AUTOMATIC GATE.
SPECIFICATIONforming part of Letters Patent No. 253,232, dated February '7, 1882.
Application filed September 27, 1880. (No model.)
T o'all whom it may concern Be it known that I, EPHRAIM E. SrrrLEn, of Amity, in the county of lllontgomeryand State of Ohio, have invented certain new and useful Improvements in Automatic Gates; and I do hereby declare the following to be a full, clear, and exact description of the same.
My invention is an improvement in carriage way gates which are automatically opened and closed by the passage of the carriagewheels over the operating-trips.
The novelty of the invention consists in the construction and arrangement of the operating parts, as will be herein definitely set forth.
In the accompanying drawings, Figure 1 is a front elevation of my improved gate. Fig. 2 is a plan view of the same. Fig. 3 is an inverted plan view of the lower hinge-bracket and operating-levers. Fig. 4 is a perspective view of one of the trips and its mechanism. Fig. 5 is a detached view of the latch-plate. Fig. 6 is an enlarged plan view of the upper hinge and its connections.
A represents the gate, of ordinary construction, and B and O the gate-posts, to the former of which the gate is hinged. The upper hinge is composed of a pintle, D, attached to the upper end of the gate, as shown, and engaging with an eye formed in an adjustable pivoted arm, E. This arm E is pivoted at (0 upon a horizontal semicircular bracket-plate, F, attached to the post B, and its rear end is enlarged at I), and serrated upon its under side to engage with corresponding serrations, 0, formed upon the plate F, as represented. A
thumb-screw, d, passing through a segmental slot, 6, in the enlarged end of the arm E, serves to clamp the arm to the plate. The purpose of this construction is to enable the position of the upper hinge to be adjusted in order to equalize the swinging of the gate, and this is done by simply looseningthe thumb-screw and setting the arm E by turning it upon its pivot to the required-position. When properly set the serrations are re-engaged and clamped by the thumb-screw.
The lower hinge consists of a bracket-pintle, G, attached to the lower end of the gate, as
shown, and entering a double curved slot in.
the horizontal bracket-plate H, which is attached by bolts or otherwise to the gate-post B. The shape of this double curved slot f is seen in Fig. 3. W'hen the gate is closed the Between the racks t and tongues j is a re-- cess, 7.", cut out of each lever, through which the lower end of the pintle Gr passes; and upon each lever is a hooked finger, l, the one resting upon the other when the levers are in the position indicated in Fig. 3, when the gate is closed. The operating-rods L extending from the trips have their inner ends attached in any suitable manner to the rear ends of the levers J K. When either of the tripsis pressed toward the gate by the wheels ot'an approaching vehicle the rod on that side is pushed forward, causing the lever J or K, as the case may be, to swing around upon its pivot. As it turns the hooked finger l partly encompasses and carries with it the pintle G out to the end m of the slot. This act-ion of the lever tilts the gate in such position that it swings open by its own gravity. Passing on through, the vehicle presses the other trip away from the gate, thus drawing on the rod and causing the levers J and K to swing back to their former position and to carry the pintle G with them, which action again throws the gate so that it swings shut again by its gravity. The trips M are ordinary single trips arranged upon the side of the roadway in the usual or any suitable manner. Each is provided with a crank-arm, n, from the upper extreinity of which chains 0 0 extend to either side, and are attached to the rods L through adjusting-holesp by hooks r. -When the gate is closed the outer chains, 0, are taut, while the inner chains, 0, are slack. WVhen the gate stands open the outer chains are slack and the inner ones taut. To hold the trips upright ready for the wheels of a vehicle at all times, I employ a weighted arm, P, pivoted in or to a post, R, at the side of the trips, and having a link, t, connecting the crank end of the weighted arm with the end of trip-cranks, as seen. When the trip is pressed down the weighted arm is raised, and when the trip is released the weight of the arm returns it to an upright position, as will be readily understood by reference to Fig. 4.
To latch the gate I employ the metal plate A, Figs. 1, 2, and 5, which is bolted to the post 0 in any suitable manner, and contains upon its front face the horizontal ledge a, with depressed ends, and above this two segmental flanges, b, which serve as stops.
'Upon the gate is a spring-latch, B, of any suitable construction, with an operating-handie, 0, and an engaging nose,0. \Vhen the gate is closed the nose of the latch is retained between the lower ends of the segment-stops b and above the ledge a. When, however, the gate is tilted by a vehicle this engagement is broken by the tilted position of the gate and it swings open. In closing, the nose of the latch strikes either of the stops b, and is guided down under it until, passing its end, it flies up and is caught in the concave side of the opposite stop and settles back between the two.
In opening the gate by hand the handle 0 is used in the ordinary way. Especial attention is called to the levers J and K, formerly described, the construction of which is such that while the one moves the other, yet there is lost motion in their enga genient, so that the one acted on by the rod moves a little in advance of the other. The purpose of this is to cause the pintle G to be caught and carried by the advance lever, and thus always throw the gate away from the vehicle.
Having thus fully described my invention, I claim- 1. In an automatic gate, the combination, with the lower pintle, G, and the operatingrods L, of the slotted plate H, leversJ and K, meshing together with lost motion, and having the hooked fingels l, substantially as and for the purpose specified.
2. In an automatic gate, the adjustable upper hinge, consisting of the pivoted arm E, with an enlarged serrated end, I), in combination with the pintle D and bracket F, having corresponding serrations, and thumb-screw d, substantially as set forth.
3. The combination, with the single trips M and operating-rods L, of the adjustable actuating-chains 0 0, Weighted lever P, and link t, substantially as and for the purpose specified.
In testimony whereof I have hereunto set my hand.
