ALEXANDER '1'. BROWN, or SYRACUSE, NEW, YORK.

'rrrnwmrme MACHINE.

fo ell whom it may concern:

,Be lt'known that I, ALEXANDER T. BROWN,

citizen ofthe United States, and resident of Syracuse, 1n the county of Onondaga and Stateof New York, have invented certain Writing Machines,. of which the following -isa specification.

'My' invention relates to typewritin'g machines and more particularly to' the type actions thereof.

.Qne or: the objects of my invention is to provide an efficient, visible writing machine wherein about eighty-four characters mayv be employed with a separate type on each type bar.

Another object of the invention is to provide amachine of the character specified :wherein. the parts are so assembled and re- 'lated. that they may be contained in a machine] of a standard size without unduly crowding the parts or detracting. from the efficiency of the machine and wherein the type actions are devoid of torsional strain.

further objectof invention is'to provide anI'efficient typewriting 'machine wherein. the parts may be readily and accurately assembled and wherein certain of the parts can be assembled before they are placed in the machine, thus facilitating the manufacture and reducing the cost of making the machine.

. A still further object of my invention is to provide an efiicient typewriting machine wherein the leverage and extent of dip of the various finger keys is uniform zhroughout the keyboard.

To these and other ends which will hereinafter appear my invention consists in the novel-features of construction, arrangements ;of-parts and combinations of elements to be hereinafter fully described and particularly pointed out in the appended claims.

Fig. 19. is a perspective view of the key-stem guide-plates with one of the keystems shown in position. Fig. 20 is a fragmentary perspective View of a type bar segmentwith the hanger and a portion of the typebarshown in place.

In the various views, parts have been omitted or broken away, to better illustrateother features of the construction. The frameof the machine comprises two end or side plates 1 Which are united by a rear plate 2, a vertically disposed segment 3, cross rails 4 and various other parts which will be hereinafter". described. The rear plate 2 constitutes ,a support for various parts of the structure and is secured in place by headed screws 5, the stems of which pass therethrough and into threaded openlngs .in the lugs 6"whichproject inwardly from the side plates, T he rails'4 are grooved ontheir outer faces for the reception of antifriction balls 7 which are. received within companion grooves8 in a carriage 9 which supports a rotatable platen 10 and carries a rack 11v that is maintained in constant mesh with the gear wheel 12. This gear wheel is provided with a central recess .or chamber 12 in which a. driving spring 13 1 0 is contained and the tension of which is exerted upon the gear wheel to rotate' it and thustransmit a feedmovement to the carriage as it will hereinafter more clearly appear. .Meshing with .the gear wheel 12 is i a nion 14 that carries 'a clutch-section .15,

w ich in turn cooperates with a second clutch section 16 that has a peripheral groove 17 therein that is engaged by the forked end of adepending arm 18. This "clutch-section 16 is splined to the shaft 19 surrounds the shaft 19, and is interposed bewhich has an escapement wheel 20 rigidly secured thereto.- An expansion spring 21 tween the head of the clutch section 16 and the hub of the escapement wheel so that the tension of the spring normally maintains the clutch section 16 in engagement with its coeperating clutch member 15. The depending arm 18 is secured at 22 to a yoke-like portion or frame23 which'is pivoted transversely .of the machine at 24, (as shown in dotted linesin Fig. 1) in order that the arm 18 may vibrate foreand aft of the machine. This'yoke-like-portion has secured thereto an arm 25 which is pivoted at 26 to a link 27'connected'at' its rear end by a pivo 23 to cars 29 that project rearw rdly from a bar 30 that extends transversely from side to si e of the-machine. This bar isylikewise provided withdepending arms 31 at the ends thereof that are pivoted at 32 to the side plates of the machine. A rock shaft 33 is mounted in bearings 34 depending from the carriage and the rock shaft carries a depending crank arm 35 that is adapted to bear on the, forward face of the bar 30. A

. second crank arm 36 extends from the rock shaft into the path of a plunger rod 37 that moves longitudinally in suitable bearings in an end plate 38 of the carriage and is provided at its.forward or upper end with a button or head 39.

From the foregoing description, it will be understood that-a depression of the-button 39 will cause the rock shaft 33 to be'vibrated, thus movin'g the bar 30 toward the rear of Q the machine, irrespective of the position of the carriage. The rearward movement of the bar 30 will cause the yoke or frame 23 to be vibrated, thus moving the depending arm 18 toward the front. of the machine, thereby disconnecting the clutch section 16 from its coeperating section 15 which results in a disconnection of the carriage from the 6 escapement wheel 20 and the carriage is free to be moved in either direction. When, how- 'and therefrom. It will thus bonnderstood that ever, the clutch sections are in engagement,

as shown in Fig. 1, the carriage Wlll receive a step-by-step movement in the direction of its feed during the actuation of the keys,

through the vibration of the feed dogs 40.

