Application filed April 9,

This invention relates to protecting devices for use on eyeleting and like machines and the primary object is to prevent operation of the machine until the material is properly located thus preventing injury to tached to machines of ordinary construction without requiring alteration of such machines.

A selected embodiment of the invention is illustrated in the accompanying drawing,

" and therein,

Fig. 1 is a perspective View of an eyeleting machine embodying a preferred form of construction of our invention;

Fig. 2 is a view partly in vertical section and partly in elevation looking in at the left hand side of Fig. 1; and

Fig. 3 is a sectional view taken substantially on the line 33 of Fig. 2.

In the drawing, 1 indicates the standard of an eyeleting machine having arms 2 and 3 extending therefrom and including a base 4. At the end of the arm 2 is a sleeve 5 having a plunger 6 mounted for vertical reciprocation therein. At the lower end of the plunger 6 the top set 7 is mounted which set includes a locating pin 8 having a head 9 arranged. in a recess 10 in the set 7 in which recess a spring 11 is mounted which acts on the head 9 to urge the pin 8 outwardly of the end. of the spindle. At the outer end of the arm 3 a socket 12 is formed having an axial opening 13 therein, into the lower end of which opening the locating screw 14 is extended. The bottom set 15 includes a stem extended through a reduced portion of the opening 13 into engagement with the inner end of the locating screw 1 At the upper end of the socket 12 is a holder 16 for the bottom set 15. The sets 7 and 15 are ar ranged in vertical alinement and when the plunger 6 is moved downwardly the eyeleting operation is carri d out by these sets in the manner well understood, the material to be operated on having been previously disposed between these top and bottom sets.

drive shaft 17 is journaled in the standard I 1 and freely rotatable thereon is the drive pulley 18 retained between the collars 19 and 20 fixed to the shaft 17. In the collar 20 is a pocket 21 and an opening 22 communicates therewith. A rod 23 extends through the opening 22 into the pocket 21 and has a guide collar 24 thereon. A spring 25 is dis posed around the rod 23 between the bottom of the pocket and the guide collar 2%. At the outer end of the rod 23 and unitary therewith is a surface cam 26 having a notch 27 therein. Bearings 28 and 29 have an operating rod 30 extended therethrough on which rod a collar 31 is secured below the bearing 28. A coil spring 32 is disposed around the rod 30 between the bearing 29 and the collar 31 and normally urges the collar into engagement with the bearing 28. The pocket 21 and, therefore, the rod 23 are radially located with respect to the shaft 17 and an opening 33 in the pulley 18 is correspondingly radially located from the shaft 17. Suitable means are provided for moving the rod 30 downwardly to retract the upper end of 1 the rod from the notch 27. The spring 25 acts on the collar 2% and moves the rod to- .ward the pulley 18 and when the opening 33 moves into alinement with the rod 23 the end of the rod 23 enters the pocket 33 and interconnects the collar 20 and the pulley 18 and, therefore, the shaft 17 and the cam 26 will be rotated. As soon as the cam 26 begins to rotate the rod 30 is released and the spring 32 forces it upwardly into engagement with the periphery of the cam 26. .Vhen the end 34 of the cam 26 passes the rod 30 it moves upwardly until the collar 31 abuts the bearing 28. The upper end of the rod 30 will then lie in the path of the cam 26. Continued rotation brings the lowest point 35 of the cam 26 into engagement with the rod 30 and the inclination of the cam will, during continued rotation. cause said cam to be moved away from the collar 30 which will retract the end of the rod 23 from the opening 33 thus disconnecting the device from the pulley 18. Immediately after retraction of the rod 23 from the opening 33 the rod 30 will drop into the notch 27 and arrest further movement, this action being aided by braking devices commonly used in machines of this character. At the end of the drive shaft 17 opposite the pulley 18 is a link 37 connected to a link 38 attached by a toggle connection 39 to the upper end of the plunger 6. lVhen the main shaft 17 is rotated the plunger 6 will be reciprocated. Our protecting device is adapted to prevent move ment of the rod until the material is properly located between the top and bottom sets. A collar 40 is secured at the end of the lever 41 and has an opening therein surrounded by the flange 42. 15 is alined with the opening in the collar 40. Secured to the standard 1 is an angle bracket 43 having a hinge structure 44 thereon providing a fulcrum for the lever 41. At the end of the lever 41 opposite the collar 40 is a lever arm 45 the end of which is disposed below the collar 31. A spring 46 is connected to the lever 41 between the fulcrum and the lever arm 45 and acts on the lever to urge the collar 40 upwardly. The action of the spring 46 is limited by a suitable stop which, in the present instance, is provided by the bearing 29 against which the end of the lever rests. The material is indicated by 47 and has an opening 48 therein in which an eyelet is to be installed. The material 47 is rested on the flange 42 and pressure is applied to pivot the lever 41 downwardly. If the opening 48 is properly alined with the bottom set 15 this bottom set will enter the opening 48 and permit the lever 41 to be pivoted sufficiently to retract the arm 45 from below the collar 31, as shown in dotted lines in Fig. 3. If, however, the opening 48 and the bottom set 15 are not properly alined the engagement between the bottom set and the material 47 will prevent downward movement of the lever 41 and, therefore, the arm 45 will remain below the collar 31 to prevent downward movement thereof and, therefore, downward movement of the rod 30. It is, there fore, apparent that proper alinement of the bottom set 15 and the opening in the material to receive an eyelet must be established be fore the machine can be operated. This will prevent damage to the material by operation of the machine when the material is not properly alined with the sets.

While we have illustrated and described a selected embodiment of our invention, it is to be understood that this is capable of modification and changes in construction without departing from the purview of the following claims.
