To all whom it may concern."

Be it known that I, SIMON Y. \VARDWELL, a citizen of the United States. residing at Providence, in the county of Providence and State-of Rhode Island. have invented certain new and useful Improvements in Braiding-ltlachines, of whiclrthe following is a specification.

My invention is an improved braiding machine and comprises means for augmenting the braiding capacity, enhancing the quality of the braid, facilitating operation of and imparting durability to the machine, all of which are accomplished in the peculiar manner set forth in the accompanying specification and illustrated in the accompanying drawings, which show respectively: Figure 1, a sectional elevation of my improved machine; Fig. 2, an enlarged portion of Fig. 1 showing more clearly the relations of the parts; Fig. 3 is a view show ing the mode of operating the switches and I the latter open to admit the sinuat-ing yarns below the carriers; Fig. 4 is similar to Fig. 3, but shows the switches closed, to direct the siuuating yarns over the carriers, and also the arrangement of the drivers; Fig. 5 is a detail of the heater and heater cam; Fig. (3 is a .detail of the angle plateg'Fig. 7 is a view looking in the direction of the arrow D- Fig. 6, showing mode of mounting the angle plate and details of the foot pieces 59 and 60. i

The machine of my invention comprises a frame 2, an outer turret 3 rotatable-in one direction on the ball bearing 41 on the frame, and an inner turret 5, having a head 6, rotatable in a direction opposite to that of the outer turret on the ball bearing 7 on the frame. A gear 8 engaging both the inner turret and the outer turret, and driven by the pullev 9, serves to drive the two turrets,

in opposite directions as described. The devices for causing the pulley to operate or not operate the machine and for automatically arresting the pulley operation and the movement of parts propelled by the pulley are subject of another application and will not' way 10 in the ring 10 to permit play of the lower yarn m as it sinuates over and under the carriers-Figs. 6 and 7.

The carriers 1'4 are propelled by the inner turret 5, through drivers 16 of which there are two to each carrier. They are disposed in conico-radial slots or guide ways 17 of the conical rim 18 of the inner turret head 6, see Fig. 4. These slots are cut entirely through the said rim, so the drivers ride directly .over the conical inner surface 19 of the outer turret, but on the flange 18 of the rim 18, and on the wall 53 of the dished portion 53. The drivers are projected into and withdrawn from engagement with the carriers 14 by the cam groove 20 in the surface 19, through the rolls 21, of which there is one on each driver. On the deck of each carrier are two elevations 22 with each of which a driver engages. The arrangement of the drivers with respect to the cam groove 20 is such that each carrier is at all times engaged by one of its drivers and that each driver is withdrawn from the path of a passing yarn 00 so the latter may encounter no obstruction, in going beneath the carriers.

Braiding is effected by causing the-sinuating yarn in to pass over some carriers and under others, through the space 23 between the carrier and the ring 24. On the ring 24 are switches 25-25, etc, spaced to correspend with the leading points of the carrier decks.

lVhen the switch ring 2twith its switches 25 is in the position indicated by Fig. 3, each of the lower yarns or. traveling in the direction of the arrow B with respect toand over a carrier. will after passing that earrier go beneath and under the next through the passage 23. While the yarns :11 are so passing beneath the carrier, the switches are.

shifted into the position shown in Fig. 4, and the yarns .r ride in the direction of the arrow C, up over the next succeeding carriers. The means and manner of so shifting the switches are as follows: The ring 24 is frusto-conical in external form, correspond-- ing with the interior surface of the head 6 of the inner turret 5, and is 'naintained in its horizontal plane by the bearing brackets 26. Incidentally the ring 24;; rests over and helps to retain the drivers 16 inthe guide ways 17. Primarily, it carries the switches 252525 and moves them through their prescribed range of action, actuated through the lever 27 by the cam 29. The latter is secured to the frame 2 by screws vide for a proper timing of the switches with reference to the movement of the carriers. The cam is maintained central in the machine by its bore 35 which fits the cylindrical surface 36 of the central tubular standard 32.

The lever 27 is carried on a stud 37 mounted on' the inner turret, and engages" the'ring 24 by its extremity 38 which enters a corresponding recess 39. The ring 24 has therefore the same general rotative movement as the inner turret, with an independent oscillation caused by the cam 29 sufiicient to properly operate the switches.

After the yarns have been properly interlaced, they'draw together at the braiding point 40 where the braiding is compacted bya beater 41, so called. This is a sleeve ver-' tically slidable on the tube 42 set in the top of the tubular standard 32 through both of which the core of the braid is drawn. At the bottom of the beater is a spider 43 which is prevented. from turning by the pin 44 secured in the upper flange 45 of the central standard 32 and passing through an arm of the spider. The arms of the spider engage the rotatable cam 46 whereby the beater is caused to "ibrate, its nose 47 playing against the yarns near the braiding point 40 and compacting the fabric.

