"IMPROVEMENTS IN THE GLASS HOLDERS OF GASELIERS AND LAMPS."
This Invention consists in attaching to the arms or brackets carrying the globe
or glass of a lamp or gas burner loose clips pinned to the arms. These clips are
formed at one end into a hook, and at the other end into a balance weight, so that
the globe being placed in tho hooks the clip is by the weight of the globe tilted
until the balance weight end of the clip touches the outside of the globe, and thus
holds it between the book inside and the balance weight outside.

IMPROVEMENTS IN THE GLASS HOLDENS OF GASELIERS AND LAMPS."
Hitherto gas and other shades have been secured by means of one, two, or more
screws, which if not carefully adjusted frequently fractured the shade when made
of glass, and were very liable to be lost.
The object of my Invention is to provide a simple, easy, and effective moans for
fixing or removing a gas or lamp shade or globe with perfect safety.
I will now with the aid of the accompanying Drawings, whereon similar numbers
indicate corresponding parts, proceed to particularly describe the same.
Instead of the ordinary triangle and screws I employ a triangle or its equivalent,
one or more of the arms of which terminate at their outer extremities in two
dwarf arms (1, 1,) between which is a small recess (2), wherein a clip arm (3) is
placed and secured by a pin or rivet (4) in such a manner that it oscillates freely to
and fro.
- One end of such clip arm (3) is formed into a hook (5), which forms the clip (6),
and affords a safe lodgment for the rim of the shade, while the other end is formed
into a balance weight. On the back of such clip arm is a shouldér (7), through
which the rivet passes which secures it in position.
The operation of my improved clip holder is as follows:-The triangle or its
equivalent fitted with my improved clip holder having been fastened to the arm
of a gaselier or bracket, or to a lamp, the shade or globe is dropped into the clip or
clips, which latter owing to the weight of the shade or globe become tilted until
the balance weight end or ends touch the outside of the globe or other shade, thus
holding it securely in position between the clip hook formed on the inside and the
balance. weight outside. To remove the shade it is only necessary to slightly raise
the outer extremity of one of the clip arms, when the rim of the shade becomes
dislodged from the clip hook, and it can at once be lifted out.
In casting the clip arm the recess formed by the. clip hook is made sufficiently
large to allow of the expansion and contraction of the shade or globe without
fracturing the same.
Such improved clip holder may be made of any convenient dimensions and
pattern, and is equally adapted for use for gas and other lamps.
Figure 1 of the Drawings shows the clip arm rivetted to one of the arms of a
triangle.
Figure 2 shews a separate view of such clip arm, and Figure 3 shews the two
dwarf arms formed at the outer extremity of each of the arms of the triangle
or its equivalent, while Figure 4 shows the globe or shade in position in the clip
arms.
I claim as novel and as my Invention, the principle of fitting one or more of the
arms of a triangle or its equivalent with a clip arrangement, substantially in the
mauner and for the purposes bereinbefore described and illustrated.
In witness whereof, I, the said James Gordon, have hereunto set my hand
and seal, this Twelfth day of December, in the year of our Lord One
thousand eight hundred and eighty ono.
