BOLTlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 255,002, dated March 1.4, 1882.

Application filed Octobtr 8, 1881.

To all whom it may concern Be it known thatI, OavILLn M. Mossa, of Springville, in the county of Erie and State of New York, have invented new and useful Improvementsiu Bolting Apparatus, ofwhich the following is a specification.

This invention relates to thatclass of boilingmachines which are provided with an inclined bolting-surface and au elevating mechanism which faces the boltiug-surface, whereby the material to he bolted is repeatedly elevated and caused to tlow over the bolting-surface. l/Vhen bolting very ne material-forinstance, meal which has been deprived of the bran-the meshes ofthe bolting-cloth are liable to become more or less filled, whereby the operation ol themachinc is impaired and its bolting capacity reduced.

The object of my invention is to obviate this difficulty and to render the machine otherwise more reliable and uniformin its operation.

i My invention consists to that end of the pe- 'culiar mechanism whereby the meshes of the bolting-cloth are kept open, also, of the peculiar construction of the elevating mechanism, and of the means whereby the elevating mechanism is prevented from clogging; also, of the means whereby the low of the material over the bolting-surface is controlled, as will -be hereinafter iully set i'orth.

In `the accompanying drawings, consisting of four sheets, Figure l is afront elevation of my improved bolting apparatus with a part of the ease broken away. Fig. 2 is a top plan view thereof with a portion ofthe case broken away. Fig. 3 is a cross-section of the machine in line w x, Fig. 2. Fig. 4 is au elevation ot' the tail end ofthe machine. Fig. 5 is an enlarged cross-section of the lower part of the machine. Fig. Gis an enlarged cross-section of the upper portion ofthe bolting-surface and connecting parts. Fig. 7 is a longitudinal sectional elevation of the machine. Fig. S is a horizontal section fof the bolting-screcn and Wipers. Fig. 9^is a top planview of the belt and connecting parts whereby the wipers are operated. Fig. 10 is an elevation of the head end of the machine. Fig. 11 is an inside sectional elevation of the upper front portion of the machine.

(No model.)

Lilie letters of reference refer to like parts in the several figures.

A represents the inclosing case ofthe machine, secured to the frame A', both constructed in any suitable and well-known manner.

B represents the inclined boltiug-screen, consistin g preferably of a suitable num ber ot'screensections, covered with boltiug-cloth of proper mesh, and arranged side by side between horizontal ways b b', which are secured to the frame A of the machine.

l2 are openings formed in the case A, between both ends of the ways b, (Figs. 4 and 10,) for inserting and removing the screen-sections.

C represents the meal-chamber above the screen B, in which the elevating mechanism is arranged; and D represents the flour-chamber underneath the screen, which receives the material which passes through the screen, and which is provided with two conveyers. D D2, having cut-offs or slides d, whereby different grades of the sifted material can be commingled or be drawn olf separately at desire.

E represents a wiper or brush frame arranged to travel back and forth over the upper surface of the screen B. This frame is provided, as shown in Fig. 8, with tlexible strips e, of rubber or similar material, which bear against the bol-ting-cloth and remove the material which may adhere thereto. Two strips, e, are preferably arranged near together, whereby the rst strip will remove the material lying ou the cloth, while the strip following immediately after the first strip will bear upon the clean cloth and thoroughly dislodge the material which is contained in the meshes of the cloth. The frame E is made ofwood and very light, so that the pressure which the strips c exert upon the cloth is just sufficient to clean the cloth without, however, wearing or abrading the same. The frame Eis preferably made about halt' as long as the boltingsieve B, so that its movement equals one-half the length of the boltingsurface. The frame Eis supported by two bars, f, which project upward and hook over and slide on ahorizont-al rail or bar, f', secured to the casing of the machine in front of a horizontal slot', f2, formed in the front side of the casing. The frame E is op erated bya horizontal endless belt, G, arranged at the front side ot' the machine near the slot f2. The belt G runs over two pulleys, gg', and is connected with an upwardly-projeeting arm, f3, ot' the fra-nie E by a cord, chain, or rope, g2, whereby the frame E is drawn back and forth over the bolting-cloth. The pulley g is secured to a short shaft, which turns in a bracket, h, and which carries at its outer end a bevel-wheel. 7L. The latter is Vdriven by a bevel-pinion, h2, which is secured to the inner end of a horizontal shaft,v h3, its outer end being provided with a pulley, H, to which motion is communicated by an endless belt, h4, from a pulley, h5, mounted on the upper shaft of the elevating mechanism. The pulley g turns loosely on an arboror stud, which is secured to a bracket, g3. Both pulleys are free or unobstructed at their inner sides., so that the chain g2 can pass freely around the pulley with the belt.

I represents a wiperor brush fratrie arranged to traverse the lower surface of the boltingscreen B. This frame is provided with a number of upright bars, 1', which project into the panels or recesses formed on the under side ot' the bolting-screen B by the frames of the several screen-sections. The lateral movement of the frame I 'is limited to the length of one of these panels, anda wiper, t', is provided for each panel, which it is necessary to clean by such means. The lower horizontal piece, t2, ot' theframel is guided on arail, t3, secured tothe casing of the hour-chamber D, and the vupper horizontal piece, it, of the frame I is guided by means ot' earsj,which project downward from the casing. The horizontal top piece,t4, is preferably provided at its outer side with notches j', which permit the upperend of the .frame I to drop forward when it arrives at either end of its movement, thereby holding i the wipers away from the bolting-cloth While the frame I is stationary', and preventing the cloth from becoming worn by vibrating against the wipers. The fratrie I is operated by a chain, rope, or cord, j2, which connects the frame with the endless belt G, and which has sufficient slack or excess ot1 length to move the frame I only the length of one panel in each direction.

