:the top of said frame, said motor being adapted to communicate its power to said pulley 8, the belt 7 and the pulley 6, and consequently to the shaft 4 whereby the planing member 3 receives its rotary motion. Said member 3 consists of a head 11 and a series of blades or cutters 12, which latter occupy positions in recesses 13 in the peripheral rtion of said head and are retained therein by the blocks-.14 and the bolts 15, said blocks being of pyramidal or'wedge shape form to fit said recesses and bear respectively against the opposite side walls of said recesses and the sides of said blades, whereby the latter are adapted to be adjusted on the'head and retained firmly in set position thereon. The base of the chamher 2 is open, forming the throat 16 through which as the planing member revolves the cutting edges of the blades rotrude to sufficient extent to engage t e floor to be planed.

The frame of the device is supported on the shoes 17, which are substantially triangular in vertical section and have their inner portions separated from each other at the throat 16, the under faces of said shoes being plane surfaces so as to run flat on the floor, their upper walls 18 being inclined and slidingly engaging inclined surfaces 19 on the adjacent portions of the frame 1, said surfaces having depending flanges 20 on which are swivelled the bolts 21 whose threads engage threaded ears 22 on the upper walls 18 0f the shoes whereby, by operating said bolts, the shoes may be approached or se arated to raise or lower the frame and wlth it the cutter, thereb varying the depth of cut of the latter an at the same time, increasing or decreasing the width of the throat 16.

On each side of the shoes are the depth gages 23 which consist of horizontal mombers 24 one on each side of the shoes and having rising therefrom the arms or limbs lowered so as to set their-under sides to the required distance from the floor or boards to be planed. Then the shoes 17 are adjusted in accordance with the depth gages whereby the blades will plane the floor, to the required depth. Furthermore, when a length of a floor has been planed, the depth gage moves alon the shoulder formed on the floor by the p aned portion of the latter, and so assists in guiding the device true in its motions on the floor during the planing operation, see Figure 2.

, Attentionis drawn to the fact that the shoe that is foremost is raised to a small extent so that its under face .will ride on the unplaned floor or board, and that the shoe that is in the rear has its under face slightly lowered so as to ride on the planed floor or board, this being illustrated by the differences in the base lines in Figure 2.

In order to propel the device I provide the handles 28, whose lower portions are bolted to one or the other of the plates 19 of the frame as shown in Fig. 3 and fit between the lugs 29 onv said plate, see Fig. 2, which assist in preventing lateral shifting of the handle on said plate.

The handle may be placed on either end of the frame, as indicated in Figure 3, accord-- ing to the direction in which the machine is to travel. The upper portion of the shoes and undersides of the plates 19 are formed with grooves and tongues respectively as shown at 30, Figure 9, to assist in preventing the shoes from shifting laterally bolts 31 being also passed through said portions and 1 plates to provide firm connections of the shoes in position.

Connected with the shoes are the arms 32 on whose outer portions are mounted the horizontally extending rollers 33 which are adapted to bear against a side wall, surbase or wainscoting of an apartment in which the planing is being performed, thus assisting to guide the machine true in its movements in either direction.

The shaft 4 is shown extended in full lines, Figure 7 and in dotted lines Figure 6, so as to have mounted thereon the planing me ..*.ber 34 for side work when so desired.

In the frame above-the planing member 3 is the chamber 35 which containsthe fan or blower 36 whose shaft 37 is journalled in the wall of said chamber and carries the pulley 38 with which the belt 7 is adapted to contact tangentially to rotate said blower.

The chamber 35 communicates with the chamber 2 of the planing member 3 and is provided with an upwardly extending chute.

39 as an outlet .for shavings or cuttings occasioned in the planing of .the floor which are drawn therefrom by the operation of the blower.

In order to gather the shavings or cuttings, there is connected with the outer terminal of the chute 39 the sack or bag 40 which is in communication with said chute and attached thereto by-the catches 41 which are on the mouth of the bag and adapted to engage a shoulder 42 on the adjacent end of the chute, permitting also the ready removal of the bag from the chute and consequently from the device.

Secured to a proper portion of the frame 1, and rising therefrom is the standard 43 with "which is removably connected as at 44 the 46 of such diameter that it is above the floor so that the machine may be tilted and run over afioor without the planlng member contacting therewith.

47 designates a trimmer see Fig. 8 which consists of a circular blade wlth a toothed periphery, the hub portion of said blade being adapted to be mounted on the drivlng shaft 4 so that when required the periphery of the blade maybe presented to the end portions of the flooring boards and so cut off said portions and so trim the boards smooth and of the same length.

The driving shaft 4 is partly conical and partly cylindrical, the conical portion passing through a conical bore of the hub of the planer head 11, and the cylindrical part passing through the bushing 48 of the pulley 6, the outer terminal of said cylindrical part being threaded for the engagement of the nut 49, whereby when said nut is tightened, said shaft is held firmly and properly in position.

A portion of the said bushing is inclosed in a sleeve 50 and the latter is mclosed in an exterior stationary sleeve 51 on the frame of the device. the lubricator 52 which serves to direct oil to the bushing 48 for evident purposes. 1

The portion of the frame opposite to the nut 49 that forms the bearing for the adj a-. cent end of the shaft 4 carries the lubricator 53 which serves to direct oil to said end.

' -When the nut 49 is unscrewed the shaft 4 may be withdrawn from its position 'in the To said sle'eve51 is attached hub of the planing member without disturbbe discharged.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is Y 1. A frame consisting of a housing for a rotary cutter and a mounting for a motor for said cutter, a wall extending outwardly from said housing and inclined upwardly and backwardly; a shoe closing more or less the lower end of said housing and having a rear portion with an inclined upper face slidably engaging the lower face of said wall, and a screw for so slidably adjusting said shoe to both vertically adjust said cutter and also make wider or narrower the opening in the housing through which the cutter projects.

2. A frame consisting of a housing for a rotary cutter andamounting for amotor for said cutter, a wall extending outwardly from said housing and inclined upwardly and backwardly, a shoe closing more or less the lower end of said housing and having a rear portion with an inclined upper face slidably engaging the lower face of said wall, and a screw for so slidably adjusting said shoe to both vertically adjust said cutter and also make wider or narrower the opening in the housing through which the cutter projects, a handle secured to the face of the wall projecting from the housing, and a roller carried by a leg projecting down from said handle.

3. A frame, a rotary cutter mounted thereon, a depth gage, an arm carrying the latter and being adapted to be vertically ad justed on said frame, a divided shoe adjacent to said depth gage connectible with said frame, means for vertically and longitudinally adjusting the sections of said shoe on said frame, and a horizontally arranged roller projecting laterally from said shoe.
