GATE.

SPECIFICATION forming part of Letters Patent No. 560,776, ated May 26, 1896.

Application filed April 11, 1895- To all whom it may concern:

Be it known that I, JAMES H. CHRISTOPHER, of Morrisonville, in the county of Christian and State of Illinois, have invented certain new and useful Improvements in Gates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in gates; and the object of the same is to provide an improved opening and closing mechanism.

A further object is to provide the gate with an improved vertical adjustment.

A further object is to arrange the operating devices for opening and closing the gate and for controlling its vertical position, so that the same may be actuated without alighting from the vehicle.

A further object is to provide an improved latch and latch-operating mechanism.

Still a further object is toprovide an improved device for holding and twisting the gate-forming wire strands.

With these objects in view my invention consists in the novel features of construction hereinafter fully described and claimed, and illustrated in the accompanying drawings, in. which- Figure 1 is a perspective view of the gate when closed. Fig. .2 is a similar view taken from a difierent point of view with the gate ajar. Fig. 3 is an elevation of the verticallyadjustable gate-supporting derrick. Fig. at is a detail view of the wire-twisting head.

A designates the double gate-post, preferably supported upon the ground-surface by a block or other device and held from lateral displacement by braces A. A lower bearing-block B and upper bearing-block C move vertically in thevdouble post,the same being connected by rod C. The upper block is pro-. vided upon its outer end with the frictionrollers Z) and upon its inner end with the cross-pin b, which bears on the inner side of the post, while block 13 has the frictionrollers 0 upon its inner side and the cross-pin 0 bearing against the outer side of the post,

the said cross-pin being secured between the ends of an arm D, which latter is pivoted at its inner end to the upper surface of block 13, while at its outer end it is provided with the vertically-disposed sheaves D. The outer portion of the said pivoted arm is confined to block B by stapled. The gate-supporting mechanism is carried by blocks 13 and C, and the latter, besides forming bearings for the gate-support, secure to the same vertical adjustment through the medium of chain E, having its ends secured to the inner ends of levers E, fulcrumed between their ends to braces A and at their outer ends extending through guide-posts F, as shown. Said posts are provided with removable pins f, which are insertible through the post and lever, so as to hold the outer end of the latter in a raised position, while each post is also provided with a pivoted latch f for locking the lever down with its forward end in a raised position, as indicated in Fig. 2.

-For supporting the gate G, I pivot between bearing-blocks B and C the derrick-post II, provided with the extended cross-arm H, to which the gate G is pivotally secured between its ends, as indicated at G. Arms II are braced to post H by the twisted wire 72-. A bracket I, which is curved forward at its extremities, is secured horizontally to post II and provided with the pivoted cross-arms I, which latter at their free ends are connected by lines '5 to the ends of operating-levers J, loosely secured between their endsto postsF. Theopposite ends of said levers J are connected directly together by the line J. Arms :1 are connected between their ends to the free ends of the vertically-swinging arm K, as shown, and the said arm is connected be tween its ends byline K to latch L. Said latch is pivoted at its outer end to one of the derrick cross-arms II and at its free end is extended through a recess in post II and held normally in a depressed position by the coiled 9 5 I pivotally connect thereto at a point midway between the center and rear end of the gate the arm M, pivotally secured at its rear end on vertical bolt M, supported by post N directly back of main post A, as shown. By means of this arm connection it will be seen and understood that when the derrick is turned to one side the gate will have a pivotal movement on arms H thereof and will be caused to fold back flatly against the derrick. The gate is pivoted centrally on the derrick and is provided at each end with a notched catch 0, so that when the gate is closed, as in Fig. 1, one of the catches will be engaged by latch L, while when the gate is entirely open the other catch will be in engagement with the latch. By this arrangement one and the same latch serves to hold the gate both open and closed. The gate, when being operated, having a longitudinal as well as swin ging movement, is readily projected between strips T on the inner side of the outer gatepost T, so that when closed across the road the free or outer end of the gate is securely held from movement in either direction, the longitudinal retracting motion secured from the operatingmechanismjust described being necessary to remove it from between said strips. It will be understood that the operating-line when drawn upon for either opening or closing the gate exerts such a pullupon the pivoted cross-arms I as to raise pivoted arm K, thus lifting latch L through the medium of line K from engagement with the catch carried by the gate.

In order that the movement and operation of arm M may be entirely accurate, the same is so arranged as to move vertically with the gate when the latter is either raised or lowered, and for this reason the outer end of the arm is allowed a vertical movement on the bolt M, before mentioned. In order to support the outer end of the arm when the gate is in a raised position as well as to assist in the elevation of the end of said arm, the depending latch Q is provided, which is 0011- nected at its free end to the upwardly-extending weighted chain Q, which depends over roller R, while line B extends from the point of connection of said chain Q to the lower derrick bearing-block, so that when the gate and arm are raised the weighted chain Q will exert an upward pull upon latch Q, and cause it when raised to engage the later ally-extending bracket N 011 post N, while when the gate is lowered line B will draw the said latch inward and out of engagement from said bracket, and thus permit the outer end of arm M to descend along with the gate. An upwardly-extending inturned catch S is secured to the upper edge of the gate and adapted to engage arm M when the gate is closed for the purpose of bracing together the gate and arm, and thus making the structure more rigid and secure.

By means of the mechanisms and devices herein shown and described it will be seen and understood that the gate may be adj usted either upward or downward in a closed or open position or when partially opened. The

connections are such that the outer end of the long guiding-arm M has its movement controlled automatically.

The gate G is made up of an outline framework provided with a series of vertical and transverse wire strands U. Each strand is a doubled wire having one end secured to the gate-frame, while the opposite end surrounds the twisting-head V,havin g an axially-formed bearing at one end and a wrench hold at its outer projecting end. This twisting-head is slotted longitudinally on opposite sides, around which the wire is looped, so as to secure a firm hold for twisting.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a gate-post provided with a guideway, a gate-support movable vertically in said guideway, and the lovers extended in opposite directions and connected at their adjacent ends to the support so as to adjust the same, substantially as shown and described.
