Improvements in Twisting Machinery for Making Gimp Twine.
1, ARTHUR JOHN BROOK, of the firm of Brook Brothers of 6 Rathbone Place,
Oxford Street, London, W., Upholsterer's Trimming Manufacturers, do hereby declare
the nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :
This invention relates to improvements in twisting machines for making gimp twine
such as used for upholsterer's trimmings and has reference to mechanism applied to
twisting machines of ordinary construction as well as to a modified construction of
flyer whereby gimp twine can be produced of finer quality than heretofore, while
using less covering material for the same.
In the accompanying drawings Fig. 1 is a cross section of a portion of a twisting
machine provided with my improvements. Fig. 2 is a front view of the same.
Fig. 3 is a front view at an enlarged scale of my new mechanism detached from the
machine. Fig. 4 is a side view of the said mechanism partly in section on line
of Fig. 3.
l
The improved mechanism shown separately in Figs. 3 & 4 consists of a small slotted
plate H forming a bracket with the vertical plate I which is fixed to the former in any
suitable manner. Through the slot of the plate H passes a bolt m which is screw
threaded at its free extremity and secured at the other to a block or guide G, the
latter being furnished with a central groovey. The free extremity of the bolt mis
passed in order to attach the apparatus to the twisting machine or frame F, through
a slot y formed in the upper rail R of the said frame (Figs. 1 & 4). The vertical
plate I is also slotted to allow of the pulley carrier plate J being fixed thereto by a
bolt and a nut. In the plate J are fixed the screw threaded ents of two axes
furnished with a screw head and upon which the pulleys p p are free to rotate. The
guide G is provided with a tension wire or spring fixel thereto at one end as shown,
and with a guiding wire or hook g fixed at the upper end of the same. A series of
consecutive loops are formed in a wire frame L arranged in the manner shown and
attached by the ends of its lower and horizontal arm to the bolt m. My improved
flyer shown in Fig. 1 is formed as usual with two arms and and a head u the latter
and the arm i being furnished according to this invention with wheels or pulleys w w
respectively, while a depression is formod at to serve as a guide for the gimp
twine Z.
Fig. 1 shows a general view of a sufficient portion of a twisting machine or frame as
is necessary to fully illustrate the application of my invention thereto.
B is the bobbin supplying the cord designed to form the core of the gimp twine.
This bobbin is kept in position by the cord or catgut a fixed thereto at one end
passing over the small pulley d and attached at the other end to a spring & secured
to the hook bolt a the tension of the springs being regulated by the thumb screw s'.
P P¹ are grooved pulleys mounted the first above the other upon a suitable spindle
carried by the frame of the machine in the usual manner P being a loose and P¹ a
fixed pulley. T is a table carrying the creels e e upon which are mounted the reels bb.
Upon these reels are wound the threads or fibres ff which serve to form a covering
upon the cord or core e and hence to produce the gimp twine Z. S is the spindle
carrying the flyer N and the bobbin B' upon which is wound the covered or finished
gimp twine Z. The lower part of the bobbin B' is fixed to a whorl o mounted upon
the copping rail R' as usually effected in twisting frames, the said bobbin having also
an up and down motion on the spindle S. Motion is imparted in the ordinary manner
by the motor shaft to the whorl o and to the axis A of the pulley P. During such
motion the cord c is unwound from the bobbin B, passes over the various grooves of
the pulleys P and P¹ issuing finally from the last named pulley in order to pass over

page_text: and between the small pulleys pp. From the latter pulley the cord c passes over the
central groovey of the guide G and is covered in this groove by the fibres ff pro-
ceeding from the reels, band passing through the loops of the wire frame L
and through the space ẞ (Fig. 4) formed between the hook g and tension wire t.
The covered or finished gimp twine issues from the lower part of the guide G, passes
successively over the wheels or rollers of the flyer N in order to be finally wound
by the latter upon the bobbin B¹.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what
I claim is.
:
1. The application to twisting machines or frames employed for making gimp
twine and the like for upholsterer's trimmings of a device or mechanism arranged,
constructed and operating substantially as described and shown in Figs. 3 and 4 of the
drawings and for the purpose set forth.
2. In twisting machines or frames such as above mentioned the improved con-
struction of flyer shown in Fig. 1 substantially as and for the purpose set forth.
