yCAR-DOORv MECHANISM.
Application filed May 2,
To all 'whom t may concern:
Be it known that I, @LEON M. HANNA- Folin, a citizen of the United States, residing at Richmond, inthe county of Henrico and State of Virginia, have invented certain new and useful Improvements in CarlDoor Mechanism; 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.
Theinvention relates to door locking and securing mechanism for railway dump cars i and has for its principal object to provide a Cal new and useful construction whereby a swingingly mounted door may be securely held in closed position.
Another object of my invention is to provide a swingingly mounted hopper car door with a. reinforcing member, an end portion of which overlies the hopper side sheet and extends into the path of movement of the 'j door securing hook.
A still further object of the invention is to provide a swingingly mounted hopper car door with a hook engaging member, said member having a portion which is interposed between the hook and the adjacent hopper side sheet, and another portion ada tedto be releasably connected to said hoo r.
To these andl other ends the invention comprises the various elements and combinations of elementsv hereinafter described, the novel features whereof will be pointed out in the claims. 1
In the drawings:
Figure 1 is a side elevational view of a portion of a hopper car showing a hopper side sheet and a swingingly mounted door and illustrating the invention.
Figure 2 is a View in elevation of the parts illustrated in Figure 1, the direction of view being at right angles to the direction of View of Figure 1.
Figure-3 is a cross sectional view on the lines 3-3 of Figures 1 and 2, the direction of view being indicated by the arrows ad jacent the ends of said section lines.
Throughout the specification and drawings like parts are designated byv like referl ence characters.
While I have illustrated but one hopper' and the adjacent edge of the door, it will be readilyunderstood by those skilled in the art 1924. sei-iai No. 710,593.
that the construction is preferably dupli- Such con- 1 The numeral 1 designates the slopingv side sheet of a hopper, and 2 a swingingly mounted door adapted when in locked position to close the opening of the hopper. Said door is preferably provided with downturned marginal flanges 3 and secured'to Y the door in any desired manner is a stifening member or spreader bar 11. The said spreader or stiffening member t may be of any commercial rolled section and is illustrated herein as of angle bar form having the flange 5 thereof secured to the lower face of thevdoor 2 by a plurality of rivets or bolts 6 and having aflange 7 arranged substantially at right angles tothe plane of the door 2. Adjacent the free edge of the door 2y one of the marginal anges 3 isy interrupted `or cutaway, as at 8, to permit the passage of the. end portion 4ta of the spreader 4, said end portion being preferably bent at an angle to the door 2 so as to overlie and pret-` erably to extend parallel with the side sheet 1 of the hopper. i
Connected to the hopper side sheet 1 is a bracket 9 which may be provided with a plurality of perforated vhubs 10, 11 and 12, 1v
through which the securing means or rivets 13 may extend. A door securing hook 14; is preferably pivotally mounted on the hub 12 by means of the rivet or fastening means 13 and pivotally secured to the hubs 10 and 11,-
also preferably by the rivets 13, are eccentric cams or dogs 15 and 16, the purposeof which will hereinafter be described.
At a suitable point in the iiange 7 of the end portion lla of the spreader I provide a slot or recess 17 adapted to receive the bill 18 of the hook 1st so that the said hook when seated within said slot or recess'will support the door 2 in closed position. The
By providing a recess 17 in the flange 7 to receive the hook la all danger of the disengagement of the hook and door by weaving of the car under-frame is avoided.
I claim:
