Suit-able means are preferably 4 95,

eoiiiiects the ratchet-whee 2 9 and the spring I ,di'iiiiifso that the ratchet wheel is forced to tuvii with the spring drum when the latter] f or forked to coiiperate with grooves or slots tion.

During return movements of the carriage and spring drum the pawl 31 slides idly over the ratchet teeth. Projecting forward from the face of the ratchet wheel 2.) an'd in tegral therewith is a beveled pinion 32 which is adapted to mesh withabeveled pinion 33 slidably mounted on the driving shaft 27.

The pinion 33 is provided with a hub 34 e. 4

tending rightward therefrom and surrounding the shaft 27. The hub has flanges and 36, the left-hand flange 35 being formed with a circumferential groove 37. The right-hand flange 36 is provided with a notch which is constantly engaged by a finger 38 extending laterally leftward from a collar 39 fixed to the shaft 27. The gear is adapted-to beslid rightward-along the shaft '27 in order to break tlie connectimi between the source of power or the spring drum and thereby render inoperative the means for feeding the ribbon longitudinally. The finger 38 engaging the notched flange 36 maintains a constant connection between the gear wheel 33 and the power shaft 27 so that in both the operative and inoperative positions of the gear wheel it will turn with said shaft. 4 Q

The 'means for. moving-the gear 33 back and forth along the shaft 27 comprises a forked arm 40 which engages loosely in a groove 37 and is prov'ided with an angular extension or foot 4] riveted at 42 to a slidablo platform or plate 43. The left-hand end of the plate or member 43 is forked or bifurcated to engage with grooves 44 formed oppositely in the front and rear faces of the left-hand lug 28. The right-hand end por-' tion of the plate 43 is bent upright and perforated at 44 to engage the shaft 27which provides a bearing for the plate (Figs 3 to 5). Actuating devices for the arm 4.0 and plate 43 comprise a vertically disposed lever 45 of the first-order pivoted at 46 to the front face ofthe lug 28 and having-its.

lower end olf set forward from the face of the lug and engaging a notch, 47 in the lefthand portion or head of the plate 43. The upper end of the lever 45 is similarly offset forwardand engages in a notch 48 in the left-hand portion. or head 49 of a plate-like member 50, the head whereof is bifurcated 51 formed in the front and rear faces of the lug 28. The member 50 terminates at its right-hand end in a circular enlargement 52 which is bent vertically downward and is formed with a hole 53 which bears on the shaft 27 at the right of the bearing opening 44 in the plate-like member 43. said member 43 cotiperating with the shaft 27 between the part 52 and the collar 39. A planespring 54 is secured by a screw 55. to the righbhand face of Zrhe 111,9;28 and projects downward along s'ai 1 lug. being offset some what from the adjacent face thereof (Figs. 3

connect the gear to 5). Said spring 54 is formed with a hole 56 for the freepassage therethrough of the shaft 27. The lower end, portion of said spring engages in a slot 57 formed in the. member 43. Said spring 54 normally maintains the member 43 and connected parts in the normal relationship shown in Fig. 4. It will be understood that if the member 50 be pushed leftward, motion will be communicated therefrom through the lever 45 to the member 43 which will slide in the opposite direction or to the right and will, through the forked device .40, slide the beveled gear 33 rightward and disconnect it from the gear 32, as shown in F 3. This movement Will flex the spring 54 so that when the parts are released, said spring will restore them to nor mal position. which is determined by the engagement of the member 43 with the lefthand face of the lug 28. The means for thus moving the members 50 and 43 to dis- 33 will be presently described.

M i dway between the ribbon spools the ribbon 18 is threaded through slots in the head of a vibratory ribbon carrier or vibrator 58 (Fig. 1), said vibrator being vertically disposed and guided by an upright guide 59 securedto the top plate. The lower end of the vibrator which is or may be of the usual Monarch style is bifurcated and carries a cross pin 60 which is engaged by the slotted forward end of a horizontally disposed operating lever 61 pivoted at 62 to a lug 63 depending from the top plate. The rear arm of the lever 61 is formed with an arcuate horizontally disposed slot 64, the forward end of which terminates in a downward extension 65. The slot, it will be seen, comprises two angularly disposed" portions. Cooperating with the slot 64 is a pin 66 extending laterally from the top of a link 67, said link being pivotally connected at its lower end at 68 with the universal bar frame 16. A coiled spring 69 connects the links 67 and 15 and tends constantly to urge I the link 67 rearward about its pivot 68. The upper end portion of the link 67 is offset or bent forward and theoff-set portion is adapted to cooperate with a controlling device 70 whichis supportedon and actuated by the driving shaft 27. Said controlling member comprises circular faces 71., 72, 73

