TYPE-WRITING MACHINE.

maniac.

To all whom it may concern:

Be it known that I, HERBERT H. STEELE, citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Typell*"1'itin--' Macl'lines, of which the following is a spi ification.

My invention relates especially to ribbon mechanism for typewriting machines and its general object is to provide improved devices of the class 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.

In certain classes of typewritten records, for example in some system of railway billing, it is necessary to provide for as many as twelve or fourteen copies of the work.

Ordinarily this duplication of copies is accomplished by the emp-loyement of carbon inlays between the work sheets, and this method has been found to be satisfactory in cases where the entire writing on the pack of paper, comprising the alternate work sheets and carbon inlays, is to be completed at one time and withoutthe pack being re moved from the machine until the work is done. There are, however, other forms of multiple record work in which the pack of work sheets and inlays must be removed and re-entered a number of times in the machine before the record on said sheet-s has been completed. Heretofore it has been customary in such cases to bind the pack together by fasteners or clips in order to prevent displacement of any of the sheets during re moval and entering. This is objectionable, however, as consuming considerable time, first, in adjusting the carbon inlays between the work, sheets; secondly, in binding the pack and, thirdly, in removing the carbon inlays from between the finished records. Furthermore, if the sheets are largeand the paper thin, the trouble experienced in maintaining even an approximately regular and uniform alinement in the undermostsheets of the pack is very great. On the other hand, it has not hitherto been possible to provide a typewriter inking ribbon which is capable of delivering sufficient ink to a work sheet when the latter printed to enable said work sheet to reproduce its lin Specification of Letters Patent. Application filed December 31, 1909.

{ pressions on as many as twelve or fourteen tissue sheets in a copying press. Six or seven good reproductions seem to be about the limit of the inking ribbon, whereas a pen written copy or master sheet is capable of reproducing as many as twelve or fourteen copies in the copying press.

To overcome the disadvantages of the typewriter work in respect of the number of copies which may be reproduced therefrom, it is contemplated in the present-instance to provide a supplemental ribbon at the rear face of the work sheet sa th-at the impact of the types will be reproduced on the front of said sheet from a main copying ink ribbon which is mounted and fed in the usual way while simultaneously the rear face of the work sheet will receive the type impressions from the supplemental ribbon. It will be apparent that-the negative impressions on the will be in register with the positive impressions on the front face thereof. Thus the printed characters will be visible on each side of the sheet and each side of the sheet will have sufficient ink to penetrate six or seven tissue copies so that it is only necessary to place the typewritten work sheet or master sheet in the middle of a pile of twelve or fourteen tissue sheets and take copies thereon by means of a copying press operated in the ordinary way.

In carrying out my invention in the presentinstance I provide an inked web or ribbon sheet having a width substantially equal to the printing field of the way bill orwork sheet. This web is wound upon spools which are contained within a hollow casing or drum having the. same diameter as the regular cylindrical platen of the machine which said drum replaces. The drum also contains an anvil or platen face-which cooperates with the types through a slit or opening extending longitudinally of the hollow casing. Each ribbon spool is geared to a shaft which. extends through the hollow casing and corresponds with the usual platen shaft, being controlled for line spac ng by pawl and ratchet mechanism. Hand operated devices for changing the direction of the ribbon feed are provided, and associated with these devices are automatic means for -be actuated. Saidautomatic means com- I prises an abutment which s adapted to coindicating when the reversing devices should rear face of the work sheet operate with the paper table to prevent the insertion of a fresh work sheet prior to the actuation of theribbon reversing mechanism. The work sheet is fed around the hollow casing by feed rollers of the usual or any suitable type which cooperate with rotary casing sections contiguous to the ends of the main stationary casing. The slot or opening in the stationary casing through which the types strike is only wide enough ,to afford clearance for the types so that only a small'amount of the auxiliary ribbon is exposed. The feeding devices for said auxiliary ribbon are adjusted to operate at each line spacing operation so as to advance said auxiliary ribbon a distance corresponding substantially to the width of a line of writing.

