To all whom '2'! may concern:

Be it known that 1, WILLIAM H. HALL, a citizen of the United States, residing at Cicero, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Suction Devices, of which the following is a specification.

This invention relates in general to tion devices, and more particularly to cleaners for cleaning rugs, carpets, etc., when on the floor, and one of the primary objects of the invention is the provision of a cleaner of this general character comprising a suction cleaning device for removing fine dlrt, dust, etc., from the floor, and a revolving brush adapted to. collect thread, lint and other objects which are not readily picked up by the suction device. 1

A' further object is the provision of ,a novel and improved suction device which is' separably mounted on the main frame of the machine and may be swung back to permitthe removal of the suction dust-pan, the brush and itscollecting pan, and may be swung down over the top of the frame to form a cover for the machine and effect a hermetic connection between the suction nozzle and the suction device.

Other objects and advantages of the presa perspective view of a cleaner embodying my ,invention'showing the suction device separated from the main frame of the machine and tilted partway back; Fig. 2 is an enlarged fragmentary elevation showing the suction device tilted back to its extreme position; Fig.3 is a rear view of the ma-. chine, part of the casing being broken away to show the interior thereof; Fig. 4 is a sectional view taken substantially on the line 4 l of Fig. 3; Fig. 5 is a perspedtive view of the brush pan, and Fig. 6 is a fragmentary sectional view through one of the rear corners of the machine.

Referring to the drawings, 6 designates generally the mainframe of the machine constructed to provide an open-top air chamber 7, and a nozzle 8 at the front of the machine having a channel or passageway 9 communicating with the air chamber 7. A

dust-pan 11, preferably constructed of tin or light sheet metal, is adapted to set loosely in the air chamber 7 andto receive the dust and dirt drawn in through the nozzle passageway 9, A screen comprising a frame 12 and a suitable fabric 13 stretched thereon is adapted to be positioned iii'the main frame 6 directly over the pan, as shown in Fig. 4, the air chamber 7 being provided adjacent its open top aperipheral ledge or shoulder 14 upon which the screen rests. Upon the upper edge of the screen frame there is provided a gasket 15 of leather or other suitable material which projects from the perimeter of the screen and overlies the upper edges of the dust chamber walls, the gasket being adapted to afford a hermetic connection between the air chamber and the air pump in a manner whichwill be later described.

Each rear side wall of the frame 6 has a bracket 16 secured thereto, saidbracket being-bent inwardly at the end of the frame and then 'rearwardly as shown in Fig. .6,

so as to project beyondthe frame in position to recelve a transversely extending shaft 17 upon the ends of whichare mounted the driving wheels 18, by means of which the rear end of the machine is supported- The Patented Sept. 9, leis.

front of the machine rests upon the noz- I zle 8, andfthe machine is caused .to travel back and forth upon the floor or other s rface being cleaned by a suitable handle 1 9- connected with a bail 21 pivotallyattached to each side of the main frame.

Suction is' induced through the nozzle 8 by means of'a suitable suction device or a pump, onexp'ra tical form of which is shown in Flgs. 1,- 3 andA. This pump comprises afiat base 22 prfivided at its rear end with downwardly projecting brackets 23 supported on the shaft 17 adjacent the brackets 16. The pumpbase therefore has a hinged connection with the main frame of the machine which permits the pump to be closed down over the frame in the position shown in Fig. 4, thereby forming a cover therefor. A suitable gasket 24 is preferably provided on the lower face of the base member to cooperate with the gasket 15 on tlie screen frame to effect a. hermetic connection be tween the pump base and the air chamber lows consists of a stationary bottugmtmem-- her or plate 26 secured to the base member 22, a stationary top member or plate 27 rigidly attached to themember 26 at the nose of the bellows by a block 28, and a movable intermediate member 29. The rear ends of the members 27 are supported in elevated position by straps or braces 31 fixedly secured at their lower ends to the members 26 and at their upper ends to the members 27 The intermediate member 29 is hinged-to the block 28 preferably by a 2-ply leather strap or sheet 32 which extends throughout the width of the bellows, and has its projecting ends 33 and 34'secured to-the sides of the members 27 and 26 respectively to insure an air-tight partition between the two air chambers of each bellows. The sides and rear end of the member 29 are connected with the members 26 and 27 by any suitable flexible material 35 adapted to collapse and permit up and down. movement of the member 29 betweenthe members 26 and 27. The rear end of each member 29 is I connected with its respective driving wheel 18 by a pivoted link 36, which upon rotation of the wheel swings the member 29 up and down about the leather hinges 32.

The lower chamber of each bellows communicates with the air chamber 7 in the main frame through an aperture 30 over which is positioned a valve consisting of a pair of metal disks 37 embracing a flexible disk 38' of leather or other suitable material. A spring 39 affixed to the member 26 by screws 41 or other suitable fastening means projects over the valve and is provided near its end-with an aperture which fits loosely over a stud 42 projecting from theupper face of the valve. The valve is thereby yieldingly held in operative position, and may be removed when occasion requires by simpl lifting the free end of the spring 39 out o engagementwith the stud 42, whereupon the valve may be readily removed. Theexhaust valves 43 for the lower chambers are substantially similar to the inlet valve, and cover the exhaust openings 44 in the base of the bellows. Near the nose 1 of the bellows the members 26 and 29 are provided with alined openings 45 and 46 which are connected by a collapsible tube 47 through which communication is established between the air chamber 7 and the upper chamber of the bellows. -The tube 47 may be constructed of any suitable material, and is affixed at'its ends to the members 26 and 29 in any approved manner. An .inlet valve 47 and an' outlet valve 48 permit ingress bellows base 22, this casing being adapted to afford protection to the bellows give the machine a neat and rounded appearance. Fromthe foregoing it will be understood that when the machine 'is run back and forth across a floor or carpet the dust will. be

drawn into the air chamber through the nozwhich is adapted to pick up and collect material ofthis character. The brush designated by 49 may be of any preferred construction, and has pintles 51 projecting from "the ends thereof and adapted to revolve in suitable slotted bearings formed in the brackets 16. In some instances it may not be desirable to use the brush, and in order that it may be readily removed when not required, or for the purposes of-cleaning, the

slots52 formed in the bracket 16 are open at their upper ends to receive the pintles 51, and are provided at their lower ends with disposed when the brush is in operative po I an offset portion 53 in which the pintles are 'sition. In order to yieldingly hold the brush in position I prefer to recess the side members of the frame as indicated at 54 and to dispose a suitable leaf spring 55 in each recess which normally and yieldingly retains the pintles-in the position shown in Fig. 4. It will be obvious that by simply moving the brush tothe left, viewing Fig. 4, against the force of the springs it may be readily lifted out of the slots and removed from the machine.

A collectin' pan 56, shown in Fig. 5, is made prefera ly of sheet metal and formed to removably fit down over the brush and provide collecting pockets 57 and 58 at each side of the brush in which the material taken up by the brush isdeposited. It will be observed that the construction of the machine frame afi'ords suflicient space. on eachside of the brush to accommodate a dirt-receiving pocket, thereby providing a repository for the rece tion of'the material'collected by the .brus irrespective of the; direction of travel of the brush. This pan is equipped with .--projecting portions 59 at the ends adapted to rest upon the main frame of the machine and support the pan in operativ position. When the bellows are turned been into inoperative position, as shown in Fig.

2, the pan 56-may be. readily lifted out and dumped. An openingfil is provided in the chin the screen '13 is u'siially lifted out .the pan G dumped into. the pan 1'1,.'Where upon all of the refusemaylbedisposed vot 111g it.
