Specification of Letters Patent.

Patented July 3, I906.

Application'filed March 13. 1905. Serial 110.249.957-

To an whom it may concern:

Be it known that I, AUoUsTo BONTEMPi, a subject ofthe King of Italy, residing in the city of New York, State of New York, have invented certain new and useful Improvements in Type-l/vriting Machines, of which the following is a specification.

This invention relates to type-writing machines, and more particularly to that class em loyed for writing in books.

I has for its object to provide a machine in which the laten is arranged perpendicular to the line 0 writing and the printing mechanism travels relatively to the keyboard in the direction of line-spacing.

The invention further embodies improvements in platens, paper-clamps, printing mechanisms, inking mechanisms, letter-s acing mechanisms, and line-spacing mec anisms.

Other and further objects will appear in the following description and will be more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view 'of my invention. Fig. 2 is a section on the line 2 2, Fi showing the platen and type-carrier in e evation. Fig. 3 is a top plan view of the keyboard mechanism with the front casing removed. Fig. 4is a front elevation of the keyboard mechanism with the front casing'removed, )arts being broken away. Fig. 5 is a detail paper-clamps. Figfi is a vertical transverse sectional view through the printing mechanism with the type-carriers removed. Fig. 7 is a section on the line 7 7, Fig. 6. Fig. 8 is a plan view of the inking-pads, showing the mounting thereof. Fig. 9 is a section of one of the type-carriers.

' spoctivcly bottom and side views of the third and llrst type-carriers. Fig. 12 is a central longitudinal vertical section of the printing mechanism. Figs. 13,14, and 15 are detail views of the platen-return mechanism, the alarm, and the scale. Fig. 16 is a detail view of the mechanism for throwing .the different lines of type to the printing-line. Fig. 17 is a detail of the platcn-fecd mechanism. Fig.18 is a detail view of the line-spacing mechanism. Figs. 19 and 20 are detail views of the ha[inner-operating mechanism.

Referring more particularly to the draw ings, 1 indicates a. base-plate, enlarged at its per.

view of one of the Figs. 10 and 11 are reprovid ed wit forward end at 2, an upright 3 extending from the rear of the enlargement, and an upright -71 extending from the rear of the base-plate. Spaced above the base plate '1 and journaled in the uprights 3 and 4 isa roller-platen 5, lwhich extends transversely of the printing- Paper or work clamps.-Also journaled in the uprights 3 and 4 is a pair of parallel oscillatory shafts 6 and 7, operated in a manner to be hereinafter described. Slidably mounted on these shafts is a pair 'of work or paper clamps, one for thetop and one for the bottom of the leaf of a book or for a sheet of a- The clamps (see Fig. 5) are compose of a frame 8, which slides on the bars 6 and .7 and carriers near its lower end a roller 9. A

vertically-movable frame 10, havinga key 11 tween the rollers 13 when the rollers 13 are lowered, thereby holding the paper to the platen and permitting its feed in the direction of the line of writing. The frame 10 is notched at 15 and hasa sidewisemovement in the frame 8, so that the tooth16 on theframe 8 may be thrown in the notches 15 by spring 10 to hold the frame 10 at various positions and consequently increase or de crease the'press'ure on the paper.

Printing mechanism.-The printing mechanism comprises three cases of type, each containing twenty-eight characters. The first case embodies all the small letters of the alphabet, the second .the capital letters,,and the third the numerals and various signs, ac-

, cents, &c,., each case being mounted in a separate type-carrier 17 17 17*. Each type-carrier (see Figs; 9, 10, and 11) has two rows of sliding parallel types 18, which are non-circular in cross-section to prevent their turning and are held 111. elevated or raised pOS1- tions by coiled springs 1'9.- The type-car-' riers are provided with openin s 20, one above each type, and on their si es they are grooves 21. The three; typecarriers are mounted on a carrier-support 22,.

, (see Figs. 6 and i12,)'side by side, and are adapted'for movement in the direction transverse to the axis of the platen, this movement being permitted by the grooves 21, in which work the guides 23 on the support 22.

