CALENDER-ROLL.

SPECIFICATION forming part of Letters Patent No. 511,606, dated December 26, 1893. Application filed April 25, 189]- Serial No. 390.486. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, HERBERTJ. FRINK, of Holyoke, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Oalender- Rolls, of which the following is a specification, reference being bad to the accompanying drawings, forming part thereof.

This invention has for its object the construction of a roll for calendering paper and other fabrics, and relates particularly to that class of rolls composed of a metallic arbor and a homogeneous outer covering or cylinder of fibrous material.

In accordance therewith my invention consists in a calender roll, consisting of an arbor, a series of separated rings embracing said arbor at intervals between its ends and having a spline and groove connection therewith, the parallel surfaces of said rings havmg irregularprojections thereon, a homogeneous outer covering of fibrous material surrounding said arbor from end to end Wholly inclosing said rings and extending inward between them, and two heads secured upon said arbor at each end of and to compress said outer covering, said heads each having in their inner sides a depression corresponding 1n diameter substantially with that of said rings, substantially as will be described.

Other features of my invention will be hereinafter described and particularly pointed out in the claim.

Referring to the drawings, in which like letters designate like parts in the several figures, Figure l is a longitudinal sectional view of a calender roll embodying my invention, the arbor being shown in elevation. Fig. 2 is a similar view thereof taken in a plane perpendicular to thatshown in Fig. 1. Fig. 3 is a plan View of a locking ring to be described. Fig. at is a cross section thereof on the line araa, Fig. 3. Fig. 5 is a cross section taken on the line yy, Fig. 3, and Figs. 6, 7 and S are plan and sectional views of a modified form of'ring to be referred to.

Referring to Figs. 1 and 2, I have herein shown the roll as composed of a metallic arbor a surrounded by a homogeneous outer covering or cylinder b of compressed cotton or other suitable fibrous material, metallic heads C, C, being secured to the arbor at each end of the outercovering. In the manufacture of such rolls the fibrous outer covering is subjected to great pressure, in a direction parallel with the axis of the arbor, and in order to secure the heads 0 upon the arbor in such manner as to withstand the expansive action of said c0veriug,l have herein shown at each end of the arbor, beyond the outer covering, a frusto-conical hub a upon which are placed similarly shaped rings 0 to enter the conical bore of the heads (J, as clearly shown in Figs. 1 and 2, the outer ends of said rings 0 being engaged by collarsC shrunk upon the arbor and thereby securely held in place. So far as this invention is concerned, however, any

other usual means employed for holding the device upon the arbor can be utilized. The end pressure exerted by the heads upon the outer covering 1) is not sufficient to prevent it from turning bodily upon the arbor or having a twisting movement thereon unless other means are provided, particularly in the case of the rolls in calendering machines where they are subjected to great strain in performing their function, the covering tending to turn or twist upon the arbor, and when this occurs the roll is rendered useless. I have herein shown convenient means for so looking the said covering to the arbor that turning or twist-ing thereof on the arbor is rendered absolutelyimpossible. In order to accomplish this result I place a series of separated rings or disks d upon the arbor at intervals between the heads 0, and the said rings are securely locked both to the arbor and to the covering, which latter wholly incloses said rings and extends inward between them, as clearly shown in Figs. 1 and 2.

Referring to Figs. 3, 4 and 5, the ring (Z is shown as composed of a flat piece of metal stamped or otherwise formed into annular shape, the central opening therein being of such a diameter as to cause it to closely fit upon the arbor a. The periphery of the ring is preferably beveled to an edge, as shown in Figs. 1 to 4 and 6, and one or both of its parallel surfaces are pricked or burred to form irregular projections thereon which engage the fibrous material of the outer covering b when the latter is compressed upon the ring,

ICO

thus locking the outer covering and the rings securely together. To prevent rotation of the ring upon the arbor 2, inwardly projecting lugs b are secured to or form a part of the ring at opposite sides of the central opening, and said lugs are adapted to be received within longitudinal grooves 0, in the arbor.

In the modification shown in Figs. 6, 7 and 8, the locking ring has a serrated periphery to cause it to take a firm hold of the fibrous outer covering, and it is provided with notches or recesses d to receive a spline formed upon or secured to the arbor to lock it thereon.

In practice I prefer to utilize a series of locking rings (1 located at intervals of several inches upon the arbor, as shown in Figs. 1 and 2, the outer diameter of said rings being substantially two-thirdsthat of the outer covering b, as shown. The rings are applied successively to the arbor between layers or cheeses of the fibrous material as the lat ter is built up upon the arbor, and the press- A roll constructed in accordance withmy invention as herein described is not materially increased in cost, and'it is impossible to turn or twist the outer covering thereof upon the arbor under any circumstances, so that the capability and durability of the roll are materially increased.

I claim The herein described calender roll, consisting of an arbor, a series of separated rings embracing said arbor at intervals between its ends and having a spline and groove connection therewith, the parallel surfaces of said rings having irregular projections thereon, a homogeneous outer covering of fibrous material surrounding said arbor from end to end Wholly inclosing said rings and extending inward between them, and two heads secured upon said arbor at each end of and to compress said outer covering, said heads each having in their inner sides a depression corresponding in diameter substantially with that of said rings, substantially as and for the purposes described.

HERBERT J. FRINK.
