BACKGROUND

1. Field of Invention

This invention relates to a casting float or bobber/sinker that can either slide freely on the fishing line or can be attached in a fixed position.

2. Description of Prior Art

Many fishing float/sinkers devices have been invented in an attempt to solve some of the fisher's problems in regards to making a float/sinker that can be used in several ways to accommodate the needs of the fisher without his having to use multiple numbers of sinkers and floats. A superior float/sinker should include the following qualifications:

- (a) be compact
- (b) protect fishing line
- (c) can change buoyancy
- (d) be light-weight
- (e) have few parts
- (f) saves time
- (g) easy to manipulate
- (h) free of moving parts
- (i) be cost-effective
- (j) be versatile
- (j) be durable

These prerequisites have been only partially addressed to date in manufacturing of float/sinkers even though many types of these devices have been proposed over the years. Accordingly, some of the prior art are detailed below along with objections to each.

U.S. Pat. No. 2,693,049 to Atton in August 1949 has a central passageway that requires fishing line to be cut and threaded through. Predetermined weight
U.S. Pat. No. 2,726,474 to Soskice in December 1955 must be put on line in proper direction for casting or the plug becomes loose allowing water to go in or out of the body and thus changing weight of float. Line is tied to outside of float. It is not desirable to tie knots in fishing line.
U.S. Pat. No. 2,827,731 to Haynes in March 1958, the fishing line must be cut in order to thread line through central tube in order to attach Reverse operation to remove float to put water in cavity. Operation must be done under water all the time keeping the tube in correct position in order to keep water from escaping.
U.S. Pat. No. 3,273,278 to Lynch in September 1966 is objectionable because floats and sinkers would be of different sizes to obtain desirable weight. It would necessarily need to be made of suitable material to make the change.
U.S. Pat. No. 12,060 to Hoard in December 1854. The fishing line being threaded through the central portion of the float/sinker has to be cut and retied. There is only a small opening at ends of float/sinker to receive material for changing weight and buoyancy.
U.S. Pat. No. 3,736,690 to Witkowski in June 1973. The fishing line must be cut and threaded through central portion of float and tied, then, cut again to remove fishing line. Weights similar to a steel washer are used to change the weight of the float/sinker. These changes are very time-consuming.
U.S. Pat. No. 4,202,128 to Hill in May 1980 has adjustable parts that are recommended to be lubricated, a practice which would attract grit and dirt to an oily part. Expensive to manufacture and also needs a tool to make adjustments.
U.S. Pat. No. 4,351,128 to Sivertsen in September 1982. The float/sinker is made of various densities of materials thus requiring multiple items which are cost prohibitive to manufacture.
U.S. Pat. No. 6,467,214 to DeFrisco in October 2002 must be assembled on fishing line in proper direction. Has small opening to add or diminish weight. Must be held under water to fill cavity and reposition tapered pin while submerged.

In addition to checking out multiple patents (only a very few had float/sinker combinations), catalogs have been perused related to fishing gear, sporting good stores have been frequented in several states to determine if there is a sliding/float sinker devise which meets the previously mentioned criteria of a fisher. To this date, this inventor has found no such devise.

- (b) to provide a float/sinker that is easy to cast;
- (c) to provide a float/sinker that allows an easy change of weight;
- (d) to provide a float/sinker that needs no threading through central passageway;
- (e) to provide a float/sinker that does not damage fishing line;
- (f) to provide a float/sinker that is cost effective, meaning it will be inexpensive to manufacture;
- (g) to provide a float sinker that is durable and can be used repeatedly;
- (h) to provide a float/sinker that is free from moving parts that may need to be repaired or replaced;
- (i) to provide a float/sinker that requires no lubrication that could attract dirt, lint, etc.;
- (j) to provide a float/sinker with a cavity to hold additional weights;
- (k) to provide a float/sinker that is easy to load or unload different sized weights, weights that can be changed without removing fishing line;
- (l) to provide a float/sinker that slides freely on the fishing line or conversely provides positive attachment if desired.
- (m) to provide a float/sinker with a means of quickly attaching or detaching a hook, lure, or fly from the float/sinker.

DESCRIPTIONâ€”1 THROUGH 6B

A typical embodiment of the current sliding float/sinker is illustrated in FIGS. 1-6B, the float/sinker comprising four separate components. The main component is the hollow body 13 FIG. 5 (vertical view) and FIG. 3E (vertical view). The three remaining components are the snap-on cover 22 FIG. 3D (vertical view), the cover 22 being shown snapped in place in FIG. 3B. (side vertical view). Another component, the insert 25 is shown in FIG. 4A (top vertical view), FIG. 4B (vertical side view), FIG. 4C (vertical bottom view), and in FIG. 4D (end view). The last component, the retainer 41, is shown in FIG. 6B ((vertical view) with attachment ring 40 at each end. FIG. 6A (vertical view) shows retainer 41 in place in body 13 of float

FIG. 1 shows the sliding float/sinker fully assembled with the insert 25 in place creating a passageway for fishing line 37 with cover 22 snapped in place. FIG. 2 shows three main parts in relation to each part: the snap on cover 22 with shank 19 that shows rib 18 and matching rib 28 in cavity 33. The whole body is preferably oblong but is not limited to that shape. It is of a dimension that serves the desires and preferences of the fisher.

Operationâ€”1 through 6B

The manner of using the float/sinker is both simple and easy as made apparent when viewing FIGS. 1, 2, 3, 5, FIGS. 6A, and FIG. 6B. A cover 22 (FIG. 1) is removed from opening of cavity 33 (3E). Added weight of chosen material is placed within the open cavity 33. The cover 22 (FIG. 5) is then replaced. The cover 22 is held in place by the meeting of rib 18 on shank 19 and on complimentary rib 28 (FIG. 3G) inside of cavity 33. The act of snapping the cover in place keeps the added weight in place. Next the fishing line 37 (FIG. 5) is placed in slot 12 (FIG. 2) followed by placing the insert 25 (FIG. 2) into same slot 12. Then the appendage 23 (FIG. 2) at each end of the insert 25 is fitted into the notch base 14 (FIG. 2) with opposing snaps 15 and 26 (FIG. 2) pressed in place at each end, thus creating a passageway for fishing line 37 and for the float/sinker (FIG. 1) to freely slide on fishing line.

To give positive or fixed attachment to fishing line 37 and leader, not shown, and provide rapid, secure and easy attachment of the float/sinker (FIG. 6A) to fishing line 37 FIG. 6A), place the retainer 41 (FIG. 6B) with rings 40 (FIG. 6B) on opposing ends, into slot 12 (FIG. 2) of body 13 (FIG. 2) Retainer 41 (FIG. 6B) is secured by snapping insert 25 (FIG. 2) into slot 12 (FIG. 2) in a fixed position. To easily remove the cover 22 (FIG. 1) use the small slot 27) on each end of cover 22 for finger nail removal. Likewise, on the insert 25 (FIG. 2), there is a small slot 27 (FIG. 2) on each end of appendage 23 (FIG. 2) for finger nail removal.

There can be round objects such as marbles, not shown, that can be placed in float cavity 33. When these objects move from the motion of the water, there is a vibration and noise that can attract the fish.
