be understood that the construction of each of the hangers 4- is identical and the description of one will suiiice' for all.

The support 5 includes an outwardly cx tendingand upwardly curved goose-neck 7 having provided in its end a recess 8. The end of the goose-neck T terminates short of the base 5 as will beevident from Fig. 3, the obvious purpose of the intervening space being to permit the insertion of the sheave 9 and the assemblage of the supporting elements therefor.

The sheave f) has a semi-circular ball-race 10 which with the coinplenlental ball-race ll of the bearing cone 12 supports a plurality ot' ball-bearings 123. The bearing cone 12 includes a sleeve H which is of such a length as to terminate evenly with the base of an annular recess 15 in the outer surface of the sheave E).

The recess 15 receives the end of the goosetion to the support uttered by the bearings 13. Adjacent shoulders 16 and 17 respectively of the bearing cone 12 and sheave f) are rounded as indicated in Fig. 5 forming an annular groove upon which the ballbearings 13 rest and upon which the weight of the door 1 principally rests.

A lateral channel in communicating with formed by the rounded portions 145 and IT. terminates at the base of the recess 1.3 where a lubricant is delivered thereto from a well 19 in the upper surface of the goose-neck T.

A square bolt 20 is passed through the car door lptllt base 5. of the hanger l and en- A collar 21 positioned upon the bolt 20 forms a spacing member between the head of the bolt and the rear surface of the bearing cone 12. The head of the bolt 20 being seated in a square recess at the back of the car door 1, prevents turning of the bolt and consequently the hearing cone 12 is held rigidly in position. It will also be obsenved that the bearing cone 12 has an additional annular flange 12 which enters a similarly rear surface of the sheave 9.

Tracks 22 and23 are provided for the sup port and guidance of the door 1 and sheaves 9. The tracks 22 and 23 are supported by brackets 21 at the extremities of the car 2. It will. thus be understood that no intermediate supports of any kind are provided for the tracks 22 and 23 thereby ofi'ering no obstruction to the free movement of the door 1 over the surface of the car.

Bracing strips 25 also secured to the brackets 24 and secured at intermediate points to the respective tracks 22 and 23, impart suflicient rigidity to the tracks to prevent buckling thereof. It will be observed that the bracing strips '25 attached to the upper tracks 22 have right angularly turned flanges :25" upon which shields 26 are secured. These shields 26 extend downwardly over the hangers 4 and effectively cover the h angers so that foreign elements such as dust and moisture may not collect upon the movable parts of the hanger.

An abutment strip 27 disposed in such a manner as to receive the adjacent edge of the door 1 is arranged at one side of the doorway 3 as shown in Fig. 1. A hasp 28 and staple 29 together with the lock 30 form the securing means for the door -1. An arcuate support 31 receives the hasp when in its freed position and prevents the hasp from dangling upon its fulcrum when the door is open.

\Vhile the operation of the door is thought to be obvious, a rsum thereof is thought to boot advantage. In assembling the hanger 4. the sheave 9 is applied to the end of the goose neck 7 so that it rests in the recess 15. The bearing cone 12 having the ball-bearings 13 is then moved into position when upon applying the, bolt 20 and the collar 21, the hanger may be secured upon the car door.

,The engagement of the door 1 with the side of the car will effectively prevent the bolt 20 from moving outwardly out of engagement with the recess 8 in the goose-neck 7.

The lubricant well 19 will feedthe lubricant continuously to the channel 18 and in turn to the ball-bearings 13. The brace strips 25 prevent the sagging of the tracks 22 and 23 and an easy movement of the door is obtained requiring little physical effort to open and close the door-way 3.

W'hile the construction and arrangement of the device is that of a generally preferred form, obviously modifications and changes may be made without departing from the spirit of the invention or the scope of the claims.

I claim 1. In a device of the class described, the combination of a base member, an outwardly extending upwardly curved goose-neck having an inwardly extending upper end, said goose-neck being formed upon said base member and having its upper end spaced from said base member said base .memher having an opening l-Il alinement- With the end of said goose-neck, a bolt passing through the opening in said base memher and engaging the end of said goose-neck, a collar carried upon said bolt, a core carried by said bolt and being held againsbshifting in one direction by said collar, a sheave rotatably mounted upon the end of said neck and upon said core, whereby the sheave will be held against displacement.

2. In a device of the class described, the combination of a base member, an outwardly extending upwardly curved goose-neck having an inwardly extending upper end. said goose-neck being formed upon said base member and having its upper end spaced from said base member, said base member having an opening in alinement with the spaced end of said goose-neck, a squared bolt passing through the opening in said base member and engaging the end of said goose-neck. a core positioned upon said squared bolt and fitting adjacent the end of said goose-neck, a collar carried upon said bolt and bearing upon said core for holding the core against shifting. a sheave rotatably mounted upon said core and the end of said goose-neck, a1 (1 anti-friction means interposed betwcel said core and said sheave.

3. In a device of the class described, the combination of a base member, a goose-neck formed upon said base member, a core having a sleeve bearing upon said goose-neck, me'ans for supporting said core. said gooseneck having a well in the top portion thereof. said sleeve having a channel communicating with said well, a sheave rotatably mounted upon said core and said goose-neck, whereby lubricant may be placed within the well to pass through said channel and lubricate the inner portions of said sheave,

In testimony whereof I aliix my signature in presence of two witnesses.
