I EDWARD GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex,
Fellow of the Institute of Patent Agents do hereby declare the nature of said
Invention for "IMPROVEMENTS IN BRAIDING MACHINES (A communication to me
from abroad by John Andrew of Birmingham in the County of New Haven, and
State of Connecticut, Machinist and Engineer, and Thomas Forsyth Stevenson of
49 Saint Marks Avenue in the City of Brooklyn, in the County of Kings and State
of New York, Machinist and Engineer, both in the United States of America) to be
as follows:
In braiding machines the puppets or spindles that carry the bobbin are directed
in their courses through the race circles formed of the slotted guide plates by
turning shafts with projections upon them termed winglets or directors; these
winglets are between the upper and lower plates and pivotted at their ends in
recesses or holes in such plates.
These winglets are turned to guide the puppets, and they are subjected to sudden
movements and they are liable to rebound in cases where the speed is increased
beyond an established rate.
If the winglet rebounds or partially turns, the puppet moving in one direction is
liable to be brought into collision with that going in the other direction.
These improvements are for holding the winglets in their proper positions and at
the same time allowing them to turn freely to direct the puppets as they are moved
along through the slotted plates known as the race circles.
The plates and the winglet are the same as ordinarily used in braiding machines
except in the particulars hereafter indicated.
The winglet has projecting guides and the cam arms, and at the ends of the
connecting shaft are the pivots or arbor; these all being of ordinary construction
do not require further description.
In these plates are the holes or cylindrical recesses for the pivots of the winglets
but instead of these holes being of a size to fit the pivots each hole is bored out say

page_text: in the upper plate sufficiently large to receive a helical spring. This spring is of a
length greater than the length of the pivot, and of an internal diameter adapted to
receive such pivot.
It will now be understood that when the winglets are introduced into place
between the plates with a spring around each pivot that such springs will be
slightly compressed and act end wise upon the winglet and produce a slight friction
against the hub of the upper projecting guide, and of the hub of the lower guide
upon the lower plate, hence such winglets although partially turned in the usual
manner will not be subject to any rebound or falso motion in consequence of the
inertia of the winglet, and the speed of the machine can be greatly increased
without risk of the parts becoming misplaced.
This friction spring occupies but little space, the machine does not have to be
changed, except to enlarge the holes for the pivots, and the wear of the pivots is
less because the spring is similar to a loose bushing to the pivot, hence the efficiency
and durability of the machine are augmented.

I, EDWARD GRIFFITH BREWER of 33, Chancery Lane in the County of Middlesex,
Fellow of the Institute of Patent Agents do hereby declare the nature of said
invention for " IMPROVEMENTS IN BRAIDING MACHINES" (A communication to me
from abroad by John Andrew of Birmingham in the County of New Haven and
State of Connecticut, Machinist and Engineer, and Thomas Forsyth Stevenson of
49, Saint Marks Avenue in the City of Brooklyn in the County of Kings and State
of New York Machinist and Engineer both in the United States of America) and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
In braiding machines the puppets or spindles that carry the bobbins are directed
in their course through the race circles formed of the slotted guide plates by turning
shafts with projections upon them termd winglets or directors.
These winglets are between the upper and lower plates and pivoted at their
ends in recesses or holes in such plates.
These winglets are turned to guide the puppets and they are subjected to sudden
movements and they are liable to rebound in cases where the speed is increased
beyond an established rate. If the winglet rebounds or partially turns, the puppet
moving in one direction is liable to be brought into collision with that going in the
other direction.
These improvements are for holding the winglets in their proper positions and
at the same time allowing them to turn freely to direct the puppets as they are
moved along through the slotted plates known as the race-circles.
In the drawing
Fig. 1. is an elevation of one of the winglets of a braiding machine with the plates
in section and
Fig. 2. is a plan of the winglet.
The plates a. and b. and the winglet c. are the same as ordinarily used in braiding
machines except in the particulars hereafter indicated.
The winglet has the projecting guides 1. 2. and the cam arms 3. 4. and at the
ends of the connecting shaft are the pivots or arbors 5. 6: these all being of
ordinary construction do not require further description.
In the plate a. are the holes or cylindrical recesses for the pivots 5. of the
winglets but instead of these holes being of a size to fit the pivots, each hole is
bored out sufficiently large to receive the helical spring : this spring is of a
length greater than the length of the pivot 5, and of an internal diameter adapted
to receive such pivot.
It will now be understood that when the winglets are introduced into place
between the plates a. b. with a spring i. around each pivot 5. that such springs i.
will be slightly compressed and act endwise upon the winglets and produce a
slight friction against the hub of the projecting guide 1. and of the hub of the
guide 2. upon the plate b. hence such winglets although partially turned in the
usual manner will not be subjected to any rebound or false motion in consequence
of the inertia of the winglet and the speed of the machine can be greatly increased
without risk of the parts becoming misplaced.

page_text: This friction spring i. occupies but little space, the machine does not have to be
changed except to enlarge the holes for the pivots 5. and the wear of the pivots is
less because the spring is similar to a loose bushing to the pivot, hence the efficiency
and durability are augmented.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim as the invention communicated to me is
First. The combination with the plates a. and b. in a braiding machine, of the
winglets between such plates, and a helical spring i. around one pivot of each
winglet, the recesses or holes for the pivots being enlarged to receive the helical
springs as specified.
Second. The combination with the winglets in a braiding machine of springs
applied to prevent false motion or rebound, substantially as set forth.
