"Letters Patent No. 112,513, dated March?, 1871.
" `IMPRoyEMENf-r|N DEVICES FoRcooLiNe JOURNALS oF RAiLwAv CARS.
'i The Schedule referred to in these'Letters Patent and making part offthe -same.
To allwhoin 'itmay concern: l d i :Be .it known that I, HENRY G, THoMPsoN, of Milford, inthe countylol' New Havenand State of Y Oon- "neoticnn-'hare -invented an Improvementin Uooling i the Journals 'ofi Railroad-Gar Axles;` and `the follow-` ing Ais declared to be a correct descriptionol thev saine.
Elorts' have heretofore been made to prevent the `accumulation of "lfrictional heat in railroad-car`axles by meansof acurfrent of air circulating througliithe hollow axle, `an 'opening being provided at 'theou'ter'end,
audthere being lateral discharge-openings `in the axle l In axles that `are-thus litted'the oil that is employed fof :lilbricating is liable "to be'splashed into the hfollow lalxle, or else work into the-same by`capillary attrac' `tion,anld the dust in the current of air, adhering to the' oily surface, `formsaycoating that intervenes between thelmetal and the 'current o'fair to prevent lleatibeing conveyed away by the air, and the opening'becomes`1no1'e or less iilled with the accumulation `llnake use. of` a tube. within the hollowaxle, said tubeheing,perforated near the outer end, and the in- `ner end connecting with alateral opening through the 'a'xl'e ;f and a second opening is provided through the axle, communicating with the spaoearound this tube,
'i so `that a circulationof'aii `can'be maintained through the hollow journal without any opening from the journal into the oil-box, therebyellectually excluding any i oil or grease from the hollow journal` `In the drawing-7- l my improvement; ,i `Figure 2is an end view oi' said axle; and
Figure is a partial' longitudinal of an' axle, illus- 'Altrating my improvement in a modi'ed form.
`The axle wis oi any usual character, with ajournal,
l b, either inside orQnt-sidejof' the'wheel. I have shown axles that areadapted tothe reception `of wheels inside of. the journals. 1 f
,j'lheajxle is made hollow by a h ole, c,bored or formed inthe center lof the same, and within this is a thin `Figure lis partial section of a car-axle lmade with 4sheet-metal tube, d, the sectional area of which is about half the sectional area of the hole o.
As a convenientvmeans of holding this tubedin place it is shown as attached at the'outer eudeto the cap e, vthat `is secured iirmly to the end of the journal by screws, andtheiuner end .of this tube d enters' a reduced portion at the end ofv the hole c and there connects with the lateral opening h; j
rlhe lateral opening i communicates with the'hole c, and the tube d isperforated'or formed with slits or holes neartheouter end7 so that a current of' air will circulate through the axle and journal, passing along `in the hole c and-,returning through the tube el tothe opening h, or the reverse, and there is nothing of oil' or grease that can get into the air-tubes hence `the air will circulate freely and there will not be any, deposit of dust to obstruct the air in keeping the journal cool. p
u The lateral openingsh'iare to be provided with lany suitable appendages to aid the operation -to be performed; they may be covered with hoods l l, with a wire-gauze over their mouths, as seen in figs. l and 2,
so that one hood will act as an injector and the other as an exhaust, and these operations will be transposed when the direction ol' revolution of the axle is reversed. Iu iig. 3, I have shown a screen, m, on the lateral opening i, and a t'ube, n, upon the opening it, so that the centrifugal action will produce a circulation out of j the tube n and drapr the air through the tube m, hole t', and tube d, to keep the journal cool, as aforesaid.
A .long,narrow division-plate, fitting the hole c and extending from its inner end toinear the cap e, mayv take the place of the tube d, the air circulatingI along on one 'side of such division and returning ou the other. l
l lclaim as my invention- The tube d or division in the hollow journal or axle, combined with the lateral openings h t', to effect 4aciroulaton of atmospheric air through the hollow jour- `nal to convey. away frictional heat, subst-antiallycas setlforth.
Signed by me this 20th day of "December, 1870. Witnesses: HENRY G. THOMPSON.
