EYELETING-MACHINE.

Application filed June 28, 1910.

To all whom it may concern:

Be it known that 1, ROBERT B. SMITH, a citizen of the United States, residing at Stoughton, in the county of Norfolk and State of Massachusetts, 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, for example, as eyelets and the like, and more particularly to machines for handling and operating upon fasteners which are non-circular in shape.

It is frequently necessary to setfasteners which areelongated and ,difiiculty has been experienced in handling these fasteners and delivering them from the magazine to the raceway of an automatic machine.

The general object of the invention is to provide a machine for supplying and setting such elongated fasteners or fasteners having more than one barrel, or single fasteners disposed with their barrels side by side.

The machine illustrated in the drawings is particularly adapted to handle fasteners of the type known as twin eyelets. These fasteners generally consist of two barrels similar to those of ordinary eyelets struck out from a single elongated flange.

Heretofore it hasbeen customary to supply twin eyelets by hand to the setting dies in which they were to be clenched. This was partly due to the difficulties referred to above and partly to the fact that no suitable means was known for supplying such eyelets from a raceway to a plurality of dies such as are necessary for effecting the setting of the eyelet.

An important feature of the present in vention consists in a construction whereby fasteners of the character described, or two single fasteners at a time. maybe supplied from a raceway to a plurality of setting dies properly positioned to cooperate to set the fastener delivered thereto.

One preferred embodiment of the invention includes a structure having a plurality of setting dies and a corresponding phirality of upsettin'g dies, the said dies being arranged.- in pairs,- each pair consisting: of

setting die and a cooperating upsetting die. In the machine herein shown such pair comprising a setting die and an upsetting die is arranged in front of another similar pair and the raceway is positioned in line with the setting dies at the rear thereof and may rec procate along the line mentioned.

. The double barreled fasteners lying longitudinally in the raceway as heretofore described, the fastener at the foremost end of the raceway will, when the raceway is brought forward, be presented to the dies with the barrels in proper relation to the said dies to be operated upon thereby. A plurality of spindles mounted within the setting dies, one for each barrel of the fastener, enter the fastener and remove it from the raceway as the latter is retracted.

WVhile I have illustrated a machine for handling twin or double barreled fasteners, it should be understood that my invention is notlimited to'the handling of fasteners with two barrels but may be successfully embodied. in machines which will handle fasteners with any desired number of barrels, which may be designated broadly as multiple fasteners.

The spindles heretofore referred to for entering the barrels of the fastener and removing the latter from the raceway are preferably mounted upon a common base actuated by a single actuating means, such as a spring. This insures that the spindle shall move simultaneously and thus shall onter the barrels of the fastener without difficulty.

Another feature of my invention comprises the provision, in a machine having a raceway for supplying or delivering fasteners, of improved means for retaining the fasteners in the raceway until it is desired to remove one or more for insertion in the work. I preferabl effect the desired result by means of a yielding spring'latch lying above the endmost fastener in the raceway and having its end turned downwardly so as normally to lie in front of said fastener. Such de ice will yield to allow the ready removal of one or more fasteners when desired and immediately return to position to retain the remaining fasteners in the raceway.

Other features of the invention will appear more: hilly in the following description alnd will be pointed out in the appended C lllTlS- In the drawings.Figure 1 is a side cleva-tion. partly in section. of an eyeleting machine embodying the features of my invention: Fig. 2 is a perspective view of a twin eyelet of the type adapted to be handled and set by the illustrated machine: Fig. 8 is a detail, partly in section. showing the arrangement of the po ts in the magazine: Fig. 4 is a detail plan view of the forward end of the raceway: and Fig. 5 is a section on the line 5-5 of Fig. 4;.

Referring to the drawings, 2 designates a base or suitable support upon which the frame 3 of the machine is mounted. The frame 3 is formed with a forwardly projecting upper portion 4 in the end of which are mounted the upsetting dies 6 for upsetting or clenching the eyelet barrels on the work.

6. 6 represent two upsetting dies mounted within the head 7 of a holder 8. The said holder 8 is secured in a suitably formed a1 erture in the end of the frame 4 by means of a set screw 9 and is stationary during the operation of the machine.

A plunger 10 is mounted to reciprocate vertically in a guideway 11 formed in the lower'part of the frame of the machine, the axis of the said plunger coinciding with that of the holder 8. The plunger 10 is bored out as shown at 12 to receive and hold rigidly a die holder 13 in which are mounted setting dies 14. 14. Each of the setting dies is centrally drilled to allow the passage of a spindle 15. The die holder 13 is also drilled in line with the holes drilled in the setting dies so that the spindles 15 loosely pass through both the setting dies and their holder. The spindles 15 are both rigidly mounted at their lower ends in a button 16 which is freely slidable vertically within the recess 12 below the die holder 13. \Vithin said recess is also located a spring 17 which normally presses the button 16 and the spindles carried thereby into their uppermost position, as shown in Fig. 1. The upsetting die holder 8 is mounted so that the upsetting dies 6, 6 lie one in front of the other, or, in other words. the said dies lie in a line extending from the front toward the rear of the machine. The setting dies 14, 14 are mounted to register respectively with their corresponding upsetting dies 6, 6 so that when a fastener, such as that illustrated in Fig. 2, is placed upon the lower or setting dies and the latter are moved toward the upsetting dies 6, the said upsetting dies will upset or clench the ends 19 of the barrels of the fastener 18.

