0J!" PATEBSON, NEW JERSEY, A CURPORATION FArSTENEBfSETTING MACHINE.

Patented Dec. 27, 1921.

Application filed Augmst 5, 1918. Serial No. 248,344.

To all whom it concern e it known that I, J osnrH GoUnDoURN, ai subject of the K' of England, and resident oi' Leicesterjlfeicestershire, England, have invented certain Improvements in Fastener-Setting Machines, of which the fol-` lowingdescription, in connection with the fasteners to the settin mechanism, andhav-` ing, mechanismior ceding the worky step by step. 1

An object of the invention is to provide improved controlling means adapted to control boththe fastener-supplying mechanism and the work-feeding mechanism, either coli lectively or individually, as the case may be.

For purposes of illustration the invention isherein disclosed as` being embodied in an eyeleting machine of which the eyelet-supplying mechanism may be rendered inoperative temporarily, and of which the workfeeding mechanism may be` altered to increase or to decrease the length of the` steps.

. In some cases it is desirable t0 stop the supplying of eyelets while the machine continues to punch holes in and to feed the work with or without a change in the length of the feeding steps; On the other hand it is sometimes desirable to change the length of the feeding steps without discontinuing the `United States No. 1,048,836 granted December 31, 1912 on an application of A. E. "Jerram, but the controlling means shown in .the latter patent would not be suitable for a machine having work-feeding mechanism of the type shown in the aforesaid Pearson atent.

The invention will be best understood trom` a consideration of the following speci` licatlon taken in connection with the accompanying drawing, in which,-

Flgure 1 is a front elevation oit a machine embodying the present invention;

4 `Fig. 2 is a plan view partly in section of the right hand ond of the machine and shows the control mechanism;

Fig. 3 is a diagrammatic view showing the spacing mechanism; and

F 1g. l is a view ol the treadle controlled member.

Reference maybe had to the above-mentioned Jerram latent No. 1,048,836 for a description oi parts not herein fully described but in general such a machine will comprise a punch 10, setting devices 12, a hopper Maand a raceway 16. Movement of the various parts is effected from a power operated` shait 18.

The delivery of tasteners to the setting devices. is effected by means of a spindle 20 irictionally mounted within the upper set 12 (see Fig. 6 of the Jerram patent) and adapted to be projected through the endmost cyelet in the raceway 16 by means of aiinger 22 (sce Fig. 2). It will be noted that the end oil? this linger 22 which projects within the set'12 is beveled at its upper side in order that no harm may result in case the linger is projected into the set at the time the spindle 2O is in elevated position,l but the linger 22 will be pushed aside against the action of a treadle spring 72 to be later described. Locking means comin-is ing a sliding pin 24 and an eccentric 26, operated by means ot a handle 28, are provided for securing the linger 22 in its operative position, that is to say, in the position in which it will expel the spindle 2() dur-ing the retraction oi' the set. A lever 30 having a pin and slot connection with the linger 22 and loosely pivoted upon a verti- 'cal shaft 32 journalcd in a bracket on the machine trame, is provided at one end with a member 311 provided with teeth arranged concentric with the shaft 32 and for a purpose to be later described.

is in the arrangement oit the Jerram pat ent, the spacing oi the eyelets is secured by feeding the work by means of a lateral movementl of a punch lever l0 carrying the punch l0. This lever -lO is mounted -for vertical movement within a iframe 42 which is pivotallymounted at 44- Vfor lateral movement about a pivotal axis. According to the present invention, this lateral movement is effected by transmitting the movement oli' a level` 426, pivoted at l? and operated from a cam lil, through two pivotallyconnected links a8. is in the arrangement ot' the Pearson patent, the path or movement of the connecting point between said linlrs is controlled by m s ot a link 50 which is mounted on a pivot stud 52 carried by an arm 54 ined on the shalt 32 and having a toothed portion in the same plane as the toothed portion 3l ci the lever BO. The length ot the link 50 is equal to the distance between the centers o'l the pivot 52 and the shalt 32.. Manual movement of the arm 5/l to vary the position oi the stud 52 is secured by means ot a handle pinned to the upper end oi' the shaft 32 and movable over a perforated plate into which Vpms 60 may be inserted ior limiting the movement oi" the handle 56. rlhe toothed portion of the arm is also concentric with the shalt 32.

interposed between the toothed portion of the arm 54 and the toothed portion 34 is a pinion 62 meshing with said toothed portions and supported for rotation within the forked end 6l of a rearwardly extending rod 66. This rod is adapted to be manually actuated in one d' 'ection through a bellrcranlr lever'S by means of a rod 70 connected to a treadle or other suitable device (not shown) and in the other direction by a spring 7 2.

r" neither the finger 22 nor the handle 56 is locked in position, the operator, without losing control of the work and while the machine is in operation, may by depressing the treadle cause the forward movement of the pinion 62 to shift both the toothed arm 54 of the spacing mechanism and the toothed portion 34 ot the eyelet controlling mechanism so as simultaneously to increase the spacing between the punched holes and at the same time to withdraw the finger 22 to prevent the ejection of the spindle 20 and hence to prevent the delivery of eyelets to the setting mechanism. It, however, either one of these toothed arms is locked in position or reaches its limiting position before the other, the pinion 62 will roll upon the locked arm and cause movement of the other arm thereby to control that mechanism which is unlocked. Upon release of the treadle, the spring 72 will. cause retraction ot` the pinion 62 and reverse the operation.

It will be understood that, although the invention has been illustrated and described in connection with a particular machine and particular control mechanisms, its use 1s not so limited and it can be applied to other similar machines to effect similar results.
