Patented Feb. 26, 1895.
THOMAS C. ALLEN, OF DALLAS, TEXAS.
CAR-DOOR.
SPECIFICATION forming part of Letters Patent No. 534,940, dated February 26, 1895. Application filed April 25, 1894;- Serial No. 508,972. (No model.)
To all whom it may concern:
Be it known that I, THOMAS C. ALLEN, of
Dallas, in the county of Dallas and State of Texas,have invented certain new and useful Improvements in CarDoors; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.
This invention relates to certain improvements in freight car doors and supporting means therefor.
The object of the invention is to provide an improved freight car door so supported that it will not be shaken or jarred off and can be easily opened and closed at all times no matter how heavily loaded the car may be.
The invention consists in certain novel features of construction and in combination of parts more fully and particularly pointed outhereinafter.
Referring to the accompanying drawings: Figure 1, is a side elevation of the improved freight car door showing a portion of the car. Fig. 2, is a vertical sectional view through a portion of the car and through the door taken on the line X X, Fig. 1.
In the drawings the reference letter a, indicates a freight car provided with the sliding door I), to close the opening into the car. This door is carried by hangers a. Each hanger consists of a frame secured to the door and extending upwardly from the same. This frame at its upper end is provided with the two parallel horizontal bars (55, located a distance apart and preferably formed integral with the upright portion of the hanger frame. On their under sides these bars can be provided with elongated ways of suitable length having stops at the ends. A supporting wheel 6, provided with the end studs or 1 d pintles f, ex-
en ing beneath said bars and into said ways so that the door is hung from the pintles of said wheels and the wheels freely travel between the said bars of the hanger frames. Each wheel has two bearing surfaces or treads separated by the central groove or depression.
is located between said bars and is Above the opening in the car the track g, is
rigidly and horizontally secured. This track extends outwardly and horizontally and is formed of any strong, suitable material and is provided with the two tracks or ways to respectively, receive the two treads of each wheel of the hanger and said two tracks are extending between the two treads of each hanger wheel. I The guard track prevents the hanger wheels from jumping from the supporting track. The guard track of the sup porting track can be formed integral in cross section if desired,or they can be formed separately and separately secured if desired.
It should be noted that the supportingtrack extends outwardly and directly over the upper edge of the car door, and guides said door, the hangers having the two bars resting on the axles or studs of the supporting wheels directly over the two ways of the supporting track distributing the weight equally on said supporting track.
The outer face of the lower portion of the door is provided with a suitable number of casings j, provided with the horizontal pulleys is, projecting through the outer faces of the casings and arranged to engage the inner surface of the rail Z, located outside of the door and rigidly and suitably secured to the car beneath the door. Said casings are preferably formed angular with a portion extending beneath the edge of the door and a portion located on the outer face of the door and the rollers are journaled in openings in said casings so as to project a short distance beyond the casing. This arrangement enables the door to slide easily no matter how much weight there may be located within the car pressing outwardly against the door as often happens in heavily loaded freight cars by reason of the shifting of the load when the cars are in motion.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
A freight car having the horizontal track composed of the single inclosing track iron provided with the upper depending flange, the lower treads having the central vertical flange, the car door having its upper edge traveling along the under edge of said track iron, the door hangers having the double wheels in said track iron straddling said flanges, the rigid guard rail arranged at the outer face of the lower side of the door, the angle casings secured in the lower edge of the door and provided with the horizontal rollers to travel against said guard rail, substantially as described.
In testimony that I claim the foregoing as my own I affix my signature-in presence of two witnesses.
