IMPROVEMENTS IN TEMPLES FOR LOOMS, AND IN APPARATUS OR MECHANISM CONNECTED THEREWITH
Year: 1881

page_text: LETTERS PATENT to John Hardaker, of Grace Street, Leeds, in the County
of York, Temple Manufacturer, for an Invention of "IMPROVEMENTS IN
TEMPLES FOR LOOMS, AND IN APPARATUS OR MECHANISM CONNECTED
THEREWITH."
PROVISIONAL SPECIFICATION left by the said John Hardaker at the
Office of the Commissioners of Patents on the 7th December 1881.
JOHN HARDAKER, of Grace Street, Leeds, in the County of York, Temple
Manufacturer. "IMPROVEMENTS IN TEMPLES FOR LOOMS, AND IN APPARATUS
OR MECHANISM CONNECTED THEREWITIL"
My Invention refers to an arrangement whereby more selvage or list of the
cloth and that only is gripped, preventing thereby temple damages to the cloth
at the same time the templing operation is more effectually performed.
For this purpose I provide grippers in pairs or sets. Each gripper consists of
a metal piece, and to it is hinged a pawl or small lever which has provided thereon
a pin for piercing and retaining the material, and a relieving piece or gauge.
These grippers are mounted on rods also in pairs or sets, such rods being
employed for transmitting alternate movements to the grippers; one set holds the
fabric stretched whilst the other is pushed forward to take hold of the material at
a fresh place. The rods on which the grippers are mounted are coupled in pairs
or sets to levers provided on the breast rail of the loom. The required recipro-
cating motion is imparted to the levers from cams or their equivalents, these being
actuated from some moving part of the loom. I also provide springs for pushing
forward the grippers when they are released for that purpose by the relieving
pieces or gauges. The grippers and other parts are supported in such a manner
that they yield for shuttle traps.
This Invention is applicable generally for retaining the fabric during the process
of manufacture at even and regulated widths.

JOHN HARDAKER, of Grace Street, Leeds, in the County of York, Temple

OR MECHANISM CONNECTED THEREWITH."
My Invention refers to an arrangement whereby more selvage or list of the
cloth and that only is gripped, preventing thereby temple damages to the cloth
at the same time the templing operation is more effectually performed.
For this purpose I provide grippers in pairs or sets. Each gripper consists of
a metal piece, and to it is hinged a pawl or small lever which has provided thereon
a pin for piercing and retaining the material and a relieving piece or guage. These
grippers aro mounted on rods also in pairs or sets, such rods being employed for
transmitting alternate movements to the grippers; one set holds the fabric
stretched whilst the other is pushed forward to take hold of the material at a
fresh place. The rods on which the grippers are mounted are coupled in pairs or
sets to levers provided on the breast rail of the loom. The required reciprocating
notion is imparted to the levers from cams or their equivalents, these being
actuated from some moving part of the loom. I also provide springs for pushing
forward the grippers when they are released for that purpose by the relieving
pieces or guages. The grippers and other parts are supported in such a mauner
that they yield for shuttle traps.
This Invention is applicable generally for retaining the fabric during the process
of manufacture at even and regulated widths.
And in order that my Invention may be more completely understood, reference
is given to the accompanying Drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation. Fig. 2, a plan looking at the top. Fig. 3, an end
elevation. Fig. 4, a section through A, B, Fig. 2. Figs. 5 and 6 are respectively
a front elevation and plan of grippers. Fig. 7 is a perspective view of a gripper.
In the Drawings I have only represented such parts of the loom as are necessary
to shew the application of my improvements. The grippers are mounted in pairs
or sets (consisting of any required number) on the plates a and b, and these are
attached to the rods c and d by means of bolts or screws e and f, and in order that
their position on the rods may be adjusted provide the slot holes g in the
plates a and b, also any required number of holes h in the rods c and d for the
insertion of the screws or bolts e and f. Each gripper consists of a metal piece j,
and to it is hinged at k a small pawl or lever 1, having provided thereon a pin m
for piercing and retaining the inaterial. A relieving or guage piece n is also
employed for lifting the lever or pawl land withdrawing the pin m from the
material by mounting the material during the lateral movement of the gripper.
Fig. 7 shews the gripper, pawl, or lever thus raised. The rods c and d are
employed for transmitting alternate movements to the grippers. One set holds the
fabric stretched whilst the other is pushed forward to take hold of the material in
the fresh place. Figs. 5 and 6 shew the grippers 1, 3, and 5, with the pawl or
lever mounted on the fabric having the pin m relieved therefrom by the guago
piece n; and also the grippers 2, 4, and 6 holding the fabric stretched.
The required lateral movement is imparted to the rods c and d carrying the

page_text: grippers from grooved cams p and p², mounted in adjustable bearings q on an
armr attached to a bracket & at t. The motion is conveyed to the rods c and d
through the adjustable straight levers u, short connecting rods v, bell cranks w,
connecting rods, toothed segment levers y. The segment levers are pivoted on
the sliding plate a¹, mounted on the studs 6', attached to the breast rail c'. Tho
sliding plate is retained in the position shewn in the Drawing by the spring d',
and should the shuttle come in contact with any of the parts at N or M, the
springs d' and f¹ allows the sliding plate a¹ and temples to recede therefrom,
forming thereby a shuttle trap provision. In order to impart a forward movement
to the grippers I employ the projecting inclines e' attached to the rods c and d at
any convenient point and the springs attached to the breast rail c¹.
It will be readily understood that as the rods c and d are moved in the direction
shewn by arrows g¹ the springs f' come in contact alternately with projecting
inclines e, thus giving alternately to the sets of grippers a movement in the
direction shewn by arrows i for the purpose of allowing the grippers to seize the
material in a fresh place. This movement is effected when the pawls are in the
position shewn at 2, 4, and 6, Figs. 5 and 6.
Rotary motion is imparted to the cams p and p' from some convenient moving
part of the loom.
I would have it understood that although I have shewn each pawl or lever ?
provided with only one pin, any required number of pins or teeth or a serrated
surface may be employed.
Having now described the nature of my said Invention, and described with the
aid of Drawings how the same may be carried into practice, I would have it
understood that I do not limit myself to the precise details or configuration of the
parts I have shewn as the same may be varied or modified without in any way
departing from the nature of my said Invention; but what I do claim is,―
First. The arrangement, construction, and application of the grippers having
a pawl or lever l, with a relieving piece or guage n, also a pin m or its equivalents
forming my improvements in temples, substantially as and for the purpose herein
set forth.
Second. The general arrangement and application of the parts for imparting and
transmitting the various motions to the grippers forming the temples, and mere
modifications of such parts, substantially as herein set forth.
In witness whereof, I, the said John Hardaker, have hereunto set my hand
and seal, this Fifth day of June, in the year of our Lord One thousand eight
hundred and eighty two.
JOHN HARDAKER. (L.S.)
