To all whom 'it may concern:

Be it known that we, JOHN H. RUSSELL and ALBERT A. CARSON, citizens of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Vacuum-Cleaners for Carpets and the Like, of which the following is a specifcation.

Our invention relates to vacuum cleaners for carpets and the like, and the mventlon consists 1n a hand power clcanerconstructed and adaptedI to operate substantially as shown and descr1bed and particularly 'pointed out in the claims.

In the accompanymg drawmgs, Flgure 1 1s a sectlonal side elevation of the machine with one of several different forms of sucand Fig. 4 is a plan view on line -fv,

the device, showing agravity hood or skirtingat the front of the suction head adapted to close the same upon the floor 'as hereinafter fully described. Fig. 9 is a reduced view of the machine pivotally mounted upon a vertically adjustable standard.

The object and eneral character of the invention are clear y disclosed in the foregoing views, and contemplate a vacuum ma chine adapted to serve the various purposes of such machines forfloor and other work as is now w'ell known, and the machine is projected upon the line of simplicity, lightness and convenience of operation, so that a woman can conveniently handle and operate the same for ordinary housework.

To these ends thcmachine is built with a handle- H adapted to be gripped by one hand and a crank C to be grasped by the other hand, and serving to both handle and guide the machine. The said handle part .I-I is shown as provided with two stems or zlegs'Q of sufficient' length to make the re- -quired connection with casing G of the suction fan F, and the header mouth piece or part indicated by D is removably engaged on the tube or pipe E which permanently connects with the fan casing at its upper end, andthus a rigid structure or frame work is made comprising the parts E, G and I-I and the casing J as we shall presently see. 'lhe said suction head D is provided with a neck or extension 5 sleeved upon the lower end of tubeE and removably engaged thereon, so that it can be taken off and replaced at will, but said tube and casing G are rigidly connected, and a dust receptacle or bag B is hungl upon a hook 6 or the like at one end u on the tube E and engaged at its upper en over the mouth of the ydischarge neck 7 of casing G which opens to the interior of the said casing and provides an outlet through which the casing discharges under the operation ofthe fan.

Mechanism for operating the fan is interposed between the hand crank C and the fan, and the said mechanism is constructed 'to give the maximum of speed to the fan with the minimum of power required in crank C to drive the fan. That is, we have planned ,to obtain the greatest possible volume of suction practicable in a device of thls kind with the least exertion or power to efect such result, and hi h speed as well as ease of rotation of the an are among the things necessary to accomplish this end. Therefore, we have adopted a system of gears mountedin a casing J which is located over or upon the fan casing G and carries the crank shaft 8 and the said gears and pinions4 for driving the fan. These comprise a relatively large bevel gear 9 fixed on shaft 8 meshing with a pinion 10 fixed von a sleeve 11 mounted upon shaft 12 vwhich extends down into casing G and carries the fan. The sleeve 11 is provided with a pinion 13 upon its upper end and said sleeve with its pinions is free to rotate upon shaft 12. Pinlon 13 engages aarelatively small gear 14 about the axis of the large gear 15 which is loosely mounted upon .crank shaft 8 and meshes with a bevel pinion 16 fixed upon shaft 12, so that as the crank C is rotated power is communicated to the fan through the foregoing series of gears, pinions and shafts, and gear 14 is unitary `with gear 15. Now, rctracing the operating connections just described, it is seen that gear wheel 9 meshes pinion 10 110 Which-.drives pinion 13 through sleeve 11, and this pinion meshes with the small gear 14 on larger gear 15 and which in turn4 meshes with the fan driving pinion 1G.

locked on the shaft 12. The fan is driven by this mechanism with comparative case at a high rate of speed and the desired vacuum results in the suction head D. The said suction head comprises the casing or housfv ing D-as a whole which hasa tubular neck 5 sleeved over the extremity of tube E and is supplemented on the inside by two wings or guards 18 which have rigqht angled end port-ions pivoted upon a shaft 20 and constructed to ride or slide .by gravity upon the floor or carpet or other surface over which the tool is being worked, and effeet closure to the outside air. Both Wings or guards accommodate themselves to any inequalities inthe surface and to the angle at which the tool `or head may be held. A screw in each end of the shaft 20 through the wall of head D serves as a trunnion therefor and as a bearing. or support for the wheel or roller 4 outside. No special value is attached 'to this arrangement as it can be readily changed to an equivalent construction for the same purpose. In Fig. l-we show a stationary brush 22 therein, and in Fig. 5 a revolving brush 23. Either may be rused at pleasure and the 'shaft 20 is shown as engaged in the casing D at its ends and equipped with rollers 4 atits extremities outside said." shell or casing and carrying thesame upon the floor -to lighten the work. l 4,

Figs. 6, 7 and 8 show a modification of the suction .head D'and lwhich we jdeem the preferable form. In these views the casing D is provided with a comparatively long tubular neck 24 attached by set screw 25 to the suction tube E and has a revolving brush 26 mounted therein and provided with rollers 27 on the ends of its shaft outside the casing and in friction engagement with rollers 28 which carry the device on the floor and through which and the rollers 27 rotation is imparted to the brush. The said neck 24 is shown as somewhat enlarged at its lower portion o n segmental lines and supplemented by a gravity hood` 30 or guard pivotally` mounted at its rear and base upon the spindle or shaft 34 of wheels 28 and, like guards 18,makes a complete closure around about the bottom of the said head except at the heel orl rear thereof where a rubber or like flexible strip 31 eX- tends lengthwise and is adapted to close off the air from the outside as Well as yield according to the position or angle of the tool to the floor. Thus in this as well as in the other form or forms of the head an effective' skirting of a yieldingl or accommodating nature is interposed about the bottom of the said head or vacuum tool which' accommodates itself to all Working conditions and promotes the efficiency of the suction head as described.

The bag B is of a suitably close Woven duck or drilling which serves to intercept' the dustand yet allows the air to be 'driven through the same, and. is removably supported on the outside of the machine for convenience of cleansing.

What we claim is:

1.*1n vacuum cleaning machines, a suc'- tion head, a shaft lengthwise through said head and a brush mounted thereon, in combinationwith a'gravity dust guard pivotally mountedin respect to said head and adapted to slide over the floor and close the space about the bottom of, said head against suction from the outside.

2. In vacuum cleaners, a suction head and a brush therein, in combination with a dust guard pivotally mounted on said head at the rear and bottom and extending below the bottom and across the front thereof, and a iiexiblc guard-strip at the rear and bottom of said head and hood extending downward flush with said dust guard.

In testimony whereof we aiiix our signatures in presence of two witnesses.
