T0, all whom it may concern:

Be it known that 1, LEE S. BURRIDGE, citizen of theUnited States, and resident, of the borough of Manhattan, in the city of New York, in the county of New York and fitate of New York, have invented certain new and useful Improvements in, Type- Writing Machines, of which the following is'a specification.

1 writing machines.

. is a vertical section taken longitudinally. of

' The object of the invention is to produce a full keyboard, front strikewriting ma-. chine, of simple construction and 1nexpen-- sive to manufacture.

The invention includes a novel arrangement, whereby a large number of'typ e-bars 'may be mounted in a small space, this fea-' ture being of special importance .in con structing a full keyboard front strike or other visible writing machine having-eighty. or more type bars, which should occupy less.

than half a circle. I

The invention also includes novel adjustable pivots for the type bars and novel. connections from the latter to the keys.

'My invention consists in certain features of construction, combinations of devices and' arrangements of parts,'al.l as will be, fully hereinafter set forthand particularly pointed out in the concluding claims.

In the accompanying drawings, Figure 1 a full keyboard, front strike-writing machine, made in accordance with my invention. Flg'. 2 1s a diagram illustrating the' relative arrangement of the platen and the type bar pivots. Fig. 3 is a front sectional elevation-taken forwardlyof the type bars I and in rear of the keys, on aboutthe line X X of Fig. 1. Fig. 4 is a front secti0nal. elevation,taken th'roughthe type bars and key levers at about the line Y Y of Fig. 1. Fig. 5 is a diagrammatic plan View of the key lever system. Fig. 6 is an" enlarged:

fragmentary plan view .'of a central portion of the type system, showing a single group or nest of type bars 'and their supports. Fig. 7 is a perspective view of one form of type bar having an integral operating arm.- Fig.'8 is a fragmentary perspective view of the hub. end of one form of type barshowing the operating arm thereof separated from the main. portion..' Fig. 9 is a plan" view of a nest of type bars of the preferred This invention relates to type actions of form. Fig. 10' is a fragmentary plan of a modified multiplex hanger. Fig. 11 is a perspective view of one of the type bars shown at Fig. 9. Fig. 12 is a side view of a hanger arm. Fig. 13 is a sectional elevation similar to Fig. 1, but showing-the typebar actions "at the left-hand side of the machine.

In the several views, portlons are omitted or broken away for the sake of more clearly disclosing the invention, and similar parts are designated by similarnur'nerals of reference.

The framework of the machine comprises siole plates having base portions 1, upwardly extending standards or posts 2, .upon which is supported a top plate 3, said' plates being connected by a'front bar 4; and rear plate 5,

suitable carriage 11 the latter having an escapement rack 12, 1n which work the usual feeding and detent dogs 13 and '14, carried upona rocker 15 which is mounted upon a horizontal rock shaft 16, the shaft having oppositely arranged operating arms 17 from which is suspended by links 18 a horizontal transverse universal bar 19.

The type bar system comprises preferably twelve substantially similar groups of seven bars each, the bars in each group lying side by side and overlapping and being rigidly 1 secured upon rows of transverse parallel pivots 20, the pivots in each row being arranged at such intervals as to cause a proper separation of the types 21 at the ends of the;

bars. .The'types in each group lie in a row that extends longitudinally of the type bars and transversely of the entire system of types, so that said system is made up of a series of twelve rows, the bars in each row being parallel or substantially. parallel. It will be seen from an inspection of 3 that if a series of lines are drawn from the types 21 to the printing point, these lines. 1

will indicate radial planes each of which cuts the printing point and the types" 21 of a group of bars. The pivot s 20, which extend at right angles to the type bars. are of .such length as to project at each side beyond the type bar groups, thus giving wide arranged in a tion of the type bars in radial bearings for the bars. The type bars in each group swing in parallel planes, while the bars in different groups swing in difi'erent angular planes, owing to the arrangement of the groups in whose radius is of a type bar from pivot to type, as illustrated at Figs. "1 and 2. At the latter figure, it will be observed that if all the type bars in a group could be simultaneously in printing position, their pivotal ends would fan out centric to the printing point.

tion relatively to the printing type bars at the center of theentire system standing about vertically when in printin position, and those upon either side thereof standing at gradually increasing lnelinations, until at the extreme ri ht and left hand sides of the system the are stand in nearly horizontal positions when printing. here is one type only on each bar and the types of each group of type bars are all straight line one'behind the other longitudinally and midway of the group, the outer ends of the type bars bemg bent inwardly towards each other from opposite sidesof the median line of the group so as to bring all of the types in said line, and which line in each group is in a plane radial of the printing point. Owing to their long pivots, the type bars at all parts of the system are enabled to vibrate freely and to strike the printing point with accuracy; while owing to the novel disposigroups or nests, a large number of bars may be assethblecl in a comparatively small space, so that the types may lie within easy striking distance from the platen.

