DUST-CATCHEB FOR AIR-PIPES.

Specification of Letters Patent.

Patented Sept. 22,1914.

Application filed February 5, 1914. Serial No. 816,759.

which th'e'following is a full, clear, and erract description.

' My invention relates to a dust catcher especially adapted to be interposed in an air conductor pipe of a hot air furnace at any point between the furnace and register. An object of the invention is to provide an efiicient' dust-catcher of the indicated character, of simple construction and adapted to be conveniently placed in position-in a way to bereadily accessible for the changing of the dust-catching material when desired.

The invention will be particularly explained in the specific description following.

Reference is to behad to the accompany i'ng drawings forming a part of this speci fication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a dust catcher embodying my invention, showing the same applied; Fig. 2 is a perspective view of the drum or outer casing of the device; .Fig. 3 is a perspective view of a removable holder adapted to be receivedwithin the drum and to hold cotton or other dustcatching material; Fig. 4 is a cross section on the line 4i of Fig. 1, on a larger scale; and Fig-5 is avert-ical section on the line 5-5 of Fig. 4.

In constructing a practical embodiment of my invention a drum is provided, adapted to be interposed in an air conductor pipe, the drum being of any desired contour, here shown as of general globular form in the body 10 thereof. The said body is provided with registering necks 11 adapted to fit stove pipe sections A, leading from any furnace P). 'A side door 12 is provided, hinged at one side to thebody 10, as at 12"; the said door forming approximately one half the body. Any suitable fastener may be provided for the door, as for ins ance, a pivoted latch hook 13 adapted to engage a pin 1% on the fixed portion of the body.

\Yithin the drum is a separate. removable holder for the (lib t-catch ng mater'al. Said holder comprises an outer bulging wall 15 conforming in general to the interior of the drum and having inlet and outlet ends for the air, in register with the necks 11 of the drum. VVit-hin the outer walls 15 of the holder a cone 16 is providedQthebase of the cone being connected with the bulging wall adjacent to the outlet end thereof and the apex of the cone being disposed in the direction of the opposite inlet end of the holder. The wall loand cone .16 are formed of reticulated material; that is to say, any suitable material having numerous openings therethrough, wire mesh being preferably employed. Both the outer wall and the cone of the holder are adapted to contain cotton or equivalent dust-catching material. In the cxampleshown, a layer 17 of such material is applied at the exterior of the wall 1.1, between thesazne and the outer drum, so that the said material is exposed through the meshes of the holder. The dust-catching material 18 employed in connection with the cone 30. may be placed 'within thelatter, as indicated-clearly in Figs. l and 5, leaving the base of the cone without the. i as to atford an outlet'for the {-110 through the cone adjacent to the base.

By the described'construction when the holder is in pos tion in the drum, the air entering the inlet end of the drum will pass to the interior of the outer wall 15 and will be deflected by the cone so that the air will contact with the cone and with theopposed inner surface of the wall 1 in passing toward the .=utlet end at the base of the cone. the cotton or ctlrer material serving to catch the particles of dust.

It willbe :QQII that the holder is removable laterally from the drum by on ing the side doc: or hinged section 12 of the drum.

t will be observed also that the registering necks 11 are carried by the body 10 and. that the door or hinged side 12 is formed with corresponding concave recesses 12 to conform to said necks.

Having thus described my invention. I claim as new, and desire to secure by Letters Patch:

1. A 2st catcher. comprising an outer drum having necks at opposite ends to fit stove pipe sections and having a bulging body provided with a side door: and an inner, hollow holder for dust catching material said holder being formed with irfet and outlet ends registering \viih the net-.1) of the. drum and having an outer bulging wall conforming generally-to the body of the drum, anda cone Within the said wall and united to the latter at the base of the cone adjacent to the outlet end 'of.the holder, the apex of the cone being disposed in thedireciion of the opposite open end of the holder.-

A dust catcher, comprising an outer drum formed at the'opposite' ends to fit stove pipe sections and having an enlarged body provided with a side door; and a rem'givable hollow holder of reticulated 1naterialfivithin said drum, said holder comprising .anouter bulging wall, and a cone Within the said wall, said wall cor-forming generally to the drum body and having an inlet end and an outlet end adjacent to the ends of the drum, the reticulated conevbeing united at its base to the reticulated Wall adjacent to the outlet end, the apex of the cone being disposed in thedirectionof the inlet end, and a dust-catching material. held by said cone and Wall.

Y ,3. A dust catcher, comprising an outer apex of the cone being disposed in the'direc- 1 tion of the inlet end, and dust catching Inateria-l held by said wall and cone.

ah A dust collector comprising a drum having inlet and outlet necks at opposite ends. to fit pipesections and having a bodyof. increased diameter between the necks, an inner hollow holder for dust catching material, said holder'being' formed with inlet and outlet 'ends registering with the necks of the drum, and having an outer foraminous wall of increased diameter between the said inlets and outlets, to conform generally to the body'of the drum, the holder having also a foraminous cone supported within and spaced from said wall, the tapering end of the cone being disposed in the direction of the inlet of the holder:

dust catching material in said. cone, and

dust-catching material between the foraminous Wall andth drum.

'5. In a dust ca cher, a dust-collecting device eonsisting of an outer wall of foraminous material, and an axially disposed inner cone of foraminous material connecting at its base with the adjacent end of the outer Wall, and dust-collecting material on said cone and the wall.'

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
