ADDING-MACHINE.
To all whom 'it may' concern.'
Be it known that lI, ANDREW Rawson J EN- NINGS, a citizen of the United States, residing in the city of London, England, have invented certain new and useful Improvements in and Relating to Adding-Machines, and do hereby declare the vnature of this invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement.
This invention relates to adding machines for use in recording sums vof money or the like in columns and for listing the amount of checks, drafts, notes and the like, adding the ith the foregoing and other objects in View, the invention consists in the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated'in the accompanying drawings, wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations, and modifications canl be resorted to, lwhich come within the scope of the claims hereunto appended.

tive view showing two o f the carrying` levers with their connections.
ReferringA to the drawings byv reference characters the machine comprises a horizontally-extending shaft journaled in the sides of the frame 35, and upon the shaft 35 areloosely mounted collars 35", to which are fixed the toothed accumulating wheels c. Preferabl said Whee s is 40, except for pence columns in sterling machines, when the number of teeth would be 48.
vIn the case of decimal adding machines, it will be found convenient to employ wheels c, each having forty teeth. The collars 35b space the Wheels c suitable distances apart.
The machine casing is formed in the front thereof with a plurality of slots a', through which project the keys a, so as to enable the said keys to be conveniently reached by the operator. At the side of each series of keys and on the front of the machine casing the .digits a2 are provided, these digits being from 1 to 9. Each set of keys a is carried by a quadrant o, which terminates at its lower end in a connecting bar fixed upon one of the collars 35, and the said connecting bar has its lower portion extending-rearwardly and upwardly at an inclination, as at a3, and the connecting bar has its upper portion, as at a4 extending in a vertical manner, and the said upper portion a4.is provided with an off-set a5. The upper portion a* of the connecting bar terminates in a rearwardlyextending Sector shaped arm a, provided with a series of type d for printing the digits l tot). When a set of keys a is in normal position,
v the forward edge of said portion of the connecting bar is in alinement with a Vertical line through the center of the shaft 35 so that the first one of the ty e d will be rearwardly of the hammer tobe reinafter referred to. Pivoted to the off-set a5, as at d2, is avertically-extending ty e carrying arm da., provided at its top' wit a cipher t pe p, and the said arm d3 in that side whic oppose/s the front of the portion a* is formed a notch d to permit ofithe entrance of a shifting lever in the manner as' hereinafter set forth, so as to move the ty e p from normal position, which is below the hammer to be hereinafter referred to. Each of the connecting-bars is adapted to shftably support its .respective quadrant o and sector `arm af upon the shaft 35, and the said connecting bars constrtute the number of teeth on each of' means for connecting the type-carrying sector arm with the key-carrying quadrant, so that when' the key-carrying vquadrant is shifted downwardl the type-ca ing'sector arm will move orwardly, and t e arm da will also have a corresponding movement to the type-carrying sector.
To prevent back movement of each of the quadrants o, each of the connecting bars is provided with a pawl b, ivoted as at b', to the bar and provided wit a nose b2, which is adapted to extend between the pair of teeth of 'that accumulating wheel `c which associates with a quadrant o and its connecting bar, there being a wheel c for each quadrant o. The awls b are constructed in such a manner t at they will travel over the teeth of the wheels c when the quadrants are moved downwardly, the wheels c being held stationary owing to a lockin device engaging between the teeth thereo. The locking device consists of a horizontally-extending bar f, carried at the upper end of a pair'of arms 1, which are ivoted at. their lower end to the shaft 2. he barf is retained in normal engagement between the teeth of the wheels c y means of a spring 3, connected at one end to one of the arms 1, and at the other end to the support 3. The manner in which the bar f is moved from engagement between the teeth ofthe accumulating wheels c will presentl be referred to.
