To all whom tmay concern: i

Be it known that I, ALLEN E. OsIRANDER, residing at Ridgewood, Bergen county, New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in Car-Underframes, of which the following is a full, clear, and eX- act description, such Yas will enable others 4skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the' invention, though itl is to be understood that the invention isnot limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a plan view showing the arrangement of the parts of an underframe conforming to the present invention, the floor sheets, transversely-.extending splice plates, the., bolster cover plates and the center sill cover plate, parts of the center sill cover plate being broken away, and the left-hand portion of the un derframe of this figure being separated to show the manner of connecting the end por# tions with the middle portion of said underframe.v Fig. 2 is a sectional view, the

section being taken on line 2&2 of Fig. 4.-

' Fig. 3 is a longitudinal sectional view, the

section being taken in two `planes indicated bythe line 3-3 of Fig. 4. Fig. l is a repro-l duction on a larger scale of the right-hand end portion of'Fig. 1, with parts of the floor plates broken away'and with portions of the center sill and side sill arrangement shown in section. Fig. 5 is a side eleva-- tional View of the structure shown .in Fig. 4. Fig. 6 is 'an end elevational view of the end sill of a car. Fig. 7 is a vertical sectional view, the section being taken on line 7-7 of Fig. l, that is at the dooropening Fig. 8 is va similar sectional view, the section being taken at 8-8 of Fig.

1, that is between the door opening and the' bolster. Fig. 9 is-a sectional view the section being taken online 8-8 of Fig. 1 through' the side wall, with the angle '36 comprising apart .of the side sill associated with the side wall 55v riveted to an out-v A standingflange 56 ofy a side body post 31.

'Fig 10 'is a fragmentary elevational view showing a part of the car at'and near the door opening.

The form 'and location of the several parts entering into the car forming the subjectmatter of this application will be hereinafter more fully described.

The principal object of the invention is to produce an underframe to be used in box and other cars adapted for usev on railroads where it is finally erected, comprising principally commercially rolled members which areeasily obtained in the open market for use in the event of repairs, and with the parts enteringinto the structure so arranged and proportioned that the underfrarne may be temporarily assembled in the shops of the car builder for inspection, after which it maybe separated into a multitude of com'- posite units, which are so arranged that they may be packed for shipment in the holds of seagoing vessels for transportation to the country where the cars arev to be used, and for transportation, if necessary, in detached composite units for land shipment to the point of final erection and service.

It is well known that a la-rge number of rivets can be driven either by machine or otherwise in the shopof a manufacturer properly equipped for this service in a more economical manner than such rivets can be the shops of the car builder, where .only

Patent-ed Aug. 10, 1 915,

hand-operated tools are available. In consequence' of this, it is one of the objects of the present invention to assemble the composite units in the shops and there drive as many rivets as possible consistent with the subsequent manipulation of the parts or fashioning of the car where it is to be used.

It is practically impossible to load into the hold of a vessel an entire underframe.

adapted for service on commercial railroads,

and lwhere kthe car parts must be shipped overland-prior to the laying'of tracks, it is evident that: they must be transported in fragments las smallas'is consistent with the structure to be finally produced.A Tov that4 end I have designed a car underfram'e consisting of three major divisions.

Referring particularlyto the underframe construction, it will be observed that the center sills l are formed of commercially rolled channels, which are spliced to, the draft sills 2, which they overlap, by rivets 3' projected through the Websfof the center sills and the ,draft sills. The draft 'sills are pressed channel sections with their flanges projecting in a direction opposite to that of the center sills, so as to bring the web plates of the draft sillsl and-center sills together, as best shown inthe sectional vie'wFig. 2. u

In transverseahnement with the sphce'of the center sills and draft sills, the principaling from angles. 7, body bolsters'S, comprising pressed di'aphragms or rolled structural members, or cast members,.as may `be def sired, extending from' the center sills and connected with "said angles 5, with which are associated'diagonal braces 10, which extend from the connection of the bolster with the center sills diagonally outwardly to theeorners of the car, all of the members of the end section except. angles 59 being united b v the floor plates 12, which floor plates are riveted to the inwardly -extending'flanges oftheanole, to the top flanges of the draft sills, to the inwardly-projecting flanges of the end sill, and to the horizontal lianges Vofthe diagonal brace langles 10. Over the floor above the bolsterthere is provided a topbolster cover plate 13, which unites the parts of .the-bolster projectinglaterally from the draft sills and" serves as a reinforce therefor. The bolster is preferably provided also with a bottom tie plate.. 14 forwell un.- derstood purposes.

Between the end sections just described, the central-or intermediate portion of the underframe is formed with floor sheets- 15 and 16, v'which extend from thel sides of the cartoward. the lcenter line sufficiently far to overlapthe topl flanges of the center sills, with 'which said iioor plates are connected by'dircct rivet connection, which is ,supplemented by a longitudinally extending center sill cover-plate 17, which extends continuously from' the rear edge of one bolster cover plate 13 tothe corresponding edge'of the opposite bolster-cover plate 13 at the opposite end of the car, and it is to 'be noted that 'the -floor Aplat- esl 15,and 16 and thecenter sill cover plate 17 serve as an additional means for splicing or connecting the draft sills to the center sills before referred to, as said floor plates and sill cover plate cover the lapping portions of said center silll and draft sill meinbersland-Qi The floor plates at the ends of the middle portion of the underframe overlap the side angles 4 and 5, and serve as an additional reinforce at that connection, this connection or splice beingsupplemented by the angle plate 6,' before re-` plates' 12, said4 plates are connected to the next adjacent plates by means of commercially rolled angles 21. (See Fig. 3). The horizontal legs lof these angles are riveted to the'loor sheets 15,' 16 and 12, and are closely juxtaposed, and the vertical legs of said anunit-ing said .angles'and` through said angles uniting the floor sheets before referred to.-

