operated by hand and by means of frictionrolls, the invention consisting in devices and combinations-of devices hereinafter described and specifically set forth in the claims, the object of the invention being t-o provide for readily changing the mechanism so as to v make a right-hand7 or a-left-hand machine, and to otherwise facilitate manipula, tion of the machin`e.
In the drawings, Figure lisis an elevation of a machine embodying my invention.
2 is a vertical longitudinal section of the -tion on the line 6 6 in Fig. 4. Figs. l and 2 are drawn on ,a smaller scale than the re` mainder of the figures. f
The drill-spindle Ais provided with a re'c. tangular socket a. to receive the drill B. The upward part-C of the spindle A is preferably joined to the body of the spindle by means of a rectangular part b, entering a corresponding socket, as shown. The part C consists of the threaded portions c and cl to move longitudinally one on the other for the purpose of causing the drill to be fed forward in the usual manner. Pins e inserted through holes in the body of the spindle and in the shank of the drill' and the part C, and held therein bymeans of springs f, form a convenient means for keeping the drill and part C from being accidentally disconnected from the body of the spindle. Surrounding the spindle A is a iiangeD, having a lateral extension g, provided with a socket in which ts to revolve therein a part of the operatinglever E. The iiange D is held in longitudinal position on the spindle A by means ofcollars h, fasten-ed to the spindle, as shown.
Vithin the iiangeD and between this flange and the spindle is a cylindrical casin g F, formed in such a manner as to provide slots t' to receive the friction-rolls jand maintain them in such position that eachof them will be parallel to the spindle and will be brought intol contactvwith the spindleand the interior surface ofthe flange D, as hereinafter specified.
The lever E has on its innerend a knob or projection 71, eccentrically located on said end and formed to move freely in a slot l in the casing F, this slot being parallelto the spindle. The lever F. has a circumferential groove m, so that a pin n, extending through the extension g in position to be in said slot, will keep the lever from moving endwise in the extension g. On the lever is a collar G, having an interior shoulder o, between which and a shoulder p on the spindle is a spiralspring q. On. the lever is a projection fr, which enters a longitudinalslot sin the interior of the collar G. Thus ythis collar may be moved endwise on the lever to bring the collar into and out of contact with the end of the extension g, the spring acting to force the collar against said end, while the collar will revolve with the lever owing tothe pro- .jection r in the slot s.V The adjacent ends of the collar G and the extension g aregrooved radially, as illustrated byFigo, so as to to present two converging planes u n, foreach roll j, which planes are approximately tangential with reference to the cylindrical spindle A. Therefore when each roll j is held by the casing F so as to be out of contact with either of the corresponding planes the flange D may be revolved freely on the spindle. When each roll is carried by the casing F, so

as to be pinched between either of said planes Y and the spindle, then the spindle may be revolved in that direction by means of the lever, and the lever may be swung in the reverse direction without rotating the spindle, according to the well-known action of frictionrolls. Any number of friction-rolls j and slots 'i therefor in the casing F may be employed in carrying out my invention. I prefer to employ three rolls, as shown.
The operation of the machine will appear from the above description. By pressing the collar G out of clutch with the extension g, as above set forth, and rotating the lever E in the required direction, the casing F will be rotated by means of the projection 7;, so as to carry the friction-rolls into position to cause the spindle and drill to be revolved by means ot' the lever as desired, the collar G having been allowed to engage with the end of the extension g to hold the casing F and friction-rolls in said position. It will be noticed that each wall of each slot z' performs two offices, one to force the frictionroll out of position to come into contact with one plane u and to carry and hold the roll sufficiently close to the other plane as to be readily caught between the plane and the spindle when the lever is swung in the direction for rotatingr the drill.
I -ain well aware that friction-rolls have heretofore been employed in a hand drillingmachine, and, also, that in such machines means have been adapted therein for carrying the rolls from one position to another to be pinched between either of two oppositelyinclined planes for the purpose of operating a drill in either direction. The devices herein described and claimed for carrying out the several purposes of this class of machines are, I believe, not only novel, but very useful with respect to strength, reliability, eliiciency, and convenience.
I claim as my inventionl. In a hand drilling-machine the combination of the drill-spindle, a flange surrounding the spindle provided with oppositely-inclined planes, a casingsurrounding the spindle between said flange and spindle and provided with several slots for friction-rolls, rolls in said slots, and devices embodying a lever revoluble about its axis and at right angles to said spindle for rotating said casing in either direction, substantially as and for the purpose set forth.
2. The combination of a drill-spindle, a flange surrounding the spindle and provided with oppositely-inclined planes on its interior surface and with a lateral extension, a casing having a slot between said spindle and lian ge, a roll in said slot, a lever having a bearing in said extension to rotate therein, and an eecentric projection on said lever to engage with said easing, substantially as specified.
3. The combination of a drill-spindle, a flange surrounding said spindle and provided with oppositely-inclined planes, a easing between said flange and spindle having a slot, a roll in said slot, a lever to rotate in said fia-nge, or lateral projection thereof, an eccelltrie projection on said lever to engage with said casing, and a collar on said lever to engage with the lever and with said fiange or projection thereon to form an adjustable clutch, substantially as and for the purpose set forth.
4. In combination with a drill-spindle, a flange surrounding the spindle and provided with oppositely-inclined interior planes, and a casing for holding and changingthe position ot friction-rolls therein, a lever extending laterally into said flange to rotate therein and adapted to engage with said casing, and
'an adjustable clutch embodying a spring for secu ring said lever, fiange and casing in the required position for operating the drill in either direction, substantially as specified.
5. In ahand drilling-machine operated by means of friction-rolls in either direction as set forth, a casing to receive the friction-rolls, guide the rolls into the required position and maintain them in that position, in combination with a lever for operating the machine, said lever having an eccentric connection with said casing, and adapted to rotate on its axis, for moving said casing to carry the frietion-rolls into said position, substantially as specified.
