PROVISIONAL SPECIFICATION.
An Improved Guard for Incandescent Electric Light Globes.
I, WILLIAM HENRY MUNNs, of Victoria Chambers, 55 and 56 Chancery
Lane, in the County of London, Patent Agent, do hereby declare the nature
of this invention (a communication to me from abroad by Joseph Mino, and
W. D. Wastfield, both of Denver, Colorado, U.S.A., Inventors) to be as
follows
-
This invention has reference to an improved guard for preventing the breakage
of incandescent electric light globes. The guard consists of a wire ring, which,
when in position, is located beneath the lamp globe, and is made with interlocking
links, by means of which these two ends can be loosely connected together.
Another ring, also formed in two halves is located about half-way up the lamp
globe, when in position, and is united to the lower ring by means of vertical wires,
which are twisted around it and carried up to the flange of a ring to which they
are secured. This ring is made in two halves, and is hinged together in such
manner that it can be placed and secured around the lamp holder by means of a
set-screw passed through lugs forming a part thereof.
Dated this 21st day of January 1891.

COMPLETE SPECIFICATION. .
An Improved Guard for Incandescent Electric Light Globes.
I, WILLIAM HENRY MUNNS, of 106, 107, and 108 Victoria Chambers,
Chancery Lane, in the County of London, Patent Agent, do hereby declare
the nature of this invention (a communication to me from abroad by Joseph
Mino, and W. D. Wastfield, both of Denver, Colorado, U.S.A., Inventors) and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to guards for protecting the globes of incandescent electric
lights from breakage; and my invention consists in features of novelty hereinafter
fully described, and pointed out in the claims.
In the drawings,
Figure 1 is a side view showing my guard attached to a light-socket.
Fig. 2 is a view of the clamp for securing the guard.
Referring to the drawings, I represents the socket and 2 the globe of an incan-
descent electric light. To the neck of the socket is secured a circular clamp
composed of band-sections 3 and 4, connected at one side by a hinge 5 and provided
at the other side with lugs 6 and 7, connected by a set-screw 8. On the lower
edge of the band-sections 3 and 4 is a flange 9, in which are secured the inner ends
of wires 10, which extend downward and are secured at their lower ends to a wire
ring 11, the ends of which are connected by interlocking-loops 12 and 13, which
allow the inner end of the guard to expand and contract as the clamp 3, 4, is opened
and closed.
14 and 15 are transverse semicircular brace-wires secured near the centre of the
wires 10, disconnected at their adjacent ends, and for the purpose of keeping the
wires in even contour.
The operation of the device is as follows: It will be seen that by unscrewing
the set-screw the clamp can be opened on the hinge 5, which opens the guard at the
inner end so that it can easily be placed over the globe.

page_text: By my invention a very efficient guard is produced and one that can be easily
attached and detached, and when attached is very secure, and one which is of great
value in protecting the globe from being struck and broken, or in cases where the
globe becomes detached for any reason for catching it and preventing breakage
from its falling.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
The guard, substantially as herein shown and described, consisting of the wire
ring 11, having interlocking loops 12 and 13, by which its ends are loosely con-
nected together, the body-wires 10, secured by their outer ends to the wire ring,
the hinged band-sections 34, having lugs 6.7 and flanges 9, and secured to the
inner ends of the body-wires by means of their flanges, and the set-screw 8, working
in the lugs for securing the guard to the socket-neck of an incandescent electric
light..
