Year: 1874

page_text: LETTERS PATENT to Michael Mortimer, Manufacturer, and Daniel
Bateman, Card Manufacturer, both of Wibsey, near Bradford, in
the County of York, for the Invention of "IMPROVEMENTS IN LOOMS
FOR WEAVING."
COMPLETE SPECIFICATION filed by the said Michael Mortimer and
Daniel Bateman at the Office of the Commissioners of Patents,
with their Petition and Declaration, on the 30th June 1874,
pursuant to the 9th Section of the Patent Law Amendment Act,
1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MICHAEL
MORTIMER, Manufacturer, and DANIEL BATEMAN, Card Manufacturer,
both of Wibsey, near Bradford, in the County of York, send greeting.
ا.
WHEREAS we are in possession of an Invention for "IMPROVE-
MENTS IN LOOMS FOR WEAVING," and have petitioned Her Majesty to grant
unto us, our executors, administrators, and assigns, Her Royal Letters

page_text: Patent for the same, and have made solemn Declaration that we verily
believe ourselves to be the first and true Inventors thereof.
NOW KNOW YE, that we, the said Michael Mortimer and Daniel
Bateman, do hereby declare that the following Complete Specification,
under our hands and seals, fully describes and ascertains the nature of
our said Invention, and the manner in which the same is to be per-
formed, reference being had to the Drawing hereto annexed and forming
part of this Specification, and to the figures and letters marked thereon,
that is to say :—
This Invention relates to swivel looms in which small swivel shuttles
are employed to weave figures or patterns on a plain or figured ground,
and consists in improved arrangements for stopping the tappets while
the swivel shuttles are producing the pattern, and in starting the
tappets while weaving the ordinary plain or figured ground between
the patterns, or when weaving the ground during the process of
prodcing the pattern.
To make our Invention better understood we will proceed to describe
the same by reference to the accompanying Drawing, in which Figure 1
represents a side view of our improvements; Figure 2, back view;
Figure 3, plan of the same; Figure 4 represents a swivel shuttle fitted
with our improved break.
Directly the plain or figured ordinary ground parts are woven the
jacquard acts upon the chain or band A lifting the catch lever B and
forcing forward the clutch lever C, which lever actuates the clutch
box D cast on the plate E in which two studs F are fitted. This plate
and clutch box slide on the tappet shaft G, the studs enter openings I
formed in another plate J working on the tappet shaft G; one of these
studs is made to pass outside the plate J and actuates a lever K striking
it down as it revolves and pulling the chains L which pass over the
friction pullies M and which are attached to the fork levers N; these
levers work in clutch boxes O cast on the tappets P and slide on the
shaft G, the chains L being pulled back by the stud F striking the
lever K causes the fork levers N to pull back the clutch boxes O and
consequently throws the tappets P out of gear with the tappet boxes Q
stopping the ordinary ground shuttle, whilst the silk is picking and
throwing out every other pick when weaving figures. A spring R is
fitted to the clutch lever C to force forward the clutch box D and keep it

page_text: in position whilst the silk is picking. When the figures are woven the
jacquard acts on the chain or band G2 throwing back the clutch lever C
and bringing the catch lever B into gear with the catch plate H². A
spring I is fitted to a lever J³ fixed to the catch lever C to keep the
gear from moving when the ordinary ground shuttle is operating.
The pullies M are fitted on studs fixed in brackets S; the fork
levers N are fitted to stay rods T fixed to the loom frame, and have
springs U fitted to them to force back the fork levers N when the
tappets P are thrown into gear with the tappet boxes Q, putting the
ordinary ground shuttle in operation; breaks. V are fitted to the
tappets P to prevent them working forward or backwards when thrown
out of gear in weaving figures; a projecting lever W is fitted on the
neck of the clutch box O on which the weft fork lever works to stop
the loom when a weft or wefts break. On the clutch box D is cast or
fitted a spur wheel Y actuating a spur wheel Z in which are fitted on
each side of the spur wheel studs A¹ which in revolving come in contact
with the projecting bosses B' formed on the levers C₁ fitted on the
shaft D'; the levers C have an alternate up-and-down motion and have
attached to them at the ends bands E' which pass over friction pullies F¹
fitted to the gantree G¹; these bands E¹ pass under friction pullies Hand
are attached to the regulating screws I¹ fitted to the swivel rack J¹,
giving a forward and backward motion to the swivel rack J' in which
the swivel shuttles are fitted to weave the figures or patterns; the
shaft D' works in bearers K' fitted to the cross rails L'.
The spur wheel Z operates a spur wheel M¹ fitted on a shaft N¹
working in brackets O¹ fixed to the side frame P¹; the spur wheel M
actuates by means of the shaft N¹ a tappet Q¹ which operates on a
fricton wheel R' fitted on the lever S', giving an up-and-down motion to
the lever and actuating a rod T fitted on one end of the lever S¹; this
rod T¹ is fitted on a short lever U¹ fixed on the rack shaft V₁ on which
are fitted two eccentrics W¹; these eccentrics are formed with a flat
surface on which are fixed leather straps X'; these leather straps are
attached at the other end to the swivel rack J¹. The rocking motion
given to the rack shaft V₁ actuates the eccentrics W¹ and lifts up the
swivel rack J¹ and swivel shuttles out of the way of the ground shuttle
with its weft to be picked, and these latter are lowered for throwing in
the figure weft as and when required. On the lever S₁ is fitted a
bracket or rod Y¹ to which is attached a band Z¹; this band is fastened

page_text: to the setting up catch of the loom and prevents it from setting up
when weaving the figures. The rack shaft V¹ is fitted in brackets A²
fixed to the hand rail B2 of the going part C³, on one of these
brackets A² is fitted a catch D³ operating on a flat surface formed on
the rack shaft V₁; this catch D² is actuated by bands E² operated by the
jacquard, which bands lift the catch D³ and throw the rack shaft V¹
from flyer to flyer.
In the swivel shuttles (Figure 4) we fit brushes F2 acting as a break
or retarder and preventing the yarn or silk coming off slack; we can
use one brush or break instead of two.
Having thus described the nature of our Invention and shewn by
Drawings how the same is to be performed or carried into practice, we
would have it understood that we do not claim the propelling of a series
of shuttles by means of a rack, but what we do claim as our Invention
and intend to be protected is, the arrangements whereby we are enabled,
firstly, to stop the tappets while the swivel shuttles are producing the
pattern; and, secondly, to start the tappets while weaving the ordinary
plain or figured grounds between the patterns, or when weaving the
ground during the process of producing the pattern, substantially as
herein-before described and represented in the accompanying Drawing.
In witness whereof, we, the said Michael Mortimer and Danicl
Bateman, have hereto set our hands and seals, this Twenty-ninth
day of June, in the year of our Lord One thousand eight hundred
and seventy-four.
