PAPER-ROLL SUPPORT FOR TYPE-WRITING MACHINES.

Specification of Letters Patent.

Patented Dec. 8, 191:1,

Application filed August 27, 1909. Serial no. 514,875.

To all whom it may concern Be it known that I, SAMUEL R. SHoUr, a citizen of the United States, and a resident of Hoboken, in the county of Hudson and S State of New Jersey, have invented certain new and useful Improvements in Paper- Roll Supports for Type-\Vriting Machines,

of which the followingis a specification.

This invention relates to paper-feeding l attachments for typewriting machines. 7

As is well known, there are certain classes of work which are facilitated by feeding one or more long strips of paper intothe typewriting machine, the. end portion or portions thereof usually being detached after each individual piece of work has'been completed, and the newly-made ends of the strips being left in the machine for a repetition of the typewriting operations, thus doing away with the necessity for repeatedly. adjusting separate sheets in the ma- .chine. \Vhen a large number of similar forms are to be filled in, and when, as usual, rapid operation is desirable, it has been the practice to provide a series of these forms printed on long strips which are wound 'upon spools or otherwise suitably rolled, and to so mount the spools or rolls in connection with the carriage of the typewrit- 39 ing machine that said strips may be fed through the machine in the usual manner. If two or more copies of the typewritten matter are desired, the requisite number of strips are superposed and suitable manifolding material interposeditherebetween, in the same manner as is customary when individual sheets of paper are employed.

In feeding strips of paper from spools or rolls to the platen of a typewriting marolls to be either mounted upon or moved by the typewriter carriage, in order that the former may move in substantial uniformity with the latter to preserve suitable alinement of the written work and to insure proper direction of movement of the strips as they are fcd through the machine. \Vhere a large number of these rolls are employed, it will be apparent that, if they are 00 mounted upon the carriage, the latter will be subjected to unusual and excessive weight. with a corresponding increase in the inertia to be overcome in advancing the carriage and in the momentum to be checked repeatedly during its advancement. while,

chine, it is customary for said spools or if the rolls are so mountedthat their weight is not borne by the carriage but they are advanced and stopped either directly or indirectly thereby, there will still remain the 0b]ections connected with theimposition of additional inertia andmomentum upon the carriage. Manifestly, therefore, in either case, and irrespective of the number of paper rolls that may be employed, the typewriter mechanism is subjected to'strains and jars whichit is very desirable to obviate, in,

the interests of durability, ease, uniformity and rapidity of operation and general efliciency.

The principal object of the present invention is the provision of means. other than the carriage for supporting the weight of the paper rolls, and means apart from any portion'of the typewriting machine for receiving the strains due to the step-bystep movement of the paper-roll support, together with means for insuring substantially identical movements ofthe typewriter carriage and the papenroll support.

My invention will be more readily understood by reference to the accompanying drawmgs, forming apart of this specification, in which, r

Figure 1 is a. top plan view of a common form of typewriter carriage, with a device embodying my invention applied thereto; Fig. 2 is an elevation of the paperr0ll support, with the actuating bar therefor shown in section; Fig. 3 isan enlarged end elevation of another form of removable paperroll support embodying my invention; Fig. 4 is asectional detail view ofv one of the winding rolls and its connections, hereinafter described, and Fig. 5 is a detail view. in sideelevation, of the pawi and cooperating parts shown in Fig. 2.

Referring now to the drawings in detail. numeralll refers to the supporting frame for the platen 1'2 of an ordinary form of typewriting machine. said frame having the usual vertical pivotal movement in conned. tion with the bar 13 of the carriage. which is pro ided with rollers 14 adapted to travel upon a suitable track or rail 15. the front of said frame 11 being similarly supported upon a forward track rail (not shown). and the platen 12 has the usual longitudinal movement imparted thereto by a cord or tape (:1 which leads from thespring-actuated drupn 6O andissecured to the carri w The platen shifting and line-spacing mechanisms are not shown in the drawings, inasmuch as they are of common and wellknown construction and form no part of this invention." I

Mounted upon the table, desk or other support 16 for the typewriter, and located at the rear of the latter, is a frame 17, the four lower legs 18 of which are provided with rollers 19, which are preferably grooved, and which travel upon track rails 20 carried by a supporting plate 21 secured to the desk or table 16. Suitably journaled in the bushings 22"v inthis frame 17 is the axle 22 of a spool-23, upon which is wound the roll 24-of paper to be'fed through the type- ,writing machine. These bushings 22 are adjustably mounted in the upper ends of the upwardly-projecting arms of the frame 17, where I have shown thumb-screws 26 for the purpose of fining said bushings in any desired positions of lateral adjustment. I prefer that a spring shall be interposed between the endof spool 23 and the adjacent of said bushings, in order to provide a re against too rapid unwinding of the 3 from roll 24. he frame 17 includes a laterally-projectarm- 27, to the end of which is secured s end of a wire or tape 28 wound upon a spring-actuated drum 29, so that there is a constant pull upon the entire frame 17, tending to move the same'in the direction of the'drum 29, which direction is the same as that in which advancement of the typewriter carriage takes place duringthe writ-.