Ait other points, if desired, the abutting edges of sheets 15, 15 and y16, 16 may-be connectedvby splice plates overlapping the meeting edges of such floor plates. At still other points, angles 21 may beused singly, instead of in pairs,and be attached by connection angles to the side and center sills to act as floor supports. 4 j I ln preparing the underframe for shipment it is advisable to divide it for convenience of handling in such. a manner that the weight ofthe parts. isas nearly equally dis tributed as is consistent with subsequentrei assembling, ,fand for that reason 'the draft sills-are permanently attached to the bolsters in'- the shop, said .draft sills extending Arearwardly of the holsters. that is toward the middle of the lengthof the underframe and far enough' baclrto provide a long splice where the center sills lap andare connect-- ed thereto.

. Thebolsters are necessarily heavy, as they form the principal supporting members of the underfi-amel` and it is desirable to connect the end silland the end portions of the side sills and the draftsills together, hence it is advisable to.l connect those ,parts with the bolster b v means` of the floor plate 1Q and top bolster cover plate 13, and ship the 'fragmentary end portions. such as are shown detached at the -left of lig. 1, b v themselves, while the remaining underframe portion.l comprising the center sills, center sill cover plate, floor lplates intermediate the bolsters and the fraglnental side sill portions shown in Fig. 1 as a separate unit.

For the purpose of reinforcing the underframe at the door opening, l have arranged the center fioor plates l5 and 16 somewhat wider than the plates l5 and 16, said plates l5u and 16u extending bevond the side sill angles 4 to form threshold plates','\vhich are stifened and reinforced within 4the zone of the door opening by relatively inverted U-shaped pressings i2, the vertical legs of which are connected by horizontal rivets with the vertical legs of the angles l, so as to provide proper support for said threshold plate portions of the plates l5a and 16, and the end-portions of the parts -l2 are connected by angle brackets -ll with side stakes 3l, which are commonly used in the body portion of a car.

As the depending vertical legs of the angles .l lap the angle 36, it is necessary to provide a filler-ll', which extends substantially the length of the underframe, except Within the door opening, thereby providing a reinforce for the side sill, Which side sill comprises the angles l and 36 and said filler plate li', except at the door opening, Where the inverted U-shaped plate #l2 takes the place of said iiller i?.

The angle 36 extends continuously, except as hereinafter noted, from end to end of the undert'rame and, considering the structure herein disclosed, said angle 36 is a necessary part of the underframe as an element of the side sill.

lVhere the underframe of the present invention is lto be used with a if .1t car, it would probably be differently divided, but as the underframe of the present invention is intended to be used as a part of a knockdow-n car comprising the subject-matter of my application for Letters Patent filed July S, lillLSerial No. 707,592, l prefer that the angle 36 shall be attached to and be removable vvith the side. `Wall of such car, and comprises two longitudinally extending sections ivhich abut at the middle of the door opening andare there connected and spliced b vmeans of' the inverted U-shaped pressing i2, before referred to.

In addition to the plate i2, the angles 36 arespliced by a supplemental rolled angle gil', shown in section in T, which is`at- -tached to the vertical and horizontal legs of said angle 36 and extends across and for some distance beyond said door opening.

llhatl claim is:

l. ln combination, a intermitted lapping and connected parts and a side wall terminating in a rolled member lapping the intermitted portions of said side silland being connected thereto to connect the same.

2. 4In combinatiom'a plural part side sill formed of flanged members having an upper flange inwardlyidisposed and a body post secured to and connecting said flanged members.

Copies of this patent may be obtained for side lsill formed of five cents each, by addressing the formed of flanged members, a body post so cured to and connecting said members, are inforce member connected to one of said members and a floor sheet extending` over said sill and said reinforce member.

l. In combination, rolled flanged center sills spaced apart, a bolster, spaced flanged draft sills extending through said bolster lapping said center sills and being secured thereto and a longitudinally extending Genf ter sill cover plate riveted t0 the flanges 0f said draft sills and center sills-within the zone of4 overlap thereof.

5. In combination, side sills built up of longitudinally lapping and connected flanged members, spaced center sills of flanged members, floor plates connecting said side sills and center sills and center sill cover plates lapping said floor plates and center sills and being riveted to both said floor plates and center sills.

6. In combination, side sills each built up ot' lapping oppositelvv disposed angles, rolled flanged center sills, flanged draft sills 1apping said center sills, floor plates connected witlntlie upper flanges of said side sills and with flanges of the center sills and longtudi nal center sill cover. plates lapping and conF nected to said floor plates. i

7. In combination, built up side sills comprising pairs of longitudinally lapping and connected rolled flanged members, a built up end sill, a bolster connecting said side sills, spaced draft sills connected to said end sills and said bolster, a single floor sheet connecting all of said members and spaced center sills lapping and' being connected directly with said draft sills.

8. In combination, an underframe part adapted to be shipped asa unit comprising built up side sill parte, a built up end sill, a pair of spaced draft sills and a built "up bolster all united by a single door sheet and a bolster top cover plate riveted to said bolster through said floor sheet. o

9. A built up underframe comprising rolled flanged members held in position by floor sheets riveted thereto and comprising built up side sills, in combination With a side Wall terminating at its lower side in a rolled flanged lmember lapping and being connected to said side sill.

In witness whereof I have hereunto set my hand in the presence of two Witnesses.
