SPECIFIFCATION

PETTY PATENT PIN JAMMER The following ststement is a full description of this invention in its best known form to me.

EDITORIAL NOTE NUMBER 89318/98 THIS SPECIFICATION HAS BEEN PUBLISHED AS FILED BY THE

APPLICANT.

I.1I_ lp--~l 1 This invention relates to the development of a new internal locking mechanism. Over the last few decades there have been numerous internal locking mechanisms. Some of the most noteworthy of these include:.

1) The pin tumbler mechanism 2) The tubular pin tumbler mechanism 3) The disc tumbler mechanism 4) The lever tumbler mechanism The warded mechanism The downfall of the internal locking mechanisms listed above and many others is that the thief already possesses a intimate knowledge of their operation in addition to the fact that they can be picked with two hands.

The advantages that the pin jammer has over its predecessors include: 1) Renders pick guns and slap picks obsolete 2) It can't be picked by the majority of commercial lockpicks which include a diamond pick, a small diamond pick, a ball or double ball pick or a warded key which all the above and many others can be picked by..

3) Requires a absolute mininum of three hands to pick 4. It is much harder to impression a key for than the above mechanisms.

If someone strikes the back or front of the restrictor it won't open as the restrictor will be held in position by the retaining plates.

e) Repairs are much simpler than on the majority of its predecessors.

7) It requires the key to be locked.

3 Accordingly this invention in its padlock form consists of A device called a restrictor which has indents in the end of it been forced by a spring that is attached to it so that these indents are engaging indents in the side of the skackle that becomes independent of the case when the mechanism is opened.

The restrictor is held in position by devices called retainers which engage indents running along the length of it on the front and back and it slides along these in a horizontal fashion relative to the keyway. When the mechanism is in a closed position the restrictor's indents(not the indents the retaining plates are engaging) are engaging the shackle's indents due to the the spring attached to it exerting a force on it. When the lock is opened it slides back along these retainers in a horizontal direction relative to the keyhole with the restrictor pushing back upon the spring. The restrictor's indents are no longer engaging the indents in the side of the shackle that becomes independent when the mechanism is opened. The shackle can now be pulled up.

On the front and back of the restrictor (the same sides the retainers are engaging the restrictor) are the pin chambers. The pin chambers are devices that house devices called pins that hang down and hit the the jammers if they aren't raised preventing the restrictor from been retracted back against the spring exerting a force on it.

The correct key raises the pins by devices protruding from it called pin raisers. These travel through the ward plates raising the pins so that as the restrictor is moved back the pins won't hit the jammers preventing it from been retracted.

4 The ward plates are basically a mirror image of the reatainers and differ only in that they are connected to the restrictor and move in conjunction with it as well as having holes for the pin raisers to go through.

The pin raiser travels through a hole in the ward plate contacting the pin tab and raising the pin which it keeps raised as it moves the restrictor back against the spring exerting a force on it. As the pin raiser moves across keeping the pin raised it will hit a device called the pin raiser jammer if it isn't shaped properly. If it hits the pin raiser jammer(hence been shaped incorrectly) it will prevent the restrictor from been retrated and the mechanism will remain closed..

The pin jammer is a stair case shaped formation protruding from the back and front of the case. The restrictor plate hangs down from the top of the case vertically. Attached to this is a device called the spring guard. This is merely a rectangular shaped device protruding perpendicularly from the restrictor plate surrounding the springs on all sides. On the back of the restrictor there is a square cutout. As the restrictor is retracted back against the spring the spring guard moves into the cutout and the spring is compressed against the restrictor plate.

Protruding from the top of the restrictor in a L-shaped fashion is the distance creator.

This protrudes through a hole in the side of the shackle that becomes independent of the case when the lock is opened. If it wasn't for this distance creator the distance that the restrictor would need to be retracted to free the shackle would be based merely on the size of the indents in the shackle.

On the base of the case surrounding the keyhole the areas have magnetic charges. When the mechanism is in a locked position the magnet is covering the bottom of the case denying access to the keyhole held on by the magnetic charge surrouding the keyhole.

