To all whom it may concern:

Be it known that 1, WILLIAM HUGHES, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented certain Improvements in Eyeleting-Machines,of which the following description, in Connection with the accompanying drai'vin gs, is a speoi fica tion, like reference character-son the drawings indicating like parts in the several fig ures.

This invention relates to machines for set ting fasteners such as eyelets insheet material and one of its objects is to provide an improved machine by the use of which blind or invisible eyelets may be set the uppers of boots and sh'oes- In setting invisible eyelets in a shoe'npper' the outer part of the upper is perforated and the eyelets are set in a part of the Min-- ing, or facing stay which is stitched to the lining, in register with the holes so punched. In the finished shoe, therefore, nothing is visible but a series of perforations through which the lacing passes; These perforations are relieved from the strain of the lacing and kept from pulling out of shape by the invisible eyelets set in the material directly beneath them. k v

In machines for setting blind of invisible eyelets it is customary to employ a combined punching and feeding tool to perforate both portions of the upper and then feed the upper by the punched hole. While the eyelet is being set in one part of the upper the other part is pushed upwardly upon the tool where it will be out of range of the setting instrumentalitiesi I have discovered that it is important to limit the movement of this part of the upper upon the tool, as the tool must be promptly withdrawn at the conclusion of the s'ettingopeia tion and its withdrawal is delayed if the part of the upper is passedupwardly upon the tool farther than isneessary. An iinportant feature of the present invention eon-1 sists in means for limiting the movement upon the punching tool of the part of the upper in which the eyelet is not set.

As herein shown a thin separating meniher is employed to separate that part or the upper which is to be pinched only from that part which is tobe pnn'ched and eyelete'd. Another feature of the invention consists in means for supporting or reinforcing the Work separating member during that part of the cycle of the machine when this member would otherwise be likely to become bent or distorted. An advantage resulting from the employment of such su -s porting means isthat the separating member may take the form of plate and may be made thinner than otherwise so that its insertion between the layersof the work is' facilitated.- The employment of athin plate rendersit possible to locate the upsetting die and set the eyelets close upto a line of top stitching. This improves the accuracy of the work and also permits the employment of the machine with less disturbance to the usual stitching room system than would be the case if it' were necessary to eyelet the upper before it had been topstitched.

Aks herein shown the same element is utilized for limiting" the upward movement of the shoe upper part upon the punching and feeding tool and for supporting the work separating member, but itwould be within the scope of the invention to employ distinct elements for these differentfunctions.

While the supporting and limiting means maybe of any desired construction; in the illustrated embodiment of the invention, their functions are supplied by a part of the presser foot; This is an advantageous con struction because it utilizes parts of themachine already available, economizes space and positions the suppo'rting' means; properly with respect to the Work separating plate. This construction; accordingly, constitutes stillanoth'er' feature of the invention;

These and other features of the invention will behest understood and appreciated from the following description of a preferred eInbodiifient thereof selected for" purposes of illustration and shown in the accompanying dr wings,- in which Figure 1 is a view in perspective of so much of the" Ina-chine as is neees'sary' te understand its operation;

having invisible eyelets set therein.

-The invention is herein shown as embodied in an eyeleting machine of the type disin Letters Patent of the United States No. 686,928, granted November 19,

1901. As in the machine of said patent,-

the transversely movable head 2 carries a punch 4 which is arranged to be forced downwardly against a cutting block 6 toperforate the .work and then to be moved laterally to feed the punched work into alinement with the setting dies. The lower setting die 8 is arranged to pick off the lowermost eyelet in a raceway and carry it upwardly inserting its barrel through the perforations in the work.

Secured to the work table 6 is a thin projecting plate 10 which carries on its lower face the upsetting die 12, the latter being disposed in alinement with the path of the lower die 8. The die carrying plate 10 is made of thin material and the thickness of the die itself is reduced to a minimum, so that it may be easily inserted between two partially attached layers of sheet material, such as the lining and theouter portion of a shoe upper, without disturbing their normal superposed relation; The plate is provided with a longitudinal slot 11 which extends from a point above the cutting block 6 toward, but not to, the setting position. The die carrying plate is offset between the ends of the slot 11 so as to permit the end of the punch, when moving in the feeding operation, to pass out of the slot 11 and just clear the back of the plate. noted that a portion of the punch remains in the hole in the outer layer of'material while the eyelet is being set in the under This is advantageous because the work is thus held positively against displace ment and a perfect registration of the hole with the eyelet is insured. At its extreme end the plate 10 is provided with a pair of oppositelyextending projections or cars 14.

.The machine is provided with a loopshaped presser foot 16which is rigidly secured to theupper end of a vertical rod 18 normally urged downwardly by a stiff compression spring 20 so that the presser foot is held yieldingly' against the work and on the table 6." Secured to the lower side of the presser foot adjacent to the setting pos1- tion is a plate 17 recessed at one side or m'adeU-shaped to accommodate the punch' and disposed with its sides overlying-the ears 14 of the plate 10. One purpose of the 7 plate 17 is to reinforce the die carrying plate 10 at points adjacent to' the settingposition,

this being also the point-at which the punch is retracted from thework. j Anotherpur It will be pose of the plate 17 is to limit the movement upwardly upon the punching tool of the outerportion 32 of the shoe quarter.

' After the setting operation the plate 10 acts as a stripper for the punch by holding down the lining and incidentally the outer portion of the quarter which is stitched thereto when the punch is elevated.

A pivoted arm 22 is provided at the rear of the work table 6 and is equipped with an edge gage 28 by which the distance of the eyelet from the edge of the work is determined in the usual manner. The arm 22 is connected beneath the table 6 to a hand lever 24 by which the edge gage may be swung forwardly or rearwardly to vary the spread of the eyelets from the edge of the lacing slit.

In operating the machine the shoe quarter is positioned on the work table 6 with the lining 30 and attached stay, if one is used, beneath the die carrying plate 10, and the outer portion 32 of the quarter above the plate 10. The point at which the first eyelet is to be set being located beneath the punch, the machine is set in operation. The punch descends passing through the slot 12 and perforating both the lining and outer portion of the quarter and then moves later- .ally drawing thelining along the lower side of the plate 10 and the outer portion of the quarter along its upper surface. The punch A remains in the perforation in the outer portion of the quarter throughout the feeding and setting operation but the lining is moved downwardly off the punch-when it encounters the downwardly bent portion of the plate 10. The feeding movement of the punch ceases when the perforation in the lining has been brought vertically above the lower setting die, the end of the punch remaining in touch with the back of the plate 10 above the upsetting die 12. At the end of its feeding movement the punch is partially surrounded by a recessed plate 17. The lower die 8 is then elevated forcing the eyelet through the perforation in the lining and clenching it againstrthe upsetting die 12 while the latter is backed up by the punch reaching in through the hole in the outer part of the quarter. about the same time the presser foot, which has been elevated during the feeding movement, is lowered upon the work." The punch is then moved upwardly while the plate '10, which is necessarily flexible on account of its extreme thinness, is maintained in position and held initial position whereupon the' cycle ofoperationsmay be repeated.

Having thus described my invention, 1
