I 1" 7 Upon the table 5 is mounted a cross slide 1 guided; by. trackst' and movable in a plane at right angles to the 'axis of the spindle I.

The upper sides of the members I I are provided with curved surfaces Hz: which are engaged by spring actuated plungers I3, which plungers are mounted on the arm 2 which carries the spindle I and are yieldably thrustdownward by springs l4.

A short shaft I5 is rotatably mounted in the slide near the rear end at one end thereof and is provided with a downwardly extending arm I6,

Which is connected by a link I! with a corresponding downwardly extending arm I8 attached to the the slide above the shaft I5, overhangs the upperedge of-the rack 2i and holds it into engagement with the gear is. For reasons hereafter described the gear 26] is interchangeable with other gears of other diameters and for that purpose the guide block 23 may be replaced with similar blocks of diiierent dimensions to properly hold the chosen gear in mesh with the rack and the end of the rack attached to the bracket 22 is vertically adjustable so that it may be properly alined with the gear in use.

Stop screws 24 are mounted on some part of the structure which does not slide horizontally such as the table 5 orpne of the tracks 8 in a position to be engaged by the slide 2 to limit its sliding movement in either direction and these screws may be adjusted so that the extent of the sliding movement may be varied or if desired for certain operations hereafter described both screws may be adjusted to' simultaneously engage opposite edges of the slide so that it will be held immovable. Stop screws Hm are also provided on a fixed portion of the slide 'I' and located to engage opposite sides of the lever I9 to limit its oscillating movement in each direction.

Operation It will be seen that the mechanism described provides a machine in which thereis a spindle rotatable upon a vertical axis and having a cutter of the rosette cutter type and below which there is a table movable toward and away from the cutter in a direction parallel with its axis. Upon the table the work holding clamp provides means for-holding a strip of molding which preferably has previously been provided with an upper curved surface and this'molding is held in position to be engaged by the cutter when the table is moved upwardly. V

Assuming that the work hereafter termed molding and generally designated as 25 is in place in the lowerclamp member 9 between the. guides 9a and that the table 5 is in lowered position, then in this lowered position the upper clamping members rest lightly upon the upper surface of the molding and the molding maybe moved longitudinally in the clamp. In this lowered position it is to be understood that. the plungers I3 do not engage the upper surface Ila of the clamp members II.

The table may then be elevated by suitable meansprovided for that purpose and during the first part of such elevation the plungers I3 engage the clamp members I I. and press them firmly against the molding so that it is held tightly cutter 4. While the parts are held in this elevated position with the cutter operating its full desired depth in the molding and with the parts arranged as shown in Fig. 2 the lever I9 is man ually oscillated which rocks the work clamp and molding therein on the trunnions it by virtue of the arms I6 and I8 connected by the links I! and at the same time movesthe slide l on the tracks 8, this sliding movement being caused by action ofthe gear 20 travelling onthe rack 2!. These movements produce what may be termed a rolling movement of the molding relative to the cutter 4.

A rocking movement of the molding relative to the cutter may be accomplished by removing either or both the rack 2i and the gear 28 and by adjusting the stop screws 2% so that they will both engage opposite sides of the slides l to holdthe slide immovable in which case oscillation of the lever !9 will merely cause rocking of the clamp and work on the .trunnions ID trate the operation accomplished by the rocking movement and the work accomplished there by, Fig. 4 shows: the molding 25 in a position where the cutter 4 is operating to cut a design with the molding turned toits extreme position in one direction. The center point If! indicates the axis of rocking which is co-incident with the axes of the trunnions wand by moveinent of the lever ii) the molding is caused to rock while the cutter icontinues to operate upon it causing the cutter to follow the arc-shaped surface of the molding which are is concentric with the axis Iii.

The rocking movement of the molding may be continued'throughout its entire curved surface or maybe stopped wherever desired producing a design elongated crosswise of the molding, said design having curved ends and elongated intermediary portions. The extent of movement of the work is limited by engagement of the lever I9 with the stop screwslfia which may be adjusted as desired. In the design shown a slight overlapping of the figures occurs, that is, the cutter in producing one design overlaps longitudinally of the molding the next design which produces the effect shown. Greater or less spacing of the designs longitudinally of the molding would produce different effects performed by the same cutter. l g

Operation of the device to out a design by the so-calledrolling process and designs, so out are illustrated in Figs. 9, 10, 11, 12 and 13. To produce this operation and result the machine is arranged as shown inFig. 2 with the gear 29 and rack 2I in place and the stop screws 2 5 ad justed, to permit movement of the slide l. With the parts so arranged and assuming that the work is in engagement withthe cutter and the lever I3 moved to one extreme position the molding will assume the position shown in Fig. 9 and as the lever I9 is moved to its opposite position the moldingwill be caused to rotate about the axis I6 caused by movement of the arms i6 and i8 and the link I! and at the same time the axis i S will be moved transversely of the molding causing the arc surface of the molding to assume a rolling motion relative to the cutter.

If it is desired by this rolling operation to'cut a circular design, orin other words, a design which would, if developed on a plain surface be circular, the cutter designated at to. in Figs. 9 and 10 should be of sufficient diameter so that its cut- 'ti-n'g edge will be of-a length equal to the length oiithe arc of the design. With a gear of proper diameter to advance the axis t at'the same speed as rocking *o'f the periphery of the molding, or in other words gear having a pitch diameter equal to the radius of the-curved surface of the molding,

. a truly circular design cut intothe curved surface may be produced as' shown in Fig. ll. However, by varying the diameters of :gear as relative merits: both directions.

"tothe radius offthe'moi ing so that the axis it will beadvanced eith r slower or faster than the rocking or the 'peripheryof the molding, ellipses having their greatest diameters extending. either transversely or -longitudina lly or" the molding .rnay be cut as illustrated in "Figs. 12 and 13'. In performing the'rolling-operation either the stop operation may be beguninithe middle of the design and completed'by moving the work both ways respectively therefrom as well as in any other way.

It 'will also be u'nderstood that after completion of cutting a single :design the table 5 is lowered which automatically releases the up er clamp members Ma from the plungers' i i and'permits the molding to be moved lengthwise to a proper position where repeated elevationoi the table will out another design and this operation repeated throughout the entire length of the molding.

Themachine has been shown and described as withtl'ie spindle i mounted in the first arm 2 and the table 5 movable toward or away from the spindle and cutter 4. An identical result may be obtain'ed'in reversing the movable parts wherein the table 5 with'the af'oredescribed' parts mount ed thereon is fixed and the rotating spindle! and knife 4 mounted to move toward or away from the work.

In the claims the termrosette cutter is to be defined as meaning that type of cutter having its cutting edge extending substantially.transversely of the axis of rotation of the cutter.

The invention has been herein shown and described in its preferred form in which the work is rocked or rocked and moved laterally on an axis extending substantially at right angles to the axis of a rosette cutter but the invention is conceived in various modifications in which other types of cutters may be used and wherein Various results are obtained by rocking the work on axes located differently than perpendicularly to the axis of the cutter and more particularly where the rocking movement of the work is accompanied by a lateral movement of the axis. The various modifications are not specifically shown nor described but the invention as defined in the appended claims is to be considered compre-. hensive of all forms of structure coming within their scope.
