FARM-GATE Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed .Tune 22, 1908. Serial No. 439,808.

To all whom it may concern:

Be it known that we, GEORGE lV. GwYN, HARRY L. Ross, and HAMAN R. ROBBINS, citizens of the United States, residing at Smyrna, in the county of Rutherford and State of Tennessee, have invented certain new and useful Improvements in Farm- Gates, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in farm gates, and more particularly to opening devices therefor.

The object of the invention is to provide a simple and practical gate of this character which will swing in either direction and always away from the operator, and which may be conveniently and easily opened'and closed at points at any desired distance from the gate.

Titti the above and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed and illustrated in the accompanying drawings, in which Figure 1 is a perspective View of the improved gate; Fig. 2 is a side elevation of the same; Fig. 3 is a horizontal section taken on the plane indicated by the line 3 3 in Fig. 2; Fig. 4 is a detail view of a portion of the hinge end of the gate and the bracket arms thereon, and Fig. 5 is a side view of the bracket arms.

ln the drawings 1 denotes the hinge post, 2 the latch post, and 3 the improved gate, here shown as consisting of a plurality of spaced horizontal bars united by upright bars and diagonal braces, as shown more clearly in Fig. 2.

The upper pivot of the gate comprises a hinge member 4 having` a forked end engaged with and bolted upon the post 1 and a bearing eye at. its other end to receive the upwardly projecting pivot stud 6 of a coacting hinge member 7, which latter' has a forked lower end straddling the upper edge of the gate and bolted thereto. Said member 7 is also provided with a projecting arm l which engages the upper horizontal bar of the gate and is bolted thereto.

The pivot or hinge at the lower end of the gate comprises a member S fastened to the gate and provided with a pivot 9 and a laterally projecting arm 10; and it also comprises a bearing member or block 11 having a socket 12 to receive the pivot 9 and cam portions or projections 13 which are engaged by the arm 10. The pivots 9, 6 are adapted to have a slight vertical movement in addition to their rotary movement so that as the gate is swung it may move over the cam portions or projections 13, which latter are so arranged that they tend to maintain the gate in either its closed or its open positions.

Secured to the inner face of the latch post 2 is an angular keeper plate 1li to receive a spring latch 15 carried by the free end of the gate. Said keeper plate has a vertical iiange 16 secured to the post and a horizontal flange formed wit-h a central notch 17 and oppositely inclined or curved ends 1S which are engaged by the latch 15 and serve to direct the latter into the notch 17. Said latch 15 is preferably in the form of a resilient metal plate or rod secured at its lower end at 19 upon the free end of the gate and having a vertical portion to co-act with the keeper 14 and a horizontal portion 20 formed by bending the upper end of the rod upon itself, as shown..

The latch and gate are adapted to be operated from distant points by drawing downwardly upon cords or other handles 21 depending from levers 22 fulcrumed intermediate their ends upon posts 23 located on opposite sides of the gate along the roadway and at suitable distances from the gate and connected to the latter by cables, wire ropes or other iiexible elements 24C, 25. The latter have their inner ends connected to the gate and latch, as presently explained, and their outer ends after passing around guide pulleys 26 mounted in brackets 27 on the posts 23 are connected to the inner ends of the levers 22, as clearly shown in Fig. 1. lt will be seen that by employing` the cables 24, 25 l and connecting them to the levers 22 as set forth comparatively short operating levers may be employed and they maybe located at any distance from the gate.

