ing is a specification.

In vconliection,withthe walls of railway' box-cars it is desirable to provide some simple and efective means. for maintaining.

` .tight the joints or seams between the boards or planks, especially when the wall is com`- posedof but a `single `tlfiiclrness' of such boards. it is well 'known' that-suchjboards or planks have a tendency to shrink, diminishing .their transverse dimension, and obviouslyvwhere but a single thickness of such boards is used in a car-body wall some tight wise a lading' composed of small particles, such as grain, would leak, and the outer air and moisture would have a. more or less freepresent invention is to provide an econom ical and efficient, means for accomplishing such a result.

Several desirable embodiments of the invention, have been illustrated 'in the accompanying drawings which form a part of this. specification and throughout the various views of which like reference characters refor to the same parte.

in Figs. Band 9; and Fig. ll is a cross-sec tion through a car-side, showings/,till another style or form of tightening means. As is usual in car-body constructions, th

car .has the ordinary channel center-sills 2G,

20, channel side-si`lls2i, 2i, to the outer.

faces of which` are riveted the lower ends oi vertical posts 22 Iand 23, which. may be of any of the ordinary forms of sections,

Vdiagonal braces 24; being also riveted or otherwise asteneal to the side sills. At the tops .of the'car-body sides I position a pair of roof beams 25, 25, which may, it desired, be of channel shape, the upper ends oi' the .posts 22 and 23 and the braces being riveted or bolted thereto for an object per fectly obvious. v

Each car-side is composed of a pluraiity of boards or planks 26, tongued and grooved in any approved manner, and securedto the inner faces or' the outer posts and braces 22, 23 and '24 by means of indicated in Fig. 3, passthroughgsmal slots 28 in the flanges of these" outer metallic members. The top board or plank, 26 has dis posed on its upper edge a .metallic strap or bolts 27, which as is'` bar 29,1 with which the lower ends of a plurality of tightening screws 30 coast, such screws passing through threaded holes in.v the lower inwardly projecting flanges of the,

channel' roof-beams 25. It will therefore be obvious that if the jointsor seams between theboards have a tendencyto open up, due

to the shrinkage or' the lumber, they may be tightenedby .loosening the bolts 27, turning the screws 30 so as to bring vertical pressure to bear upon the boards and then ti btf eningthe bolts 27 to hold the boardsain t ieir` new relation. in order to prevent the en? posure of the screws 30 Aand other parte to theelernents, l fasten to the outer face of each rooibeani a. metallic apron or .shield`32, whiohprojects downwardly so as to overlap 'the top board, as is shown in Fig. Ai. Also,

in order to strenothentheflange 3l, the beam 25 may be providedwith a plurality cia strap braces 33 rivetedat their upper ends ati to the web of the beam, and at' their lower ends'at 35 to the beam flange. These braces may or may not beused, as occasion. dief mande, and for that reason they `are vnot showninFigQ. l Reterrin now to Figs. 5 to 7, inclusive, it

iet."

-will be Vnoticed that the construction is eizvactly the same as that--ofFigsl`to`4,

clusive, eXcept with respectvto the apron Vori metallic shiel'd 32, which in this new embodiment is replaced by a substantially inverted U-shaped member 36 riveted tothe lower face of the bottom flange of beam 25 and straddlingthe top yboard or\ plank 26, its opposite marginal -flanges overlapping s uch board, as is clearly indicate'din Fig. 7. In-

stead of using' a .longitudinal bar 29 von the top edge'of theupperboard, washers or on the top-edge .ofthe upper `-board I26, and extends upwardlythrough 'a hole 40 in the lower flange 4 1 of a'channel.roof beam-42 the hole Ibeingslightly larger than the screw,

.small plates 37 may be employed to prevent the lower end of the screw from ineffectively pressing vinto the comparatively .soft wood.

Looking nowat Figs. 8 to IQ-inclusive, it willbe observed thateach screw y38 bears at its lower end on vva blockerplate 39 disposed asis clearly shown, Riveted at 43 tothe outer face of-,beam 42 is a depending apron ,o'r

I b ack depending wall 50 n adapted to bear.

shield: 44,l which may-be y inwardly bent sli htlyat 45, if desired, and on the screw 381 be ow the flange '4l I employ an angular. nut 46, `through thej screwftlireaded aperture of whichthe screw48 passes. It will therefore be apparei'it that las 'the screw 3 8 is turned by means of a wrenchapplied toits squarehead V47, pressure is brought to bearon the boards' ofthe side-wall 'so as'to'close the joints be tween'them. In this instance' the screw.-

threaded'.liol'e' .of`the nut or blockl 46'is em? ploye'd for this tightening effect ratherthan `using.' a screw-threaded aperture in the flange ofthe roof-beam, and by employin a block 4 6jof desired thickness an vunusual yl strongand veffective a plian'ce of this character can o prevent thescrewg 38 from acmdentally turning, I "may use 'alockiiig" be rovided.-

member 48 having a top wall 49adapted to reston the top of the screw and-having 'a -a ainst the inner face ofthe beam 42, and aso having two side walls/51 intended to straddle the screw-head so as to prevent its unintentional turning. To remove this screw-lock so as to permit 'rotation of the screw, it' is merelyraised, from which elevated position it can be readily taken out of place-5 "and to applyit in-e'ective engage- 'ment with the'screw-head, it-is merely necespreviousinstances, vif -desired, by a saryfto' slip-it over such head into the positionV of Fig. .9. In this instance the flange 49 may be braced and strengthened as in the lurality of strap braces 51, any number of Iwliiich may be employed, vpreferably adjacent to thcscrew, as shown in Fig. 8.

Another Wa of arrivmg 'at substantially the same regu t is indicated in Fig, 1l, in which casethe channel-beam'52 hasriveted thereto an outside apron' 53, bent as shown so' as to overlie both' the bottom and upper vfaces of the screw. 55 has fitsthreads coa'cting with the threadedaperture extended not only throughthe flange :54, .'but also through the two thick-I nessesl of the apron 53 which straddle the `number of lthreads-for the proper engagement '70 ilangefL In this way a hole with a sufficientV` of the screw is readily secured, the bottom end of such screw, as vinthe previous instance, bearing on a metallic strap 5G on' the top edge of the upper board 2G, or, if found more feasible, this strap may be replaced by metallic blocks, as shownin 'F ig.- 9, for instance.

In all these species it will .be observed that by tightening the screwsprovidcd for that purpose the shrinkage in .theboards` may be compensated for so as to keep the walls, either side or-end, of the car-bodyclosed. It will to produce, simple in construction and readilyo'perated. By using a considerable num-v ber ,of such screws throughout t ie length of thecar, as shown in Fig.- 1,'any inequalities readily overcome because of the-individual adjustments which the screws maybe given.

- This invention, as will be readily understood by those skilled in the art, is suscepftible .of a considerable number of embodi ments, and for that reason I do not wish to vhave it understood that the invention is l-iniited to the precise embodiments herein indicated.

1 ,Many minor mechanical changes may be made, inthe structures without departing from'lthe heart and essence of the invention vand without the sacrifice of any. of its aclbe apparent alsogthatthel various means which I have herein described yin detail for :securing the ob]ects fsought are economical in the boards or inthe shrinkage may be tween said boards, substantially as de scribed. l
