.Dl lication January 22, 1930, Serial No. 422,598 Renewed July 10, 1933 i a i 6 Claims,

It is very often necessary to'shape planks or strips to conform to the varying contour of the ships hull, or to conform to varying angles. In order to accomplish such work, it is essential to provide the templet with a groove or a batten so that when the groove is engaged by a templet guide, a plank may be provided with varying curvatures and angles simultaneously with the shaping of the planks. 7

It is therefore the purpose of the present invention to provide an improved shaper including a motor supporting guide, the guide adapted to vary in position, according to the angular position of the motor, a cutter being carried by the motor shaft and adapted to vary in its position according to the angular position of the motor, so as to correspond with the angular position of the guide, thereby enabling the plank or strip or similar article to be shaped as may be desired in order to fulfill the construction of work at hand.

Another purpose is to provide, in a shaper of this character a templet so operable as to groove the plank or strip at the same time the planks edge is being shaped, the walls of the groove being capable of varying angularly relative to the shaped angle of the edge of the plank or strip.

Another purpose is to provide, in an apparatus of this kind, improved means, preferably of an electrical nature, though not necessarily, for actuating the templet, that is so operating it as to cause it to vary the groove being cut, in the direction of a curvature relative to the shaped edge of the plank or strip.

A further purpose is to embody, in a machine of the present nature, a gravity supported roller for cooperation with the plank or strip or other work to hold it in its guided position, there being tensioning means manually operated, whereby the pressure of the roller may be increased or decreased.

It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawings and claimed.

Figure 13 is a vertical sectional view on line 13-13 of Figure 11.

Figure 14 is a longitudinal sectional view on the line 14-'14 of Figure 'l.

Referring to the drawings, 1 identifies a frame which comprises segmental pieces, in which guides in the form of channels 32 are formed. These guides or channels 32 receive the feet 4a of the motor supports 4, which in turn support the motor 2, the motor shaft 2a. of which carries a revolving cutter 3.

On a screw 10 mounted in bearings 14 of the frame is a worm 11, which meshes with a worm gear 5, better shown in Figure 1 of the drawings, the worm gear 5 being in turn mounted on the shaft 31. The shaft 31 also carries two gears 6, which mesh with teeth 10a of a segment 4!) from which the supports 4 extend. This segment with its teeth operate in the guides 32. Obviously when the shaft31 rotates the gear 6 likewise rotatin movement is imparted to the segment, for the purpose of adjusting the motor into different positions, and thereby dispose the cutter in different angular relations with the plank or strip which is being shaped.

A worm gear 12 is also mounted upon a screw 10, and meshes with a worm 9 on the shaft section 9a, which is located in a housing 9b. Also mounted in the housing 9b are two motors '7, the

view on line 31, which in turn through the medium of the gears 6 will rotate the segments 4b in the opposite direction and thereby change the angle.

of the motor and the cutter 3.

A member 13, which may be called a nut, but which is more or less enlarged on one side and may constitute a contact element, is threaded on the screw 10.

Mounted on one side of the frame 1 are sprockets 19 and 20, and under the former of which a sprocket chain 21'passes. This sprocket chain 21 passes over the sprocket 20 and has attached to one cf'its ends a weight 22, the other end of the chain 21' is connected at 21a to one end of a quadrant 15, which is carried by a shaft 35. This quadrant or segment gear is designed to be operated by the chain. I

Spliced inthe chain 21 is a plate or connector 212' which has opposedproieoting lugs or

ears

21d and 21 which receive the contact screws 210, between the adjacent contact ends of which the contact element 13 operates, for closing an electric circuit over the wires or leads 26 and 27 with the electric'clutches 8', the circuit not being shown complete.

The shaft 35 which carries'the segment rack or quadrant also carries a gear 18,.which meshes with a gear'17, on a shaft 17a, which is mounted in bearings of the frame 1. A second gear 170 is also on the shaft 17a and. meshes with the rack teeth 17b on the under face of the templet guide 16, whichis mounted in a suitable guide groove 16a of the table 30. The rack 16 has an upstanding flange or protrusion 3011, which engages in'a groove 30b of the templet 28 on'which aplank, strip or other object 29'may" rest while its edge is being'shaped or formed.

