In the form of reel illustrated from Figs.

walls, A A, a top wall, A side walls, A A

and downwardly and inwardly inclined walls A" A. At the lower part of the casing are located two conveyer-boxes, B B, within which are located two spiral conveyers, C C.

D indicates, as a whole, a bolting-reel located within the upper part of the casing or housing of the machine.

D D are the reel-heads, which are attached,

by means of radial arms (l d d, to hollow sleeves or trunions D D which extend outwardly through the end walls, A A, of the housing, and are sustained in bearings cl d upon horizontally-arranged bridge-trees D D.

E is an exterior cylindric frame supporting the bolting-cloth E, and F is an interior frame attached to and rigidly connecting the heads D D and arranged concentric with the frame E, inside of the latter. The eX terior frame, E, consists, as shown, of longi- 9o tudinal ribs 0 and circumferential ribs c, said ribs being connected with each other at their points of intersection, so as to form an open-ended cylindric frame, which is separated from or unattached to the reel-heads.

The bolting-cloth E is stretched over and supported by the frame formed by said ribs 6 e. The interior frame, F, as shown in the drawings, is a trussed frame, substantially like the frame shown and described in a prior ap- 10o plication, Serial No. 214,145, filed by me upon the 21st day of September, 1886, and consists of oblique or spirally-directed ribs f f, at-

tached at their ends to the reel-heads D D arranged to cross each other, and secured together at their points of intersection so as to form a unitary truss. Longitudinal ribs f f are also attached at their ends to the reelheads and secured to the trussed ribs f f, while a series of circumferential ribs, f f extend around and are attached to the longitudinal ribs f f a The trussed reel-frame F is employed fo the purpose of giving a strong and rigid connection between the opposite reel-heads. The exterior cloth-supporting frame is made of thin strips of elastic material, preferably steel, giving lightness combined with strength and elasticity thereto, and the inner trussed reel-frame, F, is desirably made of similar elastic strips. The said interior trussed frame, F, is herein shown as employed to support an innerconcentric wall, F, which is provided with longitudinal slots or openings f said inner wall, F, operating in a manner and for a purpose fully set forth in a prior application, Serial No. 253,490, filed by me in the United States Patent Oflice upon the 27th day of October, 1887.

G is a central beater-shaft, and G l G are a series of revolving heaters supported from the said shaft G by means of frames or spiders G G The reel-trunnions D D are made hollow or tubular, and the reel-shaft G passes through and has bearings in the said sleeves. Upon the end of the shaft Gr, exterior to the sleeve D is placed a belt-pulley, G and upon said shaft, at one end of the machine, is placed a sprocket-wheel, g.

The conveyers G and C are driven by means of a chain-belt, 0 passing over the sprocketwheel g and over two sprocketwheels (one of which, 0, is shown in the drawings, Fig. 1) upon the shafts of said conveyers C G. The shaft of the conveyor 0 is provided with a sprocket-wheel, 0 over which is train ed a chain-belt, G passing over a sprocket-wheel, D", upon the trunnion D and driving the reel from the conveyer-shaft.

The feeding and discharging devices of the reel illustrated in the figures of the drawings, above referred to, are made as follows: The innerends of the radial arms (Z (1 cl d, which support the reel-heads, are set inwardly from the planes of the reel-heads D and D which latter are provided with central circular apertures. At the inlet end of the reel a short horizontal tube or shell, D, is attached to the inner surface of the end wall, A, of the housing concentric with the trunnion D and extends inwardly through the central aperture of the reel-head D.

(Z is an inlet-spout extending through the end wall of the housing and connected with the tube D Attached to the said sleeve D within the shell D is a short spiral conveyer flight or propeller-blade, (1, which operates in the rotation of the trunnion to carry inwardly material delivered through the spout (Z into the shell D, and to discharge the same from the inner open end of said shell into the reel.

1 have herein shown the reel as provided at its inlet end with a basket, D of woven wire or other suitable material, for the purpose of catching and retaining dough balls, pieces of metal, or other large objects which may become mixed with the material to be bolted. The basket D is shown as attached at its margins to the reel-head D exterior to the arms (I d, and as extending inwardly around said arms.

