The lower end ot the shalt 15 is thread-- ed and provided with a suitable washer 13 and nut 19 which maintain the shaft in the standard.v 2O designates a ifricticn block and 21 a set screw which is threaded into the standard and bears against the ilfriction block, whereby the table may be secured against rotation on the standard, it desired, 'lfhe 'table may be provided with any suitable work-holding or retaining means, slots 22 being shown in the embodiment illustrated for the purpose oli receiving the usual workholding dogs or chucks (not illustrated). 23 designates a handle iii-red to the table whereby the table may be manually turned,

The standard 11 supports the rotatable and gyratory members and cutting tools or scribers oit' the appara-tus and is provided with means for holding the major axial shaft of the cutter regulating and adjusting system. ln the preferred 'form illustrated, the standard 11 terminates in a yoke or neck Q/l which is provided with a pair c'l substantially vertical if-shaped slots or key ways 25. 26 designates a movable spindle head which is preferably provided with projecting, vertical tins or guides which are adapted to enter the slots or key-ways zo in the yoke to maintain the spindle head in position while permitting vertical movement of the spindle head withinV the yoke. As best illustrated in Figs. l and i. ol? the drawings, it is considered preferable to construct this spindle head in two duplicate parts, each part bearing one of the :li-ns or guides referred to above. T bese parts also bear lugsl or ears 27 which are threaded to receive a screw 23 for securing the parts together. The screw 28 may be provided with 30 designates a sleeve which is keyed as at 32 to the interior ot the spindle head Q6, and, as illustrated. this sleeve is bored to receive the major spindle 31. By reason of the key and key-way counection between the sleeve and spindle head, the sleeve free to move vertically in the head but is held from turning therein. T he sleeve 30 preferably projects above and below the spindle head and is externally threaded atV its upper end at 34 to receive the regulating nut or wheel 35 by means o'l which the spindle head and the rotary and gyratory tool supports may be raised or lowered, and the upper end ot the bore oit the sleeve lis preferably enlarged as at 36 to provide a seat for the collar or enlarged portion 37 of the spindle. The upper end ot the spindle extends through a bearing or boss 33 and carries a pinion 39 in mesh with a pinion e() which drives a shaft 41. rlie pinion 39 is slidably mounted on the upper end ol' spindle 3l with a slot and key connection as indicated at K so that the pinion will turn with the spindle but the spindle may be moved lengthwise through the pinion. The bearingboss 3S Afor tie spindle and the bosses for shaft l1 may be supported in any suitable manner. ln the embodiment illustrated, the bearing 33 is lormed on a bracket mounted on the standard 1l and this bracket also supports bosses 413 and tlin which sha-it` 41 is journalled. 45 desigi'iates a gear which is keyed to the shaft (lil. designates a shaft carrying 'a (lrivingpinion l? and preferably journalled in a boss 48 formed in a portion ot the bracket 42 and aA the gear ratio at this point, the pinion 59 may be replaced by a4 pinion or gear ol dil?- lierent diameter, proper adjustment being made ot the slotted arm 51 through means ot the set-screw 53 to compensate t'or the difference in gear diameter. By these means, suitable change may be made in the rela-tive rate of speed at which the. pinion L7 is driven. ln the embodiment illustrated, the shaft 46 is provided with a pinion 5-1- which is in mesh with pinion 55 secured to the shaft 56. whereby rotation of the spindle 3l is transmitted to the shaft 56. he shariP t is rjournalled at one end in a part of Athe bracket 50. the other end ot the shaft being journalled ina bracket 5? adjacent the table. A pinion 58 is secured to the lower end oit shaft 56, which pinion meshes with a pinion 59 rotatably mounted on a. swinging plate 60. The plate 60 is preferably mounted to swing about the lower end of the shaft 56 as an axis and carries a second pinion or gear 61 which is in mesh with pinion 59 but is not in direct engagement with the pinion 58. 62 designates a gear mounted on the bracket 5T, this gear 62 being in mesh with a driving gear or wheel 63 rigidly secured to or mounted on the rotatable work-supporting table. The swinging plate 60 acts, when swung in one direction, to position the gear 59 as a driving connectionbetween pinion 58 and gear 62, and when swung in the other direction operates to engage pinion 61 with gear 62, whereby ies the drive will be from pinion 58 to pinion 59, thence through pinionr 61 to gear 6'2, the result .being a reversal of the drive relatively to the driving` connection effected by swinging movement in the lirst named direction. The swinging` plate is provided Vwith a handle 64; and is also provided with means tor releasably holding said plate with its gearing in the desired driving position. ln the form illustrated, these means comprise a pin or lug 65 mounted on the swinging arm, and a plurality ot recesses 66 in the bracket 5?, into anyone of which recesses the pin or lug is adapted to engage. suitable selection and change ot the pinions which take the drive from shaft lll, any de sired relative speeds or rate of rotation oit the shaft 56 may be obtainedwhen the spindle is turned, and by suitable `adjustment of the" swinging pinion-supporting plate at the lower end ot shaft 56, an adjustment may be secured whereby the tablevremains stationary or is rotated clockwise or counterclockwise at the option of the operator.v

The invention' also includes means which are readily accessible to the operator for raisingY and lowering the spindle head,V spindle and associated parts. InV the apparatus illustrated, these means comprise a rack bar 67 which isy secured vto the spindle head 26.'

