The programme drum is stationary until a tooth gap (5) is reached when the programme drum is moved forward by one tooth, provided that there is also a coincident gap (13) in the timing ring to allow the pawl to drop into the control drum gap (5). The teeth of the timing ring (12) are arranged with an appropriate stagger to give the required delay between occassions when the gaps (5, 13) coincide and the program drum is moved. USE/ADVANTAGE - The addition of a timing ring is a simple device to extend the base step timing by any desired multiple.

Inventor: KURZ FRED HELMUT
IPC: A41B1/00
Filed: 1993-02-09
Abstract: The pockets on the shirt are, as is known, attached such that they are directly accessible from the outside and are therefore not secure against pickpocketing and not suitable for keeping money and important documents in. The invention makes it possible to be able to carry along money and/or important documents such as an identity card, passport, plane ticket, credit card etc. in one or more pockets of the shirt accommodated securely against pickpocketing, in particular when out and about or on journeys. The invention renders superfluous a purse/wallet worn around the neck, which is otherwise required on journeys. This object is achieved by virtue of the fact that one or more pockets are attached to the shirt in a manner such that they are only accessible from the inside, or by virtue of the fact that in addition to pockets with access from the outside, one or more pockets are attached to the shirt in a manner such that they are only accessible from the inside. The drawing shows, as an exemplary embodiment, a shirt to which the outer pocket 1 is attached in a manner such that it is only accessible from the outside through a button fastening, and the inner pockets 2 and 3 are attached in a manner such that they are only accessible from the inside through a zip fastening. <IMAGE>
