To all whom it may concern."

Be it known that I, FRANCIS H. RICH- ARDS, a citizen of the United States, residingA which the following is a specification.

lhis invention pertains to the relationship and organization of various coperative mechanisms and mechanical .devices designed to effect the selective transfer and positive location of any one of a series of members or i1levices-such, for instance, as typographie impressors-to and at a given or fixed point, such members, in general, being disposed normally in various positions with respect to such given point.

A mechanical movement embodying the present improvements will comprise, ordinarily, a support or carrier, capable of angular adjustment, with which support there is combined mechanism for shifting said member to the proper angular position to bring the selector'l ldeviceinto alinement with the fixed point. In cooperative relation with suoli support and thc selective devices thereon there will be, ordinarily, suitable* and proper mechanism whereby the selected device may be shifted axially of the support, these two movements, that is, rthe adjustment through a proper-and controllable angle, and the axial movement relatively vto the support will, as this mechanical movement is organized, be performed consecutively, thatjs, the angular adjustment will be completed before. the axial shifting of the impressor or other device is begun. Although tlns supportus capable, as aforesaid, of a movement aboutan'axis, I do not deem 1t essential that this movement shall bc the only oneY of which it.is capable, since the or- `'ganization may be such that there may be imparted toit a compound.movement, thatl 1s, a rbodily movement-of the member along a predetermined path, in addition to the movement which it has about vits own axis.

Various means may be employed for effecting the rotary and longitudinal orv axial adjustment of the series of impressors'lor other devices, the organization and construction illustrated in the presentg drawings being one. of simple character, and it not being contemplated by such illustration to restrict or confine'the application of the present mechanical movement to embodiment I in such illustrated mechanisms and mechanical devices.

In these drawings, Figure 1 is mainly a. longitudinal section through a key-controlled mechanism embodying my present improvements. Fig. 2 is a similar view of the rotary member or support embraced in the mechanism, illustrating the same in a position in which it has been adjusted to an angular position such that the selected device has een brought into vertical alinement with the point at which it is to be ultimately located; and Fig. 3 is a plan view of the mechanism shown in Fig. `1.

Similar characters. of `reference designate corres ending parts inall'figures.

Altio'ugh I ilo/not propose limiting the application of/,the'present invention to embodiment in any particular form or construction ofmechanism, I have, for the purpose of illustration and for the sake of conveniently representing a construction for its practical application, shown the` same as embodied 1n a `key-operated mechanism, since such an apparatus or mechanism is particularly adapted for effecting the conultimately locating the selected device at the given or fixed point. Any suitable framework ;may be provided for supporting the operativf `warts and mechanisms, such framework constituting a portion of the -main framework of the machine to which the present mechanism may be applied, or constituting a sub-frame of such framework.

Referring to the 'construction illustrated in the drawings attached to the present'speciiication, the framework is therein designated in a general way by' B, it being in this inlstance provided With,supporting posts or evs Y r,The relation between the constituent submovements embraced in the present mechanical movement is such th at the particular device selected fromgamong the assemblage thereof and, occupyii'gvanormal position whichis, in general, out of botlthe vertical and horizontal planes in which `the xed 'point is located isone1 of consecutive motion in different directions. More specifically, the present mechanical movement is one whereby the seleetedldevice is rst moved into one of the planesy of said fixedl or` given point, and subsequently, after transfer 'trol of the various movements necessary 'for Lnto i that plane, the vdevice isl shifted in that plane 'in the direction of the fixed point and ultimately brought .to rest the'reat. InA

peint is one composed of separate and indiupon a member or support at least capfable.Y

and combined vidual movements, the second'of which is not begun until after the completion of the first'. l. prefer to niountthe selective devices of rotation about its axis, with such inc inber, in proper cooperative relation therewith, suitable mechanism, 'whereby a particular device chosen from the plurality thereof mounted upon such member, may -be brouglit'into the vertical plane of the given point (assuniiiig-the axis of the member to bedisposed vertically), and subsequently shifted relatively to. the rotary member until it reaches or is adjacent to the given point. `ln the present embodiment, the rotary'member or support, designated herein in a general way by C, vis-capable only of a movement of rotation, althoughthe present invention is not limited in its scope of application td a member capablc'only` lof rotation about its own axis.. For the convenient lmounting and impartation of angular or rotary movement to thismember C,

