11 Claim.
The present invention relates to suction cleanera in general and more particularly to a new and improved casing construction for suction cleaners. More specifically the invention comprises a new and novel fabricated cleaner casing which is of greater simplicity and structural strength than those heretofore known.
it is an object of the present invention to provide a new and improved suction cleaner. It is another object of the'invention to provide a new and improved suction cleaner casing. A further object of the invention is to provide a suction cleaner casing parts of which may be die cast or stamped and which interfit to provide a simplified stronger structure. Still another object of the invention is to provide a suction cleaner casing which forms an air passageway, a fan chamber and a motor housing, and which comprises two main separable parts which are readily die castwlthout the use of side cores. A still further object of the invention is to provide a suction cleaner casing in which an upper casing portion forms the nozzle, the motor cas-,
ing, the fan chamber upper section, and the top of the air passageway leading from the nozzle to the fan chamber, while the lower casing portlon forms the rear lip of the nozzle, the bottom wall oi? the air passageway, leading from the nozzle to the fan chamber, the bottom portion of the fan chamber, and the side walls of the exhaust passageway. A further object of the invention is to provide a suction cleaner in which the cleaner casing-is formed of a plurality of interiitting parts which between them seat the driving motor and suction-creating fan which is removable upon the separation of the parts which are of extreme simplicity. These and other more specific objects will appear upon reading the following specification and claim and upon considering in connection therewith the attached drawings.
Suction cleaner casings may be made in many ways. They may be fabricated from sheet metal or they may be formed of die castings. They may be assembled from a plurality of parts which are designed to seat one upon the other or they may be simply made of a few simple structural forms which cooperate to provide a complete cleaner casing and which is disassembled with the removal of a minimum of securing means. It is to the latter type of construction that the present invention relates.
Referring now to the drawings in which preferred embodiments of the invention are disclosed:
Figure 1 is a side view, partly in section, of a suction cleaner constructed in accordance with the first embodiment of the invention:
Figure 2 is a section through the motor and. suction-creating fan upon the line 2-2 of Figure 1;
Figure 3 is a front view of the cleaner illustrated in Figures 1 and 2 with certain parts of the nozzle wall broken away;
Figure 4 is a view in perspective of the bottom portion of the cleaner casing in disassembled re latlonship;
Figure 5 is a side view of a second embodiment of the present invention with certain parts shown in section;
Figure 6 is a bottom view of the cleaner con structed in accordance with the second embodi ment of the invention;
Figure '7 is a View through the driving motor and suction-creating fan upon the line 'l--'l of Fi ure 6.
The cleaner constructed in accordance with the present invention embodies the usual cleaner parts comprising a nozzle l, a fan chamber 2, which houses a suction-creating fan 3, and which is connected to the nozzle l by means of the air passageway 44. A motor housing t contains a driving motor I, the shaft 8 of which carries the suction-creating fan 3 within the fan chamber 2 and is extended into the air passageway 4 where it carries a belt-driving pulley 9. An exhaust passageway ll extends rearwardly from the suction-creating fan chamber 2 and has detachably connected to its rear end by manually releasable securing means l2 a dirtfiltering bag l3. Within the nozzle l is posi" tioned a rotary agitator it of a well known type which includes rigid beating and flexible brushing elements and which is itself actuated by a power-transmitting belt it which is connected at its opposite end to the driving pulley 9. The driving motor 1 is seen to comprise an outer shell or casing ll which carries the stator it. The rotor I9 is rotatably carried by the shaft 8 in end bearings it, it.
Front and rear supporting wheels 22 and 23 are positioned below the cleaner and movably support it while, as in the usual cleaner construction, a handle 24 is pivotally mounted upon a supporting bracket 26 Positioned upon the exhaust outlet II and provides means by which the machine may be propelled in use. I
In the cleaner constructed in accordance with the present invention as illustrated in Figures 1 to 4, inclusive. the top, front and side walls of the nozzle I, indicated at 3!, 32 and 33, the rear interior wall indicated at 34, and the top and side walls it and 31 of the air passageway I are formed integrally in the top body portion of the cleaner casing. Also formed integrally therein are the upper sections of outer side walls 39 and 4. and the common dividing wall 44 of the motor casing i and fan chamber 2. Also formed therein are the top walls I" and 43 of the exhaust passageway H and fan chamber 2. The bracket 2! which carries the pivoted handle 24 is preferably a separable element secured to the wall II in any suitable manner. The common upper wall section 44 of the fan chamber 2 and the motor casing 6 extends downwardly to a point slightly below the dividing plane X--X, illustrated in Figure 1. An abutment shoulder 46 is formed on wall section 44 and extends into casing 6 to support a threaded screw 41 which positions the motor casing body portion. The top of the cleaner casing is completed by a curved appearance wall 48 which extends between the outer motor casing and fan chamber walls 39 and 40 to form the top of the motor casing 6, being removably secured at its rear side to the top of the exhaust passageway wall 4| by a removable screw or screws 49.
