signors to Mattel, Inc., Hawthorne, Calif., a corporation of California Filed Jan. 4, 1%5, Ser. No. 423,241 14 Claims. (Cl. 144-1) This invention relates to a new and useful toy machine shop tool and more particularly to a toy, motordriven, convertible wood-working type machine shop tool.

Toy, motor-driven, convertible wood-working type machine shop tools are available. While generally satisfactory, these prior art toys do have certain disadvantages.

One disadvantage resides in the fact that certain of these prior art toys employ simulated saws, drills and the like which are incapable of performing actual wood-working operations with the result that a child soon becomes bored with them.

Although certain other prior art toys of this type employ saws, drills and the like which are capable of performing wood-working operations, they have the disadvantage that the average child experiences diiculty in setting up the toy for a particular operation and in operating the toy to turn out a finished product having a desired form.

In view of the foregoing factors and conditions characteristic of toy machine shop tools, it is a primary object of the present invention to provide a new and useful toy machine shop tool of the wood-working type not subject to the disadvantages enumerated above and having tool-holder means adapted to cooperate with template `means for minimizing the skill required to perform wood-working operations and accurately reproduce objects such as table legs with the machine efficiently, safely and expeditiously.

Another object of the present invention a toy, motor-driven, convertible chine shop tool.

Yet another object of the vide a new and useful described.

Still another object of the present invention is to provide a new and improved holder for a toy, lathe tool-bit which co-acts with a template of the present invention to guide the tool-bit during wood-working operations.

A further object of the present invention is to provide a new and useful live center for a toy lathe.

A still further object of the present invention is to provide a toy of the type described which may be converted from a lathe to a drill press by a child safely, eiiciently and expeditiously.

Another object of the present invention is to provide a new and useful toy jig saw.

Yet another object of the present invention is to provide a new and useful toy bench saw. i

Another object of the present invention is to provide a new and useful toy table sander.

According to a rst embodiment of the present invention, a toy, motor driven, convertible wood-working type machine shop tool is provided which comprises a motor driven head-stock, a bed plate and a tail-stock. A safety handle is provided which can be slidably mounted on the bed and used as a tool holder for ya lathe toolbit when the toy is used as a lathe. When so` used, a feeler is attached to the safety handle Where it co-acts with a template mounted on the bed to guide the tool during wood-working operations.

is to provide wood-working type mapresent invention is to prosafety handle for a toy of the type The lathe can be converted to a jig saw by rotating the head-stock, bed plate and tail-stock assembly degrees so that the bed is upper most. The safety handle is then attached to the bed in such a manner that it serves as an arm for supporting a leaf spring. A jig saw blade -may then be connected to the spring and to a sliding block on the head-stock which reciprocates the blade.

The head-stock is slidably mounted on ways on the bed and may be either locked to the ways for certain 0perations or left free to be slid along the ways when the head-stock is used as a drill press. When so used, the safety handle is attached to the head-stock to move it into engagement with the Work being drilled.

A circular saw and a sanding head are `also provided. These tools may be driven by the head-stock when the bed is in its upper most position. The bed includes an opening through which the sanding disc and the circular saw extend in such a manner that the bed serves `as a work supporting table.

According to a second embodiment of the present invention, a motor driven head-stock, a bed plate and a tail-stock are provided. The head-stock is slidably mounted on the bed plate and is spring-loaded against stops at one end thereof by suitable spring means. The tail-stock is removably mounted on the other end of the bed plate and is adapted to be connected to the headstock for use as a table when the device is used as a circular saw, a jig saw or a sanding machine.

A safetyV handle similar to that used with the first embodiments is also provided for use in the manner mentioned above in connection with the first embodiment. In addition, the feeler of the second embodiment may also be used as a fence for sawing operations.

The tail stock is provided with suitable legs which may be used to support the bed plate and head-stock vertically for drill press operations. During such operations, the safety handle is connected to the head-stock for moving it downwardly into engagement with a work piece against the bias of the spring means which minimizes the force required to return the head-stock to its elevated position.