K represents a knocker, which is secured with its upper end to the frame of the machine, and which bears with its lower end against the bolting-sieve B.

k represents one or more springs, applied to the opposite end ot' the sieve B, for the purpose ot' jarring the same in connection with the knocker. The kncker is operated by a wheel, 702, provided with a suitable number of removable pins, which can be inserted or removed at pleasure, and whereby the knocker can be operated one or more times at every revolution of the wheel, as may be desired. The wheel 7a2 is mounted on a shaft, Z, which is rotated by means of bevel-wheels l Z2 from the lower shaft of the elevating mechanism.

' the machine.

M represents the driving-pulley, from which motion is transmitted by a pinion,mf, to a gearwheel, m', mounted on the lower shaft, m2, of the elevating mechanism.

n represents a gear-wheel, which is mounted on the opposite end of the shaft m2, and which transmits motion to the conveyers D D2 by means of an idler-wheel, n', and gear-wheels n2 n3.

As shown in the drawings, the elevating mechanism consists of three endless belts, 0 o o2, provided with buckets p. The belts run over a head-pulley or drum, P, which is provided with journals p', turning in bearings p2, attached to the frame A. qq g2 represent the lower' pulleys oftheelevating mechanism. rIhe pulley q is tirmly secured to the shaft m2, which turns in bearings Q' Q2, and the pulleys g q2 turn loosely on the shaft m2, whereby each of the three belts is enabled to move independentiy of the other belts, so that if either belt should move slightly faster or slower than the other belts the parts will not bind. The bucketsp are arranged most closely together on the head-belt o, less closely on the second belt, 0", and farthest apart on the tail-belt 02, as indicated by dotted lilies in Fig. 7, to correspond with the quantity of material which is to be elevated by each belt as the material decreases in quantity from the head toward the tail of The buckets p are secured t0 the belts by rivets r, which are provided with washers i", preferablyconstructedot'rubber or similar materiaharranged on the rivets between the buckets and the belts, to permit the belts to adapt themselves to the convex faces of the pulleys as the buckets pass around the same.

The endless belts of the elevating mechanism are arranged farther away from the boltiug-screen at the top ofthe screen than at the bottom, as shown in the drawings, in order to prevent the buckets from coming in contact with the screen by the sagging ot' the belts and to ati'ord the necessary room for the upper wiperframe, E.

R is a scraper-plate, secured to the frame or casing of the machine and arranged to bear against the-upper sides of the lower pulleys, g q q2, between both parts of each belt, for the purpose of removing from the pulleys any meal which may adhere to their faces, and which would, if not removed,y accumulate, and thereby increase the size of the pulleys and strain the belts. The scraper-plate R inclines toward the descending side ofthe belts, and discharges the material which is removed from the pulleys through openings R,fo1med in the belts between their ends, which are secured together by straps R2, or other suitable means, so as to form these openings. If preferred,

however, the scraper-plate It may be inclined,

or curved lengthwise, so as to discharge the material over the outer edges of the end pulleys between the legs of the elevator-belts, when no openings need be provided in the latter. i

IOC

Il: u

, Rais a flexible wiper or brush, attached to the lower edge of the scraper R, and bearing against the inner sides of the descending portions of the belts, so as to detach any material which may adhere to the belts. lhe material accumulates on the wiper until the openings R arrive opposite the lower end thereof, when the material is discharged through these openings. t

S represents delecting-boards, arranged in the upper portion of the meal-ehamber opposite the descending side of the head portion of the elevating mechanism. These boards are pivoted ats to the case, and connected by a bar, s', which extends to the outside of the case, whereby the position ot` the boards can be adjusted so as to accelerate or retard the movements ofthe meal toward the tail end of the machine, as may be desired.

S' is a shield or guard-board, which is arranged above the upper edge of the boltingscreen B and below the lower ends of the deflecting-boards, so as to prevent the material from falling directly from the head of the elevatingmechanism upon the bolting-cloth, as this would tend to Wear the cloth, and might force specks and impurities through the cloth. The board S compels the material, as it falls from the elevating-mechanism, to fall tirst upon the imperl'orate strip S2 above the upper edge of the bolting-surface,which strip is constructed of Wood or other suitable material, and re ceives the impact ofthe falling material. The latter descends from the strip S2 without any sudden shocks over the bolting-surface. The descent of the material over the bolting-surface may be retarded on the coarser grades ot' cloth, it necessary, by cords t, secured transversely b v gluing or otherwise to the upper surface of these cloths.

U represents the feed-spout, through which the material to be bolted is introduced into the case at the head of themachine; and U is the brandischarge spout, arranged at the tail end of the bottom ofthe casing. The top A2 ofthe casing A is preferably covered with cotton fabric or similar material, which permits the escape of the vapor from the meal.

The machine is slightly inclined from its head toward its tail, whereby the material is caused to move slowly from the feed end to the discharge end of the casing in a well-known manner.
