ROVlNG-GUIDE TRAVERSE-MOTION.

SPECIFICATION forming part of Letters Patent No. 770,440, dated September 20, 1904,

Application filed February 9, 1904. Serial No. 192,759. (No model.)

To a, whom it may concern:

Be it known that I, LOGAN OWEN, a citizen of the United States, residing at Macon, in the State of Georgia, have invented certain new and useful Improvements in Roving-Guide Traverse-Motions, of which the following is a full, clear, and exact description, reference being had 'to the accompanying drawings, forming a part of this specification.

In my prior patent, No. 7 27 ,191, dated May 5, 1903, I have described a device wherein the roving-guide is driven from the builder-mo tion by connections between the guide and lifting rail.

It is well known that in the various forms of slubbers, speeders, fly-frames, and the like the lift-shaft for the builder-motion is given a varying rotating motion first in one and then in the other direction. For instance, assuming that the maximum rotative movement is one revolution, said shaft then revolves in the opposite direction to very near the startingpoint or to a point approximately one-half the diameter of the roving from the starting-.

point. Then it moves in the first direction to its maximum travel less one-half the diameter of the roving, then back again to the startingpoint less one-half the diameter of the roving, continuing to decrease the travel at each upward and downward movement of the buildermotion until the minimum travel is reached, at which point the bobbin is full, forming the bevel on each end of the bobbin. When this process is completed, the builder-motion has again reached a point to give its maximum travel, the filled bobbin is doifed and an empty bobbin put in its place, and the process is repeated. In the present embodiment of my invention I have taken advantage of this varying rotative motion of the lift-shaft to impart to the roving-guide the varying motion desired to prevent undue wearing of the drawing-rolls and in the present instance have provided the roving-rod with two guide eyes close together, which lead between the same pair of drawingrolls, whereby under the varying movement of the roving-rod the paths of movement of the rovings will be caused to overlap or cross each other near the center of the rolls.

In the drawings, Figure 1 is an elevation of a detached portion of a spinning-frame embodying one form of my present invention, some of the parts being omitted to more clearly illustrate the mechanical construction,

which more particularly pertains to the inventhen in the other direction to properly lay the yarn upon the bottom, as will be understood. Mounted upon the frame A are the usual drawing-rolls C, back of which is arranged the roving guide-rod D, movable longitudinally in suitable bearings, as d. The roving guiderod D is preferably provided with two guideeyes d and d for each of the rolls O, whereby the eyes d and cl guide a plurality of rovings between upper and lower drawing-rolls. Secured to the lift-shaft B is a beveled pinion B, which engages a segmental rack E, mounted to oscillate on a pivot E, carried by a bracket E The part' carrying the segmental rack E may for convenience of identification be termed the rack-plate F, the end thereof opposite the rack E being connected to a rod f at l f the opposite end of said rod f having a pivotal connection at f 2 with a lever f The lever f 3 is mounted on a pivot pin or stud f of any usual form, carried by suitable. bracket-arms f depending from the main frame A. that the lever-arm f 3 may be adjusted, the ends of the bracket-arms f are slotted at f. Connected to the end of the lever-arm f opposite the pivotal connection f is a rod g, the upper end of which at g connects with one arm, 9 of a bell-crank lever, the other In order arm of which, 9 is provided with a slot g engaging the pin g on the roving guide-rod. The bell-crank lever having the arms g and g is pivotally mounted upon a stand 9 which has a slot g for adjustment of the bell-crank lever, as will be obvious.

From the construction described it will be noted thatas the lift-shaft B is rotated first in one and then in the other direction it will through the gearing connection of the pinion B and rack E impart to the roving guide-rod D a reciprocating movement, and the length of each reciprocation of the roving guide-rod will depend upon the degree of movement given to the lift-shaft B. The lift-shaft B has imparted to it by the usual builder mechanism varying degrees of rotation first in one and then the other direction, the maximum of such rotative movement, however, usually not exceeding one complete rotation of the lift-shaft, from which it will be obvious that the transverse movement of the roving guiderod D will also vary as the movements imparted to the shaft are varied. The movement thus imparted to the roving guide-rod D will cause the paths of the rovings to be carried past the center of the drawing-rolls at each reciprocation, so as to equalize the wear on each side of the center thereof.

It will be obvious, of course, that various adjustments may be made in the connections between the lift-shaft B and the'roving guiderod D, so as to change the path or degree of reciprocation given to the roving guide-rod as desired. Changes may also be made in the construction and the gearing connection between the lift-shaft and the roving guide-rod; but the essential characteristic of this feature of invention is in providing gearing connection of some character directly between the lift-shaft and the roving-rod to give reciprocal movement to the latter.

In Fig. 2 is illustrated a modified form of the device where the lift-shaft B is provided with a gear B secured thereon, said gear B meshing with the rack B and said rack having suitable guide-lugs Z) for directing its upward and downward movement under the reverse rotative action of the lift-shaft. Connected to one end of the rack B isa lever b, pivoted at b in the slotted bearing 6 of the bracket-arms b, the end of said, lever Z2 being connected at b with a rod 6, which at its opposite end engages a bell-crank lever g g similar to that already described. From this construction it will appear that as the liftshaft is rotated first in one and then in the opposite direction it will move the'rack B up and down and through the connections described give the desired reciprocating movement of varying extent to the roving guiderod D.

In Fig. 3 still another modified form of invention is shown wherein the lift-shaft B is provided with a worm H, secured thereto, the said worm engaging the end of the lever H,

pivoted at h to the bracket-arms h, the upper end of said lever H having a slot 7L directly engaging a stud h secured to the roving guide-rod D, whereby reciprocating movement is imparted to the roving guide-rod direct from the lift-shaft B as the same is rotated first in one and then in the other direction.

It will be noted that the rovingguide-rod in each of the forms of invention shown is given its traverse-motion through gearing connections from the lift-shaft and that the roving guide-rod contains a plurality of guideeyes for each pair of drawing-rolls, the reciprocal movement of the roving guide-rod being such that the paths of movement of the rovings will by reciprocation of said rod be caused to pass the center point of each pair of drawing-rolls, and while I have shown the particular embodiment of my invention in the forms hereinbefore described I wish it to be understood that I do not regard my invention as limited to the details of structure disclosed, which may be changed within wide limits, the essentials of the invention being gearing connection between the roving-rod and the liftshaft for reciprocating the former and carrying the paths of the rovings to opposite sides of the center of the drawing-rolls.

The lever and rod connections between the roving guide-rod and the gearingactuated by the lift-shaft B may be generally designated as an actuator and the form of such lever and rod connection or actuator may vary within wide limits, as will be obvious, without departing from the spirit of my invention.

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-rod through which the material is delivered to the drawing-rolls, an actuator therefor, a lift-shaft and means connecting the lift-shaft and the actuator.

2. A roving-guide traverse-motion comprising the roving guide-rod for delivering the material to the drawing-rolls, an actuator therefor, a lift-shaft and gearing connections bctween the lift-shaft and the actuator.

3. A roving-guide traverse-motion comprising a roving guide-rod provided with a plurality of eyes for each set of drawing-rolls, an actuator for said rod, a lift-shaft and gearing connections between the lift-shaft and actuator.
