Definitions
- each tumbler there is an auxiliary magnet fixed on the lock casing, and so arranged that each constantly attracts its related tumbler to bring and hold it in locking position when the key is withdrawn. At all times, each tumbler is under the attraction of its related auxiliary magnet, regardless of the direction and line of movement of the tumbler. Contact of the tumbler with its associated fixed companion magnet, is avoided by a nonmagnetizable media between them. Except for the magnets, the lock structure is of nonmagnetizable material.
- the strength of the auxiliary magnet is sufficient to maintain the tumbler in locking position regardless of the direction of movement of the tumbler, and the strength of the magnetic key insert is sufficient to shift the tumbler into unlocking position against the action of the auxiliary magnet regardless of the line of movement of the tumbler.
- the magnets are so positioned that all action on the tumbler is in attraction.
- the present invention relates to novel and improved magnetic lock constructions and the keys therefor, and more particularly to the type in which all magnetic action is by attraction.
- Locks of this class have heretofore replied on gravity action to return the tumblers to locking position, upon the withdrawal of the key. If a burglar could shift the lock a half turn, and such is known to have been done with cylinder locks, should the lock be of this magnetic type, it would automatically open. Further, magnetic locks of the past, of this general class, could not be used for cabinets, chests, trunks and other movable box structures, because all you need do to have the lock open by itself, is to invert the lock by setting the object it is mounted on, upside down.
- This invention contemplates a lock construction which operates on the principal that when a magnetic insert in the shank of a key is properly positioned in a lock, it will pull a tumbler from locking position to open position, and that for the tumblers, the lock includes companion means acting by magnetic attraction which will pull the tumblers back to locking position when the key is removed. In such combination, gravity is not called upon to play any part in effecting tumbler movement.
- Another object thereof is to provide the lock with antipicking means.
- a further object of this invention is to provide a novel and improved magnetic lock structure of the character described and having the states attributes, which is simple in construction, reasonable in cost to manufacture, easy to assemble and efiicient in carrying out the functions for which it is designed.
- each tumbler is permanently magnetized.
- the key has permanently magnetized inserts, one for each tumbler respectively, and so arranged that upon insertion of the key into the lock, the tumble-rs are attracted thereby and moved into unlocking position.
- Fixed on the lock easing are auxiliary permanent magnets, one for each tumbler respectively, and so arranged that each constantly attracts its related tumbler to bring and hold it in looking position when the key is withdrawn. At all times, the tumbler is under the attraction of its related auxiliary magnet, regardless of the direction and line of movement of the tumbler. Contact of the tumbler with its associated fixed companion magnet, is avoided by a thin non-magnetizable element between them. Except for the magnets, the lock structure is of non-magnetizable material.
- the strength of the auxiliary magnet is suflicient to maintain the tumbler in locking position regardless of the direction of movement of the tumbler
- the strength of the magnet key insert is suflicient to shift the tumbler into unlocking position against the action of the auxiliary magnet regardless of the line of movement of the tumbler.
- One pick-proof provision is to have one or more auxiliary tumblers of magnetizable material maintained in unlocking position by a fixed permanent magnet; each auxil iary tumbler being at a location where the key presents no magnetic insert when the key is in the lock in proper position to bring the main tumblers into unlocking position.
- I show herein its adaptation in a cylinder lock construction, and include structure providing that the key can be withgrawn, only that thereupon, the device is in locked conition.
- FIG. 1 is an enlarged longitudinal view showing a cylininder lock embodying the teachings of this invention, and also its key. This view is shown in section taken at line 11 in FIG. 3. The key is shown entering the barrel. The main tumblers are in locking position. The auxiliary tumbler is in open position.
- FIG. 2 is a fragmentary view of the device as shown in FIG. 1, but here in FIG. 2, the key is shown fully inserted, and hence the main tumblers are in their moved position and the barrel is free to turn in the casing,
- FIG. 3 is a Section taken at line 33 in FIG. 1.
- FIG. 4 shows a front view of the lock, that is, looking onto the left end in FIG. 1.
- the key is shown partly turned from its initial position at full insertion.
- the barrel has turned with the key.
- FIG. 5 is a fragmentary perspective View which shows the front end portion of the barrel.
- FIG. 6 is a fragmentary section only of the casing, taken at line 66 in FIG. 4.
- FIG. 7 is a fragmentary section showing a modified construction to hold a tumbler out of contact with its auxiliary magnet.
- FIGS. 8-10 are fragmentary sections of modifications of FIG. 1; FIG. 10 being drawn to a reduced scale.
- the numeral indicates generally a locks cylinder or casing in which a barrel 16 is rotatably fitted, and as is well known, said barrel carries a suitable member 17 to shift the locks bolt not shown, upon rotation of said barrel within the casing.
- Said barrel and casing are of non-magnetic material and so is the body of the key 18 which is slidable into and out of the barrel.
- Each hole and its related socket are of like diameter, adapted to house a slidable permanently magnetized tumbler which is of a length greater than the distance it can enter into the hole, so such tumbler can be part in the socket and part in the related hole of the cavity.
- Those holes having a tumbler are closed by a permanent magnet as indicated at 20, so the tumbler is within a chamber.
- the key 18 has permanently magnetized inserts in the same spaced relation as the tumblers so that upon full insertion of the key into the barrel 16, one of such inserts is in axial alignment with one of the tumblers respectively.
- the holes containing the tumblers 20, 21 and 24 are in one row along the casing, with the holes 19 and 25. If desired, tumblers may be provided in the holes 19 and 25, and such, together with the tumblers 20, 21 and 24, may constitute the entire locking means. Of course, wherever there is a tumbler, there is a companion auxiliary fixed magnet, as for instance the pair 20, 20'. However, in the illustrated embodiment, I have provided a second series of holes in another row along the casing 15, with companion sockets in the barrel 16, such sockets being indicated by the respective numerals 26-30, and have provided the tumblers 31 and 32 to be in staggered relation with the tumblers 20, 21 and 24, thereby leaving half the holes empty.