Thedetails of my preferred construction will be more clearly understood from a consideration of the accompanying drawings which show one form of the invention applied to a Monarch typewriting machine and wherein,

Figure l a transverse sectional view of the upper part of a Monarch typewriting machine embodying my invention. Fig. 2 is a transverse section taken on a plane rep- .rescnted by the dotted line :0 in Fig. 6 and looking in the direction of the arrow at said line. Fig. 3 is a transverse sectional view on a plane represented by the dotted line 1 in Fig. 6 and looking in the direction of the arrow at said line. Fig. 4 is a front elevation of the hollow casing or drum and associate parts. Fig. 5 is a fragmentary horizontal sectional view taken centrally of the hollow casing, some oi the parts shown in Fig. 4 being omitted. Fig. (5 is a fragmentary vcrtiral sectional view taken centrally of the hollow casing.

Referring first to big. 1., a top plate 1 of the machine supports standards to which are secured grooved guide rails 3 in which are se ted anti-friction balls at. Said balls cooperate with longitudinal grooves formed at the top and bottom of a rear or slide bar 5, said bar being comprised in a platen frame or carrier oi? the long platen style, and which further incl udcs end bars (3. The end bars (3 provide bearings for an axle or shaft 7 like the usual platen shaft, said shaft 7 being provided at its ends with finger wheels 8.

Through intermediate devices hereinafter described the shaft 7 provides bearings for two disks or heads 9 which are spaced apart a'distance somewhat greater than the length of the lines of writing of the work for which the structure is intended. Secured at its ends to these disks 9 is a cylindrical hollow casing or drum 10, the diameter of which corresponds to that of the usual rotary platen whose position in .the machine said casingoccupics as clearly appears from Fig. 1, which is a sectional view taken about; midway of the length of the casing 10. The casing proper extends from a oint below the printing point at the front 0 the machine in a downward, rearward and upward clrcular curve terminating under the usual paper fingerrod 11 which is supported'on the end bars 6 and rovidcs an anchor for the easing. Stays in the form of sheet metal hooks 12 are arranged at intervals along the rod 11 as shown in Fig. 4, said hooks partly surrounding said rod and having rearwardand downward extending portions 12 which are riveted or otherwise secured to the casing 10 and hold the same from turning relatively to the axle 7 The rod 11 also provides bear-. ings for the hinges 13 of a cover plate 14, the hinges being secured to said cover, plate as by rivets 15, the cover plate thereby being adapted to be swung on the rod 11 as a pivot. The rear end of the cover plate abuts against the end of the casing 10 which underlies the rod 11 and said cover plate is concentric with the casing, being practically a continua-- tion thereof and extending downward to within a short distance of the printing line.

It will be noted more especially from Figs. 1 and 4: that there is a gap or longitudinal slot-way 16 in the casing oppositethe printingpoint, said gap extending between the bottom edge of the cover 14 and the top edge of the front of the casing proper and being of a width slightly in excess of the heights of the type characters. Practically filling the gap widthwise and extending the full length thereof, is an anvil or platen 17 which tapers toward the rear and is provided with clip 18, said clips. engaging the shaft 7 and securing the platen 17 thereto. The body portion of the platen is rounded at its top and bottom edges, but it terminates at its ends in rectangular enlargements 17' which are seated in slots 19 (Fig. 1) formed in the disks 5). These slots prevent rotary movement of the platen about the axle 7. The clips 155 permit the platen to be readily detached and removed from the casing when the cover thereof is lifted but when arranged as shown in Fig. 1 the platen will be station ary with respect to the casing and has only a longiturjlinal movement during the advance and the return of the platen carrier.

