WHITFIELD HAINER, OF TORONTO, ONTARIO, CANADA.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Dee. `13, 1910.

Application led May 25, 1909. Serial No. 498,207.

To all `whom tt may concern;

Be it known that I, WHITFIELD HAINER, of the city of Toronto, in the county of York and Province of Ontario, Canada, have 1nvented certain new and useful Improvements in Type-Writing Machines and I hereby declare that the following 1s a full, clear, and exact description of the same.

vType writing machines for mamfoldmg purposes are now providedwith` auxiliary Icarriages from which the carbon and the paper for the original and impression copies are intermittently fed in continuous strips from the carbon and paper rolls to the platens of the main carriages. In certain of these machines provision is made for the withdrawal of the carbon from `between Vthe original and impression copies before thewritten part is severed from the unwritten part of the continuous strip or strips, but the means by which this Withdrawalis effected have no provision for correctly and positively returning the free end of the carbon toa fixed `zero position, a necessary provision to prevent the carbon being severed with the paper or withdrawn from an impression position.

One of the features of the present inven tion relates to a means by which the free end of the carbon can be correctly returned to a fixed zero position preferably between the line of severance andthe place where the platen receives the impact of the type and this part of the invention is carried out by providing the shaft of the carbon roll with a pinion meshing`with a spur wheel and revolving in one direction as the carbon is intermittently fed to the platen by the spacing of the lines, and providing the spur wheel with a circumferentially adjustable arm operating an audible alarm when' the spur wheel has completed a revolution or a predetermined lpart of a revolution so that the spur wheel and pinion can then be turned in the opposite'direction for the rewinding of the carbon until the reverse revolution of the spur wheel is arrested by the adjustable arm engaging a fixed stop. It 'is advisable however, before the carbon can be withdrawn from between the original land impression copies,`to provide for the removal of the pressure exerted against the paper by the feed roll and paper lingers, the removal of this pressure bein accomplished by the releasing lever, which when actuated to release the pressure of the feed whereby loose sheets, piled on a support forming part of the auxiliary carriage, may

be fed to the platen by a manually operated feeder, either unitedly with the feeding of the paper strips or independently thereof.

The invention further relates to a means by which an impression copy may be simultaneously made on an envelop of the name and address written on the original copy, this means consisting ofa supplemental carbon roll mounted in the auxiliary carriage and from which the carbon is fed between the platen and the adjacent strip or'sheet/of paper and automatically withdrawn therefrom when the address has been written.

For an understanding of the invention reference is to be had to the following description and to the accompanying drawings in which- Figure 1, is a perspective view of part of a type writing machine showing the main carriage, the auxiliary carriage and the arrangement of the carbon and paper rolls and the manner in which the carbon and paper are fed to the platen of the main carriage. Fig. 2, is 'an end elevation of the construction shown in Fig. 1. Fig. 3, is an end elevation of the platen showing the releasing lever and the means actuated by the releasing lever for removing the pressure of the feed roll and paper fingers from the paper. Fig. 4, is a perspective view ofthe envelop guide attached to the main carriage. Fig. 5, isa perspective view of part of one of the rolls u on which the carbon or paper is woun and Figs. 6 and 7, are diaammatic views showing the osition of t e envelop with respect to the p aten when being inserted, addressed and ejected.

Like characters of reference refer to like parts throughout the specification and drawings.

In the specification the term carbon is used to desi ate carbon paper, carbon cloth, or an simi ar flexible material holding color in so ution or covered with a coating of the same, suitable for making an impression copy of the type written matter wrltten on an underlying sheet.

The strips of paper a and b are continuously fed -to the platen c from the rolls a b mounted in the auxiliary 'crriage cl,

vspur wheel h. The arm j permits of the p-in la being disengaged from and renga'ged with the spur whee connected to and unitedly movable with the main carriage e and mounted in the auxiliary carriage d is a carbon roll f, from which the carbon is fed between the paper strips a and b.' The shaft g of the carbon roll f extends beyond the auxiliary carriage and is provided with a pinion g meshing with the spur Wheel It mounted on a shaft or stud i journaled in the auxiliary carriage d. The shaft or stud 'i projects beyond the outer face of the spur wheel 71. and is provided with a loosely mounted arm j having lateral movement with relation to the slide face of the-spur wheel and rotary movement on the shaft or stud, and projecting from the arm j is a pin lc engaging with the teeth of the ateral movement of the teeth and the rotary movement of the arm permits it to be positioned to engage between any selected teeth. The engagement of the pin k with the teeth of the spur wheel causes the arm to revolve unitedly with the latter so that durin the revolution of the spur wheel in one irection, the lug l projecting from the arm j will actuate', the striking mechanism m of the alarm bell o to .announce the completion of the strip of written matter.- The arm when the spur wheel is revolved in the opposite direction'engages with the projecting end of the shaft g and arrests the revolution of the spur wheel. For convenience the alarm bell o and the striking mechanism m are adjustably connected to and supported by a curved band p attached to the auxiliary carriage adjacent to the sur wheel, the adjustment of the alarm be lpermitting the length of written matter `to` be varied.