it may be mounted as shown, this mounting comprising, as illustrated in theA drawings, a shaft 2, which in this instance is disposed vertically, being mounted adjacent to its lewer end in a bearing 3 formed in the frame' B and at its upper end in a bearing 3 formed yin an overhanging bracket t fixedly secured to the upper portion of such frame. A'

shoulder 2 extending between the-'main portion of the shaft 2 and a reduced portion forming the journal thereof constitutes means for maintaining the shaftin Iits proper vertical position, vthis shoulder resting upon the upper surface of the bearing 3. The 'inein' ber Cv may be attached .to the shaft 2in any proper manner, in this case a key 2 rigidly connecting the two, and the member C rotating Withfthe shaft 2. It may be premised thaty the various devices which are capable of being located, se`

lectively, at the given or fixed point are disposed circumferentially of. the' member 0 and hence the rotary movement ofthe shaft will su'llice to bring these circumferentiallydisposed devices into the vertical plane of the given point, here designated by x, or substantially so. In order to permit the rotary member to be actuated through the separate angles requisite for aliningthe various devices upon their respective selection with the `point 0c, I have, in the embodiment illustinted, represented afriction device normall operative to continuouslyrotate the sha t and hence thc member C, but of such construction as to be capable of being rendered' inoperative when a selected device has asl su ined a position vertically below such point. As set forth, a driving-pulley 5 is loosely mounted upon the shaft 2 and 'driven conveniently by a belt, for instance, ,from a Vsuitable source of 'power (not shown). In order to connect this pulley 5 with the shaftQ, friction'washers 5', 5 on opposite sides of the hub of the pulley are shown, 'which frictionally engage'ivi th such hub and with proper opposing frict-ion surfaces. In the construction shown, the latter friction face for the upper washer 5f is'eonstituted by the face of a boss -6 extend-ing from the lower or base-plate of lower washer 5 is' formed by the' side face members being capable of being forced together 'more or .less snugly by means of a nut -8 engaging with the lower end of the for driving the shaft 2 when free so todo.

Referring now to the devices capable of selective location at the point ,lthese will, of course, depend upon the character' of the apparatus to which the movement is applied. They'are, in this case, represented in the nature of impression devices capable of operat- 'fixed point As before stated, thesedevices, designated in a general way by D, are disposed circumferentially of 'the rotary devices being normally out of alineinent with the point of the member C, as aforesaid, to bring a chosen selective device into aliiiement with (that is, as here organized, vertically below) the point it, said device is -so related tothe member C that it may be shifted axially thereof' and so brought into proper relation or juxtaposition with the point'.-

According toI the preferred embodiment of the present movement, each axially-disposed series of'devices D will be mounted upon a proper element capable of longitudinal movement relatively to the'ineinber C.

suitable slides, designated herein by 9, each of which slides is inountedin proper guideberC to move lengthwise thereof in order to Briefly stated,- there embraced in the vpresent mechanical movement an assem the frame B, while'tlie reaction face of the.

shaft 2. Means are thus providedfor ad-. justingor regulating 'the friction effective member C and also axially thereof, all of such4 Each of' such series may, therefore,- be disposed upon' 'ways iii the peripheraltportion of the mem' of a second washer 7 these several friction'v ingupon-material located at the given or-v Upon the angular movement l blageor series of selective devices disposedl both circumferentially-andaxiallv of a inembei, all of which are capable of rotary movement with thc=inember, and of axial inove ment relatively thereto. In this instance there are shown eight vslides 9 (see Fig. B), although manifestly this number may be less or I'point face of the guideway formed in the member C.

