JOHN C. BBEHM, BAYONNE, NEW JERSEY BEATER ATTACHMENT FOB VAQUUM CLEANING HAG HIN ES Application filed latch 98, 1928. Serial No. 864,288.

This invention relates to vacuum cleanin machines and particularly to the provision 0 a beaterattachment for machines of the class specified; and the object of the invention is to provide a beater attachment in the form of a nozzle adapted to be moved over a surface to,

be cleaned,the open end of the nozzle having a beater member arranged therein and ada ted to be actuated inwardly and outwar y with respect to the opening of the nozzle to engage and strike a surface to be cleaned, to raise the dust from such surface to be drawn through the nozzle into the dirt receiving ,receptacle of the cleaner, facilitating the more thorough cleaning of rugs, carpets, cushions and like coverings and facings'; a further obvject of the invention being to provide a nozzle of the class specified which may, by virtue of its constructlon, be universally adapted to many of the standard makes of vacuum cleaning apparatus and including means for placing t e beater element or member in operative connection with a rotatable or other operable member of the vacuum cleaning appa 95 ratus, said beater element being positively,

moved in one direction and tensionall o r ated in the other direction; and wit t ese and other objects in view, the invention consists in a device of the class and for the pur-- pose s ecified, which is sim Is 'in construction, e cient in use, and whic is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following s ecification, of which the accom-.

panying awing forms a part, in which the separate parts 0 my improvement are designated' by suitable reference characters in each of the views, and in which:

Fig. 1 is a side and sectionalview, diagrammatically illustrating a art of a vacuum cleaning apparatus, and s owing one of my improved nozzles mounted in connection therewith.

2 is a section on the line 2--2 of- Fig. 1' an Fig. 3 is a face view of a part of the-apparatus shown in Fig. 1 and with part c the "construction broken away. V

In the drawin I have shownfor the purp pose of illustrating one use of my invention,

a vacuum cleaning apparatus 5 of a conventional type consisting of a fan or suction casing 6 in which a fan 7 is rotatably mounted. The fan is driven by an electric motor contained in the casing portion 8 of the appa- 5n ratus, the casing 6 having a tube 6 leading therefrom'with which the bag or dust receiving receptacle 9 is coupled. The apparatus is mounted on suitable wheels 10 facilitating its free movement over a floor or other surface. so

Inthe construction shown, the usual suction nozzle of the machine has been removed or detached as is customary in many standard types of machines and substituted therefor is my improved beater attachment 11 compris- .66 ing a'casin ,one end 12 of which is tubular in form an flanged as seen at 13 to be mounted and coupled with he casin 6 to bring the tube 12 in alinemen with t e aperture 6" opening outwardly into the fan or suction chamber thereof. The free end of the beater casing 11 flares laterally and downwardly to form a comparatively wide and'elongated nozzle end 14 which is movable over the surface to be cleaned, this 7 open end being directed downwardly in the manner of other nozzles of this type.

-M0unted in suitable bearin 15 and 16 within the u per end portion 0 the casing 11 is a'shaft 1 the outer end of which is provided with a coupling 18 adapted. to enga e the fan 7 or the shaft of said fan whereby t e rotation of 'the'fan will corres ondin 'ly rotate the shaft 17. Secured to t e sha t 17 is a cam wheel 19, the cam surface 19' of which is arranged on one side of the wheel 19 and is adapted to actuate an arm 20 to correspondingly operate a beater element 21.. The upper end of the arm 20 preferably carries an antifrictional bearing member20", which rides over the cam -surface 19", the latter being of such contour as to gradually raise the beater element 21 or draw the same into the neck portion 1a and out of engagement with a surface to be beaten or cleaned and to release the arm suddenly, whereby the spring memher 21 of the beater element which has been laced under tension in the above operation actuates to suddenly move the element 21 into 1.

ough the casing and 70 engagement with the surface to be cleaned as will be apparent. 1

In the construction shown, the beater element 21 is fashioned from wire bent into comparatively wide and flat coil portions 21 which may be described as of sinusoidal or serpentine form which extend substantially through the entire area of the open end of the member 11 or the nozzle 14 thereof, and the Wire from whichthe element 21 is formed is coiled about a rod or shaft 22 as seen at 22 note Fig. 2. In the construction shown, the spring member 21 constitutes an integral part of the wire employed in said coils and engages one wall of the nozzle 14 as clearly seen in Fig. 1 of the drawing. Itwill also be noted that the lower end portion of the arm 20 is yoke-shaped in form, being also constructed of wire, and the ends'of said wire are wound around the rod 22 and have portions 23 engaging parts of the coils 21 to raise the same against the tension of the spring member 21 as above described. The central portion of the arm20 also preferably passes through a yoke-shaped guide and stop member 24, constituting part of the attachment 11.

From the foregoing, it' will be apparent that in the operation of the vacuum cleaning apparatus, with my improved attachment mounted in connection therewith, the rotation of the fan or suction elementof the machine will transmit movement to the beater element 21 through the cam 19 and arm '20 to intermittently and repeatedly raise said element, the beating action to the element being transmitted by the spring member 21 to lightly and yet effectively raise the dust that may be contained in a carpet, rug, pillow, cushion or the like, or upholstery of chairs, vehicles and other apparatus. As the dust is raised from the member being cleaned, it is sucked through the attachment and collected in the receiving receptacle-9.

It will be understood that my invention is not necessarily limited to the specific struc-' ture of beater element herein shown anddescribed, nor to the specific means of actuating a heater element, nor. is my invention necessarily limited to the s cific general contour of the attachment isclosed. Various changes in and modifications of the construction herein set out ma within the scope of the appen ed claims, without departing from the spirit of my invention or sacrificing its advantages.

Havin fully described my invention, what I c aim as new and desire to secure by Letters Patent, is:

1. In a vacuum cleaning apparatus having a suction nozzle in communication with the suction creating means of the apparatus, a beater element arranged at the open end of said nozzle and adapted to oscillate inwardly and outwardly with respect to the 17th day of March, 1928. JOHN C. BREHIJ. v