Depending from the frontand' back of the,

carrier-support 22 are guide-arms 22 in which work the ends of two oppositely-disposed U-shaped frames 22", each of which embraces one end of the series of type-carj riers and under the action of spiral springs 22 alinement.

serve to-normally hold the type-carriers in; The, carrier-support 22 is sup-' ported by means of guides 24 from a print ing- Inechanism carrier. isin'carrier (see Figs. 2, 6, '7, and 12) comprises a fixed sleeve 26 and an oscillatory sleeve 27, connected so as to travel together. The oscillatory or cam sleeve 27 is provided with a cam or helicoidal groove 29, in which works a projection 30 on the top of carriersupport 22, and when the sleeve 27 is turned carrier. rier -is anupright 31,

by a means hereinafter described the typecarrier support, together with the.typecar riers, is caused to move longitudinally of the platen relatively. to theprintin -mechanism Extending-.11 wardly om the cariiaving across-bar 32, which connects a pair ofsleeves 32*, sliding on the oscillatory shafts 6 and 7, before mentioned. The shafts 6-and 7 are longitudi- -nally rooved at 6 7*, while the sleeves are provi ed with feathers 33, which cause the sleevesto oscillate with the shafts, but permit themto move axially relatively theret o; Each sleeve 32' has extending therefrom a typecarrier-positioning arm 34 34 one being positioned at each end of the type-carriers in a position to strike and move the type-carrier located over the prin ting-point. Also mo unted by means of lateral perforated arms 35 on the upright 31is a sliding hammer-pin 36,

held in a raised position over the printingoint by means of coiled spring-37. 'This iammer-pin is adapted to be struck by the tappet-arm 38 on a sleeve 39. The sleeve 30 is carried by a shaft 40; which is located to one side of and below the shaft 7 and is longitudinally grooved at 4]. to permit a feather 42 on the interiorof thesleeve39 to travel longitudinally of the shaft, butto cause the sleeve to turn with the hammer-shaft. The sleeve 39 is prov ded wiih an annular groove 43, in which a lug 44 on the fixed sleeve 26 projects and causes thetappet-arm to travel p with the printing mechanism. 2

I Line-spacing.-The printing mechanism is caused'totravel relatively to the keyboard in a direction transverse to the vr'inting-line by means of a screw-shaft 45, which extends through sleeve 26, the sleeve 26 having an internal pro3ection .46, which takes into the threads of the screw-shaft 45. The forward end of the screw-shaft/whieh is journaled in the upright 3, (see lfig. 18,) is provided with a The printing mechantoothed wheel 47 Adjacent the toothed wheel is mounted on the upright 3 a slide bar v48, provided with a key 49 at its upper end and carrying a yielding rack 50, which when the bar 48 is depressed is thrown into engagement with the toothed wheel 47, causing the rotation of the screw-shaft and a consequent advancement of the printing mechanism. The slide-bar is returned to'an elevated or normaLposition by a coiled spring 51 and in returning the'rack being pivoted at 52 rides freely over the toothed wheel) 47. To secure a variable line-spacing, the pin 53, which limits the downward move ment of the slide-bar 48 and together with the pin 54 acts as a guide therefor, is adjustable in the. openings 55.

Positioning type over printtng'p0int.The cam-sleeve 27 which determines the line of type of the typecarriers to be positioned over the printingdine, has extending there through a shaft 56, which has a longitudinal groove 57, in which a lug 58 on the interior of sleeve 27 works. The groove and the key permit the sleeve to move axially on the shaft, but to. turn therewith. As the camsleeve 27 has connectioir. with the carriersupport 22 by me ans of the helicoidal or cam groove 29 and the projection '30, the shaft 56 in oscillating causes the carrier-support 22 to be shifted and one of the lines of types other than the first (which is normally over'the' rinting-line) to be shifted to the printinghis. The shaft 56, which causes the movement, is journaled in the uprights 3 and 4 and at its forward end, on the rear side of the u right3, is provided with a inion 59, with w iich meshes a segmental rac 60 on the end of a bell-crank lever 61. The bell-crank lever 61 (see Figs. 2, 3, 4, and '16) is ivoted at the juncture of its two arms to the rear of upright 23 at 61 and at its lower endis providcd with a curved cross-piece 62, provided with three lugs 63*, 63 and 63. Also pivoted at 61 is a pair of levers 72 and 73 for gaging the bell-crank lever before the other,

