Specification of LettersPatent.

Patented Dec. 10, 1912.

Application led May 18, 1912. Serial No. 698,271.

Torelli whom it may concern:

Be it known that I, ALLEN E. WHET- sToNn, a citizen of the United States, residing at Wood Lake, in the county of Cherry and State of Nebraska, have invented certain new and useful Improvements in Gates, of which the following is a specification.

rThe invention relates to that type of gates wherein the counterbalanced lever is connected by a link to effect manipulation of the gate, and the object in view is the impartation of a thrust to the gate at such point as to enable the lever mechanism to attain the maximum leverage effects and to thereby swing the gate from closed position with a minimum expenditure of stress.

For a full understanding of the present invention, reference is to be had to the following description and to the accompanying drawings, in which Figure 1 is a view in elevation of a gate constructed in accordance with my invention, showing in dotted lines the movement of the gate from its closed to open positions, a portion of the supporting standard being broken away; and Fig. 2 is an end elevation of the same.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

In carrying out the invention I employ a gate 1 which may be of any ordinary construction and shape best suited for the purposes for which is is desired. In the-draw ings, however, the gate comprises the usual horizontal frame members 2 and a diagonal brace member 3 suit-ably secured in the frame of the gate itself. The gate 1 is pivotally mounted at its lower inner corner on the cross-rod 4 mounted in thelo-wer portion of the vertical spaced standards 5 between which the gate is adapted to be operated. The opposite end portion of the gate preferably rests upon a suitable supporting block 6 adjacent the jamb posts which are not shown in the drawing.

At a suitable point in one of the vertical standards 5 is located a pintle 7 upon which is fulcrumed intermediate its ends, a balancing lever 8 which extends downwardly at an incline and has provided on its free end a counterweight 9, the latter being preferably slidably mounted on said lever for adjusting purposes. The opposite extremity of the inclined balancing lever 8 is pivotally connected with one en d of the link-bar 10,

`and closing said gate. The particular point of pivot of the gate opposed to the point upon which the balancing lever exerts its force is important, as will be obvious to anyone skilled in the art to which this device refers.

In the actual use of my invention, the gate extends in the usual manner across the road-` way, beside which may be provided the usual approach posts at both sides of the gate but since these are of the ordinary conventional usage they have not been shown in the drawing. An operating ropev 12 extends from lthe approach posts aforesaid to the upper frame member of the gate 1 where it is secured, as indicated at 13, passing over a pulley l-l swiveled on the upper cross-bar 15 connecting the spaced standards 5. From the foregoing it will be obvious that to operate the gate to open or close the same, a very slight pull is exerted upon the rope 12, imparting a slight momentum to the gate, which, by action of the weighted balancing lever, moves on its pivot in a vertical plane until itassumes its ended position, shown in dotted lines in Fig. l. Having in view the inclined position of the balancing lever and its link connection, the gate is shoved by the former throughout its movement and the slight momentum which is given thereto when the rope l2 is actuated, naturally tends to prevent any likelihood of the gate from stopping at its center of movement.

There are numerous advantages of my particular construction, some of which have hereinbefore been mentioned, and it is to be noted that by reason of the incline of the balancing lever 8, it is in an operative position both when the gate is closed and when opened, and when in the latter position only a minimum amount of space is required to accommodate the same. The spaced standards 5, between which the gate operates, act

as a guide therefor throughout its Inovement, in an obvious manner, and prevent any side swaying when operated while the wind is blowing.

Slight modifications may readily be made in the structure without departing in any 1 way from the spirit of the invention and within the scope of the claims hereto appended.

Having thus described the invention, what is claimed as new is: Y

l. The Combination, with a standard, of a gate pivotally mounted to swing vertically, a lever pivoted tothe standard in the vertical line of the pivot of the gate and spaced therefrom and extending outwardly from the pvot across a portion of the gate, and a link pivoted at its lower end to the lower end ofthe lever, said link extending upwardly Copies of this patent may be obtained for and .being pivoted to the gate at a point above the horizontal line of the pivotal connection of the lever to the standard.

2. The combination, with a standard, of a gate pivoted adjacent the standard, a lever pivoted to the standard and extending downwardly on an incline past a portion of the. gate, and a link pivotally Connected to 'the lower end portion of the lever and eX- tending upwardly to and pivotally connected with the upper portion of the gate adjacent the free end thereof.

In testimony whereof I aIiX my signature in presence of two witnesses.
