The frame of the machine comprises a hollow column l, having a base 2, and a top 3. The column 1 is provided at its front with vertical guideways 4lon which slides the apron 5, said apron having corresponding guideways 6 and balls 7 being interposed between the said guideways, as best shown in Fig. 9. The vertically sliding apron 5 is provided with a counterbalancing weight 8 connected thereto by a differential gearing comprising the shaft 9 provided with a small wheel 10 and a large wheel l1 from the former of which extends a chain or belt 12 passing over an idler 13 to the apron 5, while a similar chain or belt lllpasses around the larger wheel 11 down to the weight 8. The

feed of the apron 5 is downward and is effected by a vertical screw 15; swiveled at its lower end in a bearing 16 secured to base 2 and there provided with a worm wheel 17 actuated by a worm 18 on a horizontal shaft 19 provided with a drive pulley 20 connected by a belt 21 with a drive pulley 22 on a shaft 23 at the rear of the column 1. This shaft 23 has a drive pulley 24 driven from a source of ower not shown through-a belt 25.

he ffeed'screw 15 extends through a split nut 26 mounted in a casing 27 secured to the front of the apron 5, see Figs. 1v andv 4.

V This is av well known quick release mechaiism and compri-'ses in'detail the nut 26 in twohalveshaving cam grooves in their upper faces engaged by pins 28 depending from a plate carriedA byl the rotating hub of l a release lever 29 mounted to turn freely on 20V the upper non-threadedendoffeed screw 15. This releasing lever is provided with a torsion spring '30 which throws it to the rightto separate the sections, of nut 26 by the pins 28 when itl is released from its retracted position by the latch 31. Latch 31 is form'edof a counterweigh-ted bar pivoted between its ends, as at 32, to a lug 33 projecting up from casing 27. The longer heavier end of latch 31 extendsacross a rod' 34 i'iXedly secured to an arrn'in which the upper plain end .cf the shaft 15 turns; the lowerV end of the rod 34 beingsecured in

bearings

35, 36 on bearing 16. A stop37 is adjustably secured on rod 34 in the downward path of the weighted'end of latch 31' so that when said weighted end reaches the stop 37 the latch will be rocked and itsy opposite end depressed out of contact with the lug 38 on the lever 29, whereupon vthe Ator- -sion spring will throwY thelever and cause screw 15 will feed the apron 5 down the dis- `tance for which the feed is set, at which point the splitnut 26 will be automatically f` released 'from Vthe screw, whereupon the operator by pressing on the foot lever 42 may quickly raise the apron to the starting point, where the nut will be again thrown into engagement with the Screw. `On the upper side ofthe apron 5 is mounted a horizontally sliding saddle 50 which carries the pattern holder and the blank holderstobe presently described. The ends of the saddle 50 overhang the ends of the apron 5, as

shown in Fig. 2, and 'ballfbearingsfl are interposed between the guideways 52 interposedbetween said overhanging or overlapping ends. Intermediate of these guideways are tracks53 upon which travel rollers 54 mounted on the lower side of the saddle 50. Thesaddle is drawn inwardly or rearwardly by a weight 90 suspended from a chain 91 passed over a segment 92 mounted on a bracket 93 secured to the rear side of the apron 5 so that the saddle 50 is moved vertically by the apron and its feed screw 15 and inwardly by the weight 90.

To the upper side of the saddle lis secured a series of casings 56, each provided on its upper side with an upwardly and inwardly curvedl hollow standard 62, seven being shown. The middle standard 57 is p'ro'- vided at its upper end with a vertically adjustable screw 58, carrying a sleeve 59 `to the lower end of which the clamping and centering pin 60 of the model 61 is secured, as shown in Fig. 4, by turning the screw 58 the pin 60 is raised and lowered.V

