page_text: I HOWARD COCHRANE JOBSON of Wolverhampton Street Dudley in the County of
Worcester Civil Engineer do hereby declare the nature of this Invention to be as
follows:-
In clips for attaching or fixing insulators to telegraph poles as ordinarily constructed
one end of each clip of the pair of clips is provided with a boss in a hole
in which the lower end of the stalk carrying the insulator or the bolt carrying or
holding the shackle straps is inserted and fixed.
In constructing a clip according to any invention I make it as usual in two halves.
I extend preferably by forging one end of the half clip so as to form a horizontal arm
the outer end of which being turned up at right angles form forms the stalk to the top
of which the insulator is affixed.
Two of the said half clips which are identical in form, and size are connected
together by screw bolts and nuts so that the stalks for receiving the insulators are
symmetrically situated on each side of the body of the clip. The two half clips are
made to grip and are thereby fixed to the telegraph pole by means of the screw bolts
and nuts described.
Although I prefer to form one stalk on the end of each half clip yet two stalks may
be formed on the ends of one half clip and the other half clip may be without a
stalk.
•
Where the clip has to support four insulators I make one of the stalks described on
each end of both of the half clips and as the distance at which one of the two wires
on each side of the pole requires to be supported is different from the distance at
which the other wire requires to be supported the pair of horizontal arms on each side
of the pole requires to be of different lengths.
To effect this one of the half clips may have short horizontal arms and the other
half clip may have long horizontal arms or each clip may have one long and one short
horizontal arm.

page_text: That part of the clip which I have described as the horizontal arm may where
necessary or desirable have a curved figure given to it and the stalk may be vertical or
at any desired angle or even remain horizontal.
I do not limit myself to any particular method of attaching the insulators to .the
stalks but I prefer to attach them by the method described in the specification of
Letters Patent granted to John Henry Cordeaux dated February 7th 1877 No. 522.
Clips made according to my invention are not liable to the defect of clips having
horizontal arms welded on the convex part or body of the clip the said welded clip
frequently breaking in consequence of defective welding.
The stalk whether vertical or horizontal can be used to attach the shackle straps to
instead of the shackle bolt the straps being placed on the stalk and secured by nuts or
other device.

Improvements in Clips for Attaching or Fixing Insulators to
Telegraph Poles.
I HOWARD COCHRANE..JOBSON of Wolverhampton Street, Dudley in the County of
Worcester, Civil Engineer, do hereby declare the nature of my Invention and in what
manner the same is to be performed to he particularly described and ascertained in
and by the following statement :-
In clips for attaching or fixing insulators to telegraph poles as ordinarily constructed
one end of each clip of the pair of clips is provided with a boss in a hole in which the
lower end of the stalk carrying the insulator or the bolt carrying or holding the
shackle straps is inserted and fixed.
In constructing a clip according to my invention I make it as usual in two halves.
I extend preferably by forging one end of the half clip so as to form a horizontal
arm the outer end of which being turned up at right angles forms the stalk to the top
of which the insulator is affixed. Two of the said half clips, which are identical in
form and size, are connected together by screw bolts and nuts so that the stalks for
receiving the insulators are symmetrically situated on each side of the body of the clip.
The two half clips are made to grip, and are thereby fixed to the telegraph pole by
means of the scrow bolts and nuts described.
Although I prefer to form one stalk on the end of each half clip yet two stalks
may be formed on the ends of one half clip and the other half clip may be without a
stalk.
Where the clip has to support four insulators I make one of the stalks described on
each end of both of the half clips and as the distance at which one of the two wires
on each side of the pole requires to be supported is different from the distance at
which the other wire requires to be supported, the horizontal arms on each side of the.
pole require to be of different lengths.
To effect this one of the half clips may have short horizontal arms and the other
half clip inay have long horizontal arms; or each clip may have one long and one
short horizontal arm.
That part of the clip which I have described as the horizontal arm may where
necessary or desirable have a curved figure given to it and the stalk may be vertical,
or at any desired angle, or even remain horizontal.
I do not limit inyself to any particular method of attaching the insulators to the
stalks but I prefer to attach them by the method described in the specification of
Letters Patent granted to John Henry Cordeaux dated February 7 1877 No. 522.
Clips made according to my invention are not liable to the defect of clips having
horizontal arins welded on the convex part or boly of the clip, the said welded clip
frequently breaking in consequence of defective welding..

