General Description.
A. represents the axle in its various forms, and a the internal longitudinal ribs formed therein, which are likewise shown in the flat metal plates represented in Figs. 4. and 5. R It are a pair of rolls adapted to form the ribbed plates or bar shown in Fig.5. The upper roll R is formed with a number of eircumierential grooves, 1", which produce the ribs a. The lower roll R has a large groove with a plain bottom to form the smooth exterior face of the bar, and at proper points within this groove are projections r, which produce depressions at proper points for the journal-surfaces. S is a cutter to sever the bar into the requisite lengths. Referring to Figs. 9 and 10, B represents the matrix or female die for forming the ribbed plates into segments or axle-sections. follower-die, which is formed with ribs 0, adapted to project between the ribs a of the plates. D is a key for securing the sections 0 O O of the follower-die together. E is a pivot, on which the outer sections 0 O are adapted to swing. F F represent toggle-levers for forcing up the matrix-die B. These may be operated by a connecting-rod, G, attached ism, by which action the plate is bent into the segmental form represented, the ribs B projecting into the grooves which are formed between the ribs a. In order to separate the parts of the die it is now necessary toremove the key D, when the central member 0 of the follower-die may be taken out and the outer members 0 will fall together by their gravity, or may be readily detached by a slight blow. The segment-plate is now finished in readiness for the welding process.
In the illustration here given the segmentplate will be seen to form an arc of one hundred and eighty degrees, so that it will constitute one-half of the hollow shaft. Two such segment-plates being now adjusted, with their edges together and suitably wired,.are placed in the furnace, and when heated to the welding temperature they are partially withdrawn therefrom; but while remaining within the atmosphere or flame or heat of the furnace they are introduced between suitable dies andinstantaneously pressed together in the manner 0 O 0 represent the three parts of the a described in a separate application which I To the above specification of my improvehave made for Letters Patent. ments in process and apparatus for constructing axles I have set my hand this 5th day of July, 1871. I claim as my invention WM. ARNOLD LEWIS.
