Specification of Letters Patent.
Patented Dec. 21, 1915.
Application filed November 3, 1911. Serial No. 658,293. p l
To all whom it may concern Be it known that I, CHAUNCEY I a citizen of the United States, residing at Newburyport, in the county of` Essex and lappertains to State of Massachusetts, have invented cer'- tain new and useful Improvements in Sole- Pressing Machines; and l do hereby. declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to 'which it make'and use the same. The present invention relates to sole pressing machines, and more particularly to machines of this type which are employed for molding the shanks of soles which have been incorporated in boots and shoes.
In the manufacture of all types of boots and shoes, it is desirable to secure arounded shank, as this type of shank has several advantages, some of which are that it adds to the finish and appearance of the shoe sole and greatly stiiiens the sole against longitudinal bending at the shank.
This latter feature `is particularly advantageous in turn shoes, as shoes of this typek lare necessarilyv of a light construction and have a tendency to become bent and cracked at the shank during the manufacture of the shoe. With existing machines for operating upon shoe soles and with the ordinary methods of manufacture at present in use, it is not pos sible to secure the requisite curvature of the shank portion of the sole owing to the fact that the lasts upon which the shoes are made and which are retained in the shoes during the manufacture are of .such a construction that the pressing device, whether .it be a pressing form or a roll will strike and mar the vamp of the shoe if it is constructed with a sufficiently great curvature to impart the` .desired transverse curvature to the shank of the sole. l
The object of the present invention is to secure a rm rounded shank having a greater transverse curvature than can be secured upon the ordinary last without marring the upper or otherwise spoiling the iinished appearance of the shoe or breaking the inseam fastenings-which 'secure lthe upper lto the sole.
Vith this object inview, 'one feature of the invention contemplates the provision of anxincomplete supporting member arranged to extend forward only throughout the shank ofthe shoe, and a cooperating pressure l represents a side elevation of a ing member which is arranged to operate ported by the first mentioned member.
i A further feature of the invention consists in the provision of a shoe supporting member whichy is narrower than the last of the shoe to allow the upper to hang down freely upon' both sides, and a cooperating sole pressing member provided with a pressing face having a greater transversevcurvature than the angle of the `vamp in the finished sioe.
A still further feature of the invention comprises a pressing member having a transversely curved pressing face arranged to engage with opposite margins of the sole simultaneously, and a cooperating member for supporting the shoe at the shank inside of the inseam in order to maintain the fastenings which secure the upper to the sole unbroken during the pressing operation.
Still further. features o-f the invention consist of certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be apparent to those skilled in the art from the following description. p
yIn the accompanying drawings illustrating the preferred form of the invention Figmachine embodying the several features of the invention in their preferred forms, and shown with the supporting form arranged in an inoperative position; Fig. 2 is a side elevation, partly in. section, of the machine showing the shoe supporting form and various cooperating elements in an operative position; Fig. 3 is a lfro-nt elevation of the machine; Fig. 4t is a section upon the line 4 4 of Fig. 2, looking in the direction of the arrow; and Fig. 5 is a cross section of the shoe supporting member and leveling yroll cooperating therewith and showing the manner in which a shoe is supported upon the form and the operation of the roll thereon. v
Substantially all welt and turn shoes are strengthened at the shank by the addition of a shank stiffener, and the rounding of the shank transversely not only aids the shank lsti'ener in strengthening the sole, but at the same time seats the shank stiffener more securely in its position. It vwill be readily understood by those skilled in the art that soV the rounding of the sole has the same effect upon the longitudinal bending of the Isuole that the ribbingy o-r flanging of' a thin uflat plate has upon the resistance to bending' of that plate. Turn and Welt shoes are 1nanu` factured upon a Wooden-last Which remains in the shoe until thewupper and sole are permanently securedtogether. In order to secure the requisite strength in cross section of the last and to properly fill out the vamp of the shoe, it is necessary for the last to be' fairly Hat at the: portion which supports'the n shank land that the body portion of the 'last which supports the vamp have a certain `in` c'lination relativelytc the bottom of the last. The angle Which this portion of the' last makes with' the bottom ofthe last may be conveniently designated as" the angle' ofthe vampiri the nished shoe. Y
Y The present machine operates' upon the shoe when o the last and theshank molding operation takes place at any convenientperiod'in the manufacture of theshoe: The
lshoe is supported upon a form which is narrower than the last of the' shoe to allow the rupper to hang down loosely upon both sides 'of the form Without interfering With the operation of the pressing member, there"- by avoidingany danger of the pressing member striking and ma'rring` the' upper during the molding of the shank. f
In the illustrated embodiment of the in-v vention, the' shoe is supported by a form indicated at l, which cooperates with a lev-v eling roll indicated at Q, to mold the shank of the shoe. The formafnd roll are pro! lvided With pressing surfaces 3 and L respectively, which are curved transversely to impart' the proper' shapeto thev shan-k, andV the transverse curvature ofthe pressing face l is greater than the angle of the vamp in the ii'nished sh'oeiylnjordier to maintain thel inseam fastenings unbroken during the pressing operation,=:the forni I is arranged to support the shoe at theishanlr inside of the inseam vso that the` opposite margins'v o-fl the sole are free to; be presseddovvn-Wardly by the leveling'roll- 2. is the' form carrying the shoe is moved into a pressure pro'- ducing position, the surfaceA of the' rollen- ,Y
gagesv with' opposite"y margins lof the'l sole v Iand presses them downwardly until the en'- tire Width of they shank at the line of pres'- sure of the leveling rolly conforms exactly tox the curvature ofthe pressing faced'.
