To a'ZZ whom it may concern.-

Be it known that we, HERMAN L. WAGNER, a resident of New York, (Brooklyn,) Kings county, and FRANK L. WAGNER, a resident of New York, in the borough of Manhattan, State of New York, citizens of the United States, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

Our invention relates to type-writing machines; and the object of said invention is to provide a machine of the character described wherein the parts cooperate and contribute to the production of an efficient front-strike machine, though obviously the various features of the invention may be employed in machines of different type.

To'these ends our invention consists in the novel construction and arrangement of parts and to the features hereinafter described and claimed.

Reference is made herein to the accompanying drawings, showing one form or embodiment of our invention, and wherein- Figure'l isafront elevation of themachine. Fig. 2 is a detail fragmentary side view of the case-shifting key. Fig. 3 is a like view of the lock arrangement for the case-shiftin g mechanism. Fig.4 is a detail face view of the stripor bar for holding the type-bar carriers in their seat. Fig. 5 is a rear elevation of the machine. Fig. 6 is a plan view of the machine with parts removed for the purpose of clearer illustration. Fig. 7 is a side elevation of the machine. Fig.8 is a fragmentary detail side view of a type bar and carrier at rest, together with some of its cooperating mechanism. Fig. 9 is a detail side view of the type bar and carrier, together with some of its cooperating mechanism, the type-bar being shown in the printing position. Fig. 10 is a transverse sectional view of the strip or retainer for holding the type-bar carriers to their seat. Fig. 11 is a fragmentary detail side View of a ribbon-feed or spool-driver. Fig. 12 is a like view of the same, showing the lockingspring for the shift of the spooldriving mechanism. Fig. 13 isa central transverse sectional view of the machine. Fig. 14

is an enlarged detail fragmentary side view of a type-carrier and some of the parts which cooperate therewith. Fig. 15 is a top view of thesame. V

t The machine is shown with a platen or pa per-roller 1, whose axle or hearing 2 is supported by the side plates 3, united by rods 4, shown with a front wheel 5, Fig. 1, adapted to run on track or rail 6, and rear wheels 7, Fig. 5, adapted to run on track 8. w A spring orfeed drum 9, Fig. 5, tendsto move the carriage, the latter being held or freed for the step-by-step travel by rack 10, engaged by a feed-dog or other suitable equivalents thereof, preferably having the teeth 11, Fig. 7, of which one is yielding or spring-pressed, while the other tooth is rigid, as known. The teeth 11 are shown in the present instance as being carried by a frame'or lever 12 13, fulcrumed at 14 and having slot 15,Fig. 5. The link 16, Fig. 7, oscillates the dog, and this link can be shifted along slot 15 to one side or another of fulcrum 1i to engage either lever arm 12 or 13 for a purpose presently explained. The link 16 is jointed at 17, Fig. 7, to an arm 18 of a vibrating piece or cruciform lever 18 whose forwardly-extending arm is shown at 19, the downwardly-extending arm at 20, and the rearwardly-extending arm at 21. This lever 18 is fulcrumed at 22, Figs. 1, 5, and 13, and its arm 20 is engaged by spring 23, which returns or normally holds the upper arm 18 with link 16 forward.

The key-levers have the usual finger-buttons 21. A n u inberof key-levers are omitted for the sake of clearnes s. The key-levers are shown in form of bell-crank levers, the different arms of each of which are designated at 26, Fig. 7, with fulcrum at 27, Figs. 1 and 5. The arm 26 by the stud or catch 28, Fig. 8, engages one of notches 29 on link or slide 30, the rear or hook part 31 ofwhich en gages the universal bar 32, pivoted to arms 33, secured to rock-shaft 34:, Figs. 7 and 13, having a forwardly-extending arm 35, adapted to be moved by an arm 21 of the cruciform lever 18 When a writing-key is depressed, the arm 26 thereof pulls its slide or hook 31,

with universal bar 32 and arms 33, forward,

for normally holding the lever 37 38 inthe escapeflor feed of the carriage the distanceof. The slides 30, as before stated,

each have a series of notches 29, so as to be adapted for engagement by variously-arranged keys or key-banks. The book 31 of each slide 30 engages the universal bar at the,

rear and is open toward the front of the machine, so thatwhen a hook is moved forwardit pulls with it the bar32; but the forward movement of the bar does not transmit movement of the remaining slides 30. The bar merely passes out of the hooks or out of each hook whose key is not depressed, so that such remaining hooks, with their keys, remain at When released, the bar 32, with the actuated hook, returns or swings back, so as to again enter or be engaged by all the hooks 31.

