Toy DRILL Filed sept. 15, 195o a INVENToR.

DAN/E L WE EDEN WOOD A TTORNE Y Patented Feb. 10, 1953 UNITED STATES PATENT OFFICE TOY DRILL Daniel Weeden Wood, Akron, Ohio Application September 15, 1950, Serial No. 185,019 4 anims. (c1. 465-39) This invention relates to toys and in particular relates to a toy rotary tool.

One object of this invention is to provide a toy rotary tool simulating in appearance an electric drill, but which will not, however, be injurious to surfaces on which the same is applied by a child.

Other objects of the invention will be selfevident from the following brief description and the accompanying drawing.

Of the drawing:

Figure l is a side elevation of one embodiment of the invention.

Figure 2 is a similar view partly broken away and in section showing the driving means in detail.

Referring to the drawing, there is shown a toy rotary drill I0, including housing members II"and I2, complementally assembled to form a drill housing I3 having a handle i3d and enclosing driving means I4 for rotating an axially shiftable simulated drill I5, the same normally having one free end I5@J thereof extending outwardly through an opening I5 in the housing member I2, while the drill I5 is retained in yieldingly, axially shiftable relationship to said housing by spring means to be described later.

Referring now to Figure 2 for a particular consideration of the driving means lf3, the drill I5 is shown positioned between axially aligned, out-turned flanges 2| and 2li, in housing I2 and a spring housing 25, respectively, the spring housing being amxed to the housing I2 in known manner. A bevelled friction wheel 25, affixed to the opposite end |51) of the drill I5, is maintained in axially disengageable driving engagement with a complementally bevelled friction wheel 21, mounted on one end 35a of a shaft 33, the same being journalled on spaced bearings 3| and 32 attached to housing member II. For allowing said axial disengagement a compression spring 28 is positioned around the drill I5 and is operable between the inner face of the top portion of said housing 25, and a collar 29 fixed on the central portion of the drill to urge the friction wheels 2B and 21 out of driving engagement in a manner to be described. On the opposite end of shaft 30 may be provided a suitable bevel gear 34 in meshing engagement with a similar bevel gear 35, mounted on an outwardly extending shaft 36 of a motor 3l which is affixed to the housing member I I, as shown. The motor is provided with dry-cell battery energizing means 40, controlled in known manner by an on-off switch 4I provided on the exterior of the housing II.

' rotate the drill shaft.

' In simulation of an electric cord forv attachment to a wall outlet, a length of string attached to the housing member II, may have a two pronged plug 48 on the free end thereof.

For preventing the ange 2| from scratching or marring table or other surfaces, when the toy is used in a manner to be described, a cupshaped cap 49 of rubber or similar resilient material is tightly tted over the same, the cap having a central aperture 50 therein for reception of the drill I5 therethrough.

In use or operation of the improved device, as for example by a small child in play, the child grips the handle I3a of the drill and operates the switch 4I to the on position as shown in Figure 2, whereupon motor 3'I will be energized to rotate the motor shaft 35 and thereby through

gears

34 and 35 rotate shaft 30. Rotation of shaft 30 through frictional engagement of the

friction wheels

21 and 26 on the shaft 35 and on drill shaft' I5, respectively, is effective to The child, by applying downward pressure on handle I3a, while the rounded outer end of rotating drill shaft I5 -is held against a surface, will cause the drill shaft to be moved inwardly of the housing, against the action of spring 28, until the rubber cap 50 engages said surface. This inward movement of the drill shaft moves friction wheel 26 out of driving engagement with the friction wheel 21 as shown in chain-dotted lines in Figure 2, and hence rotation of the drill shaft is also stopped. This action provides an illusion that the drill shaft has bored a hole into the surface, but in reality no damage is done thereto. Upon lifting the rotary drill I0 from said surface the spring 28 is effective to move drill shaft I5 outwardly toward reengagement of wheel 26 with wheel 21, to start rotation of the drill shaft once more.

While the invention has been described as employing a battery-operated motor or driving means, it is clear that a spring-wound mechanism may be substituted without material changes in the inventive concept.

Other modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.

What is claimed is:

l. A toy simulated portable power tool, comprising a housing having an apertured portion, bearing means in said housing, a stem journalled in said bearing means and being axially shiftable with respect thereto, said stem having an extension simulating a rotary implement, spring means normally urging said stem to protruding position through said apertured portion, said ex- 3 t tension having a smoothly rounded non-cutting outer end, a driven member fixed on said stem within said housing, a driving member in said housing normally held in driving engagement with said driven member by action of said spring means, power means for driving said driving member to drive said driven member and thereby rotate said stem and extension, said driving and driven members being disengageable by pressing said stem extension against a surface yieldingly to shift the stem axially inwardly.

2. A toy simulated portable power tool, comprising a housing having an apertured neck portion, a cap of resilient material secured to said neck portion to protrude freely outwardly of the casing, bearing means in said housing, a stem journalled in said bearing means and being axial 1y shiftable with respect thereto, said stem having an extension simulating a rotary implement received through said apertured neck portion,

spring means normally urging said stem to protrude outwardly of said cap'from an inward nonprotruding position of the extension, said extension having a smoothly rounded non-cutting 4outer end, va driven member fixed on said stern within said housing, a driving member in said housing normally held in driving engagement Ywith said driven member by action of said spring means, power means for driving said driving member to drive said driven member and thereby rotate said stem and extension, said driving and driven members being disengageable by pressing said stem extension against a surface yieldingly to shift the stem axially inwardly to said non-protruding position of the extension.
