Application filed June 5, 1812. Serial No. 701,939.

cs' ccialiy to tools provided with spindles h ed to be driven at (41H! rent speeds.

bne of the objects of the invention isto t ic change of speed may be readily accent-- zed 7 .her objects to provide a device of this character which is simple in its constrnction, and therefore not liable to get out order; which is c'ificient in use, and which will he comparatively inexpensive to n'ianni'acture, i

1. l 1 objects will in part be obvious, and in partno pointed out hereinafter. Y A

in the accompanying drawing showing an iiiustra tire embodiment of this invention and which the some reference numeral rcii'ers to similar parts in the several figures, Figure 1 is a view in side elevation showing the invention as applied to a breast drill. is a sectional view on a larger scale taken on the line 2--2 of Fig. l. 3 a part sectional view taken on the line 3--3 of Fig. 5.

lit the illustrative embodiment-shovvn in the drawings, the invention is shown as lociug applied to a breast drill, but it will, of course, be understood that it couldbc ap plied to other-tools or machines Withoutin any Way departing from the spirit of the invention. v

in the drawings, 1 represents a "frame in which is rotatehly mounted spindle 2 provided it; its outer end with a chuck 3, of the use a1 character, adapted to hold the drill bit, and secured to the inner end" of the spindle 2 are two bevel gears i and 5. A breast plate 6 supported by the frame in the usual manner, and the frame is also provided with the usual handle 7. The frame is provided with two sockets 8 and 9 which are parallel with one another and Whichare at rightangles to the axisot' the spindle 2. These sockets adapted to receive the axle 10 or a dri ing Wheel 11' which is provided. with handle 18 by means of which the Wheel is rotated. The parts are so adjusted that when tfle axle i is positioned in the socket 8 the outer gear teeth 152 Will engage with the gear on the spindle 2, and the inner gear teeth 13 will be out of engagement with,

either of the gears l and on the spindle. lironi this it will be seen that us the handle ii is r ated, 2i rapid .l'lllTJQllitlll'i] will be given to the chuck 3. By piecing the axle in the other socket 9, the inner teeth 13 on the Wheel 11 will engage the gear Wheel 4 on the spindle 2 and the outer gear teeth will be out of engagement with either of the and hour which it will be seen that, when the parts are so positioned, ro-- tation oi the Wheel ll. will cause a slow movement of the chuck 3.

In order to icinovahly hold the axle 10 in POL-31151011 Within either me of the sockets i 8 or i), the clinic is provided witlr'an annular roove with Wt) i let-hing member i6 adapted to e'xteinl ihroi a slot formed sition as by means of a spring 18, one end oi which engages the iiigenpicce l? and the other end of which engages the frame 1.

The operation of the device, which should be apparent from the drawings, is as follows: Assuming the Wheel ill. tobe positioned as shown in, l 1, in which position the chuc l'iigh speed, it it desired to drive the chuck at its low speed, it merely necessary to depress the finger-piece 17, which will, of course, causeihe locking member 16 to move out of engagement with the annular groove in the axle 10, indicated in dotted lines in Big 2. Thv trie may then be withdrawn from the socket S and inserted in socket 9, after which, upon relieving the pressure on the linger-piece 17, the spring 18 Will cause the locking member 16 to assume its normal or looking position, thereby retaining the axle in place.

Having descrihez'i this invention in connection with the illustrative embodiment thereof, to the details of which disclosure the invention is not, of course, to be limited, What is claimed as new and what is desired to be secured by Letters Patent is set forth in the appended claims:

3 is adapted to be driven at its Y l. in a tool, in combination, a frame pro lul 'vided with two sockets, a spindle rotatably mounted in the frame and two gear wheels mounted thereon, a driving wheel. provided with eencentriea ily arranged gear teeth adapted to enga 'e with said gear wheels, said drivingwheel being provided with an axle adapted to engage either one of Said sockets, said axle being provided with an annular groove, and a locking member extending within said sockets intermediate the ends thereof and adapted to engage said annular groove to loot: the axle in position.

2. In a tool, in combination, a. frame provided with two soolzets, a spindle rotatably mounted in the frame and two gear wheels mounted tl'iereon, a thriving wheel provided with concentrically arranged gear teeth adapted to engage with said gear wheels, said driving wheel being provided with. an axle adapted to engage either one of said sockets, said axle being provided with an annular groom, said frame being provided with a slot comnnnricating with sockets intermediate their ends and a locking member reeiprocatingly po itioned within said slot and adapted to nimal within said sockets and en, ige the annular groove in. to hold 1 in position.

3. In a tool, in. il'flllll' lll'zllitlll, a ill-nine proxided with two sin-hens, a swindle rotatably mounted in the frame and two gear mounted thermal, a driving wheel n-ovided with content al y arranged gear teeth adapted to or go with said gear wheels, said drivim;- .0l being provided with an a.-.le adal to engage either one of said wickets-u axle. being provided with an annular l-Yt, said frame being provided with a (a eonnnunicating With sockets intermediate their ends, a locking member wheels sail slot reciprocatingly positioned within t sockets and adapted to extend Within so. and engage the annular groove in to hold it in position, a finger-piece secured to said locking member for actuating the latter, and a spring engaging said fingerpieee and normally holding said locking member in its operative position.

4:. In a tool, in combination, a frame provided with two sockets, a spindle rotatably mounted in the frame and two gear Wheels mounted thereon, a driving wheel provided with concentrically arrangz-rd gear teeth adapted to engage with sa'l gear Wheels, said driving wheel being provided with an axle adapted to engage either one of said sockets, said axle being provided with an annular groove, said frame being provided with a slot connnunicating with said sockets intermediate their ends, a locking member r iciprocatingly positioned within said slot and adapted to extend Within said sockets and engage in the annular groove in said axle tohold it in position, said frame being provided witlran opening extending between said sockets and communicating with said slot, a finger piece positioned Within said opening and communicating with said locking member to actuate the same, and a spring operatively conneeted'to said finger piece and normally holding said locklng member in its operative position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
