Description
JOHN SWEENEY, OF NEW HAVEN, CONNECTICUT, ASSIGNOR OF ONE-THIRD OF HIS RIGHT TO JAMES T. LEIGHTON, OF SAME PLACE.
CAR-DOOR.
SPECIFICATION forming part of Letters Patent No. 232,153, dated September 14, 1880.
.Application filed J une 24, 1880. (No model.)
To all whom it may concern.:
Beitknown that I, JOHN SWEENEY, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and use ful Improvements in Car-Doors; and I do hereby declare the following to be a full,clear, and exact description ot' the invention, such as will enable others skilled in the art to '1o which it al'ipertains to make and use the same, reference being had to the accompanying drawings,and to letters or iigures of reference marked thereon, which form a part ot' this specification.
x5 This invention relates to doors for boxecars; and it consists in the peculiar construction and combination ot' parts hereinafter set forth and claimed. I
The same letters of reference indicate the zo sainepartsin thedift'erent gures of' thcdrawings.
Figure l represents an exterior elevation of my improved door, and Fig. 2 an elevation of the same taken from the inner side.
The doo as a whole runs on rollers on the outside of the car, so that it may be shifted horizontally toopcn or close the doorway in the usual manner.
A designates the wooden body of said door, consistingof strips a; and B, a metallic frame which incloses it. This 4frame consists ot' side walls, 3 Bf, and cross-pieces B2. The sides B are provided with exterior flanges, b, oneto each wall, running the entire height of the 3 5 vertical edge oi" the door and overlapping` and bracing the wooden body A. The horizontal cross-pieces B2 are provided with feet b', whereby they are secured to the said side walls, B. These cross-pieces are made of angle-iron,and the vertical portion of each crosspiece is constructed with a series of slots or horizontally-elongated holes, b2. Spaceis left for the wooden body Abetween the cross-pieces B2 and the exterior flanges, b, and the said body A is secured to the frame by screws C,
or equivalent fastening' devices, which pass through said slots or holes b2.
The wooden body A preferably consists, as
shown, ot a series ot' strips of sheathing arranged edge to edge; and to provide for the 5o unequal expansion oi' the several strips the oblong slots b2 allow them to contract or expand, according to the dr yness or moisture of the air without straining on the points of attachment.
The outer ianges, b, protect the 'wooden part ot' the door from injury at the points where it is most exposed. They may be extended across the top and bottom ot' it also, if desired.
The door cannot warp, as the cross-pieces B2 will not bend. Hence it necessarily always retains its proper shape and is in condition for service.
The angular construction ot' all parts of the 65 frame B secures the greatest possible amount of strength consistent with the requisite degree of lightness.
Having thus fully described my invention, what I claim as new, and desire to secure by 7o Letters Patent, is-
l. In combination with the wooden body A, the metal frame B, consisting of side pieces, B', havin g exterior ilanges, l), and cross-pieces, B2, having feet b', the said body A being se- 75 cured to said cross-pieces.
2. In combination with frame B, having cross-pieces B2, which are provided with slots or oblougholes b2, the fastening-screws C, passing through said slots, and the strips a, form- 8o ing the wooden body A, and held by said screws in said frame in such manner as to allow contraction or expansion, as set forth.
3. A car-door consisting of a metallic frame and a wooden body.
Il. A car-door consisting of a metallic frame and a wooden body, said parts being constructed in such manner as to allow the expansion and contraction ot' the wooden portion ot' the door independently ot' the frame. 9o
ln testimony whereof l affix my signature in presence of two witnesses.
JOHN SWEENEY.
