TYPEWRIIIN'G 'MACHINE.

Application filed m 14, 1925. Serial No. 43,492.

This invention relates to stencil-card holding-and-typing' devices for typewriting machines, in which a card-holding frame is arranged to reciprocate tangential y to a revoluble platen.

This device is particularly arranged for use in connection with stencil-cards for 'addressing machines which comprise a comparatively-heavy paper or cardboard frame having an opening, across which is stretched a stencil-sheet. It is sometimes desirable-to type some information on the paper-frame, and then withdraw or silence the typing ribbon to write the full name and address on the stencil-sheet directly with the "bare types.

There is disclosed improved means for automatically controlling the ribbon mechanism, so that it may be vibrated in front of 2 the types at certain times, but silenced while the types are striking the stencil-blank.

According to certain features of this invention, the stencil-card is placed in a cardholding frame, tangentiall 1 disposed in front of the platen, and means of a handle the card-holding frame, is lowered to a point to receive-the first lineof tvping at aha upper edge of the paper-frame. ovel me anism is effective at this position of the card to vibrate the ribbon, and conseqently a lineis typed upon the frame of the card.

QBy means of the usual line-spacing mechanism, the card may beline-spaced several lines during the typing of other lines upon the card-frame,with the aid of the ribbon.

The card-controlling handle is then swung, and by means of a novel stop-device the handle is arrested in a position corresponding to the first line of typing upon the 40 stencil-sheet. During the swinging of the handle to raise the card, the ribbon-vibratmg mechanism is silenced, and automatically the machine is converted into a stencil-cutter. By means of the line-spacing mechanism, the card may again be linespaced in the regular way as fresh lines of typing are cut into the stencil-sheet.

' In order to permit the line-spacing of the card while cutting into the stencil sheet, the

stop-device, designed to arrest the handle in a position corresponding to the first'line of typing on the stencil-sheet; is automatically withdrawn as the handle is released,

thereby making it possible to move the handle further to the rear as the cardis line-spaced.

From the foregoing, it will be seen that the card is handled with a minimum eflort on the part of the o erative, who need not shift the ribbon-mec anism, which is automatically thrown into operation when needed and silenced when not required.

Owingto the comparatively long cards used in this type of machine, and to the desirability of presenting the card to the platen in a fiat condition, it is contrived to lower the card in an inclined path tangential to the platen. This clears the type-bar segment, which is placed below the platen and in line therewith. The printing point is, in this invention, considerably below the plane of the platen-axis, as usual heretofore. To vibrate the ribbon in front of the inclined card, in a path parallel thereto, novel mechanism is provided.

In order to eliminate the blurring of the typing, which would occur if the type-barheads were caused to bear upon the work sheet, and also to improve the return s eed of the type-bars, there is usually provided an anvil against which the type-bars strike previously to striking the work-sheet, the printing upon the sheet being caused by the resiliency of the type-bars. In order that this feature may be maintained both while typing upon the stencil-frame and upon the stencil-sheet, novel mechanism is provided whereby the anvil may be adjusted slightly towards and away from the platen. difference in thickness between the 'cardframe and the stencil-sheet is automatically compensated for by the position of the cardframe.

When cutting the stencil-sheet, it is desir able to provide a backing for the card to both protect the types and facilitate the cutting of the stencil-sheet. Novel means are rovided to automatically present the backmg to the stencil-sheet only, the platen being rotated while line-spacing the card. In this manner, owing to the positive gear connec-- tion between the platen and the card-frame, and, due to the standardization of the cards, the stencil-sheet therein at all times corresponds to the same portion of'the platen, which is-covered with a celluloid strip fastened to the platen by means of a clamping member,--so built into the platen as to. pre- The I sent an unobstructed platen-surface, and thus permit the feeding of the cards up and down as the platen is rotated. in a path tangential thereto. Indrder to facilitate the reading of the typed matter upon the stencil-sheet, there may be provided inking means wrapped around the celluloid strip and fastened to the platen with the celluloid by means of the same holding device.

Other features and advantages will hereinafter appear.

