No. 288,558 Claims priority, application Japan, June 18, 1962, 37/32,709; Aug. 6, 1962, 37/44,461 3 Claims. (Cl. 15-25652) This invention relates to lint clearersfor use on spinning machines and intended to provide an improved lint clearer, which dispenses with any spring, metal fixture or other mounting device as required previously and thus can conveniently be mounted in a narrow space and is readily removable.
In order to attain the above objective, the lint clearer of the present invention is comprised of a tubular body, a magnet housed in said tubular body, and pole pieces formed of ferromagnetic material and held in contact with the two poles of said magnet.
According to another aspect of the present invention, the lint clearer comprises a tubular body formed of nonmagnetic material, a magnet housed in said tubular body, and pole pieces formed of ferromagnetic material and housed in said tubular body in contacting relation with the two poles of said magnet.
According to a further aspect of the present invention, the lint clearer comprises a tubular body partly formed of nonmagnetic material, a magnet housed in the nonmagnetic portion of said tubular body, and two pairs of pole pieces formed of ferromagnetic material including a first pair of pole pieces held in contact with the two poles of said magnet and a second pair of pole pieces disposed outside of the respective pole pieces of the first pair in spaced relation thereto and interconnected therewith by respective magnetic portions of said tubular body.
According to a fourth aspect of the present invention, the lint clearer comprises, a tubular body partly formed of non-magnetic material, a magnet housed in the nonmagnetic portion of said tubular body, and a pair of pole pieces of ferromagnetic material disposed outside of the respective ends of said magnet in spaced relation thereto and interconnected therewith by respective magnetic portions of said tubular body.
The foregoing and other objects, features and advantages of the present invention will be apparent from the following description when taken with reference to the accompanying drawing, in which:
FIG. 1 illustrates one embodiment of the present invention in axial cross section; and
FIG. 2 is a view similar to FIG. 1 illustrating another embodiment of the invention.
Referring to the drawing and first to FIG. 1, there is shown a lint clearer which includes a tubular body 1 in the form of a pipe section of aluminum the pipe wall being perforated as at 2 to reduce the weight of the body. A magnet 3 is housed in the tubular body 1 midway of its axial length and may be cast or formed of ferrite. Pole pieces 4 formed of soft iron or other ferromagnetic material are held in contact with the N and S poles of the magnet. These pole pieces act to redirect the lines of flux emanating from the two poles of the magnet to a direction transverse of the axis of the body 1, when the lint clearer is in operating position. Plugs 5 are made of wood and tightly fitted in the opposite ends of the tubular body 1 to close the ends and each has an integral shank portion 6, which serves as a supporting rod to hold the adjacent pole piece 4 in tight faceto-face contacting relation with the magnet 3. The roller or tubular body 1 Patented Mar. 15, 1966 is covered over the entire periphery thereof with a raised fabric 7.
For use, the above-described lint clearer is brought close, for example, to aligned fluted bottom rollers of a spinning frame while being held parallel to the rollers so as to be attracted thereto and held firmly in a desired position thereon. This is possible due to the fact that the pole pieces 4 held in close contact with the magnet are magnetized by the magnetizing force thereof to have a strong ferromagnetism.
As apparent from the foregoing description, this lint clearer including a tubular body made of aluminum is generally light in weight and rust-proof.
Referring next to FIG. 2, there is shown another embodiment of the present invention including a tubular body 1 including a central nonmagnetic portion 12 and magnetic portions 13 extending in opposite directions therefrom. The nonmagnetic portion 12 is formed of a nonmagnetic metal such as aluminum, copper or any of of their alloys or an organic substance such as synthetic resin, vulcanized fiber or rubber while the magnetic portions 13 are formed of iron. A magnet 3 is housed in the nonmagnetic portion 12 of the tubular body 1 with a pair of pole pieces 4 of ferromagnetic material such as soft iron held in close contact with the N and S poles of magnet 3. The pole pieces 4 each have its peripheral surface in contact with the respective magnetic portions 13 of the tubular body 1. Another pair of pole pieces 16 of ferromagnetic material are fitted in the opposite ends of the tubular body to close the ends. The tubular body 1 is covered over its entire periphery with a sheet of soft resilient material such as raised fabric, cloth or rubber.
When it is desired to use this form of lint clearer, it is brought close, for example, to the underside of a fluted bottom roller 18 of a spinning frame while being held parallel to the roller so as to be attracted thereto and held firmly in a desired position thereon. This is possible due to the fact that the two pairs of pole pieces 4 and 16 have a strong ferromagnetism, the first pair of pole pieces 4 being held in close contact with the magnet 3 to be magnetized under the magnetizing effect thereof while the second pair of pole pieces 16 are magnetized through the intermediary of said first pair of pole pieces 4 and the magnetic portions 13 of the tubular body 1.
Having described two embodiments of the present invention, it will be apparent to those skilled in the art that many changes and modifications may be made without departing from the spirit and scope of the invention as claimed. For example, in the second embodiment the magnetic portion 13 of the tubular cylinder 1 may be extended inwardly into contact with the peripheral surface of the magnet 3 at its opposite ends instead of employing the inner pair of pole pieces 4. The pole pieces 4 may be made to have the same outside diameter as that of the nonmagnetic portion 12 of the tubular body 1. In this case, the tubular body 1 is made in three pieces including a central magnetic section and nonmagnetic end sections, and the nonmagnetic end sections are connected to the central magnetic section by way of the respective pole pieces.
It will be appreciated from the foregoing that the present lint clearer is extremely easy to mount and dismount and can be positioned on a roller as desired since it is held thereon under the magnetic force of the pole pieces magnetized by the magnet housed in the tubular body. In addition, the present lint clearer does not require any special support means, and is usable in any narrow space.
What is claimed is:
1. A lint clearer comprising a tubular body partly formed of non-magnetic material and partly of magnetic material, a magnet housed in the nonmagnetic portion of said tubular body, and two pairs of pole pieces formed of ferromagnetic material including a first pair of pole pieces held in contact with the two poles of said magnet and a second pair of pole pieces disposed outside of the respective pole pieces of the first pair in spaced relation thereto and interconnected therewith by respective magnetic portions of said tubular body.
2. A lint clearer comprising a tubular body partly formed of non-magnetic material and partly of magnetic material, a magnet housed in the nonmagnetic portion of said tubular body, and a pair of pole pieces of ferromagnetic material disposed outside of the respective ends of said magnet in spaced relation thereto and interconnected therewith by respective magnetic portions of said tubular body.
3. A lint clearer comprising a non-magnetic, rigid, perforated tubular body having an equal outer diameter throughout its length; a cylindrical magnet housed in said body; a pair of cylindrical pole pieces housed in said body in contact with each pole of said magnet for redirecting the lines of flux emanating from each pole of the magnet to a direction transverse of the axis of said tubular body, the combined axial length of said magnet and said pole pieces being substantially less than that of said body; a plug member tightly fitted in the opposite ends of the body; a shank integral with and extending out from each of said plug members, the free end of each of said shanks engaging a corresponding pole piece to urge said pole pieces into a tight face-to-face contact with said magnet; and a covering of soft, resilient material covering substantially the entire peripheral surface of the body.