Preferably each type bar is divided longitudinally or made in loop form, as illustrated at Figs. 9 and '11, the sides of the loop being indicated as 9 and the forward ends thereof being bent inwardly at 9 and provided at their meeting points with a socket 23 for receiving the shank of the type. The inner or rear type bar may be made either in loop form, as.' illustrated at Fig. 9, or in the undivided form illustrated at' Fig. 6. The other type bars in the group have loops of gradually increasing width, so that the type bars may nest or lie one within anothe in the modification shown at Fig. 6. the tvpebar arms are plain'oru'ndivided. being arranged three on each side of the central type bar,- their extreme forward ends being curved or otherwise bent inwardly at arc whose center and occupy an arc con- Each group of type bars occupies a different radial pos1-' center, the- .bar 26,

emcee 9, so that the type sockets23 may lie in a row or line; but the construction shown at Figs. 9, and 11 forms a stilt'er bar without unduly increasing the weight thereof, the bending stress occurring at the impact of the type being borne evenly by the two sides 9 of the loop, and there being little or no torsional stress thereon.

-From the foregoing description, it will. be understood that the pivots of the various type-bars are arranged in a plurality of vertical parallel planes that extend transversely of the machine and that the various types are likewise arranged in a plurality of vertical parallel planes that extend transversely of the machine and which are parallel and equal in number to the planes in which'the pivots of the type-bars are situated.

The'type ends of'the bars in eachgroup rest upon a cushion 24, which is made in sleeve form and slips over the free end of a forwardly projecting arm 25, whose rear end is shaped to fit upon a curved plate or the latter being secured by cars 28 and screws 27 to the underside of the top plate, and thearms 25, of which there is one for each type nest, being secured to the plate 26 by screws 29.

The'pivots 20 are coned or pointed at each end at 30, and have opposite bearings in parallel hangers or bars 31, which extend horizontally between segments 32 and 33, the latter being' secured by cars 34 and screws 35 to the top plate 3, and curving concentrically with the type system, and the former being iirtlie form of a vertical plate ha ring a horizontal upper edge and forming preferably a part of the general framework of the machine. The bars 31 have opposite heads 36, which abut against the opposing faces of the segments 32 and 33, and are secured thereto by screws 37, which pass through holes in the segments and are tapped into the heads 36, dowel pins 38 being also provided to insure accurate positioning. The segments 33 and 32, taken together with the cross bars 31, form a rigid grating so that there is no liability of the hangers becon'iing displaced or the type bars'deranged, with resulting irregularity of type impressions. The right-hand coned end of each pivot [its in a shallow conical depression or bearing 39, Fig. 12, formed iii the side of the bar or hanger 31, while its left-hand coned end tits in a conical depression formed in the end of a bushing or bearing block 40, which is seated in a hole or perforation 41 in the op posits hunger 81. The bushing may be moved longitudinally or axially within the hole, and hence ad j usted closely to the pivot, whereby the latter is firmiy supported and also enabled to work freely. After their adiustment the bushings 40 are secured in position by set screws 40, tapped into the upper'edge or face of the hanger 31.' Upon releasing the bushing andpushng it to the left, the type bar may be Withdrawn. The perforations 41 for the bushings alternate with the conical depressions 39, the latter being formed, how-ever, only upon one side of each fixed bar 31. a I v In the construction shown at Fig. 10, each group or nest of type bars is supported wholly by an integral four-sided frame, the heads 36 whereof are secured to the segments 32'and 23, and the sides whereof are provided with bearings for the type bars. The

tw'ospiece multiplex hanger, illustrated at Fig. 6,-is, however, preferred, since the arms thereof are separable and sinceeach arm contains bearings for two adjoining nests of type bars, thus simplifying the construction and reducing the cost of manufacture. It will be perceived at Fig 6 that each arm which is interposed between type bar groups has bearings for the bars in both groups.

arm of the outer or forward type bar being i upon the right side'thereof, thatof the next rear orinner type bar upon the left thereof,

and so on, so that the same arms are given a sta gering arangement, wherebyfroom 1S affor ed for the attachment of the links 8.

