Be it known that I, Haaay WAL'ma Jones,

a citizen of the United States, residing in thecity and county of San Francisco .and 5 State of-California, have invented certain new anduseful Im rovementsin'Com uting-Machines, of w ich the following is a specification.

The present invention relates to calcu-.

ting machines'generall but more particuly to a t pe of machine by theemplo eat of wiiich one is enabled to nick y nd accurately multiply figures, not y the long and tedious method emgloyedun ma- I5 chines now in use, that i y adding the multiplicand the number times required,

by the multiplier, but by multiplying the multiplicand successively b the units, tens and hundreds of the multip ier and after the last operation, obtaining the total result without any further operation of the machine. I

The invention has for its principal objects, to provide a multiplying machine which is capable of being operated to multiply any given s" a and after the answer thereof has been ob .ied, is capable of operation to wave the answer;-'to provide a structure luring separate multiphcand and multiplier operating mechanisms; one in which the multiplier key is automatically restored to its normal vosition on the multiplication of e multiphcand by the operated multiplier, 1 one employing a novel form-of computmeaus which when once set to 'correond to the multiplicand may be multiplied by any number in the multiplier without the necessity of being reset.

With theabove mentioned and other objects in view, the invention consists in the novel construction and combination of parts l g-einafter described, illustrated in the ac-' companying drawings and ointed out in the claims ieieto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without de artin from the spirit or sacrificing any 0 the a vantages of the invention.

The member St'Fig. 18 is rovidcd with peripheral flanges 87 each ormed with an oppositel disposed ratchet surface 88 and 89 wine are engaged respectively by the pivoted pawls 90 and 91 carried by the arms 92-and 93 pivotally mounted t crank arms 94 and 95, mounted on the shafts 96 and 97 between collars 98, and said shafts extend through the side members of the frame and are connected at their ends by the plates 99 and 100. The shafts 96 and 97 and plates 99 and 100 are capable of slight transverse movement relative to the supporting frame members and 6, to position the pawls 90 and 91 into operative engagement with their respective ratchets, to move the carria e one step either in a forward or reverse irection on each operation of the lever 71.

Positioned between the supporting frame member 6 and the plate 100 and surrounding the shafts 90 and 97 are coiled springs 101 which exert pressure on the end plate 100 and retain the shafts 96 and 97 in their limit of movement to the left, thus positioning the pawl 90'into operative relation relative to t 91 from its rack 89 to perm: the indicator wheel carriage to be advance to the right. It is necessary in changingthe operation of movement of the indicating wheel carrings from right to left or vice-versa to advance the carria one step. in the direction of the desire movement,-and this is accomplished in the reversin of the carrings in its movement from t to right by the following mechanism. The above shifting of the carriage is necessary in order to ition the proper indicator wheels 111 men with the pro r gear wheels on the initial operation 0 the lever 71, as after the last complete operation of the lever 71 in any multiplication or the provin at position by a coiled spring 106. The oppoe rack 88 and disengaging the pawl thereof, the indicator wheels are in mes hub said fin r plunger is retained in its outermost I site end of the crank arm is ivotally mounted to one end of a rod 107 s idably mount d in guides 108, formed on an arm 109, pivo ed at one end to a lug 110 projecting iron the side frame member 6. Pivotally mounted on the outer end of the arm 109 is a pawl 111 which is alsopivotally connected', as at 112, to the outer end of the rod 107, and said pawl is formed with a beveled face 113 which is adapted to engage, when the finger plunger is pushed inwardly, certain of the ratchet teeth 114 formed on the shaft. 80, moving the carriage one step to the right, and during this operation the end plate 100 is forced inwardly moving the frame to the,

right, disengaging the pawl 90 from its associated ratchets, and moving the pawl 91 into engagement relation with its associated ratchets. The frame is retained in its position of movement to the right by a catch 115 pivoted tea lug 116 on the frame 6 and said catch is normally forced downwardly to engage over the end member 100 by a spring 117 which compresses against an arm 118 formed above the catch 115.