As a simple and convenient mea-ns for stopping the rotation of the shaft 2in such a position that the member C shall be brought to rest with the'- slide. 9 thereon carrying the seleetedfor chosen device D vertically below or inline' with the point'x, a key mechanism is illustrated embodying a series of levers controlling the setting of properly disposed sto s,

whereby a stop in roper eordinate re ation with the givenv ide 9 will, when set, effect the arrest of the shaft2 with the member C proper position, as aforesaid. I do not deem, however, a key mechanism of this character as necessary or essential to a practical or operative embodiment of the present movement, since the mechanism shown is chosen merely as typical of the conditions requisite for causing the cessationof the roj tary movement (a motion, it will be understood, not in itself essential to the invention) vof the shaft with the member C in the proper position, as already described. j

Referring to the particular embodiment set forth, a series of eight keys K are shown, each of which has a distinguished mark corresponding to that slide 9 upon the member or carrier C which, when the particular key is actuated, serves to sto the motion'of the membej` C with the shde in line with the Each key mechanism comprises a .rey K, as aforesaid, mounted at the upper end of a key-stem 7c, passing through an opening in the front portion of the frame B, and at" its low'er end pivotally connected with a proper key-lever 10 fulcrumed, in this case, intermediate its ends toy a post 10 erected upon a supporting-plate or sub-frame l1 extending from side to side of the main frame J3. Controllable from each key-lever 1() is a stop-pin 12 shifted, upon the actuation of the key connected to it, radially toward the axis of the shaft 2, but normally held in its retracted position by means of a spring 13 whose vtension serves to elevate the outer end of the lever 10, and hence raise the key-stem r attached thereto to its highest position. These stop-pins 12 are preferably risposed, to insufe their proper action, concentricall y about the axis of the shaft 2, they beingr in this instance mounted in o enings in an annular support 14 rigidly afixed to the main frame B. This support 14 has, in this construction, ears 14', 14 extending toward the Aside members of the main frame, and is affixed by screws thereto in order to hold the annular support 14 in proper relation to the shaft 2.

A simple means for connectingeach lever with its proper stop-pin 12is shown in the present drawings comprising an angle-lever 15 fulerurned intermediate its ends to the side pieces of' a bracket 16 depending. from the annular support 14v one of the arms of the angle-lever 15 being properly pivoted to its stop-pin, while the other thereof is connected bya link 17 with its operating lever 10. It is plain from this construction, that when a key K is depressed the inner end of the connected key-lever 1() is elevated, causing, through the connection described, the inward movement of the stop-pin 12 operative therefrom. It will be understood that as the stop-pins 12 are disposed concentricvally about the axis of the shaft 2, they will be disposed at various pointscircumferentially of the supporting ring 14; hence the various levers 10 for effecting their movement will, usually be of various shapes in order that the inner end of each lever may be brought into proper relation with the anglelever 15, controlling the movement of the stop-pin whose setting the particular lever is desivnedmo effect. These levers will also generally in some instances be bent in one direction or another, particularly as illustrated in Fig. 3, that their interference with other operative parts of the machine may be avoided. Coperative relation between the stop-'pins 12 and the shaft 2 exists in this case through the medium of an arm 18, the hub of which is rigidly affixed to the shaft 2 in such a position that the plane of movement of the arm corresponds to the plane in which the several pins 12 are disposed. As-

suming a pin 12 to have been projected inward by the operation of the key K effective for its actuation, the projected pin protrudcs into the path of the revolving stop-arm 18, and when this arm comes into contact with it the resistance opposing the motion of the shaft 2 is sullieient to overcome the friction exerted by the rotating drivingpulley through the .friction-washers 5, described, and hence the motion of the shaft 2 with its member C'will be arrested. ln this position, therefore, the slide 9 carrying the selected device l), which is related to the key Kidethe shaft 2 that the slide 9 in line 'with the j point. is shifted axiall)v with reference to i fore, shown at the side of the lever 23 an inive for positively and spendingr recess 19 formed in the lower end of 4of rotation of the s iaft 2,'

. lt should be. stated that means lWill'ordi-v narily be providedvfor maintaining'the several slides 9 in 'their normal positions relaf tively to the member or carrier C. Such means may consist of alocking device effect# eil'ectively lo cking the slides in their norma-l positions during the rotation of the shaft 2.

