CHARLES P. HOLMES, OF GOUVERNEUR, NEW YORK.

CAR-AXL LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 273,991, dated March 13, 1883.

Application tiled February 13, 1883.

tain new and useful Improvements in Itailway- Car-Axle Lubricators; and I do hereby declare that the following is a full, clear, and exact i description of the invention, which will enable others skilled in the art to whichit appertains to make and use the same,reference being had to'the accompanying drawings, which form a part ot' this specification, and in which y Figure l is a longitudinal vertical section of my device, showing the car-axle in elevation.`

Fig. 2 is a vertical cross-sectionof the same through line x a; inl Fig. 1. Fig. 3 is a perspective view of one of the chairs, with its springrollers and pick-up chain removedfrom the axlebox. Fig. 4 is a perspective view of a pair ofthe rollers withthe chain removed. Fig. 5 is a longitudinal sectional view through the rollers. Fig. 6 is a perspective view of one ofthe roller-supporting springs or spring-bearings detached from the chair, and Fig. 7 is a detail view of the upper end of the spring-bearings, showing the manner of fastening them to the roller journalshafts.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of devices for lubricating the axles of railwaycars in which the oil or other lubricant is fed to the axle byrollers journaled in spring-bearings, so as to cause them to bear against the under side of the axle within the axle-box, in conjunction with an endless pick-up chain, which is carried round by the roller-shaft and dips with its free end in an oil cup or reservoir located. in the bottom of the ,axle-box 5 and my improvements consist in the novel construction and arrangement of operative parts, as hereinafter more fully described and.` claimed, wherebyI prevent jumping of the pick-up or feeding chains in running the cars over rough roads, andwprovide for the satisfactory working ofthe device under all conditions and circumstances.

` In the accompanying two sheets of drawings, A denotes the journal-box, which may be of any approved construction. In practice, I prefer to construct my improved lubri- (No model.)

eating device so that it will fit the journalboxes adopted `by the Master Car-Builders Associatiomlso that it can, be readily fitted into these boxes; but it is obvious vthat it may "be made tofflt boxes of any special pattern or construction. In the bottom of the box is the oil-reservoir B. y

C denotes the journal; D', the journal brass or bearing, and E is the journal-'box cover. When adapted for use on `street-cars or elevated-railway cars, my device is of course con. V

structed of such size and shape as `to t the boxes usedon that particular class ofl cars.

ln the bottom of the journal-box are placed two chairs (shown atD D) ot identical size, shape, and construction, arranged, side by` side, crosswise in the bottom of the box, but

in reversed positionth atis, with their springseats at opposite sides. Each chair is in the form of a rectangular box ot' a length corresponding to the inside width of thejournalbox and cut away on its under side, as shown at a, to form arched ducts for the free passage of the oil from 'one end of the box to the other. The chair is cast with thespring-seat E at one end and two vertical lugs or projections, F, in the opposite corners, which, by bearing against the sides of the box, as shown in Fig. 2 of the drawings, prevent tilting of the chairs by the rapid revolutions ofthe axle or jumping ot' the cars. The two chairs are united on theirsides facing each other by pins b, andare held in place inside ot' the box besides by the end lugs or projections, F, by means of a springbail, G, having coils g, the lower end of which is fastened in ears c in one of the chairs, while its free upper end bears against the top ofthe box,just backof the hinged cover E. Thusit will be seen that no screws orbolts are used to hold the device in place withinthejournalbox, but that it can be inserted and again `readily removed, when desired, without in theleast disturbing or altering the construction of the IJO at e e, to hold the yokeI in place. In the free end of arms H H is lxed .a short shaft or journal, K, on which rollers L L, united by the short tubular shaft M, are journaled. The sides of the rollers facing each other are rounded to form an ogee curve or rim, l, and the short shaft M between them is recessed to form ribs or raised parts m, which engage the links of the endless feed-chain N, the lower free end of which dips in the oil in the bottom of the box. By this construction I 'prevent slipping ofthe chain, and by the peculiar curve or rounding of the inner faces of the rollers the chain is prevented from being carried over o r jumping the rim ofthe roller by the jolting of the'car, but will-always drop back into its proper position between the rollers, as the links cannot catch on the ogee-cnrved rim l.

The chairs D are ot' such a width that the rollers journaled in the free ends of the springarms H may be depressed down between the sides of the chairs without interfering with'or striking` against the chairs, and by the arrangement of the wire bearing with its shoulders h h the arms are brought so low that their free ends can never come in contact with the axle. Again, by constructing al separate chair for each pair of oiling-rollers, the rollers of one chair cannot come in conflict with those of the other; nor can the feed-chains become entangled, as Where both sets of rollers with their respective chains are mounted in the same chair. AvThis construction of the chairs and rollers, with their appurtenances also, (as has been already stated,) permits of the easy insertion of the chairs into the journal-box without disturbing any of its parts. Y To prevent the upper ends of the wire arms H H, where these are fastened in the rollerjournal K, from being broken bythe knocking against them of the rollers or sudden jerks of the cars, I insert that part of each arm through a tube or sleeve, 7a, by which the wire is reenforced and its strength and durability greatly increased. This also prevents contact between the rollers and arms between which they are hung, which is apt, by the rapid revolutions of the rollers, to cut the wire arms, and thus render them useless.

Another important advantage which results from my improved arrangement of the oilingrollers in separate chairs is, that the axle-jourvoir.

nal is oiled in four different places, instead of only two, thus throwing up a much thicker lm of oil against thejournal, over which it is distributed evenly by the bearing-brass which' It is obvious that this device may be applied to shafting and the journals of machinery generally as well as to the journals of Iocomotives and railway-cars. l

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States y 1. The combination, with thejournal Gand journal-box A, of the two chairs D D, placed, side by side, crosswise in the bottom of the box, and connected on the sides facing or impinging upon each other, each chair having structedwith the spring-seats E, having notchesl e, corner lugs or projections F, and arched oilducts a, substantially as and-for the purpose shown and set forth. v

4:. The yielding roller-bearings constructed with the parallel arms H H, spring-coils I, and yoke J, in one piece,.and having shoulders h h where arms H leave the spring-coils, substantially as and for the purpose shown and set forth.

5. The combination of the chairs D, having seats E, notched atc, and yielding roller-bear- IOO ings consisting of the parallel arms H, spring- Y ycoils I, shouldered at h, and yoke J, all in one piece, and adapted to tit the notched seat of the chair, substantially as and for the purpose shown and set forth.

6. The combination of the yielding rollerbearings H,reenforcing sleeves k, roller-shafts K, and rollers L M L, substantially as and for the purpose shown and set forth.

7. The oiling-rollers L, having an ogee annular curveor bevel, t, on the sides facingthe feed-chain N, substantially as and for the purpose shown and set forth.

S. The combination of the journal-box A, chairs D, provided with the spring-supported rollers L M L, having feed-chains N, and bailfastening G, bent to form the spring coils or loops g, and bearing with' its upper free end against the roof of the journal-box, substantially as and for the purpose shown and set forth. y i

In testimony that I claim t'ne foregoing as my own/I have hereunto affixed my signature in presence of two witnesses.
