JOSEPH E. DOWNER, OF ALLENPORT, PENNSYLVANIA.
ANTIFRICTION-BEARZING.
Application filed May 29,
Specification of Letters htent.
1908. Serial -No.-436,766.
' Eatented May'25, 1909.
To all whom it may concern:
Be it known that I, JOSEPH E. DOWNER,
citizen of the United States of America, re-
siding at Allenport, in the county of VVashington and State of Pennsylvania, have invented certain new and useful Improvements in Antifriction-Bearings, of which the following is a specification, reference belng had therein to the accompanying drawing' ]ing adapted to be used in the ,journal boxes it cars. 4 he invention has for its primary object to provide a novel form of bearing not necessitat'ing the use of a lubricant, wherein novel means is employed for removing all dirt and dust from the journal box in connection with which it is used.
Another object of this invention is to provide a novel form of bearing for thespindles of axles or for shafts which will be extremely simple in construction, strong and durable, comparatively inexpensive to manufacture and highly efiicient for the purposes for which it is used. Y
With the above andv other objects in view, which will'more readily appearas the nature of the invention is better. understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described and claimed, and referring to the drawing accompanying this application, like characters of reference designate corresponding parts throughout the several views in which:
Figure 1 is a vertical sectional view of a journal box equipped -with my improved bearing, Fig. '2 is a longitudinal sectional view of the same, Fig. 3 is a side elevation of a roller illustrating a slightly modified form of construction. I
In order that the a plication of hey improved rollers to a sha t or spindle of an axle may be fully understood, I have illustrated in the accompanying drawing, a conventional form of Journal box as cominonlycarried by an ordinary type of pit car, the, j'our inal box forming an annular opening 2 into which the spind e 3 of an axle 4 extends the axle being provided with an annular collar 5,
which heretofore limited the movement of the s'indle within the journal box and serve functionally as a dust guard.
I My invention resides in the use of a plu l rality of rollers within the journalbox A, half of said rollers being of greater diameter ers. The main rollers 1, which in the present instance are four in number, are formed with a cylindrical bodytportio n 5 having coneshaped ends 6, 6. 'lhe rollers are preferably be hardenedv to withstand the wear and tear to which they are subjected; rollers 7, as they will be hereinafter termed, are also four in number and are of a less diameter than the main rollers 1", 1'. The spacing rollers 7 are formed of a cylindrical center portion 8 and cone- shaped ends 9, 9 similar to the main rollers 1, 1. All of the rollers, eight innumber, are adapted to bear upon the spindle 3 of the axle 4, while the collar 5 of the axle 4 and a plate 9' secured to the journal box A. The-collar 5 and the plate 9, are adapted to take up the end thrusts of my improved rollers.
A modified form of spacing rollers is illustrated in Fig. 3 wherein the contracted cenlen th than the central portion of the roller 7, Wlll e the ends oft-the rollers '12 are more abruptly tapered, than the cone-shaped ends of the spacing roller 7. By the novel construction of my improved I rollers it is not essential that a lubricant be used in connection with the same, although if a lubricant is used, a very small quantity will suffice in maintaining a'perfect bearing of the spindle 3 within the journal .boxA
I do not care to confine myself to the number of main rollers or spacing rollers used in a journalbox or to theirrsize, proportion and minor. details of construction, and such changes as are permissible by the appended claim, may be resorted to without departing from the spirit and scope of the invention.
What I claim and desire to secure by Letters Patent,-is:- i
In a roller bearing, the combination with a spindle, a journal box receiving the s indle, a bearing-collar mounted on the spind e, and an end plate for the goumal box, said end plate receiving a spin lo and also constitutthan the other of said rollers, the latter serving functionally as spacers for the inain roll-v constructed of the best of steel, which may;
The spacing body portion. having an annular contracted,
mair1 1'ollers 1-, 1 only bear against the inner walls of the journal box A. The cone-shaped ends of the rollers are adapted to engage the ter portion 11 of the roller 12 is-ofa greater in a bearin plate, of a pluralitycf main journal box and having reduced central por- '10 r0 ers space apart and peripherally engagtions.
I against said bearing collar on the spindle and bearing plate of the journal box, and spacingv ing the lslpindle and the journal box, \said' In testimcny whereofl affix my signature: main r0 ers having conical ends {"Sfifillfid in the presence'of'twc witnesses.
