BENJAMIN FARNHAM SMITH, 01" CONCORD, MASSACHUSETTS,

TWIS'IER RING.

To all w/zom 'a'z .uwy concern:

Be it known that I, 11L110 A. Kosnnn, a citizen of the Republic of Finland, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Twister Rings, of which the following is a specification.

This invention relates to twister rings of that type wherein the ring travelers are of substantial weight and are mounted in roller bcarings in series on a rail.

One of the objects of this invention is to provide a construction where as large traveler rings may be employed may have running clearance between each other. Cops or bobbins wound to comparatively large size so that replenishment is less often necessary may then be used in connection with the twisting mechanism.

A. further feature of the invention relates to the manner of supporting each traveler on four rollers, the number of bearings de creasing the wear over a construction wherein fewer are employed. By utilizing all the rollers possible to support two traveler rings, each of the traveler rings may have a four roller support and yet the whole series employs only two more than twice the number of travelers.

A. further feature relates to lubrication of the various traveler rings, any excess oil draining into a trough at one side of the rail where it may be readily removed.

Another feature of the invention relates to means for preventing the yarns from adjacent bobbins from becoming entangled due to the close spacing of the travelers.

Yet another feature resides in a construction wherein the roller-carrying brackets are integral with the rail.

Further features and advantageous details and combinations of parts will appear from a description of certain embodiments thereof shown in the accompanying drawingsin which- Figure 1 is a fragmentary plan of a rail showing 'a plurality of traveler rings in position thereon.

Figure 5 is a section on line 5 ure 1. i

Figure 5 is a fragmentary plan showing a modification.

Figure 7 is a section on line 7--7 of Figure 6. Referring first to the construction shown in Figures 1, 2, 3, and 5, 1 indicates the rail for supporting the ring travelers. As shown this rail comprises a casting having a series of perforated bosses spaced therealong as shown at 2 above which are positioned the ring travelers as will be described. Between adjacent pairs of bosses 2 and closer to the side edges of the rail, are other bosses 3 which are centrally perforated as at i for a purpose which will later appear. At one end of the rail is shown a pair of bosses 5 to which are adapted to be made fast brackets or casings 6, as shown in Figure l, which house small end bearing rollers 7 which, as will. be later described, help to support the end traveler rings of the series. At one edge of the rail is formed a trough shaped portion 10 and the upper surface of the rail between the various bosses slopes from the opposite side edge of the rail downwardly toward the trough 10 so that any oil which finds its way to the top surface of the rail is directed down to the trough where accumulations thereof may be removed by wiping the trough out as with cotton waste at intervals. The bosses 6 arranged adjacent the trough 10 are providedwith extensions 12 providing vertical walls 13 extending upwardly from the inner edge of the trough. The bosses 3 along the opposite side of the rail are extended to the edge thereof as shown at 14; which edge has a downwardly extending flange 15 thereon. Bracket mem bers 16 provided withdownturned ends 17 bridge across the width of the rail, the portions 17 engaging at one side outwardly of the flange 15 and at the other side against the surfaces 13 andbeingfixed thereto as by bolts. These brackets therefore bridge the rail at spaced pointsulengthwise thereof above the bosses 3 and between the bosses 2. The intermediate portions of the brackets 16 are spaced above the rail, and above the perforations 4; therein they are provided with perforated bosses 18 in which may be fixed journal pins or. shafts 19. These pins are somewhat smaller in diameter than the 5 of Figperforations in the bosses to permit of adjustment therein and are held in proper position by means of washers 20 and shoulders 20 overlapping the upper and lower ing into this space.

faces, respectively, of the bosses 18 and which are clamped thereagainst by means of nuts 21 threaded on the upper ends of the pivots. brackets are supported on the upper faces of flanged bearing rollers 25 which are journaled on the pins 19. As shown these bearing rollers each have depending bearing sockets 26 within which the pins 19 extend, these sockets 26 extending well into the perforation l of the rail bosses 3. At the periphery of each roller is formed a downwardly extending sleeve portion 250 concentric with and spaced from the outer face of the socket portion 26 this portion carrying upper and lower flanges 251. This permits a cup shaped member containing lubricant as at 27 to be held within each perforation t with its upper edge eXtend- As shown the cup 27 is provided with an outwardly extending bead 28 adjacent its upper end by which it is supported by the edge of the perfora tion 4. Lubricant in these cups is permitted to reach the bearing between the pins 19 and the sockets 26 through openings 2 laterally of these sockets.

