Specificatio ters Patent. Patented Sept. 12, 1916.

Application filed Ma 31, 1916. Serial no. 100,840.

The present invention relates to improvements in railway car doors, especially applicable for use in connection with freight cars as a door to render the interior of the car waterproof and weather proof in order to protect the contents of the car. At present the almost universal practice obtains of using tar paper, laths and nails to render the standard car doors waterproof when the car is loaded with perishable material, and this custom is not only expensive, but requires time and labor, and at best is not effective for the purpose. By 'the utilization of the door of my invention I am enabled to quickly and effectively render the interior of the car waterproof to protect the merchandise therein, at comparatively slight expense and with the expenditure of little time or labor.

In the accompanying drawings I "have illustrated one complete example of the physical embodiment of my invention constructed according to the'best mode I have so far devised for the practical application a of the principles of my invention.

Figure 1 is a "iew in side elevation ofa door embodying my invention and showing its relation to a railway freight car. Fig. 2

. is an enlarged vertical sectional view at line 22 of Fig. 1. Fig. 3 is a horizontal sectional view at line 3-3 of Fig. 1. Fig. 4 is a vertical sectional view at line l-4 of Fig. 1.

In order to illustrate the physical embodiment of my invention I have utilized the standard freight car as indicated at A, which is provided at one side of the car door opening with a jamb strip B extending vertically and firmly secured to the car wall, while at the opposite side of the door opening a vertically extending groove A is arranged, approximately 4 from the edge of the doorway or wall. The flooring of the car is indicated at C which is provided with a sheet metal sill plate D, and a bolster E is indicated in Fig. 2. In this figure it will also be evident that I have added a stripor bead as E which may be of wood and is extended longitudinally of the car, just under the projecting and protecting edge of the sill plate D and as long as the door. This strip extends from the jamb past the opposite side of the doorway and acts as a guide bead or tongue, as well as a waterproofing agency for the door which is indicated by the numeral 1.

The door is of usual construction and is adapted to roll into and out of position, be-

ing supported on the pair of rollers or wheels 2, 2 which travel on the rail or track 3 supported by a series of brackets 4L, 4:, etc securely fixed to the car wall and arranged in alinement. A side rail 5 is also supported by these brackets and the side plate 6, of metal, attached at the lower edge of the door, at its outside, is adapted for use as a wear plate for contact with the side rail, as well as to inclose the wheels 2 2 in their housings. The wheels are journalecl in plates 2 fixed to the under side or bottom edge of the car door, and preferably are of the ball bearing type.

The door may be manipulated by grasping the handle 7 which is fixed tothe outside of the door near one edge, and at the upper edge or top, the usual guiding strip 8 is employed which is attached to the car by fastening devices 9 and overhangs the door to protect it from the weather as well as to act as aguide. Near its lower edge, and on the inside, the door is rabbeted 0r grooved as at 1, and in Fig. 52 particularly, it will be seen that the bead E is inclosed in this V groove 1 and the door is guided thereby in I its movement, and in addition this tongue and'rabbet joint render the door water proof and weather proof at the lower edge.

The rear side, the top and the bottom portions of the door way are thus protected by relatively. stationary parts, while the fourth edge of the door, or the right end in Fig. 1, is protected by a movable weather strip as 10 carried by the door. At 1 the door is rabbeted its entire height and withinthis rabbet or groove the locking or weather strip 10 lies when the door is not closed and sealed. The strip is preferably of wood, although of course metal may be used if desired, and is designed to be projected into an alined slot or groove A in the car wall, before mentioned.

In connection with the movable strip I trated as two in number, and each bolt is pressed escutcheon plate.

provided with a handle or T-head 12 which co-acts with the escutcheon plate 13 which is seated in a mortise provided for the purpose in the door and formed with a perforated wall 14 to guide the turn bolt 11. On each bolt and between the strip 10 and escutcheon wall 14L, a coiled spring 15is provided which is under compression and these two springs continually urge the strip 10 out of the rabbet or groove 1. The door is mortised at 1 to accommodate the, spring, and the strip or tongue 10 is grooved at 17 to accommodate a washer 18 on the bolt 11, and the cotter pin 19 is used to secure the bolt 11 between the strip and escutcheon plate. A pair of handles or steps 20 are illustrated which may be used if desired or necessary to manipulate the turn bolts 11.

In the drawings the strips 10 are-in sealed position being projected from the groove 1 into the groove A by means of the springs and the head of the T-shaped bolts is located in the depression of the escutcheon plate. To withdraw the strips preparatory to opening the car door, the handles 12 are grasped, the bolts pulled out, and then the 7 head 12 is turned at right angles as in Fig.

3 where it bridges the escutcheon. In this position the strip is withdrawn from the groove A and is pulled within the groove 1, the springs 15 being compressed and held under tension by the handle 12 across the de- The door is now free, so far as the strip 10 is concerned, to

be moved at will without danger of the strip encountering any part of the car. In this manner the strip may be held locked in retracted position, and of course when the turn bolts are moved from dotted position in Fig. 3, the springs force the strip into the groove A.

From the above description taken in c011- neetion with the drawings it will be seen that the door is rendered weatherproof at the two sides, as well as the top and bottom, and at the same time all of the waterproofing or weatherproofing elements perform additional functions. Thus the jamb B acts as a stop for the door, the tongue E co-acts with the rabbet 1 to guide the door, and the metallic strip 8 also guides the door at the top, while the movable weather strip 10 acts also as a locking strip for the door.

What I claim is The combination with acar having door supporting means and a vertically extending groove adjacent to its door opening, of a door formed with a complementary groove and a weather strip therein, T-shaped bolts passed through the strip, said door having a pair of openings therethrough and perforated escutchcons in said openings for the bolts, a spring coiled about each bolt between the strip and escutcheon, and said bolts adapted for withdrawing the strip and holding it in inoperative position.

In testimony whereof I aflix my signature.

JOHN U. ROSS.
