Specification of Letters Patent.

Patented June 5, 1917.

Application filed February 25, 1914. Serial N 0. 820,873.

To all whom it may concern:

Be it known that I, FRED J. HARDY, a citizen of the United States, residing at Corbettsville, in the county of Broome and State of New York, have invented certain new and useful Improvements in Gar-Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in car doors and more particularly to means for locking the doors in secure position so that accidental derangement of the door is eliminated.

An important object of my invention is to provide a car door of the character clescribed which is particularly adapted for use in connection with grain cars, but may be used for other purposes, that will seal the opening for the door in such a way that leakage of grain is positively prevented.

Another important object of my invention is to provide simple and inexpensive means for locking the door which is adjustable to coact with doors of different thicknesses and capable of being easily and readily operated and also do away with the employment of nails which interfere with the doors and are extremely undesirable.

A still further important object of my invention is to improve car doors so as to render them more practical, reliable and efiicient in operation, cheap to manufacture and commercially desirable.

The above and additional objects are ac- I complished by such means as are illustrated in the accompanying drawings, particularly pointed out as claimed.

In the accompanying drawing:

Figure 1 is an inside elevation of a car showing my door in assembled and locked position,

Fig. 2 is a vertical sectional view taken on line 2-2 of Fig. 1 showing my door in locked position,

Fig. 3 is a fragmentary sectional view taken on line 33 of Fig. 1 showing the locking cam in cooperation with the locking bars for holding the door in locked position and showing the position of the locking bar as it would assume when cooperating with a thin door,

Fig. 4: is a fragmentary vertical sectional view taken on line 4% of Fig. 1 showing a portion of the door and locking bar in locked position, and

Fig. 5 is a sectional detail view, taken on the line 5-5 of Fig. 1, but with the door removed.

Referring to the drawings by characters of reference the numeral 1 designates the floor of a car equipped with a door frame designated 2. Mounted upon the inside of the car with relation to the frame 2 is a door 3.

The door 3 extends from the floor 1 up to about one-half the distance between the floor l and the roof of the car, and said door is disposed upon the inner side of the door frame 2 of the car. The locking bars a and 5 engage the inner face'of the door 8 at opposite sides thereof, said locking bars being permanently held against removal or detachment by the clamping devices at the top and the slotted keepers at the bottom.

The lower ends of the locking bars 4 and 5 are mounted in slotted plates 7, supported slightly above the floor 1 by means of the blocks 6 and said plates are provided with L-shaped slots 8, so that the lower ends of the locking bars 1 or 5 may be disposed in either branch of the slots 8 depending upon the thickness of the door to be used. The longer branch of the slots 8 permits the looking bars a and 5 to be moved laterally to accommodate doors of different widths.

The upper ends of the locking bars 4 and 5 extend up into casings 12 comprising spaced blocks in which are journaled cam rollers 9 having eccentric pintles 10 extending through the depending blocks. Connected to one of the pintles 10 is a ratchet wheel 14: provided with a handle 15, and pivoted at the side of one of the depending blocks is a pawl 16 to engage the ratohet wheel 14.

The locking cams 9 are designed to force the bars 1 and 5 into gripping engagement with the door 3 by engaging the upper ends of the bars 1 and 5, said upper ends being positioned within the casings 1.2. Locking pawls 16 are pivoted upon the casings 12 exteriorly thereof and coiiperate with the ratchet' wheels 161 to hold the bars a and 5 in clamping position. The locking pawls 16 are held into operative position by force of gravity as will be clearly seen with reference to Fig. 2 in the drawings.

In operation when it is desired to raise the door, the door is moved upwardly be? tween the bars 4 and and the handle eflicient car door which will meet with all the requirements of car doors and positively prevent leakage of grain from the car.

The locking arrangement forming a part of my invention serves to hold the doors clamped after the cars have been unloaded. One of the most essential points of my invention is the fact that the bars t and 5 are permitted adjustment for use in connection with doors of different thicknesses.

What is claimed is i The COIHblHfi'GlOllWlllll a car having a door opening, of casings located at the opposite Copies of this patent may be obtained for portion of the door opening and provided with slots having branches extending longical bars having their upper ends arranged in the casings in position to be engaged by the cams, said bars having their lower ends operating in the slots of the said plates and adapted to be placed in either branch to arrange them diiierent distances from the side of the bar to accommodate doors of diflerent thicknesses, the said cams being adapted to clamp the bars in either position, and pawls and. ratchets for locking the cam in engagement with the bars.

In testimony whereof I affix my signature in presence of two witnesses.

FRED J. HARDY.
