DOOR FOR RAILWAY BOX CARS.
Patented May 17, 1870.
CHARLES BARKER, 0F KNOX COUNTY, ILLINOIS, ASSIGNOR TO'HIMSELF AND T. o; THOMAS; or SAME PLACE.
Letters Patent No; 103,126, dated May 17,1870; imztcda t ed Mat 13.187}
IMPROVED noon r03 RAILWAY Bot-cans,
The Bbnedui'e referie'dto fzi'thesc Letterepatent'ahd makingpart of the same.
To all whomthinly concern: I
. Be it known that I, Cumulus BARKER, a citizeri'of' Knox county and State of Illinois, have invented a new and improved Grain-Door for Box-Oars and I do hereby declare that the following is' a clear, full, and exact description of the same, reference being-had to the accompanying drawings, in which Figure I is a front View of my improved door. Figure II is avertical sectional view through the lines a: m.
Figure III is :1 view'ot the door detached from the FigureIV iS a front-view of the car-door, wit'h my grain-door open. I w w l The nature of my invention consists in supplying-a door for cars designed for the transportation of grain inbulk, and so constructed that it can beconveniently opened, and whenopen will not be liable to be lost or broken up, and" when only partially open or thrown up it will still retain its hold, and withstand the outward pressure of the grain, thus overcoming the inipracticable features of doors now in use. Y To enable others skillediu the art to make nd use my invention, I will now proceed to describe its con-- struction and operation, as I have carried it out'.
A is the side of a box-car constructed inthe usual way. I
B is the grain-door, pivoted at b, and so inclined at the opposite end 0 that each corner will he an equal distance from the pivot. This peculiar shape of the door'euables it, when partially thrown up, to retain its hold, and at the same time withstand the outward pressure of the grain.
When the door B is in position, as in fig. 1, it fits snuglyin the grooves m m,"so asnot to allow thegraiu to enter them.
The opening 11 in the lower part. of the frame A and in the rear of the door 13 is for the escape'of any grain which may chance t6 enter the groove. or slot designedfor the reception of the door when thrown up, thus securing at all times a free motion in the door.
There is a lining completely covering the iusideot" the scetion of the car in which the door is placed, and fitting so closely that grain cannot enter the cavities or grooves when the door plays.
0 is a semicircular slot in the frame-work A, through .which to reach the door B when thrown back in an open positionand it'is required to be closed.
What I claim as my invention, and desire to secure by Letters Patent, is-
. The revolving door B, when applied to a railroad box-car, substantially as and for the purpose described.
. j Also, the revolving door B, when applied to a rail- Also, constructing a-revolving grain-door for box cars with the outer points of the door equidistant fromthe pivot on which it turns, substantially as and for the purpose set forth. a
