i v IMPROVEMENT IN .AXLEl-BOX.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.'

Be it known that I, DAVlD DALZELL, of South Egremont, in the county of Berkshire and State of' Massachusetts, have invented a new and improved A xle-Box, for the hubs of wheels for carriages, wagons, 85e., and which I term a Gom pound Axle-Box and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying` drawing and to the lettersiot' ret'- erence marked thereon making part of this specitication, in which- Figure 1 is a side view of my invention.

Figure 2, a longitudinal central section of the same.

Figure 3, an end view ofthe same.

Similar letters of reference indicate corresponding partsin the several gures.

lhe object of this invention is to obtain all the advanta ges derived from an entire wrought-iron and casehardened axle-box at a cost far below that attending the original mode of manufacture.

This result is accomplished by dispensing entirely with forging, which I am enabled to do by-having the box com posed of two parts, one part, that which runs or turns on the arm ot' the axle, and is the only portion subjected to wear, being of wrought iron, casehardened, and the other part, which is subjected tono wear, and which has hitherto been attended with great trouble and expense in forging, beingr of cast-iron, lnalleableized.

These two parts are connected by a screw-joint, as hereinafter set fort-h.

To enable those skilled in the art to fu'lly under- V stand and construct my invention I will proceed to deleast expensive, but do not confine myself to it, re serving the right to use wronght-iron in any form.

The exterior of this part A is turned of slightly taperform, and the interior is reamed out as true as may be, and made to conform to the shape of the arm of the' axle, on which it is designed to turn, said part A be ing case-hardened, to obtain the requisite degree or hardness to resist weau The inner part of A is turned down a suitable distance of its length, to form a shoulder, a, and a screwthread, l), is cut on the exterior of the turned-down portion, to admit of the outer part' of the other portion, designated by B, being screwedl` upon it, (see g. 2.) i

I he portion B is of cast-iron, malleableized, and is cast with ears c c, to prevent the box from turning within the hub, and in order to prevent the two parts being casually nnscrewed from each other, a key or pin may be inserted in a seat or in a hole drilled in the adjoining ends ot' said parts. I do not think, how- -What Irclaim as new, and desire to secure by Lctters Patent, is-

An axle-box for the hubs of carriage and wagonwheels, constructed of two parts, A B, one of' which is ot' wrought and the other of cast metal, the two parts being connected together substantially as and for the purpose specified.
