Improvements in the Connections of the Parts of Earthenware
Articles employed in connection with Electrical Switches,
Cut-outs, Ceiling Roses, and the like.
We, THOMAS TAYLOR and WILLIAM TUNNICLIFF, trading as Taylor,
Tunnicliff and Company, of Eastwood, Hanley, in the County of Stafford,
Manufacturing Potters do hereby declare the nature of this invention to be as
follows:
This invention relates to means of connecting or coupling together the earthenware
parts employed in connection with electrical switches, cut-outs, ceiling roses and
the like.
Thus, in such earthenware articles, the base part has to be connected or coupled
to the cover part, and it is in this connection or union that our invention resides.
Heretofore, the connection of one part to a second part in such earthenware
articles, has been performed by he and she screw 'threads being formed within the
earthenware articles themselves, and with the one taking directly into the other,
without the employment of any intervening medium. On the firing of the said
articles during manufacture, the same are liable to be slightly distorted in figure
consequent upon contraction, hence a liability of the screwed parts to vary in size,
and when in usc, such faults admit of the said parts becoming loose or uncoupled,
consequent upon vibration.
By our invention, the base and the cover of such earthenware articles are coupled
together by inside and outside metallic intervening attachments in the form of rings
or annuluses screwed inside and outside respectively, and with one of the said
attachments fitted circumferentially around a neck of the base part, and the other
fitted circumferentially within the mouth of the cover part, so that by screwing the
attachments together, a coupling of the two part earthenware articles is thereby
performed.
In carrying out one form of our invention, in connection with a switch, cut-out or
ceiling rose, we take an inside screwed ring, annulus, or collar, and fit the same, by
cement or otherwise, within the mouth, or within the entrance to the mouth of the
earthenware cover part. We then take a second and outside screwed and top inside
flanged ring, suitable for taking into the inside screwed attachment of the other
part, and fit the same upon, and circumferentially around, a table-collar directed
from the top side of the earthenware base part.
The affixing of the metal attachment is performed either by cement or
otherwise.
By connecting the said two part earthenware articles together by fitted metal
connections, a more perfect hold or connection between the said parts, is insured,
without the liability of the same to work loose when subjected to vibration.
Instead of the said metallic attachments or junctions being fastened by cement,
they may be affixed by rolling or burnishing a portion of the metal of the boundary
edge over a portion of the earthenware part.
In carrying out our invention in connection with a tumbler or other switch, where
the connection is made in the centre of the cover instead of the outer circle, and the
cover is in shape alike unto an inverted half hemisphere, and is provided with a
hole through the middle of the crown and which hole we bush or fit with a inside
screwed metal ring, whose top and bottom edges are flanged, and are rolled, turned
or burnished over the top and inside boundary edges of the said crown hole, hen c
the affixing of the same in position.

page_text: The base is fitted upon its top with the ordinary metallic bridge or bracket, with
outwardly directed feet or flanges connected to the said earthenware, base part by
small screws directed through holes in the said base.
Proceeding upwardly from the bridge, or middle of the top of the bracket, is a
short screwed neck, adapted to take within the bushed fitting or attachment of the
other part, hence the connection of the cover to the base, which latter is provided
with the parts common to this class of switch.
The application of our invention to other two, three or more part earthenware
electrical articles, differs in no essential respect from its application to switches,
cut-outs, roses and the like, as hereinbefore described.