and 74 arranged side by side and connected together. The faces 71, 72 and 74 are concentric with the shaft 27 while the face 73 is eccentric thereto. The face 72 is the smallest'in diameter, the face 71 being larger than the face 72 and the face 74 still larger. The short radius of the eccentric face 73 equals the radius of the face 72 while the longer radius equals that of the face 71. The faces are adapted to coiiperate at diherent times with the link 67 to shift the latter and. vary the vibrating mechanism, said faces be- Q T70 and be'aringon the shaft 27 is a hub por which is forked and engages loosely inxthe f groove79. The upper end of said arm is V j ivardly extending 'pin. 82. The pin 82 is ena positioning memberor device "70, said ing' broughtinto operation by sliding themember -vb k nd forth alongthe shaft,

;27. Theconnect-ion between the member 70 and said-shaft comprises a pin extending dlaterally leftward from the member and "'slidably engaging with a'eollar 76 fixedly secured'to said shaft27 by a set screw' 7 Exte'nding rightward from; they member tiori '378 formedlwith a circumferential; groove 79-. This hub coiiperateswit'h menu: ally operated devices which control the powsit-ion of" the member 70' on the shaft 27. vSaid devices may be offtheusual'orsnY, suitable constrnction and comprise Figs. 1, 22nd 4)-.a vertical-arm 80, the lower endof fixed-to the left-hand end of a 'rod 81 which is slidablefthrough the two right-hand lugs 2 8 and carries at its right-hand end an upgaged by a bell crank ,83 having a fixed pivot-Stand connected by a link 85 with a 5 bellcrank 86 pivoted at 87 nearthe front. '1 of the machine and having. a forwardly pro} jecting *arm terminating in a finger piece 88 Said finger piece has anedge 89 which. is adapted to cooperate with detentnotches90 cut in the usual front plate 91.-:[When a uniform ribbon is employed thefinger piece' 88 is manipulated to bring the eccentric face 73 into engagement with-the link 67 -so that thereafter, duringvlette'r space ov 35 ments of the carriage, the link will be caused,

to travel automatically back and forth along the slot 64 and thus progressively vary the widthwise portion of the ribbon presented to the types. When a two-color ribbon like 18 is in use on a machine, then the faces T2- and 71 are brought into use to shift the link I .67. to the roper points on the operatinglever for ringing into 1 play respectively the black field and red fieldof the ribbon. When it is desired to dispense entiiely with. the use of the 1'ibbon,'the fingerv piece 88 is manipulated to, bring the face 74 into action against the link'67, thereby forcingthe link so far forward that the pin 66 is above the vertical slot or angular extension 65 Comsequently,v during subsequent operations of; the fainting keys the downward movement of is link 6,7 will lower the in 66in the slot 65 without affecting the 56 the vibrator will remain ino mul position. I I The link 67 with its actuating pin 66 con-' stitutes a connection or device variably settable or shiftable'to different positions to 60 vary the throw of tho vibrator,- and also to yet another position to render inoperative the train of actuating devices by which the vibrator is vibrated; and this settable device is set or shiftedhy means whichinclude ever {61 and perative in norno useless feeding for. waste "of positioning member being adapted to rendei' inoperative the mechanism fo'r'vf'eed'i'ng the ribbon longitudinally. Thus it will be observed. that the face 74 is at the right of Y the member 70', so that tobring said face 70 into, action it is necessary toishift said mem- Eber" to its extreme left-hand position." ,As meson of thisext-reniesh ift, the end ofthe pinzfiogis'brought into engagement with, the-w;

Th leftward movement ofsaid member-will act as alxp've explainedjthrough-the lever 45 --to force the slidzthle inember 43; forked'dei vice 4O and gear 33' rightward, thus disconfl necting the ribbondriving shaft'from fthef source of power; In ether words, whenever the ribbon w' ibrating niechanisin i s rendered inoperative,- as for m iineographing-= or like i i purposes,- the vlongitudinal v I ribbon" feeding 85 mechanism is at. theqsani'e tilneiautomath.
