Specification of Letters Patent.

Patented Dec. 26, Main.

Application filed October 10, 1912. Serial No. 724,914.

chines, of which the following is a specification.

My invention relates especially to mechanism for differentially feeding work sheets in typewriting machines and for producing a plurality of inked or original typewritten copies and the general object of said invention is to provide improved mechanism of the character specified.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

The embodiment of my invention herein disclosed was particularly designed for waybilling purposes but it will be understood that the principles of said invention may be employed for producing other kinds of typewritten work besides way-bills; also it is to be understood that while I have herein shown my invention as embodied in a Smith Premier No. 10 typewriting machine, said invention may be applied in whole or in part to other styles of typewriting machines. a a

In express company way-billing of the character for which the present form of my invention is especially adapted, it is desirable to produce two copies of each way-bill, one of which is used as a label being pasted on the parcel or package, and the other being a way-bill proper; also an abstract of certain entries on each way-bill for the auditing department, and a complete record of each bill for the home oflice; that is to say, three first or original typewritten copies of the complete series of entries on each bill are needed and in addition a fourth or record copy containing in condensed form abstracts or certain entries only of each bill. Thus ribbon mechanism is necessary for pro? ducing four first copies and also mechanism is needed for feeding threework sheets together and for so controlling the fourth sheet that it is fed differentially or intermittently and is only written upon at predetermined intervals.

In carrying out the invention the work sheets which are preferably continuous are wound on a set of roll carriers which are supported on a support or truck slidably mounted in the rear of the machine and connected to move or slide back and forth with the platen carriage thereof. The platencarriage supports a divided rotary platen composed of two coaxial sections arranged end to end, the left-hand section being associated with paper feeding devices and being employed exclusively as a device or means for feeding or advancing the Work sheets over the right-hand platen section with which cooperates the usual printing instrumentalities. Line spacing devices'are associated with the left-hand platen section and turn the same.at eaclriactuation, said section being connected-with the right-hand platen section by devices including disconnectible pawl and ratchet mechanism in such a way as to cause the right-hand section to be given a a rotary movement at desired predetermined intervals, such rotary movement being in a direction opposite from the line spacing or paper-advancing movement of the left-hand platen section. Concurrently with this backward movement a turning movement is also communicated to a receiving roll carrier for the record sheet aforesaid, said carrier being mounted on the carriage. This record sheet is the innermost sheet of the set of four superposed or overlying work sheets and is narrow so that it does not overlie the left-hand platen section and consequently does not'cooperate with the paper feeding devices associated therewith. The three other work sheets which are so wide as to extend over substantially the full length of the two platen sections are superposed upon the narrow record work sheet. The forward or outside sheets are interleaved with the plies or sections of a special or auxiliary ribbon which is mounted on a platen carriage andis connected to be fed or advanced when the right-hand platen section is turned. The narrow record sheet passes through an opening zor-s lot between shield extending the full length of said section and connected therewith. This sbield;.is

normally in the path of the printing types so that it prevents such types from making impressions on the record sheet. However, when the intermittent backward movement of the right-hand platen section takes place a corresponding backward or downward movement of the typeshield occurs, carrying said shield out of the path of the pr1nt-. ing types and so that when they are actuated their impressions may be made not only on the outermost sheets as theretofore but also von the fourth or narrow record sheet. The parts are arranged so that the shield remains in inoperative position long enough to permit the writing of one line on the record. sheet, said shield being automatically restored to the position in the path of the types at the next actuation of the line spacing mechanism. The outermost sheets may be severed or torn off in sections when completed asdesired, this taking place usually as each way-bill is finished, a severing device being provided for the purpose. The record sheet need be removed from the receiving holder only at long intervals and as may be convenient.

My invention will be described and explained in detail in connection with the accompanying drawings, wherein Figure 1 is a fragmentary .end v1ew partly in section of the upper part of a front-strike Smith Premier a typewritmg machine embodying my invention. Figs. 2 and 3 are fragmentary front elevations showing respectively the right-hand and left-hand end portions 'of the platen and associate parts. Figs. 4 and 5 are vertical sectional-views taken centrally through the platen and showing respectivelythe righthandand left-hand end portions thereof together with associate parts. Fig. 6 is a fragmentary diagrammatlc plan view showing the ribbon spools and gulding devices and illustrating the course of the ribbon in assing from one spool to the other. Flg. g is a sectional view taken transversely of the platen on planes indicated by the broken dotted line mm in Fig. 4 and looking in the direction of the arrows at said line.

