Referring now particularly to FIGS. 1 to 5, there is shown generally an electric motor-driven spindle head 15 which can be either stood upright as shown in FIG. 1 or turned down on its side as shown in FIG. 3 and to which when stood upright a guide rod 16 is attached and along which a tailstock 17 is adjustable and which with the headstock may support a saw table plate 18 with a jig saw arm 19.

The spindle head 15 has two spaced

side plates

21 and 22 held apart by an electric motor assembly 23 disposed between them and from which a spindle 24 extends. This spindle is serrated on its cylindrical surface as indicated at 24' and is fixed to a drive shaft 25 that extends through a slot 26 depending from the upper edge of the side plate 22. The lower edges of the

plates

21 and 22 are shaped to provide

foot portions

27 and 28 respectively. The motor assembly 23 may contain batteries to power the motor or the motor may be powered from a wall cord. The motor assembly 23 and the side plates have ventilating holes 29.

Extending through the corners of the

side plates

21 and 22 are spacing rods 30 that extend from the plate 21 to provide leg portions 31 and from the plate 22 to provide saw table support portions 32. The support portions 32 are shouldered and have reduced end portions 33 adapted to extend into holes 34 of the saw table plate J 18 to hold the same. These leg and supporting

portions

31 and 32 of the rods 30 are made use of, when the motor spindle head 15 is turned down on its sideplate 21 as shown in FIG. 3, the tailstock 17 and the guide rod 16 having been removed from an opening 35 in a triangularshaped sleeve bracket 36 extending outwardly from the plate 22 and a triangular-shaped opening 37 in the side plate 21 aligned with the bracket sleeve opening 35. A hand set screw 38 is first loosened from the bracket 36 to release the guide rod 16 and tightened to holdit.

The guide rod 16 is of triangular section and slidably receives the tailstock 17 that has a corresponding opening 39'therefor. The tailstock has foot portions 17 on level with the

foot portions

27 and 28 of the spindle head 15 for engaging a table surface and a thumb screw 41 for fixing the tailstock to the rod 16 in its adjusted position thereon.

When the toy is to be used for a turning operation a live center drive plate 42 is fixed to the spindle 24 by a thumb bolt 43 extending through a center hole 42 in the plate 42 and into a threaded center hole 44 in the end of the drive spindle 24. The live spindle plate 42 has three prongs 45 to which the polystyrene or foam plastic work piece material is fixed. A dead tailstock spindle point 46 receives the opposite end of the work piece.

When the toy is being used for a lathe operation, the

toy with the work piece extended between the spindle plate 42 and tailstock point 46 is placed in the toy box and the edges of the box for supporting a cutting chisel made of wood or plastic and the work chips drop and are contained in the box.

When it is desired to effect a saw cutting operation a flexible plastic saw disk 51 is secured to the drive spindle 24 by the thumb screw 43 extending through a center hole 52 of the saw disk and into the threaded hole 44 of the drive spindle, FIGS. 1 and 5. The saw table plate 18 is placed over the motor driven spindle head 15 so that its upstanding spaced

pins

53 and 54 respectively extend into a hole 34 and an intermediate hole 56 of the saw plate 18. The tailstock 17 is drawn to a position upon the guide rod 16 so that its upwardly projecting pin 57 extends through an intermediate hole 58 on the opposite edge of the saw table plate 18. The saw table 16 has an elongated slot 59 and the saw disk 51 extends upwardly as shown in FIG. so that upon placing a work piece W on the surface of the saw table 18 and against the saw disk 51 a saw disk cutting operation is effected upon the work piece.

If it is desired to operate a face grinder 61 it can be similarly fixed to the spindle 24 by the thumb screw 43 extended through a center hole 62 thereof and into the threaded hole 44 of the spindle 24. A work piece W can be held against the outer face of the grinder disk 61 or against its periphery. A grinding or sanding operation can be also provided by the spindle 24 from its parallel serrations 24' on the periphery thereof. The saw table plate 18 is removed when these grinding operations are being effected.

