Improvements in the Manufacture of Curry Combs.
I, WILLIAM HENRY TILDESLEY, of 88, Walsall Street, Willenhall, in the County
of Stafford, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention consists of the herein described improvements in the manu-
facture of curry combs whereby the cost of production is reduced.
According to one part of this invention I make as follows those parts of the
curry comb which are known as the knocker bars and which project at the sides
of the curry comb. Heretofore it has been customary to make the said knocker
bars out of a taper section flat iron or steel bar, parts of which have been cut
away from each end leaving projections to form the knockers which are forged
into a flattened shape with projecting nipples or tongues to close down on to
the edges of the curry comb plate to form stops and assist in securing the knocker
bar thereto. This method of manufacturing the knocker bars is comparatively
expensive as they have to be heated and forged by skilled labour.
By the first part of this invention I am enabled to dispense with skilled
labour and the heating of the blanks in making the said knocker bars.
or
tongues.
are
The dies
This part of my invention is carried out as follows:-I take a knocker bar
blank of the usual shape and by means of a pair of dies in a stamp or press I
compress and flatten the said end portions of the knocker bar plank and on that
side which comes against the curry comb plate I form two short projecting
pieces which correspond in shape and size and position with the required two
nipples
sunk to give the proper shapes.
In the next operation a V-shaped cut is made between each of the
tongues and the flat part of the knocker bar thereby dividing the tongues
and turning them upwardly in inclined directions so that when the knocker bar
is placed on the curry comb plate the tongues can be closed down to grip the
same. The operations above described can be performed without heating the
knocker bar blank.
According to the second part of this invention I secure the knocker bars and
the toothed comb bars to the curry comb plate without the use of rivets as
follows: I employ a pointed punch and a bed or bottom tool which latter has a
hole rather larger than the punch. The pointed punch is driven through the
curry comb plate and the flattened part of the knocker bar or toothed comb
bar thereby forcing the metal out around the hole both in the bar and in the
curry comb plate like two eyelets one within the other. The curry comb plate
and the bar are now turned over, and a pointed punch made with a closing
shoulder or collar spreads over the evelet part of the bar and curry comb plate
and closes them down around the hole thereby effectually securing the bar and
the curry comb plate together. The bed or bottom tool which I use for the

page_text: closing over of the said eyelet part has an annular rib round the hole in the
curry comb plate and adds to the appearance of the same.

improvements in the Manufacture of Curry Combs.
I, WILLIAM HENRY TILDESLEY, of 88, Walsall Street, Willenhall, in the County
of Stafford, 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 consists of the herein described improvements in the manu-
facture of curry combs whereby the cost of production is reduced.
According to one part of this invention I make as follows those parts of the
curry comb which are known as the knocker bars and which project at the
sides of the curry comb. Heretofore it has been customary to make the said
knocker bars out of a taper section flat iron or steel bar, parts of which have
been cut away from each end leaving projections to form the knockers which are
forged into a flattened shape with projecting nipples or tongues to close down
on to the edges of the curry comb plate to form stops and assist in securing the
knocker bars thereto. This method of manufacturing the knocker bars
paratively expensive as they have to be heated and forged by skilled labour.
By the first part of this invention I am enabled to dispense with skilled
labour in making the said knocker bars.
com-
This part of my invention is carried out as I will describe by referring to
Figs. 1 to 7 of the accompanying drawings of which Fig. 1 is an elevation and
inverted plan of a knocker bar constructed in accordance with this invention;
Fig. 2 is an elevation and Fig. 3 is a plan of the said knocker bar secured on to
the curry comb a part of which is shewn in cross section in Fig. 2 and broken
off in Fig. 3; Fig. 4 is the blank from which the said knocker bar is formed;
and Fig. 5 shews the said knocker bar blank after it has been stamped to form
the nipples or tongues in accordance with this invention but before the nipples
or tongues have been divided as in Fig. 1; Fig. 6 is a sectional elevation and
inverted plan of the top die and Fig. 7 is a sectional elevation and plan of the
bottom die which I use for stamping the blank represented in Fig. 1 into the
shape represented by Fig. 5. The remaining figures of the drawings illustrate
the second part of my invention hereinafter described.
In carrying out the first part of my invention I take a knocker bar blank A
of the usual shape represented in Fig. 4, that is to say, this blank is a piece of
taper section bar with portions cut away at each end from the thinner edge
leaving the parts a¹ a² of the shape shewn in Fig. 4. I stamp the end por-
tions a¹ a² of the knocker bar blank A in the dies BC (parts of which are shewn
in Figs. 6 and 7) which dies are so sunk at b c as to flatten the end portions al a
and form on the thicker side a³ the two short projections at a³ which correspond
in shape and size and position with the required two nipples or tongues at a
shewn in Figs. 1, 2 and 3. The bottom die B is sunk to correspond with one of
the parts aa of the knocker bar above the level of the line a³ in Fig. 5 and
the depression in the top die C is made to correspond in shape and size with
one of the nipples or tongues a a³ and the end portions a¹ a² or knockers which

