Application filed name 2,

To all whom itmay concern:

Be it known that we, Gnonon R. Harms, STANLEY Arena, ALFRED R. BENCH, and Gsoaes L. Bmwsggl, citizens of the United States, residing, res ectively, 'the said Gnonsn R. Harms an STANLEY Arena at Hi h Bridge, in the county of Hunterdon an State of New Jersey; the said ALFRED.

R. BENCH at Easton, in the-j-county of 19 Northampton and State of Pennsylvania;

and the said Gnonsn L. Bmwnnn at Riegelsville, in the county of Bucks and State of Pennsylvania, have jointly invented a certain new and useful Integral Beater Roll, of 1% which the following is a specification.

It has already been proposed to construct beater rolls with integral knives formed of manganese steel on account of its shock and wear resistive properties. A beater roll of 39 this type is disclosed in Letters Patent, No. 1,362,219, granted December 14, 1920, to George L. Bidwell; and the integral construction is rapidly superseding beater rolls of the wood filled type.

We propose to'construct a heater roll in the form of a single casting of manganese steel which, except for the headers or end closures, shall be complete and ready for mounting on the usual shaft of a Hollander 3% en e.

anganese steel odors serious foundry and heat treatment roblems and these have been carefully considered and overcome in the experiments leading up to our invent1on. The solid or integral construction to be hereinafter more particularly described, msures uniform heat treatment and hence longer life of the beater roll; it eliminates joints and their complemental fastenings -0 and the necessity of filling the joints to exclude 'ulp and water from the interior of the re in a word, it makes for economy as well in the manufacture and mounting of the roll as in the operation thereof.

One embodiment of our invention is illustrated in the accompanying -drawing, forming a part hereof, wherein- Figure 1 is a lo itudinal sectional view of a solid or integra y cast beater roll.

Fig. 2 is a cross sectional view of the same; and

Fig. 3 is a detail perspective view.

1922. Serial No. ceases.

According to our invention a heater roll exclusive of end plates, but inclusive of the knife carrying cylinder or roll, the spiders and the hubs or shaft receiving elements, is formed of a single casting, preferably of manganese steel. I

The knife carrying cylinder 5 is formed with a pair of spiders 6 terminating in sleeve-like extensions constituting hub elements 7 for the reception of the usual shaft. Each of the hub elements is nipped with one or more key-seats 8 where y it may be locked to the shaft, and diametrically opposite the seat or seats with counterbalance provision 9.

The spiders 6 have points of contact as by spaced integers 10 between the hub elements. The integers 1O constitute strengthenin provisions and also facilitate the flow 0 metal in casting.

The cylinder 5 is reinforced by radial ribs 11 and by longitudinal ribs 12. The cylinder and the spiders are additionally remforced by radially dis osed webs 13. The latter also constitute a utments /for the end closures 14, which may or may nothave-the usual bangers 15. The end closures Mare substantia 1y ground seated as at 16 and are retained by bolts or other suitable fastenlugs 17 on aging the spiders. This arrangement toget or with the absence of joints in the cylinder makes for a fluid tight roll.

Having described our invention, we claim 1. A beater roll embodying a hollow cylinder with integral knives and with integral radial supports formed with shaft 0 enings.

2. A beater roll embodying a hol ow cylinder with inte ral knives, means forcentering the cylin er, and ground seated end closures forthe cylinder.

3. A beater roll embodying a hollow inder with integral knives, means centering it including a spider at each end of the cylinder and formed'integral there with, and stress distributing provisions symmetrically formed over that area of the cylinder intermediate the spiders. g

4. A beater roll consisting of -a heattreated manganese steel casting formed as an open construction which is inclusive of an intact knife-carrying periphery and spaced radial supports formed with shaft openings.

5. A beater roll embodyin a hollow cylindrical casting with integra knives, means for centering it, and end closures for the cylinder.

6. A beater roll embodying a hollow cylinder with integral knives and with integral radial supports having shaft openings, and web connections intermediate said supports and the cylinder.

7. A beater roll embodying. a hollow cylinder with integral knives and with integral radial supports or centers, and ribs ranging longitudinally and radially of the cylinder and having points of intersection.

8. A beater roll embodying a hollow cylinder with integral knives and with integral centers joined by the bars, and means for bracing that portion of the cylinder intermediate the centers.

9. A beater roll embodying a hollow cylinder with integral knives and with integral radial supports or centers, and webs between newness the supports and cylinder and constituting abutments for end closures.

10. A beater roll embodying a hollow cylinder with integral knives and with an integral spider at each end thereof, the hubs of the spiders being integrally united at spaced intervals. l

11. A beater roll embodying an open cylinder with integral knives and with integral centers, and means for sealing the ends of the cvlinder.

12. A beater roll embodying a knife carrying cylinder of hollow construction formed with integral centers and with spaced integers connecting the centers.

13. A beater roll embodying knives, knifesupporting body, spiders, and hubs, all of said elements being cast integral.

In testimony whereof, we afiix our signatures. GEORGE R. HANKS. STANLEY APGAR. ALFRED R. BENCH. GEO. L. EBIDWELL.