If a jig saw operation is desired the saw table plate 18 is supported upon the motor head andthe tailstock 17 as with the disk saw cutting operation, FIGS. 1 and 4. A.

jig saw blade 63 is extended through the elongated saw slot 59 and connected by a removable threaded crank pin 64 extending through a hole 65 in the lower end of the saw blade and into a threaded offset hole 66 in the end of the spindle 24 so that upon rotation of the spindle 24 the saw blade 63 is worked up and down through the saw slot 59 in the saw table plate 18. The upper end of the saw blade 63 is bifurcated to provide a slot 67 that receives a pin 68 on the forward end of the arm 19 and to hold the blade 63 against outward displacement from an end slot 69 in the arm 19 while permitting vertical reciprocal movement of the blade 63.

The arm 19 has a bottom forwardly-extending portion 71 with a transverse slot '72 with an inclined rear wall 73 that will support the arbor against downward displacement from the transverse portion 74 of the table while permitting an upstanding projection 75 to extend into the rear end of the elongated saw slot 59 and thereby hold the arm against lateral displacement and the forward upper end of the arm maintained in proper vertical alignment with the saw slot 59 to keep the jig saw blade 63 centered therein. With the motor 23 running and a work piece placed upon the table against the jig saw blade 63 a jig saw cutting operation is elfected.

When it is desired to use the toy for a routing operation, the thumb screw 38 is loosened and the guide rod 16 and tailstock 17 are removed from the sleeve bracket 36 and the spindle head 15. The motor-driven spindle head is turned down upon its leg portions 31, the arm 19 and the saw blade 63 having been removed from the table saw plate 18. The table saw plate is turned ninety degrees and its corner holes 34 fitted over the reduced diameter ends 33 of the support portions 32 in the manner shown in FIG. 3. A router or sabre bit 76 is threaded into the center hole 44 of the spindle 24 of the motor and will extend upwardly through the elongated saw slot 59 and against which a work piece lying on the saw table surface can be brought to bear to effect a routing operation thereupon.

Referring now to FIGS. 6 to 9, there is shown a modified form of the invention in which a head stock 80 is provided with an electric motor drive battery unit 81 mounted between

upright side portions

82 and 83 on

opposing thumb screws

84 and 85 extending respectively into the ends of the motor battery unit 81 and on which the unit 81 can be pivoted upwardly to a position best illustrated in FIG. 8 so that a routing bit 86 can be used. The

side portions

82 and 83 extend upwardly from a base portion 87 and they respectively have

open slots

88 and 89 for holding the

respective thumb screws

84 and 85 whereby the motor unit 81 upon loosening the thumb screws can easily be lifted from the side portions. This motor drive unit 81 has a spindle 91 with a threaded central hole 92 to receive the routing bit 86 or a thumb screw 93 adapted to respectively retain on the spindle 91 either a lathelive center plate 94 or a disk saw 95 or a grinder '96 to be driven thereby.

Parallel guide rods

97 and 98 extend from the head base portion 87 to provide a tool bed and which are held in spaced relation at their outer ends by an end support member 99. Slidable along the

guide rods

97 and 98 is a tailstock 101 which is retained on the guide rods in its adjusted position by a thumb screw 102. This tailstock 101 has a dead center pin 103 which supports the outer end of the work piece while the drive end of the work piece is connected to the live center plate 94 through its pins 104. This plate 92 is connected by the thumb screw 93 to the spindle 91. The spindle 91 has serrations 105to effect a grinding or sanding operation.

The tailstock 1011 has anupstanding pin 106 that will extend into a hole 107 in a saw table plate 108 when the tailstock is adjusted to a position measured from two upstanding pins 109 and 111 on the respective

upright portions

82 and 83 of the spindle head 80 and these pins extend respectively into holes 112 and 113 on the 0pposite end of the saw table plate 108; The router or sabre bit 86 will extend through a hole 114 in the plate 108; FIGS. 6 and 8.

The saw table plate 108 has an elongated slot 116 through which the disk saw 95 extends on being secured to the spindle 91 by the thumb screw 93. A work piece will be slid upon the saw table surface to engage the saw 95 and effect a cuttingoperation thereon. This saw disc is made of soft plastic and can fiex and upon engaging the fingers of the child will effect no harm to them, yet upon working with the foam plastic material a true cutting of the material can be effected.

