Definitions

  • This invention relates to toy cutting apparatus which may be assembled in a variety of forms so as to resemble various woodworking tools; and more particularly to toy cutting apparatus which can be used by children with a high degree of safety.
  • the primary object of the present invention to provide cutting apparatus which differs from conventional powered wood-working tools both in basic design and drive system in such a manner that it would be unsuitable for use as a conventional cutting tool but is specially useful as a toy.
  • One of the fundamental distinctions between apparatus constructed in accordance with the present invention and conventional wood-working machines lies in the type of electric driving motor employed. Machine tools, in' general, utilize electric motors which exhibit characteristics of increasing torque wit-h decreasing speed.
  • the driving motor utilized with the toy cutting apparatus is preferably of the shaded pole type. It has a speed-torque curve in such shape that the driving torque increases with decreased speed only in a narrow speed band around the operating speed.
  • the operating speed of the motor may be 3200 rpm.
  • a toy lathe formed" in accordance with the present invention may be easily stalled by grasping the workpiece without any harm to the hand. Yet, if a tool is applied to the workpiece with a force that does not exceed that which drives the motor into its stalling range, a wide variety of soft woods and plastics may be formed with the lathe.
  • Another safety feature of the present invention resides in the extremely short reciprocating stroke developed by the sabre saw form of the invention. While this limited stroke, which approximates /8, is' sufficient to cut rigid materials such as Woods, plastics, and metals, it will not cut through flesh because flesh is flexible enough to give with this short reciprocating motion so that no cutting action takes place.
  • Another safety factor exhibited by the devices of the present invention is attributable to the form of the machine central unit on which the various woodworking machines, such as a lathe, sabre saw, sanding disc, and
  • This central unit takes the form of an elongated base with vertical members attached to either end.
  • the driving motor is disposed in a horizontal position adjacent to one of the vertical end members and, in one preferred form of construction, may constitute that vertical end member.
  • a pair of horizontally disposed rods are supported between the top sides of the two vertical end members in a horizontal position. These rods are approximately aligned in a horizontal plane which contains the shaft of the driving motor.
  • a dead center is supported on and movable along the rods.
  • Either of the rods is employed as a tool post so that a cutting tool may be rested directly on one of the rods and brought into contact with the work.
  • Use of a full length tie rod as the tool support eliminates the danger of the lathe tool slipping off the tool support and causing an accident.
  • the construction of the central unit centered about an elongated base member, the two vertical end members and the pair of rods disposed at approximately spindle height provides a variety of advantages in addition to the elimination of the need for a tool post and the noted safety factor which accrues thereto.
  • the rods act as structural members, tying the two vertical end members to one another so as to form a rigid, yet light weight, rectangle.
  • force exerted between the live and dead centers are absorbed as tensile forces on the rods. This eliminates the need for a relatively heavy, rigid, dead center mechanism since no twisting moments are exerted on the dead center as they are in a normal lathe construction.
  • a locking post for auxiliary tool members which can convert the devices into a sabre saw or sanding disc or other device is formed on the vertical support member adjacent to the motor and may constitute part of the motor housing.
  • This support cooperates with a tool table which may either be locked into the support post or moveably supported on the two rods in order to form the Various woodworking tools.
  • the design is such that all of the woodworking tools may be assembled and dissembled from the central unit without the use of any hand tools.
  • the primary object of the present invention is to provide toy cutting apparatus which may be assembled in a variety of forms so as to duplicate the operations of various woodworking tools and is simple and lightweight in construction and safe for a child to use.
  • Another object is to provide a toy powered cutting tool which employs a mot-or having an operating characteristic with a relatively narrow band of increasing torque with decreasing speed around the operating speed and a relatively large area wherein the torque decreases with decreasing speed so that the motor may be easily stalled.
  • Another object is to provide a toy cutting tool which may be assembled in a variety of forms, all of which have a central unit for-med of an elongated base with vertical supports at either end of the base, a motor having a horizontal spindle associated with one of the supports, and a pair of horizontal parallel rods disposed in approximately the same plane as the motor spindle connecting the two vertical end members.
  • a further object of the present invention is to provide a toy cutting tool construction built around such central unit wherein a plurality of cutting tools of various configurations may be formed by attaching auxiliary units to the central unit without the use of hand tools.
  • FIGURE 1 is a perspective view of the central unit of an embodiment of the present invention, employed as a lathe;
  • FIGURE 2 is an exploded view of those attachments necessary to convert the central unit into a toy which duplicates the action of a sabre saw;

  • the central unit is constructed about an elongated base 20 formed of a sheet material having its two long edges bent and rebent to form elongated support sections which raise the central section of the base 20 above a supporting structure.
  • a vertical end member 24 is fixed to one short end of the base and extends transversely thereto so as to be in a vertical position when the base is supported on its legs 22.
  • the end member 24 has a V-section 26 removed from the center of its upper end so as to form a pair of diverging legs 28.

