SPECIFICATION forming part of Letters Patent No. 274,234, dated March 20, 1883.

Application filed November 3, 1882. (No model.)

To all whom it may concern:

Be it known that I, J onN J WALTEEHoUsE, of `Vincennes, in the 'county of Knox and State `of Indiana, have invented certain Improvements `in Centrifugal Reels, of `which the `following is a specification. p

My invention relates to that class of machines employed in milling commonly known as centrifugal reels 5 and it consists in various features hereinafter explained.

In theaccompanyin gdrawin gs, Figurel represents a longitudinal central section through my improved machine; Fig. 2, avertical transverse section of the same 5 Fig. 3, an end view of the reel-head 5 Fig. 4, a side elevation of the same; Fig. 5, a side or face elevation of the beater-cylinder with afew of the blades or flights in. position Figs. 6`and 7, plan and end views of the hanger or bracket which carries orsupports one end of the beater-shaft.

The general principle and Inodey of operation `of my machine are essentially the same as in other machines of this class-that is to say, the material enters a reel or cylinder covered with boltingcloth or screening material and arranged to revolve slowly, the liner Inaterial being caused to pass through the meshes of the reel cloth or clothing by the action of a rapidly-rotating internal beater or fan-like cylinder, the oifal or coarsermatters passing off at the tail of the reel.

My improvements are designed to render the machine more perfect in its action, to simplify its construction, and to enable the operator to keep it always in perfect working condition without diiiiculty or inconvenience.

i. With these objects in view I construct my 5o other in its rotation.

machine as represented in the drawings, in which- A represents a stout frame, ordinarily made of wood B, the reel or` cylinder arranged in said frame; and C, the beater, likewise mounted in the frame and arranged within the reel, as shown. The reel or cylinderB is provided with tubular journals a b of sufficient size to permit the shaft D of beater U to pass freely through them without actual contact, so that there shall be no friction of one upon the other and no tendency of one to be influenced by the The journal b is made of greater diameter than journal a, in order Y that room may be afforded for a spiral feeding l blade or worm, o, secured upon the shaft D and passing through the journal b into the feed-box d, which is fixed to the framing A. The journals a and b are mounted in laterallyadjustable boxes or bearin gs E, which rest and are arranged to slide a limited distance upon supporting frames or"` brackets F G at opposite ends of frame A, set -screws eand jamnuts f being` provided to effect and maintain the adjustment of the journals of the reel. In like manner the ends of shaftD are carried in laterally-adjustable boxes or bearings H, also arranged to slide a short distance upon the supporting frames or brackets F G, and like- Wise provided with adjusting-.screws g and jam-nuts l1.. By means of the adjustable boxes or bearings E and H the shaft D may be accurately centered in the tubular journals a b of the reel, and consequently the beater will be exactly centered in the reel-a feature ot great importanceand very essential to the success ot' this class of machines..

lThe beater C is composed of the central shaft, D, a series of spider heads or frames, I,

and a series of` longitudinal blades orflights, '5, secured to the annular rims of the spiderframes, as more plainly seen in Fig. 5.

Heretofore the blades have been made of one continuous strip each, involving the necessity of an entire new blade in case of injury, and also requiringV long and comparatively expensive strips of material in the iirst instance. I however employ at suitable intervals heads having wide flanges or ears to permit the at tachment to one head of the ends of independent blade-sections, thus permitting shorter sections to be used.

The heads or spider-frames are made adjustable upon the shaft, being held by setscrews j, or equivalent means, so that they may be rotated upon or moved lengthwise of the shaft, as desired. This facility of adjustment permits the heads or spider-frames to be set diierently upon their shaft, and allows the blades to be set at any desired angle to the shaft. It also permits one blade-section to be set at a greater or less angle or inclination relatively to the shaft D than another section,

thus enabling the builder or the operator to` IOC) ' in its length, as may be required or advantageous with different grades of bolting-cloth v commonly used ondierent portions of the reel or cylinder, or bydierent conditions of the material in different parts of the reel It will be seen that even with continuous blades or ights some variation in the inclination can be readily made.

