DANIEL B. BEPLOGLE, OF BERKELEY, CALIFORNIA.

VACUUM-CLEANER.

To all whom it may concern:

Be itknown that I, DANIEL B. Rnrroonn, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Vacuum- Cleaners, of which the following is a specification.

The present invention relates to electrically operated manually portable vacuum cleaners. The objects of the invention are to provide hollow air carrying handles for such cleaners, to combine electrical conductors and connections through the walls of said handles, and to improve the means of connecting said handles to the vacuum producing means and dust collecting systems now in use.

To these ends, the invention consists of the construction, arrangement and combinations of parts as herein described and illustrated in the accompanying drawings in which,

Figure 1 is a side view of a cleaner embodying the essential features of my invention. Fig. 2 is a partial front view. Fig. 3 is an enlarged detail cross section on line m--a2 of Fig. 1. Fig. 4 shows extension tube and cleaning connections slidable within the main tube of the device. Fig. 5 shows detail view of air control. Fig. 6 shows detail of deflector used in air control.

Fig. 7 shows a substitute form of the cleaner adapted to blow the dust collected through the hollow handle. Fig. 8 is an underside view of the floor tool and its con nections, in the substitute form. Fig. 9 shows a link used to connect floor tool shown in Fig. 8. Fig. 10 is a rear view of the roller supports used in the substitute form. Fig. 11 shows method of connecting the substitute form of the cleaner to base board hose ipe and electrical connections.

Re erring to the several figures, the main tube 1 connects to the common form of electrically operated cleaner having a motor 2 driving a fan within the fan case 3. The tube 1 may serve either as suction or blowing pipe, and when used for suction it may have a flexible tube 4 and a hinge ring member 5 for connection purposes. The ring 5 is hinged to a lug 6 by means of a bolt and nut 7. The tube communicates with the port of the fan case and tool or nozzle 10 through the suction chamber 8 and is held in position by means of the clamp ring!) Specification of Letters Patent.

fitting to the nipple 9'. The nozzle 10 may have roller supports 11, 11. The

rollers

12, 12 support the main weight of the whole device. Similarly the flexible tube 15 is slid within the tube 15 through the nipple 17 and extending to 17 or beyond, so that the three parts of the handle are all telescoped together, when not in use. The main tube 1 may also be connected to the

exhaust

13 or 13 when it is desired to use it as a blowing pipe. A. clamp 14 is designed to contract the upper end of the main tube 1 and the extension tube 15 having a plain lower end 16 and a tool attachment nipple 17 at its upper end is slidable within the main tube, but may be secured from sliding by tightening the clamp 14. A flexible tube 15' operably connecting with a cleaning tool 15" illustrates a use of this tube 15, which may be slid within until its lower end reaches the point 16' when shipping or carrying the device about. A control valve or deflector 18 swinging on the shaft 19 and turnable by the wing knob 19' is operably connected within the suction chamber 8.

The walls of the main tube 1 are of electrical insulation material. From any source 20 an electrical cord 21 carries current to the connector 21 connecting with the strips of copper or other good conducting metal, embedded or secured in the walls of the tube, being thus insulated from each other and from without and within the tube 1. The wires of the conduction cord are designed to suitably connect to the

terminals

24 and 25 which are in turn suitably soldered or connected to the

strips

22 and 23 in the wall of the tube 1. These strips or flat wires are preferably wrapped in between the layers of adhesive paper or fiber during the making of the tube and are bared by rasping off or cutting when soldering to them is required.

In the substitute form shown in Fig. 7 a conduit 3' closable with a cap 3" and fitted with a flexible hose 4' takes the place of suction chamber 8 in the other form, and the nipple 3* connects to the tube 1 by means of a ring clamp 3" and braces 12 having keepers 12" connect the roller support 2 with the floor tool 10. In this form the fan case 3 is a modified form of the case 3 by having the exhaust 13 extended in length and brought to substantially a perpendicular to the plane of the fan case and threaded,

so as to be adapted to securing the handle 1.

In this form also the section of flexible hose 4' serves as a flexible joint, operably connecting the floor tool 10 to the suction chamber 8 leading into the port of the fan case. This joint is in close proximity to the axes of the roller supports 12, 12 whereby free swinging of the handle 1 is permitted Without strain on said flexible hose.

In operation of the form shown in Fig. 1 the air current or suction is through the floor tool or handle according as the deflector is set to the full or dotted line position in Fig. 5. When it is desired to deliver dust through the handle, instead of using same for suction, the handle 1 is to be connected either directly, or indirectly by means of the short hose, to the

nipple

13 or 13 and the, outer end of the handle communicates with any hose pipe leading out of the room as suggested in Fig. 11.

Having thus described the invention it is evident that many variations of detail may be adopted without departing from the intent of the claims which are:

1. A vacuum cleaner comprising, portable electric motor driven vacuum producing means, a suction tool arranged to cotiperate therewith for gathering dust, a main tube having walls of insulating material, electric conductors leading to the motor driven matinee means, embedded in the said walls, the said main tube being operably connected and adapted to serve as a handle to the device, to carry dust laden air. and also to serve as an insulator of the said conductors.

2. In a vacuum cleaner, vacuum producing means, a suction tool, a conduit operably connecting said suction tool to the vacuum producing means, roller supports carrying said vacuum producing means, a portion of the conduit aforesaid being a flexible hose in the vicinity of the axes of said roller supports; together with a handle secured to, and carrying the said parts.

3. In combination, portable electric driven vacuum producing means, a suction tool, a conduit operably connecting said suction tool to the vacuum producing means and adapted to lead air thereinto; and a rigid tubular conduit, suitable as a handle, operably connected to said vacuum producing means and arranged to simultaneously lead air therefrom.

In testimony whereof I aflix my signature in presence of two witnesses.
