DAVID GUELBAUM, OF SYRACUSE, NEW YORK.

GRAIN-CUTTING MACHINE.

Application filed October 21, 1922. Serial No. 596,176.

T 0 all whom t may concern.'

Be it known that I, DAviD GUELBAUM, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain.

` new and useful Grain-Cutting Machine, of

which the following is a specification.

My invention of a grain cutting machine has for its object the cutting up of cereal grains, such as wheat, rye, barley, into particles, coarse or fine, without cracking or crushing of the grains and without powdered wastage, so that the cuttings obtained are less exposed to the drying deodorizing atmospheric action and the nutritive essence of the grains is better preserved, than in other grain disintegrators, and such clean cereal cuttings are therefore better adapted for dietary purposes, especially for the makin of bread from un-milled cereal grains. y invention comprises the above set forth novel features, embodied in combinations and constructions as hereinafter set forth and claimed, and as illustrated in the accompanying drawings, in which similar characters designate the same corresponding parts in all the views.

Fig. 1 is a vertical section of my grain cutting machine.

Fig. 2 is a cross section of the same, show- .ing the cutting edges. y

iig. 3 shows the adaptation of the machine to a belt drive with variable speed.

Fig. 4 sho-ws a modification of the inner cutting cylinder, provided with a separate cutting sheet steel cover.

As seen on Fig. 1, my grain cutting machine consists of the grain hopper 1 having an offset cylindrical flanged top 2 and an open tapered flanged bottom with a supporting ledge 3 inside. Into that ybottom of the hopper is fitted in the stationary o-uter cylinder 4 resting on the ledge 3 and secured by the tap bolts 5. By loosening these bolts the cylinder 4 can easily be taken out and replaced by another one to suit different kinds of grains when desired.

This stationary outer cylinder 4 is provided with longitudinal slots with beveled o.' edges, as shown on Figs. 1 and 2; the` solid strip 6 in the middle of the cylinder, shown on Fig. 1, serves merely as a re-enforcement. i Y

. Inside the stationary outer cylinder 4 is tted slidingly the inner rotary cutting cylinder 7, provided with similar longitudinal slots with sharper beveled cutting edges, as Shown on Figs. 1 and 2.

The top of the inner cutting cylinder 7 fits into the bottom of the cone shaped cover 8, shown in section on Fig. 1, and is held securely by the tap bolts 9; by loosening these bolts the cutting cylinder can easily be taken out and replaced by another one when desired. The rim 10 at the bottom of the cover 8 loosely overlaps the top of the stationary outer cylinder 4 to protect it from injury, as shown on F 1.

The cone shaped cover 8 terminates at its top with the shoulder 11 and projecting pivot on which is keyseated the hub of the handwheel 12 and secured by the tap bolt and washer 13, as shown on Fig. 1. This hand wheel is provided with the radial arms 14 and the circular rim 15 resting on the ianged oifset 2 on top of the grain hopper 1 and fitting slidingly into same. The rim 15 of the hand wheel is held fast to its seat by several clips 16 bolted on to the top iange of the hopper, as shown on Fig. 1. j

Thus, the hand wheel 12 carrying the cone shaped cover 8 with the cutting cylinder 7 is reliably supported and guided, taking off all side strains from the cutting cylinder.` By un-fastening the clips 16, the hand wheel 12 with the cover 8 and the inner cylinder 7 can be bodily taken out vof the grain hopper 1. i

On the arms 14 of the hand wheel, near its rim 15, are cast on tl'e bos'ses17, to one of which is fastened ,the handle 18 for rotating the hand wheel. i To the bottomof these bosses 17 are fastened the scoops or stirrers 19, consisting preferably of twisted plates, as shown on Fig. 1 and in section on Fig. 2. These scoops,rotated by the` lhand wheel, in the direction shown in plan Fig. 2, shovel and thrust the grains through the longitudi-` nal slots of the outer stationary cylinder 4, the grains'being met and "cut by the sharp cutting edges of the rotating inner cylinder 7. l

One'of the clips 16 holdingthe handwheel fast to its seat isprovided aty its top with the button headed setscrew 20, piercing through slightly into the rim 15 of the handwheel, for they purpose of holding the handwheel fast to the hopper, when the machine is not working, in such al position, that the strips of the innercylinde'r 7 cover the slots of the outer stationary cylinder 4i, and no grains'can pass through the slots. c

The grain hopper 1 is mounted with its bottom flange on top of the wooden box 21, provided with the drawer 22 inside, for collecting the discharged grain cuttings, as they drop off the inside surface of the cutting cylinder 7.

The action of the machine is as follows: Vhen the machine is not working and the hand wheel 12 is held fast by the button headed setscrew 20, the strips of the inner cylinder 7 cover the slots of the outer cylinder 4L, and no grains can pass through. rIhe hopper 1 is then filled with grain, the hand screw 2O is loosened and the hand wheel rotated by the handle 18 in clock wise direction, as shown in plan on Fig, 2. rffhe rotating 'scoops 19 shovel and thrust the grains through the longitudinal slots of the stationary outer cylinder et, the projecting and passing grains being met yand cut by the rotating` cutting knives of the inner cylinder 7.

By loosening the fastening bolts of the scoops and turning them to the position shown in dotted line 19 on Fig. 2, the direction of rotation of the hand wheel may be reversed to opposite clock wise motion, and the opposite cutting edges on the inner cylinder are then utilized.

lThe more cutting knives are passing per minute over the slots of the stationary outer cylinder, the finer evidently will the cuttings be. Therefore, by rotating` the hand wheel 12 faster or slower, the obtained grain cuttings will accordingly be finer or coarser, as desired.

Fig. 3 shows the top portion of the machine adapted for a belt drive with variable speed. For that purpose the projecting pivot on top of the cover 8 and the hub of the hand wheel 12 are extended upward, and a step pulley is key seated and setscrewed on the extended hub.

F ig. 4f shows amodification of the inner cutting cylinder. Instead of the cutting c knives being cast inl one with the cylinder,

the latter one is provided with the thin sheet steel cover 24, made in one piece, or in segments, and fastened to the outer surface of theinner cylinder by, countersunk setscrews,

or soldered on, the sharp edges on thev slots of the sheet forming the cutting knives, which can thus 'be removed kand re-sharpened, or replaced by new ones, as desired.
