The main frame comprises two spaced parallel side members l, 2, each bolted to a base 3. Each base 3 is provided with an upstanding guide lug 4 .extending from' front to back at the inner edge, the bases spaced apart to form` a slot therebetween and the lugs vforming togetheraI dovetail guide or slide for the reciprocable work supporting and type inking carriage. This carriage has mounted thereon an inking device for cooperation with type'. disks asl-hereinafter more fully described. VEach side frame has a slot 5 extendingr horizontally rearwardly from its front edge, the middle ofthe longitudinal axis of the slot being on a rlevel with theupper'side of the work supporting carriage, the slots horizontally aligned and together defining a throat into which the goodsrtobe stamped can be introduced to lie upon 4and be yieldably engaged with andytranslated to printing ,position by the work holder, suitable mechanismbeing provided for` translating the work holder rto its printing or stamping position and for withdrawing or returning the same to initial -position. l y Y Y Rotatably mount-ed Vcrosswise at a point approximately midway between thetop and the bottom of the members l, 2 and insaid members, or plates, is a shaft 6 circumferentially grooved as at VV7 and having a pinl 8 engaging the groove permitting rotation but preventingrendwise inovementof the shaft.

The disks lare rotatably engaged upon the hub face to face, each being provided with a lateral. ring shaped projection 2lacting to space adjacent disks sufficiently for the slidable introduction of the setting plunger abutmentstherebetween. The disks are held from lateral movement by circular members 22 keyed to vthe shaft one at each side of and engaging the face of an end disk of the series', each member being provided for this purpose with a marginal flange fitting over the endv of the hub and engaging the side face of an end disk Vsuiiiciently to permit rotation of the disks.

Whenever the operating lever is pulled downwardly to a position shown in Figure' 3, the hub 'supporte ing shaft is rotated in eounter-elockwise direction and the hub correspondingly rotated, andl throughfthe yielding connections carried by the hub, the disks selectedfor rotation are" also turned, the rotation being liniited in correspondence 'to the position ofthe plungers. f A n I nterceptz'ng plzm'gerfabutments.
As heretofore mentioned, a given disk is Aadapted to be stoppedfwith `a given charac-` ter on itsperiphery in printing position, this by selective depression or translation of plungers` into the rotative paths of the lugs ofthe disks. .i I
These plungersare mounted" in radial relation and when` depressed are adapted to be positively locked in depressed. condition until the disks are brought to printing position, and until theprinting operation is complete, after which they are returned initial positions and again locked.
[The plungers are mounted for Vreciprocation upon suitable cross-f bars held at opposite ends by respective side'frames land 2,

comprisinginfthis instance five members, with the exception of one'y of ythe end' rows,l have theirends projecting between adjacent f spaceddisks with the ends normally lying just within the disk periphery. See Figure l in which position they are. yieldably,V looked.
Each rplunger 40 for a given machine isv substantially identical. Each has a substantially elongatedrreetangular form, is` provided withfa central longitudinal slot 41 through l*which crossguides42 extend, the guides in V'this instance extending from side to side ofr-theeasing andbeing radially artheV plungers. Theseguid'esare of less width l than the? length of, the r` slot in the plunger to allow vlimited reeiprocationof the plun gers on 'the guidesand the yplungers are heldin positionstrietly at right angles to the guides byauxiliaryl guidestrips 43 somelying between the plungers'andvothers outside .of the ranged corresponding. tothedisposition of end members of the series (see Figure 2). The guides also act as stops to 'limit outward translation of the plungerto dispose their inner ends adjacent the peripheries of the type disks.
vEach plunger'is provided with aligned lugs 44, 45, extending outwardly from relatively opposite edges at right angles to the plunger axis, the lugs adapted to be engage-d by key. abutments. Each plunger is moreover provided with notches 46 extending in# wardly from relatively opposite edges, which notches are adapted to be engaged and positively held by plunger locking elements 47, 48, after the plunger is forced inwardly a predetermined distance by a key., Each plunger in this instance has adjacent its inner end twonotches 5() relatively staggered or offset crosswise of the plunger, each of which is engaged or engageable by a tooth 51 of the respective locking elements47, 48, when the plungers are in their uppermost or re. tracted position, thus yieldably locking the plungers in that position. E our additional notches 46 are provided on each relatively o aosite side also arranged in staggered reb Cnt? c lation in such manner that opposite notches (it in a clockwise direction.
