MASSACHUSETTS, ASSIGNOR TO DAVIS &

TION OF MASSACHUSETTS JOURNAL-BEARING CONSTRUCTION Application filed September 13, 1926. Serial No. 135,067.

This invention relates to a ournal bearing construction wherein a journal bearing sleeve having a lubricant-holding recess communicating with the bearing surface is employed, and the object of the invention is to provide means for positioning the bearing sleeve with the lubricant-holding recess at the top independently of the angular position of the hearing block in which the sleeve is mounted.

The invention is particularly designed for use in a carding machine in connection with the bearings for the worker and stripper rolls, the bearing blocks for which are necessarily mounted in various angular positions around the arch of the frame.

The objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

While the invention is applicable to various bearing constructions in various machines, it is particularly useful in connection with a carding machine and a simple and preferred form of construction embodying the invention is here illustrated in connection with such a machine.

In the drawings:

Fig. 1 is a side elevation of a portion of the arch of the frame of a carding machine with one unit of a worker and stripper roll in one angular position thereon.

Fig. 2 is a detail partially in end elevation and partially in section of a portion of the bearing for the stripper roll shown in Fig. 1.

Fig. 3 is a view partially in transverse section on the line 33 of Fig. 2.

In the particular construe-ton illustrated, a portion of the arch 1 of the frame of a carding machine is shown. Such an arch is usually formed on a circular arc and a plurality of units, each comprising a worker roll and a stripper roll, which are located in clifferent angular positions, that is, on different radii of the arch, usually throughout substantially 180.

In the construction illustrated, a single unit is shown in one angular position. This unit comprises a base plate 2 secured at the required angular position to the arch and on this base plate is adjustably mounted a bearing block 3 for the worker roll 4 and a bearing block 5 for the stripper roll 6. It will thus be seen that these bearing blocks may occupy any angular position, or any position radially of the arch, from the vertical to substantially the horizontal and in the illustrated position are shown between these two extreme positions.

The bearing construction in the case of both worker roll and the stripper roll is the same sothat it is only necessary to illustrate and describe in detail but one, and for that purpose the bearing construction of the stripper roll is taken.

It will be understood, of course, that the construction may be and is preferably the saplie at each end of the worker and stripper ro s.

The stripper roll 6 is provided at each end with a journal 7 On this journal is mounted a journal bearing sleeve 8. This sleeve is provided on the top or upper side with a lubricant holding recess 9, herein shown as a shallow cup formed in the metal of the sleeve and adapted to receive a supply of oil, grease or other lubricant. This recess, by means of suitable apertures 10 extending from its bottom through the sleeve, communicates with the bearing surface and serves to lubricate the journal 7.

It will be seen, therefore, that it'is necessary that this lubricant-holding recess 9 shall always be located at the topquite independently of the angular position of the bearing block on the frame of the machine and it is the principal object of the invention to secure this result.

The bearing block 5 is provided at its upper end with a curved seat, preferably semi-circular, and preferably presenting an open mouth. In the particular construction illustrated, this seat presents the opposed frustoconical surfaces 11 and the intermediate surface 12.

The sleeve is preferably formed with an annular flange presenting opposed frusto-conical surfaces 13 cooperating with the surfaces 11 and with an intermediate flat surface 14; between.

A plurality of circumferent-ially spaced recesses and a cooperating projection are located, the one at the exterior surface of the sleeve and the other at the surface of the bearbearing sleeve as illustrated.

It will. thus be seen that'when the bearing sleeve is inserted in the bearing seat, preferably by being inserted transversely through the open mouth of the bearing seat in the construction illustrated, that one or the other of the recesses 16 may be brought into cooperation With the projection 15 so as position the lubricant-holding recess 9 at the top, no matter what may be the angular position of the bearing block itself. WVhen the journal bearing sleeve has thus been placed in position, it is thus held, usually by gravity, in its adjusted position with the lubricant-holding recess'at the top, and thus there is no danger of the lubricant spilling or working out from the recess whatever may be the angular position of the bearing block.

Having thus described the invention, whatis claimed as new, and desired to be secured by Letters Patent, is:

1. A journal bearing construction comprising a journal bearing sleeve having a lubricant holding recess communicating with the bearing surface, a bearing block having a curved seat cooperating with'the exterior surface of the sleeve and supporting the sleeve, and a plurality of circumferentially spaced recesses and a cooperating projection located the one at the exterior surface of the sleeve and the other at the surface of the bearing seat whereby the sleeve may be positioned and held in the seat with the lubricant recess at the top independently of theangular position of the bearing block.

2. A journal bearing construction comprising a journal bearing sleeve having a lubricant holding recess communicating with the cant holding recess communicating With the bearing surface, a bearing block having a semi-circular open mouth seat into whichthe sleeve is inserted through the mouth and cooperating positioning means on the sleeve and bearing block acting to hold the sleeve, when seated, with the lubricant recess at the top independently of the angular position of the IRVING C.