Figs. 8 and 9 are perspective views of details of construction, Fig. 8 showing a relatively. fixed cam for disconnecting the pawl and ratchet mechanism and the mounting of said cam, and Fig. .9 showing detent devices associated with the receiving carrier for the record sheet. Fig. 10 is an end view of the pawl and ratchettmechanism comprised in the connection between the lefthand and right-hand platen sections, side; view showing also the cam for disconnecting the pawl and ratchet. Fig. 11 1s a diagrammatic view transverse, of the platen and showing the interleaving of the work sheets and the plies of ribbon. Figs. 12 and 13 are respectively fragmentary face sheets. Fig. 15 shows a rear elevation of said truck. 7

As appears from Figs. 1 and 14 the main frame of the machine comprises end plates 1 and a connecting top plate 2 from which rise standards 3 supporting an inclined grooved track-Way 4 which cooperates through anti-friction rollers 5 with the rear or slide bar 6 of a carriage truck, this truck further including end plates 7. The truck provides a support for a detachable platen frame or carrier proper which comprises end bars or plates 8 and connecting cross rods 9 and 10. J ournaled in the end plates 8 1s a platen, spindle or axle 11. When the platen frame is in place on the truck the axle 11 bears in seats or depressions 12 in the end plate 7 of the truck which thus provides a support for the platen frame and the platen mounted thereon. As thus far described the parts are like those of the No. 10 front-strike Smith Premier machine.

The platen that is supported on the axle 11 is of novel construction and consists of two parts or sections, the details of which are best illustrated in Figs. 4 and 5. The left-hand section consists of a hollow wooden core 13 surrounding the axle 11 and extending substantially throughout the length of the divided platen and further includes a shorter sheath portion 14 surrounding. the left-hand end portion of said core. Secured to the left end of the core 13 by wood screws 13 is a platen head 15, the hub of which receives a set screw 16 that engages the axle 11 and thus maintains the left-hand platen section in rigid relationship with said axle. The right-hand end portion of the. core 13 is slightly reduced and provides a bearing surface for a metal tube or sleeve 17 which serves as the core of the right-hand platen section, said section further comprising a sheath 18 of rub=. her or the like which is suitably secured to the tube 17 between end rings 19 and 20 which are fastened to the tube 17 by screws 21. The two sections being coaxial and of the same diameter present a substantially secured in fixed relationship therewith is" by a pin 27. This pin also serves to secure to the outer face of the annulus and in fixed relationship therewith and with the wheel 22 a ring 28 provided with a series of peripheral gear teeth 29. The annulus 26 comprises a series of stepped faces and its inner end portion fits within the righthand end of the core 13, said annulus being secured to said core by screws 30, thus} fixing the relationship between the left-hand platen section and the line spacing wheel 22 and gear teeth 29.

The line spacing wheel is provided with a fewer number of line spacing teeth 23 than is common, twelve of such teeth'being shown in the present instance. Cooperative with these teeth are line spacing devices of the usual construction com rising a spring pressed plunger 31- (Fig. 1 terminating in a, beveled tooth for cooperation with the teeth 23. Said plunger is seated'in a barrellike hearing 82 that is mounted in an opening 33 in the right-hand end plate 7. A rock shaft/34 bears in said end plategtndis operatively connected to the barrel 3 said rock shaft terminating at the front in a downwardly extending finger piece or line spacing handle 34 which when actuated causes the plunger or pawl member 31, cooperating with the teeth 23, to turn the lefthand platen section through a line spacing distance. A restoring spring 35 is connected with the barrel 32 in the usual way. It will be observed that between the peripheral ridges or teeth 24 are curved depressions 36.

Cooperative with these depressions is a de tent wheel 37 pivoted on a spring arm 38 secured by a screw 39 to the right-hand end plate 8 of the platen frame. The detent 37 fits accurately in and cotiperates with the depressions 36 to maintain the left-hand platen section in predetermined line spacing .positions and to determine finally the extent of the line spacing movements.