may be alternately engaged with correspondingprojections of the locking elements, thus providing in this instance eight locking positions for each plunger, which correspond to the bringing of as many type characters to printing position. n

vand are supported at opposite ends in suitable guidcs attached to the side' frames 1 and 2, theinner plate 47 having a spring 60 for drawing it in counter-clockwise direction, and the outer h aving a sprngtil for drawing Corresponding side faces. of the slots of therouter member are chanifered in one direction, as shown, to
form teeth Vfor engagement withthe `corresponding notchesat one edge of the plunger, and corresponding"edges of theslotsl of the inner plate are similarly chamfered inthe lopposite direction for. engagement with the notches at the opposite edge of the plungers. The ends of the plates are upturned substantially in parallel relation asat 63, and a shaft 64 extends crosswise of and is journaledV in the side frame, passes between the upturned portions of the plates. andhas keyed thereto a cam element 65 adapted whenthe shaft is ,i
rotatedto positively throw the plates in 0pposite Vdirection and withdraw the chamfered' portions or teeth 51 from the notches of the plungers. This releasing action takes place after the printing` operation and as the operating lever is pushed upwardly from its lowermost position. Springs 68 for retracting the plungers are attached thereto and to i arms or brackets V69 which are suitably secured at the opposite endsto the plunger sup- Y porting bars 42, there being one of these brackets for: each row of springs (see Fig-iV The brackets 69 together s be less than the angle included between any` two stops 25 to prevent the last stop of the' series from first engaging any one of the plungers, it'being necessary that Ythe'stops engage or be capable of engaging the abutments successively, yin the order of their arrangement on the disks. This for the reason that the last lug of the Series must clear the last abutment plunger before the Afirst stop engages the first abutment, because if-otherwise, an advanced stop might reach an Vabutment out of order and therefore fail to bring the proper letter to'printing position. j v
The plungers are adapted to be thrown inwardly from a normal position adjacent the peripheriies of the disks, to bring the eXtremity of any oneof the plungers to a position for engagement by one of the shoulders ofA one of the stops carried upon the facevin each disk, and in this manner rotation ofthe disk is limited by the engagement of it-s stop against the plunger. Each disk in this rin-v stance lias eight stop shoulders arranged seriatim on a substantiallyr spiral line, successive shoulders being spaced outwardly from the axis of the disk supporting shaft, distances corresponding to the distances that the plungers are adapted to travel as result of .selective engagement bythe keys. These shoulders may be made, as separate pieces,
and fastened in posit-ion or the vsame may be Y cast integral with or even punched Vout fromA` the disks. Moreover, the number of shoulders may be decreasedfor,increased at will according` as agreater or lesser number of type characters are desired foreach disk. .fr 'Y Key carriage md 7963/8.
Thekeys are reciprocably mounted india translatablefrai'ne or carriage which has substantiallythe form of the segment'of a closed end cylindrical drum, the curved'wall 7 5y thereof beingsubstantiallyl concentricy izo with the axis of the disk supporting shaft 6,y
and the keys being mounted in spaced relation longitudinally and radially of kthe frame, and extending inwardly radially in a direction toward the fdisk supporting shaft.
These keys are adapted for selectively and successively engaging and operating plungers, the inner extremities of which are, by this operation, in rotative paths of the projections 4or shoulders arranged on one face of each disk. After a given plunger has been thus set, by translating the same inwardly the disks are manually. rotated, and each continues to rotatel until one abutment or stop engages the plunger, thus bringing one character of the disk to and stopping the same at a given point, which corresponds to the printing position of the line of characters, so disposed, and thus set up.
The frameA is supported for translationr longitudinally parallel with the axis of the disk carrying shaft 6, upon front and rear tracks 76, 77, each having a groovein its upper face within which are engaged the rounded peripheries of rollers 78 rotatably attached to the curved frame wall at the front inner side thereof, and to a cross bar 79 extending between and attached to the frame end walls 95, at the rear. The frame is thus mounted to act as a key-carriage adapted to move longitudinally of the axis of the disk supportingshaft above, the disks and plungers associated therewith.
The outer curved wall of the carriage is slotted, each slot being of suflicient width to slidably receive the thickened upper portion of the key stem which is thus guided at its upper portion. The inner ends of the keys traverse slots provided in cross pieces having their ends suitably secured in the end walls of the carriage. Pairs of rows of keys are mounted with their stems in parallel relation to one another and to vthe parallel row rof plungers with which they cooperate, as clearly shown im Figure l.
The upper end of; each side plate l, 2, is cut to substantially conform to the configuration of the side walls 80 of thekey carr1age,'which side walls are curved as sh-own and notched out as at 81 along their curved peripheries vto provide clearance relative to the plunger supporting cross plates or supports 42.
