SPECIFICATION forming part of Letters Patent NO. 788,321, dated April 25, 1905.
Application filed August 22, 1904. Serial No. 221.653.
1" 0 rtZZ whom it may concern:
Be it known that I, EDWARD F. MARTIN, a citizen of the United States. residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Car-Doors, of which the following is a specification.
My invention relates to improvements in car-doors, with especial reference to that class of doors used for grain-cars and which are arranged to slide vertically against the inner face of the door-posts.
The object of my invention is to provide a form of structure in which leakage of grain between the door and door-posts will be pre vented.
Attempts have heretofore been made to provide interacting strips or sheaths designed to prevent leakage of grain; but a difficulty has been experienced with'such devices in practical use owing to the fact that the door-posts bend when the car is heavily loaded and weave when the car is in motion, thus separating the interacting parts and destroying their efficiency.
My invention contemplates the provision of means whereby one of the parts will automatically adjust itself to the other independently of the movement of the door-post.
In the following description reference is had to the accompanying drawings, in which Figure 1 is a side view of a car to which my' invention is applied. Fig. 2 is a detail view showing a portion of the car in horizontal section drawn through the door-posts and door. Fig. 3 is a detail view of the inner face of one of the door-posts, showing a movable metallic sheath attached thereto. Fig. 4 is a detail view of one of the vertical end rails of the door, showing a metallic sheath adapted to fit the sheath shown in Fig. 3.
Like parts are identified by the same reference characters throughout the several views.
A is the side wall of a car, and B the doorposts. A metallic sheath C, preferably comprising a strip of sheet metal, is secured in substantially a vertical position to the inner face of each door-post and is provided with a series of horizontally extending slots D, through which screws E are passed, whereby the sheath C is secured to the post, but permitted to move independently thereof in a horizontal direction. The edges of the sheath around the slots are beveled or countersunk to receive the heads of the screws E, as shown in Fig. 3. The central portion of each sheath C is provided with a vertically-extending rib F, preferably formed by bending the sheath along its longitudinal central line. This rib F is adapted to fit a channel G in a sheath H, which is secured to the vertical end pieces I of the door J, the side edges of the sheath H being preferably embedded in suitable channels in the vertical sidepieces I, as shown at it in Fig 2. Screws K are also employed to hold the sheath H in position.
I attach great importance to the fact that one of the interacting sheaths C or H is permitted to move in a horizontal direction along the surface to which it is attached, as it is thus permitted to remain in registry with the counterpart sheath although the door-post may bend under the Weight of the contents of the car or weave when the car is subjected to strains while in motion.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a railway-car provided with a suitable doorway and door-posts, the combination of a door adapted to move vertically along the inner faces of the door-posts; sets of interacting metallic sheaths secured to the opposing surfaces of the door and door-posts respectively and means for permittingashifting horizontal movement of one of the sheaths of each interacting set along the surface to which it is secured. I I
2. The combination with a railway-car provided with a suitable doorway and door-posts; of a door adapted to move vertically along the inner faces of said posts; a set of interacting metallic sheaths interposed between each doorpost and the opposing surfaceof the door;
one of said sheaths being secured to the door and the other of said sheaths being secured to the post, one of said sheaths being provided with slots through which the securing devices are passed, whereby said sheath is permitted to move horizontally along the surface to which it is attached.
In testimony whereof I aflix my signature in the presence of two Witnesses.
EDWARD F. MARTIN.
