1. Notice also that there are small metal pins sticking up 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 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 14 15 Hanging The Weights The weight cord will probably require some adjustment to enable it to hang evenly This is accomplished by rotating the corresponding cord terminal until any twists have been unwound The cord should be made to hang as straight as possible 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 out of the groove allowing the weight to fall rapidly potentially damaging the clock Before hanging the weights please double check to ensure that the cord is sitting in its groove in the drive arbour Sorry to keep going on about it Slip2.

4. fitting of the clock as the delicate wheels have been known to snag on such garments 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 The clock needs clear space beneath it for the weight to fall it also looks at its best if it has a good deal of empty wall around it 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 cho sen wall is less vertical than you had thought if so please contact me so can provide you with a modification kit tailored to your needs The clock is susceptible to temperature changes gradual changes affect timekeeping frequent sudden and extreme swings in tem perature can damage the clock For this reason the clock should be placed away from radiators If the clock can be kept in environment with a broadly even temperature so much the better Significant draughts can affect the clock badly interfering with the swing of the pendulum A hallway is a poor location for the clock being exposed to gusts of outside air when the door is opened The clock does of course make a noise It has a pleasant s
5. g tape round the drill bit will give you the right depth Be aware of how well the drill goes in the plaster layer is drilled very easily and the drill can wander before it meets the brick below It should encounter decent resistance when it reaches the brick if not you may have found a mortar join which could be quite weak It also is possible that the wall has deteriorated in either case it is not wise to hang the clock here lf the wall proves to be sound tap the red plastic wall plug fully into place slip the screw through the wooden mounting peg and screw it to the wall making sure it is solidly held and can t be rotated Stud walls plasterboard over a wooden frame Try to locate one of the vertical wooden studs by tapping on the wall Fixing the clock to one of these is straightforward and reli able if you find one in a good position Drill a hole with a 2 5mm twist drill bit and use the 50mm x 4mm 2 x 8 screw to hold the mounting cone securely to the wall If you are unable to find a suitable stud you will need to use the cavity wall fix ing You have been provided with an M3 x 50mm toggle fixing which you will have to unscrew slide the mounting peg onto and reassemble A 10mm drill bit will be needed to make the hole in the plaster board Lath and plaster walls Walls of this type are old and may well be weak If you are confident in yours use the M3 x 50mm toggle fixing as above but take great care to en

7. low tick tock that many find relaxing Some people find that they cannot easily sleep in a room with a ticking clock others enjoy the sound If you enjoy listening seriously to music in your home you may wish to keep the clock apart from the Hi Fi Opening the Crate The crate that contains your clock is a singularly scruffy bit of wood work Please protect the surface you intend to place the crate upon by spreading an old towel first To open the crate a medium crosshead screwdriver is required Remove the four screws securing the lid and remove it Locate and set aside the bag contain ing the drive cord the mounting peg and the pendulum joining peg The mounting peg will be needed as soon as the correct wall fixing has been decided upon and a suitable hole has been drilled in the wall Pendulum Joining Peg Mounting Peg The clock hangs from a single screw which must be firmly fixed into the wall The mounting hole should drilled at roughly eye level A selection of screws plugs and other fixings is provided with the clock you will need to choose the appropriate one to suit your wall If after reading the following you are unsure of how to proceed please contact me Drilling the Mounting Hole Sound brick or stone walls A well secured 50mm x 4mm 2 x 8 screw will hold the clock admirably in walls of this nature Use a 6mm masonry drill bit to drill the hole in the wall to a depth of 55mm a bit of maskin
8. oth sides The Illustrations below show which direction to move the clock to bring it into balance Make small adjustments carefully observing the movement of the pallets in and out of the teeth In the first few days after installation it is wise to check this adjustment every now and again indeed the clock can gradually wander out of beat over time Should the clock start to misbehave the adjustment of the beat is the first thing to check AN The clock should now be running in beat producing a balanced tick tock tick tock sound rather than tick tock tick tock tick This is a precise adjustment expect to spend a little time making sure that the swing of the anchor in and out of the escape wheel is the same on both sides 18 Timekeeping To adjust the clock hands First grasp the adjuster and press it towards the clock this disengages the hands from the main movement Rotate the adjuster clockwise while continuing to press the hands follow Set the time The clock is capable of keeping time accurately If the clock is running slow rotate the bobnut as shown in the left hand illustration follow the right hand illustration if it is running fast daily difference adjustment in minutes a turns difference adjustment in aa bobnut turns If the Clock Runs de If the Clock Runs Fast 19 Running The clock is designed to be wound at r

