SUCTION CLEANER Bernard C. Becker, Canton', Ohio, assigner to The Hoover Company, North Canton, Ohio, a

corporation of vOhio j Continuation of application Serial No. 628,--'813,r August 15, 1932. This application January 29, 1934, Serial No. 768,893

Claims.

The present invention relates-to suction cleaners in general and more particularly to a new and improved suction cleaner embodying means to illuminate the surface covering undergoing 5 cleaning and articles of furniture positioned immediately forward of the cleaner, for the purpose of enabling the operator better to manipulate the machine and to discern foreign material in dark corners etc. which would 'otherwise escape observation. More specifically the present invention comprises the combination of an electric illuminator 4and the motor casing of the cleaner, the parts being so constructed as to direct the rays of an electric light embodied therein forward of the cleaner.

The present application is a continuation of application Serial No. 628,813, filed August 15, i932, now abandoned.

It is an object of the present invention to provide a suction cleaner embodying floor illuminatingl means. It is a further object to provide a suction cleaner in which electric illuminating means are formed upon the motor casing to illu- 'minate the nozzle and the adjacent covering.

These and other more specific objects will appear upon reading the following specification and claims and upon considering invconnection therewith the attached drawing to which they relate.

Referring to the drawing. in which a preferred embodiment ofthe present invention is disclosed:

Figure l is a side view of a suction cleaner with the present invention embodied therein;

Figure2 is a bottom View of the upper remov- 'able portionl ofthe motorl casing with the illuminator embodied therein;

Figure 3 is a cross section through the' construction of Figure 2;

Figure 4 is a partial side View of tie motor casing similarvto Figure l with -the guard-partially broken away.

I n the drawing the .present invention is shown embodied in a modern suction cleaner the body or housing of which comprises a nozzle I, aA fan' chamber 2, and an exhaust outlet' 3. To the latter a dirt receptacle' is removably attached by suitable securing means 5. The upright cylindrical motor-containing casing 6 is carried by the main casing being positioned immediately above the fan chamber and'in the rear of the nozzle I,

a shoulder` being formed at the .bottom of the casing. The cleaner is movably supported upon front wheels 'I and rear wheels 8, one of each being shown, the latter being provided with means. indicated generally by the .reference characier II. by which' they canbe raised and lowered (Cl. 24U-2) to effect the variation in the nozzle hemht above the surface covering undergoing cleaning.

In the suction cleaner constructed in accordance with the present invention the motor casing 6 is formed of a lower section II and an upper section I2. The resulting casing encloses the motor frame I3 which carries the motor brush I4 which is adapted to contact the rotating armature I5 at its commutator. This construction is clearly shown in Figure 1 of the drawing.

Integrally attached to the lower edge of section I2.of motor casing 6 is the floor illuminator guard comprising a hollow body I8 which is formed with an encircling band or collar I8y which Vseats the lower edge of section I2.

The hollow lamp guard body or visor is open at its rear side, as is the section I2 immediately` adjacent thereto. The openings are indicated by the reference character 2land open to the spacel within the guard body *a space within the section I2 the back of which is defined by an imaginary chord extended between thesidesv of the *openings. Within this enlarged space practically all of the illuminating means are positioned. excepting only the continuations of the current conductors hereinafter described The visor and casing section I2 are secured together by rivets I1, Il to form a unitary construction. y

The hollow body portion of the lamp guard-l being adapted to function as a reflector is trough shaped, the interior thereof being preferably whitened or polished forthe purpose of providing better refiecting qualities. Lamp guard I8 is entirely open at its forward side and is so shaped as to direct light beams forwardly and downwardly onto and in fr ont of nozzle I conning substantially all light rays to an angle below the horizontal. On one sidejwall of guard Il is mounted a cylindrical lampbase receptacle I9 which is shown attached to' guard Il though it may well be formed integrally. Y is secured in place through being provided with al threaded. bolt portion: through the guard wall and seats a nut Ib. A' light 20 is ,removably mounted in receptacle I9.' the two parts being removably heid together by a bayonet-socket relationship vindicated at 2I. Closely adjacent socket I9 is mounted a switch 22 through which passes Aone of the currentcarrying leads 23, 23 to enable the operator to turn the light 2l on or off. The leads 2l, 23 pass from the reflector Il through the opening 2l and are attached' to the motor being provided with suitable screw caps 25. 25 at their inner Socket` I9 I9a which extends ends whichA are adapted toiorm n lpart-ofthe u height thereof.

brush mounting i4 and to conduct electric current from that brush to the light.

To protect both the Illuminator and articles of furniture with which it may possiblycome into contact in the operation of the cleaner a furniture guard of resilient material is provided which encloses the edge of the visor I8, being indicated by thereference character 26.

The illuminator is so formed that it can be attached to a standard motor casing, it being necessary only to remove the casing section I2 from the casing section Il, to provide the opening 24 in its side and then to attach it to theband I6 of the illuminator body. When so attached the guard and lamp are disposed within the limits of the cleaner and do not increase the overall The light is protected by the cleaner nozzle from collision with vertical objects, such as table and chair legs and the substantial construction of the guard protects the lamp propel.

I claim:
