MEANS FOR MAKING WHEEL-RIMS.
SPECIFICATION forming part of Letters Patent No. 602,926, dated April 26, 1898.
Application filed February 4, 1897. $erial No. 622,015. (No model.)
To ail whom it may concern:
Be it known that I, JULIUS ZiiHLKE, a subject of theGerman Emperor, residing at Neuwied, Germany, have invented certain new and useful Improved Means for Making Wheel-Rims, of which the following is a de- Scription.
This invention relates to improved means for producing a wheel-rim composed of a continuous grooved seamless annulus.
In carrying my invention into effect I form by pressure a hollow work-piece which corresponds in diameter to the diameter of the rim to be formed. This work-piece is grooved to assume the desired contour and is then cut up into narrow annular strips that constitute the rims.
In the accompanying drawings, Figure l is a sectional elevation of the machine for producing the rim; Fig. 2, a sectional plan thereof; Fig. 3, a cross-section on line B B, Fig. 1; Fig. 4, a similar section of the apparatus when arranged to make double rims; Fig. 5, a detail of disk (Z; Fig. 6, an end view of a single rim made by the machine; Fig. 7, a longitudinal section through a double rim, and Fig. 8 a transverse section through the double rim.
The letter 0 represents a hollow or cupshaped body adapted to be slipped over the grooved cylindrical former or roller a of a lathe, the parallel grooves of the former corresponding to the profile of the rim to be formed.
The former a is secured to the live-spindle b, driven by step-pulleys or in other suitable manner. A sectional disk d, slipped into work-piece c and placed against its bottom 0, serves to reinforce the work-piece and constitutes at the same time an abutment for the free end of the former, which bears directly against such disk. After the work-piece has been placed over the free end of the former a head cl, fitted to a sliding or extensible.
to spindle b to produce while revolving a contact along one line between the former and the inner face of the work-piece, Fig. 2. Opposite to this line of contact there is secured to the machine-frame A, by means of a slide 6, a spinning-roll 6, adapted to engage the work-piece and to spin or force it inward between the ribs of the former a. The slide e is laterally movable upon its rest 6 by means of a screw 6 or otherwise, so that roll 6 may be brought into alinement consecutively with the different grooves of the former. The slide is of course also longitudinally movable, so as to permit the spinning-roll to be advanced toward or withdrawn from the work. The roll can be of such size and configuration that a number or all of the profiles are shaped at one and the same time. After the work has been spun as described it is cut up into grooved annuli, Fig. 6, which are formed by cutting through the center of each of the beads spun upon the work-piece. In this way each annulus is of the proper configuration to constitute a continuous grooved seamless wheel-rim.
If double rims are to be formed, a single hollow work-piece or cylinder f is first shaped with deep grooves f. Around this is slipped a second hollow work-piece or cylinder g, and into this second work-piece shallow grooves g are spun. The cylinders are then out up into annuli and the edges of every rim thus formed are intimately connected by a lapjoint, Fig. 8.
If desired, the hollow work-piece may be first cut up into rings and may then be spun. The bottom 0 may be utilized for difi'erent purposes.
1. The process of forming a compound wheel-rim which consists in forming a cylinder with deep grooves, surrounding it by a second cylinder, forming the same with shallow grooves, subdividing the telescoped cylinders into rings, and uniting the edges of the rings, substantially as specified.
2. In a machine for forming wheel'rims the combination of a spinning-roll with a cylindrical former having a series of parallel grooves, and with a sectional disk 65, adapted to reinforce the bottom of the work-piece and to constitute an abutment for the free end of the former, substantially as specified.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
