Abstract
Three steel probes such as 30, Fig. 1, may be fired into concrete 32 through three upstanding bosses 33, Fig. 3, in a hardened steel template 31. The housing 10 must be telescoped downwardly over the boss it is engaged with in order that the barrel 11 may be depressed sufficiently to slide a breech block 12 and a cocking rod 19 upwardly, and when this is done the rod engages a depressible pawl 18 extending outwardly from a firing pin 15 and moves the pin back against a spring 16 to the Fig. 1 ready for firing position. A trigger 20 pivoted at 21 may be pulled to push the pawl 18 inwardly and release the firing pin which explodes the powder in the cartridge 22 and fires the probe 30. The opening 34 through which the probe nose passes will not allow the enlarged rear end of the probe to pass through so that the probe cannot go into free flight if the material 32 is very soft.
