ATTORNEY Patented Nov. 25, 1952 UNITED STATES PATENT OFFICE SHOT SPLITTING PLIER-S Henry G. Frazee, Grand Rapids, Mich.

Application May 20, 1949, Serial No. 94,297 I 1 Claim.

This invention provides a tool for applying split-shot sinkers to a fish line, and removing the same therefrom. In appearance, a tool embodying the present invention roughly resembles a pair of pliers. A pair of handles are provided which are to be grasped by the user for the application of the required force to operate the jaws of the device. These jaws are equipped with means for separating a split shot along the parting line to remove it from a position in which it has been clamped on the fish line. Means are also provided on the jaws for facilitating the clamping of the shot in position as required. This general type of device is not new, but the action of the jaws and the construction of a device embodying the present invention present advantages which are not to be found in the prior art.

Similar to the usual pair of pliers, each jaw member of a tool embodying the preferred form of the present invention is associated with a handle. The two components of the tool thus formed (each having a jaw and a handle portion) are pivoted together so that the torque applied by the user is transmitted to the jaw members causing the same to come to the fully closed position. One of the jaw members is provided with an entering edge adapted to engage the split shot at the parting line, and force the same open as the jaws are brought to the closed position. The action of this edge is very similar to the action of a wedge driven into a split in a log, and is not to be confused with a cutting action. The opposite jaw member is provided with a receiving surface against which the shot is placed during the closing action of the tool. Preferably. this receiving surface is so formed as to have a natural tendency to locate the shot approximately under the entering edge to avoid the necessity of carefully positioning the shot manually during the operation of the tool.

In the preferred form of this invention, the entering edge is disposed transversely to the general plane of rotation of the jaw members. This arrangement provides for the maximum of clearance in the jaw members for the construction of other surfaces which will be discussed hereinafter. It is possible, however, to arrange the opening edge in a direction generally parallel to the plane of the rotation of the tool components, but this construction results in a somewhat larger tool necessary for performing the same functions with a given force and range of travel of the moving members. The receiving surface noted above may be arcuate in a plane parallel to the plane 2 I of articulation of the tool, and may also be arcuate in a plane perpendicular thereto. The curvature, of course, is concave in both places in order to generate the tendency to locate the shot in the position required.

The various portions of the jaw members noted above are so disposed relative to each other that the tool will not completely sever the shot when brought to the fully closed position. Preferably, a set of stops are provided which limit the movement of the jaws toward the closed position. Such stops may be most conveniently provided by a set of auxiliary clamping surfaces disposed at the front end of the pliers which may be serrated in the conventional manner so as to make this fishermans tool'also usable to perform the conventional functions of a pair of pliers. This arrangement enables the device to be used'for the extraction of fish hooks, the repair of tackle, and so forth.

At one side of the entering edge discussed above (with respect to the pivoting point of the tool) and arcuate recess is preferably provided which has the dual function of providing clearance for the action of the edge and also providing a fsecondary receiving surface adapted to cooperate with the principal receiving surface opposite the opening edge in order to facilitate the clamping of the shot to the closed position. This arcuate recess is preferably approximately the same curvature as that of the shot, and renders the holding of the shot in position during the closing action a very simple matter.

The various features of the present invention will be discussed in detail by an analysis of the particular embodiments illustrated in the accompanying drawings. In these drawings.

Figure 1 is a view taken in elevation of a tool embodying the present invention, with a split shot in position under the entering edge at the beginning of the opening operation,

Figure 2 is a view taken in projection with respect to Figure 1, with a portion of the lower jaw of Figure 1 broken away to show the opening edge.

Figure 3 is a view of the same tool illustrated in Figure 1, with the components in the fully closed position. This view illustrates the action of the tool as it opens the shot along the parting line thereof.

Figure 4 is a section through the jaw components of a modified form of the present invention.

Referring to Figure 1, the tool is shown generally composed of the two components desighated as In and H. These components are pivoted at l2. The component I comprises the handle portion 13 and the jaw portion 14; while the component ll comprises the handle portion [5 and the jaw portion 16.

The jaw portion i6 is provided with the enterme: edge [1 adapted to enter the parting line of the shot and cause the same to open sufiiciently to release the fish line as shown in Figure 3. Disposed forwardly of the edge I! is-the arcuate recess I8providing clearance for the shot as the edge I! moves to the closed position, and also, providing a holding recess in which an open shot may be received as it is being forced into a closed position on the fish line. 7 j

The split shot designated as l9 is shown received on the arcuate surface 20,' the-vcurvature of which tends to hold the shot in position for the operation of the edge I]. In the view shown in Figure 1, the shot 19 is securely clamped upon thefish line 2|; The curvature of thereceiving surface 20'is such that the forward portion thereofxis adapted-to cooperate with therecess 18 in V :o'rder to providethe clamping actionnecessary to close the shot into the position noted in Figure 1. The

serrated gripping surfaces

22 and 23 perform the dual function of limiting stops pre- .ventingthe jaws from closing to a point which iwouldicause the completeseparation of the split -shotuand also the function of providing the usual clamping; surface to be found on conventional pliers.-. v j I: The iviewshown in Figure 4 presents a modified form ofthe present invention in which the opening edge performs the same function as -the.:edg'e [:1 shown in Figure 1. The edge 24, -.-ho.wever, isdisposed generally in a plane parallel to the plane of articulation-of the tool. The arrangement shown in Figure 4 requires a slight increase in the length of the jaw member of the-tool, and therefore results in a less com- :pact device than that shown in Figure 1. The ,aFlgure 4 arrangement is preferably; provided illustrative purposes only.

clamping surfaces

22 and 23, and other structure similar to that shown in Figure 1.

The particular embodiments of the present invention which have been shown in the accompanying drawings and described herein are for It is the intent of the inventor to claim the entire scope of the invention to which he is entitled in view of the prior art.

I claim: I

A tool for opening split shot, said tool comprising: a first jaw member; a portion extending from said first jaw member and having an engaging edge; a second jaw member pivotally connected to said first jaw member for rotation in one plane, and having an arcuate receiving surface 'of acurvature substantially smaller than that of the spherical surface. of said shot :ata point opposite said engaging edge, the'jcenter of curvature of said receiving surface at said point being substantially on a line tangent to said pivotal connection at said point; and handle means associated with each of said jaw membars for closing and opening the same'.
