J OHN H. \VALSH, OF MASON CITY, IOIVA.
ROTARY BOLT.
SPECIFICATION forming part of Letters Patent No. 398,478, dated February 26, 1889.
Application filed April 2 5, 1 8 S 7.
To all whom it may concern.-
Be it known that 1, JOHN H. \VALsH, a citizen of the United States, residing at Mason City, in the county of Cerro Gordo and State of Iowa, have invented certain new and useful Improvements in Flour-Dressers, of which the following is a specification.
This invention relates to flour-dressing machinery of the class commonly known as fioun bolts and my object is to so improve the construction of such machine as to secure a more perfect and economical bolting of the flour, and by means comparatively cheap and simple.
The invention consists in the novel construetion and combination of parts hereinatter described, andpointed out in the claims.
In the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a machine embodying my invention with a portion of the upper part removed, showing the interior arrangement of the reel and connected apparatus; Fig. 2, an end View of the same, but with a modified form of actuating mechanism; Fig. 3, a similar View of Fig. 1, the outer head or disk of the frame being removed and portions of the internal gear of the cylinder-ring broken away to show the arrangement of the pa] ts inside; Fig. i, a fragmentary view of a modification in the construction of the reel and connected parts, showing also an intermediate stay-ring and the adjustment of the same; Fig. 5, detail of the chain-belt connection with the elevators; Fig. 6, an elevation of the conveyer and its immediate connections from the side nearest the bolting-cloth; Fig. 7, a transverse sectional view looking toward the tail of the machine, and Fig. 8 a fragmentary view showing the attachment of the bolting-cloth to its end ring in detail.
Similar letters of reference indicate corresponding parts.
The frame A is in the main similar to those in common use and need not be particularly described. To each end of this frame is at tached a head or disk, 13, by means of suitable.
lugs or flanges, 13 B. An annular flange, 1),
[ are fitted to the annular flange of the head B and may be arranged to turn inside or outside of said flange, as shown in Figs. 1 and 4. The rings are actuated by suitable gearing, and for this purpose are provided. with internal or external gear-teeth, as may be desired. In practice I prefer to use an internal gear on the ring, because a single pinion meshing with it revolves the cylinder in the proper direction, whereas in the case of external gearing the number of wheels must be increased, as shown in Fig. 2.
In suitable boxes, a a, which may be permanently or adj u stably attached to the heads B B, are mounted shafts E E E l5, which extend through the entire length of the reel. 5 To one of these shaftspreferably li1-is secured a pinion, F, which, meshing with the internal gear of the ring 0, actuates the same as the shaft is revolved by the pulley G. \Vithin the reel and a short distance back from the end rings sprocketwheels' I I I are mounted on the shafts E E and carry chain belts J J. .lln'ough that are of the circle intersecting he periphery of the sprocket-wheels nearest the bolt-cloth the chain belts are distended to the same rela' tive curve as the adjacent inside of the c vl inder by means of guides c, secured to the inner face of the heads l3 13. The friction of the chain belts on the face oi. these guides is relieved by the intermediate travelers, I. At suitable distances alon these chain belts are attached elevators II ii, which are in the nature of troughs, as shown, and extend the .whole length of the interior bciting-surface of the reel. The elevators are set about half an inch from the bolt-cloth through a considerable part of their circuit, as shown, and as the reel revolves in the direction indicatedby the arrows gather up the stock in the bottom y direction, depositing it gradually along the j inner surface of the bolt-cloth (7. Any stock that may remain in the elevatcn's after passing above the horizontal center of the reel is carried over and deposited in the trough of the conveyer L, to be moved farther toward. the tail of the machine and, as worked out of the conveyer-trough, carried around with the reel until thoroughly bolted.