Pivoted at 23a is an angle 1ne1nber'23, the short arm 23b of which has'anoteh 230, while the longer arm 23k has pivoted to it a hanger 23d. The hanger [is Lhshaped and depends in the direction of the plank or strip being operated on and supportsa roller 25, which bears upon the plank or strip to'hold it in position on the templet."

As shown in Figure 5 suitable insulation 33 is provided for the contact screws 21c.

A suitable guide 36. better shown in Figure 1 is provided for guiding templet 28.

The frame lcarries bearings 242 for. the recep-' tion of anadjusting screw 24, which is threaded in said bearings, and its end engagesin the notch 230. By adjusting this screw24-i'n one direction or the other, it may regulate the pressure of the angle member 23, namely to increase or decrease the pressure of the roller 25 on thework.

The work or object or piece 29 in Figure-7 partly constructed by the machine in Figures 1, 2 and 4 is formed with a beveled or inclined edge at 29c, the incline of which is reversed at its opposite ends, the inclines merging intermediately of the ends of the strip, and in constructing thisedge, the protrusion or projection or upturned flange 30a of the templet guide16 operates in the groove 28g of the templet 28, shown more clearly in Figures 4 and 7. Also in constructing the work or strip 29, it is the aim to provide the beveled or inclined edge 29a with a series of notches 287a and this can be accomplished through the medium of the type of machine shown in Figure 9, where the table 44 is removable, as hereinafter set forth.

In Figures 8'to 13 the frame 1 generally simulates the frame in the proceeding figures with the exception that it is entirely circular instead of segmental, yet the circular portions have the channel guides 32 for a carriage 32g. This carriage 32g comprises the supporting rods 4 for the motor bed 2h, which supports the motor, the motor shaft 2c carrying the cutter 3h, which operates on a plan 29, which is carried by a teinplet 28a, as in Figure 9.

In the construction in Figure 13 the templet guide has a link 42 connected to it, and said link 'is in turn pivotally connected to a bell crank 41,

whichv carries a roller 40. The bell crank 41 is pivoted at 43 to the table 30 and the roller 40 operates through a slot in a table 30.

Rollers 36b and 360 are provided in Figure 9 for guiding the templet 28a, the roller 360 being carried by' an extension of a rack 16a, and engaging a slot 16!: of the templet 28a. A weight 37a as in Figures 8 and 9 is provided for balancing the carriage and this weight is connected, as shown best inFigure 8, by the segments 32h. A stationary locating pin 39 engages into the templet 28a, the pin 39 also engaging in a slot 445 in the table 44 for guiding the table. 1

. In constructing the notches 287s in the beveled edge 29a of the strip or piece of work 29 the templet 28 as in Figure 14 is provided with a plurality of depressions 28m, which receive the locating pin 39 intermittently. In other words as the templet 28 moves, the locating pin 39 engages from one to the other of the depressions 28m, for the purpose of holding the work in position while edge notch 28k is cut. For example, referring more especially to Figure 9, the templet 28a is placed in position on the removable table 44, so that the rollers 36b and. 360 may engage therewith, the former with one edge of the templet 28a, the latter in a slot, while the pin 39 engages in the depressions 28m. The rollers 35b and 360 are provided merely for the'purpose of holding the teinplet in position, and so is the pin 39. The depressions are cylindrical, and after a notch 2870 is cut, the cutter 371 is moved away from the work, and then the templet is lifted on? the table 44 andplaced in position so that the pin 39 may engage another depression 28m, in which case the cutter 3h is moved back in position, and in this case the work or plank 29 is moved against the end of the cutter 3h thereby constructing another notch 28k.

However referring to Figure 4 the templet guide 16 engages in the groove 28g for guiding the templet and its work or plank 29 toward and from the cutting tool. The templet guide 16 with its upturned flange 30a is not the same as the pin 39. The pin 39 in Figure 9 engages depressions 28m, while the templet guide 16 in Figure 4 engages a guide groove 28g.

Springs 33 are mounted upon the rods 4 for tensioning the motor bed.

