Improvements in Means for Securing Lamps and other Articles to
Walls, Posts, or other Supports.
I, ELI HENRY GRIFFITHS of 102 Bradford Street Birmingham, Lamp.
Manufacturer do hereby declare the nature of this invention to be as follows:-
Many lamps and other articles are made to rest in required positions, by means
of a metal tongue, fixed on the back of the lamp, and resting in a loop secured to
a wall or other support.
My invention consists in placing a spring latch on the inside of the lamp,
projecting through the back of the lamp, behind the tongue, and passing through a
hole in the loop, when the lamp is placed in position. By this means the lamp is
held in its fixings, and cannot be removed until the spring latch, inside the lamp is
withdrawn.
The spring latch which projects through the loop, is tapered on the lower side,
so that when placing the lamp, in required position the spring allows. the latch to
recede and to lock automatically into a hole in the loop.
The loop instead of the tongue may be attached to the lamp if required, in this
case, the spring latch would lock into a hole in the tongue.
Dated this Third day of January 1895.
Improvements in Means for Securing Lamps and other Articles to
Walls, Posts, or other Supports.
I, ELI HENRY GRIFFITHS, of 102 Bradford Street, in the City of
Birmingham, Lamp Manufacturer 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 for securing lamps and other articles, such, for
example, as clocks, smokers cabinets, supporting brackets, electrical wall
instruments and the like, to walls, partitions, standards and like supports, and
consists in the employment of a lock combined with means for the infibulation of
the locking parts.
According to my improvements, the fastener is provided with a spring latch,
suitably fitted within the inside of the article, and with the free end having an
inclined headed catch, which normally passes through an opening in the back of
the article and is hooded over by a spring tongue. When connection is made
between the article and its support, the inclined headed latch snaps through an
opening in a fixed attachment plate sunken about its middle for receiving the
tongue of the other part.

page_text: Figure of the accompanying drawings represents partly in vertical section and
partly in elevation, my new or improved securing means applied to a wall lamp;
which is shown secured to a wall or other support.
Figure 2 represents a like view as Figure 1, but with the lamp shown in the act
of being connected to the fixed bracket support.
Figure 3 is a transverse section upon the dotted lines - Figure 1.
Figure 4 is a back elevation of the lamp, whilst Figure 5 is a like view, but
showing, in addition, the attachment or wall plate, within the recess in which the
tongue of the lamp engages.
Figure 6 is a front elevation of the wall-plate ouly.
Figure 7 is an elevation of the latch mechanism as seen from the inside of the
lamp, showing the thumb lever for taking the latch from engagement with the wall
plate on the said lamp requiring to be moved.
a is the lamp, having fitted to the inside back a¹, thereof, a spring latch b,
consisting of a flat strip of spring metal b', made fast at its lower end b, and having
at its upper and free end a chisel-ended catch or head 63, having its underside 6*,
inclined or bevelled & with the said end extending, by the force of the spring
limb, through an opening a², in the back a', of the lamp, and with the said catch b³,
coming within the space, immediately hooded over by a cranked and depending
tongue a³, made fast to the back of the lamp.
c is an attachment plate, secured to a wall, standard or other upright d, and
having at its middle, an all-through piercing c¹, formed in the centre of a
depressed part 2, into which latter, the tongue a³, takes and wherein it lies flush.
Situated on the inside of the lamp is an arm e, working within brackets or
bearings e', and having at one end a cranked part e, coming under the head end b³,
of the spring latch 6, whilst the other end is outwardly cranked at e³, and is
terminated by a pusher or button e.
Normally the spring plate 61, of the spring latch b, keeps the parts in the
positions represented in Figure 1, so that when the tongue a³, is brought at the
back, and into the recess, of the attachment plate, the inclined plane of the chisel
end, strikes against the front top edge c³, of the said attachment plate, and is
then forced back, and immediately the said end comes opposite the hole c', it snaps
into it, and thereby locks the lamp to its fixings.
To unfasten the catch for releasing the lamp, press the button e, when the arme,
is rotated and the cranked end e, made to turn inwards, force the latch backwards
and take its catch end 3, out of the range of the hole or piercing c', and so release
the lamp from the attachment plate.
I wish it to be understood that instead of employing the arm e, a button or pull
may be attached to the latch and employed for the same purpose.
The application of my invention to affixing clocks, cabinets, brackets,
instruments and the like to walls, standards and other supports, differs in no
essential respect from its application to the affixing of a lamp to a wall as herein
described.
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. Means for securing lamps and the like to their supports, consisting of a
spring limb, with a catch end taking through a hole in the back of the lamp or like
article, and engaging with an attachment bracket secured to a wall or other
support, substantially as described and set forth.
Secondly. Means for securing lamps and the like to their supports, consisting of
a spring limb, with a catch end taking through a hole in the back of the lamp or
like article, which said back carries a depending and cranked tongue, which, with
the catch end, engages with an attachment plate sunken about its middle and
having a piercing in its centre, substantially as described and set forth.

page_text: Thirdly. The combination with the means herein described for locking or
securing a lamp or other article to a wall or like support, of a catch releasing arm,
substantially as described and set forth.
Dated the 16th day of August 1895.
