A. ROSS. SWINGING GATE.

No. 472,716. Patented Apr. 12-, 1892.

UNITED STATES PATENT OFFICE.

SWINGING GATE.

SPECIFICATION forming part of Letters Application filed August 29, 1891.

To all whom it may concern:

Be it known that I, ALVA Ross, a citizen of the United States, residing at Virden, in the county of Macoupin and State of Illinois, have invented certain new and useful Improvements in Swinging Gates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to swinging gates for driveways, and especially to that class in which elevated ropes are employed to lift the latch to swing the gate.

Heretofore it has been customary to use a lever having one arm pivoted to the gate and the other arm provided with rollers or loops to receive the operating-rope, the lever being loosely pivoted 011 the rear gate-post, so as to have endwise play and swing to the right or left in opening or closing the gate. It has also been customary to provide the latch-post with means for arresting the end of the gate to prevent it from swinging back and forth before looking. It is my purpose to so 'ar range these particular parts of the gate as to obtain more efficient action, whereby its operation will be made more satisfactory.

WVith this purpose in View my invention consists in the peculiar features and combinations of parts more fully described hereinafter, and pointed out in the claim.

In the accompanying drawings, Figure 1 represents a front perspective view of my complete invention, in which the gate is shown closed; Fig. 2, a similar view showing the gate open, and Figs. 3 and 4 detail views of the latch mechanism. Fig. 5 is an enlarged detail view of the pulleys employed.

The gate ais hinged to swing upon a post I), and is actuated in opposite directions by means of a slotted rod or lever 0. At the rear of the gate-post b is located a taller post d, having upon its top a fulcrum e, which passes through an elongated slot f, which slot enables the lever to move endwise upon the post. The gate is provided with a latch g, which engages a keeper h on the latch-post 2' and is normally held down by springj.

The means for imparting motion to the gate, and at the same time liberating the latch, consists of a rod, cord, or wire is, extend- Patent No. 472,716, dated April 12, 1892.

Serial No. 404,132- (No model.)

The ropes pass through orifices t in a guide-block t, fixed to the lever c, thence around groove-pulleys u, swiveled to a block a on the rear end of the lever. These pulleys are provided with guards to", which prevent the ropes from slipping oif. By thus swiveling the pulleys they are allowed to adapt themselves to the different positions of the rope without binding the latter or interfering in any way with its free action. The ropes then pass through pulleys a on the underside of overhanging arms 0, attached to the top of the posts m m', and from these pulleys n they pass downward in a diagonal direction to pulleys n on the side of the posts. Thence they pass downward and upward to form a loop q, and have their ends fastened to a nail r, and a weight 8 is hung in the loop to keep the ropes taut.

The means for stopping the gate whenever it comes opposite the post i consists of apair of gravitating tumblers 'v, hung upon pivots o upon opposite sides of a V-shaped projection to, which is interposed between the upper part of the tumblers. located within the recess 00, so that they lie back of the face of the post and permit the gate to swing freely by them when not en-' gaged by the latch. The adjacentinner edges '0" of the tumblers are curved to permit the latch to slide freely over them in the releasing operation. The upper part of the adjacent face I)" comes in contact with the projection w Whenever the latch strikes the op posite face 0', as seen in Fig. 3, thus limiting the inward play of the tumbler and preventing the latch, and hence the gate, from swinging past the post. When the tumbler is thus held against the projection to, it serves as a guide to direct the latch into the recess w in the keeper, and after the latch drops the tumbler gravitates back to an upright position and will allow the latch when raised to pass freely away from the post in either di- These tumblers are pulleys n, and '11.

rection. Both tumblers are exactly alike, and when the gate swings toward the post from the opposite direction the opposite tumbler performs precisely the same functions in arresting the movement of the gate.

When the gate is closed, as in Fig. 1, it is opened by pulling on the cord it" between the This actuates the bellcrank lever on the end of the gate, lifts the latch up between the lower ends of the turnblers, and simultaneously draws on the rear end of the lever 0, thereby forcingthe opposite end away from the operator and toward the opposite side post m. A continued draft on the rope throws the end of the gate against said side post, to which it is held by akeeper 2. When the gateis thus open, it will be seen that the actuating-lever c is out of parallel or at an angleto the gate, so that lateral strain is brought to bear upon thelatter, and the closing operation is consequently greatly facilitated, for if this lever should lie parallel with the gate when open the endwiise strain upon the bar would be insuflicient to close it. The closing operation is performed by grasping the rope is between the loops on the side post and pulling the rope downward, thereby bringing the lateral strain upon the rear end of the actuating-lever c and at the same time actuating the bell-crank lever on the front of the gate andliftingthe latch. Then the gate said rope It will lift the latch and swing the 'leverprevent the rope from catching in the pulley-guards and enable the rope to pass over the pulley with facility.

Having thus described my invention, what I claimas new, and desire to secure by Letters Patent, is

The combination, in a swinging gate, of a gate hinged to a gate-post and provided with an actuating-lever fulcrumed on a separate post at the rear of the gate-post, whereby increased leverage is obtained when the gate is open, swiveledpulleysv attached to the rear of said lever, ropes passing over said pulleys and having their opposite ends connected to side posts, and a rope connecting them with a latch upon the gate, all arranged in the manner and for the purpose set forth.

In testimony whereof I affix my signatu-rein presence of two witnesses.

ALVA ROSS.
