CERTAIN IMPROVEMENTS IN SELF-ACTING TEMPLES FOR LOOMS
Year: 1870

page_text: LETTERS PATENT to John Elce, of Manchester, in the County of
Lancaster, Machine Maker, and Richard Bond, of the same Place,
Foreman, for the Invention of "CERTAIN IMPROVEMENTS IN SELF-ACTING
TEMPLES FOR LOOMS."
Sealed the 28th June 1870, and dated the 1st January 1870.
PROVISIONAL SPECIFICATION left by the said John Elce and Richard
Bond at the Office of the Commissioners of Patents, with their
Petition, on the 1st January 1870.
WC, JOHN ELCE, of Manchester, in the County of Lancaster, Machine'
Maker, and RICHARD BOND, of the same Place, Foreman, do hereby
declare the nature of the said Invention for "CERTAIN IMPROVEMENTS IN
SELF-ACTING TEMPLES FOR LOOMS," to be as follows:-
Our Invention relates to the temples known as spiked roller temples,
and it consists in making one or both ends of such spiked rollers with
cams or projections. On the face of the bearings in which the spiked

page_text: rollers revolve are other cams or projections, consequently as the rollers
are carried round by the fabric in the loom the cams or projections cause
the spiked rollers at each selvage to move endwise in opposite directions,
thereby distending the fabric and relieving the strain on the reed. The
number and arrangement of the cams or projections may be varied, and
the spiked rollers may be made of any suitable metal or material.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Elce and Richard Bond in the Great Seal
Patent Office on the 30th June 1870.
TO ALL. TO WHOM. THESE PRESENTS SHALL COME, we, JOHN 1
ELCE, of Manchester, in the County of Lancaster, Machine Maker, and
RICHARD BOND, of the same Place, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of January, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-third year 1
of Her reign, did for Herself, Her heirs and successors, give and grant
unto us, the said John Elce and. Richard Bond, Her special licence,
that we, the said John Elce and Richard Bond, our executors, adminis-
trators, and assigns, or such others as we, the said John Elce and Richard
Bond, our executors, administrators, and assigns, should at any time 2
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"CERTAIN IMPROVEMENTS IN SELF-ACTING TEMPLES FOR Looxs," upon the con-
dition (amongst others) that we, the said John Elee and Richard Bond,
our executors or administrators, by an instrument in writing under our,
or their, or one of our or their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
14:
NOW KNOW, YE; that we, the said John Elce and Richard Bond, do
hereby declare the nature of our said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say) :-
Our Invention relates to the temples known as spiked roller temples,
and it consists in making one or both ends of such spiked rollers with
cams or projections. On the face of the bearings in which the spiked
rollers revolve are other cams or projections, consequently as the rollers
are carried round by the fabric in the loom the cams or projections cause
the spiked roller at cach selvage to move endwise in opposite directions,
thereby distending the fabric and relieving the strain on the reed. The
number and arrangement of the cams or projections may be varied, and
the spiked rollers may be made of any suitable metal or material.
And in order that our Invention may be fully understood we will
proceed to describe the accompanying Sheet of Drawings, reference
being had to the figures and letters marked thereon.
Fig. 1 is a plan of a pair of self-acting temples constructed according
to our improvements; Fig. 2 is an end view of the same; and Figs. 3
and 4 are detached views of one of the spiked rollers forming part of the
same. In Fig. 2, a is a section of the breast beam of the loom to which
our improved temples are applied; b, b, see Figs. 1 and 2, are the
ordinary brackets and studs supporting the cross bar c, to which the
bushes d, d, are fixed by set screws, so that the distance between the
temples may be regulated according to the width of the fabric that is
being woven. The bearings d¹, d², projecting from the bushes d support
the spiked rollers e, e, each of which is provided with a cover ƒ as in
ordinary temples. It is well understood that the selvages of the fabrics
are carried over the spiked rollers e, e, and as the fabric is carried
forward by the taking-up motion the spiked rollers revolve in their
bearings.
.
Now our Invention consists in the means whereby the spiked rollers
are moved endwise in opposite directions for the purpose of distending
the fabric and relieving the strain on the reed when the reed beats up.
This is effected in the following manner:-At each end of the spiked
rollers are three or other convenient number of cams or projections, and
cach of the bearings d¹ has a cam or projection on its upper surface, as
shewn best at the right-hand side of Fig. 1, while each bearing d² has a
corresponding projection below. By this means as the spiked rollers
revolve the cams or projections from the bearings d' acting on the cams

page_text: or projections on the inner ends of the spiked rollers force them asunder
to the extent required for distending the fabric, and the cams or pro-
jections on the bearings d² force the spiked rollers back again or towards
the bearings d', so that they may be in the proper position for distending
the fabric at the next revolution. In some cases the projections on the
bearings d may be dispensed with, as the strain of the fabric has a
tendency to hold the ends of the spiked rollers against the projection on
the bearings d¹.
Figs. 5 and 6 represent a modification of our Invention. In these
views the cam projecting from the bearing d¹ is made separate from the
bearing itself, and it is connected to the bearing by a set screw passing
through a segmental slot. By this arrangement the position of the cam
can be adjusted. The cam on the bearing d² may be constructed in the
same manner.
Having thus stated the nature of our Invention, and described a
convenient manner of performing the same, we wish to remark that we
do not limit ourselves to the number of the cams or projections on the
ends of the spiked rollers and on the bearings in which they revolve;
but what we do claim as our improvements in self-acting temples is, the
application of cams or projections to one or both ends of solid spiked
rollers acting against suitable cams or projections, either cast with or
fixed by set screws to the bearings in which they revolve, in the manuer
and for the purposes described.
In witness whereof, we, the said John Elce and Richard Bond,
have hereto set our hands and seals, this Twenty-ninth day of
June One thousand eight hundred and seventy.
