A piston (3) for impulsively delivering mechanical energy is connected with a crank shaft (5) having a pin (5a) in co-action with a first coupling member (2a, 2b) on a rotatable member (2). The pin (5a) forms a second coupling member, which accompanies the movement of the rotatable member (2) during
A piston (3) for impulsively delivering mechanical energy is connected with a crank shaft (5) having a pin (5a) in co-action with a first coupling member (2a, 2b) on a rotatable member (2). The pin (5a) forms a second coupling member, which accompanies the movement of the rotatable member (2) during one half revolution thereof, whereupon an energy-absorbing means, for example, a spring (4) arranged around the piston (3) is compressed. When the rotatable member (2) has reached a limit position, the coupling engagement between the coupling members is instanteously broken, whereupon the energy stored in the spring or the like is transferred to the piston, which executes an impulsive percussion movement. The cycle is repeated when the coupling member (2a, 2b) of the rotatable member is again brought into engagement with the pin (5a).

A high speed punch press apparatus for briefly storing and impulsively delivering mechanical energy, comprising: (a) a circular rotatable member (2), (b) means (7) for rotatably driving the rotatable member, (c) a relatively light weight, linearly reciprocable power delivering device (3), (d) an elastically compressible energy absorbing member (4) operatively coupled to the power delivering device for compressively storing energy during movement of the power delivering device in one direction and for expansively releasing such stored energy to rapidly move said device in an opposite direction at a rate of acceleration substantially exceeding that of gravity upon the rotatable member passing a limit position, such that the resulting impulsive energy delivery rate exceeds 750 strokes per minute, (e) a first coupling member (2) defined by the rotatable member, and (f) a second coupling member (5a) connected to the power delivering device by a crank (5) and operatively disposed for engagement with the first coupling member, wherein: (1) the first coupling member comprises a closed curve within the circular rotatable member successively defining, in a direction of rotation thereof, a single, inwardly extending, tooth-like dogging projection (2a), a single adjacent, outwardly extending recess (2b) radially spaced from a center of the rotatable member, and a circular arc (2c) having a constant radius substantially equal to a radius at a greatest depth of the recess, wherein said closed curve thus approximates the shape of a central vertical section through an apple, and (2) the second coupling member comprises a follower pin configured to mate with and nestingly engage within the recess and the dogging projection for movement in a constant radius path from a lower released position to an upper, diametrically opposite position whereat the rotatable member is at its limit position such that the follower pin movement repetitively approximates that of a semi-circular path in engagement with the recess closed by a diametrical path free of any engagement with the first coupling member.
