Be it known that I, I'IERMA'N A. Davenrolrr, a citizen of the United States, residing' at Brockton, in the county of Plymouth and State of Massachusetts; have invented certain new and useful In'iprbvcmcnts in Sole-Pressing Machines; and I do hereby declare the followin to be a full, clear, and exact description 0 the invention, such as .w ill enable others skilled in the art to which if appertains tomake and use the some.

'The present invention relates to solo pressing machines and more particularly to that class of sole pressing machines which comprises a shoe supporting jack and a sole pressingpad and which are used to per- 0 OPGIHUOII of laying the sole.

Sole laying machines as usually constructed comprise a single shoe supporting jack and a coiiperating sole pressing pad and thescimachines are usually operated in pairs, the/two machines being attended Lo by one workman and one machine being used to la the soles of right shoes and the other to ay the soles of left shoes. Sole laying machines have however, been de- ,vised comprising two shoe supportingjacks andtwo coiiperating sole pressing forms so that a singlemachine can be used for opera-' tion upon right and left shoes.

The object of the orcsent invention is to provide an improved sole laying machine adapted ,fior operationnpon right and left shoes'yvliich is simple and compact in constru ctmn and fficient in operation. and whicl| ,can be conveniently used b the operutorito lay the soles of either rig t or left .shoe as/ma be desired. h

lvith'this object in view the present invention consists in a sole laying machine having its various parts constructed and urran ed ;'as hereinafter described and elaime V Amachine cmbod ing the present invention i rits preferred form is illustrated in the accompanying drawings, in which Figure 1- is a view in rear elevation of the machine with a portion of one of the driving pulleys broken away to show underlying parts; Fig. 2 is a sectional plan View showing the mechanism in. the lower art of the machine; Fl .3 is a detail view illustrating in side is e'vation the" mechanism illustrated in Fig. 2 for actuating one of the shoe supporting jacksand 'sole pressing.

forms together with the shipping mechanism by which the mechanism for actuating both picks and forms thrown into operation; Fig. 4 is a detail view in side elevation illustratnig the autonmtic clutch actuating mechanism for throwing one of the driving shafts out of operation, and Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. 4.

The machine illustrated. in the drawings comprises two shoe supporting jacks, two sole pressing pads arranged to coiiperate respcctiwly therewith, a foot treadlc and connecting rod for moving each 'ack toward its cooperating pad to bring t c sole of the shoe supported on the pick into contact with the pad, and a separate shaft and connected mechanism for actuating each pad in force the pad toward the jack with suilicicnl pressure to properly lay the sole. Each jock and'its cooperating pad is constructed and arranged as in the well-known Goodyear sole laying machine and the mechanism for actuatiil each 'jack and form to bring the sole of the shoe into engagement. with the pad and to lay the sole is also the same as in that machine. The construction and arrangement of these parts and mechanism are clearly illustrated and described in the patent to Holland No. 362,447, dated May 3, 1887, in the 875,549,..duted Deccm or 27, 1887, and in up )licnnts prior patent No. 781,636, dated l e ruu'ry 7, 1905', and will, therefore, be only briefly described herein.

Each jack comprises a heel post 1 and a. toe post 2 adjustably secured upon a crosshead 3 which is mounted to reciprocate upon vertical guide rods' i. The rods 4 pro cct upwardl' from side standards 5 and are provide with collars 6 between which and the cross-head 3 coiled springs 7 ureinterposed. 'Ihcse springs normally hold the crosshcads elevated in the position indicated in Fig. '1 and return the cross-head to this position when they are released after being depressed. Each cross-howl is connected by a rod 8 to a foot trundle J, bymeans of which the cross-head is moved downwardly to bring the sole of the shoe into contact with the sole pressing pad.

10 indicates clut sh collars mounted to slide u on the rods 4 upon the cross-head 3, whic clutch collars-act to lock the crossheads in their depressed positions until re patent to HanmrNo.

leased by the operator, as is fully described in the patent to llannn and in applieants prior patent hcrcinbefore referred to.