It is'obvious that the holding means for the work can be applied to the different constructions, in Figures 8 to 13 inclusive. It is also obvious that the automatic mechanism for justing the motor and its support, and for adjusting the teinplet guide, can also be applied to Figures 8 to 13 inclusive, hence it is believed that further illustration in -these directions is unnecessary. I 1 Theguide 36 is carried by the table 30 and insures the-prevention of the templet 28 moving too closeto the corner 3g of the cutter or'tool. As is obvious'from the showing in Figures 1 and 2 theedge or corner 3g of the cutter or tool at all times remains concentric with the center of the frame 1 of the machine, regardless of the position of the segment 4b carrying the motor. For example the segment 4b may travel on a substantial arc, the edge or corner 3g of the tool or "cutter at all times remaining concentric with the center-of the frame 1, enabling the plank or strip 29 to be given substantially anytype 0 pitch of bevel for the purpose intended.

The same theory and mode of operation is carried out in the modifications of the principles in Figure9', namely the cutter or tool3h operates concentric with 'the'frame 1, which is entirely circular, the tool or cutter never engaging 'or contacting with the templet, which is designated by the numeral 28a in Figure 9. The springs'38 act to hold the motor in a position with the cutter. or tool substantially up away from the work or plank or. strip being shaped.

In other words the springs 38 hold the motor in a position with the cutter up from the work, therefore when it is desired to cut the notches 28k the operator moves the motor down on the guides 4 in Figure 9, the cutter 3h then engages with the work or. strip 29, and thereby cuts a notch. .As soon as the notch 28k is cut, the pressure on the motor is relieved and then thesprings 38 will again move the motor upward and the cutter away from the work. As previously stated it is possible to move the motor down against the action of the springs 38 and set the motor in a position as may be desired, by tightening up on the screws 4w. These springs 38 are carried by the rods 4k, and operating against the collars 4m, in order to support the motor and its frame. However when it is desired to position the cutter or tool as may be necessary to performcertain work, the motor bed 2h carrying the motor may be movedagainstthe tension of the springs 38 'to the required position, after which the screws 4w may be set,=in order to hold the motor bed with its motorin the exact position necessary, to support the tool or cutteras might be desired to produce certain shapes to the plank or strip or the like. It is obvious that in Figures 9 and 13 the segment frame with the parallel supporting rods 4k canmove on a greater are than can be assumed by the segment-in Figure 1.

Referring to Figure 13 it is to be noted that the, springs'38 are eliminated and in this instance the carriage 32gwhich comprises the supporting rods similar to 470 are also carried by a segment adjustable in the frame, which may move on a much greater are than that in Figure 1. The rods-constituting the carriage 32g support the motor bed 32k and the motor 2112, and in this construction the motor shaft carries an entirely different form of tool or cutter 3w. This type of cutter or tool is especially adapted for channel ing or grooving outthe face of the plank or strip or the like, the channel or groove adapted to start at a very shallow depth at one end and adapted to increase to a greater depth at the other end. The depth of the groove at either end or any point between the ends depends entirely on the adjustment or position of the roller 40, which also depends entirely on the adjustment and position of the templet 28a inFigure 13.

In other" words when the templet 2811 in Figure 13 is operated through the medium of the quadrant and the electro-mechanical control as in Figure 1, the link 42 and the bell crank 41 adjusts the roller 40, therebygauging the depth of the cut to form the groove. In' order to groove or channel the face a plank or strip 46, the plank and templet are moved between the cutter or tool 3w and the upper face of the table 30, Figure 13, the shape of this groove longitudinally is shown in dotted lines in Figure 13 while its cross sectional area is shown in Figure 11.

Inj'Figure 1 there is one form of templet 28, which is so guided as to operate the work or plank 29 in various positions toward the cutter, while in Figure 9 another form of templet 28a is shown, whereas in Figure 13 still another form of templet is shown. r It is obvious that all the templets as herein disclosed'can be operated by any suitable mechanism co-operating with the rack 16 shown in Figure 1. However the quadrant and its associated parts is .one preferred form of mechanism for operating various templets, the gear 170 being in direct mesh with the rack 16 in Figure 1, the same engagement may be accomplished with the other racks shown in Figures 9 and 13.

