Description
Patented Sept. 29, 1931 UNITED STATES PATENT ori-ICE i l:MAXIMILIAN WENSAUER, F ISHEBOYGAN, WISCON'SIN,V ASSIGNOB 0F ON-HALF XBESZENZIA WENSAUER, 0F SHEBOYGAN, WISCONSIN vacuum CLEANER l Application andv February 11s, 192s. `senti No. 341,068.
This invention relates to new and useful improvements in vacuum-cleaners and more particularly'to an improved type of beater.
One of the objects Iof my invention is the provision of an improved type of vacuum cleaner with a beater of novel construction g which will prevent, when bcleaning rugs'and carpets, the suction from drawing the carpet or rug into the mouth, especially when Y cleaning the carpet or rug along the edge or border. i Another object of my invention is the provision of a novel type of beater which is removably attached to the vacuum cleaner and .15 is so constructed as to cover the maximum amount of surface in its operation, andwill permit practically all of the dust and dirt removed through its operation to be drawn upwardly into the cleaner through the suc-` tion at each'stroke of the beater.
' In the majority of the beaters used in vacuum cleaners on the market at the present time, a great portion of the beater is provided with a flat surface which strikes the material being cleaned so that the, dust or dirt beneath this flat surface can not be drawn into the cleaner, but in a great many instances is left on the object after the cleaner has passed thereover. This, however, is eliminated with my improved type of beater as the surface of the beater which strikes the object is reduced to a minimum.
A further object of my invention is the provision of an oscillating beater which can be used as an attachment for various well known makes of vacuum cleaners o'n the'marhet at the present time, or canbe constructed as a permanent part of the cleaner. Y
With the above 'and other objects in view, the invention consists in the novel features of construction, the combination and arrangement Vof parts' hereinafter more I fully set forth, pointed out in the claim and shown in the accompanying drawings wherein:
Figure 1 is a side elevation of a vacuum cleaner with the working parts thereof shown in cross section Figure 2 is a horizontal section on the line 2--2 of Figure 1; v
Figure 3 is a vdetailed plan view, parts of the section illustrating aslightly modified manner in which the beater may be mounted.
In the accompanying drawings, I have illustrated part of a well known make of vacuum cleaner on the market at the present time with my improvement incorporated in the construction. The cleaner includes the usual motor body 1, supported by the wheels 2 and having the power shaft 3 extended outwardly through the fan casing 4. The fan 5 is mounted upon the shaft 3 within thecasing 4 and is provided with the usual conical shaped central part 6.
In the construction of my'improveddev1ce, the shaft 3 is extended into the front housing-7 and has thereon a pulley 8 adapted to be engaged by a belt 9 which passes downwardly over a second pulley 10 on a stub shaft mounted upon the bearing substantially triangular shaped upright supports 11.
The pulley 8, as shown, is in clutch connection with the hub of the fan 5, and a button 9 is in threaded union with the outer end of the shaft 3 for controlling the clutch connection. By this arrangement the clutch will disconnect the pulley, whereby motion of the beater is stopped and the fan will continue its functions.
The beater is supported within a rectangular `frame 12 fitting within the open lower end of the housing?- and secured by means of the screws 13. The beater itself comprises a shaft` 14, the ends of which are mounted in the end portions of the frame 12 'and this shaft is located at one side of the frame as shown in Figure 2 and in close proximity to the side of the frame.`
Extending laterally from the shaft is a crank arm 15 having connected to its outer end a pitman 16 which is eecentrically connected to the pulley 10 as clearly shown in Figure 1. This connection imparts a rocking movement to the shaft 14 when the motor is in operation.
Connected to the shaft 14 at spaced intervals are the U-shaped beating members 17 which extend transversely of the frame 12 with their intermediate portions arranged adjacent the side of the frame opposite the s shaft 14. These U-shaped members are 100 preferably formed of comparatively heavy wire or light metal having some resiliency so that when the intermediate portions 0f the U-shaped members contact with the upper surface of a rug, carpet or the like, it will have a tendency to give.
Any number of these members may be used in connectlon with the shaft 14 and they may be spaced various distances apart, but it will be apparent that when the beaters contact with the rug, carpet or other surfaces, the surface covered will be so small that it will not prevent any of the dust or dirt from the article from being sucked up into the housing 7.
Some of the beaters in vacuum cleaners at the present time have comparatively large striklng surfaces so that when the beater strikes the article being cleaned, it covers considerable surface and the dirt and dust under the surface of the beater cannot be sucked into the housing 7, and therefore, necessitates a greater movement of the cleaner over the surface being cleaned, but with my improved beater, one passage of the cleaner over the surface being cleaned will be sufiicient as there is no uncleaned surface remaining after the cleaner has once passed thereover.
Nearly all of the vacuum cleaners, or a great majority of them are provided with substantially elongated mouth portions such as shown in the accompanying drawings and the frame 12 can be readily positioned within the mouth portion as .shown in Figures 1 and 2, thus, the frame and beater carried thereby can be easily applied to various types of cleaners.
If, however, the beater is to be placed in the machine at the time it is manufactured, the construction illustrated in Figure 3 will prevail, this structure includes a boss 18 formed at each end of the housing 7 at its mouth, each of said bosses having an vinternally screw threaded opening to receive the bearing screw 19. The inner ends of these screws 19 are tapered as at 20 to engage within similar shaped recesses 21 formed in the ends of the shaft 14. The beating member 17 and shaft 14 outside of the ends thereof are ofthe same construction as that previously disclosed. Attached to the housing 7 adjacent the mouth thereof is a shaft 22 having at each end the rollers 23 which is ordinary construction in certain types of vacuum cleaners. These rollers support the lower end of the housing 7 in proper spaced relation with the surface being cleaned.
It will be apparent from the foregoing, that in the operation of my device, movement is imparted to the pulley 8 during the operation of the motor 1 and this movement is imparted to the pulley 10 through the belt 9, pulley` 10 operating pitman 16 which oscillates the shaft 14 and moves the beating mem- U-shaped beating bers 17 into and out of contact with the surface being cleaned at a high rate of speed.
I claim:
In 'a vacuum cleaner having a suction nozzle, a substantially rectangular frame fitted in said nozzle, spaced substantially triangular-shaped upright bearing members carried by said frame, a shaft supported at thepupper ends of said bearing members, a longitudinal shaft carried by the frame at one side thereof, spaced U-shaped beating members having their ends connected with, said shaft and disposed at the inlet end of the nozzle, a crank arm extending laterally from the longitudinal shaft, a pulley carried by the first shaft, a pitman having one end connected to the o uter end of the crank arm and the other end eccentrically connected to the pulley, and means for imparting movement to the first shaft for rotating said pulley and rockin the longitudinal shaft to impart an osciliiiting movement to said U- shaped members.
In testimony that I claim the foregoing I have hereunto set my hand at Sheboygan, in the county of Sheboygan and State of Wisconsin.
