Improvements in the Manufacture of Water and Gas-pipe Hooks.
I WILLIAM HENRY DRANSFIELD of The Views Darton near Barnsley in the
West Riding of the County of York Chaplet and Hook Manufacturer, 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 the manufacture of the metal hooks which are
employed for driving into walls or other surfaces for securing water or gas pipes
thereto and the objects of the invention are to improve and economize such
manufacture.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the annexed sheet of drawings and the following explanation thereof.
According to one modification of my invention I propose to roll or forge a strip
of steel or other suitable metal of a width equal to the length of the required
hook before the "bill is turned up being tapered off towards each edge and with
a projecting web or rib running along the centre at one side as shown at Fig. 1 in
the annexed drawing and end view at Fig. 2. a being the double tapered plate or
strip and 6 the projecting web or rib.
From this plate or strip a so formed I then cut off a series of wedge-like pieces
as shown by the dotted lines on Fig. 1 each piece so cut off being of the form
shown at Fig. 3 the section of the rib or web b forming the neb for driving and
the wider end a' requiring only to be curved or bent round into the form shown at
Fig. 4 to make a complete pipe hook ready for use, without any further forging
or hammering.
According to another modification of my invention I take a bar or rod of steel
or other suitable metal of an oblong quadrilateral section as shown at Fig. 5 the
larger dimension being rather wider than the end of the finished "bill" and the
smaller dimension being equal to the depth of the thickest part of the hook
including the "neb."
I then cut this bar or rod in the manner shown at Fig. 6 each piece so cut off
being of such a form (as shown at Fig. 7) that when divided in a diagonal
direction as shown by the line c it will form two pieces corresponding to Fig. 3
and will only require the "bill" turning or bending over to make a complete
hook.
It will be seen however on reference to Fig. 6 that in this case the point of
each hook when seen sideways will of necessity be of the same depth as the "neb"
and the end of the "bill" will also be of the same thickness and if this should be
considered an objection the two ends can easily be further reduced by a slight
hammering.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
First. The method of manufacturing water or gas pipe hooks by first rolling or
forging a bar or strip of steel or other suitable tapering towards each edge and
having a rib or web projecting from one side along the centre, next cutting off
wedge-like transverse sections from the same and then bending up the wide end
into the form of a "bill" or hook substantially as above described and illustrated
by Figs. 1, 2, 3, and 4 of the drawings annexed.
Secondly. I claim the method of manufacturing water or gas-pipe hooks from

page_text: a quadrilateral bar of steel or other metal by cutting the same into blanks in the
manner hereinbefore described, with reference to Fig. 6 of the annexed drawings
and then dividing each section into two wedge-like pieces by a diagonal cut as
shown at Fig. 7 and lastly bending up the broad end into the form of a "bill" or
hook, and
Thirdly I claim the improved water and gas-pipe hooks manufactured sub-
stantially in the manner hereinbefore described.
Dated this 30th day of January 1892.