thereby causing the shaft 56 to be oscillated to different positions and throwing different cases into printing position, where they may be 'engaged by the type-carrier-positioning arms 34 and 34 As before stated, the front line of the first case is normally over the printing-line, and when either'ofthe keys 74 or 75 is depressed the front line of its Case is thrown to the printing-line. To obtain the upperline of any case, there is located below' which serve to permit certain of the key-levers 82, corresponding to the type of the first line of each case, to move without operating the universal bar, while the other key-levers rest against the bar 70. Upon every depression of the bar it depresses one end of the le' ver 66, elevates the beveled end 64 of the arm 65 into engagement with one. of the lugs 63 63 63 (depending upon which case is in position,) and causes the case in printing position to be moved so that the second line of type is over the printing-line. I

.The key-levers 82 (see Figs. 2, 3, and 4) are ivoted on the pivot-bars 71* and 71 onelialf, or fourteen, on each bar." Each has extending upwardly from its rear end an arm 83, carrying at its upper end a head 84, curved on an are having for its center the ivot-bars 71 71 These heads 84 of each eylever group are of different sizes, so as to be located different distances from the swinging plates 85* 85 one of which is common to each group of key-levers. The swinging plates are journaled at 86 on horizontal axes rying lateral pins 88.

and have extending therefrom arms 87, car- Each of these ins 88 I engages with a crank-arm 89 on the s afts' 6 or 7. It will thus be seen that on every depression of a key-lever the arm 83 thereofengages one of the plates or 85*, swingingthesame and causing the rockin or oscillation of one of. the shafts 6 or 7, w 'ch in-turn swings one of the type-'carrier-positioning arms to engage the type-carrier. positioned over the printing-point and move it trans- 'versely of the axis of the platen a distance.

depending upon the key 0 erated, the distance being determinedby t e distance ofthe head 84 from the plate 85 or 85*.

isaccomplished by means-of a second universal bar 90 (see Figs. 4, 19, and 20) of U shape swung from the pivot-bars 71 and 71". his universal bar extends under all the keylevers 82 and is moved by all of them.

has depending from it a curved arm91, which near the. end of the movements of the ke levers engages with an arnr92 of a be 1- crank lever pivoted at 93 to the front face of the upri ht 3. The upper arm 94 of this bell-cran lever is provided with a pin 95, Working in a slot 96 in an arm 97 on the hammer-shaft 40; Thus the hammer-shaft is rotated, causing the movement of the tappet-arm 38, which forces the hammer-pin 36 against the upper end of the type that is disposed above the printing-point. So that the force of the blow of the tappet-arm may be varied, the universal bar 90 is provided on one or both of its'arms with a depending lug 98, and the upright 3 has passing through it an adjusting-screw 99, adapted to be struck by the lug 98 to limit the downward movement of the universal bar 90.

PZaten-feed.Upon the front end of the roller-platen 5 are mounted a large inner pinion 100 and a smaller outer pinion 101, with which mesh, respectively, a small pinion 102 and a large pinion 103, which are mounted on a fixed shaft 104,1ocated above the platenpinions on the front face of the upright. Housed within the large pinion103 is a platenreturn sprin 105, one end of the spring bein secure to the pinion 103 and the other end provided with an annular series of numbered pin-openings108, forming the scale. Within eing secured to shaft 104. .Turning', with the pinions 102 and 103 isa disk 106,"

