A CORPORATION OF MISSOURI.
Specification of Letters Patent.
Patented Nov. 20, 1906.
Application filed July 24, 1905. Serial No. 271,018.
' To all 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 Dumping-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 I I Figure 1 is a vertical sectional view through my improved machine. Fig. 2 is a sectional view on the line 2 2 of Fig. 1, and Fig. 3 is a detail view of a portion of the cage or grinding-surface. I
This invention relates to a new and useful improvement in dumping-cages for crushers and pulverizers, the object being to construct a cage in such mannel that when the machine chokes is it possible to dump the contents thereof without raising the cover and removing the material from the top.
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 hap pen during the time that the machine is in operation, causing the machine to stop and leaving the material being operated upon in the machine. Under thesecircumstances it first removing such material, it being necessary toiget the machine up to full speed before introducing the material thereinto to be reduced. I I
My present invention therefore consists in making the grinding-surface or cage, with which the revolving beaters cooperate to reduce the material, wholly or partly movable, means for moving thesame extending to the exterior of the machine, whereby in the event that the machine stops with a load or becomes choked it is possible for the operator to dump the contents of the cage and free the machine.
In the drawings,'1 indicates the side plates of the casing, and 2 is the cover. 3 indicates the breaker-plate, arranged at the front end of the machine and on which the material is first operated upon by the revolving hammers or boaters 4:, which are pivotally mounted in the hammer-supports 5, arranged on a transversely-disposed shaft 6. 7
indicates a cage or grinding-surface which cooperates with the revolving hammers or heaters 4', the side supporting-bars of which are pivotally mounted at Sat the rear end of the machine, so that said cage or grindingsurface can swing down to the position shown in dotted lines in Fig. 1. The free end of the cage is provided with devices 9, which ex- .tend'upwardly through openings formed in ofisets in the side walls of the casing, said upwardly-extending devices being preferably continuations of across supporting-rod 10,, passing through the sidebars of the cage. The upperends of these devices 9 are provided with openings 11, with which cooperate wedge-keys 12, that rest on horizontallydisposed portions of saidoifsets- A wire rope, chain, orcable 13 is-also connected to the devices 9 y In operating position the cage or grinding surface is held in place by the wedge-keys 12, which pass through the upwardl projecting devices 9 and rest upon the o setsinthe "side walls of the casing,.and by driving these wedge-keys inwardly the free end of the cage may be adjusted to take up wearof the en s of the revolving ,hammers or beaters' In the/event that it is desired to dump the con' tents of the machine the wedge-keys 12 are driven out of the devices 9 and the o erator holding the rope or cable 13-permits t e cage to swing down to the position shown indot ted lines in Fig. 1, in which position the contentsof the machine will be discharged.
To restore the cage to normal position,.the' ropes or cables 13 are operated to raise the free end of the cage unt1l the devices 9 project up through their registering openings in the ofisets in the side walls of the casing, at which time the wedge-keys may be driven through the openings 11 to hold the cage in position.
Having thus described the invention, what is claimedas new, and desired to be secured by Letters Patent, is
1. In a machine of the character described, the combination of a casing, revolving hammers or heaters, a pivoted cage or grindingsurface, upwardl-extending devices on the free ends of sai cage or grinding-surface which pass upwardly throughopenings in free ends of sai the casing, and means cooperating with said upwardly-extending devices for locking the ca e in normal operating position; substantia llyas described.
2 In a machine of the character described,
the combination of a casing, revolving ham position; substantially as described.
3. In a machine'of the character described, the combination of a casing havingv lateral oflsets in its side walls, revolving hammers or heaters, a pivotallymounted cage or grinding-surface having upwardly-extending lateral ofisets in the side Wa devices passing through openings in the V ls of the casing, means cooperating with said upwardly-extending devices and resting on horizontal portions of said oflsets for adjustably supportingthe cage in normal operating position, and {chainsor cables connected to said upwardly-extending devices whereby said cage may be swung on its pivot to dump the contents of the machine and restore it to normal position; substantially as described.
In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 14th day of July, 1905.