A wide ribbon or web 20 impregnated with copying ink and having a width somewhat greater than the length of the printing line is provided, said ribbon is suitably secured at its ends to shafts 21 and 22 arranged res )ectivel above and below the axle 7, said shafts having reduced end portions or extensions 2] and 22? which take bearings in the disks or heads 9 as shown in Fig. (5; i'hrangcd on the reduced ends of these shafts and abuttingihe body portions thereof are removable flanges 23, each pair of flanges 23 and the body portions of the l I associate shafts 21 and 9.2 constituting a 23 on a reduced end portion of the shaft and suitably secured thereto. Each gear wheel 24 is provided with hubs or collar portions 2st and as shown 111 F 1g. 6 is arranged be tvveen the contiguous flange 23 and the adjacent face of one of the disks 9. It will .1 be further observed from Fig. 6 that the corresponding gears of the two spools are out of line or register with each other this arrangement being effected by turning the collar portions 2st of the corresponding gear wheels in opposite directions. The gear Wheels 241- are adapted to be driven by a pair i the construction of gear wheels 25, each gear wheel 25 be in mounted on a sleeve 26 which'is slidably supported on the shaft 7. The disks 9 are provided with hub portions 9 through which the sleeves 26 pass and slidably fit, beingsuch that each disk Qbears on the associate sleeve 26. Each gear wheel 25 is secured to the inn r reduced end portion 26 of the associate sleeve 26, this reduced portion between the gear 25 and the The left-hand sleeve 26 is formed with an elongated slot 27 and the right-hand sleeve 26 with a corresponding slot 28. A short pin29 fixed to "27and a longer the shaft 7 engages the slot screw pin 30 secured in the shaft 7 engages with the slot 28. The pin and slot connections between the shaft. 7 and the sleeves 26 compel said sleeves to participate in rotary movements communicated to said shaft while permitting endwise movement of. said sleeves relativel Y to said shaft. The two sleeves are held in fixed relationto each other lengthwise of the shaft are adapted to be moved along said yvith and from the spool gears by devices shaft simultaneously for the purpose of c011- necting and disconnectlng the driving gears fllVlilQll comprise a pair of bifurcated arms .31, each bifurcated. arm partially embracing one of the sleeves 26 and being arranged be tween a pair of spaced flanges 32 on said sleeve as shown in Figs. 3, 5 and 6. As will ing 10. The arms rearward and each '65 be clearly understood from Fig. 5 the flange portions .of the sleeves 26 extend outward and beyond the hub portions of the heads 9 and are arranged exteriorly of the stationary casing 10. It will also be seen that the bifurcated arms 31 are exterior of the cas- 31 extend horizontally tcrminates in a col ar portion 33 which engages with a slide rod providing clearance for 1 the teeth of the associate gear wheels 24.

til

34, being suitably secured thereto as by a pin 35. The slide rod extends through the casing 10 behind and parallel with the shaft 7 and hears near its ends in the disks or i heads 9. Said slide rod may be moved endwise by a finger piece 36 (Figs. 3 and 5), said finger piece having a collar portion 37 which surrounds and is suitably secured to the rod 34, the finger piece proper extend ing upward through a slot in the casing 10 and being operative from outside said casing. It will be understood that at one time the driving wheels 25 are maintained in mesh with the gears at the ends of the upper ribbon spool so that if the shaft or axle 7 were rotated its motion will be communicated to the upper ribbon spool to wind the ribbon 20 thereon and unwind it a. corresponding extent from the lower ribbon spool which is disconnected from the shaft.

the finger piece ribbon 20 is led from the under side of the hub of its lower spool upward and forward over the rounded lower edge of the platen l7, thence passing upward'over the front or printing face of said platen over the rounded upward edge thereof and. thence rearward and upward to the under side of the hub of the upper ribbon spool. The printing face of the platen 17 is concentric with the casing and is slightly within the curvature of the casing so that the printing portion of the ribbon 20 overlying said face will not project beyond the casing, the ribbon being thus well protected against accidental contact with the papcr or hands of the operator. Furthern'iore, as only a small portion of the length of the ribbon is exposed at one time opposite the slotuvay, the liability of the rear face of the work sheet to smut from contact with said ribon is minimized.

