"A The present invention relates to suction cleaners in general and particularly to a suction cleaner provided with new and improved electrical connections. More specically the invenl tion comprises a new and novel cleaner structure embodying a conductor cord take-up. It is an object of ythe present invention to provide a new and improved suction cleaner. It is another object of the invention to provide a suction cleaner embodying improved electrical connections. Still another object is to provide. a suction cleaner with an automatic cord take-up. A still further objectof the invention is to provide a suction cleaner in which the conductor cord take-up is carried by the body proper of the cleaner. Still another object of the invention is to provide a suction cleaner in which manually operable means controlled by the operator causeA the electric conductor to be wound vupon a reel concentric with the axis of the driving motor. These and other more-specii'lc objects will appear uponv reading the following specication and claims and upon considering in connection therewith thev attached drawings to which they relate. Referring nowA to the drawings in which pre-` ferred embodiments of the present invention are disclosed:

Figure 10 is a partial section upon the line Ill-I0 of Figure 9;
`Figure 11 is a diagrammatic illustration of the electrical circuitcommon to both embodiments .of the invention.
Suction cleaners are generally unprovided with means `to accommodate the elongated conductor i' cord-necessary to connectthe cleaner to a source of current other than simple winding posts upon 'the handle on -which the cord can be wrapped.
In. a few'cleaners cord take-ups have been embodied in thefhandle structure. Such take-ups, either hand operated or lmotor operated, have been objectionable'in that their weight has been excessive and, through being positioned on the handle, that weight has been transmitted to `the operator who holds the upper end thereof.
`I the limproved cleaner constructed in accordance with the present invention the objectionable features of the earlier prior art structures have been eliminated through the incorporation of the cord take-up 'into the body proper,` of the cleaner. The cleaner constructed in ac` cordance with the present invention combines an improved cleaner construction with a novel arl rangement of a cord take-up in a manner which necessitates a minimum of parts and which results in a functional operation not heretofore known. By positioning the cord take-up concentric with the motor axis, about which the handle also pivots, and by having the motor casing as well as the cord take-up casing rotate and pivot with the handle, a compact and completely eflicient cleaner has been produced.
Referring again to the drawings 'and to Figures 1 to 7, inclusive, in particular, the rst preferred embodiment of the invention is disclosed. A chassis, comprising a nozzle l with rearwardly and 'upwardly extending passageways 2, 2 at the sides indicated at l2, I2, etc., are provided at each of the `ioints and appearance plates I3, I3 carried cover plate I6 is provided in the opposite passageway 2 which gives 'ready access to the driving belt positioned therein, as will be hereinafter set forth.
At the opposite end from the fan chamber I4 the motor-fan casing I is interiorly provided with a'motor housing 20 which comprises the stator of the motor and which carries the field windings 2|. Housing 20 isformed with an extended hub portion 22 which reaches to the inner side wall of fan chamber .I4 for a purpose which ,will hereinafter become apparent. 'I'he outer side wall of motor `housing 20 is formed by the enclosing motor-fan casing I9 side wall II, the side wall and the housing being secured together by removable screws 23, 23, etc. g
' The motor armature 25 is mounted uponfthe rotatable shaft 26 which is supported by bearings 21 and 28 located at the motor housing outer wallII and at the inner wall of the fan chamber- I4. Shaft 26 extends through, and is housed by, the extended hub portion 22 of the motor casing and within the fan chamber I4 it carries the suction-creating fan 30. At its opposite end it extends through the supporting bearing 21 into the adjacent passageway 2 where it carries a belt pulley 3| to which is connected a belt 32. Belt 32 extends down the` passageway 2 into the nozzle I where it rotates in a common and well known manner a rotary agitator the lower surface-contacting elements of which can be seen in Figure 5. The agitator is indicated by the reference character 33. Pulley 3| iS Opposite the removable cover I6 thereby permitting easy attachment and detachment of the belt.
Positioned axially at one end of the motor casing 20 and between the latter and the fan chamber |4 is a cord reel 35 which is within the radial peripheral dimension of the motor casing 20 and is mounted for independent rotation upon bearings 3I,r 36 carried by the extended hub 22 of motor'casing 20. The cylindrical seat 31 of reel 35 is spaced at a considerable distance from the supporting hub 22 and encloses a coiled flat spring 40 the inner end of which is fixed to the hub 22, through being inturned to seat within a slot 4| formed in that hub,y and the outer end of which is suitably fixed to the cylindrical seat 31. upon the reel 35 which is clockwise when viewed from the motor end of the casing I0.
One side wall of cord reel 35 includes a section 42 formed of suitable insulation material such as Bakelite Inset in the outer surface v of this insulation are .concentric rings 43, I43 of current-conducting material the terminals of which extend to the inside of the'reel where the leads 44, 44;:of the conductor 45 are attached. A third lead 41 grounds the reel 35 and the cleaner. The conductor extends from the terminals through an opening 46 in the seat 31 to encircle that element.
