EYELETING-MACHINE.

Specification of Letters Patent.

Patented July 19, 1910.

To all whom it may concern:

Be it known that I, JAMES A. DUNPIIY, a citizen of the United States, residing at Groton, in the county of Middlesex and Commonwealth of lifilassachusetts, have invented certain Improvements in Eyeleting- Machines, of which the following descrip tion, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures;

This invention relates primarily to eyeleting machines and more particularly to those elements in such machines which guide the work while it is being fed and which contribute to maintain the work in proper position when it is at rest.

The invention is particularly applicable to work controlling or positioning means of the type described in copending application for Letters Patent of the United States, Serial No. 329,722, filed August 8, 1906, and the invention is intended primarily to provide .a modification of the construction illustrated in said co-pending application for the purpose of adapting it to what is known as blind hook work.

As herein described, the present invention is embodied in a machine well known by those acquainted with the art as the duplex eyeleting machine which, for the purposes of the present specification, may be regarded as having substantially the construction shown in United States Letters Patent No. 683,488, dated April l, 1901 or of British Letters Patent N 0. 20,754, dated September 23, 1902. However, nothing herein contained is to be construed as limiting the present invention in the scope of its appli cation to use in connection with the machines of said patents or of said co-pending application since, as will be obvious, the invention may be applied to various other types of machines for setting eyelets, lacing hooks and like articles.

In blind hook work, as carried on in I the manufacture of shoes, the barrels or eyelet portions of the lacing hooks upon the inside of the shoe fly are covered by a facing or reinforcing strip of material secured, usually by stitching, at the edge of the fly so as :to cover the clenched ends of the barrels of the hooks. When a shoe fly is to be provided both with such blind hooks and with eyelets, it is the custom to set the hooks, then to secure the facing along the entire length of the front edge of the fly and finally to set the eyelets with their barrels extending through and clenched on the inside of the facing. It is desirable also, in order that a satisfactory spacing may be obtained, to set the eyelet at the lower end of the fly first and the eyelet next to the lowest hook last.

Hence, it is necessary that the construction of the eyeleting machine, and particularly of the work-controlling means, shall be such that the presence of the hooks in the shoe fly will not prevent the placing of the eyelets at the desired locations in the fly.

A principal object of the present invention is to provide in an eyeleting machine work-controlling means which shall be simple and inexpensive in construction and not likely to get out of order but which, also, shall properly position the work and make it possible to set an eyelet as closely as may be desired to a previously inserted hook or any other projection upon the work.

With the attainment of this object in view, the present invention comprises the provision in an eyeleting machine of workcontrolling means which includes a presser foot bearing continuously upon the work and provided with an uninterrupted opening in the direction in which the work is fed to permit the entrance into, or the passage through, the presser foot of a projection upon the Work, such as a lacing hook, so that an eyelet may be set at any desired dis tance from a previously inserted hook. It is preferable, moreover, to provide a presser foot which shall bear upon the work as closely as possible to the line in which the eyelets and hooks are being inserted. Accordingly, another object of the invention is to provide a construction of presser foot which will permit it to bear upon the work close to the line referred to, but which will not interfere, through engagement with a hook, with the positioning of the work so that an eyelet may be inserted close to a hook. For the purpose of attaining this object, a presser foot is provided, according to this invention, with a work-engaging surface and with a recess above said surface, the arrangement being such that a hook may they occupy pass into or through the presser foot preferably with the bill or head of the hook overlapping the work-engaging surface of the presser foot and entering into the recess in the presser foot.

In addition to the features already referred to, the present invention further comprises various arrangements and combinations of parts, and certain details of construction which will be hereinafter described in detail and pointed out in the claims.

Referring to the accompanying drawings which illustrate a preferred embodiment of the invention :Figure 1 is a plan view of such parts of an eyeleting machine as are related to the present invention; Fig. 2 is a side elevation of the work-controlling means, the two flies of a shoe being shown as partially inserted thereinto; Fig. 3 is a view similar to Fig. 2, showing one fly in the place which it will occupy while eyelets are being inserted, a hook being shown within the one presser foot illustrated; Fig. 4 is a view corresponding to a portion of Fig. 1, the parts being shown in eyelet-setting position; Fig. 5 is a View similar to Fig. 4 but with the parts shown in the position which at the end of the work-feeding movement; and Figs. 6 and 7 are enlarged sectional views taken respectively upon lines aa, Fig. 1, and b?), Fig. 5, illustrating how the hooks may enter and pass through the presser foot.

