FASTENER-SETTING MACHINE.

- Specification of Letters Patent.

Application filed May 22, 1916. Serial No.'99,223.

To all whom it may concern:

Be it known that I, ALBERT E. HUDSON, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Fastener-Setting 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 machinesfor setting eyelets, hooks or similar fastening devices in sheet material. 1

7 An object of'the invention'is to provide a machine of simple construction Which shall be accurate and. reliable in its operation and adapted for a wide range of utility. To this end an important feature of the invention resides in operating mechanism of a novel construction, the character of which will be disclosed .in detail hereinafter.

In one of its aspects the invention contemplates improvements in the machine of United States Letters Patent No. 1,244,430, resulting from an application of John F. Davey, Serial No. 816,832,.filed Feb. 5,1914. In that machine there is employed a power driven setting die. and a punching member arranged to be operated manually preliminarily to the setting operation. The present invention contemplates, as one feature, power driven mechanism for operating such punching member.

These and other features of the invention will be best understood and appreciated from thefollowing description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which, 7 q

Figure 1 is a view of the machine in side elevation; V

Fig. 2 is a view on an enlarged sca-leof the hopper: and associated mechanism, shown partly in section;

Fig. 3is a view in elevation .of the side of the machine opposite to that shown in and I 7 V Fig. 4 153a fragmentary view in frontelevation of portions of. the raceway operating mechanism;

The machine: frame 21s provided with r 5r bearin 's foramain s'haftfi, carrying a driving pu l'ey 4. Glutch'nieclianism, not'shown,

is provided for engaging and disengaging the driving pulley 4 and the shaft 6. The frame is provided with a removable lower aw held in place by attaching bolts and carrying a stationary upsetting and punchlng tool 10. When it is desired to operate upon work of special character, a lower jaw of appropriate shape may be substituted for that herein shown. I

The upper portion of the frame 2,is provided with vertical bearings .for a plunger 12' which carries at its lower end the upper or eyelet inserting diel4. Theplunger 1'2 Patented 001;. 21, 191 9.

is connected at itsupper end through a short d link to the forward end of anoperating lever 16. The lever 16 is rigidly secured to a transverse shaft 18 which is journaled in bearings formed in the machine frame, thus k forming the fulcrum of the lever 16. At its rear end the lever 16 is connected to the upper link 20 of a pair of toggle links. The

lower link 22 is pivotally mounted upon the stud 52 set, in the machine frame and is oscillated by an eccentric rod 24 which,in

turn, is operated by an eccentric 26 fast on the shaft 6. In the stopped: position of the machine the eccentric 26 occupies its forward position so that the toggle links 2022 are held in a broken condition. When the machine is started, the eccentric rod 24' is moved rearwardly and the toggle links; straightened, occupy ng in this condition a position substantially parallel to the path of the die 14. 7

Eyelets are suppliedto the. die 14 by a raceway 30 pivotally mounted upon the spin-.

dle 32 which is retained between a pair of ears formed on the frame 2 as shown in Fig. 3.. The raceway normally occupies a position in which the endmost eyelet is maintained in line'with the die 14. 'Whenthe die has been lowered sutliciently to engage the eyelet with its spindle, the raceway is swung outwardly by a trainjof mechanism operated from the lever 16. As herein shown, this mechanism includes a cam bar 36-having a beveled upper end arranged to v be projected betweena roller 34' on the race way SO and a' roller-35 journaled ona part l I of the stationary frame. The cam'bar36 is connected at its lower end with a lostrnotioln connection tothe short 38 fastftoagrock' shaft 40; journaled in -th maehine]f me. r

The rock shaft 40"PeSses through tlie frame and is provided at its opposite end with a second arm 42 connected to the lever 16 by means of a vertically disposed link 44. It will be apparent that when the lever 16 is moved to depress the die 14, the cam bar 36 will be elevated by the mechanism above described and the lower end of the raceway will be swung out of the path of the die 14. The depression of the bar 36, allowing the return of the raceway, will be delayed because of the lost motion connection between said bar and the arm 38. The omission of such an arrangement would allow the raceway to strike and frequently to break the spindle used for threading the endmost eyelet.

