Specification of Letters Patent.

Patented May 7, 191%..

Application. filed April 21, 1917. Serial No. 163,545.

To all whom it may concern:

Be it known-that I, LOUIS MYERS, a citizen of the United States, residing at Detroit,

provide an improved means for'feeding and carrying the eyelets toward the inaterial to be eyeleted.

It further has its object'to provide a means for receiving and carrying the eyelets, which means will hold the eyelets thereon with a yielding frictional engagement.

It further has for its objectto provide a carrying means which will easily enter the eyelets of varying sizes and carry them to the material to which they are to be applied.

My invention constitutes an improvement upon the eyeleting machine shown and described in my Patent No. 1,174,948, granted March 7th, 1916.

The following is a description. of an embodiment of my invention, reference being 3 had to the which:

Figure 1 is a side view of a machine embodying my invention, part of the face plate being broken away;

Fig. 2 is an enlarged view of the lower front portion of the same;

F ig. 3 is a perspective view of the fastener-supporting springs, and portions of the tracks constituting a magazine;

Fig. 4 is a partial sectional view, showing the set and plunger and the guiding supports therefor;

Fig. 5 is a side elevation and bottom plan view of the radially yielding plunger;

Fig. 6 is a detail view of the blank from which the plunger may be made up by formaccompanying drawings, in

ing{ and swaging.

eferring moreparticularly to the drawings, which show my invention embodied in an'eyeletingmachine, 1 is the frame of an eyeleting machine having a base 2; 3 is an anvil mounted on said base; 4 is a set for insertin the eyelets when fed thereto; 5 is an actuatlng handle having a cam 6 for actuating said set; 7 is a spring for retracting said set and handle; 8 is a magazine for feeding the eyelets, composed of two tracks 8' 8 9 9' are springs at the bottom of said magaend of said set.

zine for receiving eyelets from said magazine and holding them beneath the lower end of said set 4, these springs being so proportioned that as the set 4 descends they are forced apart so asto permit its lower end to pass between and below them. ln the lower end of the set is a plunger 10 having radially yielding prongs, which, when contracted, tends to expand and will expand so as to return to its normal condition. In its normal condition it closely fits the hole in the lower In the construction shown it is free to move upward in said set, and is normally held in the projected positionby spring 11, Within said set, which bears upon the upper end of the plunger. This plunger is preferably made of sheet steel stamped in the form shown in Fig. 6, and then formed into cylindrical shape, and its lower ends slightly swaged inward to produce a shoulder 12 and inwardly rounded surfaces 13 at its lower end. It is then preferably tem pered. This plunger, so constructed, can be compressed radially on all sides, the yielding prongs beingarranged concentrically about the axis of said set and will expand when so compressed.

The springs 9, 9, consist of side plates 14 screwed to the frame at 15 and supporting front plates 16 which lie over the lower ends of the tracks 8, 8 Theupper ends of the plates 16 have inward extensions 17, which when the set 4: is withdrawn from between the plates 16, lie in the path of the eyelets within the magazine 8 and when the set is in depressed position are separated so as to be out of the path of the eyelets. The space between the projection 17 and the set 1- when the punch is depressed, is sufficient to receive one eyelet and one eyelet only.

In the operation of the machine, as the set is being depressed, the lowermost eyelet in the magazine passes downward past the projections 17, so as to fall by gravity to a position below the set and plunger as the set rises and be there supported by the springs 9, 9. As the handle is depressed, the plunger 10 enters the eyelet, and in so doing is slightly compressed radially so as to make a frictional binding engagement therewith.

'A further downward movement of the set 7 Copies of this patent may be obtained for on the bottom'side of the material to be fastened, the plunger 10 retreating within the set so as to permit this punching and crimp ing action. On account of the radial COID- pression of the plunger, the eyelets are positively held and guided toward the material to be eyeleted, and the operation is much more positive and certain than if a solid unyielding plunger was used.

The lower end of the setis preferably beveled slightly at 18 so that the edgesof the. front plates 16 of the springs 9, 9, which contact with the set, can more easily enterbetween the end of the set and the rim of an eyelet carried by the plunger, so as to remove the eyelet on the up stroke of the plunger, as is desirable when the plunger is moved upward before the eyelet has, been forced through the material to be eyeleted. As will be evident to those skilled in the art, myinvention permits of various modifications without departing from. the spirit thereof, or the scope of the appended claims.

What I claimis: I

1. In an eyeletingmachine, the con1bination of a base and anvil carried thereby, springs for supporting an eyelet above said anvil, aset above said springs, and a normally, projecting sheet metal member carried by the lowerend of said set, said projecting member beinghollow and having a plurality of downwardly projecting yielding prongs for entering the eyelet.

2. Inan eyeleting machine, the combination of a base, an anvil carried thereby, springs for supporting an eyelet above said anvil, a set above said springs, and a normally projecting sheet metal member carried by the lower end of said set, said projecting member being hollow and having a plurality of downwardly extending yielding prongs for entering the eyelet, said prongs being arranged concentrically about the axis of said set, the lower ends of said prongs being turned inwardly toward one another.

3. In a fastening machine, the combination of a frame, an anvil carried thereby, eyelet supporting springs located above said anvil, a set having at its lower end a radially yielding member having a plurality of concentrically arranged yielding prongs for en tering the eyelet, means for reciprocating said set, and tracks forming a magazine for feeding fasteners to said springs, said springs each having a face portion overlying a portion of said tracks, and provided with a lateral projection at its upper end and extending continuously from said projection to said plunger.

4. In an eyeleting device, the combination of a support, an anvil carried thereby, a set, and a normally projecting sheet metal member carried by said set, said projecting member being hollow and having a plurality of projecting yielding prongs for entering an eyelet and frictionally holding the same.
