Referring now to the drawings, 15 represents a bed plate or base of rectangular shape which has, at the opposite ends, legs 16 with suction cup feet 17 so that the same can be rigidly secured to a table or floor surface. On one end of this plate 15 is an upstanding motor mounting block 18 with a semicylindrical groove H therein for supporting an electric motor 20. This electric motor is held in place in the groove 19 and upon the bed plate 15 by two top plates 21 and 22 that are removably bolted to the bed plate by fastening screws 23 and 24 and nuts 24', FIG. 8. The electric motor 20 has a spindle shaft 25 with a transverse pin hole 26. The electric motor will be supplied with current in the usual manner by an electric cable cord and a plug by which said cord is attached to a wall receptacle, both not shown. The bed plate has series of adjusting peg holes 27 at the opposite end thereof by which a combined tailstock and saw table rest 28 is fixed to the bed plate. This tailstock has two pins 29 adapted to fit any two adjusting holes 27. This tailstock has an adjustable tight fitted center shaft 30 with a lathe dead center 31 revolvable thereon. Several rows of adjusting holes 32 are arranged to receive a combined lathe tool rest and circular saw ripping guide fence 33 having leg pin projections 34 adapted to enter the holes 32.
A saw table 35 is adapted to be detachably supported upon motor mounting block 18 and plates 21 and 22 and upon the combined tailstock and saw table rest 28. The saw table 35 is cut out on the motor end at 36 to receive the motor and projections 37 and 33 respectively extend along the opposite sides of the motor and are held in place on the heads of the fastening screws 23 and 24 fitting respectively into openings 39 and 40 in the projections 37 and 38.. At the opposite end of the saw table 35 are holes 41 and 42 for respectively receiving pins 43 and 44 projecting from the top of the combined tailstock and saw table rest 23. In this manner, the saw table is tightly held and supported on the motor mounting block assembly and combined tailstock and rest 28. Accordingly, there has been provided an arrangement in which the saw table is supported between a motor mounting and a tailstock.
A combined spindle and sander 45 is permanently fixed to the drive shaft 25 of the electric motor by a pin 46 that is extended through a hole 47 in the spindle and the hole 26 in the shaft 25. The outer end of the spindle 45 has a center hole 48 and a threaded offset drive hole 49 to provide means by which the various cutting tools are attached to the spindle to be driven thereby. The spindle has a pry slot 50 for the insertion of a screw driver or similar tool to pry a plate or other part from the spindle. Each of the cutting tools, face plates and live center have cooperating center and offset pins to establish the drive connection of the tool or center with the respective holes 48 and 49 of the spindle.
A circular saw 51 formed of soft plastic with set teeth 52 has a thick hub portion 53 to accommodate a center pin 54 and an offset pin 55 that can be tightly fitted into the center and offset holes-48 and 49 in the spindle 45, FIG. 1. A steadying pin 56 extends from the opposite direction of the saw 51 and can be supported on lathe dead center 31 of the tailstock 28 as best shown in FIG. 2. The circular saw 51 when so mounted projects upwardly through elongated slot 57 in the saw table and as the work piece is slid over the saw table and into engagement with the saw 51 it will be sawed. The combined tool rest and circular saw ripping fence 33 has base pin projections 58 which can be aidjustably fixed in adjusting holes 59 running along the front and rear sides of the saw table 35.
In order to cut pieces at an angle, there is provided a guideway 61 in which a cross slide 62 is adjustable. This cross slide has an angle guide 63 pivoted thereon by an upstanding pin 64 and which can be adjusted to the desired angle about the pivot pin 64 and fixed thereat by a wing nut 65. By placing the work piece against the straight edge 66 of the angle member 64 and moving the slide an angle cross cut is made on the end of the work piece by the saw. Because of the plastic foam being of soft polystyrene material, it easily is penetrated by the soft teeth of the plastic saw 51 and there is no chance of the child being injured during the saw cutting operation. The saw blade is resilient and will bear away from the finger, hand or arm that may come against it during the saw cutting operation.
