Application filed January 9, 1905. Serial No. 240,348.

To all whom it may concern:

Be it known that I, ORVILLE M. MORSE, of Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Dust-Collectors; and

I hereby declare that the following is a full,

clear, and'exact description thereof, reference being had-to the accompanying drawpart of thls specificatlon.

lugs, which form My invention relates to lmprovements 1n i-dust collectors, and more particularly to dust collectors wherein the air is freed from dust by passing it through a cloth, or fabric.

' The primary object of myinvention is to provide in a dust collector of the class describedan improved and highly efficient arrangementffo'r cleaning fabrics.-

A further object of my invention is to pro ride a dust collector of generally improved construction. V

More specific objects may be ascertained byreference to the following specification.

In the drawing: Figurel is aside elevation, with parts in section, of a machine embodymg my present invention. Fig; 2 is a Lplan view thereof.- 'Fig. 3is a transverse,

horizontal section on line 3 -3 of Fig. 1. Fig. i is a transverse vertical section on line 4;t of Fig, 2. Fig. 5 is a transverse vertical section of a single fabric collector elelrnent taken on line 5-5 of Fig. 6. Fig. 6

reference refer always to likeparts.

Referring now to said ,drawings, 11 indicates a suitable frame whereon is disposed a circular'floor 12 to which is secured a circular wall 13 coacting with said floor to form the lower section of a distribution chamber, the upper portion of which is the annular wall 14 and deck 15. Said deck 15 and wall 14 are rotatable, the joint between the wall l and deck 15 is preferably packed, as with sheep skin, as indicated at16.

Into thebottom of the floor 12, preferably at or near the center thereof, leads theair inlet spout 17, andimmediately above said inlet spout in the deck 15 I preferably provide anaperture and arrange incommunication therewith a cylinder 18, preferably of metal or otherimperforate material, and having its top closed as at 19.

Inthe deck 15 surrounding the cylinder 18 provided by laterally beyond j To provide are made a series of relatively large apertures 20.one foreach fabric collector element, any number whereof may be provided.

Various specific constructions of fabric-collector elements may be employed in the practice of my present invention, but the 'novel and advantageous construction which is best shown in Figs. 5 and '6, comprises a top plate or board 21 having a' plurality of apertures 22 therein, and having secured about its exterior a fabriccylinder opening at its lower end into the distribution chamber, and having suspended in each aperture22 a fabric tube closed and weighted at its lower end and open at its upper end.

, Specifically 23 indicates a fabric cylinder the length of which ispreferably greater :than the distance from the top board 21 to '75 therein near its lower end a pocket 24 wherethe deck '15, said cylinder having formed in is contained a-weight or weights, prefer- ,ably a long lead strip or series of short strips 25. Said weight 25 tends at all times to keep. the-upper portion ofthe cylinder 23 taut but below said weight the fabric cylinder is slack, as indicated at 23', for a purpose to be described.

. ;Union is through the agency ofa metallic band 26 forming a bushing for the aperture 20 and having its upper endaflange or heading 27 over whichthe loose portion 23 of the cylinder 23 passes. Astrap, cord or wire 28.is bound over the fabric 23, below the flange 27 and serves to tightly fasten the fabric to the band-2.6.

The fabric tubes -30, open at their upper ends, are secured withinthe aperpreferably effected between each fabric cylinder 23 and the deck 15 tures 22, as bymeans of-tacks or the like,

andv are freely suspended from such points of attachment. Preferably eachfabrictube 30 extends down to a the upper end of the band 26 and is secured point slightly above tothe reduced,'grooved portion 31 of a block 31, the lower portion of which projects 32 indicates a strap, cord or wire securing the fabric to the reduced portion 31' of the block 31.

yielding means for normally maintaining the fabric collector as a whole the lower end of the tube.

in predetermined position, I preferably secure to the top,board, 21, or to,a reinforcing strap 34 secured thereto, a rod 35 extending upward through an aperture 36 in oneof head 19 of cylinder 18, said rod 35-having on its upper end, a head 39 between which and the spider arm 37 is arranged a spring 4O tending to hold said rod in its uppermost position,'said position being determined by the contact of a sto 41 u on the rod with the under side of the spi er arm 37.

As a convenient means for jarring the fabric elements I provide a cam 42 mounted upon a main driven shaft 43 in such position that the rods 35,when the rotary deck member is turned, pass therebeneath, said shaft being mounted in suitable bearings 44' which are preferably vertically adjustable and provided with a pulley 45 or other means for applying power thereto.

When the rod 35 stands in vertical alinement with the shaft. 43, rotation of the shaft 43 would cause the cam 42 to strike and depress said rod at each revolution, but such a stroke would be shearing, and to prevent bending of the rod by such shearing stroke I prefer to provide between the cam and the head 39 of the rod a buffer member, one such member being herein shown as serving for all of the rods, said member specifically comprising a leaf spring 46, at one end secured to a convenient part of frame 11, as

at 47, and at its free end provided with a plate 48 of fiber or like material, which extends in such position as to lie between the cam 42 and any rod-head 39 that may pass ther'ebeneath.

If desired the fiber plate may be omitted and the spring 46 extended to underlie the cam, as described, but I prefer to employ the fiber plate, and'to make said plate of relatively large diameter and pivot it as at 49 to the spring 46. 1

I provide in the'machine means for automati'cally rotating the rotatable deck member and the parts associated therewith for movement,'such means being herein shown as a pawl and ratchet movement operated from the driven shaft 43.

- Specifically 50 indicates a worm wheel carried by the shaft 43 and meshing with the gear 51 mounted on an upright countershaft 52 supported in suitable bearings 53, and at its lower end provided with a crank 54, to which is pivotally connected the pawl 55 having a curved or hook end 56 provided at its extremity with a notch 56' arranged step by to overlie and engage with a circular crownratchet 57 mounted upon the deck member 15 preferably near the edge thereof, and having formed at its upper edge notches or teeth 58.

