- PLANER FOR BOATS Filed March 7, 1955 3 Sheets-Sheet 5 INVENTOR EDWARD O.THOMPSON ATTORNEYS ite St tes Patent PLANER FOR BOATS I Edward 0. Thompson, Peshtigo, Wis.

Application March 7, 1955, Serial No. 492,650 8 Claims. (Cl. 144 144 This invention appertainsbroadly to joinery and more particularly to a novel means for facilitating the accurate .fashioning of planks and the like for the building of boats and other structures.

Owing to the longitudinal curvature of a boat from bow to stern, and the transverse curvature from gunwale to keel, much difliculty is experienced in the fitting of planking to the hull and this condition is aggravated where the planking overlaps, as in clinker built boats. Thus the longitudinal edge of the planking which is overlapped by the next adjacent piece of planking must be beveled on a compound curved to correspond to the longitudinal and transverse curvature of the boat. Obviously, this requires the skill of an expert artisan.

It is, therefore, one of the primary objects of my invention to provide a novel rotary plane for use in combination with a jig and a template for the plank or work, the plane being constructed in such a manner that the same is accurately guided by the jig and template to give the plank or work the desired bevel by the mere sliding of the plane back and forth by an operator.

Another salient object of my invention is the provision of means whereby templates of different charactersfor different boat planks can be readily associated with the A further important object of my invention is the provision of a rotary plane having a supporting guide associated therewith for movementin a longitudinal guide track forming a part of the jig and located adjacent to the table for the plank or work, the plane being mounted for universal movement on the supporting guide, the plane also having a guideshoe arranged in spaced relation to the supporting guide for travellingmovement over the template, the guideshoe functioning to tilt the plane on the supporting guide during the slidingmovement of the plane along the jig and over the plank or work.

Another further important object of my invention is the provision of a novel supporting guide for'the rotary plane for sliding movement over'thework and along the guide track, the plane being mounted for rocking movement up and down on the supporting guide and around anaxis parallel to the longitudinal axis of the rotary plane, whereby theplane can be tilted in the desired directions by the guideshoe as the same travels over the varying curvature of the template.

A still further object of my invention is the provision of means for initially adjusting the rotary'plane 'on its supporting guide to regulate the depth of cut of the knives.

A still further object of my invention is to provide a novel rotary plane for beveling the edges of planks and the like of the above character, which will be durable and efficient in use, one that will be simple and easyto manufacture and one which can be manipulated .by nonskilled workmen. I i

With these and othenobjects in view,,th,e invention consis'ts in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described and claimed and illustrated in the accompanying drawings, in which drawings,

Figure 1 is a transverse sectional view through the jig and its template showing the rotary planer in position for beveling a plank, the plane being also shown in transverse section;

Figure 2 is a side elevational view of the jig with a template in place and a plank supported on the table of the jig with one longitudinal edge thereof beveled in accordance with the formation of the template;

Figure 3 is a side elevational view of my novel rotary plane, parts of the view being shown broken away and in section;

Figure 4 is a top plan view of the improved plane;

Figure 5 is an elevational view of the plane showing the opposite side thereof from Figure 3;

Figure 6 is an enlarged detail fragmentary transverse,

sectional view taken on the line 6--6 of Figure 3, looking in the direction of the arrows and illustrating'the connection of one end of the supporting guide with the plane;

Figure 7 is an enlarged fragmentary detail transverse sectional view taken on the line 77 of Figure 3, looking in the direction of the arrows, illustrating the adjustable connection of the plane with the other end of the supporting guide;

Figure 8 is an enlarged fragmentary horizontal sectional view taken on the line 88 of Figure 3, looking in the direction of the arrows, illustrating a part of the adjustable connection in detail, and

Figure 9 is an enlarged fragmentary detail transverse sectional view illustrating the connection of the guide" arms with the guide supporting bracket.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views,the letter P generally indicates my improved rotary planer for use in conjunction with a jig J for operating on a piece of work W.

The jig J comprises a base 10 and this base preferably includes a base plate 11 having secured thereto spaced parallel longitudinally extending supporting

walls

12 and 13 for a table 14. The work W is placed upon the table 14 so that one longitudinal edge thereof is substantially flush with the wall 13, as best shown in Figure l. The wall 13 not only forms a support for the table, but also functions as a guide for the rotary planer P and consequently, this wall has secured thereto a longitudinally extending guide track 15 and this track extends the entire length of the wall 13. The track is so fashioned as to form in conjunction with the Wall 13 a'longitudinally extending guide slot 16, which opens out through the upper.

end of the jig. It is to be noted that the guide track 15 terminates slightly below the upper surface of the table 14. 7

By referring to Figure 1, it can be seen that the base plate 11 of the jig extends forwardly of the wall 13 and detachably associated with the forward edge of the base plate 11 in spaced relation to the wall 13 is a template 17. I

Now considering that the work W is a plank of a boat and that one longitudinal edge of the plank is to be beveled on a compound curve, so as to conform to the longitudinal and transverse curvature of a boat, then the template 17 has its upper edge 18 fashioned to agree exactly with the bevel to be placed on the piece of work W. A template 17 is provided for each plank of a boat.

