PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Certain Kinds of Attachment
Sockets for Cycle Lamps.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, Managing
Directors of. H. Miller and Company Limited, of Miller Street, in the City of
Birmingham, Lamp Manufacturers, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the manufacture of attachment sockets for cycle lamps
of the traversing clip type described in the Specification of Letters Patent granted
to Phillips and bearing date the 24th day of October 1884 and numbered 14079,
and has for its object the reduction of the cost of manufacture of such sockets and
the making of the same both light and strong by employing principally sheet metal
in their construction.
In carrying out our improvements, we take a cruciform shaped blank, which.
forms both the socket' and its strap, whose ends are formed into sleeves, barrels or
sockets for the connection to them of the arms of the compensating back. The.
vertical arms of the blank form the strap and the horizontal arms or branches are
turned forward and inwards at a distance from the strap and their meeting ends or
edges are infibulated together or creased together, thereby forming an open-ended
socket. The back part of the socket has a cruciform shaped piercing made in its
walls wherethrough a gripping slide, consisting of a U-shaped piece of metal of the
breadth of the inside of the socket, is capable of being introduced into the inside.
The back of this slide has attached to it a screw box turned up and made from a
blank of sheet metal and with ears formed at the edges taking through a hole in
the back of the slide and being there rivetted or clenched from the inside. The
screw box is wormed and a traversing screw is fitted therein.

In introducing the slide, which contracts the rubber lining of the socket around
the lamp bracket tongue, first hook the same through the vertical part of the
cruciform piercing and thread it forward when the slide passes into the interior of
the socket, with the screw box lying in the longitudinal part of the gap.
tubular cap is then dropped over the screw box, with the outer end of the screw
passing into a bearing hole in the same, whilst the forward end of the said cap
conies behind the head of the screw and is soldered in place.
By the rotation of the screw the clip is propelled or repelled, and the whole of
the parts of the socket are put together without the employment of solder other
than in securing the cap or cover of the screw box in place.

Sockets for Cycle Lamps.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, Managing
Directors of H. Miller and Company Limited, of Miller Street, in the City of
Birmingham, Lamp Manufacturers, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly describe and
ascertained in and by the following statement :-
This invention relates to the manufacture of attachment sockets for cycle lamps
of the traversing clip type described in the Specification of Letters Patent granted
to Phillips and bearing date the 24th day of October 1884 and numbered 14079,
and has for its object, the reduction of the cost of manufacture of such sockets and
the making of the same both light and strong by employing principally sheet metal
in their construction.
Figure 1 of the accompanying drawing represents a back elevation of a lamp
socket constructed according to our improvements, and Figure 2 is a front elevation
of the same.
Figure 3 is a vertical section of Figure 1 upon the dotted line ...
Figure 4 is a like view as Figure 2, but with the cap enclosing the clip-traversing
screw, and the screw box of the said clip shown in section as upon the dotted
line 2, Figure 3, the traversing screw.itself being left in elevation.
Figure 5 is a topside plan of Figure 2..
Figure 6 is the cruciform shaped, blank from which the socket is fashioned, and
Figure 7 shows a back elevation and Figure 8 a vertical section of the skeleton
socket into which the said blank Figure 6 is fashioned.
Figure 9 is an elevation of the traversing screw separately.
Figure 10 shows a section and separate end views of the cap wherein the
traversing screw works.
Figure 11 shows an edge view, an elevation and two sectional views of the
traversing clip.
Figure 12 shows a back and a front elevation, an edge view and, a plan of the said.
clip, before,the clipping plate is bent over into a U or hook figure.
Figure 13 represents an elevation and edge views of the detachable key by
which the said traversing screw is rotated.
Figure 14 shows the blank from which the screw box is made and Figure 15.the
blank or plate out of which the traversing screw is fashioned.
In carrying out our improvements we take a cruciform shaped blank a', which
forms both the socket a, and its strap. a², whose ends are formed into sleeves or
barrels a³, for the connection to them of the arms of the compensating, spring or
other back. The body part a', and vertical arms as, of the blank form the strap
and its sleeves, whilst the horizontal arms or branches a,,are turned forward and
inwards at a distance from the strap and their meeting ends or edges a, are
infibulated together or creased together at a%, thereby forming the open-ended
socket a. The back part of the socket has a cruciform shaped piercing 6, made in
its walls, through the vertical arms or parts 6, of which, the gripping slide c,
consisting of a U-shaped piece of metal c', of the breadth of the inside of the
socket, is capable of being introduced into the inside of the said socket, whilst
the other branches. 62 form a race for the screw box of the clip, as hereinafter
described, to work within. The back of this slide has attached to it a screw
box d, turned up and made from a blank of sheet metal and with ears d', formed
at the edges taking through a hole c³, in the back of the slide and being there