The spindle 41 of the combined driving gear and spring drum 1212 is supported upon the rear plate 2 of the machine, as is likewise the frame or yoke 23. Theshaft 19 is supported at one end by a bracket arm or plate 42 that receives its support from the rear plate, whereas the opposite end of the shaft is supported by the segment 3. The feed dogs 40 hereinbefore referred to, are rigidly secured to the dog carrier 44: and are beveled in opposite directions to coiiperate with the teeth of the feed or escapement wheel 20. The feed dog carrier is secured to a rock shaft 15 which turns in bearings in forwardly. extending bracket arms 46 that project from the rear plate 2. The dogcarrle'r is likewise provided with a depending portion 17 to which one end of a spring f18 is connected, the opposite end of the spring be ng secured to a screw 49 that is received within a threaded open'ing in the rear plate 2 and by means of which the tension upon the dog carrier may be varied.' The rock shaft 15 is provided 'with 'ferwardly extending arms 50 that carry a universal bar 51 and this uni ersal. bar is acted upon by the renrwardly extending arms 52 of any o' ilie-bell crank levers '53. These bell cranl. levers are each provided with a bifurcated portion 54 that straddles a knife edge or scale bearing 55 of a bearing piece 56, which latter is secured by screws 57 (see Flg. 2) to lugs '58, projecting inwardly from v the side plates of the machine. Each of the bell crank levers 53 is seated in akerfed or slotted portion 59 of the bearing and is thereof (see, Fig. 11). Each of these openings is adapted to receive the bent'end 61 of a returning wire or leaf sp ring.65, and the opposite-end of each spring is provided with a hook-like portion 66 that is received within the lower end of a strap or link 67. The upper end of each strap, Or link 67 passes over the arm 52 of abell crank 53 is seated over a lug-68 that projects the tension-of'each wire sprlng 65 is exerted -to depress the arm 52 of its bell. crank lever, 'thus tending to move the upwardly extending arm 69 thereof in the direction ofthe arrow adjacent thereto in Fig. 1, and at the thereof. All of the bell crank levers 53 fulcrums or pivotal centers that arein the necting or actuating link 71 that extends ing arm 73 of a bell crank lever 7 3. The

therefore extend from the upwardlyproject .vi'ng links 71 are all situated. in a single ver-, tical plane transverse of the machine and are of different lengths, tliose .near the center the type bar at one side of the segment. In other words, the upper ends of the lmks E5.

'versal bar and feed dogs to be restored to .allel vertical planes and are all situated in greater heights from the front toward the creasing in length as they approach the sides, as indicated in Figs. land 2 of the .drawings. Thus in Fig. 1 the-hnk'havmg same tune, each spring tends-to maintain its bell crank lever on the seator bearing are of a uniform size and are mounted in the same transverse vertical plane and on same' horizontal plane so that a forward movement of the'upwardly extending arm of any bell crank lever will transmit motion to the universal bar 51, thus turning the rock shaft 15 and vibrating the feed dogs toward the rear of the machine. A return movementof the actuated bell crank lever to its initialposition will permit the uni their initial positions through the spring 48 and a letter Space feed movement of they carriage will be effected. Each of the bell crank levers is pivotally connected at its upper end to a con-- fore and aft of the machine and .is pivoted at its forward end 72 to an upwardly'extendother crank. arm 74 of each bell crank lever 7 3 is pivoted at 7 5 to akey-stem which is provided at its upper end with a finger-key or button. The various connecting links 71 to the upwardly extending arms 69 of the rear set or. supportingbell cran 8,111 para single inclined plane. The for-ward set of hell cranks are arranged at progressively rear of the machine and in different transverse rows fore and aft of the machine and it'follows therefore that the connecting links 71* are of different lengths; all of those connecting with the same-transverse row of bell cranks-being, of the same length. Each link 71 is provided with an upwardly extending arm 7 8- that has an opening 79 with a contract-ed outlet 80. and the opening receives a pivot of a substantially horizontally disposed link 81 pivoted at its rear end 82 to a type bar 83 that is pivoted at saw-a hanger85 secured in the segment 3 in a manner to be hereinafter described. The upwardly extending arms 78 on the connectof the system being the shortest and in the shortest arm 78 is one that connects with a type bar at ornear the center of the segment, whereas the link having the longest upright arm 78 is one which connects with are arranged in an are or segment that correthe links 71 are therefore made converging or those near the sides of the system are bent inwardly 1n order to connect withtheir respective links 81 and so that the pull upon the links 81 will be in a direct plane fore and aft of the machine. It will be seen upon arms 69 and 73 of the bell cranks,53 and 73 respectively are parallel and'move in par allel1sm during the actuatigrthereof so that the connecting links 71 move in substantially horizontally planes and a straight forward pull 1s exerted'upon the links 81 to move the type bars to the printing position and this is true throughout the system and no torsional strain is exerted upon the parts whether the action be at the center or at either side of the machine. v

