CONNECTICUT, ASSIGNOR, BY MESNE ASSIGNMENTSTO THE NEW HAVEN ELEVATOR GUARD COMPANY, OF

SAME PLACE.

ELEVATOR GATE AND DOOR.

SPECIFICATION forming part of Letters Patent No. 523,639, dated July 24, 1894.

Application filed April 2, 1894.

To all whom it may concern Be it known that I, CHARLES E. JONES, of

New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Elevator Gates and Doors;

and I do hereby declare the following, when taken In connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact descript1on of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a View in perspective of a pair of elevator-well doors provided with one form which gates constructed in accordance with my invention may assume; Fig. 2, a view partly in vertical section and partly in front elevation showing the doors and gates in their open positions.

My invention relates to an improvement in guards for elevators, the object being to render the same doubly safe by a very simple and nexpensive device.

With these ends in view, my invention conslsts 1n the combination with a pair of elevator-well doors arranged in the plane of a floor, of two gates having their outer ends pivotally connected with fixed supports, and their inner ends pivotally connected with the respective doors so as to open and close with the same.

My invention further consists in certain details of construction as will be hereinafter descr1bed and pointed out in the claims.

As herein shown the elevator-well doors A- A are of ordinary construction, and automatically opened and closed by any suitable mechanism, devices for this purpose being well known. For illustration, I have shown a lever mechanism consisting of a rotatable head 12, a bowed operating-arm a rigidly con-. nected atits lower end with the saidhcad,

and extending upward therefrom, a straight arm at rigidly connected at its upper end with the said head, and extending downward therefrom, a brace c uniting the outer ends of the arms a and d, anda rod or link a connecting the lower ends of the brace c, and the armd, with the adjacent door A. The other door is 5 Perated by lever mechanism, duplicating scope of my invention.

that described. When the elevator car descends, its lower end strikes and depresses the upper ends of the operating-arms, and thus opens the doors, which close by gravity, following the car in its descent. When the car ascends its upper end lifts and opens the doors. Two links or rods B B respectively pivoted at their lower ends to the outer ends and at the inner corners of'the doors, are respectively pivoted at their upperends to the inner ends oftwo normally horizontal gates C C, the outer ends whereof are pivoted to the upper ends of stationary posts D D, secured to the floor E to which the doors are attached, located on opposite sides of the elevator-well F so as to be quite out of the way, and provided with bearings G G extending horizontally from their upper ends to receive the studs H H on which the outer ends of the gates are hinged.

Underthe described construction, the gates C C'will assume the horizontal positions in which they are shown by Fig. 1 of'the drawin gs when the doors are closed, and be thrown upward and outward as shown by Fig. 2 of the drawings when the doors are automatically opened. It will thus be seen that when the doors are closed, the gates are in position to prevent any one from walking in upon the doors and thus exposing themselves to accident by the Sudden opening of the same preparatory to the approach of the elevator car from above or below the floor provided with the gates.

It is not essential that the gates have the particular construction shown and described, and I would therefore have it understood that I do not limit myself to the particular construction specified herein, but hold myself at liberty to make such changes and alterations therein as fairly fall within the spirit and Having fully described my invention,

I claim as new, and desire to secure by Letters Patent, is-- 1. The combination witha pair of elevator well doors, of two normally horizontal gates located adjacent to the said doors,supported at their outer ends independently thereof, and respectively connected at their inner ends therewith, substantially as described, and whereby the gates partake of the opening and closing movement of the doors.

2. The combination with a pair of automatic elevator-well doors, of two normally horizontal gates located adjacent thereto, and links or rods connecting the gates with the doors so as to open and close with the same, substantially as described.

3. The combination with a pair of automatic elevator-well doors, of two gates, supports to which the outer ends of the said gates are pivoted, and links or rods connecting the inner ends of the gates with the respective doors which operate to open and close the gates when the said doors are opened and closed, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CHARLES E. JONES. Witnesses:

JOHN G. CHAPMAN, WILLIAM A. LINCOLN.
