COMPLETE SPECIFICATION.
Improvements in Braiding Machines.
We, HENRY JANSSEN and FERDINAND THUN, both residents of the City of
Reading, State of Pennsylvania, United States of Amerien, 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:-
Our invention relates to braiding machines and more particularly to improvements
in the construction and arrangement of the bobbin carriers and the means for
guiding and operating them whereby great simplicity of construction and increased
efficiency in operation are secured.
The improvements relate especially to a braiding machine in which a single plate
is employed; and they consist mainly in the novel form of gear wheels employed
to drive the bobbin-carriers and the adaption of the co-operating parts thereto.
The invention is fully described in connection with the accompanying drawings.
Fig. 1 is a plan view of the bed plate of a machine embodying our improvements,
showing at one part thereof several complete gears with bobbin-carriers in position
thereen; at another part showing the upper disc of the gear wheels cut away;
and at still another part showing the carrier guide grooves uncovered.
Fig. 2 is an elevation of the same.
Figs. 3 and 4 are respectively a plan and sectional elevation on an enlarged scale
of two meshing gears and a carrier passing between the same.
Figs. 5 and 6 show the carrier in detail. Figs. 7 and 8 show a modified form
of the same.
Figs. 9 and 10 are respectively a plan view and sectional elevation in the main
similar to Figs. 1 and 2 but showing a modified arrangement.
Fige. 11, 12, 13, 14, and 15 are partial views illustrating on an enlarged scale
the construction indicated in Figs. 1 and 2.
Referring more particularly to Figs. 1 to 8 inclusive, A represents the bed plate
in which are formed grooves a a for guiding the bobbin carriers, said grooves being
shown arranged in intersecting wave lines as usual, curving around a series of
equally spaced posts or stud-bolts C. Upon these posts are mounted my improved
carrier-driving gears D D the whole series of which mesh together and derive
their motion from a single driving shaft as wo or y.
Each of these carrier-driving gears comprise two toothed concentric sections
or disks d and d', one of which is located above the other with an intervening space
into which the carrier extends as will be described later. The lower of these
disks, d, as shown, has a portion of its toothed periphery cut away at intervals to
form recesses d' so arranged as to engage the bobbin carriers E and swing the
latter in the curved path a. In forming these recesses however it is necessary to
cut away the teeth of the disk d in a manner which interferes with the proper
meshing of the gears one with another. In our mechanism. the upper disk dis
provided to supplement the main disk d and is preferably formed of a series of
arms or spokes as shown, equal in number to the recesses d and located directly
above the latter with one or more teeth d on the end of each arm or spoke adapted
to replace those cut away in the disk d and insure the regular and smooth working
of the gears. The spaces between the spokes or arms of the disk d' provide
clearance for the bobbin carriers E, which are of special construction to adapt
them for use in connection with the novel form of drive gears.
In Figures 5 and 6 are shown in detail these carriers E, which are also indicated

page_text: This
in position in Figures 1, 2, 3, and 4. The guide tongue or runner el travels in
the grooves a of the bed plate, and the flange laps beyond the groove in contact
with the horizontal face of the gears so that the latter shall serve to maintain the
carrier in erect position and insure a steady motion in its serpentine course.
motion is derived successively from the series of drive-gears d by the engagement
of the recesses in the latter with the stem or pin portion of the carrier in a
manner similar to that employed in ordinary braiding machines. The spacing or
pitch of the teeth may be as small as desired without affecting the perfect operation
of the machine inasmuch as whatever teeth are cut away or mutilated in the
portion of the gear are entirely replaced by the teeth d³ in the disk d¹. This
however requires that the carrier E shall be so formed as to properly support the
bobbin and tension weight above the gear without interference with the disk d',
and therefore a clearance space is provided between this carrier plate e on which
the bobbin and tension weight are mounted, and the steine, as indicated in Figure 6
or in the modified form of carrier shown in Figure 8.
A further difference appears between the carriers shown in Figures 6 and 8
respectively, which illustrates how the construction may bo varied without departing
from my invention. In Figure 6 the carrier flange e is arranged to lie between
the upper surface of the bed plate A. and the lower surface of the drive gear d, in
the manner most clearly shown in Figure 4. In the Figure 8 construction this
flange is arranged to lie between the upper and lower gear portions or disks d
and d as-shown in Figures 9 to 15. In this latter arrangement the bed plate A¹
is recessed in its upper face so as to lower the gears D until the upper surface d
of the lower disk d of the gear is level with the unrecessed surface of the
bed plate.
The flange e of the carriers then extends into the space between the upper and
lower disks d and d of the gear as stated, while the tongue e runs in guides or
grooves a below the gear recesses.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In a single plate braiding machine the combination with the grooved bed
plate of bobbin carriers guided therein and a series of carrier driving gears each
comprising a lower disk with teeth cut away at intervals to form recesses adapted
to engage and traverse the carriers and a superposed disk supplied with teeth at
the parts corresponding with, said recesses substantially as set forth.
2. In a single plate braiding mechanism as described the combination with the
grooved bed plate of bobbin carriers guided therein, and carrier driving gears, each
consisting of two toothed disks located one above the other with an intervening
space, one of said disks being recessed in its toothed periphery to engage and
transverse the carriers, and the other supplied with teeth to complete the gears
and recesses to permit the passage of the carriers between them substantially as
set forth.
3. In a single plate braiding mechanism as described the combination with the
grooved bed plate and the carrier driving gears, of bobbin carriers guided in the
grooves and driven by the gears, each of said carriers having a flange adapted to
contact with a side of a driving gear so as to maintain the carrier in erect position
and an opening in the carrier to permit its passage between the disks d' of adjacent
gears substantially as set forth.
