JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 617,550, dated January 10, 1899.

I Application filed September 8,1898. Serial No. 690,454. (No model.)

To all whom it may concern.-

Be it known that I, J OHANNES APPEL, a citizen of Germany, residing in the city of New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Journal- Bearings, of which the following is a specification.

This invention relates to certain improvements in the journal-bearings for which Letters Patent of the United States were granted to me, No. 453,826, dated June 9, 1891, said improvements being designed with a View of reducing the friction between the journal of the shaft and the bearing of the pillow-block, in which the shaft is supported.

The invention consists of a journal-bearing which comprises a pillow block and cap, bearing-rings located in the same, a supportingring guided by said bearing-rings and provided with transverse openings, and antifriction-rollers extending through said openings, said antifriction-rollers rolling progressively on and between the journal of the shaft and said bearing=ringsg and the invention consists, further, in means for the lubrication of each roller in said pillow-block and cap, as will be more fully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a sideelevation of a pillow-block provided with my improved journal-bearing. Fig. 2 is avertical longitudinal section through the pillow-block and bearing. Fig. 3 is a vertical transverse section on line 3 3, Fig. 2; and Fig. 4 is a vertical longitudinal section, as in Fig. 2, but showing the ring of the shaft in section.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a pillow-block which is supported in any suitable manner. a

B is a cap which is screwed by means of the screws 0 to the pillow-block A.

At the interior of the pillow-block are ar ranged two bearing-rings D D, upon which bear a nu mber of antifriction-rollers G, which are supported in transverse openings of a supporting-ring F, that extends around the journal E of the shaft said ring being located between and guided by the bearing-rings D D.

My improved journal-bearing is lubricated from an oil-cup B, arranged at the top of the pillow-cap B, said oil-cup communicating with the interior of the pillow-block by an aperture 6. The openings in the ring F for the antifriction-rollers G are so arranged that the antifriction-rollers project somewhat beyond the inside of the supporting-ring F, soas to form contact with and roll progress ively on and between the journal E of the shaft, as shown in Fig. 3, and the bearingrings D D. The antifriction-rollers are retained in position in the supporting-ring F by the side walls of the'pillow-block and cap. The supporting-ring F for the antifriction-rollers Gis further provided with a central grooveg in its outer circumference, which groove communicates by radial openings 0 with the transverse openings for each of the antifriction-rollers, so that the-lubricating material supplied from the oil-cup B can pass through the opening 6 into the groove g and through the openings 0 to the circumference of each of the antifriction-rollers and from the same to the journal and the interior surface of the bearing-rings, whereby a uniform lubrication of the rotating parts is kept up. During the rotation of the journal E of the shaft the supportin g-ring F is carried along asthe anti-friction-rollers rotate in contact with the journal and the bearing-rings.

The advantages of my improved journalbearing as compared to the journal-bearing heretofore patented by me are that in my present construction one set of antifrictionrollers only at each end of the shaft is required, and they are supported in place by the central supporting-ring, so that the parts of the journal-bearing can be assembled with great facility and access be had readily at any time to any of the parts.

Second. The uniform distribution of the lubricating material takes place through all the bearing-surfaces from the center of the pillow-block.

Third. By reason of its simple and strong construction my improved journal-bearing is adapted for all kinds of shafts, and espe-- rangement of antifriction-rollers and by the efiective lubrication of the same.

cap, bearing-rings located in the same, a sup-i porting-ring located between said bearingrings and provided with transverse openings, and antifriction-rollers extending through said openings, said antifrictiolrrollers rolling progressively on and between said bearing-rings and the journal of the shaft, and said supporting-ring being provided with an exterior groove and radial openings in said ring opening into the groove opposite each roller, so as to distribute the lubricating material to the antifriction-rollers and journal, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
