I To all whom it may mm..-

Be it known that I, GUSTAVE O. DEGENER,

a citiz en-o'ftbe United States,.residin" in New 'York city, in the county of New fork -5 and State of New York, have invented certainnew and useful Improvements in Combined. Type-VVriting and Adding Machines,

of-which' the following is aspecification.

This invention relates to combined adding -10 and typewriting machines, especially those of the class set forth 'in'the pending application of Walter \Vright, No. 485,030 filed March 22,- 1909. In said application the adding wheels are power driven, and their 1 movements are controlled by means ofan escapement mechanism operated by the keys -*and permitting the addingwvheel move ments. Such escapement mechanism operates partly during the down stroke of the figure key, and partly during theup stroke thereof. At the up stroke of the key, the paper carriage is released for its letter-feeding movement, and at'the same time the carriage of the adding mechanism is fed; said adding mechanism being connected to the paper carriage to travel therewith. If'the paper carriage and adding mechanism should feed prematurely, thatis, before the completion of the rotation of the adding wheel, the consequence would be that an error would be made in the addition.

One of the principal objects of the present invention is to prevent all possibility ofsuch premature feeding of the carriage. This might occur by depressing a second key before entirely releasing the first key, or by depressing the key which makes the space between words before completely releasing the figure key, or by prematurely oper- 40 at1 ng aQtabulat-ing key. In any r'of these cases, the carriage would be released for an advance movement and an error would be a made in addition, or the adding mechanism would become liable to get out of order. To

- overcome these liabilities, I provide means movable by any of the figure keys into posi- COMBINED TYPE-WRITING AND ADDING iraonmn-i 5* v s ecification of Letters Patent. Patented Aprl25, 1911, Application filed October 20, 1909. Seria1fio.523,683.

tions to lock .not onlythe remaining figure keys but also any other key that controls the carriage, inclusive of the remaining type keys, the word spacing key and the tabulating keys. 1 1

The invention is shown; as applied to an Underwood front strike writing machine, and the locking of the type keys and tho word-spacing key: ispreferably effected by means of-the same bar thatusually in said machine serves to lock the keys attlie com- 'pletion of the line of writing. Each key le yet in said machineis provided-with a hook, and at the end ofa line of .writing the earriagc causes the locking bar to swing to a position beneath :all of saidhooksor lugs,

so that the keys cannot be operated.

provide independent meansconnected to the adding mechanism for. operating this locking bar. at, every stroke -of the-figure keys. So long'as the .figuref keyisdepressed no other key (that-is. no other carriage feedingv key) can be operated. For thispurpose,

'the levers which carry the word-spacing key are alsoprovided with hooks. Said locking% bar .is usually .mounted upon a rock shaft, and to. said rock shaftis connected a-second rock shaft having stops which are swung simultaneously into thepath of lugs provided on the depressible tabulating keys of the Underwood typewriting' machine, so that said tabulating keys cannot. be operated while-any figure or adding key is in operation. I

Other features and advantages will hereinafter appear.

.In the accompanying drawings, Figure 1 is a perspective view ofthe front part of the frame of an 'Underwood typewriter, showing in normal positions the principal 9 portions of the presentimprovem'ents. Fig. 2 is a sectional side elevation, showing the sameparts asat Eig'.1. Fig. 3 is a sectional front elevation, showing the key mechanism,

and a portion of the "adding devices shown in said application. Fig. 4 is 'a sectional plan of the parts seen at Fig. 3. Fig. 5 is a view'similari-o Fig. 2, showing a figure key depressedto print a figure type, and also showing the locking devices swung to efiective positions. Fig. 6 is a side elevation of a key-controlled escapement wheel and associated mechanism of one form of computing machine. Fig. 7 is a sectional plan of a primary .escapement wheel of the adding scopes mechanism, and key-(:perated means for setting. tlie pinsof sai primary escapement wheel. Fig. 8 is a part sectional elevation ofja primary escapementwheel. Fig. 9 is a sectional plan showing connection to the typewriter eys of .the escapement wheel and appurtenances of the computing mcche tion) containing adding wheels 9 an amsm.

