Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed March 8, 1913. Serial No. 752,900.

To all whom it may concern:

Be it known that I, Hnnnnn'r H. STEELE, citizen of the United States, and resident of lvlarcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Combined Type-\Vriting and Computing Machines, of which the following is a specification.

My invention relates to combined typewriting and computing machines.

One object of my invention is to improve the connections between the carriage of the computer and the typewriter carriage, my improved connections being more especially designed for an open front typewriter carriage. Said connections are, however, useful in connection with some other sortsof carriage than that specified.

Specifically stated, one of my objects has been to connect up the \Vahl computing mechanism with the Monarch typewriter. in carrying out this object, however, I have devised connections and combinations that are applicable or adaptable to machines other than the Monarch and lVahl combination mentioned.

In the accompanying drawings,

Figure-1 is a side elevation, partly in fore and aft vertical section, of a machine embodying my invention, parts of the machine being omitted. I

Fig. 2 is a fragmentary transverse vertical sectional view showing some details of construction.

Fig. 3 is a front elevation of the machine with some parts omitted.

Fig. l is a top plan view of the same.

Standards l rise from said top plate and support stationary grooved carriage rails 5, which through anti-friction balls or rollers (3 support a carriage, which carriage consists principally of a. back bar 7 grooved at its upper and lower-edges to cooperate with the balls 6, and two end brackets 8 projecting forward from said back bar and having a roller platen 10 mounted therein.

The machine comprises a set of printing keys 11 arranged in four transverse rows.

are pivoted to said key levers at 16 and at their lower ends said sub-levers straddle a fulcrum bar 17. The upper ends of the sub: levers are connected by links 18 with type bars 20 which type bars are pivoted in hangers 21 secured to a shiftable type bar segment 22. This segment is shiftable. up and down for upper and lower case writing by means not shown but the segment is guided at its two ends by posts 23 secured to the basel of the machine. Each of the type bars is provided with a restoring spring 24 and each of them has on. its free end two types 25 one of which, in the case of the type bars which are connected with the numeral key levers, is adapted to print one of the digits and the other type is adapted to print some other character.

The types 25 are adapted-to strike against the front face of the platen 10 around which the paper is fed by means which Ihave not thought it necessary to illustrate herein. The type, however, strikeprimarily against an ink ribbon 26 which is wound on two spools 27, mounted on vertical shafts 28 (Fig. Each of said shafts has thereon at its lower end a bevel gear 30 meshing with a bevel pinion 31 mounted on the forward end of a horizontal shaft 32 which at its rear has a bevel gear 33 that meshes with a gear, not shown, on a drive shaft 34 that extends horizontally across the marear arm of the lever 42.

The "gear is connected with said spring drum by a pawl 38 and ratchet 39. T have not shown all of the details :of this ribbon drive as they are .or may be of .ordinary construction well In the Monarch machine known in the art. the shaftiie is usually made'shif-table longitudinally to reverse the direction of the ribbon feed in a well known manner. I

The ribbon is fed past the printing point through a vibrator 4C0 consisting of a ribbon guide that can be slid vertically up and down on a guide all secured to the top plate The vibrator 40 has a part thereof proribbon vibrator lO is thrown can'be varied bymovingthe pin 16 in relatively close to the pivot 48, in which case the vibrator will be.thrown to its greatest extent, and by adjusting said, p-i'ntoward the rear end of the slotas shown in- Fig.1, in which case the vibrator will'be thrown upward to a less extent; :Theribbon shown-in the drawings and commonly used in connection with the computing 'machin'e, :is 'inade or inked in two stripes,liaving a lower stripe a of red universal bar lying beneath all of the key" levers 12' and beingpivoted 1,431 ii -the base part of the machine,

