To all 'whom it may cmzccrn:

Be it known that I, Josemi F. Conan, a citizen of the United States, residing in the" city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Car-Door Hangers, of whcli I do declare the following to be a full, clear, and exact description, reference being had to the drawing forming a part of this specification.

The present inne. mn has for its object to provide improved mechanism for suporting and guiding the sliding doors of reight cars, and the invention consists in the features of novelty hereinafter dcscribed, illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure 1 is a view in side elevation showing part of a freight car body equipped with a sliding door provided with my improved door-supporting and guide mechanism. Fig. 2 is an enlarged view in vertical section on line 2-2 of Fig. 1. Fig. 3 isan enlar ed view in vertical section on line 3-3 o? Fig. 1. Fig. 4 is an enlarged detail view in front elevation showing, more particular] one of the roller brackets or. casiiigs an adjacent parts.

A designates the side wall ofa freightcar and B denotes the sliding door thereof. Above the -top of the door B and fastened to the overlianging part of the car wall is'an Vmove? -upwa d extension Fwill force the door in-l ward and thereby cause it to more tightly upper guideplate C that serves to prevent the outward movement of Qthe upper part of the car door B. To the lower edge of the car door 1i is secured a Z-shapcd bar D that extends from front to rear of the door. This Z-bar l) has an upper member extending vertically along the lower portionV of the door B and has a horizontal member extending beneuth the edge of the *door and an inner vertical member extending downwardly and inside the track bar E. In the present form of my invention, this track bar E consists of an an ular guide. This track bar E is supported y brackets F which are arranged at convenient distances a art beneath and along thc path of trave of the door B. Each of the brackets F is preferabl formed as a metal castinghaving its body strengthened by upwardly projecting ribs f and having an inwardly projecting or thickened portion or boss f extending toward and ada ted to bear against the side wall of the carl eneath the floor G thereof.

Each of the brackets F is also formed with an outer vertically extendingwall f2 which I forms, with the body of casting, a channel adapted to receive the lower member of the i ick bai' E. Each of the castings is secured the car body by means of through bolts J and 11, the through bolt 10 passing also through the lower, vertical member of the track bar E and serving to securely hold said track bar in place.

It will be observed that the shape of the casting F is such that the track bar E mav be held :it a sufficient distance' from the Wall of the car body beneath the floor G to enable the Z-bar D to move freely back and forth. It will be seen. also, that the horizontal member of the Z-bar D extends some distance inward beyond the outer edge of the Hoor G that projects through the door opening of the cai', as by this construction better-guarded against ac( i of dust cinders, snow, etc., than if the floor G terminated in line with the vertical member of the Z-bar l). One o1 the brackets F located adjacent the left-hand sid. of the door-opening is formed with an upward extension Fv having a cam-shaped inner face faadapted to contact with the depending inner member `the lower portion of the door-opening is of the Z-bar D, so that as the door B is #o closed position, the cam face of the close the door opening of the car.V Inasmuch :as this upward extension F 'of th'e bracket( `bears against the vertical member of the track bar lil, the outward strain u )on such l vertical extension is resisted by t e track bracket is materially lessened.

I (lo not wish to be understood as claiming in the present application the construetion of the bracket F, as this forms the sub- `bar and the danger ot' breakage of the I ject-matter of a se a-iate application filed by me of even date erewith.

To the lower portion of the door B are secured a series of roller supporting breek- `the castings ll which projects inward from the upper face of the casting, sets within a cutaway space or recess formed 1n the v,lower edge portion of the door B and in the Z-bar D. Vitltin the chambered portion of each of the castings H is mounted a roller K adapted to travel upon the surface of the track bar E. `Each roller K is .mounted upon a pintle that projects outwardly through the chambered portion of the casting and through the front wall .or -diap'hragm lf2 that is formed as an integral part of the casting H. That portion 'of the pintlc-15 that projects through the wall h2 is preferably reduced, as at 16, and through the outer reduced end portion of the pintle is passed a cotter pin 17 that serves to securely hold the pintle in place.

Inasmuch as the chambered portion of each ofV the `castings H extends beneath the door and is approximately equal to the thickness of the door, the casting takes up but very little room and aords a very firm and secure housing for the roller K. It will be understood, of course, that the pintles 15 that support the rollers K will be inserted through the holes in the inner Walls of the castings H and the shouldered outer portion of the p intles Will prevent their being withdrawn from the front,even if the cotter pins should be removed.

The sliding doors of freight cars being subjected to extremely severe strains in use, it is highly important that the door supporting. rollers should be secured in the most edective and stable manner, and inasmuch as.

the castings H are,carried within seats or` cutaway spaces in the lower edge of the door and in the Z-bar D, they will be so firmly held as to guard against all danger Aof displacement under the severe strains without departing from the spirit of the invention and that. features of the invention may be employed without its adoptlon as an. entirety. l

Having thus described my invention, what I claim as new and' desire to secure by Letters Patent isw 1. In mechanism of the character described, the combination with a sliding door and with a track supported beneath said door, of a Z-bar attached to the lower edge of the car door, both said Z-bar and said car door having recesses formed therein, a plurality of casings arranged within said recesses of the car door and Z-bar, and a pluA rality of rollers within said casings and .adapted to travel upon said track.

2. In mechanism of the character dcscribed, the combination with a sliding car -the car door and Z-bar, said casings being provided at their front with flanges, bolts passing through said flanges and through the car door and Z-bar, and a plurality of rollers within said casingsand adapted to travel upon said track.

3. In mechanism oit the character described, the combination with a sliding door and with a track bar supported beneith said door, of a Z-shapcd bar attached to the lower edge of the car door, the inner vertical member 'of said Z-bar depending inside said track, said car door having recesses formed therein at its lower edge, a plurality ot casings arranged within said recesses of the car door,` and 1 plurality of rollers within said casings and adapted to travel upon said track.

4. The combination with a car body ha ving a door opening and a sliding door for said opening, of a track bar located beneath and in proximity to the bottom of said door and secured to and space from the side Wall of the car, a' Z-shaped member having ayhorizontal portion-1' at; the lower edge of the door, an inner vertical flange de: j'
