I CARPET SWEEPER.
APPLICATION man MAY 6. m4.

r To all whom it concern. 7
j wrnnrma, noses, or-naooxnrnfnnw'ronx we canrnr-swnurnnl Be it known that I, W it AoROAtJH,
a citizen of the United States, residing at Brooklyn, inthe county of Kings, State of New York, have invented certain new and useful Improvements in Carpet-Sweepers;
' andI do hereby declare the .following to be a full, clear, and exact description ofvthe invention, such as will enable others skilled in theart to'which it appertains to make and use the same. 'This'in vention' relates to sweeping devices, particularly to a carpet sweeper adapted for domestic use, and has special reference to thep'rovision of means for the ,removal of lint, threads, and the like from the rotary brush.
important ob ect is the provision of a lint and thread removing comb' detachably 4 and adjustably connected with thefframe' of a' carpet sweeper and havingteeth of novelconstruction; 4
Other objects and advantages, such as simplicity, efiiciencyydurability .in service, and the general improvement of the art, 'willbe brought out in the following description and illustrated in the accompany ing drawings, in whlch, v
- Figure 1 is a top plan view of the sweeper with thetop of the "outer casing removed,
Fig. 2 is across sectional view thereof, Fig. 3 is a detail view of the comb detached,
and, Fig. A is a sectional view through. a]
portion of .the comb, showing the tooth con+ struction. 1
Referringmore particularly to the drawings, the mainframe of the sweeper comprises side and end bars 5-and 6 secured to each other and arranged in a preferably rectangular -form. Longitudi'nally extending bars 7 connect the end bars 6 and are provided upon their ends with spindles or shafts 8, upon which arerevolubly mounted preferably rubber tired wheels 9. The usual to brush 10 formed on the spindle 11 is journaled on the end bars 6, and has provided upon its ends, friction rollers 12 disposed between and engaged by the wheels 9. The frame is inclosed by-a casing 13 suitably seifiO cured upon the'frame and formed of wood or sheet-metal, was-desired. The usual dust pans '14 are disposed withinthe frame and connected-with the end barsfi in any well known or preferred manner.
My device for removing accumulations ofthread, lint, hair, and the like which collect Specification or Letters more Patented n13 20, 191 5. 71 Application new 1914; Serial No. 836,703.
on the brush 10 during its rotatiom is 1 g the .form of a comb, designatedbroadly by the numeral 15. Thecomb 15 is adapted .to be secured upon one of the'bar's-7 and. is .formed .preferablyrfrom a single sheet of metal, preferably steel, and. comprises a main or body portion lfi havingoa plurality of teeth 17 extending, therefromin a position to be engaged bythe bristles of the rotatihg brush 10. In order that the teeth "-17 may exert the proper cutting action upon lint, thread, hair, and thelike carried by the bru sh 10,I'preferably bevel the opposite sides of the teeth, as shown at 18,in order that the extreme upper portions of the teeth may be formed as knife edges 19. The teeth 4 17 are pointed, as shown. By constructing the teeth in this manner, it will be seen. that they constitute in eflect, a plurality of knives which 'will' eflectually remove any matter clinging to the brush.
In order to secure the comb 15 upon the bar ,7, provide U-shapedclips 20 having their arms disposed above the comb '15 and below the bar 7 The upper arms 21 of the clips 5 20 are provided with screw threaded.
apertures for the passage of set screws 22, which extend therethrough and engage the top surface of the body portion 16 of the comb, for clamping it firmly upon the bar 7.
It will be obvious that when the device is moved over acarpet, rug, or the like to be cleaned, the wheels 9 will.rotate, and by. virtue of their engagement with the rollers 12, will also rotate the brush 10, sweeping the dust,'d1 rt, and the like, into the pans 14', as iswell known. As the brush revolves its bristles will pass between and be engaged by the teeth 17 of the comb, which will consequently 'cut and tear ofi stringy material which would otherwise accumulate thereon. If the comb itself should become clogged it may be readily removed and cleaned by releasing the set screws and removing the clips 20. Furthermore, if desired the comb may be readily adjusted either longitudinally of or toward and away from the brush by loosening the screws 22 and moving the comb upon the bar 7, such adjustments being of distinct advantage 7 should the brush become worn through long use or constant contact of the teeth with adjacent points in its circumference;
It will be readily understood that I may make various changes in the form, construction, and arrangement of parts, without de- I claim is,
parting from the spirit of the invention or limiting the scope of the subjoi-ned claim.
Having thus described my invention, What In a carpet sweeper, the combination With a Wheeled frame and a rotary brush, mounted in the frame, of a comb adapted to en'- gage said brush; said comb comprising a body portion having a plurality of spaced 10 teeth formed integrally thereon, and means' detachably and adjustably connectin said comb to the frame whereby the com may be adjusted longitudinally of or toward and away from the brush.
In testimony whereof, I affix my signa- 15 ture, in the presence of two Witnesses.
