Abstract

A format-part fastener for attaching an interchangeable format part to a machine frame includes a first connecting element having a mounting stud that extends along the stud's axis and that has an angled face that defines an acute angle relative to the stud's axis. A second connecting element has a locating sleeve for receiving the mounting stud. The locating sleeve has walls forming a slot. When used to attach a format part, a spring cotter's undulating section surrounds part of the locating sleeve's circumference while the slot supports the spring cotter's shank against the mounting stud's angled face. This converts some of the spring cotter's radial force into an axially directed force along the stud's axis.

First claim

Having described the invention, and a preferred embodiment thereof, what is claimed as new, and secured by Letters Patent is:

1. A manufacture comprising a format-part fastener to be used for attaching an interchangeable format part to a machine frame, wherein said format-part fastener comprises a first connecting element, a second connecting element, and a spring cotter, wherein said first connecting element comprises a mounting stud, wherein said mounting stud extends along a stud axis, wherein said mounting stud has an angled face that makes an acute angle relative to said stud axis, wherein said second connecting element comprises a locating sleeve for receiving said mounting stud, wherein said locating sleeve comprises walls forming a slot, wherein said machine frame is a frame of one of a container treatment machine and a container transport device, wherein said spring cotter comprises an undulating section and a shank section, wherein, when said fastener is being used for attaching a format part, said undulating section surrounds part of a circumference of said locating sleeve, and said slot supports said shank section against an angled face on said mounting stud.

2. The manufacture of claim 1 , wherein said angled face presents a profile such that a spring force exerted by said shank section radially inward toward said centerline causes said stud to exert an axially directed force that causes contact faces of said first and second connecting elements to lie against one another.

3. The manufacture of claim 1 , wherein said angled face defines an angle that opens towards a free end of said mounting stud.

4. The manufacture of claim 1 , wherein said angled face is a part of a wall that forms a circumferential groove in said stud.

5. The manufacture of claim 1 , wherein said first connecting element comprises an annular face that surrounds said mounting stud, wherein said locating sleeve comprises an annular face, wherein said annular face of said first connecting element forms a first contact face, and wherein said annular face of said locating sleeve forms a second contact face.

6. The manufacture of claim 1 , wherein at least one of said first and second connecting elements comprises a connecting plate that is attached to said format part.

7. The manufacture of claim 1 , wherein at least one of said first and second connecting elements comprises a connecting plate that is attached to said machine frame.

8. The manufacture of claim 1 , wherein said first connecting element is provided on said format part and wherein said second connecting element is provided on said machine frame.

9. The manufacture of claim 1 , wherein said second connecting element is provided on said format part and wherein said first connecting element is provided on said machine frame.

10. The manufacture of claim 1 , further comprising said interchangeable format part.

11. The manufacture of claim 10 , wherein said angled face presents a profile such that a spring force exerted by said shank section radially inward toward said centerline causes said stud to exert an axially directed force that causes contact faces of said first and second connecting elements to lie against one another.

12. The manufacture of claim 10 , wherein said angled face defines an angle that opens towards a free end of said mounting stud.

13. The manufacture of claim 10 , wherein said angled face is a part of a wall that forms a circumferential groove in said stud.

14. The manufacture of claim 10 , wherein said first connecting element comprises an annular face that surrounds said mounting stud, wherein said locating sleeve comprises an annular face, wherein said annular face of said first connecting element forms a first contact face, and wherein said annular face of said locating sleeve forms a second contact face.

15. The manufacture of claim 10 , wherein at least one of said first and second connecting elements comprises a connecting plate that is attached to said format part.

16. The manufacture of claim 10 , wherein at least one of said first and second connecting elements comprises a connecting plate that is attached to said machine frame.

17. The manufacture of claim 10 , wherein said first connecting element is provided on said format part and wherein said second connecting element is provided on said machine frame.

18. The manufacture of claim 10 , wherein said second connecting element is provided on said format part and wherein said first connecting element is provided on said machine frame.