The magnetically attracted device is surrounded on all sides(the front, back, right and left) by the case exstensions(this is so a pick can't be inserted between it and the magnet so as to pry it off.) Partially covering the depth of the keyway and protruding upwards perpendicularly from the base of the case is the ward plate. Attached to this ward plate and protruding out perpendicular to it and horizontal to the keyway are the wards. When the key is dragging the restrictor across the wards and ward pick preventors travel through the cutouts in the key. If the key doesn't have the correct cutouts it won't be able to drag the restrictor across as it will hit the wards and ward pick preventors.

To open the lock the magnet guarding the keyway must first be removed. This is removed by the two magnets which are held on the key's bow. The key is then inserted so that it engages the indent(the indent on the bottom of the restrictor etc not the indents for the retainers or the ones that engage the side of the shackle that becomes independent) and raises the pins. The key is pulled in the same direction as the ward plate is on. This means the indents in the restrictor are no longer engaging the indents in the side of the shackle that becomes independent of the case when the lock is opened. This side of the shackle can now be pulled up.

In its mortise and rim form there are four variations.

1) The restrictor could be the actual bolt and engage the restrictor 2) The restrictor can have protrusions on top of it so that they can make contact with protrusions connected to the bolt. The bolt can be alligned behind,above or in front of the restrictor. As the restrictor moves either backwards or forwards the protrusions on the restrictor strike those on the bolt and it moves in conjunction with it.

3) The mortise and rim setup don't require a distance creator.

R Li 1 4) The restrictor doesn't require indents as it is either engaging the strike or moving the bolt into the strike.

7 Operation 1) The user obtains the appropriate key and removes the magnets from the bow.

2)He places the magnets near the magnetically attracted device guarding the keyway. The magnetically attracted device guarding the keyway is attracted to these and access to the keyhole is given.

3) He inserts the blade as far right or left of the keyhole as possible so that that it engages the key indent in the bottom of the retrictor.

internally a number of things occur: a The key engages the restrictor indent b The pin raisers travel behind and in front of the restrictor,through the ward plate raising the pins.(They contact the part of the pin protruding in front of the pin jammer called the tab.) 4) The user then drags the key in the appropriate direction, horizontal relative to the keyway as far as it can go.

internally a number of things occur: a The restrictor is dragged in whatever direction horizontally relative to the keyway so that it is no longer engaging the strike or the bolt it moves is no longer engaging the strike(rim or mortise setup)or the side of the shackle that becomes independent when the mechanism is opened.

b The restrictor is retracted so the distance creator is no longer engaging the shackle c As the pin raisers move in conjunction with the key holding up the pins they encounter the pin jammers. They won't hit these if they are shaped properly d The ward and ward pick preventors pass through the cutouts in the key.

e The spring guard moves into the cutout in the restrictor and the spring is compressed against r(Ct- F(.LF plate.. The shackle can now be pulled out or the door opened.

If someone attempted to pull up the shackle in a closed position they would be unable to as when the shackle is pulled up its indents mesh with those of the side of the shackle that become independent when the lock is opened.. The restrictor can't move up due to the retainers.

37)restrictor indent(the indent running along the front and back of the restrict6r the retainers engage.) parts deascription: case-this contains the locking mechanism. For a padlock the necessary holes would need to be drilled for the shackle. It is essential to allow enough room for the movement of the restrictor when it is moved either back or forwards. The case differs from ordinary ones In that there are case exstensions and magnetic charges on the bottom of the case.

case exstensions-These are merely peices of metal extending on all four sides of the base of the lock. Their purpose is to surround the magnetically attracted device so tightly as to allow no pick between it and the magnetically attracted device.

\jiRT 0 magnetically attracted device-covers the base of the lock and is held on by the magnetic charges surrounding the keyhole. It should fit very tightly surrounded by the case exstensions and its length should depend on that of that of the base of the lock. It is removed by magnets attached to the keys bow and thus the combined force of the magnets that remove it should be stronger than that on the base of the lock.

magnetically charged case-this charge covers the entire base of the lock around the keyhole and is what holds what holds the magnetically attracted device on.

keyhole-this is where the key enters. Its width is that required for the width of the key and the distance the restrictor needs to be retracted for the mechanism to open. Its depth should be slightly deeper than that which the key and pin raisers take up. There should be a bit of space between the sides of the case and the pin raisers.

side of shackle that does become independent of the case when the lock is opened-it should cover a height of 2/3 of the case. The depth of its indents should respond to the size of the indents in the restrictor. The height it protrudes down in the case should be less than the side that doesn't become independent. Should be in line with the stopper.

