COMBINED TYPEWRITING AND COMPUTING MACHINE;
1 Application filed November 80, 1921. Serial No. 518,810.
To all whom/it may concern:
Be it known that I, BURNHAM C. STICK- NEY, a citizen of the United States, residin in Elizabeth, in the county of Union an 5 State of New Jersey, have invented certain new and useful Improvements in Combined T pewriting and Computing Machines, of which the following is a specification.
This invention relates to combined typewriting and computing machines, and is herein illustrated as applied to a bookkeeping machine of the Underwood-Hanson iii machines of the type referred to, depression of the numeral keys efi'ects step -step movement of the carriage in a let ter-feedin direction, and the carriage, in passing t rough a computing zone, acts through a suitable transposition mechanism to so position seriatim denominational bars havin index-pins thereon as to permit digits to %)e indexed in the different denominations in accordance with the numeral keys depressed. The pin-setting mechanism is actuated each time a numeral key is depressed, but no indexing is effected unless a denominational or pin bar has been selected by the carriage cting throu h a suitable transposition mechanism. hen the 80 different digits of a number have been in dexed as described, a general operator is actuated to move the in-bars in accordance with the setting of the index-pins and the corresponding number is added into the 3 re ister.
lhe main object of the present invention is to provide improved transposition mechanism, simple in construction and certain in action. 4 According to the resent embodiment of the invention, the e ective path of the de nomination-selector tappets is adjacent the rear ends of the pin-bars, and, as the movement of the tappet for each letter-space 4 movement of the carriage may be determined as desired, independent actuation of the different pin-bars may be effected with greater certainty than in the usual form of machine, in which the denominational jacks are at letter-space distances apart and the supporting end of each jack or dog is so small that great care must be taken to maintain the parts in close adjustment to insure correct operation.
The tappets or cam members are pivotally mounted on the selectors, so that, when moved past the pin-bars in letter-feeding movement of the carriage, movement of the tappets about their pivots will be prevented and the various pin-bars will be cammed forward in succession, but, when the carriage is moved in the opposite direction, the tappets, upon engagement with the ends of the pin-bars, will be swung about their pivots to ineifective position and will pass idly the ends of the pin-bars. The selectors, with the tappets thereon, may be adjustably mounted on a continuous band, preferably of steel, which may be carried by sprocketwheels, one at each side of the machlne, said sprocket-wheels having pins or teeth mounted thereon at regular intervals and projecting through suitable openings in the band as the latter is fed therearound. To drive the band, provision may be made of a pinion fixed to one of the sprocket-wheels and a rack mounted on the carriage and normally meshing with the inion. It should be understood that the re ation between the diameters of the pinion and the associated sprocket-wheel is such that a letter-space movement of the carriage will effect a movement of a tappet on the lower stretch of the band sufiicient to carry it from effective engagement with one of the pin-bars to effective engagement with the next.
To secure the selectors on the band, the latter is provided, at intervals corresponding to the distances between the rear ends of successive pin-bars, with perforations, and the selectors are provided with slots to receive the band and with openings on the opposite sides of the slot, which may be brought into register with one of the perforations in the band by engagement of wedge-shaped portions of the selectors with notches in the forward edge of the band. When placed in adjusted position, each selector may be secured to the band by a screw passing through the aligned openings in the band and the selector.
To prevent improper displacement of the tappets when brought into engagement with the pin-bars, provision may be made of guiding means to su port both the lower stretch of the ban and the selectors thereon.
Provision may be made of more than one register, and, consequently, of more than one set of pin-bars. When this is the case, the rear ends of the different sets of pinbars are displaced vertically with reference to each other, and the tappets are arranged at different heights on the selectors, so that each selector wlll engage only the pin-bars in the corresponding set.
Provision may be made of a non-compute key at the front of the machine and of a device operable thereby to shift the ends of the pin-bars out of alignment with the tappets, so that no denomination selecting will be effected when the carriage passes through a computing zone.
