DUST-SEPARATOIR. FOR STREET-SWEEPING MACHINES;
Specification of Letters Patent.
Patented May 15, 1917.
Application filed September 12, 1916. Serial No. 119,649.
T aZZ whomit may concern.-
Be it known that I, JOHN R. PoL-Locx, a citizen of the United States, residing at the county of Los Angeles and State of California, have in vented new and useful Improvements in Dust-Separators for Street-Sweeping Machines, of which the following is a specifi cation.
My present invention is an improvement on that certain street sweeping machine for which Letters Patent were issued to me September 29th, 1915, No. 1,155,272. In the practical use of that machine I found that when a heavy fan pressure was used a considerable quantity of water inthe form of spray was forced through the air delivery pipes which was objectionable. It is the object of my present improvement to overcome this objectionable discharge of spray. To that end my improvement consists in the omission of certain parts, change of the form of other parts and in changing the location of certain of the ports and passageways of the machine.
In the drawings forming a. part of this application Figure l is a side elevation, partly broken away, of so much of the machine as illustrates my invention.
Fig. 2 is a section on the line 22 of Fig. 1.
Fig. Fig. 2.
3 is a section on the line 3-3 of 4 is a top plan of the parts shown in partly in section and partly in elevation, the section being on the line 44L of Fig. 1.
In my improved machine the suction head and pipe connecting it to the dirt chamber and the exhaust fan and its connections are of the same construction and relative location as in said patent.
Referring to the drawings is the dirt chamber. Pipe 11 connects this chamber to the suction head (not shown). This pipe by means of an extension 12 opens into chamber 10 near the middle at the top and on one side thereof. The side walls 13 of the dirt chamber are parallel to and spaced from the outer walls 14 of the body of the machine to form vertical air expansion.
7 Above this partition is an opening 17 in the top wall18 of the body which extends nearly the width of the dirt chamber for the escape of the air from the expansion chambers. The bottom wall 19 of the dirt chamber is parallel to the top wall of the body and said wall 19 is extended to the outer walls of the body and forms the bottom walls of chambers 15. At the front ends of the expansion chambers and in the bottom walls thereof are ports 20 which connect the chambers with the water a chamber 21. Projecting downwardly from is desired to supply the water chamber with water door 27 would be closed and door 26 opened. An operator with a hose connected to a water supply can lead a suitable supply of water into the water chamber through port 20. Pipe 28 connects the dirt chamber with the fan.
In the operation of my machine fan is operated by any suitable power and as the machine is propelled over the street draws the dirt into the dirt chamber through pipe 11 and extension 12. The incoming dirt laden air strikes the sloping top wall 16 which causes the heavier particles of dirt to fall upon the bottom of the dirt chamber. The dust laden air then passes through the fan and into the water chamber between partitions 22 and 23 and is then forced under these partitions through the water to the outer sides of these partitions and through ports 20 into expansion chambers 15. these ports are at the front ends of the chambers and the outlet from the chambers is through opening 17 which is of much greater capacity than the combined area of In a separator for street sweeping machines, means to purify the air of dirt and dust comprising a body having an opening in the top Wall at the rear end; a dirt chamber Whose top Wall except at the rear poi tion is formed by the top Wall of the body, and the rear portion of said top Wall sloping downwardly and rearwardly; expansion chambers at the sides of said dirt chamber the bottom Wall of which chambers have ports therein at the front end and the top of said chambers connecting With the opening in the top Wall; a Water chamber below said Copies of this patent may be obtained for dirt and expansion chambers; longitudinal deflectorsdepending from the top Wall of said Water chamber and projecting into the Water When the machine is ready for use; in combination With means to cause the air to pass through the dirt and Water chambers and out of the expansion chambers.
In Witness that I claim the foregoing I have hereunto subscribed my name this 1st day of September, 1916.
JOHN R. POLLOCK.
