FLOURnBOLT.

SPECIFICATION forming part of Letters Patent No. 310,572, dated January 13, 1885.

(No model.)

Z'o LZZ whom, it may concern:

Be it known that I, Jarras C. Fanzine, a citizen ofthe United States, residing at Vassar, in the county of Tuscola and State of Michigan, have invented certain new and useful Improvements in Flour-Bolts, of which the following is a specification,reference being had therein to the accompanying drawings.

Figure l is a longitudinal section of a centrilugal reel containing my invention. Fig. 2 is an end elevation ot' the same, portions of the casing being broken away. Fig. 3 is a vertical section on line w fr, Fig. l. Fig. et is a vertical section showing the invention applied to an ordinary form of bolting-rcel. Fig. 5 is an elevation of the head end or receiving end of the bolt shown in Fig. 4.

Similar letters of reference indicate like parts in all the iigures.

The frame and casing may be of any usual `or approved construction, in which A is the head end, A the top or deck, and A2 the casing at the tailA end of the machine.

A A. are vertical partitions arranged at both ends a short distance inside of the easing, and provided with circular openings to Ieceive llanges of the reel-heads, as will be hereinafter explained.

The upper conveyer-box, in which the conveyer B works, has its tail end constructed of a downwardly-extendcd portion, c, of the partition A at that end ol' the machine, the end b at the head end of the conveyer-box consisting of a separate part arranged farther from the front end ot' the casing and upon the opposite side of a crossgirt, A", from that to which the l'ront partition, A", is attached. The bottom ol' this conveyer-boX, as well as the bottom of the conveyer-box C, is provided with a number of cut-offs, (marked, respectively, b c.)

D is the central beater-shaft.

E E are the spokes or arms, each set rotating from a central hub, which is keyed to the beater-shaft.

F F are the beaters, which may be mounted upon spider-arms E, `or disks attached to the beater-shaft.

G G is the feed spout or hopper, the horizontal extension Gf of which is, by preference, circular in cross-section.

d is a worm attached to the beater-shaft D,

and operating to discharge material from the hopper into the interior of the reel.

H is a distributing-plate mounted upon the beater-shaft a short distance from the inner end of the horizontal part G of the hopper.

I l l2 are the reel-heads, each having a central opening with a flange or shoulder, t', another llange, shoulder, or rib, fi', of greater diameter, and an inner iange, shoulder, or rib, 2, of less diameter, all of these flanges or shoulders being circular, the inner one fitting closely the outer opening in the partition AJ.

J J are frictional supporting and driving rollers keyed to a sha-ft, J, in such position as to engage with the outer faces of the flanges jj are anti-friction guiding-rollers arranged upon opposite sides ofeach head. rllhese guiding-rollers are mounted upon the inner ends of shafts y" j, and are keyed thereto, the shafts rotating in boxes or bearings a a. (See Fig. 2.)

K is a bevel-pinion keyed to the projecting end of the beater-shaft, and meshing with a `bevel-wheel, K', mounted on the upper end of upright shaft Ft.

K3 is a friction driving-wheel, the hub of which is grooved to receive the arms it', which project horizontally from a vertical plate, 702, which is secured to a vertical post, A5, of the frame-work by means of bolts a2, which pass through a vertical slot, a, of such length as will permit the friction driving-wheel K3 to be let down from the position shown in Fig. l so far that it will engage with the opposite or lower side of its engaging wheel J2.

At the opposite end of shaft J is a setscrew, J 2, mounted in a cross-girt or other suitable support, with its inner end bearing against the end of said shaft in such manner that by turning the screw in the proper direction the driving-wheel J2 can be caused to impinge upon the wheel K3 with such force a-s to rotate the reel. By preference, I insert a steel spindle, J3, in the socket in the end of shaft J to receive the thrust of the set-screw; but this spindle may be omitted.

From the above description it will be understood that by properly shifting the position of the friction driving-wheel K3 the'speed of the rotation of the reel can be varied, as can the direction of its rotation.

C2 C3 represent bevel-gears mounted upon IOO the vertical shaft Iv2 and the conveyor-shaft for driving the conveyers.

Motion is communicated to the beater-shaft by belting its pulley D2 to any suitable motor which will drive the beaters in the direction indicated by arrow 2, Fig. 2.

L L represent longitudinal bars or ribs attached'at their ends to the outer flanges or ribs, t fi', of the reel-heads.

In Figs. 1, 2, 3 the outer face of the reel is many-sided, as at M M, having longitudinal bars L L and hoops, as indicated at N, Figs. 1 and 3.