This invention is illustrated as applied to an Underwood standard typewriting machine and is particularly suited for the handling of of cards, such as used in some addressing machines. In Figure 25 there is shown a stencil-card consisting of a heavy paper or cardboard frame having an appendage at the top thereof, upon which it is desired to type several lines 11 for the purpose of identifying, or otherwise relating to the addresses typed upon a stencilsheet 12, stretched across an opening 13 in the lower part of the card, the typing 14 on the stencil-sheet being, of course, desirable to be typed with the bare type, so as to cut into the sheet, thus providing a passage for the ink.

According to the method of handling the card 10, the same is inserted in a recess in side frames 16, behind plates 17 and is lowered all the way down against a stop-bar 18, which forms an integral part of the side frames 16 comprising the cardholdin 'frame. The position of the card after being inserted in the card-holding frame is illustrated in Figure 1.

The card-holding frame is then lowered to the position shown in Figure 4, for the purpose of writing the first line of typing at the top of the card. In order to quickly and positively lower the card to printing position, there is provided novel mechanism including a handle 19 operatively connected to a sector 20 geared at 21, and engaging with a pinion 22. The pinion 22 is fast to a platen-shaft 23, which carries, fast thereto, a platen 24 and a pair of gears 25, l

.in turn meshing with racks 26, forming an wardly, the sector will also be swung, and consequently the card will be lowered.

As it one of the mainfeatures of this invention that the ribbon-vibrating mechanism shall be automatically controlled by the-movement of the card in a manner to afford the rising of the ribbon in front of the types at each key-depression, there is provided mechanism which is operatively connected to a universal bar 27. In order to more fully comprehend the operation of the ribbon-vibrating mechanism, first the action of the ty )e-bars will be described.

Upon depressing each key (not shown), a key-lever 28 is swung on a fulcrum-shaft 29 against the action of a. spring 30, and, by inc-ans of a pin 31 engaging with-a slot in an. intermediate lever 32, the latter is also swung on a pivot The lever 32 is provided at the upper end thereof with a pin 34 engaging a slot in atype-bar 35, whereupon, upon depressing the key, the type-bar is swung on a supportin pin 36. thus striking the card by means 0 a type 37. In order to letterspace the carriage after each type-impression, there is provided mechanism comprising a'pair of dogs 38, engaging with an escapement-wheel 39, which, in turn, engages, by means of a pinion 40 and a rack 41, with the carriage. The dogs 38 are controlled by the universal bar 27 which is bent downwardly at 42 and then rea-rwardly at 43, and again upwardly at 44, forming a pocket 45 for the card. The universal bar is supported in the regular manner upon a supporting member 46 sliding in the typebar segment 47 and upon a rocking arm 48 at the rear of the machine. It will be understood that upon swinging each type-bar, the universal bar is moved to the rear, because each type-bar is provided with a heel 5O striking .a curvate sector 51, which forms an integral part of said universal bar, which is ope5rg-tively connected to the escapement-dogs at Normally, in a typewriting machine, the

universal bar is operated back and forth at each key-depression. In the present matit) chine, a ribbon 53 is held silent in its normal position below theprinting point, as shown in Figure 1. However, upon lowering the card-holding frame and immediately after the stencil-sheet passes the printing field, the ribbon is operatively connected to a round pin 54 fast to a bracket 55, forming a part of the universal bar. Novel mechanism is provided in this invention for the purpose "of connecting the ribbon-mechanism to the universal bar when the paper-frame of the card is in the printing field, and for silencing the ribbon while the stencil-sheet is in the printing field. As it is proposed to switch the ribbon-mechanism automatically,

mechanism is also provided which, in one ,fgrm 'of this invention, comprises a cross-bar 56 fast to the stop-bar 18 of the card-holding frame, and a rotatably mounted plate 58 having two teeth 59 and 60'engaging with connected to said plate 58 at 62, is drawn up,

