Abstract
Abstract A mechanical channel selector device for the remote switching of channels of a television receiver includes a switching mechanism coaxially mounted to the television receiver channel shaft and operatively connected to a manual control mechanism. The switching mechanism includes a switching disc having a series of notches corresponding to the television channels on the inside surface which cooperate with a pawl member pivotally mounted to a switching actuator lever coaxially mounted on the disc and operatively connected to the control mechanism. The control mechanism includes a spring biased control knob movable between an at rest position and an actuated position. Movement of the control knob results in the pivotal movement of the actuator lever and the pawl member engaging a notch on the switching disk to rotate the television receiver channel shaft to the next channel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
198 words
A mechanical channel selector device for the remote switching of channels of a television receiver having a housing and a receiver channel shaft, including in combination: switching means coaxially and adjustably mounted to the television channel receiver shaft; bracket means mounted to the television receiver housing adjacent said switching means; cable connector means slidably mounted to the television receiver housing by said bracket means and attached to said switching means, said cable connector means including a cable member positioned within a sleeve member, said sleeve member adapted to be engaged by said bracket means to fixedly anchor said sleeve member, with said bracket means providing alignment of said connector means with said switching means to permit the axial movement of said cable member therein; and control means operatively connected by said cable connector means to said switching means said control means being rotatable between a first at rest position to a second actuated position, said rotational movement of said control means from said first to said second position causing said cable member to axially move therewith and rotate said switching means and the television receiver channel shaft to the next television receiver channel to predeterminely index the same.

A mechanical channel selector device for the remote switching of channels of a television receiver having a housing and a receiver channel shaft, including in combination: switching means coaxially and adjustably mounted to the television channel receiver shaft; bracket means mounted to the television receiver housing adjacent said switching means; cable connector means slidably mounted to the television receiver housing by said bracket means and attached to said switching means, said cable connector means including a cable member positioned within a sleeve member, said sleeve member adapted to be engaged by said bracket means to fixedly anchor said sleeve member, with said bracket means providing alignment of said connector means with said switching means to permit the axial movement of said cable member therein; and control means operatively connected by said cable connector means to said switching means said control means being rotatable between a first at rest position to a second actuated position, said rotational movement of said control means from said first to said second position causing said cable member to axially move therewith and rotate said switching means and the television receiver channel shaft to the next television receiver channel to predeterminely index the same.
Claim 3
Dependent Claim
35 words
The mechanical channel selector device in accordance with claim 1 further including spring bias means engageable with said control means to return the same from said second actuated position to said first at rest position.
Claim 4
Dependent Claim
73 words
The mechanical channel selector device in accordance with claim 1 wherein said switching means includes a spline member adapted to engage and rotate the receiver channel shaft and a switching disc portion mounted on said spline member and rotatable therewith, with said switching disc portion being attached to said cable connector means and being rotatable by the movement of said cable connector means to index the receiver channel shaft to the next channel.
Claim 5
Dependent Claim
94 words
The mechanical channel selector device in accordance with claim 3 wherein said switching disc portion includes a disc member having a plurality of recesses positioned on the inside surface thereof and a control lever coaxially mounted to said disc member and attached to said connector means and including a pawl member which selectively engages said recesses positioned on said disc member, such that upon movement of said cable connector means said pawl member engages said recesses to rotate said member and said spline member to index the receiver channel shaft to the next channel.
Claim 6
Dependent Claim
31 words
The mechanical channel selector device in accordance with claim 1 wherein said control means includes a housing having a control knob pivotally mounted therein and operatively connected to said connector means.
Claim 7
Dependent Claim
28 words
The mechanical channel selector device in accordance with claim 1 wherein said switching means includes indicia thereon which indicate the channel to which the television receiver is tuned.
Claim 8
Dependent Claim
81 words
The mechanical channel selector device in accordance with claim 5 wherein said housing further includes a ratchet gear having indicia thereon mounted adjacent said control knob and said control knob includes a pawl member mounted thereon and engageable with said ratchet gear, such that upon said pivotal movement of said control knob from said first to said second position, said pawl lever engages said ratchet gear to rotate the same to indicate the channel to which the television receiver is tuned.
Claim 9
Dependent Claim
28 words
The mechanical channel selector device in accordance with claim 1 wherein said control means includes indicia thereon which indicate the channel to which the television receiver is tuned.
