WITNESSES v I INVENTOR EILAIRIE' J. FACKENTHALL, OF TRENTON, NEW JERSEY.

rIsHIne-smmsn.

To aZZ'w/wm it may concern Be it known that I, HART J. FACKEN- THALL, a'citizen of the United States, re-

siding at Trenton, in the county of Mercer and State of New Jersey, have invented certain newv and useful Improvements in Fishing-Sinkers; and I do hereby declare the,

following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.

It is the object of the present invention to provide a sinker fordeep sea fishing, and more particularly to provide asinker so shaped that it may be cast a long distance and will carry the line withouttwisting and also willv sink quickly through the water without being materially deflected from its original direction irrespective of the. roll of the surf or the flow of the tide, and ultimately will anchor the line to the ocean bottom without substantial danger of a change in position irrespective of strong ocean currents. V r

The particular advantages of a sinker constructed" in accordance with the present invention are hereinafter set forth in more detail, reference being bad to the accom-.

panying-drawings, in which Figure l is a perspective view of the completesinker; Fig. 2 is a top view of the same; Fig. 3 is a side elevation, and Fig. 4 shows the sinker as viewed from its narrow or bottom end.

In the construction illustrated, the sinker is of metal and preferably of heavy metal, such as lead or an alloy, and has embedded in it and permanently attached, a' loop of wire, 1, to' which the fishing line may be secured. The sinker is of conical shape, but wlth triangular cuts extending from base to apex, thereby forming five or a similar number of fins or arms, 2, grouped sym metrically about the central solid portion or core of ,the sinker. Preferably, these fins are of substantial width at their exposed edges, and .in cross section each is of triangular outline, as clearly indicated by the figures of the drawing. 7 At the apex of the cone, all of the fins converge to a blunt point, 3, while at their other ends these 'fins form a star shaped structure, as illustrated by Fig. 2. Preferably, the upper edges of each fin are beveled off at 4:, thereby eliminating the sharp corner which otherwise would exist at that point, and also havlng the efiect Specification of Letters Patent.

of producing a relatively sharp corner 5 at the extreme outer part of each fin. These outer corners are very effective in preventmg the weight from rolling over a sandy bottom under the nfluence of a strongtide or surf, for they are capable of digging into the sand and giving a firmanchorage to the line, and furthermore prevent free rolling of the sinker on the ocean bottom.

It has been found in practice that a sinker constructed as above described can be cast farther than a round sinker of equal weight, and with less turning or twisting While in the air, and with less strain on the line which is being thrown. The conical shape of the "sinker cuts down the air resistance to its flight, and the projecting finssteady it "in flight and prevent it fnom whirling while traveling with the line. Also, the steadi- 'ness, given to its flightby the projecting fins, holdsthe sinker to its original direction and prevents the curving or swerving which might occur particularly in a strong wind if the sinker were not thus held against rapid whirling or spinning. I

When the sinker; strikes the water, 1ts. e

center of gravity is so positioned that it cuts through the water quickly and reaches the bottom without being whirled by the surf or greatly deflected by the t1de. It goes down quicker than a spherical 'we 1ght, and is substantially free from the 'driftlng which characterizes the descent of an ordinary sinker through rapidly moving water. When the sinker reaches the bottom, ,1t strikes on its apex and will either-embed 1tself in the bottom or turn over on its side,

so that the projecting and relatively 'sharp' corners' 5*can dig into the bottom and give anchorageto-the fishing line.

The sinker may be of any desired size and weight, and may vary fromthe relat1veproportions shown in the drawmg, as 1am. well aware.

I claim:

1. A fishingsinker of compact ing projecting fins radiatmg from a SO-lld core in which the center-of gravity 1188, and a line anchorage in the center of the widest portion of the sinker .andnear the center of gravity. W

form hav 2. A' fishing sinker, consistingsof a solid,

tapering central core, a pluralityof project-' ing fins radiating therefrom and converging until they meet at an apex, the center of gravity lying in the central axls of the core the center of gravity of the sinker lying in said core and below the tops of said fins and a line anchorage in said core opposite said apex and near said center of ravity.

4. A fishing sinker of conical shape consisting of a central core with means for attaching a line thereto,oand a plurality of fins symmetrically disposed about said core and converging at the apex of the cone, the

' center of gravity lying in the central axis of thecone and belowthe tops' of said fins,

mama? said fins with said core forming a fiat star shaped base.

5. A fishing'sinker of conical and sym metrical outline having-a wire loop embedded therein to form a line anchorage at the base of the cone, said sinker being cut away from base to apex to form fins converging at-the' apex of the cone, the other ends of said fins being beveled along their sides and forming points to anchor the sinker to the ocean bottom. V In testimony whereof aflix my signature, in the presence of two wltnesses.