From certain aspects of my invention the upright arms G9 and 73 of the bell cranks 53 and 73 respectively may be regarded in the nature of parallel links which move in reference to Figs. 1 and 4 that the upright parallelism fore and aft of the machine and which may beactuated in any suitable manner to. transmit movement to the type bars.

Each of the bell cranks 73 is made up of an upwardly extending arm 73* that has an aperture at its hub-like portion which corresponds to the cross section of the bearing sleeve '86 on which it is adapted to be re ceived and to be held fast against longitudinal movement on the sleeve by frictional contact. From an examination of Fig. 5, it willbe observed that this bearing sleeve is flattened on one side thereof-as indicated at 86 so that the crank arm '73 will be secured to turn with the sleeve. The lower crank arm 74? of the bell crank lever is made up of two converging side pieces 87 that are preferably struck up from a single piece of sheetmetal and are united by a cross piece 88. The hub-like portions of these side pieces 87 are adapted to be forced upon the hearing sleeve86 and'are apertu-rd tojv it joins the integralcylindrical portion'93 thereof. A metal sleeveor washer 94 has a central perforation 1 which it iisreceived' upon thecylindricagl portion of the'stem and.

rests upon or i's supported by a. shoulder 92 thereof.-.- This sleeve or washer -1 is sheathed atilts up'per face. with a buffer of felt or like material, as indicated at 95;

Each keys.tem is provided with an opening .96 in theuppenend t-hereof'which communicates with a slot' 97 in the side wall of thestem. Akey-lmad 98 has a depending projection or p1ntle99 that has a feather or flange 100- extending laterally therefrom. and the construction of the key head and stem 1s such that thecylindrical portion of the pintle 99 is adapted to be received withyet the key-heads may be removed. atwill The cylindrical portionsof .the" -key, stems openings "101 in the guide'plates 1 102- which are securedby screws 1-03toI-tlie-stepj-like 'p'ortions 1 of the side plates l-Aof. the ma ixcl'iir e; From an examination off-Fig. 1', it q-willbe seen that. inthe normal{position of.

jgether with the auxiliary frame, may be mounted as an entirety in 'the machine 1 frame. The bell cranks 53 may then be seated-in their respective slots in the bearing-56 so as to fulcrum on the knife edges or scale bearings 55 and the springs 65 connected to the'lever arms 52 by intermediate links 67;

Fromlan examination 'of' Figs. 7, 8, and 9, I

it will beseen that the disposition of the parts is such that the crank arm 74 of one vhell crank lever is above that of an adjacent-bellcrank lever andworks between the converging sides 87 of the latter. By these means I am enabled to economize space and to mountthe forward bell cranks 73 and the key stems and heads in straight rows fore and aft of the machine and at the same time to provide a bell crank construction wherein bearing of the sleeve 86 on its affords means for connecting the pivot rod of the various bell cranks upright arms 7 3* reference to Figs. 3 and 9 of the drawings, thus affording a parallel arrangement of the links 71 without interference. It will be seen that in the present instance the, seven keys and key stems of each fore and aft-row are arranged in'a straight-line fore and aft/of to their sleeves at different points in the 'width thereof, as will be understood upon the machine but that, nevertheless, the upright arms 73* of each row are arranged at 1 5 ranged one above theother 1 ;3'5: fici'ent actions. throughout the system.

to separate the type bars of adjacent keys loiand avoids the liability of conflict-between "adjacenttype bars in the basket without a changing the standard keyboard. Thus, for example, the keys for the letters e and id and *E and D are usually arin the sanie fore 'and aft row and these letters are frequently used one after another. It is desirable therefore that thetype bars for these letters he separated toavoid the liability of conflict 2.0 when they. are rapidly operated in succes- -s1on. 'I'am-likew1se, this arrangement,

