FREDERICK SEABERG, OF CHICAGO, ILLINOIS, ASSIGNOB. TO NATIONAL DUMP CAR y COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF MAINE.
DOOR-OPERATING MECHANISM FOR- RAILWAY-CARS.
messes.
Be it known that I, FREDERICK Snnnns, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Door Operating Mechanism for Railway-Cars, of which the following is a description, reference being had to the accompanying drawings, which form a part of my specification.
My invention relates to mechanism for operating the doors of a dump car; the object of the invention being the provision of means whereby anti-friction bearings between the doors and the operating members or shafts will be obtained and the operation of the doors greatly facilitated, as will more fully be understood from the following detailed description.
In the drawings Figure 1 is a` side elevation and partial sectional view of a portion of the car with my improvements secured thereto, the doors being sh wn in closed position. Fig. 2 is a transverse sectional view of the lower body portion of a car, disclosing the application of my invention. Fig. 3 is a vertical sectional view taken on line 3 3 of Fig. 2 looking in the direction of the arrows. Fig. 4 is a sectional View taken on the line 4 4 of Fig. 3 looking in the direction of the arrows with the member and its anti-friction bearings shown in full lines. Fig. 5 is a perspective view of my invention applied to a door with merely a portion of the door operating mechanism and the door being shown.
As an exemplification of my invention, I have illustrated the invention applied to a dump car provided with the downwardly swinging doors 5, 5, the doors being suitably hinged or pivoted at 6 in close proximity to the central longitudinal sill or member 7 of the car. The transverse members or beams 8 are shown provided with the inclined slot-ways 9, 9, for the purpose of receiving the door operating shafts or sustaining members 10, 10, which, in the construction shown, extend longitudinally of the car beneath the doors, see Fig. 2. The slotways 9, 9, are preferably provided with a horizontally extending portion at the upper ends, or rather the ends in proximity to the doors, when the latter are closed. In the construction illustrated, the shafts 10, 10, when the doors are closed, will rest between Specification of Letters Patent.

Serial No. 628,273.
two parallel surfaces, that is between the doors and the horizontal portion of the slotways or tracks, thus relieving the shafts of any rotative tendency and transmitting the weight of the load on the doors to the weight-carrying members of the under frame of the car. shown provided with sprockets 11 which mesh with the racks formed by the short pins or stubs 12 located at the under sides of the slot-ways or tracks, as clearly shown in Fig. 2, thereby providing a positive or rolling engagement between the operating shafts or members 10 and the transversely extending members or beams of the car. Any suitable means may be employed for inducing the rotation or movement of the members or shafts 10.
The under sides of the doors are preferably provided with the angle irons or Z- bars 18, extending transversely of the doors, see Figs. 2, 3, and 5. These bars 13 are firmly riveted or otherwise secured to the doors and constitute a track and support for the means or blocks which provide anti-friction bearings intermediate of the shafts or operating members and the doors. In the particular exempliiication of said means, the same is composed of the two side members 14 and 15, which are preferably curved or arched intermediate of their ends as clearly shown in Figs. 2, 4, and 5, thereby providing downwardly extending portions between which the rollers 16 and 17 are mounted. The side or member 14 is preferably bent at right angles so as to extend over the horizontally extending portion of the Z-bar 13, See Fig. 3, while the other side or member 15 extends up adjacent to the vertical portion of the Z-bar 13. The two sides or members are secured together in any suitable manner, as for example by the retaining bolt 19, which may be either provided with shoulders or with a sleeve or spacing block 18, so as to maintain the two sides in proper relation to each other and afford freedom for the rollers 16 and 17. It is evident from the construction just described that the roller-carrying` means or blocks will be slidably or loosely held on the bottoms of the doors; while at the same time the rollers 16 and 17 will bear against the operating shafts, or, as in the construction shown, on the sleeve 11a of the sprocket 11, mounted on the operating shaft and also against the The shafts or members 10 are Z-bars, thus providing a constant antifricl tion bearing between the doors and the operating shafts.
It is evident from the construction, that with the rollers 16 and 17 cont-acting with different points on the periphery of the operating` shafts or the sleeves mounted thereon, that is to opposite sides of the vertical plane through the center of the shaft, any movement of the operating shafts will compel the antifriction means to move` therewith, so that the doors will have constant antifriction bearings on the shafts whereby the operation will be greatly facilitated.
It is evident from the construction shown and described, that my invention is equally 'applicable to other types of cars and forms of operating mechanism; furthermore, the construction may be modified in certain details without departing from the spirit of my invention, and l do not wish therefore to be understood as limitingmyself to the exact construction shown and described, but
`What I claim as my invention and wish to secure by Letters Patent is l. A dump car having a floor comprising downwardly swinging doors, a shaft mounted in the frame of the car to roll thereon and operate the doors,vand rollers interposed between the shaft-and the doors and mounted on the latter. 't
2. A dump car having a floor comprising downwardly swinging doors, a shaft mounted in the frame of the car and having rolling engagement therewith, and means loosely mounted on the doors to provide rolling engagement between the doors and the shaft. 1 f
3. A dump car having a floor comprising downwardly swinging doors., a shaft mounted in the frame of the car, and having rolling engagement therewith, and means loosely mounted on the doors and provided with anti-friction rollers for providing rolling engagement between the doors and the shafts, the relation between the shafts and the rollers being such that the means will travel with the shaft.
et. Door operating mechanism for the Led in' the frame of the oar to support the doors in closed position, 'said shaft having rolling engagement withthe frame of the car, and anti-friction rollers slidably mounted on the doors to provide rolling engagement between the doors and t-he shaft.
6. Operating mechanism for the downwardly swinging doors of a dump car, comprising supporting members adapted to travel beneath the car, and means interme-x diate of the supporting members and the doors, slidably mounted on the latter, adapt- Y ed to travel with said members, to provide anti-friction bearings between the members and the doors.
7. Operating mechanism forrthe downwardly swinging doors'of a dump car and the like, comprising bearing members.k eX- tending transversely along the bottoms'of the doors and connected thereto, operating vmembers movable transversely beneath the doors, and means slidingly connected with the bearing members and adapted to travel with said operating members, said means providing anti-friction bearings between the bearing members and the operating members.
8. Door operating mechanism for thel doors of a dump oar, consisting of shafts rotatably mounted beneath the doors, and members slidably secured to the ,bottoms of the doors, provided with a number of rollers so arranged that the diferent rollers Vwill engage with points'on the periphery of the shafts at. opposite sides of the vertical axis thereof. y Y