For the same purpose the undivided tvpe bars shown at Figs. 6 and 8' may-have offset operating arms, as required. In :both constructions the operating arms are arranged (line in rear of or behind-another, asseen at -Referring particularly to Fig. 1, which illustrates the central nest of type bars, it will be seen that the links 8 extend forwardly at'a downward inclination fromthe'type bars, and are pivotally attached by screws 44 to the tips of the upwardly and rearwardly extending arms of the bell cranks. 7 each link 8 being substantiallyin Iinewith the. arm of the bellcrank or sub-lever to which it is connected. Each of said links 8 comprising a hook-like rear end for engaginga hole 43 in the type-bar operating arm, and a plate-like forward end 8 for pivoting upon the screw 44. The seven bell cranks for this group of type bars are divided into three groups, the forward group, which com-.

prises three bell cranks, being connected to the three forward type bars, the second group of two bellcranks being arranged rearwardlyof and. a little lower than the met group and being connected to the next two type bars, and the third group'of two bell cranks being arranged in rear of and lower than the second group and'connected to the two rear type'bars. The links 8 may .either lie in parallelism or separate at their rear or forward ends, as required. The links and bell cranks in'the second set underlie to some extent those in the-first set, and those in, the rear set underlie those in the second set, sov that suflicient room is afforded for the movements vof the several devices, and

also so that the links in-eit'her set may be.

conducted in any required direction from the bell cranks to the type bar operatingarms 42.

The bell cranks 7 are pivoted by means 'of wide hubs 45 upon three transverse hori-' zontal fulcrum rods 46, which at their ends are secured by set screws +17 insocketsformed upon opposite vertical'plates 48, arranged atthe sides of the machine and secured by-screws 49 to the. side walls 1 of the base, said 'hubs'45 being preferably of equal size and of sufficient width to properly space the bell cranks along the fulcrum rods, the latter being arranged one behind and slightly below another and hence in different horizontal and vertical planes, so that the bell cranks are arranged in different tiers,

in one tier being respectively behind and below similar arms in another tier.

The key levers 6 are connected to the forwardly extending bell crank arms by means of upwardly extending ears 50, whose upper ends are perforated at- 51 to engage pins 52 projecting laterally from the bell cranks,

the perforations 51 being in the form of horizontal slots, so as to accommodate the forward and rearward movements of tl-e pins 52du'e to the swinging of the bell cranks upon theirpivots. The ears 50 terminatev at different heights and are arran ed at diflerent points longitudinally of the ey levers, according to the vertical and horizontal positions of'the bell cranks with which they engage. The. key levers dip or are bowed downwardly at. 6* to pass beneath the bell-brank system, and are pivoted at their rearends upon three fulcrum bars, 53, which extend one behind another horizontally across the machine'and are fixed at their opposite ends to the side plates 1, the levers being notched at their rear ends to engage the lower edges ofthe fulcrum the upwardly andforwardly extending arms bars, and-the latter beingvertically slotted:

at 54 to form guides for the levers. Com: presslon springs 55, which bear up against.

tl-e under sides of the levers forwardly of theirfu'lcrums, are arranged in vertical perforations 56 formed in a fixed transverse bar 57. said perforations being tapped-t0 receive screws 58, which pass upwardly thereinto and form adjustable supports for the springs ing bar or plate 57 55, so that the tension of the latter may be adjusted to meet the requirements of each key lever and type bar. The upper ends of the screws may be provided with stems 59 for guiding the coiled springs 55. Secured to the forward edge of the spring supportis a key lever guide comb 60. The forward ends of the levers, which .are provided with keys 61, are guided in a 1 bank of keys 61, and accordingly the keys in said bank are fixed upon rearwardly inclined stems G6, which have forwardly projecting toes 67, guided by the comb 62 and normally resting against the pad 65' under the tension of the spring 55.

By the provision'of a guide comb with a detachable member such as 64 I am enabled to place in the comb key levers of the character shown, which levers could not be placed in the comb if the parts were rigidly connected on account of the projections 50 situated at one side and the key heads at the other side of'the comb.

The forward type bars are connected by the forward bell cranks to levers pivoted upon the forward fulcrum bar 53 and having keys in the rear banks at the keyboard, these key lever's hence being the shortest in tire system. The rear type bars are connected by the rear bell cranks to the longest key levers, which terminate at the front portion of the keyboard and are pivoted upon the rear fulcrum bar 53; while the inter mediate-bell cranks connect the intermediate type bars to the key levers of medium length, which extend to the middle banks of the keyboard and are pivoted upon the middle fulcrum bar The forwardly extending;-

arms of'the bell cranks may be of variouslengths' as required, and the ears 50 placed at corresponding points longitudinally of the key levers in order to secure uniform key movements. The bell cranks at the center of the system are the shortest and of the most obtuse formation, the remaining bell cranks being longer and more acute or having more nearlyierect type operating arms, according to their distance from the center of the system; Sleeves 68 are placed upon the ends of. the rods 46, to prevent sidewise displacement of the several sets of bell cranks.

