This invention relates to an improved method of driving the yarn supply carriers in a braiding machine and is especially adapted to the rotary or circular orbit type of machine where the yarn from one set of supplies is passed either inside or outside of the yarn packages of a second set of supplies as required to braid, and where both sets of supplies rotate in opposite directions about 9 a common center.
More specifically the invention discloses new and'improved means for passing yarn threads from one set of yarn supplies be tween a second set of yarn supply carriers moving in the opposite direction and the'driving means for said second set, by the use of a rotary-motion and discs having interrupted sectors and continuous sections substantially semi-circular in shape and adapted to'secure 1 interrupted contactwith slots on said carriers and to maintain a continuous push or pull betweenthe drivingmeans and each of said carriers, and at the same time to allow ample clearance and time for passing the yarn between said driving means and carriers.
' There is also disclosed a simplified driving means for both sets of supplies.
The inventionas specifically shown is hereinafter described with reference to the ac- 3' companying drawings in which Fig. 1 is a sectioned elevation of one type of'drive.
Fig. 2 is a plan view of the carrier drive shown in Fig. 1. I
Figs. 3, i, 5, 6 show in detail various positions of the driving discs and the ample clearance and time allowed for passage of the thread.
Fig. 7
is a sectioned elevation of a simplif? fled drive for the discs- Fig. 8 is a plan view of Fig. 7
Figs. 9 and 10 show enlarged views of the driving disc and gear, shown in Figs. 7 and 8. Similar numerals refer to similar parts throughout the drawings, and the normal direction of rotation of the variouslmoving parts are indicated by arrows.
The machine as specifically disclosed in Fig. .1 has a base 1 having a suitably bushed hole '2 for a drive shaft -3- having a bevel pinion +,4OI1 its inner end.
This bevel pinion 4" meshes with a bevel gear -5 adapted to drive the outer, or as shown, the lower set'of yarn supplies -6 in one direction, and also meshes with a bevel gear 7 adapted to drive the inner, or as shown, the upper set of yarn supplies 8- in the opposite direction, both sets rotating about'a common center.
This center of the base 1 has an upwardly extending portion 9 suitable for holding a hollow centralpost 1() locked by nut -24.-.
In the specific construction disclosed in Figs. 1 to 6, the outer yarn supplies 6 are carried on the outer carrier 11 mounted to. rotate on bearings 20 and -21. This outer carrier has suitable upwardly extending bars 12 attached to a thin casing A ring-shaped casting 14- is attached to the upper part of the bars 12 and has suitable holding means for the driving bars 15 which are also secured to the inner carrier raceway -16, thus causing it to rotate as a unit with the outer carrier 11-.
These driving bars -15 are thin so as to pass between the inner carriers 38' and their driving means at the same time that the threads .34-, coming from the F 1 outer supplies 6 through the loops on the lever 39, are passed.
Also attached to'the ring-castingl4- is a suitable yarn guide -"17-', and a support spindle 18. The bevel gear 7- resting on a suitable bearing l9 has an upwardly extending sleeve'- 22,- preferably keyed to it by key bevel gears -30 each meshed with two for the upper end of the outer package bevel pinions 31, Fig. 2. These bevel pinions drive disc shafts 32 and -33.
Mounted on or a part of these disc shafts are discs AB on one shaft 32 and CD on shaft 33-. Each of these discs has a sector removed and each pair of discs is so located on its shaft that while the yarn fi34 and driving bars 1." are passing by the cleared sectors on discs B and D, the sides of the discs A and -C are in contact with the slots 35 of the inner carrier shoes 37 which slide around inside the run of the raceway -16 and drive the inner carriers 38 With this construction shafts 32 and -33 rotate in opposite directions and the discs are timed so that discs A and C are in slots 35- when discs -B and -D are clear, or discs B and D are in the slots when discs A and C are clear.
In Fi 3, 4, 5, 6, the points :z: and yo the discs will enter their respective slots at about the same instant and one disc of each pair is always driving an inner carner.
Assumin the braider has eight inner carriers then t e shafts 32 and 33- will be geared to make eight revolutions for each one revolution of the outer carrier l1 and gear 29.
Therefore since the distance from center line to center line of slots 35- and 36 in each inner carrier shoe 37 equals about one-sixteenth of the whole circumference onl one-half revolution of shaft 32 or 3- will be required to clear the yarn 34 as it passes each slot.
In the simplified drive shown in Figs. 7, 8, 9, 10, the sleeve 11 is rotated with the outer carrier and the sleeve 22 rotates the inner carriers in the opposite direction by suitable means located in the base 1, but not shown.
By this construction the sleeve 11 can be fastened directl to the inner carrier raceway 16 by the ey 40 and the driving bars 15- are eliminated;
The sleeve 22 carries a bearing 4land is attached to or part ofthe bracketcasting --25.
This bracket-casting 25 has on its outer periphery suitable supports -42-, Fig. 8 for a stationary shaft or stud 43,
Fi and 8.
fiitatably mounted on shafts 42 are the interrupted or semi-circular discs 44 and 45 preferably made from one piece with a sleeve of smaller diameter connecting them.
In place of the bevel gears shown in Figs. 1 and 2, spiral gear teeth 46 are cut on the outer periphery of the discs, the teeth on each pair being cut as though on a single cylinder.
ome of these gear teeth 46- on each pair of discs are always in mesh with a large spi= ral gear 47 which may be suitably fastened to and/or rotates with the sleeve -11 and raceway 16-.
The discs 44 and 45 make eight revolutions for one revolution of the spiral gear 47 if there are eight inner carriers, therefore timing is maintained as described for the construction shown in Figs. 1 to 6.
Obviously the essential feature of this drive can be obtained in various forms without departing from the scope of the invention.
Therefore,without limiting myself to the precise construction shown, what I desire to secure by Letters Patent is the following:
