Application February 8, 1946, Serial No. 646,239
- cleaning carpets, floors, furniture and other surfaces suitable for cleaning by suction.
Many of the suction cleaners now offered to the public are difficult for the housewife to handle, and are cumbersome and bulky, making it very difiicult for the housewife to operate the device with a minimum of time and eifort. Also the general arrangement of many devices of this character is such as to make it difficult to design-an efiicient suction cleaner.
One of the object of my present invention is to overcome the aforesaid difiiculties by providing a compact suction cleaner constructed and arranged to facilitate efficient cleaning by suction with a minimum of time and effort.
Another object of my present invention is to construct an improved suction cleaner appliance by providing a compact structure provided with improved supporting means for supporting the nozzle arm of a hose assembly and including an electrical switch which may be readily turned off" or on by the operator with a minimum of effort.
For more detailed understanding of my invention reference may be had to the accompanying drawings illustrating in detail the many novel features and the improved arrangement and detail construction of my suction cleaner, in which like characters refer to like parts throughout the several views, and in which Fig. l is a plan view of a suction cleaner appliance constructed substantially in accordance with my invention;
Fig. 2 is a side view thereof Fig. 3 is a vertical longitudinal sectional view through the appliance and taken substantially on the line 33 of Fig. 1;
Fig. 4 is a detail view of the switch mechanism as taken substantially on the line 44 of Fig. 2 but showing the nozzle and some of the parts in a different position from that of Fig. 2; and
Fig. 5 is a detail plan view showing the switch arm moved by the nozzle arm support to an on position.
The suction cleaner appliance illustrated in detail in the accompanying drawings consists of a casing A constructed to provide the substantially cylindrical compartments l0 and II which are substantially arranged to lie in parallel relation side by side having longitudinal axes which extend substantially vertical and normal to the floor line l2. Swivelling supported rollers l3 preferably support the casing so that same may be readily moved about the floor in any desired direction.
It will be noted that the casing A is illustrated in plan in Fig. l, and it will be noted that the compartments I0 and II are each provided with an open end I4 in the top wall of the casing A, and associated with each of the openings M of compartments l0 and II, are the adapter plates [6 and I1 respectively. The adapter plate I1 is substantially a ring and provides a seal for engagement by the hinged cover l8, said cover being hinged to the casing as at [9. The adapter plate I6 is provided with an opening 9 while said hinged cover I8 is provided with anopening of substantially the same diameter as opening' 9. A hose connection or fitting 2! is adapted to be secured in place with either of the openings 9 or 20.
The separate compartments [0 and II are provided with openings and 26 respectively at their lower ends which communicate with a transverse passage or conduit 21, thereby placing said compartments in open communication with each other. A motor and fan assembly is supported in compartment [0 and comprises a motor 28 operatively connected to drive a standard suction fan 29, and is operable to cause a circulation of air through the appliance substantially in the direction as indicated by the arrows 30.
The casing carries an electrical connection 50 having contact points 5| for connection with a source of electric supply, and the switch 52' is wired by means of electric cables 53 to the con-- nection 50, the cables 54 leading from the switch 52 to the motor 28.
Said switch 52 is provided with a switch arm 5200 which is actuated by means of an actuating arm or link 55 pivotally connected to the arm 52a;
this arm or link extending through the casing as at 56 to the outside thereof. (See Fig. 4.) Said arm or link is provided with an ear or extension 51, which is notched at 58 to receive the nozzle arm support 59. The nozzle arm support is preferably constructed of rod material and carries a hook portion 60 at its lower end and an open loop 6| at its upper end. This nozzle arm support is pivotally supported to swing in a horizontal are by bracket 62 secured to the lower part of the casing and by the arm or link 55. The nozzle arm support is also slidable vertically with respect to bracket 62 and arm 55.
Fig. 5 illustrates the position assumed by the nozzle arm support when same is operable to actuate the switch. The loop 6| is swung around clockwise from the inoperative position shown in Fig. 1 and is engaged in notch 58 of the arm extension 51 to lock the nozzle arm support to said arm or link 55. Thus, the nozzle arm In, which comprises the usual rigid hollow wand or handle carrying a nozzle at one end thereof, may be fitted into the support 59 by assembling same in the loops 6| and 60. To operate the switch, the nozzle arm is grasped at its upper end and is laterally moved outwardly away from the casing, the lower end of the arm fulcrumed on the loop 60 and the upper arm portion moves the loop 6| to the dotted position indicated in Fig. 4 to move the switch to on position.
The full line showing in Fig. 4 illustrates the parts with the switch in an off" position. The extension 51 and recess 58 are thus used to lock the rod structure or nozzle arm support 59 in such a manner as to position the loops B and SI so that the handle TI] is quickly and readily inserted in place for actuating the switch. Preferably, when the appliance is not in use, the rod structure 59 is lifted up so that the loop 6| may be swung around and supported on top of the casing as shown in Fig. l. The lower end of the rod 59 is supported by bracket 62, and the hole carried by said bracket is preferably of a larger diameter than the rod so as to permit the nozzle arm support to hinge about the bracket 62 on actuating the switch.
Although I have illustrated but one form of my invention and have described in detail but a single application thereof, it will be apparent to those skilled in the art to which my invention pertains, that various modifications and changes may be made therein without departing from the spirit and scope of my invention or the appended claims.
I claim:
