Improved Means for Attaching Rods, Bars, Boards, or Battens to
Projecting Flanges, Bars, and similar Projections.
We, HENRY TREVISA CLARKE of Deptford Yard Sunderland in the County
of Durham Shipbuilder and ROBSON BROWN of Deptford Yard Sunderland in the
County of Durham Engineer do hereby declare the nature of this invention to he
as follows:-
Our invention relates to improvements in the methods of attachment to
projecting flanges bars & similar projections and is specially applicable in effecting
the attachment of a rod bar board or batten (hereinafter referred to as a batten)
to a series of flanges or projecting edges of a like nature such as angle bars flat
bars plate edges ships frames or beams and bulkhead stiffeners and though for
greater clearness in description we have detailed the possible cases for application
of our invention as above, it may be applied for attachment to any projection or
series of projections of a like nature.
Our invention may be applied for attachment to plain flanges and flanges
furnished with a swelling or bulb or other projection of a like nature on the outer
edge (hereinafter described as bulb flanges).
For convenience we describe our invention in its several forms under heads 1. 2. 3
(A and B) but all forms involve one or both of two methods.
Form I. can be applied to both kinds of flange.
Form 2. only to the bulb flange.
Forn 3. (A and B) to the bulb flange, and also to the plain flange with a suitable
modification of the claw as hereafter described.
Form 1. The hook bracket, consisting of an angle bracket having a hole for
connection in the projecting face of the bracket, and secured to the flange by
means of a bent stud passing through a hole in the same. This form can be
applied to both kinds of flange, and can be used for connection to the rod, bar,
board or batten by means of a nut and bolt, wood screw, pin & cotter or other
suitable means.
Form 11. The claw bracket, applied only to the bulb flange, having a hole in
the projecting face similar to that in Form I. and secured to the flange by means
of a bent claw passing round the bulb, & drawn up tight thereto by means of the
connection between the rod bar board or batten and the claw bracket itself.
Form I. The hook and claw cleat in two forms A and B. This form is
specially adaptable in the case where the rod or batten attached is required to be
frequently removed and replaced such as a ships cargo batten or other similar
fitting. It consists of a cleat or bracket rest of the usual form attached to the
flauge by means of a combination of the two methods of hook and claw already
described under Forms I and II.
A. The hook is the same as in the hook bracket Form I. but the stud is not
bent round and the claw is the same as in the claw bracket Form 11. The pro-
jecting face of the angle bracket is not required the hook and claw being connected
together in one piece.
B. Similar in all respects to A. except that the hook or stud is situated a little
above instead of level with the claw as in A. and has the end of the stud bent
upwards. The claw is the same as in the claw bracket Form II.

page_text: Both Forms 111 (A and B) are applicable to the bulb flange, but they may
be applied to the plain flange by making the claw flat instead of curved so that it
will lie against the Hat face of the plain flange.
Both Forms III (A and B) require a hole in the flange for attachment by means
of the hook or stud.
Our invention may be manufactured from steel iron or brass or any other
suitable material and may be wrought stamped or cast.

Improved Means for Attaching Rods, Bars, Boards, or Battens to
Projecting Flanges, Bars, and similar Projections.
We HENRY TREVISA CLARKE of Deptford Yard Sunderland, in the County
of Durham, Shipbuilder and ROBSON BROWN, of Deptford Yard, Sunderland, in
the County of Durham, Engineer 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 :-
Our invention relates to improved means for attaching rods, bars, boards or
battens and the like (hereinafter referred to as battens) to projecting flanges, bars
and similar projections (hereinafter referred to as flanges).
In the accompanying drawings we have shewn how our said invention may be
conveniently and advantageously carried into practice.
In Figs. 1-7 in the said drawings we shew 7 forms of our invention and, as
will be readily seen, each form involves one or both of two methods of attachment,
viz. :—
1. The hook A inserted in a hole or slot in the flange.
2. The claw B resting against the side of the flange, or embracing or engaging
against a bulb or swelling or transverse projection on the outer edge of the
flange.
Our invention in some of its several forms as shewn may be applied for
attachment to:-
1. Plain flanges.
And in other of its several forms to :-
2. Flanges furnished with a bulb, swelling, square or similar round or flat
transverse extension on their outer edges.
In some of its several forms our invention is also suitable for the attachment of
battens to flanges :-
1. By means of bolts and nuts, pins and cotters, screws or other similar methods.
And in others of its several forms it is suitable for the attachment of battens to
flanges:
2. By means of cleats or other similar methods.
In each of Figs. 1-7 on the accompanying drawings we shew a view of the
fitting alone on a larger scale, and also a separate view of the same fitting on a
smaller scale as applied to a flange for attachment with the batten in place.
For convenience and clearness we have shewn in the said smaller scale views
the flanges as forming part of ordinary angle bars, channel bars, zed bars and bulb
angle bars attached to plates, we do not however, confine ourselves to flanges in t'is
restricted sense, as it is obvious that our invention may be applied for attachment
to any description of flanges bars or similar projections.
We further particularly describe and ascertain the nature of our said invention
in its several forms by reference to the 7 views on the accompanying drawings.

page_text: Fig. 1, shews a cleat suitable for attaching a batten to a plain flange. It
consists substantially of a fitting arranged as a cleat provided with a hook A which
passes through a hole in the flange. The lower limb of the hook extends
downwards and terminates in a claw B which embraces the front edge and side of
the flange, and this together with the hook A keeps the cleat rigid when the batten
is in place.
Fig. 2, shews a cleat suitable for attaching a batten to a flange furnished with a
bulb or swelling on its outer edge. It consists substantially of a fitting arranged
as a cleat provided with a hook A and claw B as described under Fig. 1, differing
only in respect of the claw B which is not flat but is curved and embraces the bulb
or swelling on the outer edge of the flange. It will be obvious that this fitting in
order that the cleat may be always upright may either have the claw B on the right
hand and the hook A on the left as shewn on the larger scale view or vice versa
according as the bulb or swelling is on the right or left side of the flange. This is
shewn both ways on the smaller scale view under Fig. 2. In cases where the bulb
or swelling is on both sides of the flange either the right or left hand fitting may
be employed.
Fig. 3, shews a fitting arranged as a bolt bracket and is suitable for attaching a
batten to a flange provided with a bulb or swelling on its outer edge by means of
bolt and nut or other suitable fastening. It consists substantially of a claw B
curved to embrace the bulb or swelling on the outer edge of the flange, the claw B
extending round to the opposite side of the flange and forming a foot which presses
against the flange and together with the claw B causes the whole fitting to become
rigidly attached to the flange when the bolt passing through the batten and the
hole in the bracket at the back of the claw B is drawn tight by means of the nut.
To secure additional rigidity we sometimes add to this fitting a projection as shewn
which forces itself into the batten in the act of screwing up the bolt and thus
prevents any movement between the two, but this latter feature is not an essential
part of this fitting.
Fig. 4, shows a fitting arranged as a bolt bracket, and is suitable for attaching a
batten to any kind of flange by means of bolt and nut or other suitable fastening.
It consists substantially of a rectangular bracket having a hole in its transverse
limb, the limb lying parallel to the flange being provided with a book A inserted
in a hole in the flange. When the bolt passing through the batten and the hole in
the transverse limb of the bracket is drawn up tight so as to bring the batten tight
up against the outer edge of the flange the attachment is rigidly effected. The
smaller scale view under Fig. 4, shews on the right hand a flange furnished with a
bulb or swelling and on the left a plain flange.
Fig. 5, shews a cleat suitable for attaching a batten to a flange furnished with a
transverse extension on its outer edge. This extension may be to the right or left
of the flange. The fitting shewn in the larger scale view under Fig. 5, is for
attachment to a left hand extension, but as applied for attachment in the smaller
scale view it is shewn for a right hand extension. It consists substantially of a
fitting arranged as a cleat and having a flat palm resting against the face of the
transverse extension on the outer edge of the flange. This palm is provided with
a hook A which passes through a hole in this extension and by extending upwards
and to one side engages with the edge of the transverse extension and rests against
it, the upper end of the hook A being slightly curved for this purpose. The palm
of the fitting has also a claw B on one side which rests against the side of the
flange, the hook A and the claw B together when the batten is in place ensuring
absolute rigidity. We prefer to fit the claw B but it may be dispensed with if
other suitable means for maintaining rigidity are adopted, such as making the
hook A of square section and the hole through which it passes correspondingly
square, or by attaching the cleat itself to the hatten.
Fig. 6, shews a cleat similar to that described under Fig. 5. It is suitable for
attaching a batten to a Hange furnished with a transverse extension on its outer
edge. It consists of a fitting arranged as a cleat having a flat palm resting against

page_text: a face of the transverse extension and provided with a hook A passing through a
hole in this extension. This hook tends vertically upwards and terminates with
a flat foot resting against the inner face of the extension. The flat palm of the
fitting we prefer usually to provide with a claw B at either side engaging against
the side of the flange and the edge of its transverse extension to ensure absolute
rigidity. These claws B B however may be dispensed with by providing the same
alternative means described under Fig. 5, or by furnishing the flat foot at the
upper end of the hook A with a stud and inserting this in a corresponding hole in
the inner face of the transverse extension. This fitting as shewn is suitable
for flanges having the transverse extension either on the right or left hand side.
Fig. 7, shews a cleat similar in all respects to the cleat described under Fig. 2,
except that the hook A extends horizontally throughout, the end where it passes
into the hole in the flange being provided with a shoulder resting against the face
of the flange. This fitting may be either right or left hand as under Fig. 2, and
is suitable for attaching a batten to a Hange furnished with a bulb or swelling on
its outer edge.
Our invention in its various forms as above described may be manufactured from
steel, iron, brass or any other suitable metal or material and in the process of
manufacture may be wrought, stamped, cast or machined.
Our invention is specially applicable for the attachment of cargo batteus to
ships' frames, but it may be employed in any case where a rod, bar, board, batten
or the like is required to be attached to a flange or series of flanges, bars or similar
projections.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The hook A inserted in a hole or slot in a flange substantially as described,
as applied to a cleat or holt bracket for the attachment of a batten to a flange.
2. The claw B resting against the side of the flange or embracing or engaging
against a bulb or swelling or transverse projection on the outer edge of the flange
substantially as described, as applied to a cleat or bolt bracket for the attachment
of a batten to a flange.
3. The combination of the hook A and claw B as above described applied in the
same manner for the same purpose.
