Abstract
Abstract A vibrating reed selector is disclosed in which a unitary motorcontact unit is encapsulated in a protective housing. The motorcontact unit contains a contact assembly, a motor assembly and an end magnet all of which are joined in a rigid structure. The contact assembly includes a ceramic circuit board rigidly attached to the end magnet at one end, two vibrating tines which carry two moving contacts and two contact brackets which carry two fixed contacts. The motor assembly includes a coil wound bobbin and a core which extends through the bobbin and which is rigidly attached to the end magnet at one end and the circuit board at the other.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
A vibrating reed device including a support, two tines mounted on said support and arranged to vibrate when stimulated by a pulsing magnetic flux, a core mounted on said support and arranged to supply magnetic flux to said core in response to a triggering signal and magnetic means for supplying flux from said core to said tines characterized in that said support is a circuit board, said tines are rigidly attached to said circuit board, said tines and said core are located on opposite sides of said circuit board, one end of said core is rigidly attached to one end of said circuit board, and said magnetic means includes an end magnet rigidly linking said tines and the other end of said circuit board, and magnetically linking said core and said tines whereby the operating components of said vibrating reed device are held in a rigid, highly stable configuration.
Claim 2
Dependent Claim
149 words
A vibrating reed device including a support, two tines mounted on said support and arranged to vibrate when stimulated by a pulsing magnetic flux, a core mounted on said support and arranged to supply magnetic flux to said core in response to a triggering signal and magnetic means for supplying flux from said core to said tines characterized in that said support is a circuit board, said tines are rigidly attached to said circuit board, said tines and said core are located on opposite sides of said circuit board, one end of said core is rigidly attached to one end of said circuit board, and said magnetic means includes an end magnet rigidly linking said tines and the other end of said circuit board, and magnetically linking said core and said tines whereby the operating components of said vibrating reed device are held in a rigid, highly stable configuration.
Claim 3
Dependent Claim
50 words
A vibrating reed device in accordance with claim 1 wherein said circuit board is made of a ceramic material having a coefficient of thermal expansion of 6.0 X 10 6 and said tines are made of a magnetic material having a coefficient of thermal expansion of 7.0 X 10 6.
Claim 4
Dependent Claim
59 words
A vibrating reed device in accordance with claim 1 wherein said tines are mechanically joined at their fixed ends by a spacer rigidly attached to said circuit board, said end magnet has an H-configuration and said spacer and said core have ends snugly fitted between the legs and on either side of the crossmember of said H-configurated end magnet.
Claim 5
Dependent Claim
39 words
A vibrating reed device in accordance with claim 3 wherein said core is notched and bent up at one end to form a pole piece and said circuit board has a slot for engaging the notch on said core.
Claim 6
Dependent Claim
53 words
A vibrating reed device in accordance with claim 4 wherein said core includes a bobbin, terminal pins molded in said bobbin and a coil wound on said bobbin and attached to said terminal pins, and said circuit board has circuit paths disposed adjacent to and in contact with each of said terminal pins.
Claim 7
Dependent Claim
31 words
A vibrating reed device in accordance with claim 1 wherein said tines cooperate with two fixed contacts and two moving contacts to form two moving contacts to form two contact sets.
Claim 8
Dependent Claim
20 words
A vibrating reed device in accordance with claim 6 wherein said fixed contacts are each mounted on a contact bracket.
Claim 9
Dependent Claim
60 words
A vibrating reed device in accordance with claim 7 wherein each contact bracket is a rectangular member having two ends bent up to form a finger base and a shoulder respectively, and each fixed contact is an elongated wire finger rigidly attached to a finger base at one end and deflected to press against a shoulder at the other end.
Claim 10
Dependent Claim
33 words
A vibrating reed device in accordance with claim 8 wherein the point of attachment between each finger and its associated finger base is centrally located with respect to the center of said shoulder.
Claim 11
Dependent Claim
27 words
A vibrating reed device in accordance with claim 9 wherein each contact bracket includes means for adjusting the position of said contact bracket on said circuit board.
