To all whom a ma 0mm,

Be it known that I, WILLIAM E. FoWLER,

- a citizen of the United States, residing at construction of box cars,

Montreal, in the-Province of Quebec and Dominionof Canada, have inventedcertam.

new; and useful Improvements in Box-Cars, of which th effollowing is a specification.

- This invention relates to a 7 novel con structionsof box cars, and has for its general object to simplify, lighten and 'cheapen the p and more particu side walls and floors thereof, by

larly the with the necessity for doubledoing away Y sheathing at present extensively employed,

especially in grain cars; a further important object being'to provide a means for coun-- tel-acting the efiects of shinkage and preventing the formation of cracks at the points between the invention employs to some extent the general constructional features of the side walls of wooden gondola car bodies in which are used horizontallyarranged superposed sideplanks bolted the side-sills,

to vertical stakes mounted on with side-plank tie-rods and tie-straps passing through or bolted across the series of side-planks.

In carrying out my invention as ap lied to the side walls, I employ as the sole fi ling elements or sheathing thereof a series of superposed horizontally arranged narrow side-planks preferably formed with overlapping oflset-or' other similar matching joints, which side-planks are bolted to metal stakes disposed at intervals along the outer sides of the walls; while, as a means for drawing the side-planks together to prevent the for- I mation of cracks at the joints as well as to counteract shrinkage of the side-planks and render the oints tight, I employ a novel device in the nature of a tightening-strap, which, in its preferred form, is characterized by a hook or equivalent device at its upper end which engages over the upper edge, of one of the series of side-planks,-preferably the topmost, and a threaded lower end which passes through an anchorage below the side wall and receives a nut for securing and adjusting purposes.

In the preferred form of the invention herein illustrated the side-sills of the carbody are of the inwardly-facing channel form, and the lower threaded ends of the ti ghtening-straps pass through the'car-fioor and the upper flanges of said side-sills and are secured to the latter by nuts on their planks;'and to these ends my I i 1 l lower ends. same general principle of construction is involved in the application of the invention to the tl oors,'a single thick- .ness of planking being employed, the planks having matching o'r offset oints, and being secured to the-floor-sills by bolts provided with sufficient lateral play insaid floor sills to-allow-the entire series of floor-planks to be forced together edgewise to close any cracks that may occur at the joints between adjacent planks ,due to shrinkage or other causes.

My invention will be readily understood I when considered in connection with. the'aecompanying drawings illustrating simple mechanical embodiments thereof, in which;-

I Figure 1 is a fragmentary side elevation of one end of a box car showing myinvention applied thereto. Fig. 2 is a vertical cross-section through the ca'r-bodyon the line 22 of Fig. 1. I Fig. 3 is a fragmentary transverse section, enlarged, on the line of Fig. 1. Fig. a is a view similar to Fig. 3 on the line l4 of Fig. .1. F ig. 5.is a vert1cal sectional detail illustrating the manner of securing the stakes to the sidewalls to permit a tightening of the joints of the latter by the adjusting device of my invention. Figs. 6, 7 and 8 aretop plan details 1n the plane of the upper edge of one of the car sides showing various forms of standard rolled steel stakes that may be employed in connection with my inventlon. -Fig. 9 is'an enlarged plan view of a portion of the car floor. Figs. 10 and 11 are sectional views on the lines 1010, and 1l-11, respectively, of Fig. 9, looking in the directions indicated bythe arrows.

Referring to the drawings, 10 designates the floor, 11 the plates, 12 the carlines, 13 the purlins, 14 the roof boards, and 15 the running-board of a box car. Beneath the floor 10 are the center-sills 16 herein shown as a pair of outwardly facing steel channels, and side-sills 17 herein shown as a pair of inwardly facing steel channels of contracted width at their end portions, as shown in Fig. 1, and intermediate longitudinal floor sills 8 herein shown as of Z-beam form. Connectplanks are secured to a series of upright stakes, which latter are-bolted or riveted at their lower ends to the outer sides of the side-sills 17. These stakes are preferably. steel bars of standard rolled forms, any of which having a member parallel with the plane of the side-planks and another memher at an angle thereto for stifiening purposes may be employed. In Fig. 1 I have shown at an angle-bar form of stake, at 20 a T-form, and at 20 a channel-form. In Fig. 6 I also show an I-form 20, in Fig.

