First Claim
Patent Images
1. In combination with a drill, the drill having a drill body and having a drill chuck attached, an angle attachment coupling comprising:
- an angle attachment, the angle attachment having an input shaft, having an output shaft, and having an input nut attached to the input shaft;
a coupler, the coupler having a socket which is removably seated onto the input nut and having a coupler shaft which is removably secured in the drill chuck; and
a sleeve, the sleeve having a first end which is removably secured onto an input rim on the angle attachment and having a second end which is removably secured onto a drill body rim on the drill body so that the angle attachment is held in fixed relation to the drill body while the coupler transmits rotation of the drill chuck to the input nut.

Abstract
An angle attachment is attached to a drill without removing the drill chuck by securing the shaft of a coupler in the drill chuck and seating the coupler on the nut of either shaft of the angle attachment, securing the angle attachment to the drill with a sleeve, and threading an attachment chuck onto the shaft of the angle attachment which is not coupled to the drill chuck

6. In combination with a drill, the drill having a drill body and having a drill chuck attached, an angle attachment coupling comprising:
-
an angle attachment, the angle attachment having an input shaft, having an output shaft, having an input nut attached to the input shaft, having an output nut attached to the output shaft, and having an attachment chuck removably attached to the output shaft, the output shaft being generally identical in size and form to the input shaft, and the output nut being generally identical in size and form to the input nut; a coupler, the coupler having a socket which is removably seated onto the input nut and having a coupler shaft which is removably secured in the drill chuck; and a sleeve, the sleeve having a first end which is removably secured onto an input rim on the angle attachment and having a second end which is removably secured onto a drill body rim on the drill body so that the angle attachment is held in fixed relation to the drill body while the coupler transmits rotation of the drill chuck to the input nut, the sleeve being secured onto the input rim by tightening a first bolt using a chuck key and the sleeve being secured onto drill body rim by tightening a second bolt using the chuck key.

7. A method for coupling an angle attachment to a drill, the drill having a drill body and having a drill chuck attached, comprising the steps:
-
providing an angle attachment coupling comprising; an angle attachment, the angle attachment having an input shaft, having an output shaft, having an input nut attached to the input shaft, having an output nut attached to the output shaft, and having an attachment chuck removably attached to the output shaft, the output shaft being generally identical in size and form to the input shaft, and the second nut being generally identical in size and form to the first nut; a coupler, the coupler having a socket which is removably seatable onto the input nut and having a coupler shaft which is removably securable in the drill chuck; and
;a sleeve, the sleeve having a first end which is removably securable onto an input rim on the angle attachment and having a second end which is removably securable onto a drill body rim on the drill body so that the angle attachment is held in fixed relation to the drill body while the coupler transmits rotation of the drill chuck to the input nut; securing the coupler in the drill chuck; seating the coupler onto the input nut; securing the sleeve onto the input rim; and
securing the sleeve onto the drill body rim with the angle attachment held in fixed relation to the drill body while the coupler transmits rotation from the drill chuck to the input nut.