The bi-c-olor mechanism of the Monarch machine has not been fully illustrated herein, as it is of well known construction; but

said mechanism is fully described and illustrated in the patent to Steele No. 1,009,351, dated February 21st, 1911. Said mechanism comprises a sleeve 5d splined on thedrive shaft 3% and controlled as to its position lengthwise of said shaft by an arm 55 which at its lower end isiforkedand enters a pc- .top plate. Said bell'crank is connected by a link 59 with a bell crank 60. pivoted to the under side of the top plate andhaving its forwardly extending arm formed into a handle 61. The construction is such that by moving this handle toward the right the r0d'56 and sleeve 54- are moved toward the right and byinoving said-handle toward the left said parts are also moved toward the left. In the Monarch machine the position of the sleeve is controlled entirely .by "this handle but I have provided other connections between this mechanism and the computing mechanism, as will hereinafter The linkd5 is drawn toward the rear of the machine by means of a spring 62, which spring keeps the said link constantly pressed into contact with the forward surface of the sleeve 54. This sleeve in the Monarchi'nachine is usually made with threesec tions, one concentric 860111011 of small diameter with which-the link 45 is shown in contact in Fig. 1,; thus holding the link' in its rear position to write from the upper stripe of the ribbon; anothe'r section concentric-with the shaft 8 1' but of larger diameter-so thatwhen the sleeve 5+1 is slid toward the left "the link -15 engages this section of larger diameter and-1s moved to ward the front therebyagainst the tension .of its spring62, thusmovi'ngthe pin 16 nearer tothe fulcrum 1-3 and increasing the extent Of 'lllOVGll'lQDl? imparted to the v1- lorator, thus causing the writing to be done from the lower. stripe of the ribbon; and

the sleeve 5-1 usuallycomprises also an cc centric section-63: shown by broken lines in an es-y capenien t whiclrl have not thought it necesare brought out. in the patent to Steele re-f ferred to and T have not. deemed. it necessaryfto illustrate them more fully herein.

The lil'onarch machine usually has a front cover plate 64: whichis secured to the front ripheral groove in the sleeve'54 and which I posts 2 by means-ofsc-rewsho. Pivoted to the backside of this cover plate at 60 is a through which the forward arm of the bell crank passes so that said bell crank and the plate 67 are constrained to move about their respective pivots in uni-son. The plate 67 has indicating marks 70 thereon which show through an opening 71 in the plate G l. Three of these marks 70 are hcre indicated and in the machine these are of such charac-. ter as to indicate to the operator how the bicolor mechanism is For example, one of these marks consists of a spot of blue. an-' other 'of a spot of red and another has a sinu ous line thereon to indicate the automatic cross feed setting of the mechanism.

The lVahl machine comprises an actuator 72 and a carriage 78 on which may be mounted one or more totalizers or adding heads 7 4. The actuator is supported and the carriage is supported in part by a frame plate 75, the lower part of which extends the whole length of theactuator and constitutes the main frame piece thereof and the upper part of which has at the middle of the machine a number of rollers 7 6 mounted thereon for cooperation with the carriage 7 One of these rollers lies beneath the carriage, another is above the carriage and another behind the carriage, and they all cooperate to control the carriage at the middle of the machine. The precise construction of these parts is more or less immaterial so far as my invention is concerned, but the lVahl construction,- or at least a suitable construction, is shown and described in the patent to obster No. 968,103, dated August 23,1910. The frame piece 7 5 is rigidly secured -to the main frame of the typewriter by means of a bracket77 which is secured to the upper surface of the top plate 3 by means of screws 78 and to which the frame piece 7 5 is secured by bolts 79 (Fig. 3) having nuts'SO (Fig. 1') threaded thereon. The means for securing this frame piece to the machine as shown in the present case, is more or less like that heretofore employed in mounting the lVahl machine on the Remington typewriter. In

' the latter case, however, there are two separate brackets, one at each side of the machine. whereas in the present instance there is a single'bracket 77 which includes a connecting bar 81 extending across from one side of the machine-to the other.

therefore made in the form of a truss in or.-

der' to give the desired rigidity tosaid connection. I Said truss or connectingframe includes two side bars 82, one at the right and the other at the left-hand ends of the carriages and, extending forward from the typewriter carriage to the computer carriage.

In order to give these bars 82 the desired rigidity in an up and down direction, each of them is secured to the typewriter. carriage at two points. The platen 10 has a shaft 83 (Figs. 1 and 2), which shaft is journaled 'in sleeves 84 inserted through suitable openings in the end brackets 8 of the carriagewhere said sleeves are secured in place by set screws 85. Each of these sleeves is formed long enough to project a suitable distance outside of the bracket 8 and, at least on the left-hand side, the bracket or bar 82 is formed or provided with a hub 86 which surrounds this projecting sleeve .84.

