Assignee:

Tol-O-Matic, Inc. - Minneapolis MN

International Classification:

F15B 1526

US Classification:

92 23

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.

US Classification:

92 88

Abstract:

A pneumatic cylinder having an elongatged cylinder member, a reciprocally movable piston, an elongated slot formed in the cylinder member, a seal for sealing the slot during reciprocal movement of the piston and a transfer means for transferring reciprocal movement of the piston to a workpiece. The above pneumatic cylinder includes a mechanisn for providing pneumatic fluid pressure to a secondary pneumatic unit connected to, and movable with, the piston including a manifold connected with the transfer means and conduit members extending from the pneumatic chambers in the cylinder member for directing pneumatic pressure from such chambers to the transfer means.
