GAR-AXLE.

To. all whom it may concern :1 i

Be it knownthat I; WELLINGTON RANDALL,

a citizen of "the United States; residing at 'Marysville, in the county of Snohomish and State of Washington, have inventedcertain new and useful Improvements in Car-Axles, of which the following is a specification: My invention relates to improvements in car axles of the divided type andresides in the provision'of an inexpensive and durable car axle that will enable independent turning of thewheels so as to eliminate wear on the wheels and strain on the axle in rounding acurveg I a a An object of importance is to provide novel means for .securely holding the divided axle in assembled position in such a way'that thewheels are permitted'to turn relativetoieach other and the axle will rotate freely. r L Anotherobjectofimportance is to provide lubricating means arranged in a novel manner so that the axle is lubricated in 'a most reliable manner thus eliminating unnecessary wear on the bearings. 7

Another object of importance is to provide anaxle of the character describedthat is simple a as to construction, reliable and eflicient in operationandinexpensive to manufacture. A

The above andadditional objects are accomplished; by such means as are illustrated.

in the accompanying drawings described in the following specification and then more particularly. pointed out as claimed.

, VVith'reference tosthe drawings,wherein I have illustrated the referred embodiment of my invention asit is reduced to practice, and throughout the several views of which similar reference-numerals designate corresponding parts, Figure v1 is a longitw dinal sectional view taken through my improved divided axle showing the same asit would appear when in assembled i position, Fig. 2 is a transverse sectional view taken on theplane of line of Fig."1,"Fig. 3' is a transverse sectional view taken on the plane of line 33 of/Fimlyand Figs is a fragmentary detail perspective view'of one of the parts of the divided axle andbearing members thereon.

Specification of Letters Patent.

. longitudinally Referring to the drawings by: ch'arac I v y Patented Sept. 1, 1914-; Application fiIedMay 16, 1914. I Serial No. 839,033. a

ters of reference the numeral 1 designates as an entirety, a-divided a-Xleconsisting of two semi-cylindrical rods or ,axle portions 2 that are secured to each other to provide a cylindrical axle and have shrunk on their ends as at 13 the usual flanged railway wheelsaw r v As a means for securely holding theaxle portions2in assembled positionyl provide cooperating semi-cylindrical members 5 that are equal in length approximately to the dis-- tance between the inner faces of the-wheels, I d

are similar as to construction and provided upon their flat faces withgrooves extending to cooperate and receive the axle'l. i

To clamp the members 5I providebands or rings'6 atthe ends ofthe members 5 which surround said ends and arepreferably shrunk on. The members 5 are of larger diameter at the center than at the ends, being made tapering from the center to the ends 7 as shown in Fig. 1 in the drawings. :A'ring '7' of. larger diameter :than the ones 6 is mounted upon the central portionof each of the members 5 soas .to surround the same and is shrunk on in the same manneras are therings6.-:.

iThe'axle lcomprises four'axle portions 2, I

each being semi-cylindrical in :cross section. I

The axlel is divided at the center. Thus each of the axle members 2 is" equivalent to half the length. of the axle as a whole. On

eachrof the axle portions 2. is placed a semicylindrical bearing flange 8 that whenfitted to the flanges comprises a cylindrical'bean. I It willn'thus be seen thata ing portion. I bearing portion isprovided for each half of the aXleandsaid bearingportions are arranged to engageeach other at their inner faces as shown in Fig. 1 in the drawings.

The lower member. 5 is provided with 'a 'semi circula'r recess 9 centrallyfofits; ends and in its flatface, arrangedtransversely of the member and snugly receives the bearing portions comprising the members 8;".- .Mounted between the portions 8 is a circular Wear plate 9 that fits snugly within therecess-9 and prevents unnecessary wear on-the bearing portiOnsS. Formedin the opposing face oil? passages 13, that communicate, With the,

recess 10 on opposite sides of the bearing members 8. The outer face ofthe oil=cup 12 is disposed approximately flush with the outer; surface; of? the upper member 5. Semi-circular recesses 1e similar to; the one 10 are formed in, the opposed facesof the members 5, adjacent to theend's thereof and receive semi-cylindrical bearing portions 15 rigidly, connected with the axle members 2.- Theinner faces. of. the bearing portions 15 engage certain side faces of the recessesl l. The bearing. members15v are. similar to the ones-,8 and arearranged so that therecesses 10] provide oil; receiving: compartments; The bands or rings: Gare recessed on their outen and; upper; faces: as at 1,6 to receive oil cups. 1? that: have their outer faces flush with: the bands- 6.; and; inner ends communicating vvith the recesses lah, Arrangedxintermediate the end members 15 and central members 8'. are bearing members 18 similar to the ones-8andl5 andimounted recesses similar-totheones 9 and 10. A passage 19' isforrned on opposite sidesof theopposite sides:of the recess 10 and communicates at its-.endswith the recesses-for the members 18 'inthe upper-member 5.-andthe recess 10. This arrangement provideslfor the-lubrication of; the @members "18:.

Itewill bereadily-seen that I have pro: vided; novel; lubricating means for. my ime proved divided axle that will serve in an extremely effective manner to expeditiously lubricate. all of the bearing parts ,of; my. device: so as to prevent undue friction and Wear.- The rings 6' and 7 not only. serve to secure the parts 5 together butserve to hold oilrcups in such'a Waythat they donotinterfere. with the attaching of;the axle to rail- Way cars. 7

It Willebe readily. seen that With my im: proved device the Wheels e are .permittedto moverelative. to each otherandthus a great amount" of Wear is. eliminated in rounding curves and: under other conditions.

Inipractice, fhavefoundrthat the form ofrmy invention, illustrated in the drawings and referred to in the above description, .as

the'preferred embodiment, isthe most eiii? cientf and" practical yeti. realizing that the conditions concurrent with theadoption of device 'Will necessarily vary, I. desire to emphasize the fact; that: various minor changesv in details of! construction, proper:

tion and arrangement of parts may be resorted to, when, required, Without sacrificing any of the advantages of 'my invention, as setforth.
