CDRPORATION F OHIO snc'rron CLEANER Original app1ication led. October 23, 1922, Serial No. 596,185. Divided and. this application filed September 16, 1927. Serial No. 219,859.
The invention relates to means for removing dust and dirt from floor coverings or the like by a rapidly moving current of air acting in combination with an agitator -which agitates and vibrates the floor coverlng to dislodge the dust and idirt embedded in it,
- the air current acting primarily as means to convey away the dirt and dust dislodged, although it would of itself remove the surface dirt or that lying in the pile of the carpet relatively close to the surface.
The invention disclosed in this application is a specific embodiment of the generic invention disclosed in my application Serial Number 596,185, filed Oct. 23, 1922.
An essential object of the invention is the combination of means whereby the object being cleaned is held suspended across lthe cleaner suction' opening by the pressure-'difference existing within and without the nozzle, with an agitator driven at al relatively high rate of speed and provided with elements so mounted and arrangedxas to deliver positive blows to the object being cleaned, in
vorder that such object may be positively agi- Avision of the combination of a suction cleaner having a suction mouth so arranged that the object to be cleaned will be raised and held suspended across the mouth by the suc- A tion, with an agitator comprising a series of agitating members lhaving fixed orbits of travel, which orbits intersect the.,surface assumed by the floor covering unde'r the action of the suction. Due to the inertia of the dirt and dust in the iloorvcovering, such dirt and dust will tend to remain stationary while the v covering is being agitated and thus the dirt,
and dust may be loosened from Vthe ioor covering whereupon the air current flowing through the suction cleaner may readily remove such dirt and -Vdust and convey it away into a suitable collecting receptacle.
A still further object of the invention is to provide a construction in which the surfacecontacting portion of the agitator is so constructed that the wear upon the fioor covering or other object being operated upon is a minimum, and yet one wherein the cleaning effectiveness of the machine will not be sacriiiced in favor of a low wear rate.
The invention is illustrated in the accompanying drawings wherein Fig. 1 is a side elevatioinwith parts broken away showing the essential operating portions, of a-cleaner constructed in accordance with the invention;
Fig. 2 is a longitudinal section on line 2 2 ofl Fig. 1 disclosing the agitator in elevation;
Fig. 3 is a detailed View oi a modified form odthe agitating element shown in Fig. 4; an
Fig. 4 is a detailed tator element per se,
Throughout the specification like reference characters are used to indicate like parts.
I have incorporated my invention in a suction cleaner formed of a casting 10 to which is pivotally secured a' handle 11. In this illustration of the agicasting 10 is formed a fan chamber 12 having an outlet 13 adapted to receive a dust collecting bag (not shown), and an inlet opening 14 which connects with a suction chamber or nozzle 15 extending to the front of the. cast-ing, and which `is formed with a downwardly vided with lips y17, 17.
On the casting 10 is mounted an electric motor 18, the shaft 19 of which carries the fan 20 and the pulley 21", the latter positioned in the rear of the suction chamber. The rear of the casting is supported by means of the vertically adJustable wheel)r 22 and the front by means of rotatably mounted carrier wheels 23 positioned one at each lside of the casting and to the rear of the suction mouth in such a manner as not to prevent theobjectbeing cleaned from being raised freely to thefsuction mouth.
' Directly above the open mouth of the suction chamber adjustable rotor or agitatorV supports 24, 24 are mounted on the end walls 25, 25. These supports in turn carry a shaft facing suction mouth 16 pro- 26, upon which is rotatably mounted the hollow tube 27 forming the body of the rotor or agitator. This rotor body is provided intermediate its ends with a pulley 28 which is connected with pulley 21 on the motor shaft by means of the belt 29, which is given a 90- degree turn. i
In the embodiment of the invention as illustrated in Figs. 1, 2, and 4, the rotor body is shown as provided with a helical row of projecting agitating elements eachl composed of a forked bracket 36 having arms 37-37, between which a surface-contacting roller 38 is rotatably mounted onv a pin 39 seated in the arms 37-37, the bracket 36 being mounted adlially with respect to the axis of the rotor Iiir Fig. 3 there is shown a modi-ied form of agitating element which :functions in the same manner as the agitating roller element 38 shown in Eig; 4, the difference being only in that the surface-contacting element' comprises a ball 45 rotatably mounted in the cupshaped portion 46 of the pin 47. The roller elements composedof a hard, smooth material, which will slide over the common types of floor covering with a minimum 'of friction and which will not rust or corrode or in any manner stain the floor covering acted upon.
The agitating elements or members 38 and 45 have a rolling contact with the floor covering being acted upon instead of a sliding friction such as would be the case were they vnon-rotatably mounted through being formed solid. and integral with their supports. Thus the friction between these elements and the floor covering is a minimum and the wear on the'covering is correspondingly low.
It is to be noted that the nozzle lips 17, 17 are maintained at a substantial distance above the floor covering in order that the floor covering may be raised against the nozzle lips and thus, as it may be termed, cushioned on air in orderthat the ioor covering may be positively agitated or vibrated through the action of the rotating agitating elements aforedescribed.
The agitating elements 38 and 45, being mounted in rigid frames, will consequently have fixed orbits of travel with respect to the axis of the body on which they are mounted and therefore, as the entire agitator includ ing the main body and the agitating elements rotates, the elements will forcibly cont'actthe carpet to positively agitate and vibrate it by driving it in a direction away from its raised position. The carpet will immediately be returned to its original position .through the action of the reduced pressure inthe suction chamber or nozzle, and the dirtand dust embedded in the floor covering which has been dislodged by the elements ewill be carried 0E by the air current fiowing l'into theoleaner nozzle.
