To aZZ whom it may concern.-

Be it known that we, JOSEPH H. GOODE, WVI LDIAM H. ANTHONY, and THOMAS S. LLOYD, residing at Richmond, in the county of Henrlco and State of Virginia, have invented a new and Improved Grain-Oar Door, of which the following is a specification.

Our invention relates to inside grain doors for cars, and it has for its object to provide a door of this character simple in its construction, easily manipulated, and very effectiye for its desired purpose, and such inventlon consists in the peculiar combination and novel arrangement of parts, as will be hereinafter described in the specification and particularly pointed out in the claims, reference being had to the accompanying drawings in which-- Figure 1 is an inside face view of a grain car door constructed in accordance with our invention. Fig. 2 is a vertical longitudinal section thereof on the line 2-2 Fig. 1. Fig. 3 15 an enlarged sectional view of the slide operating mechanism and Fig. 4 is a horizontal section of the door way, the outside car door being shown in dotted lines in a closed position. the supplemental fastening device hereinafter referred to.

lteferring to the accompanying drawings A indicates a portion of the car body, B the outer and O the inner lining of the side wall thereof. D denotes the door opening, to the posts D' of which the lining portions B and O are connected as most clearly shown in Fig. 4 of the drawings.

On the floor E of the car adjacent the inner face of the door way is disposed a casting F extending longitudinally across the door way, and continued at one side as at F adjacent the inner wall or lining O, and par allel with such casting F is arranged at the inner edge of the door way a plate G.

By referring now to Fig. 3 it will be noticed that at the inner edge of its upper face, the plate F has a groove or guide way f which in connection with the plate G and the lining wall 0 forms the bottom guide or track way for the out oif or slide bar H, which is Fig. 5 is a detail view, illustrating opposite post, and is held closed by a gravity catch J, as shown in Fig. 1, and in the practical construction a similar catch is used on the inside of the car to hold the door to its open position.

As will be noticed in Fig. 2 the bottom of the door does not extend to the floor of the car, leaving as it were a grain discharge opening extending entirely across the door opening, which when the car is filled, is held closed by the slide or cut ofi H before referred to. This slide which is in the nature of a shaped casting has vertical flanges h k at its upper and lower ends the lower one 7& of which rides in the way f while the upper flange slides in a groove 1 on the inner face of the lower edge of the door as shown. The inner face of the upper horizontal portion of the slide H is formed asa rack member, with which engages a cog gear K, on the inner end of a shaft journaled to one side of the door opening, to the outer end of which is secured a crank handle L. This handle L is formed of a link arm Z pivoted on the end of the shaft is, as shown most clearly in Fig. 3, in the outer bifurcated end of which is pivotally connected the handle Z. It will he noticed by reference to such Fig. 3, that the link Z and crank handie Z are so joined that when lowered for operating the shaft is they assume the position shown in full lines in Fig. 3, but when out of operation they will extend in the same vertical plane, as shown in dotted lines in such figure. When in the latter position, the handle portion Z of the crank handle will pass through a hole a. in the side of the car, while its shank, which has an aperture Z will fit over a staple M such handle being held in place by the chain and staple devices N as shown. It should be stated however that while the staple will serveto firmly hold the handle in place, it is held locked by the seal 0 which is attached to the staple M as shown when the car'is loaded and ready'for shipment.

lo prevent the lower slide section H from belng operated after the car is loaded and the outer door is closed and locked, and in case the lever L is moved from its locked position, we provide a supplemental locking dev ce 1n the nature of a pin P, attached to a chain Q connected at its upper end to the upper or swing door I; and such pin passes through an aperture in the upper end of the slide member H and a notch in the lower 7 edge of the door I as most clearly shown in Fig. 5. By this construction it will be read- 11y seen that after the car is loaded and the front or outside door locked should the lever L in any manner become unlocked it will be lmpossible to operate the slide member H through the medium of the cog and rack devices until after the outside door is unlocked and pin P withdrawn.

From the foregoing description taken in connection with the drawings, the advantages and operation of ourimproved door will readily appear.

It will be seen that after the filled car reaches its destination and it is desired to empty the same the outside door is opened, the seal is broken, and the crank handle turned down to operate the shaft, to draw the slide H back to partially or entirely open the discharge mouth under the door, as may be desired. It will also be noticed that by hinging the door to swing inward, it will be impossible to open the door so long as the grain level inside is above the bottom opening.

Havingthus described our invention, what We claim,and desire to secure by Letters Patent, is

1. As an improvement in grain car doors, the combination with the door way, of a cut ofi slide movable over the lower or discharge end thereof, a swinging door movable over the upper part of such opening, means for locking the slide to its closed position, a lock device for connecting the door and slide, to hold the slide from movement substantially as shown and for the purposes described.

2. As an improvement in grain car doors, the combination with the door way, the door hinged to swing inward, and to cover the upper part of the opening, said door having a guide flange at its lower end, and a guide way on the car floor, of a slide or cut ofi, movable over the lower or discharge end of the door opening, said slide having guides fitting the flange on the car doorand the way on the car floor and means for locking such slide to its closed position substantially as shown and described.

3. The combination with the door way D, the guide way at the bottom thereof, the hinged door I having a groove I on its lower end, of the slide H having flanges fitting the groove I and the floor guide, said slide having a cog rack portion, the operating shaft is and gear K, a crankhandle and means for locking such handle from movement sub stantially as shown and described.

4:. In a grain car door, the combination with the door opening and the aperture (1,, the base guide way, the swinging door I formed with a groove I at its lower end, of the j shaped slide H having flanges h 71 fitting the ways I and F and an internal cog rack, theshaft and 'gear 70 and K, the crank handle formed of pivoted members H, the member Z having a slot, the staple M fitting the slot in the member Z when raised and the lock chain N,

all arranged substantially as shown and described.
