SEECIICATION forming part of Letters `llatent No. 286,294, dated October 9, 1883.
` Appiicafiou med .my 3,1593. (Moden T 0 all", whom, it rn/nr/g/ concern: Be it known that I, J OHNA. IIAASE, aeitizen of the United States, residingat No. 116 Vanhorn street, in the city and county of Philadelphia and State of Pennsylvania, have invented a 'new and useful Improvement in Hand "Drilling-Machines for Drilling Metal; and I do hereby declare that the following is a full and exact description of the invention, reference being had to the accompanying drawing and to the letters of reference marked thereon. l
My invention relates to machines, called ,ratohet-drills, all of which. have a single handle for revolving lthe drill when required. Such machines stop at every repeated stroke, the drill running half-.time only, and this, causes side strain or friction in large holes.
My machine for small holes Q not requiring much labor) runs almost continuously, and while drilling largeY holes, by operating the 'two handles and running at the ordinary speed I avoid friction.
The drawing is a side view-of the machine. A is the set (or extension) screw; B, spindie; Gand C, ratchet-wheels; D and l), bodies; E and E, handles. In each body is a pawl,
(or catch which slides centrally to and fro and catches into the teeth of the ratchet-wheels, and a spiral spring in. each body keeps the said pawls properly in place.
In use a device, commonly termed old man, is clamped -on the work to be drilled, which device is provided with a projecting arm for the point of set-screw A to bear against,
Vthus forcing the drill that is placed in the other end of the spindle into the metal Vto be drilled.
I claini- The combination, as herein described and shown, of lthe spindle' B, two ratehet-wheels, C, rigidly connected thereto, and having teeth inclined in the same direction, two bdies, I),
each containing' a pawl and spring for holding
