GRAIN-DOOR FOR RAILROAD BOX-CARS.
SPECIFICATION forming part of Letters Patent No. 706,626, dated August 12, 1902.
Application filed June 27, 1901.
.To @ZZ whom t nir/ay concern:
Beit known that I, JOHN W. WOOD, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Grain- Door for Use in Railroad BOX-Cars, of which the following is a specification.
My invention relates to improvements in grain-doors which slide up and down on hang- Io ers attached to the top beam of car; and the zo essary to detach the grain-doorin unloading.
A further object of the invention is to simplify the construction and provide' a strong efficient door whose operation can be easily understood by trainmen and which will not be liable to injury in opening it. Provision is also made for swinging the door up to the roof of the car when the car is to be used for other goods than grain.
My improved door is made to cover the 3o lower half of the car-door opening and has at 4o tened by a hook or chain.`
each edge two eyes, the upper one smaller than the lower. Two straight hangers are pivoted to the upper portion of the car-door frame and pass through the upper eyes. The ends of the hangers are hooked, but capable of passing through and engaging with the lower eyes when the door is raised. In this suspended position the door and hangers can be swung up against the car-roof and fas- The main door is provided with an opening closed by a small auxiliary door hinged at its upper. edge and opening outwardly. It is secured by a hasp or other suitable fastening device. c
In the accompanying drawings, Figure 1 is an elevation of my improved grain door viewed from inside the car in its operative position. Fig. 2 is a vertical section showing the small door open in dotted lines. Fig. 3
5o shows the door lifted and engaged with the pended.
hangers. Fig. 4 is a cross-sectional view of Serial No. 66,311. (No model.)
a portion of the car, showing the door raised and fastened to the car-roof.
The car is of the usual boxl construction, having a side, door opening framed by the posts A and plate B. Fastened to the inside of the plate above the posts areU-shaped hinge-irons C, on each'of which is hinged a hanger D, preferably made of strapiron,with a hook d at its lower end.
'The grain-door E is built of plank laid in two layers each transverse tothe other and strengthened by upright battens E. At each upper corner is a projecting metallic eye F of such a size'as to slide easily onthe hanger,A but too small to'pass over the hook CZ at its lower end. At each lower corner of the door is a similar but larger eye F', large enough to allow the hook d to pass through it. In the lower part of the door isan opening with a rab- `beted edge, in which fits a small auxiliary door G, made up of two transverse layers of plank and having a correspondiugly-rabbeted edge. The door Gis hinged to the outside of themain door at its uppenedge by hinges g, and its lower edge canbe secured to the main door by suitable fastening devices, such as a hasp H, engaging with a perforatedl `stud H and secured by a pin h. 7.
vThe operation of my device is as follows: When the pin 7L is. knocked out, the weight of the grain will force the small door open, as shown in Fig. 2. As soon as the pressure on the main door has beengrelieved it can be lifted until the hooks dpass through and engage the eyes F', thus holding the door sus- If desired, the hangers may have a slight springing action to keep them engaged. lVhen the door is to be put out of the way, so that the car may be loaded with goods other than 'graimthe door and hangers can be swung up on the hinges until parallel with the carroof, where they can be fastened by a short chain I, engaging with the stud H',
or by any This door is simple in construction and can be easily and cheaply applied to existing cars. Its operation is evident atfa glance, and thus there is no danger that the door will be injured by unskilled trainmen in endeavoring to open it, as frequently happenswith more complicated or unusual constructions.
