PROVISIONAL SPECIFICATION.
An Improved Method of and Means for Holding the Bases of Electrical "
Fittings within Boxes or upon other Surfaces.
I, FREDERICK BATHURST, of No. 4, Limes Villas, West Hill Road, in the
County of London, S.W., Electrical Engineer, do hereby declare the nature of
this invention to be as follows:-
My invention relates to an improved method of, and means for holding the
bases of electrical fittings within boxes or upon other surfaces, and is particularly
applicable to boxes or surfaces that have one or more studs or pins attached to
or formed upon them, and to any system of electrical distribution. The object of
my invention is to attach the base of any electrical fitting to the stud or studs
without twisting or turning the said base, and conforming to any system as afore-
said.
In order that my invention may be the better understood I have appended the
accompanying sheet of drawings, in which Figure 1 is a plan view of the base
of a switch, cut-out, ceiling rose, or any other fitting, and Figure 2 is a sectional
elevation of the same showing its attachment to a surface according to my
invention. Similar letters of reference indicate corresponding parts throughout
the views.
In carrying out my invention, I take a china, stoneware, or other insulated
base A, with a dividing wall B, and connection plates CC, and bore this to
receive a shouldered sleeve E, Figure 2, which may screw upon the stud F on
the surface H. The shank of E is bored and screwed to receive a headed screw D
The base being placed upon the surface H, by screwing the sleeve Eupon the
stud F, it is fixed tightly by the final turn of the screw D, which presses the
base A when screwed home. When it is desired to remove the base A, the
screw D is removed entirely, and A is lifted off the sleeve E, which may then be
separately unscrewed from F, or alternatively, the screw D may be attached to
the sleeve E by soldering or the like, or by burring or extending the diameter
of its end, so that both are unscrewed together.
A connection may be established between the stud F and one of the contact
plates CC, by means of a metal plate through which the sleeve E passes when
placed in the base A, so that the pressure of the screw D makes perfect contact
at the same time that A is pressed upon the surface H. Any number of studs
or fastenings may be used, and in some cases where it is desired to substitute
a space for the insulation G, distance pieces of insulating material may used,
which being screwed upon studs attached to or formed upon the surface H as
shown by F, have other studs projecting from the top to which the base A is
attached in the manner hereinbefore described.

An Improved Method of and Means for Holding the Bases of Electrical
Fittings within Boxes or upon other Surfaces.
I, FREDERICK BATHURST, of No. 4, Limes Villas, West Hill Road, in the
County of London, S.W.; Electrical Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
My invention relate to an improved method of, and means for holding the
bases of electrical fittings within boxes or upon other surfaces, and is particu-
larly applicable to boxes or surfaces that have one or more studs adapted or
attached to or formed upon them and to any system of electrical distribution.
The object of my invention is to attach the base of any electrical fitting to the
stud or studs without twisting or turning the said base, and conforming to any
system as aforesaid. Consequently the turning or twisting the connecting wires
fastened to the contact studs on said base is obviated, and in the case of boxes
of small size, greater facility is afforded in making all connections outside said
box, together with a quick and effective method of fixing said base within the
box.
In order that my invention may be the better understood, I have appended to
my Provisional Specification the accompanying sheet of drawings, to which
reference may be had in the following description, in which Figure 1 is a plan
view of the base of a switch, cut out, ceiling rose, or any other fitting, and
Figure 2 is a sectional elevation of the same showing its attachment to a surface
according to my invention. Similar letters of reference indicate corresponding
parts throughout the views.
In carrying out my invention, I take a china, stoneware, or other insulated
base A, with a dividing wall B, and connection plates CC, and bore this to
receive a shouldered sleeve E, Figure 2, which may screw upon the stud F on
the surface H. The shank of E is bored and screwed to receive a headed screw D.
The base being fixed upon surface H, by screwing the sleeve E upon the
stud F, it is fixed tightly by the final turn of the screw D, which presses the
base A when screwed home. When it is desired to remove the base A, the
screw is removed entirely, and A is lifted off the sleeve E, which may then be
separately unscrewed from F, or alternatively, the screw D may be attached to
the sleeve E by soldering or the like, or by burring or extending the diameter
of its end, so that both are unscrewed together.
Any number of studs or fastenings may be used; and in some cases where it
is desired to substitute a space for the insulation G, distance pieces of insulating
material may be used, which being screwed upon studs attached to or formed
upon the surface H as shown by F, have other studs projecting from the top to
which the base A is attached in, the manner herein before described.
Said stud or studs may be formed either of metal or insulating material so
that in the latter instance and in the particular case in which insulating lined
metal boxes are employed, the porcelain base is fastened in the box, in order
to procure a secure fastening with a perfect insulation.
In the case of using metallic studs, the connection may be assumed to be made
through the tube of the conduit, but when the studs are of insulating material
the insulation is perfect, and no leakage due to surface moisture or the like can
occur.

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 is;-
First. In an improved method of and means for holding the bases of electrical
fittings within boxes or upon other surfaces, the construction and use of a screwed
and shouldered sleeve E engaging with a fixed stud F, made of metal or insu-
lating material, and also the screw I substantially as and for the purposes herein
described with reference to the drawings.
Second. In an improved method of, and means for holding the bases of elec-
trical fittings within boxes or upon other surfaces the construction and use of
ore or more fixed studs with screwed sleeves and set screws, in combination with
istance pieces of insulating material or substances substantially as herein
described, and shown by the drawings.
Third. In holding the bases of electrical fittings within boxes or upon other
surfaces, as referred to in the preceding claims, the method of and means for
attaching the screw D to the sleeve E by soldering or burring substantially as
herein described.
Fourth. The construction, adaptation, and use of fixed studs of metal or insu-
lating material screwed sleeves and screws substantially as and for the purposes
herein described, with reference to the appended drawings.