When the selectors are to be set in adjusted position on said band, the pinion connected with one of the sprocket-wheels is disconnected from the carriage and the portion of the band on which the selectors are to be placed is brought into the upper stretch adjacent to a fixed scale which inclicates the distance at which the selectors for the different sets of pin-bars are to be positioned. The band may be provided with markings corresponding to those on the usual letter-space scale to assist in positioning the selectors. When the selectors are suitably positioned on the band, the latter is restored to its normal position with reference to the carriage and the connection between the carriage and band restored. To enable such connection and disconnection to be effected, the rack may be hinged to the carriage to enable it to be swung out of position to mesh with the pinion with which it usually co-operates.
It will be seen that, according to the present invention, lost motion in the transposition mechanism is to a great extent eliminated.
Other features and. advantages will hereinafter appear.

Figure 3 is a plan view of a portion of the mechanism shown in Figure 2.

Depression of numeral keys l1 and alphabet keys 12 will actuate key-levers 13 and bell-cranks 14 to swing type-bars 15 upwardly and rearwardly to effect typing, by means of types 16 thereon, on worksheets supported on a platen 17. The platen 17 is mounted for rotation in a platen-frame 18 mounted in a carriage 19 which is supported at its :rear for movement 'transversely of the machine on a rail 20.
The carriage 19 is normally urged to the left by means, not shown, and is normally restrained from such movement by means of a rack 21 connected to the carriage and meshing with a pinion 22 having a oneway connection with an escapement wheel 23. As an actuated type-bar 15 nears the end of its effective stroke, the heel 24 there on will engage a universal frame 25 and operate a rocker 26 carrying the usual fast and loose dogs 27 and 28, respectively, thereby permitting letter-feeding movement of the escapement wheel 23 and consequently of the carriage 19.
Each time a numeral key is depressed to print a significant digit, a pin or link 29 connected therewith engages an arm 30 on a shaft 31 of a set corresponding in number to the significant numeral keys and actuates a linkage 32 to ,depress a pin-setting bar 33 thereof. The index-pins 34, which are car ried by the denominational or pin-bars 35, are normally out of alignment with the bars 33, and, except when a pin-bar is selected and advanced by the carriage by means to be described hereinafter, none of the pins 34 will be set upon depression of the bars 33. Upon completion of the indexing of a number, by depressing suitable pins 34 on the pin-bars of a set, a shaft 36 may be rotated in a counterclockwise direction, as seen in Figure 1, by means of a handle (not shown), and this motion may be transmitted, by means of toothed sectors 37, fixed on the shaft 36, to pinions 38, which mesh with racks 39, forming parts of a general operator 40, thereby effecting forward movement of the latter.
In such forward movement of the general operator, a bar 41 thereon will engage the lower ends of depressed pins 34, and advance the pin-bars 35, in accordance with the pins depressed, and, consequently, in accordance with the digits indexed. The pin-bars 35 have one-way driving connections with number-wheels 42, such connections including racks 43 on the bars 35, and, upon forward movement of the bars 35, the number-wheels 42 will be turned in accordance with the digits indexed, the result of the operation being read through a sightopening 44 in a computer-casing 45.
Provision may be made at the rear of the carriage of rearwardly-extending arms 46, carrying a rack-bar 47, on which may be set. at letter-space intervals, tabulator-stops 48, with which vertically-movable plungers or counter-stops 49 may cooperate when raised by tabulator-keys Snot shown). The arms 46 may be extende rearwardly to support a portion of the transposition mechanism, through which the denomination-select ng of the pin-bars 35 is effected. Provision may be made of hinge members 50, secured to the extension of the arms 46, by means of screws 51, and these hinge members 50 may include hinge ins 52, around which extend rtions 53 0? a frame 54, having at its ower edge a rack 55. The rack 55 is normally in operative engagement with a pinion 56, so as to drive the same durin move- I gagement with the ment of the carriage 19 in either direction. The arrows on Fi re 2 indicate the direction of rotation 0 wheels 65 and 69 during letter-feed movements of the carriage.
