s claims. (or. los-.355) q Y This invention relates to freight car construction and with regard to certain more specific features thereof 'to box or house car construction and to improved methods of manufacture of the 5, same.

The invention has for one of its objects to pro-` Vide an inexpensive and durable box car divided by transverse partitions for the receptionand transportation of different lots of loose freight respectively in individual or distinct compartments, and having side doors for each compartment whereby a shipment may be loaded or'unloaded without disturbing the contents of any othercompartment. i

Another object lies in certain of the partition--A ing means being in the form of'doors displaceable when desired to enlarge one compartment by opening it to one or more of the others. In Va preferred form of the invention this object is 20, carried out by hinging the doors at the car sides so that substantially the entire transverse partition may be quickly removed when uniting the adjacent chambers or compartments;

Another object ofthe invention is to `provide 125. ar frame construction of improved type vwhich facilitates the operation of applying a cover or sheathing so that it will produce .a substantially flush exterior, lowering wind resistance and presenting a neatexternal appearance, and which o serves substantially in support of the partitions or the side doors, or both. e

'Still another object of the invention isl to provide a union of flanged or reinforced metal frame pieces to produce a sturdy frame for flush exfterior sheathing and the securing of partitions or doors, or both, if desired, and also to provide a novel method of uniting flanged or reinforced Vrnetalframe pieces at right angles to each other. Other objects will be in part obvious and in part pointed out particularly hereinafter,

rThe invention accordingly-consists in the various features of construction.combinations of elements, and arrangements of'parts whichwill be exemplified by the construction hereinafter set forth and the scope ofthe application'of which willbe indicated in the appended claims.

Fig. 10 isa fragmentary sectional view lof a portionof the car, showing the hinge connection 7 (L for the doors closing the compartments, and

\ Fig. 11 is a front elevation of the parts shown in Fig. 10. i Referring now more particularly to the drawingslvthe'f'car of the presentinvention comprises 75 an underframe having a center sill 10 formed of 'standard A. .RQ-A. sections 11 'and 12 connected by rtop and bottom cover plates 13 and 14, respectively; rIvhe lunderframe also includes longitudinally extending side sills which preferably are SJ commercially rolled ship channels each having a web 19 and inwardly extending upper and lower flangesl'l and 18, respectively.

Suitable bolsters and crossbearers (not shown) connect the side sills Aand the center sill and the side sills are suitably connected at their ends by end'sill membersyfThe end connectionmay be by channels similar to the side sills or by any otherjrolledA orplate section. The flooring for the car may beapplied over the side and cene ter sills' and the transverse end connections may befapplied overy the flooring. `As' specifically shown herein, the transverse connection between the ends of the side sills is an angle member 20 which overlies and is riveted to the top iianges Q5 l'flof the sills. 3 l

Cornerpost's `21 extend to the corners of an upper metal frame comprising longitudinal Z- bars 22 and Atransverse metal end members 23. -rI 'he corner posts comprise Wooden uprights 24 100 fitted in metal angles 25, the latter receiving marginal portions of exterior covering or sheathing 26; A facing stri`p2'? covers the edges of the sheathing at the corners.

Posts or-Vuprights 30 are spaced along the sides 105 and ends of the car. They are united with the side sills'in a novel manner whereby a strong union is effected quickly and conveniently and the main facing portions of the uprights are broughtsubstantially ush with the outer facey of the side sill web. 'Ilhese posts may be in any of a number of cross sectional forms, two suitable embodiments being shown in the drawings. Preferably each post has a facing portion 31, specifically a flange, and a reinforcing or strengthening portion 32 which may be in the form of a flange or web as shown in Fig. 5 of the drawings or may be a `pressed channel `33 as shown in Fig. '7 of the drawings.

