Be it own that I, ROBERT H. S'rRo'rHER, citizen of the United States, and resident of county of Essexand State key 1s"partially depressed. Fig. .5 is similar of New Jersey, have invented. certain "new to ig. 1 but shows the parts when the-kc and useful Improvements in Type-VVriting is fully depressed.

This platen,

knownin the art, is mounted on having a roller that rides on a shift rail 5, which shift rail is supported by two posts 6, which in turn are supported by a shifting bar 7 and said shifting bar, is supported by two posts 8, which are pivoted atthcir lower ends to the shift key levers 10. Asthis shift mechanism is well lmmvn in the art it has been 1056 machines wherem'the platen is shifted. In the present; instance I have shown the inlied to a Remlngton N o. 10 typearranged to glve two extents: of

These view of some of the mechanism, parts being key levers also overlie a universal bar 12 F' which is hung at its ends by wires 13 from arms 14 projecting toward the reari'rom a rock shaft-'15, which at its ends is mounted on pivots 16.

The lever is a floating lever,

pivoted at 33 to another lever 34,"w hich in turn is pivoted'at 35 to the stationary framek work. These levers 30 and 34 can'be variedhave been given in the present instance has'" been determined to some extent,-at least',=by the construction of the-mgchine in which very considerably. in theirs-details of eon-1 struction and the precise i form that they they are shown.

a branch 40 connected with the body-of said lever by a yoke piece' 41 andthe-pivot'35 consists of two posts or studs project-ing'inward toward each otherfrom the bracket parts 36 and 37. The pivot-33 consists ofa pin or axle passing through the lever 30 and entering both branlches of the lever 34. The link 31 is pivoted,to the lever 30 between the two branches of the lever34. of advantage-in a shift machine because it enables the lever 30 to pass. at times through the piv otal axis of the lever 34. It will be'noted' that the pivot 33 is between the-pivot 35 and the vibrator and that the free end of the lever 34 nornmlly stands as shown in Figs. 3 and C-ahove the free end of the lever 30 and behind the stem of the vibrator. The

- parts are held in this position by::. spring isltdown v ar shiftin In the Remingtonmachine there is a i "m bracket 36 having .a depending branch""-37,{

the tens on of'thespring 42 at-fii'st tends to hold' the: free end of the lever 30 down against the-stop' 44' so that theefl'ect is to swing thelever 34 downward on its fulcrum 35.

When, the lever 34 strikes the stop 45 the pivot 33 becomes a fixed. ivot and the lever 30 becomes a lever of the storder. A continueddownward motion of the uni versal bar and of the link 31 causes the free end. of the lveverp30 to rise to the (position shown in Fig. 5 where it is arreste by the ,pin 27 striking against the underside of the stop 45, which stop is, therefore, as it were,

pinched \in between the two levers. It will be seen that the vibrator is thrown upward positively and that-it is positively arrested when the pin 27 encounters the. stop 45. It will also be seen that the tzperation takes placejust the-same whether. e platen is in the upper case'positionor the lowehc'aseposition. When the parts -are moved to upper case position, as shown in full lines in When in contact'with the a 15s51d l'stopsgconsist of ears ,:1nda1so the lever 3ft, which last Fig. 8, the s t ie ,vibrator upward to-the'same extentas the platen is shifted It also carries the to the same extent is pivoted to the lever at 33. a keyis operated with the parts in this upper case position the lever-34 will move down until .it strikes the stop 45, after whichthe lever 30 will'move w upuntil arrested by said stop and the vibra t- 4.6 is moved under the lever 34:- If, then, a

key be depressed said lever 34 will be arrest- 23 ed almost. immediately and the downward motion of the link 31 will beginalinost'immediately to move the vibrator upward, and it will move itipwardfiuntil the pin 27 is arrested by the stop 46, as

also is the same whether the platen its upper case or in-its lower case positlon;

so and 46 will moved 'out of levers 30 and such inoperative positions th the universal bar will merely 34 to bev moved down almost is desired to use the machine for miineo- 4o graphing. c

in order to adjust the slide bar 47,.said. slide bar is formed as shown in Fig; l with a. vertical slot 5! into which a pin 52 ex-f tends from an arm .33 mounted on the rear end of a horizontal shal't 54, which shaft extends to the front of the machine where it is provided with a finger button or milled head :35 for turning it. The shat't'fA may be journaled in brackets 59 may be provided with in device and with any suitable means for retaining it in any one of the three positions to which it is intended that it be adjusted.