To maintain the rack 55 in effective enpinion- 56, provision may be made of a fixed arm 57, extending downwardly at the end of the rack adjacent one end of the carriage, and this arm may be gagement with the pinion 56, provision may opening 59 in the rack end is in alignment when the rack is in effective position, this alignment bein maintained by a pin 60 normally exten through said openings 58 and 59. The pin 60 may normally be held-in efi'ective position by means of a leafspring 61 engaging in a groove 62 of the pin 60, and the in 60 may be withdrawn from latching re ation by means of a head 63 thereon, the rack then being released to enable movement thereof out of engagement with the pinion .56, for a. purpose to be described hereinafter. Upon movement of the rack out of eifective position and release of the head 63, the pin 60 will return to normal position and prevent return of the rack 55 to effective position.
The pinion 56 is fixed to a hub 64, to which is also fixed a toothed wheel or sprocket-wheel 65, having beveled teeth 66 engaging in openings 67 in a continuous band 68, extending around the toothed wheel 65 at one side of the typewriter-frame and a corresponding toothed wheel 69 at the other side of thetypewriter-frame. To support the hub 64, provision is made of a boss 70 held on the typewriter-frame by suitable means, such as screws 70, and a pin 71 is passed through the hub 64, a reduced porpin being fitted'into an opening in the boss 70 and secured therein by means of a set-screw 73. At its outer end, the pin 71 is provided with an enlarged head 74, which serves to retain the hub 64 on the pin, and a shoulder 75, formed between the main por tion of the pin 71 and its reduced rtion 72, is at a distance from the head 4 sufficient to receive the hub 64, and to determine the proper position of the reduced portion 72 in the boss 70. The hub 64 of the wheel 69 may be supported by a boss 70 fixed on the typewritenframe on the side opposite that on which the first-mentioned boss 70 is mounted.
It will be seen that the upper dareteh of the band 68 will move in the same direction as the carnage when the rack 55 is in engement with the pinion 56, and that the ower stretch of the band moves in the opposite direction. The selection of the pinbars 35 in the proper order may then be obtained by means of selectors 76, which, in
moving along the lower stretch, will cause tappets or dogs 77 thereon to engage rearward extension 78 of pin-bars 35, to advance the same seriatim, to enablesetting of the pins 34'by means of the pin-setting 11nk' ages. The dogs or tappets 77 inay be so mounted on the selectors 76 that, in p the corresponding extensions 78 of the pinbars, as the carriage moves in a letter-feeding direction, they will be maintained in effective position on the selectors, but, when -moved in the opposite direction past the extensions 78, they will yield, and no advancing of the extensions 78 will be effected. The tappets 77 may be mounted on the selectors 76 in substantially the same manner as the tappets are mounted in the selectors ordinarily in use in' the Underwood-Hanson boo ping machines.
As herein disclosed, the machine is equipped with three registers, each of which includes a set of the number-wheels 42. In order that computations may be efiected independently in the different registers, the rearward extensions of the different sets of pin-bars 35 are arranged in difierent horizontal planes, as shown in Figure 1,-the extensions of the right-hand set being lower than those of the middle set, and the extensions of the middle set being lower than those of the left-hand set. It will be evident that, by arranging the tapgets on different selectors at the proper eights, the set of extensions 78 upon which each selector will be effective can be determined.
The extensions 78 of the in-bars' 35 may be guided near the rear en of the bodyportions of the pin-bars 35 b a slotted member 79. The bottoms of t e slots for the various extensions-7 8 may be positioned so that the extensions 78 will be's'upported thereby in the position shown in Figure 1. In order to prevent lateral deflection of the extensions 78 when engaged by the tappets 77, each set of extensions 78 may be guided in a slotted member 80 suitably supported on the rear of the computer-casing.
Each of-the selectors 76 may comprise a vertical portion in which a tappet 77 is mounted and a horizontal portion or extension 7 6" having a slot 7 6 therein to receive the band 68. At the bottom of each of the slots 76 the selector may be provided with a beveled portion. 81 adapted to seatitself in notches 82 in the forward edge III of the band 68, these notches being spaced at the same distance as the extensions 78 of each set of in-bars, which is the same as the length 0 step movement of a selector for each letter-space movement of the carriage. The pin-bars 35 are formed or spread out at their rear ends, and the pinion 56 is so roportioned with reference to the toothed wheels 65 and 69 that a selector on the band 68 will be moved the proper dlS- tance at each letter-space movement of the carriage.
