ORE-CRUSHER.
Specification of Letters Patent.
- Patented Dec. 17, 1912.
Application filed August as, 1911. Serial Nb. 646,531.
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 Ore-Crushers, 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 vertical section taken lengthwise through the center of an ore crusher of my improved construction. Fig. 2 is a vertical section taken on a line 2-2 of Fig. 1.
This invention relates to a new and useful improvement in crushing machinery of that type particularly designed for crushing or disintegrating ore, coal, shale, clay-or like material.
The principal objects of my invention are to provide a simple, inexpensive crushing machine which can be operated with little power which has comparatively large capacity and the parts of which can be easily and cheaply repaired when worn or broken from use.
To the above purposes my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described and claimed.
Referring by numerals to the accompanying drawings, 1 designates the horizontallydisposed cylindrical shell forming the body of the machine which shell is preferably constructed of heavy sheet metal and providcd in its lower portion with an opening 2 from which leads a discharge spout 3. Located in the ends of the shell or housing and fixed thereto in any suitable manner are heads 4 and 5 prcferably of cast metal and formed on or fixed to the inner face of the head 4 adjacent the outer edge thereof is an inwardly projecting flange 6 which forms a support for the ends of the bars forming the grate or grinding cylinder. Formed integral with the inner edge of the lower portion of this flange G is a vertically-disposed wall 7 which extends entirely across the lower portion of the head 4, and thus a space .Or chamber 8 is formed between said wall 7 and the lower portion of head 4. Located in the lower portion of the head 4 is an opening 9 which forms an outlet from the space 8 and leading from this opening 9 is a discharge spout 10.
Formed on or fixed to the inner face of the head 5 is an inwardly projecting annular flange 11 the diameteraof which is less than the diameter of the flange 6 and this flange 11 forms a supportfor the corresponding ends of the bars forming the grinding cage of the machine. Formed through the upper portion of the head 5 is an opening 12 and leading thereto is a hopper 13 by means of which the material to be crushed or disintegrated is delivered into the machine.
The grinding cylinder which forms an essential feature of my improved machine is com osed of a series of bars 14 preferably 0 steel appropriately spaced apart and the ends of these bars rest upon the flanges 6 and 11 heretofore described and said bars are held in proper position by clamping rings 15 which latter are fixed in any suitable manner to the heads 4 and 5.
As heretofore stated the flange 11 is smaller in diameter than the flange 6 and for this reason the bars,14 when properly positioned form a grinding cage'which tapers toward the head 5, thus the material to be crushed or disintegrated which is fed into the machine through the hopper 13 will by gravity naturally pass to the opposite and larger end 'of the grinding cylinder but said material will be held within the cylinder to'be engaged by the grinding hammers by the wall 7.
During the operation, of my improved machine the material to be crushed or disintegrated is delivered into the h0pper 13 and passes therefrom through the opening 12 into the grinding chamber. The shaft 18 is driven at a suitable speed andthefiexlble .hamm'ers comprising the heads 23 and the bars 22 assume radial positions with respect to the shaft 18 due to centrifugal force. The material fed into the machine will be struck by the rapidly moving hammers and thrown with considerable force against the grind in cage and thus said material will be very quickly crushed and disintegrated. The finer particles of material will discharge between the bars forming the grinding cage and will pass out of the grinding chamber through the discharge spout 3 while the larger pieces of material will be carried around within thegrinding cage and repeatedly struck by the flexible hammers until completely disintegrated. Oversized pieces of particularly hard material which are not readily disintegrated will be carried around by the flexible hammers and thrown to the upper part of the grinding cage and eventually these large or oversized pieces of material will fall into the space 8 between the head 4 and wall 7 and will discharge from said space through the spout 10.
A grinding or crushing machine of my improved construction is comparatively simle, can be easily and cheaply operated can readily repaired andis particularly a a tcan be made and substituted for those herein shown and described without departing from the spirit of my invention.
I claim:
A crusher comprisin in combination a tapering perforate grin ing cage having an inlet end and an outlet end, the outlet end of said cage being of greater diameter than the inlet end, a casing surrounding said cage and provided with an inlet, an voutlet, and a second outlet intermediate said inlet and said outlet, a revoluble shaft extendin through said cage, flexible beaters mount thereon, and a wall interposed between the lower portion of the cage and the outlet of the casing for the purpose described.
In testimony whereof I hereunto afiix my signature in the presence of two witnesses, this 24th day of August, 1911.
MILTON F. WILLIAMS.
