FLOUR-BOLT.

SPECIFICATION forming part of Letters Patent No. 391,281, dated October 16, 1888.

Application filed .Tune 25, i337.

To all whom it may concern:

Be it known that I, CnarsTrAN N. SMITH, a citizen ofthe United States, residing at Dayton, in the county of Montgomery and State of Ohio,'have invented certain new and useful Improvements in Flour-Bolts; and I do declare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specication.

Figure l of the drawings is a side elevation of my improved bolt with the outer casing removed and the boltingcloth J broken away. Fig. 2 is a broken vertical longitudinal section of both ends ofthe bolt. Fig. 3 is a front end View with outer casing partly broken away. Fig. 4 is a transverse section on line rv x, Fig. l. Fig. 5 is a rear end View; Fig. 6, a detail perspective view of bolting-cloth J.

The invention relates to improvements in Hour-bolts, the object being to bolt on a continuously-moving inclined plane; and it consists in the construction and novel combination of parts, as hereinafter set forth.

Referring to the drawings by letter, A designates theV frame of the machine, including the casing and the legs or supports upon which the latter rests. The actuating-shaft B isjournaled at the end that carries the pulley in the side of the casing and at the opposite end ina boss on the end plate of the feed-conveyer casing or cylinder O, having the fced-openings c at its upper and outer end. The feed-eonveyer screw D is secured to a sleeve, d, secured to and turning with the shaft B within the casing or cylinder O.

E E are sprocket or pin wheels, preferably the latter, one secured to the shaft B inside one end of the casing and the other provided with a hollow hub, c, that rides on the feedcylinder and is connected by radial arms with a smaller hub, e', secured to the shaft inside of the inner side of said cylinder.

F is an end board, upon the concave upper edge of which the hub c rests and turns, and with its edges converging downward. The end board has secured to its outer side, at the edges thereof, the stripsf,wl1ich have secured Serial No. 942,409. (No model.)

l between their upper ends a transverse board aiding in the support of the feed-conveyer cylinder.

G is a wheel below the corresponding pinwheel E, and journaled on a pin, g, secured to a slotted plate, H, rendered adjustable on a piece, h, fixed between the lower ends ol' the stripsf by means of the set-screws h', asshown in Fig. 2. The said pin moves in a slotin the piece 7L, and when adjusted by the screws It is set or held by the screw h2, which passes through the upper edge of the piece h. The wheels E and G are connectediby the band I, provided with the metal eyelets fi, that register with the pins on the upper wheels. At the opposite end ofthe reel there are similar upper and lower wheels to those described, bearing similar letters, the upper wheel having been described, and the lower wheel being adjustable and set by similar parts bearing similar letters. There is no end board at this side which is open, except so far as itis closed by parts hereinafter described.

The two eyelet-strips I have their inner ends secured to the bolting-cloth J, which has its ends formed by said straps and has its form re tained between the straps by the spring-bands K, which partake of the general shape imparted to the cloth by the wheels E G and lie against the inner surface of the cloth in eircumferential pockets forlned thereon by cloth or other suitable material, the pockets being stitched at both edges to the cloth to retain the spring-bands in place.

L and M are respectively longitudinal eX- terior and interior strips, which are arranged in equidistant pairs, the members of each pair being opposite and bolted together. The strips aid in keeping the bolting-cloth in its proper form.

Nis a wide longitudinal board running withinthe bolt, with its ends secured to proper points of the framework thereof. Standing inward from said board N are the equidistant guideboards O, which have their outer edges pivoted about centrally to the board N and their inner edges free. These boards incline downward at such an angle that the upper edge of any one is about or a little more than vertically above thelower edge of the adjacent one toward the feeding end ofthe machine. The

IOO

of the said handle the guide-boards O can4 have theirinclinations changed to suit'the rate of speed required by the operator.

Vhen the material is fed into the feeding cylinder, it is conveyed thence through the open inner end of said cylinder within the bolt and falls upon the rear surface of the boltingcloth, which is inclined upwardly and rearwardly by means of the curved arms P upon a longitudinal shaft, p, pivoted in the ends of the frame and actuated by a suitable handle on its outer end. The said arms P bear against the rear edges of the end portions of the reel proper. The shaft p has upon it a ratchetwheel, Q, which is engaged by a pawl, q, pivoted on the main frame, so that the bolt can be held at any desired inclination within certain limits. The flour rst falls upon the adjacent lower inclined part of the bolting-eloth, which is moved continuously upward by the described mechanism and is moved upward therewith, the interior strips, M, acting somewhat as buckets. Vhen on the upper turn of the cloth, it falls therefrom upon the adjacent guideboard O, down which it slides to the bottom of the bolt a certain distance nearer the discharge end thereof. It is then again elevated, as before, and falls on a second board O. It progresses thus toward the discharge end of the bolt, the fine our passing through the bolt-cloth and,falling upon the inclined sides R R of the casing, is delivered thereby into the conveyers S, of ordinary construction. All else than the bolted flour passes out through the discharge-chute T, lying against the last rear guide-board O. It is found in practice that the spring-bands here` tofore described are rendered necessary to keep the bolting-eloth in proper forni.A Before the flour passes to the conveyer it falls on the guide-blocks T rI", which are triangular in cross-section and have their inclined sides upward. By means of the said blocks the Hour may be delivered entirely on one side in any desired quantity.

The lower Wheels, G, are notprovided with pins, as they will turn better without the same.

'Ihe board N, to which the deectors O are pivoted, is secured in a stationary manner to the frame, and as the bolt swings on the shaft B and is held at any angle by the ratchetwheel Q and pawl q it will be seen that by throwing the bolt to the left the face or edges of the deflectors will come in contact with the longitudinal strips M, which act as buckets.

Having described my invention, I claiml. In a tlour-bolt, the combination of wheels E and G, bolting-cloth J, provided with pockets and having its ends supported by said wheels, the circumferential sp rings K,secnred within said pockets, and means for imparting motion to wheels E, and through them to the cloth, substantially as specified.

2. In a flour-bolt, the combination, with the main frame, the Wheels E and G, and the boltingcloth provided with pockets, of the shaft p, journaled in the main frame the arms P and ratchet-wheel Q,seeured to said shaft, and the pawl q, pivoted on the frame for the pur pose of holding the bolt at the inclination to which it has been turned by the arms, substantially as specified.

3. In a flour-bolt, the combination, with the bolting-eloth having the straps secured to the ends thereof, provided with eyelets, and the pin-wheels on the main shaft, of the wheels G, `)'ournaled on Athe pins g, the adjustable slotted plates H, the pieces h, and set-screws h', substantially as specified.

4. In a-i'our-bolt, the combination of wheels E and G, bolting-cloth J, provided with pockets and having its ends supported by said wheels,the circumferential springs K, secured within said pockets, the longitudinal interior and exterior strips bolted together, and means for imparting motion to wheels E and through them to the cloth, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHRISTIAN N. SMITH.
