UNITED STATES PATENT OFFICE.
CHARLES HELLSTROM, F HARTFORD, CONNECTICUT, ASSIGNDR T0 UNDERWOOD TYRE- WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
. TYPE-WRITING MACHINE.
Specification of Letters Patent. Patented Sept. 20, 1910.
Application filed January 22, 1908. Serial No. 412,119.
imityof the guides to each other, the writing To all whom "it may concern:
Be it known that I, CHARLELIIELLSTROM,
a citizen of the United'states, residing in Hartford, in the county .of ,Hartford and I State of Connecticut, have invented certain new and useful Im rovements in Type- Writing Machines, of which the following is a specification.
This invention relates to the paper feed can he carried close to either side edge of the card, since when the card moves to the right or left pasteithr guide, the other guideholds the card against the platen, while the- 'flarmg 11p enables the firstguide to regain control of the card at the opposite movement' of the platen. I also provide a pair of rolls to run upon theplaten immediately ing devices of writing machines, particuabove the tops of the guides, to control the larly to those of the-front strike variety, in card after it has advanced beyond the'usual which a ribbon is vibrated up and down to pressure rolls, so that writing may be concover the rinting pointjat the type strokes. tinned l'l llt down to the bottomedge of the Much diiliculty has been experienced in card. Tliese rolls are adjustable lndepend- 15 guiding stiff cards around the cylindrical ently of each other along the platen. A key platen, because the cards tend constantly to is moun P I .tlle pl t n frame and C 11- bulge out from the platen and to catch in nocted to the rolls to release them, the conthe ribbon, and also to catch upon the type struction being such that the rolls w ll stand aide. Moreover, it has been found usually away from the platen withoutfurther attenimpracticable to write upon the card near tion from the operator, so that the leading its topand bottom edges, which are .found edge of the advanclng card may pass" beespeclally liable to stand away from the tween the rolls and the platen; whereu on,- platen, and which hence are not properly the key may be lifted to restore the rol svto supported or backed to receive the type active positions, and the rolls then serve .to l blows. I hold, the card smoothly against the platen,
The object of the present invention is to.
I ing to be done. along its top and bottom ed es.
yimprovements areillustrated as appliedto an Uriderwood front strike writing machine, in which a cylindrical platen is revolubly mounted upon a platen frame, the latter supported upon a traveling carriage. I mount upon the framework of the machine two card guides, each consisting of a thin yielding plate and extending upin contiguity to the platen well beyond the printing line on the platen, one on each side of the ribbon vibratorand close thereto, so as to hold firmly againstthe platen all portions of the card which are in the immediate vicinity of the printing point at anytime. These guides hold both top and bottom edges close against the platen, so that the card is well supported'and may be written along both its'top and bottom edges. Each of the card guides also has on each of its sides a forwardly flaringlip adapted to turn the .side edge of. the card toward the platen as the latter moves longitudinally, so that liability of the edge of thecard catching upon parts seen at Fig. 1.
and to advance the same after ithas ad mounted underthe platen.
In the accompanying drawings, Figure 1 is a sectional side elevation of. a. platen frame of an Underwood typewriting machine, showing my improvements applied thereto. Fig. 2 is a perspective view of a card guide. Fig. 3 is a front elevation of manner in which a roll-releasing key is held in depressed or abnormal position. Fig. 5 iso fragmentary view similar to Fig. l, but showing the card holding rolls as swung slightly away from the platen, to form a temporary guard or guide for the card as it is inserted in the machine. Fig. 6 is a plan to illustrate the positions of the card guides backof the usual ink ribbon.
