TRANSFER AND. INDICATIRGMECHANISM FOR CALCULATING-MACHINES.
Patented March 6, 1906.
' In the drawings the numeral 1 designates a U-shaped frame which supports between its extended portions a longitudinal shaft 2, held in fixed relation to the frame by a set-. screw 3, bound u on one end of the said shaft. It is to be un erstood, however, that the shaft 2 may be supported 'in any suitable manner and that the frame 1 may have any suitable shape and is supported in operative relation to any suitable form of o erating means. Arranged on the shaft 2 an loosely mounted are a plurality of indicator or numeral wheels 4cut away on each side to form -laterally-extending rin -like portions"5 and" 6, except the last whee to the left, which is constructed 'without the ring-like portion 6. The symbols or numerals are preferably arranged upon the outer surface of the rin -like portions 5 in an suitable manner. ach wheel 4 is formed with an interior star-wheel 7, adapted to be engaged by a pawl 8, mounted upon a pin 9, projectin from and carried by an integral collar 10' o a, collar ortion pro'ects within the ring portion 5 of the numeral-wheel 4. Each numeralwheel 4 is formed with asleeve 12, which supports it about the shaft 2, and upon this sleeve is loosely mounted the ear 11. The gear-wheel is so constructed t at the inner sides of its teeth bear against theouter edge of the ring-like portion 5, and each of the sleeves 12 of the numeral-wheel are enlarged at one end, as shown at 13 in Fi 2, which enlarged portion bears against t e next adjacent ear-wheel 1 1, thus holding it within the ringike' ortion 5 when the'parts are assembled on t e shaft 2. The pawl 8 is held in contact withthe teeth of the star-wheel 7 by a curved spring 14, havin one end pivoted in the collar portion 12 an, its free end in engagement with the pawl 8.. It is obvious that by such an arran ement the numeralwheels may move in ependently of each ear 11, which other or that by impartingmotion to one the V other may be moved therewith;
Each numeral-wheel 4'is provided with a ring of gear-teeth 15, which areiadaptedto be.
" the sides asfwell as'their tops; Such a con contain ten teeth or a multiple of ten, the' number of teeth in the ring and upon the gear 11 being the same.
For the purpose of transferring additions from onenumeral-wheel to the other I arrange upon the frame 1 a counter-shaft 16,
starting at the right each comp u on which are loosely mounted a plurality of transfer-wheels 17. The transfer-wheels are each formed with two rings or sets of gear- teeth 18 and 19, respectively, there being preferably twice as many teeth in the ring 18 as there are in the ring 19, thus cansin one of the teeth 19 to lie in line with eve 0t ier tooth of the ring 18, as clearly set fort in Fig. 6. The' transfer-wheels 17 'are disposed so that the ring of teeth 18 mesh with the teeth of the gear-wheel 11 and that portion of the peri heries ofthe transfer-wheels lying between t e teeth 19 will normally-contact with the outer periphery of the ring-like portions 6 of the next adjacent numeralwheel, as clearly set forthin the drawings.
It is obvious, owing to the distance between each of the teeth 19, that when a ortion of the periphery of the numeral-whee 17 lies in contact with the ring-like ortion 6 a tooth 19 will stand on each side 0 the point of contact, and thus lock the transfer-wheel against rotation. It is also obvious that the transfer-wheels form the only means of transferring motion from one numeral-wheel to the other.
In order to transfer the addition from one numeral-wheel to the other, I provide upon each of the ring-like portions 6 a bifurcated lug 20, adapted to receive one of the teeth19,
and whose furcations 21 extend a suflicient distance beyond the tooth 19 to straddle and enga e one of the teeth 18, it being under stoo that the teeth '18- have a greater length than the teeth of the gear-wheel 11, thus allowing the furcations 21 to engage the said teeth 18. The ratio between the numeralwheels being'one to ten, it is ap arent that hate revolution of one of the numeral-wheelsmust move the next succeedin numeral-wheelone-tenth ofv a revolution. hus'when ten units have been added on the first numeral-wheel the next numeral-wheel is inoved one-tenth of a revolution, thus indicating the amount of the addition. During the revolution of the numeral-wheel the transfer-wheel 17 is locked against rotation, as previously described,
lowing tooth 19 into the bifurcated lug 20.
The continued moving of the numeral-wheel completes the movement of the transferwheel, the following fur'cation bearing against the tooth 19 until the latteris carried to the position shown in Fig. 7, at which point the bifurcated lug rides away from the tooth and the parts are in position to start another transfer. As before set'forth, the numeralwheels each being provided with twenty teeth and the gear-wheels 11 each being provided with twenty teeth it is obvious that when motion is transmitted to the transfer wheel or wheels the ear-wheel is moved the distance of two teet which is one-tenth of its entire revolution.
It is to be noted that owing to the starwheel and pawl construction each numeralwheel 4 may be moved inde endent of the,
adjacent transfer-wheels an the numeralwheels to the right and left until it hascom leted one revolution, when its-bifurcated ug 20 will mesh with the transfer-wheel and operate the same as described to transfer the addition or revolution'to the next succeeding numeral-wheel.
The operation may bebriefiy stated'as fole suitable operating mechanism ,lows: T with which the teeth 15 may be connected being 0 erated to effect the addition, one or more 0 the numeral-wheels 4' are rotated, according to be ma 'e. -As motion is imparted to the nu meral-wheels they are moved step b step until they have com leted. afull'revo ution', when thebifurcated Yugs 20 will contact with the transfer-wheels and carry the addition the value of the addition'sought to from one wheel to the next succeeding wheel,
thus setting up the addition.
1 wish a to be understood that although 1', preferably have. designed my invention to be used in connection with a type-writer or other manifolding-machine I may appl the same to any formof machine or motor when,
in its use would be both advantageous and.
efficacious and that various changes and alterations may be made without departing from the spirit of my invention.
In Fig. 1 of the drawings I have shown the second numeral-wheel 4 to the right provided with a collar portion 22 between the portion 6 and the ring ofgear-teeth 15. Such aconstruction produces a considerable space between the ring-like portions 5 of the second and third numeral-wheels from the right. Thus when the addition is set up the last two digits or numerals in line to the right are separated from the other numerals a pearing on the left-hand side of the space, t e s ace serving as a decimal-point to indicate do rs and cents. It is obvious that by such an arrangement the result of repeated additions be readily read, and it is also ap arent that the .collar22 may be omitted and t e numeral-wheels constructed one like the other, except the last wheel to the left, which, as has been hereinbefore stated, is formed without the ring-like portion 6.
Havin now full described my invention,
what I c aim, and esire to secure by Letters ed to impart motion to the numeral-Wheels,
and a transfer mechanism in engagement with the teeth of the gear-wheels a a ted to transfer motion from each numeral-w eel to portion of the gearthe wheel of a higher order.
2. In an adding device the combination with a recessed numeral 'wheel provided upon its outer periphery with a of fixed teeth free from engagement with-0t er parts of the device, of a gear-wheel connectionwith the recessed portion 0 the numeral-wheel so as to impart motion thereto or to allow the numeral-wheel to move independently thereof, and a transfer device en-' -g the teeth of the geanwheel.
, 3. addin device comprising a recessed numeral whee formed with an internal ratchet, a gear-wheel having a portion projecting into the numeral-wheel, and a springpressed pa'wl carried upon the said projecting heel and engaging wit the internal ratchet.
, In testimony whereof I afiix my signature in presence of two witnesses.
