' pockets 8 are correspondingly elongated for permitting travel of the respective roller 6 during operation. The rollers, 6 rest upon the upper surface of the track or way and sustain the hangers which in turn sustain the door, and, to limit lateral shifting of, the door, during its .edgewise travel,,a roller 9 is disposed To all whom it may concern:

Be it'known that I, PA'UL M. BEARD, residing at St. Louis, Missouri, and being a citizen of the United States, have invented certain new and useful Improvements in Car-Doors, of which the following is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying draw-i ings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exupper edge of the door contiguous to each bracket 5 and beneath the web of the Z section, being positioned for at times engaging the inner surface of the depending outer flange, of the Z section, and thus limiting outward lateral 'play of the door. It is. to .be' observed that necessity for providing means for preventing roller 6 from leaving the track or way laterally is thus obviated, and at the same time frictional contact of the door 3, With either the side wall of the car or the said depending flange of the Z section, is prevented. 'Each roller 9 may be connected tothe upper-edge of the door in various ways, but preferably by annpstanding spindle or shaft 10 formed integral with or fixed to a U shape connecting plate scribed. as it is obvious that various'modifications thereof will occur to persons skilled. in the art. p

In said drawings: Figure 1 is a view in side elevation of a fragment of a car illustrating an embodiment of the present invention applied thereto. Fig. 2 is an enlarged, detail, fragmentary View illustrat ing one of the hangers in elevation. Fig. is a vertical sectiontherethrough, taken on the plane indicated by line 3-3 of Fig. 2. Fig. 4 is a horizontal section therethrough, taken on the plane indicated by line 4-4 of Fig. 2. Fig. 5 is a detail fragmentary view of a further embodiment of the invention. Referring to the drawing by numerals, 1 is a side wall of a car formed with a door; Way 2, adapted to be closed by a sliding door 3 suspended from a. track or way extending under above, across, and beyond the door-way one block 12 for The said track preferably consists of a 2' block being formed With an inwardly bevsection- 4 having its Web disposed horizon- 'el-ed ordiagonal edge 12 terminating at its tally and its inner flange upstanding and inner end in a straight portion 12'. bolted or otherwise suitably secured to the sidewall f the car. Bolted or otherwise fixed to the door 3, near the upper edge thereof, are hanger brackets 5, each comprising av plate engaging the outer surface the door 3. I

The upper end of each shaft extends roller 9 into a position for engaging'the inportion of Z section 4,'there being each shaft 10, and each path of travel of the rollers 9, a wearing '9. Any suitable closing wedge brackets l4,14c may be provided for engaging and confining the lower edge of the door 3.

'In operation, the door 3 is shifted edgevWise to and from a position closing the doorway, and, in traveling outwardly or to an open position, the shafts 1O slide longiplate and a housing extending laterally toward the car from the upperend of the arm and over-hanging the web of the 2 section comprising the track. In each of said houslaterally extending bearing members] engaging guiding pockets 88 formed in the opposite walls of the housing. The housing isrelatively narrow for accommodating'the width. of roller 6, but, as clearly indicated in Fig. 2, the housing is elongated in the direction of the travel of the door, and the from the same and then the door moves 7 edgewise practically tree from friction, being sustained by the hangers 5 and rollers 6 en 'a 'irn the track or wa and retained h o against frictional contact with contiguous parts by rollers 9. In closing the door, the

horizontally and revolubly connected to'the 5 l1 inclos'ing the upper edge of and riveted to.

beyond the upper surface of the respective.

Above: the doorway-2, 'and extending along the;

strip 13 may be provided forming an inner limit for the edgewise shifting of the rollers tudinally of wedge blocks 12, until freed a limited amount of independent Her edge of a Wedge block 12 fixed to the is moved into ,a closed position,

' closed position, the shafts 1O arrive jamb extends outwardly at each side of the doorway, and the door 3 is freely movable between the depending flange of Z section 4 andthe strip 15 at one side of the. doorway until theshafts 1O engage wedge blocks 12, whereupon-the door is wedged laterally over into firni contact with strips .15 so as to be held against play during transit. The straight edge portions 12 which are engaged by shafts 10 when the door, is complctely closed obviate any tendency of the .door to ride edgewise would exist if the shafts 10 were left in enagement with inclined or beveled surfaces.

b Each roller underlaps the respective block 12 which its shaft engages, thus largely obviating liability of vertical rocking of the movable parts. with two distinct sets of guiding elements, being the rollers 9, which guide the door when loose'and-free to have limited lateral play, and the shafts 10, which guide the door to a tightly closed position.

The shaft 10 which upstands from the upper edge of door 3 may be carried, as indicated in Fig. 5, by an. angle plate 11 which is fixed to or formed integral with bracket 5, plate 11 extending across the upper edge of and engaging the door. Obviously additional means of attachment of plate 11 to the door 3 may be provided, but usually its connection with bracket 5 is smithcie'nt. A fillet or web 11" may be provided for stiffening the connect-ion between the horizontal and vertical legs of plate 11*,

What I- claim is: I

1. In a door structure, the'combination, with a track, a door hanger engaging the same, a door sustained by said hanger, a shaft upstandingfrom the door, and a wedge block disposed in the path of the out of place, such as The door is thus provided.

Copies of this patent may be obtained for five cents .each,

shaft for effecting lateral shifting thereof I during edgewise travel of they door and a roller coaxial withtlx: shaft and disposed for underlapping the wedge block.

2. In a door structure, the combination, with a track, of a hanger engaging thesame,

a door sustained by saidhanger, a wedge block sustained by saidtrack and having a diagonal edge, means upstanding from, the door in position for engaging said diagonal edge and being shifted laterally thereby,

ingedgewise travel of the door, and a roller carried by said upstanding means and adapted'to underlap the wedgelblock.

3. In a door structure, a dodr hanger engaging the same, a door sustained by said hanger,

door in position for engaging vone of the and correspondingly shiftingthe doordur- Y a Z section track,

a horizontally disposed roller carried at the upper edge of the flanges of the track section, a-closing wedge for the door out of the path of the roller,

and guiding means carried by the door ad ditional to'the roller adapted to engage the closing wedge.

4:. Iii a door structure, with a: track and a hanger engaging the same, of a door sustained by said hanger, a shaft fixed to and upstanding from the door, a horizontally disposed roller journaled'on the said shaft, and in the path oftravel of the shaft for shifting the shaft laterally during edgewise travel of the door, the wedge block being out of the pathjof the roller.

5. In a doorstructure, the combination, of a 2 section track, a door slidingly sustained thereby,'a shaft extending from the door, a roller on said shaft disposed. for-eng gaging one of the flanges of the track sectionfor limiting lateral play of the door, and a wedge blo'ckin the p. th of movement of the shaft during edgewise travel of the door, the shaft extending beyond the roller in position for engaging the block for beingshifted laterally and correspondingly shifting the door, the wedge block being out of the path of the roller.
