To aZZ zoltom' it may concern: p link fit 'Beit known that I, OLIVER II. ROBERTSON, of 11 V b otForestville, in the county of Hartford and t elosethe other- 5 new and useful Improvements in Nut-Oraekconnect the link and jaw securely. The link ers, of which the following is afull, clear, and is preferably made of a single piece of metal exact description, whereby any one skilled in formed to shape, with the central portion out the art can make and use the same away, leaving a pivot g, and having at the '60 to device for cracking nuts that can be held in are all preferably made of cast metal formed the hand of the user and operated with power to the desired shape and of such proportions suflicient to crack the strongestnut that may as to be readily assembled. It is desirable be inserted between the jaws that the jaws should be normally held apart,

To this end my invention consists in the deas by means of a spring, and this is effected I5 tails of the several parts making up the nut in the form shown by means ofa spiral spring and pointed out in t 0 claims. against a shoulder or partition 7L3, formed on teferring tothe drawings, Figure 1 is a dethejaw 71, the spring being always held under 20 tail side view of the nut-cracker, showing in compression.
