`ABSTRACT
`[57]
`A key blank selector-dispenser comprises a drum hav-
`ing a central axis aperture and severalseries of radial
`cells for receiving magazines of key blanks and con-
`tained in respective radial planes of the cylinder. The
`drum is rotatable by an electric motor having an elec-
`tromagnetic brake. Key blank ejectors for each said
`series are provided in said aperture and are located in
`the same diametral plane of the drum.
`A control panel has a numberofslots for insertion of
`specimen keys equal to the numberofsaid cells. Means
`actuatable by insertion of a specimen key closes the
`motorcircuit to start the motor. A cam on eachseries of
`cells operates a limit contact when a cell having a de-
`sired blank comesinto the plane ofthe ejectors to effect
`stopping of the motor and actuation of the ejector cor-
`responding to the series selected.

`BRIEF DESCRIPTION OF THE DRAWINGS
`
`It is well-known that it is often necessary to repro-
`duce flat keys for numerous applications such as door
`keys, ignition keys for cars, keys for door locks, suit-
`cases or various items of furniture, and there are at
`present automatic machines which makeit possible very
`rapidly to reproduce profiles of specimen keys from
`blanks of suitable form. Indeed, the variousflat keys are
`distinguished from oneanothernotonly by their profile
`butalso by their length, their width and mainly by their
`cross-sectional form: the result is that the locksmith
`must have available a very large number of blanks of
`different types, from which he must find out the blank
`whichis likely to be suitable for reproducing a specific
`specimen key. In order to facilitate the search, it has
`already been proposed to provide dispensers compris-
`ing magazine containers each containing blanks of a
`type which corresponds to a modelof key of one maker
`(indeed, keys generally bear the name ofeither the car
`manufactures, or lock manufactures, and also a refer-

`this type, whether they comprise magazines in the form
`of flat juxtaposed boxes each of which has an ejector
`device, or a rotatable structure having radial cells in
`which the blanks are stacked and which are, by rotation
`of the drum aroundits axis, automatically positioned
`opposite an extractor or ejector, are extremely cumber-
`some and mechanically complicated, which makes it
`impossible to provide therein a numberofcells adequate
`to hold the majority of the types of blanks correspond-
`ing to the various existing model of keys, even those
`used most commonly in various applications.

`Therotatable drum structure shown in FIGS. 1 to 3
`consists of a vertical cylinder 1, which has a central
`axially extending aperture, and which is supported by a
`base plate 2; the drum structure is capable of being
`rotated by means of a geared electrical motor 3, the
`driven pinion 4 of which meshes with a gear wheel 5
`integral with cylinder 1 just above the said base plate.
`Anelectromagnetic brake 33 which makesit possible to
`block the motor 3 whenits supplyis cut off is associated
`to the shaft of this motor. The cylinder 1 is formed by an
`assembly comprising a plurality of superposed rings, for
`example eight in number, suchas rings 11, 12, 13, 14, 15,

`rod 10 ofsufficient length to be engaged in the holes 9
`ofall the blanks 7 contained in the magazine, except for
`the lowest one whichrests directly on the bottom of the
`correspondingcell. A spring 19 is engaged over the rod
`10 pushing all these blanks downwardly so that after the
`blank occupying the lowest position has been ejected by
`means which will be described hereinafter, the follow-
`ing blank will take its place.
`On the underside of each ofthe rings 11 to 18 there is
`a cam such as 22, each cam being capable of actuating
`the nose 23 of the movable contact ofa limit switch 24
`corresponding to a vertical row of cells. The switches
`24 are mounted on a central fixed support disposed in
`the central aperture of the drum structure, each ofthese
`switches is operated by its associated cam in orderin-
`stantly to stop the motor driving the drum 1 when,
`during rotation of the drum, the vertical row ofcells
`containing the selected cell is brough in the diametral
`plane containing the ejector means which bring about
`ejection of the blank onto one of the plates forming
`inclined surfaces 251), 252, 2513. .
`. 251g directing the
`ejected blank to a receptacle 26 (FIG.1).
`It is to be understood that the cams and/or their
`associated limit switches are angularly shifted with
`respect to each other to be able to stop the drum struc-
`ture with a selected vertical row ofcells in front of the
`ejectors. Thus,
`the limit switches may be vertically
`aligned and the cams angularly shifted with respect to
`each other for an angle which correspondsto the angu-
`larly distance between two adjacent cells lying in a
`same horizontal plane. But a reverse arrangement may
`also be adopted.
`Mounted on the centralfixed support disposed in the
`central aperture of the cylinder structure,
`there are
`ejector means, one per superposed levels or series of
`cells uniformly distributed around the axis of the drum,
`each comprising an electromagnet 27 (FIGS.1 to 3)
`which is energized at the moment whentheselected cell
`stops in the vertical plane in which all the ejector elec-
`tromagnets are located, in front of the delivery plates
`25. Each of the electromagnets comprises a movable
`member 28 whichis attracted when the electromagnet
`is energized and connected by a very short cable 29 to
`a return device mounted on the fixed support and com-
`prising a small pulley 30 which this cable causes to turn
`and a larger pulley 31 on which is wounda longercable
`34 attached to a steel tongue 32 guided in a swallowtail
`slide and penetrating the cell which has stopped oppo-
`site the electromagnet in order to eject therefrom the
`blank 7 resting on the bottom ofthe cell and which is
`notretained bythe rod 9 of the corresponding magazine
`6. A return spring restores the tongue 32 toits initial
`position after ejection of the blank. By virtue of this
`return, the stroke of the tongueis longer than that of the
`armature of the electromagnet which makesit possible
`to reduce the bulk of the latter and at the same time to
`achieve a shorter operating time.It will be seen herein-
`after that in order to obtain a very rapid operation of the
`ejector electromagnets which impart a very abrupt
`movementto the ejector tongue 32, the ejector electro-
`magnet is energized by a brief high intensity pulse pro-
`duced by the discharge of a previously charged capaci-
`tor.
`The principle of selection of the cell containing the
`blanks corresponding to a specimen key which is to be
`reproduced will now be explained.
`Asillustrated in the simplified diagram in FIG. 4,
`there is associated to the dispenser a control panel not

