"boos-HANGER;

spncrrrchrron forming part of nsiasuea Letters Patent No. 12.181, dated December 8, 1903: Original No. 686,774, dated November 19, 1801. Application for reissue filed June 26, 1903. Serial No. 163,198-

To all whom it may concern:

Be it known that I, WILLIAM B. SMITH, a citizen of the United States, residing at War rensburg, in the'con'nty of Johnson and State of Missouri, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specification.

. My invention relates to hangers'for sliding doors for freight-cars barns, and other structures, and is an improvement upon the doorhanger shown and described in my Letters Patent No. 665,036, for which application was filed November 27, 1899, Serial No. 738,389.

' Themain objects of my, invention are to provide an improved form of track and supports therefor together with suitable hangers running thereon; to provide a form of such track whi'ch can be made strong, eflicient,

. door' by means of the d evic and comparatively light at a. comparatively smallexpense, and which may be conven-' ient'ly fitted, cut, and secured for any desired lengths; to provide for readily securing such track by any desired n u-mber ofsupports along a given length of the track without inter fering with the action of the hangers, and to provide an improved hanger ot'isuch form as to permit the ready assembling of the wheel and hanger without machine-work or riveting and to avoid derailment or lateral dis placement of such wheel and hanger when same are mounted on the ire r.

In the drawings, Figure a railway-car to which an":

,view of a hanger, a portion of the doozy the track, track-support, and. the manner in which' the latter is attached to the car. Fig. 3 is a detail view in perspective of an intermediate portion of the track. Fig. 4 is a perspective view of one of the intermediate track-supports. Fig. 5 is a perspective view in detail of one end of the track, Fig. tiisa perspective view in detail of one of theend supports for the track. Fig. 7 is an inside or back view of one of my improved hangers, and Fig. 8 is a like view of a'modified form of hanger.

.Referring to the drawings, (1 represents the body of an ordinary freight-car, to whichare attached by means'of bolts .or screws end brackets b b and intermediate brackets c 0.

each is provided with a flat plate, as shown, having a stud, Figs. 5 and 6, adapted to be inserted within a bore in the side of the 03.1. An opening (not shown i'nFigs. 4 and 6) is also provided in the brackets band a for the insertion of a bolt, as indicated in Figs. 1 and. 2. The brackets are each provided with a horizontal arm 6. Upon the outer end of the bracket b is formed acylind'rical portion fol. a diameter corresponding to the inner diame ter of the tubular track g. In each end of said tubular track informed a slot h, Figs. 2

of the end hracketyjthe'two'endbrackets being inserted from opposite directions. Iutep mediate between the ends at predetermined distances from each other,according to the length of the track, are formed slotst', Fig. 3, for engagement with the intermediate brackets 0, each of which latter is provided with a bent portion j, the curve of which conforms to the interior curve of the tube.

It is obvious that when the brackets are as described, and in turn secured to the' 'i le of the car or other structure the track will be firmly and: rigidly supported thereby.

I Rigidlyatached to the top of the door k by meansof bolts Z are hangers, each of which consists of a flat cast-metal plate m, having bores therein for the reception of said bolts and extended upwardly above the top of the door. Flanges n o are formed uporgthe plate in at right angles thereto and integral therewith, upon theinner ends of which are formed upwardand downward vertical extensions pg, respectively,which are parallel with the main plate m, the inner, faces thereof being flush with the inner face of the door. Within (shown in FigQI and indicatedin dotted lines in Fig. 7) for the reception of the axless s of The axles s, which arepreferably made-from wrought iron or steel, are cast within the wheels, both of which latter are peripherally grooved, as shown, to conform to the cylin The brackets are. formed from cast metal andand 5, which is adapted to receive the part 6.

inserted within the slots of the tubular track,

the outer plate m is formed a vertical slot 7" wheels or rollers i it, one of which is placed above and the-other, below-the track, as shown.

. Notches :r. q are also formed in said extensions to serve as bearings for the axles s. v The lower rollers 14 are placed at a suflicient distance below the track to leavea free space between the twoand serve a double pu rpose-viz.,to prevent friction and binding upon the track when the door is pushed from the bottom or when the oar-body sags, as well as to secure it atall times tothe track, the flangesof the wheels preventing lateral movement.

In utilizing my improved device I first secure the track in position as shown in 'Fig.

1, after which the. wheels are placed in their soective hearings in thehangers, the upper being temporarily held in place by hand This may be done either before or after the door is bolted to the hangers. p

It will be seen from the foregoing that the door is free to roll from end to end of the track without obstruction, none of the brackcts forming. any impediment thereto. .fIhis is ah important advantage and permits the track to be shortened several inches, inasmuch as no allowance need .be made for the width of eitherthe'bracketsor hangers, as is usually necessary to do with 'other forms 0t tracks and hangers. The tubular form of the track g, with its narrow longitudinal slotsin the rear, formsalight and strong structure which is not liable tobuckle and which can be conveniently attached and supported by hangers such as shown. I

Any suitable stop-as z, for exam pie-may be formed upon the side of the car to prevent thedoor from rolling olf the end of the track. h

It is obvious that the rollers in may be contrally bored and that the axles may be inserted loosely therein and through suitable bores in'the hanger-plates, in which case the cut-away portions 1 'w may be'dispensed with, as shown in Fl". 8; butl prefer the construction first described, in thatit permits the more ready assembling of the parts.

Having thus described my invention, what I claim, and desire to secure by Letters Patbut, is V.
