PROVISIONAL SPECIFICATION.
Improvements in Hooks and their Attachments, suitable for Signal
Flags, and for Joining Chains, Ropes, Harness Straps, and other
analogous Parts.
We, EDWARD FITZMAURICE INGLEFIELD, Lieutenant Royal Navy, late of
H.M.S. "Victoria," and ARTHUR DAVIS, a member of the firm of John Davis
& Son, Manufacturers of Mining Instruments and Electrical Engineers, of
118 Newgate Street, in the County of London, and All Saints Works, Derby,
in the County of Derby, do hereby declare the nature of this invention to be
as follows:-
The present invention relates to improvements on the invention described in the
Specification of the prior Patent No. 14633 dated 16th Sept. 1890 granted to the
above named Edward Fitzmaurice Inglefield.
The invention described in the Specification of the above mentioned Patent
consists broadly in two clips or attachments, one of which is connected to or
forms part of one of each of the parts which it is desired to connect
together, in such a way that while same are not liable to become accidentally- dis-
connected, they may be readily disengaged, by bringing the two clips into a certain
position in relation to each other, when desired.
For this purpose each clip has a portion which is cut away and formed with
pointed ends, the two clips being connected and disconnected by bringing the cut..
away portions opposite each other, and in a position at right angles to each other,
so that one clip or link will slip over the other.
According to the present invention instead of actually separating the metal or
other material at the cut-away portion, we propose leaving the pointed ends of one
of such clips connected together, and forming the space between the ends of the
cut-away portion of the other clip sufficiently large to pass over the portion
connecting the pointed ends of the first clip.
A further modification consists in varying the form of the parts of the clips
which permit the latter to be engaged and disengaged at will; and for this purpose
instead of forming such parts with "pointed" ends we make same of a curved,
convex, or irregular form on one clip, and of an opposite curve or form on the other
clip, so that one part will form a counterpart of the other, and, when the clips are
brought into the required relative positions with regard to each other, will permit
of one clip slipping over the other, so as to engage or disengage same when required.
It will be readily understood that, in this arrangement also, the ends of the parts
by means of which the two clips are engaged and disengaged, may in both clips be
separated by a small space (as in the arrangement described in the Specification of
Patent No. 14633, A.D. 1890, above referred to), or the ends of one clip only may
be so separated, while the ends of the other clip may be connected together.
The cut-away portions of the two clips may be so arranged as to enable the two
clips to be engaged and disengaged at any angle in relation to each other, which
may be found most advisable or convenient in practice, according to the particular
or special requirements of any given application.
The invention (either in the form described in the Specification of the prior Patent
above referred to, or constructed according to the different modifications thereof
described in the present Specification), is specially applicable for use in "bending"
flags together for the purpose of signalling on board ships, and also generally for
joining chains, ropes, harness straps, or other parts which are required to be readily
and securely connected together, so that same are not liable to become accidentally
detached, while permitting same to be readily detached at will when required, and

page_text: one of such applications consists in the use of the invention for connecting watches
to guards or chains (in place of the usual "swivel"), or for connecting bracelets,
necklets, and articles of jewellery generally.

We, EDWARD FITZMAURICE INGLEFIELD, Lieutenant Royal Navy, late of
H.M.S Victoria," and ARTHUR DAVIS, a member of the firm of John Davis
& Son, Manufacturers of Mining Instruments and Electrical Engineers, of
118 Newgate Street, in the County of London, and All Saints Works, Derby,
in the County of Derby, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The present invention relates to improvements on the invention described in the
Specification of the prior Patent No. 14633 dated 16th Septr. 1890 granted to
the above named Edward Fitzmaurice Inglefield.
The invention described in the Specification of the above mentioned Patent
consists broadly in two clips or attachments, one of which is connected to or forms
part of one of each of the parts which it is desired to connect together, in such a
way that while same are not liable to become accidentally disconnected, they may be
readily disengaged, by bringing the two clips into a certain position in relation to
each other, when desired.
For this purpose each clip has a portion which is cut away and formed with
pointed ends, the two clips being connected and disconnected by bringing the cut-
away portions opposite each other and in a position at right angles to each other,
so that one clip or link will slip over the other.
According to the present invention instead of actually separating the metal or
other material at the cut-away portion, we propose leaving the pointed ends of one
of such clips connected together, and forming the space between the ends of the
cut-away portion of the other clip sufficiently large to pass over the portion
connecting the pointed ends of the first clip.
A further modification consists in varying the form of the parts of the clips
which permit the latter to be engaged and disengaged at will, and for this purpose
instead of forming such parts with "pointed" ends we make same of a curved,
convex, or irregular form on one clip, and of an opposite curve or form on the
other clip, so that one part will form a counterpart of the other, and, when the
clips are brought into the required relative positions with regard to each other, will
permit of one clip slipping over the other, so as to engage or disengage same when
required. It will be readily understood that, in this arrangement also, the ends of
the parts by means of which the two clips are engaged and disengaged, may in both
clips be separated by a small space (as in the arrangement described in the Specifi-
cation of Patent No. 14633, A.D. 1890, above referred to), or the ends of one clip
only may be so separated, while the ends of the other clip may be connected together.
The cut-away portions of the two clips may be so arranged as to enable the two
clips to be engaged and disengaged at any angle in relation to, each other, which
may be found most advisable or convenient in practice, according to the particular
or special requirements of any given application.
The invention (either in the form described in the Specification of the prior
Patent referred to, or constructed according to the different modifications thereof
described in the present Specification) is specially applicable for use in "bending
11

