TYPEWRITING MACHINE.

Application filed August 5, 1921. Serial No. 489,880.

To all 20720171716 may concern:

Be it known that I, BURNHAM C. Srrox- NEY, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification. I

This invention relates to'mechanism of the continuous billing or so-called fan-fold type, such as shown in the patent to VVernery & Smith, No. 1,132,055, granted March 16, 1915, and is herein disclosed as applied to a bookkeeping machine of the Underwood- Hanson type;

Heretofore, it has been impracticable to use a carbon-carrier and other features of the continuous billing or fan-fold type of mechanism on the bookkeeping machine .of the type referred to, since the denominationselecting mechanism at the rear of the lastmentioned machine necessitates the positioning of the extension or track for the carhon-carrier at such a height above the normal position of the platen that the latter cannot be lifted suiiiciently by the usual mechanism to enable sufficient straightening of the web to permit the withdrawal by the carbon-carrier of'the' carbon-sheets attached thereto. Further difiiculties also arose due to the fact that the forward end of the track would interfere with the adjustment of the denomination-selector at different positions along the carriage and also with the positioning of the tabulator-stops It will be evident that .the diflioulty found in adjusting the tabulator stops on the bookkeeping machine equipped with fan-fold mechanism also exists in the usual typewriting machine of the continuous billing or fan-fold type.

According to one form of the invention, the excessive bending of the webs over the guide at the front end of the track located above the denomination-selecting mechanism is substantially avoided, by supporting the carriage extension or track in an inclined position. It willbe seen that by giving the track a suitable inclination, the bend in the Webs over the forward end of the track may be sufliciently diminished or even eliminated in straightening the webs when the platen is in raised position.

In order to render the back of the bookkeeping machine accessible for adjusting the 1 and hold it in raised selector-dogs and tabulator-stops, the fanfold extension or track is supported on a rear rail so that it may be swung about the same to raise the forward end of the exten sion from engagement with the rear of the carriage on which it normally rests. To limit the upward movement of the extension position, when desired, provision may be made of suitable means, such as a togglelevice, which may be utilized to hold the extension in raised position, the to 'gle being collapsible to enable the return or the extension to its normal position.

Due to the normal inclination of the carhon-carrier and the variation in such inclination in swinging the trackabout the rear rail, the carrier tends to slide along the track. To prevent such accidental movement of the carbon-carrier, provision may be made of suitable braking means which, while permitting manual movement of the carrier, will prevent accidental movement.

Usually the rail on which the rear of the carbon-carrier track travels is supported by a frame connected to the back of the typewriter frame and resting directly on the same surface as the typewriter. Inasmuch as the typewriter of the bookkeeping machine rests upon the computer casing and the latter is usually mounted on a stand, it is impracticable to support the rear rail in the usual manner, since the top of the computer casing is only' of sufficient size to receive the frame of the typewriter proper. It has been found advantageous, therefore, to support the rear rail for the carbon-carrier extension upon brackets secured to the rear of the typewriter frame.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a diagrammatic side view showing the carbon-carrier positioned at the rear and the platen in position to receive typing thereon.

Figure 2 is a plan view of the structure shown in Figure 1.

Figure 3 is a view similiar to Figure 1 but with'the platen raised and the web straightened, the track for the carbon-carrier being shown in raised position in dotand-dash lines.

Upon depression of the keys (not shown) of a typewriter forming part of a bookltee ing machine of the Underwood-Hanson type,

j a cylindrical platen 13, mounted on an axle 1'4journaled in a carriage 15, which is supported for sliding movement transversely of the typewriter by means including a rear rail 16 fixed on the typewriter frame 17. Each type-bar in its effective movement actuates the usual escapement mechanism (not shown) and effects a letter-feeding movement of the carriage.

As is usualin' bookkeeping machines of the type referred to the frame 17 of the typewriter is set on the casing 18 of the computing mechanism, and provision is made of means whereby the letter-feeding movement'of the carriage will effect denomination-selecting for the computing mechanism. To this end, provision is made of brackets 19 extending rcarwardly from the type writer carriage and of rods 20 and 21 car- 'ried thereby. Rotatably and slidably mounted on the rod 20 is a denominationselector 22, which may be held in proper letter-space positions therealong by means of a tooth 23 engaging notches in the rod 21, the selector 22 normally lying in de pressed or ineffective position. Obviously, a lurality of selectors may be used.