In order to indicate to the operator when the winding ribbon spool full and when the direction of ribbon feed should be reversedfll provide devices comprising a curved block 3 of wood which bears on the slide rod 34 and is provided near its ends with bearing plates 39 which partly embrace the rod 34 and are secured to the block 38 as by I ivets 0. The block 38 is adapted to swing freely on the rod 34 as a pivot and is normally 5 maintained by gravity in the position shown Further it will be apparent that if the slide From Fig. 1 it will be understood that the in Fig. 1. Endwise movement of the block 38 is limited by collars 41 fixed to the rod 34 as shown in Fig. 5. The construction and disposition of the block 38 is such that when the coils of ribbon '20 on the winding ribbon spool reach a predetermined diameter the ribbon will frictionally engage with the curved face of the block 38 and will turn said block on its pivot 34 in the direction of the arrow in Fig. 1.

Overlying the rear upper side of the easlng 10 as shown in Fig. 1 is a curved plate 42, said platebeing provided at its upper side with ears 43 which are curled around the rod 11 and serve to connect pivotally the plate 42 therewith. Angularly disposed portions 42 are bent inward from the lower edge of the plate 42 passing through slots 44 in the casing 10 and contacting with the block 38 above the pivot thereof. The construction is such that when the block 38 is swung on its ivot 34 as above described it will act to swing the plate 42 rearward and upward on its pivot 11 and will bring the lower edge portion of said plate into the path over which the work sheets are introduced into the machine, thus blocking the introduction of a new work sheet and notifying the operator that the ribbon 20 should be reversed. When this reversal has been accomplished by the actuation of the finger piece 36 the operator next presses the plate 42 back to normal position, causing the angular portions 42 to turn the block 38 back to normal position.

As clearly shown in Figs. 5 and (3, the peripheries of the disks 9 project outward beyond the ends of the fixed casing 10. The projecting portions of the disks provide bearings for movable tubular sections 4-5 and 46 which are in effect continuations of the fixed casing 10, being of the same diameter but which unlike the casing 10 are adapted to be rotated when the shaft or axle 7 is turned. The left-hand end portion of the deviceor rotary tube 45 bears on the periphery of a head 47, said head being provided with an inwardly extending hub 48 which is secured to the shaft 7 by a screw pin 49, said screw pin as shown in Fig. 6 connecting the rotary tube 4.5, the hub 48 and the shaft 7 so that they will all three turn together. The member col'nprising the head 47 and hub 48 may be of the construction found in the platen releasing mechanism of the Monarch typewriter and such as is disclosed in the pending application 'of Hubbard N. Josleyn, Serial No. 335.430,

filed Sept. 20th, 1906. Aline spacing ratchet wheel 50 bears on the outward projections 47 on said head 47 and is or may be normally connected with said head by releasable devices shown in. said Josleyn application. The righthand device 'or rotary tube 46 bears on the. projecting portion of the associate head 9 at its left-hand end, and at its right-hand end is supported on a head or end piece 50 which is secured by a set screw to the axle 7. The screw pin 30 secures the rotary tube'46 in fixed relationship with the shaft 7.

A hand operated'pawl mechanism (notshown) of an'ysuitable sort, and which may comprise a pawl 50 operated by a handle 50 as found in the Monarch machine, is adapted to cooperate with the ratchet wheel 50 to turn the same step-by-step, this stepby-step movement being communicated to the shaft 7 and the tubular end sections 45 and 46. A detent (not shown) engages with the teeth of the ratchet wheel 50 to maintain the connected parts in adjusted positions.

