Abstract

Abstract A hand-operated tool is used in removing and replacing grease screens. The tool has an elongated hand gripping portion carrying a spaced element gripping and moving end comprising first means for engaging and moving a screen to a release position to release a margin of the screen from a holding frame and having a second means for supporting a second portion of the screen to maintain the element in a predetermined plane and allow the element to be relocated in a desired area. Grease screens and traps are often located above stoves and fried food cooking areas in restaurants and food service locations of all types. These screens or traps are normally planar elements which act to trap oil and grease particles as air is drawn through them to an exhaust system. The planar elements are often located at various angles to the vertical by conventional moldings which allow sliding of the screens in a plane to release one edge thereof followed by movement of the screen from that plane as by gravity so that the entire screen can be removed from its frame. It is common for restaurant owners to use special screen cleaning services in order to remove screens for cleaning. Servicemen climb ladders to remove screens, replace the screens with clean screens and remove the screens to another premise for cleaning. Weekly service is not uncommon in restaurants of even relatively small volume. Such screen cleaning services exist and are used often because of the difficulties in removing and replacing the screens using ladders and conventional methods of handling.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 123 words
A hand-operated tool for use in removing and replacing grease screen and trap elements positioned at elevated locations in frame means for holding said elements in operative position, said tool comprising, an elongated member having a hand gripping portion and carrying an element gripping and moving end spaced from said hand gripping portion, said gripping and moving end comprising first means for engaging a first portion of said element and moving said element to a release position to release a margin of said element from said frame means, and second means for supporting a second portion of said element by underlying said second portion to maintain said element in a predetermined plane and allow said element to be relocated to a desired area.
Claim 2
Dependent Claim 123 words
A hand-operated tool for use in removing and replacing grease screen and trap elements positioned at elevated locations in frame means for holding said elements in operative position, said tool comprising, an elongated member having a hand gripping portion and carrying an element gripping and moving end spaced from said hand gripping portion, said gripping and moving end comprising first means for engaging a first portion of said element and moving said element to a release position to release a margin of said element from said frame means, and second means for supporting a second portion of said element by underlying said second portion to maintain said element in a predetermined plane and allow said element to be relocated to a desired area.
Claim 3
Dependent Claim 22 words
A hand-operated tool in accordance with claim 1 and further comprising said first means being in the form of upwardly extending prongs.
Claim 4
Dependent Claim 31 words
