,i SWITCH- OPRATIN G MECHANISM.

' Be it known that l, MmroN H. Senna/IAN, ii citizen of the United States, residing at Cleveland, iii the county vof Cuyahoga and State of ()hio,haveI invented a certain new yand useful improvement in Switch-Operating Mechanisnnof which the following is a full, clear, "and exact description, reference being had to the accompanying drawings.

This invention relates particularly to mechanisms for operatin r the controlling switch of electrically driven portable devices. The essential 'object of the invention is to provide a simple, efficient mechanism for operating a switch for such a device. A more specific object is to so arrange such mechanism that the switch may be automatically closed to start the motor when the handle of the device is brought to a position for operating it, and he automaticall opened to stop the motor when the handle is brought to a position of rest.

My switch operating mechanism is adapted Vfor various actcrimenti'one( Acoinmon illustration of such device is an electrically drivenl ortable vacuum cleaner. Such a vacuum cllcianer is ordinarily provided with a handle ,for moving the clean r ahout the surface to be operatednpon, he handle hei'ng .usually pivoted to the frame and adapted to be swung from a vertical to a substantially horizontal position. Devices are provided for latching or otherwise holding the handle' in its vertical position where it may stand when the cleaner is not in use, and when in use thc handle is swung downwardly and operated at angles varying from a. vhorizontal position to approximately seventy or eighty degrees.

Features of my invention are that no attention need be given to the stopping and starting of the motor of the device, for the current is automatically shut oli when the handle is brought to its substantially vertical position, at which the device is normally idle, and as soon as the handle is brought to a slight angle from the vertical, at which the device may be operated, the current is sont through the motor by the first movenient of the handle closing the switch.

The switches for controlling the motors of portable vacuum cleaners, for example, are usually manually operable and are mounted at some point on the handle which requires portabledevices of the char.

l that the `handle carrywires runnin up and'down the same, and, as the Jian es are-usuall provided with a metal cap, there is consi rable danger of the op erator .receiving electric shocks, Awhereas, with my device, the switch may be`mound directly on the motorcasing, and the handle may wiring.

My invention Vis 'hereinafter more fullyy described in' connection with the accompanying drawings showing itsembodiment' in a' portablevacuum cleaner, and the essential characteristics are summarized in the claims. j

In the drawings, Figure` 1 is a side elevation 'of a .suction cleaner equipped with my invention, showing the arts in their idle position; Fig. 2 is a si e elevation of the same illustrating the o Verative position; Fig. 3 is an enlarged si e elevation of the frame of such a cleaner showing the switch and operating device in position; Fig. 4 is a section on a still larger scale showing the means on the handle bail for operatingI the switch, the latter being indicatedin dot and dash lines- Fig. 5 is an edge elevation o'f the operating mechanism and switch Fig. 6 is alsection on the same' plane as 4 looking in the oppositedirection from hat figure, showing the .switch member in dot and dash lines'` Fig. 7 is an axial section throu h the switch and' its operating mem ber; ig. 8 is a detail view showin the switch removed; Fig. 9 is a sectional etail showing the device for latchin the handle in different positions Fig. 10 1s a vertical section of the same; ig. 11 is a horizontal section throu h the handle bail looking down on the atchin device.- y

At 20 is indicated ,the motor housing mounted above the fan cham# ber, and at 22 is shown the dust ba con-v nected with the exhaust-spout and suitably attached at its opposite end to the hau-V los 28 to the sides o' the frame of the cleaner, 110

lHaving thus described my invention. what I claim is:

1. The combination of a pivoted operating handle, an electric switch, said electric` switch comprising a casing, a reciprocating contact member, an actuator outside the casingr for operating said contact member, separated shoulders on the casing. and a projection carried by the actuator for engagingr said shoulders to limit the movement of the actuator, a notch in the periphery of the actuator, an Vupward projection at one side of the notch, and a projection on the handle adapted to engage one side of said notch as the handle is swungr from an uprightto a slantingr position and adapted to engage said upward projection when the handle 1s returned to its upright position, whereby' the actuator may be moved to operate said contact member.

2. The wrnbination of a pivoted operating,r handle, an electric switch, said switch comprisingr a casing, a reciprocating: Contact member, an actuator outside the casing forYV operating said contact member, a notch in the periphery of the actuator. an upward projection at one side of the' notch, and a projection on the handle adapted to engage one side of said notch as the handle is swung .from an upright to an inclined posi-- tion, and adapted to engage said .upward )rojectiou when the handle is returned to its upright position whereby the actuator may be moved to operate said contact member.

3.
