ToaZZ whom it, may concern:

v -GEORGE G. FLOYD, a citizen of the United States, residing at Granite Cit in the co'untylof Madison and State of llhnois, have invented certain new roveI-nents' Car-Truek Side following is a specification.

-.My invention concerns QIBJIWH. cartr'ucks and has for one of ItsOb ects t construe- 1 v .tion-of such .trucksin such a mannerthat if the )urm11-boxes become damagedjor' injure they may-he readily replaced; that the wheels and -ax1es n1ay'.be easily rolled side-frames; that this plished in a truck necti .there out. of the truck by Slightly jacking. up the result canbe acconr, which the side-frames aretransversely connected together by conbarsor beams fix d riveted thereto, ing'no I-cutting rivets required when'the .-journa1 -boxes or axles and wheels aretaken out of place; and another object of the improved construction being to so 'makethe partsthat .the -journal-hoxes can" automatically adjust gth'emselves Jongitudi j jnally of the-axles,

In this embodiment of the invention the -side-frame 10, which may be of any preferred or desired end the depending spaced portions 11' and 12 between which the journal-box '13 is accom'modated, the latter having on each side a pair of ribs -14, 14stradd1ing the two parts 11 and '12. ,It will be ap arent, therefore,

- by these .11 and 12 which extend down overfjthe box approximately one-third the 'c'iepth ';:-of--the ..1atter."

In. order that these journal-boxes may" have a slight rocking orswinging movement secure-a uniform bearing throughout --'the iournal -boxes of the axles lfiy-thatpart of t two depending embracing- 5ortions' y of the side-frame, whereby to 35 length of the bearing brasses, not shown, on I, ithe e sidefrajme 10 above the journal-boxis so shaped as to provide-a. longi-tlzdinal" groove 16 curved in cross-section and lad-apt;

ed to accommodate and receive a -curved,

centrally-apertured rib '17 ..extended across the top face ofthe journal-box and-{forming an integral part thereof.- The curvatureof theb'otto'm of the groove 161s of somewhatgreater radius than that of'the rib"17,'that the j G111I1&1 -bOX,' evefi 'mi't-ted thereto "from the side-frame, may, rock or swingfslightly to accomplish the re-.

this. may be carried out in the of truck, I provide the outstandlng flange 18-.

of the part 11 with an enlargement orbo'ssi r 19, which hasi extendedhorizontally therethrough a holehaving a cylindrical inner i with the journal-box and so that ituwill be -2 unnecessary to drill or finish the holes portion" 20 which communicates with an outer conical or flaring part 21. The'flan e '22 of the :part or portion, 12- of thesi eframe is also equippedswi'th an enlargement) or boss 23 apertured in 'alinement'wlth "the holes 20 andv 21, .such aperture having 'an inner cylindrical portion 24 and an outer conical part 25. A bolt 26 is extended 'throu h holes of both bosses 19 and. 23 andelect rough the-aperture-of the box ribl'l, the shank and 24;,I' provide the holt at one end with a head 28, and adjacent tov the side ofsuch head the bolt. is equip ed with a conical portion 29 shaped to cbn orm t0 and adapted tofit 'in the conical part of the aperture through the boss 23; Such 'conieal section oflthe bolt, as .will. be readily appreciated,

- holds the reduced shank 'o f-thc bolt out of contact with the walls oftlie holes24 and- 27.- The opposite end of such bolt is threads ed as at 30 and has screwed thereon a nut 31.

having aconical or externally-tapered .po 'rtion 32 ada fed to fit in and engage thev flare ing Wall 0 the aperture'f2l, the other face of such'nut havinga tapered cavity 33 for the! reception an spit look nut 35. 1 a

To those skilled in thisa t it will be parent that when the bolt has been 'putfliu place and the nuts" have been screwed up" 'ilzligiht, theconical parts 2'9 and 32 act-to o screw-threadedlportion of the bolt so that itd the bolt centrally with relation'tothe holes 20 2'and'27 and wholly out'ofcontact withtheir wa s. The split nut by lengagement with the inner comc'alfsurface oi theinut 31 is crampedor squeezed on to the 'efiecti'vely "operates" as a locking-nut, preventing back n np of the'nut 31, i It should" be noted also t at there is no-tendency for this bolttobecome loose-due tojvibrationon slight movement between separate castings,.

I for the reason that its two ends. are-effectroved evice' is p he rib 1'7 of thegour nal-box rismaintained contact with thab'olt 26 ively held in place by parts of the single iconnections, that they have no wear, upon them; and that their two'ends'are secured tothe'same integral casting, the boltsflnot joining together two separate independent side-frame casting.

.The. c eration =of, i PPH Q and. Flbstiamlally as follow atall times out '0 so that whatever movement may take place in the journal-boxcauses. nowearing what ever on the retaining bolt. The,pr.esence of. this bolt through theribfl'? not -inte1--' fere inQan-y way'fwith the slight rochin' of item the ijjournal-box sineefas wil 7 clear parts 20, 24 and accommodation of the ta ered or conical extension 34 of theouter wearingon. thejour an examination. of Fi 3,- the bolt isarranged concentric :to t e curved surface of the'rib 17 In. case the truck becomes upset this emergency bolt' becomes active to hold the j ournal-boxes, axles and wheels in assembled relation with respect to the truck, that is, these .boltsprevent the separation of the truck frame proper from its journal-boxes, axles and wheels. j I

' It is very im ortantthat a retaining des vice like the be t 26 shall be-efi'ectively held in place and shall be so maintained in position that it will'notbecome loose or work out .of place "even though-subjected to excessive vibration. The use of the split locking-nut prevents backing awayo'r loosening of'the nut 31, butv if for. anyreason such latter nut shouldturn slightly such backing'away movement of the nut would have but very "slight loosening influence on the bolt 26, ow1ng to the tapered connection of such bolt with the side-frame cavity.

Inthose forms and-Styles ofcartrucks i-n j which. the journal-boxes f are integral with the 'side-franies,- damage or injury to one only .of the pair of journaleboxes requires, the discarding of the entire side-frame, and

in such trucks-in orderto take out the wheels I andlaxles it is neoessary'to cut'the rivets got "all transverse bars icormectin together theftwo' 'si ile-tr'ames or. itnone 0 such bars are riveted to the sideiraines a necessarily weakconstruction follows. In the present ,formn-of truckthe twoside-frames can be oonnectedtogether'by any suitable nuinber of bars directly riveted'there'to, and. no outting,"o f such rivets is necessaryfor required when it desired to change the wheels, nor is'rit necessary to taketheltru'ck apart to roll out-thewheels and axles, as'is true-inlthe' above-mentioned style of truck even when 'the-siderframesare not fixedly connected together,-;b ecause owing to thehiact that the ournal-boxes are" integraljwith' the ,side I frames the latter-must be separated sufli- 'cient l .to free the ends'of the journals be-' fore t e wheels can be rolled out.