The raceway 80 carries at its upper end a hopper 84 from which the eyelets are supplied to the raceway. WVithin the hopper is disposed an agitator in the form of a brush 82 fast upon the upper end of a shaft 7 8 which is secured at its lower end to a crank arm 7 It will be understood that the agitator is oscillated to cause the eyelets to pass outwardly through the ports of the hopper to the raceway 30. To this end an operating arm 72 is loosely mounted upon the shaft 78 and means are provided for detachably locking the arm 72 to the crank arm 7 4. As herein shown, a spring finger piece 76 is arranged in a boss formed on the outer end of the crank arm 74 and a corresponding socket is provided in-the loose arm 72. The arm 72 is continuously oscillated by the power of the machine through the bell crank lever 70 pivotally mounted on the frame and connected at its upper end through a pin 71 with a slot in the arm 72. When the arms 72 and 74 are connected by the finger piece 76, the movement of the bell crank lever 70 is transmitted to the agitator brush as an intermittent oscillation. In case it should be desired, however, to operate the agitator brush while-the machine remains at rest, as for filling the raceway, the finger piece 76 may be retracted whereupon the agitator brush is free to be oscillated or rotated manually by the crank arm 74. In Fig. 1 the arms 72 and 74 are shown as connected, as in the usual operation ofthe machine. In Fig. 2 the finger piece 76 is shown as retracted and turned so that it is maintained in an inoperative position leaving the agitator brush free to be turned by the crank arm '7 4.

The punching operation is effected by forcing the workdownwardly upon the pointed portion of the combined punching and upsetting tool 10. As herein shown this is effected by a perforated punching member 56 mounted in the forward end of an arm 50, pivotally mounted upon the stud 52 before mentioned. The punching member is operated through a pair of toggle links 58- and 60, the upper of which is rigidly secured to one end of the journal shaft 18 of the lever 16, and the lower of which is connected to the arm about mid way between its axis and the tool 10. In the stopped position of the machine the toggle links 586O are maintained in a broken condition with the punching member 56 elevated above the point of the punching too]. When the machine is started the lever 16 is rocked, the toggle 58 60 straightened and the punching member 56 forced downwardly over the point of the punching tool. This operation carries the punching member 56 downwardly a sufficient distance to permit the upsetting operation to take place between the body of the tool 10 and the die 14. If desired the member 56 may be made in separable sections as in the machine of the application above mentioned. In order to strip the eyeleted work from'the tool 10 a spring stripping member 51 is secured to the under side of the arm 50 and this member is elevated sufficiently before the machine comes to rest substantially to dis engage the work from the tool 10.

The machine has been hereinabove described as intended for setting eyelets in sheet material but it will be understood that. with changes in the fastener supplying and setting instrumentalities appropriate for the accommodation of other fasteners, the machine may be employed for work of a different character.

The operation of the machine will be apparent from the foregoing description but may be briefly outlined as follows:

The work is presented between the strip ping member 51 and the punching member 56 with the point at which it is desired to set the eyelet in line with the point of the punching and upsetting tool 10. The machine is then started whereupon the lever v16 is rocked through the toggle links 2022.

The punching member 56 is immediately depressed forcing the work upon the pointed end of the tool 10. The inserting die 14 having received an eyelet from the raceway follows downwardly inserting the eyelet in the hole previously formed in the workand in its continued movement clenching the barrel of the eyelet against the upsetting surface of the tool 10. Meanwhile the raceway has been moved to an inoperative position where it is maintained until the conclusion of the setting operation. The lever 16 is then rocked in the opposite direction and the various parts of the machine returned to their initial positions while; at the same time, the stripper 51 lifts the eyeleted work from the tool '10. The return of the raceway is, however, delayed until the die 14 and its spindle are well out of its I claim and desire to secure by Letters Patent of the United States is:
