PARDEE, OF L a D, OEIQ, ASSIGNOR T0 THE SCOTT AND FETZER COM- PANY, 0F GLEVELAND, OHIO, A CORPORATION OF OHIO ELECTRIC SUCTION CLEANER Application filed February 16, 1929. Serial No. 340,480.

This invention relates to electric suction cleaners and has for its object the provision of an improved electrical connection. and switch adapted to facilitate the removal and replacement of the electric cord and/or hanlfile and the actuation of the switch by the oot.

Fig. 1 is a side elevation of a specimen cleaner embodying my improvements; Fig.

1c 2 is a perspective view of the electrical switch and connection, showing the parts separated; and Fig. 3 is a sectional View of the switch and connector.

The cleaner herein shown is of the well 1.; known horizontal type comprising a collecting nozzle 1, fan casing 2 and motor housing 3, rigidly secured together in the order named from front to rear the nozzle having an inlet mouth a and the casing having wheels 5, 5 by which it is supported with said mouth in operative relation to the supporting surface. Communicating with'one side of the fan casing is the outlet neck 6 to which is secured a dust bag (not shown);

2:] and pivoted to the casing as by the lugs 7 is ahandle yoke 8 to which is secured a handle 9 by which the cleaner is manipulated. 0rdinarily the electric current is conveyed to the motor (not shown) enclosed within the housing 3, by means of a flexible conductor 10 sometimes fastened to the handle; and it is sometimes convenient to disconnect the cord from the casing, either to enable the removal of the handle from the cleaner when 3.; the cord is attached to said handle as it sometimes is, or for other reasons.

To accomplish this, and also to facilitate the operation of the controlling switch, l have provided the fittin shown in Figs. 1

4 and 2 which comprises a ollow, metal housing 12 formed at one side with flanges 13 by which it is screwed to the hou'smg, and formed at its opposite side with a .slot 14:, through which projects a lever 15, adapted to be actuated by the users foot.

ing is formed at one endfnamely the end presented toward the rear of the cleaner with a hollow extension 16, forming a shield for the fingers 17 of a separable electric connection. The other member of said connec- Said castion comprises a plug 18, generally made of insulating material carried by the end of the conductor 10, and having sockets 19 therein for the reception of the fingers 17, and contact members in said sockets suitably connected to conductors in the chord 10. Suitable switch mechanism (not shown) located inside the housing 12 serves to make and break the circuit between the fingers 17 and v the motor depending upon the position of the lever 15.

I do not consider it necessary to illustrate this switch mechanism, or to describe it at any length, since the same is not my invention, but several constructions susceptible of being used herein are known, and are in sale inthe market, and available and known to those skilled in the art.

Having thus described my invention what I claim is:

l. A combined switch and separable connector for electrip vacuum cleaners comprising a hollow housing having at one side an attaching flange, at the opposite side an opening, and between them a hollow projecting neck having parallel walls, switch mechanism inside said housing and having-a pair of terminals projecting into said neck and parallel thereto; a plug fitting removably in said neck and having contact members cooperating with said terminals, and an operating member for said switch projecting through said opening and positioned to be moved by the operators foot.

2. An electric floor cleaning device comprising a casing movably' supported close to the floor, said casing having a switch casing formed with a vertical slot, a lever projecting from said slot and movable up and down therein, and switch mechanism connected to said lever to be operated thereby, said lever being positioned close to the floor and at one side of the device where it can be reachedby the operators foot and the entire upper face of said lever having a downward slope.

3. An electric floor cleaning device comprising a casing having a fan chamber and a motor housing arranged in the order named from front to rear, the motor housing having a substantially cylindrical external part, and 1 wheels whereby said casing is supported with said housing substantially horizontal and near the floor, of a vertically movable controlling lever projecting outwardly and downwardly from said housing at one side and, the upper face of said lever having an outward and downward slope in at least its depressed position.

4:. An electric floor cleaner comprising a famchamber and a motor housing secured together andwheels supporting said casing with said motor housing substantially horizontal and at the rear of the fan-chamber, and a combined switch and connector carried by said housing and comprising a hollow casing secured to said housing in the rear of said fan-chamber, said casing having a vertical slot in its side which is opposite said housing and an opening in a side which is adjacent to said housing, a separable connector having part inside said casing and a companion part removably received in said opening, and a switch in said casing having an operating lever projecting outwardly and downwardly through said slot.

In testimony whereof I hereunto afix my signature.

LLOYD W. PARDEE.