The Monarch carriage comprises a transverse frame rod 87 mounted above the platen and connected at its ends to ears 88 projecting upward from the brackets 8. A screw 90 passes through each of these ears 88 and is threaded into the end of the rod 87', drawing said rod tightly against the inner face of the ear. The bar 82 at the right-hand end of the carriage is, as shown in Fig. 4, secured by this screw 90 to the outside face of the ear.

In other words, the bar 82 is formed with a suitable holethrough which the screw 90 passes so that said screw not only holds the frame bar 87 in place but also holds the bar 82in place. This bar is therefore connected at two places, namely, at thesleeve 84 and at the screw 90, thus giving it a rigid mount ingon the bracket '8. I v

The left-hand screw 90 in the Monarch machine usually supports notonly the bar 87 but also outside of the car 88 said screw passes through and supports 'a nut-like washer 91 having a reduced part on which is pivoted a link 92 constituting part of the paper feed release mechanism. The left hand bar 82 is mounted on the screw 90 outside ofthis collar or washer 91 and it is partly for this reason, namely, that this bar is spaced away from the bracket 8 by the paper feed mechanism, that the left-hand one of the bars 82 isprovidedwith a hub 86 to space it away from the sleeve 84 correspondingly.

Throughout the greater part of its length each of the brackets 82 is made of angled cross section, as will be understood from the drawing. Each of thesebars thus comprises a vertically disposed part and a horizontally disposed part, the former ofwhich is secured to the typewriter carriage, as has been described, and the latter of which .at its forward end is prolonged and bent into an arm 93 which is connected with the-computer carriage. Preferably this arm is bent,

as shown in Fig. 1, first upward, thence to ward the front of the machine and thence downward, so that each of these arms93 has a vertically disposed ear 9% that lies just back of a plate- 95, which projects outward from the end of the carriage 73 to which said plate is secured by screws 96. Plates of the same general character as these plates 95 are employed in the Wahl machine as mounted on the Remington typewriter, and each of them has a vertically elongated slot 97 therein through which passes a screw 98 threaded into the car 94 and secured by a lock nut 99, Fig. 1. The slot 97 and screw 98 are so related in size and disposition that the carriage 73 is substantially held against motion toward the right and left relative to the ears 9 1 but each end of the carriage has a certain amount of freedom of motion with. relation to said ears in an up and down direction. All of this is fully explained in the patent to Webster referred to.

The double bend in the arm 93, or the angular formation of said arm, as shown .in Fig. 1, enables a suitable adjustment to be made of the ears 9st, both in a front and back direction and also if necessary in an up and down direction by appropriately bending said arm 93, as will be readily understood.

The truss connection between the two carriages also comprises a tansverse' bar 100 situated in front of theplaten 10, as shown in Fig. 1. This bar passes through suitable holes at the forward ends of the vertical webs of the bars 82 and constitutes the front cross bar of the truss frame which connects the typewriter and computer carriages; In order to give the necessary rigidity to the frame, said frame includes truss elements which, while they may be variously con structed, are'here shown as consisting of one or more oblique bars or braces. In the present instance there are in effect two of these bars but inade'of a singlerod 101 which at its 1niddle-part is rigidly secured as by rivets 102 to the bar 100. "The two ends of the bar 101 extend backward and outward obliquely so as to serve. as braces and each of them passes through a suitable hole in the vertical web of one of the-bars 82 a comparatively short distance in front of 'the platen. Both of the bars 100 and 101' are threaded at each of their ends and nuts 103 are threaded on to said bars, at. least two nuts on each end of .each bar, one of said nuts being inside and the other outside of the bar 82. The whole construction is such thatvarious adjustments can be made by changing the nuts 103. Tn asscmbling the -machine all of these nuts are adjusted in such a way as to space the two screws 98 part a distance equal to the spacingof the two slots 97. I I

