Complete Specification Left, 9th Dec., 1896-Accepted, 23rd Jan., 1897
1, THOMAS SANDERS, St. Mary's Street, Ladywood, Birmingham, in the
County of Warwick, Brass Founder, do hereby declare the nature of my said
invention to be as follows:-
My invention has for its object improvements in electric bell pushes or knobs, by
which the twisting off or disconnection of the button or push from the circuit
wire which often happens with the round push as at present constructed is
prevented.
In carrying my invention into practice, I form the button, knob or push which
is pressed when the electric bell is rung, either square, oval oblong or any shape,
out of wood, porcelain, brass or other material which will prevent the same from
turning round in the socket or hole in the mount and this socket or hole is made to
correspond with the shape of the knob or push.
By making electric bell pushes or knobs so that they cannot turn in their sockets
the indication word is always maintained in the proper position and I prevent
them from being twisted off there connections which is a source of great
inconvenience.

1, THOMAS SANDERS of St. Mary Street, Ladywood, Birmingham, in the
County of Warwick, Brass Founder, do hereby declare the nature of my said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has for its object improvements in electric bell pushes or knobs
by which the twisting off or disconnection of the button or push from its circuit
wire which often happens with the round push as at present constructed is
prevented.
In carrying my invention into practice I form the bottom knob or push which
is pressed when the electric bell is rung either square, oval, oblong or any shape
out of wood, porcelain, brass or other material which will prevent the same from
turning round in the socket or hole in the mount and this socket or hole is made to
correspond with the shape of the knob or push.
By making electric bell pushes or knobs so that they cannot turn in their sockets
the indication word is always maintained in its proper position and I prevent
them from being twisted off their connections which is a source of great
inconvenience.

page_text: In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a sheet of drawings showing my
invention applied in regard to three shapes, square, round ended, oblong and
hexagonal but it must be clearly understood that I may make the pushes heart
shape, or even round with recesses in the side or projections thereon so long as the
alteration from round is sufficient to prevent the push from turning.
It will also be understood that the design may be varied greatly without departing
from the invention.
Figure 1 is a side elevation showing a square push P mounted in position.
Figure 2 is a plan view of Figure 1.
Figure 3 is a side elevation of the push P taken out of the mount, and
Figure 4 is a plan of the same.
Figure 5 is a side elevation of a differently designed mount with a round ended
oblong push P in its normal position.
Figure 6 is a plan of Figure 5.
Figures 7 and 8 are elevation and plan of the oblong push P taken out of the
mount.
Figure 9 is an elevation similar to Figure 5 and with the same oblong push P
but part of the side of the casing E is broken away to show the base p¹ of the
push in position.
Figures 10 & 11 are side elevation and plan of a hexagonal push but the push
may be made just as well octagonal or other polygonal figure.
The push P as shown in Figures 1, 2, 5, 6, and 9 is mounted in the usual
casing E and upon the base B and operates as usual upon the spring S to make
contact when the push P carries the spring inwards.
Now according to my invention the push P is made square as seen at Figs. 1, 2, 3
and 4 or oblong as seen at Figures 5, 6, 7, 8 and 9 or hexagonal as seen at
Figures 10 and 11 or it may be made the shape of a shield or heart or diamond or
octagon or other polygonal shape or even round with a groove or grooves or
projection or projections upon the side so long as the shape prevents the push from
turning round. The crown e¹ of the mount casing E is of course pierced with a
hole corresponding with the push or knob P.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improvements in electric bell pushes or knobs and their mounts consisting
of a push such as P which in plan is either square, oblong, polygonal or other
equivalent shape with the crown of the mount pierced to correspond therewith
as and for the purpose herein set forth and as shown upon the accompanying
drawings.
