BOAT-KNEE.
SPECIFICATION forming part of Letters Patent No. 272,603, dated February 20, 1883.
Application led November 8, 1882. (No model.)
To all w/wm it may concer-n Be it known that I, DAVID TRUE, of Salisbury, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Boat-Knees, of which the following is a specification.
This invention relates to that class of boatknees made in two (or more) parts and held to- 'gether at the adjacent or adjoining portions of said parts, and is applied more particularly to knees used in the construction of dories and similar craft.
In the accompanying drawings, in which similar letters of reference indicate like parts, Fig. l is a View in perspective ot' a portion of a boat-knee embodying my invention. Fig. 2 is a horizontal section on line wx, Fig. l. Fig. 3 is a view of one of the side plates removed. Fig. 4 is a plan view ofthe knee, with one ofthe plates moved out of position.
A and B represent the two main portions of the knee, meeting at the bend and held firmly and immovably together by the means below described. Each ot the portions A and Bis provided with vertical or nearly vertical grooves a, cut in its sides, as shown.
C C are strong metallic plates provided with tenons or beads b on their inner surfaces, adapted to iit closely and tightly into the grooves a. The plates C are so placed against the sides of the knee that the joining-line ot' l-the two portions of the knee is between the immovable, so that there is no possible chance of their becoming wrenched apart, or even started, by the great strain to which they are subjected.
In order to prevent any possibility of the wood splitting, especially at the portion of the knee next the scupper-. e., the cut-awav portion at A B-tlanges or bent portions C extend inwardly, as shown, from the plates C, and are pressed tiatly upon the upper and under portions ot' the knee, particularly the latter. These flanges, which are preferably integral with the side plates, may be hammered down upon'the knee after the plates are in position, and thus both plates and liangcs are pressed closely and tightly against the knee, preventing either wrenching at the meeting line or splitting.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
l. In a boat-knee, the combination ot' the two portions A B thereof', provided with the grooves a, vertical, or nearlyI so, and substantially parallel with the meeting orjoining line ofthe two said portions of the knee, and one or more side plates provided with tenons parallel, or nearly so,`and adapted to tit into said grooves, substantially as and for the purpose set forth.
2. Ina boat-knee made in two part-s and having its corner cut away to form a scupper, the combination, with said parts, ot' one or more side plates provided with projections for entering the side of the body ot the knee, and one or more anges, C', substantially as and for the purpose described.
DAVID TRUE.
