ROVlNG-GUIDE TRAVERSE-MOTION.

SPECIFICATION forming part of Letters Patent No. 727,191, dated May 5, 1903.

Application filed July 28, 1902. Serial nt.117,224. No model To all whom it may concern: 7

Be it known that I, LOGANOWEN, a citizen of the United States, residing at Macon, in the State of Georgia, have invented oertainnew and useful Improvements in RoVin'g Guide Traverse-Motions for Spinning-Machines, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The invention to be hereinafter described relates to rovinguides to beapplied to slubhers, Speeders, fly-frames, and in general to any spinning-frame in cotton or other textile mills Where the roving passes between the usual drawing-rolls prior to being spun; and more particularly the invention resides in the traverse-motion for the roving-guide, as will hereinafter appear.

It is a well-recognized fact that in the class of machines hereinbefore referred to unless there are provisions made for traversing the roving back and forth the length of the drawing-rolls the surface of said rolls, which is usually formed of leather or similar material, will become worn in grooves, so that the drawing action of the grooves under such conditions will become imperfect, resulting in an improper drawingof the roving and consequent irregular and improper character of yarn spun therefrom. Attempts have heretofore been made to provide the roving-guide; which is located back of the drawing-rolls, with a traverse-motion to continually vary the position of the roving as it passes between the rolls, and thereby prevent objectionable formation of grooves in the surface of said rolls; but in such prior devices special means have been provided, usually deriving motion from the rotation of the rolls themselves or from some other suitable source of'power, such means being generally disposed upon the roller-beam or top framing of the machine.

It is the object of my present invention to simplify the mechanism for giving a traversemotion to the roving-guides and cause its movement lengthwise of the drawing-rolls to harmonize with the bui1der-motion,-w-hereby the form of the cop or bobbin is determined; and to this end my invention consists, as generally stated, in means deriving its motion terfully described, and definitely pointed out in the claims.

In the drawings,Figure 1 represents in front elevation a detached portion of a spinningframe embodying my invention, parts being omitted in order to more clearly illustrate the mechanical construction devised bygne; and Fig. 2 is a cross-section of suchrnachine, showing also one of the bobbins or cops in the formation thereof. Y v i In the drawings, A represents part of the frame of the machine, and B the usual rollerbeam, above which and suitably supported in any convenient manner, notnecessary to herein illustrate, are the drawing-rollers C, by which the rovingD is drawn and reduced to proper size as it passes between said rolls to the spinning mechanism. I have not deemed it necessary to illustrate herein any particular form of spinning; device nor the particular character. of builder-motion employed, as either or both. of these. may be, of any usual or preferred form, and-as they form no part of my present invention,except in so far as the lifting-rail imparts motion to the roving-guide, will bewell understood by those skilled in the art withoutfurth'erillustration herein.

. Mounted in rear of the ;drawing roll o is the roving-guide E, mounted inany suitable form of bracketsE, supported from'any convenient portion of the machine-frarneas, for instance, from the roller-beamrzB. One of these supporting-brackets E, Ifhave illustrated in Fig. l, and; there maybe any number of such brackets, as will be obvious, ac cording to the length of the machine and the size or character of roving-guide. Ihe rovingguide, which may be of any approvedftype, is movable lengthwisein the'brackets E and is provided, as shown in the present'embodiment of my invention, with a series of guideopenings 6, through which the roving D is passed on its way to the drawing-rolls C. It will of course be apparent that other forms of guides for the roving D may be carried by the roving-guide E, and my invention is not limited in this respect.

Mounted, preferably, upon the roller-beam B is a bracket 5, upon which is pivoted at b a bell-crank lever F, having a slotted end f to engage a projecting pin f upon the rovingguide E, whereby as the bell-crank is moved upon its pivot b a proper traverse-motion longitudinally of the roving-guide may be imparted to the latter, the slotted opening f permitting the requisite play of the pin f for this purpose. The other arm of the bellcrank lever has an elongated opening f which is engaged by a pin f carried by a collarf on the actuating-rod G, and the position of the pin f in the slot f may-be adjusted to regulate the throw of the rovingguide E.

Secured to the machine-frame at any convenient position is the bracket H, having pivoted thereto by means of the pin h aconnector H, one end of said connector H having a slot h by which it is adjustably connected to the actuator G through the pin and nut h and whereby also the throw of the actuator G may be adjusted to vary the traverse of the roving-guide E. The opposite end of the connector H is provided with a slot 72 which engages a pin h secured to a part of the builder-motion, such part in the present embodiment of my invention being shown as a lifting-rail K, which derives its rising-andfalling movement through any suitable form of mechanism used for giving the traverse to the yarn upon the cop or bobbin, and such mechanism being well understood by those skilled in the art and forming no part of my present invention need not be herein further illustrated.

From the construction thus far described it will be obvious that as the lifting-rail K rises and falls under the actuating movement of the builder mechanism motion will be imparted to the connector H about its pivot h, as shown by dotted lines in Fig. 1, whereby the actuator Gwill be given a rising-andfalling movement andthrough the bell-crank lever F impart to the roving-guide E its traverse-motion to and fro approximately the length of the drawing-rolls 0.

It is sometimes desirable to change the traverse of the roving-guide to vary the position of the yarn between the drawing-rolls, and to accomplish this result I have connected the bell-crank lever F and the connector H to the actuator G by the pin-and-slot connections, as hereinbefore described, so that adjustment of either or both of these will serve to impart to the roving-guide E a traverse of greater or less extent.

While I have shown the connector H as a lever and have in the present embodiment of my invention disclosed it as operatively connected with a lifting-rail K of the buildermotion, it is to be understood, of course, that the form and character of this connector may be varied and that I may operatively engage it with any desired part of the builder-motion without departing from the spirit of my invention, and it will likewise be apparent that the actuator G may be operatively connected to the roving-guide by other means, it only being necessary that the rectilinear motion of the actuator shall be imparted to the roving-guide to carry the roving back and forth substantially the length of the drawingrolls.

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

1. A roving-guide traverse-motion comprising a roving-guide through which the material is delivered to the drawing-rolls, an actuator therefor, a builder-motion, and means connecting the builder-motion to the actuator.

2. Aroving-guidetraverse-motion comprising a roving-guide through which the material is'delivered to the drawing-rolls, an actuator therefor, operatively-connecting means disposed between the actuator and the rovingguide, a builder-motion and means operatively connecting the builder-motion with the a lifting-rail of the builder-motion, and a lever connecting said lifting-rail and actuator.

5. In a machine of the class described, the combination of a roving-guide through which the material is delivered to the drawing-rolls and a builder-motion, and operatively-connecting means disposed between the buildermotion and roving-guide.

6. In a machine of the class described, the combination of aroving-guide through which the material is delivered'to the drawing-rolls, an actuator therefor, a bell-crank in operative engagement with the roving-guide and adjustably connected to the actuator, a lifting-rail and a connecting-lever operatively engaged with the lifting-rail and adj ustably connected to the actuator.

In testimony whereof I have hereunto affixed my signature this 24th day ofJuly, A. D. 1902.

LOGAN OW'EN.