The ratchet teeth 58 are so disposed and the throw of the pawl 55 is such that the step rotation of the deck successively brings the stems 35 of the several fabric collector elements into position to be acted upon by the cam jarring mechanism at the en of the movement of the pawl, so that each stem remains in operative association with the. cam-jarring mechanism until the pawl has begun to make return stroke.

5959 are rollers mounted on wall 13 and bearing againstwall 14 for guiding the rotary deck member in rotation.

To provide means for segregating the fabric collector element being acted upon by thecam from the body of the distribution chamber and the other collector elements, I provide the radial partition walls 60 secured to the deck member 15 between the apertures 20, and extending inward to points adjacent the cylinder member 18, and arrange upon the floor 12 the curved wall 61 with which the partitions on both sides of the fabric element positioned for coaction with the cam may make contact, said wall 61 extending into close proximity to the deck member 15, so that by said wall 61 the walls 60 and the peripheral wall sections 13 and 14 there is laterally inclosed a chamber having-no communication with the distribution chamber.

aperture 62 communicating with the hopper 63 arranged within the shell 64 and at its lower and opening into'a conveyer trough 65 wherein is arranged a conveyer screw 66, suitably driven as by pulleys 67 and 68 respectively and the driven shaft 43, and the be t 69, said conveyer being adapted to convey material falling from the'hopper into the conveyer casin 65 to a suitable outlet 70.

Suitable provision is made for drawing air inwardly through the collector element segregated for cleaning, and to this end I provide in the shell 64' an opening which communicates the trunk 7 2 leading to mounted on the conver shaft 71 with In the floor member 12 is provided an.

the eye of a suitablefan 73. Obviously the 4 fan 73 may be the same fan that propels the dust through the inlet'17, or it may be a separate fan.

The action of the machine constructed as above described will be as follows: The dust ladenair propelled into the machine through the inlet 17 entersthe distribution chamber and the cylinder 18, and distributesitself to the several collector elements communicating with the distribution chamber. Through the fabric collector elements the air esca es,

passin outward'through the outer cylin ers 23 an inward to'the axes of the tubes 30 whence it escapes through the 'open ends thereof. In traversing the fabric the dust is deposited so that the air escapes in a relatively free condition. The shaft 43 being power driven motion 's communicated through the countershaft 52 to the pawl 55 which slides forward .and back upon the ratchet member 57, at each back stroke moving the rotary sociated collector elements a step in advance.

deck member with its asment is As heretofore described each collector elepositioned so that stem alines with the cam 42 at the end of a working stroke of the pawl, so that the elements dwell in such position during the interval of time in whichthe awl makes its next forward or "inactive stro e. During this interval the cam 42 makes a number of revolutions, ac-

cording to the gearing relation of the parts, and .at each revolution strikes upon the bufier plate 48 which communicates a blow to the head 39 of the stem 35, depressing said head against the tension of its spring 40 and then allowing it to snap back, giving the collector element a jerk.

I find that the buffer element serves two useful purposes. VVhen it. is omitted the machineis operative, but the shearing blows of the cam upon the heads of the stems tend to bend the stems, and furtherth'e blows of the cam upon the stems are accompanied by some noise. In the construction shown, however, the fabric buffer, secured to the spring 46 which extends in at right angles to the cam shaft, moves in a practically vertical line under the blows of the cam so that the shearing motion is not imparted to the stems 35, and, therefore, Further the buffer, being constructed of fiber or other suitable material, deadens the noise ofthe impact of the cam. The preferred construction of buffer shown is such that if wear takes place on one portion of the buffer it maybe rotated to'present a fresh surface to the action of the cam, and its life thereby lengthened. i

' It will be noted that the construction of each fabric element is-such that it provides a plurality of fabric members-the tubes 30each suspended from its upper end and free and weighted at its lower end, said members being. arranged within striking distance from each other so that when jarred their lower. ends may freely swing and strike each other; and that it further provides a fabric member-the cylinder 23-s uspended from its upper end, weighted near its lower end, and so loosely associated with the deck member that its weighted portion is free to swing and become distorted in various directions, while at the same time no free opening is ever left between the deck and the pocket supporting plate 21. This arrangement I find to be peculiarly advantageous. I find from experience that a fabric member interposed in the path of escape of the air suspended from its upper end and free and weighted at its lower end will, if jarred at intervals, to'cause the weighted lower end to jump around or dance, keep operatively clean for an indefinite period, and that the surface cleaned will not be confined to any' one locality of the fabric but that the entire they are not bent.

fabric members are so collocated that in dancing or jumping about they strike each other with their weighted end.

- In the specific construction herein shown it will be noted that provision is made to prevent the wearing of the cloth of the tubes by the blows of the weighted end of the adjacentfabric members, the blocks 31 being preferably so long that their lower edges strike each other rather than the cloth, and the cloth being held in upon the reduced portion 31 of each block.

During the'time a fabric element is being acted upon by the jarring mechanism, it is subjected to a reverse current, air being drawn by the fan 73 inward into the area inclosed within the'cylinder 23 through the fabric cylinder and through the tubes 22, so that as dust is shaken oil or loosened it is 'drawn downward through the opening 62 into the hopper 63, whence it falls into the conveyer trough 65 and it is conveyed by the screw 66 to point of discharge 70.

While I have herein described in some detail an embodiment of my invention which I find to be operative and successful in practice, Ido not desire to be understood as limiting myself to the specific details of construction thereof further than as specified in the claims, as it will be apparent that departures mightbe made in the construction without departing from the spirit and scope of my invention.