page_text: The stalk whether vertical or horizontal can be used to attach the shackle straps to
instead of the shackle bolt the straps being placed on the stalk and secured by nuts or
other device.
Figure 1 of the accompanying Drawings represents in side elevation and Figure 2
in plan a clip for attaching or fixing insulators to telegraph poles, the said clip being
made of two half clips similar in form and size according to one of the arrangements
of my invention.*
The half clips which are bound upon the telegraph poleg are marked a, a, one end b
of each half clip a having fixed upon it by forging (preferably) an extension or
horizontal arm c the outer end of which is turned up at right angles to form the stalk d
to the top of which the insulator is affixed by screwing at e or is otherwise fixed to the
top of the stalk. Two of the half clips of the construction described being placed
together in the manner represented in Figure 2 they are connected together by the
screw bolts and nuts at ff, the stalks d, d being situated symmetrically on each side of
the body a, a of the clip. The same bolts and nuts at ff which are used to connect the
half clips a a together are also used for binding the half clips to the telegraph pole g
as will be understood by an examination of Figure 2.
Instead of forming the arm and stalk on one end of each half clip as just described,
the two arms and stalks may be formed on the ends of one of the half clips only, the
other half clip being without arms and stalks.
This modification of my invention is represented in side elevation in Figure 3 and
plan in Figure 4, where the two half clips are marked respectively a and a², the half
clip a being without arms and stalks and the half clip a having at each end an arm c
and stalk d. The tops of the stalks d, d in this arrangement are not screwed, but the
insulators are attached by cement to the recessed or notched upper ends of the stalks;
but the insulators. may be attached to the stalks in the arrangement Figures 3 and 4 by
screwing or otherwise.
Figure 5 represents in side elevation and Figure 6 in plan a clip constructed
according to my invention for supporting four insulators. In this arrangement both
ends of each half clip a are provided with arms, a long arm c² and a short arm c³, and
the ends of the long and short arms c², c³ of each half clip a are formed into stalks d, d
having screwed ends e to which the insulators are attached by screwing; ƒƒ are the
fixing screw bolts and nuts.
Or the modification represented in side elevation in Figure 7 and plan in Figure S
may be employed. In this modification each end of the half clip a is furnished with
a long armi c² and each end of the half clip a² with a short arm each arm having a
stalk d to the tops of which the insulators are fixed. The construction of these
modifications of my invention is best seen in the plans Figures 6 and 8.
In place of fixing insulators on the top of the vertical stalks of the clip, reels or
shackles may be fixed on the bodies of the stalks in the manner represented in side
elevation in Figure 9 and plan in Figure 10; or the stalks may be situated horizontally
as represented in Figures 13 and 14 and the reels or shackles be fixed on the said
horizontal stalks as represented; or the stalks may have the curved or inclined position
represented at the right hand end of Figures 11 and 12 and the reels or shackles be
attached to the said curved or inclined stalks.
+
Figures 11 and 12 also illustrate in part my method of attaching the shackle straps
of the shackles or reels to the arms or stalks of the clip. In the said Figures 11 and 12
the shackle straps are marked h, and are carried by the vertical stalk of the clip
is the shackle bolt carrying the reel or the shackle k. The said shackle straps hi
are fixed to the bolt by the screw nut and to the stalk by the screw nut
screwing on the top of the stalk as represented.
Instead of attaching the insulators, reels or shackles directly to the bodies of the
stalks, whether vertical inclined or horizontal, as illustrated in Figures 9, 10, 11, 12, 13
and 14, the shackle straps h (Figures 11 and 12) may be employed and attached to
the said stalks of the said arrangements as well as to the stalks of the other arrange-
ments hereinbefore described and illustrated in the accompanying Drawings in the
manner illustrated with respect to Figures 11 and 12.

page_text: Having now particularly described and ascertained the nature of my Invention
and the manner in which the same is to be performed I declare that I claim
as my invention of "Improvements in clips for attaching or fixing insulators to
telegraph poles" :—
Constructing the said clips substantially in the several ways herein before described
and illustrated in the accompanying Drawings, whereby one end of each half clip or
both ends of each half clip or both ends of one half clip is or are furnished with an
arm or arms the ends of which are formed into stalks either vertical inclined curved
or horizontal, on which stalks the insulators reels or shackles are secured or to which
the shackle straps of the reels or shackles are fixed for the purposes and substantially
as described and illustrated.
