STEPHEN A. DUGLAS BOZELL, OF ATLANTA, INDIANA.

GATE.

SPECIFICATION forming part of Letters Patent No. 403,911, dated May 28, 1889.

Application filed March 13, 1889. Serial No. 303,075. (No model.)

To (LZZ whom it may concern.-

Be it known that I, STEPHEN A. DUGLAS B0zELL,a citizen of the United States, residing at Atlanta, in the county of Hamilton and State of Indiana, have invented certain new and useful Improvements in Gates, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in gates; and it consists in the construction and arrangement of parts hereinafter described and claimed.

The object of my invention is to provide a gate which may be readily adjusted vertically, so as to increase or diminish the space between the bottom of the same and the ground.

A further object of my invention is to provide simple means for raising or lowering a swinging gate, and one which can be readily operated, strong and durable, and cheaply manufactured.

I attain these objects by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate corresponding parts in the several views, and in which- Figure 1 is a side elevation of my gate. Figs. 2, 3, and 4 are detail views of the lower hinge and bearing and their respective members. Fig. 5 is a detail of a catch, and Fig. 6 is a detail of the guide.

In the drawings, A represents the supporting-post, and B the opposite or fastening post.

To the postA is secured a vertical bearing rod, 0, cylindrical in form and located a short distance from the post. It is held rigidly in place and supported by tie-rods c, which are firmly clasped to the same and extend back through the post.

D represents the gate, by preference composed of a rectangular frame, with pickets secured thereon. The inner end bar, d, of the frame extends up beyond the top of the same and has strap-hinges E and E secured thereto, which are formed with cylindrical openings, through which passes the rod C, the

lower hinge having a flaring lower end with a fiat under face, as shown.

To give stability to the gate and to assist in holding it in a proper horizontal position,

a metallic braee-rod, F,is attached to a hook, f, on the bottom of the front of the gate, and extends up the front and obliquely back above the top through the upper end of the bar (1, its inner end having a yoke formed thereon, which has a grooved pulley, f, journaled therein resting against the back of the supporting-rod C. The brace F is separated near its forward end, and has a tightening-screw thereon for connecting the ends.

The latch G is constructed with a vertical connecting-bar, g, and two pivoted latch-bars, 9 which work in guides g and extend beyond the gate. The top of the bar 9 has a ring thereon, to which is attached the end of a wire or cord, 9 passing up over a pulley on the gate, its opposite end being secured to the bar (1. A hand-piece, 9 is attached to the rear end of the Wire, so that the same maybe drawn out to raise the latch. The catches b are secured at intervals on the post B to correspond to the vertical adjustment of the gate. They are constructed to permit the gate to be operated in either direction.

To raise the gate to permit sheep or small stock to pass under and thereby have access to the pastures, I secure a lever, H, to the side of the end bar, (1, by forming an elongated slot in its end, through which passes a fulcrum arm or support, 71, which is rigidly secured to the gate. The long arm of this lever is extended back toward the center of the gate, and is supported, to hold it in a horizontal position, by a support or bracket, h fastened to the gate. The short arm of the lever has a hook, 7L3, thereon, which projects beyond the end, and is adapted to engage with teeth on a rack-bar, I, secured on the post A. By this construction and arrangement it will be seen that the lever can be forced into engagement with the rack-bar and that by raising the long arm the gate is raised. To retain the gate in this position and yet permit it to swing freely, I place on the rod 0, below hinge E, an inverted conical-shaped bearing, K, which moves freely on the rod. The under face of the hinge E rests and moves on the corresponding face of the bearing. To this bearing is pivotally attached, in a manner which permits only a vertical swinging movement, a pawl, k, having two arms on its sides and a pointed outer end, the latter being adapted to engage with the teeth of a rack-bar, L, rigidly secured on post A. Projecting out from the'upper side of the bearing K is an arm, 10 which extends back and enters guide M, which is secured to the post, (or a vertical groove maybe formed in the rack-bar, which it may enter,) the purpose being to prevent the bearing from moving laterally. To raise the bearing with the gate, a yoke, O, is secured to the gate or hinge E, which loosely clasps the reduced end of the bearing K. When raising the gate, the operator places his foot against one of the arms on the pawl and forces it into the rackbar at the required moment. The bearing is thus prevented from moving down the rod 0. v

I am aware that many minor changes in the construction and arrangement of the parts of my improvement can be made and substituted for those shown and described with out in the least departing from the nature and principle of my invention.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a post having a rod thereon, of a gate hinged on the rod and adapted to move vertically thereon, a rackbar on the post, and a lever on the gate adapted to engage with said rack-bar, substantially as described.

2. The combination, with the post A, of the rod G, the gate hinged to the rod, a bearing below the hinges having a pawl pivoted thereon, arack-bar on the post, a lever on the gate, and a rack-bar opposite said lever on the post, substantially as described.

3. The combination, with the post A and cylindrical rod 0, of the gate movably supported on the rod, the vertically moving bearing K on the rod, having a pawl pivoted thereon and an arm extending therefrom, the rack-bar L on the post, the yoke O on the gate clasping the bearing, and alever on the gate for raising the same, substantially as described. 4

4:. The combination, with the post A and the cylindrical rod G, of the gate hinged on the rod and adapted to be moved vertically, the lever H on the gate having an elongated slot therein, the rack-bar I on the post opposite the lever, the bearing K below the hinges having a pawl and arm thereon, the rack-bar L' opposite the bearing, a guidein which the arm works, the yoke 0 on the gate clasping the bearing, and the latch on the front of the gate having a. flexible connection with the rear, substantially as described.

5. The combination, with the rod 0, of the gate hinged thereon, and a brace-rod, as F, extending from the bottom of the front of the gate to the upper end of the rod 0, substantially as described.

6. The combination, with the post having a rod thereon, of a gate supported on the rod, a movable bearing on the rod below the gatesupporting hinges, a rack-bar on the post, and a pawl on the bearing engaging said rackbar, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
