Specification of To all whom it may concern:
Be it known that I, NELZI E FRANQIS Pn'ri'r, a citizen of the United, States, anda resident of Charleston, in the county of Charleston and State of South, Carolina, have invented a new and Improved Type- Vriting Machinaof which the following is a full, clear,zandexact description.- .1 j
Amohg the principal objects which the present invention has in view are: to provide a construction .to occupy a minimumof space; to provide an arrangement of type wherein a numberof characters may be arranged-to be employed and to provide a portable typewriting machine which is simeconomical and dura-ble in construction. One embodimentof the present invention is disclosed in the structure illustrated'in the accompanying drawings, in which like characters' of reference denote corresponding parts in all the viewsyand in which Figure 1. is av plan view of 'a typewrit-ing machine constructed in accordance with this invention; 2-is a front elevation of the same; Fig.3 is a side elevation of the same; Fig. dis a vertical cross section taken on the line l -45in Fig. 1; Fig. 5 is a detail view in side elevation,of the carriage mount-- ing and shifting vmechanism connected thereto; Fig. 6 is a detailview in vertical section taken on the line -66 in Fig. 2, showing the spacing vhcel of the carriage; Fig. 7 is a plan view of the type carriage .as seen from beneath, the rack bar, propelling wheel, guide bar and spacing bar being shown inconjunction therewith, said bars being illustrated in a fragmentary manneryFig. 8 is a top view ofthe inking pads; Fig. 9 is a face i 10 is a top View of the type pressure plates and printing frame, the selecting disk having been removed; Fig.11 is aview of the underside of the type carriage, the same being raised from printing position and the inking pads being thrown back away from the type and in position to be inked; Fig. 12 is a view of the frame forthe :type disks. the said disks. being removed therefrom; and Fig.1 18 .is view of the under .sideof the carriage and the type pressure plates, the type disks -having been removed and showing the reverse side of the construction illustrated inFig. 10.
The particular class of writing machines to which the present invention most. clearly belongs is that whereinthe individual type. are east or formed upon an integral or Letters 1?atent. Mai. 29, 1910;

The two pads 28, 2.8 are segmental in shape and. are faced with any suitable absonpti-ve' material, such as felt. The table formed individual type pads,
held within .a suitable or more series of characters disposed sub-l characters on the type disk 11. Tothe post arm 18 is rotated about the pivot 14 to 10- that the forward end, forms a finder 22, which drops into, or is depressed into, sawtoothed spaces 23-, 23 of the flange '20. Piv-I' otally attached to the arm 18 is a handle 24,
arm 18 is moved about theeircle It will be understoodthat beraised on a pivot 25in In the present construction post 14,-which I is extended upward through a' selecting positions of 4 the character on the 1 the arm 18 is arrested,
the circle ofcharacterson other. Tlie first mention-ed der of the pad 28 prevents the impingement of any other of the type upon the paper adjacent to the opening 3-1. The pads 28, 28 are raised to contact with the type pads 12, 12 by springs 35, 35.
Interposed between the plate 15 and the type pads 12 are pressure plates 36 and 37, the latter of which is grooved at 38 to pass the pressurefoot'formed in the carriage 19. The carriage 19 is provided with a circular opening 40 to house the type pads 12, 12
and pressure plates 36 and 37. Across the opening 40 is extended a bridge 41. To the upper surface of the bridge 11 are hingedly mounted the plates 36 and nections being formed at tively. The plate 36 is provided with an elongated slot-4st, through which is upwardly passed the pivot post 1%. The plates 36 and 37 are depressed against the upper side of the type pads 12, 12 by means of springs 15, 45, which are anchored to the bridge 41, the free endsresting loosely over the upper side of the plates 36 and 37. The plates 36 and 37 are so formed and disposed as to coincide and cooperate with the inking pads 28, 28. They serve the purpose of forcing the type, by a gentle pressure, against the inking pads withoutbinding the same, the springs 45, 45 being always in condition to yield to any binding pressure of the type upon the pad due to accidental irregularity of the pads.

