GATE.

SPECIFICATION forming part of Letters Patent No. 515,430, dated February 2'7, 1894.

Applicationfiled July 25, 1893.

To all whom it may concern.-

Be it known that I, WILLIAM G. HOOKER, a citizen of the United States, residing at Abingdon, in the county of Knox and State of Illinois, have invented a new and useful Gate, of which the following is a specification.

The invention relates to improvements in gates.

The object of the present invention is to improve the construction of gates, and to provide a simple and inexpensive swinging gate, which maybe readily opened and closed without leaving a vehicle or dismounting, and in which the mechanism for operating the gate at a distance will not interfere with the opening and closing of thegate by a person on foot.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is aperspective view of a gate constructed in accordance with this invention. Fig. 2 is a reverse plan view partly in section of the operating mechanism, showing the position of the parts when the gate is closed. Fig. 3 is a horizontal sectional view of the operating mechanism showing the position of the parts when the gate is open, before the semi-rotating actuating frame has returned to its normal position. Fig. 4 is a vertical sectional view of the operating mechanism. Fig. 5 is a detail sectional View showing the weighted pawl in engagement with the plate of therotating arm which is connected with the gate. Fig. 6 is a detail perspective View ot the semi-rotating actuating frame. Fig. 7 is a similar view of the plate of the rotating arm. Fig. 8 is a detail view of the pivoted bar showing the stop. Fig. 9 is a detail perspective view of the upper rear end of the gate, showing the brace.

Like numerals of reference indicate corresponding parts in all the figures of the draw ings.

1 designates a swinging gate hinged to a post 2 and connected between its ends by a rod3 with a revolving arm 4, which is pivotally mounted on a post or other support 5, and which is adapted at every half revolution to swing the gate between alatch post 6 and a supplemental latch post 7 to open and close satin No. 4.81,:48. on model.)

the gate. The support 5 is provided at its top with a vertical pivot 8; the inner end of the revolving arm 4. has a perforation receiving the pivot; and on the latter beneath the revolving arm 4. is mounted an actuating frame 9 with which are connected operating ropes 10. The operating ropes are adapted to actuate the frame 9 a half revolution,wl1ich opens or closes the gate, and it is returned to its normal position by a spiral spring 11 in order that after returning to such initial position it may be again moved ahalf revolution by the operating ropes to actuate the revolving arm 4 a half revolution to open or close the gate. One half of a revolution of the revolving arm 4 opens the gate, and the next half of the revolution closes it. The spiral spring 11 has'its lower end connected with the support by a stop 12, and its upper end is secured to the actuating frame 9, which carries a pivoted weighted pawl 13 for engaging diametrically oppositely disposed teeth 14. of the revolving arm 4:, whereby the latter is connected with and carried by the actuating frame. The teeth 14 of the revolving arm are located on opposite sides of the pivot S, and may be formed of any suitable means, but are preferably constructed by recessing and beveling the ends of a plate 15, which is secured to the lower face of the revolving arm, and which is provided with a pivot opening to receive the pivot S. The weight of the pawl 13 is arranged on the opposite side of the folcrum point or pivot point from the engaging head, and is adapted to hold the latter in engagement with the revolving arm 4; but when the spiral spring returns the actuating frame to its initial positionfthe weight of the pivoted pawl is engaged by the stop, and is lifted for holding the pawl out of engagement with the revolving arm 4, and for leaving the latter perfectly free to turn, whereby the gate may be opened or closed by a person on foot without actuating the operating mechanism for opening and closing the gate at a distance. The pawl is pivoted or fnlcrumed by means of trunnions or journals formed integral with it and arranged in bearing recesses of the actuating frame.

The actuating frame is provided at diametrically opposite points with lateral extensions 16 to each of which is connected a pair of pivoted bars :17 and 18, which are normally arranged at substantially right angles, but which, when an operating ropeis pulled, are

adapted to swing around and to straighten as actuatingframe,whereby by pullingonthe-op eratlngropetheactuating frame may be moved a half revolution. The pivotedbarsl 7 and 18 may straighten, but are held against moving toward each otherand forming lessthan aright angle, by steps 19 consistingrpreferably of a keeper having a shoulder arranged sto en gage I the inner side of the bar 18 atthe inncr'pivoted' end thereof. By thisconstruction, when an operatingrope is pulled, the actuating frame is moved ahalf revolution carrying with it, the revolving arm 4; and after the completion of a half revolution on releasing the operating rope, the spiral spring returns the actuating frame to its normal position.

ternatelycngagedby the pivoted pawl to cause the arm 4 to rotate in semrrevolutions. The inner end of therevolvingarm 4 is covered by a cap plate 20, which protects theopcrating mechanism, and which'is'preferably circular and concave-convex; The operating ropes extend a suitable distance-from opposite sides of the gate and are provided with handles whichdepend from hangers of u ,7 rights 21; and the hangers areprovided-with" 35,

I pulled; I The rod 3, which has one end con- I nected with the. revolving arm 4, has its other end connected with an upper arm of a rocln pulleys 22 to enable the rope to be readily shaft 23, which is journaled on a vertical bar 24 of the gate, and which has alower arm connected with alatch 25. The latch 25 is adapted toengage keepers of the latch and supplemental latchposts, and is approximately L- shaped, and is provided at the top with a coil to impart resiliency to it to enable it to automatically engage the keepers, and to hold the gate open and closed. By connecting the rod 3 with the rock-shaft the latch is withdrawn from engagement with the keepers as soon as the operating ropes are pulled. The bar 24 of the gate is extended vertically to bring the upper end of the rock-shaft in the same horizontal plane as the revolving arm 4.

The gate is provided with a rearwardly and upwardly inclined "brace 26, consisting of strands of wire, and having its lower end secured to the bottom of the gate at about the middle thereof. The upper end of the wire brace passes through an inclined perforation 27 at the top of the gate at the inner end thereof, and is provided with a ring 28 and a washer 29; the ring is adapted to be turned to twist the wire to counteract any sagging; and the washer forms a bearing for the ring.

The actuating frame preferably consists of a circular plate or casting, and the lateral extensions 16 are preferably formed by bars so- I persons on foot.

Changes in the form, proportion", and the minor details of construction may be resorted to-without, departing from the principle ;orsacrificing any of the 'vention, By this means the endsof the plate 15 are al-' whole maybe a single casting. I The bearing recess for the pawl l3'is made in the upper face of an outwardlyprojeoting portionor lug 30; and two of these lugs or proj cot-ions 30 are providedand are arranged on opposite sides of 'one of the lateral extensions 16 to enable the mechanism to be applied without change toa gate swinging in'onedirection or the other. Tothis end the plate l5is'provided at'each end with opposite teeth 14 formed by bevelin g a longitudinalextension at each side.

It will be seen that the gate is simple and comparatively inexpensive in construction anism is positive and'reliablaandthat it does not intcrferewith advantages of this in- What I claim is I support,a horizon tally disposed revolving arm opening by hand by cured to thecircular plate or casting; butthe I and easily operated, that the operating mechmounted on the support and connected with s the gate, and capable of openingand closing the same, and asemierotati-n g actuating frame mounted on the'support andprovided witlra pawl detachably engagingthe arm, substantially as described; i
