CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 7 35,556, dated. August 4, 1903.

Application filed November 15, 1902. Serial No. 131,554. (No model.)

to handle or operate, and, further, to provide means to make the door grain-tight.

I will describe a car-door embodying my invention., and then'point out the novel features in the appended claims.

Reference is to be had to the accompanying I drawings, forming a part of this specification,

vin which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a car-door embodying my invention. Fig. 2 is a vertical section thereof. Fig. 3 indicates the door in its raised or open position. Fig. i is an outside elevation thereof, and Fig. 5 is a section on theline a; 0c of Fig. 1.

The door comprises a lower or main section 1 and upper sections 2 3, mounted to .swing t l These several sections preferably consist of metal,-

with relation to thelower section.

but they may be formed of wood-without d'eparting from the spirit of my invention. At the upper edge of the section 1 is a flange 4, engaging with a flange 5 on the lower edge of the section 2, and rings 6 are passed through perforations inv these flanges, thus formingl hinges. The upper edge ofthe section',2 is

provided with a iiange 7, engaging with a.l

iange 8 on thev lower edge of the section 3, and rings 9 are passed through perforations in these ilanges toform hinges. It will be noted that the sections 2 3 are each formed of two plates, the outerplate'being extended below the inner plate, so as to break or close the joint, thus preventing escape of grain through the joint.

The door-posts consist of angle-irons 10, secured to the frame-posts 11, and these posts 10 are provided with channels 12 for receiv- -ing a packing 13, consisting of rope or similar material, and this packing also extends y along the lower -vedge of the door and is engaged thereajt on its upper side by ametal plate 15. The rope is held in place by means of nails or pins passing through perforations in the metal parts and also through the rope. When the door is closed, the several sections are held in close connection with the packing by means of hooks 146, attached to the doorposts and engaging with eyes 17 on the doorsections.

Arranged on the inner side of the car are guide-rods 18, which pass through eyes 19, attached to the upper portion of the lower section 1 of the door and having a rotary motion. At the upper ends'of the rods 1S are hooks 20, with whichthe eyes 19 may be engaged when the door is in an open position, as indicated in Fig.' 3.

For convenience in raisingthe door handpieces 21 are attached to the outer side of the lower section, and also attached to the lower portion of the lower section is a yoke 22, designed to be engagedwith a hook 23, attached to the car-ceiling.

In operation when loading a car with grain the lower section of the door is to be closed and fastened. Then as the grain approaches the top thereof the upper sections areto be swung upward and secured by the fastening devices. When the'door is to be opened, the upper sections are to be turned down upon the inner side Patent- 1. Afcar-door, consisting of a plurality of sections, inwardly-extended flanges at the abutting edges -of the sections, and hinge connections between connecting-danges, rods arranged at the sides of the door, eyes on the lower section of the door through which said rods pass, said eyesy being mounted'to rotate, hooks von the upper ends of the rods, and a hook attached to the car-ceiling for holding the door in 'a suspended position, substantially as specified.

2. VA car-door constructed of metal and comprising a lower section having a flange on its upper edge, an upper section having a flange at its lower edge for engaging with the first-named flange, the said flanges beingper'i IOO extended flanges at the abutting edges of the sections and hinge connections between adjacent anges, metal door-posts, hooks attaohed to the posts, and eyes on the door for receiving said hooks.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