The keys are preferably formed by stamping sheet metal, and each has an elongated stem portion 85 and an arm 86 at a right angle thereto terminating ina projection 87 as a plunger-engaging abutment parallel with the stem and with its broad faces'in planes parallel with but offset relative to the planes of the corresponding faces of the stem. The length of each arm 86 carries according as the key stem is to be spaced farther from or nearer to' the .first member of the cross row of plungers, thekeys being lspective rows disposed. in. crosswise and circumferential rowsk corresponding to the *arrangementV of the plungers operable by them. n
lThe arrangement isV most clearly shown in Figures 6 and 8 whe-rein the superposed relation of thew'plunger engagingv projections or abutments, as well as their varying length are shown. f
It will be noted that in this design two parallel cross `rows of keys comprising four members each are arranged in parallelism to act selectively and consecutively upon the members of aQcorrespondingrow of plungers, the plunger engaging projections of rebeing superposed andregularly varied in length. In other words, `the length of each successive projection, for example beginning with the shortest, is increased over thatof the preceding one by a certain amount, corresponding to the linear spacing of the notches .46.` Thus whena given key is fully depressed a plunger associated therewith is carried inwardlyy a distance equal, in this instance, to one-eighth of the total distance of the` possible plunger travel.Y
The number of plunger engaging abutments is however optional, as well as the relative lengths ofthe projections o1' abutments 87, vconformably to the number and spacing of the plunger notches, and Vthus may be increased orfdecreased as desired,
l and it is to be understood thateach key acts onlyv to throwthe plunger inwardlya'pr'edetermined distance to form an abutment against which a certain one of the'disk stop .shoulders will engage, to stop a certain character on the disk at printing position.V Each stem is preferably cappedy by the usuall linger disk marked with a ,suitable character.
kThus there are for each/pair ofl` double row .of keys, eight abutments, each of a different length and each spaced a different distance from the, lugs 44,45, and corresponding to the distance which a plunger is .to be translated inwardly. Four of these abutments are operable against a lug 44 and the other four againsta lug 45. lMoreover, the spacing of the inner ends of the lugs op-V positely from the abutments corresponds to the staggered relation ofthe notches 46 of the plungers, so thatwhen a key is` fully depressed it will translate the plunger and cause the corresponding notch to be engaged,
and locked by the plates 51, 55. I Each key is,.theref0 re, adapted forthrow ing 'the plunger inwardly to one position only, and after depression, release and return `of the key carriage is moved to a position wherein the abutments are disposed for selectively engaging and translating the next succeeding plunger.
A single row of .plungers only may be used, a larger number Vof notches 46 provided therein, and a corresponding number of to the side and to the curved wall A75 of the carriage. A spring is provided for each stem or key, connecting with the stem at its inner end and at its outer end with the cross piece 89, adapting each key to be automatically returned to initial position after depression. Certain of the cross pieces 89 are notched or slotted as at 94 Jto-permitthe thickened portion 91 of the stem to pass vtherethrough when the key is depressed. The inner circumferential row of cross pieces 92, supporting and guiding the inner ends of the stems, are bored or cut out as at 93 adjacent the stems for the passage of the springsand securing device, the stems passing through and being guided by slots 96. these slots and openings 93 intersecting one.` another. Each key stem is thus supported at two points intermediate its endn and is continually supported both in normal and depressed positions. By selective key action a plunger is'depressed to that degree necessary to bring one notch only into locking engagement with one of the locking ele- ,ments 47, 48, and upon actuation of the elements after the printing operation, the plungers are retracted by t-he coil springs 68, to initial position, with one of the lateral lugs 44 in engagement with one of the key abutments. Thus, upon actuation of the locking elements 47, 48 to withdraw the projections from the plunger notches, the plunger will'be returned by the spring 68 to its initial position. f
The relation of the key stops, plunger, notches and radialspacing of the stops of the disks is such that each plunger can, in the present machine, be set at eight different disk-stopping positions. It is l evident, however, that the number may be increased .or decreased according as more or less printing characters are required on each disk.
As the disks are brought to printing position by swinging the operating lever 35 to lowermost position they are simultaneously micrometrically aligned and locked together, to maintain the selected printing characters in strict alignment during the printing operation, and at the same time the operating lever is locked in its lowermost position. Means for accomplishing the above results comprises the following mechanism:
Mounted on the inner end ofl the operating shaft 34 and pinnedthereto is a dlsklike plate lying against the gear 33.
(See Figure4.) The plate has a radialY notch forming a shoulder 101 and also has a radial lug 102 substantially diametric to the shoulder. lVhen the operating handlef yengage a row of disk notches to positively micrometrically align and lockthe disks in printing position, and to maintain them thus locked during the printing operation..A A spring 109 urges the locking element to locking position as well as engaged lhook 103 with shoulder 101.
