Jauch clock movements have little identification markings to go. Often it will be as simple as a 77 or 78 before some other numbers. It may only say PL 77 or PL 116 also. If the movement says Jauch and some other numbers, it is the Jauch clock movement company who made it.

CONTENTS

1. Clock
2. Glass cover
3. Pendulum
4. Envelope containing a) Instruction booklet, b) Key, c) Spare suspensionwire

IMPORTANT

The cover of this clock is made of unbreakable glass. To clean off dust,etc. only use a very soft cloth or feather duster, thus avoiding scratches.

METHOD OF ASSEMBLY

1) Set the clock upon a level surface completely free from vibration.

2) There is a brass protruding tube located at the back of the clock throughwhich passes a delicate suspension wire assembly (Figure I). The tube hastwo sections, the lower part (A) holds the suspension wire in position whilethe clock is in transit.

3) The lower section of the tube is held tight by a thumb screw (B). Loosenthis screw and raise the lower part of the tube (A) upward as far as it willgo, then tighten the thumb screw (B). The suspension wire assembly is nowready to receive the pendulum.

4) Take the pendulum and place the top of it over the suspension plate (C,figure I), located at the end of the suspension wire . . . be extremely carefulnot to bend the delicate suspension wire. Make certain that the bottom pointof the pendulum hands directly over the cone of the brass cup, otherwise theclock is not level. Accurate leveling is accomplished by adjusting the levelingscrews (K) protruding from the base of the clock.

5) When pendulum is stationary, rotate it slightly either to the right orleft, approximately one half turn, then release.

6) HAND SETTING – The clock should be set to the proper time by movingthe minute hand. Do not touch the hour hand as this moves automatically.

7) WINDING: -- Clock winding is a memorable anniversary for many familiesthe world over. To some, New Year’s Day is ideal; others honor the dateof anniversary of a wedding, birth, or special family occasion with this sentimentalcustom. For testing and regulating purposes, the clock has been one thirdwound before leaving the factory. To wind fully, give the spring 3 to 4 furtherturns with the key. Please turn anti-clockwise. Do not force the spring, windonly until you find that the key will not readily turn further. when fullywound, your Schatz clock requires no further winding for 400 days.

8) Carefully place the glass dome into position, covering the clock.

9) To prevent loss, keep instruction booklet and key under the base of clock.

TIME REGULATIONS

ALLOW CLOCK TO OPERATE 48 HOURS BEFORE ATTEMPTINGTIME ADJUSTMENTS

10) the cup located on the base centers the pendulum . . .if the pendulumtouches the side or bottom of the cup, the clock will not operate accurately:This indicates that the clock does not stand on a level surface. In such acase accurate leveling is accomplished by adjusting the leveling screws (K)protruding from base of clock, enabling pendulum to rotate freely and theclock to operate satisfactorily. The cup also prevents the pendulum from swingingtoo much when the clock is moved . . . thereby preventing damage to the glassdome or suspension wire.

11) On the top of the pendulum is a disc (figure III), on which numbers areengraved 1 – 16 and two arrows marked F-S. the small indicator hand(L) will be pointing to a number on the disc at which the clock was regulatedbefore leaving the factory. Should you find it necessary to regulate the clockobserve the number to which the indicator hand points. The distance betweeneach number is equivalent to 1/2 minute in 24 hours + or -.
For example: If your clock loses two minutes per day (24 hours) and the indicatorhand points to number 8 on the disc – move the disc on the directionof the arrow marked F until the indicator hand will point to the number 4.

PUTTING THE CLOCK IN BEAT

12) In some instances, the clock may be 'out of beat': this shouldbe rectified by an experienced clock-maker. This can be determined as follows:

Observe the lever and escape wheel through the two holes in the back plate.When the lever (pallet) leaves a tooth of the escape wheel, the pendulum mustrotate a litter further. The pendulum will then rotate to the opposite sideand will also rotate a little further after the lever leaves a tooth of theescape wheel. If the distance the pendulum travels is unequal at both endsof the rotation, the clock is 'out of beat'. To put the clock 'inbeat' the method is as follows: On the back plate is a bridge (D) underwhich a small round pillar is attached and held by screw (F). The suspensionwire is held in place by a small bracket centered within this pillar. Screwedto the suspension wire at a slightly lower point is fork (E), which guidesthe lever. Loosen screw (F), turn the small pillar slightly, with the helpof the protruding arm (G) in the direction that more rotation is wanted, tomake it equal. Tighten screw (F).

SUSPENSION SPRING REPLACEMENT

In the event of breakage of the delicate suspension wire, which holds thependulum, a spare has been included for your clockmaker to use if it shouldbe necessary to replace the suspension wire. This is replaced in the followingmanner:

13) Take the pendulum off the suspension plate (C).

14) Remove thumb screw (B) of suspension wire protecting tube slide (A).Now remove the protecting tube slide.

15) Remove the suspension wire mounting bridge (D) with the attached suspensionwire assembly by removing the two holding screws (I). Lift bridge and attachedsuspension wire assembly up and out of protecting tube. Remove the suspensionwire assembly from the bridge by removing thumb screw (H).

16) Replace the suspension wire assembly on the clock, reversing the procedureof removal. Be sure that the fork (E) fits over lever.

17) Clock must be put 'in beat' again, as explained in 'TimeRegulations', paragraph 12.
