DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to the drawings, and more particularly to FIG. 1
thereof, numeral 1 has been applied to indicate the housing of a
flashlight. Housing 1 is substantially in the shape of an elongated
tubing and preferably made of a synthetic resin or a plastic
material. The front end of the housing 1 of the flashlight has a
portion 1" which is in the shape of a frustum of a cone, and has
cylindrical externally screw-threaded extension 1"' on which an
internally screw-threaded clamping ring 2 is mounted. Clamping ring
2 is intended to secure to flashlight housing 1 an integral unit
including a light-transmittant lens 3, a chuck 4 for
interchangeably, or selectively, supporting tools 5 such as, for
instance, a screwdriver, and a concave reflector 11. The latter has
not been shown in FIG. 1, but has been clearly illustrated in FIG.
4. Housing 1 defines a substantially cylindrical chamber 1a for
receiving a dry cell 6 intended to energize an incandescent lamp 7
arranged in the center of reflector 11 and supported by the latter,
as will be set forth below more in detail in connection with FIGS.
4 and 7. The bottom of dry cell 6 rests upon a resilient angularly
bent end portion 8a of a contact strip 8 establishing a current
path including incandescent lamp 7. This current path is controlled
by a switch of which but its operating member 9 has been shown in
FIG. 1. Housing 1 is subdivided by a transverse partition 1' into
the aforementioned chamber 1a for receiving dry cell 6, and a lower
chamber 1b intended to receive a variety of tools to which
reference character 5 has been applied. Tool chamber 1b is closed
by a cap 10 which may readily be removed from housing 1, thus
giving access to various tools inside of chamber 1b of which each
may readily be interchanged with the screwdriver 5 shown to be
inserted into chuck 4. The increase in length of housing 1
resulting from the provision of tool-storing chamber 1b makes it
possible for housing 1 to be handled more readily, and to be
inserted deep into relatively dark spaces wherein some work is
intended to be performed calling for the use of one of the tools
inserted into chuck 4. The outside of housing 1 is preferably
slightly outwardly flaring from the bottom end thereof to the tool
end or lens end thereof. The cross section of the outer surface of
housing 1 is preferably in the shape of a multisided polygon to
facilitate the handling thereof.
The same reference characters as in FIG. 1 have been applied in the
other figures to indicate like parts. Therefore FIGS. 2 to 9
require a detailed description only to the extent that the
structures shown therein differ significantly from the structure
shown in FIG. 1, and described in connection with this figure.
The structure shown in FIG. 2 differs from that shown in FIG. 1 on
account of the fact that it is adapted to house two superimposed
serially connected dry cells 6 for energizing incandescent lamp 7
rather than but one single such cell. These dry cells 6 are
arranged in a cell chamber 1a which occupies substantially the
entire length of housing 1. Cells 2 have a relatively small
diameter, and cell chamber 1a is laterally bounded by cylindrical
partition 1c arranged in coaxial relation to the outer wall 1d of
housing 1. Radial webs 1e extend between the outer wall 1d of
housing 1 and cylindrical partition 1c, thus forming a plurality of
segregated tool-receiving chambers 1b. A pair of the aforementioned
radial webs 1e defines a groovelike recess 1f receiving
current-carrying strip 8 whose angularly bent contact end 8a forms
a support for the two dry cells 6. Recess 1f is open toward
cell-receiving chamber 1a so that the resilient angularly bent
lower end 8a of current-carrying strip 8 may project from recess 1f
into the chamber 1a.
It will be apparent from FIG. 2 that the compartments into which
tool-receiving chamber 1b is subdivided by radial webs 1e have open
ends at the side of the housing 1 remote from incandescent lamp 7,
these open ends being situated within housing 1. The end of housing
1 remote from incandescent lamp 7 is provided with a cap or cover
means 10 for restraining any of the tools which may be placed into
the aforementioned compartments. The dry-cell-receiving chamber 1a
formed by cylindrical partition 1c is closed by bottom portion 1'
at the end remote from incandescent lamp 7 and open at the end
thereof adjacent incandescent lamp 7, as shown more in detail in
the figures which are described below.
It will be apparent from a comparison of FIGS. 1 and 2 that the
structure of FIG. 2 is shorter than that of FIG. 1 because the
superimposed and serially connected dry cells 6 involve a smaller
aggregate length than that of the single dry cell of FIG. 1 plus
that of tool chamber 1b of FIG. 1.