The inner end of a trip arm 119 pivoted to a lug 120 carried by the .frame member 6 is normally forced outwardly and into contact with the arm 118 by a spring 121, (Fig. 8) and the .outer end of said trip arm is adapted to be engaged by lug 122 carried by the shaft 80, on the motement of the indicator wheel carriage a given distance from right to left, the lug ofperating the trip arm to release the catch mm the end plate 10.0 and permit the fr me to be forced to the left hv the spring 01, disengaging the pawl 91 from its associated ratchet and positioning the pawl 90 into operative relation relative to its ratchet.

Pivoted to the lower portions of the crank arms 94 and 95 is a rod 123 Fig. 13 which operates through 'a guide 121 and is providcd on its lower end with anidler' 126 which rests on an operating slidc127 formed with a raised portion 127, and, which is mounted in a guide 128, and sup orted on a roller 129. and said operating side is pivotall connected at one end to an arm 180 have to the shaft 70.

From the above construction it will be apparent that on each operation of the shaft to in a forward direction the crank arms 94 and 95 will be operated, and will in turn actuate the pawls associated therewith, which, in accordance with the one engaged with its rack will cause the indicator wheel carriage to move one step in the direction of its travel.

Loosely mounted on the o posite ends of the shaft are arms 131 ormed in their ortions with a suitable out out 132 in whic o eratethe pins 133 Fig. 10 carried by the sliaft, this construction roviding a' rotation of the shaft part way in either d1- otally connecte rection before the pins strike the sides of the cut outs, to 0 erate the arms.

The up er en s of the arms 131 Fig. 10 are pivota ly connected by links 134 to levers 135, and other links 136 the levers 135 being connected to a ffiaft 137, and the links pivto the ends of a plun er controlling bar 138, which slides in suits le guide slots 135 in the'side frame members 5 and 6. The 138 is provide verse openings 139 which register with similar.openings.1 30 in astationary mounted guide bar 141. positioned between the side members 5 and 6 and directly in rear of the controlling disks 8 and 9.

Slidabl mounted in the openings 139 and 140 are he plunger rods 1 2, Figs. 11, 13 and 14, each adapted to coiiperate at-one end with a units or tens disk, and each of the plun ers, coiiperatin with the units, and tens isks are forme on their-opposite-ends with racks 142, which enga e respectively the upper and lower faces of t e pinions 143 rotatably mounted on the shaft 144 and each mounting a toothed gear whee 145 which are connected to the shaft by the springs 146 coiled in opposite directions so rat on the forward movement of the plunger controlling bar the springs 146 will cause their respective units and tens wheels to rotate in the direction of the arrows Fig. 13, forcing the plungers into their proper stepped recesses in the peripheral ed e of the units and tens disks.

he gear wheels 145 are positioned to alternately enga e the toothed eripheral edges 147 of the indicator w eels 148, mounted to rotate on a sup orting shaft 149 carried by the indicator w eel .carria e, and the operation-of said gear wheels on t e plungers being seated in their pro r receases in the controlling disks an Withdrawn therefrom, will cause the indicator wheels to rotate and display the result of the multiplied sum through the openings 4.

Iaterposcd between the plunger controlling bar 138 and the ends of the racks 142 are coiled springs 149 Figs. 11, 18 and '14 which on the return of the plunger controlling rod to its normal position, as in F1 13, will force the rear ends of the racks 14 against the free ends of dogs 150 and 150', formcd'at their front ends with step recesaes 151, and pivoted to the shafts 52 adjacent which pivot points the dogs associated with the racks connected to the plungers of each pair of units and tens d sks are normally maintained in contact with the transversely extending bar 153 by a spring 154. The rear end of each dog carries a spring..155 which engage in the notches 156 formed in a plate 157, slidably mounted m uides 158 in the side members 5 and 6 and plunger controlling slide bar :nent actuates with a plurality of'trans- Projecting laterally .ot the edge o ''the dog 150' and'on the complete ward position by coiled springs 159, one mounted in each guide. The means for restoriu the pawls to their normal position after ing operated, in a hereinafter described manner, consists of a trip lever 160, Fig. 13, keyed to the shaft 137 and provided at its end with a tip'161 keyed as at 162 and yieldably connected to the lever 160 by a spring 163, and said tip on its upward movea curvedarm 164 ivoted to a shaft 165, and connected by a. 11nk 166 to a lever 167, mounted on one of the shafts 152 and said lever is in turn connected b a link 168 to the sliding plate 157. It wil be apparent that the movement of the trip lever in one direction will vcause the tip 161 thereof to contact with the curved arm 164 and pass under the same, but on the movement of the trip lever in the opposite direction, the tip 16 therepf will not be permitted to swing when assing under the curved arm 164, but wi l. -enga e the same, which through its a l the springs 154 to draw the pawls to their normal position.

