EDWARD E. WAKEFIELD, OF PROVIDENCE, RHODE ISLAND, VASSIGNOR 'I'O HALKYARD MANUFACTURING COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.

LAcING-srUD-snrriivc MACHINE.

Patented July 31, 1917.

Application filed February 13, 1915. Serial No. 8,113.

Be it known that I, EDwAnD E. VAKE- rinLD, a citizen of the United States, and i'esident of the city of Providence, in the county of Providence and State of Ilhode Island7 have invented certain new and useful Iinpi'oveinents in Lacing-Stud-Setting Machines, of wliich the following is a specification.

This invention relates to improvements in machines for automatically setting lacing studs sucli as hooks or eyelets in slioe uppers, and has for its object to provide means adapted to work in conjunction with such a machine for feeding a strip of 'reinforcing tape to the shoe upper to be connected to the upper by the setting of the lacing studs thereinto, this tape to serve as a support, reinforcement or backing for the thin upper and to prevent the studs froin pulling out. This invention is an improvement on my co-pending patent application Serial No. 845,989.

A further object of this invention is to provide means whereby the strip may be readily severed after the required length has been connected to the upper.

A further object of this invention is the provision of means whereby the strip may be partially severed if desired as it is being laid on and connected to the upper, to cause the strip to conforin more readily to the curve of the upper without wrinkling or buckling.

It is found in practice in the attaching of lacing studs such as hooks or eyelets to the slioe upper that in the better qualities of goods, it is desirable to sever the hacking strip into a length for each individual stud which will cause this backing to lie flat upon the surface of the upper while being laid in a curve to follow the natural form of the edge of the upper without wrinkling or buckling7 the mechanism for accomplishing which, is set fortli in my prior patent application above referred to, but in the lower grade of goods where the stock is thin and lacking in strength7 I preferably apply this backing strip to the upper in a single length without severing the same between the studs. In this way the maximum reinforcing efi'ect is obtained from the backing strip to strengthen the stock not only about the studs butbetween the same when set.

Then again in applying this backing strip to the medium grade of uppers, it is sometimes found advisable to cut or notch the edge of the strip to allow or perniit it to better conform to the cui've of the upper as it is attached thereto, to avoid in a measure its wrinkling or buckling when laid in a curved form.

Vith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1- is a front elevation of the feeding head pai'tly in section showing the presser foot in engageinent' with the work and the reinforcing tape as being connected to the work by a plurality of lacing studs, and a severing blade being raised so as not to cut the strip when the punch descends.

Fig. 2- is a view of the mechanism illustrated in Fig. 1 showing the punch raised after having set the last stud in the upper and the presser foot in extreme raised position causing the knife to sever the strip.

Fig. 3- is a side elevation showing a portion of the feeding head and'the mechanism through which the presser foot is raised to cause the tape to be brought into contact with the edge of the knife and severed.

Fig. is a plan view of the presser foot showing the guide block through which the tape is fed, as slidably mounted in said foot.

lFig. 5- is a f'ace view of the knife blade showing the edge set on an angle to the plane of the strip whereby it may be adjusted to partially sever the strip between the studs when desired.

Fig. 6- is a view of the inner side of the shoe upper showing the reinforcing tape in one continuous piece all connected to the upper by the setting of the studs.

Fig. 7- shows the reinforcing tape as connected to the shoe upper and this tape as having been partially severed between the studs.

In the z accompanying drawings I have illustrated a hook setting machine with my tape feeding and severing mechanism operatively connected vthereto, but the saine is as well adapted for use on an eyelet setting machine, as the strip serves as a reinforcement for either a hook or eyelet, and I have, therefore, adopted the term lacing stud, which is used throughout the specification and claims and is intended to inclucle both the hook and the eyelet.

I In the accompanying drawings and specification, I have shown and described only sufiicient mechanism to illustrate my present invention.

