keel may be assembled and whereby the ribs of the boat may be assembled upon the keel at the proper stations, aligned in a planevertical thereto or at a predetermined angle therewith, and be secured against movement in any direction` thereupon.
A vfurther object of the invention is to produce a keel of great strength and rigidity for its weight, and adapted to have -asso ciated therewith a stem and a stern postreceived within lthe keel assembly to be held thereby against lateral displacement` and riveted and braced thereto againstangular.
displacement ina vertical mid-plane. l
With these and other objects in view as may become vapparent as the disclosure pro-` ceeds, the invention consists in the novel combination-of elements, construction and arrangement of parts, operation and specific features to be hereinafter enlarged upon and recited in the subjoined claims, the invention being illustrated in the accompanying drawings, wherein: e
Figure 1 is a side elevation of my keel structure;
Figure 2 is a rear elevation thereof;
Figure 3 is an enlarged section on line 3 3 of Fig. 1; A l
Figure 4 is a side elevation of a fragment of my keel;
Figure 5 is a plan of the fragment shown in Fig. 4;
Figure 6 is a section on line 6 6 of Fig. 2; and
Figure 7 is a perspective detail of a fragment of my keel, showing the application of the rib thereto, parts being modified.
Referring more particularly to the drawings the keel proper is formed of two keel platesj and 6 which entend as shown from end to end of the boat. A flat rolled steel bar 7 is interposed between the side plates and riveted thereto as at 8 to space the keel plates at their lower edges. A stem piece 9 of proper bow profile is stepped between the two keel members and is riveted or otherwise secured thereto as at 10. A brace `11 may be welded or otherwise secured to they stem as at 12 and extend to enter betweenl the keel plates where it may be riveted thereto as at 14. y l Y A stern post 15 is similarly mounted be tween the keel plates and riveted therebetween as at 16 and braced therefrom as at 17. In lorder to provide a greater bearing surface to which may be riveted or otherwise secured the plates forming the stern, this stern post has secured to it on each side angle bars 18, secured vthereto as by rivets 19, and having rivet holes 2() to which the stern platesare fastened. A
VThe side members ofthe keel may be stamped from a sheet or maybe builtup7V aind'in the stamping operation lugs 21 may be formed or leftalong the upper-edge. of each keel piece, and earsv 22-may be turned at right angles therefrom to form a vflat bearing surfkacevfor aligning the ribs in a vertical plane at a. right` angle to the plane of the keel and may beperforated as at 24;
so that the -ribs`26 of the boat structure may be securedtherethrough as by rivets 25.
`'l`heseribs26,.when riveted to the ears,
serve to space the side plates ofthe keel while the lugs of the keel hold the ribs in spaced relation thereupon.
The ears and the ribs may be cut away as at 27 so that a flat rolled steel bar 28 may be set therein, its outer surface to lie flush with the edge ofthe rib and ear so that thev bottom plates may have a secure bearing thereupon, and this flat steel bar or keelson may be welded to the side Vof thev keel mem-v bers to strengthen the same against lateral bending.
It will be appreciated that such a structure will be less expensive to build and is designed for great strength and lightness and in such manner as to permit standardized production methods, the keel being built of three pieces and comprising but two plates and a bar riveted together and having ears integral therewith to which the ribs may be secured, eliminates lthe usual labor and eX- pense in the attachment of clips riveted to the keel and tothe rib at each rib station. The design permits working the keel section in a press at a great saving of labor and to absolute accuracy whereas separate clip angles cannot be made to absolutely accurate dimensions, .except at much greater cost for layout and handling. The bar is used to separate the plates at the-bottom to increase the strength atthe short dimension with a saving of Weight.
While in the foregoingY l have described specific embodiments and have mentioned only certain modifications, it Will be appreciated that in practice I do not limit myself to such specific details as herein set forth, but `may resort to any practical modiications falling Within the scope 0f the Claims;
' lhat I claim is: l
l. A keel comprising side members, agspacing strip secured to the side members at the lower edge thereof, lugs on the upper edge ot the side members defining the rib stations, and ears bent from the' plane of the side members on opposite sides of the keel and delining the plane of the ribs.
2. A keel comprising side members, a spacing member therebetween, lugs at the rib stations integralv with the side members to space the-ribs along the-keel, ears bent from the lugs to align the ribs, and' a keelson secured to the side members and associated with the ears to brace the side members aga-inst lateral bending. s
3. In? boat structure, a. keelE comprising a plurality of` longitudinal members; a stem,
. and aV stern post, positionedbe'tween and em'- braced by the keel members; bracing between'the stem and keel, and the stern post and keel, having footingsl between the` keel members; ribs along the keel tojliol'dv the keel members in' spaced relation'fat their upper' edges; and lugs struck from thefkeel to p0- ,sition and secure the ribs in spaced relation.
4. A keel comprising a plurality of spaced 6. AV boat keel comprising spaced sideA members, aligned lugsl on the' edge of the side members delining the rib stations, yand' aligned ears bent-from the planei of the side members at a' thereto.
7. A keel comprising a plurality of spacedv longitudmalk members,- eachk having' lugs ,inv
lateral alignment Witl'r the' lugs onv an adjacent spaced member, said lugs rising from the'edge of the spaced members and defining the rib stations'. v
8. A keel comprising a plurality olfv long-L tudinal members Whose upper edges defineY the plane from Whichl the boat ribs spring,
lugs defining the rib stations, and ears intepredetermined angley gral With the lugsand With the longitudinal membersbe'nt from the lugs and deiiningthe plane of the ribs. s
9. A keel comprising' a pluralityI of longiL tudin'al: members Whose upper edges define thevplane from whichv the boatribsspring, with ears bent from the .plane of the longitu-y dinal membersv anddenin'g Witlrthe upper edges thereof anV angle such'y that the;` rib when positioned" will risein/ a: vertical plane.
