A THU w. smrrn, F NEW YO K, 1:. Y., AssIenOR 'ro REMINGTON TYPEWRITER column, or ILION, NEW YORK, A CORPORATION OF NEW YORK.
a To all whom it may concern Be it known that I, ARTHUR W. SMITH, a citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Typewriting-Machines, of which the following is a specification.
The main object of my present invention is to provide new and improved paper con trolling devices for type-writingmachines, said devices being especially adapted for use with a plurality of work sheets which are required from time totime to be relatively adjusted in respect to each other. a
To the above and Other ends which will hereinafter appear, my invention consists in the features of construction, combinationsof devices and arrangements of parts to be hereinafter described and particularly pointed out in the'claims. i
Incarrying out my invention in the resent instance I apply to the platen of: a emington typewriting. machine, to which the preferred form, of my invention is shown in the drawings as adapted, two sets or pairs of paper fingers or: guiding devices, each pair extending upward at the front or deliveryside of the platen and transverselyof the paper deflector which extends along the platen below the printing line. The pairs of arranged lengthwise of the platenbelowthe printing line and supported at its ends on the platen frame partiof the carriage. The

sheets of different widths, and properly to.
feed or advance the work sheets after such relative adjustment, certain of the work sheets being removed and replaced from time to time by other sheets.
My invention will be described in detail in connection with the accompanying drawin s wherein p igure 1 is a fragmentary front elevation of the platen carriage and upperpart of a Remington typewriting machine showing" my invention applied thereto.
Figs. 2, 3 and 4 are transverse sectional views taken respectively on planes indicated by the dotted lines m, y g and a a in Fig. 1, and showing different stages of adjustment of the work sheets. a
Fig. 5 is a fragmentary perspective view illustrating the mounting of the paper fingers and devices for releasing the same.
Referring to the drawings, the platen of the Remington machine, which platen is designated as 1, is supported on a carriage which comprises a platen frame proper and a truck, said frame includingend bars or plates 2 and a connecting cross bar 3 which extends under the platen and lengthwise thereof. The platen frame is supported on a truck which comprises end bars 4: and connecting front and rear bars, of which only the rear bar is shown. The front and rear bars are grooved to cooperate with roller bearings 6 which connect the carriage with groovedguide rails at the front and rear of the machine, the rear guide rail 7 being illustrated, said guide rail being fixedly supported on a topplate 8 which is comprised in the main frame of the machine. The rotary platen 1 is provided with line spacingpdevices including a. ratchet wheel 9 connected to the right-hand end of said platen. 1 Letter feedingdevices and key actuated type bars of the usual construction are also provided although they are not illustrated in the drawings. ,Associated with the platen are paper feeding and controlling devices of regular construction comprising a main feed roller and a secondary teed roller. The main feed roller is composed of sections 10 supported on a rod 11; while the secondary feed roller is composed of'sections 12 mounted on a rod 13. The main feed roller cooperates with the platen at itsrear or introductory side, while the secondary teed roller cooperates with the lower front side, of the platen. The main and secondary "feed rollers are mounted o na frame coin n'isingtransverse bars 14 which provide supports for the rods 11 and 13. The bars 14 arepivotally connected at 15 with three-armed levers 16 'iulcrumed on rods 1-7, the upward extensions of said levers being adapted for cotiperation with releasin'g devices or'fingers 18 on a rock shaft 19 mounted on the carriage and provided at its left-hand end with a releasing arm or lever 20' having a horizontal'leftward offset 21 and terminating in an upstanding finger piece-or release key 22. When said release key is pushed rearward'from the Fig. 2 po- Sltl'On tothedotted line position of Fig. 3, it operates to rock the'shatt 19, causing the fingers 18 to actuate the three-armed levers 16 a-nd move thev 