CENTRIFUGAL REEL.

:ZPECIFICATION forming part ofLetters Patent No. 326,509, dated September 15, 1885.

Application filed June 25, 1855.

To all whom it may concern.-

Be it known that I, BRUNO KNIFFLER, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented new and useful Improvements in Centrifugal Reels; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvementsin the class of flour-dressing machines usually known as flour-bolts and the invention consists in the construction, arrangement, and combination of various parts, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure 1 is a perspective view of my improved machine, showing the rear end thereof. Fig. 2 is a perspective view of the front end. V Fig. 3 is a horizontal section on the axis of the shaft of the bolting-reel. Fig. 4 is a vertical central cross-section. Fig. 5 is a horizontal section on line 3/ y in Fig. 4. Fig. 6 is adetached view of the driving-gear and clutch. Fig. 7 is a detached perspective of front and rear of the head which forms the rear end of the bolting-reel. Fig. 8 is a detail on an enlarged scale. I

. A is the main shaft, running horizontally through the center of the machine, and pro: jecting beyond both ends of the same; and B is the drive-pulley,secured to either end of the shaft. This shaft is journaled in suitable boxes, to I), supported by the frame of the machine, and has secured to it the heater-frame O, which is of known construction and operation.

D and E are the heads of the reel-cylinder; and F is the bolting-cloth, secured to the periphery of these heads and supported between them, so as to form the usual bolting-reel.

In the drawings the bolting-cloth is supported between theheads in the following manner: A cylindrical cage is formed between the two heads by a series of stays, h, to which, at suitable distances apart, the clampsz' are secured, so as to form radial supports for the hoops j, which are secured thereto. The bolting-cloth is made of the proper cylindrical shape to fit over the cage, and is secured at its ends in any suitable manner to the heads and (No model.)

also to the loose ring 70, by means of which and the bolts lit is drawn tight in the usual manner.

The front head, D, is provided with a hollow hub, c, which is journaled in the boX d, and the rear head, E, has a hollow hub, e, which is sleeved upon the shaft A and journaled in a box, f.

G is the spout-box, to which the lower end of the feed-spout is secured. It communicates with the hollow hub c of the head D, and a screw-conveyer, H, secured upon the shaft A,

conveys the feed from the spout through the hollow hub into the reel after forcingitthrough 6 5 the wire screen I, which is secured over the discharge opening.

The spout-box G is adjustably secured to the box d by means of bolts m, passing through circular slots n, (seen better in Fig. 8,) so arranged that the spout-box may be adjusted to receive the feedingspout at any angle that may be most convenient.

The driving-gear is arranged as follows: To the free end of the hub e of the head E is secured a gear-wheel, o, and a pinion, p, is secured to the main shaft A. Upon a countershaft, 1', below the main shaft are sleeved the gear-wheels q s, the former engaging with the pinion p,and the latter with the gear-wheel 0. To each of the gear-wheels q s is secured one member of a clutch, J, and a lever, K, is arranged to open or close' the clutch by sliding the gear-wheel q laterally upon its shaft.

A locking devicesuch as the pin t, engaging into suitable holesis arranged to lock the lever K into position to hold the clutch J closed or opened, as desired.

L is a sprocket wheel secured upon the counter-shaft r, and M and N are sprocketwheels secured upon the ends of the shafts of the conveyers O O, which latter are arranged under the reel in the usual manner. An endless chain, P, passes around the sprocket wheels and conveys motion to the conveyers.

Q is a brush secured at the top of the machine for the purpose of keeping the meshes of the cloth open by being broughtin contact therewith when desired.

A system of cut-offs is arranged below the reel in the following manner: At the lower end of the case, where it discharges into the conveyer-boxes, aseries of slides, R, are arranged alongthe two sides of the case, cleats at being secured to the cant-boards between the slides to hold the latter in position and guide them in opening or closing them. All the slides may be closed or opened independently of each other, so that all or any desired portion of each conveyer may be cut off from access.

The rear head, E, of the reel is provided upon its inner side with pockets S, into which the tailings are scooped by means of the scoops T, and from which the tailings are discharged through the openings 1: into the dischargespout U. The scoops T are adjustably secured, so that their free ends may be brought nearer to or farther from the periphery of the head; I preferably provide, to this end, the scoops with threaded bolts w, which are secured to'the scoops and project through radial slots at in the head. By means of-thumbnuts z, secured upon the threaded bolts, the

scoops may then be, adjusted radially inor out from the outside, an indicator-scale being provided alongside the slots for the proper guid ance of the operator.

The. caseoflthe machineis of the usual description, but is preferably built in sections,

. so as to be readily taken apartfor the purpose of giving ready access to all the parts to facilitate changes or repairs.

The operation of the machine does not diifer from others of its kind;. but it'presents the following advantages: @First. The adjustable spout-box provides betterfacilities for connecting it with the feed-spout by allowing it to be directly connected therewith at any angle.

. Second. The system of cut-ofi is simple and perfect, as the material can be-cut off from one conveyer to the other at any point desired, the. adjustment of l the cut-ofls being eifectedinstantaneously by raising the hinged .cover of the conveyor-box at either side of Third. The outside bolting-cylinder can be stopped at any time without throwing off the belt. 'Should it become necessary to stop it -for the purpose of repairing the cloth, to regulate. the discharge of thetailings, or for any. other purpose, it is only necessary to throw the clutch out of gear by means of the lever K. .When it is considered that the:operation of the machine is thus not materially interfered with, and no general stoppage of other mill machinery need occur on this acr .count, the advantage of this improvement will readily appear.

, Fourth. The wire screen in the, front head of the reel. forms an effective disintegrator, which thoroughly loosens the material to be bolted as it passes into the reel.

Fifth. The device for regulating the discharge of the tailings forms also an important feature, whereby the material can be retained in the reel any length of time found necessary.

Its adjustment to any degree of nicety is simple and easily eifectediwhile the machine is in operation by first stopping the outside cylinder by means of the lever K, and then raising the sliding panel at the tail end of the machine, which gives access to the regulating devices which adj ustably secure the scoops. By loosening the thumb-screws and moving the bolts in the slots provided for them the scoops can bernoved from orto thefcloth, care being taken to adjust'them all alike by means of the index. I l
