Claims. (Cl. 24255.1)

Thisinvention relates to certain new and useful improvements in lap sticks for a high speed picker and in particular reference to the textile arts.

It is well known to provide a lapstick which consists of a rod with a plate-shaped disk disposed transversely of the longitudinal axis of the rod at one end thereof with the disk being of relatively large diameter with respect to the diameter of the rod.

For automatic control of the operation of the apparatus, it is necessary that the lap stick rods be stored for quick change or insertion and the storing of such lap stick rods was extremely diflicult as the disk fixed to the rods prevented close association of the rods for the occupation of a minimum of space, resulting in relatively large or Wide spaces between lap stick rods.

To overcome the foregoing disadvantages of lap stick rods, the lap stick rod of this invention is formed in such a manner that the transversely extending part or element provided on the lap stick rod has radially extending fingers instead of a disk member with the fingers spaced from one another at an angle of less than 180 and the transversely extending element is formed of at least three fingers that extend from the periphery of the lap stick rod in radial direction. By the foregoing formation of a lap stick rod there is obtained the close association of the stick rods when stored together, there always being a free space between the fingers of the transverse element which makes it possible that the rods of adjacent lap sticks may lie very closely to one another. The arrangement of at least three fingers at the same angular distance from one another has the advantage that at least one finger finds a support at a backing member. Also, the design according to the invention enables storing of the lap sticks in the smallest possible space.

With the a-bove and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel for-m, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings, and claimed.

FIGS. 8 and 9 show the use of the lap stick according to the invention in a lap produced on a high speed picker.

FIG. 8 shows the cooperation of the lap stick with a hub tube upon which the produced lap is coiled.

FIG. 9 is a perspective front view of a high speed picker with the magazine for storing of the lap sticks according to the invention.

In the form of invention illustrated in FIGS. 1 and 2,

the reference numeral 1 designates a lap stick rod with a transverse element designated in general by the reference character 2 at the rear end of the rod and the transverse element comprises fingers 3 and 4 extending through transverse openings in fairly close relationship in the rod 1, and these openings are so arranged that the fingers 3 and 4 that extend from the periphery of the rod 1 have the fingers of each set displaced from one another for approximately In the form of invention shown in FIGS. 3 and 4, the lap stick 6 has a reduced neck 6 at the rear-end thereof for the mounting of the hub portion 6 of the transverse element designated in general by the reference character 7. This transverse element 7 is anchored in position by the swaged end 6 on the reduced end 6 of the rod 6 outwardly of the transverse element as illustrated. This transverse element is shaped like a cross with four fingers 7 and may be formed from a disk with cutout segments to produce the fingers 7*.

As illustrated in FIG. 5, the transverse element on the lap stick rod has three fingers 9 equidistantly spaced so that regardless of the rotative position of the rod one of the fingers will always be positioned between a pair of backing members 10, 10 (FIG. 6). As illustrated, the fingers are arranged with the same angular distance from one another and at an angle less than As illustrated in FIGS. 6 and 7, the lap stick rods may be stored in a comparatively small space for delivery to proper operating conditions. Upon storing, the ends of the rods 6 as well as the ends of the rods 1 provided with the transverse elements at the rear ends of the rods, lie in close relationship to one another and the rods are illustrated as extending through a slot 18 defined by the backing member 10 that is for-med of two parts for the support thereof. The right-hand ends of the lap stick 6 as viewed in FIGS. 6 and 9 are similarly supported, while both the right and left ends of the lap sticks 6 as viewed in FIG. 9 are supported in a conventional manner upon support elements 19, one of which support elements is illustrated and both support elements 19 can be moved to allow the lower lap stick to drop.

The lap stick is mainly used in connection with a beater machine, especially a high speed picker constructed by the firm Hergeth KG., Diil-men, Westphalia, In this Hergeth picker, a layer of fibers is coiled into a lap 11 on a hub tube 12. The tube 12 is provided at one end with a handle 13 and a collar 14. The lap stick 1 is inserted into the open side of tmbe 12. During the growth of lap 11 which may consist of natural or synthetic fibers, as for example cotton or artificial cotton, the hub composed of parts 12 and 1 is guided along vertical guidances. After completion of lap 11, the same is rolled by lap rollers 16 on a lap pan 17 which may be displaced in transverse direction of the machine. During this movement, the lap resting on the displaceab le lap pan is removed from tube 12, the collar 14 of which engages with a vertical guidance and is retained thereby. The lap stick remains into the lap.

Thereupon, the lap may be seized by means of the lap stick and may be carried to any desired place. The lap stick I removed from the lap may be inserted by hand at the upper end of magazine 15. By the special design of the rear end of the lap sticks, the same may be stored a) in close relationship to one another as is clearly shown in FIGS. 6, 7 and 9. Upon return movement of lap pan 17, the lowermost laip stick is extracted from the mag-azin'e and is inserted into hub tube 12.

While there are herein shown and described the preferred embodiments of the invention, it is to be understood that minor changes may be made therein, such as will fall Within the scope of the invention as claimed.
