Specification of Letters Patent.

Patented Oct. 8, 1912.

Application filed February 20, 1911: Serial No. 609,612.

To all whom 2'2 may concern:

Be it known that I, Mourns ll. Poet, a citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in TypeJVriting Machines, of which the following is a specification.

My invention'relates to ribbon mechanisms for typewriting machines and one of its objects is to provide a key controlled throw-varying device, for varying the widthwi'se portion of the ribbon presented to the types by the ribbon throwing or v1- brating mechanism, in combination with a strmwarying mechanism controlled by a key separate and distinct from the key for vary ing the throw.

Another object of the invention is to so combine the key controlled stop-and-throwvarying IllCCllftIl'lSIDS that the throw-wirying mechanism cannot be re-sct by its key in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims. v y

While my invention may be adapted to various styles of writing machines, the pre ferred embodiment of the invention is shown herein in connection with a No. 10 Remington visible tyliewriting machine, Figure 1 being a side elevation of said machine cmb'odymg my invention, partsbeing omitted and parts broken away; Fig. 2, a fragmentary perspective view, taken from the rear, of the ribbon mechanism; Fig. 3, a rear view of v part of the ribbon mechanism taken in vertical section; Fig. 4, a vertical sectional view taken tn :1 plane represented by the line III-wit in Fig. 3 and looking toward the right; and Fi s. 5 and 6, perspective views of a modifiet construction of ribbon vibrator.

As appears from Fig. 1, the main frame of the machine comprlses a base 1, corner posts 2 and atop plate/3, and supports printing instrumentalities comprising type bars at pivoted on hangers o secured to a verti -al stationary segmental support (3, each type bar, being connected through a link 7, lever 8 and link 9 with a key lever 10 having a fulcrum 11 and a restoring spring 12. The type bars are segment-ally arranged and c0- operate with the front face of a rotary platen 13 supported on a vertical shifting platen frame l-Ll. connected by links 15 to a carriage lruck'lti which coiipe 'ates through anti-friction rolls 1'? with fixed trackways 18 above the top plate The platen carrier or carriage comprising the truck and platen frame is impelled leftward by a carriage power or spring drum 19 with which it is connected by a-band 20. Leftward step-bystep movements of the carria e are controlled by escapement devices (hot shown) which are connected by a link 21 with a crank arm 22 on a rock shaft 23 provided near its ends with crank arms 24 from which are suspended by links or arms 25 a. universal bar 26 underlying the set of key levers l0 and being operative thereby. The platen and platen frame are adapted to be shifted on the truck through a shift rod 27 which provides a track for a roller 28 mounted on the platen frame. The shift rod is connected .at its ends by vertical arms 29 with a shift frame bar 30 having at its ends depending arms 31, pivoted to shift key levers (not shown), said levers.operating to shift the frame comprising the bar 30, rail 27 and uprights 29 upward and downward to shift the platen and platen frame correspondingly.

Vertically disposed ribbon spools of which the left-harul one is shown and designated as 32, are arranged below and forward hf the platen, each ribbon spool being mountedon a shaft 713 which carries a beveled gear 34:, said gear being, connected with the spring drum by a train of mechanism comprisim intermeshing beveled gear wheels 37 an 38. The driving shaft/36 is shiftable endwise to bring one or another of the pinions 35 into mesh with its cooperating beveled gear 2-H, thus alternately conncetingthe ribbon spools with the driving shaft. and revcrsing the direction of longitudinal feed of the ribbon. I

The ribbon designated by the nmeral 3.) wound on the spools 22 and guided upward, inward and rearward toward the printingpoint. \Vhile a single-color ribbon may be employed, my invention. is especially applicable to ribbons having printing fields of different characteristics, and accordingly the, ribbon 39 is such a ribbon, it being divided lon itudinally into printing fields a and b of dlfferent characteristics, as

v 6 colors. Opposite the printing point the ribor members 43 and 44, the member 43being pivotally connected to the'vibrator at 45 and .15 being itself pivoted at 46 to-the lever part 44, which is fulcrumed at 47 on a fulcrum bracket 48 on the frame plate 42. The lever parts 43 and 44. are maintained in normal relationship by devices comprising a lever 49' fulcru'med at 47 co-axially with the 52 fixed at 53 to the shift bar 30. "The norlever part. 44. The lever 49 is connected through a link 50 with the tail 43 of the lever 43 and the opposite armof said lever 49 is pivotally connected at 51 with an arm mal lower case position of the lever parts is illustrated in Fig. 2. At printing operation the two lever parts are operated as a single member without substantial change of relationship; but when the platen is szshifted it operates through the arm 52, lever 49 and link50 to alter the normal relation-- ship of the lever parts 43 and 44, the part 43 turning on the pivot'46to'lift the vi,-