In the drawings 10 designates a portion of the carriage in which is mounted the punch spindle 11 and the presser foot spindle 12, the latter spindle being supported from the former by the collar or guide blocks 13 and 14:. To this spindle 11 is connected the punch 15 which forms holes in the upper b and also in the strip of stiffened reinforcing tape 16 for the reception of the lacing studs 17, the cutter blade 18 is also shown as being mounted in the blocks 13 and 14 to move with the punch spindle. This cutter is provided on one of its faces with rack teeth 19 which are eng-aged by the pinion 20, the latter being provided with an Operating handle 21, the rotation of which causes the plate 18 to be raised and lowered relative to the spindle carrying the same. A clamping member 22 is provided to engage the head 21 of the pinion 20 to bind and retain the same in any desired position after the knife has been set. By this arrangement, it will be seen that the knife blade may be adjusted vertically, whereby it may be set so as to sever the tape at each setting operation of the stud or itmay be raised so as not to sever the tape eXcept when the presser foot raises the tape up into contact with said blade or again the knife blade may have its edge formed on an angle to the plane of the strip and by this adjusting mechanism the knife may be set to sever just the desired portion of one edge of the strip as the punch descends to set the stud. By this means the same machine may be 'adjusted to perform several classes of work. The guide block 23 is connected to the presser foot spindle 22 and is provided with a longitudinal aperture 24 through it which serves as a guide through which the strip 16 passes, and by which the strip is accurately guided over or to the upper which it is to be laid on and connected in the desired position tliereto.

The outer edge of this block is provided with a hardened plate 25 having an aperture through which the tape also passes and this plate serves to coperate with the edge 26 of the cutter 18, whereby the latter is caused to slide upon that of the former and when it is desired to have the twocoperate the guide block 23 with its plate 25 is raised sufciently toward the edge of the blade to sever the strip passing therethrough.

This block 23 is mounted to slide longitu- (linally in the presser foot proper 27, see Fig. 1, which presser foot is connected through the arm 28, member 29 and spring pressed spindle 30 to be operated from the foot treadle 31 through the connection 32 and lever 33 pivoted at 34:, whereby when it is desired to raise the presser foot to set the work, this treadle is pressed down slightly to permit the work to be entered, adjusted or reinoved therefrom; but when it is desired to sever the strip the presser foot is raised still further causing the two cutter members 25 and 26 to coperate and sever the strip which raising action is obtained by a little further pressure of the foot upon the treadle. By this construction, it will be seen that the strip may be severed at any place desired by a simple operation of the foot treadle which raises the combination cutter and guide block up sufiicient to coperate with the cutter plate.

In the operation of my improved device the tape 16 is led from a reel, not shown, through a suitable guide 35 supported from the arm 3G which is connected to the presser foot 27, see Fig. 4-. In this guide, 1 have mounted a tension spring 37 which permits the tape to advance but prevents the same from reccding or moving backward during the return stroke of the feeding mechanism. From this guide the tape is led through the aperture 21 in the guide block 23 above the engaging surface of the presser foot and over the Cutting edge of the cutter plate 25.

ln setting the machine for the operation of applying a hacking strip to the upper b, the end of the strip is advanced by hand beyond the cutting edge of the block 23 beneath the punch 15. Thepunch now desrends into the position illustrated in Fig. 1 piercing the strip and the upper and then with a lateral motion moves both the strip and upper into the next position over the pocket plate 38 which latter coperates with the punch to set and rivet the studs in the upper and at the same time secures the reinforcing strip to the back thereof. The punch spindle is now raised and inoved to the right a dietance equal to that between the studs, while the upper is held in fixed position by the presser foot. rThe operation above described is repeated at the setting of each stud, the movement of the head to the left serving to draw out the strip and the setting' of the studs secures the strip and the upper together. lllhen the desired number of studs have been set into the upper and strip the head is stopped in the advanced position. illnstrated in Fig. 2 and the operator presses his foot upon the treadle 31 and raises the presser foot and guide block 27 until the knife edge 26 engages and sevei's the strip. The upper is now removed from the machine and another positioned herein and the presser foot lowered to rctain the same.

The next movement of this head in be` ginning its operation upon the fresh upper is to the right, which causes the strip to o extend the desired distance beyond the punch, the next operation forces the punch down through the projecting end of the strip and t-he operation of setting the studs in this upper is repeated in the manner above described.

By the laying of a full or unsevered strip onto the back of the upper, it Will be seen that the maximum support is obtained, that is, the strip not only serves as a support about the stud but also serves as a support between the different studs to stiffen and strengthen the upper materially along` its edge at the point Where greatest strain is exerted.

In some instances, I have provided a knife blade 39 having a cutting' edge 40 set at an angle to the face of the strip as illustrated in Fig. 5 and When this blade is loivered by means of the rack and pinion 19 and 20 its point 41 will pass through the edge of the strip 16 and partly sever the same by which arrangement I secure the effect illustrated in Fig. 7, which as Will be seen pcrinits the strip to more readily conform to the curved edge of the upper Without wrinkling or buckling.

I have shown and described one form of inechanism for attaching the strip to the upper by setting a plurality of studs therein but any means for performing this function Will fall Within the spirit and scope of this invention.
