RAY WIBAUG-HMAN, OF LOS ANGELES, CALIFORNIA.
STREET-SWEEPING APPARATUS.
Application ifiled May 31,
To all whom it;.may-c 0ncem:
Be it-k-no'wn that I, :RALY W. BAUGHMA acitizen of the United States, residing at LosAngeles, in the county of Los Atn-geles and State ofCalifornia, have invented a new and useful Improvement in Street-Sweeping Apparatus, ofwhich the-following is a specidischarged.
My invention relates particularly to street sweepers of this type in whichthe final dust "separation is accomplished by blowing the air through Water which catchesand holds the fine particles.
The object of my'invention is to provide a very rperfect separation of dust and air.
Further objects and advantages :will be made evident hereinafter.
Referring to the drawings which are for illustrative purposes only,
i Fig. 1 is a plan view of one embodiment of my invention.
Fig. 2 is a section on a plane "represented by the-line 2-2 of Fig. 1.
Fig. 3 is a section ona by the line 3-3 of Fig. 2.
Fig. 4 is a section on a plane represented by the line 44 of Fig. 3.
Fig. 5 is-an enlarged view of the suspension means.
plane represented In the form of the invention shown, a"
sheet metal body 11 is provided mounted on wheels 12. Carried on the body 11 are two exhaust fans 13 which are driven by an engine 14 through pulleys 15 and 16 and a belt 17 or by any equivalent means. -Air is taken into the exhaust fans 13 through a flexible tube 18 which is connected to the 1921. Seria1'N0-.- 473,718.
The air fiowingthroughthese side channels is delivered. into a large depositing chamber 21 having a sloping bottom 22 on which all of the. larger materialis deposited, .being taken out through a-door 23. The air containing the fine dust passes upwardly through channels 24and into a throat 25 which communicatesthrough a flexible conduit 26 with an inverted-pan 27. This inverted pan has its lower-lips submerged in a body of water 28. The path 27 is provided at-either end with a ball'30-which is engaged by a cup'31 carried on an arm 32 which'is rigidly secured to a shaft 33. Each of the shafts 33 extends through the body and is provided with a -;pendulum' 34 which is rigidly attached to the shaft 33 outside the body. Secured tooneend of the pan 27 is a bracket 40 which is connected through a universaljoint 41 with a shaft 42 which in turn is connected through a universal joint- 43 with a shaft 44 carrying a pendulum 45 which is rigidly attached to the shaft 44.
vThe purpose of the members 30 to 45 is to 'maintain a constant submergence of the lower lip of the pan 27 in the water '28 quite regardless ofthe position of the :body 11 as regards the-horizontal.
It should be understood that in operating a street sweeper, it isnecessary for the body 11 topass over grades whereby it is thrown out of the horizontal in one direction and that'many streets-are crowned so that it is thrown out of the horizontal in the other direction especiallywhen operating along produces a displacement therein ofthe water 28. By the use of the pendulums 34 and 45, the pan 27 is inclined so that it is always parallel with the surface of the water so that a uniform submergence is maintained at alltimes. If, for example referring to Fig. 4, the left hand end of the body is raised and the right hand end is lowered, it is evident that'both ofthe pendulums will turn in a counter clock-wise direction about the shaft 33, the left hand end of the pan 27 beinglowered and the 'righthand end: being raised to compensate for changes in the water level. In the same manner the pendulum' 45 tends to keep all the edges of the pan equally submerged in case the sweeper is inclined about a longitudinal axis. As a result the degree of submergence of the lowered edges of the pan27 are maintained constant.- This is a'great' advantage. as it not only provides a reater efliciency of dust separation, but it also allows the sweeper to be operated with a very small submergence which in turn allows the fans 13 to'operate under a lower pressure and with a much greater capacity. The air delivered through the flexible conduit 26 into the pan 27 passes under an intermediate deflector into a space 51 and from thence under the outer edges of the pan into a space 52; it then passes through openings 53 into longitudinal conduits 54 and upwardly through channels 55 being finally delivered to the outer air through an opening 56.
The water underneath the pan 27 is of course displaced to the level of the lower edge of the pan 27, since the air cannot be driven down through the body of water but must displace the water.
I claim as my invention:
1. In a gas washing device the'combination of a portable body in which liquid may be carried; a pan carried in said body having its lower edges submerged in said liquid; means for forcing the air to be washed into said pan; a universal joint at each end of said pan by which said pan is suspended in said body; means for simultaneously raising one end of said pan, and lowering the other end of said pan with relation to said body to compensate for changes in depth of said liquid in said body due to 1011 gitudinal changes in inclination of said body and means for turning said body about said joints to compensate for changes in depth of said liquid in said body due to transverse changes in inclination of said body.
