Suction cleaner

Claim 2

In a suction cleaner, a combined suction cleaner cover and diaphragm, said combined suction cleaner cover and diaphragm formed from a resilient material, a motor cut off switch in said combined suction clean cover and diaphragm, an operating plunger connected to said motor cut off switch, a support bar mounted beneath the combined suction cleaner cover and diaphragm, in cooperative relationship with said operating plunger, whereby flexture of said combined suction cleaner cover and diaphragm causes said operating plunger to move against said support bar with enough force to actuate the motor cut off switch.

Claim 3

The apparatus described in claim 1 wherein said operating plunger is positioned so it abuts the support bar at all times.

Claim 4

The apparatus described in claim 1 wherein a motor is mounted in said combined suction cleaner cover and diaphragm, said motor cut off switch electrically connected to the motor to cut off power to said motor when the switch is actuated.

Claim 5

In a suction cleaner, a combined suction cleaner cover and diaphragm, said combined suction cleaner cover and diaphragm dome shaped and formed from a resilient material, a motor cut off switch mounted in the combined suction cleaner cover and diaphram, an operating plunger connected to said motor cut off switch and extending through said combined suction cleaner cover and diaphragm, a support bar secured to spaced portions of the combined suction cleaner cover and diaphram at its opposed ends, said operating plunger in abutting relation to the support bar, whereby flexture of said combined suction cleaner cover and diaphram causes said operating plunger to move against said support bar with enough force to actuate the motor cut off switch.

Claim 6

In a suction cleaner, a combined suction cleaner cover and diaphragm, said combined suction cleaner cover and diaphragm dome shaped and formed from a resilient material, a motor cut off switch mounted in the combined suction cleaner cover and diaphram, an operating plunger connected to said motor cut off switch and extending through said combined suction cleaner cover and diaphragm, a support bar secured to spaced portions of the combined suction cleaner cover and diaphram at its opposed ends, said operating plunger in abutting relation to the support bar, whereby flexture of said combined suction cleaner cover and diaphram causes said operating plunger to move against said support bar with enough force to actuate the motor cut off switch.

Claim 7

The apparatus described in claim 4 wherein a motor is mounted in said combined suction cleaner and diaphragm, said motor cut off switch electrically connected to the motor to cut off power to said motor when the switch is actuated.

Claim 8

A suction cleaner of the class described comprising a combined suction cleaner cover and diaphragm and a container can, an electric motor mounted in the combined suction cleaner cover and diaphragm, said container can having a suction inlet, said Electric motor connected to fan means for creating a flow of air through said container can, a fliter mounted in the container can between said combined suction chamber cover and diaphragm and the suction inlet, said combined suction cleaner cover and diaphragm generally dome shaped and formed from a resilient material, a support bar secured to spaced portions of said combined suction cleaner cover and diaphragm at its opposed ends, a motor cut off switch mounted in said combined suction cleaner cover and diaphragm and electrically connected to the motor to cut off power to the motor when the switch is actuated, an operating plunger connected to said motor cut off switch and extending through said combined suction cleaner cover and diaphragm into abutting relationship with the support bar, whereby if the filter becomes clogged while the motor is operating, the decreased flow of air through the container can cause a decrease of pressure inside the can relative to the external pressure whereby the external pressure forces said combined suction cleaner cover and diaphragm to flex inwardly causing said operating plunger to move against the support bar with enough force to actuate the motor cut off switch and stop the motor.

Claim 9

A suction cleaner of the class described comprising a combined suction cleaner cover and diaphragm and a container can, an electric motor mounted in the combined suction cleaner cover and diaphragm, said container can having a suction inlet, said Electric motor connected to fan means for creating a flow of air through said container can, a fliter mounted in the container can between said combined suction chamber cover and diaphragm and the suction inlet, said combined suction cleaner cover and diaphragm generally dome shaped and formed from a resilient material, a support bar secured to spaced portions of said combined suction cleaner cover and diaphragm at its opposed ends, a motor cut off switch mounted in said combined suction cleaner cover and diaphragm and electrically connected to the motor to cut off power to the motor when the switch is actuated, an operating plunger connected to said motor cut off switch and extending through said combined suction cleaner cover and diaphragm into abutting relationship with the support bar, whereby if the filter becomes clogged while the motor is operating, the decreased flow of air through the container can cause a decrease of pressure inside the can relative to the external pressure whereby the external pressure forces said combined suction cleaner cover and diaphragm to flex inwardly causing said operating plunger to move against the support bar with enough force to actuate the motor cut off switch and stop the motor.
