  • Patent number: 10077791
    Abstract: A shaft coupling device includes a first portion, a second portion, a pair of buttons, a biasing member, and at least one button stop. The first portion has a female couple section and a first device mounting section. The second portion has a male couple section and a second device mounting section. The male couple section is configured so as to be receivable within the cavity of the female couple section. The biasing member, the button stop, and at least a portion of the first and second buttons are disposed within the second cavity of the male couple section, with the biasing member disposed between the buttons, biasing the buttons radially outwardly. The button stop limits the radially inward travel of the buttons.

  • Patent number: 8884770
    Abstract: A cost effective manometer is realized for accurately measuring back pressure in all types of vents and ducts. Common back pressure can be caused by restrictions, such as lint or soot buildup. The manometer consists of a main body having two reservoirs for storage of measuring fluid. The first reservoir contains measuring fluid during transit eliminating the need for end user to manually fill manometer prior to first use. Measuring fluid is transferred to second main reservoir prior to initial use. The second reservoir contains an adjustable bladder or plunger for obtaining a zero reading prior to measurement. The manometer can be used on all types of vents and ducts where positive or negative pressure exists. The manometer can be used for measuring positive or negative pressures as well as differential pressures.

  • Patent number: 8574037
    Abstract: An apparatus adapted to be coupled to a power source having a rotary drive shaft is provided. The apparatus comprises an adapter, an extension pole, and a tool head. The adapter has a drive shaft and a fluid passage. A first end of the adapter drive shaft is adapted to be coupled to the power source drive shaft. The adapter fluid passage is adapted to receive fluid flowing from a source of fluid and to permit flow of fluid there through. The extension pole has a drive shaft and a fluid passage. A first end of the extension pole drive shaft is adapted to be coupled to a second end of the adapter drive shaft. The extension pole fluid passage is adapted to receive fluid flowing from the adapter and to permit flow of fluid there through. The tool head is adapted to be coupled to the extension pole.
