Figure 6 is a section taken along the line 6-6 As long as the pin 31 is away from the trip arm of Figure 2, 28, the pins 30 will always be engaged with the Figure 7 is a section taken along the line 7-7 slots 17. However, when the pin 31 which is fasof Figure 2, tened securely to the pulley 21, strikes against 55 Figure 8 is a side view of the clock and apthe upwardly projecting and slanting portion 36 of the trip arm 28, it will be seen that the trip arm 28 will be pivoted about the shaft 29 and the pins 30 will come out of engagement with the slots 17. As soon as this action takes place the pulley 21 will tend to turn the power roll 16 and the paper 14 will be wound up on the roll 16 on account of the frictional engagement between the pulley 21 and the fibre disc 22. This action will take place until another'pair of slots 17 engage with the pins 30, when the pins 30 will drop down into the slots and in case the spring mechanism continues to run, the strength of the paper itself will prevent the roll 16 from further rotation and the friction disc and the pulley 21 will still revolve, however without rotating the power roll 16 since the pulley 21 willslide freely along the friction disc 22.

A spring 37 is pinned to the trip arm 28 as shown and this spring provides the proper function for raising or lowering the trip arm 28 under 7 spring action.

When the pins 30 are not engaged with the slots 17, they will merely travel along the paper strip 14 and are made slightly blunt at their ends so as not to tear into the paper.

An extra idler pulley 38 is provided to allow more convenient take-up of the paper roll on the power roll 16.

It will be seen from our construction that the movement of the daily register will be strictly uniform and in no way can it get out of place, since by means of frictional devices as shown in combination with the slots and tripping mechanism, this register will move uniformly between slots for a brief interval of time between days.

The pulley ratio between the pulleys 21a and 21 are such that a complete winding of the alarm mechanism of the clock or other intermittent power device'will not cause a complete revolution of the pulley 21, otherwise the tripping device would function more than once daily. Furthermore, the tension in the spring 3'7 is such that even though the pulley 21 would revolve slightly more than once, this tension would tend to prevent the pin 31 from passing beyond the slanting portion of the fulcrumed arm since the power of the alarm or other device would be weakest at this point.

In case it is desired to make an entry for an appointment to be kept at a future date, the pullhandle 39 is provided. This handle 39 engages with the front end of the clock by means of the snap springs 40 and 41. When it is desired to make the entry for the future date, the handle 39 is pulled out and is pulled forward until the date desired appears in the opening 11 and the entry is made at its proper place. Meanwhile the paper 14 rolls about the idlers 32, 33, and 34, and feeds from the feed roll 15. After the entry is made, the feed roll 15 is reversed and turned back to the present date by means of the knurled thumb screw 42 and then the pull handle 39 is snapped back into position.

It will be seen from our construction that when the date is changed as mentioned, the paper cannot pull from the power roll 16 since the slots 17 will be engaged with the pins 30.

Adjustments of the power roll can be made by means of the knurled thumb screw 25.

The driving pulley cord 20 passes over suitable pulleys 44 positioned at the proper angle to transfer the cord from one plate of the spring pulley to the power roll pulley.

A spring 45 is provided to keep the feed roll 15 under proper tension. This spring is pinned to the opposite chassis walls 46 of the clock and the same spring is pinned at its outer ends to the friction disc 47 which travels against the flange 48 of the feed roll 15.

In the same manner, the spring 49 is fastened to the chassis wall 46 of the clock and at its outer ends to the friction disc 50. These springs are merely strips of suitable spring metal.

In Figure 7, it will be seen that the actual tripping mechanism is on the righthand side of the clock case while there are pins on each side. This is necessary since the slots are arranged on both sides of the paper roll so there will not be a tendency for the paper to twist when being rolled, on the rolls, and provides uniformity in rolling.

The conventional base supports for the clock are shown at 51.

It will be seen that in operation, all that is necessary to do in the clock is to wind the alarm mechanism daily and set the arrangement for a specified time, preferably at night. In this way, the device requires no further attention since it will automatically change its register in a brief interval at night and will be ready the next morning for reference as to appointments.

It will also be understood that the same motive means can be applied in the case where it is desired to use electrical clocks, as shown in Figure 8, or other clocks driven by weights and so forth.

It will be seen that we have arranged this device in the simplest manner to accomplish the result desired and that the result is an appointment clock and arrangement convenient to make entries upon at any present or future date and which arrangement operates automatically and independent of constant adjustment with the exception in the case of the mechanical clock of the winding of the alarm key, and it will be further seen that these elements have been arranged in the simplest practical manner for economical manufacture.

Some changes may be made in the construction and arrangement of the parts of our invention Without departing from the real spirit and purpose of our invention, and it is our intention to cover by our claims any modified forms'of structure or use of mechanical equivalents, which may be reasonably included within their scope.
