screw 21 or the like to the outer side of the slide 1.4 at the upper'edge thereof and overlapping the iange or guide 12 above the channel 13. Said stop 21 is movable between a pair ot' stops 23 depending from the opposite ends of overlapping` slotted bars 23 secured on the upper edge of the flange or guide 12 by means of screws 23" which extend through the slots of saidbars. l/Vhen the screws are loosened, the bars 23 can be adjusted longitudinally to position the stops 23 according to the desired adjustment, for determining the length of thefmortise or slot. The flange or guide 12 is preferably graduated, .as at A21, to assist in positioning the stops 23.

'A depth slide 24 is mounted for movement toward and away 'from the object andthe base 7. Thus, said slide 24'has sleeves 27 slidable on rods 25 `carried by and extending horizontally from the base? below the guide 12 and slide 14.

A depth gage is provided for limiting the movement oft the slide 24 on the rods 25 toward the base 7 and object, to thereby determine the depth of a mortise. This gage includes a rod 33 vsecured to and extending from the base 7 at one endthereot adjacent to andA parallel with one of the rods 25, and stop arm 33 mounted on said rod 33 for sliding and turning movements. he arm 33 has a handle 35 for swinging it, to move said arm against the corresponding rod 25,

i as seen in dotted lines in Fig. 1, or to swing said arm away from said rod 25, as seen in full lines yin said Fig. 1. An adjusting collar 34 is slidable on the rod 33 and is secured in place by means of a set screw 34 carried by the collar, and saidcollar can be readily adjusted to position the stop 33 and limit the movement thereof on the rod 33 toward the base. When the arm 33 is swung away from the corresponding rod 25, the slide 24 can move up to the base 7, 4but when said arm 33 is swung against said rod 25, it will stop. the movement of the slide 24 at a predetermined position, to thereby limit the depth of the mortise accordingly.

The slide or member 24 has a guide or slideway 27 arranged vertically and rising perpendicularly from the lower edge portionof said slide between theends of said slide, and a slidevvor block is slidable upwardly and downwardly in said guide or slot 27, and has a circular opening or bore 23 extending therethrough transversely ot the slide 24 and guide 27. The slide 40 has a clamping plate y40 at one side held by a clamping bolt 40 to clamp said slide in its adjusted position.

The auger bit 43 or equivalent tool is rotated by a driving or operating mechanism ley wheel 42 is secured on the spindle 37 between said bushings for retaining the spindle in place, and a belt 44 passes around said pulley vwheel for rotating said spindle, and is guided between rollers 45. The shaft or shank. 33 which carries the bit. or tool 43v .is

.received by the tubular spindle 37, and said spindle has a screw-threaded portion 37 at that end opposite to the bit into which the screw-threaded terminal 38 of the shaft 33 isl secured, for fastening said shaft to the spindle. rlhe shaft has a collar 33"thereon to bear against that end .of thespindle opposite to the screwthreaded end, :tor fastening the shaft securely to the spindle, and the bit or tool 43 projects beyond the collar 38.

rThe bushing 36' is veXteI'ided from'jthe yokeA 26 in order to `enter the opening-23 of the 'slide or block 40so `as to provide a detachable slip connection between the driving mechanism and the portable or movable device. The extended portion ,of the bushing 36 is conveniently slipped in the opening 28,

Y for assembling the mechanism and device,

and in order to hold them assembled, said bushing has an annular groove 39 -in the eX- tended portion thereof to receive a ballor catch 41 vslidable in the slide or block 40 and 'projected' by a spring 41 coninecl be hind said ball. When the slide 40 and bushing 36 are fitted together, the ball or catch r41 is pressed into the boire or socket', and

when the parts are moved together, said ball will snap into the groove 39, thereby hold-I ing the yoke 26 and slide 40 together, but permitting said parts to turn relatively, when the device is moved longitudinally.

lThe bushingv36 can thus turn ink theysli'del 40. llVhenthe drivingmechanismand dey vice are thus assembled, the bit or tool can be attached by sliding the shaft 3S into Vthe spindle 37 and screwing said shaft into place. The bit is thus secured to the rotary spindlefh37 o't the driving' mechanism, and.. vsuch spindle and bit will be adjusted with the slide 40 upwardly and downwardly. rthe terminal portion Aor,lnishing 36 of the driving mechanism is thus convenientlyassembled with the device for adjustment therewith, to positionthe bit or tool accordingly, andina like manner other devices yor attachments can be used interchangeably with the mortising device, by

having such devices eachv equipped with a slide or block to fit on the bushing 36. Various devices or attachments for doing different kinds of work can thus be used interchangeably with the driving mechanism.

