Specification of Letters Patent.

Patented Aug. 18, 190s.

Application filed September 30, 1907.` Serial No. 395,196.

To all whom it may concern:

Be it known that I, MILES E. FREEMAN, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented certainl new and useful Improvements in Pneumatic Dust-Removers and I do declare the following .to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. L ,j

My invention relates to pneuniatic carpet cleaning apparatus, and more particularly to dust collecting nozzles adapted to be brought into contact with the object to be cleaned, and its novelty consists in the construction and adaptation of the parts, as will be more fully hereinafter pointed out.

In the accompanying drawings,-Figure 1 is a top plan view of a nozzle embodying this invention; Fig. 2 is a longitudinal section taken on line 2-2 of Fig. 1; Fig. 3 is a cross sectional view taken on line 3 3 of Fig. 2; Fig. 4 is a horizontal section taken on line 4-4 of Fig. 3.

Referring to the drawings, a pipe 10 is adapted to be connected with the nozzle 20 in any suitable manner, and is connected at 4its other end to a suitable hose, (not shown),

which, in turn, leads to a vacuum-producing means, such as a fan or pump, (not shown).

The nozzle 20 comprises a throat 21, constructed of the

side walls

22, 22 and the

end walls

23, 23,'and restricted laterally to form a neck 24, which is threaded at 25to engage with the threaded end of the suction pipe 10. l

The neck 24 is bent at 26 to render the device more convenient for the operator to handle and to move over the carpet or other surface to bel treated.

Transversely arranged between the

walls

22, 22 and 23, 23`is'a diaphragm 30, perforated at 31, 31 to permit of the passage of the air and dust through the same to the throat 21. Beyond this diaphragm is a mouth 40, formed ofthe

jaws

41, 41, and within said mouth is arranged an intermediate tongue 42, which extends from the 'diaphragm 30,

which forms the rear wall of said mouth.

' In the construction shown, the

jaws

41, 41 are made integral with the

side walls

22, 22 and form a portion thereof, and the tongue 42 is made integral with the diaphragm 30,

and is placed substantially at right angles thereto. r

The mouth 40 is divided into two

compartments

43 and 44 by the intermediate tongue 42, and this tongue 42 serves the function of a scraper against the surface of the carpet or other object to be cleaned'.

In the use of this device, the vacuum producing means being in operation, the workman' places the nozzle against the carpet in substantially the manner shown in Figs. 2 and 3, with the tongue 42 and the

jaws

41, 41 resting thereon. The nozzle being then drawn over the carpet 50, the nap is raised and the dust agitated thereby enabling the dust to be rapidly drawn first into the

compartments

43 and 44, and thence through the

apertures

31, 31 into the throat 21,. whence it is drawn into the pipe 10 and from there is conveyed to the lfinal place of deposit.

I claim as my invention A nozzle for a pneumatic carpet cleaner, having parallel walls and an apertured diaphragm within its interior, and provided with a tongue extending parallel with the UESSES.
