Abstract
The present invention is a wire puller, which pulls line through conduit, by employing the motor force of a standard right-angle power drill, and an operator to keep the line frictionally coupled to a spool on the wire puller. The apparatus consists of a stand and a frame, onto which is mounted a drive shaft, one end of which is sized to receive the jaws of a standard right-angle power drill. A drill restraining mechanism, also mounted onto the frame, allows the power drill to be positioned, such that actuating the drill turns the drive shaft, without requiring the wire puller operator to hold the drill, and without requiring the wire puller operator to continually depress the drill trigger switch.
Claims20
An apparatus comprising:
- a frame having a drive shaft mounting portion and a power drill restraint portion, wherein the power drill restraint portion is adapted to register a standard right-angle power drill with the frame and with a switch lever;
- a drive shaft mounted with the frame in the drive shaft mounting portion, wherein the drive shaft may be rotated about its longitudinal axis and a first end of the drive shaft is sized to be coupled with the jaws of a power drill;
- and
- a switch lever having an "off" position and an "on" position mounted in the power drill restraint portion, the switch lever being continuously retained in the "on" position to depress a trigger switch on a power drill when the switch lever is moved from the "off" position to the "on" position and when such a drill is mounted in the restraint portion and coupled to the drive shaft.
An apparatus comprising:
- a frame having a drive shaft mounting portion, a power drill restraint portion, and a forearm portion, wherein the power drill restraint portion is adapted to register a power drill with the frame and with a switch lever;
- a drive shaft mounted with the frame in the drive shaft mounting portion, wherein the drive shaft may be rotated about its longitudinal axis and a first end of the drive shaft is sized to be coupled with the jaws of a power drill;
- a switch lever that depresses a trigger switch on a power drill when such a drill is mounted in the restraint portion and coupled to the drive shaft;
- a first spool mounted on a second end of the drive shaft opposite the first end;
- a second spool mounted on the forearm portion of the frame;
- and
- a stand attached to the frame, such that the frame can pivot to allow the forearm portion to rest above or below the height of the stand.
An apparatus comprising:
- a frame having a drive shaft mounting portion and a power drill restraint portion, wherein the power drill restraint portion is adapted to register a power drill with the frame;
- a drive shaft mounted with the frame in the drive shaft mounting portion, wherein the drive shaft may be rotated about its longitudinal axis and a first end of the drive shaft is sized to be coupled with the jaws of a power drill;
- and
- a switch lever having an "off" position and an "on" position mounted on the frame, the switch lever being continuously retained in the "on" position to depress a trigger switch on a power drill when the switch lever is moved from the "off" position to the "on" position and when such a drill is mounted in the restraint portion and coupled to the drive shaft.
