IMPROVEMENTS IN BOBBIN NET OR TWIST LACE MACHINES
Year: 1874

page_text: LETTERS PATENT to James Whitehouse, of the Town and County of
the Town of Nottingham, for the Invention of " IMPROVEMENTS IN
BOBBIN NET OR TWIST LACE MACHINES."
Sealed the 5th January 1875, and dated the 14th October 1874.
PROVISIONAL SPECIFICATION left by the said James Whitehouse at
the Office of the Commissioners of Patents, with his Petition, on
the 14th October 1874.
I, JAMES WHITEHOUSE, of the Town and County of the Town of
Nottingham, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BOBBIN NET OR TWIST LACE MACHINES," to be as
follows:-
I employ a levers machine of the usual construction, and attach sliding
bars paralell to the landing bars, carried by the brackets and joints of
the landing bars and catch bars. These sliding bars withdraw the landing
bars as they approach the metals, thus making a go-through of the

page_text: machine. The sliding bars may be operated by a cam or plate on one or
both standards, as is well understood by persons conversant with such
machines.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said James Whitehouse in the Great Seal Patent Office
on the 14th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WHITEHOUSE, of the Town and County of the Town of Nottingham,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Whitehouse, Her special license
that I, the said James Whitehouse, my executors, administrators, and
assigns, or such others as I, the said James Whitehouse, 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
BOBBIN NET OR TWIST LACE MACHINES," upon the condition (amongst others)
that I, the said James Whitehouse, my executors or administrators,
by an instrument in writing under my, 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 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 Whitehouse, 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, reference being had to the accompanving

page_text: sliding bars parallel to the landing bars carried by the brackets and joints
of the landing bars and catch bars. These sliding bars withdraw the
landing bars as they approach the metals, thus making a go-through
of the machine. The sliding bars may be operated by a cam or plate on
one or both standards.
DUA WINGS,
Figure 1 is a view at the right end of a machine constructed according
to my Invention, but without the levers which operate the catch bars.
Figure 2 is a sectional view of the machine.
Figure 3, a side view of the levers which operate the catch bars.
Figure 4 shews in plan portions of the front sliding landing bar, the
bearing trucks, and swing brackets.
Figure 5 is a sectional view of the front and back landing bars and the
joints which carry them.
Figure 6, a side view of the levers which operate the swing brackets.
Figure 7, a side view of the point bar lifting cams.
Figure 8, a side view of the knocking out cams; similar cams to these
are used to work the levers seen in side view at Figure 6.
The machine consists of the following parts:-At Figures 1 and 2 A
is the end standard, two of which are connected by four tie rails B; the
saddle C is secured to the centre front stay D and to the lower back
rail, the stay D being attached to the two front rails. Under the lower
front rail is secured a foot D¹ connected by a stretcher bar D² to the foot
of the back stay E, which is secured to the two back rails. There are
two intermediate stays F secured to the lower front and back rails.
The arrangement of the levers and apparatus for effecting the several
movements of the carriages, both in the front and back, being duplicates
of each other, it will suffice if I describe those in the front of the centre
of the machine only. G is the carriage; G¹, the catch bar, the feet of
which are hinged to rocking levers G³, the upper ends of which are
connected by links to the operating arms G³ on the catch bar spindle G*,
which also acts as an axle for the point bar levers. The rocking levers G*
are carried by arms secured on a rocking axle G³, which is provided at.
each end of the machine with other arms outside the standards, and
which are acted upon by a system of levers at each end of the machine,

page_text: at Figure 6, which carry trucks at their upper ends operated upon by
cams of the same shape as those seen in side view at Figure 8, the out-
ward movement of the brackets N', thus causing an endways movement
of the sliding bar N³, and an outward movement of the landing bars
upon the joints which carry them.
By a machine constructed as above described, instead of dragging the
carriages over stationary landing bars or plates, or over the solid bottoms
of combs, each of which cause considerable friction, which is obviated
by causing my new landing bars to move with the catch bars and
carriages, as herein-before described and illustrated in the Drawings
annexed.
In witness whereof, I, the said James Whitehouse, have hereunto
set my hand and seal, this Twelfth day of April, in the year of
our Lord One thousand eight hundred and seventy-five.
Witness,
H. W. GOUGH, C.E.,
Nottingham.
JAMES WHITEHOUSE. (L.S.)