1113111 and secondary feed v rollers to the released or dotted line position illustrated in Fig. 2; Such movement is in opposition to the springs 23 which will act to restore the feed. rollers when the key 22 is released. The feed rollers may be locked in released position by devices comprising a springpressed latch or lever 24 pivoted on a rod 25- on the rearwardly extending part of the-leftharid end plate 2. The rear arm. of i the latch 24 terminates in a key or finger piece 26 and its forward end is curved npward to provide an engaging portion 27. \Vhen the release key 22 is pushed'hack to the dotted line position, the finger piece 26 may be depressed to swing the latch 24 on its pivot from the full line to the dotted line position of Fig. 3, this movement causing theengaging portion 27 to engage with the offset 21 to retain the release key and the main and secondary feed rollers in inopera-. tive or released position. The friction between the offset 21 and the contact edge of the part 27 due to the springs 23 is sufiicient toi'naintain the partsin locking engagement, but it is only necessary to press the release key 22 slightly toward the rear to releasethe latch'and permit the parts to rc- 1 turn to normal position when the key 22 is freed. Pivotal movements of the latch 24 are limited by a headed screw pin 23 threaded into the inner face of the end plate 2, the shank of said pin cooperating with a slot24 -tornied in the latch 24. When the i Y latch is not in use the upper end of the slot 24 engages Wi hthe screw pin 28 to maintain the latch in the position illustrated in F A restoring spring 24" is provided for the latch. said spring being coiled around the rod 25 and so connected to the latch as to maintain it normally in the Fig. 2 position. The feed rollers cooperate with the platen through openin s in a paper dc doctor or guiding device 29 made ot sheet metal and curved around the rear and under sides of the platen, the forward edge of said guiding device terminating at the front face of the platen below the printing line. The deflector drops away from the platen when the feed rollers are released. Mounted on the carriage above the rear end portion oi the deflector is a rearwardly inclined paper table 30 novided at its left-hand side with an adjustable side guide or gage 31.
The mechanism as thus far described is not new and is common to some styles of llcmington typewriting machines.
As herein exemplified. my invention comprises two' sets or pairs of paper fingers which are mounted on a support or bar designated as a whole by the numeral 32 said bar extending lengthwise of the p aten at the front side thereof and below the printing line. The bar or rod is generally square in cross section but its ends are reduced to provide cylindrical portions 33. the outer extremities of which bear in the end plates 2. Also near its middle the paper finger bar 32 is provided with reduced cylindrical hearing portions 34 which cooperate with bearings 35 formed at the upper ends of: two parallel arms 36-comprised in a U-shaped bearing member 37 that is secured to the front face of the cross bar 3 by screws 33. The tern'iinal paper fingers 39 are mounted. one on each of the cylindrical end portions of the paper finger rod. These terminal paper fingers are made of sheet metal and have their lower ends bent around. as indicated at 40. to bear loosely on the cylindrical parts i3. Thence the paper fingers extend upward transversely of the guiding device or deflector 29 and of the platen and at their upper ends are provided with pressure rolls 41 which are adapted to cooperate with the trout upper side of the platcn above the printing line. The lower or hearing portions ot the terminal paper finders are extended outward and terminate in forwardly bent lips or finger pieces 42. Also there is fixed to the outer end of the hearing portion an upwardly extending arm or finger piece 43 by which the paper fingers may be turned on. and relatively to the supporting rod. The finger piece 43 is perforated to afford a passage for the supporting rod and has connected to ita restoring spring 44 which extends rearward and is anchored to a pin 45 that projects lat rally fromrthe inner face of the associate end plate 2. Each paper finger 39, as will be understood, is provided with one of these restorlng sprlngs l4: whlch normally maintains it in cooperative engagement with the platen.
