W. BORTON FRAME FOR CRUSHING MACHINERY Filed May 8, 1924 N U T U B E E Du D Patented Jan. 14, 1930 UNITED STATES PATENT OFFICE GEORGE BOR'I'ON, OF NEW LISBON, NEW JERSEY, ASSIGNOR TO PENNSYLVANIA ORUSHEB' COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK I FRAME FOR CRUSHING MACHINERY Application filed May 8,1924. Serial No. 711,786.

incident to the use of structures such as singleroll crushers.

And a further object of my invention is to utilize sections of heavy commercial roll ed metal members of I-beam section for the sides of such frame whereby I am enabled to take full advantage of the inherent stiffness and rigidity presented by the integral web and flan es of such members or sections.

y improved crusher frame is of the builtup type, that is to say, it is made of structural metal in substantially rectangular form, and its side Walls comprise a pair of I-beani members, which are connected together and spaced apart by suitable sections or members of rolled metal. The lower part of the web and 'the base flanges of said I-beam sections are continuous throughout their length, 'while portions of the top flanges and a portion of the upper part of the central webs are cut out midway the ends of such I-beams for the,

insertion of the crusher roll shaft bearings; the cut-out portions being filled in with matching parts, detachably secured in place, to complete the side walls of the frame.

These and other features of my invention are more fully described hereinafter; reference being had to the accompanying drawings, in which:

Figure 1, is a perspective view of a crusher frame having side walls of I-beam section, within the scope of my invention. 1

'Fig. 2, is a side elevation on a smaller scale,

of my improved structure, and g Fig. 3, is a cross sectional view on'the line III-III, Fig. 2.

' In the drawings, 1, 1, represent the sides of the crusher frame, made of structural shapes, preferably I-beam sections, each side having a web 2, with upper integral flan es 3 and 3*, and lower integral flanges 4 an 4. These sides are connected together, top and bottom, at their respective ends by cross members or plates, those at one end of the frame for inthe flanges 3 and the top portion of the sides, and a bottom plate 6 connected to the lower flanges 4 and 4 by rivets 6, and spacing the lower portion of the sides. The plate 5 is provided with an inclined ortion 5 which fits between the webs 2 o the I-beams, below the top of the same; such inclined portion 5 of the plate 5 servin to direct the material to the crushing roll, (indicated by broken lines), and the upper flanges 3 of the I-beams being cut away, as clearly illustrated in the drawings, to permit this arrangement and to accommodate the crushing roll.

At the opposite end of the frame, the I- beam sides are connected together by a top plate 7, which may be secured to the flanges 3, by rivets 7 and a bottom plate 8, which may be secured to the flanges 4, by rivets 8 In addition,

at the ends of the same externally of said sides, by means of rivets 10 and cross-braces 11, 12 and 13, extend across the end of the angle sections 10, vertically ,disvposed, are secured to the webs 2 of the I-beams stance comprising a top plate 5, secured to I 3, by rivets 5, and spacing frame between these vertical angle members 10; such cross-braces being secured to said members 10 by rivets or other suitable means. The cross-brace l1, underlying the plate 7, may be an angle member secured by rivets 11, to said top plate and to the vertical members 10; the cross-brace 13 may be in the form of a channel member secured by' rivets 13 or otherwise fastened to the bottom cross plate 8 and to the vertical angle members 10, and the cross-brace 12, which is in the form of an angle'member, may be secured to the vertical members 10-and also to the top flange of the channel member 13, by rivets 12, or other suitable fastening means.

The top flange 3 of each I-beam section forming thesides of the frame is cut away midway its ends, as indicated at 15, for re- 5 and the crushing roll; the position of which h latter element is lndicated in the drawing by broken lines, and in addition, the webs of the I-beam sides are notched or cut away at 16, for the reception of journal-boxes 20, receivin bearings21, for the shaft of the crushing r0 1. The gaps in the webs of the I-beam side plates receive filler plates 22, whose lower edge is preferably curved to fit over the ]O11I- nal-boxes, and superposed u on these plates are flanged sections 23, whic 'may beofpast metal, to fill out the gaps in the I-beam sides, with flanges 23 flush with the upper surface of and continuous with the flanges 3 of the I- beam sections 1.

A cross-brace 24 of I-beam construction is disposed between the sides 1, 1, of the frame; the top and bottom flanges of the cross-brace being cut away at the ends of. the same so :that the ed e of the web of such beam may fit against t e web of the beams formin the sides, and thetop and bottom flanges o the same. This cross-brace may be secured by bolts, rivets or the like, passing through the upper and lower flanges of the same and through the top and bottom plates 5 and B; the upper rivets being indicated at 5. Angle members 24 are secured at the ends of the cross-brace where they abut the side frames; such angle members being also secured to said side frames by rivets, bolts or other suitable fastening means.

In addition to the journal-boxes to receive theshaft of the crushing roll, the ends of the I-beam sides opposite t e cross-braces 11, 12 and 13, are provided with boxes 25, which ma be secured to the webs 2 by rivets 25; suc boxes receiving the bearings for the driving shaft, indicated by dotted lines. The webs of the I-beams are also apertured at 28, for the passage of the shaft or spindle upon which the concave or breaker plate of unitary or sectional construction (not shown), is hung.

By my improved construction I take advantage of the massive character of the I -beam members and the strength and rigidity of the same provided by the integral web and flanges which afford the necessary support for the cross-braces and other elements which make up the complete structure and maintain the parts in spaced relation.

As may be understood, the necessary rivet holes can be punched in proper sition by the use of templates and the who e structure fabricated in a cheaper and simpler manner than structures of the type in which side plates of cast metal are employed, with the added advanta e that no part of the structure subject to reaking stress or strain isof cast metal.

I claim:

1. A frame for-single roll erushers of massive construction, comprising side walls of standard rolled metal-I-beams; said walls being notched intermediate their ends by cutting through the u per flanges and web of said I-beams for t e reception of journalboxes; filler members closing the gaps in said walls and having ortions conforming exactly to the Web 1111C? flange of said side walls, and meansfor securing said parts together including cross members'of standard rolled sections.
