earn-ornaa'rme, MECHANISM.

To all whom it may concern; a

Be it known thatwe, JAMES M. IMCDAN- EL and CLAUD MODANIEIJ, citizens of the United States, residing at Wellington, in the county of Collingsworth and State of Texas, have invented certain new and useful Improvements inGate-Operating Meohanisms and we do hereby declare the following to beat full, clear, and exact description of the invention, such as will enable ,others skilled in the art towhich it appertains tomake' and use the same. i i This invention relates to gateoperating opening and closing mechanism, particularly that typeadapted to be operated by the approach of a vehicle toward the gate so as to move the gate to open position, and to be again operatedby the vehicle after the same has passed through the gate opening so as to eflfectclosing of the gate, and an object of the invention is the provision of a more simple and durable operating mechanism that can beconveniently associated with any type of gate and will be more efficient in operation. a i e ,Other objects will-appear and be better understood from that embodiment of our invention of which the following is specification, reference being had to the accompanying drawings, forming a part thereof, in which: v s i a a Figure 1 is a perspective view,showing the operatingmechanism applied to a gate with'thegate in closed position,

said upper and lower panels begate by means of 'a pivot pin 2, and has its a a,

lower end depending a short distance below the lower panel of the gate, as shown in Fig. 1 of the drawings. A latch rod 3 hasfone endpivoted to the vertical link 1, at a point adjacent the upperend of the link 1 and the oppositefend of the latch rod 3 terminally extends beyond the panel andfthe free end of the gateB A keeper 4 is mounted on the inner surface of a latch post E, which post is arranged opposite the post 0, andgis provided with a central, recess, and the said keeper is carried a vertically disposed bar 5,"the upper end of the bar being pivoted to the post E, adjacent the upper end of the post, and thelower end ofthe bar 5 has connection with the upper end of a vertically disposed ,coil spring 6,.the lower end offthe spring being conneoted yto. the inner side of thepost E adjacent the, lower end, of the van post. When the gate is inclosed position, as

shown infFig; 1,the outer'or free end of the latch rod 3 :is received by the recess in the keeper 4:, so as to prevent accidental opening I of the gate. An elongatedbar is disposed formed of resilient material, and extends parallel with the gate and the inneryend of the bar? has connection with the lower end a of the linkmember 1, by means of agpin 8, The outer or rear end of the bar-7 has connection with the innernend of an 9,

which is disposed below the :fence and gate structure, and has itsouter end extended be:

tween the sidesof a V-shapedelelnent 1 0, and

below the lower panel ofrthe gate B and is connected to the apex portion of the V- shaped element. A pivot bolt 11 extends through the apex portion of the V- shaped element 10, so astoadmit of the iv-shaped elernent having horizontal oscillatory move: ment. ,A second V-shaped element, designated 12, is disposed above and in spaced relation to he first-mentioned \l-shapediele- Inent and has the apex portion pivotally connected withthebolt 1 1 and the terminals of the sides'of the V-shapedelementslO and 12 havesonneetion by. means of pins 13.

The link members 14 and 15 have receive the pivot bolt 11, as shown more particularly in Fig. 3 of the drawings.

' f 'oc'ated, respectively, on opposite sides of the fencestruc turcA, and extending at right angles-thereto, is a pair ofopposed operatrods s and 19. ,Therods18 and 19 have those ends that are extended fin the direction of the ,fence structure A, extending through thespaces'between the opposed arms ofthe V shaped elements 10 and 12' andare connectedfto the'inne'r ends of the respective -,gate members 14: and 15, shown' ,in Fig. 13.

The outer"endsf of the operating rods 18 and-1 9 extend considerable distances beyond the fence structure A, and have connection with operating'elements 21 and 20, respectively); Each of these operatingelements 21 2 0 consist of an inverted. 'U-shaped portionfh'aving: the lower ends of the sides offsetdaterally, as shown at 22, and ,rotatably positioned in bearings 23. One end of each U- sh'aped.element is continued from .theotfset lateral portion 23 and extended ewe- 1. 1am W hfihe jac n s e Of the U-s'haped element,fand terminally bent laterally, asshown a't 25,. and received by aneye' formed jn the adjacent end of the adjacent operating rod, as shownin Fig. 1. '"A's'snming. a vehicle approaching the gate from the'd'irection indicated by the arrow in ward "wheels will contact with the U-shaped I element. 20, resulting'ln the said U-shaped extends, so as to cited rotation of' the eleelement, being tilted in the direction of the 20 effects movement of the operating rod gate The'tilting ofthe U shaped element inentsuo and 12 to move those arms which have connection withthe ,outer end of the iink e toward the gate.

When a vehicle apwitlrthe laterally extending terminals of the extendedfends 21 oi the U-shaped operating elements 20 and fil and serva to returi'l. the operating elements 20 and 21 to their normal positionafter the gate has been moved to closed position.

pair ofspaced posts 27 are located,.on opposite sides of the fencestructure A and adjacent the U-shaped operating elements 20 and 21 and each 'of the posts has one side provided, at the upper end thereof, with a segmental plate 28l1aving one end projecting above the terminal of the post, and having outer edge curved, as shown at 29. When the gate B is moved to open position, ineither direction, the same will be moved against one ofthe posts 27 and the free end of the latch rod 3 will ride over the element 28 and engage behind the same so as to hold the gate inopen position. Each of the posts 27 has one side provided with a rod '30, which has pivotal connection thereto, as at 31, and the lower end of the rod has connection with one end of the spring 32, and

the upper end of the rod is curved, as shown at33. When the gate is moved to a position so'as' to cause the free end of the latch rod 3 to engage behind one of the elements 28, the said'free end will also engage the outer side of the curved end 33 of the adjacent rod 30, causing rocking of the arm or rod 30, so as to prevent abrupt contact betweenfthe free end of the latch rod 3 and the adjacent rear side of the element 28,

When either of the U-shaped operatingelements 20 and 21 are operated to move the gate tov closed position, the rod 7 will be flexed so as to withdraw the free end of the latch rod 3 from in rear of the element 28, so as to release the gate and permit the same to be moved to closed position.

. It will be understood that various minor changes in the construction and arrangement of parts can be had without departing from the spirit of the invention as claimed.

Having thus described our invention what we claim as new is:

1. The combination'with a. swinging gate,

,agatepost, of, a latch carried by the and one above the other, means necting the latch to the ll-shaped rotatable gate, means on the post for engagin the latch when the gate is movedin one irection so as to hold the gate against movement, a vertically disposed lever having its upper end pivoted to the gate and its lower end depending below the gate, an elongated bar formed of resilient material disposed below the gate and having one end connected to the lower end of the lever, a rotatable element, an arm connecting the other end of the resilient bar to the rotatable element, and operating means connected to the rotating element and adapted when operated to effect rotation of the element so as to flex the resilient bar and efi'ect the withdrawal of the latch from the means on the post to admit of movement of the gate.

2. The combination with a gate and a latch therefor, of a pair of rotatable V- shaped elements arranged in spaced relation for conelements and including an arm extending between the apices of the \I-shaped elements, a pair of slotted intersecting links located between the V-shaped elements, a bolt extending through the apex portions of the V-shaped elements and through the slots in the links, links pivotally connected between the opposing sides of the V-shaped elements at the outer ends thereof, and hav ing connection with the. first mentioned links, and oppositely extending operating rods having connection with the points of connection between the first and secondmentioned links.

In testimony whereof we alli-x our signatures in presence of two witnesses.-
