If the following advance impulse is also to be absent, the movable organ is activated again by the Prcujrammnocken returned to its first position. If in contrast to do this, the following Vp rrjick pulse cannot be suppressed or should not occur, the movable organ is held in its third position.

In a modified embodiment of the invention forms the movable member, which can take up three positions, at the same time the locking member for the time wheel, whereby it is possible to omit the above-mentioned pawl.

This embodiment of the device according to the invention is characterized in that the movable organ has a nose or a ^{pinger 7} ,, which interacts with a toothing of the time wheel in order to counteract a reset movement of the time wheel into the Hull or starting position, both , when the movable member is either in the first position, in which the step-by-step advancement does not take place with the tactile finger resting on a region with a small diameter of the ProkTammnockens, or in the second position, which is formed by a ^r :! eil de3 Zeitrad.es is controlled, and in which a step-by-step advance takes place in one step, while if an advance takes place by one step and the sensing finger passes over to an area of larger diameter of the program cam E, the movable member is guided into its third position and the The rabbit or the pinger stops, to interact with the toothing of the time wheel, which returns to the UuIl or starting position under the action of its return spring.

Further details and features of the invention result from the following description of three embodiments of the invention disclosed in a scholarly manner in the enclosed Zeicxmünc 'is shown, in which, for the sake of clarity, not all organs of a known project

gram generator are reproduced, but only the elements necessary to understand the invention. Show it

Pig. 2 shows a view, analogous to the representation of FIG. 1, of a first embodiment of the invention, and FIG

Pig. 3 one of the pig. 1 analogous representation of a second modification of the invention.

For a better understanding · of the subject matter of the invention I will briefly look ahead to the operation of the elements of a known programmer (see patent application P 15 88 119.3 of December 15, 1967).

In Pig. 1, 1 denotes the axis of the cam discs; with 2 the reversing or switching cam is referred to, which moves continuously in the direction of arrow 2a; at 3 is a fixed structural element centered on the supports of the assembly, one of which supports P is shown; 3a with a continuous cylindrical surface or track is designated, which forms the track of an inner cam and has an interruption or notch 3e; 4 denotes a transmission lever which is mounted ver.'jchv / enkbar on an axis 2b, which is fixed on the U'msteuerungsnockenscheibe 2 and with a button nose 4a, which is intended to the profile or the raceway 3a to.follow, "and egg arn 4'b is provided ^: t to actuate the approach 5a of a coupling ₍ ; öbe.ci & Muigweise ücii.

a bevel 5b is provided and pivots on the axis 2c is stored, which is attached to the reversing dry disk is; with 6 the uockenag ^ regi-.t is designated, its front side v; eg: is cut to show the internal toothing 6a and the progression or selection notices in the drawing 6b show ku more clearly; 7 is a movable pivotable one Organ, v / elches one. Sensing finger 7a, the one with the program cam 6b collapses, and a profile surface 7b r, ufv / eist, which closes the I erbe 3b in the position shown and ensures the continuity of a career 3a.

The entire program generator part containing elements i to 7 is known, and its simple operation is-how follows:

When the movable member 7 is in the position shown in the drawing, that is, when a sensing finger 7a is on part of the programming cam 6b. If, in contrast, the sensing finger 7a is moved outwards, it moves on part of the program cam 6b with a large Pfedius, then the profile surface 7b no longer ensures the continuity of the cylindrical raceway 3a, so that when the iÜKSternase 4a passes the notch 3b, the lever 4a makes the pawl 5b FiOgIiCh, under the action of a ( not shown) spring to 'pivot, ". and" the pawl, whose - with' üer toothing 6a cooperating ho.se fib the temporary coupling between the Umsteuerungsnoefcenucheibe 2 and the Ifockenai-gre-

Another notch similar to notch 3b, otherwise the cam unit 6 would ultimately remain immobile.

