Improvements in Protectors and Holders for Electric Incandescent
Lamps, Thermometers, and other Articles.
I, FREDERIC HUGHES, of No 20, Paget Road, West Dulwich, Engineer, do
hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
The
My invention relates to improvements in connection with holders for in-
candescent lamps and other articles and although more especially intended for
use with incandescent lamps protected by a cage or perforated cylinder can never-
theless be wholly or in pait adapted for use with other articles such as thermometers
and other apparatus The objects are to reduce the liability of the lamp or other
article to breakage and to facilitate the removal and replacement of the said lamp
or article. In order to more clearly indicate the nature of my invention I make
reference to the accompanying drawings of which Fig 1 is a part sectional side
view of the complete arrangement as applied to un incandescent lamp and Fig 2
a side view of a portion of such arrangement a is the lamp, one end of which 18
placed in a split socket b consisting essentially of a band having in it slits e
socket is supported by the base d round which is screwed the ring e carrying the
lower ends of the bara f forming the cage which protects a The upper ends of f
are attached to an internally screw threaded crown piece into which 18 screwed
the rubber tipped terminal h Into g sciews the thimble having a notch at its
blind end for the reception of the point of a screw driver by which can be
screwed up and down within g Within the somewhat overlipped open end of 2
is a moveable disck between which and the end, is a spiral spring or equivalent 7.
In the centre of k is a hole to freely admit the sealing point of the lamp a Pro-
jeoting through d are the central contact pieces m connected with some source of
electricity and conveying the current to the lamp a. d is screwed or otherwise
attached to the enlarged end n of the rod o through which pass the wires to m
To remove a, h is taken out and raised by operating a screw driver in the
notch at 7
The ring e is then taken off and with it of course the cage
then be removed from the socket b The rubber tip of h 18 to prevent concussion
when the apparatus 18 put point downwards as when employed as a search light for
exploring the interior of casks and other receptacles
a can
The invention is also applicable to cases where the cage is replaced by a
cylinder or tube having in it openings for the inspection of the lamp or other
article within
Although I have assumed in the above description that the invention is applied
to an incandescent lamp, nevertheless as already mentioned, it may be employed
wholly or in part for any other purpose to which it may be found applicable For
this reason I do not confine myself to the precise shapes, relative proportions or
dispositions of parts described in the above specification or exemplified in the
accompanying drawings as considerable variation is possible without departure
from the essential features of the invention

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim 18:
-
1 In holders for incandescent lamps or for other articles which can be similarly
held, a split socket for receiving the lower end of the lamp or other article, the
said socket when employed with incandescent lamps being screwed or otherwise
attached to a suitable base having central contact pieces for conveying the electric
current into the lamp, the whole substantially as described in the above specifica-
tion and exemplified in the accompanying drawings
2. In combination or not with a socket such as is mentioned in the preceding
claim a resilient holder for receiving the sealing point of the lamp or the equivalent
part of any other articles which can be similarly held, the said resilient holder
consisting essentially of a disc movable within an outwardly screw threaded thimble
having a closed end, between which and the disc is a spiral spring or equivalent,
the said thimble screwing into a crown piece which is connected with a ring
surrounding a base carrying the socket (when used) by bars forming a cage or by
a cylinder or other means, the whole substantially as described in the above
specification and exemplified in the accompanying drawings
3 In holders for incandescent lamps or for other articles which can be similarly
held the combination of parts consisting essentially of a split socket to receive one
end of the lamp or other ai ticle above which socket is supported by a cage or equiva-
lent a resilient holder for the other end of the lamp or other article, the whole
substantially as described in the above specification and exemplified in the
accompanying drawings
