We, JOSIAH GIMSON, and GIMSON AND CO. (LEICESTER) LIMITED of The Engine
Works, Vulcan Street Leicester in the County of Leicester Engineers do hereby
declare the nature of this invention to be as follows:-
This invention refers to improvements in or relating to braiding machines or
what is known as "narrow braid" or "dollys" wherein a series (according to the
number of strands desired) of heads revolve in alternate directions to wrap or
encircle a rubber thread or threads in making narrow flat braids, each head is cast
with a gear wheel at the bottom, grooved collars near either end, and a holow tube
or "rubber spindle" at the top, in each of the grooves are placed pipes carrying
tensioned bobbins of the silk, cotton, or other thread, all of which are of the same
diameter or circumference except the ones at each end, the said grooves number
four, five and upwards regularly disposed around and through the collars, the
larger number being employed in making fancy flat braids; hitherto only one
predetermined number of strands could be made upon one machine. The object
of this invention is to produce on one machine any number of strands up to sixteen
or more by altering or transferring the heads, and adding or diminishing the
number of heads as may be from time to time requisite to produce the desired
number of strands, and also means for knocking out or stopping such altered heads.
To carry out this invention plates are cast of a suitable size and shape, the heads
formed as before stated are geared together in a horse shoe frame in which are the
desired number of circular head holders, into which are placed bushes, in sections,
thus allowing of the heads to be changed, the said circular head holders admit of
the heads working freely therein. The change in the motion to the heads is caused
by the two outside heads having one more groove than the others as usual.
For making the number of strands required each head can be transferred from
one to the other of the circular head holders, and the dogs (which change the
courses of the pipes) are also removable and have a lip on the back thereof, and a
spindle thereto, so allowing them to be removed from the plates, without having
to take the plates to pieces as is now the case. The heads having being altered are
controlled by a shifting hand lever capable of adjustment thereto. The other parts
of the machine are constructed in the ordinary well known manner.
Dated this 24th day of November 1896.

page_text: We JOSIAH GIMSON, and GIMSON AND CO. (LEICESTER) LIMITED of The Engine
Works, Vulcan Street Leicester in the County of Leicester Engineers 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 refers to improvements in or relating to braiding machines or
what is known as "narrow braid" or "dolly's" wherein a series (according to
the number of strands desired) of heads revolve in alternate directions to wrap or
encircle a rubber thread or threads in making narrow flat braids, each head is
cast with a gear wheel at the bottom, grooved collars near either end and a hollow
tube or "rubber spindle" at the top, in each of the grooves are placed pipes
carrying tensioned bobbins of the silk cotton or other thread, all the grooved
collars are of the same diameter or circumference except the end ones and the
grooves in said heads number four, five and upwards regularly disposed around
and through the collars, the larger number being employed in making fancy flat
braids, hitherto only one predetermined number of strands, could be made upon
one machine.
The object of this invention is to produce on one machine any number of strands
up to sixteen or more by altering or transferring the heads B or B2, as may from
time to time be necessary to produce the desired number of strands, and also means
for knocking out or stopping such altered heads.
That the Invention may be clearly understood a sheet of drawings is annexed
in which
Figure 1 is a plan view looking from the top of the machine and is intended to
shew the arrangements fitted thereon for carrying out the invention.
Figures 2 and 3 show the form of bushes or wedges 1 and 2 employed in the top
plate A of the machine, the lower tongues thereof 13, and 2 fitting the small
heads B, and the upper tongues 1b and 2b fitting the larger heads B. It will be
observed on the left hand side of Figure 1 that the bushes 1 and 2 are fitted
opposite each other and are removable at any time.
Figure 4 shows one of the wedges 3 employed in the lower plate A', having only
one tongue, this is owing to the lower plate (not seen) being flat, and Figure 5
shows one of the dogs E employed between the heads to change the courses of the
pipes.
In carrying out this invention plates A and A¹ are cast to a corresponding size
and shape, with the horse shoe circle of holes B carrying the heads B and B made
as before described, and geared together below the lower plate A. In grooves
cut in the circular head holders C C "in left hand side of Figure 1" are fitted
the wedges 1 and 2 each having tongues 1 and 2, also 1 and 2, for the purpose
as hereinbefore stated and the bottom plate being flat the wedges 3 are used, of
the same size and shape has 1 and 2 but having only one tongue 3" as seen in
Figure 4. These sections are fitted as seen in Figure 1, and allow of the small
heads B being fitted in the larger circles, the spindles d carrying the larger
heads B2 are movable in oblong slots "see dotted lines "6" "Figure 1." which are
made in the lower plate A¹.
The change in the motion to the heads is carried out in the ordinary manner,
the outside heads B3 having one more groove than the others. Between the
heads are fitted dogs E Figure 5 which are of the ordinary character except that
lips 5 are provided, slotted to receive pins or screws 6, see right hand side of

page_text: Figure 1" so that they can be removed at will without having to remove the top
plate as is now the case. After the heads have been altered and secured in their
places they are controlled by an ordinary shifting hand lever (not
shown) capable of adjustment thereto. We would have it understood
that the letters of reference employed in the drawings indicate ordinary parts of
the machine and the figures those parts forming the subject of this invention.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is:-
The herein described means and contrivances for carrying out the alteration or
transfer of the heads in a braiding machine so as to produce on one machine anv
number of strands, with reference to Figures 1 to 5 of the accompanying
drawings.