Stationary wiper contacts 59. 50 are mounted upon the inside wall of motorcasing adjacent the cord reel, one for each of the conducting rings 43 and suitable leads 5|, 5| convey the cur- The motor fan casing |0.additionally includes an exhaust outlet 55, a handle socket 56, and a slot or port 51 for the conductor 45. The usual suction cleaner handle 58 removablyseats within the socket 56 where it is held by a screw 59, leads 5I, 5I extending upwardly therethrough to a manually operable switch 6| so that the circuit through the/machine can be opened and closed. The upper end of the handle supports a dust bag 63 which is removably attached to the exhaust outlet 55 in a common and well known manner. a
'I'he upper end of the handle is also provided with a cord controller which comprises two apposed spring-pressed eccentrics 66, 66 formed .with knurled lever portions 61, 61 which extend outwardly through the controller casing 65. The
`rent from the wiper contacts to the motor and to other parts of the machine.
conductor passes directly through the controller housing through openings 68, 68 whichare curved and rounded to prevent injury to the conductor surface. The conductor is of such width and the eccentrics 66, 66 are so positioned that the spring action of the eccentrics tends to clamp the conductor therebetween. This clamping action is increased by the downward pull exerted upon the conductor by the spring 40 which tends frictionally to rotate the eccentrics. A pressure exerted upon the levers 61, 61 forcing them together functions to rotate the eccentrics 66, 66 in a direction to move them'away from the cord 45 and to permit that element to be drawn toward the machine under the impetusimparted to the'reelby the spring 40. The cord can continue to wind upon thereel 35, in the manner illustrated in Figure 3, until such time l as the plug 69 at the outer end of the conductor contacts the controller housing 65.
The electrical circuit of the machine is perhaps best understood by reference to Figure 11 which comprises a diagrammatical illustration thereof. The incoming leads 44, 44 of the conductor 45 are shown attached to the rotatable. a rings 43, 43 which are contacted by the motorcarried wiper contacts 50, 50. The handle switch 6| is in series with one of these contacts through the leads 5|, 5I extending through the handle thereto and back. The motor eld windings 2|. 2| and the armature 25 are shown in the circuit and the switch 6| is seen to control the flow of current through the eld windings and armature of the motor. r
The operation of the cleaner constructed in accordance with the present embodiment of the invention is quite simple. With the plug 69 at the outer end of cord 45 attached to an outlet the machine is ready 'to be operated. The conductor 45 has been drawn out to the necessary length without depressing the levers 61, 61 for the `frictional force exerted by the moving cord 45 pivots the eccentrics 66, 66V into non-clamping relationship. With the plug connected the motor switch 6| is closed and current passes to the motor in the manner described above in connection with the electrical circuit illustrated in Figure 11. In the cleaner operation the angudar position of the handle 58 relative to the cleaner chassis will change and Ithis angular adjustment is accomplished by the rotation of the motor-fan casing I0, together with the fan chamber I4 and motor housing 20, about the axis of the casing pivots.
the motor which is concentric with the pivotal axis formed by the bearing plates 6, 6 upon which In'this pivotal movement of the handle there is no relative rotation between the reel 35 and the motor or fan housing, the entire structure pivoting as a unit.
Uponthe conclusion of the. cleaner operation it is desirable to store the length of the cord. The plug 69 at the outer end of cord 45 is disconnected and the operator compresses the levers 51, 31, immediately the coilspring 40 causes the reel 35 to rotate and the conductor 45ft0 be drawn into the casing I and to wrap thereabout, in the manner illustrated in Figure 3. The movementof the cord back and forth across the reel is a natural result and is permitted without and 11 have been provided whichV are mounted adjacent the reel 35 and adjacent the end of the cord port 51 and which serve to guide the conductor 45 from the central position on the casing at which it enters the port to a position adiacentthe center of the reel 35 so that it naturally winds back and forth thereon as the reel rotates.
The operation of this form of the invention is functionally the equivalent of that first described and the control means at the upper end of the handle is identical in both. embodihindrance by the elongated opening 51 through l which the conductor enters the casing. The current is conducted to the electrical circuit of the motor in all angular positions of the reel as the wiper contacts 50, 50 at all times connect the conductor 44, 44 to the motor leads.
Referring nowto Figures 8, 9, and 10, a second preferred embodiment of the present invention is disclosed. Functionally this embodiment is very similar to that first described but diiiers therefrom in the arrangement of the parts. According to this embodiment the fan chamber I4 is positioned as in the first embodiment but the motor casing no longer uses an outer wall Il of the motor-fan casing l0 as a side wall; it has instead been shifted over to a point immediately adjacent .the fan chamber.
` The conductor take-up in this embodiment is positioned axially at one end of the motor housing and within the radial peripheral dimension of the latter and not between the motor and the fan chamber as in the first embodiment.
In this second embodiment the armature of the motor is again carried by the motor shaft 26 which also supports the suction-creating fan in the fan chamber I4. The shaft itself is rotatably supported in the bearings 12 and 13 which are carried by the side Wall 14 of the motor housing 20 adjacent the fan chamber and by the elongated hub 22 at the opposite side of the motor which in the pres-ent embodiment has fbeen enlarged in diameter to house the bearing 13. As in the iirst embodiment the end of the motor shaft 26 opposite the fan 30 carries the pulley 3| which seats the power-transmitting belt 32.
The cord..takeup constructed -in accordance with the second embodimentis quite similar to that of the first embodiment in that the reel is rotatably carried by sleeve bearings 36, 36.
upon the extended hub 22 of the motor casing, and in Athat the insulation side 42 of the reel is again provided with the ring contact plates 43, 43 which contact the wiper contacts 50, 50 carried by the motor casing. The actuating spring of the reel, however, is in this embodiment positioned at the side of the reel where its size is not restricted by the internal diameter ofthe cylindrical seat 31. 'Ihe spring is fixedly secured to the hub 22 as illustrated in Figure 4 in connection with the rst embodiment, and is secured to the reel 35 by an enclosing flange 15 which is fixed Ato the reel and by which it is enclosed. Spring 40 performs the function in this embodiment, as in the first em'- bodiment, of rotating the reel to wind the cord conductor thereon.
Because of the oil-set relationship of the reel 35 With respect to the handle, guide pulleys 16 vIneIltS.
