6- Claims. 1.

The present invention relates to an apparatuscomposed of anumber of wheels and/or movable discs; which on movingactuate a movable part comprised inthe apparatus; thus setting thispart in motion. Said motion can be used, for instance to close a circuit at predetermined times, in order to give a signal for switching on light, starting a motor or the like. It can also be arranged for actuating,.electrically or mechanically, other apparatus, thus regulating said apparatus, e. g; for starting said second apparatus, changing its motion direction, registering a certain condition in the apparatus a. s. 0.

Such an apparatus can for instance be a time registering device, the function of which is such, as will cause a regulation at certain predetermined times in order to mark different periods, a. s. 0., in different ways. In this connection, the apparatus can. be arranged so that the regulation can take place atv different times for different days. If for instance the apparatus is used for time signallingin a factory, where the workingtime is difierenton Saturdays than on the Other days of the week; the apparatus can be set so that the signals are adjusted to the times determined for each day.

The accompanying drawings show an embodiment of anapparatus conceived according to the invention, said embodiment being fit for use in connection with time control, time signalling, etc.

Fig. l is a side view of the apparatus and Fig. 2' shows a front view of the same. Figs. 3, 4 and 5 show details of the apparatus for a more clear understanding of its working system,

The frame of the apparatus consists of a pair of plates i and 2, 1, bound together by means of a pair of bolts 3 and d. A shaft 5 is fastened on said frame, the shaft, furthermqresupporting a cylinder 6, which can turn. round said shaft, said cylinder consisting of a number of discs I separated by washers; 3. The discs 1 and washers 8 are kept together by means of rivets 9 and a centre tube iii, being the layer of the cylinder 6.

The discs 7 are at their periphery provided with grooves H, into which pins 12 can be inserted. The pin it ought to be cleft at one of its ends. Hereby, there arises a certain resiliency, which serves to retain the pin on insertin it. H 0 its groove ii in the disc I. The other end of the pin 52 is provided with a head wh ch. on thehin being inserted into the groove II in the d sc 1, lies outside the periphery of said disc, a protuberance thus, being formed on the periphery of the disc. In order to drive the cylinder 6 round its shaft 5-, said cylinder 6 is provided with a toothed wheel 13, which meshes with a pinion I4, which is driven in a suitable manner from another pparatus for timesignalling, conveniently a clock mechanism.

The movable. part i made of, an arm l5, wh ch moves round an axis Hi. In the embodiment shown on the drawing the arm i5 is made as an an le and provided with an axis I1 fastened on said arm, a roll [8 being cradled on said axis. The roll is composed of a number of discs l9, spaced by washers 20 kept together by rivets 2i and abushing 22. The discs l9. which in the roll I8 are equal in number to the discs I in the cylinder 6, are, provided at their periphery with protuberances 23, which have been placed so on riveting the roll, that the protuberances on the different discs are ofiset in relation to each other. Between the protuberances of the first and second discs, there is a certain angular distance, between the second and third discs an equal angular distance, a s. 0. When the apparatus is in function and the roll I8 is being turned round step by step, the discs is can in their proper turns and only one at a time by means of some of their protuberances 23 mesh with the corresponding disc 1 in the cylinder 6 by means of the arm 24. The roll 18 is placed so in the apparatus, that its discs l9 come right in the same plane as the corresponding discs 1 in the cylinder 6. Between the cylinder 6 and the roll I8 there are arms 24, one for each disc in the cylinder, resp. the roll, placed so, that they come in the same plane as their respective discs, and turningly cradled on the axis l6. Said arms 24 serve to receive the friction appearing against the roll on the cylinder being turned round and to prevent the roll from following said motion.

Further, the roll I8 is provided with a toothed wheel 25, which is. meshed with another toothed wheel 25 cradled on the axes [6. The cylinder 6 has a disc 21 running against said toothe wheel, said disc being provided with a tooth 28, Fig. 5, ch, after the cylinder having revolved one rn, actuates the toothed wheel 25 and moves it forward one step- Thus the roll l8 also tu s on .each other in the roll l3.

. in the same plane as the step corresponding to the angle between the protuberances 23 between two discs l9 lying near The arm I5 is held in such a position by means of a spring 29, that the roll l8 rests permanently against one of the arms 24, which are thus pressed against the cylinder 6.

