Application filed Januaryl, 1918. Serial No. 214,672.
which it appertains to make and use they same, reference being had to the accompanymg drawings, forming part of this specification.
My invention relates to a cage or screen for material reducing or pulverizing machines and particularly those machines utilizing hinged or pivoted hammers or beaters, and which latter are carried by a shaft which rotates at a relatively high speed.
The principal object of my invention is to provide a cage or screen which is comparatively strong, rigid and durable andthe parts of said cage or screen including the framework being made up of ordinary and readily obtainable structural shapes which canv be easily worked and assembled to produce the finished cage, thereby materially reducing the cost of manufacture.
A further object of my invention is to provide a cage or screen which requires no machining and very little, if any, smithwork in its manufacture.
It will be understood that cages or screens utilized in connection with reducing machines employing pivoted hammers or beaters a curved lengthwise or formed on the arc of a circle which is concentric with the shaft carrying the hammers or beaters, and it is one of the objects of my invention to construct an' arcuate cage or screen so that it will be effective in resisting strains and forces which it may be subjected to while in service and which may tend to distort or bend it to such a degree as to render-it unfit for service.
With the foregoing and other objects in view, my invention consists in certainnovel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevational view of a cage or screen of my improved construction.
Fig. 2 is a plan view of the side portion of my improved cage.
Fig. 3 is a perspective view of one'vof the corners of the cage.
the corners of thecage. Fig. 5 is a sectional view taken mately on the line l5``5 of Fig. 1;
Referring by numerals to the accompanyapproxi- Flg. 4 is a rear elevational view of one of ing drawings which illustrate'a practical embodiment of my invention, 10 designates a reticulated member, preferably aA metal plate or sheet having holes punched therein',
said plate being bentl into arcuate form. v
Positioned on the side edges of the reticulated plate 10 and against the inner faceV thereof are rails or bars 11, the outer portions of which extend beyond theedges of the plate l0, and formed integral with the outer face of each bar at the ends thereof and at suitable points intermediate said ends are outwardly projecting lugs 12, the same being equal in thickness to the thickness of plate 10. The bars 11 are secured to the reticulated plate by fastening devices.
Applied to the underside of the reticulated plate 10 are transversely disposed rails or bars14, the ends of which bear directly against the lugs 12 and these bars are firmly secured to the rails or bars 11 by means of rivets 15 or like fastening devices, the same passing through said rails or bars 11, the
The lugs 12 serve as spacing elements between the bars `11` and 14 and in addition, they serve to prevent any tendency of the means of rivets 13 or like n reticulated plate 10 to move laterally as a l.
A cage of my improved construction is comparatively` simple, can be easily and cheaply manufactured, inasmuch as they are made up of ordina-ry shapes and require no machining and very little smithwork, and said cages can be made in Various sizes and shapes to suit different requirements, and they are particularly designed to resist service shocks, strains and Wear.
It will be readily understood that minor changes in the size, form and construction of 4the Various parts oi' my improved cage may be made and substituted for those herein shown and described, Without departing from the spirit of my invention, the scope of Which is set forth in the appended claim.
I claim:
l In `a cage for reducing machine having rewolving beaters or hammers, the eomloina-. tion with a foraminous plate curved throughout its length, of a combined frame and support for said plate, said frame comprising cur-ved bars secured to the inner face oraniinous plate adjacent Ito the ledges thereof, andseparate fastening means seated in and passing through the curvedbars and the ends of the'transversely disposed bars.
In testimony Whereo2 I hereunto aliiX my vsignature this 26th day of January, .1918.
