Noise attenuating kit

Claim 2

A noise abatement system for a machine comprising: sound attenuating panel means extending between frame members of said machine enclosing parts of said machine and having open areas between some of said panel means; slidable sound attenuating panel means closing the open areas between fixed panels and extending adjacent to the working area of the machine whereby the slidable panel provides access to the working area, noise protection and object protection to the operator; and said sound attenuating panels means comprises: a flat backing member; and a sound attenuating system coextensive with said backing member and attached to said backing member.

Claim 3

A noise abatement system for a machine as set forth in claim 1 comprising: a skirt made of a resilient material and extending from the bottom of said sound attenuating panels to the floor whereby noise proceeding around the bottom of said panels is attenuated before it proceeds from the area of said machine.

Claim 4

A noise abatement system for a machine as set forth in claim 1 further comprising: at least one passageway through some of said sound attenuating panel means; first angle means having a first flat leg mounted on said broad surface of said sound attenuating panel adjacent each passageway and having a cam surface on the upper surface of the second flat leg of said angle means; second angle means having a first flat leg mounted on said broad surface of said sound attenuating panel adjacent each passageway and on the opposite side of said passageway from said first angle means and having a cam on the upper surface of the second flat leg on said angle means; doors having resilient strip material on one side of each of said doors adjacent the periphery of said doors; and at least two pins projecting from opposed edges of said doors whereby said doors are urged toward said panel when said doors are placed in said panels and said pins engage said cams and urge said doors against said panels.

Claim 5

A noise abatement system for a machine as set forth in claim 1 in which said sound attenuating system comprises: a sound attenuating sheet coextensive with said backing member and having a first and a second flat side; a protective skin means attached to said second flat side of said sound attenuating sheet; and a protective side edge means attached around the side edges of said sound attenuating sheet.

Claim 6

A noise abatement system for a machine as set forth in claim 4 in which said protective side edge means comprises: a flexible protective coating made of a material such as a latex neoprene compound spread thinly over said side edge in the area between said protective skin means and said flat backing member.

Claim 7

A noise abatement system for a machine as set forth in claim 5 in which said protective side edge means comprises: a plastic tape impervious to oil, bonded to said protective skin means, extending To said flat backing member, a latex neoprene coating applied to said tape and said backing member to bond said tape to said backing member;

Claim 8

A noise abatement system for a machine as set forth in claim 1 in which said sound attenuating system comprises: a dense sprayable damping compound adhering to the back of said panel.

Claim 9

A noise abatement system for a machine as set forth in claim 7 in which said sprayable adherent compound comprises: a material such as ''''ANTIPHON D-444''''.

Claim 10

A noise abatement system for a machine as set forth in claim 1 in which said sound attenuating system comprises: a dense sprayable thermal insulating material which is adherent to the back of said panel.

Claim 11

A noise abatement system for a machine as set forth in claim 7 in which said sprayable adherent thermal insulating material comprises: a material such as ''''MONO-THERM''''.

Claim 12

A noise abatement system for a machine as set forth in claim 1 in which said slidable sound absorbing panel means comprises: a panel guide means having a ''''U'''' shaped member attached to said frame members and adapted to cooperate with said slidable panel means to restrict the movement of said panel to a path to open and close the opening in said fixed panel means.

Claim 13

A noise abatement system for a machine as set forth in claim 11 in which said panel guide means further comprises: a ''''Z'''' shaped strip mounted on said guide means; and a felt strip mounted between said ''''Z'''' strip and said slidable panel whereby noise is stopped from leaking between said guide means and said slidable panel.

Claim 14

A noise abatement system for a machine as set forth in claim 1 further comprising: an enclosure mounted on said machine and having five closed sides and one open side for receiving a scrap container; sound proofing material attached to and coextensive with the closed sides of said enclosure; and a passageway in a closed side of said enclosure for receiving a scrap chute whereby the noise from said chute and said scrap container is absorbed by the sound proofing material inside of said enclosure.

Claim 15

A noise abatement system for a machine as set forth in claim 13 further comprising: a lid in the side of said enclosure whereby the scrap bucket may be removed from said enclosure.

Claim 16

A noise abatement system for a machine comprising: sound attenuating panel means extending between frame members of said machine and enclosing operating parts of said machine; openings in said panel means to provide access to the machine inside of said panels means; doors having resilient strip material on one side of each said door adjacent the periphery of said doors; at least two pins projecting from opposed edges of said doors; and paired means each having a cam surface attached to said panel means in opposed positions adjacent each opening in said panel means whereby said pin means cooperates with said cam surface to urge said panel under the influence of gravity to press said resilient strip material against said panel means and form a sound proof seal.

Claim 17

A noise abatement system for a machine comprising: sound attenuating panel means extending between frame members of said machine and enclosing operating parts of said machine; openings in said panel means to provide access to the machine inside of said panels means; doors having resilient strip material on one side of each said door adjacent the periphery of said doors; at least two pins projecting from opposed edges of said doors; and paired means each having a cam surface attached to said panel means in opposed positions adjacent each opening in said panel means whereby said pin means cooperates with said cam surface to urge said panel under the influence of gravity to press said resilient strip material against said panel means and form a sound proof seal.

Claim 18

A noise abatement system for a machine as set forth in claim 15 in which said slidable panel further comprises: a transparent plate means mounted in said panel whereby the working area of said machine may be viewed from outside said machine.

Claim 19

A noise abatement system for a machine as set forth in claim 15 in which said sound attenuating panel means further comprises: a sound attenuating sheet coextensive with said backing member and having a first and a second flat side; means attaching said first flat side to said flat backing member; a protective skin means attached to said second flat side of said sound attenuating sheet; and a protective side edge means attached around the side edges of said sound attenuating sheet.
