Abstract
A rotary temperature control device which includes a vent pulley, a control pulley having a bevel gear associated therewith, a flexible cable which extends from the control pulley to the vent pulley and a shaft having a pinion gear associated therewith for driving the bevel gear, thus providing rotational movement to the vent pulley. The cable preferably has first and second ends and an intermediate portion therebetween which defines first and second segments, wherein the first and second ends are secured to the vent pulley while the intermediate portion is secured to the control pulley.
Claims24
A rotary temperature control device comprising:
- (a) a vent pulley;
- (b) a control pulley having gear means associated therewith;
- (c) flexible cable means extending from the control pulley to the vent pulley for providing rotational movement to the vent pulley in response to rotational movement of the control pulley;
- and
- (d) a shaft having gear means associated therewith, wherein the shaft gear means is configured and adapted to operatively cooperate with the control pulley gear means for transmitting rotational motion from the control pulley to the vent pulley.
A rotary temperature control device comprising:
- (a) a vent pulley;
- (b) a control pulley located a distance from the vent pulley;
- (c) a flexible cable extending from the vent pulley to the control pulley and back to the vent pulley;
- wherein the cable is adapted and configured to transmit rotational movement from the control pulley to the vent pulley through tension of a segment of the cable;
- and
- (d) means for rotating the control pulley.
A rotary temperature control device comprising:
- (a) a vent housing having a vent pulley mounted therein, a vent spring secured to the vent pulley and stationary means for maintaining the vent pulley in a predisposed position for shipping;
- (b) a control housing located a distance from the vent housing having a control pulley mounted therein, a beveled gear mounted in the control pulley and incremental adjustment means for incrementally adjusting the rotational movement of the control pulley;
- (c) a flexible cable extending between the control and vent housing having first and second ends and an intermediate portion therebetween for defining first and second segments;
- the first and second ends secured to the vent spring and the intermediate portion secured to the control pulley, the first segment being in tension upon rotational movement of the control pulley in a first direction and the second segment being in tension upon rotational movement of the control pulley in a second direction;
- and
- (d) a shaft having a beveled pinion gear mounted thereon, wherein the pinion gear is configured and adapted to operatively cooperate with the bevel gear for transmitting rotational motion to the control pulley;
- wherein the shaft includes alignment means for aligning the shaft in a predisposed position for attachment of the control housing.
