DUST-COLLECTOR.

SPECIFICATION forming part of Letters Patent No. 655,635, dated August 7, 1900. V Application filed .Tuly 1,1899. Serial No. 722,570. (No model.)

To all whom it may concorre.' l

Be it known that I, ORVILLE M. Monsn, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Dust-Collectors,of which the following is a specification, reference being had therein to the ,accompanying drawings.

The invention consists in the construction of a dustoollector embodying` a chamber having an air-inlet for the dust-laden air and exit from the chamber, across which are arranged brushes and means for jarring or agitating the brushes and for sweeping up the collected dust.

The invention further consists in combining such a dust-collector with an initial dust collector or separator which Will collect all but the fine dust and use my improved dustcollector as an attachment thereto for the purpose of collecting this fine dust.

The invention further consists in the construction, arrangement, and combination of the various parts, as more fully hereinafter described, and, pointed out in the claims.

In the drawings, Figure l is a sectional perspective view showing myimproved dustcollector attached to a dust-separator or dustcollector of the general type shown in my previous patent, No. 403,362, of May 14, 1889. Fig. 2 is a oross-section through the upper part of Fig. l. Fig. 3 is a detail section illustrating the construction of the vibrating means for the brush or broom sections.

I have shown my dust-collector as circular in form and comprising the heads A and B. In this case the head B forms the top of the initial dust-collector, the body of which is palpable dust, so light as not to be affected by the centrifugal action in such momentum dustcollector, and it is to collect the dust in the air passing through this air-enit that I- have shown my improved dust-collector applied.

The head A, I have shown secured to a shaft G, which is journaled in suitable bearings in the top of the momentum dust-collector. This is driven by any suitable meansas, for instance, by a Worm-gearH on a shaft I, meshing with a worm-WheelJ on the upper end of the shaft G. Secured to the edge of the plat-e or end A are the brushes K, so ar= ranged as to cover the exit from the chamber Within. In this construction the brushes K form the entire circumferential Wall of the dust-collector. These brushes are preferably formed of a brush-head L, having the pins M slidingly secured through bearings in the top A, with springs N adapted to hold the heads normally in their upper position. These sections are preferably of such length as to extend between the radial plates or dividing-Wings O, Which are secured to the under side of the head A and extend down into close proximity to the head B, thus dividing the dust-chamberinto a series of sectors, as plainly shown in Fig. 2.

It Will be obvious from this description that my dust-collector, as herein shown, consists of a circular chamber, the dust-laden air being delivered thereinto from the aperture F, and that the air may find an exit through that Wall thereof which is formed by the brush.

I have found by practical experiment that such dust as comes from the eye of the molnentum dust-collector is of such a nature that upon striking an object in its path it Will adhere thereto, very much as Wet snow ad' heres to the sides of trees when blown by the wind. I therefore find that with brushes of, for instance, broom-corn or similar material arranged as described in relation to the dustchamber if the dust-laden air is blown therethrough the dust will adhere to the brush, While the air Will iind a practically-'unobstructed passage throughthe brush.

It will be observed that the 'brush forms the Wall of the dust-collector and that there is a free and. unobstructed exit for the air through that wall and no perforated cloth or Wall-through which the air must subsequently be passed and which would make a back pressure and to which any small particles of dust which might pass through the brushes would adhere. I Iind with such a device that the air from the eye of such a momentum dust-collector after passing through my improved dust-collector may be discharged with impunity into the mill.

The radial wings or blades O divide the dust-chamber into a series of compartments, as before described, each one of which extends from the air-inlet section to the brushes at the other end.

In order to clean the brushes of the accu mulated dust, I arrange at one point a cover P for a section of the air-inlet passage F, as plainly shown in Fig. 2, this plate being sufficiently long or Wide to cut off from the air inlet opening an entire section of the dustchamber. While thus cut off, there is of course no air circulation through that chamber and there is formed what I call a deadair chamber therein. While the air circulation is thus shut off or the dead-air chamber is formed I knock or shake the brushes by any suitable means and arrange beneath the same a discharge-spout Q, into which the dust therefrom will pass. The preferable means which I employ for cleaning the brushes of dust consist of a toothed cam R, secured above the machine, which is adapted to be engaged by a pin S, which projects from the brush-head, the brush-head being through the head A in the casing in the travel thereof, as shown at the left hand in Fig. 2 and which is illustrated more particularly in Fig. 3.

It will be seen from this description that through the greater part of the travel the dust from the eye of the momentum dust-collector will rise into myimproved dust-collector and pass freely through the brush-walls thereof Without any materialimpeding of the air-,current or back pressure on the device and that at one or more points of the operation the air circulation is shut cti", and while thus shut oit the brushes are cleaned.

I preferably make lthe plate Padjustable by any suitable means-such for instance, as theradial slots a, in which clamping-screws may be engaged to clamp the cover or plate in the desired position. This I preferably arrange so that there may be a slot T leading into .the

eye of the momentum dust-collector at such points therein that there is a draft from the dust-chamber, so that at the time the brushes are shaken or vibrated whatever air pressure or circulation there is is inward, and thereby I prevent any dust from being discharged into the room While the brushes are being cleaned.

I have shown and I preferably employ a iange or strip U around the edge of the head B, extending a slight distance up the brushbody to insure a tight joint at the lower or free end of the brushes.

That I claim as my invention is 1. A dust-'collector comprising two circular heads, and a cireumferentiallyarranged brush, a series of imperforate radial division- Walls forming a series of chambers, an air-inlet common to all the chambers at the center of one head, means for shutting off the chambers successively, and means for vibrating the brush of the shut-off chamber.

2., A dust-collecting device comprisingamomentum dust-collectorhavin g a tapering body and an apertured head, of a dust-eol1ectorap plied thereto comprising the head A, radial imperforate division-Walls secured thereto, means for rotating the same, a brush formed in sections extending between the edges ofthe head A and the head of the momentum dustcollector, means for vibrating sections of the brushes, and a dust-spout over which the brushes are vibrated.

3. Adust-collectingdevice ccmprisingamomentum dust-collector having a taperingcasing and an apertured head B, of a dust-collector applied to the head and consisting ot' the head A complementary to the head B, means for rotating the head, a series of circumferentiallyarranged brushes secured to the head A and extending to the head B, a series of radial apertures dividing the space between the head into a series of chambers, a cut-off between the opening in the headB and each ofthe chambers successively during the rotation thereof, and means for vibrating the brush during the eut-off period of such chamber.

4.-. A dust-collecting device comprisingamomentum dust-collector, consisting of a casing having an apertured head and a tangential air-inlet, of a dustcollector applied to the aperture in the head and comprising a brush, arranged over the exit therefrom, means for shutting oft communication between the exitopening and the chamber within the casing and connecting it with a reverse-operating draft, and means for vibrating the brush during such shut-ofi' period.

5. A dust-collecting device comprising a tapering easing, a tangential inlet for the dustladen air, a dust-outlet at the small end, an imperforate top having a central aperture for the purified air, an imperforate head above the top of the dust-collector forming a chamber between the two and brushes extending between the head and top through which the air from the chamber last referred to must pass in its exit and means for vibrating or shaking said brushes intermittently,

In testimony whereof I affix my signature in presence of two witnesses.
