JOURNAL-BEARING.
'SPECIFICATION forming part of Letters Patent Nb. 286,927, dated October 16, 1883.
` Application filed January 16, 1580.
To all whom it may concern.-
Be it known that I, DAVID A. HOPKINS, a citizen of the United States, residing at Park Ridge, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Journal-Bearings, of which the following is a full, clear, and exact specification.
My invention relates to an improvement in journal-bearings, its object being toso construct a journal-bearing as to cause the jourf nal side to become quickly self-tting to the journal when in use, and subjected to loadpressure, aided by the rotation of the journal, the same being effected by the yielding of the soft metal ormaterial presented on the journal side of the bearing, the pressure exerted on the bearing when in use, combined with the rotation of the journal, causing the soft metal superimposed or arranged on `and`secured to the unyielding portion of the bearing not only to yield and spread, but to automatically adjust itself and partake of the contour of the journal.
To this end my said invention consists in constructing a journal-bearing of two different metals, one of said metals being of a soft or yielding character and the other of a hard or unyielding nature, the one possessing the soft or yielding nature presenting ridges or spurs on the journal side of the bearing,`whicl1 receive the initial pressure of the journal, and by the rolling action or rotation of the same and the load-pressure upon the bearing become crushed down, spread, or displaced to the varying extent required at different points along its length, to shape the surface of the soft metal ridges as needed to insure their 'conformity with the contour of the journal, the result being that the surfaces of the soft-metal ridges in contact with the journal become automatically and quickly adjusted thereto by the yielding of said ridges rather than by their being worn to a fit. Between the ridges or spurs should be placed any suitable lubricant of a quality or character sufficiently stiff to retain itself in position between the ridges or spurs when in its normal condition, but which will be converted into a fluid when subjected to a moderate heat. I i
j ournal-bearing. Fig. 4 is a perspective view of the body or unyielding portion of a journalbearing detached from its iron casing.' Fig. 5 is a perspective view as an entirety of the ridges or spurs made of soft or yielding metal and detached from the hard body or unyielding portion of the journal-bearing.
In the drawings, A represents a j ournalL bearing of any suitable or desirable construe; tion, made of a metal or an alloy of metals possessing a hard or unyielding naturefsuch as brass-upon the journal` side of which is arranged or fixed a series of ridges or spurs, a a, ,composed of a soft or yielding metal-*such as Babbitt metal, or such'as is usually employed in lining journal-boXes-Y-for lessening friction' and reducing the cost of manufacture of the bearing complete. These ridges or spurs are shown as preferably formed by me with a backing, b, for connection by solder or otherwise witlrthe hard or unyielding metal portion of the j ournal-bearing, as shown in Figs. 3 and 5 of the drawings, which is a very convenient and practical mode of applying the invention. By so constructing the ridges or spurs and adapting the same to the journal side of the unyielding body or portion of the j ournal-bear ings, a series of spaces or grooves, @,will intervene between the ridges or spurs which form receptacles for a lubricant, a. The lubricant employed should be plastic, like tallow, when mixed with black-lead, or sufficiently stiff to retain itself in position when placed between the ridges or spurs when the journal-bearing is not in use. The soft-metal or yielding ridges or spurs receive the initial pressure of the journal when in use, and by the rolling action of the same and the load-pressure upon the bearing are caused to .yield and be crushed down and spread in conformity with the contour of the journal, so that the surface of soft IOO . nal-bearing as herein set forth.
metal first in Wearing contact with the Journal will automatically adjust and fit itself thereto, while the form of the harder-metal part of the bearing which supports the softmetal part will not be crushed or changed by reason of the load-pressure. The form of the said ridges or spurs and of the recesses is of little importance, except as a matter of convenience in their formation, and their longitudinal direction may differ very Widely from that of the ljournal to Which the bearing is applied Without practically impairing the value for the purposes for which they are employed, provided the metal forming the ridges or spurs is of a soft or yielding nature and is applied to the hard or unyielding portion of the jour- The ridges of soft metal may be intercepted by transverse ridges or stops e, for limiting the flow of the lubricant toward either end of the grooves in which it is placed.
The hard or unyielding body or portion of l the journal-bearing which carries the ridges of soft or yielding metal upon its journal side is seated in an iron easing or housing7 B, as illustrated in Figs. l and 3.
Having thus described my invention, what I claim is- A journal-bearing made of two different metals, one of a soft or yielding nature and the other of a hard or unyielding nature, the soft or yielding carrying ridges or spurs which receive the initial pressure of the journal, and by the rolling action of the same and the loadpressure upon the bearing become crushed down and spread in conformity with the contour thereof, as described, whereby the surfaces in wearing contact are adjusted to each other, substantially as speciiied.
