JOHN L. KELLOGG, OF BATTLE CREEK, MICHIGAN.

MACHINE FOR MANUFACTURING BISCUIT FROM CEREAL FLAKES.

To all whom it may concern:

Be it known that I, JOHN L. KELLoGe, a citizen of the United States, residing at Battle Creek, Michigan, have invented certain new and useful Improvements in Machines for Manufacturing Biscuit from Cereal Flakes, of which the following is a specification.

This invention relates to improvements in apparatus and process for manufacturing and baking biscuits from flaked cereals or similar material.

The objects of this invention are to provide an apparatus which will compress a mass of flakes that are delivered to the same into an even layer, cut the same into proper form for biscuits, heat and partially bake the same while they arein the compressed form in the cutters, which insures the integrity of the biscuits, and the moisture being evaporated from the material Within the cutters, insures a contraction of the mass and a consequent proper discharge of the biscuit from the cutter, so that the same can then be passed on and completely cooked without danger of mutilation.

Objects pertaining to details of construction will definitely appear from the detailed description to follow.

I accomplish the objects of my invention bv the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

An apparatus embodying my invention and for carrying out my improved process is clearly illustrated in the accompanying drawings, forming a part of this specification. in which: 1

Figure 1 is a longitudinal sectional view through an oven with my improved apparatus installed, portions being indicated diagrammatically, taken on a line corresponding to line 1-1 of Fig. 2, the furnace not being in section; Fig. 2 is a detail sectional view of the cutting, compressing and delivering apparatus, takenon a line corresponding to the irregular line 2--2 of Fig. 1; and Fig. 3 is an enlarged transverse sec tional view ofthe roller and carrier taken on a line corresponding to line 1 1 of Fig. 2.

In the drawing, the sectional views are taken looking in the direction of the little Specification of Letters Patent.

arrows at the ends of the section lines, and similar numerals refer to similar parts throughout the several views.

Considering the numbered parts of the drawing, the outer walls 1 of the oven are indicated diagrammatically, the furnace 2 being within the same. In the upper part of the furnace is supported an endless apron 3, which is carried on rollers l and 5 at each end thereof, the said apron being of flexible sheet metal or of any suitable material that will answer the purpose and withstand the temperature of the oven. Above this apron 3 is supported a series of aprons 6 parallel to each other on opposite rollers, 7 and 8, which aprons are of flexible sprocket chain construction or any suitable material that will serve the purpose. To these are secured a series of cutters 20, hereafter to be more thoroughly described. Vithin these aprons are series of compression rollers 12'13 for holding the proximate portions of such aprons toward each other, to co1npress any volume of flakes that may be delivered between the same.

The roller 7 is separated into sections by disk knives 7 which divide the flakes delivered thereto into longitudinal strips as wide as the biscuits are long, in the construction illustrated, but they could, of course, be divided into strips the same width as the hiscuits to be manufactured.

Flaked corn or wheat, or any other cereal, is delivered from the flaking machines through a suitable spout or hopper 11 onto the apron 8, where it is compressed and distributed by rollers 9 and 10 just outside of the oven and delivered inwardly between the lower apron 3 and the upper cutter belts or aprons 6, so that as the apparatus is actuated a thin layer of damp flakes as they come from the rollers is spread out on the apron?) by the rollers 9 and 10, and carried along and delivered between the aprons 3 and 6 under compression, and will be divided longitudinally by the disks 7, and the cutters of the belts will divide the same into biscuits. As the biscuits are advanced into the oven, the heat of the oven drives the moisture out and causes a contraction of the biscuits, so that when the same reach the opposite end of the oven they are readily discharged from between these compression aprons and slide roughly baked, the temperature of the oven i i The cutters 20. are se'cured'by suitable downaninclincd chute 1 1, which is arranged at-the inner end of these aprons, and are deposited on the endless apron 15 in the lowerpart of the oven. Thisendless apron 15 is carried on opposite rollers1617. Thebiscuits by the time they are carried-back tothe outlet of the oven on the apron 15 are thorand the speed of the aprons being regulated to, that end,'when they slide downfthe inclined plate 18 onto a carrier 19 or to a suit-V able receptacle for packing.

means to wingedilinksof the sprockets con 'stituting the saidbelt 6, and they havefup-. turned ends 21, transverse thereto, so that in passing around the roller 7 they will take a tangential position, and" the cutting ends 21 will strikedown upon the mass of flakes on the apron 3 beneath,dividing the same into' lengths as the layer is advanced between the rollers." As these cutters 20 overlap each other and the two aprons'are heldtogether by compression rollers, clamping pressure is applied to the'biscuits as they are advanced throu h the oven. Theheat drives the moistu're irolntliem, causlng'them to. shr nk so that when they reach the opposite end of the apron they drop readily from the cutter and 'paratus as indicated.

pass readily on their course through the ap! The'cut-tersl have shown are in the form preferred by me, but the mass offlakes might be'cut and put under pressure in the manner I have indicated either 'in molds when it is flout or not in molds, and the same be baked under clamping pressure as I have indicated,