The six standards 62 are allprovided with clamping devices for the tops of the blanks 63. This clamp device comprises a vertically sliding sleeve 64 mounted in a tubular bearing head 65 on the end of `standard 62. The sleeve 64 has its bore reduced at the lower end to receive the stem 65 of a centering or clamping pin 66, whichY is loosely mounted therein. The stein 65 vhas van annular collar 67 engaged by a threaded 'nipple 68 Vscrewed into the lower end of sleeve 64, so'that'the clamping pin will be free to turn and at the same time will be raised and lowered with sleeve 64. In the upper end ofthe sleeve 64 is a headed screw 68 under the` head 69 of which is a spring 70 which liftsthe sleeve 64 and clamping pin 66 away from the blank 63. In a fork "71 lat the upper end of arm 62 is pivoted the clamp actuating lever 72, the cam head of which has two Vcam surfaces 73, 74, as shown in Figs. 5 and`10,`to engage the head of screw 68'. Vhen the lever 72 is swung down the cam surface 73 engages the head of screw 68 and forces the said screw, the sleeve 64 and the clamping pin 66 down upon thetop vofthe blank. When the lever is 'swung up to theposition shown in Fig. 10 the spring 70 lifts'the screw and attached parts and lforces the head of thescrew against the cam surface 74 which holds the lever 72 inv its raised position. In vertical alinement with the'pattern clamping screw 58 is a shaft 76 mounted in bearings 77 in casing '56 and provided at its upper .end with a headv`7 8, having pins 79, to enter recesses in the lower cnd or base of the pattern 61. This shaft 76 is rotated by meansof a worm wheel 80l 'i engaged by one of a series ofworms 8,1' on worm shaft 82. This worm shaft 82 is a line shaft extending throughall of the 'casings 56, and engaging the siX worm wheels 60 on the. six blank-rotating shafts 83 so that all seven shafts are rotated in unison.

Ei'ery blank-rotating` shaft 83 has its upper end roughened, as at 84.4, to afford a firm `grip on the base of the blank 63, see Fig. 9. Upon the upper sides of the casings 56 are formed integral bearings 35 and provided with bushings S6 for the shafts Mounted on the upper. ends of these bearings are secured dust collars S7 to rotate with the shafts. U pon the shouldered exteriors of the dust collars 37 are splined at 88 loose vertically movable positioning Vilates 89 carrying the centering` or positioning studs 100 against which the lower edge of the base of the heel blanks 63 is placed to properly position them. These studs 100 have their stems mounted in apertures in the plate 89 and above the plate are formed with overhanging eccentric heads 101 so that by turning the studs to bring` the heads into the desired positions different sizes of heel blanks may be positioned on the upper ends of the shafts S3. The studs 100 are held in their adjusted positions by means of the setscrews 102, as shown in Figs. 11 and 12.

To lower the plate 89, and bring the heads 101 of the studs below the plane of the upper ends Set of the blank-rotating shafts 33, l provide the lever 105' pivoted at its outer endto the bearing- 106 in the casing- 56 and at its opposite end provided with a yoke 106 bearing against the under side of the said plate 89, and to this lever 105 is pivoted the lower end of a link 107 extending up through standard 62 and slotted. at its upper end to receive the clamping lever, as shown at 108. It will be seen, therefore, that when the lever 7 2 is swung' up to raise the clamp 66 it will at the same time raise the lever 105 and lift the plate 89 and its

studs

100, 101 into the position shown in Fig. 10 so that a blank may be properly positioned. A downward f movement of lever 72 will depress the clampin;I pin 66 into engagement with the blank and hold it down on the head S4 of

blankrotating shaft

8,3 and at the same time will depress lever 105 to lower the plate 89 and studs 100, as before described. A set-screw 109 projects through the upper end of lever 107 to nicely adjust the lifting action of lever 72 upon the link 107. y

At the lower rear right hand corner of the column 1 is a bearing 115 in which isl mounted a driven shaft 116 provided at its inner end with a loose pulley 117 connected by a belt 118 with a smaller pulley 125 on the shaft 23 before referred t6. The pulley 117 is engaged with the shaft 116 (Fig. 9) by means of a clutch section 119 pressed toward the pulley by a spring 120 to bring the clutch tooth 121 into a recess 122 .in the pulley hub. rPhe sliding; clutch member 119v is pressed away from the pulley 117 by means of an arm projeatingl rearwardly from the lower end of a vertical rock shaft 121. rlhe rock shaft 121 is mounted at its lower end in a step bearing` 127 and at its upper end passes tl'irough a beaming sleeve 128 at the rear end of the oracket carried by the apron The sleeve 128 slides freely on the upper end of the rock shaft 124. Mounted to turn with and slide on the upper end of rock shaft is its actuating arm 126 operated from a cam 130 on the clutch-actuating latch bar 131 sliding` at its rear end in a guide projecting from the sleeve bearing 126, see 9. rlhis arm 126 is moved up and down .en shaft 124C by sleeve 128 which is transversely slotted to receive the inner end of said arm.v

