Year: 1864

page_text: LETTERS PATENT to John Smith, of Leicester, Mechanic, for the Invention
of "IMPROVEMENTS IN BATTENS AND IN GEAR FOR COMMUNICATING THE TO-AND-
FRO MOTIONS TO THE DRIVING PLANKS OF BATTENS."
PROVISIONAL SPECIFICATION left by the said John Smith at the
Office of the Commissioners of Patents, with his Petition, on the 24th
October 1864.
I, JOHN SMITH, of Leicester, Mechanic, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN BATTENS AND IN GEAR FOR COMMUNICATING
THE TO-AND-FRO MOTIONS TO THE DRIVING PLANKS OF BATTENS," to be as
follows:―
My Invention consists in fitting levers upon a plate on the sole of the shuttle,
in forming guides upon the facing boards, and in providing notches in the
driving plank into one or other of which the levers are made to take in order
to the shuttle being carried across the warp. The levers are centred upon
studs on the sole plate, the long arm of the levers is bent and carries a friction
roller, and a spring acts upon the short arm to keep the long arm within the
shuttle, except when made to descend into the notch on the driving plank.
Upon the front of the shuttle reaching one side of its work the friction roller
of the front lever comes in contact with one of the guides on the facing plate,
and is thereby depressed and guided into one of the notches in the. driving.
plank, whereby the shuttle is carried forward, then the lever at the back of

page_text: the shuttle is forced up out of the other notch in the driving plank by another
guide in the facing plate, and is drawn within the shuttle by the spring acting
on the tail or short arm of the lever, and the shuttle is carried across the work.
On the return stroke of the driving plank that which was the back becomes
the front of the shuttle, and the action is similar to that just described, and
so on. Instead of notches being made in the driving planks pins may be
inserted, and apertures may be formed in the levers to fit over such pins.
My Invention also consists in an arrangement of gear for communicating
the to-and-fro motions to the driving planks of battens as shewn in the
accompanying Drawings.
A is the shaft on which the cam is mounted; B is the groove in the cam;
C is the roller fixed in the lever D, working in the groove of the cam; E is a
slot in the lever carrying an axle and universal joint connected to the driving
plank.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Smith in the Great Seal Patent Office on the 24th
April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SMITH, of Leicester, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of October, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Smith, Her special licence that I, the said John Smith,
my executors, administrators, and assigns, or such others as I, the said
John Smith, my 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 "IMPROVEMENTS IN
BATTENS AND IN GEAR FOR COMMUNICATING THE TO-AND-FRO MOTIONS TO THE DRIVING
PLANKS OF BATTERNS," upon the condition (amongst others) that I, the said John
Smith, my executors or administrators, by an instrument in writing under iny, or
their, or one of 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

page_text: Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said John Smith, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, reference being had to the Drawings hereunto annexed, that is to
say:-
My Invention consists in fitting levers upon a plate on the sole of the shuttle,
in forming guides upon the facing boards, and in providing notches in the
driving plank, into one or other of which the levers are made to take in order
to the shuttle being carried across the warp. The levers are centred upon studs
on the sole plate, the long arm of the levers is bent and carries a friction roller,
and a spring acts upon the short arm to keep the long arm within the shuttle
except when made to descend into the notch in the driving plank. Upon the
front of the shuttle reaching one side of its work the friction roller of the front
lever comes in contact with one of the guides on the facing plate, and is
thereby depressed and guided into one of the notches in the driving plank,
whereby the shuttle is carried forward, then the lever at the back of the shuttle
is forced up by the other guide out of the other notch in the driving plank,
and drawn within the shuttle by the spring acting on the tail or short arm of
the lever, and the shuttle is carried across the work. On the return stroke of
the driving plank that which was the back becomes the front of the shuttle,
and the action is similar to that just described, and so on.
Figure 1 of the accompanying Drawings is a front elevation, and Figure 2
a plan of a batten constructed according to my Invention showing the batten
thrown to one end of its race.
a is the shuttle, on the sole h of which I fit levers b, b'; c, c, are the facing
boards, which I form with guides d, d'; e, e¹, are notches in the driving plank f,
into one or other of which one or othor of the levers b, b', is made to take in
order that the shuttle a may be thrown across the warp. The levers b, b¹, are
centred on studs g, 9', on the sole plate h, the long arm of each lever is bent,
and formed with a pin i, or instead of the pin it may carry a friction roller; a
spring acts upon the short arm of each lever b, b', to keep the long arm
within the shuttle except when made to descend into the notch in the plank f.
When the shuttle a reaches one side of its work (say that towards the right of
the Figures), the pin i (or the friction roller) on the lever 6 on that side comes
in contact with the guide d on the same side, and is thereby depressed and
guided into the notch e, on that side of the driving plank whereby the shuttle
carried to the end of its race into the position represented in the Figure.

page_text: While the shuttle is being thus carried to the end of its race the pin i on the
other lever breaches the end of the guide d', and is forced up out of the.notch;
the spring ; then acts on the tail of the lever and draws it within the shuttle
until the pin reaches the other guide d, when it again enters the notch e¹. On
the return stroke of the driving plank the pin i of the lever is again drawn
within the shuttle by the spring ; until it has passed the work, when the guido
ď forces it again into the notch e¹ to carry the shuttle to the other end of its
race. In this return stroke the lever 6 is acted on in the same manner as the
lever b¹ in the stroke first described. Instead of notches being made in the
driving planks pins may be inserted in the planks and apertures may be formed
in the levers to fit over such pins. Figure 3 represents a lever for this purpose;
k, is the aperture to fit over the pin on the driving plank, and is a projection
on the lever to enter the guides d, d, on the facing boards.
My Invention also consists in an arrangement of gear for communicating
the to-and-fro motions to the driving planks of battens. A is the cam, and A',
the shaft on which it is mounted; B is the groove in the cam; C is the roller
fixed in the lever D working in the groove B of the cam; E is a slot in
the lever D carrying an axle F connected to a rod driver H by a rod G; the
connection of the driver H and rod G forms with the connection of the rod G
and axle F a universal joint; or the rod G may be connected to the bracket I
attached to the plank f.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, constructing battens with levers, guides, and notches or pins,
all acting substantially in manner and for the purpose berein-before described.
Second, arranging gear for communicating the to-and-fro motions to the
driving planks of battens in manner herein-before described and represented
in the accompanying Drawings.
In witness whereof, I, the said John Smith, have hereunto set my hand
and seal, this Twenty-first day of April, One thousand eight hundred
