page_text: We, WILLIAM HENRY NICHOLS, Engineer, and W. T. HENLEY'S TELEGRAPH
WORKS COMPANY LIMITED, both of 27, Martin's Lane, Cannon Street, in the
City of London, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved clamp connection for electrical con-
ductors, particularly suited for connecting conductors of double or triple concentric
cables in what may be termed straight through disconnecting boxes, the object
being to facilitate the adjustment of the clamp in position before soldering and
to avoid the necessity of a fine fit in order to ensure perfect connection. The
clamp is made in the form of an oblong strap having fitted to slide between its
members a saddle-piece adapted to be forced inwards by a pressure screw and
of semi-circular form so as to firmly embrace between it and the oppositely curved
end of the strap the end of the cable to which it is applied, the strap also being
provided with a cone or a laterally projecting lug for attachment of a connecting.
bridge piece by which the two clamps of a pair are electrically united.

We, WILLIAM HENRY NICHOLS, Engineer, and W. T. HENLEY'S TELEGRAPH
WORKS COMPANY LIMITED, both of 27, Martin's Lane, Cannon Street, in the
City of London, 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 an improved clamp connection for electrical con-
ductors, particularly suited for connecting conductors of double or triple concentric
cables in what may be termed straight-through disconnecting boxes, the object
being to facilitate the adjustment of the clamp in position before soldering and
to avoid the necessity of a fine fit in order to ensure perfect electrical connection.
The improved clamp will be described with reference to the accompanying draw-
ings forming part of this specification wherein Figure 1 is an end view, Figure 2
a plan, and Figure 3 a part longitudinal section of the clamp.
The clamp is made in the form of an oblong loop or strap A having fitted to
slide between its members a saddle piece B adapted to be forced inwards by a

page_text: pressure screw C the saddle piece being of semi-circular form as shewn in
Figure 1, so as to firmly embrace between it and the oppositely curved end a of
the strap the end of the cable to which it is applied, the strap also being provided
with a cone or a laterally projecting lug A' having holes tapped in it to receive
the bolts for the attachment of a connecting bridge piece D by which two similar
clamps constituting a pair are united in order to electrically connect the corre-
sponding conductors of the two portions of cable to be joined together. The
saddle piece B is provided with through holes 6 leading from the back of the saddle
piece to the inner surface and the back or upper side is formed as a cup b¹ to
receive the solder which is conducted by the holes to the surfaces to be soldered
to the cable conductor.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
-
The herein described combined screw clamp and soldered connection for electri-
cal conductors substantially as specified.