shackle stopper-this is attached to the case under the side of the skackle that does become independent of the case when the lock is opened. It stops the shackle from been pushed down any further than it should so that its indents allign up with those of the restrictor=wouldn't be necessary in a rim and mortise setup.

projections-these are merly devices protruding from the side of the shackle that doesn't become independent of the case. The shackle can move no more when it hits the top of the case.

side of shackle that doesn't become independent of case-the height it protrudes down the case should be more than that of the side that becomes independent. It should be positioned so the restictors don't rub against the side of the case.

rctmc-i-o( plate-this is a rectangular plate protruding perpendicularly from the top of the case. It can move any distance down the height of the case but shouldn't interfere with the restrictor's movement.

restrictor-this is the device that is forced by the pressure of the spring so that its indents engage indents in the shackle, it engages the strike or moves the bolt into the strike. As it moves back against the spring exerting a force on it its slides along the restrictors and the spring guard moves into its cutout. From bottom to top of the restrictor there is the retainer indents, pin chamber and the ward plates. The key indent is on the bottom. The restrictor should be positioned in the case so that there is ample room for its movement. Its cutouts should be in line with the spring guard and its indents in line with those of the shackle.

spring guard-this is merely a rectangular projection connected to the4 eApted-iplate protruding of it perpendicularly and horizontally relative to the keyhole. Its surrounds the entire spring and prevents picks from getting to it. When the restrictor is retracted it enters the cutout in the back of it.

Restrictor spring- This is attached to the restrictor plate and is surrounded by the spring guard which it rests on. It is forcing the restrictor into the shackle or strike. The pressure it exerts on the restrictor in a horizontal fashion relative to the keyhole should be very strong.

Retainers- These protrude from the front and back of the case perpendicularly and horizontal relative to the keyhole. These are merely rectangular protrusions that engage indents on the front and back of the restrictor. The retainer's indents should slide along these. They should be positioned above the ward plate and pin chamber and shouldn't interfere with these.

Restrictor indent This is a indent on the end of the restrictor that engages the indent in the side of the shackle that becomes independent of the case I I restrictor wards- These are attached to the restrictor on the front and back running perpendicular to the restrictor and horizontal relative to the keyhole. It is positioned under the pin chamber and retainer. It moveas in conjunction with with the restrictor and shouldn't touch the back or front of the case. There is a hole in it that the pin raiser travels through to raise the pin. The hole should be positioned below the pin tab.

Pin raising hole-is a hole on the ward beneath the pin tab. The pin raisers travel through it Pick inhibitor This device is on the opposite side of the keyhole to the ward plate. It protrudes Sperpendicularly from the base of the case so its height doesn't matter.

Hardened steel and beryllium copper plates. These plates are on every side of the I case(front,back,right side,left side,top,bottom) when I have referred to parts been attached to the back of the case they are in reality attached to the hardened steel and beryllium copper plates.

distance creator-This protrudes from the top of the case in a L shaped fashion. This protrudes through hole in the shackle that becomes independent of the case when he lock is openend.

retainer brackets- These are attached to the front and back of the case below and above the retainers. They prevent the retainers from moving up or down.

strike-This is found on the door and is the object the restrictor engages in the mortise or rim setup=doesn't apply to the padlock setup distance creator hole-This is the hole the distance creator goes through. It is found on the side of the shackle that becomes independent of the case when the lock is opened. It should be in line with the distance creator.

ward pick preventor- ward pick preventor- This devices are attached to the side of the minor wards and protrude to the front and back of the case. They should protrude most of the length of the front and back of the case. They prevent picks from pulling the restrictor back against the spring by going in front or behind the plate.

side of shackle that doesn't become independent of the case when the lock is opened-This protrudes further down the case than the side that does become independent does and is prevented from becoming independent of the case by retainers.

retainer indents-these are indents on the front and back of the retrictor which the retainers engage. When the retrictor is retracted its indents slide along the retainers.

key-will be discussed later pin raising protrusions- protrude from the key and raise the pins.

13 pin jammer: There is one connected to the front and back of the case. It should be positioned near the pin so that the pin will hit the bottom step if the restrictor is moved a short distance without the pin been raised. The pin jammer is a staircase formation.