As illustrated, 2 indicates a part of the frame of an eyeleting machine of the type hereinbefore referred to. A bracket 4, projecting forwardly from the frame, carries the guide plate 6, the edge gages 8 upon opposite sides of the plate, and the presser feet to which the present invention more particularly relates and which will hereinafter be described in detail. As in the prior machine mentioned, the edge gages may be formed in one piece adjustably supported upon the guide plate and the guide plate may be provided with a rack 10 meshing with the sector gear 12 arranged to be partially rotated by a link 14 and connections, thus providing for the spread of the eyelets, z. c.:their spacing from the edge of the work.

16 designates what is commonly known as the feed frame which supports the anvil plate 18 provided with a punch anvil 20 with which a pair of punches 21, one of which is shown in Fig. 6, cooperate to form holes in the shoe flies F for the reception of the eyelets. The anvil plate 18 carries also a two faced setting die 22 with which a pair of sets 24, of which one is shown in Fig. 7 coiiperate to set the eyelets and to feed the work. The feed frame 16 is pivotally mounted upon a short shaft 26 carried by a cam-actuated bell crank lever 28. The lever is moved by its cam at the proper point in the cycle of operations to retract the anvil plate from the position shown in Fig. 1 to that shown in Fig. 4 so that after a hole has been punched in the shoe fly by punch 21 a setting die 22 as well as its cotiperating set 24 is brought into alinement with the punched hole, whereupon an eyelet is fed into position between the setting devices and set. Then the anvil plate and cotiperating devices are moved to feed the work, after which the parts return to initial position. All of these parts are or may be substantially the same in construction as in the prior machine referred to and they may be actuated in substantially the same manner so that the above description is sufficient to make clear how the present invention is to be embodied in an organized machine.

Referring now to the particular parts which embody the present invention, 30 represents two presser feet, one of which with an edge gage 8 is, as indicated in Fig. 2, arranged above and the other below the guide plate 6., At its forward end, each presser foot is provided with a block 32 narrower in width than the main part of the foot and having a rearwardly extending toe 34 which is relatively thin so that a recess 36 is formed between the toe and the main body of the presser foot. At its rearward end the presser foot is provided with a block 38, the lower surface of which is located preferably slightly above the plane of block 32 so that the edge of the fly will not chance to engage the end of block 38, instead of edge gage 8, as it is being inserted (see Fig. Each presser foot is supported upon a spring plate 40 secured at one end by two screws 42 to an edge gage 8 and at the other by a screw 44 to the presser foot, a pin 46 upon the edge gage extending through a slot in the spring and another pin 48 upon the presser foot extending through a hole in the spring so that the presser foot is maintained in proper lateral position with reference to the other parts. The spring 40 exerts a pressure upon the presser foot to maintain the blocks 32 and 38 in continuous engagement with the fly F after it has been inserted into operative position. When constructed and arranged as shown in the drawings and particularly in Fig. 3, the presser foot exerts its greatest pressure upon the work substantially at the extremity of toe 34 and in or near the line in which the eyelets and hooks are inserted while the block 38 of the foot bears upon the edge of the work. It will be seen from Figs. 3, 6 and 7 that through the presser foot the toe 34 extends into the neck or recess of the hook while the bill of the hook enters the recess 36. With a presser foot constructed in this inanner and coeperating as described with the guide plate 6 and the edge gage 8, a continwhile a hook is passing uous pressure is exerted upon the fly so as effectively to hold the work while it is at rest and guide it while it is being fed.