I aena'bled'to provide an action where there is but little, if any, torsional. strain on the bell crank levers by reason of the elongated widthwise bearing provided therefor andthe disposition of the crank arms on the bearings'leeves. In fact,'the strain exertedupon the parts of each action from the finger'key to the type bar may be said to be BOa-direct' one fore and aft ofthe machine, there being little ifany torsional strain upon. any of the parts, whetherjthe action beat the center or at thesides oft-he sys- Q tern, thereby providing easy,;lrapid and efwillialso be seenthatall of the actuating parts of each action up to the type bar inove fore and aft of the machine in a substantially vertical plane antlth'at the planes'in 40 which. the actuating parts of the different actions are situated are substantially parallel; that the links 71 and 81 are drawer pull links which'receive the strain applied 1 I thereto by the keysin the direction oftheir -leng'ths and that they could therefore, if necessity demanded, be made of very thin and light-stock; that there is no crossing of the-parts except-the bell cranks .73 which I I does not interfere with the operation of i n'iounting or of the-removal of the parts nor detractfrom the efliclency of the machine but on the other hand adds to its efficiency. Furthermore each series ofjbell cranks 53 and 73. kcv'stems, etc., are of a uniform size. By mmiiiting the various bell crank levers l J .specified and connectlng the connecting links 71, bell cranks 53 and key-stems there to. I am enabled to assemble these parts outside, of the machine proper and afterward readily place them in the machine. This as- ,-fsen 1blage or" thepartsis facilitated-by the a-construction.of' the links 81, each of which I 'is' made in the nature of a two-partflink,;as

' shown" in Figs. 1, 4, 6 and ,7, 'o ne member where it is received is an important feature .nietal. with the edges end of an arm 78"of a to constitute a face of the metal I be quicklyconnected or disconnected.

in the auxiliary frame. in-the manner of the link consisting of a rod 121' which is pivoted at one end 82 to the type'bar and the opposlte end of which is threaded at 122 threaded portion 123 of the other section.

This internally threaded portion is struck up into a harreLlike or substantially cylindrical form from a single piece of sheet 123 thereof brought together and terminating at its forward por tion in two parallel. side arms12-l that are spaced apart for the reception of the upperlink 71. The side arms are united by a cross-piece 125 which is formed as an integral part of the side arms andhas anint-egral portion. l26'that is bent downwardly and back upon itself so as within an internally smooth bearing surface by the presentation of a rounded, smooth,-side-surfrom which the piece is struck up for cooperation as a-pivot with the bearingin the armv 78. From an examination of Fig. 6, it will be seen that the relation of this pivot or cross-piece 125--126 to the opening 7 9 and outlet in the exten-' sion or upright arni 78 is such that in the normal disposition of the zontal link'Sl and connecting link 71 cannot become disconnected. When,- however, the parts are turned to aline with each other (a position which they do not occupy during the operation of the machine), they may The threaded connection between the members .5121 and 12% provides for an adjustment of the links to take up any lost motion that may exist between the parts of each action. In other words, each link 81 may be lengthened or shortened at will in order to take up any play that may exist between the parts intermediate the type bar and finger key.

It will be understood from air inspection of- Fig. 1- that the tensionof each spring 65 is exerted to force the buffer or abutment on the cooperating key-stein against the co operating guide plate orlixed abutment 102 so that the tendency of each spring 65 isto take up any lost motion or looseness that may exist between the parts intermediate the type bars andfinger keys-and the machine in operation will be free from rattling at all times evenlf lost motion exists be tween the parts. v

The space bar 127 is connected. to key stems 128 that are pivoted at their-lower ends to crank arms 129 which-project from a rock shaft .130 sup'ported' in bearing brackets 131.- with upwardly extending crank arms 132 .which have'connect-ed links 133 pivoted to theupper ends thereof; These links 133 parts, the hori- This rock shaft is-provided.

correspond in shape to the body portions of I the links 71 "andare pivoted at their rear ends to hell crank levers 1'33} (see Fig. 3), in the same'manner as thehnks? 1 These bell crank levers 133 are the same in construction as the bell cranks 53 and bear on the lower side of the universal bar and-at opposite ends thereof in the same manner as the arms2 of the bell cranks 53 so that a depression of the space bar will. bring about a forward movement of the links 133,

thus moving the bell cranks 133 toward the front of the machine, thereby raising the universal bar and transmitting a feed movement to the carriage in the manner hereinbefore described.

The type bar segment 3 is made up of two sections 134 and 135, both of which are segmental in form and extend throughout the length of the segment. Upon reference to Fig. 13,. it will be observed that the segmental section 134 is provided with a flange 136 on the lower edge thereof which extends throughout the length of the section and takes into a corresponding groove or chan- 1101137 in thesection 135. The section 135 is likewise provided with a beveled flange 138 that extends throughout its length on the upper side thereof and takes within a corresponding groove or channel 139 formed in the section 134 so that the two sections may interlock transversely and thus constitute )ractically a single segment. The section 34 is slotted radially of the printing point at 140, Whereas the section 135 is plain or imperforate throughout its length and is provided with a plane face 141 that con stitutes an abutment for one edge 142 of the stem 142 of each of the type bar hangers 85, whereas the opposite edge 143 of each hanger stem bears against the end wall 144 I l of one of the slots 1.40 in the section 1.34.

