METHOD OF CONSTRUCTING BOATS Filed July 14; 1952 2 Sheet's-Sheet 1 Ole K. Gran/i Arno/d Gran/i INVENTORS 1954 0. K. GRONLI ETAL METHOD OF CONSTRUCTING BOATS 2 Sheets-Sheet 2 Filed July 14, 1952 Ole K. Gran/i Arno/d Gran/i IN VEN TORS i aq,
United States atent flice 2,697,235 Patented Dec. 21, 1954 This invention relates to new and useful improvements in methods of boat construction and the primary ob ect Another important object of the present invention is to provide a method of constructing boats that Will produce a stronger boat by bracing toward the keel as the boat is built.
Another feature of the present invention is to provide a method of boat construction that avoids the necessity of steaming planking or strips as the same are applied, therefore resulting in a more water-tight boat.
A further object of the present invention is to provide a method of boat construction wherein the gunwale is constructed prior to the application of the keel avoiding the necessity of having tapered planking or strips from back and rear in order to get the gunwale in the desired height or position.
A still further aim of the present invention is to provide a method of constructing a boat that is extremely simple and practical and which avoids the costly process frequently followed in constructing boats.
merals refer to like parts throughout, and in which:
Figure 1 is a perspective view of the shell or frame on which the present boat is constructed;
Figure 2 is a perspective view of the frame showing the initial steps of constructing the boat thereon by applying the inside stern, ribs and transom;
Figure 3 is a perspective view showing planking secured to the transom, ribs and inside stem starting from the gunwale;
Figure 4 is a group perspective view showing the boat completed and removed from the frame;
Figure 5 is a vertical sectional view taken substantially on the plane of section line 5-5 of Figure 4; and
Figure 6 is a sectional view taken substantially on the plane of section line 6-6 of Figure 4 to ner in which the keel is secured to the back end of the inside stem while abutting the back end of the outside stem.
the like.
As the strips screws holding the ribs to the frame 2 are removed befo e their accommodating apertures are covered by the strips.
After all of the strips 28 have been ends of the strips are trimmed flush with the mslde stem to the back end 26 and is also fastened to the transom 22.
The boat B is then removed from the frame 10 making sure all screws holding the boat to the frame were reinvention, what is claimed as strips fiush with the side edges of the first stem;
securing the of the first frame.