An important feature of the second embodiment of the present invention resides in a live-center which may be used in combination with the tail stock to compensate for misalignment of a work piece during lathe operations.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in connection with the accompanying drawings in which like reference characters refer to like elements in the several Views.

Referring again to the drawings and particularly FIG- URES 1-4, a toy, motor-driven, convertible, wood-working type machine shop tool, generally designated 10, includes a bed 12, a motor-driven, slida-bie head-stock 14 and a xed tail stock 16.

The bed 12 may be made from any suitable material such as plastic, sheet steel or extruded aluminum and includes a bottom wall 18 and a pair of T-shaped, upstanding, parallel, spaced-

apart ways

20 and 21 which are engageable 'at the will of the operator of the toy 10 by a first pair of grooves or slots 22 provided at the lower end 24 of the head-stock 14 or by a second pair of slots or grooves 26 provided at the upper end 28 thereof. The

ways

20 and 21 are also engaged by grooves 29 provided in tail-stock 16 which is aixed to the bed 12 by screws 29a. The head-stock 14 is reciprocally mounted on the ways 20 yand 21 and is biased to the left, as viewed in FIGURE 2, by a compression spring 30 which encompasses a rod 32 having one end 34 secured in the tail-stock 16 and on other end 36 slidably engaged by the head-stock 14. The spring 30 minimizes the effort required to accurately position the head-stock 14, and facilitates employing the toy 10 as a drill press, 'as will be hereinafter described.

The head-stock 14 may be locked to the bed 12 by a locking device 38 including a block 40 which is slidably mounted in the head-stock 14. The block 40 includes an elongated slot 42 through which an eccentric 44 extends. The eccentric 44 is rotatably mounted in the head-stock 14 and may be rotated by an over-throw lever 46. When lrot-ated in a clockwise direction, as viewed in FIGURE 2, the eccentric 44 forces the block 40 downwardly into engagement with the way 20. This securely locks the head-stock 14 to the bed 12 at any point along the ways 20and 21.

T he toy 10` is shown in FIGURES 1-4 in a form suitable for `operation as a lathe. The toy 10 is prepared for operation as a lathe by rotatably mounting a tail-stock bearing 48 in an aperture 50 provided in the tail-s-tock 16. The tail-stock bearing 48 includes a cylindrical =body portion 52 having an annular shoulder 54 formed at one end 56 thereof. The tail-stock bearing 48 may be made from a suitable bearing material such as brass or from a plastic material having a low coeicient friction and is provided wi-th a counter bore or cavity 58 at its end 56. A pin 60 is mounted in the cavity 58 at right angles to the major axis thereof, and is engageable by the bifurcated end 62 of a live center 64.

The live center 64 includes a wood screw 66 so that it can be screwed into a sui-table work piece 68 made of wood, plastic or the like. The bifurcated end 62 is an important feature of the invention because it permits swingably mounting the live center 64 on the pin 60 to minimize the effect when the live center 64 is not placed in the exact center of the longitudinal axis of the work piece 68.

When used as a lathe, the toy 10 also includes a live center 70 having a wood screw 72 which is engageable with the work piece 68 and a bifurcated end 74 which is engageable with a pin 76 iixedly mounted cross-wise in a bore 78 provided in a lathe drive 80. The lathe drive 80 includes an enlarged face plate 82 to which a sanding disc 83 may be aiiixed in a manner to be hereinafter described. The lathe drive also includes a hub 84 having a noncylindrical bore or cavity 86 engageable with non-cylindrical, motor output-shaft 88 provided on a motor 90' in the head-stock 14. The hub 84 engages a at face 91 on Ithe shaft 88 with a suitable friction fit so that the lathe drive 80 will be driven by the shaft 88. The motor 90 is cooled by a fan 90a, as more fully shown in FIGURE 13, and is supplied with power through electrical leads 92 and a suitable switch 94.

