This invention relates to selection apparatus of addressing and other similar printing machines, of the kind in which printing plates fed into the machine control,'by the action of indicators such asriders, tabs, projections, depressions, or'recesses located in or on the printing plates'or their holders, certain processes of the machine, such as the application or vwithdrawal of the printing pressure. Groups of switches adjusted on'a selector in such apparatus have had only an individual effector action, that is to: say, all the printing plates having indicators which corresponded with individual switches of the group were used for control purposes. As the indicators of a printing plate do notvall necessarily correspond with one a'djusted group of switches, the difiiculty arises that they can'- not be uscdfor a group action, so as to augment'or manifold the adjustments and adapt them to diflerent :office organizations. An object of the present invention is to overcome this ditliculty. a

The salient objects of this invention are to provide a selection apparatus comprising a switching-over device that may be readily positioned for so-called group actionor for individual action; to provide a switching de-' vice comprising stationary and movable contacts that maybe actuated by indicators on the printing devices; to provide a selector wherein the electrical connections will be so arranged that passage of the current therethrough may be regulated in order that only desired circuits may be closed; and to provide a selector having relays therein so arranged in the circuits that fluttering thereof will be prevented, I i o In the accompanying drawing the invention is schematically illustrated and the electrical connections are diagrammatically shown; I a

In order that the invention may be clearly understood and readily carried into effect, the same will nowbe described morefully with reference to the accompany drawing wherein a plurality. of stationarycontacts 0 to o are shown as being carried by a block or blocks of insulating material 1, and arranged on these blocks in spaced relation with the stascribed in the Duncan patent No. 1,481,860,

patented January 29, 1924,- and this feeding device sequentially moves the printing devices a through the guideways 3 first into the selecting position wherein the printing device a is shown and then into printing position wherein the printing device a is shown. Impressions are made from the printing device a" through the suitable ink ribbon R by a platen 5 carried by the-platen arm 6 including a bearing 7 pivotally'mounted on the frame 8 of themachine. The machine also includes a driving pulley 9 mounted on a shaft 10 and receiving power through a belt 11 from a. suitable source of power suchi as anelectric motor. On the shaft 10 is a crank arm 12 having alink 13 connected thereto which is pivotally'connected at 14 to a rocker 15 pivotally mounted on the frame 8 at 16. Pivotally mounted on the rocker 15 at 17 is a link 18 having a notch 19 therein, and a pin 20 ona portion of the platen arm 6 depending below the bearing 7 thereof is=disposed in the notch 19 to therebyconnect theplaten arm 6 to the link 18 and the rocker 15 so that" as the driving pulley 9 is operated a reciprocatory movement will be imparted to the platen 5 to therebyapply a'printing pressure. -As is well understood in the art,"the operation of the feeding device 4 and the platen 5 are in timed relation'relative to each other and the printing device is first moved through the selecting position before moving into printing position, and when in selecting position the selection apparatus determines whether or not the platen 5 is to be operated,'and this is brought about in the following manner: The indicatorspreviouslyreferred to are in the present instance tabs 22 and the device is, in the disclosed embodiment, arranged for group action, that is, tabs, such as 22, must be in the three positions indicated before the platen will be rendered operative. Detecting fingers 23' are pivotally mounted on a shaft 25 and are'disposed to be engaged by the tabs 22 on the printing device a 'in semaybe moved downwardlyinto' circuit closing position and retained therein, the plungers thereof including shoulders which en'- gage a suitable latchingdevice. When the plungers-of the switches e to e are moved downwardly-they close acircuit between the cooperating pairs of contacts that are respectively indicated by m to m and y to y", Conductors; t to. respectively interconnect the contacts k tolc and m to :0 The 7 contacts 3 to jI are each connected to aconsource of current i.

ductor 26 which is connected 'to one terminal of the winding offa controllingrelay-g, a conductor 27 being connected to the other .terminalof this winding and to a conductor 29 which is connected to one terminalof a A conductor 28'is connected tov the other terminal of this source of current. The conductor 29' is also connected to one terminal of the winding of the operating relay 7a,: the otherv end of this winding being connected through a conductor 30 to the armature m of the relay g, which armature is movable between contacts p and n and whichis normally urged into engagement with the contact p by the spring '31. The contact 12 is connectedrthrough a conductor-32 to the terminal 33 of the switching-over. device, generally indicated by f. The contactn is connected by. a conductor 35 to the contact 36 of the switching-over de-' vice f. The conductor 28 is connected to the switch blade 37 of the switching-over device in The contact;-'3 6 of the switchingover device f'is connected through a'conductore, to each of the'contacts 0 to 0 while the contact 33 of the switching-over device is connected through the conductor r to each of the contacts 6 tob"; lvhentthe device is to be arranged ,forpgroup action, the switch blade 37 is engaged with the contact 33. A circuit, is therefore established from." the sourceof currentz'Jthrough the conductor 28, switch blade 37, contact 33,- 'conductor 1',

