N. C. FETTERS AN-D C R.) RICHARDS.
DUST COLLECTOR. APPLICATION HLED Am Patented Dec. 28, 1920.l
UNlTED 'STATES PATENT OFFICE.
NORMAN CRAIG FETTQERS AND CHARLES RAYMOND RICHARDS, OF ALLIANCE, OHIC.
DUST-COLLECTOR.
Application filed April 10,
T o all 'whom it may concern:
Be it known that we, NORMAN C. FETTERS and CHARLES R. RICHARDS, citizens of the United States and residents of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Dust-Collectors; and we do hereby declare the following to be a full, clear, and exact description of the invention, s uch as will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to an improvement in dust collectors adapted particularly for use in connection with electric sweepers.-
In our application for Patent Serial N o. 351,565 filed January 15th, 1920, the exit end of the duct through which the dust laden air passes terminates under water so that the air and dustand dirt are projected upwardly through the water and are deflected into a sediment chamber in which the dust and dirt are collected.
In this invention the air duct terminates within the sediment chamber and above the water and the dust laden air is saturated with water as it leaves the duct, the Water beiner forced up and sprayed over the escaping dust by a pump actuated by the suction motor of the sweeper.
1n the accompanying drawings, Figure 1 is a view partly in elevation and partly in section of our improvement applied to a suction sweeper, and Figs. 2 and 3 are views in section of modified forms of deflectors.
1n the drawings, we have shown the dust collector' carried by and forming a part of the sweeper, but it is clearly evident that it may be either a iixedor portable structure connected to the sweeper or suction device by a flexible hose, hence we would have it understood that our invention comprehends both types of apparatus.
- Thesweeper or suction part 5 of the apparatus may be of any approved form, preferably having a suction fan operated by a motor, but the suction means may be actuated by suitable gearing connected with the wheels 6 on which the apparatus is mounted .to travel.
The washer in which the dust is saturated with water is provided with a duct 7, connected as shown, or by a liexible hose as ex-J plained, with the suction device on sweeper into which the dirt and dust laden air are forced by the suction fan or other device. 'this duct is preferably enlarged at its inlet Specification of Letters Patent.
1920. Serial N0. 372,761.
end and passes into the washer 8 and is curved so as to avoid all angles which would retard or deflect the air current passing through the same. Itis curved upwardly at about the center of the washer 8 and carries the pipe A9 which forms a continuation of the duet and which passes upwardly through the sediment chamber 10 of the washer, and terminates near .the top thereof, its upper end being open for the free escape of the dustand dirt laden air. The washer 8 is partly filled with waterthe normal level of which is below the perforated bottom 11 of the sediment chamber 10. This sediment chamber is shaped to conform to and fit within the washer 8, and preferably extends above the plane of the top of pipe 9, which latter passes through the perforated bottom 11 of chamber 10 so that all the dirt laden air will be discharged in Vthe sediment chamber. This chamber 10 is seated on the lugs 12 and also on' the duct 7 with its perforated bottom preferably in a plane above the normal water level in the washer 8, and it and "the washer are closed by the cover 13 provided on its. underside with an inverted conical deliector 14 which may be plain as shown in Fig. 1, serrated as in Fig. 3, or its 'lower edge may be extended and curved inwardly so as to deflect the water and dust towardthe center and away from the sides and thus prevent upward splash as in Fig. 2.` Any upward splash that might carry the water through the screened openings 15 in the cover 13 may also be prevented by the defleetors 16 formed integral with the inner faceof the flange 17 of the cover 13. This fiangeits snugly within the upper open end of the washer and rests on the upper edge of the sediment chamber 10 and forms in effect an extension of the latter.
Secured to the bottom of the water chamber 8 and passing through the curved duct 7 is the pump body 18. This pump body passes upwardly through pipe 9 approximately in the center of the latter and terminates in a 'plane under the apex of the inverted cone and preferably above the upper end of pipe 9 and is provided 4at its upper end with a series of small openings through which the water is ejected in the form of a fine spray so as to saturate all the dust and dirt drawn up by the air blast through pipe 9. Located in the lower end of the' pump body 18 is thepump 20 which is preferably of the screw type as shown.
This screw is provided within the hollow bottom 21 of the/ sweeper with a pulley 21a around which the belt 22 passes, the said belt being driven by the main suction motor.
This pulley is seated on the bottom plate of the sweeper and makes a close fit with the bottom of the washer and it and the plain lower end of the screw, which ts snugly within the pump body,prevent any leakage of water down into the hollow bottom 21. The portion of the pump body within the water chamber of the washer is provided with an opening 24 for entrance of water to the pump body and as the screw is Irotated the water is forced up the pump body andl out through the perforations at the top of the latter where it intercepts the dust laden air and thoroughly saturates the dust and dirt drawn up by the air. The perforations in the top of the pump body are so proportioned to the lifting capacity o f the pump,
' that the water will be'forced out under presfao sure suficient to produce a fine spray, so" that all the dust and dirt drawn in with the air will be enveloped by the spray and saturated and settle down in the sediment chamber 10, while the air freed of its dirt and dust will pass out 4ci? the screened openings 15.
In the operation of the sweeper the dust and dirt drawn into the sweeper by .the yfan or blower is directedvinto the duct 7' and up through pipe 8 and is discharged from the latter into the sediment chamber 10. As the pump is driven by the suction motor, it will be seen that as suction is started, the water in washer 8 will be forced upwardly through pump body 18 byf the pump 20, andissuing at the top of pipe `4 9 in the form of a spray will envelopl and saturate the dust and dirt drawn up with the air, which striking the deiiector 14 spreadslaterally. and is-then defiected downwardly Iinto the sediment chamber. The air discharged into the sediment chamber is washed by its contact with the water and 'passes' out through the screened openings 15 which are sufficiently large to slow down the air, and the water carrying the dirt and dust Jfalls into the sediment chamber and filters through the solids and drains back into the washer 8.
The liquid is then returned to be used 'over again and as the solids are retained in the chamber 10 they form a filter bed through which the liquid is cleansed in its passage .Y
back to the washer. The chamber 10 is of a size suiiic'ient to hold all the dust collected in several weeks of` ordinary sweeping and the amount collected can be readily ascertained at any time by simply 'lifting the? cover 13, the washer can be refilled with water at any time, and as the chamber 10 is removable it can be removed and cleaned as often as ma be necessary.
It is evi ent that many slight. changes,
might be resorted to in the relative arrangement of parts shown and described without departing from'the spirit and scope of our invention. Hence we would have it understood that we do not wish to confine ourselves to the eXact construction and arrangements of parts shown and described, but
Having fully described our invention what we claim as new and desire to secure by Letters-Patent,` is

2. Thecombination of a suction device, a water chamber, a sediment chamber above the water chamber so that the water carried up by the air blast and deposited in the sediment chamber may drain back into the water chamber, a duct leading from the suction device and discharging 1n the sediment chamber and a pump for pumping water from the water chamberand discharging it into the dust laden air as the latter leaves the duct.
