CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 370,088, dated September 20, 1887.

Application filed June 1S, 18E?. Serial No. Qfilffl. (No model.)

To aZZ whom, it may concern:

Be it known that I, HAMILTON RoGERs, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have 5 invented certain new and useful Improvement-s in Car-Axle Boxes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains ro to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

y My invention relates to an improved oaraxle box, and has for its object to provide means by which the packing necessarily employed shall be retained in its proper relation to the journal; also, to prevent dust from entering the box and mixing with the lubricant 2o contained therein; also, in providing a dripbox,into which any of the lubricant that may travel along the journal may be led therein and saved. l have also provided a scraper intermediate the rear end of the journal-bearing and box, so pivoted as to allow a semirevolution to conform to the direction of revolution of the axle, thereby tending to prevent escape of the lubricant in the direction of the length of the axle, and tending to return the 3o same to the oil-receptacle in the box. l have also provided a peculiar and valuable form of packing particularly adapted to my form of car-axle box, as will more fully appear in the description.

In the drawings, Figure 1 represents a longitudinal sectional View of my improved device. Fig. 2 is a cross-sectional elevation of the same on the line x, Fig. l. Fig. 3 is a detail View of my improved dust-board.

o Like letters of reference indicate like parts throughout the several views.

A designates the car-axle; B, the bearing; C, the wedge. These parts are of the usual construction, and therefore need no further .1,5 description. p

D represents the upper,and G the lower, por tion of a dust-board adapted to encircle the axle within the box and prevent the ingress of dust to the lubricant. The part D is preferably formed of a width suflicient to allow the formation of grooves E, into which side portions, F F, of the part G slide, F F being of sufficient length to extend past the Lipper end of the part D and enter perforations J of a spring, H, loosely retained in place upon the upper end of part D, and are held under the tension of spring H by gibs or keys K, or in any other preferred manner.

M is a scraper journaled in the part D of the dust-board by means of rod. L, passing 6o through the saine. The rod L extends upward from the part D a sufficient distance to allow spring H (which has a central perforation) to be held in place thereby. rlhe part D is cut away sufliciently to allow the scraper to rest therein and to be held into frictional engagement with the axle.

Q is a box supplemental to and formed beneath the main box, and is preferably cast in` tegral therewith. Upon its under side is fast- 7o ened a spring, U', having a catch, U, for the purpose of holding a drip-pan or lubricantreceptacle, T, in its proper place within box Q.

R is an inclined cut-away portion of the main box, adapted to lead any of the lubricant that may escape upon the axle into the drippan T as the same may drop onto the inclined projection S of the box Q.

P are longitudinal ribs or projections upon the bottom of the main box. These ribs 8o have communicating passages O, through which the lubricant may ioat to maintain an even height in the box. These ribs are for the purpose of retaining the packing P in place and preventing the same from moving in the direction of the rotation of the axle so far from the center of the box as to lessen, if not altogether stop, the feed of lubricant by capillary attraction.

In the packing shown in Fig. l I have illustrated an improved means of insuring an even feed of the lubricant, in which I employ metal shavings, P', which, by their elasticity, tend at all times to hold the cotton-waste, or any brous material that may be incorporated therewith, into engagement with the axlejournal; or, if preferred, the metal shavings alone may be employed. It will be seen that this feature is of great value, when it is considered that the cotton-waste usually em- IOO ployed, when saturated with lubricant, is of such density and weight as to fall below the position within the box. The dust-board is ad justed around the axle by inserting the parts F of the bottom portion, G, through the perforations J of spring H, and are held in place by gibs or keys K, by which means the dustboard at all times is caused to encircle the axle and to be held into frictional engagement suciently to prevent the ingress of dust. At the same time, by the attachment of these parts through the medium ofl spring H, they are allowed to yield to the motion of the axle. When the dustboard is in position, as described, the scraperM is brought to b ear upon the axle between the dust-board and bearing B, the outer end of the scraper radiating toward the inner portion of the box at all times, without reference to thedirection of rotation ofthe axle, as the friction upon the scraper M revolves the same to correspond with the direction of the axles rotation, the inclined por tions of the cut-away part of the dust-board allowing the scraper to rest in an inclined relation to' the length of the axle, thereby tending to lead the lubricant that may be upon the axle back to the main box. The packing, 'composed of metal shavings or metal shavings wound with cotton-waste, is held from lateral displacement by ribs P, and any of the lubricant that may have passed the scraper and dust-board is led down the side of the main box into the drip-pan-T to be again emptied into the main box, thereby not only effecting a great saving in lubricant, but preventing the ow of the same upon the wheels of the train and other parts of the running-gear of the cars.

My improvement can be attached to the present forms of car-axle boxes With butslight expense.

Having described my invention, what I claim, and desire to secure by Letters Patent,

l. In a car-axle box, a pivoted scraper adapted to automatically adjust the inclina` tion of the saine toward the box and in the direction of the rotation of the axle, as and for the purpose set forth.

2. A flexible packing for car-axle boxes, composed in whole or in part of metal shavings, and meansfor holding the same in frictional engagement with the axle-journal, as and for the purpose set forth.

3. A car'axle box provided with a supplemental removable drip-pan and means for leading the escaping lubricant therein, as and for the purpose set forth.

4. In a car-axle box, a dust-board having av scraper pivoted therein. adapted to rest upon the axle, as and for the purpose set forth.

In a car-axle box, in combination with a car-axle, a sectional dust-board embracing the same, formed of an upper section provided with grooves, a lower section having side portions adapted to slide within the grooves in the upper section, a half-elliptic spring resting upon the upper section, and having a perforation in its center by which it is retained in place by means of -a rod passing through the same, and perforations at each end through which the side portions of the lower sections pass, and are held in place by keys, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereby affix my signature in presence of two witnesses. v

HAMILTON ROGERS.