It is desirable that the elevators should IOO move with. the same speed as the boltcloth, so that the bolting may be as gentle as possible, and neither hastened nor retarded by the action of the elevators beyond the natural ea- 5 pacity of the bolt-cloth to iiroperly sift the flour. To secure this result in the case of the construction shown in Figs. 1 and 3 requires that the pinion. F should be somewhat smaller than the sproeketwheels I I I, the exact relative size of the wheels and gearing being determimible by careful mathematical calculation but where, as in the case of the construction shown in Fig. 2 intermediate gearing is used to actuate thereel the size of the pinion is not very material, the proper speed being easily secured by the comparative size of the intern'iediate gears, c 6'. Of course these gears may mesh directly or be connected by chain belt, provision being made for the corresponding change in the direction of their revolution.
The bolt-cloth d is attached. to wooden or metallic rings ff, secured by screws or bolts to the rings 0 In practice I attach the canvas, (7, or other like suitable material, is sewed to each end of the bolt-cloth and provided with button-holes. The interior or periphery of the ring, as the ease maybe,is provided with a series of studs or buttons, i i, and the canvas end of the cloth is brought around the ring and buttoned thereon. By means of set-screws 7t 71 the bolt-cloth may then be stretched to any desired extent. One or two rings may be used at each end, as shown. Where two are used, as shown in Fig. 'l,the outer ring is of course not drawn tightly to its place until the cloth is stretched by the inner one.
The middle portion of the reel is made perfectly true by the use of one or more stayrings, g, the periphery of which is faced with felt or the like and the inside turned perfectly true. The bolt-cloth is sewed to this felt, and the position of the ring is adjusted by the setscrews 7c in the rods D D. On one or more of the shafts carrying the sprocket-wheelspreferably the upper and lower onestravelers M are loosely mounted, and, following this ring, serve to support and steady the middle of the reel.
The flour-conveyor L is mounted within and at the descending side of the reel, and revolves in a direction opposite thereto, working the flour over the outward edge of the trough N and toward the tail of the ma-' chine, which is at the left in Fig. 1 and at the right in Fig. U. The stock is admitted to the conveyer by and through the inlet-spout R, Fig. (5, flows over the edge of the conveyer-trough in a thin sheet, and falls be tween the bolt-cloth and an. apron, O, corresponding i ractically to the curvature of the reel and extending from the edge of the trough. to nearthe bottom of the reel. As before stated, the unbolted portions of the stock are carried over by the elevators and bolt cloth in the following manner: Strong redepositediu the conveyor, where the action of the conveyor-Iiights tends to break up any balls or lumps that may have accumulated, especially in the case of moist flour. The middlings'pass out through the tail-spout s. This and other features of the invention already described render it of special value in the matter of rebolting where the first process has been imperfect.
The flow of the stock toward the tail of the machine is regulated by the relative height and inclination of the outer edge of the trough N; At the head of the machine this should be high enough to p revent the stock being thrown over the edge until some distance from the head, and for this reason the outer edge of the trough is quite sharply inclined here, as shown in Fig. 1. For the remainder of the operative length of the trough the incline may be very gradual, or the edge of the trough may be made quite horizontal, as may be found desirable. This part of the machine may be made adjustable by making that partof the trough that serves for the outer edge of a separate piece suitably bolted to the trough itself.
Above the conveyer is mounted a revolving brush, P, mounted in the same manner as the shafts before referred to. This should revolve in the opposite direction from the reel, and serves to clear the bolt-cloth of adhering flour. 'ly an adjustment of its journals its distance from the bolt-cloth may be regulated.
A simple manner of attaching the elevators to the chain belt is shown in Fig. 5. The linkl is of a common form, having lateral lugs to receive a pin, on. To the under side of the elevator K is attached a lug, n, engaging with those of the link. The elevator is prevented from turning on the link by the projections-o 0, resting on the top of said link.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a flour-dresser, the combination of a cylinder or reel, substantially as described, stationary heads upon which the reel revol ves, shafts mounted in said heads and provided with sprocket-wheels, chain belts carried by said sprocket-wheels, elevators mounted on said chain belt within said reel, and mechanism, substantially as described, adapted to rotate the reel and carry said elevators in. proximity to a portion of its interior, substantially as and for the purpose set forth.
