page_text: Improvements in Braiding Machines.
I, JULES LAMI, of 31, Boulevard Henri IV, Paris, in the Republic of France, Lace
Manufacturer, 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 machines for making braid, stay and other laces and the
like, the object being to simplify the construction of such machines, to render them
stronger and firmer when in operation, to enable them to work at a high rate of speed
without risk of injury, and consequently to minimise the outlay for repairs.
In order to enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing in which
Figure 1 is a front elevation, and
Figure 2 is a side elevation of a braiding-machine constructed according to my
invention.
Figure 3 is a vertical section of a portion of the machine showing two of the
carriers for impelling the racers or bobbin holders, the section being taken through the
line b of
Figure 4 which is a plan view showing the race-circles in the upper platform of a
machine having four carriers.
Figure 5 is an elevation of one of the racers with its bobbin.
Figure 6 is a horizontal section on the line d of figure 5.
Figures 3 to 6 are drawn to a larger scale than figures 1 and 2.
Similar letters in all the figures indicate similar parts.
The machine is constructed with four platforms A M L and I, as shown in figure 3.
In the platforms A and M are cut the race circles N, N in which travel the racers
carrying the bobbins P, figure 5.
The racers are each constructed of a flat tube F fixed to a plate O¹ and provided
with a flat weighted spindle shown partly in full lines and partly in dotted lines in
the said figure 5. The spindle works in the tube F and its movement is limited
by a pin fixed thereto and working in a slot in the tube. The upper end of the
spindle, also of a flat shape, is provided with an eye through which and through a hole
n the top of a round tube O, the thread passes before leaving the racer.

page_text: The round tube O is fixed to a vertical extension Q of the plate O' on which the
bobbin P formed with teeth on its top part bears as it rotates.
Through this extension Q and also through a hole in a projection Q₁ thereon the
thread passos from the bobbin P previous to its passing through the eye in the
spindle f.
The extension 0 carries a forked pawl Q₁ which engages in the teeth of the
bobbin P.-As the race circles N isolate the portions A¹ from the rest of the platform,
the said portions are firmly connected to the frame by means of central pins J passing
through square passages b made therein.
The racers are caused to travel through the complete circuit formed by the race
circles N by means of the carriers B C D E, in the recesses G of which the racers
work, the projecting portions serving to impel the racers.
The fixed pins J are supported in the lower platform or base 1 of the machine and
the carriers B C D E revolve between the platforms A and M the latter being
connected to the platform L by two cylindrical portions or bosses L".
The carriers are operated by gearing K, K, driven from any suitable source
of power.
By this means the carriers are caused to easily impel the racers through the whole
circuit of the race circles and the threads are held in tension by the weighted spindles
of the racers which also keep the racers in proper equilibrium at whatever rate
the machine may be working.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. In a braiding-machine the means substantially as hereinbefore described with
reference to figures 5 and 6 for maintaining the tension of the threads.
2. In a braiding-machine the employment of race-carriers constructed as described
with reference to figures 3 and 4 in combination with suitably arranged race circles.
3. The improved apparatus consisting of the parts constructed and combined
substantially as described with reference to the accompanying drawing and operating
as and for the purpose described.