In making the union above mentioned, upper inwardly extending flanges of the side sills are provided with spaced apertures 35 preferably of a shape and size corresponding to fthe shape of the post to be used in connectionl therewith, and also preferably lying wholly within'. the flange leaving the inner edge thereof'intact and continuous. The size and shape ofthe aperture is such that the end of the post'mayhave a sliding nt with the flange of the sill at the aperture. 'I'he end of each post is inserted'through the fiange of the sill at `the aperture preferably until the inserted lendcomes at or near the lower flange of the sill. The apertures are so vpositioned in the upper iiange of the sill that the facing 31 of the inserted portion of the post is brought substantially against the inner face of the web of the sills. Rivets 36 secure the facing portion of the post to theweb of the sill. The edges of the flange at the aperture serve as a means for supporting the two parts of the union in assembled position while the riveting operation is eiected, and also serve generally to prop the post and to an extent relievey the rivets 36 of shearing strain. t 'The posts 30 are preferably oifset from a point 40 inwardlly, that is, the inserted end portion of the post is set'in so that when the post is in assembled position the facing portion of the body of the post comes .substantially flush with the outer face of the sill web. The sheathing 26 is secured to the facing portion lof the posts 30 and may overlapvandubew secured to the web portion of the sills.v A n In Figs. 7 and 8 the post is shown asaI pressed metal member having afacing portion constituted by flanges 50 and 51. `Ihevstrengthening portion is in channel form as indicated at 33 having channel sides 52 and a web 53. The manner of offsetting thel vend and insertingit through the flange ofthe sill and securing it to the inner face of the sill web issubstantially the same as previously describedvin connection withthe form show n in "Figs,` 5 yand-6. v The upper ends of the posts arerlrivetedor secured in any Vsuitable way tothe metall-bars 22 of the upper frame and at the ends Yof the cars the posts 30 accordingto the present showing have their lower ends substantially abutting the inwardly extending lower flange of the angle 20. l

End walls 60, preferably of wood,4 abut the corner posts 21 and the end uprights 30. Suitable wooden iillers maybe flttedin the shoulders of the posts as indicatedat 61., Y

A series of transversepartitions are shownnat 64 extending between and securedto the posts on oppositesides of the c ar..` .Some of these partitions may be inr substantially permanent form as indicated vat 65 and jotherS my be in the form of pairs of hinged doors 66.` These kmay be of plate metal suitably reinforced and they arehinged at` 67 at the posts on opposite sides of the car. They are 4interitting at 68 where suitable locking devices may be applied if desired. i As shown clearly inV Fig. 1 of theY drawings, the hinged doors may be movable to opposite sides of the car so as to unite two compartments and enlarge the space to accommodate a larger shipment. The upper frame is formed with a roof 70 of substantially conventional style.

Door frames are formed in the car sides by certain of the successive spaced posts 30 together with the side sillsof the car, andangle members connected to the posts forming lin- `tels. 'I'he sides and ends of the car are comi pletely sheathed to the door frames, there being one of these frames at each side of the car for each of the compartments provided by the partitions 64.

Each door frame is'provided with a pair of doors 81 provided with hinge leaves 81h connected to hinge members 81a which latter are secured by rivets or other suitable fasteners to the posts 30. The doors 81 are, therefore, sturdily supported and may be swung together at the -middle of the frame as shown at 82, in which position they may be locked by any suitable locking device as indicated at 83. The arrangement of the side doors yand the partition doors is such that when two compartments are unitedA the partitiondoors may overlap or overlie one set of side doors but will in so doing clear the partition door well away from another vset of. side d oors which provides free access to the enlarged compartment, for loading and unloading purposes. Y t

The rolled sections constituting the side sills are not materially weakened by the apertures. The aperturing of the flange may be by punching or burning or the posts may be forced through the flange byvelectrical process. Several comparatively inexpensive methods are open to the manufacturer. Flooring 90 maybe laid over the upper sill flange and fitted neatly around the uprights.

A lining 91 of open slat work of wood may be continued around the compartment walls to prevent the freight from coming in contact with the sheathing or uprights and some or all of the compartments may be insulated and arranged for refrigeration. A
