THE NORRIS PETERS c0 PHOTO-LITHO.. WASHING ION. By C UNITED sTAT srATENT OFFICE.
CAR-L STOEBER, OF WURZBURG, GERMANY.
EYELETING APPARATUS.
Application filed February 11, 1914.
To all whom it may concern:
Be it known that I, CARL STOEBER, a subject of the German Empire, residing at Wurzburg, in the Kingdom of Bavaria, Germany, have invented certain new and useful Improvements in Eyeleting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in eyeleting apparatus.
In the use of eyeleting apparatus. the end of the eyelet is liable to be torn at various parts when being clenched on the paper. have discovered that this objectionis avoided by slightly rotating the eyelet while being clenched.
Therefore the object of the improvements is to provide an eyeleting apparatus or machine in which the end of the eyelet can not be torn when being clenched.
With this object in view my invention consists in so constructing the apparatus, that the punch and the cooperating die for turning the end of the eyelet outward have a certain rotary movement relatively to each other while the end of the eyelet is being turned outward.
For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing which shows a side view of the apparatus partly in section.
In the example shown in the drawings the eyeleting apparatus is constructed in the form of a pair of parallel pliers. But I wish it to be understood that my invention is not limited to the construction shown in the drawings, and that it may be embodied in apparatus or machines of different con 'structions. A
As shown the pliers consist of a pair of handles 70 and 2' pivoted to each other at p and acted upon by springs Z and Z. tending to force the same apart. At their front ends the said pliers carry jaws y and 2 which are mounted on pivots s, s and 1', 1"

engaging rear extensions n and 0 of the jaws. At its front end the jaw y is formed with a bore having internal screw-threads of large pitch, and the said bore receives the shaft 6 of a punch a, which shaft is formed with external screw-threads corresponding to those of the bore 00. At its rear end the shaft (2 is formed with a rounded head 0 which is engaged at its inner face by a coiled spring 10 bearing with its opposite end on the face of the jaw y, and at its outer end it is engaged by the end of a rocking lever 03 which has a rocking support on the jaw y at t. The arm is provided with a rear extension 1:- which is adapted to be engaged when closing the pliers by a pin m secured to the arm 0 of the jaw z.
The die cooperating with the punch a is secured in a bore made in the jaw z, and it is constructed in the form of a sleeve 6 receiving a longitudinally slidable pin 9 and having at its inner end a socket for turning the end of the eyelet outward. Around the said pin a spring 7 is coiled which bears with one end on a plug 6 secured to the sleeve e and with its opposite end. on a collar it formed on the pin 9. The spring has the tendency to force the pin 9 outward.
In the operation of the apparatus an eyelet is placed on the pointed front end of the punch a, whereupon the pliers are closed so as to force the jaws toward the paper. When the punch and the pin gget in contact with the paper the latter is punched, while the punch is being depressed by the rocking lever 01 which is engaged at its rear end it by the pin m. Simultaneously rotary movement is imparted to the punch which prevents tearing of the end of the eyelet while being forced through the paper and turned outward. After the eyelet has been set, the handles are forced outward by the springs Z and Z, and the punch a is retracted by the spring to, and the pin 9 is forced forward by its spring 7.
I claim herein as my invention:
In an eyeleting apparatus of the character described, the combination with a punch and a punching and eyeleting die 'cofiperat- In testimony whereof I'hereunto afiix my mg therewlth of means for forcing said signature in the presence of two Witnesses. punch and die toward each other for vertical engagement between an eyelet and said I CARL S 5 punch, and means for simultaneously im- Witnesses: I
