To all 10/1 omit may concern Be it known that I, Qrro P TERMANN, a citizen of the Republic of Switzerland, and

a resident of Groton, county of Tompkins, and btate of New York, have lnvented certam new and useful Improvements in Typeits normal working position to :adapt the machine for transportation or other pur poses, and which mechanism is-so constructed that the parts of the vibrating mechanism always remain in constant registration and cooperation both when the carriage is in its folded and in its working positions; and to provide simple means whereby the said'mechanism may be operated by the keylevers when the carria e is in its Working position and be moved out of cooperation With said levers when the carriage is inits.

folded position.

Another object'of the invention isto pro- I vide simple and efficient mechanism which is adapted to positively'move the ribbon different distances to cover and uncover the printing point in order that the ribbon may have a plurality of fields or zones of diiferent colors thereon or which will permitthe ribbon to remain inactive in order that stencils may bemade.

Other objects of the invention are to provide simple and eflicient means which will prevent the ribbon from being thrown too high when the keys are operated with unusual force, and which will positively restore the ribbon to one side of and below the printing point; and to provide means whereby-the ribbon vibrator may be readily and easily operated and always held substantially rigid and with little or 'no play Whatever l A- further object of the invention is to provide a mechanism whichis s mple H1 con-v struction and'readily accessible and convenient for use, and which mechanism may be substantially entirely I assembled away from the machine andiea'dil-y applied thereto.

A still further object of the invention'is to provide mechanism which may be manually adjusted so that in one position the ribbon may remain inactive in order that stencils may be made, in a second position the vibrator operated to present one field of the ribbon to cover and uncover the printing point. and in a third position to increase the throw of the ribbon and thereby present another field to the printing point, and the parts so constructed that the ribbon after printing will be immediately'restored to its normal position away from the printing companying drawings, which form a part of this specification, and will then 'bevpointed outin-the claims at the end of the description.

Fig. 9 is a fragmentary sectional plan through the vibrator and taken through the line IX'IX of Fig. 8. Fig. 10 isv a fragmentary plan view showing the adjustable device which is mounted upon the'rock ng frameand serves as a means for moving the vibrating mechanism; and Fig. 11 shows a different form of ribbon vibrator arm.

While I show the invention as applied more particularly to a typewriting machine in which the carriage and platen are folded forward, it will be understood that the invention may be applied to other forms of machines. The frame 10 has a rear member 11 and side members 12, and supported between the side members 12 are transversely extending rods 13. As shown there are-three rods arranged in parallel relation and each rod is adapted to support a bank or set of keylevers 14. These key-levers'14' are suspended from the rods 13 and at one end have the usual operatingkey and adjacent to the pivot may be held bya spring 15 to a transversely extending plate 15 tending normally to force the outer end of the key-levers upward. Each key-lever at its inner end may be vconnected by a link 16 or otherwise to 'a typdbar (not shown). and each key-lever is adapted toengage a part 17 of a universal bar 18. The universal bar 18 has upwardly extending arms 19 and these arms at their upper ends are pivoted to the arms 20 of There are two I levers 21 which are-located'at therear and on oppositesides of the machine. Each bellpart of the frame and has an end 23 which crank lever 21 is pivoted at 22 to a suitable is adapted to'engage a slot 24 located in the; vertical arms 25 of a rocking frame 26. This rocking frame has two vertical arms 25 which are pivoted to rock on a transversely extending rod 27 at their lower ends and at their upper ends said arms 25 are connected by an integral and transversely extending bar or plate 28. The rod 27 is held at its outer ends in arms 29, which latter are held to a rod or shaft 30, and these arms are adapted to be operated by suitable platen-shift mechanism (not shown), to adapt the rocking frame to be elevated.

