Patented Oct. 15, 1929 UNITED STATES PATENT OFFICE TITUS RUSSELL, OF HOLLAND, MICHIGAN, ASSIGNOR '10 HOLLAND FURNACE COMr PANY, 0F HOLLAND, MICHIGAN APPARATUS FOR FURNACECLEANING Application filed August 24, 1925.v Serial No. 52,174.

This invention relates to improved apparatus for furnace cleaning. It is adapted to scribed in United States Letters Patent No. 1,589,986 and 1,589,987 issued June 22, 1926.

The object of the invention is to provide a compact and eificient pneumatic means for cleaning a furnace that can be readily transported on a truck and-collect the dbris, dust and dirt in an effective manner.

Objects pertaining to details and econo-Z inies of construction and operation of my invention will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means lowing specification. The invention is clearly defined and pointed out in the claim.

A structure which is a preferred embodiment of my invention is clearly illustrated in parts appearing in I! the accompanying drawing forming a part of this application, in which:

Fig. 1 is a diagrammatic view of my improved structure organized and connected to clean a furnace.

Fig. 2 is a plan view of the cleaner structure appearing in Fig. 1.

Fig. 3 is an enlarged detail rear view of the Fig. 4 is a detail sectional view of the fan taken on a line 4.-4 of Figs. 2 and 3.

In the drawing similar reference numerals indicate similar parts in all of the views.

I will refer to the difierent parts by their numerals of reference. 1 is a hot air furnace, 2 are the hot air pipes leading therefrom. 3

is the smoke pipe. 4: is the fuel feed for the furnace. 5 is the suction fan. 6 is a suction pipe connected to the intake of the fan and to a nozzle 7 which connects to the frame of the door 4. 8 is a diagrammatic view of a gasoline engine for driving the fan. 9 is a dust of the dust collector with an opening at the center. A dust collector described in the folthe top of this collector so that it can be inflated upwardly and collect any fine dust that may be discharged from the cyclone dust collector and effectively prevents the passage of any dust whatever into the atmosphere. The dust bag 94 collapses as indicated in Fig. 1 when the machine is not in operation.

The method of operating my improved structure is perfectly clear. The suction pipe with its nozzle 7 is connected to the door frame of the furnace or other outlet. The fan is operated by driving the motor and sucks all dbris from the interior of the furnace, delivering it into the dust collector where the same is separated from the air which passes up and is further filtered by the dust bag. v I The device is adapted also to connect to any I aperture in a furnace casing and by that means a convenient elfective apparatus for carrying on the method of cleaning furnaces and furnace casings, made the subject matter I desire to claim the same especially for that purpose herein.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

' A portable suction fan, a suction tube connected to the intake thereof, a portable dust collector of the cyclone type associated with the said fan and connected thereto to receive the dbris therefrom and deliver air upwardly at the center, and a balloon-shaped dust bag secured centrally to the top' of said dust collector to receive the discharged air and above the cyclone dust collector and disposed to collapse on the top thereof, all coacting as specified;

In witness whereof I have hereunto set my hand.