While there appears to be three separate machines, such is not the case. The machines-shown in Figures 9 and 13 are merely modifications, and in disclosing these modifications other form of 'work to be accomplished has been disclosed. It is also obvious that the work performed by. the construction of machine in Figures 9 and '13 can be accomplished on the construction of machine shown in Figures 1, 2'and 4. Furthermore the mechanism disclosed in Figures 1 and 2 for operating the quadrant and for driving the motor'and the cutter can be applied to the modified form of machines in Figures 8, 9 and '13, such mechanism having been left off of the machines in Figures 9 and 13 for the purpose of simplifying. illustration. In accomplishing the work performed by. the construction in Figures 9 and 13, it is merely necessary to use different forms of templets and different form of templet guides, these form of templets and templet guides can be applied to the machine shown in Figures 1 and 2. r

In'Figure 1 the work 29 is moved across the face of the cutter 3, and by tilting the motor and its frame the angle of the cut on the edge of the work 29 can be varied. The fact is that the'work 29 ismoved by hand across the face of the cutter. It is obvious that by continuing the circular shape of the frame in Figure 1 to simulate that in Figures 9 'and 13, the motor 2 and the cutter 3 could be moved or adjusted to any position, such as shown in Figures 9 and 13.

In Figure 9 the plank or work 29 is supported upon the templet 28a and clamped on the templet 28a in any suitable manner (not shown), and in this case the templet is operated through the medium of the rack and an associated mechanism similar to that in Figure 1 so that the plank'or work can move toward the cutter.

In Figure 13 a different form of templet 28 is employed, and in this instance the templet with the work or plank 46 thereon is fed by hand through the machine, and in this instance the rack'associated with the bell crank 41 performs a function of retaining the roller 40 in engagement with the under face of the templet, so that the plank or work 46 can be formed with a groove, the depth of the groove in the plank 159 or work 46 being determined by the depth or groove in the underface of the templet.

Various types of cutters or tools-may be used and various templets, and furthermore theframe l in Figure 1 may be made completely circular thesaine as thosein Figures 9 and 13. I

Referring to Figures 12 and 13, in fact als to Figures 8 and 9, as well as Figures 10 and ll, the segments 4m inthese figures are a part of the weight 3 7a-and canbeinserte d in their guides by removal of certain parts of the guides.

The guide groove 30b in Figure 1 andthe guide groove 289 in Figures4 and are practically one andthe same. However the guide groove 30b in Figure 1 is in one type of templet while the guide groove 28g in Figures 4 and '7 is in another type of templet. The templet in Figure 1, it might be said, may be straight, and the groove 301) would extend longitudinally,therefore the work 29 in Figure l is laterally moved and a straight edge surface out by a tool 3, by reason of the fact that the work 29 would be moved past the tool by hand and under the roller 25, while the templet would carry the work in its passage past the tool. "The templet 28 as in 7 would hold the templet 28 against the guide 36.

It will be noted that the templet28' in Figure 7 is of a curved contour, therefore the groove 28g in Figures 4 and 7 would be of a curved contour conforming to the curvature of the templet 28, that is-in Figures 4 and 7.

Due to the frame of the machine having a guide concentric with the frame with means.op eratively adjustably supported in the guide (which is concentric with the frame) with driving means to carry the tool the cutting surface of the tool radiatesfrom the center of the frame, that is to say the cutting surface of the tool is next to the work. or plank,.the reby. insuring its being coincident with thecenter of the frame. The means carrying the cutting toolis always movable concentric with the frame, and due to this, and the fact that the cutting'surfaceof the tool im- 'mediately adjacent the plank or work isalways coincident with the center of the frame, the means Ii carrying the tool can automatically operate as in Figure l, or may be moved by hand as may be accomplished in Figures 9 and 13, and when moved automatically as in Figure 1, a beveled surface such as disclosedat 2911 may be imparted to the work or plank 29. In other words a bevel inclined in one direction at one end of the work 29, and inclined in the opposite direction at the other end of the work 29.
