I, SAMUEL TIMINGS, of 23 Great Hampton Street, Birmingham, Warwickshire,
Brassfounder, do hereby declare the nature of this invention to be as follows:-
This invention has reference to the manufacture of loops for coffin handles,
cramps" for bags,
cabinet handles, and for other drop handles, knobs or
portmanteaus, trunks, and for other like purposes, shanked buttons, and picture
nails, and other ornamental nails; and this invention consists in an improved
method of making the heads of the said articles from sheet metal blanks and of
attaching the said heads to their shanks, whether such shanks are divided as in the
case of knobs or cramps, handle loops and buttons, or single as in the case of
picture nails and other ornamental nails.
C
In carrying out my invention as applied for instance to the manufacture of the
said knobs or cramps," I take a solid circular blank of suitable ductile sheet
metal or alloy somewhat larger in diameter than the required knob. By means of
cup like
one or more pairs of dies worked in a stamp or press I raise a central
projection or boss on one side of the said blank. The sides of this cup are of,
double thickness and on the other side of the blank there is an annular recess
which is the space between the walls of the cup. The shank of the knob or
cramp
"is of the usual kind namely a piece of wire bent centrally together to
form the divided shank and its looped or bent end pressed outwardly and enlarged
from a smaller neck to enable the said shank to be fixed to the head as hereinafter
described.
The enlarged bent end of the divided shank is placed in the said cup of the
head and, by dies worked in a stamp or press, the cup is closed round the enlarged
end of the shank so as to secure the same to the head. These dies also impart the
required domed or other form to the head and close up the said annular recess so
that the head when viewed from the outside appears to be solid.
When making handle loops with divided shanks for their attachment I either
proceed as above described with reference to knobs or cramps and cut a slot
in one or in both sides of the loop for the ends of the handle to work in; or
I make the said handle loop of two sheet metal blanks laid face to face one of
them having a central hole through which the divided shank is threaded. The
enlarged bent end of the divided shank is thus between the two blanks and it is
there firmly held by the edge of one blank being closed over the edge of the other
blank and by the two blanks being then stamped together, the slot or slots to take
the end or ends of the handle being then cut in as above described.
I make the heads of a picture nail and other ornamental nails each from a solid
blank and attach the solid headed and pointed shank thereto in the same way as
hereinbefore described with reference to knobs or cramps, the blanks and finished
heads being either circular or of any other desired form.
I make buttons from sheet metal blanks similarly as hereinbefore described with
reference to knobs the divided or headed end of the button shank being secured in
the said cup of the partly made button by closing the cup around the same as
hereinbefore described with reference to knobs.

Improvements in the Manufacture of Handle Loops, Knobs, Cramps,
Buttons, Picture Nails, and other Ornamental Nails.
I, SAMUEL TIMINGS, of 23, Great Hampton Street, Birmingham, Warwickshire,
Brassfounder, 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 has reference to the manufacture of loops for coffin handles,
"for bags,
cabinet handles, and for other drop handles, knobs or cramps
portmanteaus, trunks, and for other like purposes, shanked buttons, and picture
nails, and other ornamental nails; and this invention consists in an improved
method of making the heads of the said articles from sheet metal blanks and of
attaching the said heads to their shanks whether such shanks are divided as in the
case of knobs or cramps, handle loops and buttons, or single as in the case of
picture nails and other ornamental nails.
I will describe my invention by referring to the accompanying drawings on
which Figures 1 to 9 illustrate the progressive stages in the manufacture of one of
the said cramps or knobs in accordance with this invention from the sheet metal
blank shewn by Figure 1 to the finished cramp or knob shewn in sectional
elevation and in plan by Fig. 9; Fig. 10 shews the divided shank of the same
separately; Fig. 11 shews the said cramp or knob on an enlarged scale but
furnished with a screwed shank; Figs. 12 and 13 shew how the said cramps or
knobs are made to serve as single and double handle loops respectively; Fig. 14
shews in sectional elevation a button made in accordance with this invention; and
Fig. 15 shews a drawer knob or other knob and a rose the said knob being made
and attached to its screwed shank in accordance with this invention.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
In carrying out my invention as applied for instance to the manufacture of the
said knobs or <6 cramps" as shewn by Figures 1 to 10 both inclusive I take a solid
circular blank (Figure 1) of suitable sheet metal or alloy somewhat larger in
diameter than the required knob. By means of suitable pairs of dies worked in a
stamp or press I raise a central cup like projection or boss a on one side of the
blank (as shewn in Figure 4). I prefer to use three pairs of dies to work the
blank into this shape shewn by Figure 4. The first pair of dies form the blank
into the cup shape shewn by Fig. 2; the second pair of dies reduce the diameter
and depth of the cup a and form a flange around the same as shewn in Figure 3 ;
the third pair of dies reduce the depth of the cup a by rolling down the Hange b
to about on a level with the bottom of the cup a so that the walls of the cup a are
now of double thickness and on the other side of the blank or flange b there is an
annular recess c (see Figure 4) which is the space between the walls of the cup a.
