Specification of Letters Patent.

Application filed November'll, 1912. Serial No. 730,663.

and has for its, object the provision of a suction cleaner of novel construction, pro- I vided with a nozzle having a plurality of longitudinal suction-openings of diiferent widths which are spaced apart crosswise of said openings, the said nozzle forming a base which supports a fan and. motor-case in upright relation; further the provision of a suction cleaner in which the nozzle forms a support for the motor and fancase and in which the motor-case, fan-case and suction-nozzle have substantially coincident u right axes; and further, the provision 0 a suction cleaner of novel and comact construction; and the invention will e further readily understood from' the following description and claims, and from the drawings, in which latter: Figure 1 is a side elevation of my improved device, Fig. 2 is a plan view of the same with the handle partly broken away. F' '3 'is'a vertical section of the same on t e line 33 of Fig. 2. Fig. 4 is a rear elevation of they same with the handle and separating be removed. Fig. 5 is a horizontal section 0 the same on .the

line 5 -5of Fig. 4. Fig. 6 is a vertical sec-' tion on a line similar to the line 3-3 of Fig. 2, showing a substitute cleanin tool attached to the fan-case; and, Fig. is a vertical section of the same on the ine 7 7 of Fig. 6

The suction in my im instanced as created by a; an 11, which rotor '19 supported in a motor case 20, the motor-case being'shown supported on thefan-case and instanced as 1npart sursleeve 22 are received, the construction bein roved device is rounded by a sleeve integral with the fancase.

21 is a nozzle or suction-head having'a' sleeve 22 received about a sleeve 23 rovided with inclined faces 24: against w ich the ends of screws 25, threaded into the such that when the screws are screw against said inclined faces the sleeve 23 will vbe urged lengthwise of the sleeve 22 for forming a tight joint 26 between the nozzle and fan-case. ,The nozzle has a chamber 27 therein which communicates with the chamber 28 in thefan-case by means of the passage 29 through said sleeves, the center of longitudinal rojection of said chamber in the nozzle and said passage being preferably coincident with the axes of rotation of the armature-shaft and. fan. I-prefer to provide the nozzle. with a lateral extension 30 at. each corner thereof for forming supports for the nozzle and the superposed fan-case and motor-case, insuch manner that the parts will stand alone and not tip, whereby the nozzle and superposed parts may bereadily moved across the surface to be cleaned with a minimum of exertion. The outer ends of said extensions at each side of the nozzle are connected b a bar 31in which a'roller 32 is journale on a pin 33 Patented July 21L, T291142 located in bearings 34 in said bar. I prefer to provide the suction-nozzle with a plurality of longitudinally extending suctionopenings or slots 37 38, each coincident with a pair of said extensions 30, these suctionopenings being spaced apart crosswise of said openings, that is, side by side, and one of the openin s being of greater width than the other. T e suction-opening 31 has an outer longitudinal wall 39 and an inner longitudinal-wall 40. The suction-opening 38 has an outer longitudinal wall ll'and an inner longitudinal wall 42. The lower end of one'of the longitudinal walls of each of LZLIu S1JlClLl0I1-0PBI11I1ES, when the suction-nozzle 1s 1n 0 erative relation with the surface of the inner walls 40 and 42, which are shown' hi her than the lower ends of the outer wal s 39 and 41', whereby inlet spaces .445, 45, into the chamber 27 through and respective openings are insured. I prefer toprovide a brush 46, shown as a rotary brush, in the wider of these suction-o enings. The brush is on a shaft 47 located in bearings 48 in the end-walls of the suction-opening. The brush is provided with a flexible portion 49, preferably made of bristles. The rollers are located between the suction-openings and are so placed that the suction cleaner will normally ride upon said rollers and one of the walls of said suction-openings or said brush when passed over a hard surface. The

rollers are preferably placed in the vertical.

