IVMPROVED RAILROAD AXLE-BOX.

a Specification forming part of Letters Patent No. 54,563, dated May 8, 1866.

To all whom it 'may concern:

Be it known that I, JOHN J. LAHAYE, of Reading, Berks county, Pennsylvania, have invented certain Improvements in Axle-Boxes; and I do hereby declare the following to be a full, clear,` and exact description of the same, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon.

My invention consists, first, ot' the combination of an axle-box having an oil-chamber at the under side and an opening, when the said opening is situated as described hereinafter, so as to allow for the ready introductian and removal of the wick, and when the opening is surrounded bya liange, which prevents the oil from lowin g back into the chamber; secondly, ot a passage for the introduction of oil to the oil-chamber, the said passage being so arranged thatit can be closed by the lid.

In order to enable others skilled in mechanism of this class to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this speciiication, Figure lis a vertical section of an axle-box 'with my improvements, an d Fig. 2 a transverse vertical section on the line l 2, Fig. l.

A is the top of the box 5 B, the end of the same; C, the bottom, land D and D the opposite sides.

In the inside and against the top A ot' the box bears the usual detachable key E, and against the latter the bearing E', which is adapted to the said key and to the journal ct of the axle F in the usual manner.

At the rear of the box is a vertical chamber for receiving the wood packing G, which, fitting closely to the collar b ofthe axle, serves to exclude dust and sand from the box and to maintain the lubricating material within the same.

'Io lugs 'i 'i at the top, and near the front end of the box, is hinged an inclined lid, H, the cork packing It h at the back of which its against the edge of the opening in the front of the box, as seen in Fig. 1.

The lid is conned to the box by a single bolt, m, the hole a for receiving which is continued downward, so as to communicate with a chamber, p, formed in the bottom of the box for the reception of the lubricating material.

, A narrow opening, t, round the top of which extends a ange, t, forms a communication between the chamber p and the interior of the box, and through this opening passes a wick, g, one portion of which is contained in the chamber p and there immersed in the lubrieatin g material, the other portion occupying a position beneath the journal a, there being between the wick and the journal cotton-waste or other like fibrous material.

In front of the box, and communicating with the chamber p, is another opening, d, to which is adapted a screw-plug, e.

In ordinary boxes of this construction the openings through which the wick passes are directly beneath the axle, so that it is extremely dicult to gain access to the same. There is also no provision to prevent the oil from lowin g back from the axle into the chamber p, and the oil, as it thus flows back, carries with it particles of dust, which soon cause the oil in the chamber to become so thick and gummy that it will no longer flow up the wick.

It will be seen that in the box above described the openings t are situated in front of the axle, so that the wicks can be readily removed and replaced without lowering the box, while the flange t prevents the oil which has once been raised into the box fropi owing back into the chamber.

Oil may be introduced into the chamber p by different channels; but I prefer the opening n, forming a continuation ot' the hole for receiving the bolt m, as the most appropriate and only channel through which oil should be introduced into thesaid chamber, inasmuch as the packing oi the lid H forms a perfectlytight joint and prevents the escape of oil through the passage u.

After the withdrawal of the screw-plug c the interior of the chamber p may be cleaned. The opening al, too, affords facilities for the proper disposal of the wick by a suitable in*` I claim as my invention and desire to se cure by Letters Patent-h 1. The combination of an axleibox having an oil-chamber al; the under side and an open- In testimony whereof I have signed my ing, t, when the said opening is arranged in name to this speeication in the presence of front ofthe axle and is surmounted by a ange, -two subscribing Witnesses.

t, as'zmd for the purpose described. JOHN J. LAHAYE.

2. The passage u, communicating with the Witnesses:

chamber 19, and so situated that its upper end CHARLES E. FOSTER,

can be closed by the lid H. l W. J. R. DELANY.
