Abstract
A pneumatic cylinder having an elongated cylinder member, a reciprocally movable piston, transfer means for transferring reciprocal movement of the piston to a work piece and a brake mechanism associated and movable with the transfer means for creating a braking force between the transfer means and a portion of the cylinder member. The brake mechanism includes a first brake surface connected with the transfer means, a second brake surface formed by an exterior surface portion of the cylinder member and a brake actuation mechanism for selectively causing movement of the first and second brake surfaces into braking engagement with one another.
Claims19
A pneumatic cylinder comprising:
- an elongated cylinder member having an elongated bore extending therethrough;
- a piston disposed within said bore and adapted for reciprocal movement therein;
- transfer means connected with said piston for transferring reciprocal movement of said piston to a workpiece including a carrier bracket having a combination guide and brake means for selectively guiding the reciprocal movement of said carrier bracket relative to said cylinder member and braking said carrier bracket relative to said cylinder member, said combination guide and brake means including a pair of spaced leg portions extending outwardly from a central portion wherein each of said leg portions includes an elongated bearing member, said bearing member cooperating with a corresponding bearing surface on an exterior surface portion of said cylinder member to selectively guide the reciprocal movement of said carrier bracket relative to said cylinder member, said combination guide and brake means further including
- a first brake surface formed by a portion of each of said bearing members, a second brake surface formed by a portion of each of said corresponding bearing surfaces and brake actuation means for selectively causing movement of said first and second brake surfaces into braking engagement with one another to selectively brake said carrier bracket relative to said cylinder member.
