Abstract

1345726 Hoists GARDNER-DENVER CO 27 May 1971 [18 Nov 1970] 40352/72 Divided out of 1345725 Heading B8B [Also in Division F2] The subject matter of this Specification is identical with that described in the Parent Specification 1,345,725, but the claims are concerned with the flow control means 98 which either restricts or permits unrestricted fluid flow to the hoist motor chamber, in response to the pressure prevailing in the chamber, which is representative of the load on the hoist once winding is started.
