Application filed May 25,

:This invention relates to woodworking machines and particularly to machines rendered'convertible to adapt them to use for various machining operations. 7

It :is the object of the invention .to provide a machine of thischaracter in which the power transmitting means comprising a driving motor and a driven mandrel are. combined in a unitary mounting pivotally supported upon the frame of the machine and connected with controlling means by which said mounting maybe tiltedbodily .to establish said mandrel in angular driven positions relative to said frame, a further provision being made for effecting adjustment of the mandrel longitudinally upon the mounting in .a certain established posi- .tion of the latter. 7 V n A preferred embodiment of the invention I is [illustrated in the accompanying drawings, wherein,' Fig. 1 is an end elevation of the machine.

Fig. 2 is a side elevation showing the .parts .as in the position of Fig. 1.; in which the mandrel is in a horizontal plane for use .as a saw arbor or the like.

' Fig. 3fis also a :side elevation showing the power transmitting unit tilted with the mandrel in a vertical position to serve as the spindle of a shaper.

In these views the reference character 1 designates the legs of a frame connected uponopposite sides by upper and. lower transverse rails '2 and .3 respectively, cross rails 4 at opposite ends and an intermediate cross rail 5 connecting thelower side rails 3 the parts being preferably formed integral. Journal bearing boxes 6 are secured by bolts 7 upon the side rails .2 intermediate the ends of the frame and mounted upon trunnions .8 journaled in said bearings is a platform 9 adapted to tilt or rock thereon through a range of 90 degrees, movement being imparted to tilt and to some extent retain said platform in angular positions of adjustment by "means of a worm wheel 10 fixed upon a trunnion 8 and meshing with a-worm shaft 11 journaled in .a bearing bracket 12 secured by bolts 13 to a side rail 2. of the frame, said worm shaft having a 1923. Serial No. 641.356.

hand wheel 14. by which a may be rotated.

, An electric motor '15 havinga pulley 16 is secured at its base by bolts 17 to the under face of the platform 9 to swing in unison therewith, and extending concentric 55 with the "pivotal axis of said platform in spaced relation to the under face of said motor is an areuate brace 18 engaged 'at its upper end with a leg 1 and secured at .its lower end by bolts 19 With'the rail 50f the frame. Said brace has a radial slot '20 receiving the stem of aboss 21 bolted to the motor and having screwfthreaded engagement withv a hand Wheel '22 by means of which said motor may be clamped to said brace in any tilted position of the platform.

Formed in the upper -face of said platform is a transverse way or groove 23' hav ing undercut edges for the reception .of the correspondingly shaped base 24 of -a yoke shaped journal bracket 25 adapted to slide longitudinally therein. Movement of said bracketiscontrolled by a screw shaft 26 journaled at opposite ends in bearings .27 integral with said platform and having screw threaded engagement intermediate said. bearings with a lug 28 projecting laterally from the bracket 25. Said shaft is held againstaxial movement in its bearings by collars 29 and has fixed upon one end thereof a beveled gear 30 adapted to mesh with a beveled gear 31' in the tilted position of the platform as-shown in Fig. 3. Thegear 31 is mounted upon a horizontal shaft 32 which is journaled at one end in a bearing extension 33 on the rails .2 of the frame and at its opposite end said shaft is ,journaled in a bearing 34 on a leg 1 of the frame and carries .a hand wheel 35 by which it may be rotated to transmit rotation to the screw 26 and impart movement to the bracket 25 longitudinally thereof.

The extremities of the bracket .25 are pro vided with bearing boxes 36 in which a shaft 37 is .journaled adjacent its ends and which 5 is retained against axial movement by thrust collars 38 engaging said bearings. One end 39 of said shaft projects beyond saidbracket and is adapted to serve as a saw arbor in' the horizontal position as 00 and as a shaper OSIt IOD of Fig. 3, i the re engaged at its upper end with a stationary table l-l mounted on said frame. Said brace has a transverse slot 4-5 concentric with the axis of the platform 9, terminating in a vertical extension 4:6 at the lower end thereof, and extending through said slot from a lateral boss 1-? on the bracket 25 is a screw threaded stem 48 engaged by a hand wheel 49 by which saidbracket may be clamped to said brace in tilted positions of said platform, the vertical slot 46 bein adapted to accommodate axial adjustment of the shaft 3? in the vertical position of thebracket, as in Fig. 3.

Supported upon laterally extending inclined brackets 50, integral with the bear ings 6, are like sections 51 of a centrally divided table the sections of which are similarly mounted upon adjustable wedges 52 engaged by the screws of hand wheels 58 journaled in said brackets and by means of which said sections may be adjusted "elative to the cutter head 40.

' A tiltable table 54: is supported above the spindle 39 upon spaced rocker brackets 55 ngaged with the upper ends of the legs 1, each having an arcuate slot 56 receiving a stud 57 anchored in the leg and screwthrcaded engagement ith a hand wheel 58 for clamping said brackets to said legs. T he periphery of one of said brackets is formed with worm gear teeth 59 in mesh with a worm shaft 60 journa -led in a leg 1 and having a hand wheel 61 for rotating said shaft to impart a rocking movementto said brackets and effect a tilting of said table.

it will now be understood that with the parts in the position of Figs. 1 and 2 the driven shaft 37 is so disposed as to enable the cutter head 40 to be used in connection with the table sections 51 for planing and jointing purposes, while the spindle 39 may be employed with the tiltable table 54L for various sawing operations. By releasing the hand'wheels 22 and d9 from binding enent with their respective braces and havingsegarated the table sections 51 and tilted the table 54; sufficiently to provide clearance for passage of the spindle 39, the hand wheel 14 may be rotated to turn the gear and swing the platform 9 with the of said support.

motor and driven shaft 37 to the vertical position of Fig. 3. In this position the gear will mesh with the gear 31, and the stem d8 of the bracket 25 will have passed into the slot 46 of the brace 43, so that upon rotating the hand wheel motion will be transmitted through said gears to turn the wormshaft 26 through which movement will be imparted to vertically adjust the bracket 25 and establish the shaft 37 in the desired axial relation to the table l4 to enable the spindle 39 who employed for shaping operations. 7
