We EDMUND TONKS and WILLIAM HENRY TONKS trading as William Tonks
and Sons of Moseley Street Birmingham in the County of Warwick Manufacturers
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION AND MANUFACTURE OF PICTURE HOOKS AND OTHER SIMILAR HOOKS
to be as follows:-
"
Our improvements are principally applicable to hooks for hanging pictures maps
and other articles which are suspended by cords or lines but are in part applicable
to books for other purposes such for example as cornice pole hooks.
Our invention consists principally in making that portion of the hook on which
the cord or line of the picture map or other article is supported in the manner
hereinafter described whereby a large curved bearing surface for the cord or line is
obtained and the adjustment of the cord or line is readily effected. By the use of
the large bearing surface described and the absence of a cutting edge the risk of
the rupture of the cord or line is much diminished.
Our invention further consists in manufacturing picture rod and other rod hooks
from sheet metal in the manner herein after described.
In constructing a picture hook according to our invention we make the lower
part of the hook of a trough form the trough being bent downwards into a nearly
semi-circular figure or other portion of a circle the cord or line being.supported on
the convex bottom of the trough. A hook thus constructed has at its bottom
a long curved bearing trough shape in cross section for the cord or line to rest
upon the said curved bearing extending about an inch on each side of the body of
the hook.
We make the curved bearing described together with the flat nail plate or the
eye by which the hook is connected to a wall or other surface from a blank of
sheet metal by pressing tools.
In making picture rod hooks or rod or beading hooks for supporting articles in
shops and shop windows and other places we make the long bearing for the cord
or line as well as the upper hook part from sheet metal the said upper hook part

page_text: in the case of rod hooks being made elastic so that it will spring upon the rod so
as to fix the hook securely to the rod. Or the bottom curved bearing for the cord
or line may be used in combination with a hook having a ring at its upper part
the said ring being engaged with the picture or other rod by an end sliding motion.
The ring part of this hook is made by bending a portion of a trough shaped sheet
metal strip into a nearly circular form the other portion of the strip being bent
into a hook form or into the curved bearing herein before described. That part of
the ring which joins the stem or body of the hook is secured to the said body by
the closing of the lower hook part upon a nearly flat extension of the bent end of
the ring.
.
Although we prefer to make from sheet metal the picture hooks and other like
hooks having the long curved bearing for the supporting cord or line yet the said
hooks may be made by casting and dressing in the ordinary way.

We EDMUND TONKS and WILLIAM HENRY TONKS trading as William Tonks
and Sons of Moseley Street Birmingham in the County of Warwick Manufacturers
lo hereby declare the nature of our Invention for "IMPROVEMENTS IN THE

"
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
Our improvements are principally applicable to hooks for hanging pictures maps
and other articles which are suspended by cords or lines but are in part applicable
to hooks for other purposes such for example as cornice pole hooks.
Our invention consists principally in making that portion of the hook on which
the cord or line of the picture map or other article is supported in the manner
hereinafter described whereby a large curved bearing surface for the cord or line
is obtained and the adjustment of the cord or line is readily effected. By the use
of the large bearing surface described and the absence of a cutting edge the risk of
the rupture of the cord or line is much diminished.
Our invention further consists in manufacturing picture rod and other rod hooks
from sheet metal in the manner hereinafter described.
In constructing a picture hook according to our invention we make the lower
part of the hook of a trough form the trough being bent downwards into a nearly
semi-circular figure or other portion of a circle the cord or line being supported on
the concavo convex bottom of the trough. A hook thus constructed has at its
bottom a long curved bearing trough shape in cross section for the cord or line to
rest upon the said curved bearing extending about an inch on each side of the
Dody of the hook.
In making picture rod hooks or rod or beading hooks for supporting articles in
shops and shop windows and other places we make the long bearing for the cord or
line as well as the upper hook part from sheet metal the said upper hook part
in the case of rod hooks being made elastic so that it will spring upon the rod
so as to fix the hook securely to the rod. Or the bottom curved bearing for the
cord or line may be used in combination with a hook having a ring at its upper
part the said ring being engaged with the picture or other rod by an end sliding
motion. The ring part of this hook is made by bending a portion of a trough
shaped sheet metal strip into a nearly circular form the other portion of the strip
being bent into a hook form or into the curved bearing hereinbefore described.
That part of the ring which joins the stem or body of the hook is secured to the
said body by the closing of the lower hook part upon a nearly flat extension of
the bent end of the ring.
We will now proceed to describe with reference to the accompanying Drawings
the manner in which our invention is to be performed.
Figure 1 represents in front elevation Figure 2 in side elevation and Figures 3
and 4 in section taken at right angles to one another a picture hook constructed