these pin-openings is ada ted to be fitted a v pin 109 to provide an a justable marginhl i stop, the pin engaging with a fixed projection" 110 on the frame. pinions 102 103 and disk 106, and a springpressed striker therein engages with the projection 110 on the frame when the end of a line is reached. Below the pinions 100 and 101 is mounted a pinion 112, which carrie an escapement-wheel 113. The escapement- A bell 1 1 1 also turns with wheel 1 13 is controlled by a dog 114; which is pivoted at its lower end at 115 and at'its u er end carries a yieldin tooth 116 and normally held inthe path of the teeth on the escapement-wheel by means of a spring 118. Every time that the universal bar 90 is depressed a depending cam-arm 119 ongages with'acam extension 120 on the dog 1 14, and moves the dog so that the yielding a tooth 116 is out of the plane of the escape ment-wheel, While the fixed tooth isithrown into the lane thereof,.-to prevent its movementf of the path of the escapement-wheel, itif'i'ses slightl under the action of its spring 116 and w en the universal bar 90 isreleased the do 114 moves. to normal position, arid the yie ding tooth 1166s in a positionin advance of the tooth of the escapenient whichiit be-' fore engaged. The escapement-wheel under the action of the spring 105 is now advanced,

the tooth 116 yielding toperinit an advance,

space, this being accomplished by a key-lever 118, the end 119 of which is normally out of the path of the escapement-wheel; but

when the key-lever is depressed it is elevated and engages one of the teeth of the escape- -meant-wheel and moves it back one space.

Thisback feed is adavantageous for corre'c tions' and accent-marks." The other means for reversing the. feed comprises a sliding rack-bar 120, having a key 121 at'its up er end and positioned on the upright 3, so t at it will engage .with pinion 102 and pinion 112. It is obvious "that if the rack-bar 120 is depressed the platen will: be returned to normal osition. 7

means of a plate 122, carrying inking-pads 123 123 ,The plateis bifurcated at its rear end and is pivoted at 124 to a depending portion 125 of the printing-mechanism carrier, being held normally up against the printingface of the type in the type-carriers by a leafsprin 124?, The front and rear type-carriers 17 an 17* are provided with beveled lugs 126 and 127. When the rinting-pads' 123F123 are against the faceo the type, these beveled lugs rest inopenings 128 and 129, through the latter of which the type are projected, it being disposed over the printing-point. When the type-carrier support.22 is moved longitudinally of the axis of the platen 5v to dispose any line of type (other than the'first line of the first carrier) over the printin -line, the lug 126 rides out of opening 128 an into longitudinal pathway 130 between the inkingmovement of the carriers. If the type to be used is in the first line of the first carrier or .for this reason a lateral pat way 131 is pro- I methods is employed, power is stored --up in return-spring l05. The printing mechanpads, therebydepressing the plate 122 awayfrom the face of the type and permitting the the last line of the last carrier, neither of the lugs 126Lnor' 127 would be in athway 1 30, and

vided, so that a depression of the pads away from ,the type will takeplace.

General operation.-A book is fitted below the platen 5, as seen in Fig. 5', with the center of the binding to one side of the platen. A

leaf is then passed over the platen between the platen and the work-clamp, This may be done by turning the knob 1'32, carried-by the bell, depressing ,key 121, 'or elevating the work-clamps and feeding the sheet through by hand. 'If either of the first two ism is movedfjto the rear of the machine by sea,

I a ing mechanisinrf lhe type are inked by sci turning shaft 45 or by exerting a rearward pressure on the printing mechanism. The

lower line of type of the lower case is then disposed over the printing-line andthe writing is started. Upon the striking of every character-key the printing mechanism is first impression is made. About this time the depressed key is released, whereupon the printing mechanism returns to normal osition and the platen with the sheet is fed orward' one space. The space between words is obtained-by strikingfiikeyfF w d, which is piv oted on pivot-bars 71 and 71 and bears on universal bar 90. A back space is obtained by strikin key 118 .When the end of a line is reac ed, key 121 is depressed to return i the platen and the paper to positions to start a line and key 49 is depressed to movethe printing mechanism toward the front of the machine the space of one line. This operation is continued until the writing upon the sheet has been completed. v