pon a letter-feeding movement of the carriage into a computing zone determined by one of the selectors, a frusto-conical roller 24 on the rear end of the selector 22 will ride up on the conical end of a roller 25, having a cylindrical portion of substantially, the length. of the computing zone, and cause a tappet 26 on the selector to engage seriatim the forward ends of jacks 27 of a certain set, to advance seriatim the usual pin'barsby connections (not shown). Provision is made of the usual jack-housing 28 and the usual housing 29 for thethrust-rods (not'shown), by which the movements of the jacks 2'7 are transmitted'to the computing mechanism, the housing 2-9 being connected to the jack-housing 28 at its forward end by any suitable means, such as ears 30, and the jacks and jack-housing being supported on the typewriter frame by any suitable means, such as a bar 29? and brackets 29 There maybe several sets of jacks, and actuation of a set ofjacks by one selector 22 and not'by others may be obtained by arranging the different sets with the forward ends of the jacks extending to different positions toward the front of the machine, and by arranging the tappets 26 on the different selectors 22 in accordance with thesets of jacks to be actuated thereby. The brackets 19 may also be utilized to support a toothed bar 31, on which may be po sitioned, at letter-space intervals, tabulatorstops 32 in position to be engaged by counter-stops 33, when the latter are lifted by means (not shown). The computing mechanism and the denomination-selecting mechanism, forming part thereof, may be, in general, similar to that disclosed in the patent to Richard M. Becker, No. 1,296,355, granted March 4, 1919. Y

Inasmuch as the present invention contemplates the use in a bookkeeping machine of the features of a continuous billing or so-called fan-fold machine, the axle 14 of the platen is journaled in ends 34 of a platen-lifting frame, said ends 34 being pivoted at the front of the platen on a rod 35, and being supported in normal'position by arms 36, forming part thereof and resting on a rod 37, supported on the carriage beneath the upper end of the rear paper table 38. To insure the proper retention of the ends 34 in their normal positions,

provlsion is made of means, including an arm 39, mounted on the rod 37 and having on the frontside thereof a hook 40, to engage over a pin 41 on the adjacent end 34 of the platenlifting frame. The arm 39 may be limited in its forward movement by a lug 42 extending below the rod 37 so to engage a fixed part of the carriage when the arm 39 is in its forward position. Helease of the platen-lifting frame may be effected by swinging the arm 39 to the rear bymeans of a finger-piece43 at its upper end.

Due to the projection of the jack-housing 28 above the platen, it is not feasible to use a horizontal carbon-carrier-track frame, as is usually the case. in continuous billing or fan-fold machines, since the webs or plies 44 would necessarily be bent downwardly over the front end of said. frame or table and upwardly around the platen, even when the platen is in its raised position, and the friction between thewebs and the carbon sheets would be so great that the latter could not be retracted. According to this invention, the carbon-carrier-track or rearward extension 45 of the carriage 15 is mounted, in an inclined position, so that the webs 44, in passing over the track, will be inclined forwardly and downwardly, and pass to the elevated platen without bending down over the front end of the .carbon carriertrack frameor table. It. will be evident that the carbon-sheets may be withdrawn even if the webs cannot beentirely straightened under the platen, the only requisite being that the bends in the webs and interleaved carbons must be reduced sufiiciently to permit slipping of the carbon-sheetsbetween the webs. The plane of the carbon-carr ertrack frame or table may be substantially tangential to the bottom ofthe displaced platen.

The rearward extension 4 Which maybe referred to in general as thecarbon-carriertrack, comprises front and rear. rods 46and 47, respectively, connected by a plurality of.

stepped blocks 53 on which are supported blades 54, to which the carbon-sheets 55 are attached at their rear ends. For convenience in shifting the carbon-carrier on the rails 49, provision is made of a forwardlyextending arm 56 having at its end a fingerpiece 57, which may easily be grasped by the operator and used for shifting the carboncarrier 53. i For reasons which will appear more clearly hereinafter, provision is made of leaf-springs 58 attached to the plate 52 near its forward edge and pressing against the rails 49, so as to resist accidental movement of the carbon-carrier along the track,

To limit the movement of the carbon-carrier along the rails 49, provision may be made of a stop or stops58.

At its rear, the extension 45 is supported by arms 59 depending from the outside rods 48, and each of the arms is provided with a roll 60 having a concave. groove therearound to fit on a rail 61 which serves as a support therefor, engagement of the rail 61 by the rod being insured by an offset portion of each of the arms 59, extending beneath the rail 61' in such a manner as to prevent the lifting of the rolls 60 therefrom. Inasmuch as the typewriter frame 17 is supported by the computer casing 18, it is not feasible to support the rail 61 in the manner usual in continuous billing or fan-fold machines, and it has been found convenient to use brackets 62 attached to the typewriter frame at its back and near the sides thereof by suitable means, such as screws 63.

To support the extension 45 at its front end, suitable brackets 64 are attached to a bar 65 forming part of the carriage, and

these brackets are provided at their upper ends, above the jack-housings, with recesses 66 to receive the reduced end or portions 67 of the front rod 46 of extension 45. It will be seen that the shoulders formed at the ends of the reduced portions 67 engage the inner faces of the brackets, thereby preventing relative movement, transverse to the machine, between. the extension and the typewriter-carriage. One advantage of this arrangement resides in the fact that it permits the front end of the extension 45 to be swung upwardly, thereby making accessible the denominationselecting mechanism normally lying therebeneath. so as to render it convenient to adjust the latter, when necessary. I