brator and ribbon to a new normal position corresponding with thefshifted position of the platen. From its. shifted position'the lever part 43 will again be operated as before, together with the lever part 44 at 40 printing operation. During the shifting movements of the lever part 43 due to the platen shift the lever part 44 will remain unaffected," Theseparts 43 and 44,-although in themselveslevers, have. been designated 45 aslever parts since together they are comprised in the operating lever as a whole, which operating lever is fulcrumed at 47, is connected at 45 to the vibrator and is connected at'.the.opposite side of. the fulcrum' to actuating devices which comprise a stud 54 engaging in a slot 55 in the lever part 44, said stud being fixed to the upper endof an actuating. link 56 off-set rearwardly as indicated at 56 to an arm 58 on 55 the rock shaft 23. It will be understood that at printing operation the universal bar 26 is actuated, rocking the shaft 23 and I vibratin the link 56, said link in turn actuating he operating lever 43-, 44 which vi- 60 brates the vibrator 40 and raises and lowers the ribbonfirst tocover the printing point toreceive the type impression and then to lower the ribbon to expose the imprint on the paper."

The stud 54 is settable at different points ,lengthwise of the slot 55to vary' the extent part by a screw 60 on the bracket 48. The

shift frame 59 is formed with a downward extension 59 provided with a slot 61 in which the stud 54 en ages. The tail or extension 59 of the shi t frame is offset rearward and extended laterally, being pivotally connected at 62 with a lever fulcrumed at 64 on a bracket 65 screwed or otherwise securedto the periphery of the type bar segment. The off-set arm of the lever 63 is pivot-ally connected at 66 with a crank arm 67 secured to the rear end of a rock shaft 68,'said rock shaft hearing at its rear end 'in an extension of the bracket 65 and extehding forward to a bracket 69 supported on the left-hand front corner post 2, said shaft bearing on and projectin through said bracket 69 and being provide at its forward end with a knurled finger button 70 by which the shaft maybe rocked back'and forth. The rotary movements of the shaft operate through the crank arm 67 and lever 63 to slide the shift frame 59 back and forth. When the shift frame is slid inward from the Fig. 2 position it will operate to shift and re-set the stud 54 and link 56 so that they will operate nearer the fulcrum 47 of the, operating lever. The result is that at printing operation a greater extent of throw is communicated to the operating lever and the ribbon vibrator is lifted to a greater height presenting the lower ribbon field b to the action of the types. The ribbon throw-varying mechanism above described is that withwhich the machine has heretofore been provided.

In carrying out my invention 1 provide novel stop (lGXLliIQS for the vibrator actuatmg mechanism, said stop devices beihg con trolled by a key or finger piece separate from and independent of the finger piece or key 70 which controls the throw-varying means. The novel stop devices, as herein shown, com-prise a stop member 71 which is pinned at 72 to a rock shaft 73 and is provided with two radial projections which terminate'in stop faces 74 and 75, the stop face 74 being at avgreater distance from the axis of rotation of 'the shaft 73 than is the stop face 75: The stop faces are ad'a ted to cooperate with the bottom face 0 0. lug 76 formed at. the rear end of the lever part 44.

The rock sha-ft 73 extends leftward, termipart 80 with stop extensions 80 and 80.

The part 80 is engageable with V- notches 81 and 82 formed in a collar 83 fixed to the rock shaft 73 to the right of the stationary I tent spring to ride out of the notch 81 and bearing bracket 7 8.-

When the detent 80 is engaged with the.

notch 81 as shown in Fig. 2, the stop face 74 is uppermost and in the path of the coacting stop 76 on the lever part 44. This relation of the stop faces corresponds with the arrangement of the throw-varying niechj I anism shownin Fig. 2 wherein the stud 54 is located to give the operating lever the shorter of its two predetermined extents of vibrating movement. The height of 'the stop face 74 is such that the stop 76 will contact with it to arrest the ribbon throw 0r vibrating mechanism when said mechanism'j has raised the ribbon high enough to pre sent the ribbon field ato the type. The co acting stops 74 and 75 will operate to prevent overthrow of the ribbon and will insure that the printing is confined to the. ribbon field a.