The carriagel9 is mounted upon a base 47 of the machine by means of Standards 11.8, 48, in the upper ends whereof are provided bearings for a pivot rod 49. having formed thereon a rack bar 50. The carriage 19 is maintained in alinement by means of a guide rod 51, upon which it is slidably mounted by means of depended brackets 52. 52. The guide rod 51 is held in alinemcnt with the rod 49 by linkarms The carriage 19 is pivotally mounted by means of bearings 54: upon the said rod 49. By means of this construction and arrangement the carriage 19, may .be raised upward and away from the paper upon which the printing is being impressed, holding in mutual relation therods :19 and 51 and in guided relation the said rods to the carriage itself.

the wheel 55 that the said spring is wound to its highest tension by shifting the car- .riage 19 to the leftof the machine, or the inner margin line of to be performed. The wheel 55, in being thus carried to the left, is rotated so that the 57 is brought to its full tension and therein operates to rotate the wheel 55 to force the carriage in the opposite direction, or toward the right hand side of the machine. In this action it is retarded by the spacing mechanism.
The spacing mechanism consists in a spacing bar 58. having in the top thereof r'atc-het teeth 59. the spacing of which is spacing of In other words, the distance from the face'of one of the teeth 59to the adjacent tooth 59 is equal o the space required for the printing of each of the letters. The bar 58 is stationarily held in brackets 60, 60 mounted at each side of the base 47. To engage the teeth 59 there is provided a yielding toothed arm 61 and a fixed toothed arin 62. The yielding toothed arm 61 is pivoted at :63, and is provided with a stop post 64. The stop post 61 regulates the advanced position of the yielding arm 61 to which it is moved by a leaf spring 65. The leaf spring 65 is anchored on the bottom of the table 27, as is also the pivot 63, post 64 and arm 62. The yielding arm 61' is so disposed that it moves in'a path just below the fixed arm 62.' A stop 66 is provided td receive the yielding arm 61 when the same is swung back against the pressure of the wheel and in which position the arms 61 and 62 aline.
Hingedly secured upon the table 27. at
center of which is cut away to pass the yielding arm 61 and fixed arm 62. and structural parts connected therewith. The end of the plate 68 is depressed to rest upon the bar 58. and is held in its depressed position by coiled extension springs 69. 69 disposed on each side of the plate 68 and adapted to normally force the said plate 68 against the bar 58 so that the carriage 19, andparts connected therewith are maintained in such a position where the yielding toothed arm 61 is in engagement with the bar 58. In this engagement of the yielding arm 61.. the pressure of the spring-5T as exerted upon the wheel forces the said arm 61 backward against the spring 65 and against the stop 66. In this position, as above stated. the yielding toothed arni 61 and the fixed spring 7 riage 19 is the bar-58 the arm 62'-engages the bar 58, so that the carriage remains in a stationary osition during the imprint caused by this toothed arm 62 are in alinement. l/Vhen now, for the purpose of printing, the carto yield to the pressure, permitting the yielding arm 61 to pass below'the bar 58. Before the arm-61 passes out of engagement with epression of t e carriage 1-9. Instantly the arm 61 passes out of engagementjwith the bar 58.the sprmg65 movesv the arm 61 until I arrested bythestop'64l. In this position it will be found that the arm 61 is in alinement with the next succeeding tooth 59 of the bar 58. After'theimprint, the carriage 19 lsallow'ed to rise, lifting the arm 61 into engagement with the bar 58 and with the next succeeding tooth 59 thereof. This engagement between the arm 61- and the bar 58 occurs before the disengagement of the" arm 62 and the bar 58. Immediately the arm 62 passes out of engagement with the bar'58 on the rise of the carriage 19, the
lateral pressure of the carriage, due to the pull of the spring 57,.overcomes the tension of the spring 65 and advancesthe carriage until the arm 61 impinges upon the stop 66.
In this position the carriage is advanced one printing space, and is ready to imprint the next succeeding letter.
