CERTAIN IMPROVEMENTS. AOMING TEMPLES FOR LOOMS
Year: 1869

page_text: LETTERS PATENT to John Elce, of the City of Manchester, in the
County of Lancaster, Machine Maker, and Richard Bond, of the
same Place, Foreman, for the Invention of "CERTAIN IMPROVEMENTS.
AOMING TEMPLES FOR LOOMS"
PROVISIONAL SPECIFICATION left by the said John Elce and Richard
Bond at the Office of the Commissioners of Patents, with their
Petition, on the 5th August 1869.
WC, JOHN ELCE, of the City 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 such spiked rollers with loose segments con-
nected to a fixed axle instead of making them solid rollers, or with
segments on a revolving axle as heretofore. The spiked segments are

page_text: guided at one end by a recess in the adjustable blocks or heads screwed
to the transverse bar, and the other end in a collar which is screwed to
the fixed axle. Both the blocks and collars are provided with a
projection or cam, by which a lateral or expanding motion is imparted
to the segments as they are carried round by the fabric in the loom,
thereby stretching the fabric before it is taken over the breast beam and
relieving the strain upon the reed. The spiked segments are made of
malleable cast metal or of drawn steel tubes cut longitudinally.
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 4th February 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
ELCE, of the City 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 Fifth day of August, in the year
of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and suc.
cessors, 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, administrators, and assigns, or such others as we, the said
John Elce and Richard Bond, 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 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 Looms," upon the condition (amongst others) that we, the said John
Elce and Richard Bond, our executors or administrators, by an instru-
ment 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

page_text: Patent.
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.
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 such spiked rollers with loose segments con-
nected to a fixed axle instead of making them solid rollers or with
segments on a revolving axle as heretofore. The spiked segments are
guided at one end by a recess in the adjustable blocks or heads screwed
to the transverse bar, and the other end in a collar which is screwed to
the fixed axle. Both the collars are provided with a projection or cam,
by which a lateral or expanding motion is imparted to the segments as
they are carried round by the fabric in the loom, thereby stretching the
fabric before it is taken over the breast beam and relieving the strain
upon the reed. The spiked segments are made of malleable cast metal,
or wrought iron, or steel, or other suitable metal or material, or of drawn
steel tubes cut longitudinally.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to described the accompanying
Sheet of Drawings, reference being had to the figures and letters
marked thereon.
Figure 1 represents a pair of self-acting temples constructed according
to our improvements; Figure 2 is an end view of the same; Figure 3
is a plan, Figure 4 a longitudinal section, and Figure 5 a transverse
section of one of our improved temples.
In Figure 2a is a section of the breast beam of the loom; b, b, in
Figures 1 and 2 are the brackets, with studs c for supporting the transverse
bar d, to which the adjustable blocks or heads e, e, are fixed by set screws;
these parts are made in the ordinary manner. To each block or head e
is fixed an axle f supporting the spiked segments g; near the end of the
axle fis fixed a collar h; the ends of the segments are set down and
fit into recesses in the block e aud in the collar h, and both the blocks
and collars are provided with projections e¹ and ' against which the
shoulders on the spiked segments act; these projections are placed in
the requisite positions for giving a lateral to-and-fro motion to the
spiked segments. Each temple is provided with a semicircular cover i,

page_text: the object of which is to guide the fabric on to the spiked segments
when they are near to each other, that is to say, when the projections e¹
on the blocks e have moved the segments into the recesses in the
collars h, but as the fabric continues to be taken up, the segments being
carried round on the fixed axles fare gradually moved asunder to
expand the fabric by the projections h¹ on the collars h; these projec-
tions are so placed that the fabric is at its greatest tension when passing
over the top of the temple. As the fabric descends towards the bottom
of the covers i the segments again gradually approach each other to
release the fabric and to allow it to be drawn off the spikes when
passing to the edge of the cover. The spiked segments may be made of
ordinary wrought iron or steel, or of malleable cast iron or other suitable
metal, or of wood or other material, or of drawn steel tubes cut longi-
tudinally.
Having thus stated the nature of our Invention, and described the
manner of performing the same, we wish it to be understood that we do
not intend to claim any of the parts forming our improved self-acting
temples when taken separately; but what we do claim is, the improved
self-acting temples described, in which spiked segments revolve and
move laterally to and fro on fixed axles.
In witness whereof, we, the said John Elce and Richard Bond,
have hereto set our hands and seals, the Second day of February
One thousand eight hundred and seventy.