The' shoe supporting form is normallyretained by gravity in an inoperative position or a position of presenta-'t'iorii as it may be terrn'ed, which is' removed frointhev levelingv roll and' conveniently accessible' to= the operatorl for the putting on'of a new shoe or' theremoval ofva finished one'. The form isl movedinto position beneath' the' ro'll by mechanism underthe control of the opera-f tor and by' varying the pressure upon a suitablecontrol pedal any desiredpressure can be secured upon the shoe. The form eX- tends forward yonly throughout the shank of the shoe and the shoe is., clamped to the .forni during the leveling operation by a heel clamp which operates automatically upon the movement of the forminto posi-c` tion beneath the roll. The roll is freely rotatable and is eontinuously moved back and forth to'cause the roll to traverse longitudi! n nally of the shank. The extent ofV this movement may be varied to; accommodate the machine' :for different length-'Shanks throughtheAVL provision of suitable adjusting mecl'ranism.k The shoe supporting forinjis made integral with acurv'ed lever i0' pivoted at 1]. upon the frame of the mach-ine; y The curved'lever under the action of gravity normally swings down tov the position sho-Wn in Fig.l l, but is raised intov an operative po'- sition beneath 'the roll by an operating:arm` 12 lpivotally' connected to the frame of Vfthe'.

end of"k an arin 3,0? which" se is' connected te the arm midway of itsv its ends and serves to im art an oscillatory movement to the arm an roll. The link is actuated by a train of mechanism comprising a drive pulley 33 mounted upon a main drive shaft 34, and a pair of intermeshing gears 35 and 36 mounted upon the drive shaft 34, and counter shaft 37 respectively. A crank 38 is mounted upon the shaft 37 and oscillates a lever 39 through a cross head and slide connection 40. The lever 39 is formed as a bell crank and is pivotally connected to the frame of the machine at 41. The opposite arm of the lever 39 is connected to the lever 32 at 42 so that upon rotating the crank 38, the lever 39 is osoillated to impart the desired movement to the roll l. In order to vary the extent of movement of the roll, mechanism is provided for moving the point of connection 42 toward or from the pivotal point 41 of the bell crank 39. To this end the link 32 is pivotally connected to a curved slide 43 which is retained in curved Ways 44, formed in one face of the lever 39. A rack 45 is cut upon the rear face of the slide 43 and meshes with a pinion 46 journaled in the pivot pin 41. This pinv ion meshes upon its opposite side with a segmental gear 47 formed upon one end of the bell crank lever 48, pivoted to the frame of the machine at 49. The free end of the bell crank 48 is provided with a spring pressed detent 50 arranged to be inserted in any one of a series of recesses 5l formed in the side of the machine. Thus by adjusting the position of the lever 48 the pinion is rotated to correspondingly adjust the slide 43 and vary the travel of the roll 2.
While it is preferred to employ the specic construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed lor modified Without departing from the broader features of the invention.
Having thus described the invention, What is claimed is 1. A sole pressing machine, having in combination, a member for supporting the Copies of this patent may bc obtained for shoe after the last has been removed arranged to project Within the shoe and support the shank portionof the shoe While leaving the forepart of the shoe unsupported, and a pressing member arranged to operate upon the shank portion of the sole and coperate with the supporting member to press the shank portion of the sole and impart the desired transverse curvature thereto.
