SPECIIPICATION forming part of Letters Patent No. 286,5'65, dated October 9, 1883.
K Application iled July 527, 1883. (No model.)
To dit whom t may concern.- Be it known that I, S. STUART WILLmMson, a citizen .of the United States, residing at A Bridgeport, in 'the county of Fairfield and v State ot' Connecticut, have invented certain new and useful Improvements in Car-Journals; and I do hereby declare the following to bea full, clear, and exact description of thevinvention, such as will enable others skilled in the art to which it appertains to make and use the same. t j
My invention relates to certain new and useful improvements in car-journals, and has for its object to provide an anti-friction journal 5 and bearing which shall be simple and durable; and with these ends in vienT my invention consists in the details of construction and combination of elements hereinafter fully and in detail explained, and then 'specifically desig- :ao nated by the claims.
In order that those skilled in the art to which my invention appertains may more fully understand its construction and operation, I uil proceed to describe the same in detail, re-
ferring by letter to the accompanying drawings forming a part of this specification, in Which- Fig. l is a side elevation of a truck with my improvement attachedgFig. 2, a plan view. of one journal, the truck-frame being removed to 3o show' more clearly the relative position ofthe anti-friction wheels; Fig. 3, a front vieWjofv the same, the side bar and boxing being in ,sect-ion, also a-portiou of the periphery of the wheel beingbroken away; and Fig. 4 is avieW 3 5 of a pair of the anti-friction Wheels.
Similar letters oi're ference indicatelike parts throughout the several views of the drawings. A is the track-frame, of ordinary construe tion, and B are the truck-Wheels. Side bars, 4o C, (but one of which is shown in the drawingsg) may be oi' any convenient shape, having down- Wardly-projecting housings D. Also in said sid bars are formed journal-boxes c, in which t axles c otheantifriction Wheels E lit and rotate. These Wheels are made in pairs, as
4.. Z//shvn in Figql, so that there will be no unequal strain on them or their bearings. Said Wheels E, Whenjournaled in side bars, C, form Vshaped bearings for the journals F of the truck-wheels B, the said journals F being re- 5o tained in close contact With Wheels E by means of boxiugs G, adapted to t between housings d), and' held in place by caps I and adjustingscrews K, or in any suitable manner.
By allowing the journals of Wheels E no play 5 5 in the side bars, and keeping the boXings in close contact with the journals F, I prevent the hammering out of said Wheels E, which has heretofore been the difficulty with devices for this purpose. Also, by having the Wheels E in pairs and journaling them in the center, I economize space, and gain strength and durability.
' The side bars, C, are preferably bent or otherwise formed with downwardly-projecting curvatures, so that the spring-seats or the points L on which the lower ends of the carsprings rest shall be slightly lower than the horizontal center of the axle-journal, whereby a" hanging bearing 7 is provided, and agreater 7o self equalizing, balancing, or self-adjustment is secured between the anti-friction wheels and the axle-journal.
By providing beveled flanges M and O on the axle-journal, and loosely iittingl the beveled boxings G between said ilanges, the end thrust of the axleis sustained bythe boxing Without injury or strain to the anti-friction Wheels. This construction obviates the objection heretoforev existing against anti-friction Wheels, l8o` Where, to the Weight of the car, was added the end thrust and longitudinal pressure of the axles against the anti -i'riction Wheels, causing their gripping upon their bearings, and, heretoi'ore, greatly reducing the anti-friction quale 85 ity of said Wheels.
It is obvious that the side bars may be made of any suitable perpendicular Width to secure the requisite strength, and that cross-bars, &c.
may be secured thereto to form suitable con- 9o l i nection With the truck. I leave this part to the mechanical ingenuity of the car-builder, asin my device itis aimed to simply provide a practical anti-friction journal in which former difculties in the use of anti-friction Wheels shall be overcome, and in which a practical combination and arrangement of essential parts shall be secured.
lHaving thus fully described my invention, what I claim as new and useful is- Y l. In journals for cars, thetwo pairs of anti-friction wheels E, each having` single axial bearings between the wheels thereof, and in a bar connecting1 the pairs, in combination with housings D and boxing G, said boxing` receiving the end thrust of the car-axlethrough shoulder O, substantially as and for the purpose set forth.
2. In journals for ears, the axle F, having4 shoulders O and M, in combination with boxing G, fitting loosely between said shoulders, andthe two pairs of anti-friction wheels E, eaoh pair having a single axial bearing or journal in bar C, said bar passing` between'the wheels of each pair, respectively, substantially as and for the purpose set forth. Y
formed so as to provide spring-seats L on a line below that of the horizontal center of the 25 car-axle, whereby lan equalizing hanging of the bearings is secured, substantially as and for the purpose set forth.
' In testimony whereof I affix my signature in presence of two witnesses.
