To aZl' whom 'it may concern:
C. STURDE- Machines, of which the following is a specification.
This invention has reference to improvements in double traverse mechanlsm .for textile machines and its ob ect 1s to provide a' means to prevent the strands in traveling apross t e roller and back dwelling at each side in he same place at the finish of each j'ourney; across the roller so that the tendency to cause excessive wear in these particular places is obviated thus doing away with the necessity of changing the worn rollers to perfect rollers-to avoid bad work.
.With the present invention the traverse motion as a whole follows a zig zag path so that-the terminal points of the mot-ion are constantly changing.
The present invention is particularly applicable for worsted spinning and is of markedly simple construction and is positive in action.
The invention will be best understood from a consideration of the following description taken in connection with the accompanying drawings forming a part of this specification, with the understanding however that the particular construction shown is susceptible of modification in various ways without departing from the salient features of the invention.
In the drawings :Figure 1 is a view partly in diagram and partly in section showlng the application of the invention. Fig. 2 is a plan view of the traverse motion mechanism. Fig. 3 isa section on the line A-B of Fig. 4. Fig. 4 is an elevation of the double traverse motionmechanism as viewed from the left hand side of Fig. 1. Fig. 5 is a view of a small portion of a drawing roll showing in dotted lines the path of the usual traverse motion. Fig. 6 is a diagram on an exaggeratedscale illustrating the effect ofthe traverse motion illustrated in Fig. 5. Fig. 7 is a view of a small portion of a drawing roll showing the path of the strand under the action of the double traverse motion of the present invention. Referring. to the drawings there 1s shown a back roller 1 in Fig. 1 mountedon a shaft 2, which shaft carries a worm 3 engaging a worm wheel 4 'on onev end ofa .shaft 5, the other end of which carries aheart cam 6 and also a worm 7 adjacent to the heart cam 6. There is provided amain traverse bar 8 carrying a suitable number of roving guides 9 which'direct the yarn to the rolls. The
bar 8 has secured thereto a short rail 10 by aset screw 11 traversing a slot 12 in the rail which latter is provided for convenience of I setting the double traverse mechanism in place. The rail 10 carries a stud 13 to which reference will hereinafterf'be made.
Mounted on the main traverse :bar 8 is. a box casting 14 having an opening 15 therein and this casting 14 carries at one side an arm 16 secured to the casting let bytamset screw 17. The freeend of the arm 16 is ,appropria-telybent and carries a stud'18 entering the groove in the heart cam wheel 6.
J ournaled in the casting or block 14 and extending through the opening 15 is a shaft 19 carrying within the opening 15 a cam sleeve 20 provided with a cam groove 21 receiving the pin 13 on the rail 10. Theshaft '19 extends over the worm 7 on the shaft 5 and there carries a worni wheel 22 in mesh with the worm 7, while the other end of the shaft is journaled in a bracket23 fast on the bar 8.
In Fig.5 there is shown a small-portion of the periphery of a roller 1 displayed and at 24 there is indicated schematically the path of'the yarn caused by the traverse mo tion inordinary use. At the finish of each journey across the roller thereis a slight dwelling of the yarn always at thesame distance from the circumferential center line of the periphery of the roller. The consequence of this is an excessive wear in these.
particular places as indicated in exaggerated form at 25 in Fig. 6, thus necessitating the changing of the roller to avoid had work.
In accordance with the present invention the total lateral travel of the yarnpis the same as in the traverses in general use. but the extent of each lateral movementof the traverse is less than in the traverses referred to, this being indicated in Fig. 7 which also illustrates the roller 1 in displayed condition, while the line of travel of'the yarn on the roller .is schematically indicated at 26. The lateral movement of the traverse may center line of the roller.
bethe same as before so far as the number of movements to the progress of the roller .is concerned, but there is also provided a slower lateral movement which may be timed with relation to the circumference of the roller so that the dwelling of the yarn at the end of the lateral ourneys constantly changes with reference to the peripheral There being no point of excessive wear, an even surface is insured on the roller at all times.
a Motion is imparted to the shaft 5 from the shaft 2 by way of the worm 3 and worm wheel 4 and rotary motion is imparted to the heart cam wheel 6 by this shaft 5. The
- heart wheel 6 imparts a reciprocatory movement to the block or casting 14-. by way of the stud 18 and arm 16 and this motion is in a turn imparted to the main traverse bar 8 by way of the rail 10 and stud 13 which latter engages in the cam groove'21' of the sleeve or enlargement 20 on the shaft 19, and this sleeve or enlargement 20 being housed in the opening 15 of the blocklt participates in the movementof the latter. So long as the shaft 19 is not rotating then the movement imparted to the traverse bar 8 will be agreeable to themovement imparted by the heart wheel 6 to the arm 16. A slow rotative movement ishowever imparted to the shaft 19 through the worm. wheel 7 and worm gear or pinion 22, the rotative movement of the shaft 19 being slow as compared to the reciprocatory movement of the arm 16 and block 14. The relation of the block 14 to the traverse bar 8 is constantly changing because of the cam slot 21 in the sleeve or enlargement 20 causing a relative movement the surface of the roller over which theyarn passes combined with a secondary traverse movement of, less frequency. By properly proportioning the parts recurrent points in wear of the roller.
the path of a yarn on a roller may be so infrequent as to have no effect upon the even It will be observed that the cam or eccentric groove 21 causes the second traverse=movement positively in both directions.
What is claimed is 1. In a machine of the classdescrlbed, a
slidable bar with guides thereon fa block bar, a shaftjournaled in the block and provided with a cam, an operative connection between the bar and cam, means for rotating the cam, and means for imparting reciprocatory movement to the block.
3. In a machine of the class described, a
guide carrying slidable bar, a stud rail ad- I justable on said bar and provided with a stud, a block on said bar, a cam in the block engaging the stud on the rail, a shaft carrying the cam, and means for rotating the shaft and for imparting reciprocatory movement to the block.
4. In a machine of the class described, a
slidable bar with guides thereon, a blockcarried by said bar, actuating means for I imparting reciprocatory movement to the block, connections between the block and bar, and means controlling the said connections for changing the relation of the block and bar at a slower speed than the speed of reciprocation of the block.
5. In a machine of the class described, a reciprocatory guide bar, a reciprocatory block thereon, operative connections between the block and bar, and means for actuating said connections to vary the reciprocatory movements of the bar during the reciprocations of the'block.
6. In a machine of the class described, a reciprocatory guide bar, a block slidably arranged on said bar, means for reciprocating said bar, a cam sleeve carried by said block, and means on the bar coacting with said cam sleeve for varying the reciprocatory movement ofthe bar during the recip rocations of the block. I
In testimony that I claim the foregoing as myown, I have hereto aflixed my signature in the presence of two witnesses.
