JOURNAL-BEARING.
SPECIFICATION forming part of Letters Patent No. 413,081, dated October 15, 1889.
Application filed January 22, 1889. Serial No. 297,196. (No model.)
To ail whom-it nwy concern:
Be it known that I, JOSEPH T. MURRAY, a citizen of the United States, residing at New ark, in the county of Essex. and State of New Jersey, have invented certain new and useful" Improvements in JournalBearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.
This invention relates to journal-bearings, and has for its object to provide for the perfect distribution of the lubricating material upon the entire wearing-surface with but little waste or use of the lubricant.
This invention therefore consists in the provision of a journal-bearing with grooves and pockets so arranged that the lubricant can be applied either in a solid or semisolid ora liq uid condition, and in either Way it will be thoroughly applied with butlittle, if any,waste to the entire bearingsurface of the journal.
My invention further consists in the provision of a journal-bearing having a series of grooves so arranged that the heating and cutting of the journal and bearing will be reduced to a minimum, if not entirely avoided.
My invention still further consists in the provision of a journal-bearing having certain peculiar and novel features, which will be more fully described hereinafter, and specifically pointed out in the claims.
Referring to theaccompanying drawings, Figure l is a longitudinalsectional view of a journal-bearing of myimproved form Fig. 2, a transverse sectional view of the same; Fig. 3, a longitudinal sectional view of a modification of the same. Fig. 4 is a transverse sectional, and Fig. 5 a perspective, view of the hearin A represents the body of the journal-bearing having a number of ridges or projections a a, which, as shown in the drawings, are sawtooth shaped, so as to form a series of wedgeshaped pieces Z) I), having their sides converging at one end and diverging at the other end, the larger end of one piece being adjacent to the smaller end of the next piece. These ridges or projections a a; form between their outer edges a series of similarlyshaped depressions or continuous grooves, (designated 0 c.) In the center of each of the wedge-shaped pieces I) b are formed triangular pockets d d. It will be noted that the raised portion consists of a series of saw-tooth lines which run at an angle with the line of motion of the shaft, and that as the shaft is rotated a portion of its surface will bear upon one or theother of these lines at all times, but that the bearing will not be in a line with the motion of the shaft. The grooves and pockets in which the lubricant is stored overlap each other in such a manner that it is impossible to rotate the journal without its entire surface coming into contact with the lubricant during a single rotation. The walls of the grooves or channels are made to converge in the direction of rotation of the shaft, and hence there is no tendency of the lubricant to be forced out of its seat, but, on the con trary, it will be forced by the pressure and im pact of the shaft more firmly into place, thus preventing waste and keeping the shaft constantly and permanently lubricated. The grooves c c are filled with a solid or semi-solid lubricant, and the pockets d (Z are either filled .in the same way or with a liquid lubricant,
or else allowed to become filled withthelubricant drawn from the grooves during the rotation of the journal. here the grooves are filled with a solid lubricant the same may be forced therein under pressure, so as to form a practically solid lubricating bearing for the shaft.
In the modification shown in Fi 3 of the drawings the raised lines (designated 6 e) are of the general sawshaped form. as that shown in Fig. 1; but instead of having angular pockets in each of the wedge-shaped pieces the lines form continuous grooves f f between them. This form of bearing I prefer where it is to be applied to a reciprocating sh.aft-- as, for instance, to pistonrods-although either of the forms may be used on reciprocating or rotary shafts.
I am aware that it is not new to provide a journal-bearing with depressions for the reception of a lubricating material, and I do not broadly claim the same.
hat I claim as new, and desire to secure by Letters Patent, is-
, 1. A journal-bearing provided withaseries of grooves or depressions Whose outer edges diverge and converge throughout their entire length, and form eontinous circumferential channels consisting of a series of Wedge-shaped communicating chambers adapted to hold a solid or semi -solid lubricant, the sides or Walls of said chambers converging in the direction of rotation of the shaft, substantially as described.
2. A journal-bearing provided with aseries of Wedge-shaped grooves and a series of angular pockets, said grooves and pockets overlapping each other at their ends, the grooves forming continuous circumferential channels consisting of a series of Wedge-shaped communicating chambers adapted -to hold solid or semi-solid lubricant, the sides or Walls of the chambers converging in the direction of rotation of the shaft, substantially as described.
In testimony that I claim the foregoing I have hereunto set my hand this 8th day of January, 1889.
JOSEPH T. MURRAY.