page_text: flags together for the purpose of signalling on board ships, and also generally for
joining chains, ropes, harness straps, or other parts which are required to be readily
and securely connected together, so that same are not liable to become accidentally
detached, while permitting same to be readily detached at will when required, and
one of such applications consists in the use of the invention for connecting watches
to guards or chains (in the place of the usual "swivel") or for connecting bracelets,
necklets, and articles of jewellery generally.
In order that the present improvements may be readily understood, we will now
proceed to describe same by the aid of the accompanying drawings, in which
Fig. 1 is a side elevation, and
Fig. 2 a front elevation of one of the parts of the clip, and
Figs. 3 and 4 corresponding views of the other part of the clip, constructed
according to one of the modifications of the present invention.
Fig. 5 is a perspective view of the two parts of the clip connected together, and
Fig. 6 another perspective view of same showing such parts in the position for
engagement or disengagement.
It will be seen that the part or link A has a cut-away portion a, but that the
portion cut away does not separate the material.
B is the other part or link of the clip, which has a cut-away portion b, such cut-
away portion extending right through the material, so as to form two pointed ends
separated by a space slightly in excess of the width of the unremoved portion of
the cut-away part a of the link A.
The method of connecting and disconnecting the links A and B will be readily
understood by reference to Figs. 5 and 6 of the drawings.
Fig. 7 is a front elevation of the part or link A, and
Fig. 8 a corresponding view of the other part or link B of a modified form of
the clip, and
Fig. 9 is a perspective view showing the method of connecting and disconnecting
same.
It will be seen that as in the arrangement above described the removed portion a
of the link A does not pass right through the material, but the form of such
removed portion (as well as that of the corresponding part 6 of the link B) is in
this case of circular form, instead of being angular as in the preceding arrangement.
Fig. 10 is a front elevation of the part or link A, and
Fig. 11 a corresponding view of the part or link B, and
Fig. 12 a perspective view showing the method of connecting and disconnecting
such links A and B, the whole illustrating a further modification in which the cut-
away portions of the links are of irregular form, the cut-away portion of the
link A still, as in the case of the preceding arrangements, not extending right
through the material.
Figs. 13 and 14 are front elevations of the parts or links A and B respectively, and
Fig. 15 a perspective view showing the method of connecting and disconnecting
such links, the whole illustrating a further modification in the form of the cut-away
portions, which in this case in both the link A and link B pass right through
the material.
Figs. 16, 17, and 18 are similar views showing a still further modification in the
form of the cut-away portions of the links, in which such cut-away portions
extend right through the material in both of the links.
It will be readily understood that the form of the cut-away portions of the
links A and B, no matter whether same extends right through the material or not,
may be varied indefinitely, so long as the portion removed from one link forms
approximately the counterpart of the portion removed from the other link.
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:—
1. The improved clip or attachment consisting of two parts or links from one

page_text: of which a portion is removed which does not extend right through the material of
which such link is formed, while the other link has a portion of its material removed
which does extend right through such¨material, and which removed portion forms
approximately the counterpart of the removed portion of the first link, substantially
-as specified.
2. The improved clip or attachment consisting of two parts or links from one of
which a portion is removed, and from the other of which a portion is removed
forming approximately the counterpart of the removed portion of the first link,
the form or configuration of such removed portions being capable of variation,
substantially as specified.