nism comprises sections 51 of a main feed roller, said roller sections being mounted on a shaft 52 (Fig. 1) and as appears from Fig. 4 being spaced apart at the rear of the casing and so as to engage. with the end devices 45 and 46. The shaft 52 is supported in arms 53 pivoted at to brackets 55 on the slide bar 5. Springs 56 press the feed roller constantly toward the tubes 45 and 46. Arms 57 pivoted at 58 in the brackets 55 carrya shaft 59 which supports the sections (30 of a secondary feed roller, said sections being spaced apart and caused by springs 61 to cooperate with the tubular devices 45 and 46. The feed roller sections project. through openings in a curved deflector or paper apron 62 of the usual character, said paper apron being normally pressed upward by springs 63 on the arms 57, said apron being hung on a rock shaft 64 pivoted on the platen frame. Arranged above the apron 62 is a paper table 65 of the usual style. The rock shaft 64 carries lugs 66 which are adapted to cooperate with pins 67 vto swing the arms downward, thus releasing the feed roller 51 and causing small rolls 68 on the extended lower ends of the arms 53 to engage with the arms 57 and effect the. release of the feed roller 60 and remove the pressureof the spring 63 to a large extent from the paper apron 62. The shaft 64 may be rocked for this purpose by devices of top plate 1.

fingers of the usual or suitable character may be mounted on the rod 11 near the ends thereof so that the pressure rolls 70 (Fig. 1) of said paper fingers may engagewith the tubular devices and .6, but not withithe cover plate 14.

The novel iibbon1necl1a.nism above described may be and preferably is employed in connection with the usual or suitableribbon feeding and controlling devices for the regular or main ribbon and which may be briefly described in connection of the drawings. A narrow ribbon 71 which may be termed the main ribbon and is the usual ribbon of the machine, is i111 pregnated with copying ink and is mounted on spools (not shown), one at each side of the machine above the top plate and forward of the platen. Midway between the spools the'ribbon T1 is threaded through a vibratory ribbon carrier or vibrator 72, which is vertically disposed and supported on an upright guide 73, said guide being secured by screws 7a to a depending'portion 75 of the The lower end of the ribbon carrier or vibrator 72 is bifurcated and carries a pin T6 which cooperates with the slotted forward end, of an operating lever 77 pivoted at 78 on a lug 79 depending from the top plate. The rear arm of the lever 77 is formed with a slot 80-which receives a pin 81 carried at the upper end of a link 82. Said link is adapted to be actuated from'the printing keys in a known manner and to be moved back and forth along the slot 80 to vary the throw of the ribbon 71. As is well known the printing portion of the ribbon 71, within the control of the vibratory ribbon carrier, is normally below the printing point but is vibrated up and down by the train of devices comprising the operating lever and actuating link during the operation of the printing keys. j

The printing instrumentalities are not shown but they are or may be ofthe usual character comprising type bars which are swung upward and rearward, causing the types to actagainst the front face of the platen 17 which is further adapted tobe moved between letters by the usual spring drum and escapement devices.

The work sheet or master sheet'shown in- E ig. 1 and designated by the numeral 83 is of a width snilicient to extend the full length of the stationary casing 10 and be vond the 5" i 'l i v be within the control of the g mechanism or devices com- 51, 0 and 2'0. In the which the present form of particularly do gned the itcd after the i and divided tor, Con- .Sirticies,

with Fig 1 to cover the printing point nae so-that the side margin of v operates. through the Weight, Rate, Freight, Advances,