Now referring to my improved rotary planer P,. the

same includes a casing 20'having rotatably mounted therein and extending transversely thereof a cylinder 21 can be rapidly rotated when an electric circuit is closed through the r'n'ot'oi 23. Any desired means can be pm: vided for driving the cylinder 21 from themotor, but as illustratedthe armature shaftof the motor has secured thereto a sprocket 24" and the shaft for the cylinder has secured thereto a spr'o'cket 25'. A sprocket chain 26 is trained over the sprockets 24 and 25.- A guard 27 is rigidly secured to the base 20' for the sprockets and-the sprocket chain. p provided for manipulating the planer and the planer provided with other adjuncts, such 'asa laterally extend ing hood 29 for the wood being planed. The parts of the planer, jtist described are common in rotary planers now on the market, and hence, these parts have not been describediri detail, and the invention resides in novel means associated with the base of the planer so that the planer can be associated withthe jig J and guide forthe jigand the template for giving the desired and correct bevel to the longitudinal edge of the work W.

Referring to theimprovements on the planer, the same embody a guideshoe 30 for traveling movement over the edge 18 of the template .17. The shoe 30 preferably includes a block 31 having a polished lower face for en gaging the edge 18 of the template and this block is removably secured by a bolt 32 or the like to a bracket 33 and this bracket is in turn rigidly bolted to the guard 27. The opposite end of the frame or casing of the rotary planer P has associated therewith, in a novel manner, guide brackets 34 which cooperate with the work W, and the guide track 15. The guide brackets 34 are of an angle shape in side elevation and are arranged in A suitable manipulating handle 28 is spaced relation to one another aridare rigidly fastened to a Iongitudinallyextending supporting bar 35. Each bracket 34 includes an upper arm 36, which slides over the upper face of the work and 21 depending right angularly extending arm 37, which slidably seats in the guide track, i. e., the slot 16. In order that the planer P will have universal movement relative to the brackets 34, a novel connection is bad between the planer and said brackets 34 and theircross bar 35, and this connection consistsof the following: One ,side of the base or frame 20 of the planer P around the shaft of the cylinder 21 is 39 is provided at its opposite sides with laterally extend ing arms42 and 43. The arm 42 is connected by a hinge 44 with the bar and it is to be noted that this hinge 44 includes a leaf '45, which is riveted or otherwise secured to the bar and a leaf 46 which is connected to the arm 42 by a pivot 47; Thus, the arm 42 and consequently the plane itself can swing up and down on the bar 35 and also rockon the pivot 47.

The arm 43 is connected to the bar 35 by means of a hinge 48 and this hinge includes a leaf 49 which is riveted or otherwise secured to the bar 35 and a leaf 50 which is adjustably connected to the arm 43. Theconnection of the arm 43 with the leaf 50 is best shown in Figures 7 and 8 of the drawings. As illustrated, the arm 43 rotatably carries an adjusting screw 51which is threaded in a'traveling block 52. This blockin turn is rigidly fastened to the leaf 50 by a screw 53 or thelike. The traveling block has formed thereon laterally extending cars 54 which snugly engage a part of the arm 43 and these cars form guides for the block during the adjustment thereof. By turning the screw 51,the plane can be swung on the pivot 47 so that the cylinder 21 and its.

1 4- A knives 22 can be adjusted relative to the work without the necessity of adjusting the knives in the cylinder.

In operation, the desired template 17 is secured to the jig and the work W is laid on the table 14 with one longitudinal edge thereof flush with the vertical face of the wall13. The work can be temporarily secured to the table in any desired way. The plane P is now placed in position on the jig, with the guide brackets 34 so placed that the arms 37 will slide freely in the guide slot 16. The horizontal arms 36 of the guide brackets engage the top surface of the work and the guideshoe 31 is rested on the edge 18 of the template. The plane P can now be slide back andforth over the work to bevel the longitudinal edge thereof and as the plane travels over the work with the shoe following the contour of the edge 18, of the template 17, the plane will rock on the

hinges

44 and 48 and will turn in the ring 39. Thus, the plane will follow the exact curvature of the edge 18 of the template and bevel the longitudinal edge of the work in exact accordance with the form of the template. Obviously, the plane is carried by. the brackets 34 for universal movement and while I preferably use the ring 19 to permit turning of the plane on the. brackets, it is to be understood that other types of pivots can be utilized to connect the brackets with the plane.
