YARN TRAVERSE DEVICE Filed Dec. 28, 1966 INVENTOR. WILLIAM E. CAMPBELL AGENT United States Patent 3,401,894 YARN TRAVERSE DEVICE William E. Campbell, Jr., Pensacola, Fla., assignor to Monsanto Company, St. Louis, Mo., a corporation of Delaware Filed Dec. 28, 1966, Ser. No. 605,457 2 Claims. (Cl. 24243) ABSTRACT OF THE DISCLOSURE A yarn traverse device having off-set guide members to protect yarns against lubricant sprays.
Background of the invention One type of conventional textile traverse device designed to shift a yarn rectilinearly back and forth across the face of a bobbin comprises a grooved cam roll adapted to be driven and an integrally formed yarn guide and cam follower member that is slidably positioned within the groove of the cam roll. The cam roll imparts movement and reversibility to the yarn guide while spaced guide bars support the yarn guide and keep the guide member on a linear path of travel. Generally, the cam roll is covered and the guide bars are attached to the cover so that the only exposure of the cam roll to the yarn positioned in the guide member which is being traversed is through a horizontal opening or slot defined between the guide bars. In operating the conventional type traverse device, lubricant used on the cam roll is often slung or sprayed through the horizontal opening, falls onto the yarn carried by the guide and thus contaminates the yarn. The present invention is designed to prevent soiling of yarns by cam roll lubricants and to contain the lubricants.
Summary of the invention According to the invention, the novel traverse device comprises a journaled, grooved cam roll adapted to be driven and enclosed within a housing. The housing has a longitudinal opening at one side thereof and has opposed space guide rails or bars mounted adjacent the longitudinal opening. The guide bars are off-set and overlapped relative to each other. A combination cam follower-yarn guide member is slidably supported on and between the guide bars and has a front yarn guide portion and a back cam follower portion that slidably engages with the cam groove of the cam roll. In operation, the guide bar arrangement described defines a curved or devious path from the exterior into the housing so that lubricant spilling or spraying from the cam roll is deflected back into the housing rather than being thrown on a yarn as in prior art devices.
Brief description of the drawing In the drawing:
FIGURE 1 is a perspective view of the novel traverse device, and
FIGURE 2 is a cross section view taken through 22 of FIG. 1.
Description of a preferred embodiment Referring to the drawing, FIGS. 1 and 2, the traverse device embodying the invention comprises a housing 1 defining a longitudinal opening 2 substantially along the length and at one side thereof. A cam roll 3 with a traverse cam groove 4 of conventional configuration for moving a follower reversibly back and forth is rotatably journaled at its ends within housing 1. Cam roll 3 is spaced from housing 1 and is adapted to be rotatably driven by a motor 5.
At the side of housing 1 having the longitudinal opening 2 extending in axial alignment with cam roll 3, there are a pair of spaced guide bars 6 and 7. One bar 6 is secured to the upper edge or lip and the other bar 7 is secured to the lower lip defining longitudinal opening 2 of housing 1. Guide bars 6 and 7 are spacingly mounted and extend into the frontal area defining opening 2 in overlapped and off-set relation. Preferably, bars 6 and 7 are also slanted or angled to deflect a lubricant back into the housing.
To guide and traverse a yarn back and forth along a linear horizontal path, a combination yarn guide and cam follower member 8 of integral construction is provided. Member 8 has a yarn guide portion 9 with a yarn slot 10 for positioning a yarn therein at its front side (left of guide bars 6 and 7 as shown in FIG. 2) and a cam follower portion 11 at its back side (right of guide bars 6 and 7 as shown in FIG. 2), the latter being positioned within cam groove 4 of roll 3 and having slidable contact therewith. Intermediate yarn guide and follower portions 9 and 11, guide member 8 is slidably supported at its top and bottom sides by guide bars 6 and 7, respectively. Guide bars 6 and 7 engage within off-set complementary grooves formed in guide member 8.
In operation, a yarn 12 is positioned within guide slot 10 of follower member 8- and cam roll 3 is then driven in a counterclockwise direction (FIG. 2) by motor 5. It will be understood that prior to start-up, carn groove 4 of roll 3 will be lubricated. As guide member 8 is propelled reversibly back and forth by cam roll 3, centrifugal force will tend to cause lubricant to be thrown off of cam roll 3. Ordinarily, on conventional apparatus, lubricant would be sprayed through the longitudinal opening 2 between guide bars 6 and 7. In the traverse device disclosed herein, guide bars 6 and 7 provide a curved path or passage leading from the outside to the inside of housing 1 and act as a dam to deflect lubricant back into the housing 1.
It will be understood that variations from and modifica tions of the illustrated embodiment of the invention are expected to be covered within the spirit thereof and the scope of the following claims. For example, more than two off-set, spaced and overlapped guide bars may be used and the guide bars may be used without the casing.
I claim:
1. A traverse device comprising;
a journaled cam roll having a cam groove,
a casing spacingly covering said journaled cam roll and having a longitudinal opening therein axially aligned with said cam roll,
off-set, spaced and overlapped guide bars on said casing adjacent said longitudinal opening forming a curved passage from said casing, and
a slotted yarn guide slidably supported at opposed sides thereof on said guide bars and having slidable engagement with said cam groove for reversibly reciprocating said yarn guide.
2. A traverse device as in claim 1, wherein said casing has journaling means at opposite ends thereof and said cam roll is journaled within said journaling means.