Plunge?" reims@ mechoy/Liam.k
Means is also provided for operating the latch plates 47 and 48 to release the plungers after the printing operation, and as the operating lever starts from its lowermost to its initial position. vThis mechanism comprises a disk 110 rotative with the Vlatch shaft 64,
ythe disk having arstop pin 111 projecting laterally therefrom. Swingingly mounted upon the shaft 64 and engaged against the disk face is a detent 112 having a spring 113 forcing it toward the stop pin, the detent being thus adapted for yieldable movement in one direction -for non-rotation of the shaft, and forl rotating the shaft 64 when urged in the opposite direction against the pin 111. Y
Substantially simultaneously with the disk locking action, as the operating lever 35 reaches its lowermost position to set the disks in printing position, and traveling in counter-clockwise direction, the luv 102 passes to the o-pposite side of the swinging detent 112 which yields during such passage in a clockwise direction, thus disposing the lug` in aposition to engage the detent and rotate the shaft 64 in counter-clockwise direction when the operating lever startsback to its initial position. As this shaft rotation takes place the latch members`47, 48, are translatedby the element 65 (see Figure 1) to release position, 'allowing the plungers to resume initial position.
Before the operating lever can be returned t'o-its original `position however, the hook 103 must be released from the shoulder 101, and nfor this purpose a release lever 115 is mounted at the outside of the frame upon a short shaft which is rotative in the frame,V
projects at both sides thereof and has pinned to its inner end a curved finger 116, having a lateral projection 117 which is engageable with the lever 104 to throw the same downwardly (see Figure. 4).' A spring attached to the arm 116 and frame 1 normally holds the lever 115 against a stop 116. The outer extremity of the release lever 115 is related to the handle of the operating lever in such manner that with the operating lever in its lowest position the operator may place his thumb beneath the release lever to raise the 'same slightly and cause the finger to force the lever in counter-'clockwise direction, releasing its hook 103 from the shoulder, and at the same time rotating the shaft and withdrawing the tapered projection 108 from the disknotches, thusl'eleasing the disks which are then rotated and brought to initial position as the operating handle moves upwardly.
One tooth of each disk has a radial eX- tension 120 thereon as a stop, adapted to engage a. stop bar 121 secured crosswise at the rear of the machine. y This stop acts tolimit disk rotation in both directions, engaging the upper side of the bar when the disk is in initial position, and the opposite side after the greatest rotation of the disk. In order to prevent this tooth extension from being brought to printing position, one of the key abutments or project-ions is omitted, so that the depression of one of the keys will not translate a plunger sufliciently to intercept the corresponding stop of the disk. The disks are all rotated, whenever the hub rotating shaft 6 is rocked, and whether the plungers are or are not set. When any plunger is not in disk interceptingv position, the corresponding disk is rotated until its stop 120, engages the bar 121, which is the limit for both disk and operating lever.
Vhen the disks are in normal lor initial position, each with its stop engaging the upper side of the bar, that tooth having a zero or other correspondii'ig character thereon will be at printingv position, and if under these conditions, the first ,plunger depressed'to its innermost position, that disk will remain in initial position, although others may rotate when the operating handle is pulled downwardly.
Key carriage advancing mechanism.
tion and control by the segmental plate 125 operably connected in this instanceat its upper edge with the element which controls the key carriage advancing or spacing mechy anism. i The plate 125 has its center of curvature in the type'disk axis, is circumferentially translatable, and is mounted adjacent the inner face of the curved side 75k of the key frame between pairs of suitable rollers 126 engaging opposite'sides of the plate adjacent opposite ends, and held upon the spaced radial arcuate plates 95 respectively attached to the side and top of the carriage frame.- Theplate 125 is provided with slots 12,8 equal in number to that of the keys, and
each key slidably traverses a slot which is fonthis purpose of a width slightly greater than'that of the thickened portions 91 of the stems 85. Each key when in initial posi-r tion has, one face of the thinner portion of its stemengaged with one. face of acorresponding slot, as in Fig. 1, the plate being yieldably urged in clockwise direction by the spring `150 of the escapement mechanism described below.
When a. key is depressed, the plate is translated kin counter-clockwise direction and the carriage advanced approximately one-half the distance between centers of adjacent circumferential vrows of plungers. The remainder of the movementtakes place only after the key has resumed its initial positionthe plate then being drawnl in clockn wise direction to the position shown in Fig ure 1. The plate may be connected with and made to operate any .suitable carriage release mechanism but performs -a necessary function inasmuch as it proeures the proper stey-bystep advance of vthe rcarriage mounted at the rear, oney portion on the cross bar 79 which supports the carriage f rollers, and the other Aupon a depending bearing block 135l secured by a screw to the wall 7 5v of the carriage.` This block has a forward extension as va bearing through which eXtendsa shaft havingpinned theretoV at one end a vertically disposed arm 136 terminating in ai pin engaged through an opening inthe plate 125. Keyed at the op? pcsite end' of the shaft and extending horizvontally is'an arm 137 engaged within a slot 169formed into the edge of one arm 138 of an escapement lever pivoted as at 140 to the block. At the opposite Side of the pivot the lever has the usual escapement Wheel engaging arms 141, 142. The escapement wheel 145 is rotatably mounted or pivoted'upon the bar 79iin propei'relation to the arms of the lever and has attached thereto a spur gear 146 the teeth of which mesh with those of a rack v147r secured longitudinal ofand at the rear of the track 77. L
The carriage is positively drawn in advance direction by any suitable means such spring, acting to rotate a drum 148 suitably mounted upon the frame, to which is attached one end of a strap 149 connecting at the opposite end with the carriage. Vhen released through operation of the escapement the spring acts through the drum and strap to draw the carriage in appropriate direction. The carriage must be returned to its initial position by hand.
rli`he escapement lever is operated against the action of a spring 150 which yieldably holds the same in position shown in Figure 5 and functions through elements 137, 136, to draw the plate 125 in clockwise direction and yieldably hold the same as shown in Figure 1.
Carriage advance is obtained as follows:
Referring to Figure 1, when a key is depressed the cam or thickened portion of the key 91 translates the plate 125, rocking the escapement lever against the action of the spring 150 allowing the carriage to move while key projections are engaged with pluno'ers, this movement being some fraction Y of the total movement of the carriage, and sul'liciently small to prevent engagement of a key projection or abutment with the side of an adjacent plunger. wWhen the key reaches its initial position the plate 125 travels in counter clockwise direction correspondingly rocking the escapement lever and permitting the escapement wheel to advance another notch, thus advancing the carriage and 1oringing the key abutm-ents above the succeeding plunger or row of plungers. This movement of t-he carriage takes place both upon key advance and ret-urn.
General operation.
lV ith the operating lever 35 in vertical position the op-erator depresses the desired key or keys, pushing them to their limits, as a result of which certain plungers are translated, stopped and locked with their inner extremities disposed for engagement by a certain abutment of a selected type disk. rlhe key frame is advanced part way toward the next circumferential row of plungers, during key and plunger translation, and as the key reaches initial or returnposition the frame again moves and completes its advance, bringing the key abutments in position for engagement with the succeeding plunger' or any member of a circumferential row of the same.
After the key depressing` and plunger setting operations the disk shaft rotating lever 35 is operated by pulling downwardly to a position shown in dot and dash lines in Figure 3, the disks being by this means rotated to bring their abutments in engagement with any advanced plunger, thus stopping the disks with a certaincharacter in print-Kv of the disks have been stopped, in order toV bring the remaining disks to theirlimits of movement.
When the lever reachesits lowermost position, which corresponds to this set positionv of the disks, the disks and lever are simultaneously locked and interlocked ure 4) by the elements 100, 101, 103, 104,
1.06, 108, etc., and the plungeru release mecha-V nism including the elements 102, 112,. 64, is conditioned for release action, as the result of the engagement of the locking element 103 and radial shoulder'101 of the ratchet disk 100. Simultaneously with this interlocking action, the element 108 engages, aligns andA locks the disks by entering the slots formed between the radial teeth of the disks. Y
Substantially simultaneously with the in- (see Figterlocking operation, the radial projectionl 102 passes to the opposite side of the detent 112 to a position for engagement therewith when the operating lever 35 is raised.
The goods is then brought 'against the printing characters or line of the same and the printing operation accomplished.
` The disk setting lever 35 is now again grasped and the thumb engaged beneath the releasing lever 115 which may be called a plungerlock, vdisk-setting and disk-interlock releasing lever. Y As this lever is pushed ing theirst part of its movement, the `plunger lock and release mechanism is operated, the plunger Vlocking plates simultaneously upwardly and dur# actuated to release all the plungers which are then retracted to initial or non-stop intercepting position.
During th-e movement of the disk shaft ro* tating lever 85 back to its position shown in Figure 3, the disks are returned to their initial position with their projecting lugs'120 engaging at the upper side of theV bar 121 thus clearing the machine and conditioning the same for another setting operation'.l
