CHARLES A. HASKINS, or oIIIc eo, ILLINOIS, ASSIGNQR or ourgggjumn on HIS RIGHT TO ELL AII SMITH, or SAME PLACE:
IMPROVEMENT CANR-AXLE Boxes.
To whom it may concern:
Be it known that I, GHARLEs A. HAsKINs, of
' Chicago, inthe county of Cook and State of Illinois, have invented a new and useful Improvement in an Anti-Friction J ournal-B ox; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which Figure 1 is a cross-section through my im proved journal-box and its journal. Fig. 2 is a longitudinal section of the box, the anti-friction rollers and their rings being removed. Fig.
3 is a sectional end elevation of the anti-fric tion rollers and the slotted ring which holds them in place. Fig.4 is an elevation of the edge of one of these rings with the ends of two rollers in place, and Fig. 5 is ahalf elevation of one of the lateral motion gates.
Similar letters of reference indicate corresponding parts in the several figures.
The nature of this invention relates to an improvement in that class of journal-boxes in which a series of anti-friction rollers is interposedbetween the journal an d its bearing; and it consists in the peculiar device for lubricating the journal, rollers, and bearing; and in the peculiar gates employed for keeping the journal in the box, while allowing it sufficient lateral movement to accommodate the gauge motion of the wheels and axle, the whole arranged and operating as more fully hereinafter set forth.
In the drawing, A represents the journal of a car-axle, and B is a square axle-box, cored out in molding, and bored out to receive the journal, but of sufficient diameter to allow of a series of encircling anti-friction rollers, G, to be interposed between them. These rollers have a journal, 0, turned down at each end, which is received in a bearing formed at the bottom of one of the radial slots in a ring, D, at each end. These rin gs keep the rollers in position around the journal, and thewhole series revolved slowly around the journal in the rotation of the latter, thereby producing only rolling friction betvgeen the journal and the bearing in the box, the advantage of which is too well understood to enlarge upon.
To lubricate the moving parts Iform a cham- Specification forming part of Letters Patent No. 127,163; dated May 28, 18 72.
ber or compartment in the lower part of the box for the reception of oil which is contained in a drawer, F, of sheet metal, which may be it nearly in contact with the lowermost roller above it. The plate G is perforated and covered with felt g on the top and ends, which felt cover is touched by each one of the rollers in the rings as it revolves by, and lubricated thereby, the oil being drawn up from the pan by capillary attraction, and thus supplied to therollers, which, in turn, lubricate the journal and the bearing.
To keep the journal in its bearings and still allow the necessary lateral play to ease up the gauge motion, I turn down in the outer end of the journal an annular recess, 01, leaving a collar, d, at the extremity of the axle. In the outer part of the shoulder of the axle I turn down a similar groove, leaving a like collar .of the gates and width of recess or grooves 01 is the play given the axle, as seen in Fig 2, and may be varied to suit circumstances. The
gates may be secured by a single bolt through a lug at each end of the top of the box.
By removing the cover H of the box and withdrawing the gates, any one or all of the rollers may be replaced in the rings by others without necessitating the removal of the axle, only requiring the box to be jacked up enough to relieve the pressure of the car on the rollers.
kind is required to insure the lubrication of the moving parts, with the exception of the light strip of felt mentioned and shown 5 consequent No cotton-waste or other material of the ly, Where my improved journal-bearing is used there will be a large saving effected in this item alone, independent of the great reduction in friction, and the renewal of brasses, as compared with the axle-boxes hitherto generally used.
In order that the felt strip may be touched by each successive roller as it revolves about the journal, the bore of the bearing in the box has cut throughits bottom a longitudinal opening, as shown in Fig. 1.
What I claim as my invention, and desire to secure by Letters Patent, is
1. The drawer or oil-receptacle F, perforated plate G, and felt strip g, in connection with the series of rollers G and rings D, as and for the purpose set forth.
2. The construction and arrangement of the box B, rings D, rollers 0, cover H, drawer F, perforated plate G, felt strip g, and gates E, in connection with an axle-journal having the grooves d and collars (1 formed thereon, as
and for the purposes set forth.
