Improvements in Lamps Requiring Shade Rings.
JAMES LIND and JOHN LIND, (trading as James Lind & Son, and also as
The Liverpool Lamp Company) of 61 Great George Street Liverpool in the
County of Lancaster, Lamp Manufacturers do hereby declare the nature of this
invention to be as follows
Our invention consists of certain improvements in the manner of attaching the
ring for supporting the usual reflecting shades, to suspension and other lamps.
This is at present generally effected by means of two or more small screws, and is
found to be inconvenient and troublesonie, involving often much loss of time.
Our improvements consist of hingeing in a suitable manner the shade ring to the
lamp frame so that the said ring is collapsible for safety and economy in packing
and yet readily and accurately set into position, and retained so by means of a
spring or its equivalent.
The hinge may be made detachable or as a fixture to the lamp frame.

COMPLETE SPECIFICATION.
Improvements in Lamps Requiring Shade Rings.
We JAMES LIND and JOHN LIND (trading as James Lind and Son and also as
The Liverpool Lamp. Company) of 61 Great George Street Liverpool, in the
County of Lancashire, Lamp Manufacturers do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
dèscribed and ascertained in and by the following statement :-
This invention relates to certain improvements in the manner of attaching the
ring for supporting the usual reflecting shades to suspension and other lamps.
This is at present generally effected by means of two or more small screws, and is
found to be inconvenient and troublesome, involving much loss of time.
Our improvements consist of hinging in a suitable manner, the shade ring to. the
lamp frame, so that the said ring is collapsable or detachable for safety and economy
in packing and yet readily and accurately set into position and retained so by
means of a spring or its equivalent.
By referring to the accompanying drawings
Figs. 1 and 4, exhibit two. methods of accomplishing the object to be attained,
Fig. 1 of which the details are drawn enlarged at Figs. 2 and 3, illustrating a
detachable hinge; and Fig. 4 with details shown at Figs. 5 and 6, a hinge fixed or
integral to the lamp frame.
In Fig. 1 the shade ring A, is set in position on the lamp frame Y, and supporting
the usual reflecting shade X, while Fig. 4, illustrates the shade ring A, hinged
back parallel to the lamp frame Y, for convenience of packing; the operation
being readily performed by our improvements in a few seconds, which under the
old system would probably require much time and patience, according as the
drilling & screwing and fitting of the shade ring to the lamp frame had been
originally well or ill performed.
The manner of construction of hinge or its equivalent is immaterial to the object
to be attained, although two suitable forms of same are now described, and shown
in detail on the accompanying drawings, it is evident that equivalent adaptations or

page_text: modifications would fairly fall within the scope of the present invention; while the
same reservation is also made in respect of the snap spring or swivel catch fastening,
hereinafter described; as a means of holding the said hingeds hade ring in position
on the lamp frame.
Figs. 1, 2 and 3 exhibit an arrangement by which the shade ring A, is detachable
from the lamp frame Y. In this form of hinge (see Figs. 2 and 3) the lower half
of detachable hinge is formed upon a supporting scroll or ornament B, having a
slot C, in the raised end D. The other part of hinge is attached to the shade
ring A, and is provided with a tail piece F, which engages and acts in the slot C.
The top half of hinge E, may be of malleable metal, and provided on its upper
surface with a small round or square rivet piece J (Fig. 3), forming a rivet with
which to attach to the shade ring A. The snap spring H, is so shaped as to lie
between E and A, so that the same rivetting operation may secure all these parts
together. When the shade ring A, is in position as at Fig. 2, the snap spring H,
engages under the end I of the supporting scroll B. In this arrangement it is
evident that a suitable swivel catch may be employed in lieu of the snap spring H.
We now proceed to describe a form of hinge by which the shade ring is not
detachable from the lamp frame (see Figs. 4, 5 and 6). Thus Fig. 4, shows the
shade ring A, hinged back for packing etc., with swivel catch O, moved aside
Fig. 5, is an enlarged view with portion of the shade ring shown in position, and
Fig. 6, also an enlarged view, showing the separate parts forming the hinge and
swivel catch.
In this arrangement (see Figs. 5 and 6) the supporting piece B, is slotted and
drilled as at K, so that the small metal piece L, which is provided with a rivet
shank M, may freely act on a pin N, which passes through the holes S. The
swivel catch O, is rivetted to the shade ring A, as at P, so that it may open or
swing aside as shown at Fig. 4, and also engage in position as at Fig. 5; and much
additional power is gained by prolonging the end of the catch O, as at V,
what beyond the rivet P. A suitable snap spring may also be employed in lieu of
the swivel catch O, and a piece of metal, doubled as at Q (see Fig. 6) may be used
instead of the metal piece L, the ends being passed through a slot in the shade
ring A, and opened out as at R, R, to attach the same securely together.
some-
Any desired number of suitable hinges, or of snap springs or swivel catches may
be employed in any lamp.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we now declare that what we
claim is:
1. In hanging lamps such as described, the shade ring collapsable or detachable,
by means of a hinge or hinges, or their equivalent.
2. In hanging lamps such as described, one or more snap springs, or swivel
catches, or combination of same, in order to retain the shade ring in position.
3. The general arrangement and construction of the parts comprising the hinge
with shade ring detachable and of the suap spring, or alternative swivel catch, as
described and shown at Figs. 1, 2 and 3, substantially as and for the purpose
specified.
4. The general arrangement and construction of the parts comprising the hinge,
with attached shade ring, and of swivel catch, or alternative snap spring, as
described and shown at Figs. 4, 5 and 6, substantially as and for the purpose
specified.
