IBY DIRECT AND MESNE ASSIGNMENTS, OF TWO-THIRDS TO BRANT.AND ONE I THIRD TO LEE IB. DUNCAN, OF ACOSTA, VIPEBENSYLVANIA ,NUT-sI- nmineroon f Application filed January aaf-ieaa; Serial-1T0. 335,767.

The present invention relates to improve ments in the artof tools, and more particular, the invention has reference to a novel cutting tool especially adapted for, splltting' nuts. a

A tool of this character is verypractic al-in use insalvaging old coal cars and various other structures, whereon the nuts havefbecome firmly corrodedor otherwise bindedto the bolts, so that it is necessary that the nuts,

be actually broken in order to removethe 7 bolts. 7

- vide a cutting tool including a' chisel ele-,- 2 0 fhe paramount object is to provide a tool ofthis character capable of exerting a powerful pressure against a nut in order to quickly and safely split the nut so that the same may be displaced from the bolt.

Another object of importance, isto proment removably associated with the tool.

Still'another object is to provide a tool wherein cutting elements of varying lengths tudinal sectional view of the jaws disengaged v tional view showing the .jaws engaged with:

from the cutting element, and furthershowing the cutting element 1n retracted position.

Fig. 3 is a fragmentary longitudinal secthe cutting elements, and showinggtheelements'partially moved toward a nut to be split. l

Fig. 4' is an one of the cutting elements.

Fig. 5 s an enlarged fragmentary perspective view of one ofthe jaw members.

' Fig. 6 represents a fragmentary perspece tive view of an extension handle for the tool.

' Referring to the drawings. wherein like I numerals designate like parts, a head generally referred to by the numeral 1, includes" a yoke 2 having an angular shaped protubere employed for cutting nuts of dif-' 'tures 16 ',16.{,. I Y 1 z iljhe jaws 111*:Q1"1 :areeach-provided with a' protubei'ancelii, for engagement ":within J i one of the indentures 16, whilefeac-h jaw is enlarged perspective I view. of

since-3, at the inner edge of'its portion.

QThe end portion of its legs are widened at- 4 to provide :a 'relatively narrow slideway 5, for the .cuttingabit ,6. 1 The. opposite-sides of the portions4- ofjthe yoke are covered by plates-7, which are securedtothe yokes by.

suitable rivets 8. The rearward endof each plate 7 ,is provided-with ,aipair of'fspaced ears; 9-,9. V r V J Bolts 10 are disposed through the c'orres sponding ears ofthe plates 7*for pivotally connecting a pair of: jaws I1. 1l t0 the-head. and between-the plates 7. and -a"Y-'shaped guide member 12 by the extremity; of its legs to oneoftheht 7 .1Ni 1 r papiplled t tS'fOrsecuI'i gtheSG Parts p perorder. V

The cutting bit 6'is'elongate'd and pasted at one end, while its opposite end is slightly Y flared a-s-v denoted bythe numeral .14, and .70

provided with a ourved face l5." Adjacent the flared end of the bit, opposite longitudi nal edges of the bit are formed "with inden further provided with a shoulder 18 having a curved space-19.1 Thepivot 'point'of each jaw .is in eccentric relation to theaXis of the so Q,

curved face l9,-so'that when the, shoulder.

18 is movedtoward the bit 6, the curved face 19 will exert acam action againstthe "curved face 15, of thezbit, resulting in a rectilinear ofthe head." TIC 7- 'EajchjawII i'sgprovidedlwith a shank 6X tension 20, bifurcated at its outer endf21. A pair of bars 2222 are pivotally mounted at their intermediate portions within the bi furcated ends-of the shank 20, while one end i I of each ispivotally: connected to the other, by means of an element 23 capable of slidable disposition"within the slot 24, of the' guide member, 12. I 1 1 To aflord a greater leverage for the jaws 1111, an extension unit generally referred to by the numeral 25, is provided for each" ,bar. 22. Eachextension unit consists'of a let;

3O 7 i A tool of thecharacter:descr bedv comprising a yoke shaped head, plates secured handle barf 26, provided adjacent one end with a pair of spaced boxes 2727.

Iii

The boxes are open at their respective ends, so that the bar 22 may Joe disposed 'ther'ethrough and secured by means 28.

It is preferable that the forward end portion o'fthe yoke 2 be disposed obliquely so that the tool may be held away from the a struCiure uponwhich the work is being con-I ducted. i

By properly disposing the yoke 52 overa' V nut to besplit, and against the pointed protuberance 3, the bars 22 may be contrasted f v 7 so as to cause the swinging of the jaws f Y l1 -11. F As the shank 20. of thejaws move inwardly, the protuberances 17 on the jaws a engaging in the indentures 16 of the bit 6,

wzillwcause the =feedingof the bit 6 toward the nut and if desired,-Pagainst'the nut.

Subsequently, the shoulders 18 will en'- gage the curved face of the bit 6 and through the cam'action aforementioned, will exert a powerful rectilinear pressure against the bit 6', to split the nut. Certain specific-changes in the shape, size, and materials may be resorted to. inthe construction-of this device" without departing from the spirit and scope Ofithe invention as claimed hereinafter.

' aving thusdescribe'dour invention, what We olaim'as new is:$

to opposite sides of the legportionsf ofthe head, each plate being providedat one end with a pair ofsp'aced-ears, a Y-sha-ped guide I member, the legs of the guide member'be-J ingseoured to the ears of one plate,said Y- shaped member being provided with a 10-11- gitudinal slot, a pairno-f jaws pivoted be- 4 tween said plates, said jaws bein'gleach provided lwith a shank, a pair. of 1'evers,aneleo ment for pivotallyconnecting:the levers to- 'gether atone end, said element being engaged throughthe slot of the guide member, the outer ends of theshanks being pivotally connected to said levers, a tool eleme'nt slid ably disposed within the head, and complek ment-arty means between the jaws and said tool whereby the tool may be urged against a nut'disposed within the head;
