GATE.

SPECIFICATION forming part of Letters Patent No. 446,325, dated February 10, 1891.

7 Application filed April 2, 1890. Serial No. 346,255. (No model.)

T0 at whom it may concern.-

Be it known that I, FRANCIS 0. CASH, of Lynn, in the count-y of Essex and State of Massachusetts, have invented certain new and useful Improvements in Railway-Gates, of which the following is a specification.

This invention relates to railway-gates and it has for its object the provision of a simple and at the same time an effective gate which may be easily raised and lowered without liability of interfering with electric or other wires strung along or other structures upon the roadway or street across which the gate is to be thrown, or of being lowered without warning, thus endangering the lives of persons and horses happening to be in the way.

Ofthe accompanying drawings, forming a part of this specification, Figure 1 presents a top plan view of a railway-gate embodying my invention, showing the gate lowered. Fig. 2 presents a side elevation of the same in a similar position. Fig. 3 presents a side elevation showing the gate raised, leaving the road open and clear. Fig. 4 presents a side elevation showing the gate half raised.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents a standard or post of the usual or any suitable form, provided with the shaft 1), on which the inner section of the gate is pivoted, said shaft being preferably situated near the top of the standard.

1) represents the inner or pivoted section of the gate, consisting of two arms, which are pivoted or fulcrumed on the shaft 1), which is journaled in the standard a. Said section b has at one end a back balance 0. At the same end and from each arm of said section rise the ears (Z, which hold the stop-bar e, which prevents the gate from being swung too far back when being raised. At the other end of the inner section Z) the two arms or principal beams thereof are joined by a crosspiece a", to which is attached the hinge which Y connects the outer to the inner or pivoted section.

f represents the outer section of the gate, which is hinged at g to the pivoted sect-ionb. Near the outer end of said outer section f one end of a chain h is fastened, the other end of said chain being made fastto the top of the post or standard a. The chain h is of such length that when the arm or gate is extended, as shown in Figs. 1 and 2, it will be tightened and will support the outersection of said gate,

and when the gate is raised it will be of sufficient length to allow the outer section to fall gradually by its own weight until thepivoted arm I) is fully raised, when it will lie close against the pivoted section b, as shown in Fig. 3.

It will be seen that the chain will perform the functions above referred to by having it arranged so that the end which is attached to the post or standard is above the point at which the inner section b is pivoted. It will also be seen that when the gate is being lowered the chain running over the ends of the sections 1) f at Q will extend the outer section until the gateis fully lowered, when it will be in line with and constitute a prolongation of the pivoted section b. It will be further observed that by this action of the hinged gate above described said gate is not liable to fall upon horses, teams, or foot-passengers, noris it liable, owing to its small total height to interfere with or damage electric wires strung along the road which is crossed by the gate. This latter feature constitutes a great advantage of my improved gate over the old forms of railway-gates.

A crank may be attached to the shaft 2) by which the gate may be raised and lowered by the usual mechanism.

I am aware that it is old to provide a gate with a pivoted extension having a flexible connection to the main standard or post, so as to be projected from avertical to a horizontal plane as the gate descends and to be folded in against the main section ofthegate as it ascends, and I desire it to be understood that I do not claim so broadly as to include such a construction. It has been found in practice, however, that where, as in the case referred to, the flexible connection extends from the standard to the inner end only of the extension, great power is required to lift the arm to a horizontal plane; and, further, that where such an extension-arm is simply pivoted to the main section no stability is given the arm, and it is easily broken by 1at eral pressure on account of its lack of bracing in any direction. In my improved construction I have aimed to diminish the power required to extend the arm by running the operating connection to the outer end of the extension, thus aiding also to brace or truss the whole length, and by hinging the extension on its lower edge to the end of the main arm of the gate the ends of the two parts abut when the gate is downward and form a brace against lateral strain, and with the operating connection which sustains the gate longitudinally the extension is thoroughly braced and held almost as rigid as if it were integral with the main section of the gate.-

It will be understood that instead of the chain a rope or wire may be used as the operating connection.

\Vhat I claim is 1. A railway-gate consisting of a main section pivoted on a standard or post, an extension-arm hinged to the end of the main section, and an operating-connection extending between the standard or post and the outer end of the extension-arm, whereby the power tion pivoted in a standard or post, an exten sion-arm hinged at the lower edge of its inner end to the lower edge of theouter end of the main section with ends abutting when the gate is extended, and an operating-connection extending between the standard and the outer end of the extension-arm, the abutting faces of the two sections above the hinge sustaining the sections against lateral strain, while the operating connection extending to the outer end of the arm sustains said arm longitudinally, substantially as described.

In testimony whereof I have signed my name to this specification, inthe presence of two subscribing witnesses, this 27th day of March, A. D. 1890.

FRANCIS 0. CASH.