It is desirable that the ends of the separate sections should abut against one another adAA form in effect a continuous blade, for the ieason that any open space between the ends will cause eddies and currents of air that will in some degree interfere with the perfect separation ofthe material into distinct grades. While, 1 therefore, the machine will be operative, yeven if the blade-sections do not abut, it is prefer- Vable to have them do so.

The bolting reel or cylinder consists of two heads, J K, each formed or furnished with a tubular shaft, lettered respectively'a. and b, as above mentioned, said 7heads being connected and tied together by longitudinal ribs or rods k, bolted or screwed tothe heads, as shown in Fig. 1. The head J is encircled by an annular band, L, formed with an inwardly-projecting radial flange, or lugs, l, which overhang the head, as showninFig.1. This band fits snugly around the head J, but is free to slide or move thereon in the direction of the length of the reel; and for the purpose of moving it outward or away from the head, cams or circular wedges M are yjournaled upon the head J by central pivot bolts or screws, Im, so that by rotating said ycams or wedges the hand L will be drawn outward. j

In order to provide for the more convenient turning of the cams, and for the gradual vand accurate adjustment thereof, their peripheries are toothed and caused to mesh with small pin-l ions n, each turning upon a stud or center pin, o, fast to the head J. The pinions are each furnished with a squared head or neck, p, to

. receive awrench or other tool by which to turn them. i N N represent two exible bands, prefer- Y ably of hoop-iron or like material, one encircling the head K and the other encircling the band L, and each formed or provided with ears q near its end, and with a right-and-left screw-stem, u, screwing into said ears and serving to draw them together, the middle portion ofthe stem being squared for convenience in turning. These bands are for the purpose of clamping and holdin gthe bolting-cloth upon the reel at the ends, and, if necessary, similar bands may be applied at intermediate points in the length of the reel, being placed directly around the inner stiening ribs or hoops r. Ordinarily, however, the bands will be used only at the ends, and theintermediate portion of the reel-clothing, being left free,can be drawn tight by the rotation of the cams M and the consequent outward movement of ring or band L, and with it the band N thereon. ,Ifintermediate retaining-bandsNbe employed,

they should be loosened when the cloth is to be tightened. The cloth may be laced along the seam or otherwise secured, as found expedient..

The bod y of the machineis boarded or closed, as usual, and beneath the reel or bolting-cylinder the sides lof the chest are inclined toward each other, as more plainly seen in Fig. 2. The inclined sides are composed of or provided with numerous slides or movable boards, O, each capable of being raised and lowered independently of the others. line of meeting vof the two inclined sides or series of boards O is placed a vertical board, P, which forms a partition between two conveyertroughs, Q, each furnished with a conveyer, R. By opening a part of the slides on one side and another portion, not opposite tothe first, on the opposite side, itwill be seen that the material will fall partiallyinto one trough and partially into Lthe other. regulated by opening or closing the slides O, so as to cause material of one ygrade to pass wholly into one trough and that of another or different grade to pass to the other trough,

Directly beneath the The point of division may be whence they maybe delivered to different points. j

For the purpose of imparting motion to the apparatus, I secure upon the shaft D a driving-pulley, S, which receives motion from any prime niotor by belt. Said. shaft is further provided with a belt or chain wheel, T, from which motion is transmitted through a belt or chain, s, to a larger wheel, U, on one of the conveyer-shafts R. A second wheel, V, on

IOO

said shaft gives motionto the reel orn cylinder B through a belt or chain, W, and a wheel,X,.

secured upon the reel-journala, as shown. The second conveyer may be turned by a belt from shaft D, or by belt or gear from the first conveyer-shaft.

In order to bring the wheels V and X close up to the frame, the bracket or` supportinglframe F is curved outward and made of semicircular form, as shown in Fig. 6, and both this bracket and the bracket or frame G are supported and braced by rods t, extending drum to and bearing upon the frame A.

The bolting-cloth may be either of silk or wire, or of other suitable material.

The varying inclination of the blades causes the material to bemoved morerapidly through the reel at one point than at another, and also varies the force with which the blades act.

For the purpose of holding the slides O in their elevated position, I provide spring arms.

vided with journals lat its ends, and laterally-l adjustable boxes or bearings adapted to re-` ceive and support said journals.
