PETER SCHNEIDER, OF OS'WEGO, NEW YORK.

CAR-DOOR HANG-ER.

Application filed January 22, 1917.

To all whom it may concern:

Be it known that I, Pnrnn SCHNEIDER, a citizen of the United States of America, and resident of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Car-Door Hangers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact descriptlon.

This invention relates to certain improvements in car door hangers, as applied more particularly to the sliding doors of freight cars.

The main object is to provide a more secure and, therefore, safer method of mounting the door in such manner that it may be moved easily back and forth without liability of bindin Other objects and uses relating to specific parts of the hanger will be brought out in the following description.

In the drawings- Figure 1 is a side elevation of a freight car showing my improved means for supporting the sliding door.

Fig. 2 is an enlarged transverse vertical sectional view taken on line 22, Fig. 1.

In order that my invention may be clearly understood, I have shown a freight car l having an opening 2 in one or both sides and a sliding door -3 for closing the opening.

- Suitable guide rails 4.- and 5 are secured at their ends to the side of the car in parallelism and in spaced relation one above the other in a horizontal plane above the door epening 2, said rails extending from apoint near one side of the opening some distance beyond the opposite side of said opening approximately twice the length of the width of the door so as to allow the latter to be opened. a. sufficient distance to clear the opening 2 and also to cover said opening when closed.

The guide rail 4 is preferably made in the form of an angle iron having a channel of sufficient width to receive the upper edge of the door and arranged with its vertical flange overlapping upon the outer face of said door to hold the latter closed against outward displacement and still leaving sufficient clearance to prevent binding.

A pair of metal hangers 6 are rigidly Specification of Letters Patent.

Serial No. 143,693.

secured at their lower ends to the outer face of the door 3 in spaced relation longitudinally of said door and extending upwardly across the outer face of the guide rails al and --5 and over the tops of the same where they are returned downi *ardly adjacent the body of the car, leaving an intervening space between the front and rear sides of the upper portions of the hangers for the reception ofseparate pairs of rollers -7 and 8 which are journaled upon a suitable supporting pin --9 connecting the outer and inner sides of the upper portions of their respective hangers.

The rollers 7 are movable along and upon the upper face of the lower rail eland are of somewhat greater diameter than the rollers 8 which are movable along and against the under side of the upper rail 5, as shown more clearly in Fig. 2.

This upper rail 5 is, therefore, disposed at the outside of the upper portion of the rollers -7 in close proximity thereto and serves not only to additionally hold the door against outward displacement from the car, but also to prevent forward or rearward swinging or binding of the door; which enables the latter to be moved back and forth more easilyand with less liability of displacement than would be possible with the use of a single guide rail, as l, and one set of rollers, as 7.

The rollers and -8- of each pair turn independently of each other so as to reduce the friction incidental to the sliding of the door to a minimum.

The guide rail 5 renders the fastening of the door doubly safe against outward swinging movement or accidental displacement for the reason that if either rail should be loosened or give way entirely, the other rail would still retain the door in place.

The installation of this extra rail 5 is comparatively inexpensive and may be used in conjunction with many of the ordinary guide rails now in common use by simply substituting these hangers for those previously used.

VJ hat I claim is:

In combination with a car having an opening and a sliding door for the opening, parallel lengthwise rails secured to the car one above the other above the opening,

hangers secured to the car; separate pairs of coaxial rollers journaled on their respective hangers, those oiea'ch paii" of unie qual diameterand coaxial, the larger rolle i's being engaged with the upper face of the'lower rail and with the inner face of the upper 'ail to assist in holding the door against outward displacement, the smaller mner'b'eing engaged with the lower face of the up per rail at the outside of the larger roller.

Inwit'ness wl'i'ereof I have hereunto set niyhand this 11th day of January, 1917.
