Filed Feb. 27, 1958, Ser. No. 717,975

12 Claims. (Cl. 12-20) This invention relates to apparatus for use in the manufacture of shoes and in particular to fastening a sewing rib strip, of the kind disclosed in my pending application for United States Patent Serial No. 665,764, filed June 14, 1957, to the marginal edge of an insole. It is to be understood however that it can be adapted for use to apply other kinds of narrow strip material to insoles and the like without departing from the spirit of the invention.

The principal objects of the invention are to provide an apparatus for applying the rib strip to the marginal edge of an insole rapidly, firmly and with great uniformity, particularly around the ends with a minimum amount of pleating, to provide apparatus in which the several instrumentalities operating to support the insole, efiect movement thereof, apply the rib strip to the marginal edge and cut it off, are correlated in such a way as to simplify control of the operation, and to make it substantially automatic. Other objects are to provide an apparatus with improved mechanical movements which reduce the number of parts necessary for attainment of the operation to a minimum, thereby reducing the possible number of breakdowns and adjustments, making it possible for the operator in most cases to repair and adjust the apparatus himself without having to call the shop mechanic and hence with less loss of operating time. Still other objects are to provide an apparatus which is less expensive to manufacture because of the small number of operating parts and is more efiicient in operation.

As herein illustrated, the apparatus comprises means mounting instrumentalities for movement relative to each other to engage the opposite sides of an insole, one of which is a support for one side and a portion of an edge of the insole, and the other of which is feeding means for engagement with the margin of the insole at the other side, the latter being movable to effect movement of the insole peripherally while in contact with the edge support. There is means for driving the feeding elements and a manually operable lever operably connected to the support, so that movement of the lever from an inoperative to an operative position will bring the support and feeding means into engagement with the insole and simultaneously initiate operation of the driving means. The rib strip is supplied to the insole by a rib strip guide arranged adjacent the feeding means which holds the leading end of a rib strip close to the plane of the insole, in a position to be pressed against the insole by the feeding means when the latter is operated. The support is movable on its mounting, relative to the feeding means, in a plane parallel thereto, while engaged with the insole, to permit shifting the insole transversely, relative to the rib strip guide to vary the position of the application of the rib strip to the margin of the insole. For simplicity of control the aforesaid control lever is also operable while in its operative position to eifect shifting of the support parallel to the feeding means. A cutter is mounted adjacent the near side of the feeding means for cutting off the rib strip when enough has been 2,984,848 Patented May 23, 1961 applied to the insole and there is means for actuating the cutter, operation of which is initiated by movement of the lever toward its inoperative position. Since the rib strip is severed at the near side of the feeding means the leading end must be advanced sufficiently to be engaged between the insole and the feeding means by the guide for the next operation. Accordingly, there is means operable by the actuation of the knife operating means for retracting the guide just before the knife severs the strip and other means for advancing the guide, following retraction, to restore the guide to its initial position so as to project the leading end of the strip between the feeding means and the insole. There is means supporting the feeding members, operable to effect a resultant movement of the feeding members having components of movement perpendicular to the plane of the support and oscillatory parallel to the plane of the support relative to an axis perpendicular thereto. The motion of the feeding members is produced by concentrically arranged cylinders, to which they are attached, the latter being oscillated about their longitudinal axes and reciprocated along their longitudinal axes by a drive shaft through a ball coupling. The feed members have prongs which impale the insole during feeding movement, a presser foot movable therewith which engages the flange of the rib and presses it against the insole and assist in advancing the rib together with the insole during its peripheral movement, and for the purpose of applying the rib herein described, there is a groove between the prong and the presser foot to accommodate the rib.

The invention will now be described in greater detail with reference to the accompanying drawings in which:

Referring to the drawings, the apparatus has a hollow base 10, at the upper end of which is mounted a head casting 12, which supports the operating instrumentalities, which comprise a work support 14, feeding and applying means 16, guiding means :18 and cutting means 20, in cooperative relation.

The head casting has near its base, at the rear side (Figs. 1 and 5), a horizontally disposed shaft opening 22, within which there is rotatably mounted a shaft 24, with its ends projecting from opposite sides of the casting. A sleeve 26 is mounted on the left-hand end of the shaft 24 and secured thereto by a pin 28. An arm 30 is formed integral with the sleeve and extends radially from the axis of the shaft 24. At its distal end the arm 30 contains an opening 32 (Fig. 7), the axis of which is parallel to the axis of the shaft 24 and in this opening there is press-fitted a sleeve 34, which has on it a collar 36 for engagement with the inside of the arm and which provides an abutment for a step 38 mounted on the sleeve. A spindle 40 is mounted in the sleeve and has at its inner end the support 14 which is in the form of a disc, the center of which coincides with the axis of the spindle. At the back side of the disc there is a boss 42 which serves as a bearing for one end of a compression spring 44, disposed between it and the step 38. A pairof lock nuts 46 are threaded on the spindle at the outside of the arm and are adjustable to vary the compression in the spring 44 and hence the yield of the support 14. A key 41 on the spindle, engaged within a slot in the sleeve, prevents rotation thereof.