page_text: .
according to our invention a is the large curved bearing of the hook on which
the cord or line c is supported and b is the eye plate by which the hook is
connected to the wall or other surface. The said large curved bearing a of the
hook is of a trough shape in cross section and on the concavo-convex bottom of
the said trough the cord or line is supported as represented in the drawing. By
constructing the line or cord supporting part a of the picture hook in the manner
described and represented that is making it of a curved open trough form the cord
or line can be placed in and removed from the said part a with great facility and
in consequence of the absence of a cutting edge in the supporting part the risk of
the rupture of the cord or line is much diminished.
Figure 5 represents in front elevation and side elevation a picture hook in which
a flat nail plate d is used instead of the eye plate represented in Figures 1, 2, 3
and 4.
We make the long curved bearing a together with the flat nail plate d or the
eye plate b by which the hook is connected to a wall or other surface from a blank
of sheet metal by pressing tools the long curved bearing a being made from the
lower part of the blank and the eye plate b or flat nail plate & from the upper part
of the blank.
Figure 6 represents in front elevation and Figures 7 and 8 in section taken at
right angles to one another a sheet metal picture rod hook or other rod or beading
hook constructed according to our invention. The lower part of this hook is
furnished with the curved trough shaped bearing a for the cord or line to rest
upon and the upper part with the hook e for engaging with the rod f (or beading)
or the hook e may be replaced by a ring the said ring being engaged with the
picture or other rod f by an end sliding motion..
In making the picture rod hook or other 'like hook Figures 6, 7 and 8 we cut out
from sheet metal the T shape blank represented in Figure 9. From the body
part e² of the blank we, make the hook e and from the cross head a³ we make the
long curved bearing a. We first give the body e² of the blank a trough form and
bend it into the partly made hook represented in Figures 10 and 11 and afterwards
fashion the cross head u² of the blank into the long curved bearing a as represented
in back elevation in Figure 12 front elevation in Figure 13 and side elevation in
Figure 14. The shape of the hook e is afterwards perfected in the manner
represented in Figure 15.
Although we prefer to make from sheet metal the picture hooks Figures 1. 2. 3.
4 and 5 and the picture rod and other like hooks 'Figures 6, 7 and 8 having the
long curved bearing a for supporting the line or cord yet the said hooks may be
made by casting and dressing in the ordinary way.
In making from sheet metal a picture rod or other like hook having a ring at
its upper part for engaging with the picture or other rod by an end sliding motion
we proceed as follows:-
.
We cut out from sheet metal a blank of the kind represented in Figure 16 and
afterwards give a trough form to the said blank as represented in Figure 17. The
ring part of the hook is made by bending. the portion g of the trough shaped strip
at its middle and bringing the two parts g², g³ at right angles to one another as
represented in Figure 18. By a second bending or shaping operation a semi-circular
figure is given to the part g³ so as to complete the ring i and the narrow end h is
brought opposite and made to lie in the trough of the part g2 as represented in side
elevation in Figure 19 and edge view in Figure 20 The edges of the trough
part g2 are next closed upon the narrow part of the partly made hook as repre-
sented in side elevation in Figure 21 edge view in Figure 22 and end elevation
partly in section in Figure 23. From the connected parts g², h or the nearly flat
extension of the ring i the hook is made in the manner represented in side eleva-
tion in Figure 24 and front elevation in Figure 25 where the hook is marked k.
When in place of the narrow hook k the long curved bearing herein before 5
described is to be combined with the ring like top i of the hook the end of the

page_text: narrow part h of the blank Figure 16 is furnished with a cross piece of the kind
represented in Figure 9 and marked a from which cross piece a² the said long
curved bearing is made.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that we
claim as our invention of "Improvements in the construction and inanufacture of
