GATE.

SPECIFICATION forming part of Letters Patent No. 781,964, dated February 7, 1905.

Application filed October 22, 1904. Serial No. 229,524.

To all 'IIIII/O'IH/ 7'15 Duty concern.-

Be it known that I, TVILLIE L. NOR'IIIAM, a citizen of the United States, residing at Arlington, in the county of Bush and State of indiana, have invented new and useful Improvements in Gates; and 1 do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to swinging gates, particularly to the larger sizes that are adapted to be elevated more or less for avoiding snow-drifts, for grading live stock, or for other purposes, the invention having particular reference to various features of construction relating to the framing of the gate proper, to the hanging and elevating devices, and to the latching appliances thereof.

.larticular objects of the invention are to provide strong and light-weight gates, improved hanging apparatus for the gates, and improved means for elevating and holding the gates in adjusted positions; and a further object is to provide inexpensive, durable, and economical gates having such improvements which may be easily operated.

\Vith the above and other objects in view the invention consists in a gate provided with an improved roller-bearing normally supporting the weight of the gate, a hinge-rod, and rollers or wheels engaging the hinge-rod and together holding the gate in substantially level position, the gate being also provided with a pulley or wheel, a cable, and a lever or similar device for adjusting the gate to various positions above the normal position thereof.

The invention consists, further, in the novel parts and in the novel combinations and arrangements of parts, as hereinafter particularly described and claimed.

Referring to the drawings, Figure 1 is a side elevation of a gate including the hingepost and the latch-post therefor having the improvements embodied in the construction thereof; Fig. 2, an elevation of the free end of the gate; Fig. 3, a fragmentary side elevation showing the gate fully elevated; at, an elevation of the hinge-post; Fig. 5, an clevation of the hinge-rod; Fig. 6, an elevation of the hinge end of the gate; Fig. 7, a fragmentary elevation of the latch-post; Fig. 8, a top plan of the gate complete, a portion of the top rail being broken away; Fig. 9, a fragmentary horizontal section taken a short distance above the bottom rail of the gate; Fig. 10, a fragmentary horizontal section on the line 1 1 in Fig. 1; Fig. 11, a fragmentary horizontal section on the line 2 2 in Fig. 1; Fig. 12, a perspective view of the roller-bearing for the gate and its support detached from the hinge-post; Fig. 13, a fragmentary side elevation showing the gate partially elevated; Fig. 1i, a perspective view of one of the gatelatches; Fig. 15, a horizontal section of the latch-post at the plane of the latches; Fig. .16, a fragmentary elevation of the latch-post and latches, and Fig. 17 a perspective view of the base-plate that supports the latches.

Similar reference characters in the several figures of the drawings designate corresponding parts or features.

In construction any suitable materials may be employed, the hinge-post 1/ and the latchpost I) being suitably set in the ground. The post a is provided with a suitable support A, on which is mounted a roller B and which is placed somewhatabove the ground-surface, so as not to be affected by sand or dust, snow or ice. Above the roller two hinge members a and (I are attached to the post, and a similar hinge member is attached also to the post below the roller and near the ground. A headed hinge-rodf extends through the hinge members 0 (Z c and may be removed therefrom when necessary. A cotter r is inserted in a suitable hole in the lower end of the rod f beneath the member 1/ to prevent accidental upward movements of the rod. A collar 0 is adjustably secured to the rod f by means of a set-screw /1, the collar being below the rollersupport A. The support A comprises an axle that extends through the post a, a nut being applied to the end of the axle against the rear side of the post. On the axle is a collar la, providing a shoulder against the front of the post, the roller B operating freely between the collar and a suitable shoulder of the axle. In the support A is a hole Z, in which is secured a hook-bolt m, that binds the rod 7" against the support and prevents rotation of the rod and also affords a lateral support therefor.

