SPECIFICATION forming part of Letters Patent No. 652,018, dated June 19, 1900. Application filed February 15 1200. Serial No. 5,275. (No model.)

T0 at whom it may concern:

Be it known that I, J OHN CHARLES DUNER, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented a certain new and Im' proved Gate or Door, of which the following, taken in connection with the accompanying drawings, is a specification.

-door--such as is used, for example, on elevated trains-considerable room is required for the operation of the door, and if passengers are standing close together and near the door, upon the platform, it is frequently nec-' together, one of the parts being hinged or pivotally mounted upon the door frame or jamb and the other provided with a projection or roller arranged to engage a suitable guideway or slot, which may be either above or below the door, or both, so placed and constructedthat when the entire door swings upon its main hinge the several parts of the door will swing upon the hinges by which they are pivoted to each other into position to close the door-opening on closing movementof the operating means and into position to leave the opening free and clear on opening movement of the operating means, the path of movement of the several parts of the door being within a confined or limited space, as will be hereinafter more particularly described, so as to interfere-as little as possible with any person or persons who may be standing adjacent to the door while it is being manipulated.

The operating means which I prefer to employ in connection with my present invention is generically the same as that forming the subject-matter of a pending application filed by me April 29, 1899, Serial No. 714,950, but specifically embodies certain improvements, which will be hereinafter more fully described.

Referring now to the accompanying drawings, it will be seen that in Figure 1 thereof I have shown a plan section illustrating my improved type of door in open position, in Fig. 2 the door in closed position, in Fig. 3 a side elevation designed to illustrate more clearly the operating means and the improvements thereon, in Fig. 4 a sectional view, on an enlarged scale, of the projection or roller upon the edge of the door, and in Fig. 5 a plan view of the said device.

To a frame or jamb 1 is pivotally secured a door comprising a plurality of parts,as 2 and 3, which parts are pivotally secured together, as at 4, and provided with operating means connected at 5 for opening and closing the door, the said operating means comprising, essentially, a toggle-lever 6, a spring and check device 7, a hand-lever 8, connections 9, and guide-bracket 10, all arranged and operatingsubstantially as shown in the prior application hereinabove referred to.

Upon the part 2 of the door I provide a staple or eye-bracket 11, designed when the door is in an open position to engage a hook 12,

which is pivotally mounted in a bracket 13, attached to the door-frame. To the hook 12 is secured a'rod 14, passing through a guidebracket 15,which forms an abutment, against which the spring 16 acts in a direction to hold the hook or catch 12 in engaging position.

The other end of the rod 14 is formed into a loop 17, which rests above the guide-bracket 10 and throughwhich projects the lower end of a sublever 18, which is pivoted to the handlever at 19 in position to be engaged by the will cause the part 3v to draw away from the said guide having a portion of its length inpost or jam-b 23 and be, as itwere, retracted clinedor ofiset. substantially as, shown at 25, toward the center-of. motion of the part' 2, the and" means whereby the said parts are guided part 2 meanwhile swingingabout its pivot on in opening and closing movement by the said the are 24, the parts of the door when fully guide, substantially as described. 40 opened occupying the position clearly shown 2.
