SPECIFICATION forming part of Letters Patent No. 581,378, dated April 27, 1897.

Application filed December 26, 1896- Serial No. 617,016. (No model.)

To aZZ whom it may concern.-

Be it known that 1, WILLIAM 1V. \VAIN- WRIGHT, of Oonnersville, Fayette county, Indiana, have invented certain new and useful Improvements in Journal-Boxes, (Case 0,) of which the following is a specification.

Attention is called to P. H. & F. M. Roots Oompanys patent No. 525,775, dated September 11, 1894, for improvements in journalboxes, granted on my application. The present invention pertains to journal-boxes of the type set forth in that patent, and the present improvements relate to features of construction designed to enhance the facility with which the box may be adjusted and to provide for its lubrication.

The present improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a side elevation of theimproved journal-box; Fig. 2, a vertical longitudinal section thereof; Fig. 3, an end view thereof; Fig. 4, a vertical transverse section thereof, and Fig. 5 an enlarged duplication of a portion of Fig. 2.

In the drawings, 1 indicates the fixed support for the journal box, be it housing, hanger, pedestal, or what not, this support having a cylindrical bore; 2, the cylindrical bore in question, this bore in the exemplification not extending entirely through the support, but, on the contrary, having at one end a reduced portion approximately the size of the shaft; 3, an adjusting-sleeve having a cylindrical exterior fitting the bore of the support, the sleeve being seated in the inner end of the bore of the support and longitudinally cut into a number of segmental sections-three in the examplethe inner bore of the sleeve being tapering, with its larger end toward the center of length of the journal; 4, a similar ad j Listing-sleeve in the outer end of the bore of the support, the inner ends of the two sleeves being separated some distance; 5, the bearing-sleeve, bored to fit the journal, and tapered exteriorly at each end to fit the adj Listing-sleeves, and longitudinally cut, so as to be capable of contraction of diameter; 6, studs with their inner ends engaging the sections forming adjustingsleeve 3, their outer ends passing through the sections forming the adjusting-sleeve 4t and being provided at the outer end of sleeve 4 with adjusting-nuts, by means of which the sections forming the adjusting-sleeves may be drawn toward each other longitudinally, the studs 6 being disposed at such radial distance from the center of the bearing as to pass through longitudinal grooves in the crown of bearing-sleeve 5, whereby the studs prevent the rotation of the bearing-sleeve with reference to the adjusting-sleeves; 7, the shaft; 8, an oil-chamber formed below the support 1 and extending substantially the length of the bearing; 9, a circumferential groove disposed at about the center of length of the bore of bearing-sleeve 5; 10, ports leading tangentially downward from groove 9 at each side of the bearing, these ports leading to the space between the inner ends of the adj Listing-sleeves; 11, a port through the floor of support 1, below ports 10, and forming an opening through the roof of oil-chamber 8 12, an endless chain hanging on the shaft within groove 9 and passing down through ports 10 and 11 into and near the floor of the oil-chamber; 13, stop-lugs projecting inwardly from the ends of the lower sections of the adjusting-sleeves in position to pass between the two leaves of the chain and abut against each other and limit the approach of the adjustingsleeves, so that the adj Listing-sleeves cannot clamp upon the chain; 14, an end cover for the outer end of the oil-chamber; 15, a collar of angle cross-section fitting upon the shaft at the inner end of bore 2; 16, afelt ring engaging the angle of this collar and a counterbore formed in the end wall of bore 2 around the shaft; 17, an angle-collar on the shaft at the outer end of bearing-sleeve 5; 18, a felt ring carried by this collar and presenting its inner surface against the end of the bearing-sleeve; 19, an inwardly open hollow collar surrounding collar 17 and its felt ring, but supported free from contact therewith; 20, a bracket secured to lid 14 and collar 19 and serving to support the latter, this bracket having an oil-channel leading from the interior of collar 19 through lid 14 into the oil-chamber; 21, a port leading from the inner end of bore 2 into the oilchamber, and 22 a removable plug in the wall of the oil-chamber, typifying means for permitting the filling of the oil-chamber.

The movements of the sections of the adjusting-sleeves to effect compensation for the wear of the journal and hearing are as in the earlier patent before referred to. In the present case the adjustment is efiectedby turncases-as, for instance, in rotary blowers,

where the box projects from the outer surface of the head-plate of the blower-where only the outer end of the box is accessible. In the present case the bore of the support has an annular wall at its inner end, and felt 16 serves to prevent the passage of lubricant beyond this wall from the bearing. Gollar-15 is merely a snug [it upon the shaft,so that it can be readily removed, as is alsothe case with collar 17.

The turning of the shaft gives travel to the chain which carries up the lubricant, which tends to distribute itself over the entire length of the journal. Surplus lubricant reaching the inner end of the journal is intercepted at collar 15 and is returned through port 21 to the oil-chamber. Surplus lubricant reaching the outer end of the journal is intercepted at collar 17 which by centrifugal force throws it into collar 19, from which it flows back to the oil-chamber.

In the ordinary use of lubricating-chains thebearing is split or capped and no difliculty is presented in assembling the parts, it being practicable to remove the bearingcap and disconnect the chain, uncoupling it if necessary; but in a hearing which is not capped and where all manipulations must-be made from one end of the bearing the case is different and the chain introduces serious difliculties. In my construction, however, it is to be observed that the lower one of segments 4 may be removed endwise from the cylin-. drical support 1, thus permitting access by danger of pinching the chain in adjusting the bearing is guarded against by the lugs 13.

from said journal within said groove and passing through said ports into said oil-chamber, and accessible from the end of said support below said bearing-sleeve, a pair of adj ustingsleeves bored to fitsaid tapers on the bearing-sleeve and having their exteriors fitting the bore in said support and formed in segmental sections, the segments of one of said adjusting-sleeves beingcremovable endwise from said support and bearingsleeve, and screws for moving the segmental sections of the adj IlSlJiHg-SIOGVGS endwise independently.

2. Ina journal-box, theoombination, substantially as set forth, of a support having a cylindrical bore, alongitudinally-cutbearingsleeve disposed therein and having an exterior taper at each end, a pair of segmental adj ustin g-sleeves bored to fit said tapers and having their exteriors fitting the bore in said support, means for moving said adjustingsleeves endwise, an oil-chamber formed below said support, a journal engaging said bearing sleeve, an endless it chain engaging said journal and extending downwardly between the contiguous ends of the lower segments of said adj Listing-sleeves and into said oil-chamber, and lugs projecting from the inner endsof saidlower segments of the adjusting-sleeves and adapted to make contact with each other before the inner ends of said segments reach the chain.

. 3. In a journal-box, the combination, substantially as set forth, of a support, a bearin g therein, a shaft engaging said bearing, an

ICC

oil-chamber disposed below said support, an

endless chain engaging said shaft and dipping into said oil-chamber, a removable collar on said shaft at one end of the bearing, a soft ring, as of felt, carried by said removable collar and engaging one end of the bearing, a hollow collar encircling said removable collar and soft ring and supported free thereof, and a bracket supporting said hollow collar and having a channel leading therefrom to said oil-chamber.
