D. S. \VAGENER, OF PENN YAN, NEWV YORK.

FLOURING-MILL.

Specification of Letters Patent No. 13,610, dated September 25, 1855.

To all whom it may concern Be it known that I, D. S. VVAGENER, of Pen Yan, in Yates county, in the State of New York, have invented certain new and useful Improvements in Flouring Mills; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure 1 is a front elevation. Fig. 2 1s a vertical section. Fig. 3 is an inverted section of the case or air tight chambers.

In the construction of my machine Fig. 1, letter A, the air tight chamber resting on the casement surounding the stones or runner; a, the door opening into the chamber when necessary to examine the interior of the same; 6, pin and staple for fastening the door; 0, the hopper; (Z the screw for regulating the shoe; 6, e, the posts of the frame; f, the mouth or spout for delivering the meal or flour; B the ventilating tube extending from the outside of the building into the air tight chamber; 0, the suction tube connecting with tube B, in the air tight chamber, and running beneath the shoe, and above the eye of the millstone to the fanners; D, g, the driving pulley. E the case inclosing the runner or stones which I convert into a hot air chamber or extra receiver in which the heated air accumulates. F, the tube for carrying off the hot air; 1, the throat in fanner D, shown in dotted lines; 2, 3, and A the floors.

Fig. 2, A the air tight chamber, 0, hopper, (Z the shoe, 6, e, the posts of the frame, B, the ventilating tube, C, the suction tube, D, the fanners, 1, the throat, g, the driving pulley, 2, 3, and 4 represent different floors of the building, E, the hot air chamber, G, the partition for excluding the hot air from the air tight chamber, A. F, the tube for carrying 01f the heated air. h, the throat or scroll for receiving the air, H, the runner, H the bed-stone, I the spindle, and bearings. K, that portion of the tube where tubes B, and C, connect; at this part of the tube there is an aperture directly under the shoe into which the grain falls, and is something like a funnel; the opening below is just large enough to let the grain fall through that portion of the tube where the current passes and which is shown in dotted lines at K only as fast as it can be ground, thus having the full force of the current on thegrain and clearing it of all impurities.

Fig. 3, G, the inner portion. E, the hot air case, 70, the throat for arresting the hot air, and causing it to enter tube F.

In the operation of my machine I construct chamber A air tight, except Where the grain passes from the hopper. By this means I exclude all dust from the eye of the stone. I then introduce into chamber A, tube B, from the outside of the building, or a clean apartment belonging thereto, connecting it in chamber A with tube C, and fanner D, or its equivalent. I then put my blower in motion, by any ordinary connection, and as the blower is made rapidly to revolve a suction is created through tubes B and C passing rapidly through the grain as it falls from the shoe through the tube into the eye of the stone; the air tight chamber excluding all dust from concentrating in the eye of the stone as in the mills ,in ordinary grinding. The entire force of the current thus introduced passes undisturbed through the grain, cleansing it entirely of the dust and all light substances, which may have remained in the wheat after the cleaning process usual is undergone, or which may have collected While in the mill. A portion of the air thus introduced into the air tight chamber A, can escape with the grain and ventilate the stones; as the constant friction of the stone causes heat it is necessary for me to provide for carrying it off, or else itwould rise up, and condense in my air tight chamber, and cause the inside of the chamber to sweat, and become moist; and if allowed to do so, would pass down through the eye of the stone, and gradually retard the grinding process, by causing a dampness in the grain and flour, and thereby heating it, and greatly injuring the same. To avoid this I construct an extra chamber, or casing E. This chamber surrounds the entire bed of the stone, and is formed by means of the extra partition Gr, which is made stationary on the under side of the top of the casing and extends down to the back of the stone, thereby excluding the hot air from the air tight chamber. As the stone revolves the centrifugal force of the stone gives a circular current to the air, and causing it to tend outward, and around with the stone until it comes to the throat 72., Where it is checked, and passes up through the tube F, and is mingled with claim as new, and desire to secure by Letters Patent is The arrangement of tubes B and C connected by the supplemental shoe K Within the air tight chamber A, in the manner described and for the purpose specified.