to the various contacts I) to I), through the of the tabs 22 on the printing device a in selecting position. Therefore, the dircuit will be established through the plungers of the switches from the contacts 00 m and m to the" contacts 3 'f and 3 and thence through the conductor 26 to one end of the winding of the relay 9 and through" the conductor 27 to the conductor 29 and thence to the-other. terminal of the sourceof current i. This energizes the controlling relay 9 and the armature m is attracted thereby and contacts with the contact n which is connected to the contact 36 on the switching-over device f and which is therefore isolated from the circuit. However, when a printing'device havingtabs positioned as the tabs 22, which correspond to the closed'ones of the switches e to 6 moves into printing position the detecting fingers 23 are moved, and in this instance the contacts A, 76 and k willbe disengaged from the contacts 6 b and b and therefore the circuit to the windingofthe relay 9 will be broken, the circuit between the contacts b and k and b? and k4 being opened by reason ofthe disposition of the switches e and e. The de-energizing of the 'controlling relay 9-; permits the spring 31 to move the armature m into engagement with the contact p and therefore an electric circuitwill be closed as follows The, current will flow from one terminal of. the source 11 through the conductor 28, switch blade 37 to contact 33, through conductor 32, contact 1), armature m, conductor 30, winding of the relay it, through the conductor 29 to the other terminal of the source 2', and therefore the operating relay b will be energized to thus attract the armature 4O which. is pivotally mounted at 41 on the frame Sand therefore the nose 42 on this armature will be retracted from engagement with the nose 43 on the dog 44 fixed on the shaft 45, which extends below the guideways 3, and on the other end of the shaft 45 is a dog 46 having a roller 47 thereon adapted to be engagedby the block-48 on the link v18. Prior to the time the armature40 was attracted the nose 42 engaged the nose 43 and therefore positioned the dog Hand thus the'shaft' 45, dog 46 and roller 47 'so that the :block48 engaged said roller and held'the link 18 in the positionil- I lustrated whereby the notch 19 was disengaged from the pin 20, and it is therefore .nianifest that the platen arm 6'was not con nected to the rocker 15 and therefore was not operating. But, when the armature 4O meal is attracted and the noses are disengaged, the spring 49 moves the dog'44 and the arts carried thereby so thatthe roller 47 isengages the block 48 and therefore the notch 19 may engage the pin 20, and therefore the link 18 will motivate the platen arm 6 to apply printing pressure through the'platen 5,

' The block 48 will move beyond the position of the roller 47 when the platen moves in the performance of a printing operation, and on the return stroke the block w1ll engage the roller and therefore the shaft and dog 44,

will be moved and the projection on the dog 44 will engage the latch 51 that is urged into engaging position by the spring '52, and

when the parts are so positioned the nose 43 will have again moved below the nose 42 and the latch 51 will hold the parts for a short time during the changing of the printing devices. If a printing device similar to the printing device a moves into selecting position, the circuit to the operating relay It will;

again be closed o and the armature 40 will again be attracted and therefore the spring 49 will again move the parts, as above de-- scribed, to bring about interengagement of the pin 20 and the notch 19, the latch. 51*

serving to hold the parts during the timethe circuit is broken which occurs when the printing devices are changing. If, however,

, the printing device which moves into selecting positions does not have tabs positionedas, illustrated, the circuit to the controlling relay g will be closed and the circuit to the relay 7:. will be opened, and therefore the platen will not operate by reason of the engagement of the nose on the armature 40 with the nose 43 on the dog 44.

When the device is to be arranged for individual operation one or more of the.

switches e is closed depending upon the selection desired, and the switch blade 37 is engaged with the contact. 36 and a circuit as follows is set up: Current flows from the source-i through the conductor 28, switch blade 37, contact 36, conductor 8 to the various contacts 0 to o. A circuit will not be established however until the detecting fingers. engage tabs which cause the movable contacts to k to move, andwhen a contact, or contacts 70 to k is moved intoengagement with a contact or contacts 0 to 0 which are connected through conductors t to t to contacts :0 V to :0 they are connected'with contacts 3 to y" of the closed switches. Therefore, current will flow from the engaged of k the contacts y to 11 through the conductor but when relay 9 is'ener 'zed, asjiust set forth,- a circuit is closed. to t 'ef'operating relay in the following manner; from the 7 source i through the conductor: 29, relay h,

conductor 30,4armat1irem, contact-n, for the armature m will have been attracted by the relay 9 and will be engagingthis contact,

and from this point the, circuit is established through conductor 35 to contact 36, "switch blade 37 and conductor 28 to the other ter- ,minal of the'source 'z', and it is therefore apparent that the operation thedog46v and roller, 47 will. be performed in a manner previously, described to control the operation of the platen 3!), for the action of the armature 40 in this instance will-be. the same as I, that Previously described.

. ;The selector mechanism isarranged in inoperative position by disposing the switch blade 37 in the intermediate position ill'us .i trated. NVhen the controlling relay g is d'eenergized the spring 31 holds the armature m in. engagement with v the =-contact Thus when the switch blade 37is first moved into engagement with the contact 33 it might be .gpossible that the operating relay 1h wouldbe energized 'priorto' the time the relay .9 isenergized to attract the "armature m and .dis-

engage it from the contact p, foritis apparent that'the contact .pin the"conductor 32, againstw hich thearmature m will have been resting priorto energizingof the relay g, is

connected to the contact 33vand current therefor wouldfbe supplied tolthe relayoh. This would cause a fluttering of the operating relay it which might result in operation there- 1 of. a This is prevented however by providing [much more resistance in the operating relay Lhthan in the .controlling relay g, and dueto the high resistance in the relay h current'will not flowtherethrough prior to the time the. relay g is ener ized and in this manner fluttering of the re ay h is, prevented. Moreover any back flow or leakage in the circuit will notbe detrimental to the proper operation of the.

device by-reason of the difference in resistance between the relays g and h.

It is apparent from the foregoing description that I have provided a selector mechanism which may be easily arranged to either bring about a group selection or individual selection as may be desired, and that this may be readily controlled by a switching-over device that may be shifted into difierent positions that may be used to bring about different types of operation.