For causing` at the will of the operator it is connected to a reciprm-,atory slide-bar21 arranged to slide to and fro in brackets22, 22 projecting from the'r'ear .end oft the 'main frame B, and being operative from a lever 23 conveniently disposed at the side/of the inechanisinand externally of theframe B. 'Ihislever 23 is aillXed-to a rock-shaft 24 journaled in proper bearingsin'the side pieces of the main frai'n'e,' fromv which rockshaft ,extends an arm 25 carrying at its freefend a rollerl 25 upon which rests a lcollar-26 allixed to the reciprocatory rod 2l.- (lontact between the colla-rl 25S and the roller 25"is, inithis instance, nmi-itainedby a spring 27 'inserted between 22, and

The slide-shifter .20 may be backed by aV fixedsurfeee in order to l insure the positive and firm enga' ing in this case formed at' the bottom' of a guide formed in an `u right 29 erected upon the upperportion 'of tfie main frame B.

.Preferably the tooth 20 is of a length suflicient to project inward beyond the outer edge of the guideway in the member C, in which. the slide Q is located. Hence, when the tooth is shifted out of alinementwith the locking ringl 19 during the adjustment of a slide axially of the member C, the latter will be locked from rotarial movement until the slide. has again-been brought to itsnormal p0- sition and thel tooth 20 re-aliiied with the locking` ring*- 19.

.So far as tlieoperative relationship existing between the various elements of the pres- .ent mechanical movement is concerned, it is obviously immaterial Whether the point x, relatively to which the various selective devices are capable ofadji'istnient is a simple point' or mechanism capable ofutilizing the adjusted device for the purpose oi' impressing or otherwise treating; a surface located at such point:v I have, in the present case, dis# dosed means for supporting a strip or sheet of paper and moving the saine subsequent to the adjusti'nent of a device to-the fixed point m, hereby such device, when of suitable adapted to engage with any one of a series of notches 'ement ofits tooth 20 with the recess 19 in t e slide during the movement of the slidey in its guidevvays, this surface'bev the same in each of its sevforni, becomes leffective to make' an impression upon thepaper.'

l As herein set forth, a .roller-platen 30 is shown journaled in side supports 31 consti.

tilting portions .of a roclcframe,'-designatedI -in ageiieral way by shiftable towardaiui away from the member C. ln this case theframe 32 is lournaled in a bracket 32 extending from the 'main frame 32, so mounted as to bei B, and is provided with an .arm 34 and a re- 5, normally tending: to swin 3G. whereby the rock-'frame may be rocked t0- Ward-the inemberf and the platen 3() caused scribed, of the pre-:ent mechanical movement, operates substantially in the following' Inannerz---Upon the depression of a key against the resistance of its elevating spring 13, the inner end of the key-lever 10 connected to the key-stem of the actuated key rises, and through the connecting-link 1'? and j crank-lever l-effects theprotrusion of the connected stop-pin 12` into the path of movement of the stop-arm 18 extending from the shaft 2. Assuming this shaft to be in continuous rotation' from the driven pulley 5, the shaft 2 will be brought to rest upon the contact of the arm 1S with such projected stop-pin 12, and the .pulley 5 will run idlybetween the friction-disks 5', 5. 1n this position of theshaft 2 the slide 9 thereon which carries the device D coordinated with the actuated key K will have assumed a position in which it is in alinernent with the fixed point w, while the Itooth 20' of the shifter-bar 20 will have engaged with the notch 19 in the slide, which has, upon taking thev position described, disengaged itself from the locking ringT 19. vAs long as the ke depressed remains'in this condition the s ide will be free to coperate with the shifter-har.A This latter, through the described hand-lever 23, is drawn backward avainst the -`-resistance of the spring 27 until tlie index-arm thereon, as Ait moves over the-index 2S,- ,shows that the D has. been brought to the chosen device point In this position the spring-detent 28 will have sprung` into thefproper notch to hold the slide 9.1n its elevated position.
