Abstract
Sacrificial anodes and line cutters which are formed into a single unit.
Description
- This invention relates to marine equipment and is particularly directed to improved sacrificial anodes and line cutters.
- This invention is described in my copending Provisional Application, Ser. No. 61/277,342, filed ______, and now ______.
- It has long been known that, because various types of metals are used for different parts of a boat, exposure to water, especially salt water, creates electrical currents which tend to erode the metal parts. This results in weakening or failure of the effected part. As a result, it has become common practice to provide sacrificial anodes, usually formed of zinc or some other inexpensive and chemically active metal, which will erode more rapidly and, hence, serve to protect the more valuable parts. It is also known to provide cutters in the propeller shaft or the like to protect against entanglement by water plants, fishing lines and the like. However, prior art line cutters and sacrificial anodes have been provided as separate items. Therefore, it has not been possible to provide both sacrificial anodes and line cutters in many locations, such as propeller shafts. Thus, none of the prior art sacrificial anodes or line cutters have been entirely satisfactory.
- These disadvantages of the prior art are overcome with the present invention and improved sacrificial anodes and line cutters are provided which can quickly and easily be installed in common in substantially any desired locations, such as propeller shafts, simultaneously.
- These advantages of the present invention are preferably attained by providing improved sacrificial anodes and line cutters which are formed into a single unit.
- Accordingly, it is an object of the present invention to provide improved sacrificial anodes and line cutters.
- Another object of the present invention is to provide improved sacrificial anodes and line cutters which can be installed quickly and easily.
- A further object of the present invention is to provide improved sacrificial anodes and line cutters which can be installed quickly and easily in a common location.
- An additional object of the present invention is to provide improved sacrificial anodes and line cutters which can be installed quickly and easily in common si substantially any desired location.
- A specific object of the present invention is to provide improved sacrificial anodes and line cutters which are formed into a single unit.
- These and other objects and features of the present invention will be apparent from the following detailed description, taken with reference to the figures of the accompanying drawing.
-
FIG. 1 is an isometric view of a combination sacrificial anode and line cutter embodying the present invention; -
FIG. 2 is a top view of the device ofFIG. 1 ; -
FIG. 3 is a top view of an alternative form of the device ofFIG. 1 ; -
FIG. 4 is an isometric view of another alternative form of the device ofFIG. 1 ; -
FIG. 5 is an isometric view of showing three of the devices of the present invention mounted on a propeller shaft; and -
FIG. 6 is an isometric view of an alternative form of the device ofFIG. 1 . - In that form of the present invention chosen for purposes of illustration,
FIG. 1 shows a sacrificial anode and line cutter, indicated generally at 10. Thesacrificial anode 10 is an annular device formed of chemically active metal, such as zinc, aluminum or the like, comprising upper and lowersemicircular halves cutter blade 16 is formed of strong, rigid non-metal material, such as carbide, and is also formed in upper and lower halves and is formed with cuttingteeth 17, which project beyond the perimeter of thesacrificial anode 10. Thecutter blade 16 is formed into a single unit with thesacrificial anode 10 as seen inFIGS. 1-7 . The upper andlower halves sacrificial anode 10 are secured together and thesacrificial anode 10 is secured to apropeller shaft 24, as seen inFIG. 5 , or other suitable location bybolts 18. Thebolts 18 pass throughsuitable holes 20 formed in theupper halves 12 and are received in threaded holes, not shown, in thelower halves 14. Theholes 20 and 22 may be located on the same side of thecutter blade 16, as seen inFIG. 2 , or may be located on alternate sides of thecutter blade 16, as seen inFIG. 3 . Obviously, various sizes of thesacrificial anode 10 may be provide to accommodate different diameters of propeller shafts. - In use, because the
cutter blades 16 are molded into the upper and lower halves, 12 and 14 of thesacrificial anode 10, thesacrificial anode 10 becomes a single unit including thecutter blade 16. Thus, when thesacrificial anode 10 is mounted onto apropeller shaft 24 or the like, thecutter blades 16 are also mounted in the same location. Should fishing lines, ropes, kelp seaweed or other material become tangled about thepropeller shaft 24, theteeth 17 of thecutter blade 16 will rapidly shred and sever them to prevent them from interfering with the functioning of the propeller 26. Thesacrificial anode 10 serves in the usual manner to protect the propeller blade and shaft from electrolytic corrosion. -
FIG. 6 shows asacrificial anode 34 having acutter blade 36 attached thereto byscrews 38 to form an integral unit. - Obviously, numerous other variations and modifications can be made without departing from the spirit of the present invention. Therefore, it should be clearly understood that the forms of the present invention described above and shown in the figures of the accompanying drawing are illustrative only and are not intended to limit the scope of the present invention.
