IMPROVEMENT IN FISHING-LINE vSINKERS.

Specification forming part of Letters Patent No. 56,857, dated July 31, 1866..

To all 'whom it may concern.-

Be it known that I, JOHN R. MARTIN, of Boothbay,in the county of Lincoln and State of Maine, have invented a new and Improved Fish-Sinker or Fishing-Lead; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings', and to the letters of reference marked thereon.

Figure l is a perspective view, and Fig. 2 a side elevation and section.

A is a body or weight of lead or other soft metal. B B is a plate of copper, composition, or other hard metal. C is a staple, bolt, or slide. D is a thumb-screw. E is a bar of copper, composition, or other metal, called the hawse77 F is a swivel. H is a stop-screw. K is a slot, and L a space or month in the staple C, which is movable.

The body or weight of lead or other metal A is run or molded in any desired form or size, corresponding upon its face-surface with the plate B B, to which it is attached and held by screws inserted ad Zt'bitum, and also by the screw S of the hawse, the screws D and H, and the screw I, inserted in the upper-end to hold it firmly from working loose.

In molding the lead space should be left for the insertion of the'movable staple of copper, composition, or other metal, which, after being pushed into the full depth of such space or cavity, is held there firmly by the screw D, as seen in Fig. l, where it appears as a staple, to which is attached the swivel F, or a line instead of such swivel.

When the screw D is removed the staple O may be readily pulled up until the lower part of the slot K strikes the screw H, which acts as a stop, and leaves the staple I) with its mouth L open for the admission or removal of a swivel or line, as shown in Fig.. 3; or, if desired, the stop-screw H may also be removed, and the staple or bolt C can then be removed at pleasure. l

What I claim as my invention is- 1. The movable staple, bolt, or slide inserted in the top of the sinker beneath the plate, with a mouth or space for the admission of a swivel or line, which is opened or closed at pleasure, as described above, by means of which the sinker is readily detached from the line.

2. The connection of a plate of hard metal with a body of soft metal, each of which is made separately, as well as the movable staple, and either of which may be supplied anew at pleasure.

JOHN R. MARTIN.