Types 1 strike through a ribbon 2 upon the front side of a platen 3', which-is journaled by'means of an axle 4 in the ends 5 Fig. 4 illustrates theof a platen frame, which comprises a paper shelf 6. A gage 7 for the side ed e of the card is attached to the paper shelf 6. ;The card 8 is'carr'ied around the under side of the platen by theusual rear and front pressure rolls '9 and 10. As it advances up the w front sides of the platen, it passes under the -control '.Of arpair-of. guides 11, which are attached at their lower ends. by means of 1 screws 12 to a type bar segment 13, and ex tend upwardly and rearwardly to form with the platen a directrix'for the leading edge of the card, The card guides extend up beyond the writing or printing line on the platen, Fig. 3, and bear yieldingly against,
the front of the platen and hold the card firmly thereagainst. These guides are very close to the usual vibrator 2 which carries the ribbon 2, so that the leading edge of the card may not catch that portion :of the ribbon which stretches across the back of the vibrator, the guides being sulficiently v close tothe platento 'press the leading edge of thecard back from the ribbon. Each of the guides has flaring lips 14, 15, upon its sides to directthe side edge-of the card toward the platen, so that the platen can riage (a portionof which is seen at 16) may be run ackwardand forward freely; Each guide 'is close to the Vibrator 2%, so that whenthe cardhas advanced past one guide, it is held by the other, andthus writing may be carried. close to the sideedges'of the card,
. Each'guide is also-provided with an'upa wardly extending fia-ring'lip 17. "Eachguide'ltis provided with an apertureor eye 18; preferably rectangular, and extending fo'r nearly the entire widthof the guide; The'low'er edge 19 of each eye is coincidentor in register with the printing line on the-platen-, and both: said lower edges taken togethermayibemade-to do duty as.
a scale toenablethe operator to uare'the -'leading'edge-of the card to the wri ing line,
a pair of rolls 21 and the platen 3, Fig. ,5,
said rolls havingbeen 'cast'oif by means of a key 22'. The latter'is mounted upon'one thumhscrewsQS. which pass down through bases 26- secured to said vokcs, and seated end of 'a rock shaft23 journaled at'i'ts ends in yokes- 2st, the 'latter detachably' secured upon the-platen frame-ends by means of upon the topsof the-side bars of th platen frame; A'long the lIlDClBP'SlC lG of the rock shaftei ends a groove 27, in which fit-rolls or'k'e 8' -guirl-e(l* 1n slots 29 formed'rn the arms?of the'voke2i. Itow-s rim-s30 "ress' the ro'l'l si' 28 into the groove, and thereby hold theirock shaftin normal position'with th'eK-key 22 elevated,"li iga' l. -VVhenithe key* is "depressed; tothe Fig. 5 "position, the 1 1folls 28=-are forced out of the groove 27 "and" press uponthe cylindricalperiphery of the produce an: objectionable permanent set or edge coincides with the printing line, said 'edge of the card" from catching upon the 125; form off-a plate having-an eye whose lower rock shaft, and are hence incapable of tIIIH- ing the latter, so that the rolls 21 stand away from theplaten without the necessity, of the aerator holding down-the key v The pressure rolls'21 are supported upon thejrockshaftby means of yokes 31 similar to 24. and having keys 32 pressed by springs Y into the groove 27, so that the yokes and rolls 21 are compelled to swing with. the rock shaft. w Either yoke. 31 maybe slid alongthe shaft independently 'of the other, orv swung up '-independently as indicated in dotted lines at Figg 5. The pres sure of each roll 21" against theplaten 3' may be independently*regulated by means of a thumb screw 3 tthreadedithrough an ear 35,that is, attachedby screws-361w I the crossbar of the yoke .311 Said screw presses against a yielding ar1n*37, Wh0 6 lower end carries the roll 3 21:," and whose upper end is bent at 38 and clamps between the ear 35 and the yoke 31;
In moving from the'printinglline, the card goes directly behindthe rock-shaftj23, which is'right over the front of the platen, so thatthere is no necessity to flex the card unduly around the top of the platen, which would tend to make its bottom edge b1'11ge'-;' out at the printingpoint, and would usually 1 curve in the card itself. 1 i v,
