PROVISIONAL SPECIFICATION.
Improved Overhead Electrical Wire Holder.
FREDERICK FOY, 39, Piercy Street, Duke Street, Lower Broughton, Manchester,
Sheet Metal Worker, do hereby declare the nature of this invention to be as
follows:-
The holder consists of the socket C, & the clip bolt B. These can be made
of brass or any other suitable material.
A is the electrical wire looped on to bolt B & placed in the socket C, & drawn
up tight by the nut D.

Improved Overhead Electrical Wire Holder.
I, FREDERICK Foy, of 39, Piercy Street, Duke Street, Lower Broughton, Man-
chester, Sheet Metal Worker, 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 holders for overhead wires, such as ears for trolley
wires and the like, and the object of the invention is to provide an efficient
mechanical holder to which the wire may be attached without the use of solder.
I have illustrated my invention in the accompanying drawings, in which:-
Figs. I, II and III represent a holder or ear by means of which the trolley
wire is supported at suitable intervals. Fig. I being an elevation, Fig. II a
longitudinal medial section, and Fig. III a transverse section; Figs. IV, V
and VI represent a modification of the holder by means of which two lengths
of the trolley wire are connected as well as supported, the views being analogous
to Figs. I, II and III; Figs. VII to XII represent a modification of the holder
known as a section insulator, by means of which two lengths of trolley wire
are supported and mechanically connected, but electrically insulated from
each other, Fig. VII being an elevation; Fig. VIII a longitudinal medial section,
Fig. IX a plan, Figs. X and ✗I transverse sections respectively on A, A,
and B, B, of Fig. VII, and Fig. XII a fragmentary section on C, C, of Fig. VIII;
Figs. XIII, XIV, XV and XVI represent a modification of the holder when it
is adapted to support two wires which cross each other, Fig. XIII being an
elevation viewed in the direction of the arrow I (Fig. XV), Fig. XIV an eleva-
tion viewed in the direction of the arrow E (Fig. XV), Fig. XV an inverted plan,
and Fig. XVI an isometric view.

page_text: Throughout the drawings similar parts are indicated by the same reference
letters.
a is the wire to be supported; b is the socket, c the clip bolt, the screwed
end of which enters a clearance hole in the socket in which it is secured by
the nut d; a portion of the said screwed end projects beyond the nut and forms
the attachment to the insulator which may be of any suitable type and which
therefore it has not been considered necessary to illustrate.
Where
The socket consists of a single casting or stamping (except of course where
two wires have to be insulated from each other as in Figs. VII to XII) having
a groove formed at the ends of its underside adapted to locate the wire.
the wire is continuous as in Figs. I to III the clip bolt c is formed with an
extended hooked extremity, as shown, over which the wire is looped and by
means of which the wire is maintained in position in the grooves of the socket.
Where two wires cross each other, the socket bis duplicated as shown in Figs.
XIII to XVI, and of course the hooked extremities of the clip bolt c are likewise
duplicated the configurations of the hooked portions being such that, as indicated
in the said figures, the one wire is carried over the other; the central parts
of the hooked portions are cut away (as clearly indicated in the inverted plan
view) so that the trolley wheel may pass along either wire; in order to prevent
the trolley wheel rising in the gap so formed, and so being set into vibration,
projecting tongue pieces e may be formed with which the Hange of the trolley.
wheel engages as the wheel comes under the gap and which thus prevent the
wheel lifting. It will be noticed that the trolley wire is, in each case, locally
bent where it passes over the hooked portion of the clip bolt.
Where the holder has to connect two lengths of the trolley wire it is modified
as shown in Figs. IV to VI. The extremities of the underside of the socket b
are, as before, grooved and the ends of the wires are hooked back through
reversely set holes as indicated. The clip bolts c are not hooked, as before, but
the upper edges which bear against the wires are grooved and they are so shaped
that when they are drawn up into the socket they wedge the wires firmly in
position. Where the two wires have to be electrically insulated as in Figs. VII
to XII, the socket bis made in halves coupled together, with an interposed
insulating strip f, by means of insulated bolts. In this construction there are
preferably two clip bolts c which with the insulating strut g act as the one clip
described in reference to Figs. IV to VI. The strut g is dovetailed into the socket
and its ends are recessed so as to engage with the heels of the clip bolts cas
shown clearly in Fig. XII.
It will be noted, in each of the examples illustrated, that the clip bolts engage
with the underside of the wires and hold them up against the undersides of
the sockets, and that the lower portions of the clip bolts serve to maintain,
where the wires are bent up, the general level of the underside of the wire,
thus preventing the collector following the bent portions of the wire.
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:
1. The improved overhead electrical wire holder which comprises a socket
against the underside of which the top of the wire bears, and a clip bolt which
engages the underside of the wire, the wire being bent upwardly where it
engages with the clip bolt and the latter being adapted to hold the wire in contact
with the socket and to preserve, where the wire is bent up, the general level
of the underside thereof; substantially as described and illustrated.
2. The improved overhead electrical wire holder comprising a socket such
as b. a clip bolt such as housed within a recess in the socket and having a
screwed end by which it is drawn up into the socket and by means of which
it is connected to the insulator, substantially as described and illustrated.
3. The improved overhead electrical wire holder comprising a socket such

page_text: as b, and a clip bolt such as c, housed within the socket and having an elongated
hook-shaped head over which the wire passes, the lower portion of which head
preserves the general level of the underside of the wire; substantially as described
and illustrated.
4. The improved overhead electrical wire holder comprising a socket such
as into which the ends of the wires are turned and a clip bolt such as c housed
within the socket and adapted to draw the ends of the wire into engagement
with the socket and to preserve the general level of the underside of the wire;
substantially as described and illustrated.
