Like characters of reference refer to similar parts throughout the different views of the drawings.
Mounted on a pedestal 1 and secured thereto by bolts 2, 2, is a column 8. Interposed between the pedestal and column and using the same securing bolts, is a knee 4. In bearings 5, 5 is journalled an oscillating shaft 6, upon which is loosely mounted a segmental gear 7. In the bearing 8 on the column (3) and the bearing 9 on the knee (4) reciprocates a shaft or spindle 10. Out on this spindle is a rack 11, adapted to engage the segmental gear 7 The lever 12 is the means through which the gear and spindle'are actuated. Fixed to the spindle is an arm 13 with means 011 the inner side for attachinga chain or cable to operate the counter-weight 14. On the outer end of this arm is an adjustably secured plunger 15 with the lower end slightly knurled, as at 15*. On the forward side of the spindle (10) is adjustably secured a bar 16, with its lower end beveled, as at 16*. The purpose of this bar will be hereinafter explained. On the outer end of the knee 4 is formed a saddle 17 in which actuates the slide 18.
Referring to Fig. 3, the slide 18 carries on its inner end a roll 19 which is mounted in an adjustable block 20. Centrally of the slide is a projection 21 extending upwardly from'the slide a spaced distance. Attached to the sides of this project-ion are resilient bars 22, 22, which extending upwardly and made into the proper form constitute the support for the shoe being turned.
Directly beneath the projection 21, and in alignment therewith, is another projection 23. The two projections are bored to pro vide a bearing for the locating plunger 24. Toward the inner end of the slide is still another downwardly disposed projection 25, in which is rigidly secured the shaft 26. Mounted on this shaft (26) and sliding freely thereon is a latch carrier 27, and in an off-set portion 27 is an adjustable bushing 28. This bushing is located in alignment with the bearing extending through projections 21 and 23 and is adapted to slidably recg lve the lower end of t e locating plunger A threaded collar 29 adjusts the plunger 24 vertically. Interposed between the bushing 28 and the collar 29 is a helical spring 30 and on the extreme end of the plunger 24 is a nut 31.
Secured to the projection 23 is a stud 32 extending outwardly through the saddle and the spring tensioning bushing 33. A nut 34, outside of this bushing, acts as a stop to control and adjust the inward movement of the slide 18. A spring pocketed in a bored portion of the saddle and thrusting against the bushing 33 and the projection 23 forces the slide toward the spindle 10, the nut 34 impinging on the bushing 33 with the slide in its extreme inward position.
The latch carrier 27 has a rearward off-set portion 27 in which is an oblong hole 36. The spindle 10 extends downwardly through this hole and terminates in a reduced portion or a stud 37, the latter carrying a nut 38. Slidably mounted over this stud (37), and above the nut 38, is an angular connecting bar 39, pivotally connected to the foot pedal 40, the latter being fulcrumed at 41 on the pedestal 1 and carries an adjusting stop screw 42 on its forward end.
By observing Fig. 7 it will be seen that the projection 25 carries a latch 43, secured to the rod 44, and extending downwardly hooks on to the latch plate 45,the latter secured to the carrier 27. Extending rearwardly, this rod (44) has a bearing at 46 on the knee 4. liilounted fixedly on and near the end of the rod 44 is an arm 47 carrying a stop screw 48. A spring 49 normally holds the latch 43 in locked position.
Referring to Figs. 5 and 8, 50 is a latch having its upper portion 5O bent at an angle and made into the form of a ring which encircles the spindle 10. This latch (50) is pivotally hung on the off-set portion 27 of the latch carrier 27 and engages, at the proper time, the latch plate 51 sunk into a depression in the spindle 10. A screw 52 is for the purpose of disengaging the latch (50) from the latch plate on the upward movement of the carrier. A spring keeps the latch normally against the spindle 10). In Figs. 17 and 18 I have shown the parts having to do with the actuation of the turner. Outside of the right hand bearing 5 is a hand lever 12, preferably atljustalaly clamped to the shaft 6. Between the bear ings and on the shaft 6, I loosely mount the segmental gear 7. Adjacent to the gear and securely fixed on the shaft (6) is a flanged hub 55 having an arcuate hole through the flange thereof to receive the pin 56 which is fixed in the gear 7. Secured adjustably to the hub 55 is a segment of a disc 56 with the outer periphery having one edge beveled. In alignment with the face of this disc is a plunger 57, reciprocable a bearing 58 llu Cal
formed on the-innerjsideot the columns.
On the lower side' of the lever 12 lattach, over the rod 59, a counter-w'eight "60, the purpose of which will'shortly he described. As I'stated in my preamble, I use onthis shoe turner one element 'ofa inach'i'ne already patented by me. This element isthe Supporting member 61, shown in section in Figs. 12, 13, 14 and 15, and in t'ull i'n Figs; 1 a-nd'2. Briefly, it consists of resilient arms extending upwardly from rigidly *s'e'cu'red lowerextremities, and ter'niinat'es'a't the'to'p in reversed U shaped"cla'1n1')s, onedispose'd Within th'eother with their o 'v'e'n' side's facing and forming together an expansihle tubular structurethrough which the shoe is forced downwardly 21's it is turned. Ihave somewhat improved this element inone' pa rticular,i"iainelythe inatter of deereasing'the friction of the "sole as it isbent over the top of the support While being "forced do'w' n into the'latte'r. An "einbodin'ie'ntot' this idea is illustrated in Figs. 19 and 20, in which is shown small rolls 62, '62 rotatable over pins 62-3, "63,a roll loeing 'inountedoneiich "of the nien'ibers ofthe s'uppo'rt.