At the discharge or tail end of the reel I have provided a short tube or shell, D attached within an opening in the wall A of the housing and extending inwardly through the central aperture of the reel head D The shell D is closed at its inner end by a vertical end wall, which is fitted around the trunnion D and said shell is provided with an opening in its top within the reel, through which opening material from the reel is deposited within the shell.

Upon the trunnion Dis secured a conveyorflight or spiral propeller, (Z acting to carry endwise tl'irough the shell and to deliver from the outer end of the latter the material deposited therein. The material within the reel is delivered to the shell D by means of radial spouts d (1, secured to the head D and provided at their outer ends with lateral openings arranged at the sides of the spouts which face upwardly at the upgoing side of the reel, the inner ends of said spouts being arranged to discharge into the shell D at the time said spouts are at the upper part of the reel, in a manner fully set forth in a prior application, Serial No. 234,485, filed by me in the United States Patent Office April 12, 1887.

The exterior cloth-supporting frame, E, is, in the construction shown-in Figs. 1 and 2, sustained from the inner frame, F, by means of flat springs 6 e arranged longitudinally of the reel and attached at their opposite ends to the said frames E and F. As illustrated in Fig. 11, a similar spring, 6 is shown as arranged in a plane transverse to the recl-axis, between the said frames E and F, with the same general result. In either case the springs afforda yielding or flexible connection between the outer cloth-supporti n g frame, E, and the trussed frame F, such yielding or flexible connection allowing the said outer frame and the bolting-cloth thereon to be shaken, jarred, or vibrated to facilitate the bolting action of the reel, and to aid in clear-- ing the latter from adhering particles material being bolted.

Any suitable number of springs may be employed to support the outer movable frame, E, as may be found convenient or desirable, and such springs may be disposed in any preferred manner-as, for instance, they may be located at both ends of the reel or at the middle thereof only. In the particular eonstruction illustrated. in Figs. 1 and 2 a single set of of the springs, 6 e are arranged around the center of the reel, so that the exterior frame, E, is supported by the springs at its middle part only.

It will of course be understood that spiral or other springs may be employed in place of the flat or leaf springs illustrated.

The cloth-supporting ribs, when supported by springs in the manner described, may be jarred or vibrated in any manner found convenient or desirable. In some cases no special devices for shaking or jarring the cloth may be found necessaryas, for instance, the cloth-supporting ribs may be hung upon very flexible or elastic springs or spring-arms in such manner as to be very sensitive to vibration. In such case the striking against the cloth of the material being operated on as such material is thrown outwardly by the revolving beaters, as in a centrifugal reel, may cause sufficient jar or vibration in the reelcloth to very considerably add to the efficiency of the reel. I11 other cases, however, suitable jarring or shaking devices may be employed to vibrate or jar the cloth-supporting frame or the ribs which immediately support the cloth. I have herein shown in Figs. 1 and 2 jarring devices in the nature of knockers adapted to act upon the flexiblysupported frame E as the reel revolves.

At the upper part of Figs. 1 and 2 and in Fig. 3, H is an arm or bar hinged at h to the upper wall, A of the housing, and provided at its free end with a head, h, resting upon the surface of the frame E, and adapted to engage a series of knobs or projections, 6' 6 upon the outer surface of said frame. As the reel is revolved, the projections e 6, upon coming in contact with the head h of the knocker, will lift the said head, which will fall against the frame as the projections pass from beneath it, and thus give a series of blows or concussions calculated to shake or jar the cloth-supporting frame.

At the lower part of the reel, in Fig. 2 I having shown another similar jarring device, which may be used in place of or in connection with that above described. H, in said Fig. 2, is an arm or bar pivoted at 7L2 upon the inclined wall A of the casing, and having a head, 7L3, adapted to engage the projections e 6 upon the frame E. The said bar 11' extends outwardly through the wall A and to the said wall is attached a spring, 72 which acts upon the projecting end of the bar in such manner as to periodically throw the head it into contact with the frame E.

The projections e 6 may be made or formed upon the exterior surface of the frame E in any convenient or preferred manner. A

novel and advantageous means of forming said projections is, however, shown in the drawings, Figs. 2 and 3, wherein a leather strap or band, E is placed around the reel over one of the circumferential ribs e thereof, said leather band consisting of a series of short pieces or sections, ea e", the ends of which are connected by being turned outwardly and riveted or otherwise secured together face to face, in the manner shown, said outturned ends of the sections 6 e forming the projections e 6 In this construction a leather bearing-surface is formed, against which the knockers II or H act, while at the same time a cheap and simple means is provided of forming the projections e e and securing the same to the cloth-supporting frame E.