Pivotally supported on the frame rod 10 and coiiperative with the left-hand platen section is a paper guide plate 40 (Fig.3) of ordinary construction, said plate providing a mounting for front pressure rolls 41 and rear pressure rolls 42, the two sets of rolls cotiperating with the left-hand platen section only and assisting to advance or line space the paper when the line spacing de vices are actuated. No paper feeding vdevices cooperate directly with the right-hand platen section. the main sheets being advanced over this section while it is motionless, by the cooperation between the feed rollers and the left-hand platen section.

Connected to the right-hand platen section is a shield which is in the form of a strip 43 (Figs. 1, 2 and 7) of very thin sheet metal secured at its ends by screws 44 to the platen rings 19 and 20. The body of the Normally as shown in Fig. 1. the shield is in the path of the types 46 when the type bars 317 carrying. said types swing toward the platen, so that the types will cooperate with the shield and willfail to make an impression on a sheet which may pass through the slot-way 45. 'The term shield is used in a broad sense for means that prevent the cooperation of the types. with the printing face'of the platen itself. Automatic means, are provided for turning the right-hand platen section backward or in reverse direction at predetermined intervals and thus swinging down the shield 43 to an inoperativeposition (Fig. 7) out of the path of the types and so that the types may cooperate directly with the face of the platen and im print on the paper passing through the slot 45. The automatic means for thus actuating the right-hand platen section and the type shield is operated from the left-hand platen section through. the gear 29 secured at the right-hand end of said section. Cooperative with the gear 29 is a somewhat smaller gear 48 mounted loosely on a hub 49 (Fig.

4) of aratchet wheel 50, the hub of said ratchet wheel being fixed by a cross pin 51 to a rock shaft 52 arranged and supported above the right-hand platen section and'eis tending longitudinally thereof. The left-* hand end of said shaft takes hearings in an arm 53 which rises from the frame rod 9 as shown in Fig. 2 and is secured thereto by a cross... pin 54:. The right-hand end of the shaft is supported in an arm or bracket 55 which is secured by a cross pin 56 to said rod. The details of the bracketpiece 55 are best shown in Fig: 8; Curving forward from the upper portion of the bracket piece is an extension 57 terminating'in a head 58. The inner face of this head is formed with cam devices comprising two cam edges 59, a connecting circular face or dwell 6G and a circular face 61 of lesser diameter connecting the inner ends of the cam edges 59.

Inward from the cam. devices is a boss 62 and the entire head is formed with a central hole 63 in which the hub 49 takes a bearing as shown in Fig. 4-, the rock shaft 52 being thus supported through said hub.

