The shaitis 23 und 2G are giouinnled in iiangei's Si iiepenfiing from iiipiiezibie oi" uciupiiubie which al'. 2"? are gemsed to veral 33 which is slidably mounted on a bracket 34 mounted on the top plate of the machine.`

the top plate 3. The ribbon 32 is led4 from one spool to the other through a vibrator Said vibrator normally" stands below the writing line so as to render the writing normally visible.

' The partsthus far described may be of the ordinary Monarch construction or of any suitable construction.

The ribbon vibrator is operated by a lever which is pivoted at 36 in a bracket 37 depending from the top 'plate 3, the forward -end of said lever being connected with the lower end of the vibrator by a pin and slot connection 36.. The rear arm of vthe lever 35 is formed-'with a radial slot 40'iii l which there lies a headed pin 4l projecting from the upper end of a link 42 which at its lower end is pivoted at 43 to the universal' 40. When said `pin is at the rear end of the slot as shown'in Fig. 4, and the universal bar is operated, the ribbon wili be moved up as shown in Fig. 5 bringing the upper stripe of the ribbon to printing position. When said pin is in the forward end'of the slot nearer to the pivot 36 as shown in Fig.

6, then when a key is operated the ribbon is thrown to a greater height bringing. the lower stripe thereof to printing position as shown in Fig. 7. When said pin stands in some intermediate position the y ribbon is thrown to a greater height than inFig. 5, and to a less height than in Fig. 7, the exact distance depending uponv the position the pin 4l occupies a't the time.

My improvements, in the specific embodiment thereof shown in the present case, con# lsist in devices for controlling the position of the pin 41 in the slot 40,`although said devices are also capable,v ofcontrolling other forms of variable-throw Ivibrator-operating mechanism. The principal parts of. these devices are mounted in a bracket 44 which is secured to the under side of the=top plate j by screws 45 (see Figs. 11 and 12). Said bracket has two depending arms 46 and 47 from the vfirst of which project at the upper part two stops 48vand at the lower part two stops 50. Said arm 46 also has a vfiat horizontal ab'utment 51 struck out therefrom and just beneath said abutment is a bearing opening 52 somewhat elongated in an up and down direction. A rock shaft 53 has one end projectinglthrough the opening 52 and said rock shaft has an arm 54' rigidly mounted on Isaid end and extending downward therefromat various angles as shown in Figs.' 2', 4 and 6., The stops 50 coperate 8 the shaft 53 has its right hand end jour- I naled in abracket 55 depending from the top plate and on the end of said shaft there .is mounted an upstanding'arm 56 to which is pivoteda'link 57 that extends toward the front of the machine where itis pivoted to a bell crank. 58 having a handle 60 `on its forwardly directed arm. Said bell crank is pivoted at 61 on a bracket 62 which is here shown as secured to the front plate 63 of the machine s o-that the handle 60 is just above, and convenient to the key board of Athe machine. The parts are set. to the respective positions shown inFigs.` 2, 4 and 6 by moving .the ,handle 60 up or down.

' A lever 64 is pivoted in the bracket arm 47 at 65. In Figs. 2J? this bracket arm is sectioned away in order to `show the mechanism' better and the pivotscrew 65 is shown in section. The free end of the lever 64 has an arm, 66'bent ofi horizontally therefrom as shown in Fig. 8, and this arm constitutes a foilower that coperat'es with a cam 67v secured on'the transverse driving shaft 23 of the ribbon feed mechanism by a set screw .68. In vthe Monarch machine .this driving shaft has an endwis'e motion for the purpose of reversing the 'direction of ribbon.

feed and the'arm 66 is made long enough to rest on the. cam in either position of the shaft. A second arm 70 is pivoted to the armi or lever 64 at 71, the ivot 71 being in,

vfront of the pivotv 65 of said lever 64. The lever 64 has an ear 72, Fig. 6, bent oi from the heel thereof, and the arm 70 has a heel ioo 7 3 that is adapted to be pressed against the ear 72 under certain conditions to limit the relative motion of the arms 64 and 70 'in one direction.' Thfactiial motion of the arm 70 is limited byythe stops 48 above referredto. A contractile spring74 is connected at its lower end to a pin 75 projecting from the'lower end of t e arm 5,4 and at its upper end to a pin? 6 rojecting from the arm '70. The upper en of the arm 7()- is connectedl by. a link 77 vwith the pin 4l.

As will be seen by the broken lines in Figs.

2, 4 and 6, the upper end of the arm 54 'is lle made broad and straight so that when the 1 parts are in the position shown in Fig. 2 this arm is held Hat against the abutment 51 by the tension of the'spring 74.l f

The .cam 67 may be of vany one of quite a variety of forms, any form adapted to give a cross feed to the ribbon. being suitable. This cam could be merely an eccentric, for

example, but it is here shown as a snail cam. In Fig. v2 the follower 66 is shown resting on the highest point of the cam, and in Fig. 8, the shaft 23 having turned4 a littie farther, the follower has dropped down to .theilowest part of the cam. It will be seen that in both figures the line along which the position shown in '3 f The type eeogeoe the tensionof the 'spiing' 'Itis exerted isv Within tlie`fl'at`1upper end of the erin 54 so tends'to hold the follower GG pressed zig-einst y the cam. It Will also be seen that in both. these positions theline of force ot' the spring' is at the left of the -pi'vot 7l ot' the erin l0 so that; the tension of the spring tends to hold the heel 73 of said erin down against the ear 72 of the lever (it, thus causing seid lever 64 and erin T0 to more :is a single lever; The result oi this construction that 'the follower G6 and lever G4 are oontrolled by the cani 6"( and that their motions ere imparted to the leve-r and through seid lever to the pin 4l. Beginning with l where :said pin is at the forwrd end ot the slot it() und Where the vibrator has its greatest extent of upward motion1 the pin is slowly drawn to the left' in said figure until it reaches its extienierear position shown in ,Fig 2 when it drops beck tothe posit-ion in Fig. 3. rllhe result o1" this eonstruetion that the successive blows oi the types ige inst the ribbon are alongsueh lines :is the lines 7S inV Fig. 9, the inclination ot these lines being due to the feettliet et the senietinie the pin -llt is traversing the slot the ril;- hon itse'lie is also being' t'ed long" id innlly first' strikes the ribbon netti" the upper part. thereof und gradually strikes lower and lower on the ribbon until the fel lower drops 'troni the position in to that of Fig. 3, whereupon the next typ',

It Will be understood that the erin oecupies the position shown in Figs. 2 sind l3 when the handle GO occupies its nnddle position. It' said handle he moved down to the position vshown in Fig. 1, the erin. will he moved beek to the position shown in l i the left hand end the shaft .m to more downward somewhat on account et the shape lof the upper part of the erin :541 n d its engagement with theahntnient 5l and it for this reason that the hole 52 is elongated :is shown in Fig. 12.