The rod 27 is connected at its ends to vercally movable .posts or slides (not shown) which are movably held at their upper ends in hearings or. guides 31, and each 0st or slide is secured to a barE32. These ars 32 have similar. bars (not shown) pivoted thereto, at 33, and to these latter bars, is held a carriage bed 34 along which the can riage 35 is adapted to travel in the usual way, said carriage being provided with a 'pact when not in use for transportation or suitable platen 36 about which the work sheet is adapted to be held. The carriage 35 and carriage bed 34 is adapted to be folded over and forward with the pins 33 as a pivot so that the-platen 36 will rest upon the forward part of the frame of the machine and so as to substantially overhang the keyboard of the machine and in such a way as to reduce the cubical contents 7 5 of the machine to make the same morefcom-q other purposes. The parts thus far described are not claimed specifically herein and may be of any suitable or preferred construction.

A bracket 37 has a transversely extending arm 38 in which are openings 39. Screws 40 have their bodies passing through said openings and have their threaded portions engaging threaded apertures in the carriage bed so as to rigidly hold the bracket 37 to the bed. This bracket has a forwardly extending arm 41 which connects with an integral and horizontally arranged arm 42 which extends substantially parallel to the arm 38 but is slightly higher than said latter arm. The arm 42 of the bracket 37 has a slot 43 extending lengthwise thereof, and adapted to enter said slot is a roller 44 caras a projecting part from thelarm. 46 of a ribbon vibrator 47. The vibrator arm 46 is vertically arranged and has a part bent or folded upon itself, as at 48, so that the pin may be rigidly 'held therein. The vibrator 47 has a horizontally extending arm 49. This arm 49 is enlarged at one end, as at 50, and is provided with a slot 51 through which the ribbon may be passed and'intersecting said slot is a short slot 52 by which the ribbon may be readily threadedinto the vibrator. The vertically extending arm of the ribbon vibrator terminates in a boss or part 53 which is pivoted by means of a screw 54 to an upwardly extending and integral curved arm 55 of the bracket 37. By this means the end 50 of the ribbon vibrator may be moved up and down with the screw 54 as a pivot to cause the ribbon to cover and uncover the printing point, and the vibrator guided by the slot 43 androller 44,

-ried by a .pin'45 which extends downward so that the ribbon vibrator will be suitably I held while being moved on its pivot. To operate the ribbon vibrator to permit difi'erent zones or fields of the ribbon to be presented to the printing point and to posi'' aively operate the ribbon vibrator in both directions to cover and uncover the prints ing' point or to permit the vibrator tore" main inactive in order that stencils made,.various' means may be employed As shown, an actuating memberfor' device is provided, and this member ispivoted by a screw 57 to a lug or projection 58 of the bracket 37, the said lug forming an extension of the horizontally arranged bracket arm 42. The actuating member 56 is sub-v stantially L-shaped in form and has a cam lever or member 59 pivoted thereto as by a screw 60, said lever 59 serving as an adjustable connection between the actuating mem ber and the vibrator. The screw 60,"wh-en the parts are in'their normal position and the ribbon below the printing point, is axially arranged with respect to the pin 45 of the ribbon vibrator. A roller 61 is held on the pin 45 under the. roller 44: and this roller is adapted to move between vertical walls 62 and 63 of the lever 59'. The Walls 62 and 63 may be inclined and are adapted to be adjusted in proper relation to the roller 61, and said walls form substantially a guide or raceway for th roller during the reciprccatory or swinging movement of the lever with the actuating member 56 as will be presently described. The actuating member 56 is adapted to be moved-inward and outward on its pivot screw 57 and in doing so will carry the lever 59 therewith. The lever or adjustable connection 59 is capable of a plurality of adjustments In one adjustment the walls 62 and 63 are sopositioned with respect to the pivot screw 57 that the actuating member with its lever may be moved without moving the ribbon vibrator. If the lever is moved to the position shown in Figs. 4:, 5 and 7, the walls of the lever become cam' surfaces so that by vibrating or swinging the member 56 on its pivot to carry the levertherewith, the said walls will force the roll 61 inward and thereby throw the end-50 of the vibrator with the ribbon upward, and on the return of the member 56 will bring the ribbon held by the vibrator again below the printing point to its normal position, thus positively moving the vibrator in both directions. The vibrator with the rolls 4:4 and 61 is thus held in its movement'between the walls 62 and 63 of the lever or adjustable connection 59 and the slot 43 of the bracket, the walls 62 and 63 being arranged at an angle with respect to the guiding slot 43 of the bracket.

