To all whom it may concern:

I3e it known that I, MILTON F, WILLIAMS, a citlzen'of the United States, residing at St.

Louis, Missouri, have invented a certain new and useful Improvement in Dumping-Cages for Crushers and Pulverizers, of which thefollowing is a'full, clear, and exact descrilp e tion, such as will enable others skilled in t art to which it appertains to make and use the same, reference being had to the accompanymg drawin s, forming part of this specification, in whic h Figure 1 is a sectional view through my improvedmachine. Fig. 2 is a detail view of the dum ing oage. Fig. 3 is a sectional view on the line 3 3 of Fig. 1, and Fig.4 is a perspeQtive view showingone o'f'the adjustingwedges in operative engagement with the laterally-extending projection on the grindingsurface frame.

This invention relates to a new and useful improvement in dum ing-cages for crushers andipulverizers, the o ject being to construct a cage in such manner that when the machine chokes .it is possible to dump the contents thereof without raising the cover and removing the material from the top. y

In the operation of my machine, especially where electric motors are employed as a driving medium, it sometimes happens that the fuse will blow out or other accidents'happen during the time that the machine is in operation, causing the machine to stop and leaving the material being operated upon. in the ma- Under these circumstances it-is impossible to start the machine without first removing such material, it being necessary to get the machine up to full speed before introdueing the mate-rial thereinto to be reduced.

My present invention therefore consists in making the grinding surface or cage .with

which the revolving heaterscooperate to reduce the material wholly or partly movable, means for moving the same extending to the exterior of the machine,wherebyin the event that the machine stops with a load or become choked it is possible for the operator to dump the contents of the cage and free the machine.

In the drawings, 1 indicates 1 the side frames, and 2 the removable cover.

3 is the adjustablebreaker plate, arranged at the feed end of the machine and on which the material entering the machine is first struck by the revolvingbeaters or hammers 4, mounted in suitable supports, in this instance said supports being shown as crossed arms 5, having holes in their ends, whereby the hammers may be adjustably mounted therein.

6 indicates a portion of the cage or grindingsurface, preferably that located at'the back tionarily mounted in the side frames.

7 indicates a movable portion of the cage, the same being mounted in the side frames 8,

rod 9. These side frames 8 are connected in any suitable manner and preferably-carry a cross-bar 10 at their free ends, in which are mounted screw-eyes 1-1. Chains '12 are sethe rear end thereof. On this winding-shaft is a ratchet-wheel 14, with which cooperates to the shaft whereby the same may be rotated.

in dotted lines in Fig. 1, and in the event that the machine chokes the pawl 15 is raised and to drop, as shown by fulllines in said Fig. 1. In this position the major portion'of the contents of the machine .is discharged through the bottom thereof, and after said discharge through its hand-wheel to raise the cage to its normal operating position. If desired, theside frames 8 may be provided with threaded openings 17, which are designed to register cage is in its normal operating position. Screws 19 may be inserted through the slots to the striking-points of the hammers 4. These wedge-blocks are useful also in adjusting the movable section 7 to take up the wear of the hammers.

3. In a machine of the character described the combination ofthe casing, revolving hammers or beaters arranged therein, a pivotallymounted frame inside of the casing and provided with a rigid grinding-surface, removable devices projecting laterally from said frame through openings in'the side walls of the casing, and wedges cooperating with said devices for. adjusting the free end of the frame to take up wear between the grindingsurface and the ends of the hammers.

4. In a machine of the character described, the combination with a casing, pwotallymounted revolving hammers or heaters, a

frame pivotally-mounted in said casing, a

grinding-surface carried by said frame, a flexible device connected to said frame,

winding mechanism for said flexible device,

and independent means for adjusting the frame when in operating position substantially as described.

5. In a machine of the character described, the combination of a casing, pivoted revolving hammers or heaters, a pivoted frame mounted in the casing, a grinding-surface carried by said frame, a chain connected to said grinding-surface, a winding mechanism cooperating with said chain, removable projections which are designed to be connected to and disconnected from said frame from' the outside of the casing, and means cooperating with said projections for tdJUSlllIlg the free ends of said pivoted frame and its carried grinding-surface when the same-is in operating position; substantially as described.

6. In a machine of the class described, the

combination with a casing, of revolving beaters mounted therein, a pivotally-mounted grinding-surface arranged inside of the casing and provided with members that project laierally through slots in the side walls of the casing, and wedges at each side of the casing cooperating with the laterally-projecting members on the grinding-surface to change its position relatively to the ends of the beaters; substantially as described.