page_text: are below the line a³ in Fig. 5 so that when the knocker bar is stamped in these
dies as aforesaid the end portions will have the shape represented by Fig. 5.
In the next operation a V-shaped cut e is made between each of the tongues at a³
and the knocker bar ends. This can be done by making a cut with a thin saw
under each tongue and then opening out the cut so as to bend the tongues as
shewn in Figure 1 so that when the knocker bar A is placed in position on the
curry comb plate D the tongues a' as can be closed down to grip the same as in
Figs. 1 and 2. The knocker bar A is further secured by two rivets f which pass
through the swelled parts a6 of the knocker bar and through the plate D.
According to the second part of this invention I secure the knocker bars and
the toothed comb bars or plain bars to the curry comb plate without the use of
rivets as I will now describe by referrings to Figs. 8 to 14 of the accompanying
drawings on which Fig. 8 represents in longitudinal section a part of a toothed
comb bar and a curry comb plate secured together in accordance with this inven-
tion; Fig. 9 is a longitudinal section shewing the same parts after they have
passed through one stage in the operations for securing them together in accord-
ance with this invention; Fig. 10 is a cross section of the toothed comb bar and
curry comb plate in the same stage as represented in Fig. 9; Fig. 11 is an eleva-
tion of the lower part of the punch and Fig. 12 is a front sectional elevation and
a cross sectional elevation and a plan of the bed or bottom tool which I use in
securing the toothed comb bar and knocker bar to the curry comb plate in
accordance with this invention and Fig. 13 is an elevation of the lower part of
the punch and Fig. 14 is a sectional elevation and plan of the bed or bottom tool
which I use in completing the fixing of the knocker and toothed comb bars to
the curry comb plate in accordance with this invention.
The
In carrying out the said second part of this invention I employ a pointed
circular punch G and a bed or bottom tool H (Figs. 11 and 12) which latter
has a circular hole h rather larger than the punch G. In fixing the toothed
comb bar I to the curry comb plate D the toothed comb bar is placed in position
on the curry comb plate and on the bed or bottom tool H which is made narrow
enough to pass up between the sides of the trough section comb bar I.
pointed punch G is driven through both the curry comb plate D and the toothed
comb bar I thereby forcing the metal out round the hole in the comb bar I
and in the plate I like two eyelets di one within the other (see Figs. 9 and 10).
The curry comb plate D and toothed comb bar I are now turned over so that
the plate D is at the bottom and the punch J Fig. 13 made with a closing
shoulder or collar j is forced down the hole d spreading over the eyelet parts d
and of the plate D and comb bar I respectively closing them down round the
hole d as in Fig. 8 thereby securing the bar I and the curry comb plate together.
The bed or bottom tool K which I use for the closing over of the eyelet part has
an annular recess round the hole k which forms an annular rib round the
hole in the curry comb plate 1) thereby adding to the appearance of the same.
I fix the plain comb bars and knocker bars to the curry comb plate as above
described and illustrated by Figs. 8 to 14 in reference to the toothed comb plate.
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:-
:-
1. The manufacture of curry comb knocker bars from taper section iron or
steel blanks such as represented in Fig. 4, by first stamping the end portions of
the said blank in dies which flatten the said end portions and form the two short
projections a a5 thereon as represented in Fig. 5 and then cutting and turning
the said projections away from the end portions of the knocker bar ready to be
attached to the curry comb plate, substantially as set forth.
2. The method of fixing comb bars to a curry comb plate by punching holes
through both so as to form eyelet like projections one within the other and
then spreading out these eyelet like projections so as to cause them to engage

page_text: together substantially as herein before described with reference to Figs. 8 to 14
of the accompanying drawings.
3. The method of fixing a knocker bar to a curry comb plate by punching holes
through both so as to form eyelet like projections one within the other and
then spreading out these eyelet like projections so as to cause them to engage
together substantially as herein before described with reference to Figs. 8 to 14
of the accompanying drawings.
