Letters Patent N0. 108,246, dated October 11, 1870.

The Scheule referred to :in` these Letters Patent and making part of the same.

I, JACOB Fieitisenn, of Kingsville, in the county of Ashtabula and State of Ohio, have invented an Improved Vermiu and Bnfrproof Sectional Flour-Bolt, of which the following is a specication.

The first part of my invention relates to the com struction cf the reel of a Hour-bolt, in sections or compartments, cach covered with a different uumber of boltiug-cloth, separated by transverse partitions, and communicating with each other by a centrai aperture in each partition the object of this part of my invention beingto detain the fiour in its passage through the reel over the different cloths, to perfeet the separation of the different qualities of cur.

.Lhe second part of my invention relates to the use ot metallic cones, connected and o'perated by a longitudinal rod in the axis of the reel, to serve, first, as guides in conducting the iour passing through cach compartment or division of the reel to the ceutml apertures in the partitions separat-ing it from the next succeeding division; and, secondly, as valves to close said apertures, and regulate the opening thereof, and, consequently, the passage of the flour through the reel.

A The third part ot' my invention relates to the combination of a solid head-plate with the upper end of the reel, this plate being, however, provided with a series of concentric feed-ways or apertures cut through the same, near its circumference, for feed- ,ing the flour into the bolt; the object of this part of my invention being, not only to facilitate the exclusion of bugs and extraneous substances, injurious to the cloths, but also to distribute the flour passing into the reel against the inner surface of the bolting-cloth covering the saine.

The fourth part of my invention relates to an auxiliary device for the protection of the reel against bugs and vermin, to be used in combination with the concentric feed-ways, in the upper head of the reel, and with an outer wire screen or casing, inclosing the entire length thereof, said device con. sisting ot' a conica-l metallic cap, to cover the upper end of the bolt, and extend to its rim, or iieaily so, and provided with a wire sieve, to cover' its feedopening.

The fifth part of my invention ,relates to the combination of journal-arms with the heads of my improved sectional bolt, to avoid the use of a shaft extending through the saine, and to permit the use and operation of central valves in connection with central openings in the partitions dividing the several sections or compartments of the reel.

The sixth part of my invention relates to the combination of longitudinal fall-boards oi strips,

passing through the reel in continual contact with the cloths, and causing it to pass over the same with a sliding motion, as the reel revolves, to facilitate the separation of its particles.

-The seventh part of my invention relates to the' combination of radial projecting guide-strips, upon the upper side of each partition in the reel with the projecting conical surfaces of the valves, and with radial vanes or strips projecting therefrom; the object of this part of `my invention being to facilitate lthe passage of the Hour successively from one compartment in the series to the next.

'Ilie eighth part of my invention relates to .the combination of a set-screw, threaded upon the end of the rod carrying and connecting the conica-l valves, covering and regulating the central communicating apertures between the several sections or compartmentsof my improved bolt, with a central, longitudi nal, threaded aperture in the lower journal of the bolt; this threaded end of the rod heilig made to project through the journal, and provided with a handwlieel, to facilitate its operation; the object of this part of my invention being to provide for an adjustnient of the valves in the bolt, and, consequently, to regulate the rapidity of the flow of flour through the same, without arresting the reel in its revolutions.

In the accompanying drawing- Figure lis a longitudinal central section of my improved Hour-bolt, in the line a' a' of fig. 2, with its ,valves wide open.

Figure 2 is a transverse section thereof in the line y y effin'. l, lookiug'to the left.

Figure 3, a View of the upper head of the reel, with its outer cap removed, illustrating the arrangement of the concentric feeding-apertures therein, and ofthe radial discharging-chaiiiicls, extending from its central recess.

Figure 4, a view, in perspective, of one of the con ical valves, closing and regulating the openings between the compartments of the reel.

A represents an octagoual bolting-reel, but which niay be constructed of a hexagonal or otherwisepolygonal form.

This reel is constructed of the ribs a a, coverediexteriorly in the usual manner with bolting-cloth of proper texture.

instead, however, of being left open at each end,

yand frontend to end, as in tlze ordinary b'oltingreels in use, its ends are closed by means of circular plates or heads, B B', secured to the ends of the ribs a a, and it is divided interiorly `by transverse" partitions U, into two or more sections or compartments, each of which is covered with a different numher of bolting-cloth.

The heads B B project radially beyond the circumference of the rcel, 'and to their perimeter-s are secured the ends of a wire cylinder, I), completely encircling the rcel A. Y Y

The meshes of this cylinder are made close enough to elfectually prevent an entrance of the black bug vand to facilitate a distribution of the Hour thereto,

I place upon this head a second plate, fig. 1, of smaller diameter, through which the openings E E are extended, and secure thereto an outer, conical metallic cap, F, having a central opening, f, through which the journal of the reel projects, aml the flour to be bolted is introduced, and insert a cylindrical wire sieve Gr, so as to extend from the rim of its opening f to the face of the plate B, as shown in tiff. 1.

A recess, h, having inwardly-beveled edges, and of a circumference somewhat smaller' than that of the sieve G, is cut centrally into the head-plate B and radial channels 'i (sec liv. tt) are cnt therefrom to the outer rim of said. plate, andvcovered with me- Y tallic strips jj, to form conducting apertures, through'l which any foreign matters, arrested by the sieve., and, falling to the lower end thereof, are immediatelyy discharged.

