IMPROVEMENTS IN THE MANUFACTURE OF CARRIAGES EMPLOYED IN MACHINES FOR THE MAKING OF LACE OR OTHER FABRICS
Year: 1863

page_text: LETTERS PATENT to James Carver, of the Firm of Messieurs Carver and
Mosley, of "The Butcher Street Works," in the Town and County of the
Town of Nottingham, Bobbin and Carriage Manufacturers, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF CARRIAGES EMPLOYED
IN MACHINES FOR THE MAKING OF LACE OR OTHER FABRICS."
Sealed the 25th September 1868, and dated the 30th March 1863.
PROVISIONAL SPECIFICATION left by the said James Carver at the
Office of the Commissioners of Patents, with his Petition, on the 30th
March 1863.
I, JAMES CARVER, of the Firm of Messieurs Carver and Mosley, of "The
Butcher Street Works," in the Town and County of the Town of Nottingham,
Bobbin and Carriage Manufacturers, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF CARRIAGES EMPLOYED
IN MACHINES FOR THE MAKING OF LACE OR OTHER FABRICS," to be as follows:-
Heretofore in carriages employed in machines for the manufacture of lace
or other fabrics, the springs placed in them for holding the bobbius in place
have been fixed in the carriages at about the centre of the bobbins, which
arrangement has necessitated a spring in each carriago of considerable length,
and has thereby rendered the bobbin liable to project irregularly over the side
of the carriage, and has occasioned damage to the lace or fabric, and loss of
time; moreover, in such carriages the space between the root of the spring of
the carriage and the bobbin has rendered the knots, burs, or other uneven

page_text: surfaces on the material wound on the bobbins liable to drag or impede the
revolution, causing instantaneous breakage of the thread, and it becomes in-
expedient to wind the bobbins full of thread, or even nearly so, by reason of
the thread dragging at the before-mentioned open space of the carriage.
Now, the object of my Invention is to remedy these defects; for this
purpose I fill up the open space in the carriage by using a larger bobbin, and
I place the spring on the top part of each carriage instead of at the side
thereof as heretofore, so that when the tops of the carriages are pressed by the
warp threads, the springs will hold the bobbins perfectly in the centre of the
carriages, and thus prevent the warp threads from entering the bobbins; the
space between the carriage and the bobbin being thus filled up, the size
of the carriage can be reduced and more lead can be given to the carriage.
This arrangement also allows of a larger bobbin than heretofore being placed
in a carriage of any required size, upon which bobbin an increased quantity of
material may be wound, thereby producing lace pieces of greater length than
beretofore produced with bobbins in carriages of equal dimensions.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Carver in the Great Seal Patent Office on the 30th
September 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
CARVER, of the Firm of Messieurs Carver and Mosley, of "The Butcher
Street Works," in the Town and County of the Town of Nottingham, Bobbin
and Carriage Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing dato the Thirtieth day of March, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Carver, Her special licence, that I, the said James Carver,
my executors, administrators, and assigns, or such others as I, the said James
Carver, 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 THE MANU-
.PACTURE OF CARRIAGES EMPLOYED IN MACHINES FOR THE MAKING OF LACE OR OTHER
FABRICS," upon the condition (amongst others) that 1, the said James Carver,

page_text: my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 Scal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said James Carver, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the follow-
ing statement, reference being had to the accompanying Drawings, and to the
Ictters and figures marked thereon, that is to say:
Heretofore in carriages employed in machines for the manufacture of lace
or other fabrics, the springs which hold the bobbins in place have been fixed
at the side of the carriages at about the centre of the bobbins, which arrange-
ment has necessitated the use of springs of considerable length, thus rendering
the bobbins liable to lean or project over the side of the carriages, so that the
warp threads become likely to enter the bobbins, and so occasion injury to the
lace or fabric, and loss of time; and, morcover, in the said arrangement as
heretofore used, a space being necessarily left in the carriage between the
bobbin and the root of the spring, knots, burrs, or other unevennesses of the
thread or material wound on the bobbin become liable to drag or impede
its revolution, and thereby cause instantaneous fracture of such thread or
material, so as to render it inexpedient to wind the bobbins full of thread, or
even nearly so, in consequence of the thread dragging at the before-mentioned
space.
Having thus stated the defects of the known arrangement heretofore used,
I proceed to state that tho object of my Invention is to remedy these defects.
and for this purpose, according to my improved arrangement, I fill up the
aforesaid open space by using in a carriage of any given size a larger. bobbin
than has heretofore been used in a carriage of such size, and I place the spring
at the top part of the carriage, or nearly so, instead of at the side thereof as
heretofore, so that when the tops of the carriages are pressed by the warp
threads, the springs will keep the bobbins perfectly upright in the carriages,
thus preventing the warp threads from entering the bobbins; the space
between the carriage and the bobbin being thus filled up, the size of the
carriage can be reduced, and "more lead" (as it is called) can be given to
the carriage.
My improved arrangement also allows of the employment in a carriage (of
any required size) of a larger bobbin than has heretofore been used (in a

page_text: carriage of such size), and as upon such larger bobbin a larger quantity of
thread or material can be wound than on a smaller bobbin, pieces of lace
or fabric can be produced of greater length than could have hitherto been
produced with bobbins in carriages of the same dimensions under the old
arrangement.
Having thus set forth the nature of my said Invention, I proceed more fully
to describe the manner of performing the same with reference to the accom-
panying Drawings.
Figure 1 represents a carriage according to the known arrangement here:
tofore used, having an ordinary long spring disposed as heretofore for holding
the bobbin; Figures 2 and 3 refer to my Invention, and shew my improved
arrangement, wherein I use a spring placed and arranged according to my
Invention, which enables me to use in a carriage of any required size a larger
bobbin than hitherto used in a carriage of such size. In Figure 2 the spring
is pointing upward, in Figure 3 it is reversed or pointing downward.
A is the carriage; B, the bobbin; and C, the spring, which is shewn in
my improved arrangement, Figures 2 and 3, as a short spring placed at the
upper or top part of the carriage, instead of being a long spring placed at the
side as heretofore.
In carrying out my arrangement I sometimes use a double spring with
crank fastening, and tho fulcrum of the spring may be perpendicular to the
centre of contact with the bobbin, and also to the centre of the verge of the
carriage, and to the centre of the bottom of the carriage. By my improved
arrangements I obtain a better method of fastening the spring in the carriage.
My method may be applied to any ordinary carriage in either rotary or Lover's
machines. Among the advantages of my Invention I may mention that in
my improved arrangement I obtain a central support and stay to the bobbin
and a direct action of the spring; moreover, the spring being fastened nearly
at the top of the carriage will hold the bobbin evenly and accurately and per-
fectly upright in the carriage, and there is less liability of the spring shifting
after having been once set; also more space is afforded for the bobbin, without
reducing the strength of the carriage; also the spring in my arrangement,
pressing less strongly into the bobbin by reason of its position than the spring
in the ordinary arrangement, admits of more thread being wound on a bobbin
than heretofore.
Having now described the nature of the said Invention, and in what manner
the same may be performed, I declare that I claim the improvements herein-
before described, according to which the spring which holds the bobbin in the
carriage is placed at the upper part thereof, and whereby in a carriage of any

page_text: given size a larger bobbin can be used than heretofore employed in a carriage
of such size, as described.
In witness whereof, I, the said James Carver, have hereunto set my hand
and seal, this Twenty-eighth day of September, in the year of our Lord
One thousand eight hundred and sixty-three.
