Abstract
Abstract A sound signaling system is disclosed which includes a vertical frame having a plurality of sound baffles mounted on the frame in vertical alignment, and a plurality of sound transmitters each mounted on one of said baffles to form a vertical array of sound transmitters. Each of the sound transmitters is mounted on its respective baffle by a mounting means which permits the mouth of the sound generator to be adjusted with respect to the baffle from a first position in which the vertical array emits sound signals in a relatively narrow horizontal pattern to a second position in which the array emits such signals in a relatively broader horizontal pattern.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
A directional sound signaling system, comprising, in combination: a vertical frame; at least one sound baffle mounted on said frame in vertical alignment; a plurality of sound transmitters each mounted on at least said one sound baffle to form a vertical array, each of said sound transmitters including a sound driver and a horn acoustically coupled to the sound driver, said horn extending through said baffle and including a mouth opening to emit sound forward of the baffle; and mounting means for so mounting each of said sound transmitters in at least said one baffle to permit adjustment of each of said sound transmitters from a first position with respect to such baffle in which said vertical array emits sound signals in a relatively narrow horizontal pattern to a second such position wherein said array emits such signals in a relatively broader horizontal pattern, said mounting means adapted to mount said horn to permit adjustment of the horn from one of said positions with the opening in said mouth substantially flush with said forward wall of said baffle, to the other of said positions with said opening at a distance forward of said wall.
Claim 2
Dependent Claim
194 words
A directional sound signaling system, comprising, in combination: a vertical frame; at least one sound baffle mounted on said frame in vertical alignment; a plurality of sound transmitters each mounted on at least said one sound baffle to form a vertical array, each of said sound transmitters including a sound driver and a horn acoustically coupled to the sound driver, said horn extending through said baffle and including a mouth opening to emit sound forward of the baffle; and mounting means for so mounting each of said sound transmitters in at least said one baffle to permit adjustment of each of said sound transmitters from a first position with respect to such baffle in which said vertical array emits sound signals in a relatively narrow horizontal pattern to a second such position wherein said array emits such signals in a relatively broader horizontal pattern, said mounting means adapted to mount said horn to permit adjustment of the horn from one of said positions with the opening in said mouth substantially flush with said forward wall of said baffle, to the other of said positions with said opening at a distance forward of said wall.
Claim 3
Dependent Claim
117 words
The sound signaling system of claim 1 wherein said horn is cylindrical and said mounting means is a split clamp encircling said horn and including a semicircular First section mounted on said baffle and a semicircular second section connected to said first semicircular section, and means so connecting said first and second semicircular sections to permit movement of one of said sections with respect to the other for tightly engaging said horn in said clamp to permit said horn to be secured at one of said first or second positions, and for loosely mounting said horn in said clamp to permit movement of said horn through said baffle to the other of said first and second positions.
Claim 4
Dependent Claim
170 words
Sound transmitting apparatus for emitting sound in a plurality of sound patterns comprising, in combination: a baffle including an opening therein and having a forward wall facing the direction in which sound is to be emitted; a sound transmitter including a cylindrical horn portion extending through said opening, said horn portion having a mouth opening to emit sound in said direction, and mounting means for mounting said horn position in said opening to permit adjustment of the position of said mouth opening with respect to said forward wall, said mounting means being a split clamp encircling said horn and including a semicircular first section mounted on said baffle and a semi-circular second section connected to said first semicircular section, and including means so connecting said first and second semicircular sections to permit movement of one of said sections with respect to the other for tightly engaging said horn in said clamp to permit said horn to be secured in said clamp and for loosely mounting said horn in said clamp.
Claim 5
Dependent Claim
170 words
Sound transmitting apparatus for emitting sound in a plurality of sound patterns comprising, in combination: a baffle including an opening therein and having a forward wall facing the direction in which sound is to be emitted; a sound transmitter including a cylindrical horn portion extending through said opening, said horn portion having a mouth opening to emit sound in said direction, and mounting means for mounting said horn position in said opening to permit adjustment of the position of said mouth opening with respect to said forward wall, said mounting means being a split clamp encircling said horn and including a semicircular first section mounted on said baffle and a semi-circular second section connected to said first semicircular section, and including means so connecting said first and second semicircular sections to permit movement of one of said sections with respect to the other for tightly engaging said horn in said clamp to permit said horn to be secured in said clamp and for loosely mounting said horn in said clamp.