The toy 10 also includes a safety handle 96 having a C-shaped grip portion 98. A channel-shaped cross bar is aflxed to one end 102 of the grip 98 and a tool holder 104 is affixed to the other end 106 of the grip 98. When the device 10 is to be operated as a lathe, a lathe tool-bit 108 is retained in position on the tool holder 104 by a thumb screw 110. The skill required to manipulate the tool 108 in wood-working operations is minimized by employing a template 112 which may be mounted in a suitable slot 114 provided on the way 21. The template 112 is provided with a suitable design 116 on its upper edge 117 forming a pattern which may -be followed by the tool 108 to reproduce the design 116 on the work piece 68. The tool 108 is caused to follow the design 116 by a probe or feeler 120` having one end 122 affixed to the cross-arm or bar 100 and its other end 124 engageable with the pattern 116 when the bar 100 is in engagement with the way 20. The handle 96 is rockably and slidably mounted on the way 20 by a ridge 126 and lips 128 provided on the channel-shaped bar 100. The feeler 120 co-acts with the template 112 to control the depth of cut obtainable with the tool bit 108 in such a manner that the pattern 116 is reproduced on the work piece 68, as shown in FIGURE 2.

The toy or device 10 may be readily converted from the lathe shown in FIGURES 1-4 -to a drill press by removing the tail stock bearing 48, the lathe drive 80, the lathe bit 108, the probe 120 and the template 112 after which the locking mechanism 38 may be released so that the head stock 14 is free to reciprocate on the bed 12.

Referring now to FIGURES 5-7, after the aforementioned parts have been removed and the locking mechanism 38 has been released, the bar 100 is inserted into a clamp or saddle which is axed to the head-stock 14. The bar 100 is retained in position in the saddle 130 by a suitable thumb screw 132 after which the handle may be employed to move the head-stock 14 toward the tail-stock 16 against the pressure exetred by spring 30 (FIGURE 2) until a drill blade 134 engages a work piece 136 positioned on the bed plate 12 against the tail-stock 16. The drill 134 isf aligned with the aperture 50 so that the drill may pass through the tail-stock 16 after drilling a hole in the work piece 136. The drill 134 may be conveniently stamped from a suitable piece of sheet steel and includes a body portion 138 having a flat, depressed portion 140 engageable with the hat face 91 on the shaft 88 for rotation of the drill bit 134 thereby. The drill 134 is also provided with a semi-cylindrical strap member 144 which encompasses the semi-cylindrical portion 146 of the shaft 88. The drill 134 also includes a blade portion 148 which is provided with a sharpened tip 150 adapted to drill a hole in the work piece 136 when the blade 134 is rotated by motor 90. Of course it will be apparent to those skilled in the art that the toy may also be used vertically as a drill press with the head-stock 14 uppermost and the tail-stock 16 serving as a base.

Referring now to FIGURES 8 and 1l, the toy 10 may be readily converted to a bench sander or table saw by removing the head stock 14 from the bed 12 and turning it over so that the grooves 26 engage the

ways

20 and 21. The head stock 14 is slid to the end 152 of bed 12 which is remote from thetail stock 16 and then secured in position by actuating the locking mechanism 38. This operation positions the motor shaft 88 adjacent a slot 154 which is provided in the bottom Wall 18 and through which the face plate 82 of the lathe drive 80 extends when the hub 84 engages the shaft 88. The toy 10 is then inverted so that the bottom wall 18 of bed 12 becomes a table on which a work piece can be supported. In this position, the device 10 may be supported on a suitable surface by the top walls 141: and 16h of head stock 14 and tail stock 16, respectively. The tail stock 16 and the head stock 14 are of equal height so the bed 18 will be level in its inverted position.

Alternatively, a circular saw 158 having a cylindrical hub 159, which is provided with a non-cylindrical bore 161 adapted to frictionally engage the shaft 88, may be substituted for the lathe drive 80 when it is desired to use the device 10 as a circular or table saw. Danger to a child operating the device 10 as a table saw may be minimized by providing the circular saw 158 in the form of an anti-kick up blade or a plaster cast cutter of types which are well known in the art. One such plaster cast cutter which may be used satisfactorily is that shown in Stryker Patent No. 2,427,580.

