COLLAPSIBLE'iGATE.

SPECIFICATION forming part of Letters Patent No. 730,036, dated June 2, 1903.

Application filed August 15, 1902- Serial No. 119,703. (No model.) i

To all whom it may concern;

Be it known that I, CHARLES MEYER, a citizen of the United States, residing atNew York, in the county of New York and State of New York,have invented certain new and useful Improvements in Collapsible Gates, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved collapsible gate particularly designed for use on elevated and other cars, but which may be used wherever gates of this class are desired, a further object'being to provide agate of the class specified which is simple in con struction and operation and provided with convenient and effective devices for opening and closing the gate and for holding it both in the open and closed position.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in whichthe separate parts of my improvement are designated by suitable reference characters in each of the views,'and in which Figure 1 is an inside perspective View of my improved gate and the support thereof and showing the gate folded or collapsed; Fig. 2, a back view of the support of the gate and the parts connected therewith; Fig. 3, a view similar to Fig. 1, showing the gate extended; Fig. 4, an outside View of the gate folded or collapsed; Fig.5, a section on the line 5 5 of Fig. 2, and Fig. 6 a section on the line 6 6 of Fig. 3.

In the practice of my invention I provide a suitable support, which may consist of theend of acar or of a stationary frame or of a panel of a fence with which a gate is to be connected, but which, as shown in the drawings, consists of a frame composed of vertical members a, horizontal members 0 and diagonally arranged members a The gate proper consists of end members Z) and c and lazy-tong levers d, and the end member I) is composed of two parallel bars b secured to one of. the supports by angle-pieces b or in any desired manner, and two of the angle pieces in the form of construction shown support a supplemental vertically-arranged strip orbar bfiwhich is intended to give strength to and protect the movable parts of I the gate, especially when the latter is folded together.

Two sets of vthe lazy-tong levers d are employed in the usual manner, and one of said lazy-ton g levers at each end of the gate is piv- 'oted to the top of the end member at 01 and two of said lazy-tong levers are pivotally connected, as shown at d in Fig. 6, with slides d, which move on the side bars (1 of the end member I) and the side bars 0 of the end member 0. v

Mounted horizontally of the support on the gate is a shaft 9, the end of which adjacent to the gate is provided with a gear-wheel e ,which operates in connection with a larger gearwheel e mounted on the support adjacent to the gate and in a vertical plane parallel with the gate, and the wheel 6 is provided with a crank-link a which is connected at 6 with one of the lazy-tong levers d of the gate.

One end of the shaft 6 is supported in a tubular bearing f, secured to or in the main support of the gate, and connected with this tubular bearing or otherwise suitably supported is a beveled gear-wheel g, provided with a crank-pin g and the beveled gearwh'eel g operates in connection with a smaller beveled gear-wheel g secured to the shaft e.

In the operation of extending the gate all that is necessary is to turn the wheel g to the right by means of the crank-pin f and this operation turns the shaft 6, the wheel 6 and the wheel (2 and the crank-link e extends the gate, as shown in Fig. 3. In order to fold H or collapse the gate, the wheel g is turned in the opposite direction or to the left and the gate is folded or collapsed, as shown in Fig. 4. The position of the connection of the crank-link e with the wheel 6 is such that it will hold the gate either in the open or closed position, and the gate cannot be opened or closed without turning the wheel g.

The entire device is simple in construction and operation and is much more convenient when used as a gate for elevated cars than the fact that the gate does not have to swing on hinges, and people may stand on the platform close up to the gate without any inconvenience or without interfering with the operation of the gate, and when used for this purpose the support of the gate would be at the apparatus now employed by reason of the end of the platform, as at the present, and not at the end of the car, and the wheels 9 would be operated by the guard in the same manner as the ordinary crank-levers are now operated for opening and closing gates of elevated cars.

It will be apparent that my improvement may be used wherever collapsible gates may be required, and I rese 've the right to make all such alterations in and modifications of the construction described as fairly come within the scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination with a support of a coliapsible gate consisting of end members and lazy-tong levers, one of the end members being rigidly secured to the support and the lower portions of the lazy-tong levers at each end of the gate being slidably connected with the end members, a shaft mounted on the sup port at right angles to the gate, and provided with a gear-wheel, another gear-wheel m0unted on the support and operating in connection with the first-named gear-wheel, a crank-link connected with the last named gear -wheel near one side thereof and with one of the lazyton g levers of the gate and adapted to open and close the gate and to lock it in either position, and means for operating said shaft consisting of a beveled gear-wheel mounted on the support,a beveled gear-wheel connected with said shaft and a crank-pin connected with the firstnamed gear-wheel, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 13th day of August, 1902.