- the magnetic components of this lock shall comprise sets of three magnet pieces each, namely a tumbler, an auxiliary fixed magnet on the casing and a magnetic insert in the key.
- the tumbler is under the action of at traction by its related auxiliary magnet, and when the key is fully inserted into the barrel, the tumbler is under the action of attraction by its related key insert;
- auxiliary magnet Of prime importance is that no contact shall occur between the auxiliary magnet and the tumbler, meaning that constantly between them, only non-magnetizable material shall be present.
- One way to accomplish this is to have a thin piece of copper 44, fixed at the end of the auxiliary magnet facing the tumbler, or it may be on the tumbler end which faces the auxiliary magnet.
- Another way to have such non-magnetic material between them is to have an air gap 45, which is maintained by providing a stop shoulder 46 for a shoulder 47 on the tumbler 48, a construction shown in FIG. 7.
- the tumbler 20 is related with the auxiliary magnet 20' and the magnetic key insert 20".
- the tumbler 21 is related with the auxiliary magnet 21' and the magnetic key insert 21".
- the tumbler 24 is related with the auxiliary magnet 24' and the magnetic key insert 24".
- the tumbler 31 is related with the auxiliary magnet 31' and the magnetic key insert 31".
- the tumbler 32 is related with an auxiliary magnet not shown, and with the magnetic key insert 32".
- the casing 15, a bit behind front end, is provided with an internal annular channel 35, along which the tip end portion of pin part 33 rides fitted therein, upon turning the key 18, after such key is fully inserted into the barrel.
- the barrel 16 has a short keyway 37 enterable at the front end by the pin part 33", and of a depth, just to admit it.
- the barrel has a notch 36 enterable at the front end.
- the length of said keyway 37 and the depth of said notch 36 are such that when the key is fully entered in the barrel, the distal end of the pin part 33' will enter the channel 35 when the key is then turned.
- Said notch 36 and keyway 37 are of course so positioned that they receive the pin 33 when the key is fully inserted in the barrel.
- the notch 36' in the casing is so positioned that it registers with the notch 36 when the tumblers are in locking position.
- the keyhole offered by the notches 36, 36' and the keyway 37 shall admit the pin 33 when the latter is vertical, in order to conform with ordinary lock practice to have the key in the vertical plane for insertion. It is evident that the key can be inserted only in one way, since the keyway 37 will not admit the pin part 33, but can only admit the pin part 33", which is much shorter than 33.
- the device may be provided with an auxiliary tumbler 40 of magnetizable material as soft iron, wholly within the hole 41 in the casing and there maintained by the permanent magnet 42 fixed in such hole.
- the barrel has a socket 43 into which part of said auxiliary tumbler 40 would be withdrawn into by such overpowering magnetic field and thus maintain the device in locked condition; said socket 43 and the hole 41, being in alignment when the device is in locked condition of FIG. 2.
- the forward end of the barrel 16 is of reduced diameter and the cylinder 15 is bored and counterbored, suiting the barrel to fit therein for rotation; the assembly of said casing and barrel being effected by a strong split retaining ring as shown at 49.
- the tumblers In the scheme of structure herein taught, the tumblers must be drawn into unlocking position by forces of attraction furnished by the permanently magnetized key inserts, and they must be drawn into locking position by some auxiliary means to which they are attracted when the key is out of the lock.
- auxiliary means are the fixed permanent magnets 20, 21' and the remainder of such series. It is therefore evident that the key must have its magnetic inserts, and that when the auxiliary 50 is a permanent magnet, its related tumbler 50 may be of soft iron and unmagnetized, or that when the tumbler 51 is a permanent magnet, its auxiliary 51' may be of soft iron and unmagnetized.
- all the auxiliaries may be offered by a soft iron sleeve 52 on the casing, which sleeve closes all the holes in the casing, and for the non-magnetizable separator, said sleeve may have a copper or brass lining 52.
- the force of attraction of the key insert upon a tumbler must be suflicient to move the tumbler into unlocking position against the force of attraction of the tumbler for its auxiliary, and the force of attraction of the tumbler for its auxiliary, must be sufiicient to shift the tumbler into locking position, when the key is out of the lock.
- the sleeve 52 is securely attached to be part of the casing, and is preferably exteriorally threaded as is empirical in this art.
- a spring-less magnetic lock device a first member, a second member movably mounted on the first member; said members being of non-magnetic material; the first member having a hole therethrough and the second member having a socket therein in alignment with said hole, a tumbler element longitudinally slidable and fitted in said hole and socket, and positioned part in said hole and part in said socket and being capable of being housed entirely in said socket, an auxiliary element positioned fixed on the first member, across said hole, a nonmagnetizable media in the hole extending only between the tumbler and the auxiliary elements; one of said elements being a permanent magnet and the other being of magnetiza-ble material, in combination with a key of nonmagnetic material having a permanently magnetized insert; said key when placed in a position so that the magnetic insert is in alignment with said tumbler element and acting to attract said tumbler element so the latter is moved entirely within said socket in the second member, the second member will thereby be released for movement in relation to the first member; the strength of the magnetized
- a magnetic lock device as defined in claim 1 including second means on said key and second member, which come into alignment upon placing the key so that its magnetic insert is in alignment with said tumbler element, and upon such positioning of the key and when said tumbler element is entirely within said socket in the second member, the key can be manipulated to move the second member in relation to the first member.
