CENTRIFUGAL.. REEL.

SPECIFICATION forming part of Reissued Letters Patent No. 10,696, dated March 9, 1886.

Original No. 326,901, dated September 22, 1885. Application for reissue filed December 19, 18.15. Serial No. 186,232.

in the construction and the combination hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a longitudinal sectional elevation. Fig. 2 is a cross-sectional elevation on the line x w of Fig. 1, and with a portion of the head77 broken away to show the interior of the reel. Fig. 3 is an outside elevation of the feed end of the machine.

' Fig. 4 is an enlarged detail illustrating more fully the manner of securing the bolting-cloth on the heads of the reel. Fig. 5 is an enlarged perspective view of a portion of the feed-end head of the reel, illustrating more fully the manner of securing the cloth thereto. Fig. 6 is an enlarged perspective View of a portion of the interior supporting and exterior clamping frames.

In vthe drawings, 2 represents the framework, of any suitable construction, and having the usual conveyer, 3, in its lower part.

5 represents the main drivingshaft, journaled at one end in a bearing, 7, on a bridgetree, 9, and at the other end in a hanger or bridgetree, 11.

13 is a hollow sleeve or tubular shaft encircling the shaft 5, andjournaled at one end outside the casing 2 in a socket formed for itin the bearing 7, and projecting into the casing for some distance.

15 isa collar encircling the shaft 5 at the inner end of the tubularshaft 13, and adapted to be fixed to the shaft by a set-screw, 16, for bearing against the inner end of the tubular shaft and preventing an inward movement thereof. Another sleeve or tubular shaft, 17, e'ncircles the other end of the lshaft 5, and is journaled outside the casing 2 in a socket formed in the hanger 11, and passing inward through the frame, as shown. This hanger 11 will be constructed in any desired manner and attached to the casing 2 by a bridge-tree or other means, and will support a short horizoncounter-shaft 19, this counter-shaft being provided with a chain-pinion, 29, in line with a chain-wheel, 31, on the sleeve 17.

On the shaft of the conveyer 3, in a line below the pinion 29, isachain-pulley, 33, around which a chain, 35, extends, and from thence around a tightener-pulley, 37, to the chainpulley 31, fast on the sleeve 17, and thence around one side of the chain-pinion 29, fast on the shaft 19, and thence back to the conveyershaft. By this means the conveyer is driven from the shaft 19 by the c hain 35, while atthe same time, by its passage around the pulley 3l, the same chain imparts motion to the reel in the same direction as the beater-shaft.

By forming the pinion 25 smaller than he gear 27 the shaft 19 runs at a slower speed than the shaft 5, and by forming the chainwheel 31 larger than the chainvpinion 29 the reel will run slower than the beater-cylinder, but in the same direction.

A hub, 39, is fast upon the sleeve 17, inside the casing 2, and is connected by radiating arms 41 to a disk, 43, whileasimilar hub, 45, with an internal screw-thread, nts on a corresponding screw-thread,47, on the sleeve 13, and is connected by radiating arms 49 toa disk, 5l, the two disks respectively forming the head and tail ends of the reel. The hub 45 is adapted to be fastened to the sleeve 13 by ak setscrew,53, when required, as hereinafterset forth. An opening is made through the central portion of the disk 43, which is surrounded by a ring, 55, which closes the space between the disk and the end of the frame 2, as shown. The ring may be attached to the disk 43, as shown, or to the frame 2, as preferred.

57 is the feed-spout, leading through the open center of the disk 43as shown.

Y v i* 163,69;

59 isa disk surrounding the shaft 5, justinside the hub 39, and held in place and secured to the shaft by a collar, 61, having a setscrew,

63, as shown, this disk serving as a stop to the inflowing material from the spout 57. and causing by its revolution to spread the material outward and throw it against the cloth just at the moment it enters the-reel, and thereby insure the contact of the material with all parts of the surface of the cloth.

The disk 59 may be cast in one piece with the hub 39, if preferred.

Attached to the inner face of the disk 51 are a series of curved spouts or carriers, 65, converging toward the center, and turned outward through the central opening in the disk, as shown. A cylindrical sheet-metal ring,67, Surrounds the central opening in the disk 51, and projects toward the end of the frame 2, and is adapted to revolve with the reel. in the side of the dischargespout, as shown.

. By means o1' the cooperation ofthe curved spouts 65, ring 67, and discharge-spout 69 the tailings or the materialwhich fails to pass through the meshes of the cloth will be caught up by the spouts as the reel revolves, and fed into the spout 69, the ring 67 serving to prevent these tailings from falling into the conveyer 3.

On the inner face of the disk 43 is formed a ring or annular rib, 71, having a groove, 73. in its outer edge, yas shown more clearly in Figs. 4 and 5, and covered by a metal band, 75, secured to the annular rib by screws 77. This band 75 covers the groove 73, except at the ends of the` bands, which do not touch, leaving an open space,79, as shown in Fig. 5. Thesouter edge of the rim 71 is ofV less diameter than the rear part, so that a small space will be left between the band and the rim, as shown in Fig. 5, in order thatthe cloth or the binding may not' be pinched between the band and-the rim.

The groove 73 may be partially in the rim 71. and partially in the band 75, or entirely in either, as preferred.