Referring now to FIGS. 4 to 9, inclusive, the principal difference
between the structure shown in FIGS. 1-3 and that shown in the
other figures resides in the fact that the dry cell chamber 1a of
the flashlight shown in FIGS. 4 and 5 is arranged in noncoaxial
relation with its housing 1 or, in other words, the dry cell
chamber 1a is situated off center. Thus the outer wall of housing 1
and the internal cylindrical partition 1c thereof define jointly a
tool-receiving chamber 1b which is substantially sickle-shaped in
transverse cross section as can best be seen in FIG. 5. The width
of tool-receiving chamber 1b at the end thereof remote from its
pointed end is relatively large, and therefore lends itself to
receiving relatively bulky tools 5, or tools having a shank of
relatively large diameter. The axis of tools 5 in chuck 4 and the
axis of the incandescent lamp 7 are parallel to, but spaced from,
the axis of dry cell 6. Parts 3, 4 and 5 are arranged in coaxial
relation to casing 1. While the structures of FIGS. 1 and 2 allow
the provision of conventional contact means between the upper
center contact, or contacts of dry cells 6 and the sockets (not
shown in FIGS. 1 and 2), of incandescent lamps 7, the structure of
FIGS. 4 to 6 calls for an unconventional socket for incandescent
lamp 7 on account of the eccentric arrangement of dry cell 6 and
incandescent lamp 7.
As shown in FIGS. 4 to 9 the concave reflector 11 is provided at is
apex portion with a tubular coaxial extension 11a forming an
integral part of reflector 11. Mounted on extension 11a is a metal
sleeve 12 provided with an internal screw shell or screw socket 12a
for incandescent lamp 7. Screw shell, or screw socket 12a is
surrounded by a sleeve 13 of insulating material. The upper edge of
insulating sleeve 13 abuts against a shoulder formed by metal
sleeve 12, and insulating sleeve 13 engages frictionally the outer
surface of screw shell, or screw socket 12a. The lower end of
insulating sleeve 13 is provided with a flange 13a extending
radially outwardly from the sleeve proper. A circular metal cap 14
is crimped at 14a around flange 13a of sleeve 13. The bottom of cap
14 is provided with a substantially U-shaped slit 14c, thus
defining a resilient metal tab 14b. Metal tab 14b projects
sufficiently far radially outwardly to engage the upper center
terminal of dry cell 6, thus making it possible to establish a
current path through incandescent lamp 7.
Dry cell 6 is biased upwardly by spirally wound spring 8a resting
upon an angularly bent portion of current conductor 8 leading up to
a switch of which but slide handle 9 has been shown in FIG. 4.
Slide handle 9 has a cam (not shown) engaging current conductor 8.
In the lower limit position of slide handle 9 current conductor 8
is allowed to flex radially outwardly out of engagement with the
lateral wall of the shoulder portion of metal sleeve 12. In that
position of slide handle 9 the current path through incandescent
lamp 7 is interrupted. Raising of slide handle 9 to its upper limit
position causes engagement between the upper end of resilient
current conductor 8 and the shoulder portion of sleeve 12, as
clearly shown in FIG. 4. This establishes a current path energizing
incandescent lamp 7. This current path is as follows: Lower
terminal of dry cell 6, spring 8a, current conductor 8, sleeve 12,
screw shell or screw socket 12a integral with sleeve 12, filament
of incandescent lamp 7, center contact of incandescent lamp 7, tab
14b, upper terminal of dry cell 6.
Reflector 11 and parts 12, 12a, 13 and 14 form a subassembly. This
subassembly is established by mounting sleeve 12 on tubular
extension 11a of reflector 11 which forms an integral part of the
former. Lens 3 is preferably made of a colorless transparent
plastic. Lens 3 defines on its inside a coaxial cylindrical cavity
3' having substantially the same inner diameter as the outer
diameter of an upstanding cylindrical portion 11' of reflector 11.
When the subassembly 11, 12, 12a, 13 and 14 engages with the
aforementioned cylindrical projection 11' the cavity 3' of lens 3,
the subassembly 11, 12, 12a, 13 and 14 is frictionally supported by
lens 3.
It will be apparent from the above that the three embodiments of
the invention illustrated and described are intended to be
illustrative rather than to limit the invention.