or with the paper thereon. It will be understood that the terminal paper finger 39 may be swung forward away from the platen independently of and without disturbing either its companion terminal paperfinger or the supporting rod 32. a
The other set or pair of paper fingers, each of which is designated as a whole by the reference numeral 46, are arranged between or intermediate of the terminal paper fin gels and bear on the squared portions of the supportingbar or rod 32 along which said paper fingers are slidably adjustable. Each intermediate paper finger 46 is preferably of sheet metal and has its lower end formed or bent, as indicatedatd? .to providea rectangular bearing opening which slidably engages the squared portion of the supporting bar 32, the construction being such that the paper fingers &6 are slidably supported on the bar but a turning movement communicated to the bar will turn also the paper fingers 46; and, conversely, if'the pape fingers 46 are pulled, away from the platen'the bar 32 will be given a rotary movement andthe associate paper fingereG will also be swung away or released. From the supporting bar the paper fingers 46 ex tend upward transversely of theplaten and of the guiding device 29 andtheir upper end portions are ofiset'or inclined inward indicated at 48, and support at their upper endspressure rolls 49 which cooper ate with the upper front sideof the platen above the printing line and slightly above the pressure rolls ll. It will be understood that a rotary forward movement communi cated to the paper finger bar 32 will be effective to swing both of the paper fingers t6 forward away from the platen and that such movement will not afiectthe terminal paper fingers 39. In order conveniently to turn the bar devices are provided comprising an arm 50 which is suitably secured to the end portion of the bar 32which projects through and slightly beyondthe lefthaud end plate 2. The arm 50 is arranged outside said end plate and extends vertically upward, itsupper portion 50 being bent or twisted so that it in a plane parallel with the platen axis. To the lower part of the portion 50 is pivoted at 51 a finger piece or key 52 which is arranged behind and in contar-t with the rear face of theportion 50 and is adapted for swinging or pivotal movement across said face about the 1pivot51, such movement being limited by a pin 53 whichprojects rearward from; the upper end of the portion 50 into a slot 54 in the finger piece'52. This finger piece serves both as a hey by which the paperfingers46 may he released and also as a latch. to hold the paper fingers in released position, said finger piece being adapted for cooperation with a plate or abutment thatis secured by a screw 56110 the top of the left-hand end bar 4: and has its inner edge projecting beyond the inner face of the end bar. so located that when the arm-50 has been swung forward by .pulling'on the key 52 the latter may be swung pivotally leftward. about the pivot 51 until it has been moved into the plane of the plate 55, so that if said key 52 be now released it will contact with the front edge of said plate, the latter serving as a stop to maintain the intermediate paper fingers released. The locked off position of the key 52 is as illustrated by dotted lines in Fig. 3. To restore the intermediate paper fingers and to maintain them in cooperation with theplaten a coiled spring 57 is provided, the forward end of said spring being hooked into a hole in the arm 50, the rear end being anchored to a. pin 58 project ing laterally outward from the end plate 2. It will be understood that to restore the parts when the intermediate paper fingers are locked ofi, itis only necessary to swing the key 52 rightward to clear the plate or stop 55 and permit the spring 57 to become efiective to swing the arm 50 rearward and through it to turn the bar 32 and restore the paper fingers 46. During the releasing and restoring operations the reduced end 1301:". tions '33 of the bar 32 will turn freely in the bearing portions of the terminal paper fingers. As illustrated in Fig. 1, the usual line gage member 59 is preferably employed with the present construction.
lVhile. my present invention is adapted "for use with many different styles of work sheets and systems of billing. it wasespa cially designed and is particularly suitable for employment with three work sheets of. difi'er'ent widths such as are illustrated in the drawing and indicated by the letters a, 7) and. (3. Accordingly, the operation of the invention will be explained in detailin connectionwith said work sheets, although of course it is to "be understood that the use of themvention 1s not restricted to the specific character oi work sheets shown nor to such manipulations as are hereinafter detailed.
