7 Claims. (Cl. 12-24.5)
This invention relates to machines for presenting and attaching binding strips to footwear or parts thereof. It has an important field of use in the manufacture of platform soles or shells and will be described for illustrative purposes in that connection although not limited to that nor to any specific use.
In one aspect the invention comprises a new and improved cutting unit for severing a continuous binding strip in gauged relation to the starting end of the partially attached strip so that the two ends of the strip may be evenly and closely butted. In another aspect it comprises a novel combination of work supporting and feeding means, strip-presenting means and strip-severing mechanism.
in the machine of my co-pending application for Letters Patent Ser. No. 177,187, now Patent 2,654,103, dated October 6, 1953, is disclosed a machine for making platform soles or platform shells by presenting and attaching to the marginal edge of a flat sole blank a continuous binding strip that provides a stifi upstanding Wall enclosing a sole-shaped area into which is subsequently fitted the lasted upper of the shoe. Heretofore the operator has stopped the machine shortly before the attaching circuit is completed and severed the binding strip at a point somewhat removed from the edge of the sole in an endeavor to match the severed end of the strip to the attached starting end. The severing operation has been effected with scissors or a knife and its location has depended wholly on the attention and skill of the operator unassisted by any gauging mechanism. As might be expected, the results have been uneven and considerable waste has been occasioned by severing the binding strip at a point too short to reach the attached starting end.
The object of the present invention is to provide cutting mechanism as an element of the machine that may be operated in gauged relation to the starting end of the binding strip.
To this end an important feature of the invention consists in a freely movable gauge element that may be conveniently moved by the operator from an inoperative initial position out of the path of the work into gauging contact with the previously attached starting end of the strip and which then serves to determine the exact location of the cut. As herein shown this gauging. function is carried out by one blade of the cutting mechanism, thus contributing to the compactness and convenience of my novel construction.
A further feature of the invention, accordingly, consists in a pair of cutting blades of which one has a gauging face in addition to its sharp shearing edge and which is arranged to remain at rest in its gauging. position while the other blade of the pair is operated to sever the binding strip.
As herein shown, a tilting and rocking support is provided for the cutting blades such that they may be freely moved to establish they required gauging relation with the attached starting end of the binding strip throughout an appreciable range of positions in which the end may be found in the particular work in hand.
in another aspect the present invention includes novel mechanism for presenting and applying a binding strip at right angles to the peripheral edge of a flat sole blank. This comprises a roll mounted for free rotation and cooperating beveled roll so located as to support the solo from beneath and at the same time positively grip and position the binding strip, the outer rim of the beveled roll tucking the inner flanged portion of the strip into the vertex of a right angle with the body of the strip.
These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which:
Fig. 1 is a view of the machine in front elevation,
Fig. 2 is a corresponding plan view,
Fig. 3 is a fragmentary view of the machine as Seen from the left in Figs. 1 and 2, and
Fig. 4 is a fragmentary view showing the cutting blades operatively gauged in severing position.
The present invention is herein illustrated as applied to a machine of the general type disclosed in United States Letters Patent No. 2,654,103 above identified, although it is not limited in its application to this or to any specific machine.
The frame of the machine includes a column, not shown, supporting an overhanging head 10 in which is journaled a driven shaft 9 having a pair of eccentrics which operate feeding feet 12 causing them to move alternatively in generally elliptical paths with a flat feeding component. The mechanism by which the desired movement of the feed feet is brought about is not hereindisclosed since it forms the subject-matter of my prior Patent No. 1,794,204, February 24, 1931, to which reference may be had for a full and clear description of the feeding mechanism of the present machine.
The frame includes a lower outwardly projecting portion 11 which carries all the other operative instrumentalities of the machine through the medium of an auxiliary casting or auxiliary frame 13 pivoted about a shaft as to the main frame part 11. The auxiliary frame 13 is formed at its outer end as a vertical undercut downwardly extending guideway 14 and-upon this is adjnstably mounted a carriage 15 controlled in its" vertical position by an adjusting screw 16 which. is threaded into the lower end of the guideway 14; Projecting outwardly from the upper end of the carriage 15 is a boss 17 in which is journaled a short shaft, not shown, carrying a flat roll 13 which is thus rotatably mounted for free movement about a horizontal axis. The roll 1% acts at the upper portion of its rim to support and position the binding strip by engaging its bottom edge as it is brought to the point of application.