O is a brush extending longitudinally of the reel, its central core or base being journaled at its ends and supported upon vibrating arms o. (See Figs. 1 and 3.) These links may be either pivoted to some portion of the framework or casing of the bolt, or they may be hung upon a shaft, I), which extends the entire length ofthe machine, and is mounted at its ends in the partitions A" Ad, as shown in Fig. 1.

In operating this reel or bolt the material which is fed in by the Worm d is caught by the rotating, corrugated, or ribbed plate II and properly distributed to the beaters F at thel head end of the reel.

Vhen desired, an opening maybe made in the feed-spout of hopper G, with a slide or other cover, for the admission of air in suitable quantities.

In Fig. et the invention is shown applied to an ordinary bolting-reel, in which Q is the central shaft. q q are the spokes or arms, carrying the longitudinal bars of a many-sided reel. The shaft Q, is, by preference, provided with an ordinary Wing-gudgeon, the shank or journal 1- of which is mounted in a suitable bearing on the frame, and carries at its outer end a i'rictioirwheel, J, there being by preference at the opposite end of the shaft setscreW j, for forcing the wheel J against the friction driving-wheel K", which is mounted upon a vertical shaft, K2, driven from any desired motor. The hub of this friction driving- Wheel is grooved and mounted in a sliding bearing in substantially the same manner as is the corresponding driving-wheel and bearing in Fig. 1, and hence need not be specifically described.

Although I have shown in Fig. et but two bolts arranged in a chest, one above the other, it is evident that any desired number might be similarly arranged and driven in the same manner. It will of course be understood, particularly When the axis of the reel is inclined, that by turning the screw j" backward the engagement of the Wheel Ji With the friction driving-Wheel K3 may be relieved so that the reel Will cease to rotate, and thus any one or all of the reels may be permitted to stand still without interfering with the continuous rotation of shaft K2.

I am aware that friction-gearing has been used for driving grain-scourers in which the operative parts have rotary motion, and do not claim such construction; but it is evident that many advantages arise from the construe tion which I have shown in both styles of boltsto wit, a horizontal driving-shaft projecting through the casing of the bolt-chest, with a wheel mounted on the projecting end of the' shaft to rotate in a vertical plane, in combination with ay driving friction-Wheel mounted upon avertical shaft and rotating in a horizontal plane-because, among other things, such construction makes it possible to shift the driving-wheel to points both above and below the center of the driven Wheel, and thus change the direction of rotation of the reel.

Ido notin this case claim anything except what is specifically set forth in the claims hereof, reserving to myself the right to claim all other matter not therein set forth but shown in the drawing or described in the specifica tion in another application which I am preparing to file.

That I claim is- A 1. In a flour-bolt, the combination of ahorizontal reel, an inclosing-casing, a horizontal shaft, one end of which projects in front of the end of the casing, a driven friction-Wheel mounted upon the projecting end of the h`orizontal shaft, and a friction drivingwheel rotating in a plane at right angles to the plane of the driven wheel and engaging with the driven wheel, substantially as set forth.

2. In a ilour-bolt, the combination of a horizontal reel, an inclosing-casing, a horizontalshaft, one end of which projects in front of the end of the casing, a driven friction-wheel mounted on the horizontal shaft and rotating in a vertical plane, and an adjustable friction driving-Wheel rotating in a plane at right angles to the'plane of the driven wheel and engaging with the driven wheel, .substantially as set forth.

3. In a flour-bolt, the combination, with a horizontal shaft, one end of which projects in front of theinclosing-casin g, of a slotted standard at right angles to the horizontal shaft,and a friction driving-Wheel mounted on the slotted standard and adjustable relatively to the driven wheel, substantially as set forth.

4:. In a flour-bolt, the combination, with the horizontal shaft, oneend of which projects in front of the casing, of a driven friction-Wheel mounted on the projecting end of the horizontal shaft, and a friction drivingwheel mounted on an axle at right angles to the horizontal shaft, and adjustable on a line at right angles to the horizontal shaft, substantially as set forth.

5. rIhe combination, in a our-bolt, of the beater-shaft, the vertical shaft driven by the beatershaft, the friction driving-Wheel rotated by the vertical shaft, the supporting and driving wheels mounted on a horizontal shaft, and the vertical wheel mounted upon said shaft and engaging with the friction driving-Wheel, substantially as set forth.

(5. In a Hour-bolt, the combination, with IOO IIO