Why is the pin jammer shaped as such? a If the pin jammer was merely a rectangular protrusion jutting out in front of the pin a criminal would merely raise the pins once which would result in them sitting on top of the rsetrictor. All the criminal would have to do is to work out how to retract the restrictor and the pins would merely slide across the top of the jammers making them useless. With this shape it would only slide a short distance before it will hit the base of a step.

b The shape is also as such as to make it so that the user doesn't have to slide the key back along with the restrictor to shut the mechanism. The restrictor is forced forward by the spring so the pin just drops from level to level.

ward plate: The ward plate is connected to the bottom of the case and is perpindicular to.the bottom of the case.

)ward plate,2)master ward,3)wards,4)ward pick preventers ward plate-this is the plate the wards are connected to. This plate is connected on the inside of the case to the side of the keyhole. It is perpendicular to the base of the lock. The depth it covers RA is less than that of the keyhole m ,master ward-these are wards that cover the hole depth of the plate. They are rectangular Srotrusions running perpendicular to the plate and horizontal to the keyway.

tL N;ards-these are the smaller wards and increase the number of key cominations 14 ward pick preventors-these are attached to the sides of the minor wards. The one on the back of the ward plate protrudes to the back of the case and the one on the front of the ward plate protrudes to the front of the case. They can only be attached to the side of the minor wards which is obvious when the key's interaction is seen with the ward plate. They should protrude along the majority of the length on the front and back of the case. They are there to prevent picks from taking a path in front or behind the ward plate.

refer to page 7 of drawrings pin chamber r)chamber,2)spring,3)pin,4)slider rectangle,5)tab 6)pin arms,7)retainers,8)pin chamber connector chamber-it is attached to the retrictor by the pin chamber connector and houses all the parts pin spring-this is the spring pushing the pin so that it will hit the jammer if it isn't raised up into the chamber pin-this is the device that hits the jammer if it isn't raised slider rectangle-this is a cutout on the left and right side of the chamber. The pin arms protrude through this and slide up and down it as the pin is lowered and raised.

tab-this is the part that is connected to the pin and is the part the pin raiser contacts when raising the pin. A small part of the pin protrudes in front of the jammer and this is the part positioned directly above the ward hole.

pin arms-these are attached to the pin arms and move up and down with it.

retainers-the retainers are small peices of metal on the inside and outside of the chamber(on the inside and outside of the slider rectangle)on the retainer arms pin chamber connector-this is on top of the pin chamber conneting it to the restrictor.

refer to page 2 of drawrings 16 In a locked position the pin is pushed down by the spring. If it isn't raised it will hit the pin jammer which will prevent the restrictor and pin chamber from moving.

The reason that the pin doesn't move violently to the left or right when it hits the pin jammer is that the pin retainers only allow it to slide a fraction of a mm.

The system in which I have been describing so far has 2 chambers(lon the front of the rectrictor and 1 behind The more chambers there are the harder it is to pick but it also means that the keyway has to be wider.

What happens if the lock is turned upside down? The pin spring has enough force to support the pin so that it will still hit the jammer.

If the lock is turned onto the side the pins won't be able to move due to the retainers.

The tab should be as small as possible in both width and length. The part that the pin raiser contacts should be positioned above the restrictor ward hole.

Both the ward and pin chamber are connected to the restrictor so that they move when it does.

When the user inserts the key the pin raiser on 1 side of the blade goes in front of the restrictor I: AC/ while the pin raiser on the other side of the restrictor goes behind the restrictor. As the pin chamber is dragged to the left with the restrictor the pin raiser goes to the left which means it ,i must be shaped correctly so as not to hit the pin raiser jammer. If it is incorrectly hits the pin chamber it will prevent the restrictor from been retracted.

17 bkde- 7)magnebow,2ts 3 )pin raisers,4)master ward cutout,5)ward cutouts, 6 )ward pick preventor cutout key: bow-this is the section the key is held by. It must be made from a magnetically attracted material. The magnets that remove the magnetically attracted device are attached to this. One on each side of the bow.

blade-It contains the cutouts the wards go through, its width and depth determine the size of the key indent on the bottom of the restrictor. It should be in in line with the key indent and the pin raisers are connected to it. (note:the pin raisers must be above the cutout for the the ward pick preventor on the side of the blade) pin raisers-these are attached to the blade on thent and back and must be shaped Properly so as not to hit the pin raiser jammer. t should be the correct height so as to contact the pin tab. It must be positioned above the ward pick preventor cutout master cutout-these are cutouts the master wards pass through.

cutouts-these are the cutouts the ordinary wards go throughward pick preventor cutout- this is the cutout the ward pick preventor goes through.

magnets-these are attached to the front and the bow and are used to remove the magnetically attracted device on the keyway 18 How does a locksmith make a emergency entrance To open the lock without the appropriate key the locksmith primarily has to drill through the case, retract the restrictor and drill the two pins off. There are 3 holes drilled. One to retract the restrictor and the others for the pins.

