It is obvious that passage of air through the lining IE will carry a slight portion of the Valuable dust through the lining, so it is important that the unnecessary air be by-passed by the valve 24. By-passing the air also gives the air less flow resistance, and the electric motor uses less power.

Description
Aug. 6, 1940.
E. E. THWAITES COLLECTOR Filed March 7, 1938 Patented Ayg. 6, 1940 v v UNITED smms PTENTOFFICE the housing 6 outside of the compartment I1, the foul air passing through the sack 22 and escaping but being deodorized and purified by the contents of said sack.
The valve 24 is also opened when teeth are being cleaned, or grinding is done on base metals, porcelain, or similar materials. The lining I6 therefore remains free of worthless dust. It is obvious that passage of air through the lining IE will carry a slight portion of the Valuable dust through the lining, so it is important that the unnecessary air be by-passed by the valve 24. By-passing the air also gives the air less flow resistance, and the electric motor uses less power.
When it is desired to remove the hood containing the particles of material to be recovered, the front screws 9 may be removed and the nozzle 1 detached. The rear screws 9 may be then removed and the fan assembly including the motor and the hood then withdrawn and the clamp 9 taken off thus permitting the removal of the hood for the recovery of the contents thereof and thereupon the removed parts may be replaced in an obvious manner.
The drawing and description disclose what is now considered to be a preferred form of the invention by way of illustration only while the broad principle of the invention will be defined by the appended claim.
'What I claim is:
In a collector; an inlet air conduit, a nest of filtering chambers formed consecutively one within the other, one of said chambers having a deodorizing agent on the walls thereof, means between the chambers and the conduit whereby air may be conducted from the conduit to one or both of the filtering chambers.
EARL E. TI-IWAITES.