page_text: rivetted or clenched from the inside. The screw box is inside wormed at d² and
a traversing screw e, having a turning head el, is fitted therein.
In introducing the slide, which contracts the rubber lining of the socket
around the lamp bracket tongne, first hook the same through the vertical part
of the cruciforin piercing and thread it forward when the slide passes into the
interior of the socket, with the screw box lying coincident with the longitudinal
part of the gap. A semi tubular carrier or cap is then dropped over the
screw box, with the outer end e, of the screw passing into a bearing hole f¹,
in the same, whilst the forward and gapped end 2, of the said cap takes over
a neck, behind the head of the screw and is soldered in place. This cap
confines and forms a carrier for the screw aud allows the same to freely swivel,
and also conceals the said screw from view.
By the rotation of the screw the clip is propelled or repelled, and the whole.
of the parts of the socket are put together without the employment of solder
other than in securing the cap or cover of the screw box in place.
It is understood that the screw is passed into the screw box d, prior to the
cap, being placed in position and soldered or otherwise made fast, and that
the traversing clip is made from a flat piece of metal c, (see Figure 12), fashioned.
into the figure of a hooked clip, subsequent to the attachment of the screw-box
thereto.
Figure 16 represents a modified form of the cap of the clip-traversing screw.
This cap is in the form of a well or sinking made or shaped from out of the
metal of the back strap of the socket.
Figure 17 represents a cross section of the said socket, upon the dotted line,
Figure 16, but with the traversing screw and screw box removed, and Figure 18
represents a complete section upon the dotted line 2, Figure 16, but with the
front walls of the socket opened so as to admit of the introduction of the clip
screw box into the cap.
In Figures 16 to 18, a is the socket, the cap made in one piece with it by
a sinking process, c is the traversing clip and d is its screw box, wherethrough
the traversing screw e, passes, with its ends passing through holes f, f, in the
ends of the said cap, and with the head e', forming a shoulder coming upon the
outside of an end of the cap. a are the arms or wings which form the front
of the socket,' and 3 is a collar threaded upon and affixed to the stem of the
traversing screw and coming upon the inside of the end f³, of the cap f..
To put the parts together, first drop the clip c, into position, with the collar e³,
coincident with the hole 3, in the cap end f, then pass the screw pin e, into
position and make the collar fast to it by soldering, closing or otherwise. Now
close down the front flaps a, and joint their meeting edges as represented in dotted
lines in Figure 18, when the socket is complete.
The screw pin can now swivel in the screw box and give a traversing movement
to the clip.
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 the sockets of cycle lamps, making the same, with their back-straps,
and with or without the back strap sleeves or barrels, from a single cruciform-
shaped blank of sheet metal, such as represented in Figure 6, having a cruciform
shaped piercing in its middle, for the purpose herein described.
Secondly. In the sockets of cycle lamps, providing the back of the socket strap
with a cruciform shaped piercing, the vertical brauches of which are for the purpose
of introducing the traversing clip into the interior of the socket, whilst the other
branches constitute a race for the screw box of the traversing clip to slide or work
within on the rotation of the swivelling screw, as set forth in Figures 1 to 15.
Thirdly. In the sockets of cycle lamps, making the traversing clip from sheet
metal and providing the same with a screw box, likewise made from sheet metal,

page_text: and attached thereto by ears on the one part taking through a hole in the other
part and then being clinched, substantially as described and set forth in Figures 1
to 15.
Fourthly. In the sockets of cycle lamps, providing the same with a cap or
carrier which forms a bracket or bearing for the clip-traversing screw to work
within and a cover for concealing the same from view, substantially as described
and set forth in Figures 1 to 15.
Fifthly. In the clip-traversing screws of cycle lamp sockets, forming the same
with a neck wherein the edge of a hole in the end of the cap engages in order to
admit of the screw swivelling therein without being withdrawn, substantially as
described and set forth in Figures 1 to 15.
Sixthly. In the sockets of cycle lamps, making the cap or cover for the screw pin
from out of the metal of the back of the socket, substantially as described and set
forth in Figures 16, 17 and 18.
Seventhly. In the sockets of cycle lamps, the construction and arrangement of
the parts or means for preventing the withdrawal of the screw pin whilst admitting
of the same swivelling, substantially as described and set forth in Figures 16, 17
.and 18.