After positioning the selector 76 by means of a notch 82, the selector is held in position by passing a screw 83 through an opening 84 in the band 68 and aligned openings on the opposite sides of the slot 76*, one of said openings 84 being provided opposite each of the notches 82. The screw 83 is rovided with a knurled head 85 for mampulating the same, and is threaded into the selector preferably on the side of the slot 76 opposite the head 85. It should be understood that the horizontal portion 7 6 of each selector 76 does not extend to the rear far enough to interfere with passage of the band 68 around the toothed wheels 65 and 69.
In order to insure proper positioning of the selectors as they are carried past the extensions 78 of the pin-bars 35, provision is made of suitable guiding means for both the band 68 and the selectors. This may comprise a guide 86 extending across the rear of the computer-casing and supported by each of its ends on the latter by means of a bracket 87. The guide 86 is provided with a slot 88 to receive the horizontal portion of each of the selectors. Since the rear end of the selector engages the rear end of the slot, rearward movement of the selector will be prevented, and-since each of the extensions 76' is rectangular in section and of suflicient width, the rocking of the selector about the axis of the horizontal portion 76 will be prevented. The guide 86 is also provided with a slot 89 extending rearwardly from the slot 88, and of suitable size to receive the portion of the band lying to the rear of the portion which may be embraced by the selectors. It will be evident that by this arrangement proper positioning of' the tappets as they are carried past the extensions 78 will be assured.
As hereinbefore described, by moving the rack 55 rearwardly out of engagement with the pinion 56, the carriage may be disconnected from the transposition mechanism. This manner of disconnection is utilized in connection with setting the selectors 76 on the hand 68, the portion of the belt 68 on which the selector or selectors are to be set being brought into the upper stretch of the band extending between the toothed wheels 65 and 69, and the selectors set by means of the proper notches in the band 68. If desired, the band 68 may be suppliedwith indications to assist in positioning the selectors.
If computation is to be effected in all of the registers simultaneously, the selectors for any two sets must be set a art a distance corresponding to the distance etween corresponding extensions 78 of the corresponding sets of pin-bars. This positioning may be conveniently obtained by means of a scale 90 overlying the upper stretch of the band centrally of the machine and rovided with indications marked R1 2 and R3 which correspond to the registers taken in order from left to right at the front of the machine. As show in Figure 4, the selectors may be marked with numerals'to indicate which one of the registers, numbered from left to right at the front of the machine, is to be actuated thereby. The indications on the band corresponding to letter-space positions of the carriage are shown in Figure 4, and numbers corresponding to the letter-space positions are marked on the band. To support the scale 90, provision may be made of a bracket 91 formed from the same piece of sheet-metal as the scale. The'bracket 91 may be bent upwardly from the rear of the scale and then forwardly to enable an upturned portion at the end of the forward extension to be sccured to the tabulator bracket by means of a screw 92. After the selectors 76 have been set on the band 68, the latter may be brought into proper relation with the carriage by bringing a mark on the band into alignment with a mark on the scale 90, and the rack 55 may be brought into mesh with the pinion 56.
Provision may also be made whereby, upon rearward movement of a non-compute key 93, the rearward extensions 78 of the pin-bars 35 will be moved out of the path of the tappets 77. To this end, provision is made of a rod 94 extending beneath the pin-bars 35 near the member 79, and supported by means of arms 95 fixed on a shaft 96. Upon rearward movement of the non-compute key 93, a link 97 fixed thereto and pivoted to the forward end of link 98 will move the latter rearwardly, and, by means of an arm 99 pivoted to the rear end of the link 98 and fixed on the shaft 96, will rock the latter, thereby swinging the rod 94 forwardly to lift the rear ends of the pin-bars 35 sufficiently to move the extensions 78 out of the paths of the corresponding tappets. When the non-compute key 93 reaches its rearward position, a pin 100, extending laterally from the link 98 and riding in the horizontal portion of a slot 101 in an adjacent member, will drop into the vertical portion 102 of the slot, and the non-compute key will be retained zone in its rearward position until the pin 100 claim:
