25 Claims.
This invention relates to boat assembly jigs and more particularly to a mechanism by which the various pre-fabricated units of a metal boat hull may be located and held, with r spect to each other in proper position to be assembled together, and to move these parts during the assembly thereof into various positions to facilitate such assembly and the securing of them together.
In the manufacture of metallic boats various parts, such as decks, bottoms, etc., are fabricated previous to the assembly of the complete boat hull and are then brought together and assembled to each other. It is therefore desirable that mechanism be provided to properly support these prefabricated parts in position relative to each other before they are fastened together. It is also desirable that, as parts are added to the boat hull being assembled, provision be made in the structure of the mechanism to revolve the part, or parts, already assembled together into accessible position to permit efiicient assembly of other parts thereto. It is the principal object of this invention to provide an improved mechanism for accomplishing the above desideratum.
Another object of this invention is to provide an assembly jig having improved means for bolding the various prefabricated parts of a metallic, or like, boat hull, which may be readily raised and lowered, and revolved as desired during the assembly of the parts.
Still another object is to provide in an assembly jig of the above nature improved means to raise, lower, and revolve the boat hull unit, or units, holding means.
A further object is to provide in an assembly jig for boat hulls improved means to locate and hold accessories in position to be attached to the boat hull being assembled.
A still further object is to provide an improved assembly jig for metallic, or like, boat hulls which will be relatively inexpensive to manufacture, simple in construction, compact, and very eflicient, safe, and durable in use.
With the above and other objects in View which will appear as the description proceeds, there has been illustrated in the accompanying drawings a boat hull assembling jig in which the features and principles of this invention may be conveniently and practically embodied.

Referring now to the drawings wherein like reference numerals designate like parts throughout the several views the reference numeral [5 denotes (see Figures 11, 12, 13, and 14) the upper forward deck of a metallic boat hull which preferably is prefabricated into a unit by assembling together its component parts such as preformed top plates, beams, etc. A preformed rear deck it is also prefabricated by assembling its parts together into a unit. Side decks IT and [8 as units, side plates i9 and 2!, and a shaft supporting strut 2!! are preformed as units ready for assembly. The boat bottom 22 is pre-fabricated into a unit from preformed plates 23 and 24, floor bottom and engine bed beams 25, keel bars 26 and 21, shaft log 23, etc. A transom plate 29 is preformed as a unit ready for assembly. These various units are then properly located one at a time in position on the assembly jig of this invention and secured together to form a complete boat hull.
The boat hull assembly jig of this invention includes a base frame comprising base side beams 3| and 32 extending lengthwise, base end beams 33 and 34 extending crosswise adjacent the ends of the side beams 3| and 32, and vertical beams, or risers 35, 36, 3'1, and 38 extending upwardly from each of the jointures of the side and cross beams 3t, 33; 3!, 3d; 32, 33; and 32, 3t. Suitable bracing beams 39 and it! are provided to support and brace each of the vertical beams 35, 36, 31 and At one end of the base frame, which will be hereinafter termed the front end, the cross beam 34 is interrupted intermediate its ends (see Figure a) to permit removal of a completely assembled boat hull from the jig onto a cradle (not shown) but which rolls on tracks ll and G2. lhe base frame is suitably anchored to concrete piles as indicated in Figures 1, 3 and 4.
A boat hull supporting carriage is disposed between the frame uprights 35, 3t, 31, and 38 and comprises lengthwise side beams a3 and M and end cross beams and Z6 suitably reinforced by diagonally disposed beams ll (see Figure 2) and a strut counter-balancing cage composed of angularly disposed beams and bars 48 anddil tied together at their outer ends by lengthwise bars 56. The carriage has a rectangular vertically disposed end frame at each end of the beams 43 and Mi, the bottom members of which are constituted by the end cross beams 45 and' lfi, and
having vertical side beams 55, 52 and 53, 5% each pair being tied together at their upper ends by cross beams 55 and 56 respectively. The bracing beams l? tie the end frames to the lengthwise beams lfi and M. The vertically disposed end framecomposed of'beams' 4%,53, 5:2 and 56 is disposed at the front end of the base frame and the other end frame composed of beams 45, 5|, 52 and 5b is disposed at the rear end of the base frame.
A pluralityof vertically disposed plates 58 extend'across the carriage frame'from one lengthwise beam (3 to the other 4%, the first being spaced rearwardly from the forward end frame, and the others being spaced apart along the carriage, The plates locate and support the forward deck unit 35, as indicated in dotted lines in Figure l, the upper edge of each being formed to substantially fit the surface contour of said deck "15 which is clamped at its rear edge to a cross bartfi by aplurality of C clamps 8|. At 'andalong each side lengthwise beam'4l3and 44 'is a spaced apart series of short platesfiiZ and 63 respectively, each extending inwardly and formed on its upper edge to conform to the contour of the side'decks '5"! and it respectively. The plates 62 and'fit'are supported'from the lengthwise side beamsfilt and i i-byuprights Ed. The outer edges of 'the forward'deck ib'and of the side decks H and it rest on rails'flii and St,'one at each side of the carriage, and which 'a'rebent to the "desired contour'of the side of the boat hull and of these units'as they'are preformed before assembly. The rear deck unit it is supported on lengthwise'extending bars 6i in turn supported fromthe lengthwise side framebeams l3 and M, on a' cross beam'GB held up by vertical beams 69, and by a cross beam ll secured to and'extendingbetween a pair of vertically disposed uprights l2 and "i3 ofa hull supporting frameand which are spaced forwardly from the vertical side'beams ill, "and are disposed between the rails 65 and 66. The bars'iil are of different heights to conform crosswise with the contour of the rear deck !6, and support a cross bar it disposed to have the outer rear edge of the rear deck it seat thereon. Two or more of the bars 6'5 are made longer than the others and have an upright extension on their outer ends spaced from the rear end of the rear deck l8 whereby wedges l5 may be inserted to'securely clamp the lower edge of the transom plate unit 29 against the adjacent edge of the rear deck 96.
The hull supporting frame, including the pair of uprights and it at the rear end thereof, has a pair of uprights l3 and ii at its front end 4 and a pair of uprights l8 and 19 intermediate its ends. These uprights extend upwardly from cross beams 8i secured to and extending between the lengthwise side beams 43 and .4. Preferably the uprights l2, T3 are disposed, in relation to the aft deck it, just forward of its forward edge, and the uprights l6, '5? are disposed, in relation to the forward deck it, just to the rear of its rear edge. The uprights of each pair are spaced apart laterally to a maximum amount while permitting them to be withdrawn, from the assembled boat hull, between the side decks l? and I8, and the end pairs of uprights are so disposed that they may be readily withdrawn, from the assembled boat hull, between the front and rear decks, l5 and it. The upper ends of the uprights l2, l8 and it are tied together by, and support, a lengthwise beam 82, and the uprights l3, l1 and is are tied together by and support a lengthwise beam 83. A plurality of lengthwise spaced apart cross beams 8G reston, extend between, andare secured'to the lengthwise beams 82 and'tis in positionto have the boat hull bottom, floor and engine bed beams 25 seat upon their upper surfaces, the cross beams 84 being of proper'height at each boat beam to properly support the-bottom unit 22'of the boat hull. A plurality of turnbuckies 85, detachably secured to the lengthwise beams 82 and 83 and to selected ones of the boat hull beams 25 are used to clamp the boat hull unit 22 tightly down upon the cross beams at.
A vertically disposed lengthwise extending bar 86 extends'between the uprights l3, T! and l8, '49 above the cross beamst l and is formed along its upper edge to engage and support the boat hull bottom 22 at the joint'ure between the plates 23 and 24. Posts ill and 38 laterally spaced apart and extending-upwardly from the cross beam 84 at the uprightslfi and'lil are engaged by the hull beam 25 at these points to locate and support the hull bottom. Similar posts as and SI are supported on the'cross beam 8d at the uprights i6 and Ti, and on a cross beam 92 extending across the frame from the side beams 82 and 83. The bar 86 is tiedto the respective cross beams byposts 83 and to the cross beam 92 by plates 84. Inasmuch as the uprights l2, l3 and it, H and 79, it are permanently secured to the carriage by being welded to the cross bars'8l, which, in turn are welded to the lengthwise carriage beams 43 and M, the hull supporting frame, formed as described above may be termed as being integral with said carriage. Vertically spaced and lengthwise extending rods Q5 and 95 formed to fit the contour of the boat hull sides i9 and 2! where they engage the same, to locate and support the same during'the assembly of the hull, are hingedly "supported from laterally spaced apart uprights bl, see Figures 1 and 2, disposed intermediate the uprights '12, 3 and '!8, 'lil, from the uprights l3 and "19, and from the uprights i6, 77, by being pivoted to bars 9? extending outwardly from each'of said uprights. The rods 95 and t'locate the side plates is and 2! and are arranged to be swung'upwardly out of the way to permit the completed boat hull to be removed from the'hull supporting frame.
