UNITED STATES PATENT OFFICE CHARLES R. KNICKERBOOKER, OF'JAOKSON, MICHIGAN, ASSIGNOR To THE KNIOKERBOOKER COMPANY, or SAME PLACE.
DUST-COLLECTOR.
sPncrr'rcATIoN forming part of Letters Patent No. 382,614, dated Ma a, 1888.
Application filed March 1,1888. Serial No. 265,848. (No modeLl T or whom it may concern:
Be it known that 1, CHARLES R. KNICKER- BOOKER, of Jackson, in the county of Jackson and State of Michigan, haveinvented new and useful Improvements in Dust-Collectors, of
which the following is a specification.
This invention relates to that class of dustcollectors which are employed in fiouringmills, grain-elevators or store-houses, woodro working establishments," and in various other factories for separating flour-dust, chaff, straw,
sawdust, shavings, and other solid matter from the air in which this matter is suspended. In
all of these machines the object is to discharge the solid matter from the dust-collector mingled with as little air as possible, while the air from which the solid matter has been separated'is permitted to escape in a different direction.
The object of this invention is to obtain a close separation of the dust from the air by smaller machines than heretofore employed, thereby avoiding the necessity heretofore existing of constructing large unwieldy machines, which are difficult to ship and locate when the -volume of dust-laden air delivered to the machine is considerable-as, for instance, when one dust-collector receives the air from a number of grain-separators'or other machines.
My invention consists, to that end, in combining a preliminary dust-collector, in which a portion of the air is separated from the dust, with a subsequent dust-collector which is connected with the dust-discharge of the preliminary dust-collector, and which efi'ects a further separation of the air from the dust, as will be hereinafter fully described, and pointed out in the claims.
In the accompanying drawings, -Fi gu re 1 is a sectional elevation of a simple form of my improved dust-collector. Fig. 2 is a horizontal section in line 00 00, Fig. 1. Fig. 3 is a similar view showing an auxiliary fan interposed between the preliminary and subsequent dustcollectors.
Like letters of reference refer to like parts in the several figures.
A represents a fan,which receives the dustladen air through the induction-spout a, and 50 delivers the same to the preliminary dust-collect'or' B, which is connected with the'blast' spout of the fan A. This preliminary dustcollector is preferably composed of a tube, 0, having in its top an air-escape opening, (1, at its end a contracted dust-discharge, e, and de- 5 5 fleeting plates ff extending into the tube towardits discharge end, as more fully described in Letters Patent of the United States, No. 375,983, dated January 3, 1888. This preliminary dnst-collector effects a separation of part of the air from the dust or solid matter, the latter being concentrated into an air-current. of smaller volume passing through the dischargeconduit 6, while the separated air escapes through the escape-opening d, which may be surmounted by a pipe, (1, as shown.
G represents the subsequent dust-collector, which is connected with the dust-discharge conduit 6 of the preliminary dust-collector, and receives the dust-laden air-current therefrom. This subsequent dust-collector is pref-,. erably of the type in which centrifugal-force is employed in effecting the separation.
As represented in Figs. 1 and 2, the dustdischarge conduit e of the preliminary dust- T collector enters the conical separatingchamher 9 of the subsequent dust-collector tangentially, whereby the dust-laden air is caused to assume a whirling motion in this separatingchamber. This subsequent dust-collector et'- fectsa further separation of the air from the dust, the latter being discharged through the opening h at the small end of the conical separatingchamber, whilethe air is discharged through the opening 12 at the large end of the separating-chamber. As this type of machine is very effective in making a close separation of the dust from the air, I prefer to use it for working of the subsequent dustcollector, while it at the same time improves the opera tion of the preliminary dust-collector by reducing the back pressure to a minimum.
In fitting up a grain storehouse, mill, or other establishment each grain-separator, or other machine in which an air-separation is efi'ected, may be provided with a separate preliminary dust collector, and the dust-discharge conduits of the same may be united so as to discharge into a single subsequent dust'collector, which extracts from the concentrated dustladen air-current the remainder of the separable volume of air and discharges the solid matter into a convenient receptacle-for instance, into the boiler'room, where it is used as fuel. Each of these dust-collectors can be of comparatively small size, so that they can be conveniently shipped and put in place for operation.
I prefer, for the preliminary separation, a dust-collector in which the separation of the dust from the air is effected by deflection and projection, and for the subsequent separation a dust-collector in which centrifugal force is employed; but I do not wish to limit myself to this order of arrangement.
Two or more preliminary dustcollectors, in which the separation of the dust from the air is effected by deflection and projection, might be employed, in which a certain percentage of the air would be separated from the dust in its passage from one dust-collector to the other, and the same type of dust-collector might be used in efiecting the subsequent or final separation.
When the solid matter which is delivered into the tapering separating-chamber of the subsequent dust-collector is so heavy or bulky that centrifugal force prevents it from going down to the dust-discharge opening-as, for instance, blocks, shavings, ,&c.this separating-chamber is provided on its inner side with a spiral flange, as represented in Fig. 3, or is otherwise constructed to compel the solid matter to pass to the dust-discharge opening.
By combining the two successive dust-collectors in the manner herein claimedthat is to say, so that the dustexit of the preliminary dust-collector discharges into the inletspout of the subsequent dust-collector-a large portion of the air is removed by the preliminary dust-collector, and the Volume of air which reaches the subsequent dust-collector with the dust is greatly reduced, thereby enabling the final separation of the dust from the air to be effected closely without creating an objectionable back pressure. a By this means the volume of air is reduced before the final separation is effected, while in the constructions heretofore used the volume of dust or solid matter was gradually reduced.
I do not claim as my invention the construction of either the preliminary or the subsequent dust-collector herein described and shown, both of these machines having been well known prior to my invention.
I claim as my invention- 1. The combination, with a preliminary separating-chamber provided with an inlet for the dust-laden air, an exit for the separated air, and an exit for the reduced volume of air containing the dust, of a subsequent separatingchamber having its inlet connected with the exit through which the reduced volume of air containing the dust issues from the preliminary chamber, and provided with an exit for the separated air and an exit for the dust, substantially as set forth.
2. The combination, with a preliminary separating chamber provided with an inlet for the dust-laden air, an exit for the separated air, and an exit for the reduced volume of air containing the dust, of a subsequent separating-chamber having an exit for the separated air and an exit for the dust, a conduit connecting the exit of the preliminary separating-chamber for the reduced volume of air containing the dust with the inlet of the subsequent separating chamber, and a fan arranged in said conduit, substantially as set forth.
3. The combination, with a preliminary dust-separating chamber provided with an inlet for the dust-laden air, an exit for the separated air, and an exit for the reduced volume of air containing the dust, of a circular subsequent separatingchamber having an exit for the separated air, an exit for the dust, and a tangential inlet-spout connected with the exit through which the reduced volume of air containing the dust issues from the preliminary separating-chamber, substantially as set forth.
WVitncss my hand this 27th day of February, 1888.
CHARLES R. KNIOKERBOOKER.
