pertains to make and use the same,

The present invention relates to sole pressing pans for sole laying machines.

lhe sole pressing pad now commonly used in sole laying machines is composed of yieldingelastic material, such "as soft rubber, and is usually supported in a movable holder constructed tocause the pressure exerted by the pad to be distributed as evenly as possible over all portions of the sole of the shoe. lt is desirablein laying the sole that the ed esof the shank and forepart, and particiil rly of the shank, be rounded over so as to fit snugly against the last. When, however, a pad of yielding elastic material such as is now commonly used is forced against the sole with sufiicient pressure to embed the sole in the pad so as to round over the edges of the shank andforepart, the heel portion of the sole is also embedded in the pad and the edge of the heel portion of the sole or the heel seat is also rounded over. This is objectionable, as the heel seat should be substantially fiat to enable the heel to be properly attached to the shoe, and when the edge of the heel seat is turned up during the la ing operation much difiiculty is experience close fit between the edges of the heel seat and the heel. i r

The principalobject of the present invention is to provide a sole pressin pad which will exert the proper amount 0 pres sure upon all portions of the sole to properly lay the sole and round over the edges of the shank and torepart if desired, and at the same time leave. the heel seat substan tially flat. v I

Other objects ofthe invention are to provide a sole pressing, ,pad of yielding elastic material which Wi'llireadily conform to the shape. of the bottom of the last and at the same time be strong and durable so as not to be easily cut or injured by theedges of the shoe sole, and in general to improve the con- Specification of Letters Patent.

SOLE-PRESSING PAD.

vision of asole pressing pad having a 'tore part of yielding elasticmaterial and a heel part of substantially harder material than By forming the heel part of harder material than the forepart the heel portion of the sole is not embedded into the pad and the amount of pressure to properly lay the sole can be secured without liability of turning over the edge of the heel seat. The heel portion of the pad is preferably of yielding elastic material in order that it may yield sutlicicntly to enable the pressure to be properly distributed over all portirn'u: of the sole and prevent the formation of a ridge upon the sole by the action of the two portions of the pad thereon.

The invention contemplates the use of any suitable material, but the material which has been found to be most satisfactory in tt' tual practice is rubber, the forepart of tin: pad being of softrubber and the heel part of the pad being of substantially harder rubber. The two portions of the pad. may be constructed and arranged in any desired manner but are preferably secured together so as to form. an integral continuous pad, When the pad 15 composed of rubber itmay be made by any one of a number of different methods which will suggest then'iselves to manufacturers of rubber goods. A COTWBI1- ient method of making the pad of rubber consists in varying the proportions oi theingredicnts forming the two parts of the pad and subd'ecting the entire pad to heat so as to 'prouce a continuous integral pad of vulcanized rubber.

In the preferred form of the invention the heelpart of the pad is-of yielding elastic material, and in order that the heel part may yield sutficiently to properly distribute t 'e pressure over the entire sole without any l ability of turning over the edge of the heel seat, the heel part of the pad is preferably shaped to bear against the sole of the shoe inside of the edge of the heel seat, the heel part of the pad presenting a raised surface somewhat smaller then the heel seat of the sole to be operated upon. This construction of the heel part of the pad may also be used.

to advantage in sole pressing pads in which both theheel part and the torepart of the tions of the pad than in the remaining pad are composed of the same kind of material, and it is accordingly considered that a feature of the resent-invention consists 1n s ha ing the hedl part of a sole pressing pad so t .at it bears against the-sole-of a shoe 1nside of the edge of'tlfe heel seat whether or not the heel part ofithe pad is composed of harder material than the forepart. I

It is also considered that a feature of the present invention consists in the provision of a sole ressing pad of yielding elastic material su stantially harder in certain poror tions as it will be obvious to those ski eid in the art that similar or. desirable results might be secured. upon portions of the sole other than the heel seat by forming the parts of the pad acting upon said portions of harder material.

The working face of a sole pressing pad composed of yielding elastic material such as rubber is easily out or injured by contact with the edges of a shoe sole, and in order to protect the working face of the pad and at the same time allow the pad to readily conform to the s ape of the last, a feature of the their resentgihve'ntion contemplates the prov'sio kxof a leather covering molded to the sh e f the working-face of the pad. By mmld' the leather covering before it is applied f the ad, theoovering accurately fits tlfe pad ;an does not imp r its yielding elastie qualities. r

In additio 'ito the features of inventionabove referre to the present invention also consists in the'oonstructions and combinations hereinafter described and claimed, the advantages of which will be obvious to' those skilled in the art.

The several features of the resent invention will be'clearly understoo from an inspection of the accompanying drawings, in which I i Figure is a view in side elevation of a sole pressing pad embodying the same in referre of We l-knownconstruption; Fig. 2 is a c tral longitudinal section of the pad; Fig. 3 is a plan view of the pad; Fig. 4. is a crosssection taken on the line 4-4-. of Fig. 2; and Fig. 5 is a perspective view of the pad" with the leather covering removed.-

The pad holder illustrated in Fig. 1 is the holder which is used in the well-known Goodyear sole laying machine and may be briefly described as follows: 1, 2, 3- and 4: in-

- dicate supports to which thepad is secured.

These supports are mounted so as to be capable of tilting in any direction upon the upper ends of vertical slides 5, 6, 7- and 8 mounted in a block 9. The two middle supports 2 and 3 are mounted directly upo the upper ends of the slides 6 and 7, while the supports 1 and l are secured to blocks mounted upon the upper ends of the slides form supported in a holder 5, 5nd 8 so as to be capable of adjustment to accommodate pads oi; different sizes. The slides 5 and 6 are provided with pins which engage slots in opposite ends of lovers 10 and the slides 7 and 8 are provided with pins which engage slots in opposite ends of levers 11. The ivots of the levers l0 and 11 are received in slots in opposite ends of levers l2 pivotally mounted upon ears l3 projecting upwardly from. the base of the block 9. The levers 10, ll andl2 act as pressure distributing devices sothat the pressure exerted by the pad is distributed evenl over the sole. The block 9 is provided with guiding rods 14.- extending downwardly therefrom through the bottom of abox 15 in which the block 9 and the parts supported thereby are laced. The block 9 .is yieldingly supporte in the box 15 by means of coiled'springs l6 and the upward movement of the block is limited by the heads 17 on the lower ends of the rods. The box 15 is pivotally supported in the sole pressing machine by means of studs extending laterally from projections on the side of the box, one of these studs being indicated at 18 in dotted lines. The box 15 is thus allowed toswing about the axis of the studs 18 as a pivot and thus aid in distributing the pressure equally orer the sole of a shoe. The sole pressingpad comprises a forepart 19 of soft rubber and a heel part 20 of harder rubber, these arts, as illustratedin the drawing, being 0 osel united so as to form a continuous lnte'grai ad. The working face of the forepart of t e pad is shaped to properly press the forepart and shank of the sole of a shoe. The heel part is shaped so as to present a raised surface 21 similar in shape to the heel seat' of the sole but smaller so as to bear against the sole inside of the edge of the heel seat. The positions of the several parts of the pad with relation to the sole of a shoewill be apparent from an inspection of Fig. 3, in which a sole is indicated at 22 in dotted lines. The covering for the pad is indicated at 23, and consists of a sheet of solo leather molded to the shape of the working faces of the heel part and forepart of the pad and attached thereto by cement or in any othersuitable manner. The nature and scope of the present invcntion having been indicated, and the preferred form of the invention havin specifically described, what is claime is 1.
