Noise suppression assembly

Claim 2

In a shuttle loom having a lay mounted thereon, front and back box plates mounted on the upper surface of said lay thus forming a box for a shuttle to transverse said lay, and means movably mounted on said loom having one end positioned in communication with said box adjacent the end of said lay to stop the movement of such shuttle across said lay and to propel the shuttle thereacross, the improvement comprising means connected to said loom to suppress the noise caused by contact between such shuttle and said movably mounted means, said noise suppression means comprising a first plate mounted on said lay enclosing said front box plate and said movably mounted means, and a second plate mounted on said loom in a stationary position having its lower edge adjacent the lower edge of said first plate and its upper surface positioned so as to be adjacent the upper surface of the said first plate and enclose the back of said lay when said lay is in its back center position, whereby the end of said lay and said box are enclosed between said first and second plates when the shuttle contacts said movably mounted means but said first and second plates are separated when said lay is in its front center position to permit the release of heat and access to said lay.

Claim 3

The loom of claim 1 wherein said first and second plates of said noise suppression means have a layer of soundproofing material secured to the inner surface thereof.

Claim 4

THe loom of claim 2 in which said soundproofing material is a foamed polyurethane.

Claim 5

The loom of claim 2 in which said soundproofing material has a wire backing secured thereto.

Claim 6

The loom of claim 2 in which said soundproofing material is a laminate of a wire backing secured between layers of said soundproofing material.

Claim 7

The loom of claim 2 in which said soundproofing material is a closed cell foamed plastic.

Claim 8

In a shuttle loom including a lay with front and back box plates mounted on the upper surface thereof thus forming a box therebetween, and a picker assembly including a picker and picker stick movably mounted on said loom having said picker positioned in communication with said box adjacent the end of said lay to propel a shuttle across said lay and to stop movement of a shuttle, the improvement comprising noise suppression means connected to said loom comprising a first plate mounted on said lay enclosing said front box plate and said picker assembly and a second plate mounted on said loom in stationary position, the lower edge of said second plate positioned adjacent the lower edge of said first plate and the upper surface of said second plate positioned so as to be adjacent the upper surface of said first plate and enclose the back of said lay when said lay is in back center position, whereby the end of said lay, said box and said picker are enclosed between said first and second plates when a shuttle contacts said picker, thus suppressing the noise caused by such contact, but said first and second plates are separated when said lay is in its front center position to permit the release of heat and access to said lay, said first and second plates having a laminate of a reinforcing material secured between layers of a foamed plastic secured to the inner surfaces thereof.

Claim 9

In a shuttle loom including a lay with front and back box plates mounted on the upper surface thereof thus forming a box therebetween, and a picker assembly including a picker and picker stick movably mounted on said loom having said picker positioned in communication with said box adjacent the end of said lay to propel a shuttle across said lay and to stop movement of a shuttle, the improvement comprising noise suppression means connected to said loom comprising a first plate mounted on said lay enclosing said front box plate and said picker assembly and a second plate mounted on said loom in stationary position, the lower edge of said second plate positioned adjacent the lower edge of said first plate and the upper surface of said second plate positioned so as to be adjacent the upper surface of said first plate and enclose the back of said lay when said lay is in back center position, whereby the end of said lay, said box and said picker are enclosed between said first and second plates when a shuttle contacts said picker, thus suppressing the noise caused by such contact, but said first and second plates are separated when said lay is in its front center position to permit the release of heat and access to said lay, said first and second plates having a laminate of a reinforcing material secured between layers of a foamed plastic secured to the inner surfaces thereof.

Claim 10

An assembly adapted for use with a shuttle loom to suppress noise caused by contact between a shuttle and the picker comprising first and second plates having a layer of soundproofing material secured to the inner surface thereof, said first plate being adapted to be mounted on the lay of a shuttle loom and said second plate being adapted to be mounted on the loom.

Claim 11

An assembly adapted for use with a shuttle loom to suppress noise caused by contact between a shuttle and the picker comprising first and second plates having a layer of soundproofing material secured to the inner surface thereof, said first plate being adapted to be mounted on the lay of a shuttle loom and said second plate being adapted to be mounted on the loom.

Claim 12

The assembly of claim 8 in which said soundproofing material is a foamed polyurethane.

Claim 13

The assembly of claim 8 in which said soundproofing material has a reinforcing material secured to the surface thereof adjacent the inner surface of said first and second plates.

Claim 14

The assembly of claim 8 in which said soundproofiNg material is a laminate of a wire backing secured between layers of said soundproofing material.

Claim 15

The assembly of claim 11 in which said soundproofing is a closed cell foamed plastic.

Claim 16

An assembly adapted for use with a shuttle loom to suppress the noise created by contact between the shuttle and picker of such loom comprising first and second plates having the inner surfaces thereof of a slightly concaved configuration with soundproofing material secured to said concaved surfaces.

Claim 17

An assembly adapted for use with a shuttle loom to suppress the noise created by contact between the shuttle and picker of such loom comprising first and second plates having the inner surfaces thereof of a slightly concaved configuration with soundproofing material secured to said concaved surfaces.

Claim 18

The assembly of claim 13 in which said soundproofing material is a laminate of a reinforcing material secured between layers of a closed cell foamed polyurethane.

Claim 19

The assembly of claim 14 in which said reinforcing material is a wire backing.

Claim 20

The assembly of claim 8 in which said first and second plates are of semirigid, heat and shock-resistant plastic.

Claim 21