The actuating member or lever 56 is provided with a vertical portion 6 1' which is formed by cutting away a part of said actuating member to provide a slot 65 through" which the end of the lever 59 may be passed. The lever 59 has a finger portion 66 on the outslde of the vertical part 64 of the actuating member 56 and is adapted to engage cam ortions 67 of the part 64: so as to hold said ever 59 in any one of its adjustments. The lever 59 may be of spring steel tending normally to frictionally engage the under surface of the cam portion 67 of the parts 64 and is provided with an enlarged part 68 in which is an opening 69 to adapt any one of a plurality of disks 70 to be readily seen through said opening according to the position of said lever. There are three brator in this case will be moved to present the black portion of the ribbon to the printing point, and when moved over the disk R, a greater movement will be given to the ribbon owing to the greater inclination of the walls 62 and 63 and consequently the cam action thereof. This will present the red portion of the ribbon to the printing point, and when the lever is moved so that the letter S is seen through the opening 69 the walls 62 and 63 will be so positioned with respect to the pivot screw 57 that the said actuating member 56 with its lever or adjustable part may be moved without operating thevibrator and consequently the ribbon will remain inactive and below the printing point to adapt stencils to be made.

The actuating member 56 is provided with a lug 71 and this lug is provided with an opening in which is fastened one end of a spring 72. The spring 72 has its other end fastened to a lug 73 forming a part of the horizontal bracket arm 42. said spring tending normally to force the actuating member 56 to its normal position and to prevent the ribbon vibrator and actuating member from becoming displaced when the carriage and bed are moved to a folded or compact position. The bracket 37 is provided with a forwardly extending arm 74 which is adapted to be engaged by a stop or part 75 carried by the actuating member 56 and which part by engagement with the arm 74 determines the normal position of the .actua'ting member, the said part 75 being may be adjustably and rigidly held to the transverse bar 28 of the rocking frame 25. The device 76 has a bendable arm 80 located at one side of the plate portion 77 and which projects from one end and liesjsubstantially parallel to said portion. A pin 80 extends upwardly from the outer end of the arm 80 and is adapted to enter a slot-81 located in 130* the arm= 82 of the actuating member 56. It will be evident that when the bar 28 is rocked on the depression of any one of the key-levers through the universal bar 18 that such movement will: by reason of the engagement of the pin 80 with the actuating member '56 rock the latter onits pivot and through. said actuating member move its le Ver 59 and thereby cause the several movementslof the ribbon vibrator as already ex plained. It will be further evident that the arm 80 may be bent forward and backward and thereby make the pin 80 register properly with the slot irrespective of any arrangement' of the location of the rocker bar 28 in' relation to the carriage bed plate, it being understood that the pin 80* may be ment and all that is necessary to properly j position the parts in assembling the machine is to adjust and then fix the device 76 in its proper position.

Instead of forming the vibrator with a single slot for the ribbon, the horizontally arranged arm may have a substantially U- shaped end- 82 This end has two upright portions or arms 83 and 84 in each of which is a vertical slot These slots are intersected by short slots through which the ribbon may be threaded. The arms 83 and 84:

are located on opposite sides of the printingv point and support the ribbon at two points instead of one as in Figs. 1 and 2.

From the foregoing, it will be seen that :simple and eflicient mechanism is provided which is adapted to move a ribbon to cover and uncover the printing point and'which is adapted to permit the machine to be used. for making stencils; that the ribbon vibrator is positivelyheld and guided and is positively moved to carry the ribbon both over the printing point and away therefrom; that simple and etticient means is provided wherebyvarious throws of the ribbon may be obtained; and that'simple and efiicient mechanism is provided whichunay be readily made and assembled and which is particularly adapted for machines in which the carriage is foldable into compact relation to another part of the machine.