7 an angle-form 20 provided with a bead on its outer edge, and in Fig. 8 a Z-form at 20". These stakes, as shown in the detail view, Fig. 5, are secured to the side planks by bolts 21 which pass through'short vertical slots 22 in that member of the stake lying flat against the side-planks and through improved tightening-strap, either or both of which may be employed to satisfactorily effectuate the purposes of the invention. In'

- Figs. 1, 2 and 3 I show a tightening-strap a of the latter, an is 7 end with an outwar 24 that extends transversely of the side planks, lying snu ly against the inner sides provided at its upper ly and downwardly turned hooked portion 25 that'engages over the uppermost of the series of side-planks 18. The lower end of this tighte g-strap isrounded and threaded, as shown a 26, and extends through a hole in the car-floor 10, and, where used in association with a steel side-sill having a laterally projecting upper flange, such as the channel-sill-ll, likewise extends through an aperture in said upper flange and is secured by a nut 27 beneath said flange. The other form of tighteningstrap illustrated in Figs. 1 and 4 differs from that above described in that the main body portion of the strap is formed as a complete elongated loop 24 completely embracing the series of side-planks at the top, bottom, and on both sides, said tightening strap being secured at its lower end by the means and in the manner shown in Fig. 3. These tightening-straps may be applied to the'side Walls of the car at points between adjacent stakes, as shown at the center and at the right in Fig. l and in Fig. 2;'or, they may be ap-.

plied directly opposite a stake, as shown in Fig. 3 and at the left in Fig. 1; in which latter case the longitudinal member or members of the strap that engage the side-planks are, like the stakes, provided with narrow vertical slots 28 to receive the bolts 21.

From the foregoing it will be evident that by screwing up the adjusting nuts '27, the tighteningstraps are drawn downwardly,

slotting of the tightening-straps 24, where located in the transverse planes of the stakes, .likewise permits such downward movement of the tightening-straps in the adjustment. This adjustmentnot only produces a. tight construction of side wall in the first instance, but,in case the side-planks shrink, thus tending to open the joints between them, such open joints can be easily and quickly closed by further adjustment of the tighteningstraps. v

Between the stakes maybe 1 applied the usual oblique braces 29 herein shown as of angle-bar formation secured to the horizontal planks of the sheathing by-bolts 30; and to accommodate the contracting movement of the sheathing, the holes in the braces accommodating the bolts 30 are elongated vertieally, as indicatedat 81 in Fig. 1. In this connection it may be noted that, since the 18 under the action of the tightening-straps is greatest at the top and diminishes to practically nothing at or near the bottom of the wall, the slotting of the stakes and braces will be greatest at or near the upper end and may diminish and disappear at or near the. lower end of the wall. In Figs. 9, 10 and 11 I have illustrated the application of this principle to the floor construction of the car, although I have not shown the latter as equipped with the tightening-straps, since the tightening effect may be otherwise secured. Referring to these figures, it will be observed that the individual planks 10 of which the floor is composed rest transversely of and upon the upper horizontal flanges of the longitudinal floor bars 8 and side sills 17 and are secured thereto by means of bolts 32, which pass through slots 33 formed in and longitudinally of the upper flanges of the floor beams. The planks are formed preferably with matching offset joints 10, as shown; and, in the event of any shrinking of the floor planks such as would produce an objectionable crack between them, by simply slightly loosening the nuts on the securing bolts 32 and applying a crow-bar or similar tool to the end lanks of the series or between any two oii the planks, the latter may be forced into snug edgewise engagement, closing up any cracks that may occur at the matching joints; while the crack at the point where the tightening tool is applied may be filled in and closed in any suitable manner.

My invention is particularly useful in cars intended for the transportation of grain; and it is noteworthy that the tighteningstraps not only serve at all times as a means extent of downward movement of the planks Y intended to include the shorter sides or ends of the car, as well as the longer or longitudinal sides thereof.
