The portionf24fof the wire is thus looped or guided forrunningf. connection with the guide 25 and is adapted to be drawn upon by the spring 26, the parts 25 and 26 serving as anautomatictakefup device for taking up anyv slack in the wire 22 which may occur after the wirefis' applied and the current turned `on, l such slack A commonly occurring asa result of the expansion of the wire.

'The en 23 of the wire being connected with the conductor 15A, which 1s connected with the feed Wire `7, it will be evident' that when the contact point 31 of the circuit closing device 28 is brought -into 4contaot'with the end 24 of the wire 22,"and the'switch 29 is turned on, an electric circuitwill\be-"cDmpleted entirely through the wire22, whereby said wire will be'heated throughout.- In such operationit will be apparent that' the entire circumference of the l'cylinderygat the point where it is encompassed by the jwire 22, will ybewheated for Vthe cracking Joperation.