`which panel comprises a number of template members
`35 corresponding to the numberofcells per level of the
`structure drum,
`in other words 60 in the example
`chosen. Disposed in each plate 35 are slots equal in
`numberto that ofthe stages of the drum,in other words
`eight in the example chosen, the slots 36, 36’, 36” on
`eachplate 35 having in cross-section a form correspond-
`ing respectively to that of the blanks contained in the
`eight cells which are in vertical alignment that is dis-
`posed along the same generatrix of the drum. The tem-
`plate members are made ofan electrical conducting
`material, and introduction of the specimen key 40 into
`one of the slots has the effect of making an electrical
`connection between this plate and one of the terminals
`37, 37’, 37" .
`.
`. disposed behind the plate and respec-
`tively connected by eight horizontal conductors38, 38’,
`of which only three are shownin FIG.4, to eight verti-
`cal conductors, 39, 39’, 39”... of which onlythree are
`shown.
`The conductors 39, 39’, 39”... are respectively con-
`nected to the windingsofeightlevel or stage relays R
`11, R 12, R 13... which are mounted in parallel on the
`supply circuit. The supplycircuit is thus closed by in-
`sertion of the specimen key 40 into the template and
`monitored furthermore by the limit switch 24, which is
`normally closed, on the ring 12 of the stage in whichis
`contained the cell containing the blanks corresponding
`to the slot 36’ into which the key 40 has been inserted.
`Mountedin the circuit which is thus monitored by the
`specimen key and the limit switch 24 is a push button
`switch 41 controlling operation of the motor via the
`winding of the relay R 19 mounted in series with the
`armatures r 11, r 12, r 13... of the stage relays R11 to
`R18. Other armatures r’11, 112, r'13. . . of the stage
`relays are mounted respectively in series with the ejec-
`tor electromagnets 2711, 2712... disposed in the corre-
`sponding stages 11 to 18.
`The dispenser according to the simplified diagram
`functions as follows:
`Insertion of the specimen key 40 into the slot 36’
`prepares the supply circuit of relay R12 of the corre-
`sponding level ofcells, which circuit is completed by
`manually pushing push-button 41in its operating posi-
`tion, thus causing energization of the motor 3 with the
`result that the drum 1 is rotated aboutits axis. When the
`ring 12 arrives in the position in which the vertical row
`of cells including the cell containing the blanks corre-
`sponding to the specimen key 40 is in front ofthe verti-
`cal row ofejectors, the cam 22 associated to the ring 12
`effects opening of the limit switch 34. The relay R12 is
`de-energized and its armature ri2 opens and causes
`de-energizing of the relay 19 which cuts the supply to
`the motor so that the drum stopsin the selected angular
`position the brake 33 blocking the rotor of motor 3. At
`the same time, the armature r’'12 closes the circuit of
`electromagnet 27)2 of the correspondinglevel or super-
`posed series of cells and actuates the ejector so that a
`blank corresponding to the specimen key 40 is passed
`into the receptacle 26.
`FIG. 5 shows the complete wiring diagram of the
`dispenser comprising 60 templates 35; to 35¢0 disposed,
`in order to reduce the overall height of the control
`panel,
`in six columns each containing templates and
`each plate, like the plate 35 in the diagram in FIG.4,
`offering eight slots corresponding to eight vertically
`aligned cells of the superposedseriesof cells.