ing operation. Pivoted to this arm 27 is the lever 30, to the lower end of which is adjustably pivoted the vertical arm 31 of a 4 J. hell-crank lever fulcrumed at 31 to the end of the arm 32 on the frame '17. To the end of the horizontal arm 31 of said bellcrank .iever-is. pivoted the pawl 33, in position to cooperate with rack 34 carried by base-plate A spring 35, in tension between the end of arm 27 and the rearwardly-pro]ectlng arm 48 of the pawl 33, tends to yieldingly retain said arm 48 in an elevated position, and-thus said pawl in a depressed position, relative toarm 31 of the bell-crank lever, and to retain said arm 31, and thus said pawl, in an elevated position relative to rack 34, the pawl 33 being free from cooperation with rack 34 when sa d arm 1s in'its raised position. To facilitate lifting pawl 33 out of engagement with the teeth of rack 34, the parts are so shaped and d1- mensioned that, when pawl 33 IS in engagement with one of said teeth, the pivot 31 of the bell-crank lever is somewhat below a line-normal to the contact face of sa d tooth at the point of engagement of said pawl therewith, and thus movement of the vertical arm 31 of the hell-crank lever to the right the a: segment movement ofarm 31 of said lever upward, has the effect of moving pawl 33 away from said contact face of said tooth. A stop 19 limits upward movement of pawl arm 48, and consequently downward movement of the pawl 33 relative to horizontal arm 31 of the bell-crank lever, the opening -19 in arm 48, which embraces stop 49, being sufliciently larger than said stop to permit pivotal movement of pawl33, as and for the purposes described hereinbefore. Also, a stop 30, on frame 17, limits movement of the upper end of lever 30 to the right, and con-' sequently downward movement of said lever arm 31.

Suitably mounted on some portion of the typewriter carriage, and preferably on the rear supporting bar 13 thereof, is a rearwardly-projecting rod or bar 36, the free end of which extends to a position immediately in advance of the upper end of lever 30.

It will now be apparent that, when the typewriter carriage is advanced, the spring drum 29 will operate through the wire or tape 28 to advance the frame '17 until, advancement of said carriage having been checked in the usual manner, the upper end of lever 30 impinges against the end of the rod or bar 36. The effect of engagement between the end of said lever 30 and said bar will be to operate said lever to depress the end of the horizontal. arm 31 of the bellcrank lever, against the action of the spring 35, and thus to cause the pawl 33 to engage 100 a tooth in rack 34, thereby arresting movement of the frame 17. Thus, in stopping the heavily-loaded frame 17, no greater strain is imposed upon the bar 36, and therefore upon any portion of the typewriter frame and mechanism, than is required to actuate the lever 30 and depress pawl 33. hen the typewriter carriage is moved to the right (Fig. 1)'in the ordinary line-spacing opera tion, carrying therewith the bar 36, said bar 113 will act against the paper-roll support to move the latter with said carriage t0 the right, thus automatically returning said support to what may be termed its initial position, and preserving at all times the 115 necessary alinement between the-paper roll 24 and the platen 12 of the typewriting machine. During such movement of bar 36 to the right, said bar will be in engagement with the upper end'of lever 30, thereby tend- 129 ing to force pawl 33 into engagement with rack 34, but since said pawl is pivoted to arm 31 of the bell-crank lever,'and is held yieldingly in its depressed position relative to said arm by spring 35, it is manifest that 125 said pawl will yield pivotally upward to permit movement thereof to the right over rack 34. When a letter key or the spacing key is struck in operating the typewriting machine, the carriage automatically re leased for movement Y forward one step, under action of the usual actuating spring,

in a common and well-known manner.