In the ll'nderwoodmachine alphabetical keys 1 and figure keys 2 are mounted u on levers' 3 connectedto elbowlevers 4, the at ter swinging type-harsh against a platen 6 mounted upon a carriage 7. Connected to said carriage, .to travel therewith, is a"car-' riage 8 (marked 159, Fig. 1 of said al'pplicare wheels 10. The'adding wheels are driven by an internal shaft 11 carrying a master.

wheel having two teeth and marked 12. The master wheel shaft 11 is constantly urged in adirection to turn the adding wheels. The' movements of said master wheel shaft are however controlled by the figure keys, .whichfor this purpose are 'connected by vertical links 13, Flgsl 3 and 4, bell cranks 14 and.horizontal links 15 to a universal bar-116, which controls the rotation of' the master wheel shaft. Each link .15 is in the form of a wire extending through a perforation in the universal bar or disk 16, and carries on its right hand end a head 17,-by which it moves the universal bar to the left. The universal bar acts through a lever 18 (pivoted at-19), and link 20,v to swing anarm 21,mounted upon a rock shaft 22,-u'pon which are fixed escapement dogs '23, correspondin somewhat in operation and function tot e escapement ogs of an ordinary typewriter carriage. 'These dogs control the movements of an escapement wheel Said escapement wheel 24 controls the movements of' a variable escape-' ment wheel having a seriesof pins which may be set by the keys. .This variable escapement wheel is connected by a train of gearing to the master wheel shaft 11.

From an arm 26 fixed upon the rock shaft 22 is extended to theleft a horizontal link 27, the inner end thereof, being pivoted to a bell crank having an arm 28 to engage an upstanding arm 29 usually carrying the keylocking bar 30 in said Underwood-machine;

' said bar being supported by a series of arms 31 rising from a rock shaft 32 upon which.-

they may beifixed, such key-locking bar 30 forming part of the usual line-locking mechanism,-'and being, adaptedto catch 'under hooks 33- formed on' the type-operating levers. The'bell crank arm 28 merely bears against the rear edge of the arm 29,a'ndhence does not prevent the operation ofthe latter-by the paper carriage at the end of a line of writing.

Whenever any figure key is depressed the hnk 13 1s. pulled down and thebell crank 14;

is turned, pulling the link 15 to the left, to

gether with the head'17 and the universal bar 'or disk 16, the latter throu hthelever 18 and link 20 operating the roc 'ng arm 21 and rock shaft 22. The arm. 26 on said rock shaft is swung to-the right, and'pulls the link 27 in the same direction, thereby causing the bell crank arm 28 to'swing forwardly and press the lock-bar carrying arm 29 together with the locking bar 30 forwardly to the'position at Fig. 5, thereby looking. all of the type-operating key levers "against actuation. The top of the book 33 is sufiicientlybeveled to enable it"to clear bar 30 during the depression of the key, said bar swinging forwardly over the depressed hook and beneath the other hooks, as at Fig. -5. Upon releasing the key 2 from pressure, the esca-pement dogs 23 are vibrated by a. spring 34 back to normal positions, thereby permitting a rotation of the escapement wheel 24, and hence through suitable mechanism permitting the master wheel shaft 11 .to rotate to a distance determined by the figure key. During such return of the key, the type bar'swings back to normal position, and the locking bar 30 is also-returned to the idle Fig. 2 position by means of a spring 35.

I provide the levers 36 ofthe wordespacing key 37 with hooks 38 to be-intercepted by the loo 111; bar 30, whereby feeding of the carriages 7 and 8, by a premature depression of the word-spacing key 37, is avoided.