The embodiment shown on the drawing refers to an apparatus for making regulations automatically at predetermined times in some other apparatus, sending time signals or the like. The apparatus is hereby driven in a suitable manner, for instance by a clock mechanism, the motion of which is propagated by means of the toothed wheel 14, Fig l, to the toothed wheel l3 fastened on the cylinder 6, which is thus turned round its shaft 5. The motion may either be smoothly continual or arranged step by step so that the cylinder 6 is turned an equal space for each time period. The time periods may be minutes, tenth parts of the hour or another desired division of time. The division of the grooves H in the discs i must correspond to the turning angle of the cylinder 6 for its motion during a time period. If thus the first groove at the initial position of the cylinder is lyingright in the same plane as the head of the arm 24, the second groove must, after a turning motion forward corresponding to a time period, be lying atsaid place, after a second forward turning the third groove at said place, a. s. o.

The protuberances 23 on the roll iii are arranged so, that only one at a time can be right head of one of the arms 24. On the cylinder 6 having been revolved one turn, the tooth 28, Fig. 5, on the disc 21 meshes with the toothed wheel Ziiand turns it forward one step. The toothed wheel 25, which is fastened on the roll l8 and meshes with the toothed wheel 26, is thus also drawn forward one step, and so is the roll I3, the nearby lying disc 19, Figs. 1 and 2, thus meshing with its respective arm 24 by means of its protuberance 23. In said way all the protuberances of the roll l8 will mesh one after the other with their respective arms 24, which may thus be actuated by possibly inserted pins I2 in the discs 1 in the cylinder 6, which rests against them.

The grooves I i in the discs i are sixty in number in each disc in the described embodiment of the apparatus. If the time periods are to be tenth parts of the hour and the turning forward of the roll corresponds to the angle between two grooves in the disc I, the roll will then revolve one turn during six hours and four turns during twentyfour hours.

To mark each tenth part of the hour, four discs I are needed in the cylinder 6, said discs one after the other being able to be meshed with corresponding arms 24 and discs IS in the roll i8. Owing to the roll l8 being moved one step forward for each turn of the cylinder 5 corresponding to the dividing angle between the protuberances 23 on the discs I9 lying close to each other in the roll I8, the discs [9 will, for each such motion forward of the roll, one after the other mesh with the corresponding disc in the cylinder 6 by means of their protuberances 23. After the cylinder having revolved four turns the pair of discs will again mesh and thereafter, for each turn of the cylinder, the second,third, fourth a. s. 0. pair of discs for each day on which the time signals are to be given at the same time. If the signals are to be given at other times on certain days, four further'discs will be inserted in the cylinder and as many corresponding discs e in the roll for each day, on which the signals are to be varied.

The embodiment shown on the drawing shows an apparatus, in which the signals are to be given at the same time six days of the week and at other times one day of the week. As well the cylinder 6 as the roll l8 are provided with two sets of four discs each. The roll I8 is arranged so by said embodiment, that it revolves one turn a week on its above described motion forward step by step. The divisions between the protuberances are arranged so, that the first four discs mesh: with the corresponding discs in the cylinder ii during six days of the week in the above de-- scribed way, and the second set of four discs on the seventh day.

represent a certain time. In the grooves corresponding to the times, on which the signals are wished to be given, the pin I2 is inserted. On the pin l2, Fig. 4, during the revolving of the cylinder 5, passing some of the arms 24, which is held meshed'against the cylinder 6 by means of the protuberance 23 on the disc iii, the head of the pin 12 will actuate the arm 25 and thus also the roll l8, which is then radially removed from the cylinder 6. The movable part, the arm l5, which is connected to the roll 18 by means of the axis 11, then revolves round its axis is, and said motion can be used for actuating a suitable device for sending a signal, etc. On the further revolving of the cylinder 6, the pin I2 passes the head of the arm 24, the movable part, the arm l5, together with the roll l8 then being by means of a spring 29 drawn back its initial position, where it remains until the next pin [2 passes, the same motion then repeating itself.

Fig. 3 shows the position of the arm 24 between the protuberances 23 on the discs 19 in the roll l8, which are not meshed with the head of the arm 24 by means of some of the protuberances 23. As appears from the drawing the pin l2 in the cylinder 6 may in said case pass the head of the arm 24 without the roll IB- being actuated, since the arm has enough free space in the recesses between the protuberances 23 in the discs [9.

Though I have described an apparatus, in which the cylinder 6 and the roll l8 have been composed of a number of discs, the cylinder as well as the roll may naturally be made solid and provided with holes for the pins I2, or the discs be ring shaped, etc.

I claim:
