RALPH H. BOURNE AND AUBREY J. GRINDLE, OI CHICAGO, ILLINOIS, ASSIGNORS TO GRINDLE FUEL EQUIPMENT COMPANY, OF HARVEY, ILLINOIS, A CORPORATION or ILLINOIS.
' DUST COLLECTOR.
Application iiled November 22, 1824. Serial No. 1,482. i
To all whom it may concern:
Be it known that we, RALPH H. BOURKE and AUBREY J. GRINDLE, citizens of the United States, residing, respectively, at Chicago and Chicago, in the county of Cook and State. of Illinois, have invented a certain new and useful Im rovement in Dust Collectors, ofv which the ollowing is a specification.
This invention relates to dust collectors conventionally used in and adjacent to factories ofvarious sorts employing machines throwing into the air a large amount of dust and dirt, which would be injurious to the workmen and the general public were the dust and dirt laden air allowed to circulate generally prior to the removal of such dust and dirt from the air. The invention consists in a novel form of mechanism for producing this well known, desired result; which can be very easily and cheaply made; which is satisfactory in use and is not readily liable to get out of order.
More particularly the invention consists in numerous features and details of construction which will be hereafter more fully set forth in the specification and claims.
Referring to the drawings in which like numerals designate the same parts throughout the several views:
Figure 1 is a side elevation, largely in section, with certain parts broken away, illustrating this invention in its preferred form.
Figure 2 is a sectional plan view on the line 2-2 of Figure 1.
The preferred form of construction of Figure 1 employs an external case 10 in the form of a fulcrum of an upwardlypointed cone, the upper end of which is closed by a generally horizontal cover 12 perforated at its center to interfit with an upwardly extending pipe or passage 14 for l 20 through which, as shown, the dust and dirt may fall in a pile below the device, or to which a conveyer pipe, not entering into this invention and therefore not shown, may be attached for conducting dust and dirt to a distant point.
Concentrically mounted with reference to the central axis of case 10 and with reference to each other and located inside said case are two spaced cylinders 22 and 24 etween cylinders 22 and 24 is a spiral partition 26 forming in connection with said concentric cylinders 22 and 24 a spiral air passageway leading from an opening 28, near the top of cylinder 24 approximately twice around the cylinder 22 to finally discharge into the interior 30 of case 10-18 at the lower ends of cylinders 22 and 24. The opening 28 is constantly supplied with air under pressure through a suitable pipe 32 assing through the exterior case wall 10, suc 1 air under pressure being pumped into the pipe 32 by any suitable means as, for instance, a conventional fan 34 not entering specifically into this invention and therefore not detailed. The pipe 32 is so positioned with reference to opening 28, that laden air delivered by said ipe 32 impinges tangentially on the ins1de surface of cylinder 24, thus causing said dust laden air to traverse the screw shaped passage defined by spiral partition 26 and in close proximity to the interior surface of said cylinder 24 with the result that the dust and dirt in said air readily finds it way to vertically disposed slotted openings 36 in the surface of cylinder 24. The ready passage of dirt and dust through case openings 36 is assisted by the presence of stamped inwardly pressed guide plates 38 formed at each opening 36 in the wall of cylinder 24. These plates 38 are formed in quite obvious manner in the operation of cutting perforations 36 in the wall of cylinder 24.
In order to assist in forcing the dust laden air to the interior circumference of cylinder 24, the outer surface of cylinder 22 is provided with a multiplicity of vertically disposed wings 40 so placed as to direct'air striking them toward the interior circumference of cylinder 24. k
In the operation of the mechanism ofthis invention, dust laden air is continuously delivered by fan 34 through pipe 32 into the spiral passage between cylinders 22 and 24 and along the interior surface of cylinder 24. As the dust laden air passes around the interior of the cylinder, the heavier dirt and dust particles engage sooner or later one of the guide plates 38 and pass through slotted passages 36 into the space 42 between mein bers and 24. As soon as the dust anddirt reaches this space, it is no longer propelled by air and drops by gravity in the general interior of s ace 30 of the machine onto the interior sur ace of cone 18 down which said latter outward passage of cleaned air may be-produced either by initial pressure in pipe 32 or by suction applied by means not entering into the invention and therefore not shown, applied beyond the figure to pipe 14.
In actual practice results not heretofore experienced with commercial dust collectors have been attained by the mechanism of this invention.
Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
' 1. In mechanism of the class described, in combination, an outer case, a air of concentric spaced cylinders inside t e outer case connected together by a spiral partition forming a spiral passage extending from top to bottom of said cylinders, there being in the outer of said concentric cylinders a multiplicity of vertically disposed elon ted perforations opening into said spira passage,
