JOHN J. KERRIGAN, or PHILADELLPHA, PENNSYLVANIA.

BOILER-TUBE CBIMPER.

o callwliomit may concern:

lie 'it known that I, 'JOHN J. KERRIGAN, e citizen of the United States, residing :it Philadelphie, vin the county ot Philadelphia .3 und Stte or' Pennsylvanirghave invented certain nevi and useful'improvements in loilerTube Criinpers, oi' which the following; is specification.

luy f "invention relates to improvements in lo boiler tube ciiimpers and has for en object to, provide e device this chnracterjvhich will crimp tlie ends of'boiler tubes and fxllowv the sume to'be removed from the heador the head from the tubes, Without destroying Eeretofore when a. tribe or vheed 'became defective or for some other reason -it was desii-ed to remove the seme from the boiler, it ,nies inecessary to cut the tubelongitudi-t 3o nn'lly and'then bend'the ends of the tube inwardly, J@hereby destroying the tube. `With mylhvent-ionl provide e lever which slm'ply b'endfs'the ends of the tube inwardly Without having-to cut. Vthe salme,4 thus allowing the A. further Objectis gto provide a device of this character which'is simple end cheep to' manuf-.ic'tnrmyet willeiciently do the Work for which itis'intended.'

.*With these and other objects in view, the? -invention consists in certain novel features of construction und combinations und .er`l rengementsof parts, as lWill be more fully hereinafter described and pointed out in the Clarins.

' gle piece of metal and comprises n handle 1 und an enlarged heed 2,. The head 2 has a curved groove therewith which the tube 8 is positioned and divides the head into en; outer and 'an inner MW. The inner Jaw 4.

is longer than the outer jew 5 and Ais beveed from i'ts'end to e point directly below the end of the outer jew 5, forming a fulcrum 6. rlhis insures the end of the tube being bent uniformly throughout its circumference and compels the metal of the tube 'between the outer jaw and the inner jeyv to'bend et the fulcrum point 6. The edges ofi-he head 2 ere beveled inwardly from their outer to their inner edges es shoWneol', thereby making the 'jew 5 of:

greater Width than the jaw 4. In operation, thetube is irstheated and then my improved device is placed thereon ywith the ,end of the tube inserted in. the,` groove between the jaws 4 rand 5 as shown Fig.' 1.-: The handle l is then moved uponl .the fulcrum 6 'and this movementvvl'licause the tubetobend at' a. point* Wberefthefend' .of jewefcolries in Contact with thevill ofl 'the tribe. @Alfter the tubehasbeen Vcrim ed at 'one point, the device is movedf farterN `veroun'dzon the tube and the operetibnreparted,... When the entire cireum*fereiice.ofv -thet-ube hes'been so treated, itivilihavethe .appearance shown in Fig. 4, andthe tube mey easily vbe removed from'jtheboiler. When ellof 'the tubes are thus crimped', the heafdmay'be removed. i

fthe generel' form anderrangement of. parts described Wit-houtdepaiting from my invention, and hence I do not limit my selfto the 'precise details set forth, but considermvself at liberty to make such changes and alteraltionses fairly fall Within the spirit and? scope of the appended claims.

Having thus described my invention, what I clim es new and desire to secure by Let.- ters Ptent'i's: y

1. l device of the character described,

comprising@ handle, and a heed thereon,l saidhead having a curved groove therein,

dividing the said head into an inner and an outer jaw, said inner jaw longer than the outer jaw and beveled from its end une4 point directly below Whe end' of the vouterj'ew, substantially as described. l 2. A device of `the character described,

yVariousslight changes might be made in fo1:,...|f-ir,g parallel Lube gripping xed jaws name to this specifi-:ation in the presence of curved transversely, the uwer Jaw onger two subscmbmg wltnesses.
