Specification of Letters latent.

Patented June 22, 1915.

Application filed May 4, 1912. Serial No. 695,064.

T 0 al trim/n it may concern Be it known that I, ALFRED B. \VALES, a citizen of the United States, residing at \l'hitinan. (oimty of Plymouth, State of Massichusetrs, have invented a certain new and useful Improvement in Eyeletiug-Machines. of which the following; is a specification, reference being bad t erein to the accompanying drawings.

, My invention has for its object a machine for setting what are termed blind eyelets.

The invention is fully set forth in the following description, taken in connection with the accompanying drawings and the novel features are pointed out. in the claims at the close of the specification.

What is termed a blind eyelet is an eyelet which is set in the under one of two pieces of sheetmaterial, the upper piece of material serving to cover and conceal the eyelet, and there being in the upper piece a hole which registers with the hole through the eyelet and thus permits the passage of a shoe lace or the like. Such blind eyelets are used to a considerable extent in the uppers of boots and shoes, being set in the lining or facing stay beneath the leather or outer portion of the quarter.

. Hitherto so far as known to me in the setting of blind eyelets both the pieces of leather are first punched. After the punching operation is completed the upper or covermg piece of leather is turned back, and the eyelets are then set in the lining or stay. This entails a second handling of the stock and is a relatively slow operation. With a view to obviating this second handling of the work and improving both the rapidity and economy of the blind eyeleting operation, an object of the present invention is to provide means for alternately performing the step of punching both parts of an uppeer and the step of setting an eyelet inone part of the upper in the hole thus formed in that part, while the two parts are mainmined in the normal relation which is to be preserved in the finished shoe.

To this end. an important feature of the invention is the combination of a feeding member arranged to carry a punched upper into line with an eyelet carrying set, with means acting before the feeding member is withdrawn fromthe upper and upon the barrel of an eyelet inserted by the set through one portion of the upper for clenching the end of the barrel upon the concealed surface of said portion.

By the employment of a machine constructed in accordance with my invention the two pieces of leather are punched and the eyelets are set in the under piece as rapidly and continuously as heretofore a single strip of leather has been punched and eyelets set therein.

One important feature of the invention consists in the provision of a thin work separatin member atlapated to be inserted between te partially attached parts of a shoe upper and serving to separate that part which is to be punched only from that part which is to be punched and eyeleted. An important advantage of such a separating member is that the two parts of the upper may be fed across its opposite faces and any desired or difi'erent operations may be performed independently without difliculty upon the parts of the work so separated.

In the machine herein shown an upsetting die is mounted upon one side of the work separating member and asetting die is arranged to coiiperabe therewith for inserting and clenching successive eyelets in the part of the upper which is fed across the upset ting die. The work separating member upon its other side is made smooth so thatthe other side of the upper, which is to be punched only. can be fed across it without obstruction.

Another important feature ot'- the invention consists in the provision of means for supporting the thin work separating member against the pressure of the setting'aie during the setting operation while at the some time leaving an unobstructed space for the passage of the work on both sides of the separating member between the setting operations. As herein shown this is efiected by arranging the punch to be moved oppositely to the setting die and to engage the smooth side of the work engaging member when the setting die is moved toward the upsetting die.

Still another feature of the invention con sists in so shaping the separating member that it need be inserted only :1 short distance within the edge of the upper. Under such circumstances the se crating member will not interfere with t e inner line of top stitching found in shoes of many styles, .whereas otherwise, it would he neceary to set the blind eyelets before the quarter had been stitched. This would render likely inaccuracies in alinement between the holes and the eyelets when the upper and lining were finally stitched together. One form of separatingmmember which posse$es the ad vantage :1 ve disclosed isjierein shown end comprises a. plate ha'ving a shank portion disposed transversely to the edge of the work and a body portion extending substantially arallel thereto.

As erein shown the work separating member is utilized to strip one piece of ma terial from the feeding member as the work is fed between the punching and setting operations. This constitutes still another feature of the invention and renders it possible to utilize the punch for feeding the work.

