Abstract
Tongs have two arms pivoted together. A finger extends at an angle from one end of each arm. The tongs are used to remove a filter from a hood above a grill. A frame on the filter in the hood is engaged by the tips of the fingers when the fingers are extended. Then the filter with the frame is pulled from the hood.
Claims16
A tool for removing and replacing a filter from a filter hood comprising:
- a) an elongated handle arm having
- i. a distal end,
- ii. a proximal end, and
- iii. a pivot point between the distal end and proximal end,
- b) an elongated stud arm having
- i. a distal end,
- ii. a proximal end, and
- iii. a pivot point between the distal end and the proximal end,
- c) the arms pivoted together at the pivot point of each arm by a pivot pin having a pin axis,
- d) an elongated handle arm finger extending at an angle to the handle arm having one end connected to the distal end of the handle arm, and a handle filter tip at the other end of the finger, and
- e) an elongated stud arm finger extending away from the handle arm finger and extending at an angle to the stud arm having one end connected to the distal end of the stud arm and a stud filter tip at the other end of the stud arm finger, and
- f) the arms and fingers all extending close to a plane normal to the pivot pin axis, so arranged and constructed that when the arms are closed to the aligned position then the fingers are extended a maximum distance apart.

- g) a stop means on the tool for stopping the rotation of the arms in one direction when the arms are aligned and the filter tips are extended a maximum distance apart and said stop means also for permitting the rotation of the arms from alignment in a direction which retracts the filter tips toward each other,
- h) a stud on the stud arm,
- j) a notch having a bight in the handle arm,
- k) said stud in the notch and contacting the bight when the arms are aligned and the filter tips are extended.
