RE INK A GIBSON TICKET MACHINE RE INK A GIBSON TICKET MACHINE GIBSON A14 TICKET MACHINE Many LONDON TRANSPORT Gibson ticket machines printed over 5 million tickets in their service life,and a Gibson would have been opened and re inked over 100 times ,They served LONDON TRANSPORT for nearly 40 years,with over 650 components they are a truly superb ticket machine.A credit to LONDON TRANSPORT and the designer GEORGE GIBSON(LONDON TRANSPORT TICKET MACHINE SUPERINTENDENT)Some machines may be fitted with normal screws so there is no drilling process required,but most Gibsons will be fitted with the correct tamper proof shear screws 27210199 RE INKING YOUR GIBSON Opening a Gibson is straight foward,you will need experience using a drill.Read the instructions through ,if you need any help or info just e mail the site,The machine will need to be gripped whilst drilling,so make sure the machine is safely secured whilst drilling. 27210213 FARE DIAL SHEAR SCREW YOU WILL NEED A DRILL AND 2MM DRILL BIT,Make sure you drill in a straight line,and drill in stages ,so you can check depth etc ,drill down approx 1mm, Take your time ! 27210200 DRILLING IN TO THE MACHINE USE 2MM DRILL BIT sit the end of the drill bit on to the shear screw,score a guide with the drill bit in the middle of the screw,then drill with slight pressure until you are approx 1mm in depth 27210201 DRILLING OUT THE SHEAR SCREW Drill in a nice straight line,untill you get approx 1 mm depth,insert screwdriver etc,into the drilled hole until nice and tight then simply unscrew. 27210214 USE A FILE If you intend to open Gibsons on a regular basis you can make your own special tool from a pointed needle file,just ground down the end of the file until it has a flat end of approx 1.8mm ,this fits very tight in to the 2mm hole made by the drill bit and turns the screws with ease, 27210215 SHEAR SCREW REMOVED FROM SIDE DIAL Once screw removed,pull of cap and then fare dial. 27210202 REMOVAL FARE DIAL The fare dial may be stiff ,due to the chaps at L.T placing a small piece of ticket on the shaft to take any play out of the fare dial,try to do the same if you can. 27210203 REMOVAL SIDE CASE Remove both screws,the side case is now ready to be removed 27210216 REMOVAL SIDE CASEING Hold the machine tight and pull of the side case,a bit of maneuvering may be required, 27210204 REAR SHEAR SCREW REMOVAL The 2 shear screws in the bottom/ middle of the machine need to be removed ,these screws hold the front plate to the rear of the machine ,and need to be removed before the front plate can be removed. 27210225 Use a 2mm drill bit,and drill down approx 1mm 27210217 REMOVING REAR SHEAR SCREWS a standard screwdriver with a edge less than 2mm can be used to remove screws,you may have to angle the screwdriver to get gripp/bite 27210218 REMOVING FRONT PLATE Once the screws have been removed the front plate is now ready to slide off the machine 27210219 FRONT PLATE REMOVAL The front plate needs to be removed to access the ink roller and is secured by a long screw seen in centre of picture,this ia a tricky little screw and needs to be made loose but not completely removed 27210226 FRONT PLATE REMOVAL Turn screw anti clock wise, make sure you use a decent strong screwdriver . 27210227 FRONT PLATE REMOVAL Slide off front plate but leave screw in position shown for the re fitting of front plate you cannot completly take out the long screw,as it will catch on the fare wheel 27210220 SLIDING OFF THE FRONT CASING Once the rear shear screws have been removed then slide off the casing to the left hand side as in picture, the front plate will not come off straight as the long screw is in the way ,it needs to slide on and off the machine as illustrated 27210221 ACCESSING THE INK ROLLER ONCE FRONT PLATE HAS BEEN REMOVED,POSITION THE MACHINE AS IN PHOTO,MAKE SURE THE MACHINE IS SECURE BEFORE RE INKING 27210228 PROP THE MACHINE UP AT A ANGLE PROP THE MACHINE SO WHEN RE INKING THE ROLLER YOU CAN SEE THE ROLLER BEING INKED CORRECTLY AND FOR INSPECTION OF MECHINISMS FOR LIGHT LUBRICATION 27210229 APPLY OIL BASED INK TO MACHINE ROLLER Apply ink to the roller with a small paint brush,apply the ink evenly to the roller turn roller with brush to make sure cpmplete cover of roller this will need to be done a few times,it is advised not to issue a ticket for a good few hours ,WHILST YOU HAVE THE MACHINE IN THIS POSITION YOU CAN LUBRICATE THE MACHINE ,DO NOT OVER OIL,VERY LIGHTLY APPLY OIL TO MECHINISMS DO NOT OIL THE CLOCKS ON THE FARE WHEEL MECHINISMS,AND YOU CAN ALSO CLEAN PRINT FACE WITH WD40 AND A TOOTH BRUSH ,BE CAREFULL NOT TO GET ANY OIL ETC NEAR THE ROLLER AS THIS WILL SMUDGE TICKETS 27210222 RE ASSEMBLE THE MACHINE HERE ARE THE REPLACEMENT SHEAR SCREWS THAT NEED TO BE RE FITTED,THEY JUST SCREW IN LIKE NORMAL SCREWS,THIS SITE IS ALWAYS AVALIABLE FOR HELP AND ADVICE 27210223 SLIDING THE TOP PLATE BACK IN PLACE YOU HAVE TO SLIDE THE FRONT PLATE BACK OVER THE LONG SCREW SHOWN ,AND THEN SECURE,IF YOU ARE NOT USE TO THIS THEN IT CAN TAKE A FEW ATTEMPTS BUT YOU WILL GET THERE IN THE END 27210224 LONG FRONT SCREW HERE WE CAN SEE THE LONG FRONT SCREW AND THE TOP OF THE FRONT PLATE,THE FRONT PLATE SLIDES ON TO THE LONG SCREW WHICH SLIDES THROUGH THE HOLE(JUST BELOW FARE WHEEL IN PICTURE) AND MUST LINE UP WITH THE THREAD ON THE OTHER SIDE ,AS DISCRIBED IN THE NEXT 2 PICTURES 27210230 RE SECURING FRONT PLATE WITH LONG TOP SCREW This is the most difficult part of the process and requires patience and accuracy as the front plate needs sliding back with the long screw lined up with the thread shown and needs to be lined up from the other side this can be a bit hit and miss,but you will find the thread after a few attempts 27210231 SECURE FRINT PLATE WITH LONG TOP SCREW When the long top screw has been aligned correctly It will screw in neatly as shown once this is done the front plate top is secure and the rear shear screws now need fitting. 27210245 RE FITTING FRONT PLATE Once the top long front screw is fitted correctly you can then re fit rear of front plate as in picture. 27210233 RE FITTING FRONT PLATE Fix shear screw until heads snap off ,the front plate is now correctly fitted. 27210248 RE ASSEMBLE FARE WHEEL re assemble fare wheel,fit shear screw and snap off, the machine is fully reassembled and will print approx 10,000