The beater cam'46 is secured to the honnet 48, which issupported on the spider 49,-

the hub 50 of which rides on the shoulder 51 of the central standard. Its top bore fits the top fian'ge 45 of the central standard engaging the lower half thereof, the upper half being surrounded and engaged by the 'cam 46 itself. Thus the cam 46 is centered directly by the central standard, ratherthan by an intermediary thereby eliminating a source of inaccuracy of alinement.

The beater 41 and cam 46 are covered by a conical cap 52 which shields them from dirt :and damage and, equally important, provides a polished bearing 53 over which the yarns draw to the braiding, preferably by a hardened. bushing set into the cap. The bonnet 48 protects the interior of the machine from dirt and other foreign sub-.

stances or articles. Protection from dirt is quite essential, because within the machine is an oilreservoir the contents of which must not be impaired inlubricating quality by the admixture of lint, fly and other extraneous matter.

It has been noted that the head 6 of theinner turret5 is dished. This dished portion 53 constitutes the oil reservoir, into which the drivers dip, carrying up oil so that it reaches the clearances between the drivers and the walls of their guide ways 17, and by capillary action feeds up these, thus conveying oil to the cam-rolls 21 and their groove 20. This arrangement further supplies sutiicient oil for'lubricating the carriers without excess. Capillary action causes oil to creep over metallic surfaces and this tendency augmented" by the centrifugal action due to high speed of rotation of the turret, and restricted by the inclination of the drivers and their guideways, conveys enough oil, without surplus to the carriers and to their race-way 13-.

. It is vitally essential that the yarns m, as they sinuate among the carriers. shall be fully controlled and'not susceptible to deflection by aircurrents, vibration of machine parts or of the machine itself due to insubstantial setting. To insure such control I employ, what I term, an angle guide 54 which is formed as a dove-tail at its mid-section, -where secured, to engage the dove-tail seat 54 in the ring 10, at the thread-way 10see Fig. 6. Referringto Fig. 6, the apex 55 of the angle groove 56 of the thread guide is below the path of travelof the point of the deck of the car- 'rier 14, and the guide eye 57 of the take-up arm 58 of the lower supply is so located that the yarn in when in its mean position, or,in other words, when drawn directly from the eye 57 toward the braiding point 40, passes below the line of travel of the'points of carrier decks and through the apex 55 of the angle guide. Further, the guide eye 57 is to one side of the straight line drawn from the braiding point 40 through the apex 55 of the angle guide, and in such direction that the yarn pulls into the apex so that it is under tension when it passes said guide and is therefore steadied against chatter and vibration and air currents. Thereby, it'holds the yarn when the latter is not purposely deflected, to that position where it shall invariably. and surely pass below the carriers through the. channel or space 23. The angle guide also constitutes an abutment to resist deflection of the yarn in the direction of carriers movement to secure prompt response in a vertical direction, and further, when the carrier does encounter the yarn, the upper inclined edge 66 of the angle guide coacts-with the carrier to elevate the yarn, while the lower edge 67 coacts therewith to depress it.

The angle guide is held positively from vertical displacement by shoulders 68' which engage the track, the guide yielding elastically to permit such insertion.

The carriers are held down by thesmall foot pieces 59 and 60 in the-carrier runner 61, which foot pieces engage the recess 62 of the carrier race 13. The foot piece 59 is permanently secured to the carrier by suitable means, such as a rivet and is of such length that it will enter the race 13 through the thread-way 10. After ithas thus been entered the other foot piece 60 is applied. The latter has a stem 63, the extremity of which is beveled and has below the bevel a notch 64. On the deck of the carrier is a spring which engages this notch, holding the foot piece 60 securely to its seat 64 in the carrier runner. This arrangement is peculiarly advantageous because it admits the use of a solid, integral ring 10, and avoids the difiiculties and inaccuracies incident to the employment of a sectional ring or a ring that on every other yarn, but will remain so because there are no interconnecting joints between the switches 25 and therefore there is not felt the effect of cumulative backlash invariably developed in articulated mechanisms. The self-lubricating system for the driver and carriers is novel, and vital on account of the high speed to be maintained. In other words, the possible speed of mechanical action can be sustained only by perfect lubrication of the moving parts. Too little lubrication will cause seizing and wear, with consequent degeneration of action, yarn breakage, resultant waste and general impairment, both of product quality and quantity. Too much lubrication would drench the machine and its yarn and ruin the product. By the peculiar disposition of the machine parts, with the drivers so disposed as to recurrently dip, into an oil supply, sufiicient oil is drawn up'to be distributed as above described, by capillary and centrifugal action, while the inclination of the drivers and of the surfaces with which they coact, o poses to these com-' bined actio ns an up-hi l resistance which supplies the necessary restricting effect to control the delivery of oil.

The bonnets 48 and 52 completely cover the internal mechanism, presenting surfaces readily cleaned and protecting the contained oil from fouling, and also the acting parts within.