T e top 3b of the machine casing, forwardly thereof, is formed with an opening 3c to permit of the operation of a hammer e to ma e a record upon a'recording strip of paper,14, the said strip unwinding oli the roll 14", passing under and over the guides 14, 14d, and between the friction rollers 41, the strip of paper 14 being positioned by the ouides 14c within the opening 3'3 below the ammer e. Arranged below the strip of pa- -per 14 and retainedv in the opening 3 throu h the medium of the guides 19 is an ink ri bon, which travels between the guides 19b and off of the roller 42.v The ribbon 19 also travels under the guides 19 and upony the roll 43. v
The hammer e is formed with a rearwardlyj' extending arm e', which is fixed to the rock shaft 10. Projecting forwardly fromV the shaft 10 is an arm 9 provided with a pin'S adaptedA to be engage by the upper end of an elevating arm g; 4Extending forwardl from the shaft v10 is a curved arm 1l to whic is pivotally connected, as at 11, a forwardly-projecting lever 12, and a-v rearwardlyrojecting lever 13, the forward or i free en of the lever 12 engaging the ratchet engin teeth 12v, fixed to the upper of the rolls 41, and the rear or free end of the lever 13 en-` the ratchet teeth 13* connected to the ro l 43. The lever 13 has its rear or free end held in normal en a ement with the ratchet teeth 13 throug t e medium of the v ating wheels c.
pulling spring 13b, which is connected at one end to the lever 13 and at its other end to one of the supports 13 for the roller 43 and 14".
To the arm 9 is fixed a rearward extension 18, and to' the upper end of said extension 18 is attached the rear end of a distensible and y contractible spring 17, while the other end of said s ring 17 is fixed to the lug 17 1, car-y ried by lille top 3b of the machine easing.
From the foregoing construction it is evident that when the arm g is elevated, the arrn 9 will also be elevated, owing to the engaging of the arm qlwith the pin 8. During such movement, t e spring 17 will be eX- tended, and when the arm q is moved from engagement with the pin 8 in a manner as hereinafter set forth, the spring 17 will be released, thereby causing the moving ofthe arm 9 to normal position and the hammer to strike a blow, so as to make an impression; or, in other words, the hammer e will strike the paper 14 on to the ink ribbon 19 resting above the ty e or types d, and thus-print the amount. Wien the arm 9 is elevated, rocking the shaft 10, the arm 11 will also be elevated, consequently rocking the levers 12 and 13 and causing the feed of the paper and the ink ribbon. p
rl.`he shifting arm g-is provided with a lug 7 upon its upper end, which is adapted to engage the pm 8, and, below the lug 7, the said arm g is formed with a cam portion 15, adapted to contact with a lug 16 secured to one wall of an opening 16 in the top 3b of the casing. Through the opening 16a the arm g is adapted to operate. The lower end of the arm g is connected to a horizontally-extending lug g3 carried on the lower end of an eX- tension g4 forming a part of a; handle g which is mounted upon one end of the shaft 357 and, between the lower end of the arm q and the end of the extension gf and upon the lug g3 is mounted a roller 20, which travels in the path of an arm r projecting upwardly from one -of the arms 1.
From the foregoing construction it is evident that when the handle g is lowered, the arm g will be elevated and the roller 2() will lenga e the arm 1 and shift the arms 1 rearward y, which will car the barf therewith, so thatthe said barfwi l be moved out of enagement between the teeth of the accumu- When the arm q is elevated through the medium of a handle g in the manner as stated, the lug 7 will engagekthe pin 8 and rock the shaft 10 owing to the fact that the lug 7 will elevate the arm 9. During the upward movement of the'arm g the cam portlon 15 will enga e the lug 16, and the said arm g will lbe slnfted forwardly, so that the lug 7 on said arm g will be moved out of engagement with the pin 8, thereby releasing the hammer, so a record can be made upon the pa er strip. `f Y The handle g 1s urthermore provided with an extension g carrying a stud 37 which has the forward end of a longitudinally-movable nected thereto, as at h', a lever t, which has 'rear end of the everi has a carried by the machine rovided with a rod 4. The vertical lever j and the lower end its. forward end connected thereto, as at j',
. of said lever is substantially hookedl shaped,
as at j?. Said end jz'is adapted to engage a rod or bar 5 carried on the forward end of a lever-k which. ispivoted u on the su port k rame. W en thehandle g- 1s lowered, the extension g will be carried forwardly, which in turn, will carry the bar gfs forwardly, and allow the upper end of the arm h to, also move forwardly,lwhich in turn will permit the levertl and the rod 4 connected thereto to fall. The lowering of the forward' end of the levert' will elevate the lever 7'., so that the hooked end oi said lever j will engage the ba-r or rod 5 and lift the forward end of the lever k, The latter carries as indle k2, which extends at right angles am said lever k also carries a vertically extendingl arm k3 having an singularly-extending spindle c adapted to engage the rear end of a trip lever 25, to be hereinafter referred to. A spring connection r isarranged between the arm 7c3' and the sup )ort k. A sprir yconnection k is provided )etween the lever and the bottom of the machine. The spring connections ks and k are adapted to return the elements l: and k3 tol normal position. A s ring connection mis provided between the ar 9'2 and the protuberan ce m2 on the lug g3. This Vspring connection insures the rear endof the. bar g2 resting upon the su port g". A spring connection 3U is providbd between tie protuberance m2 and a support 3n for moving the handle g to its norma]l position, which also insures the moving of the parts connected to said handle g to. their normalv osition. A spring connection 1nl is provide( between the pivot h and the arm q for retaining' the arm g in contact with the pin 8 and lug 16 when. occasion requires. A spring connection 'm is provided 'f or retaining the lever j in contact with the bar or rod 5 henoccasion so requires, and a spring connection: m5 is provided between a depending arr-n. 40 carried by the lever l and a shaft m6 to insure the lowering of the lever i.
Connected to the lug` 3.7 is a rearwardlyextending rod 6, whichis articulated, as at 6 a, to a lever l., the latter being pivoted at l', and which has av cam end 38 te. engage a stud l? carried by a lever m. One end of the lever ym is pivoted, as at 13, and the other end' is bifurcated, as at l, and the said bifurcated end P straddles alug l carried' byon einem ber of an L-shaped arm n. The arm 'nslides along the.notches. d in the arms d3 for the purpose of pushing the arms d with the4 cipher types p from under the hammer e W en necessary. The arm 'n travels in a straight line engaging notch by notch in the arms d3 until it comes to a. connecting bar which has been actuated. Such actuated connecting bar will then stop or` arrest the travel of the arm n. A slidingbearingl l adapted to travel upon the bar Z7 is provided for the arm n.
Pivotally connected to cach of the portions a4 of the connecting bars is an L-shaped lever 31 having a stud 31 a, and the said lever 31 is pivotally connected, as at'3lb. The lower end of each of the levers 31. is connected to a rearwardly-extending bar 31, the latter having its rear end attached toa dis tensible and contractible spring 21, said spring being connected by a hook 21 a to a rod- 21b carried by a lever o. The function ol the springs 21 is to return the key quadrants and type sectors to normal posit-ion. The return movement of the quadrants, (such movement being had owing to the action of the springs 21) is limited through the medium of a stop arm s having a protuberance s', which is adapted to be positioned in the path of a lug 22 carried each oi' the connecting bars.
yThe rear end of each of the arms s has a spring connection between the same and the s aft m6, said spring connection being indicated by the reference character 29.
The action of the wheels c and the quadrants will go on with each item that is printed until the number of teeth on any of the wheels c passes 9. This it will benecessary for the column or columns in which"9 has been exceeded to carry in the next column to the leftas follows from the ordinary rules of addition. This is accomplished by the -following assemblage ot parts:
Fixed to each of the accumulating wheels c is a carrying am t provided with protuberances 23 in the form of beveled teeth, which are adapted to engage the up er arm of 'a lever u, there being, a lever u or each cam t. These levers 'u are in the form of b ell cranks with the exception of the lever "u in the extreme left column, such lever u being a one-arm lever. Each of the levers u is pivoted upon a su porting baru. The other arm of each ci) the levers u, which is not engaged by one of the protuberances 23, is connected as at u, to a trip, lever 25, which is adaptedv to engage and shift a lever arm 2-7\ from under a stop rod 28. A spring connection ua is arranged between the trip lever 25 and its respective lever u. There is a lever 25 and a lever arm 27 for each of the wheels c with the exception of the right-hand wheel. The quadrant stopped bly a contact plate as this quadrant does not require tomove an extra tooth for Working with this wheel is the purpose of carrying, there being no quadrant to the right of it, it being noted that the levers and 27 in any particular column are actuated by the wheel in the column immediately to the right of it. The lever 25 is provided with a shoulder 24 and the lever -arni 27 with a pin 26. Y
The shoulder 24 is adapted to -be shifted to one side of' and engage the pin 26 so that when the bell crank lever u returns to normal position after being depressed the lever 25 will pull the lever arin 27 from under the rod 28. The lever arm 27 depends from and is suitably connect-ed to the stop arm s, as at 27"l and a spring connection 27b is arranged between the lever arm 27 and its respective stop arm 5.
