DUST-COLLECTOR. 978,739. Specification of Letters Patent. Patented Dec. 13, Application filed February 5, 1910, Serial No. 542,223. To all whom it may concern: Be it known that we, MILTON O. GRIs of the casing. 1. Within the annular groove WOLD and TFIEODORE BRIEGEL, citizens of the 4 is disposed suitable packing 5, whereby the United States, residing at Rock Island, in lid 3 may have an air tight union with the the county of Rock Island and State of casing 1. The casing 1 is provided upon its Illinois, have invented certain new and use Outer surface and near the upper end there ful Improvements in Dust-Collectors, of of, with diametrically arranged ears 6, which the following is a specification. which have pivotally mounted thereon as at Our invention relates to dust-collectors 7, Screw-threaded pins 8, which in turn O and more particularly to a dust-collector to carry thumb-nuts. 9. The pins 8 are, ar be interposed between a suitable suction ranged to be inserted within diametrically pump and a pneumatic renovating-tool, such disposed slots 10 formed upon the lid 3, and as is used for cleaning carpets, rugs, and the the thumb-nuts 9 may then be screwed up to clamp the lid 3 upon the casing 1. It is like. - 5 An important object of our invention is to obvious that the thumb-nuts 9 may be freed provide a dust-collector, which is compactin from engagement. with the lid 3, whereby its construction and having parts which are said lid may be readily removed from the readily removable for the purpose of cleans casing 1.

It will thus be seen that an annular space made of sheet-metal. The casing is shown 18 is provided between the receptacles 16 as being cylindrical and having its lower and 12. The inverted receptacle 16 is per end closed by means of a bottom 2. The forated adjacent its lower open end as at 19, upper end of the casing 1 is formed open below the water level of receptacle 12, for 50 and is normally covered by a removable cir establishing communication with the re cular lid 3, which is provided upon its under ceptacle 12. The receptacles 12 and 16 are side near its periphery, with an annular provided upon their inner and outer sides groove 4 for the reception of the upper end. respectively with annular ribs 19, which are in horizontal alinement and detachably
