JOSEPH HENRY,both of'jthe city of Balf .timore, State of Maryland, have inyented certain new and useful Improvements inMachines or Cracking" Wheat andwe hereb declare $Y f bd a ib lqws; refe e e hed'll t a y n -d aw n s; h l 1 ure 1 r p es nt a f n leven said machine,"the cover beinglremovedj in or?- d o w h li e na t n tme ion 0f.

The objectlof our invention is to fiirnish a machine for-produ'ci ng in a rapidand easy ,manner a superior gradeof what is known as cracked wheat,- now extensively used as an article of food; i ii lnjcracking'th'e g ins it is desirable-that thefsame should be, merely subj ected to pressre, and not scratched or abraded in anyway. A y gr d g i ac o fon. t .par .-,0f, I th mchine i results in "diminishing theiquantity of n od c in h orm f tra k d. whea (a siderable portion being reduced 1 to "coarse flo'u'r,) besides impairing the appearance of p the product, and, also," as a natural consequen e, its w hi In *n ss hr n I o r.m h n -th am er Su je e tq 's mr e pressure,whereb 't eyga e ea d tofcracl;

countersunk beneath the cylindrical surfaces of the rolls, so that when their unmilled surfaces are brought in contact a space will be left between the milled portions, which space will determine the size of the particles of cracked wheat.
The bearings of one of the rolls are made may be taken up from time to time. The
shaft 1) of one of the rolls terminates in the ordinary square or polygonal head, for the attachment of a crank, E.
It will be observed that the upper edges of the castings A A, which are immediately beneath the hopper O, are extended into the interior of the box a distance equal to the width of the unmilled edges of the rolls, the parts a a thus formed being beveled, as shown, in order to deliver the grain freely to the rolls; the object of the described construction being to prevent any grains from falling between the unmilled edges of the rolls.
The casting A is secured to a suitable support by means of screws e e e, to insert which it is, of course, necessary to take the box apart and remove the rolls.
Within the casting A are secured a pair of scrapers, D D, attached by means of screws 9 g. The scrapers are arranged so as to press slightly upon the milled portions of the rolls, and remove any particles of grain which may adhere thereto.
The operation of the device is evident from the foregoing description of its construction. The hopper 0 being fed with grain, and'the rolls being pressed together by means of the screws -c c, and caused to revolve by the crank E, the grain passes uniformly between the rolls and out at the bottom of the machine.
It is obvious that, instead of driving the roll B by frictional contact with the other roll, the two may be geared together by ordinary pinions.
- While in the drawings we have illustrated butone roll as being recessed upon the milled surface, both may be so constructed.
The object in milling the rolls is simply to give them a hold upon the grain, and as it is desirable that the surface of the grain should not be scratched to any great extent, the milling should be quite fine.
Whilewe have illustrated the milling as consistingof fine lines crossing at right angles, other forms of roughening, such as stippling, will answer, the object being as stated, to cause the rolls to seize and draw the grains between them. I
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
,1. In a machine for cracking wheat, a pair of rolls the cylindrical surfaces of which are recessed and milled upon one or both of the rolls, substantially as described.
2. In a machine for cracking wheat, a pair of rolls having a part of their cy1i d i 1 Sup V 1 face milled, in combination with a chute extended inwardly, in order to cover only the unmilled portion of the rolls, as and for the purpose described.