The sole prcssim pads are indicated at 11 and are mounted in pad carriers 12 providcd with collars having a sliding engagement with the vertical rods 4. Each carrier 12 is pivotnlly connected to the upper arm of a toggle lever 13 which is actuated from an eccentric on a shaft l t 'ournaled in the lower portion of the SICl O standards 5, through an eccentric strap and link 15 and a link 16, the link 10 being provided with a guiding slot through winch the shaft 14 passes and the arran 'ement of the eccentric and links being shot that a complete rotation of the shaft 14 raises and lowers the carrier 12 and the pad supported therein. Each shaft has secured thereto a gear 17 which meshes with a pinion 18 upon a driving shaft 19. The drlvin shafts 19 are arran ed parallel with t'tlCTl other and each sha t is provided at its rear end with a driving pul cy 20 mounted to rotate loosely thereon. A friction clutch is provided for clutchin each drivin )ulley to its shaft, the clutc i-being of we 1- nown construction and being actuated to clutch the pulley to the shaft by a pivoted lever 21. The lever 21 extends into the path of movement of a collar 22 monhted to rotate with and move longitudinally on the driving "shaft. The collar 22 is provided wit-ha groove which is en aged by a pin rejecting from the upper on of the pivote lever 23. The lower end of the lever 23 is provided with a pin which when the collar 22 is moved to actuate the clutch is brought into the pathof movement of two pins 24 located at diametrically opposite points on a collar 25 mounted on t e shaft 14 and connected thereto by means of asprin'g so as to have a sh ht rotary movement independent of the she as illustrated and described in the patent to Holland above referred to. i

The shafts l9 and the mechanism driven thereby are entirely independent of each other, so that after the driving alloys are clutched to the shafts the two so e pressing pads are operated independently and the shafts are :uit'oma'tically thrown out of operation independently. In order to enable the movements ofboth sole ressing pads to be conveniently controlled 1y the operator clever 26 is provided the upper end of which is located between the shoe supporting jacks in coi'ivenicnt )osition to be gras ed by the operator ant. the lower end of w iich is pivotall y mounted upon a standard 27 pro ectin r upwardly from the base of the machine between the driving shafts 19. The lever 26 is providrd with a cross bar 28 from the ends of whirl pins project into a position to engage the ipprr ends 0 the lovers 23. The lever 20 is normally held above suggested it is merely necessar in the position indicated in Figs. 2 and 3 by means of a coiled spring 29 connecting the cross-bar 28 with the base of the machine. When the lever is in this position the pins on the ends of the cross-bar 28 permit the clutch operating collars 22 to move to the position indicated in Fi 2, in which position of the collars the riving pulleys are disconnected from the driving shaft. A rearward movement of the lever 26'by the operator moves both clutch pollars simultaneous] and connects both driving pulleys to their shafts so that the actuating mechanism of both sole pressing pads is thrown into operation. A single movement of the lever 26 thus throws the actuating mechanism of both sole pressing pads into operation and both mechanisms are caused to operate simultaneously.

Each mechanism is autometically thrown out of operation after the shaftht and-the eccentric thereon has made *4). half rev lution,,so that; each pad is stopped alternagely in its highest and in its lowest position. he mechanisms may be arranged to raise b0 11 pads simultaneously so that the soles of t e" shoes on both jacks are brought under pressure at the same time. Preferably, however,

the mechanisms are so arranged that one pad is stopped in its lowest position whenthe other is sto pod in its hi best position, the sole'tof the s cc on one jae being under pressure when the sole of the shoe on the other jack is relieved of pressure. To cause the machine to operate in either of the-wag more one of the levers 23 by hand wit out moving the other lever, so that only one driving shaft 19 is' thrown-into operation and the shaft 14 connected thereto is caused to make a half revolution while the other shaft 14 remains stationary. Both driving. pulleys20 may be conveniently driven by a single belt 3,0, which belt passes over the pulleys in the same direct-ion and over an idler pulle 31. The pulley 31 is journaled on a stu projecting from a block 32 mounted in'a vertical guide-way on the standard 27 and resting upon the upper end of a screw 33, by' means of which the block 32 and pulley 31 may be ad'usted to tighten the belt 30 as may be desired The invention having been thus described, what is claimed is: 1