Cooperating with the top body portion of the cleaner casing is the bottom body portion or section illustrated in its entirety in Figure 4 and which is seen to form the entire underside of the cleaner body. The front extremity of this body portion extends horizontally and forms the rear nozzle lip 5|. The surface rearwardly of lip 5| to the raised shoulder portion 52, forms the bottom wall of the air passageway 4 and is indicated by the reference character 53. Side walls of this body portion, indicated at 54, 54, define openings 65 in which the front supporting wheels 22, 22 are positioned. This bottom casing section is formed immediately below the motor and fan with spaced vertical wall sections 51, 58 and 59 between which extends a common bottom wall surface 6| having several elevations adapted to accommodate the mechanism of the cleaner. The space defined by the vertical walls 5'! and 58 and the bottom wall it forms the lower portion of the motor casing 6. The space between the walls 58 and 58, together with the bottom wall 6| therebetween, forms the lower portion of the fan chamber 2, and rearwardly of the fan chamber where they extend belowv the wall 4|, they form the side walls and bottom wall of the exhaust passageway II.
The upper and lower cleaner casing sections are adapted to be secured together by a plurality of vertically extending screws or bolts which are not illustrated but which are adapted to pass upwardly through the bottom section through the seats 63 to be suitably-seated within the upper casing section. One of these securing screws may be seen in Figure 1 and is indicated there by the reference character 84.
It has been said that the cleaner body is formed of the two casing sections and this is substantially true but with the exception that the air passageway 4 between the nozzle I and the fan chamber 2 is actually completed immediately adjacent the eye of the fan chamber by a removable is desired to disconnect the belt or to replace it.
This simple construction comprising two main pieces is one which can be easily manufactured by die casting or stamping processes and is simple, durable, rigid, and economical to manufacture. The driving motor and fan are secured in the upper half of the body and are removable therefrom simply by removing the cover plate or shell 48 and manually removing screws such as indicated at 41, the bottom half of the casing being previously removed as permitted by the removal of the screws 64. Suitable seals, as indicated at 68, are preferably provided to seat the motor in its place in the body and to seal the fan chamber where the shell ll abuts the fan chamber side of wall 44.
Referring now to Figures 5 to 7, inclusive, the second preferred embodiment of the invention is illustrated and includes the same functional parts as in the first embodiment and those parts are here indicated by the same reference characters. Several distinctions exist between this embodiment and the first embodiment, however, and these comprise the elimination of removable curved shell 48 which formed the top of the motor casing in the first embodiment and the forming of the top wall of the motor casing integral with the side walls thereof and as a continuation of wall 43 which forms the top of the fan chamber. It is also to be noted that in this embodiment the top wall 4! of the exhaust outlet II has formed integrally with it a part of the side walls thereof where in the first embodiment the entire side walls were formed in the lower casing section.
As in the first embodiment the upper and lower casing sections are secured together by vertical screws 64, but it is tobe noted that the motor shell I! of the first embodiment, which carried the stator l8, has been eliminated and instead the motor stator I8 is carried directly by the lower casing section to which it is secured as by screws H. The supporting bearings 2| of the armature l9 are likewise mounted in and between wall sections formed in the upper and lower half of the casing. In disassembly of this embodiment of the invention the motor and suction-creating fan will come away from the upper half of the casing with the lower casing section as distinguished from the first embodimerit.
The handle in this embodiment is pivoted at the sides of the exhaust passageway ll rather than upon a bracket 26 upon the top of that outlet as in the first embodiment. Also, the removable pulley cover 66 of the first embodiment has been eliminated and the walls thereof are formed integral with the top and bottom sections of the casing. A change of appearance is brought about by the extension of the wheelpocket-forming side walls 54 rearwardly substantially to the end of the casing, or more specifically to a point rearwardly of the eye of the fan chamber. As in the first embodiment the two major sections comprising an upper top section and alower casing section which make contact in arearwardly and upwardly inclined plane here denoted by the letters Y-Y as illustrated in Figure 5, and the upper and lower casing sections cooperate to complete the cleaner in substantially the same manner as described in connection with the first embodiment.
As to features of assembly and disassembly and the inherent strength of the device, the second embodiment of the invention is quite like that described in the first embodiment and it is believed that the construction will be readily understood from a comparison therewith.
I claim:
In a suction cleaner of the type having a suction nozzle, an adjacent motor casing and vertical fan chamber with their principal axes aligned and extended parallel to the nozzle, an air passageway between said nozzle and fan chamber, and an exhaust outlet which extends rearwardly from the underside of said fan chamber; an integral upper casing section which forms the front lip, front, top and side walls of said nozzle.
the top and side walls of a portion of said air passageway, the side walls of the upper portion of said motor casing, the top and side walls of n the major portion of said Ian chamber, and the said motor casing.