T he Construction of the upper end of the locatii'ig 'plunge1-"2tis'seenin Figs. 9 and 10. The plunger is -'b'ifur sate 1 at the extreme upper end end within the hiiii'ircatio'ns 24,
2 1: is a roll 6%, preferably bnt no't necessarily covered by some slightly resilient substance, such-as rubber-oifahric, to eliminate the possibility ofinarrin g the (it'ltel' ''ulfwe "or the sole and also to prevejntthe slipping of the sole on the 'roll'were it 'too'slnoothand frictionless. A recess 65 is c'ut'i-ntheside of the roll and a flat spring 66, which issecu'red in a slot '67 in a'pl'u g 68insei'ted'in allele in the plunger, enters and h'olds'the roll normally against a stop scre'wGS) o1'3er'atingin an arcuate cut-away portion 70011 the end of theroll. 'IFn locating a shoe-over this rollthe aetiono't the upper plun'gerfWhen it is being aligned with the shoe support, "tends to turn this roll until the opposite end of the slot '70 impinges 'on t'he'screw 69. This rolling actiongreatly facilitates the initial turn over of the tip of the 'sole.
In Figs. 11 and 11 'I'ill'ustrate"alternate designs for this .roll. In the former the side is cut down leaving a shoulder 71 against which the tip'ol? the sole 'n'i'ay seat. in the latter I flatten that portion, 72, Whioh'th'e rolling action, incident to the locating foperation, will eventuallybring to'the top central line,,-or directly in line'i vith the upper plunger,'a'nd the sole, seated on this 'fla'ttened surface Will assist in keeping the roll steady and tree from Wobhlin'g as it procecds (flounward through the 'supp'ort.
In describing the operation er this inachine it will first be "well to state tha t the latch carrier 27 placed in'a position "as seen in Figs. 1,2 and 3,'-the'-latch holding the carrier, temporarily in this loelted position. 7 The latch 50 'is {not as yet functieni 1 1 g,t'1nere1 lflngegaifist the sideot the spindle 10. The'position or the hand leyer 1 2 is as shown in full lines in Fig. 1. r N oiy'the first move is'to place a l-unturned shoe over the'flocatin-g plunger 24 (see Fig. 12) The 'foot pedal is next brought into actionand is forced downwardly until 'it comes x'vithin a spaced distance of'ebutting on the base "otthe ina'ohiiie. The upper plunger snow in a position as seen in Fi'g. l3,-the' two 'pluiigers being out of align merit, the 'be'v'eled'portion 162016 the bar 16 just contacting with the roll "19 "and the,

At-th'is 'ti'ineth'e latch 50 has loelted 'iiito the spindle 10, the-spirit; 3O put tinde'r "a slight compression, iyh'i'c'h "inay, be varied to suit the particular yvor'k in hand, the hand lever 12 carried down i nto' position 12 (see Fig. 1) an'd'theseginental disc "56 moved into Close Contact with the'pl uiiger 57; butt'he la-t'h carijieris still in locked pOsitioi1-,pre\ eiiting, "temporarily, fi'ir 'ther movement downwardly oft-he plungers.
'Byj're terenc-e*tofFig. '18 i'tfwill he seen that the lever 12 is in liked *r-eraudnship to are both secured to the shaft 6,"a'iid" zilso it Will he observed that the pin 56, fixed in the gear 7, occupies a; "positionin the forwardend of the "arc'iiate'slot '55, \i li ich'l'ocates the "lever in a position indicated hy 12. Fig. '1 and Fig. 18', after the full stroke of the foot pedal is inade. .And in connection with the foregoing;- i will stated; the object or and reason for: pl hcin 'g "the counter- Weight on the hand lever is to norial ly' hold tlic 'foi'wai'tl end or this slot aiiist the pin 56, the slot (55) 1')ro"."id1n,- "the means tor a slight movement of the httnd arm a? and tripping the latch l3. By this time the upper or opposite end of the arouate slot will have contacted with the pin 56 which will again start movement of the gear 7, the spindle 10, the latch carrier 27 and of course the two plungers 15 and 24, betweenwhich thesole of the shoe is held by the strong, yielding grip of the plungers and is carried downward through the shoe support 61 until the shoe has been completely turned. After the proper length of stroke to properly turn the shoe is determined the stop collar 73 may be adjusted on the spindle 10, so that further action downwardly of the plungers will not be made.
After the completion of the foot pedal stroke and the hand lever is being operated, the stud 37 telescopes the connecting bar 239. The hand lever is used for the entire return stroke andthe plungers retain their grip on the sole during'the entire turning and can pelling operations. l Vhen the lever arrives )aclr at the 12 position the tripping and locking of the latches takes place as when on the downward stroke,only in the re verse order.
One point I wish to emphasize, in conclud ing, concerns the functioning of the plunger 15 in turning the tip of the sole over the end of the plunger 24. The vcontacting points are wholly on the sole and not the upper and it remains thus throughout the whole turning operation.
