GATE.

SPECIFICATION forming part of Letters Patent No. 762,057, dated June '7, 1904. Application filed July 16, 1903. Serial No. 165,784. (No model.)

To all whom, it may concern:v

Be it known thatl, TERELIUS A. HILL, a citizen of the United States, residing at Maryville, in the county of Blount and State of Tennessee, have invented a new and useful Improvcment in Gates, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to gates which extend across a roadway or entrance to a building or other similar passage. The invention has reference particularly to gates which are supported at one end upon a hinge adapting the gate to move vertically upon said hinge.

The object of the improvement is to provide a simple and eflicient gate embodying devices adapting the gate to be turned upon its hinge by pulling a cord or similar device extending perpendicular, or substantially so, to the plane of the gate.

The improvement includes means for automatically latching the gate in the closed position and in the open position, improved means for turning the gate, and other features, which will be hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of a gate embodying my improvement. Fig. 2 is a plan of the same gate. Fig. 3 is a side elevation of the hinge end of the gate. Fig. 4 is a plan of the mechanism shown in Fig. 3. Figs. 5, 6, and 7 are detail views illustrating the construction of the gateframe.

Referring to said drawings, 1 is the gate proper. This is shown composed of the top rail 2, bottom rail 3, front upright 4, rear 1 upright 5, counterbalance-chest 6, and braces 7 8 9. Said gate is hinged on the horizontal shaft 10, which shaft is supported by the posts 1111, said posts being located at opposite sides of the gate and substantially oppo site each other, the ends of said shaft being suitably secured to said posts and said shaft passing through arms 12 on said counterbalance-chest. The forward ends of the braces 7 are shown secured to the upper rear corner of the gate-frame, and the rear ends of said braces are secured to the upper forward corner of the counterbalance-chest. The braces 8 are shown secured by their forward ends to the lower rear corner of the gate-frame and by their rear ends to the middle of the forward portion ofsaid chest. The braces 9 are shown attached by their forward ends to the lower front portion of said chest. Said braces constitute a strong and rigid connection between the gate-frame an d the counterbalancechest, and they are preferably detachably secured to the gate and the counterbalancechest to the end that the structure may be readily separated and the parts crated for shipment in knockdown form and in order that my improvement may be readily and economicall y applied to ordinary hinged gates already constructed.

Between each arm 12 and the adjacent post 11 a guy-wire 13 is attached to the hingeshaft 10 and extends thence horizontally and obliquely forward to a suitable connection with the gate. The drawings show a V-shaped brace-wire 14, extending from the upper and forward corners of thegate-frame rearward to about the middle of the gate-frame and joined at such point to said guy-wires 13. Said guywires are shown secured to said hinge-shaft by means of hook-bolts 15, extending horizontally through said shaft.

A stop-bar 16 is secured horizontally to the posts 11 11 a short distance above said hingeshaft and far enough forward to engage said guy-wires 13 when the gate has assumed the upright position. Since said guy-wires are under tension and have some resiliency, they constitute an elastic buffer for the stopping of the upward movement of the gate.

A locking-bar 17 is hinged by its lower end between the forward portions of the braces 9 by means of a pin or bolt 9*, extending horizontally through said braces and said bar and guided by its upper end between the forward portions of the braces 7. A latch-wire 18 extends from the upper end of said locking-bar forward along the gate-frame to latch mechanism to be hereinafter described. Said latchwire is under tension and tends to hold the upper end of said locking-bar normally at its forward limit. The relative dimensions and locations of the parts are such as to bring said locking-bar 17 horizontally across the upper edge of said stop-bar 16 and permit it to rest in a notch 19 in said stop-bar when the gate has been turned into the upright position. Said locking-bar has a notch 20 in its edge which is opposite the gate-shifting spring to be hereinafter described, and said notch is so located as that when the gate is in the upright position the portion of the stop-bar at one side of the notch 19 will extend into said notch 20 and hold the latter against movement upon its hinge in either direction. The notch 19 in the bar 16 is wide enough to permit the lateral movement of the locking-bar 17 sufliciently to disengage the latter bar and the bar 16 from each other. The bolt 9 extends through the bar 17 at such an angle as to cause the upper end of said bar to bear against the brace 7, which is at the side of the gate corresponding to the location of the notch 20 in said bar, and the flexibility of the braces 9 permits the upper end of said bar 17 to move away from said brace 7. The upper end of said bar 17 is narrow enough to permit said bar to be drawn toward the opposite brace 7 far enough to permit the disengagement of the bars 16 and 17. Obviously this means of intlerlocking the bars 16 and 17 may be modifiec.

