Another fautore oi the invention contemplates pro- -1.05 Viding n solo pressing machine comprising last and forni carriers. n.' crank shaft and suitahle connections between-the crank glmiit and the carriers, with mansii l l i l i under the control of the operator for throwing the crank shalt out ot operation when the lasty rear-hes a position ol presentation. ln the illustrated embodiment ot' this feature ol my invention, hereinafter deseribed` l have provided ineohanisin under the von trol of the operator for connor-ting and disrouner-ting the crank shaft and a soun-e ol power and have provided a earn, driven from the crank shaft and arting,y on said mechanism to prevent the crank shaft from being disconnected from the source oi power u ntil the last reaches its position ot' pr sentation. This i'ner-hanism in combination with the cam lor delaying its operative action until the last. reaches its position of presentation I believe to be broadly new and I therefore consider a. feature oi niyinvention to tfonsist in providing means under the control oi the rperator for throwing the actuating Ineehanism of the last and torni rarriers oi a rolling pressure sole pressing machine out of operation and means -or delaying the operative action oi such means until the last reaches its position'oi presentation.

In rolling pressure sole pressing maohines usually Constructed the last and form are'so actuated that the pressure proeeeds longitiulinally of the sole of the shoe iirst from the heel towards the toe and then from the toe tewarjls the heel` rlhis mode of operation tends to crowd the material of the sole towards the toe and heel and tmstretch the sole longitudinally. As a resuit'. thel sole of the shoe is often distorted sutlieiently to injure the shoe or even to burst the seam by which the sole is secured to the upper. i

One of the objects oi the present invention is to provide a sole pressing inarrhine whioh will operate to l-iress the sole of a shoe without displaeing the material ot the solo or stretch the sole sul'iiciently to injure the shoe and with this object in view, a feature ol theinvention Contenn'ilates providing a sole pressing,T inarhine oomprising torni and last; oarriers with mechanism [or actuating said earrier's which ants to draw the forni over the solo while in 4rontaet; therewith and preferably in the opposite direction to that. in whirh the pressure is proeeediug. ,ily so aetuatiug the carriers the displnring oi the material ol the solo is prevented and the solo is not streit-hed longitudinally to any appror-iable extent. This feature oi the invention broadly considered n'iny he embodied in any rolling pressure solo pressing machine as `lV believe that l am the tirst in the art to pro vide a. rolling pressure solo pressing maehiue f-oinprising a shoe supporting last and a solo pressing iorm in.

which the torni is drawn over tho solo duringr the pressing operation.

Rolling pressure solo pressing |na -hinos as usually r-onstrufted are provided With two shoe supportingr lasts and two r-or'iporatingg solo pressing; t'ornls and one oi the objorts ol' tho present invention is to providea mar-bine ol` improved vonstruf-tion and modo ol' opera- 4tion ('olnr'n'isintr two shoe supporting lasts and two ro oporatim,r solo pressing' lormsA and more partir-ularly snrh a 'mar'hino iu whir'h'tho numlu-r ol pressing op- @rationsl to rrhh-h tho soirl` ol' n. shoe supported upon oitln'rr last is subjor'lodr-an be varied at tbewill oi the operator.

For actuating'each last carrier and its cooperating form carrier a separate mechanism is provided, each oi which mechanisms ',eornprises a crank shaft lti. The

'v inner ends of the crank shafts 1G are journalr'd in bear- 'son ings in the web 11 and the outer ends of the shafts are journaled in 'the Castings 9 as is clearly illustrated in Figs. 3 and 4. The shafts are arranged in alinement With e'aeh other but rotate independently. Ear-h crankshaft is provided with a crank 17 whieh is onneeted by a link 18 to one of the last Carriers. lar'h last carrer is thus connected to its crank shaft by a link connection so that during Aa single revolution ol" the crank shaft the last carrier is oscillated backwards and forwards. In order to cause the torni carriers to be oscillated in timed relation with the last carriers, each last carrier and its coper'atin7 form carrier are ron- Ileeted by a link 19, thel lower end of the link being pivotally connected to the last carrier by' the pivot piniilhich connects the earrier to the link v18 and theupper end of the link 19 being pivotally connecterl to the form carrier on the opposite side of the pivotal center of the carrier. Both the last carriers and the form carriers are thus 'connected by means ol links to the cranks of the crank shafts 1:6, the last carriers being direetly connected by the links 18 and the lorm carriers being connected by the links 18, the last carv riers ai1d`the,1inks 19. The oscillating movements which are imparted to the last and form carriers from lthe crank shafts are, therefore, certain and accurate and any relative movement'. of the lasts and forms when the Carriers sWiI-ig by thelinev joiningr the pivotal centers of the :carriers which would tend to injure the shoe is prevented.