This clutch-actuating latch bar 131 extends to the front of the machine between the saddle 50 and upper face of apron 5, as shown in Figs. and 10, and is actuated by the horizontal movement of the saddle in both directions, as will now be described. The front end of the latch bar 131 extends through a slotted plate 132 depending from the front wall of the saddle 50 and on its outer side has an elongated strap 133, to which is pivoted a latch 134i-, the nose 135 of which projectsthrough an aperture 136 in the strap so as to lie in the path of the.' plate 132 when the saddle 50 moves inwardly. 1t follows, therefore, that the saddle 50 will.. through plate 132 and latch nose 135, move the latch bar 131 rearwardly and so move the cam 130 out of engagement with'the Clutchactuatingarm 126, which will 'permit spring 120 to throw clutch 119 into engagementk with pulley 117 that drives the shaft 116, which in turn drives'the worin shaft 82 and, through it, the blank rotating shafts 83 and the pattern or model shaft 76. y

The. shaft 116 has a bevel gear 140 which Vmeshes with a gear 141 on the section 112 of a. telescopicv shaft.v the other section 1%3 of which has a bevel gear 114 meshing' with a bevel gear on the worm shaft 82.

The two sections of the telescopic shaft slide in a splined connecting' sleeve 116.y sce Figs. 1 and 2.

The opposite gear-carrying` ends of the two shaft sections 142,` 143 are mounted in

angle boxes

117, 148, the

horizontal sleeves

119 and 150 of which are lmnp; loosely on the shafts 116 and 82, respectively. This connecting' drive gearing for the shafts 116,

32 vprovides for the free horizontal and vertical movement of the saddle 50 and renders the employment of universal oints unnecessary.

By pressing on latch 134 to throw its nose 135 out of the path of the plate 132 the saddle 50 and parts carried thereby may be moved inwardly without moving the latch bar 131 and so the clutch 119 will be held away from pulley 117 so as to prevent rotation, whenever desired, of the blank-rotating shafts 83 and pattern-rotating shaft 76. The latch bar 131 may afterward be thrown rearwardly by hand to allow the spring 120 to throw the clutch into action and start shafts 837 76 to rotating.

The lower edge of the latch bar 131 is provided at its outer end with an outer recess 150 which engages the lower wall of the slotted plate 132 so that when the saddle 50 is moved outwardly the latch bar 131 will,

be moved outwardly and so move the cam 130 into engagement with arm 126 of rock shaft 124- and so swing arm 123 to the left and release clutch 119 from pulley 117 and thereby stop rotation offshafts 83 and 76. The lower edge of latchbar 131 is further provided at its outer end with an inner recess 151 which, when the saddle 50 is moved to its outermost position, will'engage a stop lug 152 on top of apron 5, and so hold the saddle 50 against inward movement; the latch bar recess 151 at this time being in engagement with forward recess 150. This construction provides for the automatic starting of the pattern and blank-rotating mechanism as well as for their being started' by hand when moved up to the pattern controlled rotary cutters 200 to be presently described.'

On the forward side of top 3 of column 1 is provided a series of transverse guideways 180, in which is mounted a series of brackets 181 provided at their rear ends with swiveled adjusting screws 182, a'nd along their lower sides with guides 183, litting accurately in the guideways 180 and held rigidly in their adjusted positions by the overlying clamping plates 184 provided with securing screws 185. The swiveled adjusting screws 182 pass throughthreaded apertures in the lugs 186 projecting up from the table top 3. There are six of these cutter brackets, three ateach side of the middle of the top, one opposite every blank holder. On the front vertical face of every bracket 181 are provided upper and lower bearings 187 in which are clamped the vertical sleeves 188 having ball races 189 carrying ballbearings 190 in which are mounted the six rotary shafts 201 carrying at their lower ends the cutter heads 200 and at their upper ends provided with high speed pulleys 202. By adjusting the brackets 181 and the sleeves 188 the cutters may be exactly adjusted with respect to each other and to the blank holders. The circular cutters 204 are cup-shaped and are pivoted at their centers in radial recesses 205 in the cutter heads 200 and are not pattern-shaped as in prior heel cutting machines. Superposed on the cutter heads200 are circular roughing out lsaws 206. VvThese cutter heads. and their' cupshaped cutters and roughing out saws are not of my invention.

The pulleys 202 are constantlyl rotated by belts 207 from. larger pulleys 208 on a line shaft 209, which in turn is connected by a belt 210 to the same shaft, not shown, to which belt 25 is belted.

