' ,AXLE BOX."
o.V R. CHAPLIN4 Patented Jam. 10, 18821.
UNITED STATES PATENT OFFICE.
ORRIL R. CHAPLIN, OF BOSTON, MASSACHUSETTS.
AXLE-BOX.
SPECIFICATION forming part of Letters Patent No. 252,017, dated January 10, 1882.
Application nien May 31,1880. (No model.) p
ing a part hereof, in which- Figure 1 isa section through the axis ol' a box embodying all the features of my invention in thev best form known to me. Fig. 2 is a cross-section. Fig. 3 is an interior view of the cap.
A is a journal-box, of hard compositionsuch as bronze, gun-metal, or the like-which is tted into the cast-iron box B. This box B, as shown, is adapted for use as thc axle-box of a railwaycar, but will be made for the special use required, my invention being applicable to journals or axles of all kinds.
The boxes B and A may ofcourse be made in one piece for some axles; but for railwaycars the constructionshown is preferable. `In my Patent No. 189,427, dated April 10, 1877, the box was necessarily made in two parts, because it was impossible to put the rolls and in that patent into the box endwise; and one v main purpose of my present invention is to remedy this defect, it` bein g very desirable that the rolls and their supporting-rings should be capable of being put into and taken out of the box endwise.
The rolls C are shaped as shown in Fig. 1, and are separatedfrom each other by the rolls D, and all theserolls are kept in place by the inner. and outer` rings, F Gr. The outer ring, G, is of an outside diameter not greater than the inside diameter of the box A, and the interior diameter of the inner ring, F, is greater than the diameter of the `axle H. Consequently the series of rolls C D, when arranged as shown in Fig. 2, can be inserted endwise into box A. This part of my invention consists in a bearing composed of a circle of bearing-rolls and a circle of separator-rolls held together by an inner and outer ring, (being so far much the same as in my Patent N o. 189,427, above referred to,) the outside diameter of the outer,`
*ing `\eing no greater than t diameterof a 'the box is in use.
circle inclosing and tangent to the bearingrolls, and the inside diameter of the inner ring being greater than a circle drawn within and tangent to the bearing-rolls.
For the best results the separating-rolls D should be of materially larger diameter than the smaller portions of the rolls C, and these smaller portions m ust of cou rsehelarge enough for strength.V Consequently the thickness of ring G cannot exceed, when made according to my present invention, one-halt' the difference between the diameter ot' rolls D and the larger parts ot' rolls C, and as this ring should be abundantly strong` it is desirable to m-uke it as thick as the other features of construction will allow.
, It a groove, a, be formed in the box A, the ring G may be made of an outside diameter very nearly equal to the inner diameter of the box, or so that it will just fit the boxybnt when in use this ring will not of course remain concentric with the box, and the groove u allows this motion of theaxis of ring G out of line with the axis ofthe box without bringing its outer surface in contact with the inner surf face ofthe box.
their supporting-rings constructed as shown The groove b around the axle permits the vinner ring, F, to be made of' a diameter only *a trifle greater than that of the axle, and yet prevents contact of ring F with the axle when These two featnres also constitute parts of my invention, and they are each of much practical value, as they permit the rings F andG being made abundantly strong, and much stronger than they could be made without these grooves. The end-thrust is received on a ball, J, sustained in a groove, K. L is a hardened thrust-plate or the end of the axle.
The box A, when inserted in the outer box, B, is best made as shown in the drawings;
Vbut when used without the outer box, B, the
openings a are ot' course omitted.
What 1 claim` as my invention is- 1. In an anti-friction bearing composed of the necked bearing-rolls C and separatorrolls D, the rings F and G, for holding them together, the outer ring, G, having an outer diameter no greater than the outer diameter of th e circle of bearn g-rolls, and theinner ring,
IOO
F, having an inner diameter greater than the inner diameter of the circle of bearing-rolls, as and for the purposes set forth.
2. In an axle-box with anti-friction rolls C 5 D, the ring G, of a diameter that will allow it to be inserted through the end of' the box, in
combination with the groove a in the box to prevent Contact of ring G with the box when in use, as set forth.
