DUST-COLLECTOR FOR ELouR-MILLS.
Y SPECIFICATION forming part of Letters Patent No. 272,473, dated February' 20, 1883.
A ppncanon ined July 7, 1831. (No model.)
To all whom it mot/ concern:
Be it known that I, FAUsrIN PRINZ, a subject 0f the Emperor of Germany, and a resident of Dundas, in the county of Rice and State of Minnesota, have invented certain new and useful Improvements in Dust-Collectors for Flour-Mills, &c., of which the following is a specilication.
This invention relates to the apparatus used in flour-mills, Src., for removing the dust from the air, especially thatV passing through middlings-puriiiers and similar machines; and it consists in a cloth-covered frame or balloon, through which the air is caused to pass, and adaptedvto be revolved, and pro-vided with mechanism for shutting off the air from a portion of the cloth, and knocking or shaping such shut-ofi' portion to remove the adhering dust therefrom, as hereinafter set forth.
The invention further consists in a system of perforations and shutoff-rings, Src., whereby a back-draft of air through the shut-off section of the cloth is obtained to assist in removing the dust from the cloth, as hereinafter Yset forth.
I accomplish these results by the use of the mechanism illustrated by the accompanying drawings, in Which- Figure l is a cross-sectional view, and Fig. 2 is alongitudinal sectional view. Fig. 3 is an end view ofa portion of one end outside, showing the manner of revolving the balloon. Fig. ltis a detached detail view of a portion ofthe balloon and shutoff devices, illustrating the manner of operating the knocking mechanism; Fig. 5, a detached perspective view/of knocker;
Fig. 6,-a detached view of a portion of the outside of the casing and fan-case, illustrating the manner of revolving the balloon-operating shaft. y
This device may be applied to any style of middlings-puritier or similar machine, or arranged separately therefrom, aud large enough to receive the air from several machines, and consistsin an outer casin g or frame, A', through which the air from the purifiers, Src., is caused to pass, either by adjustable valves or through ports A2.
the heads B B2 are L-shaped rings d d2, titv ting through circular openings through the sides of the casing A and between the casing and heads of the balloon, so as to form bearings upon which the balloon B B2 b b2 o may be revolved, andto prevent the air from passing` into the open space which would otherwise exist between the casing and heads of the reel or balloon, as hereinafter shown.
Outside of the casings A', covering the central openings into the balloon, suctionfans C G2 are arranged, by which the air may be drawn from the casing through the cloth o.
Beneath the balloon a shaft, D', is mounted, and` adapted to be revolved by a system of dogs, o c2, and levers D2 D3, acting upon a ratchet-Wheel, D4, the lever D3 being vibrated, in any suitable manner, by the mechanism of the purifier or other machinenear the balloon. Near onev end of this shaft D an arm, D5, is
secured, and adapted to act upon -arow of pins, g, upon one end of the balloon, to revolve the balloon the distance of one of the pins at every revolution of the shaft.
Beneath the balloon are two upright .plates or partitions, E E2, connecting the lower part of the balloon and the bottom of the casing A together, and forminga compartment, E3, and Y upon the shaft D', near thecenter of this compartment, is a disk, D6, provided with pins h, adapted to act upon an arm, i', attached to a spring-knocker, i2,'so that when the pins h forcepthe knocker down and then release it its recoil will'cause the hammer i3 to strike one of the ribsb' a sharp blow, to shake the dust loose from the cloth o.
Running through the open interior of the balloon is a convex plate, F, attached at either -end by thin plates m m2 to the casing A' inF side the fan-'casings, and covered on its lower side withfelt, rubber,'or other suitable flexible material, u, and beneath which the ribs b2 run when the balloon is revolved, the felt packing forming an air-tight joint between the plate and ribs to preventthe air passing through the sections of cloth c that happen to be beneath the plate. By this means an air shutoff is formed for all the cloth c between the partitions E' E2 and shut-olf plate E, (in the drawings showing three complete sections of the cloth,) so that all the cloth above the compartment E3 is removed from the influence of the air to permit the dust to fallinto the compartment E.
By providing the disk DG with a number of the pins, h, the knocker is made to act upon the' ribs b' any desired number of times, while the balloon is held stationary between the actions of the arm D5. Thus a number of light blows are struck upon the ribs supporting the cloth during the time the blast is shut ofi" from each co1npartment,which producesa much better result than if one heavy blow were struck, as in the latter case no more dust is shaken loose, while the injury to the frame-work and cloth is quite apparent.
The lower part of the compartment E3 will he hopper-shaped and opening into a conveyer or spout, E4, by whichthe dust may be carried from the machine.
Paekin gs of rubber or other ilexible m aterial will be arranged between the casing A' and L-shaped bearin gs d' d2 to form air-ti ght joints to prevent the escape of the airat'these points.
'lhe balloon may be set in an upright position and the fan or fans placed at any point away from it, or the shut-olih plate F secured in any other desired manner.
The collector may he set in the ordinary dust-room of a mill, and the air from the puriers, Ste., blown through it.
rIhe revolving mechanism D5 g will beso constructed that the balloon will be revolved, each ot' its movements quickly, so that no delay occurs at these points.
One of the pins It, it will be observed, is wanting at the proper pointh2 in relation to the arm D5, so that the knocker will not be acted upon while the balloon is being revolved.
Through both of the heads B' B2, between every other section ofthe cloth c, perforations t' are made, and through the sides of the casing A, opposite the center of the compartment E3, similar perforations, t2, are made, corresponding to the perforations t', while rings t3 between the heads B' B2 and casing A' act as stops to shut off the air and prevent its pass-A ing through the holes t', except as they pass by the holes t2. By this meansastream of air from the outside is permitted to flow in between the sections'of the cloth that are shut off from the suction by the plate F and partitions E' E2 to form a back-draft through the cloth, so that the adhering dust will be forced out of the cloth and the knockers assisted in their work.
I do not wish to confine myself to the particnlar form of mechanism shown for operating this collector, as I am aware that it may be operated in many ways.
In this application means are shown for striking or knocking the dust-collecting medium in the direction of the tension of the medium; but no claim is made thereto, as I prefer to claim the same in a separate application, as well as the same feature in connection with the cut-olf plate, broadly, and I expressly reserve that right.

3. The combination of the balloon B' B2 b' bz c, shut-oil' plate I, casing A', fans C' C2, and partitions E' E2, substantially as set forth. A
4. The balloon B' B2 b' b2 c and casing A', in combination with the shaft D', arm D5, and pins g, substantially as set forth.

9. In a dust-collector, the combination of a dust-collecting medium, a shut-off for isolating one portion ofthe medium from the other portion, and means for admitting an air-current to the isolated portion to form a back-draft to aid in clearing the isolated portion from dust, substantially as set forth.
l0. In a dust-collector, the combination of a dust-collecting medium, a shut-off for isolating one portion of the medium from the other portion, means for jarring the isolated portion, and means for admitting an air-eurrent to the IIO isolated and jarred portion to form a backshut-olf portillon while shut oi, substantially draft to. aid in clearing the isolated portion as and for the purpose specified.
