IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 124,858, dated March 19, 1872.

Nature and Objects of the Invention. The invention relates to a gate, which may 'he openethby means of cords connecting a latch e and open the gate; and when the gate is open to depress the catch, holding it in such position, elevate the latch, and close the gate; the object of the invention being to providea gate which tcan be operated by pedestrians in the ordinary manner, or by persons in vehicles, or mounted, without disinountiug.

Description of the Acconwanying Drawing.

Figure 1 is a perspective View ofthe invention with a part of the* upper bar ot' the gate broken out. Fig. 2 is 'a pla-n view of the same, showing the position of the posts and the inanner of operating the main cord.

Genemt Description.

A in the accompanying drawing represents a post having a catch, et, properly placed to receive the extremity ot' the latch B, which is attached to the gate G, and, in the present instance, has a downward pressure. In the upper part ot' the pest E of frame of the gate C, through which the latch B passes, is pivoted the bell-crank D, the outer end of the lower arm of whichis connected with the latch B by means of a cord or wire, c, drawn to proper tension.

adjacent the top ofthe post E, is provided with a cord or wire, c, connecting it with the cord L. The hell-crank is also provided with an arm or lever, i, so placed that byy its being de pressed the front of the bell-crank is elevated, thus raising the latch B and allowing the gate to he opened in the ordinary manner. The post The upper part of the bell-crank D, 4

H of the gate-frame is hinged to the gate-post I so that the gate C, in swinging, may describe a semicircle. The upper part ofthe post His provided on each side with staples or eyes b b l to receive and sustain the cord L, which is of proper length, and passes entirely around the post H, and extends on opposite sides of the post to 4thegrooved rollers m on the posts M M. Thus the cord L passes lroin the post M Vto the staple b through it; thence to and through the staple b, and thence to the curved roller m on the post M. At a point opposite the post H and midway between the staples b b the cord L is secured to the cord or wire e. The posts M M are situated opposite each other at any proper and desired distance from the gate, and in a line with the post on which the gate is hung. They are provided on top with slots a, so cut as to he at right angles to the plane ofthe gate C when closed. In these slots n are placed the grooved rollers m, fixed upon axles o, which are journaled at each side ofthe slot, their extremities on the side toward the gate heingprovided with the cranks P. The posts or standards It are so placed that when ythe gate is thrown open the latch B can enter the cat-ch Z, which is pivoted to the post R, and has an upward pressure; and its rear proj ecting back ot the post It is provided with a cord, passing through a sta-ple, w, on the saine side ofthe post R, which cord is of proper length, and is provided with a rin g, fu, through which passes the cord L.

It is obvious that the helhcrank D may he dispensed with, and the post E provided with a roller-wheel properly grooved or provided with an aperture to prevent the cord L slipping oft the post E. In the event of such arrangementv the cords or wires c and e may be united.

An automatic latch will answer in the place of the latch B.

The posts R and their attachments may also be dispensed with, as the gate will remain open when so swung.

A pulley or circular piece of wood may he used instead ofthe upper part of the post H, since it is only necessary that the line of tension of the cord L shall not pass through the vertical axis of the post H.

Operation. When it is desired to open the gate C the approach is made sothat the crank P can be reached, which crank is turned either toward or from the gate, and the cord L secured to the roller m is thus drawn taut, and, acting upon the cord 0r wire e, depresses the rear of the bell-crank D, thus elevating its front arm and raising the latch B. At the same time the tension of the cord L, by its'passing around the post H, is directed toward the standard opposite that side of the gate G on which the crank is being operated, and, the latch B being raised, the gate G swings open until it comes in contact with the standard last aforesaid, when the latch B enters the catch, on the lpost Iiand the gate is held open. After the above operation, when it is desired to close the gate, the crank m on the opposite post is turned. The cord L, thus drawn taut, acts as aforesaid to close the gate and elevate the latch. At the same time as it becomes taut the cord m is drawn upward, thus elevating the rear and depressing the front of the catch Z, and so freeing the latch B and allowing the gate C to swing.

It is obvious that by continuing the revolutions of the cranks l? the gate, when latched upon one of the posts R. may be :made to perform asemicircular swing and latch itself upon the post R on the side opposite that on which the crank is being operated.
