GATE.

SPECIFICATION forming part of Letters Patent No. 776,388, dated November 29, 1904.

Application filed May 25, 1904. Serial No. 209,753- (No model.) i

T 0 CLZZ whom, it nuty concern:

Be it known that I, JosnrH DUNFORD, a citizen of the United States, residing at Canton, in the county of Fillmore and State of Min- 5 nesota, have invented a new and useful Gate,

of which the following is a specification.

This invention relates to gates of the type which swing in a vertical plane from an open to a closed position, and has for its object to IO produce a comparatively simple inexpensive device of this character which may be readily transported from place to place and set up for use, and one in which the pivoting members and operating devices may be readily 5 applied to various gates now in general use.

3 spaced uprights or standards a, secured in place by vertical lag-bolts 5, which extend through the frame 1 and enter from beneath the lower ends of the standards, the latter being further sustained by braces 6 and pro- 35 vided at their upper ends each with a pair of spaced bearing ears or portions 7.

The gate 8, which may be of the usual or any appropriate construction, has detachably connected to its rear end a pair of oppositely- 4 disposed pivoting members 9, having, re-

spectively, outwardly-projecting conical portions 10, terminating at their outer ends in reduced bearing-trunnions 11, which enter bearing-openings 12, formed in suitable bear- 45 ing members or ears 13,disposed, respectively,

upon opposite sides of the gate and detachably connected by screws or otherwise to one of the beams 2, there being produced be- 'tween the conical portions 10 and reduced portions 11 of the pivoting members bearingshoulders 14, which bear against the adjacent inner faces of the members 13 to prevent transverse movement of the gate. The pivoting members 9, which, as before stated, are arranged on opposite sides of the gate, terminate at their inner ends in outstanding flanges 9, arranged in alinement one with the other and perforated at intervals for the reception of through-bolts 10, which pass transversely through the gate and serve as a common means for attaching both of the bearing members thereto, it being observed that by this construction the flanges 9, which present extended bearing surfaces, are mutually braced and strengthened through the medium of the connecting-bolts. The outer ends of the bearing-trunnions 11 are perforated, as at 15, for the reception of the ends of bracing wires or elements 16, the other ends of which latter are connected by a through-bolt 17, extend ed through the gate and serving as a common means for attaching to the latter the pair of braces 16, which are disposed, respectively, upon opposite sides of the gate. It is to be particularly noted that these braces receive and transmit to the pivoting members any transverse strains to which the gate may be subjected by lateral pressure on its outer or forward end and strengthen the pivoting members for adequately withstanding such strains.

Pivotally connected at their lower ends with the gate at a suitable adjacent point to the pivot of the latter is a pair of links 18, arranged, respectively, on opposite sides of the gate and pivotally connected at their upper ends with operating-levers 19, pivoted, respectively, to the standards 1 between the space-bearing portions 7.

In practice, supposing the gate to be closed, downward traction upon the outer end of one of the levers 19 serves through the medium of the corresponding link 18 to swing the gate on its pivot in a vertical plane to open position, when the gate may be returned to closed position in a similar manner by downward movement of the outer end of one of the levers. During the opening and closing of the gate the latter will travel smoothly and evenly, owing to the shoulders 14 bearing against the adjacent faces of the members 13 and to the outer ends of the pivoting members 9 being connected by the braces 16 with the gate. Furthermore, it is obvious that the supporting-frame 1 may be readily transported from place to place and set up at any desired point and that owing to the pivoting devices and gate-operating mechanism being detachably connected with and in no wise affected in operation by the construction of the gate they may be readily applied to many of the various types of gates now in general use.

From the foregoing it will be seen that a simple inexpensive device admirably adapted for the attainment of the ends in view is pro duced, it being understood, however, that minor changes in the details of construction herein set forth may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed is 1. The combination with a support, of bearing members carried thereby, a gate, pivoting members carried by the gate and projecting therefrom for engagement with the bearing members, and braces connected with the gate and engaged with the outer ends of the pivoting members at points beyond the outer faces of the bearing members.

2. The combination with a support, of bearing members carried thereby, a gate, pivoting members carried by the gate and projecting from the latter for engagement with the bearing members, the pivoting members being perforated adjacent to their outer ends at points beyond the outer faces of the bearing members, and braces engaging the perfora tions and connected with the gate.

3. The combination with a support, of hearing members carried thereby, a gate, pivoting members arranged upon opposite sides of the gate and projecting therefrom for engagement with the bearing members, said pivoting members terminating at their inner ends in oppositely-disposed flanges, and throughbolts extended through the gate and flanges and serving as a common means for attaching the pivoting members to the gate.

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

JOSEPH DUN FORD.