1 Mounted loosely on the shaft between the arm 53 and the ratchet 50 is a receiving roll carrier or spool 64 secured to the righthand end of which is a ratchet wheel 65 like the ratchet wheel 50 and contiguous to the same (Figs. 1, 2, 4, 7, 9 and 10). The left-hand end portion of the carrier G l is formed with a polygonal or hexagonal head 66 with which cooperates at diametrically opposite faces a double detent spring 67 secured to the rod 9 by a screw 68 (Fig. 9), these devices serving to hold the roll carrier in predetermined positions after it has been turned for winding the paper thereon. Fixed to the outer reduced end of the shaft 52 by set screws 69 is the hub portion 70 of a crank arm 71 having its forward end offset inwardly. Said forward end carries a depending adjustable link 72 and as best shown in Fig. 7 said link is pivotally connected with the right-hand platen section by a shouldered screw 7 3 which is secured in the ring 20. The right-hand platen section is .thus connected with the shaft 52 through the link and the crank arm. The gear wheel 48 servesiprimarily' as a pawl carrier and actuator having pivotally secured to its inner face at 74 a forwardly extending pawl 75, the engaging end or tooth of said pawl being in the plane of the ratchets 50 and 65 and being broad enough to cooperate with both of said ratchets. A spring 76 constantly presses said pawl toward said ratchets but the pawl is controlled by the cam faces heretofore described through a lateral pin 77 which extends rightward from the pawl 75, near its free end, through a hole 78 in the gear wheel 48 so that it may engage saidcam devices. When the pin 77 rests on the circular face 60 as shown in Fig. 10 it is held out of operation; but when the pawl is in engagement with the face 61 as shown in Fig. 7 it is operative on the ratchet wheels. It will be understood that once during each rotation of the gear wheel 48 under the actuation of the left-hand platen section the-pawl will be rotated to a point where the pin 77, sliding over the face or edge 60, will engage the rear cam edge 59 and that then thepawl spring 76' will force the pawl into engagement with the cooperative ratchet wheel so that during the next turning movement communicated to the gear wheel 48 the pawl will operate on the ratchets to turn the roll carrier 64 and to rotate the right-hand platen section and the shield 43 to the position shown in Fig. 7. This figureshows the parts at the end of the movement communicated by the pawl 75, and it will be observed that the pin 77 is contiguous to the forward cam edge 59 so that at the. next actuation of the gear wheel 48, said cam edge acting on the pin, will lift the pawl out of operation and cause the pin to engage with the dwell face 60 as shown in Fig. 10. When the ratchet wheel is thus freed from the pawl the right-hand platen section and the shield 43 will be returned to the normal position of Fig. 1 by automatic means comprising a restoring spring 79 connected at its forward end to a screw 80 on the right-hand platen section and at its rear end to a screw 81 on the arm 55. A stop pin or device 20 on the ring I 20 cooperates with the cross rdd 9 as shown in Fig. 1 to limit the return movement of the right-hand platen section. The stop pin .20 moves away from the stop device or rod 9 to the position shown in Fig. 7 when the platen section and shield 43 are turned to abnormal position. It will be observed that the spring 79 constitutes means tending constantly to turn the right-hand platen or platen section in one direction, while means are provided comprising the line spacing handle 34 which acts through the left-hand platen section to overcome the spring 79 and turns the right-hand platen in the opposite direction. It will be understood that while the right-hand platen section is thus turned against the spring 79 once during each complete rotation of the gear wheel 48, the number of such turning movements may be increased or decreased as desired and in accordance with the work in hand. In the present instance it is desired to write on the record sheet once only during the filling in of a way-bill and therefore only one actuat ing pawl 75 is employed, or from another point of view, only one cam is provided to cooperate with the single pawl.

As heretofore stated the work sheets, four sheets of which are shown and numbered 82, 83, 84 and 85, are preferably in roll form as shown in Figs. 14 and 15 and are supported independently of the platen carriage by means which per 86 are not my invention. The rolls of paper are arranged one above the other and are supported on rotary spindles or carriers 86 which are mounted on an upright rectangular frame 87, said frame being secured to a movable truck 88 which is connected by ball bearings 89 with a fixed" track-way 90. Said track-way in turn is secured to brackets 91 which rise from a shelf 92 fixed at the rear of the table or support 93 on which the typewriting machine rests. Horizontally disposed arms 94 pivotally connect the frame 87 to the platen carriage and cause the traveling roll support comprising the frame 87 and truck-88 to travel back and forth with the carriage. The construction is such that the weight of the rolled work sheets and their supporting devices is taken off the carriage, thus conducing to a lighter and easier'running thereof. The work sheets are led or drawn upward from the rear with their respective rolls and over guide rods 95 and 96 on the traveling frame 87 and thence forward over the usual paper table 97 and around the platen. The three outer sheets 82. 83 and 84 are substantially of the full width of the platen and at their right-hand end portions are in the control of the paper feeding devices' 41 and 42; while the innermost sheet 85, which is the narrow record sheet, passes around the right-hand platen section only so that it is not controlled by said paper feeding devices. Said record sheet 85is led around the platen. and upward under and to the rear of the roll receiving carrier 64,

bill comprises a series of lines to be filled in,-

' label and the other for an office copy they suitable devices.

its free end being secured to said carrier by As herein shown in Fig. 4, said devices may comprise a longitudinal groove 98 in the body of the carrier and a cotiperating pivoted clamping bar 99 for forcing the paper into the groove and clamping it to the carrier.

Figs, 12 and 13 show respectively fragmentary portions of thg way-bill proper, which may be the sheet 83, and the record sheet 85. The way-bill comprises a series of printed blanks as shown, one blank following another and being separated by perforations 100 to facilitate tearing off from the roll after being 'filled in or printed; The right-hand portion of the bill to the right of the dividing line 101 is filled in on the typewriti ng, machine while the left-hand portion is divided into spaces which are to be stamped at transfer offices. It will be observed that the right-hand portion of the seven of such lines being shown in the present instance, although the number may be varied. These lines are preferably a line space distance apart so that after filling in the blanks in one line an actuation of the line spacing handle 34 will advance the next line to position to be filled in. All of the data in each of the lines is written on the three outer sheets 82, 83 and 84, although since one of these sheets is to be usedfor a need not necessarily be printed in blank as at the left of the dividing line 101 but only need bear the printing at the right of said line. The inner sheet 85 which isto go to the auditors'ofiice only requires the data on the first line of each way-bill to be reproduced; that is, the No, the Date, the Town or City, the Express Charges and To Whom Paid.