Since the throw-varying and stop varying devices are controlled by separate and "independent keys or hand d vice's there is a possibility that the operator, when resetting or readjusting the throw -varyi'ng mechanism might orget to correspondingly readjust or reset the stop mechanism. To guard against this possibility I provide check devices which prevent the r'e-adjustment of the throw-varying mechanism until the stop mechanism has been itself reset. The check devices constitute means for insuring that the independent throw varying and stop mechanism shall be set and reset in a predetermined order; that is, the stop mechanism shall be reset first and the throw varying mechanism last. In the present instance the check or reventive devices comprise an arm 84 fixed t0 and rising from the rock shaft 73 and having a rearwardly bent extensiol'i or stop proper 85 which lies in the path of movement of the upper arm of-the lever 63 so that the lever cannot be turned on its fulcrum in the course of resetting the rheck 85 has been swung out of the way, the

only manner of accomplishing this being by w g, irning the rock shaft 73 to reset the-stop mechanism. For instance, in the Fig.2 posit-ion of the parts wherein both the vibratring mechanism and the stop mechanism are set to provide for the'proper movement and arrest in printing position of the ribbon field a, the stop 85 is at the left of the lever 63 viewed from the rear ofthe machine an into the notch 82, the V 8O passing slightly beyond the point of said notch and engaging with the lower portion of the rear incllncd face thereof. It will be understood that the rock shaft 73 will thus be put under a slight tension which tends to turn it oppositely from the arrow-in Fig. 2. Consequently if new the stud 54 be re-adjusted nearer the fulcrum 47 (as shown in Fig. 3)v by turning the finger button 70, the lever 63 will be swung across past the rear end of the stop 85, as shown in Fig. 3, and said stop will thereafter turn backward slightly until the spring-V, seats itself in the bottom of the notch 82. This slight backward turning movement re-se'ts the stop 85 in the path of the lever 63 but at the opposite side of said lever, as will be understood from a consideration of Figs. 3 and 4. The engagement of the spring detent with the notch 82 maintains the rock shaft 73 in its new or reset position in which position the stop face 75 is set in the path of the stop 76 so that it will arrest the operating lever 43, 44

when it has been given its greater extent of throw by the I'e-set actuating stud 54.

When the vibrating mechanism is arrested by the engagement of the stop 7 6 with the stop 75, the ribbon field b will be opposi print-in point and the stops will pr said ribbon field from being overthrown past the printing point. a

It will be seen that when set in the position shown in Figs. 3 and 4, the stop 85 will prevent the resetting of the vibrating mechanism in the Fig). 2 position since the lever 63 will be locked y the stop 85 against swinging back from the Fig. 3 to the Fig. 2 position. Consequently as a pre-requisite to resetting the vibrating mechanism for the upper ribbon field a, it will be necessary to re-set the stop 'mechanism by turning the rock shaft forward slightly to permit the lever 63 to swing pastit when'the finger button 70 is turned, and thereafter to turn the rock shaft 73 rearward until arrested by the contact of the rear face of the collar 83 with the stop 80". By these operations the stop mechanism will be re-set m the Fig- 3 position and the throw-varyinginechanism also resetin said position.

It will be observed that the key or finger button 70 is at the front of the machine and the key or finger button'77 is at the left-hand side of the machine, so that these keys or' buttons may be conveniently manipulatedconcurrently by the operator, one key with one hand and one with the other, although they areseparate and independent. Thus it will be seen that the advantages of a simultaneous manipulation of throw-varying or stop devices are retained while the difficulties heretofore encountered in practice of successfully adjusting the parts of interdependentthrow-varying and stop devices to give corresponding and accurate results are obviated.

The vibrator heretofore described has the tops of the ribbon receiving slots closed and possibility of the ribbon beingthere is no thrown out ofthe vibrator, but there are times when the printing portion of the ribbon is thrown higher than it should be between said slots. In order to provide for more perfect control ofv the printing portion of the ribbon devices may be employed of the character shown in Figs. 5 and 6. Fig. 6 illustrates a vibrator designated as a whole as 86 and provided with parallel up right portions 87 which terminate at their tops in spring forks 88, said forks providing closures at their tops for vertical slots 89'. The slots are adapted to receive a ribbon frame 90 (shown in Fig. 5). Said ribbon frame is preferably formed of a single piece of sheet metal'which inc'loses the ribbon in a narrow frame having: an opening 91 through which the types maystrike. The

frame is provided witlrforwardly. extendingangular ears .92 which are adapted to fit in the slots 89 in the vibrator,- being snapped into place by forcing them down between the spring forks 89, saidjforks having beveled upper edges and the lower faces of said forks which form the tops ofthe slots 89 being also slightly beveled to facilitate the removal of the frame from the vibrator VYhen. in place the frame holds theprinting portion of. the ribbon accuratelyzini tion on the vibrator andso that theribbon passes behind the upper parts of the uprights 87. Preferably, as a matter of convenience, a sheet metal frame .90 may be provided with each ribbon, being arranged on the outer free end of the ribbon so that v when the same is to be employed in the ma chine, the ribbon frame may be. readily snapped into place on the vibrator. The ribbon .frame prevents the accidental displacement of the ribbon on the vibrator and also prevents the upward displacement of the printing portion of the ribbon due to the momentum imparted to the vibrator at printing operation.
