped cords u having such a relative length as will permit their attached weights c to hang near the base of the posts.

In use, if the gate A is closed, as shown in Fig. 1, the party in a vehicle who desires to open the gate grasps the elevated weight t, which is on the post located on the side of the gate approached, and by a downward draft on said weight unwraps the cord s and wraps the rope p upon the pulley 7c, which will lift the latch-bar o, so as to disengage it, and then move the gate Atoward the post B until said gate is completely withdrawn from its positionacross the roadway. Vhen the rope p is wrapped upon the pulley 7.9, the rope q will be uncoiled from the other pulley 7e, the cords u wrapped upon the pulleys on', and the weights o elevated. After the gate has been passed by the vehicle and its occupants the weight t', that has been elevated, must be depressed, when the gate Will be closed and all the parts restored to the position shown in Figs. 1 and 2.

Persons walking may pass the gate A by simply lifting the latch 0 and shoving the gate endwise.

To facilitate the movement of the gate A in either direction of itsy travel there are small rotary rollers w secured to engage with the sides of the lower rail a of the gate, said rollers being mounted in bracket-frames, which are secured to the inner faces of the upright studs f to permit the rollers to loosely and oppositely bear upon the gate-rail` as shown.

Over the gate-supporting frames and the rigging mounted on them a roof E is fixed by its engagement with the upper ends of the standards f f', which will protect the ropes and pulleys from obstructions, such as snow or sleet, that would prevent their free action if they were exposed to the same.

Itis claimed for this gate that it is light, strong, inexpensive, and convenient, not liable to be obstructed in operation, and readily adaptedto any situation where a movable gate is needed.

Having thus described my invention, I claim as new and desire to secure by Letters LPaten tl. The combination, with a gate having two main'posts, a frame on each post, gate-supporting rollers on said frames, and a guardpost toward which the gate may slide, of a pulley revolubly mounted in each gate-supporting frame, two ropes secured atone end of cach to the gate and at their other ends tov the respective pulleys, and a'riggingof cords IIO IZO

adapted to revolve Athe pulleys and draw either end ol the gate to open or close it,suh stan tially as set forth.

2. The combination, with agate having two main posts, a frame on each post, gate-supporting rollers on said frames, and guides on the gate engaging said rollers, of a guardpost removed from the main posts and toward which the gate may slide, a spring-actuated latch-bar on the gate adapted `to hook fast to the guard-post, a flanged pulley revolubly mounted on each gate-supporting frame, a rope on each pulley secured thereto and to the ends of the gate, and a rigging of Cords secured to the revoluhle supports of the flanged pulleys and adapted to revolve said pulleys and open or close the gate from either side, substantially as set forth.

3. The combination, with a gate having guides on its rails and two main posts, gate supporting frames on the sides of the main posts, grooved rollers on thelraines engaging said guides, a latch-bar on the outer end ot' the gate, and a guard-post toward which the gate may slide and be latohed thereto, of two flanged pulleys secured on transverse shafts revolubly supported on the gate-supporting trames, a rope attached by one end to one FRANK WILLIAMS.
