PROVISIONAL SPECIFICATION,
An Improved Frame or Holder for Detachable Electric Fuses.
We, THE ACME & MISCH ELECTRIC WORKS, LIMITED, and ERNEST
FRANCIS MOY, Electrical Engineer, both of Ferdinand Street, Chalk Farm, NW,
in the County of London, do hereby declare the nature of this invention to 'be
as follows:-
The invention relates to an improved frame or holder for detachable electric
fuses, and it consists of porcelain or glass, moulded to receive at each end a metal
contact making, piece, and adapted by means of a single, screw (or equivalent
fastening) to hold the said contact piece securely in position. By moulding a
suitably formed recess, or projection, or both, at each end of the frame or holder
to receive a correspondingly shaped contact piece, and securing, the same in place
by the aforesaid screw, the contact piece is kept locked in its required position,
and therefore is not liable to work loose. We sometimes mould threaded holes
in the porcelain holders, thus adapting them to receive the above named screws.
when it is desired to avoid the use of a metal nut.
The fuse is secured between the ends of the holders by nipping or otherwise
securing them to a suitable part of each contact piece, or by clamping, the fuse
between the contact pieces and the holder, as the case may be. The improved
holder is preferably made of an ornamental, form, and conveniently shaped in its
central part to be grasped by the fingers. Apart from their, moulded form, the
materials used are pleasant to the eye, and are not so liable to be soiled by dirty
fingers as the wood! holders in common, use, which soon become unsightly. The
improved holders, therefore, give an improved and finished appearance to the
distribution boards on which they are mounted.

Reference is made to the accompanying drawings which illustrate the invention.
In these, Fig. 1 is an elevation of the frame or holder a, to which a metal contact
piece b is secured at each end of the holder by means of a screw c.
piece is let into a moulded recess at the ends of the holder which recess is
shown in the cross section at that part by Fig. 2; while Fig. 3 is a cross section
through the central part of the holder, and shows a moulded rib serving as a grip
for the fingers. The fuse wire d is secured between the contacts b, b, in any
convenient manner, and 'these contacts are inserted between the spring terminals of
a fuse block, shown by the perspective drawing Fig. 4.
Having now particularly described and ascertained the nature of our snid inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is ;-
An improved frame or holder for detachable electric fuses, consisting of a
moulded porcelain or glass holder a, having a metal contact piece b secured within
a moulded recess at each end by a screw c, and an electric fuse d between the said
contacts, as and for the purpose herein described and shown by the drawings.
