7 Claims.

to gussets and particugussets or gussets for reinstructures and it has for provide a gusset that shall be adjustable or extensible to flt walls of various angular relations.

As particularly well exemplified by boat hulls, the side and bottom walls thereof may have various angular relations in the same or different boats.

Thus, whenever, a

gusset is employed along the hull, its sides, co-operating with the side and bottom of the b oat, must conform in angular relation to the particular angular relation of the side and bottom walls of the boat at the position of the gusset. So far as we are aware, this situation has heretofore been met by providing separate gussets for each wall angle, or

it may have been makeshift structures.

To simplify, ture and to provide a ture that may met by various compromise or eccnomize and facilitate manufacsimple single gusset strucbe employed between walls of any practical angle, we provide a gusset including side-by-side engaging web parts which so overlap as to remain in overlapping relation within a practical range of angle sides. vide adequate adjustment of the wall or These sides, in any relation, prooverlapping area for laterally spot welding the same together.

An extension of sion of flanges on brace side of the web the idea includes the provithe hypothenuse or angleplates, which flanges also overlap for spot welding to each other and to a brace extending transve rsely between the webs.

Fig. 1 of the accompanying drawings, shows a transverse or cross section of a portion of a boat or pontoon, at the meeting of a side wall and the bottom wall' thereof,

our invention, in side Fig. 2 is a view similar side and bottom walls of angles and the gusset new angle,

Fig. 3 shows the perspective,

together with a gusset of elevation.

to Fig. 1 showing the the boat at different of Fig. 1, adjusted to the gusset parts separated and in Fig. 4 is a perspective view, showing the parts of Figs. 1, 2 and 3 form of to better advantage, and Fig. 5 is a View, similar the invention.

to Fig. 4, of a modified Referring to Figs. 1 to 4, inclusive, the parts being preferably constructed of sheet metal, comprise a side wall 2, a edge stringer 5 of stringers 6 of channe bottom wall 3, a longitudinal Z-section, longitudinal side l section, longitudinal botvabout the then common tom stringers 7 of channel section, and a transverse frame of box section.

The transverse frame comprises transverse'andv upright channel sections 9 and 10 that are mounted on the stringers 6 and 7 and cover plates 11 60 and 12 respectively. A

The transverse frame is braced by small gussets 14, not of the present invention, in the side stringers 6, gussets15, in the bottom stringers 7 and angle pieces 17 between the frame and the 65 side 2.

The gusset of the invention comprises halfportions including angle-brace or web portions 20 and 21 that are preferably constructed as segments of a disc having transverse flanges 22 and 7p 23 along the arcuate edges thereof and transverse flanges 24 and 25 along the remote or furthermost radial edges thereof: l

The half portions are constructed to so interilt that the web portions 20 and 21 are in side by side 75 engagement and one of the flange portions 22 and 23 overlies the other in engagement therewith.

The half portions are shown, in Fig. 3, in position just before they are brought together to place the apices 27 thereof in substantially coincident 80 relation and to interflt the Webs 20 and 21 and the flanges 22 and 23 for sliding parallel movement apex 27.`

With the halves thus brought together, they are placed in position, as indicated in Fig. 1, and adjusted along the web or brace section of the composite gusset until the flanges 24 and 25 conform to the sides of the angle between the walls 3 and 2 against the covers 11 and 12 of the transverse box frame to which they are spot welded. In this position, the webs 20 and 21 are preferably spot welded, as indicated at position 29, and the overlapping portion of the flanges 22 and 23 may 4 be similarly welded.

A plate 30 may then be cut to proper length 95 and placed along the flanges 22 and 23, between the remote ends thereof and across theoverlap.

Fig. 2, differs from Fig. 1 only in the degree of the angle between the side and bottom walls 2 and 3, showing the gusset adjusted to this increased angle, with the webs and flanges still overlapping and the plate 30 of increased arcuate. dimension.

As indicated in Fig. 4, there are twogussets, as r above described, disposed in laterally-spaced rela- 10 tion, with the plate 30 functioning as. a lateral brace or as a cover to render the resultant or composite gusset of box-like character.

In the form of the invention, illustrated in Fig. 5, in which corresponding parts are designatedl 11C by corresponding reference characters, the structure is substantially the same as that of Fig. 4, with the exception that the yplate 30 and the flanges 22 and 23 are omitted to render the structure of lessstrength but to obtain the advantages of reduced weight and cost in service where the stronger and heavier gusset is not required.

The device is also particularly adapted to facilitate the joinder of its parts by spot welding which is the attaching means of probably the simplest, mostl economical and best formA in the metal joining art.

While we have shown and described particular forms of the invention, changes may be effected therein, without departing from the spirit and scope thereof, as set forth in the appended claims.

We claim as our invention:

1. A gusset of substantially box-section including parts adaptedjor adjustably fitting the gusset between walls of various angular relations to each other.

2. A gusset comprising an angle brace including members having pivotal portions for turning movement in the direction of the brace to adjustably fit the gusset between Walls of various angular relations to each other and to have said portions overlapping in theV direction of the brace in any adjusted position.

3. A gusset comprising an angle brace including portions for movement in the direction of the brace to adjustably fit the gusset between walls of various angular relations to each other and to have said portions overlapping in the direction of the brace in any adjusted position, said portions also having transverse flanges for overlapping relation in said direction in any -adjusted position.

4. A gusset comprising an angle brace includthe brace to adjustably nt the gusset between walls of various angular relations to each other and to have said portions overlapping in the direction of the brace in any adjusted position, said portions also having transverse flanges for overlapping relation in said direction in any ad- -justed position, and a member for connecting attachment between s'aid fianges.

5. A gusset comprising ing a pair of sheet members substantially in the form of disc segments and adapted for parallel movement in adjacent overlapping side-by-side engagement about a center at the intersection of the radial edges thereof to adjust the angle between the remote radial edges thereof and to be secured together in adjusted position.

6. A gusset comprising a pair of laterallyspaced web portions each including a pair of sheet members substantially in the form of disc segments and adapted for parallel movement in adjacent overlapping side-by-side engagement about a center at the edges thereof to adjust the angle between the remote radial edges thereof and to be secured together in adjusting position, and a plate for extension transversely between and along the arcuate edges of said web portions across said overlap.

7. In combination, ous angular relation therealong, of gussets extending between, the walls at spaced positions therealong, said gussets having substantially identical adjustablyrelated parts adjusted to fit the gussets to the walls in accordance with the particular angular relation of the walls at the positions of the several gussets.