  • the frame 32 constitutes a motor housing and is largely contoured with the requirements of the specific motor to which it is applied.
  • the housing has certain properties resulting from the requirements of the present invention.
  • the top of the housing 34 is flat. This flat housing acts in conjunction with other accessories such as a table for feeding work to various implements powered by the motor and certain of the inventive assemblies.
  • the motor is so oriented within the frame 32 that its spindle 38 is disposed in a plane parallel to the base 20.
  • the motor housing 32 also has a tongue 36 extending from the side of the housing which is in opposition to the end member 24. This tongue 36 surrounds the motor shaft 3 8 which extends therethrough and acts as the machine
  • the motor frame itself constitutes the headstock.
  • the tongue 36 has a circular bulge 40" around its center.
  • the tongue 36 and the bulge 40 act as a receptacle for various attachments for the central unit. As will be noted subsequently, these attachments have sections which complement the tongue 36 and which allow the attachments to be fixed to the frame 32.
  • the motor frame 32 also has a pair of ears 42 (only one shown) which are disposed on opposite sides of the frame and receive the ends of a pair of rods 44.
  • rods extend along the length of the unit and are disposed parallel to one another on opposite sides of the spindle 38. They :are parallel to the spindle and a plane passing through the two rods 44 will preferably extend just slightly below the axis of the spindle so that either of the rods may be used as a tool support as is illustrated in FIGURE 1. In any event, this plane should pass within one inch on either side of the spindle.
  • the motor may be supported adjustably on the base 20 so that it may be selectively disposed with its shaft either parallel to or perpendicular to the base 20.
  • the opposite ends of the rods 44 are fixed to the end support 24.
  • the rods act as structural members and tie in the end support 24 with the motor housing to form a closed rectangular structure.
  • the guide member 46 is supported and moveable along the rails 44 and carries a dead center 48 in opposing relationship to the motor spindle 38.
  • the details of the guide 46 are disclosed in FIGURES 6. It constitutes :an elongated bar with a downturned edge 50 on the side facing the motor frame 32.
  • the dead center 48 is fixed in the center of the edge 50 so that it is disposed on an extension of the axis of the motor spindle 38.
  • Each of the ends of the guide 46 is formed with an ear 52 which surrounds one of the rods 44.
  • the ear to the left as viewed in FIGURE 6 is split so as to accommodate a noncircular section 56 allowing the section 56 to be disposed in either the position shown in FIGURE 6 wherein the non-circular section rides freely on the rod 44 or the phantom position 60 shown in FIGURE 6 wherein the large radius section of the member 56 bears against the guide member 46 and thereby is forced against the rod 44 causing the guide to be locked in position along the rods.
  • the guide 46 may be freely moved along the rods 44 by hand, and when the lever 58 is moved into a horizontal position the guide is locked into position on the rods.
  • the guide member 46 also has a central hole 60 formed in its top side for the purposes of receiving certain auxiliary tools as will be noted subsequently.
  • a live center 62 which has three prongs and a central flattened hole adapted to be fitted over the spindle 38 is forced into one end of a cylindrical wooden workpiece 64.
  • the live center 62 has an internal bore which engages a complementary surface on the spindle 38 so as to cause the live center to rotate with the spindle.
  • the guide 46 is then moved against the other end of the workpiece 64 embedding the dead center in the end of the workpiece.
  • the lever 58 is then moved into a locked position and the unit is ready for use.
  • An electrical switch 66 associated with the motor and connecting the motor with a power line (not shown) energizes the motor.
  • the device is then used like a normal wood lathe and a lathe tool 68 is supported on one of the rods 44 and applied to the rotating workpiece 64.
  • the motor employed in the preferred embodiment is of the shaded pole variety. An approximate speed-torque curve of such a motor is shown in FIGURE 10. The motor reaches maximum torque at a speed slightly below its normal operating speed. After that point is reached, the torque of the motor decreases as its speed is decreased. Therefore, if the motor encounters an obstruction which causes its speed to drop below the point at which torque increases, the motor will then stall. As has been noted,
  • the parts shown in FIGURE 2 are attached to the central unit. They comprise the saw support 70, a cam driving unit 72, and a saw table generally indicated at 74.
  • the saw table is preferably a casting having a flat table surface 76 with downturned edges 78 on opposite sides.

  • the cam drive member 72' is simply a cylindrical member having off-center bore 104 which is shaped to receive the driving spindle 38.
  • the saw support has a fine tooth saw member 106 projecting from one end and has an internal cavity formed in a member 108 which is adapted to receive the driving cam 72.
  • the table 76 forms an extension of the flat top 34 of the motor housing 32 so that work may be supported on the combined table and brought into the contact with the saw 106.
