CARPET sWEEPE'R AND CLEANER. .I

Cleaners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the Alo accompanying drawing, making a part of this specificatiomand to the numerals of reference marked thereon, in which Figure 1 isa vertical section showing a side elevation of the motor. Fig. 2 is av detached perspective view ofthe flexible brush bar. Fig. 3 is a bottom or underside 4view of the disk showing the position of the intake wire. F ig. 4.- is a view showing a portion of the disk in section and illustrating the outer end of one of the intake-wires. Fi 5 is a .horizontall section on the line 5-5 o Fig. 1.

` The present invention has relation to carpet sweepers and cleaners and it consistsin the novel arrangement hereinafter described and particularly pointed out in theclaims'.

ISimilar numerals of 'reference indicate correspondingrpa-rts in all the figures of the drawing.

In the accompanying drawing, 1 represents the top fofthe fan chamber, to which the fan casingl2`is attached. To the top 1 is attached lthe motor 3 by means of a suitable ring-1 1L orYV its equivalent. The motor' shaft 5 is extended downward and through i the fan chamber proper', towhich shaft is fixedly mountedthe hub' 6 frornwhich hub Y extends the fan-arms 7, which arms are pro-A vided'withth usual fan blades 8. Below the hub 6 and upon the motor shaft 5 is se- 40 ourely attached the elastic brush bar 9 by means ofthe'hub lO'and-the set screw 11 or its equivalent. .The bar 9is formed of flexible material, preferably spring steel and the middle or center portion of said brush bar curved upward as illustrated inv'Figs. 1 and 2. 4To the elastic brush-bar 9 are'attached the brushes 12- and for the purpose of providing means for holdingsaidbrushes, the' i 'brush-'holding' heads 13 are provided, which 5`0brushholding lheads are. attached to .the

Specification of Letters Patent: i Patented. Sept. 28, 1909- hub'17, said disk being securely attached to the spider 16 in vany convenient and well known manner.

The disk l15', is provided with series of apertures' 18, through which apertures the 60 brushes 12 extend as best illustrated in Fig. 1, so that the bottom or sweeping ends of the brushes 12 are brought ntovposition to come within direct contact with the carpet or other surface over and' upon which the 65 sweeper proper is moved. The disk 15 serves the purpose' of preventing-the undue lifting T orupward movement of the carpet or rugs or 4other floor covering and at the same time serves the purpose of holding the ,70 brushesl l2 against undue yielding movement, or in other words by placing the brushes 12 through the apertures 18 they are held at points. below the top or connected 75 It is well understood vthat in the operation of'sweepers of thiskind it is necessary'- to pass the sweeper' over surfaces having dif ferent .horizontal planes, as for instance` passing the sweeper from the surface of a waxed or uncovered floor to and upon the Surface of a rug, the horizontal plane varies,

` but byproviding the elastic brush bar 9, the

outer ends of said bar are free to move up and down, thereby, allowing the brushes 12 85'l to be moved upward, but at the same time maintaining the proper amount of frictional contact or sweeping contact'of the brushes 12, regardless of the changing or varying of the horizontal planes or the surfaces over 90 andupon'which the sweeper is passed. As the fan blades 8 are rotated within their chamber, air is taken .in through the central opening 19' formed in the disk 15 and betweenth'e periphery of saidvdisk and the 95 inner surface .of the casing carrying with it the dust and dirt taken from 'the surface lover and upon which the sweeper is passed.

i'. l will move m the direction of motion, there- I' These wires are so formed'that as ,they ro.

tate they will 'have atendency to move the articles toward the central opening 19 which `central opening is formed in the disk l5.

These wires are connected to the disk 1 5 or .'to the spider 16 as desired. The wires l2l extend'frorn points at or near the opening 19,

outwardly and. upwardly and are curved in suchva directionthat their concaved edges r bymoving any articles that may come in f vContact with said. wires toward the centralvi2() any partof thejcarpetbr rugs their outer opening 19. It will be understood that after '.anyheavy orcoarse articlehas passed under .-the'disk -15 and reached the opening '19,

- For the purpose `of manipulating the sweeper, the'yoke 23 is provided, which is pivotallyattached .innthe usual manner and to which the h`andlef24-is c onnected,in anyconvenient land jwell known manner. The

25 and 26, but .the casters, yoke an'dhandle form no specific part "of the present invention. i.

For the purpose of permitting the elastic bar` 9 to be ,moved vertlcally upon the motorl shaft 5, the hubvIO is so connected to the shaft 5 that it .can be brought toward the hub 17 or toward the hub 6, by which arrangement the brush bar can be moved to or 'from the disk 15, so as 'tol adjust-the brush heads 12 yfrom 'time to time as they becomeA worn from use. Ino'rder to provide fory holding the bar9 v` in proper adjustment the set screw 11 is provided, which set screw is for the purpose of holding the hub 10 and the bar 9 at the desired point ofadjustment.'

It will be understood that in order to bring the disk into proper positionA withreference to the fan casing, said casing'V must be open and the disk located in the opening.-
