AUTOMATIC FLGUR BOLT CLEANER.

SPECIFICATION forming part of Letters Patent No. 301,251, dated July 1,1884.

Application filed February 7, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, ALBERT F. Miisn, of South Vallejo, county of Sol'ano, and State of California, have invented an Improvement in Automatic Flour-Bolt Cleaners; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to that class of devices for cleaning the reels of fiour-bolts in which a brush is suspended over and its bristles come in contact with the exterior of the reel; and my invention consists in the novel arrangement and combination of devices, to be hereinafter explained, and pointed out in the claims.

The means for supporting the brush, the mechanism for connecting it with the drivingpower to accomplish its action, the means for throwing it out of gear, and the means for preventing undue wear of the gearing all form part of my invention, and will be fully explained. v

The reels of iiour-bolts are made polygonal, some having six, others eight, and others more or fewer sides, which are composed of fine silk stretched over ribs at the angles, on, which lines, for the purpose of preventing wear, ticking strips are secured. \Vhen the flour is at all damp, the mesh of the silk becomes clogged, and it is necessary to keep it brushed to permit it to perform its function. Various means are employed to accomplish this result, among which is an overhanging brush adapted to come in contact with the exterior surface of the silk. In some the whole weight of the brush rests on the silk and soon wears it out, and in others the brush is set at an angle on the reel and acts as a wiper rather than a brush, the difficulty in this being that such a brush becomes itself clogged up, as its bristles are not exercised so as to free themselves by agitation.

The object I have in view is to so suspend and connect the brush that its weight shall at all times be removed from the silk, and yet be so moved that whatever may be the contour of the reel its bristles shall come in light con tact with the silk to brush it, and jump over the ribs to prevent wear of the ticking strips.

Referring to theaccompanying drawings, Figure l is 'a perspective view of my automatic flour-bolt cleaner. Fig. 2 is a side view it is mounted to revolve by means of a central shaft, 0, to one end of which power is to be applied. The reel is fed in the usual manner through one end.

1) represents the silk sides of the reel, and D the ticking strips over the ribs (Z or anglelines.

Mounted transversely in the box above the reel is a shaft, E, from which arms 0 extend, which carry the brush F. One end of the shaft E is provided with a crank, G, having a slotted cm].

H is a metal piece, the lower portion of which is formed into a loop, h, from which a short arm, h, extends downwardly through a socket-arm, If, secured to the box or frame,

whereby the piece H is guided in its vertical movement. A bar, I, the upper end of which is connected with the crank G, extends downwardly behind piece H, guided by being let into said piece, and having a cross-head, I, on its lower end, which extends between the sides of loop 71 forming the upper side of the eccentric-strap, as I shall explain.

J is a bracket secured to the main frame, in which and in said frame is mounted a countershaft, K, on which is secured an eccentric, L, confined by the strap formed by loop h and cross-head I. This shaft carries a pinion, m, which meshes with a large gear, M, on the main driving-shaft.

The effect of the mechanism as far as explaincd is as follows: The power which turns the reel also oscillates shaft B, being transmitted through gear M and pinion or, countershaft K, eccentric L and its strap, bar I, and crank G. This oscillation of the shaftEraises and lowers the brush F. To give the brush its proper movement both in extent and time is a matter of calculation. For example, if the reel be hexagonal, the brush would have to rise and fall six times in the revolution of the reek-once for each side; therefore there would have to be six revolutions of the eccentric to one of the reel, which is accomplished by making the proportion of the teeth of the gear and pinion as six is to one. If the large have sixteen, and for every hexagonal reel this proportion would be maintained. For an octagonal reel the proportion would be as eight to one, and so on. This adjustment makes the operation of the brush certain for each side of the reel. As to the extent of the movement of the brush, this is governed by the size and character of the reel as to the number of sides, and is regulated by giving the proper throw to the eccentric. For a hexagonal reel the throw would have to be greater than for an octagonal one, or for any greater number of sides, because the greater the number of sides the less acute are the angles they form, and therefore the brush is required to have less rise and fall. In order to provide for such adjustment of the throw of the eccentric, I show a means in Fig. 4. The eccentric is slotted, and is fixed to the shaft by a setscrew, a, which allows, when loosened, the cocentric to move on the shaft nearer to or farther from the center, to decrease or increase its eccentricity, a block of wood, a, or other material being placed in the slot onthe opposite side, for the shaft to bear against when the screw is retightened. The eccentric is so formed that it gives to the shaft E just enough vibration to cause the brush to rise and fall in. a course conformable to that of the reel, so

- that its bristles shall come in contact with the gear, as I shall presently explain.

sides of the reel with sufficient pressure to brush the silk, and not enough to wear it out. If the brush were allowed to act over the ribs as well as over the sides of the reel, it would have a tendency to wear out the ticking strips D, which cannot sustain as much friction as the silk. I therefore provide means for giving the brush a sudden rise, sufficient to allow the ribs to pass under it without coming in contact with its bristles.

The bar I.is not fastened directly to piece H, and it has a supplementary movement of its own. It is provided with an elongated slot, i, through which passes a squared bolt, N, the end of which receives a nut, a. In the slot i, between this bolt and the bottom of the slot, is a spring, 0, which is guided and held to its place by a pin, 0, extending downwardly from the bolt, and a small pin, 0, extending upwardly from the bottom of the slot. Upon the header outer end of the bolt is fitted eccentrieally a disk or plate, 1, operating between guide-fiangesp on the piece H, the upper flange being grooved for the reception of the upper edge of the disk, whereby it is steadied and held in place. This disk, while serving the purpose of connecting the bar I with the piece H, is in reality a cam, by the operation of which the device is thrown into and out of The tendency of the spring O is to keep the strap tight upon the eccentric, and still allow for its yielding when necessary.

Upon'one side of the eccentric L is a cam, Q, consisting of a flange-strip, and upon the edge of cross-head I is a projecting lip or lug,

i, against which the cam Q impinges in the revolution of the eccentric, Fig. 3. This cam is so arranged with respect to the eccentric that its operation takes place as the ribs of the reel approach the brush.

Itlifts the bar I suddenly and to a sufficient distance to oscillate the shaft E enough to raise the brush to clear the rib as it passes under. When relieved of the cam Q, the strap returns to its normal position upon the eccentric.

The cam-disk P is provided with a leverhandle, It, by which it is turned, and I cut notches r in the guide-flanges p, with which the lever-handle engages to hold the cam in position. WVhen the handle is turned up, the parts are in gear; but when the cam is turned with its handle down, the bar I and piece H are moved in oppositedirections, thus allowing the strap to expand and relieve the eccentric, which no longer affects the brush. The parts are held separated by resting the handle-lever upon some part below, and in this connection I make this very adjustment serve the purpose of a brake to prevent the wear of the gearing.

Upon the counter-shaft is secured centrally claim as new, and desire to secure by Letters Patent, is-