In-the use of the device above described, the paper strips a and b are fed from the rolls aand 'b'. to the platen c with the carbon from the carbon roll f between them. When the freeend of the carbon reaches the zero position indicated byl dottedline 2-2 (see Fig. 1) preferably located between the knife gand the place 3 where the platen receives the impact of the type, the

arm j is moved laterally to disengage the pin lc from the teeth of the spur wheel. L and is then turned in the direction indicated by arrow until it engages with the shaft g, the latter forming a fixed stop to arrest the revolution of the arm in that direction, the pin /tbeing then permitted to rengage with the teeth of the spur wheel. The paper strips a and b and the carbon are then intermittently advanced by the spacing of the lines, and the advancement of the carbon causes the revolution of the shaft g and the pinion l g. The pinion g meshing with the spur wheel h causes the latter to revolve in the opposite direction to that indicated by arrow, and carry with it the pin k and the arm j until the lug Z of the "arm engages with the striking mechanism 'mf of the alarm bell, announcing the line where the strip or strips of Written matter are to be severed. The arm j and spur wheel 7b are then turned in the direction indicated by arrow torewind the ,carbon on the roll f and withdraw the carbon .from between. the ori 'nal and impression copies until its free en is returned to the zero position 2 -2. The travel of the arm j and spur wheel h in the direction indicated by arrow is exactly the same as the travel of the arm and spur wheel in the opposite direction, consequently the same quantity of carbon is rewound on the vroll f as isunwound from it by the advancement of the carbon'during the spacing of the lines. The free end of the carl bon is thus returned at each operation of the arm y', to the same zero position which being below the knife g ldoes not come within the line of severance when the written part is being removed from the unwritten 'lli part of the strips a b, consequently no waste j of carbon can occur, vand the carbon is always in position for use forl impression purposes. It is necessary, or at least it .is advisable, to have the length of written matter of uniform size, and it is for this reasonA that tlfe bell is Vactuated by the arm when the spur wheel has completed a revolution or a predetermined part of a revolution, the arm being advanced toward the bell by the revolution of the pinion g and spur wheel h caused bythe advancement of the carbon during the spacing of the lines. To vary the length of the written matter, the bell o is adjustable on the curved band p, and isv provided with a clampr by means of which it canv be locked in any adjusted position thereon. Before the carbon can be conveniently returned to its zero yposition the pressurelof the feed roll s and paper fingers t from the paper should be released, and

' this release is effected in the usual way by the releasing lever u and link o.

The paper fingers t are adjustably connected to a rod t supported by arms w rockable from the shaft `@a mounted in the main carriage e, one of the arms 'w being prolvided with an adjustable lug 1/ engaged by the usual releasing lever'u when operated to remove the pressure of the usual feed roll against the paper. The actuation of the releasing lever u to release the feed roll raises the lug y, the arms fw and rod t the rod t lifting the paper fingers t away from the platen so that they Awill relea e their pressure against the paper. When` the feed roll and paper fingers have been `I/noved out of contact with the paper, the arm j is turned in the\direction indicated by arrow until it engages the'shaft g which arrests its movement in that direction. 'The free end of the carbon is then at the zero position,

vase

feed the loose sheets successively to the "platen, the disk engaging the topmost sheet `only durin its rotation. l

The lauxi iary carriage d is providedV with brackets i. in which is mounted a shaft z" supporting the carbon holder j for envelop -addressing purposes. The carbon holder 1s of a cylindrical character, provided with a slot'k, immediately above the shaft. z" for the passage of the carbon.` Projecting from the carbon holder j', immediately below the slot c is a plate Z, over which the carbon j passes.

Io address an envelop, the paper for the original and impression copies is advanced beyond the platen a distance substantially equal to the width of the envelop as shown in Fig. 6. The envelop is then lnserted between the paper for the last impression copy and the laten and the carbon for addressing t e envelop is inserted between the envelop and the last impression copy. The revolution of the platen is then reversed until the paper and the envelop are restored to the position where the address is to be written, the reversal of the platen reversing with 1t the envelop and the paper for the original and lmpression copies as shown in Fig. 7. The wrlting of the name and address on the `original copy causes an impression to be made upon the envelop by means of ythe carbon v`from the carbon holder j. The advancement of the original paper by the spacing of the lines causes a corresponding advancement of the envelo and when the latter is clear of the platen t e carbon holder 7" turns by gravity and raises theplate Z', lifting the envelop and the carbon for addressing the envelo into a position clear of the platen, and ho ds them in that position until removed from the Atype writing4 the nature of the invention.

vlspring clizp B The carbon holder j is provided with a the plate and preventing it bein unwound from 'the carbon roll within 51e carbon holder except when sufficient vstrain is ap'- lied for that urpose. One end of the caron holder y" 1s open to receive the roll of carbon and the slot c communicates with.

the o en end to lenable the carbon to be intro uced into the holder in a partly unrolled-condition. j

When the envelop is of a length that its end will project beyond the paperstrips a b, the main carriage e may be provided with an envelop iide m such as shown in Fig. 4, and whic is attached to the main carriage as shown in Fig. l, and holds the proj ecting end of the envelop against the laten.

The s ool ends q for the aper rol s a b and cargon roll are provi ed with clips 1" which en age t e shafts s supporting the rolls a b and f, the clips r belng provided with set screws t by'which the cli s are locked to the shafts so that the spoo ends will unitedl revolve therewith when the paper or car on is being rewound upon the spools through the agency of the knobs u.