In order to convert the toy for a jig saw cutting operation, the circular saw 51 is removed. A jig saw arbor 68 having a dovetail bottom plate 69 is slide fitted into a dovetail guideway 70 provided on the underside of the saw table 35 beneath the slot 57 and is held against displacement therefrom by a thumb screw 69. The upper end of the arbor extends beyond the bottom plate 69 and is bifurcated as indicated at 71 to receive the upper end of a jig saw blade 72 made of soft plastic with set teeth and slidably connected to the upper end 71 of the arbor 68 by a guide pin 73. The blade 72 is slidable relative to the upper end 71 of the arbor 68 and the pin 73 extends through a vertically-extending elongated slot 74 therein. The lower end of the blade 72 has a hole 75 and can be connected to the spindle by a set screw 76 extending therethrough and into the threaded offset hole 49 on the spindle 45. By rotation of the spindle 45 the blade 72 will be vertically worked against any work piece brought into engagement with its teeth. Various different cuts can be effected upon the work material with this jig saw. The angle guide 64 and the fence 33 can be used while effecting a jig saw cutting operation. Upon the saw table 35 being removed various turning, sanding, and drilling operations can be performed.
In FIGS. 4 and 10, a face plate 78 is secured to the end of the spindle 45. This face plate has a center pin 79 and an offset drive pin 80 which are fitted respectively into the holes 48 and 49 of the spindle 45. This face plate 78 also has outwardly inclined struck projections 81 over which a work piece W can be forced by a slight twist of the piece onto the projections 81. A pin 82 extends outwardly from the center of the plate 78 to steady the workpiece thereon. There is shown in FIG. 10, the lathe tool rest 33 positioned to extend across the bed plate from front to rear by extending the pin projections 34 into the holes 32 in the bed plate 15. The motor shaft will directly drive the spindle 45 and the face plate 78 and by resting a chisel tool C, FIG. 13, on the tool rest 33 work piece W will be shaped in the usual manner.
If a disc sanding operation is desired, a sanding disc '83 with sand paper 84 on the face thereof will be secured to the spindle 45, FIGS. 1, 5 and 7. This sanding disc 83 has a thickened hub portion 85 from which center and offset pins 86 and 87 extend respectively into the end holes 48 and 49 of the spindle 45. The tool rest 33 is disposed across the bed plate 15 as shown in FIG. 7 to do flat sanding.
A spindle sanding operation can be effected with the spindle 45 as it is coated with sanding material 45' by freeing the same of the other tools to render it accessible as shown in FIG. 8.
If a center turning operation is desired a lathe live center 88 is secured to the spindle 45 by its center and offset pins 89 and 90. This live center has diametrically spaced pins 91 and 92 for engaging with the end of the work piece as best shown in FIGS. 6 and 11 for the purpose of center turning work piece W, FIG. 11, which is centered on the revolving dead center 31. The combined tool rest and ripping fence 33 is fixed by its pins 34 to the front of the bed plate 15 and is adapted to support a cutting chisel C, FIG. 13, used for rough finishing of the work piece. Thereafter, a template 93 can be thrust forward toward the work piece W as shown in FIG. 11 to effect the final cut from the Work piece W. The plastic foam being an easily workable material permits cutting over a long length by the inward thrust of the template 93 which has stop shoulders 93. This template 93 is guided by guide members 94 and 95 adjusted to holes 33 in the tool rest 33 as seen in FIG. 12 and numbered to the different size templates. If it is desired to do a drilling operation a wood or plastic drill 96 is connected by its shank 97 in tight fitting engagement with the center hole 48 of the spindle 45 as best shown in FIGS. 1 and 9.
It should be apparent that there has been provided a convertible wood-type machine shop toy adapted for use particularly with a soft working medium such as plastic foam and with which all of the usual wood type working operations of circular saw cutting, jig saw cutting, face plate turning, center turning drilling, disc sanding and spindle sanding can be effected.
It will also be apparent that these parts are assembled in a unique and different way to make for simplicity of the arrangement and at the same time one in which all operations are performed in the same manner as a regular wood working machine tool and where the tools are of soft resilient plastic so that injury to the child, even though the tool is power driven, cannot occur.
