ANTON BRAUN, OF JERSEY CITY, NEW JERSEY.

VEHICLE-AXLE AND Box.

SPECIFICATION forming part of Letters Patent No. 364,333, dated June '7, 1887.

Application filed December 8, 1856. Serial No. 252L028: (No model.)

To all whom it may concern:

Be it known that I, ANTON BRAUN, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Vehicle-Axles and Axle- Boxes, of which the following is a specification.

My invention relates to those axles in which the wheel is retained upon the axle by the engagement of the axle-box with the axle near its inner end, as distinguished from those axles in which the wheel is held in place by a nut applied at the extremity of the axle-arm.

The invention consists in novel details in the construction of the parts which embody my invention, and in the combinations of such parts, which are particularly hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an axial section of a wheeLhub and axle-box and a side view of an axle-arm embodying my invention, and Fig. 2 is a transverse section of the axle and an end view of the inner end of the hub.

Similar letters of reference designate corresponding parts in both figures;

A designates the axle or axle'arm, of which I have here represented but little more than the journal portion, and B designates an axlebox, which is secured in the ordinary or any other suitable way in the hub O, and which is fitted to the journal of the axle A.

In this example of my invention the axle arm or journal is somewhat tapered toward its outer end, and the axle-box is bored to a corresponding taper. Immediately at the inner end of the taper journal portion of the axle is a fixed or integral collar, 1), and at this end the axle-box is closed bya cap, B, which may be secured in place at the inner end of the axle-box by screws 1). Any number of screws may be employed, four only being here shown. 1

Immediately inward of the fixed collarb the axle A has a short cylindrie portion, A, and the cap B is bored to fit this cylindric portion, and inward of such cylindric portion A the axle A may be of ordinary square or rootangular form.

In the inner end of the axle-box B is formed a rabbet or chambered space, Z1 which is of sufficient diameter to receive the integral collar b of the axle A, and upon the outer side of this collar, and between it and the bottom of the rabbet or chamber N, is a packing-washer, c, which maybe of leather or other suitable packing material,aud which is of substantially the same diameter as the collar. The inner face of the collar 1) is substantially flush with the inner end of the box, and the inner end of the .box is substantially flush with the inner to end of the hub G, and upon the inner side of the fixed collar 1) is a second packing-washer,

c, which may be of leather, or, if desired, of metal, and which is interposed between the cap B and the collar b, and is clamped and 55 held in place between the cap B and the inner end of the box, thereby forming an airtight joint. It will be observed that the ta per journal portion of the axle extends immediately from the collar 2) to its outer end, the journal having a continuous and uninterrupted taper between its outer end and the collar 0. The axle-box B, which is tapered internally to fit the journal portion, is constructed in the same manner, and the tapered bore of the axle- 7 5 box extends from its outer end clear to the bottom of the rabbet or chambered space b".

By means of the fixed collar b fitting within the chamber or rabbeted recess at the inner end of the axle-box B, the axlebox and wheel are securely held against any sliding movement on the axle, and the packing-washer c prevents leakage of oil from the axle-box, while the packing or washer 0, in addition to its function in preventing leakage, forms a part which may be readily renewed, and which takes the wear due to end-play of the axle in the box.

As here represented, the journal portion of the axle A extends entirely to its outer end and the axle-box B projects slightly beyond the outer end of the axle A, and is closed by a cap, B or analogous plug, in order to form a closed oil-chamber, D, at the outer end of the axle. The cap B may be provided with 5 a fillinghole closed by a plug, (Z, and whenever desired said plug may be taken out and a proper quantity of oil may be supplied to the chamber D.

In order to provide for the free lubrication of the axle-journal A from the closed oil-chamber D, I have represented the axle-box B as provided with grooves b in its bore. These grooves b are, as here shown, at diametricallyopposite points, and as they are brought successively to lowermost position by the turning of the wheel they convey oil to the bearing-surfaces of the axle-box and axle.

I am aware that axle boxes and j ournals have been made with taper bearing-surfaces,and that a closed oil-chamber has been provided in the box by a cap screwed upon its outer end, and that a wheel has been held in place on the axle by a collar on the axle, which is confined between the axle-box and a cap or plate secured to its inner end. I therefore do not claim, broadly, any of these features, but desire to restrict my invention to the particular combination of parts above described and shown in the drawings as a whole, whereby I produce an axle and axle-box possessing advantages which no axle or axle-box known to me has had.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The combination, with hub O, of the box B, extending the entire length of the hub, and having secured upon its outer end the cap B, forming a closed oil-chamber, D, the box having at the inner end the rabbet or chambered space 12 the axle A, having an integral collar, b, received in the rabbet b", and the outer face of which is substantially flush with the inner end of the box, and having a straight taper journal extending outward from the collar and fitting the tapered bore of the box, the washer c, of substantially the same diameter as said collar, fitted between it and the bottom of the rabbet b, the cap B, closing the inner end of the box around the axle and secured by screws 1) directly to the box, and the washer c, hearing against the inner face of the collar b, and held in fixed position between the cap and box by the screws 1), all substantially as herein described.

ANTON BRAUN.