WVhen the exterior cloth-supporting frame, E, is sustained by springs connected at its middle part only in the manner illustrated, radially-arranged studs f may be attached to the inner frame, F, and extend outwardly to a point near the exterior frame, said studs being arranged near the ends of the reel, so as to limit the inward motion of the exterior frame and to hold the same at all times approximately concentric with the other parts of the reel under the action of the knockers thereon.

The ends of the cloth-supporting frame E are, as before stated, located adjacent to and a short distance inside of the reel-heads'D D and in order to make a close joint between the bolting-cloth at the ends of the clothsupporting frame and the heads of the reel to prevent escape of the material being bolted at this point, flexible sections or bands E of cloth or other flexible material, are attached at their opposite edges to the ends of' the cloth-supporting frame and to the margins of the reel-head, said flexible strips or hands being made sufficiently loose to allow the clothsupporting frame to freely move when shaken or vibrated.

The flexible band or strip E may be secured in any desired manner to the cloth-supporting frame and to the reel-head. In the particular construction herein shown and more clearly illustrated in Figs. 5 and 6 the strip E' is tacked, sewed, or otherwise attached to a leather strip, 9, (herein shown as made in two thicknesses,) which is cemented, riveted, or otherwise secured to the outer surface of the circumferential rib e at the end of the cloth-supporting frame.

E is a flexible strip of cloth attached to the edge of the bolting-cloth for convenience in stretching the latter over the frame in placing it upon the reel. The strip E is herein shown as extended over the strip E and also secured to the reel-head, the said strip E being also tacked or otherwise secured to the rib e in order to keep the bolting-cloth tightly stretched over the frame. Said strip E is shown as attached to the head by being nailed or tacked to a wooden ring, E secured to the outer margin of the metal part of the head.

I have herein shown in Figs. 2 and 3 an improved cloth-cleaning device, of which the hinged arms II II of the jarring device form a part.

IIO

H Figs. 2 and 3, is a flexible strap or cord which is attached to the two arms H H at op posite ends of the reel and extends in a straight line between said arms and is inserted at its ends through holes in the end walls, A A, of the housing. The said strap or cord is held taut by means of springs 77,5 7L5, (herein shown as of spiral form and as located between the exterior surface of the outer casing and plates h 76, attached to the ends of the cord.)

II is a sheet or strip of fabric attached at its upper edge to the cord II and extending from end to end Of the reel. Said sheet or strip of fabric hangs from the cord in such manner as to fall and rest upon the boltingcloth and thereby act to brush the latter as the reel revolves. The said strip I1 is preferably made of open fabric like mosquito-netting, and is desirably folded or bunched at its free edge to give it weight and to increase its brushing action upon the cloth.

In the operation of the cloth-cleaning device made as above set forth the studs or pro jections e c, acting upon the arms H II as the reel revolves, serve to periodically raise and lower the fabric strip 11 thereby shaking the same, so as to free from it adhering particles and at the same time to increase its action on the bolting-cloth.

I have found the operation of the clothcleaning device to be greatly improved by placing the series of studs or projections e c at one end of the reel opposite the spaces between the studs at the opposite end of the reel; or, in other words, by placing the two sets of studs at intermediate angular positions, so that first one and then the other of the arms II II is raised as the reel revolves. By this construction a waving motion is given to the fabric II, calculated to greatly aid in the dislodgment of adhering particles from the bolting-cloth. The springs 7r 7r are for the purpose of keeping the cord 1P stretched taut, and such springs may, for this purpose, be arranged otherwise than as shown, and one spring instead of two may be used with substantially the same result.