Figs. 1 and 6 represent the parts of the machine in the positions which they occupy at the beginning and at the end of a cycle of operations. lVhen the last eyelet E-that is, the eyelet next to the lowermost hook H in a shoe flyis to be set, the hole is punched with the guide plate 6 and anvil plate 18 in the positions shown in Fig. 1; then the anvil plate is retracted to the position shown in Fig. 4 and a pair of eyelets set, after which the anvil plate and the setting devices are swung to the position indicated in Fig. 5, thus effecting the feed of the work; the sets 24 are then retracted and the anvil plate is returned to its initial position shown in Fig. l, the work being continuously retained in proper position by the yieldingly acting work-controlling means. The path of the setting die 22 in the anvil plate during this sequence of operations is indicated diagrammatically in Fig. 5. At the beginning of the operation of setting this last eyelet E, the lowermost hook H, shown. at the left in Figs. 6 and 7, will occupy the position of the hook H shown at the right in these figures and, with the spacing shown, it will be just within the presser foot 30. When the work is fed as just described this hook H will be carried to the left, its bill passing through the recess 36 and the toe 34 of the foot pressing upon the work close to the axial line of the hook, and finally the next succeeding hook H will enter the presser foot as shown in Fig. 7. Because of the pressure exerted by the presser foot, the position of the work will not be changed while the anvil plate and connected parts are returning to their initial position. As the machine comes to rest, the work and machine parts will occupy the positions indicated in Fig. 6 and it will be seen that by reason of the reduced width of the parts 32, 34 of the presser foot the work can be withdrawn in a straight line from the machine and will not have to be moved laterally in order that said parts will not interfere with a hook.

While applicant for the purpose of fully describing and illustrating his invention has explained in detail a specific construction in which he contemplates embodying the invention, it is to be understood that the invention is not limited to the exact construction shown, but may be embodied in other forms without departing from the scope and essence of the invention as defined by the claims.

Having described my invention,what I claim as new and desire to secure by Letters Patent of the United States is- 1. In an eyeleting machine, the combination with eyelet setting devices, of workcontrolling means, comprising a guide plate and a presser foot between which the work is held, said presser foot being provided,

with an uninterrupted opening in the direction in which the work is fed to provide for the entrance of a projection upon the work into the presser foot, and means acting through the presser footto maintain a continuous pressure upon 'the work.

2. In an eyeleting machine, a presser foot provided with work-engaging surfaces having an uninterrupted opening between them for the entrance or passage of a projection upon the work, said surfaces being arranged to bear upon the work at separated points, one of which is approximately in the line in which eyelets are to be inserted, and means acting through the presser foot to maintain a continuous pressure upon the work.

3. In an eyeleting machine, a presser foot provided with a work-engaging surface and with a recess above said surface adjacent the line in which eyelets are to be inserted to permit the setting of an eyelet as close as desired to a lacing hook previously inserted in the work.

4. In an eyeleting machine, a presser foot constructed and arranged to bear continuously upon the work during the operation of securing an eyelet in place and provided with a recess to receive the bill of a lacing hook and with a projecting part to extend into the neck or recess of the hook.

5. In an eyeleting machine, the combination with eyelet setting devices and workfeeding means, of work-controlling means, comprising a guide plate and a presser foot between which the work is held, said presser foot being provided with a work-engaging part which has a relatively thin toe arranged to bear upon the work close to the line in which eyelets are to be inserted, the presser foot beyond and above said toe presenting an opening for the passage of lacing hooks through the presser foot.

6. In an eyeleting machine, the combina tion with eyelet setting devices and work feeding means, of work-controlling means, comprising an edge gage, a guide plate and a presser foot, the presser foot being provided wit-h a work-engaging surface to bear upon 'the work at the side of the line in which eyelets are to be inserted opposite the edge gage and being provided also with an opening between its work-engaging surface and the edge gage and being recessed above said surface to permit the passage of lacing hooks through the presser foot.

7 In an eyeleting machine, the combination with eyelet setting devices and work feeding means, of work-controlling means, comprising a guide plate, presser feet arranged on opposite sides of the guide plate between each of which and said plate work is held under yielding pressure, each presser presser foot extending a guide plate and a transversely 'to the line from said edge gage of feed, said presser width adjacent the edge gage than at its outer end.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
