ELECTRIC SUCTION CLEANER Filed Aug. 15, 1929 2 Sheets-Sheet 2 W147644= 1? James M/Vaul Patented June 24, 1930 V UNITED STATES PATENT ZOFFICE JAME$ M. NAUL, OF PLAINFIELD, NEW JERSEY, ASSIGNOR TO THE SINGER MANU- FACTURING COMPANY, OF ELIZABETH,
JERSEY NEW JERSEY, A CORPORATION OF NEW ELECTRIC SUCTION CLEANER Application filedAugust 15,
This invention relates to vacuum or suction cleaners of the portable electr1c motordrlven type having a motor, a fan, a cleaning nozzle and a dirt-receptacle, which are being desirable to run the vacuum cleaner at a speed such that the particular rug being cleaned will not stick to the cleaner nozzle and thus be dragged over the floor.
A further object of the invention is to provide for the speed-control of a suction cleaner without encumberi-ng the outfit with unsightly enlargements, protuberancesor heatgenerating devices.
Still further, the invention has for an object to provide a speed-controlled suction cleaner which is easy to operate and in which the starting and stopping means and the speed-controlling means are closely associated for convenience of operation, but are separated in such a way as to be unlikely to confuse the operator.
To the attainment of the ends in view,
the motor of the device, which is preferably of the series commutator type, is provided with a tapped field-winding, the taps of which are extended into the hollow handle of the device, together withthe main motor leads One leg of the current-supply cord is connected through a single-pole singlethrow on-and-off switch to'one of the motor leads. The motor-field taps are connected to the points of a selector-switch, the movable contact element of which is connected to the other leg of the current-supply cord. The on-and-off switch is preferably mounted upon a plate provided with an inlet aperture and spring guard for "the current-supply cord; such plate being mounted at the under side of the vacuum cleaner handle near the upper or free end of the latter; the pivoted 1929. Serial No. 386,165.
handle of the switch projecting outwardly from thehandle alongside the current-supply cord and hence readily associated with the cord in the mind of the operator as the switch-handle for turning the electric current on or off. The selector-switch is preferably mounted on a separate plate secured to the vacuum cleaner handle near the free end of the latter but on the upper or opposite side of the handle from the on-andofi' swltch. The selector or speed-control switch is thus readily accessible for convenient operation, yet is so separated from the onand-off switch as to be naturally readily distinguished from the latter.
In the accompanying drawings, Fig. 1 is a side elevation of a suction cleaner embodythe wiring of the device. Fig. 3 is a longitudinal vertical section through the handle of the device. Fig. 4 is a longitudinal section through the lower end of the handle, showing the plug-connection between the motor leads and the conductors within the handle. Fig. 5 is a perspective view of the female member of the connector. Fig. 6 is a perspective view of the male member of the connector. Fig. 7 is anencl view of the connector-member shown in Fig. 5 Fig. 8 is a bottom plan view of the selectorswitchshown at the left in'Fig. 3, and Fig. 9 is a top-plan view of the on-and-off switch shown at the right in Fig. 3.
In the preferred embodiment of the invention illustrated, 1 represents'the fan-casing or body of a suction cleaner having a cleaning nozzle 2 and carrying an electric motor 3 direct connected as usual to a fan 3' within the casing 1. The usual dirt-receptacle 4 hangs from the hook 5 on the switchplate 6 and is connected to the air-discharge tube 7 leading from the casing 1.
The motor is preferably of the series commutator type having an armature M and field f connected in series with the main motor leads 8, 9. The field winding f is tapped between its ends and the tap 10 is included with the leads 8 and 9 in the cable 11 which extends from the motor 3 to a male member 12 of a threepin plug-connector ing the invention. Fig. 2 is a diagram of which is received by the mating member 13 fitted into and closing the lower end of the hollow tube 14 constituting the handle of the suction cleaner.
Screwed to the under side of the-handle 14 over the slot 15 near the upper end of the handle is the switch plate 6 previously referred to. This plate is formed with an inlet aperture 16 for the current-supply cord 17 which is protected by the usual spring wire guard 18. Screwed to the switch-plate 6 and disposed within the slot 15 in the handle-tube 14 is a singleole single-throw toggle-switch 19 of stan ard construction. The switch shown has a pivoted operating handle 20 and a movable bridging contact member 21 which in its on position connects the stationary contact 22 to a similar contact 22 at the other side of the switch, thereby connecting one leg of the current-supply cord to the main motor-lead 8. Secured over the slot 23 in the upper side of the handle is a switch-plate 2-1 on which is mounted a standard sin lepole double-throw toggle-switch 25 serving as a selector-switch to connect the other leg of the current-supply cord 17 to one or the other of the field connections 9, 10.
The switch 25 comprises a. pivoted switchlever 26, a bridging contact member 27, a pair of contacts 28, 29 on one side of the switch, and a pair of similar contacts 28', 29' similarly disposed at the other side of the switch, all supported in insulate-l relation. One current-supply wire 17 is con.-
nected to the two under side contacts 28,
29. The field terminal lead 9 is connected to the contact 28, and the field-tap 10 is connected to the contact 29. lVith the switch-lever in the up position shown in Fig. 3,'the current supply wire 17 is connected to the field-tap 10 and the motor will run at its higher speed. When the switch-lever 26 is thrown down to the position shown in Fig. 1, the motor will run at its lower speed. Manipulation of the switch-lever 20 will start and stop the motorregardless of the setting of the speed-control switch-lever 26.
Both switch- levers 20, 26 are simultaneously accessible to one of the operators hands and, being on different sides ofthe handle 14, are easily distinguished from one another. The operatorlearns naturally that the on-and-oif switch is the one closely associated with the current-supply cord.
The motor is preferably so wound and its brushes so set as to have universal characteristics, that is, to run at substantially the same speeds on either direct or alternating current of a given voltage.
Having thus set forth the nature of the invention, what I claim herein is:
1. In a suction cleaner, the combination with a fan-casing and nozzle, of an elecand a plurality of speed-control leads, a 1101- low tubular handle connected to said fancasing and through which said leads extend, a-plurality of separate switches disposed within said handle and having operating means exteriorly disposed at different'sides of said handle, and a current-supply cord leading into said handle, one of said switches being an on-and-ofi' switch connected in one of the current-supply legs and the other switch being a selector-switch connected to the speed-control leads from the motor.
. 3. A suction cleaner having an electric. motor with a plurality of speed-control leads, a hollow handle for propelling said cleaner, said handle having slots in its upper and under sides adjacent its free end, a switch-plate covering the under slot in said handle and formed with an inlet aperture for the current-supply cord, an on-andofi' switch connected to said motor and mounted on said switch-plate and disposed in said under slot, a second switch-plate covering the upper slot in said, handle, and a selectorswitch mounted on said second switch-plate and disposed in said upper slot and connected to the motor speed-control leads.
4. A suction cleaner having a casing including a cleaner nozzle, an electric motor mounted on said casing and having a tapped field winding, a handle for propelling the cleaner casing and nozzle, :1 switch mounted on said handle and connected to said tapped field winding to vary the ef-' JAMES M.