The working edges of all of the cutters are adjusted to the same horizontal line and all ofthe cutters must lie in the same horizontal plane so that when set for operation they will be presented to the blanks, as shown in Figs. 1 and 5. Furthermore, the

Vcutters lie in the same horizontal plane with the pattern-controlled wheel 300, see Fig. 2, the relation of which to the pattern 61 is clearly shown in Figs. 4 and 8. This pattern controlled wheel 300 is on the lower end of a vertical shaft 301 mounted in a ball bearing sleeve 302 ycarried in bearings 303 on the front face of a horizontally sliding carriage 304 provided at its lower edges with ways 305 engaging guides 306 on top of table 3 and provided with a retracting spring 306 tending to constantly withdraw the carriage and pattern-controlled wheel 300 away from the pattern. On the rear side of the carriage 304 is a vertically adjustable block 307 carrying a rearwardly projecting tongue 308; the block being adjusted up and down by means of a manually operated shaft 309 having a bevel gear 310 at its rear end meshingwith a bevel gear 311 on the upper end of an adjusting screw 312 engaging a threaded aperture in block 307. By rotating shaft 309 by means of its hand wheel or crank 309', tongue 308 may be adjusted from a central position onthe fan board 315 to any desired position above or below its center or horizontal pivotline.

This fan board 315 is provided with trunnions at its opposite sides journaled in bea-rings 316 on a bracket 317 fixed to theftop 3. To the right hand' trunnion, Fig. 3, is fixed a disk 318, to which is adjustably secured yby bolts 319 a second disk 320 at the inner end of a short rock shaft 321 mounted in a bearing 322 on top 3. To the outer end of rock shaft 321 is fixed a rearwardly extend- AingV actuating arm 323 provided with a curved slot 324 in which is adjustably mounted a pivot bolt 325 on which pivots the upper end ofV a link 326. By means of the bolts 319 and the slots 327 through which they pass, the desired permanent angle of the fan board 315 may be adjusted. The lower end of the link 326 is pivoted by bolt 328 to the forwardly extending arm of a bell crank lever 329 pivoted at its angle by a pivot bolt 330 tothe side of column 1'. TheY 1 izo nected by a shortinclined slot 336. When the squared portion of the actuating stud 331 lies within either

portion

334 or 335 of the slot no movement will be imparted to the bell crank lever 329 and so none will be transmitted through link 326 and arm 323 to the fan board 315, but when the sliding link 333 is moved to bring the inclined slot 336 into operation its walls will engage stud 331 and rock the bell crank lever 329 and the fan board 315, Motion is imparted to the slide by means of a horizontal lever 334 pivoted between its ends, as at 335 to column 1 and having a forked rear end 336 engaging a pivot stuc on the lower end of said slide 333. The longer outer end of the lever 334 is provided with a longitudinal slot 338 in which works a stud bolt 339 adjustably secured at its inner end in the slot 340 of a bracket 341 projecting outwardly from the vertically movable apron 5. lt follows, therefore, that the throw of lever 334 may be regulated by adjusting the stud 339 in or out along slot 340 in bracket 341, see Figs. 1 and 8. By this fan

board mecha nism

308, 315 and the links and levers connecting Jthe fan board 315 with the vertically movable apron I am enabled to produce graded sizes of heels, as shown in Figs. 6 and 7. The tongue 308 is shown, see Fig. 8, engaging the center of the fan board 315 so that, no matter how the fan board may be rocked, no change in the position of the pattern wheel 300 with respect to the pattern 61 willtake place and no change of the wheel 300 with respect to the working line of the several rotary cutters 200 will take place, but the pattern 61 will move downwardly across the wheel 300 and the blanks will likewise move downwardly across the fixed horizontal plane of rotation of the cutters 200 and so duplicate the pattern. In order to give the desired grade for different sizes of heels, the tongue 308 will be adj usted above or below the horizontal axis 321 of the fan board 315, and then when the fan board is rocked from a vertical to an inclined plane, as shown in Fig. 8, the carriage 304 will be given a forward or lrearward movement, according to whether the tongue 308 is above or below the fan boardaxis, and so the carriage 304 will carrythe model wheel oi'itwardly or inwardly toward the pattern 61 and so move the rotating blanks farther away from the rotating cutters 200 or permit them to move closer tothe cutters and so produce larger or smaller sizes of heels. Obviously, therefore, the grade given by the cutters may be made to fade away or vanish at any desired point, according to the amountv of inclination given the fan board and the length of time such inclination of the fan board is allowed to continue. This will depend upon the adjustment of the stud 339 which regulates the throw of lever 334.-

rml 5...),

When the stud 325 is in the position shown in Fig. 8, the fan board 315 will always be moved back to a vertical position, regardless of the position of stud 339 in the slot 338 of lever 334.