10. please hold the clock only by the wall bracket and the frame back plate as shown below it is tempting to pull the frame front to lift the clock but this will result in damage The frame back plate is wedged quite tightly in its foam lined wooden block so some pressure will be required to lift it free Allow the clock to be lifted as indicated by the larger arrow 11 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 When the clock is sitting on the mounting peg ensure that the frame back plate is right up against the wall then apply even firm pressure downwards The frame should move downwards with a satisfying clunk indicating that the clock is correctly mounted on its peg lt 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 the toggle fixing has been used In this case unscrewing 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 fi
11. sure that the arms open vertically so they can grip the laths well Unpacking the Clock Remove the parts one by one when you are ready to fit them You ll need a screwdriver to remove the individual parts from the crate be sure to put any detachable parts of the packaging back in place before they are lost The empty crate can be stored flat or rebuilt into its original shape Remove the two screws indicated to allow this end of the crate to fold down this end holds the NN weight and is quite heavy Now remove the single screw indicated and fold down the side of the crate And now remove the final screw be aware that this screw holds the last two sides of the crate in place which should be lowered simultaneously The Opened Crate and its Contents Clock Movement Lower Pendulum Weight Counterweight Removing and Handling the Clock The main body of the clock is robust but needs to be removed from the crate carefully The clock is held in place in the crate on a mounting peg similar to the one now fixed to the wall The clocks back plate is held firmly in a foam lined wooden block to prevent movement while in transit The upper pendulum rod is kept from wobbling around by a screw this needs to be removed before the clock can be lifted from the crate The clock can now be eased gently off the mounting peg by applying pressure on the wall bracket as indicated by the arrows At this stage
12. tted 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 Be sure you have the pendulum facing forwards it might not fit properly otherwise The two tiny wooden pegs visible on the circular pendulum joiner should be to the rear Lift the lower pendulum inserting the end of the upper rod into the joiner Slip the pendulum peg home making sure it goes as deep as possible 12 13 Fitting the weight cord This simplified illustration shows the a close up of the weight cord shown in cerise 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 winding arbour
13. y jiggle it in and out and repeat for the intermediate wheel Now rotate the clock hands a full 12 hours before setting the time and re starting the clock Normally these methods will enable the clock to return to its nor mal stable running If it continues to require frequent re starts however it may need to be returned to the workshop Please do not hesitate to get in touch if you experience any difficulty with the 20 clock 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 crate the old towel pillow and crosshead screw driver used when the clock was first unpacked Have the opened crate lying on an old towel ready to accept the parts as they are removed Wind the clock so that the main weight is quite close to its high est position as shown Set the time to read 12 00 1 6 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 off the right hand pulley 6 4 If the clock is being returned to the workshop our telephone discus sion 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 safel
14. y outside the crate If the entire clock is being packed screw the weights in their places now wind up the cord and bag it Now place the pillow on the floor under the clock and dismantle the pendulum by removing the peg the lower half of the pendulum is now free to fall but might require a little tug This item may also not need to be returned to the workshop 2 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 whereupon it can be lifted free of the mounting peg The clock can now be placed in position in the crate Please ensure that the clock is only handled by the back plate and bracket as it is eased into place locating with the crate mounting peg first then slid 3 down to be held by the foam lined wooden block Screw the upper pendulum in place within the crate 21 If the entire clock is to be packed please ensure that all the various fixing pieces are located securely holding their respective parts in place If the clock is now to be stored please be aware of its environment It can withstand wide temperature variations but storage at an even cool room temperature is preferred The clock does not like frequent rapid changes in temperature Please ensure t
