IVILLIAM SIMPSON, OF BATTLE CREEK, MICHIGAN.

MACHINE FOR BLANCHING PEANUTS.

SPECIFICATION forming part of Letters Patent No. 655,277, dated August Y, 1900.

Application filed June 9, 1899- Serial No. '719| (NO 1110581) To all whom it may concern.-

Be it known that LVVILLIAM SIMPSON, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, haveinvented certain new and useful Improvements in Machines for Blanching Nuts; and I do declare the following to be a full, clear, and exact description of the invention, 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, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in machines for removing the outer thin skin or close covering that holds the two parts of the nut-kernel together, and has for its object to produce a device that will accomplish this result by subjecting the shelled nut 'to a rubbin g action between corrugated or roughened plates that converge toward a horizontal line.

Referring to the accompanying drawings, showing my preferred form of construction, Figure 1 is a side elevation. Fig. 2 is'a sectional elevation taken through the middle of the machine, showing some parts in plan. Fig. 3 is a broken horizontal section of the reciprocating rubbing-plate, taken upon the line 3 3 of Fig. 1. Fig. t is a horizontal section of the stationary rubbing-plate 0n the line 4 4 of Fig. 2.

In the several views, A A are the two vertical side members of the frame, preferably made of wood and of the shape shown in Fig. 2. In the upperflaring part of each side member I form a pair of grooves c c by channeling or otherwise making a guideway, which grooves are made converging downwardly. A pair of stationary rubbing-plates G C have their side edges engaging the grooves c c, and any suitable clamping means, such as bolts J J, serve to securely hold the side members and rubbing-plates together, as shown in the views. The grooves c c extend from the top of the side members downward, and the rubbing-plates C C can be adjusted therein by simply loosening the bolts J J and sliding the plates toward or from their line of convergence. By the term stationary rubbingplates I mean that while the rubbing-plates are adjustable in the said grooves, when they are clamped therein they are stationary or fixed relative to the reciprocating rubbingplate hereinafter described.

Intermediate of the grooves c c in each side member is a vertical slot d, whose lower end is near the ends of the grooves c c. biog-plate D reci procates horizontally in these slots d d and is actuated by a handle or through a connecting-rod by a source of power, as may be desired. To adjust the rubbingplate I), I preferably use two blocks K K, through which passes the bolt J, as shown, and this bolt has a vertical movement in the lower part of the slots dd. The lower edge of the plate D reciprocates on these blocks K K as bearings, and by loosening the bolt J these blocks can be raised or lowered and clamped in such position.

The great advantage of this mill is that it blanches the kernels by simply separating the two sections inclosed by the skin without further breaking the sections of the kernels. This result is accomplished by so adjusting the relative positions of the rubbing-plates that when the corrugations of stationary and movable plates register the opening will be just the size to permit a separated half-sea tion of the kernel to drop through.

It will be obvious from the drawings that the side plates can be adjusted to and from the reciprocating plate without changing the angnlarity of these plates with respect to each other or to the reciprocating plate. Another advantage of this form of construction is that i this mode of adjustment does not change the capacity of the mill in the least.

A suitableinclined plate I may be provided to divert the nuts passing through the mill into a receiving vessel.

It is obvious that the mill may be arranged for reducing or grinding purposes by adjusting the rubbing-plates with their lower edges in very close proximity to each other.

Having thus described myinvention, what I claim is- 1. In a machine of the class described, the combination with the parallel side members of the frame having vertical slots and the vertical rubbing-plate adapted to reciprocate horizontally in said slots, of a pairof stationary rubbing-plates disposed in planes intersecting the path of said movable rubbing- Aruba tco plate, and means for adjusting the positions of said stationary rubbing-plates in their respective planes in a direction toward and from the line of intersection of said planes, substantially as and for the purposes set forth.

2. The combination in a machine of the class described, of a pair of parallel side members having a vertical slot in each member and said slots being oppositely disposed, each side member also being provided with a pair of grooves converging downwardly toward its vertical slot, a pair of rubbing-plates with their ends entering said grooves in said side members and adapted for adjustment toward and from the line of intersection of their planes, means for clamping said side members and said rubbing-plates together in various positions of said adjustment,- and a vertical rubbing-plate adapted to reciprocate horizontally in said opposite slots in said side members and between said convergingplates, substantially as and for the purposes set forth.

3. The combination in a machine of the class described, of a pair of parallelside members having a vertical slot in each member and said slots being oppositely disposed, each side member also being provided with a pair of grooves converging downwardly toward its vertical slot, a pair of rubbing-plates with their ends entering said grooves in said side members and adapted for adjustment toward and from the line of convergence of their planes, means for clamping said side members and said rubbing-plates together in various positions of said adjustment, a vertical rubbing-plate adapted to reciprocate horizontally in said opposite slots in said side members-and between said converging plates, and means for vertically adjusting the path of movement through said slots of the said reciprocating rubbing-plate, substantially as and for the purposes set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