,Cooperating with this .rack 'bar is a bell crank lever 68.pi voted on a suitable'pin 69 and' operated through means of ay chain 70 which is connected at one end tothe bell crank lever and extends overguide pulleys 71 liournalled in the hollow standard' o'l' the machine. The bellr crank lever 68 has suit able teeth engaging the teeth ot' rack bar 67.

rllhe chain TO is connected at its otherend, to a suitable counterwe'ight 'T2 and 1s actuated machine. p counterweig'lit'm b v means of .a link 75, whereby when the treadlejor -pedal is depressed, the bell crank leverraises the rack bar and spindle head. Thespindle head and supporting members and the like are o tsutlirient weight to overcome the counterweight to move to and remain in work-engaging position, Thus, Awhen the tool has been set to work toa desired depth, by adjustment of wheel it mayv be permitted to be engaged with and disengaged troni the work by manipulation ot treadle 78. 'Vhilethe spindie-head raisin;Y and lowering mechanism illustrated is preferred at this time, it is'obvious that other mechanism may be utilized.`

for the same pijirpose andthe invention is in ticular form shown.

The mechanism for automatically regulatine` the movements of the cutters or tools consists ot a plurality of supporting mem i bers or wheels arranged to revolve about the y no wise to be considered restricted to the'par- Y end of thesleeveO.

The opera-'tion of the machine vis as follows: Y

The Work or material to be routed or engraved is held on the rotatable table by means of Suitable chucks or dogs engaging the slots QQ-of the table. By actuation of the

handles

83, 119 or 129, the tool 1114 may be Vmoved towards or from the axis of the machine. The pinion 108 or the pinion 109 may be set to engage the pinion 103 which rotates the first planetary member. lf With ,these gears set in the manner indicated, the major wheel or supporting member ,77 is turned by hand, the result will be that the cutting tool is revolved about the axis of the spindle 31 and at the same time is rotated either clockwise or counterclo'ckwise, depending upon which of the pinions 108 and 109 is in mesh With the gear 103. This action may be modified, if desired, by en- .gaging the pinion 97 with the gear 98, in which case in addition to the major revolution and the clockwise or countercloclrwise rotation, the sliding block 79v will, as the revolution progresses, be moved toward the axis of revolution, resultingin a modification of the design. One of the movable pinions on the shaft 115 of the first planetary member may be engaged with the axial pinion of thesecond planetary member so .as to result in rotation of the second pla-netary member about the axis of the sliding block 117; likewiserthe sliding pinion on the end of the shaft 115 may be engaged With the worm rod driving pinion of the first planetary member resultino' in a shifting of the aXis of rotation of the second planetary member in the manner described above. 1n addition to these movements of the cutting tool or scriber, which may be regulated and adjusted to result in the production of an infinite number of designs, yin straight lines, in angles, squares, polygons, tangents, circles and Atheir many distortions ,or parts such as chords, arcs, involu-tes, spirals and ellipses; by suitable combinations Y,of revolution and rotation, modified in some instances during the revolutions by actuation of the worm rods, tangential arcs, abscissas, para-bolas, hyperbolas, ovals, cycloids, epicycloids, hypercycloids, interior epicycloids, scrolls, helica'ls,'ionic if'olutes, In addition to the the designs or figures may be modified by suitable movement of the 4work-supporting table which may be rotated when the supporting wheels .are revolved Aand the spindle 31 is turned. This turning movement of ythe spindlel is transmitted to the shaft '56, from Which shaft it is transmitted to rotate, either in a clockwise or counterc'loc'kwise direction, the table 12, through the medium of pinions and gears 59, 60, 61 and 62. It is thus possible to set the par-ts of the machine for a desired revolution and coor counter-rotation of the cutting tools or scribers, to modify these movements by manual operation of the several worm rods in the supporting members, to shift the axes of the supporting members or of the tools, and in addition thereto, to rotate the Worksupporting table either clockwise or counter'- cloclrivise or to advance the supporting table with an intermittent rotary movement or to set up any modi-fied movement of the table desired. The result may be, desired, a cutting or engraving of the highly confused and intricate figures and lines used on bank` notes or safety paper.
