GRAIN-CAR DOOR.

Specification of Letters Patent.

Patented Aug. 24, 1909.

To all whom it may concern.'

Beit known that i, PETER J. A. Sonnoon, a citizen of the United States, and a resident of Holstein, in the county of Ida and State of Iowa, have made certain new and useful improvements in Grain-Car Doors, of which the following is a specification.

My invention relates to improvements in doors and is especially applicable to doors of grain cars, and it consists in the constructions, arrangements and combinations hereinafter described and claimed.

An object of my invention is to provide a door which will meet the several requirements in loading or unloading` grain and which can be conveniently manipulated to form openings of more or less extent according to the use to which the car is to be put.

A further object of my invention is to provide a device which may be readily attached to the door of an ordinary car, thereby changing the latter into a grain car with exceptional facilities for loading and unloading grain.

Further objects and advantages will appear in the following specification and will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, in which similar reference letters indicate the same parts in the various views, and in which- Figure 1 is a side view of a portion of a car provided with my improved door. Fig. 2 is a view of the door from the inner side of the car. Fig. 3 is an inner view of the door showing it in its raised position. Fig. 4 is a transverse section through the door of a car along the line 4-4 of Fig. 2. enlarged detail view of the roller and casing. Fig. 6 is a view of a modified form of door.

Referring now to Fig. 1 l have shown therein a car 1 provided with a door opening 2 in the side thereof. Disposed in the door opening is a door 3, which is suspended from a track 4 above the upper edge of the door opening by means of the telescopic hangers 5 and 5 as clearly seen in Fig. 2. The latter are arranged to slide in and out of the casings 6 and 6 and may be adjustably secured at various heights by means of the pins 7 and 7 which are adapted to extend through the casing and to enter holes S and S in the telescopic members.

Fig. 5 is an Referring now to Fig. 5, in which the supporting roller is shown in detail, itwill be seen that the top of the telescopic member 5 is pivotally attached to a yoke 9, in which is rotatably mounted a wheel or roller 10. The wheel 1() is arranged to travel back and forth on the track 4, which is secured to the side of the car 1.

In order to prevent the roller from leaving the track l extend one side of the yoke to form a curved hook 9 a, which projects underneath the rail of the track 4. On the outer side of the same yoke member l provide a hook 11, which is arranged to receive a pin 12 adapted to enter an opening 13 in the member 5. The construction described crmits the member 5 to swing outwardly w ien the pin 12 is withdrawn and to be locked securely to the yoke when it is in contact with it as shown in Fig. 5.

The main door 3 is provided with an auxiliary door 14 which is considerably smaller in size and which is provided with the hinges 1'5 to permit the door to be swung upwardly. The auxiliary door 14 mayV be locked by means of a bar 16 arranged to be engaged by a catch 17. Y

Centrally dis osed of the auxiliary door 14 at the bottom t iereof is a round opening 18, which is closed by means of a door 19 having an inner flange 19a arranged to enter the opening 18. This small round door may be locked by means of a bar and latch 2() as shown inthe drawings.

rlhe main door 3, besides being suspended upon the track 4, may be locked to the side of the car 1 by means of the shot bolts 21 and 21. These bolts are pivotally attached at their inner ends to a lever 22 which is pivoted at 23 to the end of a handle 24 extending on the inside of the car. When the handle is turned the bolts are moved inwardly or outwardly guided by the guide members 25 and 25. This arrangement prevents the door from being opened from the outside, but permits the ready unlocking from the inside.

From the foregoing description .of the various parts the operation of the device can be readily understood. ln Fig. 1 the main door is shown in its closed position. It will be observed that there is a space between the upper edge of the main door 3 and the top of the opening 2.

This space is provided for the purpose of filling the car. It may be closed by means of an auxiliary drop-down door 26, shown in Fig. 6, which will permit the 'filling of the car in the ordinary manner and which will swing up to close the space between the main door and the upper part of the opening.

The auxiliary door 14 is for the purpose of unloading the car by means of shovels in the ordinary manner, and it can be swung ontwardly and held up in any convenient main ner while the unloading is taking place. The purpose of the door 19 is to provide means by which a suction pipe can be inserted for sucking up the grain into an elevator. This door has a latch which is automatically locked when the door is shut. The provision of the shot bolts 21 and 21 forms means by which the main door can be held securely. In order to permit the removal of the doors from the opening 2 I have arranged the telescopic members heretofore described. By means of these telescopic hangers the door can be elevated as shown in Fig. 3, the pins 7 and 7 being placed in the proper openings in the telescopic members 5 and 5. rthe provision of the track 4 permits the door to be slid to one side. At times it may be neeessary to lift the door out of the way and in order to accomplish this I have provided the hangers shown in Fig. 5 and already described. In order to suspend the door the pins 12 are withdrawn and the door may be ifted and attached to the top of the car by any convenient means where it will then be out of the way to permit the loading of the car with materials which might otherwise injure the door. t

I am aware that other forms of the device based upon the same general idea might be made but I consider as my own and desire to claim, all such modifications as fairly fall within the spirit and scopey of the invention.

I claim- 1. The combination with a grain car provided with a door opening, of a door therefor adapted to cover said opening, a track disosed above the door opening, telescopic iangers carried by the door, vokes pivoted:

to said hangers, wheels carried by said yokes and arranged to run on said track and means for locking` said hangers to said. yokes.

2. The combination with a grain car provided with a door opening, of a door therefor adapted to cover said opening, a track secured above the door opening, telescopic hangers carried by the door, yokes pivoted to said hangers, wheels carried. by said yokes below the pivotal connection with the hangers, and arranged to run on said tracks, hooks secured to said yokes and arranged to eX- tend underneath the tracks for holding the rollers to the latter and hooks carried by the yoke for locking the hangers.

3. The combination with a grain car door provided with a door opening, of a door therefor adapted to cover said opening, a track secured above the door opening, telescopic hangers carried by the door, said hangers being provided with openings, yokes pivoted to said hangers at their upper ends, wheels carried. by said yokes below the pivotal connection with the hangers and arranged to run on said track, hooks secured to the sides of the yokes and pins arranged to engage said hooks and. to extend into the openings in said hangers for lockingI the hangers to the yokes.