from the indicator wheels 148 are pins 168, each adapted on a complete rotation of one of the wheels to contact with one end of a trip .finger 169 (Figs. 12-18 and 14) positioned immediately in rear thereof and pivoted to the shaft 81 of th the carriage in either direction the fingers pass in coiiperative relation between suitable upper and lower trip levers 170 and 171 Fig. 16 which are tively pivoted to the shafts 172 and 17 and carry the pivoted hangers 174-and 175 which are respectively connected by the members 176 and 147, from which de 178 and 179. The one end of a lever 180 pivoted to the late 158 and contacts with the upper edge 0 the dog 150, and on the com lete rotation of one of the wheels 148 when t ecarriage isiraveliag to the right is operated to press-the do at that time associated with that whee downwardly, which will permit the rack 142' associated with a tens disk plunger, in its retum movement, to be pushed rearwardly bv the sprin 149' into the first recess151-t ereof, whic permits the indicator wheel to be rotated one numeral beyond that which would ordinarily take place. The link 179 and its associated parts is employed when the device-is used for the proving of the multiplied sum, and the carriage isppernd the respective links .ated from right to left and said lmk is connected with a'lever 181 pivoted to the rear l'ate 1'53 and contacts with the lower rotation of one of thei wheels148 in reverse direction. will operate the dog associated therewith upwardly'and permit the rack'142 iate links andlevers wil move the plate,157 rearwardly and permit e carriage, and on the movement of ink 1 78 is connected to associated with a units-disk in its return movement to be forced by the spring 1-19 into the first recess 151 of the dog 150' which causes the indicator wheel to be rotated one numeral beyond that which would ordinarily take place.

After prov -ng a multiplied sum, in a manof the carriage, and pivoted to a lug 188.

)rojecting outwardly from the frame memer 5. The lug is normally forced outwardly by a coiled compression spring 18%, and is forced in contact with the end plate 79 by pressure exerted on a slidably mounted plunger 185. which'is pivotally connected to the finger and extends exteriorly of the casing 1.

On each forward movement of the lever 71 an arm 186 secured to the opposite end of the shaft therefrom, strikes a spring pressed pivoted dog 187 (Fig. 3) which is connected by a link 188 to a pivoted crank arm 189. which is normally in contact wit"- the head of the stud '26, operates the san: ahich causes the restoring plate 21 to slide to the right, which movement restores all of tin actuated keys to their normal position.

The restoring of the keys to theinnormal tors of the multiplicand disks as the same are retained in locked en agement on the shaft 7, but permits the nniitiplier arm (37 to be moved to engaged relation with a newly operated button on the next rearward movement of the lever 71.

Should it ever become necessarv to manually reset the indicator wheels, the u'riage is capable of pivotal movement upwardly on the shaft 76, which disconnects the indicator wheels from the gears 1-15, the carriage being maintained in its raised position by the pivoted catch 100 Fig. 12 formed wit! the recess 101 therein, and'which is forced rcarwardly into engagement with the shaft 77 by the coiled spring 192.

The parts being assembled as in the drawings, the device is operated in the following manner z-Jf it be desired to multiply 9i) by 8, the multiplicand is first set up by operating the multiplicand buttons'w and 1 represeating 99. he lever '28 is now pu led forwardly which permits the springs 14 to force the sectors of the'lirst two pairs cl.

units and tens disks to rotate the same the proper distance about the shaft 7, the arms 16 of the sectors limiting the m'ovemcnt thereof by striking the lower ends of the operated multiplicand buttons is and 3 (Figs.

