To all 'whom it may concern:

Be it known that I, GEORGE CLEMENTS,

of Chicago, in the county of Cook and State I of Illinois, have invented a new and useful Improvement in Vacuum Cleaners, of which the following is a full, clear, and exact descri tion. y invention relates to improvementsm l vacuum cleaners, and has for one of its principal objects to a suction hose irectly with the inlet of the pumping chamber such connection causing the nozzle connection between the normal floor nozzle and the'inlet to the pump chamber'to be'disconnected.

It is illustrated in the accompanying draw-- in? wherein-' igure 1 is a side elevation with-parts :0 shown in section, v a

A is a flat cylindrical casing, the interior 80 of which I call the pumping chamber and in it rotates the fan and pumping deviceA.

the axis of rotation so that the pump casing and itsassociated parts may be tilted forwardly and downwardly but not be per- .mitted to proceed too far in that direction.

The conductors B lead from the motor to the controlling switch B on the handle, from which switch leads the flexible conducting wire B, which is shown in Fig. 1 as wound about the hooks B on the handle B The dust receiving bag C is removably attached to 7 one ,end of the tangential discharge way A and at the other end is close by the spring clip C which is supported b means of the spring C D is a re laceable or removable hose tube provided with a screw-threaded portion D to engage the screw-threaded port A in the an extension D and is received into the ort A, the screwthreaded portions D an A cooperating to retain the extension D in seated relation with port A", and a projecting end on which the hose D is adapted to be attached. When the hose" tube is removed, the cap A is substituted therefor and the hose tube may-be screw-threaded into the outlet so as. to deliver air under presure if desirable.

It will be evident that while I have shown in my drawing an operative device, many changes might be made in size, shape and arrangement of the several parts without departing materially fromthe spirit oi my invention.

The use and operation of the invention are quite obvious.

used for cleaning floorsjri the usual manner, the hosetube is removed and the cap A applied to close the port A.

The wirecable is removed from the hooks I and the proper'connection made, whereupon the motoris set in; operation to drive the fan or' pump and suck the 'dust up through the suction nozzle' discharging into the bag C,

whence the 'air escapes, to be collected behind. 'When "the device is tofbe used for wood or other smooth or When the h [is to housed, the cap A is removed and the hose tube secured inseated d as.

from the handle x leaving the material hard floors, the removable squeegee is attached.

' suction chamber and bottom thereof relation in the inlet of the' pump chamber as indicated in Fig. 2. Any kind of a suction device may be'attached to one end of the hose, the other end being slipped over the tprojecting portion of the hose tube.

I the device is tovbe used for delivering air under pressure, the hose tube is screwthreaded into position in the discharge way as indicated in dotted lines in Fig. 2.

The two arms which project from the handle are adapted to be thrown up in osi tion when desired as shown in Fig. 1' to Form a reel on which the cable can be wound.

The handle is connected a little back ofthe center of gravity of the device so that the latter tends to tilt downwardly and forwardly, but the engagement of the handle by the stop prevents the device tilting too far forwardly.
