MILTON F. WILLIAMS, OF ST. LOUIS, MISSOURI. ASSIGNOR TO WILLIAMS PATENT CRUSHER & PULVERIZER MISSOURI.

COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF SLICING-HAMMER.

Specification of Letters Patent. Patented ltlal'. 12, 1912.

Application filed August 28, 1911. Serial No. 646,532.

.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 machine equipped with my improved slicing hammer. Fig. 2 is a detailed view of the hammer.

This invention relates to a new and useful slicing hammers for disthe object being to construct a hammer having a reversible slicing blade whose active cutting point will operate upon the material fed into the machine and whose non-active cutting point will be guarded or protected and prevented from becoming dulled. by the contact of material therewith. Another feature of my present invention is to give to the shank on which the cutting blade is mounted a quarter turn and to provide said shank at its outer end with a rebent curved portion into which the slice of material will be initially received and to be further reduced by attrition, and then deflected to one side.

With these objects in view the invention consists in the construction, and combination of the several parts all as will hereinafter be described and afterward pointed out inthe claims.

In the drawings 1 indicates the casing of the machine, 2 the breaker roll, and 3 the grinding cage, 4 is a shaft extending transversely the rinding chamber and on which are mounte supporting disks 5 for the slicing hammers.

The slicing hammer shown consists ofia shank portion 6 the lower end of which is given a quarter turn at the point marked 6" after which said shank is provided with a refolded bent portion 6" forming a pocket at the heel portion of the hammer head. The hammer head proper is flat and rovided with an overhanging lip or shou der 6 under which the non-active cuttin edge of blade 7 is introduced when said b ade is arrangement blade in place rivets 8 are employed the openings for which are preferably in such position that the blade may be reversed.

The active cutting edge extends outis beveled so as to coincide with the beveled face of. the active cutting blade, as shown. When the slicing hammers are swung outwardly by centrifugal force, as shown in Fig. 1, the cutting blade is tangentially disposed so that its active cutting point lies radially outward, the blade being thus inclined to its arc of movement.

In operation'the material to be operated upon is cut or sliced by the blade and due to the beveled edge thereof is forced inwardly, eventually being received by the semi-circular pocket at the heel of the blade where it is whirled around and further disintegrated by attrition. The material'after leaving the pocket is deflected laterally by the quarterturn in the shank and may then move outwardly by centrifugal force to pass ghrough the openings in the grinding surace.

What I claim is:

1. A slicin hammer comprising a one end of wfii and refolded so that said end occupies a position substantially at rightangle's to the main body portion of said shank, and a blade fixed to the outside of the refolded portion with its cutting edge projecting in front of said refolded end portion.

2. A slicing hammer comprisin a shank adapted to be pivotally connecte to'a rotary member at one end, the opposite end of which shank occupies a position substantially at right angles to the plane occupied by the body of the shank, said lastmentioned end of the shank being provided in its outer side with a recess, and a blade fixed to the end of the shank and positioned within the recess with; its non-cutting edge positioned adjacent to the, shoulder at the end ofz-the recess.

3. A slicin hammer comprising a shank, one end of w ich is bent a uarter turn and re-folded to form a pocket for receiving the sliced material and ablade fixed to the outer side of the re-folded portion of the shank with its cutting edge projecting in front of the re-folded portion of said shank.

4. A slicing hammer comprising a shank shank,

wardly beyond the cutting head which head ch is bent a quarter of a turn I placed in working position. To secure 'ithe at its opposite end, of ablade applied to the end of the shank below the pocket with the cutting edge of said blade projecting in 15 front of the end of the shank below the pocket. i

In testimony whereof I hereunto afiix my signature in the presence of two witnesses, this 24th day of August, 1911.