thus rocking-an arm 63 to which the link 61 isconnected at 64. The arm 63 is fast to a shaft 65"rotatably mounted in a bushing 66 fast toa supporting bracket 67. At. the other side of the bushing 66, the shaft is provided with a head 68 forming an integral part thereof, into which head a shoulder-stud 69 is screwed eccentrically with the shaft, and upon which screw a ribbon-controlling arm 70 is rotatably mounted. Said arm 70 is fast to a'bushing 71, which carries at the other side thereof, also fast thereto, an upwardlyextdnding arm 72, having an open slot 73'at the endthereof, designed to engage the pin 54 in the universal bar. According to this arrangement, the arm 70 forms substantially 'an integral part of the arm 72, so that, when the latter is engaged with the pin, and the universal bar is moved, then both arms are rocked on their supporting stud 69, thereby lifting the ribbon in front of the types by means of a link 74 operatively connected to the arm 70 at 7 5. In order that the slot 73 in the arm 7 2 may be in a position to engage the pin 54 when urged upwardly by the link 61, the arm 70 is provided with a locating finger ,76 at the end thereof, normally resting on a rib 77 of the machine-frame, which is generally indicated by the numeral '78. When the arm 72 is raised, the pin 54, while entering the slot 73, acts as a cam and swings the arms 70 and 72 slightly counterclockwise and raises the finger 76 a short distance from the rib 77, as shown in Figiire 4.

Owing to the design of the card-holder which is caused to be moved up and down in aninclined'path in front of the platen, it is necessary to vibrate the ribbon in front of the card also in an inclined path parallel thereto. To this end, there is provided mechanism which comprises a guiding member 79 fast to the type-bar segment 47 by means of screws80, and a ribbon-vibrator 81 provided with fingers 82 to guide the ribbon. The ribbon-vibrator is operatively connected to the link 74 at 83, the lower end of the link being connected to the arm '70 and allied mechanism in the manner hereinbefore disclosed.

Mechanism is provided to positively hold the ribbon in either its'efi'ective or ineffective to co-operate with a tooth 87:,on .the plate 58,'and, owing to the resiliencyfofthe arm actuated by a spring 88, when the plate 58 is rotated-by the action of the bar 56, it will be held in place by the force of the roller actuating upon either side of the tooth 87. However, such mechanism would "require the spring 88 to be comparatively strong, thereby rendering the operation of the handle hard, or else the mechanism would be unreliable. In order to render the timing of the ribbon-mechanism more positive, there is provided a locking member 89, rockably mounted on a shaft 90 journaled in the bracket 67. Said locking member is provided with a tooth 91, engaging with notches 92 by means of a spring 89 in a disk 93 fast to a. shaft 94. Referring to' Figure 9, it will be noted that the locking member is controlled by a cam-finger 95 fast on the shaft 94 against which finger the bar 56 actuates to swing the locking member, thus withdrawing the tooth 91 from engagement with the notches 92 previously to strik ing either of the teeth 59 or 60, to rotate the plate 58 and to render the ribbon effective to vibrate.

Having written one or more lines of typing upon the paper-frame of the card, the handle 19 is then swung to the rear to move the card upwardly in a position to receive the first line of typing upon the stencilshect. In order to quickly position the card, and at the same time permit its being linespaced by means of the line-spacing mechanism 96, the handle is rotatably mounted upon a stud 97, fast to one of the side plates 98, and is provided witha pawl 99 pivotally mounted on a stud 100 fast to the handle so that the rear rim portion of the pawl may engage the sector 20 upon movement of the handle clockwise. Due to the peculiar manner in which the handle is connected to the sector 20, the same may be rotated counterclockwise a small amount be fore a tab 101, forming an integral part of the handle, strikes the sector, thereby driving the sector therewith. In order to bring the tab 101 in contact with the sector, however, the tension of a spring 102 normally tending to separate the tab from the sector must be overcome, and, in so doing, the pawl 99, which is normally held in the position shown in Figure 4 by the sector bearing upon a heel 103 of the pawl, is permitted to swing to the position shown in Figure 9. in which position it is held by the action of a spring 101, thereby striking a tab 105 of a stop-device 106, the tab extending through an opening 107 in one of the plates 98, thus arresting the swing of the handle and of the card. Upon releasing the handle, the spring 102 is allowed to retract, thereby swinging the handle rearwardly to separate the tab 101 from the sector, and consequently forcing the swinging of the pawl 99 to its normal position, thereby clearing the tab 105 of the stop-devicaand consequently permitting the line-feedin of the platen by means 01': the line-spacing mechanism. In order to accurately position the stencil-card to receive the first line of typing upon the stencil-sheet, the stop-device 106 is rockably mounted upon the stud 97 by means of a screw 108, and is scttable upon the plate after being adjusted by means of screws 109 through circular slots 110 in the stop-device 106. It will be noted that there is provided a similar stop-device 111 having a tab 112 for the purpose of interposing the sector 20 at 113, as shown in Figure 4, thereby locating the card for its lowermost position. The tab 112 protrudes through an opening 114, which is adjustably mounted on the screw 108 and is settable by means of screws 115 through a circular slot 116.

