A Self Locking or Automatic Attachment for Lamps to Vans, Carts,
Carriages, Cycles and the like.
JOHN PHILLIPS, 69, Hatton Garden, London, E.C., Lamp Maker and Hardware
Agent, and CHARLES DUNN and ALBERT VICTOR TAYLOR, Lamp Makers, both
of 61, Burbury Street, Birmingham, do hereby declare the nature of this inven-
tion to be as follows:-
-
We take a flat strip of iron, steel or other suitable substance of any required
width and bend same so that one side is parallel to the other thus making a
flat hook upon one side of which we punch a narrow vertical slit, the other
side we then fasten by rivets, solder or bolts to the side or back of any van, cart,
carriage, cycle or the like lamp. We then take what is known as an ordinary
boxed staple made of iron, steel or any suitable substance and cut in same at
either end a slit large enough to take the hook above mentioned, and in the
interior space of the boxed staple we construct a tongue of metal or any suitable
substance and upon the back of which we fasten a flat feather spring or an
We then fasten the
ordinary spiral spring or springs as may be most desirable.
boxed staple with the tongue & spring above mentioned to the side of a van,
cart, carriage, cycle or the like, and I take the lamp or lantern with the hook
attached to same as described above and pass the hook into the boxed staple
through the slits in same which we have prepared. When the slit in the hook
reaches the tongue inside the boxed staple the point of the tongue by means of
the spring or springs is automatically pressed into the slot, thus fastening same
into position upon the van, cart, carriage, cycle and the like from which it
cannot be removed without the aid of a key. To allow for the insertion of the
key we have made a small hole in the side of the boxed staple, opposite to one
end of the spindle above mentioned which end is formed to fit any shaped key
it is desired to use, the key when inserted and turned releasing the tongue
lantern can then be removed at
from the slot in the hook and the lamp or
pleasure.

JOHN PHILLIPS, Lamp Maker, 69, Hatton Garden, London, E.C., CHARLES
DUNN and ALBERT VICTOR TAYLOR, both Lamp Makers, of 61, Burbury Street,
Birmingham, 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:-
Our invention has for its object a self locking or automatic attachment for
lamps to vans carts carriages cycles and the like which is simple in action
cheap to manufacture and not liable to get out of repair.
In order that our invention may be clearly understood and easily carried
into practice we have appended hereunto a sheet of drawings upon which we
have illustrated our invention as applied to a cart lamp attachment and from
which its application to other carriages cycles and the like will be readily under-
stood.
Figure 1 is a view of the hook which is attached to the lamp.
Figure 2 is an internal view of the box staple which, is attached to the cart.
Figure 3 is a vertical section of the hook and box staple when connected and
locked together.
Figure 4 is a similar section to Figure 3 but shewing the parts unlocked.
Figure 5. is also a similar section to Figure 3 but shewing the action of the
lock in case of an attempt to withdraw the hook while the parts are locked.
Figure 6 is a part view of a key suitable for use with this lock.
In carrying our invention.into effect we provide the hook B which is formed
of any suitable metal of a shape similar to that shewn in Figure 1 and which
is provided with. the slot A and is attached at 6' to any convenient part of the
lamp Y.
For the box of the lock we utilize what is known as a boxed staple C which
is cut away at c¹ and to form a slit large enough when the box is fixed
to the cart X to receive the aforementioned hook.
Within the boxed staple C we hang the tongue plate D upon the pivots d
and provide a suitable spring E so as to project the tongue into the slot
between the box C and the cart in such a manner that when the hook B is
pressed down into the slot c¹ the end of the tongue automatically engages
with the slot A. and the hook B is locked in position as shewn at Figure 3.
:
For unlocking the hook when required for removal suitable projections such
as are provided on the tongue plate near the pivot while a suitable key
hole is provided in the casing C for the insertion of the box key G by
the turning of which key the tongue plate is twisted on its pivots until the end
of the tongue d' is free of the hook as shewn by Figure 4 but any attempt to
withdraw the hook when caught by the tongue only causes the tongue to enter
further into the slot until the shoulders and meet the hook and prevent
it being drawn further as shewn by Figure 5.
The shape of the projection 3 and 4 and the key G may be varied without
departing from our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
1st. The self locking or automatic attachments for lamps to carts and the

page_text: like characterized by the combination of a slotted hook with a box, having a
spring tongue pivoted therein, said tongue engaging with the slot in the hook
with means for unlocking the tongue from the slot substantially as and for
the purpose herein set forth and illustrated.
2nd. The self locking or automatic attachment for carts, and the like substan-
tially as and for the purpose herein set forth and illustrated.