By means of a spring 21, suitably attached to the upper end of the locking-bar 17 at the side of the latter opposite the notch 20 in said bar, the gate is shifted from the closed to the open position, and vice versa, and the drawing of said spring moves the upper end of said bar rearward away from the gate-frame,

whereby the latch wire or cord 18 is drawn and the latch actuated preliminary to the raising of the gate, and as the action of said spring is lateral to the plane of the gate as well as rearward the upper end of said locking-bar is also drawn away from the plane of the gate in the direction opposite the notch 20. Thus when the gate is open and the locking-bar is in engagement with the stop-bar the drawing on said spring for the closing of the gate will, as a preliminary step, draw said locking-bar laterally until the notch 20 is out of range of the adjacent upright portion of the bar 16.

The spring 21 is actuated by means of a vertical shaft 22, secured in suitable bracketbearings 25 and 25 and having at its upper end the lateral extension or arm 23. As already stated, one end of said spring is attached to the locking-bar 17. The other end of said spring is suitably attached to the outer end of the arm 23 of said shaft 22. The drawings show this connection made by means of a swivel-post 24, secured to said arm. \Vhen the gate is closed, the arm 23 stands in approximately the position shown in Fig. 4, forward of the vertical plane in which the gatehinge lies. When the gate is to be raised, the shaft 22 is rotated a half-turn, so as to swing said arm outward away from the plane of the gate, as indicated by the dotted half-circle in Fig. 4. In this position the direction of the action of the spring will be rearward across the plane of the gate. As already stated, the

rearward drawing of the spring will draw said locking-bar 17 rearward sufficiently to draw the latch wire or cord and release the latch mechanism at the front or free end of the gate. The continued drawing of said spring will then rotate the gate upon its hinge until the upright position is nearly attained. Then momentum will continue the movement of the gate until the guy-wires 13 bear against the stop-bar 16 and said stop-bar and the lockingbar 17 have interlocked.

hen the gate is to be closed, the shaft 22 is rotated a half-turn in the reverse direction, whereby the arm 23 is returned to its original position. This causes said spring to draw forward across the plane in which the hinge of the gate lies. As already stated, the action of the spring when in this position draws the locking-bar laterally and disengages said bar from the stop-bar. Then the continued action of said spring turns the gate forward upon its hinge until the latterv is nearly in the horizontal position.' Then momentum continues the movement of the gate until the horizontal position is attained and the latch mechanism is engaged.

Any suitable mechanism may be employed for actuating the shaft 22, and for the convenient engagement of said shaft the drawings showacross-head H applied to said shaft just above the bracket 25, and to said crosshead links 29 and wires 30 may be applied for turning said head.

The top rail 2, bottom rail 3, front upright 4, and rear upright 5 are preferably distinct pieces joined at the corners of the gate by elbow clamping-plates 43. Said plates are concave on their inner faces corresponding to the exterior of said rails and uprights, and two such plates are placed at each corner and bound to the adjacent rail and upright by bolts 44, extending transversely through said plates and the rail or upright which is in line with said bolt. The top rail and the bottom rail each extend forward beyond the front upright into the space between the two posts 45, by which the free end of the gate is held against lateral movement. At 47 an elbow-lever 46 is hinged by one of its arms to the front upright 4, so as to adapt said lever to move in the plane of the gate. From said hinge said lever extends forward and then upward almost to the top rail. At 48 the latch-wire 18 is joined to said lever and extends thence rearward be tween the upper elbow-plates 43 to the upper end of the locking-bar. To provide space for the passage of said wire between said plates, the latter may be provided with. notches 49 opposite the line traversed by the wire. A middle upright 50 is shown secured by clamping-plates 51, applied to each side of the end of said upright and the side of the adjacent rail and secured by bolts 52.

Said plates 51 may be provided with notches 53 to make room for the latch-wire 18. Ob-

viously the notches 49-and 53 may be omitted wire extends downward to the latch 55, which latter engages the horizontal latch-bar 56.

Drawing the latch-wire 18 toward the inner or hinge end of the gate will raise the free portion of the horizontal arm of the elbowlever 46, and the latter will lift the vertical latch-wire 54, whereby the latch 55 is lifted out of engagement with the latch-bar 56.

An antifriction-roller 57 loosely surrounds the free end of the top rail 2 between the posts 45, and asimilar roller 58 similarly surrounds the free end of the bottom rail. Said rollers tend to reduce friction between the gate and the posts 45.
