VACUUM CLEANER Filed Aug. 4, 192" 2 Sheets-Sheet 2 jwwmtoz Frank @5012 Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE FRANK TYSON, F CANTON, OHIO, AS SIGNOR OF ONE-HALF TO LAWRENCE Gr. IPBITZ, OF
CANTON, OHIO vAcuUM CLEANER Application filed August 4, 1927. Serial No. 210,563.
The invention relates to suction cleaners and more particularly to a cleaner having 4 ing at different points means for vibrating the carpet being cleaned by alternating air currents passing through the nozzle of the cleaner.
The object of the improvement is to provide a vacuum cleaner having means for alternately creating air currents through different portions of the nozzle, whereby the carpet, over which the cleaner is operating, is alternately raised and subjected to vacuum cleanwithin the mouth of the nozzle, the carpet being thus rapidly undulated in much the same manner as would result from shaking the carpet by hand.
The above and other objects may be attained by providing a rotary vibrator within the nozzle of the cleaner; said vibrator being open transversely through its center, whereby the induced air current in the nozzle is caused to pass alternately through the open center of the vibrator and around the periphery thereof.
An'embodiment of the invention is illustrated in the accompanying drawings, in
which Figure 1 is a bottom plan view of the 1mproved cleaner, showing the rotary vibrator mounted within the nozzle;
Fig. 2, a detached perspective view of the rotary vibrator Fig. 3, a transverse sectional view through the nozzle, showing the rotary vibrator in position to cause the induced air current to pass entirely through the open center of the vibrator, and I Fig. 4, a similar View showing the rotary vibrator in ,position to cause the induced air current to pass around the periphery of the vibrator as elljflS through the open center thereof.
Similar numerals refer to similar parts throughout the drawings.
The improved vacuum cleaner may include the motor ,1, for rotating the usual fan 2, with in the fan chamber 3, in order to create an induced current of air through the nozzle 4. The mouth 5. of the nozzle. is arranged to have sliding contact with the surface of the its center,
through the central opening carpet, over which the cleaner is operated, indicated at 6.
For the purpose of the invention, theshafiv 7, of the fan, may zle and provided with a pulley 8.
The rotary vibrator may comprise the shaft 9, journaled in anti-friction bearings 10, located in opposite end portions of the nozzle.
A pulley 11 may be provided at the central portion of the shaft 9, and operatively connected to the pulley 8, upon the fan shaft, as by the quarter turned belt 12, whereby the shaft 9 will be continuously rotated during the operation of the fan.
The shaft 9 is open transversely through as shown at 13, and at each side of the center opening, and parallel thereto, is attached a flexible vane 14, of leather or the like, as by the screws 15.
These vanes are of such width that they will contact with opposite sides of the nozzle, when the rotary vibrator is in the position shown in Fig. 3, and the shaft 9 is so located within the nozzle that one vane will engage the surface of the carpet when the vibrator is turned to the position shown in Fig. 4c.
In the position shown in Fig. 3, the induced air current will pass up from the mouth of the nozzle, entirely through the central opening 13 of the shaft, pulling the carpet up into the mouth of the nozzle substantially as be extended into .the noz-- air current to pass upward between said vane and the adjacent wall of the nozzle, remainder of the current passes partly of the shaft, and partly upon the other peripheral side thereof.
In this latter position the carpet is held down upon the floor at the point of contact with the vane 14, while it is drawn up into the mouth of the nozzle at each side of said point, as illustrated in Fig. 4.
It will be seen that as the vibrator is rotated, the carpet will be rapidly undulated, alternating between the positions shown in Figs. 3 and 4:, subjecting the carpet to suction while the cleaning as the carpet is raised and the nap opened. Much the same efl'ect is produced as though the carpet were grasped at one edge and vigorously shaken by hand.
I claim: 1. A vacuum cleaner including suction e means, a cleaning nozzle and a rotary vibrator within the nozzle, said vibrator being open 0 transversely through-its center and provided with a pair of oppositely extending, flexible vanes arranged to intermittently and simultaneously contact with'opposite sides of the nozzle, and means for rotating said vibrator for causing the induced air current in the nozzle to alternately pass through the rotary vibrator and through and around the rotary vibrator. v
2. A vacuum cleaner including suction means, a cleaning nozzle and a rotary vibrator within the nozzle, said vibrator com prising a shaft having a transverse opening t'herethrough, a pair of oppositely extending,
- flexible vanes attached to the shaft and arranged to intermittently and simultaneously contact with opposite sides of the nozzle, and. means for rotating the shaft for causing the induced air current in'the nozzle to alter-' nateIy pass through the rotary vibrator, and
through and around the rotary vibrator.
3. A vacuum'cleaner including a suction fan, a cleaning nozzle and a rotary vibrator within the nozzle, said vibrator including a shaft, a pulley intermediate the ends of the shaft, a belt operatively connecting the pulley with the fan, a transverse opening through the shaft'on each side of the pulley,and a pair of oppositely extending, flexible vanes attached to the shaft on each side of the pulley 40 and arranged to intermittently and simultaneously contact with'opposite sides of the nozzle, for causing the induced air current in" the nozzle to alternately pass through the rotary vibrator, and through and around the rotary vibrator.
In testimony that I claim the above, I have hereunto subscribed my name.
FRANK TYSON.
