bevel gear, 42 keyed to shaft 3S, is provided forl connection with gear 32 of turntable 21, in which case, gear 31 is disconnected.

On rails l2 and I3 of base l0 is a carriage 43 for a hollow slidable rpost 4,4Y which can be xed in position on the baseby means of engaging a bolt 45 depending from the post and through a slide plate 46 with'a nut 41. Post 44j is provided with Yatelescopic member 48 provided with a ball end 49 for supporting a socket 5|] of main arm or* compass beam 5|. Said telescopic member may be raised or'lowered in post 44 and retained in any xed Vposition by means of a set screw 52. VBeam 5| is movable on ball vend 49 in any,v direction and is joined therewith preferably at one end in order to permit `easy movement' during the reproducing operationsA I Adjacent hollow "slidable post 44vis another slidablehollow post 53V in'engagement with a carriage 54 and held in position against base l0 y by means of

55, 56 and 51. The interior of thepost iscorrugated for an equalizing rod 58 containing at onefend a. transverse openingf59 for opposed ballbearings 6|),v which are yadapted to form a frictional-engagement with corrugations 6|, Aby means of tensionedspring `62. VBy this arrangement,I therod remains in the position in which it is left in order to facilitate handling of compass' beam 5|.'k The upper end of rodi 58 Vhas a saddle 63 for a knuckle 64 The other end rof a socket 61 of a collar 68, thereby forming a universal joint.

Collar 68 has an interiorV circumferential groove for ball bearings. 69 for holding compass beam 5| in engagement. Said 1 beam is -also grooved in order to accommodate said ball bearingsV and can be easilyv rotated clockwise Vor ycounter-clockwise around the collar,`moved on ball end 49 as avpivot atan incline or decline or'at an angleV on its horizontal. It is to be noted that Vthe beam has adjustable counter weights 2l) at one end to facilitate handling of the same. Furthermorasaddle 63, knuckles 64 and 66, and socket 61, form a universal joint p thereby allowing for freedom of movement of on base |0, for setting apart at vany indicatedA position, brackets 1|V andl12 provided with, an index 13. The Lbracketsfhave a circular'groove r1.4 for ball bearings 15 to permit rotary'movement of a plate Vcasting 16 which has vav depend- `ing'member 11 for accommodating `adjustably mounted

tools

18 and 19. Ballbearings 15 are retained in position'between the

brackets

12, 13,

and plate casting 15, by means of screw bolt vand nut 08|. y

Brackets 1| are provided with tightening means 82 and a set screw 83 which fits Yin a groove 84 onthe beam- VSaid groove 84 acts as a guide for brackets 1| and 12 to maintain them on the same level. This arrangement eliminates all unnecessary level adjustments on the brackets.

The tail ends of plate castings 16 are provided with an opening for a bushing 85 to accommodate a set pin 86.

In order to move the

tools

18 and 19 on the vplate castings, a handle rod 81 is provided with a plurality of openings therein for pins 86. The rod is retained between the bushings 85 and the set pins 86 and is adapted to be rotated about theV center of the beam 5| as its axis. more,'tools 18 can be rotated about screw bolts 86 as their pivotal axes by pushing, raising or lowering the rod. Furthermore, said handle -rod` can be varranged Yon corresponding tail ends of the plate castings, as shown in Fig. 2,' whereby the `tools will move invunison and parallel to each other during a reproducing or cutting operation. If the rod is connected to the diagonally opposite tail ends of the plate castings, as shown schematically in Fig. 6, thetools move so that a line extended fromvthem would intersectv each other. Furthermore, the diagonally oppositeV connection ofthe rod with the'plate' vcastings permits enlarging or reduction of the side of the object directly opposed to the model, when the turntables arefrotated relative counter-clockwise directions'. In other Words, by this arrangement, mirror images off the form are obtained in one operation.

FromY the foregoing description taken in connection with the accompanying drawings, it is to be noted that an even and uniform motion is `impartedto the turntables which are arranged in a common level or plane. Furthermore, the turntables may be moved along said plane or level at any desired interval without requiring any tedious adjustments, and rotated in unison or counter 'tov each other. Also, the cutting or working tools are adjustable to any angle for working in two dimensions thereby permitting Yeasy enlarging, reducing or reproduction of forms. The tools are mounted on an easily balanced beam which'moves about a pivot and which can be easily counterbalanced or moved about in a gyrating or swinging manner.

The essential features of the invention include a level base, a plurality of adjustably slidable and rotatable turntables and an easily operable pantograph device which is rotatable on its Vhorizontal axis and can be raised, lowered or swung about a pivot. Furthermore, said pantograph device is counter balanced and permits working invention.
