Theapparatus 10 may also include aguard assembly 22 coupled to thecylindrical body 12. In the illustrated embodiment, the batteringram release mechanism 20 takes the form of amanifold 24 including a valve. When thetriggering mechanism 28 is activated, air flows through themanifold 24 from thereservoir tank 62 to theair chamber 66. The pressure of the air entering theair chamber 66 causes thepiston 32 to move forward to its extended position, this releasing thebattering element 14. - In the illustrated embodiment, the
battering element 14 takes the form of a batteringhead 34 attached to ashaft 36. As shown inFIGS. 3A to 3E , the batteringhead 34 is preferably located within theguard 22 when the head is in its retracted position (FIG. 3A ). When the batteringhead 34 is in its extended position, it extends at least partially out of the guard 22 (FIG. 3C ). - In the illustrated embodiment, the battering
ram return mechanism 18 takes the form of aspring 38. Thespring 38 is preferably disposed between thebumper 40 and thepiston 32.

Thespring 38 then returns to its normally extended position, pushing thepiston 32 to its retracted position. - In the illustrated embodiment, as shown in
FIGS. 3 a to 3E, theair release mechanism 16 takes the form of apiston 32 coupled to theshaft 36. As shown inFIG. 4 , thepiston 32 includes a plurality ofvalves 42 to release air from theair chamber 66. The illustrated embodiment includes fourvalves 42, however, any number ofvalves 42 may be desirable depending on the particular configuration of theapparatus 10. Thepiston 32 may also include a sealingapparatus 10, such as acup seal 44 to provide a tight seal within theair chamber 66. The piston may also include at least onewear band 46, such as aTeflon wear band 46 to reduce friction.

In this configuration thevalves 42 in thepiston 32 are in the closed position. When thepiston 32 is in its extended position, thefront surface 56 of thevalves 42 engage thebumper 40 and thevalves 42 are pushed within thepiston 32 such that thefront surface 56 of thevalves 42 are flush with thefront surface 58 of the piston 32 (seeFIG. 3C ). In this manner, air can flow through the valves 42 (seeFIG. 3D ). In this configuration thevalves 42 in thepiston 32 are in their open position and air in thechamber 66 may be released throughholes 48 and achannel 50 formed in thevalves 42 and ultimately through holes formed in thechamber 66. As thepiston 32 is returned to its retracted position, therear surfaces 52 of thevalves 42 engage the back wall of theair chamber 66 and push thevalves 42 within thepiston 32 such that therear surfaces 52 of thevalves 42 are once again flush with therear surface 54 of the piston 32 (seeFIG. 3E ). - The
apparatus 10 preferably includes at least one air supply attached to thebody 12 of theapparatus 10, as shown inFIGS. 1A and 5 .

In the illustrated embodiment, when thesensing bar 70 is in its retracted position the triggeringmechanism 28 is activated. In use, thesensing bar 70 is moved from its first position to the second position by swinging thesensing bar 70 into a door or other item to be rammed. - In the preferred embodiment the triggering
mechanism 28 comprises apeg 72 which may be depressed by thesensing bar 70 when thesensing bar 70 is in its second retracted position. Depressing thepeg 72 opens avalve 26 within themanifold 24. - The

However, it should be understood that the location and configuration of thehandles 84 may be changed. - It is contemplated that
different head 34 configurations may be best suited for different applications. For example, theoptimum head 34 configuration may be different for breaking bricks, metal, or wood. Therefore it is contemplatedalternate head 34 designs may be utilized. It is further contemplated that theapparatus 10 may includeinterchangeable heads 34 which may be removed and replaced to accommodate various conditions. - It is also contemplated that any type of air tank may be used. For example, SCBA (self contained breathing apparatus) tanks which are often used by firefighters may be attached to the
apparatus 10. It is also contemplated that smaller emergency bottles, such as Ska-Pak bottles may be used. Such tanks may be connected S to the manifold in any manner known in the art, for example with a whip hose and quick connects. Many firehouses have the means to refill such tanks, therefore this type of tank would be easy to refill and maintain. -

Engagement of therear surface 54 of thepiston 32 with the rear wall 30 of thechamber 66 moves thevalves 42 within thepiston 32 such that therear surfaces 52 of thevalves 42 are flush with therear surface 54 of thepiston 32, this moving thevalves 42 to the closed position. Theapparatus 10 is now ready to be used again. -
FIGS. 6 through 8 show an alternative embodiment of anapparatus 110 including anintegrated reservoir 162. The embodiment ofFIGS. 6 through 8 is similar to that described above, however, rather than utilizing an external reservoir tank orbottle 62, theapparatus 110 utilizes anintegrated reservoir 162 and has a manifold 124 with a different configuration. In use, the air travels from an external air supply tank (not shown) such as a SCBA bottle, through anair inlet 163 in the manifold 124 to theintegrated reservoir 162. Referring toFIG. 7 , in the illustrated embodiment air passes through thecheck valve 186 and into the reservoir. In the illustrated embodiment, air also fills thespring cavity 188 of thevalve popper 190, seating thevalve poppet 190 against thevalve seat 192. Thevalve seat 192 may include a sealing means such as an o-ring. - The operation of the
apparatus 110 illustrated inFIGS. 6 through 8 is generally the same as the embodiment described above and shown inFIGS. 3A through 3E . Upon activation of the triggeringmechanism 172, the air travels from the reservoir through the manifold and into theair chamber 166. In the illustrated embodiment, activation of the plunger vents thespring cavity 188 to atmosphere. The air in thereservoir 162 overcomes the force of themain spring 194 and lifts themain valve poppet 190 off the seat allowing theair chamber 166 to be filled. Air enters thechamber 166 through anair inlet 196 which is in fluid communication with thereservoir 162. The air entering theair chamber 166 will push the piston (not shown) into its extended position as described above with respect to the embodiment ofFIGS. 3A through 3E . - The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
