Application led May 4, 1907. Serial N0.371,904.

Beit known vthat I, DAVID C. WaL'rnn, a citizen of the United States, residing at Toledo, in the county ofLucas and State' of Ohio, have invented certain new and usel ful Improvements in Pneumaticv Carpet- A to be a full, clear,

such as will enable othersV 10 Sweepers; and I do declare the following and exact description of the invention, skilled in the art to which itappertainsto make and use the same, reference being had to the accompanying'drawings, and to the letters and figures of reference marked giereon, which form a part of this specifica- My invention relates to a pneumatic carpet-sweeper designed in such manner that the entire apparatus shall be so light and lsnnple that 1t may be tra orted and hanmanually and carrie from room to room and placed close to the work to be performed, and which shall be so inexpensive that it may be owned and used by .any person having in his house the ordinary incandescent electric lights.

My invention is further designed to furnish an electric fan and a dust-collector made in two separable partsv which, when separated, may be carried in the two hands of the operator to any part of the house 'where the sweeping or cleaning is to be performed. y

My invention is also designed to furnish a a construction which will permit the fan of my device and its driving motor to be employed separately as a cooling or ventilatlng fan or, conversely, which will permit the ordinary house-tanto be utilized as a pneu- Vmatic sweeper.

My invention relates also to certain de tailsof constructionhereinater described andpointed out in the claims. I attain these objects by means of the d vices and arrangement o paris' hereinafter described and shown, and lllustrated in the accompanying dra in which,-

Figure 1 is a side e evation of my pneumatic sweeper, with a portion of the fancasing broken away and showing in connection therewith one form of dust-collector` which may be used therewith in longitudinal section; Fig. 2 is a top-plan view of the sweeper; Fig. 3 is a side elevation .of

-a .pneumatic broom and connecting hose that may be employed in connection with my sweeper; and Fig. 4 is a front elevation of a separate motor-stand. Y

I employ an electric motor 1o f the usual or any preferred type, having inleading` and outleading conductors 2, these being adapted at one end, as at 2a, for connection wlth' an ordinary electric lamp-socket. The

-shaft 3 of the'motor carries at its outer .ex-

cured in osition by means of bolts' 7. The

bottom vo the casing is entirely Vopen and is carried in close proximity-to or 1n con tact with the carpet over which itis adapted to travel by means of rollers or casters 9, mounted in brackets 10, which are vertically adjustable by means of slots 11 and nuts 12. A handle 15, is connected to the sweeper by means of a bail 16, pivotally sep cured upon either'side of the casin to lugs 17. The top of the casing is provided with a funnel-shaped extension 18, at the rear, which terminates in a tubular connection 20, to which the connection with the dust-receptacle or the pneumatic broom may`be secured with a clamp 21.

Any suitable dust-receptacle maybe em- 'ployed and may be connected with the tubular extension 20 by means of a flexible hose 21a of suilicient length to permit of the movement of the sweeper over the carpet o1' floor through a convenient radius. I have illustrated one form of dust receptacle which may be used consisting of a rectangular `vessel 24 having transverse vertical partitions 25 which do not reach to the bottom or to the top of the vessel. A coi/er 27 having downwardly turned marginal flanges is adapted to lit-closely over the 4upper edge of the vessel, the cover being securely locked by means of hooks 28 upon either side, and having'a handle 29 by means of which the receptacle may be carried. Secured to and depending from the cover are sheet-metal' bathe-plates or deflectors 30, which, when l the cover is in place, project downwardly at equidistant intervals between and in alternation with the partitions 25, and extend entirely across theinterior of the vessel. One end of the vessel is provided with a tubular opening 32, to which the hose connecting with the sweeper may be attached, and at the other end a tubular opening 33 1s adapt- ,ed to receive a hose 35, when'the pneumatic broom or nozzle 36 is to beused. Into the bottom of the vessel 24 is poured water to .such depth that a slight space is-left between the lower margins of the deilectors 30 and the surface of the water, the lower margins of thelates 25 being submerged. The water may e emptied from the vessel by removing the plug from the hole 38 near the bottom. p A

The operation of my device as thus far explained is as follows :--The motor is set in operation by connecting the` plug 2* to one of the electric light sockets, revolving the fan blades rapidly and in a direction to cause a suction upwardly from the carpet,

and exhausting through the hose connection into the dust-receptacle 24. vThe rapidly ref volving blades Ain very close proximity to the carpet.l will cause a thorough cleansing action thereof and will Withdraw the dust and dirt, which will be carried bythe exparatus resides in the combined use of ,resting the sockets 41 of the motor shell upon the set-screws 42 of the stand, and the motor is o erated in a direction to cause 'an exhaust t ough the dust-receptacle and tube 35, and a suction through the broom head 36. y

' It may sometimes be' desirable to use the pneumatic broom as a blower to forcethe dust out of fabrics or outV of crevices, etc., and in thls case the hose 35 may be connected directly to the tubular extension 20 of thev sweeper which is operated in the upturned positlon as before, the motor being caused to revolve in the direction to force the air outwardly through the tube and broom. Another important advantage of my atpsweeper and broom, when itis desired to 'take up dust and dirt from corners of a room and to operate close to the baseboards- In such cases thebroom blows the dirt from the crevices into the path of the sweeper which immediately collects it.

.Insteadof driving the motor in one direction or the other according to whether the fan is actingas an exhaust or as a blower, it is obvious that different fans may be employed having their blades reversely 1ncline be used asan ordinary house-fan by removing the casing 5 and mounting the motor in the stand 40. f

Having described my invention, what I claim anddesire to secure by Letters Patent is,- t

1. A pneumatic carpet cleaning apparatus comprising amotor driven fan mounted upon a vertical shaft, a removable hood inclosing said fan and having an o en bottom, means for movably supportlng said hood. and said fan in close proximity to the carpet, and receiving means for the connected to the hood.

2. A pneumatic carpetlcleaning apparatus comprising a traveling hood having an open bottom, a motor driven fanmounted upon a vertical shaft in said hood in proximity to the open bottom thereof, and dust collecting means connected to said hood.

3. A pneumatic carpet-sweeper, com rising a rotary fan mounted upon a ver 'cal shaft, an electric motor operatively con- It be evident that the blower may nected thereto, a hood inclosing. sald fan having an open bottom detachably secured,

to said motor and. constituting a'suction chamber, means whereby said hood may be m'ved over the carpet with its mouth in' close proximity thereto, and means connected with the hood for collecting the dust.

In testimony whereof I-aix my signature in presence of two witnesses.. e