The bridge-trees 1), (shown in Figs. 1 and 4,) instead of being rigidly secured to the frame of the machine, as common heretofore, are provided at their ends with journals (1 d, which engage bearing-boxes (Z7617, bolted to the uprights a a of the frame, thereby allowing said bridge-trees to rotate freely about their longitudinal axes. As shown in said figures, furthermore, the bearing-boxes d, instead of being rigidly attached to the bridgetrees, are made separate therefrom and pivotally connected therewith in such manner as to turn about the vertical axes. The pivotal connection between the said bearing-boxes d and the bridge-trees, as herein shown, is formed by means of set-screws d (Z inserted through opposite sides of a central ring, (1, cast integral with the bridge-trees, and en gaging at their inner ends bearing-apertures (1/ (Z in the top and bottom surfaces of the said bearing-boxes.

The construction described obviously affords a universal joint or connection between the bearing-boxes and the stationary part of the frame, so that said boxes are free to adjust themselves in alignment with the shaft,-

thereby affording automatic adj ustmcnt of the boxes to the shaft and preventing possibility of unequal wear of the shaft journal or boxes, notwithstanding any shrinking, warping, unequal settlement, or distortion in any manner of the machine-frame.

B B B Figs. 1, 2, S, 9, and 10, indicate a series of inclined gates arranged at the bottom of the housing or casing, with their lower edges over the partition I), which separates the conveyor-boxes B B, said gates being for the purpose of delivering the material coming from different parts of the reel to either of the conveyer-boxes, as desired.

B are vertical transverse partitions extending over the conveyer-boxes and reaching to the lower margins of the bottom walls, A' A", of the housing. The several gates or cut-off valves B B are located between the said partitions B B", and are adapted to be swung at their upper edges laterally between said partitions in such manner as to bring their upper edges beneath either one or the other of the said walls A A", so as to cast or deflect the material passing downwardly through the housing to either one or the other of the conveyer-boxes B 3.

B B are inclined horizontal covers for closing the spaces between the lower edges of the walls A A and the top margins of the boxes 13 B. Said covers are adapted to be opened or removed for manipulating the cut-off valves 13 B in a manner heretofore common and well known.

As far as above described the cut-off valves are constructed and operate in a manner heretofore common and well known. As an improved construction in such valves, however, I make them as follows: In the vertical edges of said valves, which come in contact with the partitions I 13 are formed longitudinal grooves I) b,within which is placed and held a granular packing, such as fine shot, wheat, or coarse middlings.

As heretofore made the cutoff valves have been fitted closely at their edges against the partitions B B, for the purpose of making a tight joint between the same, and to thereby prevent leakage of the material around the valve. A construction of this kind has been foiind objectionable, however, for the reason that the partitions are liable to shrink or warp and seldom long remain in position to allow the free working of the valves. In the construction proposed by me I make the valves themselves somewhat narrower than the spaces between the partitions, provide grooves in the ends of the valves, and fill the said grooves with granulated material, which latter is held in the grooves and thereby forms a packing which will adjust itself to the adjacent surface of the partition and bars L L may be moved at the same time and to the same extent in the rotation of the shaft. At points inside of the trunnion the bars L L are attached to outwardly bent or deflected arms Z Z which extend outwardly through the frame F and are connected with the exterior frame, E. The shaft L is provided at its end with a belt-pulley, L by means of which motion is transmitted to the shaft. For the purpose of confining the ends of the bars L and holding the lugs Z in engagement with the cam-groove, a recessed collar, Z is herein shown as secured to the shaft and provided with a flange embracing the ends of the said bars L L, in the manner clearly shown in Fig. 18.