It is essential, when the typewriter and computer carriages are standing still at some point in an adding ,zone, that the computer carriage be positioned with some nicety in a right and left-hand direction in order that the master wheel may engage exactly with the appropriate register wheel and also in order that some of the other parts may. coiiperate properly and with certainty. 1'1 relative adjustment between the typewriter 'and computer carriages, suihcient to insure the proper position of the computer carriage, can be effected by changing the adjustment of the nuts 103 that are threaded on to the bar 100, leaving the nuts on the bar 101 in the position theyghad at the end, of .the first adjustment. Leaving these latter nuts undisturbed preserves the proper spacing between the two arms 82, and shifting all of the nuts 103 one way or the other on the bar 100 will change slightly the angle which each of said bars will make. with relation to the other parts of the ma chine,-as for eXample any line which represents the direction of travel of the carriages. The forward ends of the two bars 82 will thus be thrown a little to the right or a little .to the left with relation to the typewriter carriage,thus bringing it about'that when said carriage stands at an exact letter space position, the'computer carriage is also with sufficient exactness situated in one of its operating positions.

The line space mechanismof the typewriter includes a line space ratchet wheel 101 which is engaged by a pawl 105, which pawl is operated in a mannerthat need'not be here precisely described by the rocking 'of a. shaft 106. Thisshaft extends inafront'and back direction through and above the left-hand carriage bracket 8, being journaled at its rearendin'an car 107 of said, "bracket (Figs; 1 and at). The forward-part of said shaft is journaled' in a sleeve 108 (Fig. 2) which passes through the bracket 8 and has an arm 110 (Fig. 1) mounted there 7 on and depending therefrom, said arm'having a hub 111 at its lower end with 'a puppet detent or look 112 extending through itand' projecting into one of three suitable holes in the front face of the bracket This arm and puppet or lockare movedin a right and left-hand direction and located in one or another-of said holes, thus rocking an arm 113 which has a bearing on the rear end of the sleeve 108, and the rocking of'. which arm makes a difference in the extentof .feedimparted to the platen at each actulationof the pawl 105. The parts are-pro; vided with a restoring spring 11% and witha handle whichis secured to the forward end of the shaft 106. All of this mechanism is well known in the art and a description of 'itwill be found inthe patent to lifeiritt', no. 791, l83, dated June-0,1905.

I prefer to prolong the shaft100consider- I ably farther toward the front of thema= too - actuator and near its left-hand end in an chine than the regular Monarch construction. To this end I have shown mounted on the forward end of the shaft 106 a collar 115 which is secured to said shaft by a pin 116, said collar occupying about the position ordinarily occupied by the hub of the line space handle or lever. A shaft 117 is secured in'said collar by a pin 118 and said shaft has the line space handle 120 mounted on its forward end and projecting upward after the fashion of the ordinary Monarch line space lever. The forward end of the shaft 117 is journaled in a bracket 121 secured by screws 122 to the inner face of the left-hand bar 82. By the described means thehandle is situated nearer the front of the machine which is a better location for. it when the computing mechanism is mounted on the machine, as shown, as the operator has to reach over said mechanism in order to work this handle or lever.

The adding heads 74 and actuator 72 are of the ordinaryYVahl construction, the latter including a master wheel 123 that meshes with wheels 124 constituting part of the registering mechanism. Said master wheel is.

operated by differential mechanism including a graduated set of arms 125 which are operated by certain cams, which camsare controlled by levers 126, which levers are operated by links 127, the lower ends of which are connected to the several key levers 12 for the numerals or digits. These connec- 125 and the master wheel 123 so as to turn said master wheel one way for addition and another way for subtraction. Said means 111- clude change gear mechanism, part of which is shown in Fig. 4: at 128, and said change gear mechanism is operated by a slide rod 130, which is .supported at one end in the ear 131 projecting from the framework of the actuator. At its left-hand end the rod 130 has a pin or screw 132 projecting through it into a cam slot 133 formed in a convex or arc-shaped plate 134, which plate projects from a sector or lever arm 135 pivoted at 136 to the left-hand end of the actuator. The cam slot 133 includes a middle cam portion and two dwells, one at each end, and it is of such'form that when the plate 134 occupies its rear position shown in the drawings the rod 130 is in its right hand position and the change gear mecha-' nism is set for addition, whereas when the lever 135 is rocked toward the front of the machine the rod 130 is moved toward the left and the change gear mechanism is set for subtraction. The lever 135 has its mo tion limited by a screw 137 passing through a slot 138 in said lever arm and threaded into the end of the actuator. Said lever arm is operated by a key or handle 110 projecting from the forward end of a lever arm 141 which is secured adjustably to the lever arm 135. Said-lever arm 135 is held in its normal position, shown in the drawings, by

means of a restoring spring 112 connected at one end to a fixed part and at the other end to an arm 1 13 of the lever 135. This spring normally holds the parts in position for addition and restores them to that position after the key 110 has been depressed and released. The parts can be held insubtracting position, however, against the tension of said spring by means of a latch 1 1 1. The mechanism just described is the ordinary add-and-subtract change mechanism of the \Vahl machine.

