Application filed April 5, 1916. Serial No. 89,099. v

This invention relates to a vacuum cleaner of the self-contained type, wherein an electric motor is employed for driving the suction-producingmeans or fan.

The invention has for its general objects -to improve the construction and operation of apparatus of this character so as' to be reliable and eflioient in use, comparatively simple and inexpensive" to manufacture, and so designed that the apparatus will have the maximum range of utility.

A more specific object of the invention is the provision of a vacuum cleaner having a plurality of nozzles or suction heads independently connectible by a valve with suction-producing means, whereby any one device may be used, one of the nozzles being in the form of a handle which, when not used as a nozzle, serves to move the vacuum cleaner over the floor or. surface being cleaned.

A further object of the invention is the provision of a nozzle in the form of a handle which is longitudinally extensible and flexible so as to facilitate the cleaning of walls, windows, door frames, moldings, cornices and other high places.

The invention has as another specific object the provision of a brush in the floor nozzle, whereby the brush will agitate the dust and cause-the same to be drawn into the vacuum cleaner, there being a novel ad'- justing means for the driving connection between the motor and brush, whereby the latter can be thrown out of use when not required.

With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement? of parts which will be set forth with particularity in the following description. and

claims appended hereto. p

In the accompanying drawmgs, which illustrate certain embodiments of the invention and wherein similar characters of reference indicate corresponding parts in all the V Figure l is a central vertical sect1on of a other. ,cleaner is adapted to run on suitably arranged rollers 19. The foregoing describes vacuum cleaner with its parts set for use as in cleaning a floor or rug;

Flg. 2 is a longitudinal section of the combined handle and nozzle partially extended;

Fig. 3 is another View showing the handle fully extended;

Fig. 4: is a detail View of the handle grip; v Fig. 5 is a transverse section on the line 5-5, Fig. 3;

Fig. 6 is a front view of the vacuum cleaner with a portion in section;

Fig. 7 is a transverse section on the line 77, Fig. 1; and i Fig. 8 is a sectional View of a modified form of the invention.

Referring to the drawing, 1 designates the casing or body of the vacuum cleaner, which has an open side 2 to which is applied a dust-holding bag 3, and in the casing l and supported on v a bracket 3 is an electric motor 4:, to the shaft 5 of which is fastened a fan 6, or equivalent suction-producing means. The body 1 has a forward tubular extension or neck 7 which terminates in a transversely enlarged hollow head 8, forming the floor nozzle. The casing 1 has an upwardly extending conduit 9 leading from the inner end of the neck 7 to the top of the casing, and at this point the conduit 9 is hingedly connected and communicates with a tubular handle 10 that also forms a nozzle 1 but is not used while the floor nozzle is employed, since communication with the suction chamber 1* of the casing 1 is controlled by a valve 11 located at the j ncture of the neck 7 andconduit 9 with th chamber 1. The valve is of the rotary type and has a head 12 journaled in an opening 13 in the neck, and a head 14 provided with a threaded journal stud 15 disposed in an opening 16 in the wall of the neck. Between the heads is the gate portion 17 of the valve for controlling communication between the suction chamber and the dust-collecting devices. On the head 12 is a wing 18 adapted to be gripped by the thumb and finger for turning the valve from one position to the The casing or body ofthe vacuum generally the structural features of both forms of the invention shown in Figs. 1 and 8. In Fig. 1 an agitating device is associated with the floor nozzle, whereas in Fig. 8 this-device is omitted. The parts 1 7, 8', 9', ll, 12 and 17 are modifications of the worm 23 is shown raised out of engagement with the worm-wheel 24 sothat the brush would not be rotated by the motor, but when the brush is to be used, the shaft 21 is lowered tdengage the worm with the wormwheel. Toeffect this engagement and disengagement of the worm and worm-wheel the forward end of the shaft 21 is journaled in a bearing 25 slidably mounted on the front wall' 26 of the head 8, the bearing being clamped by a set-screw or equivalent means 27 in any desired position. The shaft 21 is 1 also journaled in a bearing 28 in the neck 7, there, being in the bearing a rubber or other yielding bushing 29 for permitting the shaft 21 to be raised or lowered. The portion 17 of the valve'has a notch 30, so that the shaft will not prevent the valve from being thrown to a position to cut out the floor nozzle.

In order to make use of the handle 10 as a nozzle,'the handle is made'extensible and flexible, and accordingly comprises three telescoping sections 31, 32, 33, the first two of which are flexible, while the latter is stiff or rigid. A hollow hinge bracket 34 is pivotally connected and clamped to the hollow hinge knuckle 36 on the upper end of the conduit 9 by a pivot bolt 37. The outerhandle section 31 is fastened around the hinge bracket or coupling 34. The upper end of the outer section 31 has a fixed stop ring 38, and the intermediate section 32 has at its lower end an external stop ring 39 for preventing the intermediate section 32 from 'being pulled out of'the outer section. In the upper end .of the intermediate section are oppositely disposed stop flanges or lugs '40 which are adapted to be engaged by an external stop ring 41 on the lower end of the inner section 33 when the latter is fully drawn 'out,.as shown in Fig. 3. On the upper end of the inner section 33 are opposltely disposed flanges 42 so disposed that they pass between the stop fianges40 when the intermediate section is drawn out while the inner section is not'in use. The flanges.

- handle grip 43 has clips 44 formed with slots.

45 which are engageable with pins 46 on the upper extremity of the intermediate section 32, as shown iii Figs. 1 and 2. When the inner section 33 is not in use, as shown in of the nut 50 on the bolt 47. A similar clamping bolt 51 is arranged in the handle grip 43 for clamping the handle grip to the upper end of. the inner section when the handle is fully extended, as shown in Fig.3. The bolts 47 and 51 can grip the edges of the section 33 at any point around such edges, so that no special care need be exercised.

From the foregoing description taken in connection with the accdmpanying drawings, the advantages'of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while 1 have described the principle of operation, together with. the device which 1 now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.
