IMPROVEMENT IN CAR-DOORS.
Specification forming part of Letters Patent No. 1 56,540, dated November 3, 1874; application filed July 29, 1874.
To all whom it may concern:
Be it known that I, DAVLD CONNOR, of Marshalltown, in the county of Marshall and State of Iowa, have invented an Improved Grain- Door for Railroad-Oars, of which the following is a specification:
The object of my invention is to provide a simple and durable means of closing the doorway of a car designed to carry grain in bulk. It consists in attaching stationary eyebolts and corner-stops to the doorway, and boltrests or bearings and a dowel-bar to the door, in the manner hereinafter fully set forth.
Figure 1 of my drawing is an inside view of the door and doorway.
A represents a wooden door, which may be framed together in any suitable way. B B
are the eyebolts, rigidly attached to the frame of the doorway to project inward and pass through corresponding slots in the ends of the door. 0 O are metal chucks attached to the door to engage the eyebolts B and form bearings for their keys D, suspended by the chains M. Their tops have an angling surface to retain the keys D at an angle that will prevent them from jolting out of the eyebolts. The slots 0 in the chuck 0 correspond with the slots through the door, and allow the door to be raised sufficiently to be disengaged from the corner-stops and dowel, which secure it at its lower edge, and also from the eyebolts B near the top. F represent metal plates on the door A and doorway J J, to add strength and prevent the wearing of the wood. G G are metal stops rigidly attached at the bottom corners of the doorway, to receive and retain the corners of the door. I
Fig. 2 is an outside view of the door A and door-frame J.
K K are the ends of the eyebolts B, secured with washers and nuts. H is a dowel-bar, rigidly attached to the central and lower part of the door, and is designed to enter a corresponding mortise, L, in the door-sill. I I are notches cut in the bottom of the door, to admit iron bars and facilitate the opening and removal of the door, and the unloading of the grain.
I claim as my invention- 1. The door A for grain-cars, having the chucks O, with angling top surfaces and vertical slots 0, in combination with the eyebolts and suspended keys D, substantially as described, and for the purposes specified.
2. The door A for grain-cars, having metal plates F and dowel-bar H, and notches I- in the lower edge, in combination with a doorsill having corner-stops G and a mortise, L, substantially as and for the purposes specified.