To hold the fan board 315 at any desired angle while its actuating slide 333 travels in a straight line between the permanent angle given by adjusting screw 319 and the normal vertical position for `the purpose of giving the grade to the heel from the end of the vanishing point 400, see Fig. 6, to the tread, the actuating stud is moved outwardly in slot 324 from the position shown in Fig. 8. Thus the fan board will always set at an incline and so operate the tongue 308, which will have been properly adjusted above or below the fan board axis, according to whether the grade is to be added or taken away above the vanishing point 400, Fig. 6. The outside broken line above point 400 shows the extreme outer grade, but it will be understood that the space between the dot-ted and full lines is to be proportionately divided and continued from the corresponding dotted lines below point 400.

By my improved construction heels may be formed at one operation and these heels may be made exact reproductions of the model and of any desired size. Furthermore, by means of the fan `board mechanism, above described, the grade above the vanishing point 400 of the heel can be made in any proportional part of the grade at the base of the heel. A brief description of the operation of the machine is as follows, the parts being in the position shown in Fig. 10, where the apron 5 is in its uppermost position and the saddle 50 in its outermost position: A blank 63 is in position within the studs of the positioning pla-te 89 ready to be clamped. The lever 72 will now be depressed and the blank clamped in place on the rotary shaft; the positioning plate 89 being depressed at 'the same time below the level of the upper endv of shaft 83. rThe saddle 50Tand the clamped pattern and blanks carried thereby willnow be moved toward the pattern-controlled wheel of the rotating cutters 200, so that the parts will now be in the positions shown in 4 and 5, whereupon the latch bar 131 will have permitted the pulley 117 to be clutched to its operating shaft .and thereby impart motion to theworm shaft 82 and the blanlvcarrying shafts 83. At the same time the vertical feed screw 15 will have imparted downward movement to the apron 5 and consequently to the saddle 50 andthe parts carried thereby. l

The downward movement of the saddle 50 will carrythe pattern along the face of the pattern wheel 300 and also carry the blanks in like manner across the working .faces of the cutters 2,00 so that as the. saddle is lmoved in' and out in accordance with the action of the pattern on the pattern wheel 300 the series of rotating blanks will in passing down across the rotating cutters receive the contour of the pattern. This operation will go on Vuntil the latch 31 engages the stop 37 and releases the lever 29, which in turn separatesthe 'divided nut and renders the feed screw inoperative. At the same time Vthe saddle 50 will have reached its innermost yposition and the blanks formed into comonly necessary to turn the shaft 309 to raise or lower the 'tongue 308 as before described, so as to set the pattern Wheel closer to or farther from the pattern 61. These sizes of the heel are shown in Figs. -land 6 and the several sizes merge or vanish at 00. Grade may be added above and below this point 400 by giving the fan board a permanent angle by adjusting bolt 319 and then moving pivot bolt 325 outwardly in slot 324 of fan board lever 323.

While I have shown and described six pa ttern shafts and six cutters,-the number may be varied to suit, and so also there are many changes which may be made without departing from the-spirit of my invention. Furl thermore, articles other than woodenheels may be produced by this machine without making any radical changes in its construction.

In conclusion, Iwould add that great dificulty has been experienced in turning irregular articles, such as shoe lasts, true to shape and size, owing to the fact th'at the pattern and blanks are commonly carried'by a swinging frame pivoted at its upper end, which frame will, when the blanks are` presented to the cutters, be skewed out at its'lower free end and so cause the production of uneven work.

This is true also of a rocker-supported sliding frame. To overcome these objections I have made the apron 5 to overlap the sides of the column 1 and there provided the vertical raceways 64 containing the ball bearings 7 so that the apron is held to slide in a true vertical line without any'chance of its being moved or forcedoutwardly. It has a very free and easy movement, however. Furthermore, the saddle 50 is in like manner held to a true horizontal movement by its end edges overhanging the ends of the apron top, as yshown in Fig. 2, and connected thereto by the V-raceways containing the ball bearings.