*y The relativeiangular positions of the pivotal nonnen. tions of the linfks 18 and 19 with thelast and form carriers and the ldistances of these pivotal. connections from the pivot! l centers oi' the carriers, are such, that` when a form ,arrier is osoillated from a last: carrier through a-conneoting link 19 the surface of the form in contactwith the sole travels faster than the surface of the sole, so that the form is drawn over the sole during' the pressing operation in the opposite direction to that in which the pressure is proc'zeeding. As a result 'o'futhis drawing action of the form, the displacing of the material which would otherwise take place is pre-v *vented and the sole ispressed 'without any liability of' injury to the shoe or any appreciable stretching of the sole longitudinally. i i links- ]9 are connected to the form carriers is clearly The manner in which the illustrated in Figs. 5and G. As shown in these figures,

the upper end of the link l.) illust-rated provided -'With a Cylindrical hearingwheh engages a sleeve 20 the formduring the movements-ol' the carriers in both tion by turning up the nuts which secure the stud. in

the carrier ily so rotating thel sleeve, the upper end ol" the link is moved towards or from the pivotal center of the rarrier, and thus the amount ol' the drawing 75 movement which is imparted to the torni is adjusted as desired. v l

Each crank shaft l is provided with a worin gear 25 whirh is engaged by a worm 2t; u pon n shaft 27 jour naled in bearings in a eastiilg 9. Itavh shaft 27 is pro- 8() vided at its rear vond with a i'rietional vlutch member 25% sel-ured to the shaft and with a driving pulley 29 mounted to 'rotate loosely on the shalt. The driving pulleys are provided` with trie-tional surlaees to engage the rietional clutch members 28 and ine-ans are provided for moving the pulleys longitudinally et the shafts 27 ind @pen dently of each other so that each shalt 27`and the crank shaft geared thereto van be driven separately. Both pulleys 29 are rotated constantly by means of a Single driving belt 30 which passes over the 90 pulleys and over an intermediate idler pulley 3l mounted upon a stud secured in the bracket l0. lhe driving pulleys are moved into and out of 4engageinent y with their clutch members and their movements are controlled by means which are substantially duplicates@AA oi each other, and in the folle-wing description I haye accordingly referred to the moans for moving.; but one pulley longitudinally oi' its shalt and for .f-ontrolling its movements, it being understood that except its otliler- Wise specified the parts referred toare duplieated on lofi' opposite sides ol the machine. 'y

The driving pulley 29 at the right hand sidelo the machine in rigidly secured toa sleeve providedlwith a groove which is engaged bystuds projerting from the forked upperl end ot' one arm o a lover 33 loosely 105 pivoted upon a sha t 34 extending across thi;I rear ol the machine andjournaled in bearings in the castings 9.

The other armof the lever 33 is connected by an adjustable link 35 te the rear end oi a leverl 36,1110 oonstruetion and arrangement of the levers 33 and 236i and the 110 link 35 being such that when the rear end oi the` leverv 36 is raised the pulley 29 is moved into eiigagei'nent with the clutch In einher 2S and when the rear endloi' the lever 3G is depressed the pulley ismoved out til-engagement with the rlutehmember. The rear end of the lever 36 115 is provided with an anti-friction roll which is ongaged by a cam 37 Secured to the rear end ol a rock shalt 3S journaled in hearings in a casting 9 and in a bracket secured to one of the front standards of the machine frame.y To the front end ol the shaft 38 atreadlo lever 120 39 is secured .by mea-:ns of which the shalt- 38 and cam 37 secured thereto can be 'rocked by the operator. The'shape of the cam 37 is such that when the treadle 39 is depressed by the operator the high part of the' cam is raused to engage the anti-friction roll-ol the 125 lever 3G and raise the rear end of the'lever, thereby actuating the 'lever 33 to move the pulley 29 into envgagement with the clutch member 28. The pulley tion, therefore, a drawing movement is imparted to remains locked in engagement with the elutch member until the'c'arn 37 is oseillated in the opposite direction. 130

frame and the upper end of the arm 55 is connected to one of the front standards of the machine frame by means of a coiled spring (S0. A spring Gl is coiled around the rod 52 and bears at its upper end against the blockl o3 and at its lower end against a collar 62 secured to the rod. When the form carrier is in tho position illustrated in Fig. 7 with the last in its position of presentation, the arm 55 is held in the position illustrated hy means of the chain 59, the spring 60 boing stretched and the rod 52 being held in its raised position by the cngzigomcnt oi the roll 57 with the c am plate 58. As the form carrier swings rearwardly the spring G0 swings the arm 55 about its pivot and the" spring 61 lowers the rod 52 until the clump 5l is i'noughl. into Contact with the solo of the shoe, the dowi'iward movement taking place as the roll 57 travels along the cam plate 58.

the sole during the continued rearward movement oi the last carrier and also during the return forward movement oi the last carrier until the chain 59 is again tightened. As the carrier swings to its position at the front of the machine the arm 55 is swung about its pivot against the tension of spring (il) and the loll 57 is caused.

to travel along the c am plate 58, thereby returning the 'clamp to the position illustrated in Fig. 7'. "lhe b'nt portion of thevrod 52 between the blocks 53 and 54 causes an additional rearward movement of the clamp during its upward movement and -a corresponding additional forward movement during its downward movement, these additiontl movements being suilicient to cause the clamp to be actuated atthe desired times during the movements of the last and. form carriers without contacting with the lorm.\ The block 56 has a limited swinging movement with relation to the block 56il and rod 52, being swung into a position in line with the rod 52 when the chain 59 is 'tightened and being swung into a positioninclined to the rod 'when the chain 59 is slack. An initial upward movement is thus imparted to the rod 52 to raise the clamp 51 fromthe sole before thearm 55 is swun'g to move the clamp away from the last'han'd a tina-l downward movement to press the clamp against the sole after the clamp has been inserted-between the last and form.'

The operation of the machine above 'described has been sufiiciently indicated in connection withthe description "of the construction and arrangement of the various parts al'id will be readily understood by those .skilled in the art without a separate description thereof. Having thusiindieated the nature and scope of' my 'invention and having speeically described a machine embodying the various features thereof in theirJl proferrcd form, I claim as new and desire to secure by Letters Putcnt of the United States: l