The applicant has already thought of using the continuous rotation of the Uinsteuerungsnockenscheibe as a time base to be used to determine the amount of time that the cams of a programmer will remain motionless (see German patent application P 15 88 104.6 of July 21 1967). '

In this operating mode, a movable flap moves aeitproportionately by an angle, creating a step-shaped Pulse is generated and the flap is reset to Hull. -

According to a modified embodiment (see German Patent application P 18 04 916.6 of October 24, 1968) a timer intermittently "angularly displaced" by a driver finger by an angle equal to that of the Time is proportional, creating a stepped pulse is generated and the timer is reset to iiull will.

Bank of the arrangement according to the invention, it is in particular possible to adjust the size of the square depending on the Vhmseh, around the df; s time number rlied revolves, that is, it is possible to set the time from the year of the step-shaped Pulses are interrupted.

The inventive arrangement contains a time wheel 8 which is provided with a contact 8a, -> r. to which a linden tree of a return spring 9 is attached, which is partly led around aie table 8b of the wheel 8, while the other linden tree is the pe- ^; which is attached to a point 1f of the i-'rograringeber _s ; ehsuses' ί

A pawl 11, which consists of an elastic lamella, acts under the action of the return spring 9 of the Backward movement of the wheel 8 against. The axis 12 of a rotatable part, which with respect to the rotary drive with the Umsteuerurigsnockenscheibe is connected, has a Mitnehiaerfinger 12a, which cooperates with the external toothing 8c of the wheel 8, around the wheel 8 at.each revolution by one tooth to continue rotating, in the opposite direction to the direction of force P of the elastic return spring 9.

On the wheel 8, a stop 8d is arranged, which against a on a dial 13 arranged stop 13a comes to rest when (after the pawl 11 has been lifted is) the wheel 8 has returned to its original position under the action of the return spring 9. A gear transmission 14, 14 *, which the adjusting wheel 13 with an adjusting knob 15 connects, enables .es to set the starting point of the wheel 8 or to regulate.

The movable ürgan 7 contains an arm 7c y which lies in the plane swept by the stop 8d. In a first, illustrated in the drawing position in which the profiled surface 7b the notch 3b closes or covers, the end protrudes of the Army 7c in the prescribed by the stopper 8d loading ^(orbit, so that the in the rotation of the wheel 8 Stop 8d acts on arm 7c in order to move the.-Frofilflache 7b into a second position in which, with the notch Tb * exposed, a gradual backward movement or further movement will take place when the iasternase 4a is in front of the notch '$ h .

While rotating or advancing one Step leads a rc with the sensing finger 7a cooperating

Projection of the program cam 6b moves the movable member 7 into a third position. In this third position one lifts Another arm 7d, which was not in contact with the pawl 11 in the first two positions, this pawl on, whereby the toothing 8c is released and under the Effect of the return spring 9, the return movement of the time wheel 9 is made possible in the starting position.

When the following red. 'Tion postponed by one step v / should be grounded, the head start of program mocking has one small angular extension, and after the rotation the movable member is under the action of a return spring 16 returned to the first position. If, on the other hand, the following step should not be postponed, if the protrusion has an angular spread ·:,. which is greater than a '.step, and the movable organ is in the third Position held.

A spring 17 gc '^ you provide the exact five-way position of the R of the 1'j, so that the. first impulse respectively Step .des finger 12a can take place without jamming.

In the variant shown in FIG. 2, in which the same reference lines have been used to designate the same elements described above, the wheel 8 has the shape of a hollow cylindrical bush, v / o at the open or hollow side rests against a plate 18 »The lateral inner surface of the Tiohl cylinder has a stop 3d which, when the ud 8 has been returned to the gauze or starting position by the return spring 9, £ ■: e .mi the stop 1,5c, which is non-rotatably connected to the I.Ins part wheel Π, which is arranged behind the plate 18 and via the ^ annrL'der 14, 14 ¹ with an adjusting knob