In the drawings, Figure 1 is a. plan view of the attachment embodying my invention shown secured to the table of an eyeleting machine, Fig. 2 is a front View of a portion of an eyeleting machine showing my attaclnnent applied to the table thereof, and also showing the lower set and the punch, the latter being in its highest tposition. 3 isasimilarview show ing e it has cut a hole in the two strips of leather. Fig. 4 is a similar view showing the parts in the- 'tion which thefy occupiv completion of the setting 0 the ye at. Fig. 5 is a perspective of a piece of work showing the upper and under stri which nre used in blind eyeletin the un er strip having eyelets therein, an the upper strip holes which register with the barrels of the eye lets.

not limited in its application to this or any particular type of eyeleting machine.

Referring to the drawings, 2 is a part or plate formed preferably from 9. relatively thin flexible sheet of metal. This plate is shaped adapted to be secured by means of screws 3 or equivalent securing devices to the top of the work plate 4 of an eyeleting machine. The plate 2 compriss a body portion, and a shank portion slotted for purposes of adjustment and maintained in place by the screws 3. This shank ortion is mounted upon a small plate or b ock 5 which serves to hold the part '2 above the table 4 so that the lining 6 in-which the eyelets are to be set, may pox under the part '2 while the outer part of the quarter 7 may pass over the said pzirt '2. Running from front to Fig. punch after I at they as shown in plan in Fig. 1, and is -f movement of the punch, and extends in the direction of the feed to and through the neck portion 10 of the part As will be clear to those skilled in the art the stock is fed forward by the punch, after each cutting movement of the latter, a. distance equal to ,the distance between the eyelets.

The part 2 is provided with a projectiug portion 9, the neck 10 of said portion 9 being bent downwardly as shown in Fig. 2 so that the punch 11 when moving forward to feed the stock will pass out of the open ingSand over the forward projection 9. (ii the under side of the projection 9 is secur an upsetting die or upper set member 12 which coti tes with the set 13 of the machine, am when the punch has completed its forward feed movement it is directly over the upper set 1:2 as shown in Fig. 4. The forward feed movement of the punch causes the neck portion of the part 2 to disengage the under portion 6 of the upper from the point of the punch, and the engagement of the punch with the superposed portion '5 of the upper carries the leather forward until the upper setting die is located in the hole just formed by the punch in the lining. hen the punch is in this position the under set 11; with the eyelet 14 in position as shown Figs. 1, 2 and 3 is moved upwardly and the eyelet is inmrted and setin the lower portion 6 as shown Fig. 4, the end of the eyelet bar el being clenched upon the inner or concealed surface of the lower portion. The part together with its projecting end J may he made of comparatiaolv thin sheet material, because at the time the eyelet is set it is backed up by the punch and is therefore held rigidlyzmd prevented from yielding.

After the eyelet is set the punch mow-s upwardly and tounrd the right as seen in the figures and again descends through the slot 8 cutting holes in both the upper anti lower pieces 7311:! tand again feeds the stock forward topping dhectly over the upsetting die 1:? on the proiection 9, and an other eyelet is then set in the lower portion of the upper and the operation repeated. The construction and operation of the punch. as also the lower set are well lumwu to those skilled in the art and do not require detailed description.

What I have termed the block 01' plate 5 is located on the side of the plate 2 which is toward the top of the sheet as so n Fig. l. the edge of said block 5 which is next the slot being indicated by dotted line 15, Fig. l and it will be clear that said block may be either integral with the part 2 or it may be formedon the work plate of the machine and be integral therewith, or it may as indicated in the drawings, be simply a separate strip or block of proper size having holes therein through which the securing screws 3 may pass. This block is not only thick enough to permit the lower portions of the work to pass under the plate, but also to hold the upper portion of the work high enough upto prevent it slipping 02! over the end of the punch before the feeding movement is completed, and. the plate adjacent the slot supports the upper;