The sleeve 26 has on it a lug 48 (Fig. which projects downwardly from the underside thereof and there are a pair of screws 50 mounted in bosses 52 on the head casting, below the sleeve, which are adapted to engage opposite sides of the lug and by suitable adjustment fix the angular position of the arm with reference to the axis of the shaft 24 and hence the position of the support 14 with reference to the feeding and pressing instrumentali-ties 16.

At the opposite end of the shaft 24 (Figs. 1 and 6), that is, the right end there is a handle 54, the butt of which is bifurcated at 56 and rotatably fastened to the flattened end 58 of the shaft by means of a pin 60. The bifurcated portion of the handle is shaped to provide eccentric cam surfaces 62, portions of which are located at diiferent radial distances from the center of the pin 60, so that by swinging the handle from one position to another the shaft 24 may be shifted axially in the head casting to move the support 14 toward and away from the feeding and pressing means. The cam 62 bears on a fiat 64 ground on the casting and is held thereagainst by a tension spring 66, one end of which is connected to the pin 60 and the other end of which is connected to the head casting.

The work support 14 (Figs. 1, 2 and 7) has on it a pair of

guides

68 and 70 for supporting the edge of the insole with its surface resting against the inner side of the disc and these are so angularly related, as shown in Fig. 10, as to produce in a conventional and well-known manner continuous peripheral turning of the insole when a feeding force is applied to its opposite side. As shown, the support 68 is concentric with the disc and formed integral therewith. It is to be understood, however, that the

guides

68 and 70 may be adjustably mounted on the support so as to permit varying their positions relative to each other and to the feeding means for different kinds of work. The guides may have fixed surfaces or roller surfaces mounted for turning on axes parallel to the axis of the disc.

The head casting has near its upper part (Figs. 5, 6, 10, 11 and 12), a horizontally disposed opening 72 within which there are mounted concentrically arranged

cylinders

74 and 76. A bracket plate 78 is fastened to the left-hand end of the cylinder 74 (Fig. by screws 80, which overlaps the left end of the cylinder 76, from left to right, as seen in Fig. 10, and carries at its inner edge one of the feeding and pressing members 20. The other feeding and pressing member has a rearwardly extending stem 82 (Fig. 11) which extends into an opening in the cylinder 76 and is held therein spaced from and substantially parallel tothe first feed and pressing member by a bracket 84 (Fig. 10). The bracket contains arslot 86 for reception of a screw 88, by means of which it may be adjusted and a notch 90 for engagement with the upper end of the feeding and pressing means so that the latter may be shifted a little, to either side of its parallel relation to the first feeding and pressing means.

At the right-hand end of the cylinder 74 (Figs. 1, 2 and 6), there is fastened a plate 92 which has at its lower side a collar 94. A plate 96 is fastened to the right-hand side of the cylinder 76 and this has at its lower end a collar 98. Each of the collars has mounted in it a ball bearing assembly 100, consisting of a cage and a race which are of arcuate section, so that the parts are movable angularly with respect to each other, as well as about their common axis of concentricity. A vertical shaft 1592 (Figs. 2 and 6) is mounted in the head casting below the collars and has fastened to it a pair of eccentrics 104 and 106 disposed 180 apart, which are engaged within the races of the two ball bearing assemblies. A pulley 108 (Fig. 2) is mounted on the lower end of the shaft 102 within the base :10 and has entrained about it one end of a belt 110, the opposite end of which is entrained about a pulley 112 fast to the shaft 114 of a motor M bolted to the inside of the base. Rotation of the shaft 102 will effect rotation of the eccentrics in such fashion that the

cylinders

74 and 76 will be rocked about their common horizontal axes and reciprocated axially, this motion being permitted by the ball bearing assemblies described above. As a result of this combined reciprocation and rotational movement the feeding and pressing means 20 have components of movement perpendicular to the plane of the support 14, and oscillatory parallel to the plane of the support relative to an axis perpendicular thereto. The feeding members are moved alternatively so that as one member is moving into engagement with an insole the other is moving out of engagement and as one is moving in a direction to advance the insole while in engagement therewith, the other is moving in the opposite direction out of engagement with the insole to a position from which it may again be moved into engagement with the sole. Thus a step by step feeding motion is had which has an additional function, as will appear hereinafter, to press the rib into place.

Movement of the feeding and pressing means is initiated by swinging the handle 54 from a position in which its longitudinal axis is'perpendioular to the casting, into the position shown in Fig. 1. As the support 14 is moved toward the feeding and pressing means, so as to engage the insole therebetween, a pin 116 (Fig. 2), slidably mounted in the head casting is engaged by the sleeve 26 as it is moved toward the right, so as to press the trip 118 of a microswitch s1 for starting the motor M When the handle 54 is swung to the right the pin 116 will be released and the switch s1 will cut the motor 01f so that the feeding means will be discontinued.

