ROVING MECHANISM.

SPECIFIGATION forming part of Letters Patent No. 744,306, dated November 17, 1903.

To all whom it may concern:

Beit known that I, NAROISSE N. S. DAUDE-.

pose; but the flaring shape of the trumpet re-.

sults in accumulating and compressing the fiber and foreign matter in the concavity adjacent the trumpet-passage, whereby the latter opening becomes so restricted that the -rove is either attenuated or completely broken.

The above disadvantage is obviated by the novel auxiliary mechanism hereinafter described, and illustrated in the accompanying drawings, wherein like reference-numerals indicate like parts throughout the views.

Figure 1 is a front elevation of a section of a spinning-frame minus all the drawing-rollers except a part of the back lowerroller embodying myinvention; Fig. 2, a similar view of the same, showing the parts'in a different position; Fig. 3, a transverse section of a portion of the frame, taken on line .70 a: of Fig. 1, omitting the stop mechanism;Fig'. 4, a silni-' lar sectionof the same, including the stopv mechanism, but omitting the gearing; Fig. 5, a plan View of the roving-bar-actuating Fig. 6, a similar broken view of the bars and rollers, and Fig. 7 a detail perspective'view of one of the novel ring-couplets. I

In the drawings, 1 is the beam of a spinning or twisting frame 2, provided with the thread-board 3 and guide eyes or wires '4. The roller-stands 5 5 carry the usual drawing-rollers 6 7 and cap-bar 8, in the rear of which, mounted upon the creel or the frame, is the roving-bobbin 9, bearing the roving 10.

The lower back roller 7 carries upon its extremity a driving-pinion 11, which meshes with a gear 12, mounted on a stud 13, carried Heretofore certain funnel-1 other. 7 provided with a longitudinal slot 34 and the in a bracket 14, which is fastened to a support- 15. On the inner end of stud13 is gear 16, which meshes with gear 17'on stud 18,

T mounted in bearings 19, fastened to brackets 20 on support 15. Also secured to stud 18 is a cam 21, provided with an irregular circumferential slot or channel 22. Pivoted upon support 15 by means of pin 23 is a lever 24, provided at its end with a downwardly-projecting roller 25, which registers with the channel 22. To the end of lever 24tis pivoted an arm 26, fixed to an extension-piece 27, vwhich in turn is secured to the rear rovingbar 28. It will be noted that in my structure the roving-bar is in two parts 28 29, or rather comprises two contiguous bars. A pin 30 projects from the end of the'arm 26, to which is fixed the end of a retractile spring 31, whose opposite endis fixed to a pin in the rollerstand 5. Another retractile spring is secured atone end to extension-piece 27 and at its opposite end to a pin 50, projecting downward from the forward roving-bar 29.

The roving-bars 28 29 are slidably mounted in the roller-stands 5, which rise at intervals upon the beam 1. Upon the rear bar 23 rise at intervals the flaring rings 51. In transverse alinement with these rings, but upon the outer roving-bar 29, rise semicircular flanged rings 33, whose smallest radii are -much less than the minimum radii of the rings 51.' Each of the above ring pairs is traversed by a roving 10. The spring 32 has a tendency to slide one roving-bar past the To preclude this result, the bar 28 is bar 29 with a pin 35, registering with the slot,

thus limiting the sliding movement. mechanism with bar and rollers removed;

A downwardly-projecting plate 36 is fixed to the bar 29, adapted to strike against the upturned end of a lever 37, fulcrumed at 38 The end of this lever is depressed by a weight 4.0 and is limited against excessive depression by vertical post 41, fixed to the frame 2.

The operation of the parts involved in this invention is as follows: The series of rovings 10 pass from their bobbins 9 to the drawingrollers 6 7 through their respective guidingring couplets 51 33, arranged in series. The roller-pinion 11 drives the gear.17 through the intermediate gears 12 and 16, thereby rein a standard 39, mounted upon the beam 1.

volving the channeled cam 21, which longitudinally reciprocates the bar 26. Both bars 28 and 29 advance together, as shown in Fig. 1, until the projecting plate 36 on bar 29 contacts with the upturned end of lever 37 and temporarily interrupts its advance. Thus the rear rings 51 come out of alinement with the front rings 33, and the rovings 10 are drawn clear of the latter, Figs. 2 and 6, the rear bar 28 progressing independently of the front bar until the end of slot 34 of the former contacts with the pin 35 of the latter, whereupon the plate 36 trips and passes over the lever 37, and the tension of spring 32 instantly forces the bar 29 forward, and its rings are thereby instant-1y brought into alinement wit-h and accompany the rings 51 to the end of the travel of the roving-bars. The return of the roving-bars toward the right is effected by means of the rotating cam 21, both ring series being in alinement throughout the return traverse. The result of the ring interaction during the reciprocation of the roving-bars is to intermittently engage and disengage the semicircular rings with the roving, thereby preventing the accumulation of lint in the restricted orifices of the semicircular rings and without deranging the regularity of the reciprocating feed through the relatively stationary annular rings.

The function of the spring 31 is to retain the roller 25 against the wall of the diagonally-disposed circumferential channel 22. This overcomes the possibility of a momentary dwell of the said roller upon each halfrevolution of the cam 21. By this means is avoided the creation of circular ridges upon the drawing-rollers 6, due to a more prolonged contact with the roving at one point of the roller-surface than at another.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a roving mechanism, the combination with a roving-bar of annular guides thereon, a second bar adjacent the first, semi-annular guides upon the second bar in alinement with the annular guides, and means for intermittently forcing the semi-annular guides out of alinement.

2. In a roving mechanism, the combination with a roving-bar of annular flaring guides thereon, a second bar adjacent the first, semiannular flaring guides upon the second bar in alinement with the annular guides, and means for intermittently forcing the semi-annular guides out of alinement.

3. Ina roving mechanism, the combination with a roving-bar of guides thereon, a second bar adjacent the first, guides upon the second bar and means upon the'bars for normally retaining the guides in alinement with each other.

4. In a roving mechanism, the combination with a roving-barof guides thereon, a second bar adjacent the first, guides upon the second bar, means upon the bars for normally retaining the guides in alinement with each other and means contacting with one of the bars to force the two sets of guides out of alinement with each other.

5. In a roving mechanism, the combination with a roving-bar of guides thereon, a second bar contiguous with the first, guides upon the second bar and retractile means upon the bars for normally retaining the guides in alinement with each other.

6. In a roving mechanism, the combination with a roving-bar of guides thereon, a second bar adjacent the first, guides upon the second bar, means for normally retaining the guides in alinement with each other, means upon the second bar for contacting with a lever, a lever mounted adjacent the second bar, and in the line of travel of the contacting means thereof to force the two sets of guides out of alinement with each other, and means for reciprocating the bars.

7. In a roving mechanism, the combination with a spinning-frame of supports upon the frame, two roving-bars slidably mounted in the supports, guides at corresponding intervals upon both bars, means for normally retaining the guides in transverse alinement with each other, means upon one of the bars for contacting with a lever, a lever-support mounted upon the spinning-frame, a gravitylever pivoted to the lever-support, and in the path of the lever-contacting means to force the two sets of guides out of alinement, and means for reciprocating the roving-bars.

8. In a roving mechanism, the combination with a standard of a lever pivoted thereto, a roller mounted upon the free end of the lever, a cam also mounted upon the standard and provided with a diagonally-disposed annular channel in which the roller travels, an arm pivoted to the free end of the lover, a rovingbar connected to the end of the arm, and retractile means upon the bar for forcing the roller into close engagement with one side of the annular channel.

In testimony whereof I have aifixed my signature in presence of two witnesses.