The lower head B is strengthened by au outer plate, B", corresponding to the piate- B" ou the upper head.

.This lower head, and each of the partitions C C of the reel are pierced with central apertures m, in size about one-half the diameter of the reel for the passage of the flour through the bolt.

These apertures are ariug or outwardly beveled on their lower edges, and are fitted with cones l P, working thcrcinto from the upper side, as fully illustrated in fig. 1.

llfhesc cones or valves l l ure all secured upon a central rod, Q, passing centrallythrough the joui'- nal at the lower end of the reel, and working into au aperture bored for the purpose in its upper journal, so that a longitudinal .increment toward the lower end of the rcel will simultaneously close all of t-he communicating openings in the partitions of the reel, and the discharge-opening at its lower end, and a reverse rmwermultt thereof will open them. j

Each cone is provided with thin, radial flanges r 'r, projecting out from its conical surface, as far as its perimeter, (see fig. 4,) and nhich, fitting into corresponding grooves in the rim ofthe aperture to bc closed by the conc, serve as guides thereto.

The journals N N of the bolt may be secured. to each head in any suitable manner, so as to project centrally therefrom.

In the accompanying drawing l have illustrated the upper journal N', as secured to a plate, p, litting against vthe inner face of the head B, and projecting thence outwardly through the head, and the lower journal N, as secured te the lower head-plate B, by means of arms or brackets S S spanning the central discharge-aperture therein.

a central aperture,..properly-threaded, to receive the end of the valve-rod Q, which is likewise threaded to screw therein.

The end of the valve-rod projecting through the journal is provided with a hand-wheel, YV, by means whereof it is turned to operate the valves.

The ribs c c arcbeveled on their inner sides (which project within the reel, see tig. 2,) to form an angle ot' forty-five degrees, and a' strip or narrow all-board, t, is placed centrally in/front of each rib, parallel thereto, with its tace toward the same, the ends thereof being secured in the transverse partitions ofthe reel, as shown in iis. 1.

The outer side or face of cach fall-board t, faeing its appropriate rib a., is made slightly convex in transverse section, as illustrated in fw. 2, so' that the flour', thrown inwardly from the bolting-cloth, in the revolutions of the reel, is caught 0n the rib and thrown out again at such an inclination to the face of tating thereby its sifting.

The ilour, entering the bolt through the feed-aperture f in the cap F, passes through the cylindrical sieve G, and, being 'distributed over the 'headplate B", passes through the-concentric apertures E, E therein, against the bolting-cloth ot' the rst compartment ofthe reel A.

As the reel revolves, thc tlonr passing over the edges of the ribs a c is thrown against the strips or tall-boards, 4t t, and thence back again upon the cloth, and, as it-is carried forward, because ofthe inclination of the reel, is caught against strips 1t R, secured radially against ,the upper face of each partition C (and of the lower head B,) in register with the vanes lr lr of the cones P, and thus led down upon the conical flaring surface of the cone at the central opening min the partit-ion, and over the surface of the cone on through said opening into over the reel by centrifugal force.

The bugs, the., caught in the entrance-sieve G are thrown out by centrifugal force through the channels t' i in the head, and, by means of this sieve, in combination with the outer cap F and cylindrical casing 1), the entrance of bugs and vermin into the bolt is etfectually prevented. v

The outer cylinderserves also as a protection for the cloth against accidental or mischievous thrusts or injury from without.

The lower opening m' is guarded by means of its conical valve P', by which it may be completely closed.

I claim as my inventionl. The combination of two or more transverse eentrally-perforated orV annular partitions C O, with the intcrion of a bolt-ing-reel, A, to retard the passage of (leur through the same, substantially as herein set forth.`

2. The combination of thc conical flaring valves l. P, with the ccnt'al openings m, in the transverse partitions C C, and the lower' head-plate B of a sectional bolting-reeh-,to close and conti-oi saidopenings, substantially as herein set forth.y l

3. 'lhe concentric apertures or feed-ways E E, formed in the head-plate B'of a tlour-bolting reel, for distributing the flour delivered within thereel upon and against the boltiinf-cloth covering the same, substantially as herein set forth. j

.4. The combination of a conical cap, l", protected' by a sieve, G, with the concentric feeding-'apertm'es E E, in the head B' of the reel A, substantially as herein set forth. 4

5. Thelongitudinal strips or fall-boards, t t,'com

The lower journal N is pierced longitudinally withV the cloth as to cause it to slide over the same, facilithe next compartment, where it is again distributed bined with the ribs a a of a halting-reel, substantially as and for the purpose herein set'forth.

6. Radial guide-strips R R, )rejecting from the upperV side of euch partition C, und the lower head B of a sectional boltingreel, in combination with flaringA valves or cones P P, suspended over or against the central openings mi, in said partitions and head, substantially as herein set forth.

7. The combination, substantially us herein described, of a. hollow journalmrm N, secured to und ,lows

supporting the lower head B, of a. sectional boltingreel, the rod Q connecting and controlling the valves closing the apertures m in its interior partitions C, and the'jouriml-mm` N secured to the upper end of the reel.