It. will be understood that, upon raising the card-holding frame from its lowermost position to a position to receive typing upon the tencil-sheet. the bar 56 strikes the tooth 59 of the plate 58, thereby disconnecting the ribbon'vibrator from its operating pin 54: in the universal bar, thus permitting the typing of one or more lines upon the stencilsheet with the bare type.

Owing to the positive gearing, connecting the card-holding frame with the platen, a certain portion of the periphery of the platen corresponds with the opening in the card across which the stencil-sheet stretched. This condition is taken advantage of, in this invention, to provide a celluloid strip 117 for the types fixed upon a portion of the platen 24 and wrapped therearound. Novel means are provided for holding the strip, and, if desired, an inking medium associated therewith. The holding means may comprise a longitudinal groove 118 out into the platen, into which groove a bent edge 119 of the strip is placed, as shown in Figure 10. Then the platen is rotated to expose the other bent edge 120 of the strip, as shown in Figure 11, whereupon the edge 120 is forced into a roove 122 behind an eccentric bar 121, whlch is subsequently rotated to the position shown in Figure 12, thereby binding the ed e against the side of the groove 122. Mec anismis provided to rotate the eccentric bar 121, which comprises an operating plate 123 fulcrumed in the platen-axle 23, and operated therearound by means of a finger-piece 125. The plate is provided with a pin 126, engaging with a slot in an arm 127, fast to the bar 121 at vthe end thereof.

In order to compensate for the difference in thickness between the card-frame and the stencil-sheet, there is provided mechanism automatically controlled by the shaft 94, which is, in turn, controlled by the position of the card. It is well known that the Underwood typewriting machine is provided with an anvil against which all the type-bars strike previously to striking the work-sheet, which is struck because of the resiliency of the type-bars. The amount that the type-bars are caused to bend in order to a strike the sheet is so small that if the bars were adjusted by the thick cardboard frame of the cards, then the type-bars would not strike the stencil-sheet. In order to eliminate this condition, an anvil 128 is provided adjustably mounted on the type-bar segment in a manner to afford its bein built u when typing upon the card, an decrease when typing upon the stencil-sheet. F or the purpose specified, a stop-ring or pad 129 is partly milled off in an, angle with a vertical plane through the axis of the platen, and the anvil 128 is slidably mounted thereon. The anvil is also milled in an angle but opposite to the milled angular face 0 thepad'129,'in such a manner that the outer,

face of the anvil will be substantially parallel to the axis of the platen. It is obvious that by sliding the anvil upon the pad the outer surface will be moved either forward- 1y1 or rearwardly depending in the direction t e anvil is swung upon its supporting pad, against which it is held by means of studs 130 fast to the anvil as shown at 131 in Figure 17. The studs extend outwardly through slots 132 in the type-bar segment and are provided with a spring 133 held in place by a collar 134 fast to the studs, I

the spring actuating upon the segment through a washer 135, thus holding the anvil in contact with the supporting pad.

- The segment is automatically swung in a path determined by the curvature of the slots 132 to positions corresponding to the position of the card, thereby compensating for the different thicknesses thereof, and, to this end, there is provided a lever 136 fulcrumed at 137 upon a fixed bracket 138, one end of the lever being provided with a fork 139 designed to engage a pin 140 fast to the anvil 128. At the other end, the lever 136 is provided with a pin 141 through Y which the lever 136 is rocked to change the position of the anvil. Said pin 141 is operated by a link 142 which is in turn operati-vely connected to the shaft 94 through an arm 143 fast thereto and a. pin 144 fast to the arm and engaging the lower end of the link 142.

