Be it known thatI, IVILLIS E. NEWTON, a citizen of the United States, and a resident of lNewburg, in the county of Jasper and State of Iowa,have invented a new and useful Farm- Gate, of which the following is a specilication.

The object of this invention is to provide an improved gate and improved means for sliding said gate longitudinally and guiding and supporting said gate during its movements.

My invention consists in the construction, arrangement, and combination of elements hereinafter set forth, pointed out in my claim, and illustrated by the accompanying drawings, in which- Figure 1 is a perspective showing my gate in an open position and mea-ns whereby the same may be operated. Fig. 2 is a planof the mechanismwhereby the gate is operated by engagement of a vehicle. Fig. 3 is a detail elevation ofthe spring mechanism for relieving the shock occasioned by the sudden operation of the gate.. Fig. 4 is a view illustrating a clutch mechanism employed in the operating mechanism.

In the construction of the device, as shown, the numerals 11 designate supporting-posts and limit and determine the degree of travel of the gate. The posts l0 11 are connected at their upper ends by a rider 12, and ou one side of said rider is mounted a track 13, preferably made of metal and laterally removed a short distance from the face of said rider. Hangers 14 15 are provided and carry on their upper ends grooved rollers 16,17, which rollers rest and travel upon the upper edge of the track 13. The lower end portions of the hangers 14 15 are connected to the upper ends of stiles 17 18, forming the ends of the gate. The lower ends of the stiles 17 18 are connected by parallel bars 19, separated a slight distance and forming the lower edge of the gate. A center post or stile 2O is situated midway between the stiles 17 18 and is connected at its lower end to the central portion of the bars 19 and secured to the end portions of said bars by braces 21 22, extending from said end portions to points of attachment to the stile near its upper end,l thus forming a truss to support the central portion of the gate. Bars 23 are horizontally placed in parallel oscillation therein.

planes and are connected to the stiles and braces to form the middle and upper portion of the gate.

Posts 24 25 are provided and located at the opposite side of the roadway or passage from the post 10 and on opposite sides of the gate. The post 25 is employed to receive and support the ends of the wires or boards forming the fence at that side of the roadway. The upper end portions of the posts 24 25 are bifurcated, and levers 31 are mounted for The end portions of the levers 30 31 adjacent to the gate are confined within the bifurcations of the posts 24 25 and move vertically therein when the levers 30 31 are oscillated. The extreme inner end portions of the levers 30 31 extend almost to the spacethrough which the posts 17 18 of the gate travel, and connecting-rods 32 33 are hinged thereto and depend therefrom. A slot 34 is formed in the upper portion of the stile 20, andan operating-lever 35 of U shape traverses said slot and is pivoted at its ends to the lower portions of the posts 24 25.

The end of the U-shaped frame formed by the operating-lever 35 is movable vertically in the slot 34, and said slot is enlarged laterally at its lower end to form seats for the end of the frame when the gate is closed or entirely open. By means of the seats in the lower end of the slot 34 the lever is' retained against elevation by any movement or oscillation of the gate, thereby locking the gate against longitudinal movement until such time as the lever is elevated in the desired manner. The lower ends of the connectingvrods 32 33 are pivotally connected to the central portions of the opposite bars or arms of the lever 35.

Guide-posts 3G are set midway between the posts 24, 25, and l0, and guide-posts 37 37 are set midway between the posts 24, 25, and 11, all of which guide-posts are short and have journaled on their upper ends antifrictionrollers 3S, designed to engage the eXtreme outer faces of the bars 19 and guide and strengthen the gate in its longitudinal movement.

In order to open the gate, it is necessary, if on foot, to elevate the lever 35 manually and then move the gate longitudinally. When it is desired to open the gate While mounted,

the operator depresses one or the other of the outer ends of the levers 30 3l, thus oseillatin g the levers on their fulcrums, elevating the connecting-rods 3f 33, and elevating and carrying the lever 35 through an arc, during which operation the cross-head or closed end of the lever 35, engaged in the slot 3l, moves vertically in said slot and impels the gate in the desired direction until the said lever passes a vertical plane, after which the momentum attained in the initial operation carries the gate into the position shown. Duringthe lon gitudinal movement of the gate the rollers 1G 1G travel 011 the track 13, which, being formed of metal and of slight transverse dimension, offers but slight support for snow, sleet, or other obstruction to the travel of the wheel.

'lhere are provided, in addition to the construction heretofore set up, arms 50 5l, fixed to and extended in opposite directions from those portions of the lever 35 pivoted in the posts Q-.t 95. The arms 50 5l extend at right angles to the path of travelof the gate to such distances as will exceed the length ot' an ordinary vehicle and the team attached thereto. The outer end portions of the arms 50 5l are provided with miter-gears 52 53, which mesh with miter-gears 54 55, respectively pivoted 0n vertical axes in boxes 56 57. Arms 58 59 are pivoted to the axles of the gears 5l 55, and extend therefrom transversely of the roadway and across the line of travel of at least one wheel of an ordinary vehicle. The arms 5S 59 are provided with sleeves CO, loosely mounted thereon and revolublc relative thereto. rThe sleeves 60 are about four incles in diameter and are placed from three to six inches above the surface of the ground. Owing to the location and size of the sleeves the wheels will not ride thereon but will push the same downwardly and forwardly until the arms 5S 59 are at such oblique angles to the roadway as that the wheels will pass the same. In the forward movement of the arms the sleeves are depressed into contact with the ground and roll thereon, thus flexing the spring (il to such an extent as that said spring will throw the arms back when the wagon-wheel has passed. Springs 6l are mounted in the boxes 56 57 and impinge against the under side of the arms 5S 59 and tend to maintain said arms in normal positions transversely of the roadway and in planes solnewhat elevated from the surface of the ground. A ratchettooth 62 is formed on each of the arms 5S 59 and is designed for engagement at times with ratchet-teeth on the gear-wheels 5i 55, but

said teeth normally are elevated above the wheels and are maintained at such elevation by the springs 6l.. An eye 63 is formed in the operating-lever 35, and a curved bar (it is loosely mounted therein and connected at its ends to a right-angled frame G5, loosely mounted on those portions of the operatinglever connected to the arm 5l. Expansive coil-springs G6 G7 are mounted on the curved bar (il and conlined between the ends of said bar and the lever In the practical operation of the gate the triangular frame strikes the ground or a block provided therefor, which results in a compression of one or the other of the springs GU 67 and a consequent cushioning of the cessation of movement of the gate. The gate being closed, as a vehicle approaches one of the wheels of the vehicle engages the sleeves 60 on the adjacent bar 58 or 59 and moves said bar laterally into the position shown by dotted lines. In the movement of the bar laterally it is also moved downwardly, thc tooth thereon engages with the ratchet of the gear and rotates said gear, which in turn rotates the gear meshing therewith and the arm connected thereto and throws the operating-lever and the gate thereon into an openl position. lVhen the arm has been moved laterally a suliicient degree, the wheel passes and the spring connected to said arm throws the same back into the transverse position and out ot engagement with the ratchet on the gearwheel. 'lhe further travel of the vehicle actuates the lever by engagement with the bar on the other side of the gate to restore said gate to a closed condition.

I claim as my invention- A sliding farm-gate, comprising a traveling gate having a vertical slot in its central portion, an operating-lever fulerumed adjacent to said gate and traversing said slot, arms formed on said operating-lever, intermeshing miter-gears connected with said arms, laterally-extendin g arms clutched to said gears and extending over the roadway, springs for normally retaining said arms in and returning said arms to desired positions and sleeves on said arms for engagement by vehiclewheels, as set forth.
