DUST-COLLECTOR.

SPECIFICATION forming part Of Letters Patent NO. 675,397, dated June 4, 1901.

Application filed December 17,1900. Serial No. 40,219. (No model.)

To all whom it may concern.-

Be it known that I, ORVILLE M. Monsn, a citizen of the United States, residing at J ackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Dust-Collectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventiop relates to improvements in dust-collectors, and more particularly to the class of dust-collectors having a series of radial pockets of air-filtering material revolving around a conveyer to receive the collected dust and provided with mechanism to discharge the dust from the pockets intothe conveyor.

The objects of my invention are to provide more effective means of discharging the dust from the pockets, to reduce the noise made by the jarring mechanism, to provide improved means of adjusting the parts, to provide for adjustment of the parts while the machine is running, and to provide the device with Various improved details of construction,as hereinafter more fully described, and particularly pointed out in the claims.

My invention consists, essentially, in making the pockets in detachable sections, each section consisting of a number of pockets formed of a continuous strip of filtering material, providing the pockets with sliding cleaners, connecting the pockets in pairs to rocker-bars, whereby two pockets are acted upon simultaneously by the knockers, ar-

ranging the knockers to act diagonally upon the pairs of pockets, connecting the pockets to annular heads having internal gears and bearings, and supporting the heads upon a counter-shaft having pinions engaging the gears, said pinions having hubs engaging the bearings, providing the annular heads with non-rotating heads having suitable packing and yieldingly pressed against the rotating annular heads by springs, and in various details of construction and arrangements of parts, as Will more fully appear by reference to the accompanying drawings, in which- Figure 1 is an end elevation of a device embod ying my invention; Fig. 2, a vertical section of the same on the line 2 2 of Fig. 1; Fi 3, a plan view of the jarring mechanism; Fig. 4, an enlarged detail of one section of the pockets shown in vertical section; Fig. 5, a

detail of one of the pockets shown in section on the line 5 5 of Fig. 4; Fig. 6,- a transverse section of a pocket taken on the line 6 6 of Fig. 5; Fig. 7, a detail showing the construc-' tion of a series of pockets, and Fig. 8 a detail showing the inner side of a non-rotating head.

Like letters refer to like parts in all the figures.

A A are two annular heads, preferably of cast-iron. These heads are provided with internal gears A, outwardly-projecting flanges surrounding the openings in the heads, and

internal bearings A in the plane of the pitchline of the gears A.

B is a counter-shaft provided with pinions B, the teeth of which pinions engage the gears A, and the hubs of the same engage the bearings A, and thus serve as rolls to support the heads, and also have a diameter the same as the pitch diameter of the pinions, whereby the pinions properly engage the gears.

O is a conveyor-shaft, which also serves as a driving-shaft.

O is a pinion on the shaft 0, engaging an internal gear D on the shaft B to rotate the latter.

D represents guides engaging the flanges on the heads A to cause the heads to rotate about a central fixed axis. The heads A arethus supported and rotated by the shaft B and driven equally by the respective pinions B.

Between the heads A are clamped the sections of radial filtering-pockets by means of bolts E. At each end of a section of pockets is a segment F, which segments are connected near their inner or concave edges by a series of crossbars F F, arranged equidistant from each other, the spaces between these. bars constituting the openings to the respective pockets. Opposite each alternate bar Fand extending radially from the outer or convex edge of the segments F are arms G, having recesses in their outer ends,in which recesses are adjustable cross-bars G, radially adjusted by screws G and provided with rounded outer edges engaging and supporting rocker-blocks H, to the respective ends of which blocks are attached the successive pairs of pockets, the outer ends of which pockets are provided with transverse strips I to support the same. The bars G are divided longitudinally at each end for a portion of their length to make them somewhat yielding to increase the vibration of the pockets and further reduce the noise.

The filtering-cloth, forming a section of pockets, consists of a single continuous strip of material, first arranged as shown in Fig. 7, being folded upon itself at intervals, so as to form the respective pockets J, leaving enough material J between each pocket to properly extend across the inner face of one of the bars F and sufficient material J at each end to cover the outer bars F of each section, and thus form a packing to insure a tight joint between the sections. To complete the respective pockets, the folded portions J are sewed at the edges, as shown in Fig. 6, thus forming a series of pockets connected by the portions J. The outer surfaces of these outer bars are in radial planes and abut against each other. I am thus enabled to make a whole section of pockets of one continuous strip of filtering material, which not only serves to form the pockets, but also forms packing between the sections and on the inner faces of the dividing-bars FF. lVhen assembled,theinterior of these sections engage flanges A on the heads A to adjust the sections concentric to the axis of the heads and form a tubular inner surface of the bars F F, having a surface composed of the filtering material, between which bars are the open mouths of the various pockets.

