LACING-S'IUD-SETTING MIAGHINE Application filed November 22, 1923. Serial No. 676,238.

This invention relates to fastener-inserting machines and more especially to those in which pieces of reinforcing material are automatically applied to the work to strengthen the anchorage of the fasteners. For example, United States Letters Patent No. 1,129,030, granted February 16, 1915, on application of E. E. l/Vakefield, illustrates a machine for setting lacing-hooks in shoe uppers and having automatic means for feeding a strip of reinforcing material and means for cutting the strip into sections so that each section will reinforce the anchorage of a hook in the upper. The present invention is illustrated as embodied in a machine of the type shown in said patent, but is not limited to a machine of that type or to inserting lacing-hooks, and it is to be understood that the expression fasteller-inserting used through this specification is intended to have a broad meaning.

According to the construction shown in the aforesaid patent, the strip of reinforcing material is fed with the same amplitude of movement as the work, and the individual pieces of reinforcing material into which the strip is cut are necessarily of the same length as the feeding steps imparted to the work. In some cases the feeding steps of the work are only one-half inch long, but when a strip of reinforcing material is cut into sections one-half an inch in length there is not sufficient margin at one side of the fastener (specifically, the left side) to insure secure anchorage of the fastener.

In view of the conditions explained above, an object of the present invent-ion is to provide improved means for feeding a reinforc ing strip a suitable distance to fulfill its purpose in the highest degree irrespective of the spacing of the fasteners one from another, so that when, for example, the feeding steps of the work are relatively short the reinforcing strip may be fed to a greater extent and cut into sections longer than the feeding steps of the work.

With the above obj ectin view, a feature of the invention consists in an organization comprising fastener-inserting mechanism, means for feeding the work step by'step, means arranged to feed the strip a greater distance than the work is fed, and means arranged to cut the strip into sections longer than the feeding steps of the work. In practice, this results in a series of'individual sections the leading edges and trailing edges of which are lapped one over another.

l/Vhen the invention is embodied in a machine of the type illustrated in the aforesaid patent a novel feature consists in s'u plee mental means for feeding the reinforcing strip beyond the point to which it is fed with the work.

Other features of the invention are hereinafter described and claimed. and are illus trated by the accompanying drawings.

in the accompanying drawings Figure 1 IS a front elevation of a lacing hook setting machine to which my improved showing the parts advanced to that stage of the cycle at which a section ofthe reinforcing strip is severed and the materials are punched.- Figure 4 shows a later stage of the cycle, the work and the reinforcing strip having been fed the same distance to theleft, the severed section and a fastener having been applied to the work, and the reinforcing strip being'about to receive a supplemental feeding movement. I

Figure 5 is a perspective view showin how the supplemental strip-feeding means may be mounted on the presser-foot. v Figure 6 is a section on line 66 of F igure 5. 7

Figure 7 is a section showing two specimens of work provided with a lacing-hook and an eyelet respectively and each provided with a section of a reinforcing strip.

Figure 8 is a view of the upper face of a" piece of. work provided with sections of a reinforcing strip cutand applied according to this invention.

The illustrated fastener insertingmachine is similar in construction and operation to that shown in the patent above referred to. It comprises a reciprocating head 10 arranged to slide horizontally on theguide bars 11 for the purpose of feeding the work 17. This head carries a guide block 12 arranged to slide in the grooves 13 of the presser foot 14. This guide block 12 is provided with a slot 15 through which a reinforcing strip of tape 16 extends and is. also provided with apertures 22 through which the tape-engaging.

needles or spurs 21 pass when forced into the tape prior to feeding the same.

These needles or spurs are fastened to a bar 23 which is carried by a spindle 18 to move therewith. A knife 20 is also fastened to the member 23 and extends downwardly to engage the left hand face of the block 12 so that when the spindle descends the knife enp a and severe a portion 2 1 of the tape which extends beyond the block. The downward movement of this spindle 18 also causes the punch 19 to punch ahole through the reinforcing strip and through the work 17 lying on the punch-block 45 (see Fig. 3). The presser-foot 14: now rises to release the work so that it may be fed. The head 10 is now moved to the left, whereby the punch feeds the work and the severed section of the strip while the spurs 21 feed the body of the st "ip to the same extent. The presser-foot is now lowered, the carrier 26 is raised to insert the fastener 25, and the fastener is clenched by the anvil portion 27 of the punch. The punch now rises to the position shown in Fig. 4, thereby disengaging the spurs 21 from the reinforcing strip and raising the knife 20,

following which the'h-ead 10 returns to its initial position shown in Fig. 2.

Now, when the feeding movement of the punch 19 and of the spurs 21 is short, say one half inch, the leading edge of the strip 16 is advanced only slightly beyond the line in which the punch subsequently descends to punch the next hole,and if the strip remained at the position to which it is fed by the spurs 21 the leading or left-hand edge of the strip would be too close to the hole to provide satisfactory anchorage for the fastener. This difficulty does not arise at the right-hand side of the punch because the severing means is arranged at a sufficient distance from the punch, and so, whatever reinforcing material is sacrificed by shortening the feeding steps of the 'work is necessarily taken from the lefthand side of the punch.

To obviate the difficulty just explained I have provided auxiliary means for feeding the reinforcing strip beyond the point to which the spurs 21 feed it, thus insuring a sufficient margin of reinforcing material at the left-ban d side of each fastener as well at the right-hand side. The construction ofthe illustrated means for this purpose is as follows A. bracket, 28 is fixed to the presser foot support 29 and to this bracket is pivoted at 30 a plate 31 having an outwardly-turned end 32 to which end is secured a downwardly-projecting arm 33 having guide eye 34; in its upper end for the tape 16, and its lower end provided. with a tension device comprising a leaf spring 35 and a plate 36. arranged to clamp the reinforcing strip 16. The arm 33 is braced by a strut 37 which leadsupwardl an d then horizontally as at 38 to engage the forward end of the pivoted plate 31. The clamping couple 35, 36 is normally drawn to the left by a spring 39 and arrested by a stop 40 formed on the plate 31 and arranged to engage the under edge of the fixed arm 28.

A member 42 having a vertical slot 4a is fastened by a screw 43 to the head 10 and has a cam portion l1 arranged to act on the upper portion 38 of the strut 37 to retract the clamping couple 35, 36, while the spurs 21 are feeding the reinforcing strip.

In the operation of the machiiie, when the spindle 13 with its spurs, knife and punch are in down position, as illustrated in Figure 3, the head 10 is moved to the left into the position illustrated in Figure 4, to feed the shoe upper together with the reinforcing strip into position to receive the stud 25, and during this feeding stroke the cam 4t1 engages the member 38 on the pivot plate 31 and tips this plate with its feeding arm back into the position illustrated by solid lines in Figure 41-, causing the clamping couple 35, 36 to slip back along the tape which is at this time held by the spurs 21, as shown in Figure 3. The spurs, knife and punch are now raised to the position illustrated in Figure 1, and as the head with its guide block and mechanism now move to the right the auxiliary feeding arm 33 is released by the cam and returned by the spring 39 to its normal position (brokenlines in Fig. f) to be arrested by the stop 40, and while swinging to this position it imparts a supplemental feeding movement to the reinforcing strip 16. Therefore, when the guide block 12 has reached its initial position 2) a length of the reinforcing strip greater than the stroke of the guide block, is projecting,

beyond the block and is ready to be severed by the, next downward movement of the knife 20. The extent ofthis additional feed of the reinforcing strip may be varied by adjusting,

the operating member 42 vertically.
