IMPROVEMENT IN AXLES FOR VEHICLES.

diesv that stamp them into half-sections of an.

axle, and then uniting saidsections, one directly above the other, by collars and through-bolts iu such manner that the sections will be held together, and at the same time prevented from turning and chan ging their relative positions, as hereinafter more fully described.

In the accompanying drawings, Figure l is a perspective view of my improved axle as applied to the connecting parts of a carriage or wagon; Fig. 2, a central longitudinal section through the axle, and Fig. 3, a plan view of one of the plates before it is placed between the dies to receive the proper shape.

Inthe construction of my improved axle, I take a rectangular sheet of iron or steel of proper thickness, and, by means of a templet, pattern, or gage of suitable form, shear oi' the corners to form tapering ends. The lengths of the sides of the blank thus formed correspond with the length of the arm or journal of the axle, and one of its tapering sides is inclined less than the other to give to the axle the suitable gather. The blanks are then heated and placed between dies in a drop-press that gives to them the proper shape to form half-sections A B of the axle, the tapering ends of the blanks and the form of the dies being such that when the half-sections are placed to gether the arm7 or journal of the axle will have the required set7 and gather.77 The various holes for through-bolts, rivets, and for lubricating are then drilled at suitable places in the sections, and they are clamped together, one above the other, to form a tubular axle having a cylindrical body and tapering arms. Short pieces of tubing C C are secured interiorly to the ends of the arms O by rivets c c, and project outwardly, the exterior of the pro jectingparts being provided with screw-threads for receiving nuts D that secure the wheel to the axle. iron, the inner diameters of which are slightly smaller than the cylindrical portion or body of the axle, are then shrunken on in the wellknown manner, and serve not only as a shoulder for the wheel, but also to clamp and strongly bind the two sections together. The ends of the hounds F rest in socket -plates placed at the top of the upper sectionA of the axle, and a head block or bolster, G, rests upon and is mortised to receive the ends of the hounds, and serves to bind them together. Brace-rods H secured to the fore part of the hounds are connected to the lower section B of the body of the axle. Through-bolts I Il I2 pass through the ends of the braces, axle-sections, sockets, hounds, and head-block, and securely bind and clamp them together in such manner that the section Awill be held securely at all times above the section B of the axlebody, by which means the parts are securely connected together, and the sections more effectually prevented from separating. The oilholes K K are placed at a convenient distance from the collars, and partitions or bulk-heads K K extend across the lower half of the axle between the oil-holes, and serve as dams to prevent the oil from passing through the axle from wheel to wheel and escaping through the bolt-holes. The dam forces the oil outwardly by means of the inclined plane, from whence it passes through an oilslot, la 7c, in the lower half ofthe axle, to the skein or hub of the wheel. rlhe axle-nut D can be removed to aiford access to the oilfount through the thimble when desired for cleansing the same. The arms may be case-hardened, and are then turned and trued off in a lathe in the well-known manner. The shape of the body of the axle may be changed or varied to suit the fancy of the manufacturer, and additional trimmings may be attached to the same without departing from the spirit of my invention.

By the abovedescribed mode of construction, I obviate the necessity of welding the sections together, which can be but imperfectly done, and is an expensive operation..

The superior qualities of the metallic tubular axle-affordm g strength, light-ness and dura- Oollars E, preferably of wrought? two sections clamped together, one above the other, by shrunken collars and through-bolts, substantially as described.

2. The hollow sectional axle, bound together by through-bolts, having partitions to form oilreservoirs at either end, and also to prevent the escape of the lubricating material through the bolt-holes, substantially as set forth;
