RAG-BEATE R.

SPECIFICATION forming part of Letters Patent. No. 256,352, dated April I1, 1882. A Y' Application med Maron 9, 1882. (No model.)

To all whom t may concern:

'Be it known that I, GUYON MILLER, of Downingtown, in the county f Chester and 'State of Pennsylvania,'have invented certain new and useful Improvements in Rag-Beaters; and I d'0 hereby declare that the following is a full, clear, and exact description thereof, referencebeinghad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in Whiohl Figure l is an end view of my roll or beater.

Fig. 2 is a diametrical section through the same.

This invention relates to an improvement on rag-engines,'pulp, and all kinds of paper-stock dressers; and the nature of myinvention consists in the novel construction of a rollor beater by combining steel, iron, and wood in such manner as to secure great strength and durability, and to .secure the wood filling so that it will not fly out when the roll is rapidly rotated, as will be hereinafter explained. The following description of my invention, when takenin connection with the annexed drawings, will enable others skilled in the art to understand it.

A designates thespindlev on which the improved roll is keyed, and B B are cast-iron heads arranged at suitable distances apart on the spindle.

C designates the wood base filling, constructed with tenons a, which are fitted tightly into mortises or annular grooves b in said castiron heads and rigidly confined therein by means of Wrought-iron clamping-bolts D.

(Shown in Fig. 2.) The filling U is thus prevented from becoming loose or being thrown out by the centrifugal force of the roll when rapidi y rotated. v

E E designate the steel blades or iiy-bars, provided with notches or slots-F for the reception of Wrought rings or bands c, by which said bars are secured in their places at regular intervals apart, and J J indicate slots in the cast heads B for the reception of the fly-bars.

Between the fly-bars E, and rigidly secured to the base filling C by means of nails, are layers of wood iillin g for affordin g braces or stays to these fly-bars.

Instead of the mortises or grooves in the I cast heads to receive tenons formed on, the filling C, I shall sometimes cast the heads B with tenons or projections and form the mortises, grooves,or indentures in the ends of the Wood filling. This modification Iconsider the equivalent of the plan Iirst described for fastening the base filling permanently to the heads.

Having described my invention, I claim- A rag beater or roll consisting of iron heads cast with mortises oroth'er depressions for the reception of the wood filling (l, the wood filling constructed with tenons adapted to t into said mortises, and the bolts for clamping the whole firmly together, substantiallyin the manner and for the purposes described.

In testimony that I claim the foregoing as my ovvn I affix my signature in presence of two witnesses.

` GUYON MILLER.
