Abstract
Abstract In a bracket for holding a transducer of the type useful for emitting sonar waves for detecting underwater terrain or fish, the bracket includes a first expansion clamp, and a fastening member generally disposed oppositely from said first expansion clamp, and a spacer designed for rigidly holding these two components a fixed distance from each other. The first expansion clamp may be secured to a support, such as the shaft of a trolling motor, while the fastening member is designed for holding the transducer. The fastening member may comprise either a second expansion clamp, having approximately three pairs of vertically aligned expansion grips, or it may include an angulated plate member, the upright portion of which is secured to the spacers, while a permanent form of transducer may be mounted through an aperture provided in the bottom portion of the plate member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
220 words
In a bracket for holding a transducer to the shaft for a trolling motor or other support and which is useful for detecting underwater objects such as terrain and location of fish, said bracket including at least one clamp means for securing said bracket to a support, said clamp means comprising a first expansion clamp for removably securing said bracket to a support, said expansion clamp including at least two pairs of integral expansion grips vertically aligned, at least one fastening member extending substantially oppositely away from said first expansion clamp and designed for securing a transducer, said fastening member comprising a second expansion clamp, said second expansion clamp including a base member, a series of pairs of arcuately shaped expansion grips integrally extending from said base member, at least one spacer means arranged fixed intermediate each expansion grip of the first expansion clamp and the base member of the second clamp and providing clearance for a secured transducer away from its support, each spacer comprising a length of sleeve, a fastener arranged through each sleeve for holding to its ends the grips of the first expansion clamp and the base member of the second clamp, and each said fastener being seated within the base member to provide clearance for support of a transducer by its series of expansion grips.