Referring now to FIGURES 9 and 10, the device 10 may be readily converted for operation as a jig saw by mounting the head stock 14 on the bed 12 in its FIGURE 1 position so that the grooves 22 engage the

ways

20 and 21. The device 10 is then turned upside down from its FIGURE l position so that the bottom Wall 18 is again upper most. Also, the head stock 14 is positioned on the bed 12 in such a manner that `a reciprocating jig saw driving plate 160 is aligned with an aperture 162 provided near the end 152 of the bottom wall 18 (FIGURE 8). The locking mechanism 38 may then'be actuated to lock the head stock 14 to the bed 12.

The plate 160 is provided with an aperture 164 at one end 166 which is engageable by an eccentric member 168 aflixed to the motor shaft 88 for rotation thereby. Rotation of the eccentric 168 causes the plate 160 to reciprocate within suitable guide members 170 which are aixed to the front wall 176 of the head stock 14. A leaf spring 172 is afXed to the guides 170 in such a manner that a shoe 174 provided on the spring 172 bears against the plate 1,60 to maintain it in sliding contact with the front Wall 176 of the head stock 14. The plate 160 and the guides 170 may be conveniently made from a suitable plastic having a low coeicient of friction to minimize the force required to reciprocate the plate 160. The other end 176 of the plate 160 is provided With a saw-receiving block 178 which is engaged by a transverse pin 180 provided on one end 182 of a jig saw blade 184. The other end 186 of blade 184 also carries a transverse pin 188 which is engageable with the bifurcated end 190 of a leaf spring 192.

When the toy 10 is employed as a jig saw, the handle 96 serves as a support arm for the leaf spring l192 which may be connected to the handle 96 by inserting the end 194 of spring 192 into the tool holder 104 and retaining it in position by the thumb screw 110. The handle 96 is connected to the head-stock 14 by engaging the bar 100 in the saddle 130 and tightening the thumb screw 132. When the motor (FIGURE 2) is energized to rot-ate shaft 88, the eccentric 168 causes the plate 160 to reciprocate with a short stroke thereby reciprocating the blade 184.

A toy, motor-driven, convertible wood-Working type machine shop tool constituting a second embodiment of the present invention, generally designated 10a. is shown in FIGURES 12-20. The tool 10a is shown in FIG- URES 12-15 in the form of a lathe and includes, generally, a head-stock 14a, a tail-stock 16a, and a bed 12a. The head-stock 14a. includes an electric motor 90 having a shaft 88, both of which may be identical to the same elements shown in conection with the first embodiment of the present invention. The head-stock 14a is provided with grooves or slots 22u which engage

ways

20a and 21a to reciprocally mount the head-stock 14a on the bed 12a above its bottom wall 18a. The head-stock 14a also includes a housing 200 in which a spring 30a is coiled. The spring 30a has a first end 202 which is affixed to the hous- 14rz in positionV against stops 207 at the end 152e of the bed 12a.

The tail-stock 16a is also reciprocally mounted on the

ways

20a and 21a by a pair of grooves 29a and may be locked in position on the bed 12a by a locking mechanism 38@ having a hand wheel 46a affixed to a shaft 208 to which an eccentric member 210 is ail'ixed for rotation thereby (FIGURE 18). The eccentric 210 carrier a spider 212 having depending arms 214 which are engageable with the

ways

20a and 21a to lock the tail-stock 16a in position on the bed 12a. The tail-stock 16a also is provided with an aperture 50a which is adapted to rotat- 66b. The lathe drive 80 ofthe FIGURE 1 embodiment 88 when the tool 10a is to be used as a lathe. Also, a pair of live centers 64a may be used to connect a work piece 68a in position on the tool 10a. The live centers 64a are connected to the Work piece 68a by gouging holes in the ends thereof and inserting the uted ends 66a therein. One live center 64a is then placed in position on the lathe drive 80 whereupon the tail-stock 16a may be slid toward the head-stock 14a until the other live center 64a. engages the tail-stock aperture 50a. The locking mechanism 38a may then be actuated to lock the tail-stock 16a in position and a template 11251. may be mounted in a slot 114e on way 21a. The bulbous end 48a of the said one center 74a engages the aperture 78 with a friction lit for rotation by the drive 80. The bulbous end 48a of the other center 64a on the other hand, is rotatably mounted in aperture 50a and compensates for misalignment of the work piece 68a.