From theforegoing it follows that when the Wheels c are at' Zero 7.the back of any one of the protuberances 23 on the Carrying camt is just in front of the u er arm of a bell FP i crank lever u and as the W eels c move around t-be cams t move with them, one of the protuberances in due course then pressing down the lever u.. The lug 24 on the trip lever`25 then passes to the other side of the pin 26 on the lever 27 belonging to the next quadrant to the left. Directly the wheel has passed beyond nine teeth from zero the lever u rises up behind the protuberances 23 of the cam t and the trip lever 25 pulls the arm 27 from under the iod 2S. The right-hand ends of the levers s rise under the action of the springs 29. The next quadra-nt o to the left rises up by the action of the spring 21 a distance of one tooth, taking its corresponding Wheel with it. v l
When the operator releases the lever g the spring 30, in a state of tension, brings this lever and other parts in connection therewith back to their normal position and any quadrants o that may have been advanced an extra tooth by reason of having' carried over,'are l'e'turned to normal by the rod 4. 'lhe levers s are })ressed"'(lo\\'n by the rod 5 and the lever 27 then passes to its normal position under 28.
To prevent the pawls b fronrbeing jerked from their position in the teeth of the wheels c the quadrants o suddenly come to a stop, a bar or rod :v is provided iitted on its upp part with another bar or rod at, and connected by connections 39, .40 to the shaft 'n which is tittedthe lever z. vYVhen the handle orlever g' is actuated the rod x moves and the other rod x assumes a'horizontal position preventing the pawls b from moving from normal position.
A quadrant y is fixed tothe lever g an'd is provided with notches y into which a spring actuated pawl z engages, preventing he lever g from returning to its normal position untilv the full stroke has been.performed. Spring are fitted tov the various levers to ein in their normal position.
'complementary parts, these parts Although for the sake of illustration I have only shown four quadrants and foursets of will be multiplied according tothe number of columnsof figures .required to be dealt with.
The total is obtained by pulling the lever, fu forward as far as it will go and then returning it. This action relieves the tension on springs 21, allows the d etent 31 to drop into the notch directly under it, thus locking the accumulating wheels c to their quadrants o and pulls on thepitinan 32, thus disengagiing the rod from the wheels c, the quadrants o then drop down, taking the wheels cwith them; one point 23 on each carrying cam t comes intocontact with the lever u. The rod f then returns, relooking the wheels c and quadrants o in position to which they have dropped the figures falling in line under the hammer e constituting the total. By this means the total is practically converted into a iirst item placed in the niachine ater it has been cleared and before the handle g has been pulledand 'it may be either printed and carried forward, printed and cleared from machine orl cleared from machine without printing.
To print total and carry it-forward itis'necessary to pull the handle g as usual for an item.. The total willy then be rinted and still left in the machine to be added to any subsequent items.
To clear machine the total lever-w is then pressed down as far as it will go. The' arms 33 and rod 34 with the lever ware fixed to the.
the clearing lever w as described above. This returns keys without disturbing amount already iii machine.
The rod 6 is connected to a stud 37 o n the. leverg. v.fhen the handle or lever g 1s de pressed-the rod 6 is pulled actuating the cam 38 on the lever l. This' allows thev slotted arm m and with it the L-shaped arm .n to' shift'toward the right-hand side of the -top late. 'l he arm n slides between the cipher evers d', and the quadrants-o pushing'the, cipher levers d toward front of t e plate and from underneath the hammer e.
As shown in the drawings theV quadrants o before the handle g is pulled by depressing" are normal and therefore, if handle g were y pulled all the cipl'iei's d Would be shifted and I nothing Whatever printed.
If'any quadrant o Were p ulled forward asiin setting up an itemwhen the handle ,is
pulled the leverI a would travel, shifting all the ci )hers d to the left of that quadrant o pulle forward, and beingprevented by impinging on the side of said quadrant fromv type quadrants.