' ment between the parts.

' Each Slo 140 communicates with a threaded opening 145 which receives a set screw 146.

thatis adapted to hear at its inner end against the edge 143 of a hanger stem, thus maintaining it in position-in its slot and at the same time exerting a pressure between the two sections of the segment which tends.

to maintain a rigid interlocking engage- The two sections of the segment may,-if desired, be further united by screws which pass transversely from one section to the other and tend to hold the two sections together. It will be observed that the construction of the segment is such that itmay be with little difficulty re dily mounted in place in the machine and that the hangers may be eadily and accurately assembled in place in the segment. ,The rear section 135 of the segment is provided with lateral extensions 147 at each s de thereof which extend to the side plates 1 of the machine and are adapted to be-securcd in place to lugs 148, which project inwardly from said side plates, by

' headed screws 149, thestems ,of which pass through openings in the extensions 147 and .takein threaded openings in the' lugs.

From an examination of Fig. 1, it will be seen that the stems 142 of the various hang ers are alined transversely of the machine and are each provided with a depending lug 151 which is received within the channel or groove 137 in the section 135. It willlikewise beseen that the bearing portions or headsof the various hangers are staggered or project to different extents fore'and aft of the machine. That is to say, every other hanger of one series will have the pivotal centers for the type bars located in a single vertical plane that extends transversely of the machine, whereas the pivotal centers for the typebars of the other series of alternating hangers will be in a vertical plane that extends transversely of the machine and is allof which are of the same 965 may therefore be. provided...

staggered fore and aft of the mathe same distance from the printing center,

for which reason type bars ofa'uniform length may be provided. It will be understood that the arrangement of the various hangers radially of the printing center permits of a radial adjustment of the hangers in their slots, whereas they are accurately positioned in the fore and aft-arrangement thereof and the hangers of each set are interchangeableand no care need be exercised in the positioning of, a particular hanger in a particular place in the segment so long as the hangers of one series properly alternate with those of the other series. This construction likewise provides means whereby any individual hangermay be readily removed withits type bar without disturbing the other hangers or type bars The section 1340f the segment is provided at itsupper ends with threaded openings for the 'recep tion of the stems of screws l52 by means of.

which the forwardly extending plates 153 that overlap the ends of both sections of the segment, are secured in place. The forward ends of these lates receive screws 154' that take within t readed o enings in a segmental, support 155 sheathed with a pad 156 in order to support the .free ends of the various type" bars This segmental support-constitutes a front plate for the machine and extends from side to slde thereof and is united -to the side plates by headed screws 157, the s ems of which pass through the segment and into 'n their normal positions. 12

- threaded openings in he side plates.' Like 139;

screws may pass through the side plates and into threaded openings in the supporting segment, thus notonly maintaining the supporting segment in place but. forminga rigid connection between the side plates at the forward portion of the machine. The plates 153 being rigidly secured in the manner described to the frame of the machine and to'the type bar segment constitute additional means to prevent an upward displacement of the section'l34; relatively to the section 135 and the interlocking engagement between the sections prevents their disconnection in any other manner.

From the foregoing description it will be understood that each of the links 71 is mounted onfou'r parallel axes 70, 72, 55 and 105; that the axes 70 and 72 are movable axes, whereas the axes 55 and 105 are fixed axes; that the construction is such that. the axes 70 and 72 move in directions more nearly horizontal than vertical: that each.

link ('1 includes an upright portion 78 extending abovc'the lowermost portion of the type bar segment, the center of which is in front of the platen and that the links 51 which connect the links 71 with the type bars are connected to the upright portions r- S of the links (1 at elevations progressively increasing from the middle to the sides of the system.

\Vhile many'of the features of my invention are particularly available in a frontstrike or. visible writing machine, I would have it understood that from certain aspects of the invention 'the different feztures thereof are notlimited to a. visible writing machine and that certain features .of the invention' may be used withoutothers.

The paper carriage construction and mounting herein shown are claimed in my application'Sei-ial No. 305,053, filed March 9th, 1906. :The staggered arrangementof the type bars isclanned broadh in another application filed by me on theZIst-fiay of May 1901, and bearing Serial No. 61,206, -the particular construction herein shown and described beingclaimed in the present application.