Positioned between the flanges 251 of the rollers and supported for rotation thereby are the ring travelers shown at 30. It will be noted that these travelers, which are positioned between adjacent brackets 16, are supported entirely by the four rollers journaled therein while the end ring travelers of the series are supported by the rollers of the end brackets 16 and the rollers 7 positioned at the ends of the rails. The ring travelers are supported above the perforations through the bosses 2 and con centrically therewith, the perforations through these bosses, as shown, being of slightly less diameter than the central opening of the ring. Each ring, as shown. is

provided with a yarn eye 31 through which the yarn passes from the usual cop or bob bin (not shown) positioned below the rail in axial alinement with the ring travelers. As the strand passes up through the openmg and is rotated when the mechanism is in operation, it balloons outwardly due to the centrifugal force resulting from its rotation. As the adjacentrings are so close 'ogether since their outer peripheries almost touch, this effect if permitted would tend to cause interference between the strands acted upon by adjacent rings. For preventing any such action each bracket 16 is shown as having a fin 35 projecting upwardly therefrom between its pivot pins 19: these fins forming partitions or barriers to confine the strands from the travelers with- The washers 2O beneath the in proper limits to prevent encroaching on the paths of the strands of adjacent rings.

For the purpose of applying lubricant to the travelers as well as to provide a retarding action to their too free rotation, wiping pads may be employed. such pads being shown at 35 in Figures 1 and being preferably made of felt and each partially enclosed within a channel shaped head 3? carried at the end of a leaf spring 38. This leaf spring as shown is supported midway of its length on the reduced extremity of an adjustable pin 40 passing through one portion 1? of a bracket 16. A coil spring 4-1 surroumling a larger portion of the pin 40 bears at one end against a head 42 hereon, which is threaded into the bracket 16 and at its other end against one ace of the spring The head9 7 may have an opening 41-5 formed therein through which oil may be introduced into contact with the felt 36 so as to be transmitted thereby to the iieriphery of the ring traveler. this in turn being engaged by the rollers 25 in the adjacent bracket 16 transferring the oil to the nex adjacent ring traveler and so on through the entire set of travelers. As shown the wipers are arranged in pairs at either end of a spring 38 so that the need be supported only at each alternate bracket 16 throughout the length of the rail.

With this construction it is seen that each ring traveler is supported by four rollers, each. of the rollers carried by the bracket 16 serving to support two travelers, whereby the total number of rollers is two more than twice the number of ring travelers, these two additional being due to the end rollers 7 each of which engages only one traveler. As the brackets 16 bridge across the rail the ring travelers may be of sulliciently large diameter to pass under each bracket it being necessary only that the travelers should be sufficiently small to avoid actual contact in running. By employing such large travelers the winding size of the cop or bobbin may be large so that necessity of replenishment is rendered less frequent, thus saving time and labor in the operation of the machine. Any excess oil above that required to properly lubricate the travelers tinds its way down the inclined face of the rail to the trough 10 where it may be removed from time to time by running a piece of waste along the inner surface of the trough. By this means accumulation of oil which might soil the work is provided.

In Figure 4: a modification has been shown in which instead of forming the brackets 16 separate from the rail and fastening thereto as by means of the bolts shown, the brackets may be made integra with the rail. When this is done, in order llO tion.

to be able to properly assemble the parts, it is preferable to form the bosses 3' of the rail above which the rollers are mounted su'tiiciently large in diameter to permit the perforation l therethrough to be slightly greater in diameter than the diameter of the roller. The roller may then be inserted therethrough into position on the shaft 19 as shown in Figure 4L and the oil cup 27 may be formed with its lower portion o'l sufliciently large diameter to tit snugly within the hole l and its upper end reduced as shown at 27 to pass within the passage 27 of the roller. These oil cups may be held in position within the openings l by any suitable means such as leaf springs 50 made last to the lower face of the rail and engaging the lower faces of the cups. As the bosses 3" must be considerably larger than the bosses 3 shown in Figure 2, it may be necessary to cutaway a portion of these bosses or the bosses 2 to permit passageways for the oil down the inclined upper face of the rail.

In Figures 6 and 7 is shown a further modification, this modification residing in the construction of the end rollers and supports which act on the end rings only. In place of the rollers 7 shown in Figure l a pair otrollers 52 and 53 are shown which are journaled on stub axles 54: fixed to a bracket 5 upstanding from the face of the rail. These rollers 52 and 53 are spaced apart suflioiently to: permit the ring traveler 30 to pass therebetween and one of the rollers herein shown, as roller 53, is provided with an end. flange 56 to engage the outer vertical face of the ring. As shown the lower roller 53 may dip into a lubricantcontaining cup 57 supported on a portion of the rail so that lubricant may be picked up from the cup and transferred to the ring traveler. It will be noted that in this form of the device the rollers engaging the ring are journaled on horizontal axes while the ring traveler rotates about a vertical axis and that this construction permits the end rollers to be used to convey lubricant to the end traveler rings and thus tothe entire number of traveler rings.

Having thus described certain embodiments of this invention, it should be evident to those skilled in the art that many changes and modifications might be made therein without departing from its spirit or scope as defined by the appended claims.
