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 to be as follows:-
This invention relates to improvements upon the subject matter of Letters
Patent granted to me dated 2nd February 1892 No. 1961, the object of the present
invention being to make a pipe hook of a stronger kind than those made under my
said Patent, and more suitable for rough work and wide seams than those made
according to my previous invention.
According to my present invention I roll or forge a strip of steel or other
suitable metal of a width equal to the extreme length of the required hook before
the "bill" is turned up, and having a projecting web or rib running along about the
centre. On one side of the rib the metal for forming the "bill" is rolled or forged
parallel (or nearly so) and thinner than that on the other side, which is stronger
where it joins the rib or "neb" and tapers gradually off towards the edge which
forms the point of the hook.
Instead of cutting the blanks off this strip in alternate wedge-like forms (as
before) I cut them all off entirely or partially parallel and of such a width as is
required for the hook, so that all the points are on one side and all the bills on the
other, and the "bill" may then be turned up in the usual manner; the hook would
in the first case be all of the same breadth from "bill " to point, the latter being of
a chisel shape, but if the point is required to be tapered in both directions, then I
cut off a wedge like piece from each side of the point such piece being wasted.
By this invention I am enabled to make a far stronger hook than formerly, which
will bear much rougher usage in driving, as the "neb" is much more solid and
better supported by the increased thickness or depth of the shank behind the same
and the shank can be made longer than the "bill" or shorter if desired by rolling
one side of the strip wider or narrower than the other accordingly, which could not
be done according to my previous invention.
"
I may here remark that it is not absolutely necessary to roll an actual rib on the
strip of metal as the "neb can be produced by rolling the "bill" side thin and
parallel then making a step the depth of the "neb" and thence tapering right
away to the point.

[Price 8d 1

page_text: performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements upon the subject matter of Letters
Patent granted to me dated February 2nd 1892 No. 1961, the object of the present
invention being to make a pipe hook of a stronger kind than those made under my
said Patent, and more suitable for rough work and wide seams than those made
according to my previous invention.
The nature of my said present 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 sheet of drawings hereunto annexed and the following explanation
thereof.
According to my present invention I roll or forge a strip of steel or other
suitable metal of a width equal to the extreme length of the required hook before
the "bill" is turned up as seen in plan view at Fig. 1 on the annexed drawings,
and transverse section Fig. 2, and having a projecting rib running along on one
side about the centre thereof. On one side of the rib the metal b for forming
the "bill" is rolled or forged parallel (or nearly so) and thinner than that part c
on the other side which is stronger where it joins the rib or "neb a and tapers..
gradually off towards the lower edge which forms the point of the hook as seen.
at Fig. 2.
"
Instead of cutting the blanks off this strip in alternate wedge-like forms (as
before) I cut them all off (in some cases parallel as shown by the dotted lines in
Fig. 1) and of such a width as is required for the hook, so that all the points are
formed on one side of the strip and all the "bills" on the other side thereof, and
the "bills" may then be turned up in the usual manner (see Fig. 4) and the hook
would in this case be all of the same breadth from "bill". to point (see Fig. 3) the
latter being of a chisel shape, but if the point is required to be tapered in both
directions then I cut off a wedge like piece from each side of the point, as shown
at Fig. 5, such pieces being wasted.
In some cases when I wish to obtain a more or less tapered point without waste,
I propose, instead of forging or rolling the bar or strip straight as shown at Fig. 1
to forge or roll the same in a curved or circular form as shown at Fig. 6 the outer
edge b being the edge from which the "bill" is formed and the inner edge c for the
shanks, and then by cutting across the bar in a wedge-shaped or radial direction as
shown by the dotted lines on Fig. 6 the blanks would be formed with points
tapering at both sides and without any waste. This may be conveniently done by
first rolling the strip straight but with the side for forming the "bill" thicker than
is required as shown at Fig. 7 and then by forging this part out thinner it will
be lengthened so as to cause it to assume the curved form shown at Fig. 6.
I may here remark that in either case it is not absolutely necessary to roll an
actual rib on the strip of metal as shown at a, as the "neb can be produced by
rolling the "bill" side thin and parallel, then making a step to the depth of the
required "neb" and thence tapering right away to the point as shown at Fig. 8.
By the use of this invention I am enabled to make a far stronger class of hook
than formerly, which will bear much rougher usage in driving, as the "neb" is
much more solid and better supported by the increased thickness or depth of the
shank behind the same, and the shank can be made longer than the "bill," or
shorter if desired, by rolling one side of the strip wider or narrower than the
other accordingly, which could not be done according to my previous invention.
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 :--
"
The method of manufacturing water or gas pipe hooks by first rolling a bar or
strip of steel or other suitable metal of such a section that all the "bills
can be
formed from one side of a central rib or step, and all the points from the other,

partly so) substantially as hereinbefore described and illustrated by the drawings
annexed.
