UNDULATING ROLL Filed Aug. l2, 1944 Patented Aug. 15, 1950 UNDUL'ATING RoLL f Mansel E. Honk, Pittsburgh, Pa., assigner to "Carnegie-Illinois Steel YCorporatiom a corporation of New Jersey Application August 12, 1944,-serria1rNo. 549,235
countered in separating them. In electrolytic tinning, for example, a certain number of'the sheets are given an oil emulsion treatment and are not processed through the branner, which subjects the sheets to a slight deformation and prevents sticking. The sheets which have been given the oil' emulsion treatment are flat and pile very compactly. In order to prevent the sticking of these sheets, they are passed through two sets of rolls,E the ltop roll of one set and the bottom roll of the other set being a smooth roll. The other roll in each set is an undulating roll which is usually made with molded protuberances thereon. The vpassage of the sheets through these rolls place very slight irregularities or indentations therein,y which are so minutejthat they ,are only apparent on very close inspection of the sheets. However, this deformation is suflicient to prevent sticking of the sheets together. v
t 'Ihe molded roll requires special molding equipment and may be seriously damaged by cuts or abrasionsfrom cobbled sheets. When lthe protuberances become worn or broken, it is necessary to go to the expense of replacing the entire roll.
It is an object of this invention to provide an undulating roll having a working surface which consists of replaceable balls instead of molded rubber.
This and other objects will be more apparent after referring to the following specification and attached drawings in which:
Figure 1 is a longitudinal view, partially in cross section, of the roll;
Figure 2 is an end view thereof; and
Figure 3 is an enlarged view of a detail of the invention.
Referring more particularly to the drawings, the reference numeral 2 indicates a shaft having bearing surfaces 4 and 6 on its ends and with the usual drive connections. Between the bearings the shaft 2 is provided with a portion 8 of greater diameter than the bearings. A collar I is welded to the left ihand end of this portion of the shaft as seen in Figure 1. The right hand end of the shaft is provided with a tapered portion I2 for a purpose which will appear later. A collar I4 is fastened to the right hand end of the shaft by means of a tapered pin I6 which passes through the holes I8 in. the collar I4 and the hole 20 in the shaft 2. A sleeve 22 is sup- 6 Claims. (Cl. 80-58) ported on and spaced from the shaft 2 by means offthevcollars Ill and I4. The internal diameter of the sleeve 22 is increased at its ends to form shoulders 24 which abut against the collars I0 and I4 to prevent longitudinal movement of the sleeve 22. A plurality of holes 26 extends through the Walls of the sleeve 22, these holes being arranged in the manner shown in Figure 1. A retainer 28 having a frusto-spherical opening Y3Il therein is retained in each hole 26 by peening over the edges or by a press t and a hard rubber ball 32 is received in 'each opening with a portion thereof extending from each end of the opening. The inner portion of the ball bears against the shaft 2 while the outer portion forms the protu'- berances on the roll. When a ball becomes Worn, it may be removed and a new ball inserted in its place or the ball may be turned to a newpositio to renew the working surface. y
The roll is made as follows:
' A 'collar I!) is welded to the left end of the sur face 8 Vof the shaft as shown in Figure 1.4 A retainer 28, having a frusta-spherical opening 30, is pressed or otherwise fastened in the openings 26 in the sleeve 22 and a hard r-ubber'ball 32 Ais glued into each of the openings 30. The sleeve with the balls attached thereto is then slid over the right hand end of the shaft, the tapered portion I2 facilitating the sliding of the balls onto the shaft. After the left hand end of the sleeve 22 abuts and is supported by the collar I0, the collar I4 is slid over the right hand end of the shaft to support the right hand end of the sleeve. The pin I6 is driven into place to retain the collar I4 on the shaft, thus retaining the sleeve 22 in the position shown in Figure 1.
While one embodiment of the invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
I claim:

An undulating roll comprising a relatively smooth shaft, a collar on each end of said shaft, a sleeve supported on and spaced from said shaft by said collars, means for fastening said sleeve to said shaft for movement therewith so that the shaft cannot move with respect to said sleeve, said sleeve having a shoulder at each end against which the inner side surface of the collar adjacent thereto bears to prevent endwise movement of said sleeve, one of said collars being xedly connected to said shaft and the other of said collars being removably attached to said shaft, said sleeve having a plurality of holes extending the shaft cannot move with respect to said sleeve-21 said sleeve having a plurality of frusto-spherical openings extending throughv the wallsY thereof, and a compressible ball retained in each ofl said openings and bearing against said shaft, said ball extending outwardly from said sleeve,4 saidshaft,
