Abstract
Abstract Device for removably mounting a hollow friction cylinder in inking and moistening apparatus of a printing machine includes clamping means comprising a clamping screw and nut threaded thereon located within the friction cylinder, respectively at opposite ends thereof, and being mutually threadingly rotatable for varying the length of the clamping means, bearing pins for the friction cylinder having a receiving shell wherein respective end portions of the screw and nut are received form lockingly in axial direction and removably in radial direction thereof, each bearing pin having a flange substantially conforming to a guide bore formed in the friction cylinder, the clamping means being actuable externally to the friction cylinder to force the flanges into the respective guide bores.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
224 words
Device for removably mounting a friction cylinder in inking and moistening apparatus of a printing machine comprising clamping means disposed within the friction cylinder and coaxial thereto, said clamping means including a clamping screw and a clamping nut extending into the friction cylinder from opposite ends thereof, said clamping nut being threaded on said screw, said screw and nut being threadedly rotatable relative to one another so as to vary the length of said clamping means, a bearing pin located at each end of the friction cylinder and adapted to be axially displaceably received at an outer end thereof in a respective bearing bushing mounted in a sidewall of the printing machine, said bearing pins having a receiving shell at the inner ends thereof for receiving therein an end portion of said clamping screw and said clamping nut, respectively, said clamping means being thereby suspended in said receiving shells of said bearing pins, the respective end portions of said screw and said nut being form-lockingly secured in said receiving shells in axial direction thereof and being removable therefrom in radial direction thereof, each of said bearing pins having a clamping flange conforming substantially to a guide bore formed in the friction cylinder, said clamping means being actuable from the outside of the friction cylinder to force said clamping flanges into the respective guide bores.
Claim 2
Dependent Claim
224 words
Device for removably mounting a friction cylinder in inking and moistening apparatus of a printing machine comprising clamping means disposed within the friction cylinder and coaxial thereto, said clamping means including a clamping screw and a clamping nut extending into the friction cylinder from opposite ends thereof, said clamping nut being threaded on said screw, said screw and nut being threadedly rotatable relative to one another so as to vary the length of said clamping means, a bearing pin located at each end of the friction cylinder and adapted to be axially displaceably received at an outer end thereof in a respective bearing bushing mounted in a sidewall of the printing machine, said bearing pins having a receiving shell at the inner ends thereof for receiving therein an end portion of said clamping screw and said clamping nut, respectively, said clamping means being thereby suspended in said receiving shells of said bearing pins, the respective end portions of said screw and said nut being form-lockingly secured in said receiving shells in axial direction thereof and being removable therefrom in radial direction thereof, each of said bearing pins having a clamping flange conforming substantially to a guide bore formed in the friction cylinder, said clamping means being actuable from the outside of the friction cylinder to force said clamping flanges into the respective guide bores.
Claim 3
Dependent Claim
55 words
Device according to claim 1, wherein one of said two bearing pins is formed with a longitudinal bore for receiving a key therein, said key having a flattened head similar to that of a screwdriver, said flattened head being insertable in a matching slot formed in one of the end portions of said clamping means.
Claim 4
Dependent Claim
21 words
Device according to claim 2 wherein the end portion formed with the slot is the end portion of said clamping screw.
Claim 5
Dependent Claim
178 words
Device according to claim 3 comprising a safety device including a locking pin slidable between a locking and a disengaged position in a blind bore formed in said clamping screw and extending coaxial therewith, a helical spring disposed in said blind bore and continually biasing said locking pin in direction toward said slotted end portion of said clamping screw, a pair of ball members located diametrically opposite one another in a bore formed in said clamping screw transversely to the axis thereof, said ball members, in said locking position of said locking pin, being pressed against a shoulder of a bearing bore formed in the friction cylinder, said locking pin being slidable against the force of said spring in said blind bore in response to a force applicable through said key head received in said matching slot formed in said clamping pin so that an annular groove formed in said locking pin is radially aligned with said ball members whereby said ball members are freed from said shoulder of said bearing bore and drop into said annular groove.
Claim 6
Dependent Claim
156 words
Device for removably mounting a hollow friction cylinder in inking and moistening apparatus of a printing machine comprising clamping means including a clamping screw and a clamping nut threaded thereon extending into the friction cylinder, respectively, from opposite ends of the cylinder, and being mutually threadedly rotatable for varying the length of said clamping means, axially displaceable bearing pins for the friction cylinder having respective receiving shells wherein respective end portions of said screw and said nut are received, means for form locking the respective end portions in said receiving shells against relative displacement in axial direction thereof, and means for affording removal of the respective end portions from the receiving shells in radial direction of the respective end portions, each bearing pin having a flange substantially conforming to a guide bore formed in the friction cylinder, said clamping means being actuable Externally to the friction cylinder to force said flanges into said respective guide bores.