The widest sheet (t. sometimes called an auditors proof sheet. adapted to re-l ceive du 'ilications oi. all matteravrittcu on the machine and, beingithcinnermost sheet The plate 55 is customer.
ten ,or filled.
throughout the working length of the platen transactions of a considerable number of customers,which transaetions take place in the course of the day. This proof sheet remains in the machine until it is fully writ- It extends substantially and its side margins are controlled by the terminal or duplicate paper fingers 39. The audltors proof sheet a is introduced into the machine in the usual way over the table 30 r with itsleft-hand edge in contact with the margin gage 31, and, ordinarily together with its carbon sheet a, is passed around the platen between it and the paper deflector and up at the front of the machine under the ,paper fingers and between thepressure rolls and the platen. Thereafter it is intended that the proof'sheet shall remain under control of the paper fingers 39 and their pressure "rolls until it hasbeen completely filled in. The condition of the'machine after the sheet a has been introduced is illustrated in Fi 2'. The ledger sheet Z), usually with its car on b, is next introduced into the machine behind thesheet a and its carbon.
Sometimes the carbon sheet for the sheet .5 is introduced with the statement but that is a matter of preference. The sheet 6, it will be understood, may, and ordinarily will, contain a number of entries from prior transactions so that it; is necessary to adjust it variably at different times in order to bring the first blank line on it opposite the printing line. To facilitate the adjustment of the sheet a, the main and secondary feed rollers are released and locked off and the intermediate paper fingers 46 are also released and locked off, all as illustrated by dotted lines in Fig. 8. The sheet Z) is narrow enough to pass freely between the terminal or duplicate paper fingers 39, and I consequently with the feed rollers and intermediate paper "fingers locked off. a free passageway is afforded for the sheet I) which may readily be passed around the platen and advanced to the proper position for receiving the first line of writing The sheet 5 is preferably adjusted against the inner edge of the left-hand paper finger 89, which thus serves as'a margin or side gage or guide for said sheet 6. It has been found in practice that the paper finger in itself provides an adequate side gage but if preferred of course a separate gage that may be connected with the paper finger or a special guide part made integral with the paper finger may be employed. After the ledger sheet 7) has been thus adjusted the intermediate paper fingers are released to engage with the sheet I) and hold it in place or adjusted position while the sheet 0 is introduced and adjusted. The sheet 0, or statement sheet, is less in width than the distance between the inner edges of the two paper fingers 46 so that these paper fingers do not interfere with the introduction of the statement sheet. A clear and unobstructed passageway is thus afiorded for the statement when. as has been assumed, the feed rollers are locked in released position. Accordingly the sheet 0 may be passed freely around the platen, being introduced beneath the other two sheets over the paper table and so that when it is brought to the front side of the platen it will be on the outside of the other sheets. In adjusting the statement sheet 0 the inner edge of the left-- hand paper finger 4G is preferably employed as a side or margin guide or gage, although as has been stated in connection with the terminal paper fingers, a gage separate from the paper finger 4G or a special guide part on or part of said paper linger 46 may be employed if preferred. The sheets having all been adjusted as described, the feed rollers are restored to engagement with the platen (Fig. 4), said feed rollers assisting primarily to retain the statement sheet in proper position although of course they cooperate with the other shcets as well. The line gage 59 is also of assistance in retaining the statement 0 in proper relationship with the printing line, as well of course fa cilitating the adjustment in respect thereto of all of the sheets as they are introduced. With the sheets thus adjusted and the various paper controlling and feeding devices related as last described, the necessary entries may be made on the statement sheet and duplicated through the interposed transfer sheets or carbons on sheets 7) and a, it being understood that when the platen is advanced for line spacing during the course of the writing, all of the sheets will be simultaneously moved upward a line space distance, with the result that their original relationship is maintained until the entry has been completed. Thereafter the sheets 0 and b are withdrawn from the machine the platen is line spaced to advance the auditors proof sheet (t to the next writing line, and other ledger and statement sheets are introduced and adjusted in the manner hcreinbefore set forth.
The paper fingers afford the best means that have been dex ised for carrying out the purposes of my present invention, but it is apparent that for some purposes the pressure rolls such as 41 and 49 may be otherwise mounted than on what may strictly be termed paper fingers, it being necessary only to insure that said pressure rolls are capable oft control and: adjustment in the man ner hereinbefore described and ,explaii'ied.
Various changes may be made without departing from my invention, 7