Preferably each of the four work sheets is printed directly from an inking ribbon so as to obtain a first copy and to this end spe cial inking mechanism is provided, mounted on the platen frame or carrier. Referring especially to Figs. 2,3, 5 and 6 it will be seen that said mechanism comprises a pair of ribbon spools 102 arranged side by side at the left-hand side of the platen and co-axially therewith. The platen axle 11 extends beyond the left-hand end plate 7 and has fitting over it and secured to it by a screw 103 an extension 104 on which the spools 102 are loosely mounted, each spool bearing on a reduced portion 105 of said extension and being confined between the shoulder formed by said reduced portion at one end and a disk'106 secured to the opposite face thereof. Beyond the left -hand spool the extension 104 is further reduced at 107 and fixed on this reduced portion is a finger wheel 108 of the usual style, a corresponding finger wheel being secured at the opposite end of the axle 11. The spools 102 are spaced some distance apart and in the space between them is arranged a connecting member or lever 109, this lever being pivoted at 110 in a slot or kerf 111 in the extension 104,

One end of the lever 109 is provided with oppositely disposed teeth 112 which are adapted for alternate cooperation with sets of circularly arranged teeth or projections 113 struck from the inner flanges 'of the spools 102. The opposite end of the lever 109 is providedwith a friction spring 114 which is engageable with the opposite faces of the inner flanges of the spools 102. A detent spring 115 cooperates with the lever 109 to maintain it in engagement with one or the other set of teeth 113. When engaged with a tooth of one set the member 109 connects the associate spool with the axle 11 so that said spool will turn with said axle and with the left-hand platen section so as to wind the ribbon on said spool. Simultaneously the ribbon is unwound from the other spool which is at this time loose on-the extension 104 but is prevented from turning too freely by the engagement of the friction spring 114 with its inner surface. Secured to the left-hand end bar 8 of the platen frame by a screw 116 is a guide bracket 117 which is off-set'forward and extends leftward transversely of the spools, being provided with an integral arm 118 which bears on the axle 11 and assists to maintain the bracket in proper position on the platen frame. Said bracket is provided on its outer face opposite the spools 102 with diagonal turning bars 119. The right-hand end portion of the bra'cket is provided with four vertically disposed and parallel guiding devicesor bars numbered respectively 120, 120 120 and 120, these guiding devices projecting different extents from the face of-the guide 117. At the opposite end of the platen there is secured to the end bar 8 a forwardly extending arm 121 which supallel upright arms or bars 122. The ribbon 123 is led off from the left-hand spool and under the bracket 1'17, thence over the associate turning bar 119 and inward along the front or printing face of the platen, passing through and under the adjacent turning bar 119 as well as under all of-the vertical guiding devices or bars. At the right-hand end of the platen the ribbon passes around the rearmost arm 122 and thence is reversed, being directed back toward the left along the platen, then around the guiding device 120 and rightward again along the platen, then around the forward of the two upright arms 122 and leftward again along the platen,