The spacing key or bar is shown at 36, Fig. 7, the lever 37 38 of said spacing-key being fulcrumed at 39, and the arm 38 engages a laterally-projecting pin 41 on arm 19 When key 36 is depressed, the arm 38 swings arm 19 upward and arm 18 backward to givea thrust to link 16.

It is thus seen that each of the fourarms 18 to 21' of the vibrating piece 18 has 'a function, arm 18 engaginglihk 16, arm 19 is engaged by the lever of the spacing-key,

elevated position.

The slides 30 each actuates its type-bar carrier 45. Each slide has a fork 42, Figs. Sand 9, engaging a stud 43 on the arm or hub portion 44 of the lever or type-bar carrier 45,0arry-i-ng theindependently pivoted or swiveled type-bar 46 with type-block 47, the axis of rotation of said type-bar being at right angles tothe pivot of the carrier 45. When the slide 30 moves forward from the position shown in Fig; 8 to that shown in Fig. 9, the type-bar carrier 45 swings bar 46 to carry type 47 to the paper or platen. The square or fiatfaced type-block 47 can be fixed to the bar 46 and made with a plurality of faces about such bar, two being shown in the present instance, each face having its type or character. By swiveling the type-bars in the manner described the "case-shift is efiected-that is to say, one or another of the plurality of type upon each bar may be made to face the platen and to imprint its character. Each bar has an angular or locking block 48, thefaces of which conform'to the type-block, and a spring 49, pressing against the block 48, prevents accidental rotation of the type-bar and holds the latter so that the required type will squarely face the sheet or platen when printing. The spring 49- likewise forces the type-bar around to the proper position when it is given a partial movement by the means to be hereinafter de scribed. This spring 49, lying along the bar or carrier or parallel to the bar, allows the bar 46 to be turned when required for the caseshift. The swiveled type-bar46 maythushave a partial rotary .motion independent of the motion of thecarrier 45. Such shift is eifected by a shift finger or pin 50, Figs. 6 and 9, which normally lies back farenough or behind the type-bar'carrier 45 to be cleared by the type-bar; but when shifted or slid forward into the path of the fork 51, Fig. 9, at the rear end of bar 46 this fork is carried into contact with'the finger 50 when the type-bar makes its printing-stroke (see Fig. 14) and also during its return swingthat is to say, one prong of the fork contacts with the finger when the carrier movestowardthe printingn i a h the p o g o h f kco-nta t with the finger when the, carrier movesjback to a position of rest, thus restoring the type bar to the normal position, as is clearly rep.- resented in Figs. 14 and 15. The spring 49 assures the proper positioning of thetype-bar, as thefinger 50 moves the type-bar only a portion of the distance through the quarter-turn that it has to make to change case. The bar normally has, say, its small lettersin position to print; but when caught by finger 5O duringthe movement of the type-carrier to the printing-point the bar is turned and the capital or upper-case letter or character faces the sheet or printing-point. As a finger 50 thus not only shifts its type-bar to Write'upper-case characters when required,- but also returns or restores the type-bar to its normal case as the bar returns to rest, a finger 50 after having been shifted into action must be l cked when the type-bar has started toward the printing-point, so that said finger will restore the bar to the normal case position when the bar returns and .not pass .out of action till the bar has returned to'rest. The shifting and, locking of the fingers 50 can be suitably effected, as will hereinafter appear. These fingers are shown mounted on a plate or carrier 52, Figs. 1 and 5, suitably supported so as to slide-as, for instance, by means of a forwardly-extended slide and guide rod 53, Fig.7, and back wardly-extended slide and guide rods 54. This sliding carrier 52 is nor mally held back with its fingers'50 out of action by a spring 55, Fig. 3. An arm or fork 56, engaging the slide 53, extends from rockshaft 57', having arm 58,- Figs. 1, 2, and 6, engaged by loopor strap 59, extending from arm 60 of shift-key lever 61, which is provided with finger-button 62 and is fulcrumed 'at 63-. A depression of key-arm 61 causes arm 60 to move the arms 58 and 56 with rod 53, carrier 52, and all of the fingers 5O forward to a position where they are adapted to catch the forks or tails 51of the type-bars. The play of the arm 58 can be confined in suitable {limits by a stud 64, Fig. 2, on said arm 58,

the stud having its movement or play confined by the fork or stops 65. The rock-shaft 57 also has an arm 66, Figs. 3, 13, and 15, which is provided with stud 67. The universal bar 32 has connected therewith a locking-slide 68, Fig. 3, which is provided with a catch or hook 69, and which moves forward and back with the universal bar at each depression of a writing-key. Suppose the shiftkey 62 has been depressed and the arm 66 thus swung upward and a writing-key then depressed. The universal bar moving the slide 68 forward causes the finger 69 to pass under the raised end or stud 67 of arm 66 and to hold arm 56 with rod 53 and fingers 5O forward or in action until by the release of the writing-key, when the universal bar with slide 68 will move sufficiently far back to allow the hook or shoulder 69 to clear stud 67 and permit the arms 66 and 56 to return to rest.

