Description:

H. V. Carpenter - patent attorney

My invention relates to an improvement in ratchet wrenches, and the objects of my improvement are: First, to include all of the useful features of ratchet wrenches now hi use; and second, to add a means of rapidly screwing or unscrewing a nut or bolt as soon as it is sufficiently loosened to turn easily, thus speeding up materially the work of applying or removing bolted parts.