plane of the center of gravity of the motorcase, fan-case and suction-head, so as to relieve the friction of the deviceon the surface being cleaned and the adhesion of the device to said surface caused by the suction,

whether said surface be hard or of a soft or-fabricnature. When the suction cleaner 1S supported on the surface being cleaned,

the bristles will normally bend upon said surface. The brush is of such diameter and relation relative to the width of the suctionopening as to provide longitudinal spaces between the periphery of the brush and the walls of said opening. The lower wall of the chamber 27 is preferably arched as shown at 50 and located above the plane of the surface 43 being cleaned when the device is in operative relation for providing a substantial draft space, leading to the inletspaces M, 4-5, into the suction-openings. I

-The handle 16 by meansof which the cleaner-head is moved across the surface being cleaned, in its preferred form is pivoted or clamped to the case by means of a bolt 52 passlng through the lower end of said handle and a lug 53 on the case.

The construction of the suction-cleaner is such as to permit the same to be moved across the surface to be cleaned without danger of tipping the same, thereby rendering the same easy in operation. The device is preferably so arranged that the opening having the brush in coaction therewith is at the forward portion of the device, the narrow suction-opening being in rear of the former whereby, in operation, in passing the apparatus across the surface to be cleaned, the said surface is first brushed for loosening the particles of dust that may be therein, the lar er particles being swept and sucked into said forward opening, the latter being followed by the narrower opening for sucking up the final particles of dust and dirt and presenting an especially clean surface.

The suction-nozzle is shown removable,

= and if desired, other suction-tools may be sustituted in place thereof and secured in similar manner to the sleeve of the fan-case;

I have shown such a tool in the form of a suction-nozzle 55 having a single opening 56 J with a brush 57 therein, a roller 58 being located ateach end of the brush. 7 The rollers said slots, and supporting rollers between said slots and extending below the face of said suctionrhead wherebysaid suction-head is rochingly supported.

2. A portable suction cleaner comprising a suction-head having-a plurality of suction-slots spaced apart, a brush mounted inand projecting from one of said slots and supporting rollers located between said slots and projecting below the lower face of said suction-head.

3. A portable --suction cleaner comprising a suction-head having a plurality of suctionslots provided with walls extending longitudinally at the sides of said respective slots,

one of the walls of each of said slots being higher. than the other of said walls thereo when said suction cleaner is supported upon the surface being cleaned, and rollers at the the ends of'said slots rockinglysupporti suction jcleaner .upon; the surface eing cleaned. i

4. A portable suction cleaner comprising a suction-head having a pair of suction-slots at its bottom spaced apart and located side by side, each of said slots provided with walls extendinglongitudinally at the sides of said respective slots, the lower edges of the adjacent ones of said walls being higher than the lower edges of the farthest distanced ones of said walls when said suctionhead is supported. on the surface being cleaned, forming inlet-spaces for said slots' presented toward each other, and an arched connections. between said adjacent walls formingghfilarched draft-space between and communicating yvith said inlet-spaces, sub.-

stantially as'described- 5. A portable suction cleaner comprising a suction-head having a narrow suction slot and a wide suction slot, said suction-slots extending crosswise 'of thesuction cleaner and located side by side and spaced apart, a suction-creating device communicating with said suction-slots, and a brush extending lengthwise in said wide suction'-slot, where-' by the .particles to be sucked are agitated, said narrow suction-slot having unobstructed connection with said suction-creating device,

for the purpose described.

6. A portable suction cleaner comprising a suction-head havingva narrow suction-slot and awide suction-slot, said suction-slots extending crosswise of said suction cleaner and located side by side and spaced apart, a

suction'creating device communicatin with said suction-slots, the lower of 6 ad'- igcent ones of the walls of said, slots being gher than the lower edges of the farthest distanced ones of said walls when said suction' cleaner is supported on the surfacebeing I cleaned, forminainlet-spaces for said slots, a connection tween :said adjacent ones 'ofsaid walls forming a draft-chamber under said suction cleaner communicating.

with said inlet-s aces; a brush in said wide suction-slot, an said narrow suction-slot having unobstructed connection with said 15;
