Abstract
ABSTRACT OF THE DISCLOSURE
In one embodiment, a battery case and lamp as-sembly detachably engage with a pair of clips secured to the front of the helmet. In the preferred embodiment a lower horizontal rod attached to the back of the battery case clips into a pair of clips secured to the front of the helmet and a pair of resilient claws at the top of the battery casing, detachably engage any one of a plu-rality of projecting teeth, also secured to the front of the helmet. The case and lamp assembly pivot around the horizontal rod so that the angle of the lamp assem-bly can be adjusted to suit the user. Switch means are provided for the lamp assembly to connect and disconnect same from the batteries within the battery case.

Description
- - - - -:7 - -15 l BACKGROUND OF THE~ INVENTION
.
This invention relates to new and useful improve-ments in lamp assemblies particularly adapted for use with protective hats such as helmets, hard hats and the like.
. .
Users of protective hats such as f.iremen, rescue workers and the like, often require illumination without interfering with the use of both hands and many attempts have been made to provide head held lamp assemblies for this purpose.
Examples known to the applicant include u.s.

SUMMARY OF THE INVENTION
The present invention is believed to overcome the :
disadvantages and in accordance with the inventionJ there is provided a lamp assembly for the front of a protective hat such as a helmet hard-hat and the like, comprising in combination a battery case for detachably receiving dry batteries and a ~:
lens assembly secured to said battery case and being operative-ly connected to the batteries within the battery case, and means to detachably secure said assembly to the front of the associated protective hat, said means to detachably secure said assembly to the front of the associated protective hat includ-ing means to adjust, within limits, the angle of the lamp as-sembly in a fore and aft position relative to said protective 25 hat, said means to adjust the angle of the lamp assembly includ- :
ing a longitudinal pivot attachment of the lower side of said battery case to sa.id protective hat, at least one resilient ~s -2-c~' leg extending rearwardly of said battery case adjacent the upper side thereof and means on said front of said protective hat selectively engageable by the distal end of said leg to de-tachably hold said lamp assembly in the desired angle relative to said protective hat.
Another advantage of the present device is that it is simple in construction, economical in manufacture and other-wise well suited to the purpose for which it is designed.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

S2~
A lens assembly 15 is secured to the front panel 16 of the battery case and preferably is partially rotatable to act as a switch 17 (see Figure 4) to open and close the circuit between the lamp 18 and the battery 14.
Means are provided to detachably secure the ' assembly to the front of the helmet 10 and take the form of a pair of plates 19 secured by means of screws or ri~
vets 20 to the front of the helmet in spaced apart rela-tionship. Open sided vertically situated jaws 21 are formed on the inner sides of the plates 19 and substan-tially cylindrical rod portions 22 are formed on each side of the battery case 12 adjacent the rear side thereof.
These rods are adapted to slide vertically within the jaws 21 so that the assembly may be engaged and disengaged from the helmet readily and easily as clearly shown.
~.~
Preferred embodiment is shown in Figures 2 and
3 and once again is secured to the front portion 23 of the helmet just above the front peak portion 24.
It also includes the battery case 12 with the hinged lid 13 so that access may be obtained to the battery cells 14 within. A lens and lamp assembly lS is secured ~;
to the front panel 16 in a manner similar to that herein- ;
-- 5 ~
5;~3 before described and switch 17 may also be incorporated to operatively connect and disconnect the lamp 1~ from the battery cells 14 In this embodiment, a pair of members 25 are secured to the front 23 of the helmet in spaced apart relationship by means oE rivets 26 or any other suitable means. A horizontal rod 27 is provided spanning the rear lower side of the battery case and this rod snap engages within jaws 28 formed on the lower ends of each of the members 25 thus mounting the lamp assembly 11 to the hel-met for fore and aft pivotal movement around the axis of the horizontal rod 27.
Means are provided at the upper end of members 25 to detachably hold the lamp assembly in the desired position relative to the front of the helmet and in this embodiment, a pair of resilient legs 29 extend rearwardly from the battery case adjacent the upper rear side there-of, each leg having a down-turned clip portion 30 formed thereon. These portions are preferably made from synthe-tic plastic, but of course metal clips can be used if de-sired.
Tooth members or portions 31 extend forwardly from the upper end of each of the members 25 wit~ the in~
dividual teeth 32 extendin~ ~pwardly therefrom and the ~35~"3 claw or clip 30 of the legs snap engages between these teeth as the lamp assembly is moved forwardly or rear-wardly, pivoting around the axis of the transverse rod s 27 thus making an easlly adjusted and easily detached assembly for a safety hat or the like.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from .
such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
It also includes the battery case 12 with the hinged lid 13 so that access may be obtained to the battery cells 14 within. A lens and lamp assembly lS is secured ~;
to the front panel 16 in a manner similar to that herein- ;

A horizontal rod 27 is provided spanning the rear lower side of the battery case and this rod snap engages within jaws 28 formed on the lower ends of each of the members 25 thus mounting the lamp assembly 11 to the hel-met for fore and aft pivotal movement around the axis of the horizontal rod 27.
Means are provided at the upper end of members 25 to detachably hold the lamp assembly in the desired position relative to the front of the helmet and in this embodiment, a pair of resilient legs 29 extend rearwardly from the battery case adjacent the upper rear side there-of, each leg having a down-turned clip portion 30 formed thereon. These portions are preferably made from synthe-tic plastic, but of course metal clips can be used if de-sired.
Tooth members or portions 31 extend forwardly from the upper end of each of the members 25 wit~ the in~
dividual teeth 32 extendin~ ~pwardly therefrom and the ~35~"3 claw or clip 30 of the legs snap engages between these teeth as the lamp assembly is moved forwardly or rear-wardly, pivoting around the axis of the transverse rod s 27 thus making an easlly adjusted and easily detached assembly for a safety hat or the like.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from .