To prevent undue expansion or contraction of the pockets by the air-pressure, I provide radial stay-strips K at intervals, to which the sides of the pockets are secured.

To more effectually remove the adhering dust from the inside of the pockets, I provide sliding cleaners, consisting of suitable H- shaped wire frames L, to the opposite arms of which frame are attached small chains L, having sufficient slack to conform to any curvature of the sides of the pockets. These frames fit loosely and slidably in the pockets and traverse the same by gravity, being retained in the pockets by stops K. These cleaners shift from side to side of the pockets, traversing each side of the same alternately as the pockets revolve. These chains serve to remove the dust adhering to the interior of the pockets. For further means of discharging the dust from the pockets I provide knockers M, attached to an arm M, operated by a rock-shaft l\[",vibrated by an arm M, connected to a pivoted lever M, vibrated by pins D on the wheel D and engaging a suitable projection D on said lever. For varying the stroke of the knockers I provide an adjustable connection N between the arm M and lever M. To further adjust the force of the stroke of the knoeker, the rock-shaft M is provided with an arm N, engaged by a spring N, adjustable for tension by a screw N. These knockers engage the rocker-blocks and are arranged at different distances from the pivot of the shaft 3 ,w.hereby they act alternately on the pockets and at opposite ends of the same.

The openings in the annular heads A are closed by non-rotating heads 0, provided with packing 0 near the periphery, which packing engages the inner edge of the head A and the flange A and forms an air-tight joint. To press the heads 0 outward and maintain this joint, rods 0 extend between the heads 0 and are inserted and longitudinally movable in the bosses on the heads. A spring 0 on each rod engages a collar on the rod and a boss on the head and presses the heads 0 apart, and to adjust the tension of these springs while the machine is running set-screws 0, engaging the ends of the rods 0, are provided.

An air-pipe I conveys the dust-laden air to the machine, and to permit the free movement of the head 0 a longitudinally-yielding or elastic section P is provided, made of canvas or other yielding material and attached at its respective ends to the pipe P and head 0.

The conveyor-trough Q is provided with a convex top S, having a central opening to receive the dust discharged from the pockets, and is also provided with fixed ends Q, attached to the frame. The body of the trough is detached from these fixed ends and made vertically adjustable by means of screws Q, the joint between the heads Q and trough Q being closed by suitable packing 63. An exhaust-pipe R extends from the con veyertrough to any convenient exhaust means, preferably to the fan that drives the dust-laden air into the machine.

The operation of my device is as follows: The dust-laden air passes into the axis of the machine through the pipe P and yielding section P and under pressure enters all of the pockets except those over the conveyertrough, which latter are cut off by the eoncave S. This air escapes through the pores of the filtering material of the pockets, leaving the dust on the inner surface thereof. As the pockets revolve the chains L traverse the inner surface of the pockets by gravity and release the dust from the same. As the pockets come over the openings in the convex top of the eonveyer-trough this dust is discharged into the conveyer and removed from the machine thereby. To further effect this discharge of dust from the pockets, the knockers M vibrate the pockets and by the peculiar action are made quite effective. The knocker IIO farthest from the rock-shaft first engages the advancing end of the rocker-block at that side. This depresses one end of one pocket and raises the corresponding end of the opposite pocket, the rocker-block tilting on the supporting-bar G as a fulcrum. As the pockets move forward the other knocker comes into action at the other end of the pockets and acts at the opposite end of the other pocket of the pair. A sort of diagonal wave of vibration is thus set up in the material, which is very effective, and the knockers do not in a measure neutralize each other, as they would if arranged in line. The knockers also strike a yielding rocker-block and do not thus make as much noise as when striking directly over a supporting-bar. The pockets While thus subjected to the action of the knockers and over the opening in the convex top of the conveyer-trough are also subjected to an exhaust or reversed pressure of air due to exhausting the air from the con veyer-trough through the pipe B. This further facilitates the discharge of the dust from the. pockets.

The various adjustments of the bars G to adjust the tension of the pockets, of the conveyer-trough to maintain a close contact of its convex surface S with the bars F F, and of the heads 0 to maintain a tight joint around the same are all easily made while the machine is running by turning the respective screws for these purposes.
