PROVISIONAL SPECIFICATION left by the said Philip Goldschmidt
and James Chambers at the Office of the Commissioners of Patents,
with their Petition, on the 21st November 1874.
We, PHILIP GOLDSCHMIDT, of Manchester, and JAMES CHAMBERS, of
Bury, both in the County of Lancaster, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF SELF-ACTING
'TEMPLES' USED IN LOOMS FOR WEAVING, AND IN TOOLS OR APPARATUS EMPLOYED
IN SUCH MANUFACTURE," to be as follows:-
This Invention relates,-
Firstly. To the construction of what are known in the trade as

page_text: And, Thirdly. To a peculiar form of "chuck" to be used in the lathe
for cutting the segments of the latter class of temples.
The movable or acting part of the "square-nosed temple" as usually
constructed consists of a disc or flat wheel of metal (having pins pro-
jecting radially from its edge) which works on a vertical axis inside a
fixed case or box having a slot so formed as to guide the edge of the
cloth on to the pins.
We also employ a disc or wheel mounted on a vertical axis in a case or
box in a somewhat similar manner, but we provide the wheel with a
flange, and instead of fixing the pins in the edge of the wheel we fix
them vertically in the outer ends of a series of levers mounted radially
on the face of the dise and working in slots cut in the rim or flange.
These levers are provided underneath with projections, which pass
through slots in the disc and rest upon the bottom plate of the box as
the disc or whcel revolves. Over that side of the box where the selvedge
of the cloth passes we fix a plate, which prevents the edge of the cloth
from being raised, and on the bottom plate of the box or case we fix or
form an inclined plane, which as the disc revolves raises up each radial
lever and presses its pins up through the cloth, a groove being cut in the
under side of the top plate to receive the points of the pin. So long as
cach lever rests on the incline its pins will hold in the selvedge of the
cloth, but as each lever in turn passes off the incline it falls down and
releases its pins from the cloth, and so on in succession as the disc
revolves by the pull of the cloth.
The movable parts of the "segment temple" consist of rings of metal,
with pins projecting radially therefrom, running between fixed segments,
which are strung alternately with them on a central stud, the segments
being so formed that they lie at an angle (other than a right angle) to
the central stud or axis. In this class of temple as hitherto made the
segments and rings all lic at one and the same angle.
Our improvement consists in so forming the segments that they lic at
a gradually increasing angle towards the edge of the cloth, that is to
say, the segment at the end nearest to the centre of the cloth is nearly
at a right angle to the axis, and each segment in succession lies at an
increasing angle to the preceeding one, the one acting on the extreme a

page_text: edge lying at the most acute angle. By these means the temple pulls
with a strain, slight at first, but gradually increasing towards the
selvedge.
The "chuck," by means of which we cut the segments from a rod or
cylinder in the lathe, is formed with a segmental piece or quadrant and
a shoc by which it is connected to the face plate of the lathe. The
quadrant is movable on the shoe, so as to be capable of being set to any
angle required, and can be fixed in any position by means of a bolt
or bolts.
This quadrant is formed, with a clip or ring and screw for holding the
rod or cylinder from which the segments are to be cut, and it will be
evident that by altering the position of this segment with regard to the
shoe (and hence with regard to the face plate of the lathe) the rod or
cylinder can be held at any angle to the axis of the lathe cylinder, and
consequently the segments can be cut off at any required angle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Philip Goldschmidt and James Chambers in the
Great Seal Patent Office on the 20th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, PHILIP
GOLDSCHMIDT, of Manchester, and JAMES CHAMBERS, of Bury, both
in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of November, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eight year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Philip Goldschmidt and James
Chambers, Her special license that we, the said Philip Goldschmidt and
James Chambers, our executors, administrators, and assigns, or such
others as we, the said Philip Goldschmidt and James Chambers, our
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during
the term thorcin expressed, should and lawfully might make, use,

Our improvement consists in so forming the segments i, i, that they
lic at a gradually increasing angle towards the edge of the cloth, that is
say,
the segment at the end nearest to the centre of the cloth is nearly
at a right angle to the axis, and each segment in succession lies at an
increasing angle to the preceding one, the one acting on the extreme
edge lying at the most acute angle, as seen at Figs. 3 and 4. By these
means the temple pulls with a strain slight at first, but gradually
increasing towards the selvedge.
We would here remark that we prefer to place the pins in two rows,
as shown in the Drawing, as the cloth is less marked thereby than when
'the pins are all placed in one row. This is also applicable to the ordinary
segment temple. We also in some cases prefer to mount the segment
temple in a reversed position, that is, with the roller uppermost and the
trough beneath.
The chuck (see Figs. 5 and 6) by means of which we cut the segments
from a rod or cylinder in the lathe is formed with a segmental piece or
quadrant 7, 1, and a shoc m, m, by which it is connected to the face plate
of the lathe. The quadrant 1, 1, is movable on the shoc m, m, so as to
be capable of being set to any angle required, and can be fixed in any
position by means of a bolt or bolts n, n.
This quadrant is formed with a clip or ring o, o, and screw p, p, for
holding the rod or cylinder from which the segments are to be cut, and
it will be evident that by altering the position of this segment 1, 2, with
regard to the shoe m, m, (and hence with regard to the face plate of the
lathe) the rod or cylinder can be held at any angle to the axis of the
lathe spindle, and consequently the segments can be cut off at any
required angle, as shown by the red lines in Fig. 6.
Having now 'described the nature and object of our said Invention,
together with the manner in which the same is to be or may be performed
or carried into practical effect, we wish it to be understood that we claim
as our Invention,―
Firstly. The construction of "square-nosed temples" with loose levers,
substantially as herein-before described.
Secondly. The construction of "segment temples" with their sex-

page_text: And, Thirdly. The novel construction of "chuck," for cutting such
segments in the lathe, all substantially as herein-before described and
represented by the Drawings annexed.
In witness whereof, I, the said James Chambers (on behalf of
myself and the said Philip Goldschmidt), have hereunto set my
hand and seal, this Eighteenth day of May, in the year of our
Lord One thousand eight hundred and seventy-five.
