WILLIAM v. can, or CLEVELAND, omo. sucTIoN CLEANER.

` Application led January 30, 1192i Serial No. 532,828.

To all whom t may concer/n.'

Be lit known that I, WILLIAM V. ORE, a citizen of the `United States, residing Cleveland, in the county of Cuyahoga and State of hio, have invented a certain new and useful Improvement in Suction Cleaners, of which the following is a full, clear, and exact description, reference bemg had to the accompanying drawings. Y

is invention relates to suction cleaners has for its objectsthe provision of a desmallest possible height, the greatest stability, the minimum number of parts, the maximum of simplicity of construction and the minimum of machine work; the provision of a new and improved arrangement of parts of a suction cleaner; while further objects and advantages of the invention will become apparent as the description proceeds.

.In-the drawings accompanying and forming a part of this applleation Fig. 1 represents a sideelevation and Fig.. 2 a'front elevation of my improved cleaner; Fig. 3 is a cleaner; Fig. l is a top p 5 is a bottom pla-n view ofthe cleaner; Fig. 6 is a sectional view corresponding to the line 6 6 of Fig. 3; and Fig. Z illustrates a slightly modied form of cleaner.

Describing the parts by Areference cl'iaracn ters, 1 represents the fan chamber, which is of substantially cylindrical lar inlet opening 3, and its forward or lower wall lbeing formed with a circular opening 5 for the reception of the supporting plate 6 to which is attached the motor 7. Communicating with the inlet opening are a pair of spaced passageways 8-8 which exatend past the fan casing and thence tor- Wardly tothe eXtreme end of the cleaner casing, said passagewa s growing wider toward their forward en s until they meet and merge at the inlet defined between a forward lip 10, and a rearward lipI l1, and is overhang by the roof 12, yth

these pint" together with the conduits deonstitutincf te nozzle, said fan chamber an outlet neck at the side opposite said noz'le adapted for the attachment of a dust bag. The motor is sealed bj a may be either integral or independent, extending point near the periphview lon tudinally of thev l lgan view and Fig.

ery of the fan chamber. In this way the entire casing may be made of a single casting as shown in Fig. 3, the passageways 88 besuitable screws 17 at the bottom, and other screws 1 8`18 at the top, the latter being inserted radially through the casing into engagement with a member 19 prepared therefor.

At the rear the casing is form'ed with a horizontal bracket 20 to which is pivotally attached a caster wheel 21, and I have shown e carrying wheels be1ng secured to this shaft so that the lheight of the nozzle relatively Yto the door can be adjusted. In case the top of the nozshaft 22 is best mounted beneath the nozzle, but in case this member be made removable as shown at l5a in Fig. 7, this shaft can project between the air passage and the top plate as shown at 22a.

e air passages may either take a substantially horizontal course until the fan chamber is passed and then rise abruptly to the inlet opening 3, as shown in Figs. l to 6 inclusive or may follow a more uniform slope as shown at Stl in Fig. 7. One side of. the fan chamber is formed with an outlet neck curved rearwardly and upwardly for the attachment of the dust bag outer end is secured in the usual manner to a handle 32 pivoted by forks 33 to suitable gudgeons 34 carried by the casing. In case the top plate 15 is integral these gudgeons can be cast directly thereon, but if it be separated, the handle is ivoted to the brackets 8 as shown in Fig. hese gudgeons are located in front of the fan chamber so that e casing may hang pro erly when it is lifted by the handle, and the, forks are bent sharply down toenable the handle to be lown ered parallel to the door without bringing these forks into engagement with the casing.

The inlet opening 3 is normally covered by 31, whose,

a su1table adjusting device such as a lever v -the two passageways.

spiral in shape is located just above one of the passageways and maximum dimension at the top, between he motor, which is the heaviest part of the machine', is located midway between the three carrying wheels and at the lowest possible point and the other members rise to a low point above it. The litter is moved horizontally at first and is lifted only after it has acquired a high velocity, thus producing a high degree of cleaning' power.

While I have described this embodiment in detail I do not restrict myself to suchdetails except as specifically recited in my claims.

Having thus described my invention, I claim is:

1. In a suction cleaner, comprising a nozzle, a) motor fan chamber arrangedin the order named from front to rear, the axis of the fan chamber being downwardly and forwardly inclined, the motor and nozzle being located on the same side of the fan chamber and the inlet of the fan chamber being on the what a rigid structure frame, .an a

opposite side from the nozzle, said fan chamber having an outlet neck at the side opposite said nozzle adapted for the attachthe floor, there being an ment of a dust bag.

2. vIn a suction cleaner, a nozzle having a narrow elongated inlet mouth and two spaced air passageways leading therefrom, a fan casing embraced between said passageways, a motor secured to the side of said fan casing which is nearestv said inlet mouth and ,depending between said passageways upon an 1inclined axissoas to depend near inlet opening in said fan casing on the side opposite said inlet mouth with which opening said passageways communicate, an a dust bag connected to the fan chamber outlet.

3. In a suction cleaner, a casing having a -narrow elongated inlet mouth, a fann With its outlet its v -inlet mouth whose chamber, and two spaced conduits connecting said inlet mouth and fan chamber and communicating with an inlet opening on the side of said fan chamber which is opposite said inlet mouth, said fan chamber being tipped toward said inlet mouth an located between said two cond a fan in said fan chamber, a driving device therefor located between said conduits, and a cover for said driving device extending from one conduit to the other.

4. In a suction cleaner, a having a fan chamber and a nozzle, said fan chamber having its lower wall inclined relatively to the horizontal plane of the mouth of the nozzle with the rear portion of lower wall adjacent to said plane and its forward portion spaced therefrom, said nozzle being located beneath and forward of said, fan chamber, the upper wall of said vfan chamber being formed with an inlet aperture and the sides of said casing being formed with air passages which lea from said nozzle to said inlet opening.

5. In a suction cleaner, a casing having a fan chamber with an intake opening in the rear wall thereof, ioor engaging carrying devicesA with said wall inclined so as to cause said opening to face upwardly and rearwardly, a collecting nozzle located upon the opposite side of said fan chamber from said intake opening a'nd having a downwardly opening horizontal plane substantially touches the lowermost portion of said fan chamber, and a driving device for the fan located between said fan chamber being air passageways connecting said inlet mouth and intake opening and passing on opposite sides of the fan chamber.

In testimony whereof, lI hereunto affix my signature.