The bolting-cloth 8l has a binding, 83 85,

. on each end, of ticking or other suitable material, with cords 87 S9 hemmed into the edges of the bindings.

To attach the cloth to the reel, the binding at one end, 85, is inserted into the groove 73, beneath theband 75, and drawn around the rib until its end emerges again from beneath the band in the open space 79. The binding must be long enough, so that when drawn around the rib 71 its ends will meet, as will also the edges ofthe cloth. The cord in the binder forms aswelled edge, which willlie in the groove 73, and cannot be drawn from Vbeneath the rib. The opposite end of the cloth is then carried over the edge of the disk forming the movable end ofthe reel. The binding is then drawn up ,by` thevcordto such an extent that it cannot passback over the: disk, and the ends of the cord are fastened together.

The screw-threaded sleeve 13 is screwed up against the collar 15, and the movable end of the reel is thereby moved longitudinally of the shaft in a direction away from the other end of the reel. to the movable disk, it can adj ust itself evenly over the disk. Every part of thje cloth will therefore be equally stretched, and no undue strain will be exerted upon any part.

ln putting on the cloth of boltingreels, where both ends of the cloth are attached to the reel ends, it often happens that some parts will be drawn a little tighter than others. Then if f the reel ends are moved to stretch the cloth some parts willl be strained and often torn. By my construction and arrangement this objection is entirely obviated. One end of 'the reel-cloth being attached to the fixed end, the other is loosely secured overthe movable end by drawing up the cord in its end. Vhen the disk is moved, the cloth will slip around until it is evenly adjusted; or, if necessary, while being stretched the cloth maybe adjusted by hand, and every part of it will be stretched alike. After the cloth has been stretched the edges are sewed or laced together in any suitable manner. f

Within the reel is a clothsupporting frame, which is attached to and moves with the movable end. This frame consists ot' a series of metal bands or hoops, 97,Which are connected together by one ormore longitudinal bars,99, which are secured at one end to the movable reel end. This frame forms an inside support for the cloth, and as it moves with the movable end it forms no obstacle to the stretching of the cloth. I provide also a sectional clamping frame, which is adapted to be firmly clamped over the outside ofthe reel, after the cloth is stretched, to securely clamp the cloth over the interior frame. y This frame consists ofa series of sectional hoops or bands, 103, and a series of longitudinal rods or bars, 107. The bands 1.03 are shown formed in two sections and provided with ears 105 and bolts 106, by which they may be fastened together. These bands may be formed in any number of sections that may be found convenient. Each section of each band is riveted or otherwise suitably fastened to one or more of the rods The ends of the rods 107 are screwthreaded and provided` with nuts 109,by which they are adjustably secured to the head end ofthe reel. The opposite disk or end, 51, has a groove in its edge, and the band on this end of the sectional frame is rounded or convex on its inner side and adapted to t into this groove. After the cloth is stretched the sections ofthe clamping-frame are put in position and the ends of the sectionalbands are fastened together. The nuts on the rods 107 are adj usted against the opposite faces of the head. The bands of the exterior frame are spaced equally with those of the interior frame, so that they come directly over the interior bands when in position. By this means the cloth is firmly As the cloth is 'not attached IOO IIO

supported and clamped at suitable intervals.- The convex end band projecting into the groove in the edge of the movable disk serves to keep that disk from moving toward the other disk, and thereby retains the cloth in its stretched condition. After the cloth is stretched and the clamping-frame is in place the sleeve 13 is screwed away from the collar 15, to prevent unnecessary friction. rI'he setscrew 46 in the 'hub 45 is setup against the tube 13, so that the reel and tube rotate together.

Ihe beater-cylinder is of the ordinary construction, consisting of beater-ribs 113, attached at an angle to the cloth 81 across the rims 115 of Wheels or spiders connected by arms 117 to hubs 119 on the shaft 5.

I claim a gieat advantage by the manner shown of constructing the cloth-covered reel without internal longitudinal ribs, except the one thin bar, 99, as the material,when thrown against the cloth by the rapidly-revolving beaters 113, strikes the cloth only, and is not obstructed by anything on the interior of the reel, the rings of the interior frame offering no obstruction, and the thinness of the bar of the frame causing the material to pass freely over it and not be affected thereby, except to a limited and immaterial extent, this bar not generally exceeding one-sixteenth of' an inch in thickness.

In reels having interior longitudinal ribs the material being thrown against them glances offand strikes the cloth with accelerated speed, and always in the same place, so that the cloth thus continuously acted 4upon wears faster than at other portions; but with my arrangement the cloth wears evenly on all its surface, as there is nothing on the interior of the reel to cause the material to act upon it with more force at one point than at another. This form of the reel also produces a better effect upon the material, as the result sought to be obtained is the separation of the particles, and not their disintegration.

In reels havinginternal longitudinal ribs the material is driven against them with great force and the particles broken, which result I wish to avoid in my machine.

I prefer to provide two pins, 121 and 123, adapted to be setdown through perforations in the ring or band 75, and through the binding 85 and into the rim 71. After the binding has been inserted under the band 75,these pins are put in place to hold the cloth at this end while the other end is being placed over the movable end and the longitudinal seam is being sewed or laced.

The collar 67 on the shaft 5 serves to keep the shaft from being moved through the casing by the pressure of the tubular sleeve 13 against the collar 15.
