COMPLETE SPECIFICATION.
Improvements in and relating to Lamp Shades.
We, WALLACE BIERCE CURTIS and CHARLES HIMROD, citizens of the United
States of America, residing respectively at Pomeroy, in the County of Meigs and
State of Ohio, and at Jackson, in the County of Jackson and State of Ohio, one of
the United States of America, Gentlemen, 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:-
This invention relates to certain new and useful improvements in lamp shades,
designed more particularly for incandescent lights, and it has for its object, among
others, to provide an improved shade which may be used for a reflector or for a
protector from flies and other insects, or against damage to the lamp.
We so construct and arrange the parts that one section or both may be opened,
the two sections being hinged together, each being provided with separate and
independent means for holding it in its adjusted position. We provide novel
hinges by which glass sections may be connected.
Other objects and advantages of the invention will hereinafter appear, and the
novel features thereof will be specifically defined by the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with
the letters of reference marked thereon, form a part of this Specification; and
in which-
Figure is a side view with the two sections open and shown in longitudinal
section.
Figure 2 is a side elevation with both sections opened, looking at right angles to
the hinge.
Figure 3 is a view looking at right angles to Figure 2 with one section of the
shade closed and the other open.
Figure 4 is a perspective view of a collar designed to be placed between the
hinges and to which the hinge wires or rods are connected.
Figure 5 is a sectional detail showing a hinge for holding up one half of a glass
shade.
Figure 6 is a perspective view of the other portion of the hinge.
Figure 7 is a detail in top plan showing the spring attached to the shade.
Like letters of reference indicate like parts throughout the several views.
Referring now to the details of the drawings, by letter, A, designates an
incandescent lamp bulb of known construction.
B, is a split collar provided with cars, , through which a set screw or other
analogous means, is designed to pass to clamp and hold the ends together and the
collar around the metallic stem of the lamp. From diametrically opposite sides of
this collar extend the wires or rods, D, which serve as the pintle on which the
shade-sectious turn, as will hereinafter appear.
E, are the shade sections which may be formed of any suitable material according
to the use to which they are to be put. In some cases we form them of glass or
opal; in others with a light wire frame covered with paper or other desired
material. At other times we may form them of sheet metal, or a light frame
covered with tin foil or the like; they may be as fanciful as desired.
In Figure 5 we have shown a section of one hinge adapted to receive a flange or
rim on the shade section. In this view, E, is the shade section formed with the
Hange or rim, b, adapted to be slipped into the correspondingly-shaped socket, c, of
the hinge portion, F, said hinge portion having a bored portion, d, to receive the
wire, D. The hinge portion has also inwardly-extending lips, e, at the opening into

page_text: the socket, as seen in Figure 6, to hold the flange or rin on the shade, as seen in
Figure 5.
The hinges may be varied in form to suit the different varieties of shades
employed. When we employ shade sections of cloth or the like, the hinges may be
formed by uniting the adjacent edges of the shade sections and applying a strip over
the wires or rods, D, and securing the same at its edges to the upper faces of the
adjacent edges of the shade sections, as will be understood from Figure 3.
The shade sections should be each formed with a depression, of a shape corre-
sponding to the shape of the bulb, as seen in Figures I and.3, so that when the two
sections are closed, as shown by dotted lines in Figure 1, they will embrace the
bulb and yet allow the shade sections to come close together, as indicated by said
dotted lines.
In order to hold the shade sections in their open position each independent of the
other, I provide each with a wire spring, G, attached at one end to the shade
section and the other end free, and near the free end curved, as shown best in
Figure 5.
These spring arms are designed to automatically engage a pin or projection, g, on
the collar, B, as seen in Figure 3, the said spring arms being arranged out of plane
with each other so as to allow them to pass one another. As the shade section is
thrown up the spring arm thereon will ride over the pin, and as it passes the curve
it will hold the section from falling down, as seen in Figures 3 and 5.
When the shade is to be used in a sick room they may be made of coloured glass
and used with either one closed and the other open or both closed as preferred.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The combination with the collar and its rods, of the shade sections hinged
upon the said rods and adapted to be moved independently of each other and cach
formed with a depression to receive one half of the bulb cut away at the upper end
and their lower ends extended beyond the bulb, substantially as specified.
2. The combination with the collar and its rods, of the shade sections indepen-
dently movable upon the rods, the spring arms on the shade sections, and the pin on
the collar, substantially as specified.
3. A hinge portion for the purpose specified, formed with a socket to receive a
rim on a shade section, and inwardly extending lips and a bored portion to receive
its pintle, as set forth.
4. The combination with a shade section formed with a rim, of a hinge portion
having a socket of a shape corresponding with that of the rim, lips at the entrance
to the socket, and a longitudinal bore, as and for the purpose specified.
Dated this 27th day of January 1891.
