GATE.

SPECIFICATION forming part of Letters Patent No. 746,777, dated December 1 19 Application filed May 8, 1903. Serial No. 156,138. (No model.) I

mount; also, to automatically hold and re-.

lease the gate in its open or closed position, and, further, to provide against the sagging to which usage subjects the gate. These objects are preferably attained by a movable gate-carrier, which is operated by a series of,

levers, so that it may tilt in opposite directions in a plane parallel to the disposition of the fence, whereby a gate carried therebymayalso be tilted in one direction or another, and thus sway open or close at will. In tilting the gate also is released from the catches.

holding it.

Illustrating this invention, reference is had to the accompanying drawings, in which- Figure 1 is a perspective view of the gate structure embodying myimprovements; Fig. 2, the top plan view of a portion of the tilting mechanism. Fig. 3 illustrates a vertical section of the tilting mechanism. Fig. 4illustrates in elevation a portionof the gate carried by the tilting carrier, and Fig. 5 is an elevational view in section showing a gateadjusting means.

Similar characters of reference indicate like parts throughout the figures.

To a post 1 of a stretch of fence. 2 may be pivoted by means of a stud 3 a twin power point member or forked lever 4, provided with arms or power-points 5 and 6, and to the outer end 7 of this lever is pivoted a frame 8, having arms 9 and 10, to which is suitably hinged, preferably by studs 11 and 12, the stile 13 of a gate 14. The lower portion of the frame 8 is provided with a lug 15, which is pivoted to a lug 16, attached to the lower portion of the post 1.

Pivoted, preferably, to the tops of posts 17 and 18, respectively, and on the opposite sides of the gate 14 and on the same side of the fence to which the gate is hinged are levers 19 and 20, respectively, either serving to open or closethe gate 14, according to the direction in which the gate is swung. To each of these levers 19 and 20, respectively, are connected a plurality of cables, one of which, 21, being connected to the outer end 22 of the lever 19, and passing through a retainer 23 is connected to the inner or handle end 24 of the opposite lever 20. To the outer end 25 of said lever 20 is secured acable 26, the opposite end of which is fastened to the arm 6 of the lever 4, and a cable 27 is secured to the outer end of the arm -5 of the lever 4 and is carried to and fastened to the inner or handle end 28 of the lever 19, said cable 27 being retained in place, as at 29.

As is obvious, when pressure is applied to the lever 19 in'the direction of the gate 14 a draft will be imparted to the arm 6 of the member 4 through cables 21 and 26,.respectively, through the instrumentality of the lever 20, which will cause the outer end 7 of the member 4 to travel laterally, as seen in Fig. 2, whereby to tilt the frame 8 carrying the gate 14, causing the latter to be released from suitable holdings at the post 30 and sway toward the post 31, which is provided with a catch 32 to retain the gate. As is further obvious, to again close the gate the lever 20 is manipulated, which will transfer the draft to lever 5 of the member 4 through the instrutnentality of the cables 21 and 27 and the lever 19, which will cause the frame 8, pivoted to the member 4, to tilt in the opposite direction to that first named, whereby to release the gate from its holdings 32 and cause it to sway into suitable holdings at the post 30.

As a means of adjustment whereby the gate when sagging at its free end may be raised I provide the arm 9 of the tiltable carrier 8 with an elongated slot 33 and an adjustingnut 34, against the inner extremity ofwhich, as at 35, the stud 11 of the gate 14 bears, and as is obvious by this means the free end of the gate may be adjusted up or down at will. Thus it will be seen that in approaching with a vehicle a driver may manipulate the lever 19 and open the gate '14 without dismounting from his seat, and after passing through by manipulating the lever 20 may in like manner close said gate. It will be further noted that by tilting the gate in one direction or another to cause it to sway to and fro, through the instrumentality of a tilting member to which said gate is connected, the accidental disengagement of the gate from its bearings isimprobable. Furthermore, thetilting member, together with the operating mechanism for the same, may be manufactured independent of.the fence and gate structure, which is a desideratum. It is also to be noted that by carrying the gate by a tilting frame and connecting the tilting mechanism to the frame the liability of distorting the stile of thegate is lessened, hence rendering the gate structure more eflicient and durable. It will be further observed that the tilting of the gate causes a displacement of the center of gravity thereof, which causesthe gate to open and close.

Various modifications may be resorted to within the purview of this invention.

Having thus described my invention, I claiml. A gate construction comprising a plurality of posts, a frame pivoted to one post and tiltable at its upper end only, a gate pivoted to said frame, means operating to tilt the upper end of said frame whereby to open and close the gate, and means to adjust said gate in said frame.

2. A gate construction comprising a series of posts, a frame hinged to one of said posts and being adapted to tilt only at its upper end, a gate carried by said frame, levers connected to said frame and adapted to tilt the upper end thereof and thereby open and close the gate, and an adjustment carried by said frame to prevent the free end of the gate from dragging.

3. In a gate construction, the combination of a plurality of posts, a member carried by one post, a gate hinged therein, a lever connected to the upper portion of said member and having two power-points, a pair of levers mounted on opposite sides of the first-named lever, a series of cables'connecting all of said levers, whereby when the extreme levers are operated, the gate-carrying member will be tilted only at its upper end in opposite directions whereby to open and close the gate, and means carried by said member for adjusting the gate so as to prevent it from dragging.