= To operate in COIlJllIlOtlOll with the spacing mechanism just described there are provided" two visible tabular spacing indexes 370 and 71. The index 7 O is fixedly mounted upon a rod 72, which is removably mounted the machine during transportation, itbeing more readily packed within smaller compass when the index is removed. At such times the pointer 74 is so moved that the index end thereof is rotated over the plat-- form of the carriage When the pointer 7 4'is extended it will show the printing p'osition of the carriage.
The index 71 is'formedon the'upper edge of apaper guide 76, and corresponds in perfeet alinement with the index 7 0. The guide 76 is provided at the lower edge with a stifiening rod 77 which is preferably mounted in standards '78 78 located at each end of the base 47. Surrounding the rod 77, and
anchored to the base 47, are coiled extensionsprings' 79, 79. The upper ends of the springs 79 to throw the same forward a ainst a platen rollerf80.fl The paper guide 76 is provided withQa fender roller "81 which is mounted in bearing ,t'abs 82,182, mounted upon the de in such manner that the g 8Q, ='extends. slightly be surfa depressed, the plate 68 is forced f whereof the paper,
. therefrom,
bear against the paper guide 76 yond the inner surface of, the paper guide 76. In this manner-a binding strain is prevented from being exerted by the. guide 76 upon the paper and roller 80. Fixedly attached to the guide 76 is an extension 83, whereby the said guide 76 may be swung upon its bearings down andfaway from the platen roller 80. In this position the guide 76 may be locked by a lever '84,'the arm 85 is adapted to throw over. the extension 83 when the same is'idepressed, asabove indicated. This facilitates the introduction of the. paper, leaving the runway between theirollerSO and the paper guidei7 6 free so that the paper can be quickly and readily inserted therein. Vhen the paper is 111- sertedthe lever 84 is thrown back to cause the arm 85 to release the extension83, when the springs 7 9, 79 press the guide 76 against holding the same tightly against the platen roller;80. In this position the pointer 74 is used for corrections or omissions in the printing, very much in the same 'manner as in the present standard typewriting machines. p
The platen roller 80 is constructed of any suitable material, such as" employed at present on. standard typewritmg machines. The roller is fixedly mounted upon a bear ing'rod, at the one end ofwhich is fixedly mounted. a knurled or milled adjusting wheel 87. At .the opposite end of the platen roller 80 is mounted a" ratchet toothed spacing wheel 88. 'Intothespacing wheel 88 is set the tooth of' apawl 89, which is spring-actuated to-snap against the face of the succeeding teeth to thereby gain the roper space to which the roller is turned. he roller 80 is mounted in standards 90,
which are mounted upon a plate slide 05 Attached to the slide 91 and extended are brackets 92, 92. Fixedly mounted in the'bracket'sl92, 92 are guide rods 93,93, The gufie'r'o'ds 93, 93 are extended through perforated brackets 94, 94 setont from the sideof the base 47. Fixedly mounted upon. the inner ends of'the rods 93, 93 are stop blocks 95, 95. Through an eyelet in an extension 96 of the said rods 93, is passed the end of a spiral expansion spring 97. Thejanchored end of the spring 97 is secured to pins 98, 98 extended from the side of the'base 47 It is by .means of this arrangement that the platen roller 80 is shiftedjto accommodate the disposition of printing characters in parallel rows, as, for instance, to form the lower and upper font characters of the type.
The shifting mechanism employed to o'pcrate in oppositiontojjthe spring 97 con- 'sists of levers 99 and The'levers 99 and 100 are fixedly mounted a pivot 1r0d"10 1,--wh'ich is extendedi'a'cross the'mae chine-{and is" pivoted "bearings 1.02,- 102. ""By; arrangement thelj r rs 9 and 100 are operated simultaneously. the said levers 99 and 100. are pivotally connected to links 103, 103. The links 103 are pivotally connected at 101to the standards 90,90, and at 105 to the levers 99 and 100. Due to the arrangement and construction above described, whenever the levers 99 are depressed, which occurs when the operator, by means of lllS thumb or finger pushes down afoot 106 mounted upon the lever 99, the
'. platen roller 80 is shifted so as to receive the type characters of the outer row on the disk 11. As stated, the operation of the levers 99 and 100 and the links 103, 103 are in opposition to the spring 97. The spring 97 normally holds the platen roller 80 in position to receive the inner row of type characters formed on the disk 11. The
roller is returned instantly to this position therein by a suitable spring adapted to snap over the slot 108 when the rod 107 is seated therein. In this position the paper is guided on being passed off the roller 80 to deliver upon the base 17 and to be delivered from the machine under the pivot rod 19 and at the rear of the machine.