Sometimes it is desirable to use cards having a comparatively thin paper-frame. such as is illustrated. in Figure 21. In such cases, a suitable card-holding frame may be substituted and the compensating mechanism be not used because the difference in thickness between the paper-frame and the trated in Figures 22, 23 and 24, novel means are shown for switching and locking the ribbon mechanism. Instead of the switching and locking means described at the beginning of this specification, the mechanism comprises a Geneva lock, that is to say, a plate 145 having a notch 146 engaging with a tooth 147 on the card-holding frame. Upon moving the card-holding frame the tooth 147 will be caused to engage with the notch 146, thereby swinging a shaft 148, upon which the plate 145 is secured, from a position shown in Figure 22 to that shown in Figure 23. Said plate 145 is provided with two flat portions 149 against which the side of the card-holding frame slides, thereby preventing the shaft from swinging to its original position unless it is urged by the tooth 147. In order to relieve the plate 145 of the weight of the ribbonmechanismwhich may tend, under certain conditions, to bind and to interfere with the free operation of the card-holdingframe, there may be provided an arm-androller arrangement 150 engaging with a tooth 151 in a plate 58* which is fixed relatively to the carriage. The shaft 148 is rotatably mounted on the plates 98 and moves therewith, being positioned thereon by means of a nut 152 and a washer 153. The plate.145 is fast to the shaft 148 in order to have it, at all times, in engagement with the tooth 147, but the plate 145, being operatively connected to the ribbon-mechanism which is stationary, must also be stationary. To this end, the shaft 148 is provided with a longitudinal groove 154 engaging with a pin 155 driven into a collar 156 which forms. an integral part of the plate 58. The plate 58 is held stationary between a head 157 of the collar 156 at one side of the ears 158 and a hub 159 forming an integral art of said plate. In this manher, .when t e carriage is moved to letterspace the card, the shaft and the plate are moved therewith, the rotating connection being maintained between the shaft and the stationary piece 58 by means of the pin 155 engaging with the groove 154 in the shaft- 148. I

According to another form of this invention, the'card-positioning means are modified to provide a more positive adjustment therefor. Referring to Figures 26, 27 and 28,

in which this modification is illustrated, it

will be noted that there is provided a stop device 160 for limiting the lowermost posi tion of the card-holding frame and a separate stop device 161 for positioning the card for the first line of typing upon the stencilmounted at one side of the plate 98, and is provided with a bent tab 167 protruding through a hole 168 in the plate 98. When the handle 19 is moved rearwardly, as shown in Figure 27, to drive the sector 20 by means of an extension 169, a spring 170, which normally holds the extension 169 awa from the sector, is stretched as shown in igure 86, thereby forcing the pawl 99 out of engagement with the tab 167, to permitline feeding of the plate after being sitluned tor the first line of typing upon t e stencllsheet. In order to facilitate the adjustment of the eccentric studs 164, each is provided with a nick 171 for receiving a wrench, to rotate the stud and then to permanently lo cate it by either driving a pin m the plate 98 or by upsetting some metal into the inch by means of a chisel. v

The modification hereinbefore described is illustrated in connection with means for adjusting the position of the platen relative- 1y to the rinting point. To this end, there are providbd a plurality of brackets 172 fast to the carriage 173 and screws 174 for approximately positioning the plates 98 upon said brackets. The screws are slightly tight ened and the frames are ta ped to position, whereupon screws 175 hol 'ng the brackets to the carriage are loosened and the plates 98 are doweled to the brackets at 176. It will be understood that the holes 177 throu h which the screws 174 are passed, are consiferably larger than the body part thereof, thus permitting the adjustment of the plates preparatory to their being doweled t0 the brackets. It will be understood that in another form of this invention the adjustable feature hereinbefore described is eliminated, and, then, the side plates-98 are directly fastened to the carriage by means of screws 182 through holes 183 in bent portions 184 of the plates 98.

As it is desirable to use a standard Underwood typewritin machine, and to rebuild as little as possib e for embodyin the stencil device in the machine, the she protrudes through the frame of the machine to the outside thereof, and, in order to provide a bearing for the shaft at a point where the frame is cut away to clear the carriage of the machine, there is provided a plate 17 8 fast to the frame'by means of screws 179. For the same reason specified, there is provided the bracket 138 fast to the frame by means of screws 181,. said bracketbein rovided for the purpose of car in the t d 137 upon which the lever 1 3 i% rockably mounted.

Sometimes, comparatively thin cards are used, and then, owing to the small difl'erence in thickness between the card and the stenciLsheet, the mechanism hereinbefore described may be omitted, the typebars being neaaear flexible enough to take care of'the difierence in the thickness and still deliver a clear impression of the types.

Variations may be resorted to within the scope of the invention, and portions of the im rovements may be used without others.
