R. H. CLINE METHOD OF FORMING ROLL Original Filed Oct. 21, 1954 June 6, 1961 INVENTOR. ROBERT CL/NE M ,6 a V A T TORNE Y United States Patent P 4 Claims. (Cl. 154-117) This invention relates to a method of forming a roll of absorbent material or the like on a cable, such roll and cable being particularly useful in an applicator for applying insecticide to animals, such as cattle, wherein the animal itself furnishes the relative movement between the applicator and the animal. This application is a division of my copending application Serial No. 463,686, filed October 21, 1954, and entitled Animal Insecticide Applicator, now U.S. Patent No. 2,835,225.

In my copending application Ser. No. 463,686, there is disclosed and claimed an insecticide applicator, in which a roll of absorbent material is mounted on a cable which is preferably mounted so as to extend at an angle to the ground, the absorbent material being enclosed within a jacket of relatively heavy woven material, which also extends over a reservoir adapted to contain an insecticide solution, disposed at the upper end of the roll and also rotatable about the cable. The applicator is engaged by an animal rubbing against the same, who receives the insecticide solution through the roll and the covering. While such a roll may be wound tightly about a cable, it normally tends to remain fixed in position on the cable after installation and an undue amount of wear is caused by animals rubbing against essentially the same spot on the jacket, thereby causing the jacket to wear out relatively quickly. Thus, it is highly desirable to provide a roll of absorbent material on a cable which may move relatively thereto during use.

Among the objects of the present invention are to provide a novel method of forming a roll of absorbent material on a cable to provide such a method which permits the roll to move relative to the cable after installation; to provide such a method in which the roll may be rolled about the cable as tightly as desired; and to provide such a method which is simple but effective in use.

Additional objects and the novel features of this invention will become apparent from the description which follows, taken in connection with accompanying drawing, in which:

FIG. 1 is a front elevation of an applicator in which a roll formed in accordance with this invention is particularly useful;

FIG. 2 is a longitudinal section of a roll and associated parts, forming a portion of the applicator;

FIG. 3 is an enlarged cross section taken along line 33 of FIG. 2;

FIG. 4 is a fragmentary enlarged view, taken at the end of a layer of absorbent material preparatory to rolling the same onto a wire rope or cable;

FIG. 5 is a fragmentary cross section showing the absorbent material rolled onto the cable;

FIG. 6 is a similar cross section showing theroll after release so that it may rotate about the cable or move longitudinally thereof; and

FIG. 7 is a fragmentary, enlarged longitudinal section of a solution reservoir and associated parts.

An applicator A, constructed in accordance with my application Serial No. 463,686, may be mounted for rotation on a wire rope or cable 10 which extends at an angle between an eye bolt 11 on an anchor 12 and through a pulley 13 attached to an eye bolt 14 mounted on a post 15, with a counterweight 16 attached to the free end of cable 10 to permit the cable 10 to be drawn partly through Patented June 6, 1961 the pulley 13 as a steer moves against the applicator A. The anchor 12 may be a relatively short post embedded in the ground 17 and the post 15 may also be embedded in the ground 17. As will be evident, the steer may move underneath the applicator A to permit the same to roll along his back and part of one side, although it will be understood that when the steer moves under the applicator from the opposite direction, the applicator will roll against part of its opposite side. Also, the steer may move forwardly against the applicator with its chest and also may step over the applicator to rub its belly and a portion of either side against the applicator. Of course, by

backing into the applicator, the steer may engage the same.

with his rear legs and buttocks, while its ears and neck may be readily engaged as well as its chest. The tendency for steers and other animals to rub against posts, fences and the like is well known, and this tendency is taken advantage of in placing the applicator at such an angle,

may include a mineral oil base and a suitable insecticide.

for ridding the animal of insects, such as lice, flies, ticks, grubs and the like. Insecticide suitable for addition to the mineral oil base include pipernyl butoxide and pyrethrins, as for dairy cattle, or DDT, DHC and rotenone for range cattle, or any other desired type of insecticide. The mineral oil may be a paraflin base oil of approximately 10 or 20 SAE.

The applicator A includes a self feeding reservoir R at the upper end, a clamp 18 being mounted on cable 10 above and below the applicator A to limit longitudinal movement thereof, if desired, although the principal longitudinal support for the applicator comprises a clamp 19 inside the same, as in FIG. 2. Clamps 18 and 19 may be cable clamps, or sleeve pressed onto the cable by several. tons pressure. The applicator also includes a wick roll 20 of matting, preferably cattle hair and jute, which appears to hold the oil better than other types of absorbent material.

