YTo /r/Z l/'/om/ if 71mg/ wlw/1771..'

Re it known that we, Guantes lV. VAN Dn Atmen and Ronniz'r T. J nNNicv, citizens ot' the United States, and residents ot Two Riv- 1 slotted at 2O to embrace the lower end otl said ers, in the county of Manitowoc and State of `Wisconsin, have invented a new and Improved (iate, ot' which the Following is a full, clear, and exact description.

Our invention relates to gates, and more particularly to mechanism t'or opening and closing' the same. its principal objects are to provide a. simple and eti'ect-ive mechanism t'or this purppse.

lt consists in thc various Vfeatures and coinbinations hereinafter described and claimed.

he terence is to be had to the accompanying' drawing-s, forming a part ot' this specilication, in which similar characters ot' reference indicate correspomling' parts in all the tigures.

Figure l is a perspective view ot' a portion ot a tence and a gate embodying' one forni ot' our invention. Fig'. '2 is an enlarged broken elevation showing the gate in its open position. Fig. P) isa broken detail` in top plan, otl the operating' mechanism. Fig. l is a horizontal sectional detail showing the lower support ot' the gate; and Figs. 5, 6, and T are details in horizontal section illustrating. respectively. the position ot' the elements when the gate is closed, when it is in an intermediate position` and when open.

A tence is designated by the letter F, there being in said tence an opening' which is closed by a gate (l. .-\t one side of the gate-opening' is a post l), preferably extending somewhat above the height ot the ordinary tence, and upon this post are mounted supports, here .shown as eyebolts lil, ll. l2. and 13, through the openings ot' whichextemls a vertical spindle li. A\bout this spindle swings the gate (i, this heilig here illustrated as consisting' otl an outer trame formed ot' bent channel-iron, furnishing top and bottom bars 1l and l5, respectively. and a vertical end bar lo. It is provided with horizontal members 1T, suitably spaced and extending through openings in the end bar and in a series ot' vertical members 18 and diagonal stays '19. At the inner end ot' the top bar is an opening which coperates with the spindle, and the lower bar is spindle, this slot being closed outside the spindle by some such device, as a Cotter Ql. The lower bar normally rests upon the support lo; but it' it desired to raise. the gate so that it may operate al1 a greater height to enable it, t'or example., to move above snow the cotter may be removed and the lower bar swung out, whereupon the upper bai' may be slid upon the spindle until the slot .20 comes above the support ll, when it may be again brought into cooperation with the spindle and secured in place bythe cotter. The upper supports l2 and 123 serve asa bearing tor the spindle, and the distance between them is sutiicient to permit this transfer ot' the gate to the second support.

A latch is provided t'or the gate, here shown as consisting ot' a flexible metallic bar Q2, pivoted at 9.2 to the end ot' a bracket 23, lixed to the lower bar l and guided at its upper end by a continuation 2l ot' one otl the horizontal members l T, this extending through a slot in the bar 22. A nut 26 is preterably threaded upon the end ot' the extension to limit the outward movement ol the latch. The upper end ot' the spring-bar 22 may have formed upon it a handle 2T t'or convenience in operation by persons on t'oot. The latchbar may coact with an inclined catch 28, lixed at one side otl a post ,n at the opposite side ot' the gateopening from the post P.

At the side to which the gate is to swing', it being' situated at substantially ninety degrecs from the post p and at the same distance trom the post l" as said post p. is a post or upright Q9, connected near its upper end with the end ot' the post l by a cross-bar 3l). This upright 29 carries a catch 29 for engagement with the latch-bar '22 when the gate is open. VFrom each end ot' the cross-bar projects an arm 3l, here shown as inclined up-4 wardly therefrom at a slight angle and for l the sake of strength and lightness consisting of opposite side pieces 32 32, joined at their ends and connected by an intermediate crossbar or stay 33. They may each be braced by a diagonal stay 34, secured to the stay 33 and to the adjacent post. Fulcrumed at 35 upon the end of each arm is a lever 36, at the outer extremity of which is a pendant 37, carrying a handle 38. From a point near the inner end of this lever rises a projection or arm 39, and these opposite arms are joined by connectors or rods 40 to the opposite ends of an operating-lever 41, fulcrumed at 42 between the cross-bar 30 and a bracket 43, which may be secured to the post P at one end and to the cross-bar at the other. The rod 40, which extends farthest from the lever 41, may be supported by a guide 44, carried by the arm 31 at that side of the gate.

Fixed to the upper end of the spindle is an arm 45, which is connected at its outer extremity by a link 46 to the lower end of the lever 4l, this arm and link together forming a toggle-lever. The arm may also by its contact with the support 13 serve to fix the position of the spindle in the support. Connected to the operating-lever between its fulcrum and the point of attachment of the toggle is a spring 47, fastened at its opposite end to the post P and exerting its force to maintain the gate in one or the other of its extreme positions, as will be hereinafter described, and at the same time to hold the levers 36 raised. The attachment of the spring to the post is preferably through a threaded rod 48, extending through an opening in said post and having at the outer side thereof a nut 49, the rotation of which will serve to vary the tension of the spring.

Fixed to the spindle at a point here shown as substantially midway of the gate is an arm 50, which is connected by a suitable link 51 to a collar 52, fast upon an operating member or bar 53, extending longitudinally of the gate. This bar is mounted to slide in the bar 16 and members 18 and preferably passes freely through openings in the stays 19. At the opposite extremity of this bar is a threaded portion 54, which extends through an opening in the latch and is lixed with relation thereto by opposite check-nuts 55 55.

When the gate is closed, the toggle will occupy the position illustrated in Fig. 5 of the drawings. Now if it is desired to open the gate either of the handles 38 may be drawn downward. This depresses the lever 36 and through the connecting-rod and the operatinglever straightens the toggle against the tension of the spring, which results in a rotation of the spindle. This through the arm 50 and link 51 first moves the operating-bar 53 from the spindle, releasing the latch-bar from the catch 28, then the arm continuing its revolution swings the gate. This straightening of the toggle is effective to move the gate until its elements are alined with one another, as is illustrated in Fig. 6; but the momentum of the gate will be suflcient to swing it by this intermediate point, which is at substantially forty-iive degrees from its closed position, causing the toggle to break upon the other side. This brings the tension of the spring upon the gate in such a manner as to continue its movement, and this causes it to contact with the upright 29, at which point the latchbar engages the catch 29u and locks it in place, the operating elements occupying the position shown in Fig. 7. The closing of the gate may be accomplished in exactly the same manner, the toggle in this case merely moving in the opposite direction.

It will thus be seen that the gate may be operated in either direction from either side by a person in a vehicle and that at either of its extreme positions it will not only be locked by the catch provided, but will be held by the tension of the spring, which assists in opening or closing it. The gate and its operating -mechanism is, moreover, extremely simple and durable.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination with a gate, of a spindle about which the gate may swing, an arm fixed to the spindle, an operating-lever connected with the arm, a spring exerting its tension upon the operating-lever, and means for transmitting the movement of the spindle to the gate.

` a toggle connecting the lever and gate, a spring acting upon the lever, and means for transmitting the movement of the spindle to the gate.

4. The combination with a gate, of a spindle about which the gate may swing, a lever, a toggle connecting the lever and gate, a spring acting upon the lever, means for adjusting the tension of the spring, and means for transmitting the movement of the spindle to the gate.
