GRAlN-CAR DOOR.
Specification of Letters Patent.
Patented Feb. 12, 1907.
Application iiled March 10, 1906. Serial No. 305,236.
To ML IJ/2,07% t puny concern:
Be it known that I, JOHN JOHNSON, a citi- Zen of United. States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Grain-Oar Doors, of which the following is a specification.
My invention relates to improvements in grain-car doors, and has for its objects the provision oi a door which will allow of the ready loading and unloading of the car,
which will form a fieriectly-tight closure and orevent loss the grain, and which will allow the removal of the grain either in bulk or in limited amounts.
Other objects oi the invention are the provision of a device of the character stated which can b e quickly stored out of the way when it is desired to load the car with heavy articles and also to 'provide a d 'or which will not become jammed. and stick from the pressure of the grain.
My invention further has 'for its object to provide a grain-car door of simple and durable construction, light and easily manipulated, and practical for the purposes intended.
With these and other objects in view my invention consists of a car-door comprising an upper door-section having a swinging and vertically-sliding movement, a lower doorsection slidably engaged in the upper doorsection and. adapted to engage grooves in the door-posts, means for elevating the doorsections, and a supplemental door-section hinged to the upper portion ot the doorframe.
My invention further consists a car-door embodying certain other novel features of construction, combination, and arrangement of parts, substantially as herein disclosed.
Figure l is a side elevation of a portion ot a car with my improved. door in place thereon. Fig. 2 is a vertical sectional view through the door and a portion of the car. Fig. 3 is an elevation of the door, taken from the interior of the car; and Fig. 4L, a vertical sectional view through the car, showing the door as stored when not in use.
In the drawings, the numeral 1 designates the door-posts of the car, to the lower inner sides ot which are secured the guiding-strips 2, which provide grooves 3 for the reception of the lower door-section 4. This door is preferably of sheet-iron, and brackets 5 are secured near the upper corners thereof, in which are mounted the pulleys 6. Complementary pulleys 7 are mounted in brackets 8, secured to the upper 'portion of the doorframe. '.hese brackets 8 are 'provided with lower extensions 9, in which are secured the hoisting ropes or cables 10, which pass over the pulleys and are adapted to hang down over the outside of the door-section.. The upper door 11 may be if iron, as is the other door-section, and is formed with the inturned edges l2, 'prifviding guideways for the reception of the lower door-section.
To provide 'for the ready inspection of the grain, l. have shown this upper door-section provided at its upper portion with. the removable boards or panels 13, secured thereto by the brackets 14. At the upper corners of this door-section lugs are secured, `which prol vide the horizontal pintles 15, adapted to be engaged by the guide-rods 16, secured to the door-posts. At the upper ends these rods are so bent as to form the retaining-loops 17. Thus it will be seen that the lower door-sed tion may be hoisted and slide up within the flanges of the upper do or-section.
An upper supplementary door-section 18 is hinged at 19 to the door-trame by means oi' the oilset hinges 2() and is provided at its lower edge with the overlapping strip 21 to engage the upper door-section and form a close joint therewith.' A sliding latch 22 is secured in brackets 23 on the outer face of the supplementary door-section and serves to lock said. door to the upper door-section 'when so desired, or by engaging the keeper 24, secured to the car-roof, it serves to secure the door-section in the open position.
An eye 25 is provided at the lower edge of the upper door-section, in which is secured a rope or cable 26, which passes upward over the pulley 27, secured to the root-beam 28, thence to the pulley 2Q, secured to the doori'rame, and down. l
Vhen the car is to be leaded, the suppleinentary door-section is swung up out of the 'way and the upper and lower door-sections are closed. The car may then be filled to its fullcapacity, after which the supplementaryv door-section is closed. and latched and the outside door of the car is closed and sealed.
lf grain is to be removed for testing, the supplementary door-section may be opened, or, if necessary, some of the boards in the upper door-section may be removed, When ready to unload, the lower door-section is hoisted within the iianges of the upper doorsection by means of the hoisting-ropes, and
TOO
IIO
the grain will run out in such volume as del tion slidable within said retaining-flanges,
sired.
When the car is to be loaded with heavy goods and it is desired to store the graindoor section out of the way, the supplementary door-section is 'Iirst hinged up to the roof of the car. The lower door-section is housed within the upper door-section, and the upper door-section is lifted until the pintles engage the retaining-loops in the guide-rods. Then the doorsections are swung up to the roof of the car by means of the rope 26, and the rope is secured in the cleat 30, mounted on the door-post. A doorsill 31, preferably of sheet-iron, is provided7 which prevents leakage of the grain under` the door. A hook or cleat 32 may be mounted in the lower dooresection, so that the said. door-section may be easily started or raised by means of a crowbar or similar tool.
From this description, taken in connection with the drawings7 itfwill be evident that I have provided a grain-door which accomplishes all the objects herein set 'forth and which is entirely practical and e'l'licient in every particular.
I claim q l. A grain-door comprising a door-frame, an upper door-section pivotally slidable in Said frame, retaining-flanges near the inner edges of said door-section7 a lower door-seci and guide-bars -for the upper door-section adapted to form pivotal supports to said section.
2. In a grain-door, the combination with a frame, an upper door-section pivotally slidable in said frame, retaining-lianges near the edges on the inner side of said section, a lower door-section slidable in said flanges, and a supplementary door-section hinged to the roof of the car and adapted to engage the upper door-section.
3. A grain-door comprising a door-frame7 an upper door-section pivotally slidable in said frame and provided with a cut-away portion along its upper edge, removable panels covering said porti-cn7 guide-bars adapted to form pivotal supports for the upper doorsection, retaining-flanges on the inner face of the upper section, a lower door-section slidable within said i'langes, a supplementary door-section hinged to the roof of the car and adapted to engage the upper door-section, and means for locking said supplementary section to the upper section or to the roof.
In testimony whereof I a'l'liX my signature in presence of two witnesses.
JOHN JOHNSON.