In accordance with this invention, the roll 20 may be formed by taking a section of matting, such as three feet long and six feet wide, folding a layer of burlap 21 over the same, as in FIG. 4, and attaching a piece of adhesive tape 22 to one side of the burlap covered matting and to the cable 10. Tape 22 may be formed of plastic or other suitable material provided with a layer of adhesive on one side, masking tape being particularly suitable for the purpose. Preferably, one adhesive edge of the tape 22 engages one side of the burlap covered matting and the opposite adhesive edge of the tape engages the cable 10, which need not be completely surrounded, although the tape may be applied in any other suitable manner. When thus held by the adhesive tape, the matting is rolled, as in FIG. 5, onto the cable 10 to the desired dimension, as by turning the cable 10, and then secured at several points by binder twine. Then a jacket 23, preferably formed of relatively heavy woven cotton, as of the type normallyused as a fire hose covering, is slipped over the roll. Then, a reverse twist may be given to the cable10, so that the portion of the adhesive side of tape 22 formerly secured to the cable 10, will unwind from the cable and onto the burlap 21, thereby freeing the cable from the tape and permitting the roll to rotate about the cable, as well as move longitudinally thereof, particularly since the nonadhesive side of the tape provides a smooth surface against the cable. It will be noted that, with the adhesive side of the tape against the burlap, the tape will not tend to be dislodged irrespective of the direction of rotation of the roll relative to the cable. In addition, when the roll becomes saturated with the insecticide solution,

particularly when a mineral oil is utilized, the solution will also act as a lubricant to permit greater freedom of movement of the roll about the cable. It will be noted that the roll may turn or move relative to the cable, even though it is tightly wound onto the cable, and that such movement is of particular advantage during use, since the portion of the jacket 23 contacted by the animal will be continuously changed, thereby adding to the useful life of the jacket.

The jacket 23 is preferably longer than the length of the roll of matting 29 extending over the same at both ends, so that a wooden plug 24 may be slipped within the lower end of the jacket 23 and the reservoir R slipped within the upper end. Prior to the latter, a portion of the matting may be cut away at the upper end to receive the clamp 19. A metal strip 25 fastened by a clamp 26, such as of the Band-I type, may be utilized in clamping the jacket 23 securely to both the wooden plug. 24 and the reservoir R.

The reservoir R, as in FIG. 7, maycomprisea central pipe or tube 30, which extends centrally of and past each end of a cylindrical container 31, conveniently formed of light steel, such as l6-gauge, and is soldered, brazed, welded or otherwise suitably attached to the tube 30. In addition, a connection 32 for a filling plug 33 may be welded, brazed or otherwise suitably mounted in the side of container 31 adjacent the upper end thereof. Connection 32 conveniently comprises one-half of a small pipe union, the same nominal size as plug 33. The container 31 is filled by removing plug 33, pouring ahalf gallon or the like of the insecticide solution into the contaier, and then replacing plug 33.

After the plug 33 is replaced, the only exit for the solution from container 31 is through a small hole 34 in pipe 30, inside but adjacent the lower end of the container 31. The solution is discharged from the reservoir R only as it is used up, by being agitated throughuse. This is due to the fact that the oil base. insecticide does not tend to flow readily through hole. 34, since a vacuum is produced in container 31 and is not broken at hole 34 until .the container is agitated. suficiently to cause one or more air bubbles to move from hole 34 to the top of the container through the solution. Thus, when the. tube 31) is agitated, drops of the insecticide solution will be discharged through hole 34, and will move down along the cable to saturate the matting 2i From the foregoing, it will. be evident that the. method of forming a roll of absorbent material on a cable, in accordance with this invention, fulfills to a marked degree the requirements and objects hereinbefore set forth. As Will be evident, the use of adhesive tape, such as masking tape, in initially attaching the end of the layer of absorbent material to the cable, for rolling the same thereon, is inexpensive, and very simple to use. Also, the edge of the absorbent material is held to the cable while being rolled thereon, so that the roll may be made as tight as desired. A reverse twist of the cable, after the roll has been made and secured, is a relatively simple expedient, but produces extremely valuable results. Thus, not only is the roll free to move relative to the cable, both rotationally and longitudinally, but the reverse twist of the cable causes the adhesive side of the tape to adhere to the inside of the roll of absorbent material, while the non-adhesive side of the tape provides a smooth surface for movement along and about the cable.

While this invention has been described with particularity in connection with the forming ota roll for use in an animal insecticide applicator, it will be understood that the method may beutilized in forming other types of rolls which are to be wound. relatively tightly about a cable but relative movement between the roll and the cable is desired. It will also be understood that the terms cable and absorbent material, as used in the appended claims, are not limited strictly to what might be called, from a commercial standpoint, a cable or absorbent material, respectively, but encompass the equivalents thereof, particularly any element which might be substituted for a cable to form a center for rotation for the roll, whether flexible or non-flexible, and any material adapted to form a roll. It will also be understood that variations in the steps of the method of this invention may be employed, all without departing from the spirit and scope thereof.