To an arm 39, fixed upon the rock shaft '32, is connected the rear end of a link 40: the forward end thereof attached to an arm 41 fixed upon 8. rock shaft 42 and carrying a series of steps 43 normally escapinga series of lugs 44 projecting from the sides of depressible levers 41? carrying carriage-releasing tabulating' eys 46, such as commonly employed on said Underwood ty' ewriting machine. At each depression 0 a figure key, the rocking of the shaft 32 causes 'acorresponding movement of'the arm 39, link 40, arm 41, rock-shaft 42 and locking steps 43, the latter being swung to positions directly beneath all of the locking lugs 44, so as to intercept them, and prevent the depression of any tabulating key 46, and hence any advancing movement of the carriages 7 and 8, until the adding key 2 returns to normal' position, or in other words, until the adding operation is com leted.

The line-locking mec anism of the Un derwood machine usually 'com rises a compound cam 47 engageable by a ug 48 on the carna e 7, said cam mounted upon an adjustab e block 49, the latter supported upon a rocking frame comprising a rack bar 50 and a rock shaft 51. During the travel of the carriage, the has acts upon the cam 47 to swing the rec g frame and vibrate forwardly a pendent arm 52, the latter having a pin or projection 53 to engage an arm 54 erected upon the line-locking rockshaft 32.

The operation of the adding mechanism will be understood by reference to Figs. 2 to 9. The keys 2 pull down the links 13, Fig. 3, to vibrate the .bell cranks 14, and pull the links 15 to the left. Each link 15 vibrates a bell crank 60, and thrusts a jack to the right, the ends of these jacks being disposed in a circle. The ends of escapement pins 6lare also arranged in a circle on a power-driven escapement wheel 62. Any of the pins 61, when projected to the right from the wheel 62, is ready to engage and rotate a four-toothed pinion 63, Fig. 8, which is fixed by ashaft 64 to the secondary escapement wheel 24. They escapement movements of the latter are permitted by the universal bar 16, lever 18, link 20, shaft 22 and dogs 23. The variable movement of the primary escapement wheel 62 is determined by the successively projected pins 61;

but the movement of the secondary escapement wheel 24 is uniform at each computing operation. A fixed cam 65 returns the pins 61 after they pass the pinion 63.

The primary escapement wheel 62 is provided with a bevel pinion 66 meshing with a bevel pinion 67 on horizontal shaft 68, which also carries bevel pinion 69 to mesh with bevel'pinion 70 on the bottom of a vertical computing shaft 71. The top of this shaft carries a bevel pinion 72 to mesh with a bevel pinion 73 which is fixed upon or turns the master wheel shaft 11, the extent of the rotation of said master wheel shaft depending upon the interval between the escapement pin 61 which was last projected by a key 2, and the pinion 64.

The computing mechanism is driven by motor 75, the shaft 76 of which carries a part 77 of a friction clutch, the other part 78 of said clutch being fixed upon a shaft 79 upon which is a bevel pinion 80. This pin ion 80 meshes with a bevel pinion 81, upon a short horizontal shaft 82, the latter carrying at its outer end a pinion 83, which is connected by an idle pinion 8 1 to a gear fixed on the'shaft 86. of the variably-moving primary escapement wheel 62. The pins 61 are held in. both normal and projected positions by a helical spring 87, forming an annulus carried upon the wheel 62.

Whenever the dogs 23 are reciprocated, the wheel 24 escapes, being driven by the clutch 78 and the motor 75. During this movement of 24, the pinion 63 is driven through a quarter of a revolution by the projected in shown in engagement therewith at Fig. 8; and the last projected pin 61 then comes into contact with the succeeding tooth of: pinioni 63, thereby rotating wheel 24 as aforesaid, imtil it is arrested by one of the dogs 23. The movement of the wheel 62 just described is communicated through the gears 66, 67, etc. to the master wheel and to the computing wheels. The escapement of the wheel 24 takes place on the return movement of the dogs 23, that is, on the upstroke of the key 2..

It will be seen that in the present form of the invention, the desired result of preventing accidental forward movenient of the carriage is secured by means of a very simple and inexpensive device added to the usual line-locking mechanism; although the invention may be carried out in other ways, and portions of the improvements may be used without others.
