To all whom may concern.'

Be it known that I, FnANcrs M. CASE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Cleaners, of which the following is a specication. i This invention relates broadly to devices known as suction sweepers or cleaners, and is particularly designed as an improvement over the construction set forth in my copending application filed of even date herewith. y

The present invention relates articularly to an adjustable hood carrying the brush and arranged in a manner such that it may be raised or lowered freely to and from the surface operated upon without adjusting the forward rollers of the device, thus rendering the machine easily adjustable in point of the distance of the mouth of the hood from the surface operated upon.

The invention also resides in certain details of construction hereinafter set forth in the following description, drawings and claims.

Referring to the drawings, Figure 1 is a side elevation of the device, showing the carpet or fabric as it is drawnup from the floor; Fig. 2 is a longitudinal vertical section; Fig. 3 is a section upon the line 3-3 of Fig. 2; Fig. 4 is a bottom plan view; Fig. 5 is a View showing the manner of holding the end of the discharge receptacle or bag; Fig. 6 is a sectional view of one of the castors showing the handle journaled on the castor socket; Fig. 7 is a front elevation of the raising device secured to the hood and to the casing but with the nut and clamping plate removed; Fig. 8 is a top plan view of the guiding member secured to the casing; Fig. 9 is a bottom plan view of the clamping plate; and Fig. 10 is a side elevation of the clamping screw and clamping plate.

In carrying out the invention any preferred form and construction of parts may be employed so long as they possess the necessary characteristics, -but I have shown one form in the drawings which is highly eective in operation, and in such embodiment the device comprises a main casing 1 in the form of a fan or blower scroll, and this casing has at the rear thereof a neck portion 2 connected with an enlarged discharge member 3. The casing 1 is further` provided with an opening 4 with a finished surface 5 about the same for receiving the supporting ring 6 in the u er part vof which is mounted the motor 7. he rin 6 is provided witha downwardly rejecting flange 3 which 1s adapted to pass tiirough the opening 4 and to extend iiush with and preferface of the casing, as shown in Fig. 2, and for a purpose which will be described later. The motor 7 is provided with a vertically disposed shaft 9 having secured to it by a set screw 9 the hub 10 of a fan disk 11 provided with suitable bladesz-/lZVj-'onits'underably slightly beyond the upper inner surranged in a manner such that when it is in place the edge of the disk 11 is close to the lower edge of the flange 8, while the periphery of the disk extends to a point corresponding substantially with the outer periphery of the flange 8. The object of this arrangement is to cause the air above the disk to be discharged into the fan casing or scroll, so that the lodging of dirt above the disk is prevented. The motor shaft 9 is further provided with a driving pulley 13 for a purpose to be described. The shaft 9, the hub 10 and the pulley- 13 extend below the bottom of the main casing and through an openin 14 therein.

The main casing at the rear is supported upon two castors 15-15, each of which is provided with a shank 16 extending up into a suitable socket member 17 secured to the side of the casing and having anupwardly extending trunnion member 18 provided with a laterally extending pin 19 for engagement in an opening 19 in the corresponding end of a forked handle member 20 which is provided with a socket 21 for receiving a handle 22. The socket member 21 is provided with a pair of ears 23 for receiving a link 24 swiveled in the end of a link 25 provided with' a sea-t 26 for receiving the ears 23 when the handle is in its lower position. The link 25 is pivoted upon a pin 25 mounted inl ears 27 secured to the discharge member 3 of the casing. The forward end of the main casing is supported upon rubber-tired wheels or rollers 28 mounted upon pins 29 each secured in the sides of a housing 30 forming a part of the main casing 1. These wheels or rollers support the casing of the device and hold .itin a fixed position with respect to the floor at all times.

The operation of the motor causes the rof- Y p noce-,sra

tation ling created through the opening i4 and a discharge through the discharge member 3',

- and in this instancethe suction is utilized in conjunction with ar brush for bringing about the cleaning operation, and this mechanism will now be described, the device for receiving-the discharge being described later.

