GATE.

SPEGIFIGATION forming part of Letters Patent No. 471,851, dated March 29, 1892. Application filed November 27, 1891. Serial No. 413,300. (No model.) 7

To all whom it may concern:

Be it known that I, JOSEPH ELCOCK, a citizen of the United States, residing at Mechanicsburg, in the county ,of Cumberland and State of Pennsylvania, have invented new and useful Improvements in Gates, of which the following is a specification.

This invention relates to improvements in that class of gates that arearranged to slide on and between rollers that are supported by the gate-posts; and it consists in the construction and combination of parts in a sliding gate, as hereinafter more fully described, and particularly pointed out in the claims.

In the annexed drawings, illustrating the invention,Figure 1 is a perspective of myimproved sliding gate, showing the same as it appears when open. Fig. 2 is a vertical crosssection through the line 2 2 of Fig. 1, showing the vertically-adjustable roller-bearing box I for raising and lowering the end of the gate to give it a proper set. Fig. 3 is a vertical cross-section through the line 3 3 of Fig. 1, showing more clearly the grooved chain-wheel or double pulley and its crank-shaft for act-uating the gate. Fig.4 is aview of a modified arrangement of devices for revolving the pulley-shaft. Fig. 5 is a detail view of aportion of the forward end of a gate, showing the gatestile extended upward and carrying a roller to run on a rail or cross-bar connecting the upwardly-extending ends of two gate-posts.

Referring to the drawings in detail,'the numeral 1 designates the gate proper, which is composed of the usual stiles and longitudinal bars that may be suitably braced in any convenient manner, as shown.

The numeral 2 designates the latch-post, which is provided with vertical flanges 3 on the side toward the adjacent end of the gate, thus forming a vertically-elongated recess 4, into which one of the gate-stiles enters when the gate is closed. At the foot of this recess 4 is an anti-friction roller 5, that facilitates engagement of the gate with the latch-post.

The main gate-post 6 is made double or composed of two standards having their inner faces provided with vertical guideways 7 for receiving a vertically-elongated and vertically-adjustable box 8, in the opposite ends of which are journaled the flanged guide-rollers 9, between which the gate 1 is mounted, and along which the upper and lower longitudinal bars of the gate are enabled to slide freely and easily in opening and closing the gate. On the top of the double post or twin standards 6 is secured a plate or cross-piece 10, having a central screw-threaded aperture for passage of a screw-threaded crank-shaft 11, that is loosely connected with the upper end of the vertically-ad j ustable box 8, 1n which the rollers 9 are mounted. By turning the screw-shaft 11 in the proper direction the rollers 9 can thus be raised or lowered, as required, for the purpose of impartingthe desired set to the gate, so as to enable 1t to be operated with ease. I

At one side of the gate 1,between the latchpost 2 and main post 6, is arranged an lntermediate post 12, to which is secured a bracket 18, in the upper and lower ends of which are journaled flanged guide-rollers 14 above and below the upper and lower longitudinal gatebars, respectively, to assist in supporting and guiding the gate. The post 12 and bracket 13 also support a rotary shaft 15, on WhlCll, between said post and bracket, is securely mounted a double-grooved wheel or pulley 16 for attachment of chains or ropes 17, that are extended to the opposite ends of the gate'and secured thereto in any suitable manner. The attachment of these ropes or chains 17 to the opposite ends of the gate maybe eifected either by means of screw-eyes 18 oreyebolts 19, as preferred, or by any other convement means. The grooved wheel or pulley 16 may be rotated by means of a crank-handle 21 on the pulley-shaft 15, as shown. in Fig. 3, or, as

shown in Fig. 4, the crank may be replaced by a double-grooved wheel 22, having attached thereto ropes 23,passed over pulleys 24 at the top of the post 12 and carrying welghts 25 at their free ends, so that by pulling down on one of said ropes it will be unwound from the wheel 22 while the other weighted rope 23 1s wound thereon. By means of these weighted ropes 23 and grooved wheel 22, or by means of the crank 21, as the case may be, the shaft 15 and double-grooved wheel 16 may be rotated in the desired direction to open or close the gate. When the gate is moved in elther direction, as above described, one of the chains 17 will be unwound from the grooved wheel 16 as the other chain is wound thereon by the turning of the wheel and its shaft.

As shown in Fig. 5, the gate-

posts

2 and 12 may be extended upward and connected by a rail or cross-bar 26 to support a roller 27 on the upward-extended end of the forward gatestile, thereby further facilitating the opening and closing of a heavy gate. The rail or crossbar 26 should be supported at a sufficient height to permit the passage of vehicles.

It will be seen that the described arrangement of the sliding gate and its operating mechanism is such as to enable the gate to be readily opened and closed without the exertion of any great amountof strength or power, owing to the smoothness with which it will move in its bearings or supports. When closed, the gate is firmly and staunchly supported, and when open it exposes almost the entire width of the roadway for the passage of vehicles.

What I claim as my invention is 1. The combination, with a latch-post 2, a main gate post 6, comprising two parallel standards having guideways at their inner sides, and an intermediate post 12, having upper and lower guide-rollers 14, of averticallysliding roller-box 8, engaged with the guideways of the standards and provided with upper and lower guide-rollers 9, a cap-plate 10, connecting the upper ends of the standards and having a screw-threaded orifice, and a rotating screw-shaft 11, engaging the threaded part of the cap-plate, provided with a crankhandle, and loosely connected with the upper end of the roller-box, substantially as described.

2. The combination, with a latch-post 2, a main gate post 6, comprising two parallel standards having guideways at their inner sides, a sliding gate 1, and an intermediate post 12, having upper and lower guide-rollers 14, and a rotating grooved wheel provided with a rope wound thereupon and connected with opposite ends of the gate, of averticallysliding roller-box S, engaged with the guideways on the main gate-post and provided with upper and lower guide-rollers 9, a cap-plate 10, secured to the main gate-post and having a screw-threaded orifice, and a rotating screwshaft 11, engaging thethreaded part of the cap-plate, provided with. a crank-handle, and loosely connected with the upper end of the roller-box, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand and affixed my seal in presence of two subscribing witnesses.
