TIME RECORDING INSTRUMENT Original Filed Jan. 24, 1925 w eo f 9 g Patented Feb. 11, 1930 PATENT OFFICE JULIUS BRENDLE, OE ZURICH, SNITZERLAND TIME-RECORDING INSTRUMENT Original application filed January 24, 1925, Serial No. 4,523, and in Switzerland June 16, 1924. Divided and this application filed January 12, 1828. Serial No. 246,367.

The present invention relates to improvements in time-recording instruments and is a division of my application Ser. No. 4,523, filed January 24, 1925.

In particular the invention has reference to the indicating device in a workmans timerecorder; in which the type device driven by a driving train is provided with a divison taking into account the non-working periods for indicating the efiective working time.

The subject matter of the present invention difiers from that of the above mentioned application in that a wheel of the recording type device which is continuously rotated by 5 the driving train is provided with teeth interrupted in accordance with the non-working periods for the purpose of interrupting the stepping of a recording type member (which may be a type wheel or a type lever).

constructional example of the subject matter of the present invention is illustrated on the accompanying drawings which show in elevation only those parts of the constructiona1 example which are necessary for explaining the invention,

lVith further reference to the constructional example illustrated 1 denotes the type wheel rigidly mounted on the shaft 2 and provided with printing types 8, the figures on ;o which form a consecutive scale of units oi the working time, for instance tenth of working hours and the numbering being 0.0, 0.1, 0.2, 0.3 1.0, 1.1 up to 12.00 indicating 12 working hours.

5 A stepped movement is imparted to the type wheel 1 by means of a twoarmed ratchet lever 4 turnably mountd on a pin 6 fixed to the plate 5. The ratchet lever 4 carries at its one end pusher pawl 7 which is urged by 0 means of a spring 8 against pins 9 arranged in a circle on a disc 10 rigidly connected to the type wheel 1. The number of pins 9 corresponds to the number of printing types 3 arranged on the type wheel 1. The other arm 5 of the lever 4 is a pawl 11 cooperating with a ratchet disc 12 and urged against the latter by the spring 13. The disc 12 is rigidly mounted on a shaft 14 which is continuously driven by a clock-work not illustrated in the direction of the arrow shown in Fig. 1 and the circumference of the disc 12 is provided with toothed portions 15 corresponding to the working time and blank portions 16 which correspond to the nonworking intervals.

During the working time the teeth of one or the other of the toothed portions 15 of the disc 12 cooperate with the pawl 11 and every tooth causes a rocking movement of the lever 4 against the influence of the spring 13. Thereby the pusher pawl 7 cooperating with the pins 9 causes a turning movement of the type wheel 1 through a determined angular extent whereupon the pusher pawl 7 is in a position to cooperate for instance with the next pin 9 and so on.

The angular stop movement of the type wheel imparted by each action of the ratchet lever shall occur after every 6 minutes. If I designates the beginning of the working time for instance 7 ocl. a. m., the blank portion P-I on the ratchet disc 12 will have reached the pawl 11 of the ratchet lever 4 at 8.48 a. m. after eighteen ratchet movements of the lever 4 and thereby after eighteen step by step movements of the type wheel I, the blank portion I b corresponds to the breakfast interval. The ratchet lever 4 is now not operated by the ratchet disc 12 and the type wheel is not turned until the first tooth of the toothed portion beginning at I has reached the pawl 11 during the further turning motion of the disc 12 under the actuation of the clock work. With the peripheral extentof I**I shown in Fig. 1 this will happen at 9 a. m. when the intermittent turning movement of the type wheel 1 starts again.

The ratchet lever 4 is again inoperative at 12 ocl. when the beginning of the blank portion II-III of the circumference of the disc 12, which corresponds to the midday interval, has reached the pawl 11. At 1.30 p. m., i. e. when the toothed portion starting at III acts upon the pawl 11 the intermittent turning of the type wheel is again effected until 5 ocl. p. m., when the blank portion between IV and I comes to cooperate with the pawl 11.

The peripheral extent of a blank portion VI corresponds to two hours and this portion may be used for actuating the ratchet lever 4 by screwing a toothed segment to the disc 12, whereby the type wheel indicates these time units as over-time. In consequence of the blank portions in the ratchet disc the type wheel is only turned during the effective working time and it indicates the latter.

The toothed portions on the ratchet disc 12 which take into account the intervals in the working time by their peripheral distance from each other may also be detachably secured to a ratchet disc in a similar manner as has been disclosed in my above mentioned application, so that the segments might be exchanged for others the toothing of which corresponds to difierent units of time or shows a diiierent peripheral extent to take into account non-working periods of a diiierent duration.

I claim:

1. In a workmans time recorder, a type wheel having a series of concentric time divisions, a uniformly rotated wheel having a series of teeth corresponding to said time divisions but interrupted in accordance with non-working periods, and an operative connection between said type wheel and said other wheel for imparting rotation to the former, said type wheel directly indicating the working time.

2. In a workmans time recorder, a type wheel having a series of concentric time divisions, a ratchet wheel having a series of teeth corresponding to said time divisions but interrupted in accordance with non-working periods, and means to control the rotation of said type wheel from said ratchet wheel, said type wheel directly indicating the working time.

In testimony whereof, I have signed my name to this specification.

JULIUS BRENDLE.