Each of the feeding and pressing means 20, as shown in Fig. 8, is provided with a feed tooth 120, in the form of a prong which bites into the surface of the insole and hence insures positive feeding movement thereto and a presser foot 122 situated above it and to the rear which is roughened somewhat so that it not only presses the rib against the insole, but also helps to feed it. Between the tooth 120 and the pressing foot 122 there'is a triangular notch 124 for slidably receiving and holding the triangularportion r of the rib of the strip s (Fig. 4), as it is being pressed against the insole so that it will not be crushed.

The rib strip s, as seen in Fig. 4, has a triangular portion r and la flange f and is supplied from a reel or other suitable source to a guide 18 (Figs. 1, 7, 9 and 11), which leads it up to a point close to the support 14, so that the leading end of the rib will be caught between the insole and the feeding and presser means each time an operation is commenced without the operator having to introduce it by hand. The guide comprises a flat plate 126 for engagemnet withthe base of the rib and a block 128 having a triangular groove 136, mounted parallel to each other to provide a passage for reception of the fiat and triangular portions of the rib strip. The plate 126 is preferably elastic so that it frictionally holds the strip against the block 128 and will thus advance the strip from its source of supply as long as it is not constrained, but will slide on the strip if the leading end is caught, so as to take up a new position. The guide has at one side an arm 134 which is pivotally mounted on a pin 136 carried by one arm 138 of a bell crank lever. The bell crank lever is pivotally mounted on a vertically disposed spindle 140 (Figs. 1 and 6), and its opposite arm 142 lies opposite the right-hand end of the cylinder 76. A flat spring 144 is fastened to the arm 138 and bears against the arm 134 so that the guide 18 is normally held engaged with a limit pin 146, threaded into the casting, the position of which may be changed to change the angular position of the guide with reference to the support 14 and the feeding and pressing means.

The cylinder 76 has an opening 148 through it from end to end in which there is mounted a spindle 150, one end of which projects from the right-hand end thereof and has on it a fiat head 152 ('Fig. 7), and the other end of which projects from the left-hand end and has on it a cylindrical head 156. A spring 158 mounted on the spindle 150, between its head and the cylinder, normally holds the spindle displaced toward the right with the head 156 retracted. The head 156 carriers a cutter 157 and hence the latter is normally held retracted, that is, rearwardly of the feeding and pressing means. The cutter is employed to sever the rib at the end of the applying operation and is effected by the bell crank lever in such a manner that the guide 18 is retracted and slides along the rib strip while still held gripped between the support and the feeding means so that the latter may take up a new length of tape just before it is cut. To this end the spindle 144) (-Fig. 6) extends downwardly through the head casting into the base and has on it an arm 160, the distal end of which is connected to the plunger 162 of a solenoid 164. A switch s2 is provided for energizing the solenoid 164 and this is tripped by a finger 166 at the lower end of a spindle 168, journaled in the base, with its upper end extending therethrough close to the handle 54. An elastic finger 172 is fastened to the upper end of the spindle 168 in a position to be passed over by a latch 174 fast to the arm '54 when the arm 54 is moved into operative position without turning the spindle 168 and in the opposite direction to turn the spindle 168 and hence to trip the switch s2. A spring 176 holds the spindle in opposition to the passage of the latch 174 so that the finger 166 is pressed against the switch S2, thus hold the contacts of the switch open. When the handle 54 is swung to the inoperative position, that is, toward the right, the latch, by passing engagement with the finger 172, rotates the spindle clockwise which moves the finger 166 at its lower end away from the switch s2, thus permitting the switch to close and momentarily energize the solenoid so as to operate the cutter. The switch is re-opened immediately by the action of the spring 176 which returns the finger 166 to its initial position. Simultaneously, the feed guide is retracted along the tape and then is advanced to advance the leading end of the tape into position for the next operation.

In preparing the apparatus for operation the leading end of a rib strip s is threaded through the guide 18 so that a portion of it projects beyond the inner end of the guide close to the inner side of the support 14. An insole b is then placed with its outer side against the support 14 and with its edge against the edge guides 68 and 70. The arm 54 is then swung from right to left so as to draw the support and the insole resting thereon into engagement with the feeding and pressing means. At the instant the sole is gripped between the support and the feeding and pressing means the latter are actuated to advance the insole step by step, peripherally and simultaneously to press the rib strip into contact with the marginal edge of the sole. By adjusting the screws 50-50 against the opposite sides of the lug 48, spacing of the rib from the marginal edge may be fixed if the latter is to be uniform throughout. If it is desirable to have the rib applied at difierent distances the screws 50-50 may be backed off and the rib shifted in and out as by tilting the handle 54 about the horizontal axis of the shaft 24. When enough tape has been applied for the purpose desired the handle 54 is shifted to the right. During the initial moment of shifting the guide 18 is Withdrawn along the rib, the latter still being held, it is then cut off by forward movement of the knife, whereupon the support is shifted to the left to release the insole so that the latter may be removed with the rib completely applied thereto. It is obvious from the foregoing sequence of operation that the entire operation may be effected and controlled by a single control lever or handle and that the position of the rib may be shifted at will for the best disposition as it is laid around the ends of the insole and along the curved parts at the shank. While the rib, as shown in Fig. 3, does not go all the way around the heel it may extend all the way around.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