Pre-Paid, etc. Prior to introducing the work sheet into the machine the feeding devices are released so that the work sheet may be passed around the casing and the first line that is to receive writing brought opposite the printing point without affecting any of the other parts. After the work sheet has been thus adjusted the lever or finger piece 69 is operated to restore the feed rollers 51 and to operative positiont It will probably not be necessary to release and restore the pressure rolls on introducing the sheet, but if found desirable this can be done byhand in the usual way. From Fig. 1 it will be apparent that the work sheet 83 passes upward over the printing point-and between the main ribbon 71 and the auxiliary ribbon 20 so that when the printing instrumentalities.are operated the front face of said work sheet will receive type impressions through the main ribbon 71 while the rear face of said work sheet will receive corresponding negative impressions from the supplementary ribbon 20. When the first line of'writing has been completed the usual line spacing-handle may be operated causing the pawl -(not shown) to act on the ratchet wheel 50, turning said ratchet wheel and also turning the rotary tubes 45 and 46. During paper feeding devices will cooperate with. said tubes toadvance. the worksheet through a line space distance. F urthermore, the turning of the ratchet wheel 56 shaft 7 to cause the driving gears 25 toturn in'the present in stance the upper jgear wheels 24, thereby giving a rotary movement to the upper rib b'on spools 21, 23 in the direction-Quit the arrow in Fig. 1, causing the supplementary ribbonQO to Wind on said spool and to unwind a corresponding 'amounhfror: lower spool. This movement of the supple mentary ribbon is suflicient to bring a fresh portion of the ribbon opposite the printing line. If from time to time pending thecompletion' of thework sheet or master sheet, it is necessary to remove the same from the machine and thereafter re-introduce said sheet, it should be done while the paper feeding devices are in released position in order not to feed the supplementary ribbon except through regularwunit distances of movement. When the mastersheet has been fully completed, it will contain two sets of impressions of the work, one set on the back of the master sheet and oneon the front of the master sheet, said impressions being in copying ink. master sheet middle of a dozen or fourteen sheets of tissue copie on the tissue sheets in the usual man ner. By this method I have found in prac- As has been described, the.

this turning the pile containing as many a and press tice that twelve or fourteen good typewritten press copies of the work may be obtained.

The supplementary ribbon spools herein shown have a ribbon capacity equivalent to about one hundred and thirty linear feet of half inch ribbon and in practice will, under.

ordinary conditions, outlast two of the usual half inch main ribbons.

In case it is necessary to make an erasure to correct an error or for other purposes, the master sheet must be removed from the machine and the imprints on both the front and back faces separately erased.

It will be noted that the side margins of the master sheet where they cooperate with the paper feeding devices are blank. These margins may be used for notes and one of them, usually the left-hand one, to cooperate with binding devices, said master sheets usually being filed away in binders for reference purposes.

It Wlll further be observedthat by my present invention I provide in combination with the platen, means for supporting aribbon as wide at least as the length of the printing line on the platen and means for feeding said ribbon transversely of the rinting line; that said last named means is automatically operative, being controlled by the means for line spacing the work sheet; that means are provided for reversing the direction of the longitudinal feed of the ribbon; that associated with said reversing means are means for automatically indicating when a predetermined point in the feed of the ribbon hasbeen reached; that this indicating means comprises a vis ual signal which is operated by a member, in the present case 38, which member is adapted to be turned by gravity and also by the coils of ribbon; that when turned by the ribbon coils, said member moves said visual signal into indicating position; that the ribbon carrying means are arranged at opposite sides of the platen and extend substantially the full length thereof; that said ribbon carrying means comprise in the present instance a pair of spools provided with detachable flanges; that one of the spools in the prese t instance is arranged above the platen and the other. below the platen, the platen being that of a front-strike machine; that the ribbon carrying means or spools are movable bodily with the platen so that the bodily relationship between the platen and the spools is unvarying although the spools may turn on their axes for feeding the ribbon; that the line spacing means are operative independently of the platen and comprise a ratchet wheel and a shaft; that the ribbon feeding mechanism is connected with said shaft and through it with said ratchet wheel, said ribbon feeding mechanisnadncluding gears on said shaft and gears on said ribbon spools; that the shaft and the ratchet wheel are separate from the platen and independent thereof, so that the ribbon may be fed across the face ofthe platen transversely of the printing line while the platen is stationary; that the ribbon above referred to, which is in the present instance a supplementary ribbon, constantly covers the printing point on the platen; that asso ciated with the supplen'lentary ribbon is asecond ribbon or what may be termed a main ribbon which is provided with vibrating devices for moving it up and down to cover the printing point; that the vibrat ing devices operate independently of the platen as well as of the line spacing devices and also of the ribbon feeding mechanism of the supplementary ribbon; that the line feeding devices advance the work sheet between the main and supplementary ribbon so that said work sheet may receive simultaneous impressions on its front and back from the two ribbons; that a hollow casing is provided combined with means for feeding an ink ribbon within said casing: and