The latch-post is provided with a pair of latches D and D of identical form in order to permit the gate to operate in two directions. The latches are both mounted on a single base-plate E, which has ears n and n in pairs at its rear side, there being a slot 0 in the plate extending between both pairs of ears. Each latch has an arm p, that is pivoted to a pair of the ears, and the latch also has a projection q, that guides a spring 7', which is seated in the post and presses against the latch, the latter having an operating-handle that bears against the base-plate, resisting the spring.

The gate proper comprises a frame including a main bar F, supporting a bottom rail G and a top rail H, to which are attached an end bar I, a trusspost J being attached to the top and bottom rails, and diagonal braces 3 4 5 6 7 8 9 10 attached to the main and end bars and the top and bottom rails; also, horizontal wires 11 12 13 are employed in the usual manner. The end bar I is provided with a latchbar K, although the end bar I itself may be adapted to serve the purpose of the bar K.

A semicircular bearing L issecured to the main bar F and extends about the rod f, soas to bear upon the roller-bearing B, riding thereon and cooperating therewith to support the gate when the latter is in motion and also when at rest in its normal lower situation. A pair of plates 8 and s are attached to the upper part of the gate-frame and extend beyond the bar F and the rod f, and a roller M is journaled between the plates and has a groove 14 guiding the roller on the rod f, the latter being between the bar F and the roller. At the lower part of the gate-frame a pair of angle-plates t and 2/" are secured thereto and extend downwardly beyond the end of the bar F, and a roller N is journaled between the plates and has a groove 15 guiding the roller on the rod f, the latter being beyond the roller.

A pulley 0, having a groove 16, is attached integrally to the roller N; but the pulley may be otherwise connected to the roller, so that both must move together on a common axis. A cable or chain P is attached at one end thereof to the collar 0 and extends under the pulley O to the lever Q, to which it is connected by means of a pin 4;, and the cable is guided to the groove 16 by a guide a, that is attached to the bar F. The lever Q has an end pivoted to a support R, that is attached to the rail G and is arranged at one side of the gate, a similar lever Q being secured to the pivoted end of the lever Q and arranged at the opposite side of the gate. The lever Q is rather a convenience, however, and not a necessity. A movable button S is mounted on the rail G and adapted to be turned so as to lock either one of the levers Q, or Q. A hook T is connected loosely to a pin Q0, that is attached to the rail G, and the free end of the hook is normally supported on a rest in, that is carried by the rail G, the hook having a laterally-bent finger 2, adapted to engage the lever Q to hold it in an intermediate position. The main bar Fis provided with guards 3/ y, that are adapted to engage the rod f in case the rollers M and N should become disengaged from the rod; but the guards may in some cases be dispensed with, they normally having no contact with the rod, butextending about it. i

In practical use when the gate is closed it will be held by the latches D and D and may be opened in either direction, in or out, after manipulating the proper latch to release it. When closing the gate, the latches operate automatically, as will be apparent, the springs '2' being compressed when the latches are forced; to rock on their pivots, so as to move out of the way of the bar K. Ordinarily the weight of the gate is carried by means of the bearings B and L and is held level and plumb by means of the rollers M and N engaging the rod f and serving as hinging devices. WVhen it is desired to elevate the gate to its maximum height, the lever Qshould be moved radially from the position shown in Fig. 1 to the position shown in Fig. 3, resting on the rail G, where it will be held automatically, but may be locked by the button S. The gate may be elevated to an intermediate position by connecting the hook T to the lever Q, as in Fig. 13. When operating the lever Q, the the cable lifts the roller N, and thereby causes the rollers M and N to roll along the rod f. When the gate is lowered and the lever Q returned to its normal position, as in Fig. l the lever is supported in an oblique position by means of the lever Q, resting upon the rail G.

The collar C may be adjusted in its position on the rodf to adjust the length of the cable P. This isa convenient arrangement; but it is obvious that the end of the cable may be attached to the support A or to the post a, if desired, and if the bearings B and L are omitted the cable P will support the gate when lowered. It will be understood that the latches will operate at all times whether the gate is elevated or not, the bar K being of proper length for the purpose. When either latch is operated to permit the gate to close, the opposite latch acts as a stop for the gate to prevent its passing the proper closed position.
