1. Dismantling the and Re packing the Clock At some time it will be necessary to dismantle the clock for storage moving house or returning to the workshop for maintenance You will need the original packing Wind the clock so that the main weight is above half way as shown Set the time to read 12 00 1 Stop the clock by gently arresting the pendulum bob 2 Remove the counterweight 3 followed by the drive weight 4 Remove the cord terminals from the frame 5 Slip the cord off the left hand pulley first allow it to drop under the clock then lift it from the right hand pulley 6 If the clock is being returned to the workshop our discussion will have clarified which items need to be included probably just the clock mechanism If this is the case the weights will need to be stored safely outside the crate If the entire clock is being packed put the weights in their places now wind up the cord and bag it Place the pillow on the floor under the clock and dismantle the pendu lum by rotating the adjusting ball until the lower pendulum comes free This might not need to be returned to the workshop either The clock can now be lifted from its peg it may well be hard to re move First grip the back plate and ease it from side to side Place one hand over the top of the clock gripping the bracket sides and push the back plate upwards with the other hand A gentle side to side rocking motion will free the clock whereu
2. delicate wheels have been known to snag on such garments Causing damage trauma and the need for repairs A Suitable Location for the Clock The clock can be successfully located in many settings however a few simple precautions need to be taken The clock protrudes from the wall by nearly 200mm 8 inches and is delicate It must be placed so as to exclude the chance of someone accidentally brushing against it Alcoves are nice e The clock needs clear space beneath it for the weight to descend The clock measures 1 3m 4 3 from the very top to the bottom of the large weight at its lowest The hands sweep through a diameter of 300mm 12 s The wall it is mounted on does need to be vertical If your wall is wonky the clock can be modified to suit we will have discussed this before your purchase You may find upon installation that your chosen wall is less vertical than you had thought if so please contact me so can provide you with a mounting kit tailored to your needs The clock is susceptible to temperature changes gradual changes affect timekeeping a little frequent sudden and extreme swings in temperature can damage the clock For this reason the clock should be placed away from radiators If the clock can be kept in environ ment with a broadly even temperature so much the better e Excess moisture Is to be avoided the clock should not be located In a bathroom or a kitchen The clock does of c
3. fixing as above but do take care to ensure that the arms open vertically so they can grip the horizontal laths well Mounting the Clock While handling the clock please avoid touching the wheels at all times The clock is best held by the upper part of the frame front and the top of the wall bracket Notice the keyhole shaped slot in the rear of the back plate the lower circular part of this slot will engage with the mounting peg on the wall peg ensure that the frame back plate is right up against the wall then apply even firm pressure downwards H When the clock is sitting on the mounting The frame should shift downwards with a satisfying clunk indicating that the clock is correctly mounted on its peg It may prove difficult to press the clock into place in this case it should be lifted and put to one side momentarily The peg will need to be unscrewed and the optional plywood spacer should be employed This is further complicated if a cavity wall toggle fixing has been used In this case un screwing the peg will cause the toggle part to be lost in the wall this is why you have been given two Fitting the Pendulum The lower pendulum can now be fitted to the clock Placing a pillow on the floor under the clock is a wise precaution at this stage the pendulum bob is filled with lead and is heavy it would be damaged should it fall to the floor So would the floor Toes too
4. nearer of the two loops in the cord and apply a little downward pressure as you hang the large drive weight in the other loop Now hang the counter weight in the nearer loop The clock is wound by placing a thumb in the counterweight hole and pulling downwards lifting the drive weight A good deal of force is required to raise the weight expect the ratchet mecha nism to make a moderately loud noise during winding 12 13 Adjusting The Clock The clock must now be adjusted to bring it in beat Simply put this means that the clock ad escapement should be running evenly The escapement is the name given to the two uppermost moving parts of the clock the very top part which rocks back and forth is called the anchor the wheel directly beneath is the escape wheel The anchor has two pallets these are the parts which make contact with the escape wheel Your clock features a new de sign of escape anchor which is much simpler to adjust than earlier versions Once you are happy that the clock looks vertical gently move the pendulum as far as possible in the direction shown The tip of the left pallet will touch the land between two escape teeth shown opposite top The pallet touches the bottom land between two escape teeth as expected Now release the pendulum which will swing in a wide arc During the first few swings the escapement self adjusts the pendulu

6. out of the bottom of this groove these hold onto the cord and stop it the slipping through the groove Wrap the cord up underneath the winding arbour then over the top of the angled pulley and down in front of the frame Bring the cord back up and insert the other terminal marked L in its hole Before hanging the weights in their loops make certain that the cord is snugly seated in the arbour groove by pulling gently on the sections marked A amp B simultaneously Now check that the cord runs evenly and remains in the groove by pulling B down while letting A up gradually The loops should hang evenly as shown in the illustration on the right 10 11 Hanging The Weights The weight cord will probably require some adjustment to persuade it to hang evenly This is accomplished by rotating the corresponding cord terminal until any twists have been unwound This needs to be done to avoid a perilous situation small twists in the cord can gradually work their way round to the winding arbour and eventually cause the cord to ride up out of its groove The cord can then slip com pletely out of the groove allow ing the weight to fall rapidly po tentially damaging the clock the weight and anything it lands on Before hanging the weights please double check to ensure that the cord is well seated in its groove in the drive arbour Sorry to keep going on about it Slip a thumb into the
7. Be sure you have the pendulum facing forwards the two small screws in the circular pendu lum joiner should be to the rear Lift the lower pendulum inserting the end of the upper rod into the joiner Rotate the captive wooden ball be tween thumb and forefinger to con nect the two pendulum halves One twist of the ball between thumb and forefinger is about one third of a full rotation 30 of these twists will bring the pendulum about half way up its available range of movement Fitting the weight cord This simplified illustration shows the a close up of the weight cord shown in mauve fitted around the two pulleys and the central winding arbour with the great wheel behind The sequence that follows shows how the cord is laced within the clock In these images the lower clock frame has been shown as a translu cent grey block to indicate the sec tions of cord that go in front of the frame and those which go behind The cord terminals light blue in the illustrations are marked L amp R first fit the one marked R into the right hand hole in the frame as shown On the left side of the clock in between the frame and the great wheel loop the cord over the left hand pulley Al low most of the cord to fall to the outside forming a long loop as shown on the right Notice how the cord lines up with a groove in the central drive arbour Notice also that there are small metal pins sticking up
