1 Claim. (Cl. 43-43.13)

This invention relates to a variable depth trolling device for use while fishing from a moving boat or from a stationary position in a current of water.

Conventional trolling devices ordinarily comprise a weighted body which is intended to be sustained at the end of a trolling line at the required depth. At a given speed, any change in the depth of the trolling operation necessarily involves a substitution of the trolling device by another of a different weight, which adjustment results in undue loss of time as well as the necessity of utilizing a number of different devices of different weights to suit various operating conditions.

The principal object of the invention is to provide a highly simple device of the character herein described which does not depend upon weight for determining its depth of operation, but rather, which employs a body having a particular configuration which, when subjected to hydro-dynamic forces, may be quickly and easily controlled as to its operating depth by simply hauling in or paying out the trolling line.

Other advantages of the invention reside in its extremely simple construction, in its efficient and dependable operation and in its adaptability to economical manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a perspective view of the invention;

Figure 2 is a longitudinal sectional view thereof;

Figure 3 is an underside plan view of the same; and

Figure 4 is a transverse sectional view, taken substantially in the plane of the line 4-4 in Figure 2.

With reference now to the views of the drawings the device, as an entity, is denoted by the reference numeral and is characterized by a body 12 having two symmetrical body portions 14 which, in turn, have rearwardly tapered straight lengthwise or side edges 15. These merge into broadly rounded leading edges 16. The body portions 14 have planar top surfaces and these slope upwardly and inwardly from the edges 15 and meet at a dihedral angle edge 17 which defines the axis of sym- 2,749,651 Patented June 12, 1956 metry of the body portions 14. The rounded leading edges 16 meet at the stated dihedral angle edge and consequently define a prow. An upstanding rib 18 is formed integrally with the body portions 14 and it extends along said dihedral edge above said planar top surfaces and it terminates rearwardly of the rounded leading edges 16 in a plane front face 19. The face 19 is disposed perpendicularly to the stated dihedral edge 17. The body portions 14 are characterized in their underneath portions with recess means 20 which extends from the prow at the dihedral edge to the rear end of the body portions and thus defines a concave lower surface portion having its greatest concavity directly beneath the rib. The rib has a plane top surface and also plane vertical sides and these lie parallel to the dihedral edge 17 and extend, as at 21, beyond the rear end of the body portions 14. Any appropriate line attaching means, such as that denoted at 22, is employed and appropriately connected to the rib adjacent the front end 19 thereof.

Since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

A trolling device comprising a body having two symmetrical body portions having rearwardly tapered straight side edges merging into broadly rounded leading edges, said body portions having planar top surfaces sloping upwardly and inwardly from the edges thereof and meeting at a dihedral angle edge defining the axis of symmetry of said body portions, said rounded leading edges meeting at said dihedral angle edge and defining a prow, an upstanding rib integral with said body portions and extending along said dihedral edge above said planar top surfaces and terminating rearwardly of said rounded leading edges in a plane front face, said plane front face lying perpendicular to said dihedral edge, said body portions having recess means in the lower surfaces thereof extending from the prow at said dihedral edge to the rear end of said body portions and defining a concave lower surface portion having its greatest concavity beneath said rib, said rib having a plane top surface and plane side surfaces lying parallel to said dihedral edge and extending beyond the rear end of said body portions, and line attaching means on said rib adjacent the plane front face thereof.
