I THOMAS GRIMSHAW of Witton near Blackburn in the County of Lancaster
Weaving Overlooker do hereby declare the nature of my Invention for
IMPROVEMENTS IN ROLLERS FOR SELF-ACTING TEMPLES USED IN LOOMS FOR
WEAVING" to be as follows:-
i
...
This Invention relates to the manufacture of the spiked rollers used in self-
acting temples.
These rollers are at present made from wrought iron and the spikes are formed
by striking or cutting up portions of the surface of the roller in the form of spikes
or pins, and when the points of these spikes or pins became dull the roller was
useless.
My improvement consists principally in making the rollers in a plain cylindrical
form either of wrought or cast iron, and in fixing thereon a shell (made as herein-
after described) so that when the points of the spikes or pins become dull the roller
can be renewed at a very small expense by fitting thereto another spiked shell..
These shells I form as follows: In a sheet of tin brass or other suitable metal
(preferably tin) I pierce a series of holes closely together so as to form a raised burr,
on the reverse side of the metal round each..hole like the surface of a nutmeg
grater, and these being bent round the plain rollers impart thereto a rough holding
surface which will, act upon the cloth instead of the spikes or pins above referred
to. I attach these roughened tin surfaces to the rollers by drilling holes through
the latter at suitable places in which I insert wooden plugs and I fix the tin thereto
by nails or screws.

Weaving Overlooker do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN ROLLERS FOR SELF-ACTING TEMPLES USED IN LOOMS FOR
WEAVING" 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 spiked rollers used in self-
acting temples.
These rollers are at present made from wrought iron, and the spikes are formed
by striking or cutting up portions of the surface of the roller in the form of spikes
or pins, and when the points of these spikes or pins became dull the roller was
uscless.
My improvement consists principally in making these rollers in a plain
cylindrical form either of wrought or cast iron, and in fixing thereon a “burred”
shell (made as hereinbefore described) so that when the points of the spikes or
"burrs" become dull, the roller can be renewed at a very small expense by fitting
thereto another spiked or "burred" shell.
These shells I form as follows. In a sheet, fillet, or-strip of thin steel, tin brass
or other suitable metal (preferably sheet steel) I pierce or perforate a series of holes
closely together so as to form a raised 'burr on the reverse side of the metal round
each hole (like the surface of a nutmeg grater) as shown highly magnified in plan
view Fig. 1 and in section Fig. 2 of the annexed Drawing, and these perforated,
burred sheets or strips being bent round the plain rollers and attached in any
convenient manner impart thereto a rough holding surface which will act upon the
cloth instead of the spikes or pins above referred to.
I attach these perforated burred surfaces to the rollers in any convenient.
manner; for instance, I sometimes drill holes through the roller at suitable places in
which I insert wooden plugs and I fix the perforated metal shell thereto by nails or
screws. Or, I bend a strip or fillet of the perforated or burred sheet steel, or other
metal spirally round a thin metal tube and solder it thereto at the ends (see Fig. 3)
or the shells may be made with a straight or other joint.
The inner tube I make with a "lap-joint" as shown at Fig. 4, and in the
roller b, b (see Fig. 5) I make a longitudinal groove c, c to receive this lap-joint, so
that when the shell (Fig. 3) is placed on the roller the joint a, a fitting in the
groove c, c in the roller, prevents the shell from being. turned round, or from
becoming loose on the roller.
It may also be fixed by soldering or by nails, screws or otherwise.
It will be evident that these perforated ".burred" metal shells may be applied to
the long temple rollers which extend across the loom, or to the short temple rollers
known as "side temples
and they may be used with advantage for renovating old
worn out rollers as well as for new ones.
.
"
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 improved manufacture of rollers for self-acting temples used
in looms for weaving, by fixing onto smooth or plain rollers of wrought or
cast metal, shells made of thin sheet steel or other suitable metal pierced or

perforated so as to leave "burrs on the surface, without limiting myself to any
particular method of bending the perforated metal or of fixing the same on to the
rollers.
