E. CLARK.
Mill Bolt.
Patented Jan. 5, 1858.
UNITED STATES PATENT OFFICE.
EDWVIN CLARK, OF LANCASTER, PENNSYLVANIA.
FLOURING-MILL.
Specification of Letters Patent No. 19,016,datd January 5, 1858.
T 0 all whom it may concern:
Be it known that I, Eowix CLARK, of the city and county of Lancaster and State of Pennsylvania, have invented certain new and useful Improven'lents in Flour-Mills; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in which Figure 1, represents an elevation of said mill. Fig. 2, represents a longitudinal Vertical section through the same. Fig. 3, represents a vertical cross section through said mill.
The nature of my invention relates to the manner of separating the various products of grinding when they leave the bolt of the mill.
To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.
A represents the frame which supports the grinding apparatus of the mill; the grinding apparatus is inclosed within a casing B, in the usual manner.
G, and D, are two elevators which pass over revolving pulleys in the casing E, and which serve to convey the flour from the grinding stones to the bolt.
F, represents the frame of the bolting chest; it supports at its top the conveyer G, which revolves within its casing H.
1 represents the bolt constructed in the usual manner and revolving within the bolting chest; the flour is introduced into said bolt by means of spout K, extending downward from the bottom of the casing H. The shape of the bolting chest is represented in a. cross sect-ion in Fig. 3; the flour as it is discharged from the bolt drops within the hopper formed by the inclined sides L, M, of the bolting chest. J, J, Fig. 2, are two partitions within said hopper which serve to separate the ship stuff, and the middlings as they escape from the lower part of the bolt, and the bran and ship stufi escape through the passages N, O, of the hopper while the middlings that are to be ground over, drop into the section P, of the hopper, and escape through passage a to the conveyer Q. The aperture 64 can be opened and closed by means of a slide 6 which slide is connected with an exterior slide (Z, which latter serves to open and close the aperture h. The two slides are connected by a rod 6, on therear end of slide cl, passing through an eye which is attached at g to the front end of slide (l. Thus it will be seen that when the aperture 72, is partiallv or entirely opened by operating slide (Z, slide Z), will be closed to the same extent. This operation of the slides b, and d, affords the means of withdrawing such a quality of the middlings of the mill as are too light to be ground over again, and the slides can be adjusted to such a nicety as that, just the desired quality of flour will descend through aperture a to the conveyer Q, while the light middlings will drop on the closed slide 6, and escape through aperture h.
The operation of this machine is as follows: Rotary motion being given to the driving shaft R, the grinding apparatus within the casing B, is set in motion and the elevators and conveyers of the machine are operated by means of the gearings n, 0, p, g, r, and the ground flour passes through the spout K, into the box S, whence it passes through aperture 121, (in dotted lines) into the casing E, and is carried up by the elevator C, and is discharged into the bar H; the conveyer G, conveys the flour through the case H, into the spout K, whence it drops into the bolt I, the fine flour escaping through the upper part of the bolt, and dropping into the box T, of conveyer Q, while the middlings drop on shelf P, and partly escape through passage (1, and down into the conveyer T, and partly through passage 71, and
the bran and ship stuff escape through the apertures IT, 0. The flour in box T is caused to pass through apertures 00 the size and positions of which can be adjusted in such a manner that flour of a certain degree of fineness may escape, while the coarser flour is moved on in box T, and is discharged through aperture t, into the case E, whence it is conveyed by the elevator D, into the spout U, to be passed to the grinding apparatus for a second grinding. The flour Which passes through the apertures w, drops into box V, the finest parts thereof passing through the adjustable apertures 2, While the coarser parts are conveyed by the conveyer W to the elevator C, which returns them to the box H, and bolt I, to be sub mitted to a second bolting operation.
A mill thus constructed is capable of doing the finest kind of Work, While it is equally portable as those mills which only perform coarse grinding and but slight separating. 7
Having thus fully described the nature of my invention What I claim therein as new and desire to secure by Letters Patent is,
In combination With the bolt I, and hopper formed by the sides L, M, the separate conveyers Q, W, and the slides 6, cl, con. nected together, and operating in the manner set forth, for the purpose of making such a separation of the ground material, as Will obviate the necessity of requiring the bolt to carry the material any farther than is actually necessary to bolt it, to avoid, all danger of clogging, While conveying the sep arate qualities to their exit, or elevators, and prevent any possibility, by the perfect separation, of returning that .Which is too light to be reground, to the stones, as explained.
EDWIN CLARK.
