MAX IVOLFF, OF CHICAGO, ILLINOIS.
RoLLER-BEARlNe.
SPECIFICATION formingpart of Letters Patent No. 551,940, dated December 24, 1895.
Application filed October 18, 1895. Serial No. 566,162. (No model.)
To @ZZ whom t may concern.'
Be it known that I, MAX WOLFF, a citizen of the United States,residing at Chicago,in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Antifriction Roller Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to a novel construction in an antifriction-roller bearing, the object being to provide a device of this character of simple and durable construction and efficient operation.
My invention consists in the features of construction and combinations of parts hereinafter fully described and claimed.
In the accompanying drawings, illustrating my invention, Figure 1 is a side elevation of the truck of a car provided with roller-bearings constructed in accordance with my invention. Fig. 2 is a sectional view taken on the line 2 2 of Fig 1 and showing the journal-box, roller-bearing, axle and wheel in detail. Fig. 3 is a sectional view taken on the line 3 3 ofFig. 2. Figs. 4, 5, 6 and 7 are detail views 'in elevation of parts composing the roller-bearing. Fig. Sis an end elevation of one of the rollers.
Referring now to said drawings, A indicates the truck of a car provided with journal-boxes B and wheels C mounted on axles D, the ends 1 of which enter said journal-boxes B. Surrounding the ends 1 of said axles D and f1tting within said j ournal-boxcs B are antifriction-roller bearings 2. The said roller-bearings 2 consist of two plates 3 and 4, between which rollers 5, 6, 7, 8, 9 and 10 are revolubly mounted on pins 11 and studs 12, as hereinafter described. The said plate 2 is preferably provided on its inner face with three pins 11 and three studs 12 arranged alternately and equidistant from each other. The said plate 3, pins 11 and studs 12 are preferably made of malleable iron, and in the ends of said peripheral portion of less width than the di' ameter of said rollers 5, 6, 7, S, 9 and 10. Said pins 11, studs 12 and bosses 14 have their centers situated equidistant from the centers of said plates and midway between the circumference and cut-away portion thereof, and are tapered at their outer ends. Said rollers 5, 6, 7, 8, 9 and 10 are hollow and their ends rounded oif, so as to leave no sharp corners, which have the effect of cutting into the material with which they come in contact. Said pins 11 and bosses 14 enter said rollers 5, 7 and 9, while said studs 12 enter said rollers 6, 8 and 10, thus comprising what may be termed the shafts of said rollers. After said rollers have been placed in their relative positions between said plates 3 and 4, the ends of said wrought-iron rivet-pins 13 are flattened out, thus riveting said plates 3 and 4 permanently in their relative positions. Said rollers are also preferably made of malleable iron, as I find that the wear on this material is less than on wrought-iron, thus extending the life of said antifriction-roller bearing. It will also be seen from the above that the wear on said pins and studs will be very slight, and by their tapered forms will take up wear to a large extent. Said antifriction-roller bearing is held in place in said j ournal-box B by means of an interiorly-projecting annular flange 16 on the outer end of said journal-box B and overlapping the outer edge of said plate 3, and by the wheel C which is fast on said axle D.
An antifriction-roller bearing constructed in accordance with my invention is cheap and durable, besides being very efficient in operation. As will be obvious, said roller-bearing will require little or no oil, which makes it valuable for use in hot places-such as kilns, &c., in which cars loaded with the material to be dried are used.
I claim as my invention- 1. An anti-friction roller bearingcomprising a plate 3 having'pins 11 mounted thereon IOO and provided at their other ends with rivet pins 13, studs 12 on the said plate between said pins 11, a plate 4 having` openings 15 to receive said rivet pins 13, studs l2 on said plate 4 of saine size and location as said studs 0n said plate 3, and rollers mounted on said pins and on said studs, substantiallyas described.
2. An anti-friction roller bearing comprising two plates 3 and 4, said plate 3 having tapered pins provided with rivet pins at their other ends, and said plate 4 having openings 15 to receive said rivet pins 13 and bosses 14 surrounding` said openings 15 and adapted to `receive the ends of said pins 11, and rollers