A gage is provided for readily determining the transverse positions of the mortises or slots in the stiles or other objects. Thus, the slide or member 24 has a slot 50 extending parallel with the guide 2T at one side of the slot thereof, and bolts or stems 51 are disposed in the slot for longitudinal adjustment in said slotto different positions, and have stops or heads 52 for the contact of the block or slide 40 to limit the upward and downward movement thereof. Nuts 53 are threaded on the boltsor stems 51 for clamping the stops 52 in their desired adjustments, and graduations 54 can be provided along the slot 50 for conveniently positioning the stops 52. Thus, when the bolt 40 of the slide 40 is loosened,.said slide can be readily moved from one 'position against one stop 52 to the other position against the other stop 52, and said stops; thereby enable the position of the slide or block 40 4to be changed quickly, for cutting parallel mortises or slots. By adjusting the stops 52, the transverse positions of the mortises or slots with respect to the object can be adjusted, to space the mortises or slots the desired distances from the edges of the object and from one another.

The slide or work holder 14 has an opening extending from one side to the other, to accommodate the auger bit 43 in the different positions of said bit and slide, and said slide has vertical openings or slotsA 61 in the ends thereof for the reception of the window frame stile 62, board or other object which is inserted on edge into the slide, as seen in Fig. 3.

A work clamp is: carried by the slide or holder 14 and includes a stub shaft 63 mounted for turning movement in one end portion of the slide 14 and having' a cam 64 working within a slot in said slide to bear against the stile or board 62, and clamp same against the back of the slide or holder 14. A hand lever 62 is secured to the shaft 63, and when raised will turn the cam 64 to bind the object in place.

In using the device, the slide or block 40 is assembled with the driving mechanism, by fitting the bushing 36 in said slide, and the ball 41 will snap into the groove 39, to hold the mechanism and device assembled. The bit or tool 43 is then attached b y inserting the shaft or stem 38 thereof into the tubular spindle 37 and screwing said shaft into place with the spindle. The stile or board 62 is then inserted into the slide or holder 14, the bit 43 being retracted, and said stile Orboard is clamped in said slide or holder swinging the hand lever or arm 66. The stile or board is thereby securely held in potermine the upper and lower positions of the auger bit 43. Thenby clamping the slide or block 40 in one position against the corresponding stop 52, and after swinging the stop arml 33 to position againstthe corresponding rod 25, the slide 24 is moved toward the work, thereby presenting the bit 43 to the face of the stile or board 62, and by swinging the lever 17, the slide 14 and stile 62 are slid longitudinally, for cutting or routing a mortise in the stile at the de sired transverse posit-ion and of the predetermined depth and length. The depth of the mortise is determined by the position of the stop arm 33, and the length of the mortise by the stops 23. By swinging the stop arm 33 out of the way of the slide 24, the bit'43` can now be moved further int-o the stile 62, to pass entirely through the' stile, and the slide 14 is then moved so that the bit cuts a' slot 67 in the stile, but the slide 14 is not moved sufficiently to bring the stop 21 aga-inst the stops 23, thereby making the slot 67 of shorter length than the shallow mortise 68.l Theinortis'e thus formed provides a slot`l 67 through the stile or board, with shallow portions beyond the ends of lsuch slot, for receiving the housing of a sash cord pulley used on window frames, as well known.

By loosening the block or slide 40 and bringing same against the other stop 52, a parallel'mortise of the same kind can then be cut inthe stile or board.,

Various sizes and positions of mortises can thus be produced, which is especially useful for making the pulley mortises of window frames, and bits 43 of different diameters can be used interchangeably, for making" mortises of different widths. The lengths and depths, and also the transverse positions of the mortises can be readily determined by the gages and adjustments provided. Furthermore, by loosening the screws 11 and turning the plate or member 10, the slide 14 and object can be positioned either at right angles or at an acute or obtuse angle with the bit 43, to make the end walls of the mortises either at right or other anglesv with the sides of the objects.

The work can be done quickly and easily, without the labor and time required as when doing the work with an ordinary bra-ce and bit. Furthermore, the work is done accurately and neatly, and without a possibility of Al'Ji spoiling the job, because the adjustments `made will define and limit the movement of the bit or cutter. f i
