D H. DOTTERER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGN OR TO HIM- SELF AND DILLWYN PAR-RISE, JR, OF SAME PLACE.
Letters Patent No. 65,797, dated June 18, 1867.
ea .fidgshuh marsh in in tlgrst gram new amt taking part at the same TO ALL WHOM IT'MAY CONCERN: y
it known that I, D. H. DOTTERER, of Philadelphia, Pennsylvania, have invented certain improvements in Axle-Boxes; and I do herebydeelare the following to be a full, clear, and exact description of the same, reference being hadto the accompanying drawing, and to the letters of reference marked thereon.
Myinventionrelates to an improvement in that class of axle-boxes in which an annular bearing passing around the journal and round a roller is used, my improvements, which are fully describedhereafter, being such that a thorough lubrication of the roller-spindle is effected, and other advantages, rendered apparent hereafter, attained. v
a In order to enable others skilled in the art to make and apply my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part .of this specification, and in which- Figure 1 is a vertical section of my improved axle-box.
Figure 2, a transverse section on the line 1-2, fig. 1.
Figure 3, a sectional plan view on the line 3-4, fig. 1.
Figure 4, a perspective View of part of my improvement; and
Figure 5, a front view of the box.
Similar letters refer to similar parts throughout the several views.
The case A is of the shape, or approximates to the shape shown in figs. 2 and 5, and is open at the top, where it is provided with a cover, 21, secured by bolts 0 c. 'In the bottom of the case is formed a cavity, 11, which I prefer to make of the semi-cylindrical form represented, and the object of which will be rendered apparent hereafter; Two openings,f and g, one above the other, are formed in the front of the box, and each of the said openings is closed by a cap. A roller, B, together with the annular bearing 0, is introduced into the case frgm v the top, the roller being almostas wide as the interior of the case, and being cast hollow, as shown in figs. 1 and 2. The hub h of the roller is formed'in two parts, so as to leave anannular space, i, in the centre, for a purpose rendered apparent hereafter, and in each side of the roller is a number of openings, jj. A bush, I), is fitted to the hub of the roller, and is introduced to its place through the opening 9 in front of the case. The cap it, fitted into the opening g of the case, is secured in its position by suitable bolts Z, and in a circular recess in this cap fits one end, 112, of the pin E, which is prevented from turning by a projection on the cap adapted to a groove, 1), on the under side of the pin, the opposite end of the latter resting in a recess formed in the case. Along the upper surface of this pin is cut a groove, (1, for a. purpose explained hereafter. The bush D, which, together with the roller B,'tur,ns on the stationary pin E, is somewhat longer than the roller B, and projects at one end into a recess in the case,'and at the other end into the opening g, the cap 70 preventing any longitudinal movement of thebush. The space i and holes 1', which are drilled in the bush, aflord a passage for the oil to the stationary pin. The journal X of the axle is introduced as usual through the rear of the box, which is provided with the ordinary packing, and an end bearing G fits snugly in the opening f of the case A, projections a s, fig. 3, of the bearing maintaining the journal in its proper lateral position. A portion of a cap, T, which is bolted to the case, fits into the openingf, and holds the bearing G in its place close up to the end of the journal.- As will be seen in fig. 2,7the annular bearing G passes round the journal and roller 13, the bearing points being at a; and y, Further allusion to this hearing will be unnecessary, as it forms no part of my present invention. Suflicient lubricating material is placed in the box to submerge or partly submerge the roller B, as shown in fig. 2, the sediment from the same settling in the cavity cl, whence it may be drawn oil through a hole, e. The
lubricating material enters the openings j and space i of the hollow roller B, fiows through the holes 1' of the bush 'D,and thence along the groove q of the stationary pin E, thelatter being thus thoroughly lubricated-along its entire length. It will be' evident, without further description, that by thus constructing and lubricating the bearings of the roller B, much of the friction, heat, and wear and tear caused by the great strain upon the pin E is reduced. It will also be evident that while a slight vertical motion of the axle is permitted, all-undue lateral movement of the same is eii'ectually prevented by the end bearing G.
I claim as my invention, and desire to secure by Letters Patent- '1. The hollow roller B, having openings arranged substantiaflyas;described, for permitting the lubricating material to pass through the said r0110): to the stationary pin E.
2. The said stationary pin E, andii'ts imigitndIn'al groove q, in combination with thc hollow roller and its openings.
3. The stationary pin E, arranged within tlie.box.-, a-nrd eonfin ed thereto by the, detachable can or follower k, all substantially as described.
In testimony whereof I have signedmy namerto this specification in the preseu'ce of'two subscribing witnesse D; H. DOTTERER. Witnesses:
