Application April 18, 1958, Serial No. 729,394

9 Claims. (Cl. 114-224) This invention relates to an improved calking tool for calking seams of boat hulls.

The primary object of the invention is to provide a calking tool of this kind, which 'can also be used for calking other than boat hull seams, which is designed for use on beams of a boat cradle beneath a boat hull supported thereon, for calking seams, such as garboard seams, which cannot usually be successfully reached and calked with ordinary calking tools, without jacking or otherwise displacing the hull relative to the cradle, so that much time, labor, and expense are saved in such calking operations.

Another object of the invention is to provide a more practical, inexpensive and efiicient tool of this kind which is composed of a minimum number of simple and easily constructed parts, including a fulcrum base, a lever rockably supported on the base, and a calking iron mounted on the lever, the lever being adjustable on the base for reaching seams remote from or near to the base and for obtaining different desired leverages, and the calking iron being rotatable and swingable on the lever to reach and calk seams disposed at various angles, the iron being readily interchangeable with calking irons of difierent contours for different specific calking operations.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

Figure 1 is a top plan view showing a calking tool of the invention mounted on a boat cradle beam;

Figure 2 is a side elevation, partly in vertical section, showing the tool mounted on a boat cradle beam beneath a boat hull on the cradle, with a calking iron in relation to a hull seam to be calked;

Figure 3 is an exploded perspective view of said tool;

Figure 4 is a side elevation showing said tool support on a boat cradle beam, with the lever of the tool in elevated position in full lines, and in depressed calkingiron applying position in phantom lines;

Figure 5 is an enlarged vertical transverse section, taken on the line 55 of Figure 4, showing a calking iron in erect position on the lever, in full lines, and in canted or tilted position in phantom lines;

Figure 6 is an enlarged fragmentary vertical transverse section taken on the line 6-6 of Figure 4; and

Figure 7 is an edge elevation of a straight form of calking iron.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the numeral 10 designates a beam of a boat cradle, upon which the'keel 12 of a boat hull 14 is shown restthe garboard seam 18a next to the keel 12, and seams 18 adjacent thereto with ordinary calking irons (not shown), and to provide sufficient room to swing hammers against the calking irons for driving calking material 20 into such seams. The tool of the present invention provides for quicker, easier, and more efficient calking of garboard seams 18a and adjacent seams 18 while the hull 14 rests upright upon the cradle beams 10, and without elevating or tilting the hull 14 relative to the beams 10. r

The illustrated calking tool of the invention, generally designated 22, comprises a fulcrum base 24, a lever 26, and an interchangeable calking iron 28.

The base comprises a flan-preferably rectangular base plate 30 having fixed thereon, as by welding 32, along a center line thereof, an upstanding fulcrum standard 34, which is preferably a flat plate having upwardly converging end edges 36, and a horizontal longitudinal upper edge 38 having therein a centralized transverse notch 40 having parallel sides 42.

The lever 26 comprises an elongated, preferably flat and straight bar 44 arranged in a vertical plane and in a generally horizontal position, and having upper and lower longitudinal edges 46 and 48, and a preferably rounded rear end 50.

The forward end of the lever bar 44 is forwardly and downwardly tapered, as indicated at 52, and an elongated preferably flat bar 54- has a rear portion 56 secured, as by welding 58, upon the upper edge 46 of the lever bar 44, a forwardly declining intermediate portion 60, secured as by welding 62, to the forward end 52 of the lever bar 44-, and a depressed forward portion 64, which parallels the rear portion 56, and is preferably flush with the lower edge 48 of the lever bar 44. The forward portion 6d constitutes a calking iron seat 68 and has a preferably rounded forward end 65. Concentric with the forward end 66 of the seat 68 is a round hole 70 having a downwardly beveled side wall 72.

The calking iron 28 comprises a cylindrical shank '74 slightly smaller in diameter than the smaller upper end of the hole 70 in the seat 68, and has a threaded lower end portion 76, which, when the iron 28 is operatively positioned in the hole 70 is below the seat 68, and an upwardly tapered upper portion 78 which is positioned above the seat 68. Preferably integral with and rising above the upper portion 78 is a preferably fiat bit 80, which is upstanding from and longer than the shank 74, and is substantially wider than and projects beyond opposite sides of the shank 74, so as to define shoulders 82 at the lower end of the bit 80 to bear upon the upper side of the seat 68. A nut 84 is removably threaded on the lower end portion 76 of the calking iron shank 74 so as to retainably bear against the under side of the seat 63, the nut 84 being normally spaced at such a distance from the shoulders 82 that the calking iron 28 is free to move upwardly and downwardly relative to the seat 5%, and to tilt or cant sidewise, to angles relative to the perpendicular, limited only to the angle of the beveled side wall '72.

The calking iron bit 80 has a straight upper edge 8 6,

ing, the boat hull 14 having a bottom 16 having therein to 5, or straight as shown in Figure 7 or have other curvatures suitable to calking operations to be performed;

1-0"beneath"a b'oat hull 14, "as indicated in Figure 2.

The lower edge48 of the lever 26 is then engaged in the notch 40 of the fulcrum standard 34 of the base 2 4, a suitable calking iron 28 having been mounted and se:

cured in the hole 70 of the seat '68. The lever 26 is then worked through the notch 40 so as to properly position the calking iron 28 relative to a boat hull seam to be calked and to obtain the desired leverage in op 4. A calking tool comprising a fulcrum base, a lever having forward'and rear ends, a'seat on the forward end of the lever, and an upstanding calking iron mounted on the forward end of said lever, an intermediate part of said lever bet-ween its ends being rockably engaged on said fulcrum base, said fulcrum base comprising a flat base plate having an upstanding fulcrum standard thereon upon which saidl'eve'r is fulcrumed, said standard crating the lever 26. Calking material, such as cotton H and oakum, having been applied in the seam to be calked, pressure is then applied downwardly upon the rear end part of the lever 26, in a manner to elevate the calking iron 28 and apply the upper edge 86 of the bit 80 to and force the calking material into the seam and thereby calk the seam.

The described loose mounting of the calking iron 28 Figure 1, the rear end it of the lever bar 44, projects beyond the side of the boat hull 14, so that this end of the lever 26 is freely accessible to be struck by a hammer or mallet, when desirable or necessary, in calking operations, without interference from and danger of striking cradle beams or portions of the boat hull with the hammer.