The ink-ribbon 70, as seen in Figs. 1 and 6, lies normally down or with an edge presented to platen 1, so as not to obstruct the view of the writing or roller 1. When, however, a type is printing, as seen in Fig. 9,the ribbon 70 is automatically turned or twisted, so that the type strikes a face of the ribbon, the

movement of the ribbon being around an axis substantially coincident with an edge of the ribbon. This turning of the ribbon is effected by a holder or fork with branches 71, Fig. 9, between which the ribbon passes. This fork is carried by rock-shaft 72, Fig. 1, an arm 73 of which is engaged by finger 74, Figs. 7 and 9, of a slide 75, connected to universal bar 32, as indicated at 76, to move therewith. As a type prints and the slide 30 and bar 32 move forward the shaft 72 is rocked to turn the ribbon so that the latter presents a face to the platen or paper, as seen in Fig. 9. A return of the universal bar and slide 75 will cause the fork 71, with the front edge of the ribbon, to drop back to the position shown in Figs. 1 and 7, so as to expose the writing.

The ribbon-spools are shown at 77, Fig. 1, one on each side of the machine, and by havin g the spools alternately actuated the ribbon known.

is made to wind or travel back and forth, as The actuation and release of one spool will explain the arrangement of both. Each spool is loosely carried upon a stem or stud 78, Fig. 1, fixed to a disk 79. The stud 78 carries a lug 80,with a springcatch or book 81, which passes through an eccentrically-arranged hole in spool 77 and compels the latter to rotate with disk 79 and stud 78; but such catch or hook can be caused to release the spool when the latter is to be removed.

From the rock-shaft 34, which, as before stated, is actuated by the universal bar, projects an arm 82, Figs. 7 and 11, which engages a lever arm or fork 83, that swings loosely on the stud 78 and carries a depending part 84, Fig. 11, the rim part of which carries a clutch-roller 86. In other words, the parts 8% 86 form a roller-clutch, which when in ac-- tion, will give a step-by-step rotation in one direction to disk 79 and spool 7 7 as the leverarm 82 swings back and forth. In order that the clutch-roller 86 can be moved or set out of action when required, this roller or its axle ends are engaged by hook 87, swinging on pivot 88 on the depending part 84 of the leverarm 83. A spring 89 normally tends to hold hook 87 in position for roller 86 to clutch or engage the rim of disk 79. The spring 89 is also connected to an arm 90 of a lever 91, whose fulcrum 92 is also mounted on depending part 8t. The arm 90 has the step-shaped part 93 and 94. A rotary shaft carries a lug 96, and when the shaft 95' is turned from the position shown in Fig. 11 the lug 96 will press forward the hook 87, and the step or longer part 94t of arm 90 is drawn by spring 89 into contact with hook 87, so as to hold the latter forward in a position where the clutchroller 86 lies idle or out of engagement with its cooperating disk. A further half-turn of shaft 95 causes lug 96 to press back arm 91, so that the step 94 is moved clear of hook 87 which being now drawn or moved by spring 89 backward or to the step or shoulder 93 brings the roller 86 into active position or into engagement with the rim of disk 79. The parts 90 93 94 thus form a combined lock and release lever or mechanism for the part 84.

The shaft 95 extends through the machine from side to side, as seen in Figs. 1 and 5, and has a finger-button or handle 97 for convenient rotation. By fixing the two lugs 96 on the shaft in alternate positions or at an angle of one hundred and eighty degrees to one another the rotation of the shaft can be made to cause the spool at one side of the machine to be clutched or actuated for winding the ribbon thereon, while the opposite spool, being released, is free to have the ribbon unwound or drawn therefrom. .The shaft 95 is arranged to rotate in only one direction and to be locked in the proper positions. Thus fixed to said shaft is the lug 98, Fig. 12, with oppositely-extended shoulders 99. A spring 100 abuts against one or another of the shoulders and prevents a rotation of shaft 95in one direction, and such spring pressing against one face or another of lug 98 holds the shaft 95,with lugs 96, out of action or in vertical position, extending, respectively, up and down from the shaft.