When it is desired to effect a jig saw cutting operation a vertical saw blade 117 is secured at its lower end by a thumb screw 118 that passes through a hole 119 in the lower end of the blade and into a threaded offset hole 121 in the spindle '91 so that reciprocation of the blade 117 by crank action is effected on rotation of the spindle 91.

To support the jig saw blade 117 at its upper end for reciprocation an arm 122 is connected to the rear edge of the saw table plate 108 by a dovetail projection 123 that extends into a dovetail groove 124. The arm 122 has a slot 126 into which the saw blade 117 extends and the saw blade has a slot 127 through which a pin 128 extends to retain the saw blade in the arm slot 126 and over which the saw blade 117 can slide and be retained thereby against forward outward displacement therefrom.

Referring now particularly to FIGS. to 12, there is shown the still further modification of the invention in which the battery is contained along the bed of the toy. This toy includes a motor-driven head stock 131 that has a top housing i132 and in which is contained an electric motor 133 that drives a spindle 134 to which a saw disk 136, a grinder wheel 137 can be attached by a thumb screw 138 extended into a threaded center hole 139 thereof. A drill 141, a router 142 or a live center 143 can likewise be attached to the live spindle 134 by threading their respective shanks into the threaded center hole 139.

Extended outwardly from the spindle head 131 is a battery casing 144 into which battery cells can be extended by removal of an end cap 145. Electric circuit is provided between the batteries, the motor :133 and a switch arm 146 that can pivot on the side of the spindle head 131 on a pin 1'47 and which can engage a fixed contact 148 to close the circuit and cause the rotation of the motor 133 and the spindle drive 134.

On the outer end of the battery case 144 is mounted an end support 149 which is connected to the head stock 131 by

guide rods

151 and 152. On these guide rods 151 and 152 a tailstock 153 may be adjusted and fixed in its adjusted position by a thumb screw 154. This tailstock has a dead center pin 169 adapted to support a work piece when the work piece is being driven by the live center 143.

When the disk saw 136 is secured to the spindle 134 by the thumb screw 138 as best shown in FIG. 12, the disk saw will extend upwardly through a slot 157 in a saw table 158 that is dished on its underside and is supported from brackets .161 and 16-2 extending upwardly from the head 131 which have outwardly bent ends 163 and 164 and which respectively extend through

elongated slots

165 and 166 in the saw table 158 to support one edge thereof while the opposite edge thereof has its depending flange notched at 167 to receive the upper end of the tailstock-153 which has a groove 168 in which the flange will rest and by this connection of the flange with the slot 168, the saw table is held against lateral displacement. The tailstock 153 will in turn, of course, be locked by the thumb screw 154 to the rod 151. The tailstock has a point 169 cEor supporting a lathe work piece.

When it is desired to set up the toy for a jig saw operation a jig saw blade v17-1 is fixed by a screw 172 to an offset threaded hole 173 in the end of the motor driven spindle 134. This saw blade 171 is extended upwardly through the slot 157 in the saw table plate 158 and is slidable in the end of an arm 174 that has a base attaching plate 175 that is projected through a slot 176 in the flange at the rear of the plate and over

hanger flanges

177 and 178 struck downwardly from the sides of the saw slot 157 and bent inwardly to support the reduced Width end 179 of the arm base plate 175.

The upper end of the saw blade has an open slot 181 through which a pin 183 on the arm 174 extends to hold the blade in an end slot 183 of the arm and against outward displacement therefrom while allowing the blade to be worked up and down therethrough. By virtue of the crank action of the rotating spindle 134 upon the crank pin 172 and the blade 171, the saw blade is vertically reciprccated so that while presenting a work piece to the saw blade a jig saw cutting operation will be performed thereupon.

With this last form of the invention batteries can be provided in the battery case 144 and the motor driven thereby while the other forms of the invention and any other means can be provided such as a cable cord to supply electric current to the motor from an electric outlet receptacle by simply making a plug connection therewith.

It should now be apparent that there has been provided a wood working machine shop toy which can be converted from a lathe to effect various saw machine cutting operations, a routing and drilling operation. It will also be apparent that the head stocks which contain the motor according to two forms of the invention can either be detached from the tailstock guide rods and turned over on its side and support the saw table in that position, or according to the second form of the invention the electric motor can be pivoted on the head stock and a router for sabre bit extended upwardly through a separate hole in the saw table plate.
