Application filed December 4, 1899. Serial No. 789,167. (No model.)
Manufacture of Axle-Boxes, of whichthe following is a specification.
. Heretofore the main body of an axle-box has in various Ways been made'of Wrought metal. Either it has been made from one piece of metal which has been first rolled intoa plate and then bent and welded up into the I form required or it has been made in separate parts which have been secured to one another by serew-b olts. According to my invention I form the main bodyof an axle-box,
including the top, with the spring-seat upon' it, the front and rear ends and the'two sides,
with the axle-guard grooves extending down them, all in one piece of wrought'metal without joint, whereby I am enabled to manufacture axle-boxes both stronger and lighter than those heretofore made, while at the same s time they canbe made at less cost.
To accomplish the manufacture of axleboxes in the above way, I proceed as follows and as is illustrated in the drawings annexed.
Figure 1 is a perspective view of the block of wrought metal from which the body of an axle-box is to be formed. Figs. 2 and 3 are perspective views'of such block after a hollow has been molded on its under side and a spring-seat on the top. Figs. 4 and 5 aresections of the die through which such molded block is subsequently forced. Fig. 6 is a perspective view of the body of the box when finished. Fig. 7 is a perspective View of the tray for closing the bottom of'the box. Fig. 8 is a perspective view of the axle-box complete.
Itake a block of wrought metal, preferably steel, of the required amount to form the body of the box, and I form with dies, preferably by hydraulic pressure on two opposite sides, the first shaping of the axle-guard grooves, (marked a, Fig. 1.) I then squeeze the block between another set of dies, preferably by a hydraulic press, and form the spring-seat (marked 1)) on the top and the indentation the body of the box, as shown in Fig. 6.
(marked 0) on the under side, as shown in Figs. 2 and 3. The block so shaped is next brought to a proper heat and the top end (marked 01 in Fig. 4) is chilled to enable it to retain its-shape. The block is now placed onto the end of a ram 6 and forced through the die, (marked f,) the arrangement of which is fully seen in Figs. 4 and 5. As the heated metal passes through the die it is drawn down on all four sides, the final shapingof the grooves being aided by the rolls g, The last portion of the die gives the final formation of Afterward an oval hole is cut through the back for the end of the axle to pass into the box, and another hole is formed through the front toserve as an inspection-hole and for intro ducing oil. This hole is closed by a door It, as shown in Fig. 8, which is a perspective View ofthe finished box. The bottom of the box is closed bya tray, (marked 'iand shown separately at Fig. 7.) It is preferably made of wrought steel and carries an upwardlyprojecting guard-plate 70 at its back end to hold the ordinary dust-shield between itself and the inner face of the back of the box. The tray serves to contain the oil used for lubrication and also carries the lubricatingpad, by which the oil is applied to the under side of the axle in the usual manner.
Having now particularly described and as= certained the nature of my said inventionand in what manner the same is to be performed, I declare that what I claim is- The hereinbefore-described process of formin g an axle-box body consisting in first molding projections for the axle-guard grooves on two opposite sides of a rectangular block of wrought metal, next squeezing such block when heated between dies to form a hollow in the bottom of the block and a spring-seat on the top, then heating such block and chilling the spring-seat 'after it has been heated and finallyforcing the block through a die by which it is drawn down on all four sides and brought to the required shape.