Secured to a flange 3l, which is integral with the lower portion of the main casing and is substantially ll-shaped in form, is an inlet housin 32 which conforms to the conliguration ol' the dang-e and is provided with an opening 33 in its bottom which is adapted to be lchased by a plate 34 held in place by means of a latch Yspring 35 which engagesabove the bottom surface of .the inlet housingA after-having been niet passed through notches or openings 36 in the bottom of the inlet housing, as shown 1- in liig. 4. lihe latch spring 35 is manipu f lated by a .hnurled finger piece 35 having ,a portion entending through an opening in the cover plate and secured in the spring.

The housing is still further provided with an opening 3'?, as shown in Fig. 3, in its forward end, and the lower edge of the loottom of the inlet housing at this opening is curved at 36 for receiving a corresponding curved portion 39 of a suction-.hood shanlr 46 which tapers outward in alateral direction from the inlet housing and forms a part of a suction hood 41 which is arranged besubstantially rectangular opening or mouth l 43 in the bottom\thereof, Aas shown in Fig. 1 4, and the edge of the casing about this opening is ,enlargedto form dat surfaces 44. Q At each end the hood isprovided with'a ver'- w tically disposed slot 45 which receives a slide or bloolr'46. -Each of these blocks '46 y is provided ,with a flange 47 entendin over I onto the end ofthe suction hood an` with yond'the front edge of the main casing i.-

l'his housing is pivoted so as to swing n and down at its' outer end, and this pivot is formed. by suitable screws 42 which lpass loosely through the sides of the inlet housing and into 'bosses 42 in the side walls of the hood shank.

The suction hood 4l is provided with a a vertically disposed slot 48 for receiving a brush shaft 49.. This shaftA is held in place at the ends ofthe hood by means of. suitable nuts 50 upon the enudsofthe shaft. Mounted on the shaft 49Yis'a rotary brush 5l rovided at one side of itscenter with ka p ey 52 which isadapted to be driven by a belt 53 from the pulley 13.` The movement of the hood upon its pivot is for the purpose of adjustingf-l the mouth of the hood to andA from the surface to be operated upon, as forj example, in case of sweeping doors the hoodj' is dropped close to the floor, while in swt-iep-` ing 'or cleaning carpets the hood is raised.

ofthe dan results ina= suction beso that the suction created by the fan will raise the carpet fromthe door against the mouth of the hood where it will be operated upon by the brush.

ln order to hold the hood in any adjusted position suitable mechanism is provided, and'it comprises a guide member 54- secured tothe forward end of' the main casing l and having a pair of upwardly extending danges 55 which receive between them an arc-shaJ` ed .adjusting segment 56 which is prefera ly integral with a base portion 5? secured to the hood. A- suitable fin er piece 58 is also arranged integral with t is base 57 and serves as a means for manually raising thehood, the segment 56 sliding between the dang-es 55 of the guiding member 54. The convexupper surface of the segment 56 is provided with serrations or transverse teeth 59 which ooperate with a serrated bloch 60 which is provided with an opening 6l for the passage of the shank 62 of, a thumb screw 63 which is threaded into the guiding member 54. By this arrange-'i4 ment of serrated segment and block the hood may be held in any desired position relatige to the door.

The' discharge member 3 is provided with *l an Vannular dange 64 and with -diametrically opposed ears 65, the latter having suitable 1clamping screws 66 pivoted therein.

Rachi' of these vclamping screws is provided with a clamping nut 67. The annular dange 64 is arranged at a slight distance from the outer edge 0f the discharge member so that the latter may receive a ring 68 nii a dirt-catching receptacle or bag 69 which -is .secured upon this ring at its edge so that a mouth is formed corresponding in size to the exterior of the discharge member 3. This ring 68 at the mouth of. the dis# loop 71 which` is passed over the handle before the receptacle is secured in lace.

- ln voperation the user adjusts 't e hood so that its mouth is 'at the proper distance 'from the :surface to 'be operated. upon and the motor is. started, 'when atmospheric air will beidrawn atthemouth of the hood and discharge into the receptacle 69, all the dust andv dirt' being Vdrawn from the surface jroo los

'treated and being conveyed with the air into the receptacle.` Since the receptacleis made of a fabric2 the air passes through and the dust and dlrt is collected wit the 'same from whence it may be discharged in any suitable manner.

A suitable guard is provided for the brush and it comprises abar 72 arranged near the` forward end of the suction hood on the inside and at the inlet opening and having secured in it suitable fingers 73 extending across the inlet opening or mouth thereby preventing the surface-covering from being drawn into the suction hood.