The mechanism for imparting a reciproeating movement to the plunger 10 is connected to the lower end thereof and may be of the same character and construction as that illustrated in U. S. Letters Patent No. 898,729, granted September 15, 1908, to J. F. Davey. V

In order to supply the fasteners 18 to the sets a magazine 20 for holding thefasteners and a raceway 21 for receiving them from the magazine and delivering them to the dies are provided. Within the magazine is an agitator 26 which oscillates and keeps the fasteners constantly moving. The magazine and raceway aremounted to reciprocate in the manner disclosed in the U. S. Patent above referred to. In order to effect separation of eyelets or fasteners in the magazine and permit their delivery therefrom to the raceway, ports 22 are provided in a po tion of the periphery of the magazine. These ports are separated from each other by studs 23 which are cylindrical in form'and are so 7 spaced that the fasteners 18 can only pass lengthwise therehetween one at a time and with the barrels of the fastener upward. By reason of the cylindrical formation of the studs 23 the fasteners, while passing between the studs, are free to turn either upwardly or downwardly to bring their longitudinal axis into alinement with their subsequent direction of movement in the raceway 21. Any danger of blocking or choking of the ports or of the raceway is thus eliminated and a sufficient number of eyelets is delivered to the raceway to supply the needs of the machine. An inspection of Fig. 3 will show that in passing throughthe ports 22 of the magazine the eyelets can turn in either direction. This facilitates their entrance into, and proper arrangement within, the raceway.

The raceway is inclined downwardly and forwardly as illustrated in Fig. 1 and when in its delivering position intersects the axis of the rearmost dies and terminates substantial-ly in line with the axis of the foremost dies. At the forward and lower end of the raceway a spring latch or detent 24 is mounted by-means of a screw 27, or other suitable securing means. The forward end of the latch is deflected toward the center of the raceway as shown in Fig. 4 so as to lie above the endmost fastener in the raceway. The tip of the latch 24 is turned downwardly as shown at 25, the downwardly turned portion lying in front of the foremost fastener in the raceway. as clearly illustrated in Fig. 5. The latch 24 normally retains the supply of eyelets in the raceway but will yield to allow the removal of an eyelet by the spindles 15 when desired, immediately moving back into position in front of the next preceding eyelet in the raceway.

By constructing the latch so that it shall lie above. and extend down in front of, the eyelet which it engages in the raceway. an important advantage is secured in handling eyelets having anelongated outline inas much as it is necessary that such eyelets be presented to the sets in proper angular position with relation thereto. The latches heretofore used in automatic eyeleting machines engage the side of the eyelet and have a tendency to rotate the same as it is taken from the raceway. This is immaterial when circular fasteners, such as round eyelets, are being used but becomes a source of difficulty when an elongated or double barrele'd fastener is to be handled. lVith my improved device, the ends of the spindles 15 may, after passing through the barrels of the fastener, engage the latch and lift it slightly out of engagement with the fastener so that there is no tendency whatever to rotate the fastener as it is taken from the raceway and it is therefore easy to position the fastener properly and accurately upon the setting ies.

In the operation of the machine the agitator 26 keeps the fasteners in the magazine in constant movement and a sufiicient number of them is delivered through the ports 22 always to maintain a supply in the raceway. As the plunger 10 is moved upwardly, the spindles 15 enter the barrels of the foremost eyelet in the raceway. The raceway is then moved rearwardly and the eyelet which is held upon the spindles 15 is disengaged from the raceway, the latch 2-1 immediately dropping down in front of the next fastener and preventing its escape. The plunger continues to move upwardly and the fastener carried by the setting dies 14 mounted upon said plunger is inserted in the work and upset or clenched against the upsetting dies 6, the downwardly projecting portions of which depress the spindles 15 against the tension of the spring 17. In the return of the plunger to its lowermost position the raceway is again moved forwardly in order to bring another fastener into position to be received upon the spindles of the setting dies in the next operation of the machine. It should be understood that the number of setting dies 14 and of the corresponding upsetting dies 6 is not limited to two but is only determined by the number of barrels 19 upon the fastener to be handled by the machine.

Throughout this specification and in the following claims I use the term setting die to refer to that die which receives the fastener from the raceway, and the term upsetting die to refer to the cooperating die which upsets or clenches the barrel of the fastener upon the work. I also use the term pair to define a setting die and its cooperating upsetting die. For example, a setting die 14 and its cohperating upsetting die 6 form a pair in the sense in which that term is to be understood. The line in which the raceway 21 reciprocates extends from the front toward the rear of the machine and is coincident with the plane containing the setting dies 14: and the upsetting dies 6, that is to say, the raceway is arranged to reciprocate in the direction of the line joining the dies 14 which receive the fastener from the raceway.

Having thus fully described my invention, what I claim as new and desire to secure bv Letters Patent of the United States is 1. A machine for setting fasteners having, in combination, a plurality of setting dies, a corresponding plurality of oppositely disposed upsetting dies, and means for successively bringing fasteners into alinement with and between all the dies, said means comprising a raceway movable to and from a delivering position in which it intersects the axis of one setting die and terminates substantially in the axis of an adjacent die.
