ner end of the handle', this endheing designed as an anvil 12, against,y which the.

work rests. Theha-ndle 5 is also formed with a central bore or passage 13, opening through opposite ends thereof, so that on extracting rivets from the work by the punch 11, the same will pass through the bore or passage 13 from the handle.

Provided in one side of the head 8 is a slot 14, opening into its bore, and in which works an intu'rned nib l5, on the outer end of a flat lea-f spring 16, the opposite end of which is secured' to the handle, and this spring is designed to force inwardly the nib '15 against the punch 11 to hold the saine against a rivet, when the punch is to be struck a blow by a hammer or the like, dur-v ingv the extract-ino operation.