It will be perceived that by suitably manipulating the button 05 the ribbon mechaany suitable indicat-' .nism can beset for either niimcographiug' or for writing on the upper st ripe ot' the ribbon or for writing on the lower stripe ol the r bbon. 'lhe'adjustment ol the said 50 button 5-3 has no other client th'airto adjust. the slide "ti, which sliderarrics the stops 45 and 46. It will be noted that the ribbon vibrator can be caused to more to a groan-r or loss-' ex'tentto enable writing to be done from either stripe or from neither stripe I i *kipaass carries the lever 30 a' n d shown in Figflt, It will readily be seen that this operation 56 and .57 and it of the" ribbon .case position of the platen; that the control of the vibrat dr. is

functions are ohtained 'by extremely simple 'mechanism," the parts operated by the universal bar consisting only of the link 31 and the two levers 30 and 34L and the adjustable part consisting merely of the stops 45an'd46,"" Figs. 8 and 9 show an adaptation of my invention to the Blonarbh. typewriter in winch the type bar segment is shifted and in-which the platen'has no shift-in movefigures 60' mental front plate 62-which occupies part of the space betwee'nrthe type bar segment and tllQtOP plate. The- )latcn is represented at 63 andat 64 is the racket which supports the guide 65 and the ribbon vibrator 66, through which threaded the ribbon ($7. The lower end of the vibrator has a cross pin 62' that plays in a slot in the free end 0 an operating lever 70, which lever is pivoted: at 71 to a second lever 72, which last is pivoted t"o"tl 1e underside of the top plate as by .a screw 75. The lever-" isconnected by a bar frame in the in the Monarch machine and -hnk iszcontrolled by a spring 77 con necttal-tat one end to the link and at the 7 other and at '78 to the lever 70. Said spring linltt ((lfwith; the universal manner .usual "ll ie perceived that the tension of the spring 77 is exerted to hold both the levers 70 and 72 down at their forward emlsfi 'llle lever. 70 is't'ormed with a branch 80 which extends downward. and thencedorward, as shown, so as to lie below the: level of three stops S1, 82 and 83 consist'iug'ofcars bent olf iron: a slide bar 84., which slide bar is formed with slots 85 through which iass screws (1 that are threaded into the plate (32 from the rear thereof. As shou'n'in Fin; 9, the arm 80 is offset so as to bringits lower end dirchtlv hcncafhthc levers T2. The stops 81, H2 and are arrangetluii thestcppcd formation Fig. 9: that is to say, they are an-mined one above another higher stops being, each v to the stop below it.

The bar 84 can he means of a handle therefrom through a slot Said bar 8% is yielding'ly retained in any {one of three-positions by ineans of a .detent 1 spring adapted to engage at will with any i one of three notches 91 in said bar 8% stands in the shown in and. the two right of the moved lengthwise by S7 pro ectiug forward at 73-to a hanger 74 secured and in either upper or lower positive, and that these 23 cars (it to which 15 secured by screws a se::-

S8 in the plate 62.,-

f Fig. i.) and a key is operated and the link '7 6 is drawn down,

the first part of the key stroke will cause arrested by the stop 82.. The remainder of a vent positively any motion of the vibrator' '40 levers 70 and 72 in the second form, are two '45 in thenaction "of the ribbon vibrator is shown prevents the lever (2 from moving] downward. The pivot 71 is thereforea fixed i pivot and the lever 70 acts as a lever of the 5 first order, which is operated by. the link 76 until arrested bythe arm 80 striking the underside of the stop 81, which stop will then be pinched in between the two levers. The ribbon is thus thrown to its highest point and the actuated type liar will co-actwith the lower stripe thereof. If .the bar 84' be moved one notch to the right in Fig. 9 the middle stop 82 will be brought into operat-ive position. If, now, a keybe depressed 5 the lever 72 to move downward until it is the strokewill cause the lever 70 to move upward until it is arrested by the same stop which positively arrests'the vibrator at pro- 2 per position to write from the upper stripe of the ribbon. If the bar 84 be moved another notch to-the right in-Fig. 9, the stop 83 will be brought to operative position and it now a, key be operated the lever 70, and

with it the vibrator, will not be thrown up to bring the ribbon to printing position, the.

' whole motion of the link 76 being expended idly in moving the lever 72 downward. Thestop 83 has no other function than to preat this time. I do not consider this stop 83' to be necessary but it can be employed if desired 'or if found advantageous, and itwill of course be obvious that a similar stop can be used if desired in the form of the invention shown in the other figures of the drawing.

It will be perceived that the levers 30 and 34 in the first form of my invention and the parts connected together and with the print ing keys in such a way that-the sum of the motions of said two parts at a key stroke is substantially constant and that the variation brought about by variable stopping means variably distributing suchconstant sum of motions between the two parts or levers. Stated in another way,.these two parts or levers are given at each key stroke a definite amount of relative motion which may be variably distributed, between said two parts. It will also be perceived that primarily ,it is the lever 34 in the first form of myinvention and the lever in the second form that is arrested by the stop, a greater or less part of the keystroke being lost in moving this lever to the stop. It is not absolutely essential that the floatinglever be arrested by 60 said stop or by any positive stop. The action of the parts is rendered more positive and exact, however, byhaving said floating lever also arrested and with it the vibrator itself.

66 Variouschanges, other than tho'se spedihczftlly described, can be made in the details 0 construction and arrangement without I departing from my invention;