The carriage 15 has an outwardly projecting arm- 19 to which is adjustably secured a plate 20 that extends transversely toward the right as seen in Fig. 3- and across the outer face of the roll 18. The plate 20 isadiu-stab-ly secured to the arm 19 by a bolt 2t which it is slotted to receive. At the outer end of the plate 20 is secured a vertical. bracket 22 and' upon the upper end of this is mounted for free rotation a beveled corrugated worksupporting roll 23; The bracket 22 lies close to but does not touch the outer faceof the roll 18. The roll 23 is rotatable about an axis inclined approximately 45 to the horizontal so that the upper portion of its surface is substantially horizontal and lies at a level above the top of the rim of the fiat roll 18. The roll 23 is provided with a slightly projecting rim which serves to tuck the flange of the binding strip into the vertex of'a right angle with 'vided bearings for a horizontal shaft 30.
the shaft carries a projecting arm 31 and to the outer the upstanding portion of the binding strip in cooperation with an edge gauge roll 24 mounted to rotate about a vertical axis on a journal projecting upwardly from the auxiliary frame 13.
The auxiliary frame 13 is provided with a pair of spaced upstanding bosses 28 and 29 in which are pro- At its rear end end of this is attached a vertically disposed tension spring 32 secured at its lower end to an angle bracket 32. The
'arm 31 carries an adjustable stop screw 33 which bears upon the surface of the frame 13 and so adjustably determines the initial angular position of the shaft 30. As seen in Fig. 1, the shaft 33 is free to rock about a horizontal axis in .a clockwise direction lifting the arm 31 against the tension of the spring 32, the shaft when released and the parts carried by it being automatically returned to the initial position determined by the setting of the stop screw 33.
Fast upon the other end of the shaft 31 is a sleeve 34 having a radiallyextending boss 35. Upon this boss is pivotally mounted a vertical plate 36 merging at one end into a handle 37 and at the other carrying the lower cutting blade 38." The boss 35 provides bearings for the plate 36 that permit the plate to rock about an axis disposed at a substantial angle to the axis of the shaft 30. As
, shown in Fig. 1, this axis extends rearwardly and downwardly at an angle of about 45 but it will be seen that the axis will approach a vertical position asrthe shaft 30 is rocked in lifting the lower cutting blade 38. The plate 36also carries an outwardly projecting journal stud 39 upon which is pivotally mounted a plate 40 having a circularboss 41' provided with slots for stop screws 42 which are threaded into the plate 36 and limit the relative angular movement of the blade carrying parts. The plate 40 merges outwardly into a handle 43 between which and the handle 37 is interposed a coil spring 44 tending always to separate the two handles to some such position as that shown in Fig. l as determined by the stop screws 42. The plate carries at its forward end the upper blade 45 and in initial position of the parts the blades 38 and 45 are open and maintained by the spring 32 in'position below and at one side of the work support provided by the rolls 18 and 23. The plate 36 with its associated blank is presented upon the rolls 18 and 23 with the end of the binding strip 51 caught between the inner edge'of the insole '50 and the edge gauge roll 24 and with the upstanding portion of the binding strip caught between the outer face of the roll 24 and the rim of the beveled roll 23; When the machine is set in operation the feed feet 12 advance the sole away from the operator the level of the top of the rim of the flat roll, and an edge f previously attached end of the binding strip. As soon as the strip has been severed, the handles 37 and 43 are released and the shearing blades are returned to their lowered inoperative position. The machine may then be restarted and the sole run through to complete the attachment of the binding strip.
The gauge roll 24 is provided with an upwardly flaring circular deflector 25 mounted concentrically with the roll and shaped to turn over the upstanding marginal portion of the binding strip cover, bringing it into range of the feed foot 12. i
It will be seen that the flat side face of the lower blade 38 acts as a gauging element and that its shearing edge cooperates with the upper blade 45 in severing the bind- 7 stop bolt are not'shown herein but may be like the corresponding elements described in the machine of my copending application above identified.
