GEORGE W. STRONG AND GEORGE UHLIN, OF ROSEDALE, KANSAS, ASSIGNORS OF ONE-THIRD TO DANIEL HOAGLAND, OF ROSEDALE,
KANSAS.
,GRAIN-DOOR- SPECIFICATION formingpart of Letters Patent No. 794,819, dated July 18, 1905.
Application filed November 23. I904. Serial No. 234,062.
To all whom it Wool/y concern:
Be it known that we, GEORGE W. STRONG and GEORGE UHLIN, citizens of the United States, residing at Rosedale, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Grain-Doors, of which the following is a specification.
Our invention relates to doors, and especially to those doors known as grain-doors for use in railroad-cars.
The object of our invention is to provide a door which may be operated entirely from the outside of the car.
A further object of our invention is to pro vide a door with a single operation device capable of sliding the door first vertically and then swinging it inwardly and upwardly into the top of the car and securing it thereat by the same device used to move the door.
A further object of our invention is to provide a vertically-slidable and horizontallyswinging door for cars with a fastening device to secure the door in a closed position and operatable from without the car.
With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanyingdrawings, and particularly point ed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims withoutdeparting from the spirit or sacrificing any of the advantages of the invention. I
In the drawings, Figure 1 is a view in side elevation showing our improved grain-door for cars in a closed position as seen from within the car. Fig. 2 is a view of our improved grain-door for cars in end elevation and in closed position. Fig. 3 is a view in end elevation of our improved grain-door for cars, showing in full line the door at its upward limit of vertical movement and in outline as it swings out from the retaining-guide. Fig. 4 is a view of our grain-door in end elevation, showing in outline the door being swung from the vertical position, as shown in Fig. 3, to the position in the top of the car, as shown in full line. Fig. 5 is a fragmentary view of the inner metal facing of the door-jambs, showing at the lower end thereof the retaining-guides and openings to engage the latches. Fig. 6 is a view in side elevation of our grain-car door as seen from without the car, showing the latching device. Fig. 7 is a transverse sectional plan View taken on line 7 7 of Fig. 6.
Like characters of reference designate corre- The facing4-. is provided at its lower end with an outstanding lip 5, curved to embrace the lips 2, as shown in Fig. 7. To the sides of the jambs are secured guides 6, provided with offset portions 7 adjacent to their upper ends and the upper extremities of the jambs. The door is provided with hinge members 8, having trunnions entering the slots in guides 6.
Horizontally above the door, internally of the car and longitudinally thereof, is mounted a rotatable shaft 9, with cables 10 secured thereto and adapted to be wound thereon and secured at their lower ends to the door 1, as by eyes 11. The shaft 9 is mounted at its extremities in suitable bearings 12, and at oneend of said shaft a pinion 13 is mounted thereon. A shaft 14, provided with a wormgear 15, is mounted at right angles to shaft 9, with the worm-gear v15 engaging pinion 13 and extending outwardly through the walls of the car. Externally of the car the shaft 14 is provided with a crank 15 or other convenient device for operating the shaft 14:, the worm-gear 15, and pinion 13.
The metallic facings 2 are provided near their lower ends with openings 16, and the door 1 is provided with longitudinally-slidable latch-bars 17, adapted to engage the openings 16. The latch-bars 17 are suitably mounted to reciprocate in clips 18 and are provided at their inner ends adjacent to the Vertical center of the door 1 with racks 19. A gear 20, suitably mounted in bearing 21, engages the rack 19, and a lever 22 is pro Vided, adapted to rotate the pinion 20 to operate the latch-bars 17.
The operation of our improved grain-door .for cars is as follows: With the parts disposed as shown in Figs. 1 and 2 the crank is rotated, operating the worm-gear 15 and pinion 13 to rotate the shaft 9. The rotation of the shaft 9 winds the cables 10 about the said shaft, drawing the door 1 slidably upward to the position shown in Fig. 3. When thelips 5 are moved to a position above lips 3, the door. Will spring inwardly, as shown in outline in Fig. 3, and the hinge member 8 will swing into the horizontally-disposed offset portion of the guide 6.
The continued rota tion of the crank 15 in the same direction continues to wind the cables 10 about the member 8 by the weight of the door slides shaft 9, swinging the door inwardly and upwardly through the position shown in outline in Fig. 4 and into the top of the car.
' tain the door 1 adjacent to the top of the car,
The cables 10, wound about the shaft 9, will reand the well-known action of the worm-gear will prevent a retrograde rotary displacement of the shaft 9 and retain the door in the 3 top of the car until released by the reverse movement of the crank 15. The reverse movement of the crank 15 permits the door to swing downward in the reverse order described in swinging the door upward until the lips 5' engage the lips 3 and the hinge downwardly in the vertical portions of the When the door 1 has reached of lever 22 forces the latch-bars 17 to enter ou's that the same result will be accomplished by substituting therefor substantially L- shaped outstanding guides and providing the hinge members 8 with slots or openings adapted to engage slidably with the guide.
It is further obvious that other means for rotating the shaft 9 may be substituted for the worm-gear 15.
, It is further obvious that any other approved fastening may be substituted for the latch-bars 17 and the device shown for operating the same and that other minor changes may be made without departing from the spirit of our invention or the scope of the claims.
Having thus described our invention, what we claim as novel, and desire to secure by Letters Patent, is-
1. Adoor for grain-cars provided with trunnions, engaging ways adjacent to the door on either side thereof, seats adapted to limit the vertical movement of said trunnions located near the upper ends of said ways and means for raising the said door to bring the trunnion into engagement withthe said seats, said means being disposed and arranged to thereupon swing the said door inwardly on said trunnions adjacent to the roof of the car.
2. A door for grain-cars provided with trunnions, engaging ways adjacent to the door on either side thereof, seats adapted to limit the vertical movement of said trunnions located near the upper ends of said ways and means for raising the said door to bring the trunnions into engagement with the said seats, said means being disposed and arranged to thereupon swing the said door inwardly on said trunnions adjacent to the roof of the car, and means for automatically retaining the door in any position'in which it is placed while the said door is being lowered as well as while it is being raised.
3. A door for grain-cars, trunnions mounted on forwardly-extending offset brackets and engaging ways adjacent to the door, seats adapted to limit the vertical movement of the said trunnions near the upper ends of the said ways, and means for raising the said door to bring the trunnions into engagement with the said seats, said means being disposed and arranged to thereupon swing the said door inwardly on the trunnions adjacent to the .roof of the car, the said means being suitably connected to the door at the inner side thereof.
4. A door for grain-cars provided with trunnions engaging ways adjacent to the said door, seats adapted to limit the vertical movement of saidtrunnions located near the upper ends of the said ways and outward with reference to the plane of said door, a revoluble cablewinding shaft mounted above the said door andinward with reference thereto, cables from the said shaft connected to the said door at the inner side thereof, and means to operate the said shaft.
ln testimony whereof we afiix our signatures in presence of two witnesses.
