9 Claims.

This invention relates to a hier for roving or similar use; and has for one of its objects the provision of a ier which may be inexpensively formed and yet be eective and efficient in its operation.

Another object of the invention is 'the provisionl of a nier which is so constructed that it may be molded from plastic material such as Bakelite or the like.

Another object of the invention is the formation of a flier in which the various parts are balanced that relatively high speed operation may be had without detrimental vibration.

Another object of the invention is the leading" of the Work into the flier in such a manner as to protect the work against windage due to rapid rotation.

Another object of the invention is to construct the nier in such a manner that it may be easily and quickly threaded.

Another object of the invention is the arrangement of a presser foot through which the work is guided that the same may be moved against the yarn package by reason of centrifugal force.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

In thev drawing and winding of roving, it is desirable to protect the roving as much as possible from Windage and ballooning as it is packaged, which I accomplish by a cylindrical hier enclosing the work; and in order that such a iiier may be formed inexpensively and yet be balanced properly for high speed operation, I have arranged to mold the flier from Bakelite or some similar synthetic material which may be produced with the desired smooth finish and with portions thickened and recessed as desired for the vaccomplishment of different desired functions of the device;l and the following is a more. detailed-description of the present embodiment of this invention, illustrating the preferred meansbyvwhichI these advan-V tageous results may bev accomplished:

With reference to the drawing, II) designates generally a cylindrical flierV formed of Bakelite or someV similar synthetic-.material 'which may :be molded with asmooth outerv surface and Yinthe desired shape to form side walls Il andran end wall I2. A metal plate I3-is'm-oldedfinto the top wall I2 of the nier with its portions undercut so that the molded material may embrace thesame as at I4 to hold the plate firmly'embedded therein. An opening l5 is 4providedin .'the,.Bakelite portion ofY this topwall for the reception ofsa driving shaft I6 and its collar I8 which .is xed thereon with a portion of the shaftY I6 beyondthe collar extendingthrough a smaller opening I1 ini-20 the plateV I3 againstfwhich the'collar abuts asat I9 and is lockedto the-plate as at 20 lso `asto y positively cause-the: flier to turn Withtheshaft IB and its collar I8 xed thereto. .A nut 2l on the reduced threaded endof the. shaftllholds the hier firmly infposition onithe shaft.

A recess 22 is formed inthevouter surface of the end vvall'which registers with the work opening 23 in thev collar and. opening 24 in theshaft through whichthe. roving-261 passes -soas to be below the outer surface of: the endy wall and thus be protected against Windage'due torapid revolving of the flier. LA hole '25 at the juncture of the .side wall and end twallA andv registering with the recess 22 is formed. forrthe workwhich is indicated by the dot-dash line. 26 to pass therethrough into the interior of the flier. A slot=21 extending downwardly Vthrough the side wall of the flier from the recessiZZfis formed with its trailing edge inwardlyY beveledas atv 28, while its Ieadingedge V29 is substantiallyradial of the cylinder.

A cylindrical tube E30 is rotatably mounted in a recess in the-Wall II-with its upper end in an enlarged portion 3| of the opening'l 25 with the stock 32 of the cylinder enlarged by beingl swelled inwardly to receive and. provide a bearing for this upperfendoftheitube 30. `This stock is cut away in the 'formiofiaA Vasratf33 and a nger`-34is xedly'mountedon the upper end ofthe tube: 3D and may swingsbetween the surfaces of this notch 33 to limit thelrotative. -movementof the tube to substantially 390.

The lower end of the tube is providedwith'a bearing formed by-a metal plate-35 which has a `pair oflugs36`ttingfwithin recesses 31 on'the inner wall. of the tube and rotatably receiving in a recess 38 the lower end of the tube 30. This plate is held in position by screws 39 passing through the wall of the ier and entering threaded holes in the plate 35. A stop 40 is fixed to the tube and engages the upper edge of the plate 35 to hold the tube against sliding outwardly from cylinder, while a presser foot 4| has a boss 42 mounting it on the tube 30 with an end 43 having an opening 44 therein for receiving and guiding the roving 26 onto the bobbin 48 of the machine. The tube 38 is slotted as at 45 while the boss 42 is slotted as at 46, which slots register With the slot 21 of the cylindrical body when the presser foot is swung abnormally outwardly so that the yarn 26 may be drawn through the slots into the center 4l of the tube, after which the presser foot may be swung inwardly into close proximity to the bobbin 48, as winding occurs, which movement moves the slots out of registry and prevents the yarn or roving from escaping from the tube.

In order to force the presser foot inwardly against the bobbin a lever 50 is pivoted as at 5l to the plate I3 which is molded into the top wall and is provided with a suitable weight 52 thereon, while its end has a hook portion 53 which engages the finger 34 on the upper end of the tube 38. Thus, as rotation occurs the weight 52 being greater than the weight of the presser foot is caused by centrifugal force to swing outwardly with reference to the axis of rotation and force the presser foot inwardly against the bobbin.

The plate i3 is of an irregular shape with a.

portion 55 at one side of the axis to balance the centrifugally acting weight 52, while the cylindrical body itself is thickened as at 56 to balance the weight of the tube 38, and thus it will be apparent that the thickness of the Bakelite body is such as to provide the proper balance for the iiier that a high number of revolutions per minute may be had without vibration.

The device being made of Bakelite presents a very smooth iinish and surface over which the yarn may travel without abrasion and also without materially wearing the Bakelite due to the inherent lubricating properties of the same.

In order to drive this flier, suitable gears l are provided on the shaft I6 which are driven through gear 58 by gear' 59v on the shaft 60 which is driven in turn by the spiral gear 6| from some suitable source of power. The bobbin 48 is driven on spindle 62 also from some suitable source of power, the same being mounted upon the traversing rail 63, all as more fully described in my Vco-pending application, Serial No. 137,683, filed April 19, 1937.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being dened and limited only by the terms of the appended claims.