passing under the guiding device 120" and course of the ribbon is directed at right an-v gles to its former course and passing around and under the bracket 117 is directed to the other or: right-hand spool 102. It will be seen that by this arrangement four parallel thicknesses or plies of transfer media or ink ribbon are provided extending along the front or printing face of the platen. Preferably the front ply of the ribbon is threaded through the usual ribbon vibrator 124, said vibrator, shown in Figs. 1 and 2 being pivotally supported on an arm 125 fixed to a rock shaft 126 which is pivoted to the upper part of the machine frame and is operative from the printing keys by connections comprising a crank arm 127 extending rearward from the rock shaft 126 and a downwardly extending link 128 connected to said arm 127. Normally the vibrator maintains the outer ribbon ply down below the printing point p as shown in Fig. 2 so that any writing which may be on the work sheet immediately underlying the outer ply, in the present instance the work sheet.82, will be exposed as soon as printed. It is to be understood, of course, that the number of ribbon plies will vary with the number of work sheets printed and that, instead of the outer ply being controlled by the vibrator, said vibrator may receive the regular ribbon of the machine so that with the supplementary ribbon 123 arranged in four plies as described, five first copies may be taken. However, the arrangement illustrated is preferred for the character of work now under consideration. In Fig. 11 isdiagrammatically illustrated the relationship of the four work sheets 82, 83,84 and 85 with the interleaved plies of theribbon 111. It will be observed that the record sheet is next to the platen and passes between it and the shield 43 ,said shield normally covering the prints ing point on the work sheet 85, the first ply of the ribbon which is intended to coiiperate with the work sheet 85 being forward of the shield and contiguous thereto. The ribbon plies alternate with the work sheets and the forward ribbon ply is normally loweredbe-o low the printing point by rason of being within thecontrol of the vibrator, as is clear from Fig. 11. The record sheet 85 winds on.

the receiving roll holder 64 while the three outer sheets pass above said roll holder and if not torn off will be directed rearward and may cooperate with a guide rod 129 on the frame 87 To assist in tearing off the sections of the written way-bills or work sheets, a severing device or blade 130 is arranged lengthwise of the platen above the printing line, said blade being secured by screws 131 to the end bars 8 of the platen frame. The

front upper portion of the blade is preferably beveled to provide a sharp cutting edge and as illustrated in Fig.2 thisibeveled portion may be provided with a scale or indicat- ,Assuming that the first line of one of the way-bills is opposite the printing point and that the parts are in the position illustrated in Fig. 7 with the shield 43 lowered, then each type actuation will cause an impression to be made through the ribbon plies on each of the four associate sheets so that when the various items in the first line of the waybill have been printed as indicated at 133 by 02 marks in Fig. 12, said line will also be reproduced on each of the other wide sheets 82 and 84 and also on the narrow record sheet 85. This record sheet may, if desired, be printed in like formcorresponding with the printing in the first line of the waybill, or as shown in Fig. 13 it may be a plain sheet not containing any printed blanks. After the first line 133 has been printed, an actuation of the line spacing handle 34 will, through thecoiiperation of the feed rollers 41 and 42 with the left hand platen section. not only advance the three outer sheets but will also, through gears 29 and 48, advance the pawl 75 and cause the pin 77, acting against the forward cam edge 59, to lift the pawl out of operation, said pawl moving idly to the Fig. 10

77 sliding over the dwell or face 60. Assuming thatthe last line of the way-bill has been printed and that'the pin will have moved to the dotted line position indicated at-77 in Fig. 10, then at the next actuation of the line spacing handle to advance to the first line of the next succeeding way-bill, said pin will drop down, the rear cam edge 59 allowing the pawl to engage with the teeth of the ratchet wheels 50 and 65, turning said ratchets and through them the roll holder 64 and the rock shaft 52. The turning of the roll holder causes a single line spacing movement of the record sheet 85 and presents a fresh part thereof opposite the printing line; while the turning of the rock shaft 52 operatesthrough the crank arm 71 and the connecting link to turn the right-hand platen'section and lower the shield 43, so that if now the types are actuated the first line of the next bill sheet will be'printed and will be reproduced not only on the three outersheets but also on the underlying sheet 85 as indicated at 133 (Fig. 13). The operations above outlined are repeated each time a way-bill is printed so that for each printing of the entire set of way-bill blanks there is a single line written on the record sheet 85. It will be understood that during the entire series of line spacing operations for printing the lines making up a way-bill. the record sheet will advance but once, this advance preferably taking place during the movement of the last line of one Way-bill to the first line of the next succeeding Way-bill. During the other line spacing movements of the way-bill the righthand platen section and the shield will remain motionless and the three outer Work sheets will be advanced over said right-hand platen section by the paper feeding devices at the left-hand end thereof without affecting the latter. Also it Will be seen that during the backward movement of the righthand platen section as described the record sheet 84 will be moving forward and wind ing on the receiving carrier 64.

My present invention provides for doing away with the writing of way-bills by hand in booklets as heretofore and for greatly facilitating the speed of writing and the legibility of the work.

Various changes may be made in the in-- vention and parts used without other parts, all without departing from said invention.

\Vhat I claim asnew and desire to secure by Letters Patent. is

1.
