GATE.

SPECIFICATION forming part of Letters Patent No. 651,911, dated'June 19, 1900.

Application filed October 19, 1899. Serial No. 734,086. (No model.)

To all whom it. may cancer/ Be it known that I, ALBERT WILLIAMS, a citizen of the United States, residing at Fredonia, in the county of Louisa and State of 'Iowa, have invented a new and useful Gate,

' and to provide a simple, inexpensive, and

efficient one of great strength and durability adapted to be readily operated and capable of positively closing after it has been swung downward beyond a horizontal position.

A further object of the invention is to enable the gate to be securely locked at each side when in its closed position and to arrange the operating-rope so that both latches will be simultaneously operated.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a gate constructed in accordance with this invention and shown closed. Fig. 2 is a side elevation of the same,the gate being open. Fig. 3 is a vertical sectional view illustrating the arrangement.- of the locking mechanism.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a gate having vertical end bars 2 and 3, extended to form levers and pivoted by bolts 4 and 5 to posts 6 and '7, whichare located at the ends of the gate, as clearly illustrated in Figs. 1 and 2 of the accompanying drawings.

The gate is composed of short vertical bars 8 and 9 and horizontal rails 10, arranged in pairs, as clearly shown in Fig. 1 of the draw ings, and secured to the opposite faces of the vertical bars 8 and 9, which are alternately wide and narrow to bow the rails and form a truss-like structure, whereby the gate will and is located aconsiderable distance above the pivots 4 and 5 in order to afford ample space for the passage of vehicles and at the same time enable comparatively-short posts 6 and 7 to be employed for this purpose.

The gate is counterbalanced to a greater or less extent, according to its position, by a pair of oscillating weights 11, provided with rods or stems 12, having eyes 13 at their upper ends and pivoted to the upper arm of the levers or bars 2 of the gate by bolts 14 or other suitable fastening devices. When the gate is closed, the weights lie between the bars 2 of the gate and are arranged below the pivots, so that the gate proper or lower portion of the revolving structure isheavier than the upper portion and will remain closed and will close positively and automatically when the gate in closing is swung downward below a horizontal position. When the gate is in a horizontal position and the weights are exerting their greatest power, the said gate is practically counterbalanced; but its momentum will carry it beyond such horizontal position and the weights are swung inward and exert less power, so that the gate will close. When the gate is open, the weights extend beyond the levers or bars 2 and fully counterbalance the gate, so that there is no liability of the same accidentally closing.

When the gate is closed, it is locked in such position by a pair of pivoted latch-bars 15, arranged at and extending beyond the ends of the gate and engaging keepers 16, secured to the inner faces of the posts 6 and 7 and provided at their upper edges with suitable recesses or shoulders. The latch-bars are connected by links 17 with arms 18 of a rock shaft 19, and they are arranged within suitable guides or frames 20. The rock-shaft 19, which is arranged horizontally near the top of the gates is journaled in suitable bearings 21 and is adapted to be swung upward by an operating-rope 22,whereby the latch-bars will be disengaged from the keepers to unlock the gate. The lower end of the operating-rope 22 is secured to the adjacent arm 18 of therockshaft, and the said rope passes upward therefrom and extends through a suitable guide 23, arranged at the upper end of the adjacent bar or lever 2. The gate opens in one direction, and it will be apparent that when the op- 4 close it.

"5'. the gate to close positively and automatically.

crating-rope is-pulled upon both latcheswill' be simultaneously operated andthe gatewill beswun g upward to a perpendicular position above the posts 6 and 7. Any suitable stop may be provided tolimit the movement of the gate, and this stop is preferably provided at a suitable point on the operating-rope. When the gate is open, a similar pull on the operatin g-rope will close it.

It will be seen that the gate is simple and comparative]y-inexpensive in construction, that it possesses great strength: and dnrabil ity, and that itis easily operatedto open and It will also be apparent that the weights counterbalance the gateduring the openingand closing of the same, that they hoTd'the-gate in its o-pen position, and permit Furthermore, the gate is secured at each end when closed, and both of the latches are simu-' ltaneou'sly operated by the rope, which may be" arranged in any direction that will give the desired pull. The rope may extend from the gate at right angles to the same a suffiop'ened and closed, and the direction of the rope may be then changed to arrange it within convenient reach of persons on foot and in vehicles.

Changes in the form, proportion, size, and theminor details of construction within the scope-of the appended claims may be resortedto without departing from the spirit or sacrificing any of theadva ntages of this invention.

What is claimed is I. In device of the class described, the combination with'suitable posts or supports,

of a gateprovided with vertical levers extend- I ing upward fromitand-pivoted between their ends to the postsor supports, said. gate being adapted to oscillate from a vertical position,

, below the pivots, to a vertical position above the pivots,and the swinging weights connect- .ed to the inner faces of the levers at a point above the pivots, substantially as and for the V purpose described.

2. In a device of' the class described, the combination with posts or supports, of an os- "cillating gate mounted thereon, latches arira-nged at the ends ot the gate, a rock-shaft journaled'on the gate and provided with arms connected with the said latches, whereby the latter will be simultaneously operated, and

operating mechanism connected with the rock-shat t and adapted to open and'close the gate, substantiallyas described.

3'. In a device of the class described, the,

mounted on the gate at theendsthereof,a-1-ock- I shaft journaled-on the gate and provided with arms connected with the latches, and an operating-rope connected with one eithe arms of the rock-shaf t and with the upper portion of one of the bars of the gate, substantially as described.

In testimony that I claim theforegoing as my own I have hereto aflixed my signature in the presence of two witnesses.

ALBERT WILLIAMS.
