. AMON T. NOE, OF PARNASSUS, PENNSYLVANIA, ASSIGNOR TO ELECTRIC RENOVATOR MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA.

DUST-COLLECTOR.

To all whom it may concern:

Be it known that I, AMoN T. N OE, acitizen of the United States, residingat l arnassus, in the county of Westm'oreland and State of Pennsylvania, have invented certain new and useful Improvements in Dust-Collectors, of which the following isa specification.

My invention relates to'dust collectors, and more articularly to devices of this character esigned for use in connection with pneumatic renovating apparatus, such as is commonly employed in house cleaning.

The present invention relates to certain improvements inthe type of dust collector illustrated in my prior application Serial Number 393,936, filed September 21st, 1907.

The primary object of the invention is to provide a dust collector which shall be so constructed as to effectively prevent the escape of dust therefrom but from which ac-- cumulations of dust may be quickly and readily removed. A further object of the invention is to rovide im roved means for delivering the ust laden air into the collector.

With the above and other objects in view my invention consists in the construction and arrangement hereinafter described and illustrated in the accompanying drawings in which- Figure 1 is'a central longitudinal section through my improved dust collector, complete. Fig. 2 is a pers ective' view of one of the supporting frames ereinafter described. Fig. 3 1s a side elevation of the removable end member of the. dust collector casing. Fig. 4 is a central longitudinal section through one of the parts hereinafter described.

Referring to the drawings in detail my improved dust collector comprises a casing 1,

preferably cylindrical, the'walls of which are foraminous and which may consist either of Wire gauze or as shown of perforated sheet metal. The upper endof the casing 1 is closed by means of an end plate 2 having a I Specification of Letters Patent.

responding lugs and are screw threaded at one end to receive thumb nuts 8 by means of which the two ends of the casing are secured together.

The end plate 2 is provided with a series of internally projecting, annular, concentric ribs 9, the urpose of which will be hereinafter described. Secured to the ring 5 and projecting upwardly and inwardly therefrom are a plurality of arms 12 connected at their upper end by a smaller ring 11. The arms 12 are provided on their upper surface with a series of notches or steps 13, the purpose of which will now be described. Restmg in these notches are a plurality of concentrically arranged supporting frames oneinner frame being the shortest, but the top of all of the frames lying substantially'in the same plane and somedistance below the end plate 2.

Alternating with the frames above 'described is a second set or series of similar frames com rising upper and lower rings '15 connected y brace rods 15*. The upper rings 15 are held in position by means of the annular ribs 9 on the end late 2.

4 Secured to one end of .t e casing as at 17 is one end'of a continuous web or fabric 16,

which fabric is preferably of closely woven though orous material, and is 100 ed back and fort around theends of the a ove described alternating frames. As will be seen from Fig. 1 this web orfabric asses over the tops of the rings 10 and un er the bottom edges of, the rings 15'thereby forming a support for the latter and holding them up in such position that their upper ends abut against the top late 2. The inner end of the fabric is secured as at 18, to the flange 3 depending from the top plate, and rovided with a groove to accommodate a suitable tie wire or the like. It will therefore be seen that the two sets of frames cause the tubular web or fabric to assume such shape as to form a series of annular concentric chambers of tapering form, having porous walls some of which, as 23, open upward, while the others,

a Et -wiH-be obsessed heweversthati which open: uphwardahave he eommmiieehem withthereby. The result of the em loyment of these floating frames is that y removing the lower end ring of the-casing, the entire dust collecting structure can be readily removed and disconnected, whenever it is desired to clean or renew the same.

The lower end of the casing 1 is closed by means of the removable bowl-shaped bottom 19 fitted with looking cams 2O cooperating with projections 20 formed on the ring 5. Projecting upwardly from the center of this bottom 19, and preferably formed integral therewith is a 0st 21 which when the bottom is in its osition in the casing projects well up into t e innermost chamber of the series. At its upper end this post carries a comcal spreader 22 or baflie plate hereinafter referred to. Also secured to the flange 3 and depending below the same is an annular flap 25 formed of some flexible material, which flap aids in preventing the leakage of dust past the flange 3. Fitted within the, opening which the flange 3 surrounds is one end of a conduit 26, the other end of which is adapted to be connected with the discharge from any suitable fan or pump and thus serves to deliver dust laden air into the casing. It will be seen therefore that the dust laden air entering the innermost chamber through the conduit 26 impinges against the spreader 22 at the lower end .of this chamber and is thereby deflected and caused to spread through the bottom part of the casing from which it difiuses upward into the annular chambers 24, the dust being retained by the walls of fabric and the air filtering through the same and escaping through the outer walls of the casing. It is to be noted that the dust is collected in the chambers which open downwardly the other chambers being entirely closed. This construction results in the dust all accumulating on one side of the fabric and in one end of the dust collector. Itwill, therefore, be apparent that by ently tapping or jarring the casin all of t e entrapped dust will fall into t e bowl-shaped bottom 19 which may then be removed and em tied.

he end plate 2 is not rigidly secured to the casing 1.-but can slide freely therein, and hence, by screwing up the thumb nuts 8 and thus drawin in theend plate the lower ends of the partitlons 15 will be forced against the loops of the fabric in which they rest and this putsend. maintain thefabrie under terms n.
