Abstract
Abstract Base of a planar type vibrator is attached to a mounting surface by a tension member extending through the base of the vibrator, controlling it against rotation around the tension member, and holding the base against a curved surface of an interposed elastomeric pad with a controlled degree of compression of the pad.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
Means for attaching to a support member a mechanical vibrator of planar type having at one end thereof two tines adapted to vibrate in a direction normal to the vibrator plane and having at the other end a base portion, said means comprising an elastomeric pad interposed between said base portion and said support member, and a fastener extending from said support member through said pad and through said base portion, said means characterized by one of the adjacent surfaces of said pad and said base portion being cylindrical, with a generatrix of said cylindrical surface extending through said fastener, and said adjacent surfaces being increasingly spaced from each other at increasing distances from said generatrix, said generatrix lying in the same plane as the direction of vibratory movement of the tines of said vibrator when excited in reed mode.
Claim 2
Dependent Claim
140 words
Means for attaching to a support member a mechanical vibrator of planar type having at one end thereof two tines adapted to vibrate in a direction normal to the vibrator plane and having at the other end a base portion, said means comprising an elastomeric pad interposed between said base portion and said support member, and a fastener extending from said support member through said pad and through said base portion, said means characterized by one of the adjacent surfaces of said pad and said base portion being cylindrical, with a generatrix of said cylindrical surface extending through said fastener, and said adjacent surfaces being increasingly spaced from each other at increasing distances from said generatrix, said generatrix lying in the same plane as the direction of vibratory movement of the tines of said vibrator when excited in reed mode.
Claim 3
Dependent Claim
40 words
The attaching means of claim 1, wherein said cylindrical surface is of circular section, and said fastening means compresses said pad in an amount in the range of 2.5 to 5 per cent of the radius of said circular section.
Claim 4
Dependent Claim
22 words
The attaching means of claim 2, wherein said pad has a thickness of approximately one-third of the radius of said circular section.
Claim 5
Dependent Claim
24 words
The attaching means of claim 1, wherein said pad is of neoprene rubber with a hardness in the range of 30 to 50 durometer.
Claim 6
Dependent Claim
156 words
Means for attaching a mechanical vibrator to a support member, where said mechanical vibrator is of the type having at one end thereof two tines lying in a common plane at rest and vibrating in a direction normal to said plane, and having a base portion at the other end thereof, said means comprising an elastomeric pad interposed between said base portion and said support member, and fastening means extending from said support member through said pad and said base portion and holding said base portion in compression against said pad, characterized by the adjacent surfaces of said pad and said base portion being one flat and the other curved, Said curved surface being cylindrical, with a generatrix of said cylindrical surface extending through said fastening means, and said cylindrical surface being so oriented that said generatrix lies in a common plane with the direction of vibratory movement when said vibrator is excited in reed mode.
Claim 7
Dependent Claim
156 words
Means for attaching a mechanical vibrator to a support member, where said mechanical vibrator is of the type having at one end thereof two tines lying in a common plane at rest and vibrating in a direction normal to said plane, and having a base portion at the other end thereof, said means comprising an elastomeric pad interposed between said base portion and said support member, and fastening means extending from said support member through said pad and said base portion and holding said base portion in compression against said pad, characterized by the adjacent surfaces of said pad and said base portion being one flat and the other curved, Said curved surface being cylindrical, with a generatrix of said cylindrical surface extending through said fastening means, and said cylindrical surface being so oriented that said generatrix lies in a common plane with the direction of vibratory movement when said vibrator is excited in reed mode.
Claim 8
Dependent Claim
44 words
The attaching means of claim 5, wherein said fastening means is of non-circular cross-section, and passes through holes of matching non-circular shape in said pad and said vibrator, whereby the relative orientation of said pad and said vibrator around said fastening means is maintained.
Claim 9
Dependent Claim
191 words
Means for attaching a mechanical vibrator to a support member, where said mechanical vibrator is of a type having vibrating tines at one end thereof and a flat base portion at the other end thereof, said means comprising an elastomeric pad having a length dimension and having a thickness varying from a minimum at one end of the length thereof, to a maximum at a mid point thereof, and to a minimum again at the opposite end thereof, but of uniform thickness across any section taken transversely to the length thereof, said pad being interposed between said base portion and said support member, and a fastening means extending from said support member through said pad at its maximum thickness, and through said base portion, maintaining said base portion and said pad in pressure contact and adapted to prevent relative rotation of said vibrator around said fastening means with respect to said pad, whereby said pad and said base portion are maintained in relative orientation such that the direction of movement of the tines of said vibrator in reed mode is parallel to a plane transverse to the length of said pad.
Claim 10
Dependent Claim
191 words
Means for attaching a mechanical vibrator to a support member, where said mechanical vibrator is of a type having vibrating tines at one end thereof and a flat base portion at the other end thereof, said means comprising an elastomeric pad having a length dimension and having a thickness varying from a minimum at one end of the length thereof, to a maximum at a mid point thereof, and to a minimum again at the opposite end thereof, but of uniform thickness across any section taken transversely to the length thereof, said pad being interposed between said base portion and said support member, and a fastening means extending from said support member through said pad at its maximum thickness, and through said base portion, maintaining said base portion and said pad in pressure contact and adapted to prevent relative rotation of said vibrator around said fastening means with respect to said pad, whereby said pad and said base portion are maintained in relative orientation such that the direction of movement of the tines of said vibrator in reed mode is parallel to a plane transverse to the length of said pad.
Claim 11
Dependent Claim
44 words
The attaching means of claim 7, wherein said fastening means is of non-circular cross-section, and passes through holes of matching non-circular shape in said pad and said vibrator, whereby the relative orientation of said pad and said vibrator around said fastening means is maintained.