By means of a fourth pair of dies the cup a is then further reduced in size see
Figure 5 and the sides or walls of the cup are somewhat closed together and the
flange b made flatter and slightly bent up around the edge d; and then by means
of a fifth pair of dies the mouth of the cup a is somewhat reduced in diameter
(see Fig. 6) and the rim d is turned up. At this stage the annular recess c has
almost disappeared. The shank E (shewn separately by Fig. 11) of the knob or
cramp is of the usual kind namely a piece of wire bent centrally together to form
the divided shank and its looped or bent end pressed outwardly at e¹ e² and
enlarged from a smaller neck e to enable the said shank E to be fixed to the head
of the knob or cramp as hereinafter described.
The enlarged bent end e¹ e² of the divided shank E is placed in the cup a of the
flange or head 6 and, by dies worked in a stamp or press, the cup a is closed round
the enlarged end ee of the shank E so as to secure the same to the head b.
These dies also impart the required domed or other form to the head see Figures 9

page_text: and 11 and close up the annular recess c so that the head when viewed from the
outside appears to be solid. I prefer to employ a series of three dies for these
processes that is to say one pair of dies partly closes the cup a around the shank E
and folds down the edge d of the head (see Fig. 7) the next pair of dies still
further close the cup around the shank (see Fig. 8) and slightly dishes the head b
and the last pair of dies close the cup firmly around the shank and dome the
Instead of the divided shank E
head to the required shape as shewn in Fig. 9.
a headed solid shank E (either screwed or not) may as shewn in Fig. 11 be fixed
to the head b in the manner above described.
When making handle loops with divided shanks for their attachment I either
proceed as above described with reference to knobs or cramps and cut a slot fin
9 to
one (Fig. 12) or in both (Fig. 13) sides of the loop for the ends of the handle
work in; or as shewn by Figs. 16, 17 and 18 I make the handle loop of two sheet
metal blanks marked respectively h and i laid face to face one of them having a
central hole through which the divided shank E is threaded see Fig. 17. The
enlarged bent end e¹ e² of the divided shank E is thus between the two blanks h
and and it is there firmly held by the edge of the blank i being closed over the
edge of the other blank and by the two blanks being then stamped together, the
slot or slots to take the end or ends of the handle g being then cut in as above
described.
I make the head of a picture nail and other ornamental nails each from a solid
blank and attach the solid headed and pointed shank thereto in the same way as
hereinbefore described and shewn by Figs. 1 to 11 both inclusive with reference to
knobs or cramps, the blanks and finished heads being either circular or of any
other desired form.
I make buttons from sheet metal blanks similarly as hereinbefore described with
reference to knobs or cramps the divided or headed end of the button shank k
being secured in the cup a of the partly made button by closing the cup around the
same as hereinbefore described with reference to knobs or cramps. A button made
in this way is shewn in section by Figure 14.
Fig. 15 shews my invention applied to a drawer knob or other knob which has a
shank for its attachment. The screwed or other headed shank E' or a divided
shank E is fixed to this knob in the manner above described with reference to the
knobs or cramps for bags and the blank is raised into the required form of the
knob by suitable dies as will be understood.
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 :-
:-
1. In the manufacture of handle loops knobs cramps buttons picture nails and
other ornamental nails attaching the divided or the single shank portion to the
head portion in the manner hereinbefore described and illustrated by the
accompanying drawings, that is to say, forming a central cup like projection a of
double thickness on the head portion and then closing the cup on to and around
the head of the shank substantially as hereinbefore described and illustrated by
Figs. 1 to 15 both inclusive of the accompanying drawings.
2. Handle loops knobs cramps buttons picture nails and other ornamental nails
having the head portion made from sheet metal blanks and attached to the shank
portion in the manner substantially as hereinbefore described and illustrated by
Figs. 1 to 15 both inclusive of the accompanying drawings.
3. The improved handle loop herein before described with reference to Figs. 16, 17
and 18 of the accompanying drawings and whether made with a single or with a
double shank.