Provision is made to locate and support the boat hull at its front end by means of a curved beam 98formed to fit the bow of the boat hull. The beam 93 -is"detachably secured to the hull supporting frame at the foremost cross plates 58 by bolts 99 and at its upper end to a supporting plate it]! by bolts 562. One of the cross beams of the boat, hull restslonlthe plate II'II whichis mounted on and secured to a post I03 secured to and extending upwardlysthrough. the carriage from the frame work thereof; A detachable tie rod I04 is provided to reinforce the curved beam 98. Side bars Hi5 and I85 are detachablysecured at their front ends to the post I93 by means of a bracket III'I mounted on the post I63. The rear ends of the bars m5 and I06 are detachablysecured to the front end of the hull supporting frame at the uprights I6 and II by brackets I88. The outer edge of each bar I05 and I06 is formed to fit the contour of the side plates I9 and 2i respectively to locate and support the same in position during the assembly of the boat hull; Means to properly locate theshaft supporting strut 20 (see Figure 10) is provided and comprises a frame work I09 of plates and beams secured to and extending upwardly from the end cross beam 55. A rod end support III is supported by the frame Work I09 to locate and support a rod II 2 which is threaded through the shaft bearing lug H3 of the strut and into and through the bearing lug III of the shaft log 28. Suitable bushings II5 and I It are provided on the rod II2 to locate the bearing lugs I I3 and I It respectively, and to hold these lugs in alignment while the strut 20 is secured to the hull bottom 22.
Mechanism is provided to raise and lower and also revolve the boat hull carriage to facilitate the assembly of the various hull units. This mechanism is best shown in Figures 3, 5, and 6 of the drawings and includes a vertically disposed rectangular frame work at each end of the carriage each of which comprises horizontal upper and lower beams III and H8 and side beams H9 and I2I with suitable corner brace plates I22. The frame work at each end of the carriage is in lateral alignment with the frame risers 35, 36 and 31, 38 at the respective ends of the main frame. The risers 35, 36, 31, and 38 are preferably I beams with the grooved edge of the risers of each pair in aligned opposition whereby to form vertical guides for the side beams IIS and I2I of each frame work. Brackets I23 secured to and at each corner of each frame work upon the side beams I It and I H extend into the groove of the adjacent riser. Each bracket I23 supports and carries a pair of rollers I25 and I25. The roller. I24 is journaled to the bracket I23 to extend beyond the same and engage the central wall I26 of the adjacent riser and the roller I25 is journaled to the bracket I23 to extend beyond each side thereof to engage the side walls I27 and I 28 thereof (see Figure 6) whereby the frame work will be smoothly guided in any vertical movement along the risers. An electric solenoid operated catch I29 (see Figure l) is provided on each side of each frame work to automatically engage any one of a series of teeth I 3! provided in the edge of the side wall I23 of each riser to prevent the carriage dropping inadvertently during raising and lowering it.
Each end framework has bearing plates I32 extending inwardly from the horizontal beams III and I I8 to support rollers I33. Spaced apart circular plates are suitably secured together to form a large roller I34 to ride on the rollers I33. In this instance four rollers I33 are provided spaced about each of the peripheries of the rollers I34. The rollers I34 are secured to the adjacent end frames of the carriage by spaced apart beams I35 and I36, which are secured to and extend be-- tween the horizontal beams 45, 55, and 46, I56, and to the inner plate of each of the rollers I3 5. By
this constructionlthe hull supportingcarriage is supported and carried'by. the frame work at each end, which is vertically movable up and down the risers, and may revolveinrespectto the main frame. by means of .the large :rollers I34 riding on the rollers I33. supported on the ad jacent end frame work, the rollers. I 33 having end flanges I38 adapted to prevent lengthwise movement of the carriage by straddling the edge of the large roller I35.
The carriage carrying frame-works are arranged to beraised and lowered along-the risers of the main frame by an electric motor I- (see Figures 1, 2, and 3), which, through a gear reduction in housing I36; is arranged to rotate a shaft I3Iextending the length of and along one side; of the main frame being journaled at intervals in bearings I38. Secured on the front and rear ends of and rotating with the shaft I3! is av pair of cable drums I39, I II' and I42, I43 respectively. A cable IM leads from thedrum I39to and-over a pulley I45 journaled at the upper end of the riser tlI, and a cable I 16 leads from the drum I42 to and over a pulley I4'I journaled at the upper end of the riser 35. A cable Hit leads from the-drum ItI'downwardly over idler rollers M9, I5I, and I52 (see Figures 2 and 4) to and over a pulley I53 journaled at the upper end of the riser 38 and a cable I M leads from the drum M33 across the main frame and over an idler roller I55 to and over a pulley I 56 journaled at the upper end of the riser 36. From the respective pulleys I 15, I ll, I53,-and I56 the respective cables lead downwardly to and; over pulleys I57, one of which is secured by a bracket I58 to eaclrof the upper corners of each end frame work and then upwardly to be fastened to the adjacent riser at I59. Proper actuation of the motor I35 will wind up the cables on their respective drums to raise the end frame-works and through the connection of the large rollers at each end with the boat hull carriage will raise the carriage and the boat hull parts and units thereon to any desired height and by reverse operation permit the same to lower.
An electric reversible motor IBI (see Figures 1, 2, 3, 5, and 6) through a gear reduction in casing I62 drives a gear I63 by means of a chain belt I64. The gear I63 is secured on a shaft I65 having a toothed disc, or pinion, I56 secured thereon to mesh with spaced apart pins It? extending between the plates forming the large roller I34 at the rear framework adjacent the rear end of the main frame. The shaft I65 is journaled in a bracket IGII secured to and extending downwardly from the upper beam II'I of the rear end framework. As shown the motor I6I and the gear reduction housing are Assuming that a completed boat hull has-just beenremoved from the assembly jig, embodying the features of this invention, the hull support-- ing carriage will be in a position opposite that shown in Figure 1. That is, the carriage will be up-side down from the showing in Figure l in order to permit the removal of the boat hull from the hull supporting frame onto a cradle (not shown) which was previously disposed in under the carriage on the tracks AI and M (see :Figures 2 and 4) to receive the boat hull and'facilitate it being withdrawn from in under the carriage. After a boat hull has been removed the carriage is revolved 180 degrees by operation of the motor I6I and then lowered by operation of the motor I35 to dispose it in the'position shown in Figure 1. It is, of course, to be understood that in order to have removed the completed hull from the carriage the shaft bearing aligning rod III and bushings H5 and H6 were removed, the side plate locating and supporting bars 95 and 96 were swung upwardly and fastened, the side plate locating and supporting bars I05 and I06 were removed, and the curved bow supporting beam 98 was removed.
Having positioned the carriage as shown in Figure 1, the side plate bars 95 and 96 are lowered into position and fastened. The forward deck unit I5 is now placed and clamped on cross plates 58, the rear deck unit I6 is positioned and clamped on the lengthwise bars 61 and its rear edge rests on the cross bar I4. The side decks I! and I8 are placed and clamped on the bars 62 and 63 respectively and their outer edges with the outer side edges of the forward deck I5 line up with and rest on the side bars 65'and 66. The side bars I05 and I06 are now positioned and secured on the post I03 and uprights, and the curved beam 98 is attached to the post I03 and the carriage frame. The joints between the forward deck I5 and the side decks I1 and I8 are now tack-welded together along the lines I72 and H3 (see Figure 14), and joints between the rear deck and the side decks are tack-welded along the lines I14 and I15.
The bottom unit 22 is now laid in position onto the hull supporting frame and the post and curved beam I03 and 98 respectively and the transom plate unit 29 is positioned in place between the rear deck unit I6 and the bottom unit 22. The bottom unit 22 and the transom plate unit are now clamped in place and tack-welded together along the line of jointure I16 (see Figure 13). The transom plate and the rear deck are tack-welded along .the line of jointure 51 11.
The carriage is now revolvedrninety degrees to present one of its sides uppermost by operation of the motor IBI, A side plate unit, for instance I9is laid in place upon the frame and itsedges at their jointure with the edges of the forward deck I5, transom plate 29, rear deck I6, side decks, and bottom unit'22 are tack-welded. The carriage is then revolved'one hundred and'eighty degrees and the other side ,plate unit is secured to the bottom unit, decks, and transom "plate. The carriage is thenrevolved back ninety degrees to the position shown in the drawings w-hereat the welding is completed around the edge of the bottom unit 22, and the strut 26 :is assembled thereto by the use of the lccatingbar III and bushings H5 and H6. After =completion of the above operations the-curved forward beam 98 and the side bars I05 and =I06 are :removed, the side supporting bars are swung upwardly and fastened, thestrut locating rod III and bushings H5 and H6 are removed, and the carriage is raisedby operation of the-motor I35, revolved by operation of the motor "I6'I one hundred and eighty degrees, and then lowered to lay the completely assembledboat hull upon a cradle to be rolled out from under the carriage.
In the mechanism above described, the boat hull is assembled by positioning its various prefabricated units on a locating and supporting rcarriage. The carriage is rotatively mounted on, and :supported by, end slides, or frames, by means of a large roller I34 secured to the carriage, and the rollers I33, the latter being secured to the end slides. The slides, or end lframes, carrying the rollers I33 are adapted to smoothly slide between opposing pairs of vertical risers to raise or lower the carriage under control of the motor I35. The combination and association of the various novel features in the structure of the boat hull assembling jig illustrated provides a mechanism whereby prefabricated and/or pre-formed boat hull units may be practically, rapidly, and efficiently assembled together to form a true shaped, sturdy and serviceable boat hull with a minimum expenditure of labor and time.
While there has :been shown and described herein a boat hull assembling jig in which the features and principles of this invention may be embodied in practice, and for a particular style andform of boat hull, it will be understood that the same'may be embodied in other specific forms and for other styles and forms of boat hulls without departing from the spirit and essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention.