To limit the upward movement of the front end of the extension 45 and to detain it in raised position when desired, a link 68 is pivoted at one end to the left-hand end of the rod 46 and also by means of a pivot 68 to one end of a link 69 mounted at its other end on a pivot or screw 7 0 carried by the lefthand bracket 64. Suitable provision may be made for lost motion at the pivot 68 to avoid any interference with the upward swinging of the track 45. Upon lifting the forward end of the extension 45, the link 68, and, consequently, the link 69, will be shifted from the position shown in Figure 1 to theposition shown in FigureB, the link 69 then resting on a stop-pin 7O carried by the left-hand bracket 64. In the normal position of the link 69, a lug 69 forming a prolongation thereof beyond the pivot 76 engages the pin 70 if desired, provision may be made of a hook 71, which, when swung into position, will engage the shaft or rod 46 and prevent accidental displacement of the latter. It willbe obvious that the leaf-springs 58 tend to maintain the carbon-carrier 53 in any position to which it has been moved during the movement of the extension 45 to and from the raised position shown in dot-and-dash lines, Figure 3.

When the machine is to be used, the platen-lifting frame is released by grasping the finger-piece 43 and swinging the arm 39 rearwardly. The lifting frame is then swung about the rod 35 until it assumes the position shown in Figure 3 and the webs 44, which have been passed over the rear rod 47, between the carbon-sheets 55 and over the front rod 46, are led beneath the platen and over a knife 72. The platen is then swung to its normal position to co-operate with feed-rolls 73 and the machine is ready for use. After typing a line on the webs, they may be advanced by operating the usual linespace mechanism, not shown. Such opera tion causes actuation of a gear 74, which, through a broad gear 75, actuates a gear 76 mounted on the end of the platen-axle. The line-spacing action, in printing on a-set of forms such as are usually carried by the webs in use in the continuous billing machine, will advance the forward ends of the webs alonga front paper-table 77, which forms part of the platen-lifting frame, and when the typing of a form has been complet ed, the lifting frame will again be swung to the Figure 3 position, and the leading ends of the webs grasped by the operator and drawn forward into contact with a gage 7 8 secured by a screw 79 at any desired position along a bar 80 forming an extension of the front paper-table 77. The operator, while holding the leading edges of thewebs in gaged position, may grasp the fingerpiece 57 with the other hand, and press the same 'rearwardly to shift the carbon-sheets 55 into position between unused portions of the webs. After restoring the platen to its mounted position and severing the used portions of the webs by drawing the same across the knife 72, typing may be begun on another set of forms on the webs, and the operation described. may be repeated as many times as required.

Inasmuch as the fan-fold mechanism. whose so has just been described, is mounted, as, herein disclosed, on a boohl-ceepin machine of the Underwood Hanson type, typing of digits may be accompanicdby computation in. either one or both of the totalizers (not shown) associated with the two sets of jacks. The selectors 22 maybe adjusted at suitable letter-space positions along the rod 20 by swinging them upwardly to withdraw their teeth 2-3 from the notches in the rod 21 and sliding them along the-rod 20 to the desired positions. hen such settings of the selectors 22 and of the tabulatoustops 32 are to be effected, the carbon--carrier-track 4L5 is moved out of the way by swinging it to the raised position shown in dot-and-dash lines in Figure lVhen such settin s have been made properly the typir 4 t and the correspondingcomputa n ma be effected concomitantly during the passage of the carriage 15 through any computin none determined by a selector Variations may be resorted to within the scope of the invention, and portions of the imlnovements may be used nt others.

A machine for typing upon superposed plies of web, comprising a typewriter frame, a platen, a platen-carriage mounted to travel along said frame, said carriage comprising a frame upon which the platen may be displaced upwardly for straightening out the web to permit the carbons to be shifted between the plies of web, a carboncarrier, a carbon-carrier supporting and guiding table connected to the carriage to travel therewith, the forward end of said table being at the rear of the platen and at a substantially higher elevation than the platen, to clear elevated stationary parts at the rear of the typewriting machine which co-operate with the carriage, as set forth, the .web running forwardly over the carbon-carrier, and bending down around the front of said table and under the platen to feed up in front thereof, said platen when in its elevated position being below the front of said table, and the latter being in clined rearwardly and upwardly from its front end, so that the plane of the inclined table is about tangential to the bottom surface of the platen when in elevatedposition, to permit the web to run off from the table to the bottom of the platen, without being bent down around the front edge of said table, thereby to permit the web to be straightened out sufficiently to permit the shifting of the carbon-sheets between the plies of web, and means to overcome the tendency of the carbon-carrier to slide down along the inclined table. a

27. In a front-strike typewriting machine, a carriage, and a revoluble platen displaceable upwardly in the carriage sufiiciently to straighten out the work-sheets to permit carbons to be shifted back along the web, said machine comprising adding mechanism having parts to co-operate with the carriage, said co-operating parts mounted at the rear of the carriage and above the level of the platen when the latter is in typing position, a carbon-carrier, and a track therefor connected to and extending backwardly from the typewriter carriage, said track being above said adding-machine mechanism, and extending in a direction substantially tangential to the bottom of the platen when the latter is displaced upwardly for so straightening out the work-sheets.
