Abstract
Abstract An arrangement for mounting and dismounting pivoted levers in tool housings in which the lever has a projection engaging a first groove in the tool housing and a blind bore extending transversely through the lever and coaxially within the projection, wherein an axle journal is inserted in the blind bore to project in a second groove within the tool housing. When mounting or dismounting the arrangement, an implement is introduced in a slit above the axle journal, to disengage the axle journal from the groove, thereby releasing the support of the lever.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
193 words
An arrangement for mounting and dismounting pivoted lever assemblies in tool housings, comprising a lever having two opposite lateral sides and including a projection integrally formed therewith and extending transversely therefrom, a tool housing having a recess to receive said lever and formed with two oppositely positioned elongated grooves each facing the respective opposite side of said lever, said projection being formed with an elongated blind bore having a closed end formed by said projection and extending into one of said grooves and an open end diametrically opposite to said closed end; an axle journal inserted into said open end and projecting therefrom into a second of said elongated grooves, said axle journal being adapted to move within said blind bore between a first position engaging said second groove and a second position being disengaged from said second groove; a spring mounted within said blind bore and having one end supported in said closed end of said blind bore and another end abutting said axle journal; and a sheet metal holder secured to the tool housing above said second groove for preventing an upward movement of said axle journal in said first position.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
27 words
The arrangement of claim 2, wherein said sheet metal holder includes a projection extending into said second groove for retaining said axle journal in said second groove.