will be apparent that the bar 36, rigidly secured to said carriage, will advance therewith, while movement in this direction of said bar 36 will release the frame 17 for movement under tension of the wire or tape 28. Before the inertiaof said frame-can be overcome, the lever is released to 'permitaction of spring to withdraw the pawl 33 from engagement .with a tooth in the rack 34, thus freeing the frame 17 for movement under action of the tension wire or tape 28, 16 such' movement continuing until the lever 30', '-impinges against the bar 36, overcoming the'igpower of the spring 35 and again forcthe pawl 33 into engagement with a tooth of the rack 3;, thus bringing the frame 17 to astop. Hence, frame 17 is not propelled by the typewriter carriage,.being sub- ]ect to its own independent propelling force, and movement of the frame 17 .is not checked by the typewriter carriage, but independently through reengagement at the proper point between pawl 33 and a tooth in the rack 34. It will therefore be seen, first, that the frame 17 is advanced by forces generated entirely independent of the 30 forces for automatically moving the typewriter carriage, I whereby no additional strains are put upon the spring employed for ordinary movement of sai carriage; second, thatabsolutely no port on of the 85 weight of the frame 17 and the paper roll or rolls carried thereby is borne by the typewriter carriage or any other part of the typewriter frame or mechanism; third, that,

while the typewritercarriage and the paper- 40 roll support have substantially identical movements, thus continuously retaining the paper roll or rolls in suitable position to properly direct the paper strips to the platen of the machine, movement of the said paperroll support is stopped and the momentum thereof overcome by means which form no part of and have no connection with the frame or mechanism of the typewriting machine, which thereby remains entirely free of unusual strains or strains not contem plated in the construction of the machine. In other words, all of the typewriter mechaisms perform their usual functions and nothing more, although they control the movements of the heavy traveling paperroll support.

In Fig. 3 I have illustrated the manner of mounting a plurality of paper rolls upon the traveling support. which in turn is mounted upon the desk or table that suport-s the typewriting,machine. In this I have shown two paper rolls 31 and 38, fies- ens 39 and 40 of the spools upon which aaiditiigolls are mounted; being suitably 1011!- hilleifinjlie 17'. Where two or more It i paper strips are employed, it is obvious that suitable manifolding material isintended to be interposed therebetween, and for this purpose I provide said frame with arms 41 m the ends of which is journaled the axle 42 of a spool upon which is wound a long strip of carbon or other duplicating paper to form the roll 3. The strips from therolls 37 and 38, material from the roll 43 therebetween, are passed over the idler roller -H, suitably j ournaled in said frame, and thence around the platen 12 of the typewriting machine, where the outermost strip is subjected to the action of the typeibars in the usual'man- In view of the fact that carbon or bther manifolding paper is relatively expensive, particularly when provided in the form of long strips, it is manifestly undesirable to detach the written-upon end portions of the paper strips in any manner which will necessitate the detaching of the end portion of, the carbon strip. I therefore prefer to provide, suitably journaled in the upper portion of the frame N, a roller 45 to which the end of the carbon strip is directed and upon which it .is re-woundto form the roll 16. The end portion of the strip from the roll 38 will projectfrom the platen of the typewriting machine in the usual manner, and after having been written upon may be detached for use- The strip from the roll 37 may be directed .toward the rear of the typewriter and there detached, or, preferably, as shown in Fig. 3, a roller -17 may be provided, suitably journaled in the frame 17, and said strip directed thereto and re-wound thereupon to form the roll 50, which may be retained for purposes of record. lVhen either or both of the rollers 45 and 47 are employed, I prefer to provide the axles thereof and the axle of the platen 12 with suitably-constructed sprocket wheels around which the sprocket chain 49iis passed, so that, as said platen is rotated during the line-spacing operations. said rollers 45 and 47 will be positively rotated through a corresponding arc to re-wind the carbon strip and the strip from roll 37, respectively. Ma-nifestly, re-winding said strips u on the spools or rollers 45 and with the strip of manifol'ding 47 will result in gradually increasing'.

the diameters of the rolls on said spools, thereby gradually increasing the peripheral velocities thereof, and, consequently, the velocities at which the strips will tend to be drawn to said spools. Inasmuch as the axles of said spools are rotated at constant velocities, it is necessary that means he provided for retarding the velocities of said spools as the rolls thereon increase in diameter. In Fig. 4' I have shown a preferred method of aooomplis'bingthis result, the spool 45 being loosely the M752 er" being of paper 0 rotative forcesfimparted thereto from the provided with an end-plate 53 which preances 54 to correspondinglyarranged depres 911$ 55 in a relatively similar plate 56 secured to the'axle 57 of the sprocket wheel 58., In the other end of noller 45 is arranged a spring 59, which tends to force said roller and the plate 54 thereon yieldingly toward the plate 56, whereby said plates 54 and 56 will be held in yielding frictional engagement." Thelefore, as the diameter of the roll said spool 45vis increased, the

spr cket wheel 58 will be overcome when nee ssary, tomake the speed of the re-winding operation conform at all times to the velocity of the moving strip as it leaves the To accomplish milar results,

analogous construction. v p Many modifications of minor details of ,my improvedpaper-roll support for typewriting machines will'doubtless readily suggest themselves tothose skilled in theart to which it appertains, and I therefore do not desire to limit'my invention to the specific constructionherein shown and described.