Improvements in the Connections of the Parts of Earthenware
Articles employed in connection with Electrical Switches,
Cut-outs, Ceiling Roses, and the like
We, THOMAS TAYLOR and WILLIAM TUNNICLIFF, trading as Taylor,
Tunnicliff and Company, of Eastwood, Hanley, in the County of Stafford,
Manufacturing Potters, 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 means of connecting or coupling together the
earthenware parts employed in connection with electrical switches, cut-outs, ceiling
roses, and the like.
Thus, in such earthenware articles, the base part has to be connected or coupled
to the cover part, and it is in this connection or union that our invention resides.
Heretofore, the connection of one part to a second part in such earthenware
articles, has been performed by he and she screw threads being formed within the
earthenware articles themselves, and with the one taking directly into the other,
without the employment of any intervening medium.
On the firing of the said articles during manufacture, the same are liable to be
slightly distorted in figure consequent upon contraction, hence a liability of the
screwed parts to vary in size, and when in use, such faults admit of the said parts
becoming loose or uncoupled consequent upon vibration.
By our invention, the base and the cover of such earthenware articles are coupled
together by inside and outside metallic intervening attachments in the form of rings
or annuluses screwed inside and outside respectively, and with one of the said
attachments fitted circumferentially around a neck of the base part, and the other
fitted circumferentially within the mouth of the cover part, so that by screwing the
attachments together, a coupling of the two part earthenware articles is thereby
performed.
In carrying out one form of our invention in connection with a switch, cut-out or
ceiling rose, we take an inside screwed ring, annulus or collar, and fit the same, by
cement or otherwise, within the mouth, or within the entrance to the mouth of the
earthenware cover part. We then take a second and outside screwed and top inside
flanged ring, suitable for taking into the inside screwed attachment of the other
part, and fit the same upon, and circumferentially around, a table collar directed
from the middle of the top side of the earthenware base part.
The affixing of the metal attachment is performed either by cement or otherwise:
By connecting the said two part earthenware articles together by fitted metal

page_text: connections, a more perfect hold or connection between the said parts is ensured,
without the liability of the same to work loose when subjected to vibration.
Instead of the said metallic attachments or junctions being fastened by cement,
they may be affixed by rolling or burnishing a portion of the metal of the boundary
edge over a portion of the earthenware part.
In carrying out our invention in connection with a tumbler or other switch, where
the connection is made in the centre of the cover instead of the outer circle, the
cover is in shape alike unto an inverted half hemisphere and is provided with a hole
through the middle of the crown, and which hole we bush or fit with an inside
screwed metal ring, whose top and bottom edges are flanged, and are rolled, turned
or burnished over the top and inside boundary edges of the said crown hole, hence
the affixing of the same in position.
The base is fitted upon its top with the ordinary metallic bridge or bracket, with
outwardly directed feet or flanges connected to the said earthenware base part by
small screws directed through holes in the said base.
Proceeding upwardly from the bridge or middle of the top of the bracket, is a
short screwed neck, adapted to take within the bushed fitting or attachment of the
other part, hence the connection of the cover to the base, which latter is provided
with the parts common to this class of switch.
The application of our invention to other two, three or more part earthenware
electrical articles, differs in no essential respect from its application to switches,
cut-outs, roses and the like, as hereinbefore described.
Figure 1 of the accompanying drawing represents in perspective and vertical
section, the cover part of a switch, cut-out or ceiling rose provided with a metallic
fitting made according to our invention.
Figure 2 represents in perspective and in elevation, the inetallic fitting of the
cover part Figure 1.
Figure 3 represents in vertical section the base of a switch, cut-out or ceiling rose
provided with a metallic fitting made according to our invention, and Figure 4
represents the parts separately.
In Figures 1 and 2, a is an inside-screwed ring, annulus or collar, fitted by cement
or otherwise within the mouth or within the entrance &', of the earthenware cover
part b.
In Figures 3 and 4, c is an outside screwed ring, fitted upon a collar d³, of an
earthenware base part d, and adapted to take within the inside screwed part a, of
the cover b.
Figure 5 represents in elevation, the cover of a tumbler switch, provided or fitted
with improvements made according to my invention.
Figure 6 is a sectional and perspective view of the same.
Figure 7 is the base part of the same fitted with the ordinary metallic bridge or
bracket.
In Figures 5 and 6, a is the metallic fitting, fitted within the crown piercing 2,
of the earthenware cover b.
In Figure 7, d is the earthenware base, d' the metallic bridge or bracket, having
upon its top side, a metallic and outside screwed neck c, which takes within the
inside screwed bush or collar a.
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:
First-
In switches, cut-outs, ceiling roses and the like, affixing the covers or
like earthenware parts of the one part, to the earthenware bases or like parts of the
other part, by fitted metallic fittings, attachments or connections a and c, taking one
within the other or one over the other, substantially as and for the purpose as
described and set forth in Figures 1 to 4.
Secondly tumbler switches and the like, affixing the covers or like
earthenware parts of the one part, to the earthenware bases or like parts of the

page_text: other part, by fitted metallic fittings, attachments or connections a and c, taking one
within the other or one over' the other, substantially as and for the purpose as
described and set forth in Figures 5, 6 and 7.
