To all whom; it may concern:
Be it known that 1, SAMUEL MANUEL, a subject of the King of Great Britain, residing at Saltcoats, in the Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in Grain-Car 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.
This invention relates to improvements in doors for grain cars.
One object of the invention is to provide a sectional door formed of a plurality of independently movable plates which are capable of being nested in a suitable bracket above the door.
Another object is to so form each of the sections of the door that they can be readily grasped to be moved into either closed or open position.
Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings. 4
In the drawings: Figure 1 is a front elevation of the door showing the same in closed position Fig. 2 is a similar View showing the door partly closed. Fig. 3 is a vertical section on the line 33 of Fig. 1. Fig. 4 is a perspective view of one of the plates removed.
Referring particularly to the accompanying drawing, 10 represents a pair of slideways mounted on the sides of the doorway of the car, the upper ends being curved upwardly and inwardly, asclearly shown in Fig. 3, and secured to the inwardly extending brackets 12 above the doorway. The lower portion of the inner end of eachof the slideways is bent to form a recess or bracket 13. A plurality of elongated metal plates 14 are disposed crosswise of the doorway and provided with a slightly twisted longitudinally extending reduced end portions 15, these end portions being slidably disposed in the slideways 10 as clearly shown. The upper longitudinal edge portion of each of the lates is bent outwardly at right angles to orma flange 16, while Specification of Letters Patent.
Patented June 22, 1915.
Application filed April 10, 1914. Serial No. 831,092.
the lower edge portion of each of the plates is bent inwardly at right angles to form a flange 17. Each of the slideways has an attachingflange18, and between this flange and the body of the slideway is an inset an-' of the plates below. The slides haveftheir grooves of such width that the twisted portions 15 will easily move up and down, but
not wide enough to permit them to pass thev extensions of another plate.
When the door is in full open position all of the plates are nested in superposed relation within the support or bracket 13.
When in this elevated position, and it is desired to close the door, the innermost flange 17 can easily be graspedto lift the topmost plate up into the curved parts of the slideways. It will also be noted that the upper flanges 16 provide ready finger-holds to raise and lower the plates in the slideways. Thus, at all times, the plates can be quickly and easily grasped for manipulation.
What is claimed is:
The combination with grooved slideways mounted on opposite sides of the car door, of a plurality of metal plates disposed between the slideways, and each having reduced end portions disposed in the grooves of-the slideways, such reduced portions being deflected so that they lie in a common plane while the bodies of the plates lie in parallel inclined planes, the lower edge portion of each of the plates being bent inwardly at right angles to the plate and the upper edge portion being bent outwardly at right angles whereby convenient'finger holds are provided to facilitate the manipulation of the plate, said plates being adapted to be moved-to the tops of the slideways and into a nested pile.
In testimony whereof, I aflix my signature, in the presence of two witnes es.
