IMPROVEMENT iN CAR-AXLE BXES.
Specification forming part of Letters Patent N 0. Mbdh, dated May 8, 1'877; application liled October 30, 1876.
To all whom it may concern:
Be it known that I, EDWARD L. COLMAN, of Vandalia, in the county of Audrain and State of Missouri, have invented a new and Improved .Axle-Box, of-which the following is a specification:
In the accompanying drawing, Figures l and 2 represent vertical transverse and longitudinal sections, respectively on lines y y, llig. 2, and :n x, Fig. l, of my improved axle- Similar letters of reference indicate corresponding parts.
The invention relates to an improved earanle box, with anti-friction and self-oiling` devices; and consists of the journal revolving 1n an elongated box, which is made of a top and bottom section, secured by bolted face and back plates.
A number ot' friction-rollers pass around the journal and around a guide-channel below the same, taking up the oil by a bottom inlet from the outer box.
In the drawing, A represents the outer inelosing-box, on which the truck-frame is supported, and contains an inner journal-box, that connects by a top groove, angles to the axle G, with a rounded-o' top rib, b, of the outer box. This admits the lateral motion of the journal-box independ ently ot' the outer box or easing, so as to give a certain play to the truck without straining the bearings or supports of the same.
The journallbox is made ot' a top section, B1, and a bottom section, B2, ot' which the top section is arranged at such distance from the axle-jonrnal that a space of suflcient size for the introduction 0f a number of anti-friction rollers D is provided.
Below the journal is arranged an elongated guide-block, D', which is rounded oft' at the lower part, and placed at the same distance from the bottom section B2 as the journal from the upper section. The anti-friction rollers D are thereby allowed to travel around the journal and around the guide-block, and then up again to the journal. The top and a, at right.
bottom sections Bl B2 are connected by side flanges d of the lower section, resting on lips e of the top section. The rollers D are retained in the journal-box by means ot' i'ront and rear plates E E', that are applied by fastening-screws f to the top section, and by a square bolt,f, passing` through the guideblock or partition D. Flangesg ot' the front and back plates bear on the bottom section B2, and serve to support the same. The bottom section Bz has a central oil-inlet, h, at the lowermost part, through which the oil is fed to the rollers D.
The space between the outer and inner boxes is filled up with any suitable packing that supplies the oil to the rollers, which carry it up to the journal, so as to lubricate the same and return the surplus oil to the packing' in the outer box. The supply ofthe required quantity ot' oil is thus kept up in economical and uniform manner in proportion to the speed at which the axle revolves.
The rollers feed the oil, and are placed at Some distance from each other on the top of' the journal, so as not to come in contact with each other. They remain always at a certain distance, for as soon as one is forced down on one side a roller is coming` up on the other` side.
The anti-friction rollers diminish the friction of thejournal and feed the oil in econoxn ical manner, so as to produce ear-axle box of superior quality.
Having thus described 1nyin\-'ention, vI claim as new and desire to secure by Letters PatentrIhe combination ot' the top block B1, aperture bottoni plate B2, side plates E, partition or guide-block D', and series oi' loose frietionrollers D with the external easin ,tg or box A and journal, substantially as and for the purpose set forth.
