EYELETING-MACHIN E.

, Application filed August 28, 1909.

To all whom it may concern:

Be it known that I, LEWIS F. WEBER, a citizen of the United States of America, residing at Frankfort on the-Main, Germany, have invented certain Improvements in Eyeleting Machines, of which the following description, 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 to machines for setting fasteners, such as eyelets, lacing hooks and the like, in the uppers of boots and shoes, and relates particularly to devices whereby the work may be held firmly during the setting operation of the machine.

Heretofore in eyeleting closed uppersit has been diflicultt'o hold thework during the setting of the-lowest eyelet in'each quarter for the: reason that the junctureojf the vamp, tongue and quarter'sforms a bunch or thick part win the location where the'fpresser foot should engage the workL'fThis thick part constitutes an obstruction' which it is difficult' to pass under a presser foot'of the usual construction and so interferes'with the setting of an eyelet in the required close proximity to the vamp. Even if the thick part is fed underthe presser foot-it affords an uneven and restricted bearing for the latter with the result that the/work is liable to become displaced or twisted in the machine and injured by the punch or sets.

With these conditions in view it is an ob ject of the present inve'ntion to provide a work holding device which shall engage the work over a considerable area, thus preventing displacement thereof, the'location and arrangement of said device being such as to avoid the thick portionin the closed upper and permit feeding the upper to the sets without obstruction.

In feeding a right quarter to the sets the thick portion of the upper, mentioned above, falls at the left ofthe setting position, while in dealing with a leftquarter the thick portion is upon the right side of this point.

An important feature of my invention consists in the provision of a work holding mechanism in which the right quarter is held and guided by a member located upon the ri ht side of the'setting position and the le t quarter by a member located upon the left side.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Serial No. 515,049.

A preferred embodiment of my invention comprises a presser foot consisting of two pivotally mounted parts either of which maybe moved to operative or inoperative positions and locked in either of said positions; The operative position of one part is on the right side of the setting position whereby it is afforded an extensive bearing on the uneyeleted portion of the right upper and the thick portion of the upper lies beyond this part and moves away from it dur ing the setting operation. On the other hand the operative position of the second part of the presser foot is on the left side of the setting position whereby the left quarter is eyeleted with equal convenience.

As herein shown the two parts of the presser foot are so mounted that one may be moved without effecting the'position of the other. To this end the parts are journaled one above another to turn about a vertical axis, the shank of the longer part being offset from its work engaging end so as to clear the shank of the shorter part." An advantage of this construction is that both parts may be moved into inoperative positions in the same verticalplane and therefore occupy, in inoperative position, a location more remote from setting position and more out of the way of the work than would be the case if the two partswere connected. Moreover the independent mounting of each part tends to improve its bearing upon the work when in operative position.

These and other features of my invention will 'be best understood and appreciated from the following description of one embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which,

Figure l is a front elevation of the work holding mechanism showing the upper set and work table, and Fig. 2 is a plan view of the same.

The work table 12 is slotted at 14 to receive an anvil block upon which the punch 10 cuts and to permit the passage of the lower set for setting the eyelets in the work. As shown herein the punch 10 is provided with a clenching or upsetting shoulder and cooperates with the lower setting die in clenching the barrel of a fastener upon the work. At the rear of the work table and mounted for vertical reciprocation upon any convenient part of the machine is the rod 2 carrying upon its upper end the journal member 3. The presser foot consists of two parts 4: and 5' which are mounted to turn upon the journal member 3. Each part of the presser foot has a portion adapted for use with one quarter of a closed upper and is provided with a rearwardly extending portion 8 provided with a spring pressed plunger 6 cooperating with notches in the journal member 3 to hold the parts of the presser foot in one of two predetermined positions. For example, the part 4 is shown in its operative position by the fulllines in Fig. 2 in which position it holds and guides a left quarter, permitting the closed upper to be moved as far to the left'as may be necessary for setting the lowest eyelet near the vamp. The dotted lines in Fig. 2 show the part 4 in its inoperative position where it is entirely clear of the work and which position it occupies while the other part 5 of the presser foot is operative.

It will be apparent from Fig. 1 that the work engaging ends of the presser foot parts lie in the same horizontal plane while the shank of the longer part 4 is bent sharply upwardly so that it may swing over the shank of the shorter part 5 without interference.

For retracting the spring pressed plungers 6 the levers 7 are provided, each being pivoted upon the portion 8 of a presser foot part and having its end so located as tobe within convenient reach of the operator.

Preferably the two parts ofthe pressing members 4 and 5 which are intended toengage the work are conformed to the shape of the slot in the work table, each part extending some distance along the side of the slot and across one end thereof so as to en gage the work over a considerable area.

The rod 2 which carries thetwo parts of the presser foot has suitable connections (not shown) with mechanism for intermittently lifting-it to permit the work to be fed and also with a treadle whereby the presser foot may be raised for the insertion of the work, all of which mechanism is well known in the art and requires no particular description in this place. i

The operation of the work holding device will be clear from the foregoing description. In practice the two ,quarters are eyeleted with their inside uppermost, the part 5 of the presser foot being operative during the eyeletting of the right quarter and being moved by the operator into its inoperative position when the left quarter is to be eyeletted and vice versa. In moving one of the presser foot parts to operative or inoperative position it is necessary only to press the appropriate finger lever 7 and then swing the presser foot part toward the desired position. l/V hen this is reached the spring locking pin enters the propernotch in the journal member and so automatically locks the part in position.

Having described my invention and illustrated a preferred embodiment thereof, what I claim as new and desire to secure by Letters Patent is l. A machine of the class described having, in combination, fastener setting devices, 'a'work supporting table, and a presser foot having two independently movable bearing members either of which may be moved into an noperative position out of engagement with the work, one of the members being adapted for use with one quarter of an upper and the other member with the oppo'site quarter.