With a machine constructed as above described and as illustrated in the drawings,
the opera ion is as follows: To introduce the paper the carriage 19 is raised until the opening between the pivot rod 49 and the rack bar 58 is free. The paper is then introduced under the roller 80, the paper guide 76 having been retracted from the said roller and locked in retracted position. l/Vhen the paper is inserted beyond the upper edge of the guide 76, the lever 84: is rotated to release the extension 83 to permit the guide to move against the paper and hold the same in contact with the roller 80. In this position, and by means of the wheel 87, the paper is adjusted. Therod 107 is removed from the slot 108 and raised until the end of the paper is wound from the roller to extend beyond the rod 107 when the same is depressed. The rod 107 is then depressed, passing it below the retaining spring and seating it within the slot 108, the paper being held below the rod., The carriage 19 is now moved to the extreme left and there permitted to asslime the recumbent position wherein the carriage is supported upon the plate 68. In
' this position the fixedtoothed arm 62 is held between the teeth 59 and the machine is in readiness. to proceed with the printing.
Each of The printing proceeds by the operator shifting the arm 18 untiKthe finder 22 thereon is disposed over the character selected for printing. As above described, the movement 'of the arm 18 causes the disk 11 to move in unison therewith, so that the type pad 12 corresponding to the character illustrated at the point where the said arm is arrested, will be presented above the opening 34, in the inking pad 28. The type, in moving to the opening 34, is wiped by the inking pad 28, and placed thereby in condition to print upon the paper A. The carriage 19 is then depressed by either the hand moving the arm 18 or the other hand of the-operator forcing the pressure foot 39 downward upon the type pad 12 which is alined with the opening 84. The pad 28 being interposed between the type and paper to either side of the opening 3 1 prevents the imprinting of any but the letter disposed above the opening 34, The letter having been imprinted, the pressure from the carriage 19 is removed, permitting the springs 69 to raise the carriage 19 so that the same is allowed to shift the succeeding space, or until the yielding arm 61 is arrested by the stop 66. In this position the carriage is ready to imprint the second letter. The
operation is repeated until the word is completed, when, by moving the arm 18 opposite the blank spaces 109, 109, and co-incidently depressing the carriage 19, the spacing mechanism is caused to operate without the attendant imprinting-of a letter. At the end of the line the carriage is raised so as to remove the arms 61 and 62 from engagement with the spacing bar 58, and again returned to the extreme left hand position on the guide rod 49 and there permitted to resume engagement with the spacing bar 58. The roller 80 is rotated one or more (spaces. as the case may be, to receive the succeeding line. As stated, the knowledge of the movement of the roller 80 is imparted through the click" or sound of the pawl 89 upon the ratchet wheel 88. During the operation, if it is desired to shift the position of the roller 80 forward or backward so thatv the outer line of letters or characters is brought in line. with the crown of the said roller,'this is accomplished by depressing the foot 106, as above described, thereby shifting the roller 80 outward. The letter of the outer row, as for instance, a capital, being imprinted, the operator releases the foot 106 when the springs 97, 97 immediately return the roller 80 to receive the letters on the inner row. i
I have found it convenient in machines of this character to provide themachine with twostyles of type characters. This i'sillnstrated-in .the drawings where theLsection B and the section C are shown as having duplicate sets of letters. In actual practice I prefer tovary the style of these letters, thus giving to the machine a wider scope of usefulness th 11 that possessed by the present make of machines,