Mounted upon the hinged or inner end of the gate 3 are two horizontally disposed bracket arms 28, 29 which project rearwardly and outwardly from said pivoted or hinged end of the gate and are disposed at an angle with respect to each other, as shown more clearly in Fig. 3. These arms 28, 29 serve as levers for actuating the gate and they are provided with guide devices for the operating cables 24, 25. Each of the arms or levers 28, 29 ispreferably formed from a metal strap and has a straight inner end 30 bolted to one side of the gate and an angularly extending outer end which is bent upon itself to form a loop 31 in which is journaled, upon a pivot 32, a grooved pulley 33. Said angular outer portions or loops of the arms 28, 29 are connected together by a brace bar 34 which is secured by bolts 35 and the latter also secure to said arms metal straps 36 which are bent to form supports for grooved pulleys 37, which latter are journaled upon the extended ends of the pivots 32. The outer extremities of the straps 37 are bent or curved, as shown at 38, to provide guide arms and to form a flared mouth or entrance for the space in the arm between the strap 36 and the loop 31 and in which the pulley 37 is ar-l ranged. The strap 36 upon the arm 28 is preferably arranged upon the top of the latter while the other strap is arranged upon the bottom of the other arm 29 in order that the inner ends of the cables will be held out of contact with each other. The cable 24 extending from one side of the gate passes over the pulley 37 on the arm or lever 28 at the adjacent side of the gate, then through the loop 31 and the pulley 33 on the other arm or lever 29 at the opposite side of the gate, and is connected to a link or rod The other cable 25 passes over the pulley 37 on the inner ,arm or lever 29 and then through the loop 31 and the pulley 33 on the other arm or lever 28 on the far side and is similarly connected to a link 40. The links 39, 40 have their opposite ends connected to a tension or adjusting device 41 here shown in the form of a turn buckle attached to one end of a wire or similar connection 42 which has its other end connected to the horizontal arm 20 of the latch 15. The device 41 permits the latch to be adjusted so that when either of the cables 20 are drawn upon their initial movement will disengage the latch from its keeper and their continued movement will cause the gate to swing on its pivot or hinge in either direction according to which of the two cables is operated.

In operation, assuming the gate to be in its closed position, when it is desired to open the gate, one of the hand cords 21 is pulled downwardly so that the lever attached to it will draw upon one of the operating cables and the latter will swing the gate away from the operator and to an open position in which it will be retained by oneof the cam portions or projections 13 upon the pivot bearing 11. lhen one of the operating cables is thus actuated the latch will be first released and the gate will then swing upon its pivot or hinge owing to the pull exerted by the cable on one of the bracket arms or levers 28, 29.

From the foregoing it will be seen that the gate is exceedingly simple in construction so that it may be produced at a small cost and will be strong and durable. It will be further noted that it will always open away from the operator and that it will be effectively retained in both its open and closed positions and when locked cannot be opened by live stock.

While the preferred embodimentjof the invention is shown and described in' detail it will be understood that the invention is not limited to the specific construction set forth and that various changes in the form, proportion and minor details may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. Y

Having thus described the invention what is claimed is :1 Y

l. The combination of a horizontally swinging gate hinged at one end, angularly projecting lever arms at the hinged end of the gate, the outer ends of said lever arms being provided with loops and with spaced straps having angular deflecting ends, guide pulleys journaled in said loops and between the latter and said straps, a latch for the gate, and operating cables extending in opposite directions and connected to said latch, cach of said cables beingpassed through the loop of one lever arm and around the pulley in such loop and over the other pulley in the opposite lever arm.

2. The combination of a horizontally swinging gate hinged at one end, angularly projecting lever arms at the y'hinged end of the gate, the outer ends of said lever arms being provided with loops and with spaced straps having angular delecting ends, guide pulleys journaled in said loops and between the latter and said straps, a latch for the gate, operating cables extending from opposite directions and each passed through the loop on one lever arm and around the pulley in such loop and also over the other pulley in the opposite lever arm and a tension device between the latch and the inner ends of said cables.

3. The combination of a horizontally of said Cables being passed through the loop of one lever arm and around the pulley in such loop and over the other pulley in the opposite lever arm, and levers pivoted intermediate their ends at distant points on opposite sides of the gate and. having said operating Cables connected to them at one end.

In testimony whereof We hereunto affix our signatures in the presence of tWo Wit nesses.
