IMPROVE r'LocK-GRINDER.
The Schedule referred to in these Letters Patent andmaking part of the same.,
To all whom it my concern Be itknown that I, ROBERT ALDRICH, of Forestdale, in the county tif-Providence and State of Rhode Island, have invented a new and' improved Flock- Grinder; and I do hereby declare that the following is a full, clear, and lexa-ct description thereof, which will enable others skilled in the art-to make and use the same, reference being had to lthe accompanying drawing forming part of this specification, in which- Figure 1 representsa side elevation, partly in .section, of my improved flock-grinder.
Figure 2 is an end view of the same.
Similar letters of reference indicate corresponding parts.
This invention relates to 'a new construction of Hock-grinder, and, more particularly, to anew method of securing the knives in the 'grinding-surfaces, with a view of adjusting .the same to dierent kinds of work, and to provide for .wear by the operation of grinding. a A
The invention consists in a new method of securing the knives-in the grooved cones. by means of remov able wedges, and of making the same adjustable by means ofsetscrews and fixed pins, as hereinafter more fully described.`
Ain 'the drawing, represents the frame of my improved vHock-grinder. l
On it are arranged tlie bearings of a horizontal shaft, B, which carries the conical linner vgrinder O.-
The said inner grinder is arranged to revolve within the stationary outer grinder 4or shellY I), which lis 'also of conical form, as is clearly shown in fig. 1.
The shaft B is longitudinally adjustable in the shell by means of a screw, a, so that the grinding-surfaces may thereby be set closer together or further apart.
The face of the cone O is nrovided with grooves,
which extend from end to end, being ontv somewhat spirally or obliquely along the surface. Into each groove are placed two knives, b b, which rest against the sides of said groove, and are held in place lby a wedge-shaped block, c;
This block is secured to the cone by means of screws, d d, or otherwise, and fills the groove between the 'knives b, to hold the latter in place;
The front end of each knife b is beveled, as in iig. 1, an-d restswith the beveled edge on a stud, e, that projects from the inner face of the groove.
lhe rear end of the knife is also beveled, and tits under a slanting shoulder, f.
A screw, g, fittedinto the rear or large part of the cone, serves to adjust the knife vertically, by sliding it forward in the groove. The knife can thus be adjusted so as to 'provide for wear at the edge.
The inner surface of the shellD is grooved, in the same way as the outer side of the cone, and provided with knives b', blocks c', studs e', and adj listing-screws,I
substantially in the same manner as said cone.
Having thus described myinvention,
I claim as new and desire to secure by Lettels Patent- 1.` The grinding-conc and shell C D, provided with grooves, in which the knives are, in pairs, secured by wedge-.shaped blocks, substantially as herein shown and described.
2. The studs e, applied to thc cone C, in combination with the screws g, for the purpose of holding and adjusting the knives, as set forth.
