CAR-AXLE BOX.

lVCi'-EATON forming part of Letters Patent No. 318,879, dated Ivl'ay 26, 1885.

Application tiled February 12, 1835. (No model.)

To @ZZ whom, it may concern.:

Be it known that we, GEORGE E. DE GRANGE and firman G. GREEN, citizens ofthe United States, residing` at New Orleans, Louisiana, have invented new and useful Improvements in Car-Axle Boxes, of which the following is a specication.

Ourinvention relates to that class of caraxle boxesin which the journal of the axle revolves in a chamber containing the lubricant and asuitable vehicle-such as tow or cotton or other medium-#for feeding thelubricant to the j ournai.

The object of the invention is to provide simple and effective means for excluding dust and grit from the interior of the box, therebyr preserving the oil or lubricant in a free and clear condition, so that there will be no appreciable wear of the journal and the brass or bearing. The invention also has for its object to prevent the loss of oil at the front of the box where, asin ordinary boxes heretofore devised, the oil is liable to escape through the joints between the cover and the box.

To these ends the invention consists in fitting a cup-shaped annular flange on the axle of the wheel and providing the rear end of the axle-box with a boss carrying a collar, which fits into or is inelosed by the annular flange on the axle. Said collarbears a packing-ring upon its outer face,which rests against the bottom ofthe cup-shaped annular flange, so that the parts thus 'fitted will efectually prevent the entrance of dust or grit into the oil or journal chamber.

The invention also consists inlocating a vertical division-plate at the frontof the oil-chama ber of the axle-box, said plate extending from near the iloor of the chamber up to the under side of the journal of the axle, and being arranged at the inlet opening or mouth of the axle-box. The object of said plate is to arrest the outward low of the oil caused by jolts or concussions when the car is turning curves, or

from other causes, thereby preventing the oil' from being thrown against the axle-box cover and leaking` out through the joints. Said stopplate does not extend to the bottom of the oilchamber, and hence the latter can be replenished with oil by causing the same to flow under the plate.

In the drawings, Figure 1 is a longitudinal section of a car-axle box embodying our ilu- Vprovenients. Fig. 2is a detail view ofthewheel,

axle, and cup-shaped tlange on said axle.l Fig. 8 is a rear view of the axle-box, representing` the collar and packing-ring applied thereto.

The referenceuiumeral l designates an axlebox, which is made of cast-iron in the form and manner usually employed lfor this purpose, and is fitted in an appropriate hanger or pedestal, so as to slide up and down as the customary pressure-springsV contract or expand. A bearing or box, 2, of brass or other composition metal,ts the journal 3 of the axle fl, and is provided on its back with a transverse groove to engage with a rib, 5, on the under surface of the top ofthe box, so as to prevent said bearing from moving in the direction or the length of the axle. In the front of the box is an openin g, which is closed by a lid or cover, 6, that can be removed or lifted to renew the oil or lubricant and lhe cotton waste, tow, or other medium for holding the oil and feeding it to the journal.

As sh'own in the drawings, the upper edge of the cover engages with a recess, 8, formed near the top of the box l, and its lower edge has au apertured lug, 9, through which is passed a pin or screw, 10, that enters a seat or socket, 11, on the box and holds the cover in position.

At the sides of the opening or mouth ofthe box are formed guideways for the reception of the detachable plate 12, which, when in position, bears against the front end of the axlejournal, so as to prevent thelongitudinal movement thereof.

All the parts above designated are similar to those used in axle-boxes heretofore devised, and form no part of our invention.

At the freut of the oil or lubricant chamber and a short distance from the solid front wall, 13, disposed below the mouth or inlet opening, is located a transverse plate, 14, which rises from near the bottoni of the oil-chamber to a. point immediately below the Linder side of the journal of the axle. Said plate 14 is generally inclined in an inward direction from the front of the axle-box, and a space or filling chamber, 20, is thus left between the front wall, 13, and said plate 14. Then oil is poured into said space 20, it will flow under the plate 14: into the lubricatingchainber, as will readily be ap- IOC flange can form an integral part of the car- Wheel16 by being east on the inner face thereof. On the rear face or Wall of the axle-box is formed a hub or boss, 17, which has an outer collar or ring-plate, 18, made of such size as to fit into the cup-shaped angeand plate on the axle, but being smaller than the seat-space in said eup'sh'aped flange, so that they latter can vrevolve around the ring-p-late 18 Without frictio-n against its periphery. The inner face of the ring plate or collar 18 carries a-n elastic or other suitable packing-disk, 19, which bears against the bottom ofthe cup-shaped fla-nge and prevents access of dirt and grit to the axle passing through the packing-disk 19, plate 18, and hub 17.

By providing an axle-box with our attachments-abovefully setforth we efteetually guard against the leaking ont of the oil through the front and rear of the box, and also prevent the entrance of dirt and grit into the interior of the box, thus preserving the bearings and journals intact for a vastly longer period than is the case with the axle-boxes heretofore known.

What we claim ism 1. The combination ofthe axle-box provided with the hub or boss 17 formed integral with the annular metallic disk 18, with the flexible packing-disk 19, attached directly to the inner face of the metallic disk, the axle, the wheel, and the cup-shaped annular ange 15, substantially as described.

2. The car-axle box provided with the transverse division-plate 14, having its upper and lower horizontal edges terminated, res-peetively, 'at a distance from the car-axle and the bottom wall of the box, substantially as and for the purpose described.

In testimony whereof Weafix oursignatnres in presence of two Witnesses.
