Abstract
Abstract A sound suppression hood assembly for use in reducing ambient noise levels generated by high intensity machinery, such as vibratory finishing machines or the like. The assembly includes a sound absorbing hood adapted to cover at least the upper portion of the sound-generating machine, and means for supporting the hood in pivotable relationship with respect to the machine. The support means is thus adapted for pivoting the hood about a horizontal axis, from a first, substantially horizontal position at which the hood overlies the covered machine portion, to a second or open position, at which the hood is displaced to a more vertical orientation, so as to enable access to the machine by an operator thereof.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
213 words
A sound suppression hood assembly for use in reducing ambient noise levels in the presence of high sound intensity machinery, comprising in combination: a sound-absorbing hood adapted to cover at Least the upper portion of a floor-supported high sound intensity machine; stand means including an upright and means supporting said upright with respect to said floor, for pivotably supporting said hood with respect to said machine; a pivot assembly being secured between one side of said hood and said stand means; and force biasing means being provided at said stand means and pivot assembly, for counterbalancing said hood weight to facilitate pivoting of said hood back and forth between a first substantially horizontal position at which said hood overlies but is in spaced relationship to said covered machine portion, and a second, open position at which said hood is displaced to a more vertical orientation, to enable access to said machine by an operator thereof, said upright and said support means for said upright both being positionable to one side of said machine whereby access to said machine is substantially unimpaired when said hood is in said open position, and said stand means being spaceable substantially in its entirety from said machine, whereby direct coupling of machine vibrations to said hood is minimized.

Dependent Claim
213 words
A sound suppression hood assembly for use in reducing ambient noise levels in the presence of high sound intensity machinery, comprising in combination: a sound-absorbing hood adapted to cover at Least the upper portion of a floor-supported high sound intensity machine; stand means including an upright and means supporting said upright with respect to said floor, for pivotably supporting said hood with respect to said machine; a pivot assembly being secured between one side of said hood and said stand means; and force biasing means being provided at said stand means and pivot assembly, for counterbalancing said hood weight to facilitate pivoting of said hood back and forth between a first substantially horizontal position at which said hood overlies but is in spaced relationship to said covered machine portion, and a second, open position at which said hood is displaced to a more vertical orientation, to enable access to said machine by an operator thereof, said upright and said support means for said upright both being positionable to one side of said machine whereby access to said machine is substantially unimpaired when said hood is in said open position, and said stand means being spaceable substantially in its entirety from said machine, whereby direct coupling of machine vibrations to said hood is minimized.
Claim 3
Dependent Claim
18 words
Apparatus in accordance with claim 1, wherein said hood comprises opposed thin skins and an intervening sound-absorbing core.
Claim 4
Dependent Claim
26 words
Apparatus in accordance with claim 1, wherein said biasing means comprises a rod, piston and cylinder assembly, extending between said stand means and said pivot assembly.
Claim 5
Dependent Claim
14 words
Apparatus in accordance with claim 5, wherein said piston is biased by a spring.
Claim 6
Dependent Claim
37 words
Apparatus in accordance with claim 1, further including handle means secured to said cover and projecting externally therefrom, for grasping by said operator, whereby to enable operator-activated movement of said cover between said first and second positions.
Claim 7
Dependent Claim
24 words
Apparatus in accordance with claim 1, wherein said hood is of generally bowl-shaped configuration, and comprises opposed plastic skins and an intervening noise-absorbing core.
Claim 8
Dependent Claim
139 words
In combination with a floor-supported vibratory finishing machine of the type including a treatment chamber and chamber access means at the top of said machine; a sound suppression hood assembly, comprising in combination: a sound absorbing hood configured to surround at least the upper portion of said vibratory finishing machine including the said chamber access means; and means for supporting said hood in pivotable relationship with respect to the upper portion of said machine, said means being adapted for pivoting said hood about a horizontal axis from a substantially horizontal position at which said hood overlies but is in spaced relationship to the upper portion of said finishing machine, to a second, open position at which said hood is displaced to a more vertical position, to enable an operator to utilize the said access means for said treatment chamber.
Claim 9
Dependent Claim
139 words
In combination with a floor-supported vibratory finishing machine of the type including a treatment chamber and chamber access means at the top of said machine; a sound suppression hood assembly, comprising in combination: a sound absorbing hood configured to surround at least the upper portion of said vibratory finishing machine including the said chamber access means; and means for supporting said hood in pivotable relationship with respect to the upper portion of said machine, said means being adapted for pivoting said hood about a horizontal axis from a substantially horizontal position at which said hood overlies but is in spaced relationship to the upper portion of said finishing machine, to a second, open position at which said hood is displaced to a more vertical position, to enable an operator to utilize the said access means for said treatment chamber.
Claim 10
Dependent Claim
45 words
Apparatus in accordance with claim 7, wherein said support means comprises a stand engaging the underlying floor at one side of said finishing machine; and a pivot assembly secured to one side of said hood and to an axis of rotation at said pivot assembly.
Claim 11
Dependent Claim
29 words
Apparatus in accordance with claim 8, further including force biasing means at said stand and pivot assembly, for facilitating displacement of said hood between said first and second positions.
Claim 12
Dependent Claim
27 words
