JIG FOR THE ASSEMBLY OF FRAMES OF BOATS Filed April 20, 1939 2 Sheets-Sheet 2 Patented Feb. 11, 1941 UNITED STATES JIG FOR THE ASSEMBLY OF FRAMES OF BOATS Hubert Scott-Paine and James, Wrann, Hythe, Southampton, England; said Wrann assignor to said Scott-Paine Application April 20, 1939, Serial No. 269,018 In Great Britain April 22, 1938 7 Claims.
This invention relates to a jig which is adapted to locate in correct angular relationship during assemblage the members of any of a number of different polygonal transverse frames of a boat and has for its object to provide a simple and inexpensive construction of device which will facilitate the accurate assembly of the various pieces of wood from which the transverse frame of the boat is constructed.
According to this invention, the jig comprises a base-plate large enough to accommodate the largest transverse frame, a plurality of sets of differently shaped guides, one set for each frame, and each set having a number of guides, one vguide for engaging each pair of adjoining members of a frame, each of which guides comprises a base adapted to rest on the base-plate and provided with at least two upstanding abutments adapted to engage respectively the outer faces of two adjoining members and which base-plate is formed with a number of sets of anchorages, one set for each polygonal frame and each anchorage adapted fixedly to engage a base of a guide. Preferably, each guide is provided with a number of anchorage members projecting from its base and the base-plate is formed with a number of sets of anchorage holes, one set for each polygonal frame, and each set comprising a number of groups of holes, one group for each guide, each group having the same number of holes as the number of projecting anchorage members.
In order that the guides may locate gusset plates over the joints between each pair of adjacent members of the frame, the length of the upstanding abutment may be greater than the thickness of the frame above which they project and thus form locating members for said gusset plates.
According to another feature of this invention each guide member is provided with two or more dowel-pins and the plate has holes drilled in it in the appropriate position to locate each guide properly with respect to the other guides of its set.
In order to prevent error in assembling the various guides of a set, the dowel-holes are spaced differently for each frame, so that for any one guide there is only one set of holes which will receive its dowel-pins.
Preferably also all the lines of a boat are inscribed on the plate, and they may be marked with suitable identification marks and the guides are correspondingly marked.
One embodiment of the invention is illustrated in the accompanying drawings in which Figure 1 is a plan view of the jig, Figure 2 is a plan view on an enlarged scale of one of the guide plates and Figure 3 is an elevation of Figure 2 looking in the direction of the arrow indicated on Figure 2.
A jig according to the present invention is conveniently used on a large flat wooden table 4, and consists of a sheet of metal 5 somewhat larger than the over-all dimensions of the largest frame of a boat. The various guides consist of small flat plates 6, Figure 3, which are preferably made of metal and provided on their underside with two dowel-pins 1 received in holes H in the plate'and in the table 4, and these plates are located by their dowel-pins at such positions I on the plate5 as correspond to the joints of a transverse frame of the boat as is shown in Figure 1, where they are located at the keel, chines and gunwales. The guide plates are each formed with an angle corresponding to the angle between I the adjacent frame members 9, and upstanding plates 8 are provided on the edges of each plate 6 to constitute abutments against which the frame members 9 can be located.
The frame members are cut to the proper dimensions and laid in place on a set of guides, and it is thereby ensured that they abut one another properly and at the correct angle. The gusset plates I 0 are then laid on top of the frame members, the plates 8 extending sufficiently above the frame-members to locate the gusset plates also, as is seen in Figure 3. The gusset plates are next screwed to the frame members, thereby completing the frame as a rigid structure while on the jig, from which it is then removed ready" for use.
The dowel-holes II are spaced differently for theplates of each frame as shown in Figure 1, so that for any one guide there is only one set of holes which will receive its dowel-pins.
The lines of the boat may be inscribed on the metal plate as an additional guide as shown in Figure 1, and it will be seen that, by the use of the differently spaced dowels, and the marking of the various sets of guides, that is to say their any of a number of different polygonal transverse frames of a boat, which jig comprises a base-plate large enough to accommodate the largest transverse frame, a plurality of sets of differently shaped guides, one set for each frame, and each set having a number of guides, one guide for engaging each pair of adjoining members of a frame, each of which guides comprises a base adapted to rest on the base-plate and provided with at least two upstanding abutments adapted to engage respectively the outer faces of two adjoining members and which base-plate is formed with a number of sets of anchorages, one
set for each polygonal frame and each anchorage adapted fixedly to engage a base of a guide.
2. A jig adapted to locate in correct angular relationship during assemblage the members of any of a number of different polygonal transverse frames of a boat, which jig comprises a baseplate large enough to accommodate the largest transverse frame, a plurality of sets of differentlyshaped guides, one set for each frame, and each set having a number of guides, one guide for engaging each pair of adjoining members of a frame, each of which guides comprises a base adapted to rest on the base-plate and provided with at least two upstanding abutments adapted to engage respectively the outer faces of two adjoining members and with a number of anchorage members projecting from its base and which base-plate is formed with a number of sets of anchorage holes, one set for each polygonal frame and each set comprising a number of groups of holes as the number of projecting anchorage members on the base of the guide, which holes are adapted rigidly to engage those anchorage members.

A jig adapted to locate in correct angular relationship during assemblage the members of any of a number of different polygonal transverse frames of a boat and to locate gusset plates over the joints between each pair of adjacent members, which jig comprises a base-plate large enough to accommodate the largest transverse frame, a plurality of sets of differently-shaped guides, one set for each frame, and each set having a number of guides, one guide for engaging each pair of adjoining members of a frame, each of which guides comprises a base adapted to rest on the base-plate and provided with at least two upstanding abutments of a length greater than the thickness of the frame members and adapted to engage respectively the outer faces of two adjoining members near the joint between them and to locate a gusset plate to be secured to them over said joint and which base-plate is formed with a number of sets of anchorages, one set for each polygonal frame and each anchorage adapted fixedly to engage a base of a guide.
4. A jig adapted to locate in correct angular relationship during assemblage the members of any of a number of different polygonal transverse frames of a boat, which jig comprises a base-plate large enough to accommodate the largest'transverse frame, a plurality of sets of differentlyshaped guides, one set for each frame, and each set having a number of guides, one guide for engaging each pair of adjoining members of a frame, each of which guides comprises a base adapted to rest on the base-plate and provided with at least two upstanding abutments adapted to engage respectively the outer faces of two adjoining members and with a pair of dowel pins projecting from its base, which base-plate is formed with a number of sets of holes, one set for each frame and each set comprising a number of pairs of holes, each of which pairs of holes is arranged to receive a pair of dowel pins on the base of a guide,