' It is customary in using a combined type,- writer and adding machine to write the added numbers in an ordinary color as blue or black and to write subtracted numbers, including totals, in a distinctive color as red. It will, of course, be "understood that the add-and-subtract mechanism can be shifted by hand and the bi-color mechanism of the typewriter which has been described can be shifted at the same time in harmony with the setting of the computing mechanisnrfrom one character of operation to the other. I prefer, however, to provide an automatic connection between these two parts so that if desired the shifting of one of them will automatically shift the other in harmony therewith. Such a connection has been provided heretofore between the andsubtract mechanism of the VVahl machine and the bi-color of the Monarch machine of such character as to imitate in a way the like mechanism in the lVahl-Remington combination so that operators who have been accustomed to the \Vahl-Remington combination will have no .new operations to learn in using the lVahl-Monarch combination; and vice versa. 7

The connections from the VVahl add-and subtract mechanism to the bi-colormechanism of the typewriter, comprise a link 145 (Figs. 3 and 9) which at its upper end is pivoted to the lever arm 1 13 and at its lower end is pivoted at 116 (Figs. 3 and 8) to the horizontal arm of a lever 147, which lever is pivoted on a rock shaft 1&8 that projects through the cover plate 641 near the lefthand front post 2 and which at its rear end takes a bearing in a. suitable hole in the post 23 which guides the shiftable-segment 22. The construction" is such that when the Key HO moves upward the link 1 15' moves downward, a nd viceversa, so that the lower position of said link vand ofthe' lever arm 1 1? corresponds to the. add'itionposition of the computing mechanism. The leverflldi" has, an upwardly projecting armf150 which is shaped toserve as-a pointer? to indicate the position ot-t'he p'artsand if. desired a suit'ai nle indicator'can be mountecloriformed onthefront taceot. the plate 64: to cooperate with[this-pointer and, with another. pointer 151 (Fig; 7;) that -nor1 nallystands The sleey'e 1'53is a spacingslee-v'e' Which-at its lt'orward end bears against thebmad head of the "screw, 1541 and at its rear end against the ileVer 1 17,".

In these figures lh ave provided at a suitable distance at. one side of the ty pe vriting machine supportingroller or wvheel 170 which as here slioi vn is journaled on a stud bolt 171 having a flange 172 and, passing throughuan up and down slot in a bracket 173 where said stud bolt is secured by means of a nut 174. -An additional wheel of this character is mounted on each side of the typewriter, only one of them. being shown here as they both are or may be substantially alike. The wheels 170 may be supported in any suitable manner but as here shown a bracket 178 is riveted to and projects forward from a truss member or bracket 175 which, as shown in the present instance, is made of ribbon metal bent into the form shown and comprising a horizontal arm that is secured to the top plate 3 ofthe typewriter in any suitable manner and ofan oblique arm 176 that is secured to the lower part of the typewrit'ei frame. As here shown, the horizontal arm of this braceor truss is supported by the screw 78 and also by the screw 177 which connects the top plate 0 with the post 2, this screw being made a little longer than usual for the purpose. The oblique arm 176 of the truss is here shown fastened to the side of the post 2 by means of a screw 178. Preferably the rollers 170 are at such positions at the right and left-hand sides of the machine that when the carriage 73 stands in its. middle position both rollers are beneath said carriage and preferably when said carriage stands in said midde position and is exactly balanced on the rollers76, the two rollers 17 0 would be slightly lower than the lower edge of said carriage. This is-to insure that the carriage runs easily on to the rollers when it. reaches them. It will be recalled that the ends of the carriage have a certain amount of freedom of motion up and down, due to the character of their connections withthe bars 82. v
