Abstract
Abstract A cable control system including an adjustment device comprising a housing, a conduit fitting member mounted for reciprocating movement within the housing and adapted to be connected to the conduit of a cable system through which a cable strand extends. A spring yieldingly urges the housing in one direction. A ratchet gear is rotatably mounted in the housing and supports a pinion gear which engages teeth on the conduit fitting member. The ratchet gear has teeth with a pitch diameter greater than the pitch diameter of the teeth on the pinion gear and the teeth on the pinion gear are larger than the teeth on the ratchet wheel so that there are a greater number of teeth on the ratchet wheel than on the pinion. A removable ratchet detent engages the teeth on the ratchet wheel. In one form, the device automatically adjusts to change the tension on the cable conduit. In another form, the device is unlocked to provide an adjustment.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
A cable control system including an adjustment device comprising a housing, a conduit fitting having teeth thereon mounted for reciprocating movement within said housing and adapted to be connected to the conduit of a cable system through which a cable strand extends, a ratchet gear rotatably mounted in the housing and supporting a pinion gear which engages teeth on the conduit fitting member, said ratchet gear having gear teeth with a pitch diameter greater than the pitch diameter of the teeth on the pinion gear and the teeth on the pinion gear being larger than the teeth on the ratchet wheel so that there are a greater number of teeth on the ratchet wheel than on the pinon, and a retractable ratchet detent engaging the teeth on the ratchet wheel.
Claim 2
Dependent Claim
130 words
A cable control system including an adjustment device comprising a housing, a conduit fitting having teeth thereon mounted for reciprocating movement within said housing and adapted to be connected to the conduit of a cable system through which a cable strand extends, a ratchet gear rotatably mounted in the housing and supporting a pinion gear which engages teeth on the conduit fitting member, said ratchet gear having gear teeth with a pitch diameter greater than the pitch diameter of the teeth on the pinion gear and the teeth on the pinion gear being larger than the teeth on the ratchet wheel so that there are a greater number of teeth on the ratchet wheel than on the pinon, and a retractable ratchet detent engaging the teeth on the ratchet wheel.
Claim 3
Dependent Claim
19 words
The cable control system set forth in claim 1 wherein said housing includes a cover supporting said ratchet detent.
Claim 4
Dependent Claim
15 words
The cable control system set forth in claim 2 wherein said cover is bodily removable.
Claim 5
Dependent Claim
22 words
The cable control system set forth in claim 2 wherein said cover is pivotally connected to said housing by an integral hinge.
Claim 6
Dependent Claim
20 words
The cable control system set forth in claim 1 wherein said ratchet gear and pinion gear comprise a single body.
Claim 7
Dependent Claim
17 words
The cable control system set forth in claim 1 wherein said conduit fitting has longitudinally spaced teeth.
Claim 8
Dependent Claim
14 words
The cable control system set forth in claim 6 wherein said teeth are annular.
Claim 9
Dependent Claim
26 words
The cable control system set forth in claim 1 including integral means on said housing adapted to hold said housing on a wall or the like.
Claim 10
Dependent Claim
28 words
The cable control system set forth in any of claims 1-8 wherein said ratchet detent is yieldingly urged against said ratchet wheel such that the device operates automatically.
Claim 11
Dependent Claim
65 words
The cable control system set forth in any of claims 1-8 wherein said ratchet device is rigid and must be manually moved out of engagement with the teeth, said device including a spring yieldingly urging the device in one direction such that when the ratchet device is moved out of engagement with the teeth, the spring functions to move the conduit away from the housing.
