This'invention' relates to dust collectors and particularly to dust collecting attachments for rotary brushes.

F or cleaning garments and for various is other purposes, light portable rotary brushes driven through suitable flexible shafts are now in "use. The lint and dust by such brushes has not, however, been heretofore adequately'taken care of, and has been allowed to settle about thepremises onwhich the brush is usedor has required use of the brush adjacent to an outlet from such premises together with one or more fansfo'r discharging such dust and lint through said opening.

It is an object-0f this invention to provide a light and inexpensive dust collecting attachment fora brush of the aforesaid character, keeping the air inthe premises on which the brush is used clean and sanitary. V

Anotherobject is'to provide a light fabric 7 receptacle fordust removed from a garment or the like by a rotary brush, and to hold said receptacle expanded in use by a frame formed of wire or thelike, having a'suitable provi-' sion for its attachment to and detachment from a casing partially enclosing saidbrush whereby the brush is adapted to deliver the dust and lint from the garment through said casing into said receiver. I j

"Still another object is to provide a'plate formed of sheet metal, or the like, within said fabric receiver to take the impact of the dust or lint discharging from the brush, said plate being preferably permanently carried It isalso an object of this invention to provide a'thumb piece rigidly connected-to the casing offthe brush, and a handle member tthrough which a drive shaft extendsto the brush, said thumb piece facilitating a com plete control ofthe brush by the operators hand whichgripssaid handle. 7 V v These and various other objects the invenf tion attains by the construction hereinafter described and illustrated in the accompanying drawings herein.

As a preferred means forquickly securing said frame to the fitting 9 or disconnectingit therefrom-the support-' edend of saidframe comprises a split ring- 11-, one end-of which forms an 'e'yejl2 through which the other end of said ring is passed, as] if Q indicated at 18.

While thedevice is primarily designed for cleaning 7 articles of-wearingiapparelit is to be-understood that it is also applicable for removing su' orted end thereof and servin to initiall receive the impact of dust and lint which are discharged by the brush 1 into the receiver 22.

The provision of the plate 1 6: prevents any dislodgedparticles of dust or dirt from being thrown" violently against'th'e fabric wall, and consequently adheringthereto. i

It is to be noted that onlya slight clearance space is provided between the brush of the casingel so that the brush acts largely after 7 the manner'of a fan tending to draw the dirt from the garment by suction, as well as by actual contact, and throwing such dirt, lint, etc., forcibly into the receiver.

What weclaim is: p

1. The combination with a rotary brush, of a casing formed with an opening through which a- 'peripheral working portion of the brush projects, and further formed with a peripheral outlet for dust and lint, a dust receiver detachably connected to said outlet and projecting from the casing substantially transversely to the brush axis, a handle laterally'extending from said casing, a drive shaft for said brushextjendi'ng through saidhandle and a thumb piece mounted upon-said handle adjacent to said casing andprojecting from saidhandle substantially, opposite- 1 lyto the dust receiver, whereby the excess of weight carried by the casing at its dust receiver side may-be counteractedby pressureapplied to i said finger .piece.
