PATENT 'CRUSHER aruLvsarzna COMPANY, orsr. Lou-1s, MISSOURI, I

-A CORPORATION OF MISSOURI. I

T0 at whom it may concern;

Be it known that I, MILTON F. WILLIAMS, a' citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Cages for Crushers and Pulverizers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a sectional view through a crusher or pulverizer in which my improved cage is mounted. Figs. 2, 3, and 4 are detail sectional views showing the adjusted position of the cage-bars, and Fig. 5 is a fragmentary pers ective'view of the cage-bar terminals.

T 's invention relates to a new and useful improvement in cages for crushers and pul verizers.

One of the objects of the invention is to construct a cage so that the parts thereof will occupy a small space in shipping and also to provide ring-mounts of various sizes for the cage-bars, whereby the several sections may be removed and new ring-mounts of different sizes inserted, so as to adjust the cage-bars inwardly and take up the wear on the ends of the revolving beaters.

In the drawings ,1 designates the side frame of the machine, in which is mounted a rotatable shaft 2, having hammer or heater supports 3, pivotallycarrying beaters 4.

5 is the top or cover of the machine.

The material to be acted upon is fed into a ho per at'the forward end of'the machine and at-the lower end of which it is'acted upon by the revolving beaters, the material passing over a cage or screen, preferably composed of bars, until it is reduced to such size that its particles can pass through the openings therebetween.

The sides of the frame 1 are provided with curved grooves, from the bottom walls of which project lugs 1 for receiving the cagebars and ring-mounts of different sizes, and in order toremove the cage and adjust it or put in new bars it is only necessary to-raise the hinged cover and withdraw the cage from its circular grooved seat. It is part of my present invention to group the cage-bars, so

that the cage may be inserted or removed in cured together by means of'a rivet 7 passing throughthe heads thereof. The ring-mounts (designated by the reference-numeral 8 and seated in the curved seats) are preferably provided with arcuate grooves 9 for the reception of the bars 6. The curved seats in the side frame 1 are of such radial depths as to receive the groups of cage-bars and leave spaces above and below them, which spaces will be determined by the positions it is desired that the ca ebars shall occupy with respect to the pat of rotation of the beaters. In actual practice it is intended to substitute different ring-mounts having rooves struck from difierentcenters to provi e different adjustments, so as to change the relative position of the several bars with relation to the beaters. The purpose of riveting a plurality of bars together is to facilitate and quicken the' time in effecting a change in the adjustment of the radial distances of the cage from the axes of rotation of the hammers or beaters; but it is obvious that instead of grouping a plurality of cage-bars together the bars may be separately introduced.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is. I

The combination with a support having I a curved groove, of interchangeable ringmounts for engagement in said groove, said ring-mounts being provided respectively with grooves struck from different centers, and cage-bars for engagement with any of the grooves in the respective ring-mounts; substantially as described.