In different systems the ward plate will be at different heights and the chamber will be in different positions relative to the keyway. The reason that one key can't open the rest of the locks in the system is obvious if you look under the heading system, will be discussed later. In a system the position where the holes are required to be drilled are identical. The part of the hardened steel and beryllium copper plates alligned with these holes can be made from a softer material. The different systems can have different templates.

Emergency Entrance Procedure 1) Work out which system the lock is in. This can be marked on the inside of a case exstension so that the locksmith is at least required to remove the magnet.

2) Obtain a drill and penetrate the appropriate holes. It should penetrate at least 4mm into the restrictor and should drill the bottom of the pins off.

3) Insert a stiff peice of wire into the restrictor hole and retract it.

4) While holding it back raise the right side of the bolt Why doesn't thevitretracting the restrictor hit the wards? The whole is drilled in the front plate above the ward plate.

l w Repairs cpen the case and pull off the front and back plates, remove the spring guard which gives access to the restrictor. As the back and front plate are pulled off the retainers disengage the restrictor.

1) The lock may need lubrication so you would apply graphite to the restrictor indent 2) The restrictor spring may need to be removed and repaired.

The chambers may need to be repaired so it is essential they can be opened and removed from the restrictor.

case construction one weakness of the lock is that it isn't necessay for a pick to engage the key indent to retract it.

He could use picks to raise the pins and pull back with force on the picks which exerts force on the ward holes which pulls the restrictor back against the spring. The pick would have to be shaped in such a manner that when it is pulled back it won't hit the ward pick preventors or the pin raiserjammers. There could be a device shaped as to do this and so as to rule this Possibility out there has to be 1 feature in holding up the locks security.

Let us call the width the key covers when inserted the keystall width. The ward pick pieventor has to be as close as possible to the keystall width. The distance the restrictor shuld he retracted should be at least two 3 times the stall width or 3 times the width of the key. This means it isn't possible for 2 picks to raise the pins and push them back.

21 To retract the restrictor why can't he insert a pick and pull it back? If it is beneath the restrictor it will hit the wards. If he goes in front or behind the restrictor he willit the ward pick preventors Why can't a peice of1if4wire that bends to the wards shape be used? The pressure from the restrictor spring is too strong.

Why can't a pick with the same diametre as the ward restrictor hole be used? It will strike the raising jammers.

22 What happens if a piece of wire such as a rigid paperclip or hairpin is used? It would be difficult to make the spring pressure too great to raise.

If he manages to get these up there as soon as any of these devices hit the pin jammer the top half of it fling violently to the left. This means it is no longer engaging the pin raising tab and it is pushed downwards again due to the spring pressure. This is why it is essential to make the pin raising tab as small as possible. These devices can only really be moved a little bit to the left before they hit pin raisingjammers. If the intruder was picking the lock by himself he would have to be very dexteros to raise to raise the two pins simutaneously while retracting the restrictor.

Hard attacks The most obvious is drilling which has been covered by the hardened steel and beryllium copper plates Hammer attacks- It would be impossible to knock the restrictor out due to the retainers 0 23 page 1 top left-view from the right of the mechanism closed-refer to page 8 top right -view from the right of the mechanism open-rp8 bottom-front view of the mechanism closed-rp8 page2 top-view from front of mechanism open-rp8 bottom left-view of pin bottom right-key-rpl 7 page3 all parts of mechanism shown-rp8 page 4 3d of mechanism closed-rp8 page 3d of mechanism when the key is inserted-rp8 page 6 3d of mechanism open-rp8 page 7 top left-ward plate, top right-ward plate-rpl3andl4 middle-base view of the restrictor-rp8 bottom-view of the base of the lock-rp8 page 3 top-mortise or rim setup where the restrictor is the bolt engaging the strike-rp8 bo.tcrm-setup where the restrictor is forcing the bolt into the strike.-rp8 :kinr the spring?