As may be seen at Fig. 1, the bell cranks or an le lever'which are arranged at the central portion of the machine and directly beneath the lowermost type bars, where -the machine, morc space is lengthened so as to there is but little room between the key levers and the type bars, are considerably inclined, whereby their height is somewhat reduced, and whereby they are also given a better initial purchase upon the type bars at the center of the system, which are the most affected by gravity. That is to say, each of said bell cranks or sub-levers 7 has a rearwardly directed arm which is arranged end to end with its associated link 8 and substantially in line therewith so that together they form a toggle connection for accelerating the type bar. This construction is such that it affords an easy action at the initial portion ofthe key stroke by the breaking of the toggle from a substantially straight-line pc sition, and thus causing the type bar to be accelerated during its entire travel to the printing point. As the type bar system curves upwardly from the central portion of 85 gained between the type bars and key "levers, and hence the upright arms of the bell cranks may stand more erect, and these arms may be gradually bring up the forward ends of the links 8 and avoiding undue inclination thereof. The forwardly extending arms of the bell cranks may also be proportionately lengthened and the ears 50 placed at correspondingly advanced positions upon the key levers. Said ears are arranged at varying distances from the key lever fulcrum, corresponding to the positions and lengths'of thehorizontalarms of the bell cranks, as illustrated in the diagram at Fig. 5. Inall cases the forward movement of the front ends of the links 8 is substantially the same, and the bell crank arms are given such proportions and the key lever ears are so positioned as to secure substan- 105 tially uniform key depressions.

The extreme ends of the type bar system curve rapidly upward, leaving a great space between the type bars and the key levers; but in order to avoid the use of unduly lengthened bell cranks, which would necessarily encroach upon the room required for the'keyboard, I provide at each side of the machine a set of three auxiliary bell crank fulcrum rods 69, the outer ends whereof are secured by means of set screws 70 in perforations formed in the upper part of the bracket 48. These auxiliary fulcrum rods have a-similar arrangement to that. of the main rods 46; that is the second rod is arranged behind and lower than the first, and the third behind and lower than the second, whereby the same advantages are secured as already referred to in connection with the arrangement of the main rods. The bell cranks mounted upon these short rods (39 are connected to the associatedkey lever cars 50 by means of vertical links 71.

The entire system of type bar links 8 fans or spreads outwardly from the type bar opcrating arms, and hence the width of-the entire system of links is considerably in excess of the width. of thetype bar system. The width of the key lever system is, however,

substantially equal to that of the bell crank transmitted directly from the keys through the bell cranks and links to the type bars, and lateral strains bein avoided, whereby free and light action 0 the mechanism is/ insured. Some of the extreme right and left-hand bell cranks may have inwardly bent type operating arms, as illustrated at Fig. 3, so that the links 8 connected thereto may lie more nearly parallel with the planes of vibration of said bell cranks, thus avoid-- ing liability of undue lateral stress upon the latter.

The li k 1 8, whic s pen -the. n rsa bar 19, are guided at their lower portions in cutaways informed in angle brackets 73.

which are secured by screws 74 upon a fixed transverse bar 75. Each key lever is provided upon its bottom edge with a rounded projection 76, for actuating the universal bar, said projections being so' arranged with respect to the fulcrnn s of their leversas to always move the universal bar threugh equal distances, thereby securing uniform motions of the dog rocker. 1 5, which is a desideratum n h class of achines Said iii-ej ction 7 6 extendin threerows across the system of key levers, those in the forward row being formed upon levers which are pivoted upon the forward fulcrum rod 53, those the middle row upon those levers pivoted upon the middle fulcrum rod, and those in the rearrow upon those levers pivoted upon the rear fulcrum rod. The universal bar, which is of sulficient breadth to be operatedby any projection 7 6., is so guided by the-device 7 2 that it moves in substantial parallelism, so that its upper or working surface remains constantly horizontal and its" downward movement is the same in all cases.

In operatiom-a key 61 is depressed, and by means of its lever 6 the bell crank connected to the ear 50 thereon is vibrated. and through the link .8 and arm 42 the-.typebar is swung upwardlyand rearwardly to print. -At'the same time the universal bar is de ressed by h p is .6 up n. t ey e e and through the rods 18 and armed? the dog a rocker is vibrated. Upon the'release of the key, the parts connected thereto ,are returned to; normal position by the springs 55, and

the dogrocker is also returned by a spring 77, permitting the usual advance movement ofthe carriage under the tension of a drivingspring '(not shown). v

'From the foregoing description it will be understood that although the diiferent key actuated levers 6 have difie'rent angular movements the variation of contact between "said key levers and the universal bar at differentpoints widthwise of the bar and at di-lferent points from the front of the machine results in a construction wherein means are provided for equalizing the movements imparted to the universal bar by the different key actuated levers and for causing the universal bar to be taken up or the movement thereof to be started with a uniform extent of depression of the difierent keys, so that the escapement will be actuated. alike by the different keys andthe touch on the different keys will be uniform.

Very many changes may be made in details of construction in'adapting the invention to various styles of machines, and portions thereof may be used without others.

What I claim as new and esire to secure by Letters Patent, is