In all of the several forms of the reel above described the cloth-supporting frame is shown as sustained from an inner reel-frame attached to the heads. This construction is not, however, essential to the carrying out of the main features of my invention, and the cloth-supporting frame may be sustained by other means from the reel-trunnions or shaft-as, for instance, the frame E may be supported directly from the heads, in which case the inner reel-frame, F, may or may not be present, or the exterior cloth-supporting frame may be attached by spring-arms to the trunnions, or the heads themselves may be flexible and form the elastic or yielding support for the clothsupporting frame. A construction of the kind last referred to 1s shown in Figs. 20 and 21, wherein is illustrated a reel embodying the following features: The radial arms d d, by which the head is supported from the reel-trunnion D are attached at their outer ends to a ring, M, to which is secured a series of flat radial arms, M, made of thin metal, preferably steel. At their outer ends the arms M M are attached to and support a ring, M forming the outer margin of the reel-head. The space between the rings M and M is filled or closed by means of a covering, M of closely-woven cloth or other flexible imperforate material. The exterior cloth-supporting frame, E, is attached to the exterior ring, M of the head, such frame in the particular construction illustrated being a trussed frame or one embracing oppositely-directed spiral ribs secured to each other at their points of intersection and exterior cloth-supporting ribs sustained thereon. In the particular construction of the parts illustrated a wooden ring, m, is secured to the exterior surface of the ring M, both to afford a means of securing the cloth M and to form a suitable joint with the cylindric shell D of the feeding devices. An exterior wooden ring, m, affords a means of securing to the reel-head the ends of the bolting-cloth and the exterior margins of the cloth covering M The bolting-cloth and supportingframe therefor in a reel having flexible heads, such as is above described, may be shaken, vibrated, or jarred by either of the devices herein shown, and hereinbefore described, or by any other jarring or shaking devices. In the case of a centrifugal reel, furthermore, any special jarring or shaking device may sometimes be dispensed with, and the impact of the material thrown against the boltingcloth or the action of the beaters in passing through the material upon the cloth alone relied upon as a means of vibrating the cloth. In said Figs. 20 and 21, however, I have illustrated a simple device for jarring the boltingcloth endwise adapted for use in a reel with flexible heads. Said jarring device is made as follows:

m m m are a series of projections or teeth secured to the vertical surface of the exterior ring, M of the reel-head, said teeth or pro jections being preferably beveled or inclined upon their sides, which are in advance in the rotation of the reel.

m is a stationary stop or projection secured to the adjacent end wall, A, of the housing and located in position to be encountered by the teeth or lugs m m as the reel rotates. The said projection m will serve by acting upon the inclined surfaces of the teeth or lugs m to thrust the exterior. part of the reel bodily endwise, and as each tooth passes the said projection the resiliency of the arms M of the heads will cause the return of the exterior part of the frame to its normal position, thereby bringing the exterior ring forcibly in contact with the stop m and jarring or shaking the bolting-cloth.

In Figs. 22 and 23 I have shown a construction of the reel wherein the reel-heads are rigid and the cloth-supporting frame has sliding connection at its ends with said reel-heads.

D, Figs. 22 and 23, is a reel-head, and E is the exterior cloth-supporting frame, shown in this instance as formed by spirally-arranged intersecting truss-ribs e 6 longitudinal ribs 6, and circumferential ribs 6, forming a unitary truss, in the same manner as before described. The frame E terminates short of the outer margins of the head D, and a flexible strip or band, E is employed to connect the head with the end of the frame E in the same manner as before described. In this instance the cloth-supporting frame is sustained upon the head by means of longitudinal strips or bars N N, attached to the frame and extending through guide-apertures n in the head D. The strips or bars N are herein shown as being made integral with or prolongations of the longitudinal ribs 6 of the cloth-supportin g frame. I have herein shown anti-friction rollers 02 as located upon the head D inside of the supporting-strips N N, thereby enabling said strips to be moved in the guideapertures n with a minimum of frictional resistance.

An endwise vibratory or shaking movement may be given to the cloth-supporting frame E when the latter is sustained from the heads by strips N N, in the manner described, in

either of the ways hereinbefore set forth, and

in connection with such endwise shaking movement the reelframe may be jarred or vibrated by a knocker acting against the inside or outside ofthe frame, the said supporting bars or strips N N obviously affordin an elastic support or connection between the clotli-su 'lporting frame and the reelheads, allowing the supportingframe to shake or vibrate laterally when acted on by a knocker or jarring device. Commonly the longitudinal ribs e e and supporting-bars N N will be made of continuous strips of thin steel, as will the other parts of the clotlii-supporting frame, thereby giving lightness and strength to the structure, combined with a desired degree of flexibility.

A device for shaking the bolting-cloth and its supporting-frame E in a direction endwise of the reel is illustrated in Figs. 22 and 23, which differs from either of those before described. n a in said figures are rollers attached to the ends of two or more of the sup porting-bars N N outside of the reel-head, and N is a stationary cam-ring attached to the end wall, A, of the housing and provided with an undulating camface constructed to engage the rollers 71 of the said supportingbars as the reel rotates, and thereby thrust the cloth-supporting frame E endwise.

The clotlrsupporting frame may be held with the rollers in contact with the cam-rin g by any suitably-applied spring, leaf-sprin gs 72 91 attached to the outer surface of the reelhead and engaged at their free ends with the bars U N, being herein shown as applied for this purpose.

In said Figs. 22 ant 23 I have shown still another form of knocker or jarring device applied to the exterior cloth-supportin g frame, F.

In said figures, O is a metal rod or bar arranged transversely within the reel and secured at its opposite ends to the frame E, which supports the bolting-cloth.

O is a weight constructed to slide freely upon the rod, which latter is provided with shoulders 0 0 near its ends, limiting the ezc tent of movement of the weight. In the par ticular construction illustrated the shoulders 0 are formed by means of short metal sleeves 0 0, which are secured to the ribs of the frame E, and within which the ends of the rod 0 are inserted and held.

The means herein shown for securing the sleeves 0 o in place consists of strips 0 0 of leather or sheet metal, which are centrally perforated for the passage of the rod, rest against the inner ends of the sleeves, and are secured at their ends to the ribs of the frame. As the reel revolves the weight 0 will slide upon the rod first toward one end and then toward the other as the opposite ends of the rod are brought upwardly at the rising side of the reel. The weight comes in contact with the shouldero in each movement of said weight, and thereby produces a shock or jar which is transmitted to the frame F.

In case the jarring device last above described isused in connection with a reel having a central shaft, the red 0 may be placed at one side of the shaft, or it may be bent in its middle part to pass the shaft, in the manner indicated in dotted lines at 0, Fig. 23.

o o are leather washers placed around the rod 0, at the inner ends of the sleeves, to receive the impact of the weight.

A bolting-reel, the cloth-supporting frame of which has elastic connection with the reeltrunnions, may be both shaken for the purpose of bringing the finer and heavier portions of the mass of material upon the cloth downwardly into contact with the cloth, and also knocked or jarred for the purpose of freeing from the cloth particles which adhere to and clog the meshes of the same. A reel frame containing both shaking and knocking devices is shown in Fig. 24-, the shaking devices shown in said Fig. 2- being identical with those illustrated in Fig. 12 and the knocking devices identical with those shown 111 Fig. 15. A

All of the parts illustrated in said Fig. Bl are lettered in a manner corresponding with the parts shown in Figs. 12 and 15, and any detailed description thereof is not therefore necessary.

The flexible or elastic arm s jj, by which the reciprocatory motion of the bar J is transm1tted to the exterior cloth-supportin g frame, are, as shown in said Fig. 24, arranged to cross the similar arms, 7t it, by which the shaking or jarring motion of the bar K is similarly trans: mitted to the exterior frame. Said arms are sufficiently rigid to perfectly transmit the reciprocatory motion of the bar J to the clothsupporting frame while having sufficient elasticity to allow the frame to be jarred or shaken by the action of the knocking device operating through the bar K. The reciprocatory or shaking movement given to the cloth-supporting frame is notintended as a substitute for knocking or jarring, such as has heretofore been used for freeing the cloth meshes, but is intended to act upon the mass of material upon the cloth in such manner that the finer and heavier portions will be brought downwa'rdly into contact with the cloth and in position to pass through the same while the coarser, lighter, and fluffy material is brought to the top of the mass. The knocker or jarring device acts upon the cloth-supporting frame to free from the cloth particles of ma terial which adhere to the cloth, and, unless removed, clog the meshes of the same. The knocking or jarring devices, on the other hand, perform a different function from the cloth-cleaner Iii, (shown in Figs. 1 and 3,) which is for the purpose of removing adhering particles from the exterior of the cloth.

An elastic or spring connection between the cloth-supporting frame or the ribs which immediately support the cloth and the reeltrunnions or other supports has important advantages as a means of movably sustaining the said cloth-supporting frame, and this construction is therefore herein broadly claimed as partof my invention.

I claim as my invention 1. A bolting-reel comprising a cloth-supporting frame and spring-arms sustaining said cloth-supporting frame from the reel supports or trunnions, substantially as described.

2. The combination, with a reel embracing a cloth-supporting frame sustained from the reel-supports by elastic or spring connections, of a jarring device acting upon said clothsupporting frame, substantially as described.
