Application January 7, 1953, Serial No. 330,030

Claims. (Cl. 268-44) My present invention relates to grain doors, and more particularly, to a novel pry board for use in connection with flexible grain doors in opening storm doors of closed cars.

As is well known, there is no purchase for a lever-acting tool when used in opening the storm door of a closed car in which the door opening is closed by a flexible grain door.

The object of this invention is to provide a novel pry board applicable to a car structure of a closed car on opposite sides of a door opening for use as a purchase in opening the storm door of the car, in which the door opening is closed by a flexible grain door.

A further object of my invention is that normally my pry board will be located in the car door opening in such a position as to be readily accessible for facilitating the opening of the storm door of the car regardless of whether said car is spotted in the open yards or against a. loading dock. In some instances however, especially when a car may be loaded with a commodity that may require sampling before unloading, my pry board may be located near the top of the flexible grain door, thereby permitting the sampler to place a ladder against said pry board and/or, if necessary, sit astride the same during the sampling process. My pry board by virtue of its shape and rigid construction will permit the sampler to perform these tasks with safety and from a relatively comfortable position.

To the above end, the invention consists of the novel construction and arrangement hereinafter described and defined in the claims.

In the accompanying drawing, which illustrates the invention, like characters indicate like parts throughout the several views.

Referring to the drawing:

Fig. 1 is a fragmentary elevational view of the inner side of a closed car in which the opening between door posts is closed by a flexible grain door, the invention being shown by means of broken lines;

Fig. 2 is a fragmentary elevational view of the outside of the parts shown in Fig. l;

Fig. 3 is a fragmentary view in section taken on the line 33 of Fig. 2, on an enlarged scale;

Fig. 4 is a fragmentary view partly in plan and partly in section taken on the line 4--4 of Fig. 2, on an enlarged scale, and

Fig. 5 is a fragmentary detail view partly in plan and partly in horizontal section taken on the line 5-5 of Fig. 3 and further showing a storm door and a lever, as shown, a crowbar.

The numeral 5 indicates a fragment of one side of a closed car having a door opening 6 between two door posts 7. The floor of the car is indicated by the numeral 8.

The door opening 6 is closed by a flexible grain door 9 fully shown, described and broadly claimed in my pending United States application entitled Flexible Grain Door ice the door posts 7 and pairs of cleats 10, are folded around the innermost cleats and said cleatsv secured to the door posts 7 by nails 10. The bottom portion of the grain door 9 is folded inwardly onto the floor 8 under a floor board 11 to afford a floor flap 9' and said floor board is nailed to the floor.

Referring now in detail to the invention, to wit: a pry board 12 which, as shown, is formed of a folded single sheet of metal and includes a body having a back member 13 and a front member 14. The pry board 12 is horizontally disposed and the metal at the top of the back member 13 is turned outwardly and downwardly on substantially a semi-circle 15 and thence the metal extends downwardly and inwardly to substantially the lower longitudinal portion of the back member 13 and forms the front member 14.

The metal at the bottom of the back member 13 is folded outwardly and upwardly to afford a retaining flange 16. This flange 16 outwardly overlaps the lower longitudinal portion of the front member 14- and holds the same in place. If desirable, the flange 16 may be secured to the front member 14 by welding, crimping or otherwise. The back member 13 is extended outwardly of the ends of the front member 14 to afford attaching end members 17 that overlap the door posts 7 on the inner sides thereof and is secured thereto by nails. Longitudinally spaced holes 17' are formed in the attaching members 17 through which the nails may be. inserted when driving the same into the door posts 7. It will be noted that one of the attaching members 17 is longer than the other to accommodate the pry board 12 to varying distances between the door posts 7. The pry board 12 is necessarily attached to the door posts 7 before the grain door 9 is installed.

Formed in the front member 14 at substantially its transverse center, is a plurality of longitudinally spaced holes 18, as shown, round. These holes 18 permit a leveracting tool 19 to be progressively inserted therein to engage the front member 14 as a purchase or base of resistance and with the tool 19 intermediately engaging the front edge of a storm door 20 as a fulcrum, the storm door 20 may be pried open by a step-by-step movement.

The outer side of the inner member 13 of the pry board 12 is transversely concavo-convex with its convex surface next to the grain door, and thus presents a smooth surface to the flexible grain door 9 so that said door, which is made of heavy paper or other suitable material, is not damaged by rubbing on the pry board 12.

While the drawing shows only one pry board, it will be understood that two or more may be used and if one is placed near the top of the door opening 6, its curved top affords a convenient seat for a man while taking samples of grain in the car.

While there are herein disclosed but a limited number of embodiments of the structure, process and product of the invention herein presented, it is possible to produce still other embodiments without departing from the inventive concept herein disclosed, and it is desired therefore, that only such limitations be imposed upon the appended claims as are stated herein, or required by the prior art.

What I claim is:

l. A metallic pry board for railroad boxcars having slidable storm doors normally closing the door opening lying between the door posts of said boxcar, said pry board comprising in combinationa tubular body portion that is vertically elongated in transverse section constructed and arranged to span the door opening lying between said door posts, said tubular body portion atforde 2,828,121 H p I ing vertically elongated inner and outer surfaces relative to the door opening, said surfaces of the body portion being longitudinally extended and flattened at each end thereof to overlap the door posts and thus afford a pair of members for securing the pry board to said door posts, and a plurality of longitudinally spaced transverse centered holes in said outer surface of the body portion to receive the end portion of a lever fulcrumed on one vertical edge portion of said sliding storm door whereby movement in a horizontal plane is imparted to said storm door by inserting the end of the fulcrumed lever successively in each next adjacent hole in the outer surface, which holes afford a base of resistance against the lateral movement of the lever.

2. The structure defined in claim 1 wherein the longitudinally extended members are provided with a plurality of holes for nailing the pry board to the door posts of a boxcar.

3. A metallic pry board for railroad boxcars having horizontal slidable storm doors, said pry board being constructed and arranged to span the door opening between the door posts of said boxcar, comprising in combination a vertically elongated tubular body portion spanning said door opening, thus affording transversely spaced inner and outer surfaces relative to said door opening, the upper portion of said inner surface being bent outwardly and downwardly to form said outer surface to substantially the lower longitudinal edge portion of said inner surface, thus affording an upper longitudinal edge portion that is substantially semicircular in cross section, said inner surface being longitudinally extended to overlap the door posts at each end thereof to afford a pair of members for securing said pry board to the door posts, and a plurality of longitudinally centered holes in said outer surface of the body portion to receive the end portion of a lever fulcrumed on one edge portion of the sliding storm door whereby movement in a horizontal plane is imparted to said storm door by inserting the lever fulcrumed on the vertical edge of said storm door successively in the next adjacent hole in the outer surface of the pry board to afford a base of resistance against the lateral movement of said lever.

4. The structure defined in claim 3 wherein the lower longitudinal edges of the inner and outer surfaces of the tubular body portion of the pry board are rigidly secured the one to the other by welding or crimping-- 5. The structure defined in claim 3- wherein the pair of members, and the hole-equipped outwardly bent and downturned outer surface are integral. with saidinner surface.
