PERCY IVI. ELLIOTT, OF CHICAGO, ILLINOIS.

CAB-DOOR- MEGHANSM;

Specification of Letters Patent.

Patented Apr. so, 1912.

Applicationled October l1, 1911. Serial No. 654,178.

of which do declare the following to be afull, clear, and eXactdescription, reference being had to the accompanying drawing, forming part of this specification.

Illy present invention lhas for its object to" provide improved means for sustaining the sliding doors of railway freight cars and the invention consists in th'e features of nojety hereinafter described, illustrated in the accompanying drawing and particularly pointed "out in the claim at the end of this specification. 4 l

Figure l is a view in side elevation showing part of a railway car having my invention applied thereto. Fig. 2 is a view in vertical cross-section on line 2 of Fig.v l. Figs. 3 and #l are views in horizontal section on the lines 8 and il, respectively, of Fig. 2. Fig. 5 is a detail view of a modification with' parts in section on the line 5 of 2. Above the doorway or door opening in the side wall A of the cur is arranged a rail bar B that is connected to the side Wall of the car by through-bolts C. The rail B may be descrililed as a T-shapcd bar, in that it has a vertically disposed upper base'fiange b through which the rail is bolted to the ear wall, a lower flange or member serving as a guard flange and a horizontally7 outwardly projecting track flange or member The upper, vertically disposed flange o is preferably formed of considerable height,

so as to enable the througl'rbolt C to be placed at a distance above the track flange b2, and to provide a broad bearing for the rail or track bar against the side of the car, thus much more effectively enabling the rail or track B to sustain the Weight of the car door D and its fittings. As shown, the lower depending guard flange h lies in the plane of the base flange and the track flange 32 projects outwardly from the lower' portion of the base flange.

To the upper portion of the car door D are bolted the suspension brackets F. As shown, cach of these brackets has its upper part formed as a hood or casing a to inclose an anti-friction roller F that rests upon the upper face of Athe track flange b2'. vThe roller is journaled within the casing on an inwardly projecting stud ef of the bracket and is held in place by a bolt or rivet y, Each of the bracketsl is also provided, at a point below the track flange b2 with guiding v Ymeans arranged to engage the under side of s'aid track flange in casev the door is raised slightly and thus insure the more accurate movement of the parts as the door is moved back and forth.

which a small roller F is journaled upon a bolt or rivet f. y, y

Upon the upper edge of the door is mount-- ed aZ-shaped metal bar G that is connected to the door by through Vbolts passing .Preferably, each bracket E is provldedwith va housing e2 Within through the outer flange g of the bar that depends over the outer face of the door.' The inner flange g of the bar G extends upwardly inside of the guard flange Z2 of the rail B and thus' serves to prevent the aceidental disengagement of the door hangers from the track bar. This arrangement also protects the door and the door opening from the weather.

rlhe guide rollers F are slightly spaced from the under side ofthe track [lange b2, but, vin shifting the door, it is frequently lifted andthe rollers F disengaged from the upper face ofthe-track flange. When this occurs the rollers F" will engage the track flange and properly guide the shift of the door and thus prevent binding. If desired, an inwardly projecting guide shoe F2 (see Fig. 5) 'upon the bracket ll may be substituted for the roller F. Preferably, the casing e is provided with outturned or Wedge shaped lower edges for cleaning the upper face of the track flange.

It should noted that vthe applicants improved T-shaped rail which abuts against the side of the carcan be securely bolted to .the ear at points Well'abutting the track flange which sustains the Weight of the door.
