SPECIFICATION forming part of Letters Patent No. 558,329, dated April 14, 1896.

Application nea August 3o, 1895. serial No. 560,972. (No model.)

T all whom it may concern:

Beit known that we, HENRY P. VEALE and GEORGE L. ADAIR, of Boston, in the county of Suifolk and State of Massachusetts, have invented certain new and useful Improvem ents in Self-Lubricating Car- Axle Boxes, of which the following is a specification.

This invention relates to a car-axle box which is provided with an oil-chamber below xo the journal of the axle and with means for continuously raising the oil into contact with the journal.

The invention has for its object, first, to provide an axle-box with improved means for i 5 excluding dust from the journal and from the oil-chamber, and, secondly, to provide an improved oil-feeding device adapted to be applied to an axle-box of ordinary construction and to be readily removed from the box.

zo To these ends'the invention consists in the improvements which we will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure l represents a longitudinal section of a car-axle box provided with our improvements. Fig. 2 represents a section on line 2 2 of Fig. l. Fig. 3 represents a perspective view of the lubrieating attachment removed from the axle- 3o box. Figs. 4 and 5 represent perspective views showing the parts of the dust-guard.

' The same letters and numerals of reference indicate the same parts in all the figures.

ln the drawings, a represents a car-axle 3 5 box, which may have the ordinary general form, it being open at its inner end for the reception of the axle b and having an opening a at its outer end aording access to the interior of the box, said opening having the 4o usual detachable cover CL2.

The box is of sufficient depth to provide an oil-chamber a3 below the journal b of the axle, the opening a' being above said chamber and communicating therewith.

So far as the features thus far described are concerned, the box is of ordinary construction, the chamber a3 being the space that is ordinarily iilled with cotton-waste saturated with lubricating material.

5o In carrying out our invention we provide at theinner end of the box two parallel walls a4 d5, eachhaving an enlarged opening a6 for the reception of the axle, said walls forming a packing or dust-guard receiving chamber a7, which surrounds the axle. The proximate sides of said walls are preferably trued to form smooth flat seats 3 4 for the dust-guard plates presently described, and the openings a6 are of sufficient size to permit the necessary independent movements of the axle and 6o box.

In the chamber 0.7 we place a dust-guard, which comprises two plates c c', each having an opening c2, formed to closely fit the axle. The outer sides of said plates are trued to 65 snugly fit the seats 3 4, thev plates being free to move with the axle, so that their outer sides are in sliding contact with the said seats. The plates c c are held yieldingly against the seats 3 4 by means of springs d d', interposed 7o between the plates, said springs being here shown as attached by the plate c and bearing at their free ends against the plate c.

The plate c is provided with a flange c4, which partially surrounds the opening c2 in 75 said plate and forms the margin of a pocket between the plates c o for the reception of fibrous packing material e, which may be cotton-waste or any other suitable material.

It will be seen that the described dust- 8o guard, comprising the plates c o', springs d d and iange c4, maintains a dust-tight joint around the axle and adapts itself readily to the relative movements of the axle and box.

f represents an arm or rod, which is screw- 8 5 threaded at its outer end and passes through a hole formed in the outer end of the box a above the oil space or chamber 0.3, the said arm being secured to the box by nuts f f2 on said threaded portion. The arm f is formed 9o to extend downwardly to the lower portion of the oil-chamber and inwardly to a point under the journal b. To the inner portion of the arm fis connected a standard f3, preferably by means of a plate f4, riveted to the inner end of the arm and constituting an extension thereof, although it is obvious that the standard may be formed directly on the arm, the latter being suitably lengthened.

To the standard f3 is pivoted a lever f5, havroo ing arms f7 f7 at each end, in which are bearings for the shaft of a roll f8. The other end of the lever f5 has a weight fg, adapted to exert an upward pressure on the roll f8. The said roll is located in the oil-chamber 0.3 below the journal b and is pressed by the Weight against said journal. The roll is therefore rotated by contact with the journal, and as its lower portion is close to the bottoln of the oil-chamber its rotation causes a continuous supply of oil to the journal, the oil being raised by the periphery of the roll and presented to the journal, which is thus kept constantly lubricated. Loss of oil from the box is prevented by the dustguard, so that a single charge of oil will last a long time.

It Will be seen that the arm f, provided, as shown, with means whereby it may be detachably secured toY the outer portion oi' the box a above the oil-cl1amber, and the roll f8, supported by said arm in the accumulation of oil in the box, constitute a lubricating attachment that can be readily applied to an ordinary axle-box and can be as readily removed for repairs, no adaptation of the box being required other than the formation of the hole for the reception of the outer end of the arm f.

We claiml. A car-axle box having the parallel walls a4 a5 at its inner end, each having an opening for the reception of the axle, said walls being separated by a packing space or chamber;

combined with a dust-guard comprising, first, a plate c loosely seated on one side of said chalnber and having an orifice closely iitting the axle and a packing-retaining ange partly surrounding the axle; secondly, an independent plate c' loosely seated on the opposite side of said chamber and having an orifice closely iitting the axle, and thirdly, springs interposed between the plates c and c and pressing said plates against their seats.

2. A lubricating attachment for car-axle boxes, the same comprising the arm f provided at its outer portion with means such as a screw-thread and nuts, whereby it may be detachably secured to the outer end of an axle-box, and at its inner portion with a standard f3; a lever pivoted to said standard and provided at one end with roller-bearin gs and at the other end with a weight; and a lubricating-roll journaled in said bearings and pressed upwardly by the said weight, the arm being formed to hold the roller in position to bear yieldingly against the lower portion of the journal.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 5th day of August, A. D. 1895.

HENRY P. XVEALE.

GEORGE L. ADAIR.