The link 16, it is noted, can be engaged to support the feed-dog at either side of the pivot thereof, accordingly as the feed is to occur eitherjust before or just after a type reaches the printing-point-that is to say, during the printing or return stroke of the type-bar to produce a speed-feed or ordinary feed, as required. The dog-support has studs 101, Fig. 5, projecting within the slot 15 thereof, and the link by its spring 102 is 'held in engagement with one stud or another above or below fulcrum 14:, as required. The slot 15 has an enlarged part 103, which enables the link 16 to be withdrawn or readily disengaged from the dog-support when required. The studs ICC IIO

The hub 44 of each of the type-bar car riers is held forward, with'lugs 113, projecting therefrom, resting in seats 1143. The lock-; ing-strip 115, which, as seen in Fig. 4, has ob ing-studs 117, by which the strip is carried. A proper lateral movement imparted ciently far to clear or release the type-bar car-1 vvriers, which can then be individually slipped.

strip 115 is engaged by arms 118, Figs'l and 5, of lever 118 whose arm 119 is connected to the slide or handle 120, extended laterally in order tnatit may be within the reach of the operator. Moving the slide 120 longitudinally to swing lever 118 will cause the lock ing-strip 115 to move to releasing position, while a spring 121 tends to move lever 118 back to the normal position, so as to press andhold the strip 115 in looking position.

When the universal bar 32 moves forward and away from a number of the-hooks 31, such hooks are held from dropping out of place by the fixed supporting-strip 122, Fig. 8, supporting the rear ends of slides 30. This strip 122 is carried by the fulcrum-support 114 and has lugs 1123, Fig. 1, which support and guide the rearwardly-extendi'ng slide-' rods 54 of the shift finger-carrier 52. .By having the fulcrum carrier or support 114' arranged in the form of a segment of a circle: and the type-bars arranged so that the types are in line with one another or at uniform distance from the end of the bar each type can be made to strike the printing-point or the center of such circle, so that satisfactory work is obtained. Each of the type-bars 46 being held against longitudinal movement by its block 48 and fork 51, the block 47 will remain a constant distance from pivot 113. The strip 115, the supporting-strip 122, andv the carrier 52 are shown of segmental shape corresponding to and parallel or concentric with the fulcrum-carrier.

The front ends of slides 30 are adapted to move in or through a guide or support 124, Figs. 1 and 8, corresponding in its segmental form to the fulcrum-carrier, and the rear ends of these slides are shown guided in the radiating slots of the guide 125, Figs 8 and 10, which guide is preferably cast in one piece with carrier 114.

To prevent too free or a retrograde rotation of disks 79, a brake or friction spring 126, Fig. 6, can be applied to each such disk. The studs 7 8, Fig.1, of these disks are shown fixed in "or carried by suitably-mounted posts 127. The ribbon 70, running from spool to spool, passes over suitable seats'or guides 128, Fig. 6, into which the ribbon can be slipped in order to support it normally in a horizontal position where it extends across the machine, as indicated in Fig. 1 of the drawings. v The-segmental universal bar 32 can be suitably connected to the arms 33 by lugs 129, fixed to the bar 32and pivoted at 130 to said arms 33 of rock-shaft 34.

The motion imparted to the arms 21 and 35, it has been found, is eased by having the contacting face of one of these arms convexed,

the latter during writing and during the shifting of the link to opposite sides of the pivot 14 of the carrier, but the'cut or passage 103 allows the pin 131 tg be withdrawn from the carrier when required, as has before been explained.

Each ribbon-spool catch.81, Fig. 1, when suitably extended beyond its spool 77, can

. be made to serve as a handle for winding or rotatingsuch spool, as well as a means for maintaining the spool in place.

A practical way of mounting the disks 79 is to provide each disk with a long hub or sleeve,'which slips'over a stud 78 on a post 127, and loosely'mounting the spool 77 and clutch-driver or roller-carrying bracket 84 on such hub. The type-bar support 114, as seen in Fig. ,10, is also provided with or has cast therewith an overhangingor forwardly-projecting slotted comb-like guide 132, and as each bar-carrier 45 enters this comb or guide 132 at the time of making the printingstroke a blur of the print by reason of a vibration of the type-bar carrier is avoided. I

The link 16, as seen in Fig. 7-, is made extensible or of parts adjustably secured together, and the link, being lengthened or shortened, can be made to secure proper extent of movement required for the feed action.

The feed of a ribbon-spool or the play of a are not claimedherein, but form the subject typewriter of any suitable or preferred con- In the present instance we have struction. illustrated our invention as applied to a front-strike machine having some of the characteristics of the well-known Underwood machine; but we would have it under-- stood that various changes in construction and arrangement maybe made to adapt our invention to machines of different types without departing from the spirit of ourinvention.