The tool 10a also includes a handle 96a having a rst end 102er which is provided with an extrusion 10061. The member e may be slidably and rockably attached to the bed 12a by engaging it in a slot 216 provided in the way 20a. The handle 96a also includes an end 106a to which a tool bit holder 104a is alixed by a bolt 218. A llathe tool-'bit 108 of the FIGURE 1 embodiment is secured in position on the tool holder 104:1 by a thumb screw e and `a probe 120a is attached to the end 10211 by a screw 220 for engagement with the template 112er.

The tool 10a may be converted from the lathe shown in FIGURE 13 to the bench sander shown in FIGURE 6 by removing the tail-stock 16a from bed 12a and ataching it to the head-stock 14a. For this purpose, the ail-stock 16a includes a depending flange 222 having a J-shaped opening 224 provided therein which is adapted o straddle the shaft 88. The tail-stock 16a also includes t depending lip portion 226 which is engageable behind in upstanding flange 228 provided on the head-stock 14a. With the tail-stock 16a in position as shown in FIGURE 16, the device a imay be employed as a bench sander by connecting the lathe drive 80 to the motor shaft 88 in such a manner that the face plate 82 extends through a slot 154a which is provided in the tail stock 16a. Of course, it is .apparent that the circular saw 158 in FIG- URE ll can be substituted for the lathe drive 80 and that the front wall 16C of tail-stock 16a and the top wall 14C of the head-stock 14a cooperate to form a table for supporting a suitable work piece.

, The tool 10a may be converted to a jig saw as shown in FIGURE 17 by engaging a slot 230, which is provided in the housing 200 of head-stock 14a, with the extrusion 100a provided on the handle 96a. The handle 96a then forms a jig saw fra-me wherein the tool holder 10411 extends above the head-stock 14a in such a manner that the leaf spring 192 previously described in connection with the tool 10 Imay be secured to the tool holder lll-4a by the thumb screw l10n. The bifurcated end 190 of the spring 192 then extends above a notch 232 which is provided in the tail-stock 16a (FIGURE 19). The head-stock 14a is also provided with a reciprocating plate 16th: which is reciprocated by an eccentric 168:1 axed to the shaft 88 of head-stock 14a for rotation thereby. The plate 169er also includes a block 178a to which the end 182 of the jig saw blade 184 may be attached for reciprocation by the plate 160a upon rotation of the eccentric 168er.

The probe 121m may als'o be used as a guide fence for jig saw or table saw operation by engaging the tail-stock 16a with a l-ug 120b provided on probe 120a and securing the probe 120a in position across the top of tail-stock 16a by tightening the bolt 220.

Referring to FIGURE 20, the tool 10a may be used as a drill press by sliding the tail-stock 16a to the end 152b of the bed 12a and securely locking it in position by actuating the wheel 46a `after which the tool 10a is brought to a vertical position where it is supported by legs 234 provided on tail-stock 16a. The aperture 50a `provided in tail-stock 16a received the drill bit 134 whi-ch is connected to the shaft 88 in the same manner as that employed in connection with the tool 10. A suitable work piece 136a may then be placed on the wall 16e of tail stock 16a whereupon the head-stock 14a can be lowered toward the Work piece 136a by pushing on the handle 96a which is connected to the head-stock 14a as shown in FIGURE 17. Upon completion of a drilling operation on the work piece 136a, the headstock 14a is readily returned to the end 152a` of the bed 12a with a minimum of effort because of the assistance of the spring 30a which also prevents the head-stock 14a from falling when the tool 10a is in its upright position.
