SPECIFICATION forming part of Letters Patent No. 651,080, dated .I une 5, 1900.A

Application tiled February 9, 1899. Serial No. 705,133. (No model.)

To all whom it' may concern:

Be it known that we, FRANCIS O. LIsTnR, residing at Altoona, in the county of Blair and State of Pennsylvania, and PHILIP L. RAYMOND, residing at Bordentown, in the county of Burlington and State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in or Relating to Car-Doors, of which the following is a specification, with accompanying drawings.

Themain object of the invention is to provide an improved durable, simple, and economical trolley system for the door, by means of which it can be easily and quickly opened.

The invention will be understood by the following specification of its preferred embodiment, and the novel and characteristic features will be pointed out in the claims.

Figure 1 shows, partly in section, a portion of a freight-car and door provided with our improvement. Fig. 2 is an end View showing the door-frame, dac., the door being in closed position; and Fig. 3 is a plan view of the rail and trolleys.

In practicing our invention we prefer to have the door close in flush with the outside of the car or with the door-frame. The door is provided with a trolley bracket or hanger B at the forward end of the door and a swiveled trolley near the other end, both of which run on the curved rail A, which is channeled, so as to provide alow outer ange and a high inner flange. The high inner iiange forms a fiat guiding-face throughout the length of the rail, lying against the car-door frame .at the forward end (or at the right hand of the iigure) and thence running out from the cardoor frame or car-wall and standing out in front of it, as shown in plan in Fig. 3. The swiveled trolley is secured by link K to the hinge-bracket C, which is screwed to the door. The joint between the link and the bracket does not,however,support,as usual,t he weight ofthedoor. Onthecontrary,weprovidearigid slotted guide-arm or projection, preferably pressed or forged in one piece with the bracket C, as shown, and extending transversely to the link K, so as to rest directly upon the link, and so carry the weight of the door. The pivoted fastenings at the ends of the link are thus relieved absolutely of all twisting strain. The axis of the pivotal joint J should be in a vertical line passing through the point where the trolley rests on the rail A, and the free movement of the link in the slotted guide on the bracket C. The friction between this guide and the link, though slight, is advantageous, as it is sufficient to prevent any accidental movement of the door by gravity when the car is standing and the door unlocked.

Beneath, the door may be guided, as usual, by a rail G and guide-shoe F.

At His shown an iron provided with a projecting stud or bolt which enters a coperating recess in the door-frame to hold the door laterally when closed. The other end of the door may be held in closed position iush with the car or door frame by any desired means.

There is shown for this purpose a pocketplate E and button-lock lever D, with a sealing-staple L; but this combination is a separate invention.

At I is shown a stop for the' door when opened.

In operatin g our invention to open the door it is only necessary to draw the door, or rather one end of it, outward and then push itopen, while to close it this operation is reversed.

Ve claim as the novel and characteristic features of our invention the following:

1. In combination,a hinge-bracket provided with a transverse rigid guide-arm, a link hinged to said bracket and normally pressing upward against said guide-arm, and a slide or trolley carried on the free end of said link, substantially as and for the purposes set forth.

2. In combination in a hanger for a sliding car-door, a hinge-bracket provided with a transverse rigid guide, a link hinged at'one end to the bracket and normally pressing upward against said guide to support the door, and means for movably supporting the other end of said link, and thereby supporting said door, substantially as and for the purposes set forth.

IOO

3. A hanger for a oar-door having a hingebraeket provided with a transversely-slotted project-ion or guide-arm, a link pivoted to the bracket and movable in said slot, and a trolley carrying the said link, substantially as and for the purposes set forth.

4. In a hanger mechanism for a sliding door, a link, means for pivotally securing the link to the door, a transverse guide resting normally on the said link and sustaining the Weight of the door, and a trolley pivoted to 4 the outer end of the said link, whereby the said link acts as a short movable lever pressing downward at both pivotal connections, and pressing upward against the said guide to support the door, substantially as and for the purposes set forth.

In testimony that We Claim the foregoing as our invention We have signed our names, in' the presence of the subscribing Witnesses, this l1th day of February, 1899. V
