LU BRICATINVG JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 602,959, dated April 26, 1898.

Application iiled July l, 1897. Serial No. 643,084. (No model.)

box in actual practice Was found to be objec` tionable in that the jolting of the cars and 'the rotation of the journal would splash and carry oil to a point above the sides of the reservoir, and this oil would run down the sides of the axle-box externally of the reservoir and make the same and the interior of the axlebox dirty and filthy in an undesirable degree.

tain novel and peculiar features of construe' tion and combinations of parts, as will be hereinafter described and claimed.

In order that the invention may be fully understood, I will proceed to describe it With reference to the accompanying drawings, in Which- Figure l represents a central vertical longitudinal section of a car-axle box and a lubricating journal-box embodying my invention. Fig. 2 represents a section taken on the line Il II of Fig. Fig. 3 represents a v section taken on the line Ill III of Fig. l.

In the said drawings, l designates a caraxle box provided with the customary door 2 and with a large opening 3 in its front end below said door. The side Walls of the box are internally provided with inwardly-proj ecting deiiecting-ribs 4, fora purpose Which will be presentlyT explained, o designates the journal of an axle, projecting into said box and arranged in the customary manner.

6 designates the reservoir of the lubricating journal-box. It is of elongated rectangular form, so as to fit snugly between the side Walls of the axle-box, and of a lengthl to extend from the back wall, which it abuts against and overlaps, to thefront end of the axle-box, of which end it forms a part, it being rounded at its lower end, as at 7, and extended or iianged upwardly, as at 8, to the plane of the deflecting-ribs 1l. Said rounded and hanged end 7 and 8, respectively, of the reservoir fits snugly in and closes the opening 3 of the axle-box, as shown clearly in Fig. l. The Weight of the door and the pres sure of its actuating-spring, which isshown, but not described, as it is of the customary form and arrangement, is adapted to hold the reservoir in proper position in the axle-box, and it will be obvious that when said door is opened the reservoir may be easily slid from position, owing to the fact that when the door is open there is no front end to the box except that formed by the reservoir, and consequently there is no lifting or tilting required to remove the latter.

The reservoir, near its front end, is pro-V vided With an opening through which it may be supplied With oil Without removing it from position, and said opening is normally closed by means of a screw-plug 9, and it is also provided centrally With a longitudinal slot or opening 10 in its upper side, the rear end of said slot being coincident with the rear Wall of the reservoir and its front end vertically below the end of the journal, at this point the reservoir being provided with a depending vertical ilange l0 for a purpose which will presently be explained. The top wall, for about the length of said slot, slopes down- Wardly and inwardly, as at ll, so that any oil which may drip thereon will be conveyed back into the reservoir through said slot or opening l0, and it is also provided With'the transverse slots l2, through which pins or hooks (not shown) may be inserted when it is desirable or necessary to adjust the Wicks, as hereinbefore referred to. The reservoir is also provided centrally With a guidewrib '13, projecting vertically upward from its bottom.

IOO

14 designates the wick-tube, which is ofV V jects, and thereby insuresa direct vertical movement of the wick-tube when adjusted automatically to accommodate the Wear upon the wicks. Said tube is provided at its opposite ends and in its under side With one or more cavities 17, Within which iit snugly expansive springs 18, coiled aroundV the guidepins 19, projecting upwardly from the base and centrally of said cavities. These springs tend constantly to elevate the wick-tube, and the only restraint upon such movement is due to the fact that the Wicks 20 bear firmly against the journal at their upper ends. As such ends wear by frictional contact With the j ournal the wick-tube is automatically lifted by said springs and a constant contact thereby maintained between the wick and the journal.

VThe back wall of the reservoir and therdepending flange 10 at the opposite end of the guide-tube assist the guide-rib 13 in maintaining the wick-tube in its vertical position, so that the sprin gs shall always be free to perform their proper function and the Wicks, consequently, always in engagement With the journal.

Owing tothe fact Vthat the back wall projects above the top wall and that the flange 8 projects also above the same, it is obvious that the rocking or oscillatory movement of a car cannot cause the surplus oil, Which may splash up through the openings 10 or 12 or be carried up by the journal and by centrifugal force discharged against the side Walls of the axle-box above the dellector-ribs 4, to escape past the ends of the reservoir, nor will such movement materially retard the rentrance of the oil to the reservoir in the manner hereinbefore explained.

From the above description it will be'apparent that I have produced a combined car axle and lubricating journal-box which insures proper lubrication andan economic use of oil and which is simple, strong, durable, and inexpensive of manufacture, and it is to be understood, of course, that these lubricating journal-boxes I design for use in connection with locomotivejournals orin connection with the journals of'any style of vehicle to which it can be applied Without necessitating such changes as would be a departure from the spirit and scope of the invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A lubricating journal-box, comprising a reservoir provided with a centralV slot or opening in its top wall, a depending ilange at one end of the same., and a vertical longitudinal rib projecting upwardly from its bottom and centrally of said slot or opening, and a vertically-adjustable Wick-tube fitting snugly in said opening and provided with a recess 16 into which said guide-rib projects, substantially as described.

2. In a device of the character described, the combination with a car-axle box provided with an openingin its frontend below its door, and horizontal ribs projecting internally from its sides coincidentally With the upper edge of said opening, of a lubricating journal-box fitting snugly within and upon the bottom of the car-axle box and provided with a rounded end and flange closing the opening in the front end of the box, and provided with a central slot or opening, and with a central rib projecting upwardly from its bottom; a double wick-tube fitting snugly in the slot or opening and provided with a recess fitting on said rib; and springs bearing upon the bottom of said box and exerting a const-ant upward pressure upon said tube, substantially as and for the purpose described.

In testimony whereof I affix my signature in the presence of two witnesses.

JOHN ROGERS.
