IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1874

page_text: LETTERS PATENT to James Pickup, of Tong, near Bradford, in the
County of York, Engineer, for the Invention of "IMPROVEMENTS IN
LOOMS FOR WEAVING."
Sealed the 21st April 1874, and dated the 3rd February 1874.
PROVISIONAL SPECIFICATION left by the said James Pickup at
the Office of the Commissioners of Patents, with his Petition, on
the 3rd February 1874.
I, JAMES PICKUP, of Tong, near Bradford, in the County of York,
Engineer, do hereby declare the nature of the said Invention for " Im-
PROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
This Invention relates,―
Firstly. To an improved means of controlling the warp beam during
the "letting off" of yarn. This object I accomplish by means of a "clip
spring" or spring which embraces a considerable proportion of the
diameter of the neck or necks "or ruffle of the warp beam. The said
spring is made in the form of a strap, and its interior is lined or faced

page_text: with india-rubber leather; one end of such spring is received on a stud
fixed to the frame of the loom, the other end of the spring is connected
by chain or cord with the weight lever. In some cases the spring may
be formed of two parts and hinged so as to admit of one portion being
turned over or backwards to facilitate the removal and replacement of
the warp beam. The support stud which carries the clip spring above
described (where considerable power is required) is placed above the clip
spring so that its extremities may by means of crossed links attached to
the loose ends of the said spring, the weight applied tends to draw the
ends of the spring together, so embracing the neck or ruffle of the beam
and increasing the friction on the necks or ruffles thereon.
Secondly. The spiral springs used in connection with the working the
healds, picking shaft, and other parts of the loom I mount on wires or
rods passed through the interior thereof, and a ring is connected with
the internal wires at each end of the spring by having the end of each
wire curved over a cap or disc at each end of the spring.
Thirdly. In the use of india-rubber, buffer, or check pieces mounted
on the spindle of the shuttle box so as to break the shock of the picker
and to prevent the throw of grease and damaging with the check straps.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Pickup in the Great Seal Patent Office on
the 3rd August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
PICKUP, of Tong, near Bradford, in the County of York, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of February, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Pickup, Her special licence that
I, the said James Pickup, my executors, administrators, and assigns,
or such others as I, the said James Pickup, my executors, admi-
nistrators, and assigns, should at any time agree with, and no others,

page_text: 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 LOOMS FOR
WEAVING," upon the condition (amongst others) that I, the said James
Pickup, 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 Scal Patent Office within six cálendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Pickup, 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 and accompanying Sheet of Drawings, that is to say:-
This Invention relates,―
Firstly. To an improved means of controlling the warp beam during
the letting "off" of yarn. This object I accomplish by means of a
"clip" spring or springs which embraces a considerable portion of the
diameter of the neck or necks or "ruffle" of the warp beam. The said
spring is made in the form of a strap, and its interior is lined or faced
with india-rubber or leather; one end of such spring is received on a
stud fixed to the frame of the loom, the other end of the spring is con-
nected by chain or cord with the weight lever. In some cases the spring
may be formed of two parts and hinged so as to admit of one portion
being turned over or backwards to facilitate the removal and replace-
ment of the warp beam. The support stud which carries the clip spring
above described (where considerable power is required) is placed above
the clip spring so that its extremities may by means of crossed links
attached to the loose ends of the said spring, the weight applied tends to
draw the ends of the spring together, so embracing the necks or ruffle of
the beam and increasing the friction on the necks or ruffles.
Secondly. The spiral springs used in connection with the working the
healds, picking shaft, and other parts of the loom I mount on wires or
rods passed through the interior thereof, and a ring is connected with
the internal wires at each end of the spring by having the end of cach
wire curved over a cap or disc at each end of the spring.

page_text: Thirdly. In the use of india-rubber buffers or check pieces mounted
on the spindle of the shuttle box so as to break the shock of the picker
and to prevent the throwing of grease, and dispensing with the check
straps.
DESCRIPTION OF
Fig. 1 is a back elevation of a loom illustrating the first part of my
Invention; Figs. 2 and 3 are details or parts detached. On that end of 1
the loom nearest Fig. 2 is shewn a "clip" spring A, embracing a con-
siderable portion of the neck or "ruffle" of the warp beam B. In this
case the spring or clip is attached to the frame at one end by the stud C,
is hinged at D, and connected to the weight lever E by the rod E¹.
Fig. 2 fully illustrates the construction of this spring. At the other end 1
of the loom is shewn a spring or "clip" hinged above the warp beam
at F, and attached to the framework by the stud G; to the ends of the
spring are attached links H hinged at H³, the ends being connected by
chain and operated by the weight lever through the rod J, the tension
acting to draw nearer together the ends of the crossed links and so
increasing the friction on the necks or ruffles. This will be fully under-
stood by referring to Fig. 3.
Fig. 4 illustrates the second part of my Invention. The spiral spring K
is shewn mounted on rods or wires L, the ends of the said wires passing
through holes or slots in the caps or discs M fitting on to or against the
ends of the spring; the wires L are doubled or bent and are connected
to the healds, picking shaft, or other parts by cord passed through the
rings N on the bend or centre thereof, the ends being attached to the
discs either by bending them or otherwise. The wire or rod L being
attached to the disc M and the wire or rod L³ to the disc M¹ it will be
understood that tension exerted upon the rings N produces a corre-
sponding amount of compression on the spring by reason of the discs M
and M¹ being drawn towards each other.
Fig. 5 is a front view of part of the "lay" and shuttle box, and
illustrates the third part of my Invention. A is the picker spindle, on
the end of which is an india-rubber buffer or check piece B which serves

page_text: to break the shock of the picker in one direction, whilst the stop piece or
rod C hinged underneath the lay at D (and passing through a slot hole
cut therein) breaks the shock in the other direction by means of the
bent spring E against which it rests.
In witness whereof, I, the said James Pickup, have hereunto set
my hand and seal, this Thirtieth day of July, in the year of our
Lord One thousand eight hundred and seventy-four.
