JACOB KRITOH, OF CLEVELAND, OHIO.
ole FOR' FORGING AXLES.
SPECIFICATION forming part of Letters Patent No. 337,504, dated March 9, 1886.
Application filed December 14. 1885. Serial No. 185,592. (No model.)
To all whom it may concern:
Be it known that I, J AOOB KRITCH, of Cleveland, in the county of Ouyahoga, and State of Ohio, have invented certain new and Improved Dies for Forging Axles; and I do hereby declare that the following is a full, clear, and complete description thereof.
The above-mentioned improvement in dies for forging axles has reference to a cutter secured transversely in the face of the upper section of the die, whereby the spindle ends of the axles, while being drawn and rounded by the die, are cut smoothly and evenly off, and all of an exact equal length, as hereinaftor fully described, and illustrated in the accompanying drawings, in which- Figure 1 represents a side View of the upper and lower sections of a rounding-die. Fig. 2 is a view of the face of the upper section of the die. Fig. 3 is a view of the face of the lower section of the die. Fig. 4is an end view of the two-part rounding-die. Figs. 5 and 6 are portions of an axle to which attention will be called.
Like letters of reference refer to like parts in the several views.
In the manufacture of carriage-axles the collar is formed on the blank or bar for axle before the blank is subjected to the rounding-die for having the spindle end drawn out and rounded into proper shape for the wheel. Ordinarily said rounding-die consists of two sections, an upper and lower one, and one the duplicate of the other in form. The axles on leaving the die are more or less variable in length from the collar out, whereas all of them must be of equal length, and that. they may be their ends are cut off by a pair of gaged shears, which tends to strain theiron and injure the axle. If the axles are of small size, the ends are cut ofl when cold, whereas axles of large size are reheated for that purpose. The ends of the axles, when cut either while hot or cold, are left rough and ragged, more or less, as seen at A in Fig. 5, rendering the end troublesome to center, that the axle may be placed in a lathe for further treatment in finishing.
To avoid inutilating the spindle of the axle in cutting or trimming it off is the subjectmatter of this invention, and which is effected by providing the upper section, B, of the die with a blade or cutter, O, arranged in a groove, D, transversely in the face of the die, and secured therein by the wedging-keys a and b,
substantially as shown in Figs. 1 and 2, or otherwise fastened in place. in said figures that the bevel of the cutter faces the groove in which it is keyed, thereby placing the plain straight surface of the cutter toward the form or concave c of the up It will be noticed per section of the die, which is nearly asemicircle, so that the edge of the cutter will be at the axial line of the die, as seen in Figs. 1 and 4, or of the axle when therein. It will also be noticed that the form or groove d in the lower section of the die is less deep than that in the upper section, B. The length of said form or groove from the end a to theedge of the cutter is the exact length required for the spindle of the axlethatis to say, for axles of a certain size and length.
The die above described may be operated either by a trip or drop power and as follows: The rough spindle end of an axle-blank, having formed thereon a collar, is heated and then inserted in the die, by means of which the crude end is worked down, rounded, and tapered by the action of the die, which at the same time becomes elongated by the excess of metal. The extending end as it continues to come under the cutter during the operation of the die is repeatedly cut into thereby and down to its axial line, and as the axle, by the workman, is constantly turned around while in the die the cutting is made repeatedly around in all sides of the axle and half way through it,instead of entirely through it from one side only, as done in the usual way above mentioned, by which the whole excess of the length of the spindle is cut off at once, whereas the cutter used in connection with the die cuts only so much off at one time as the spindle may continue to elongate while being operated on, and until the collar on the axle comes to the end a of the die, when the cutting ceases, as the collar acts as a gage for the length of the spindle of the axle, which leaves the die with the end smoothly trimmed and round, as shown at Gin Fig. 6, requiring no further treatment to prepare it for being centered for the lathe, instead of being left as shown at Ain Fig. 5, when out in the ordinary way. as above stated, which is additional labor and undue strain upon the iron.
WVhat I claim as my invention, and desire to secure by Letters Patent, is-
In a two-part die for rounding and shaping the spindle ends of axles, the upper reciprocating hammer-die having a detachable cutter, which cutter does not extend beyond the plane face of the die, in combination with the 10 lower die, substantially as and for the purposedescribed.
In testimony whereof I aflix my signature in presence of two witnesses J AGOB KRITGH. Witnesses:
W. H. BURRIDGE, J. H. BURRIDGE.
