Abstract
A sewer augering apparatus and more particularly a sewer augering apparatus having a power feed and manual lock apparatus with actuation thereof by an, axially slideable actuator.
Claims18
In a sewer augering apparatus wherein an elongated flexible snake is moveable in axial rotation as it progresses in an axial direction, an apparatus for controlling actuation of such a snake element comprising:
- feed means cooperable with such a snake element by selective engagement with exterior peripheral portions thereof to impart axial feeding impetus to such a snake element in response to axial rotation thereof;
- lock means selectively engageable with such a snake element to selectively lock such a snake element against axial movement;
- and
- actuator means comprised of an elongated actuator element which is coaxially arranged with respect to such a snake element and is manually slideable axially of such a snake element between axially spaced positions including a feed actuating position whereat said actuator means is cooperable with said feed means to engage said feed means in operative engagement with such a snake element, and a lock actuating position spaced axially from said feed actuating position and whereat said actuator means is cooperable with said lock means to maintain said lock means in operative engagement with such a snake element.
In a sewer augering apparatus wherein a flexible elongated snake element is selectively feedable in an axial direction from a canister by a power feed means which is engageable with such a snake element and is operable by relative rotation between the power feed means and the snake element, and a lock means is operable to selectively engage and lock such a snake element against axial movement in either axial direction with respect to such a canister, an actuator means for actuating such feed and lock means comprising:
- an elongated sleeve means encompassing an axially extending portion of such a sewer augering apparatus through which such a snake element extends;
- said sleeve means including a first actuator portion located for selective actuation of such a feed means upon movement of said sleeve means in one axial direction to a first axial position;
- and
- said sleeve means including a second actuator portion located to actuate such a lock means upon movement of said sleeve means axially to a second axial position spaced from said first axial position.
In a sewer augering apparatus wherein a flexible elongated snake element is selectively feedable in an axial direction from a canister, the combination comprising:
- an elongated, generally cylindrical spindle means having an axial through opening adapted to have such a snake element extending therethrough and means adjacent one axial end of said spindle means adapted for connection to such a canister for concomitant rotation of said spindle means with such a canister;
- power feed means carried by said spindle means and engageable with such a snake element for axial feeding thereof from such a canister and through said spindle means;
- lock means carried by said spindle means and operable to selectively engage and lock such a snake element against axial movement in either axial direction with respect to said spindle means;
- an elongated sleeve means coaxially encompassing said spindle means;
- means mounting said sleeve means with respect to said spindle means in a manner that said sleeve means is axially and rotationally moveable with respect to said spindle means;
- said sleeve means including a first actuator portion located for selective actuation of said power feed means upon movement of said sleeve means in one axial direction with respect to said spindle means to a first axial position;
- and
- said sleeve means including a second actuator portion located to actuate said lock means upon movement of said sleeve means axially with respect to said spindle means to a second axial position spaced from said first axial position.
