EYELETING MACHINE.
Application iled April 14, 1923.
To all whom it may concern:
Be it known that I, LORENZ MUTHER, a citizen of the United State-s, residing at Newton Center, in the county of Middlesex 'and State of Massachusetts, have invented a new and useful Improvement in Eyeleting Machines, of which the following is a specification, reference beinghad therein to the accompanying drawings.
This invention relates to eyleting mz.- chines and more particularly to such machines adapted for setting blind or invisible eyelets; that is, eyelets which are set in one or more layers of a plurality of layers and clenched upon an inner or intermediate layer.
Heretofore, in the manufacture of shoes in which invisible eyeleting has been eX- tensively used, it has been customary to employ machines having a clenching tool provided with a setting shoulder so restricted in diameter as to be capable of passing through the lacing hole in the outer layer of the shoe in order to clench the eyelet upon an inner layer. ing the operation ofthe machine, the movement of the outer layer over the setting shoulder and out of the way of that portion. of the eyclet which is turned over and clenched upon the inner layer, that portion of the setting tool above the setting shoulder should be so formed as to offer as little resistance as' possible to the passage of the setting shoulder.
The object of my invention is the provision in an eyeleting machine of an eyelet setting device having a restricted setting shoulder adapted to pass through the hole in the outer layer or layers of a plurality of layers and being so formed above said setting shoulder as to facilitate the movement of the outer layer or layers upwardly 'above the setting shoulder and out of the way of the eyelet while it is being clenched by said setting shoulder upon an inner or intermediate layer.
Other objects of the invention will be more specifically set forth and described hereinafter. y
One of the features of my invention resides in providing that portion of the setting device above the setting shoulder with a plurality of small flat surfaces whereby that portion of the tool, although substantially circular in cross-section, is actually polygonal. By means of this construction,
In order to facilitate, dur-` Serial No. 632,110.
the friction between that portion of the tool and the circular edge of the outer layer at,
the hole is reduced and the passage of the outer layer upwardly over the setting shoulder is thereby facilitated.
The invention is illustrated as applied to a setting or clenching tool adapted for use in that tyye of eyeleting machines shown in United tates Letters Patent No. 686,928, granted to Glass, Nov. 19, 1901. In that. type of machine the upper setting or clenching tool has its end formed for punching a lacing hole. My invention, however, is not to be limited to any particular eyeleting machine since it is capable of general use and may be embodied in a tool for setting the eyelet alone or in a combined punching and setting tool.
ln the drawings illustrating my invention, Figure l is a side elevation of a setting tool constructed in accordance with my invention and adapted foruse in the said Glass machine; Fig. 2 is an end elevation looking upwardly in Figure 1 toward the punching end of the tool; Fig. 3 is a vertical cross sectional view on line 3 3 in Figure 2; Fig. i is a similar view on line 4 4 in Figure 2; and Figs. 5 to 9 inclusive are diagrammatic views of dierent stages in the setting of a blind eyelet bythe use in the Glass machine of a setting device embodying my invention.
ln the drawings there, is shown a setting device having a setting shoulder lO, sufficiently restricted in diameter to pass through a hole in the outer layer of a plurality of layers and of such shape as to turn over the end of the eyelet and clench it upon the inner or intermediate layer. To facilitate the passage of the. setting shoulder through the hole in the outer part or parts, the portion 12 above the setting shoulder is slightly reduced in circumference by having a plurality of flat surfaces 14 cut thereon, thereby changing its cross-section from a circle to a polygon. As a result of this construction, the friction between the portion l2 and the edge of the hole is sufficiently `reduced so that the outerlayer or layers are easily pushed above the setting shoulder in the operation of the machine and out of the way of the end of the barrel of the eyelet which is turned over by the clenching shoulder 10 upon an intermediate layer.
In making these cuts, care must be exercised to prevent cutting away too much of the clenching shoulder, otherwise some of the prongs of the split barrel of the eyelet may not be turned over. I have found that good results may be secured by cutting from eight to ten such surfaces on the tool so that a cross-section of the portion l2 is either octagonal or polygonal with nine or ten equal sides. It will be observed that the lines of juncture lb between the curved setting shoulder l0 and the various flat surfaces la are curved downwardly which indicates a slight cutting away of 'the setting shoulder and therefore the number of flat surfaces must not be reduced to such an extent as to impair the function of the setting shoulder.
The end of the setting device may be provided with a cutting edge 18 for punching Out a round hole for the lacing, in which case the device is bored its entire length, the bore 2O permitting the punched centres to pass upwardly and ont at the top. Above the portion l2 the setting tool may have a permanent shoulder 22 and above that it may be provided with a threaded shank 2% whereby the device may be adjustably mounted in the punch-bar of the eyeleting machine.
In Figures 5 to 9 inclusive of the drawings7 I have shown diagrannnatically five different stages in the setting of a blind eyelet by the use in a Glass machine of a combined punch and set embodying my invention. Such use is merely for purposes of illustration since my invention is not limited to any particular type of machine nor to a combined punch and set. In these iigures, is shown a portion of the work-support 30 having an opening 32, a combined punch and set embodying my invention above the work-support, and a lower set 34 having a central spindle 36 for positioning the eyelet.
In Fig. 5 the parts are shown in normal starting positions. A shoe upper comprising a leather or outer portion 4:0, a lining l2 and a facing Hl-llis laid, with the leather portion uppermost, upon the work-support 30 underneath the punch. An eyelet i6 is shown mounted on the lower set and held therein by the spindle.
In F ig. 6 the partsare shown at the end of the punching operation. Upon the starting of the machine the punch descends and punches a hole through all the thicknesses of the upper andthe lower set carrying the eyelet starts to move upwardly.
In Fig. 7 the parts are shown at the end of the feeding movement. After punching a hole through the upper, the punch is raised suficiently to release it from the worl; support 3() and is then moved from right to left carrying the upper with it to a point directly over the lower set 34. Meanwhile the lower set has been moving upwardly in a vertical direction toward the punch.
After the punch reaches the end of its feeding movement, the lower set continues to rise, the spindle 36 being retracted within the lower set, until finally the eyelet pushed up around the end of the upper set and against the setting shoulder lO which splits the eyelet on previously scored lines and turns the split points over. During the foregoing operations the outer or leather portion is pushed over the setting shoulder l0 and out of the way of the eyelet as shown in Fig. 8. In this view the eyelet is shown midway in the clenching operation from which point it is finally pressed down upon the lining as shown in Fig. 9 which shows the condition of the upper after the setting tools have returned to their initial position, the eyelet AIG being set in register with the hole 48 in the outer or leather part.
lVhat I claim is l. In an eyeleting machine, a setting tool having a restricted setting shoulder adapted to pass through a hole in the outer layer of a plurality of layers and set an eyelet upon an inner layer and having that portion above the setting' shoulder polygonal in cross section and provided with sides suliicient in number to avoid impairing the function of the setting shoulder and few enough in number to substantially reduce the friction between the outer layer and the tool when the said outer layer is passed above the setting shoulder during the operation of the machine.
2. In an eyeleting machine, a combined punching and setting tool having a restricted setting shoulder adapted to pass through a hole in the outer layer of a plurality of layers and set an eyelet upon an inner layer and having that portion above the setting shoulder polygonal in cross section and provided with sides sufficient in number to avoid impairing the function of the setting shoulder and few enough in number to substantially reduce the friction between the outer layer and the tool when the said outer layer is passed above the setting shoulder during the operation of the machine.
In witness wliereof, I hereunto set my hand this twenty-rst day of March, 1923.
LORENZ MUTHER.