2, 3 and 4). Further movement of the lever 28 forces the collar -11 inwardly on the shaft 7, raises the locking member 86 into the slots 35, and locks the shaft. 7 and units and tens disks 8 and 9 to rotate in unison (Fig. 8). The multiplier button 2 representing 8 is now operated and the lever 71 is pulled forwardly, which first operates the mechanism to advance the carriage one step to the right, to position the gears of the indicating wheels in mesh with the gears 115 associated with the units disk's Fig. 13. Simultaneously with the above movements, the finger 7-2. in its travel over the rack is released from the pin 73 and permits the spring (39 to rotate the shaft 7 with the controlling disks keyed thereto until the arm tiTassociated' therewith contacts with the depressed multiplier key 2 (Figs. 7 and S), at approximately this same time the arm 186 has been forced to a position in front of the spring pressed pawl 187, and the pin 133 on the shaft 70 has completed its movement through the slot or cut out 132'in the arm 131, and is forcing the arm forwardly, which operates the plunger frame 138 to permit the springs 146 to rotate the gears 143 to force the plungers 142 into the stepped recesses of the controlling disks positioned at the end of the same, and in .this movement the units and tens plungcrs associated'with the respecti e operated multiplicand keys will rest 11. the respective etc )5 B andC of the sectors A of the units ant tens disks of the first two pairs of disks i to the right. It will be observed by referposition does not in any way etl'cct the secence to Fig. 15 that the first step movement of the carriage has inter-meshed the indicator wheels with the cars associated with tho units plun ers and that the movement of the units p angers into their respective seats in their respective controlling disks will rotate the indicator wheels to such po- .sition as to present the figures 22 thereon upwardly in line with the sight openings 4. During this previously mentioned operation, the plunger-s associated with the tens controlling disks in their movement to their seats have rotated the gears 14:) associated therewith, but said gears not bring in mesh with the indicator wheels do not rotate the same. As the plunger controlling frame is being moved forwardly, theshaft 137 is also being operated, which diaws the trip arm 160 forwardly, which through its respective connections forces the plate 157 rcarwardly, which )ermits the springs 15%- to draw the pawls i530 and 150' inwardly as in Fig. 14, which prevents the springs 1 h) on the .rear ward movement of the plunger controlling slide 138 from forcing the racks H2 rearwardly-into one of the steps 151, until such time as it is necessary to carry a tens nameral from one indicator wheel to another 7 the carriage advancing mechanism is first 4 operated and the carriage is a vanced an other step to the right, which. disconnects theindicator wheels from the gears associated with the units plungers and intermeshes the same with the gears associated with the tens lungers, butthe indicator wheel to the rig t havin been intermeshed with the first units disk uring the previous movements will be disengaged therefrom and permitted to remain idle, as the units of the result 2 has been recorded thereon and is displayed beneath one of the openings 4. Further movement of the lever 71 rearwardly forces the slide 138 rearwardly which removes the plungers from their seats, and forces the racks associated with the operated multiplicandbuttons rearwardly. The indicator wheels now being in gear with the gears associated with the tens plungers will be rotated on the return movement thereof a distance equal to the seven 'steps in the tens controlling disks, and will thus display through the openings 4 the res ective numerals 9 tens and 7 hundreds, as the tens wheel had recorded thereon two steps-from its (previous engagement with the gear associate with the second un1ts disk, and the hundreds wheel had previously been in engagement with a gear associated W lth a plan er which had rested on the segment 11 0 the third units disk, thus the resultant sum of 99 multiplied by 8 which equals 792 is displayed through the openin 4. In the operation of the machine the lake associated with the non-operated multiphcand keys will present to the plungers on the actuation of the multiplierlever their segments A", which will prevent the lungers from moving any steps in e ther. irection. While the rotation of the indicator'wheels 18 taking place the flexible end of the trip bar 160 is passing-over itsassociate'd crank arm 164 without operating the same. Simultaneously with the reviously mentioned opera tion, the arm 86 in its return 'movement actuates the trip 187 which, through its connections operates th causing the beveled lugs 28 to contact with the shoulders and restore the depressed multiplicand and multiplier buttons to their normal osition. The restpringof the multiplican buttons will not in ani the positionof-the arms 16 set now held in locked pol'tion on the shaft 7,

a and will remain in such position until the lever 28 is'-thrown toits'normal inoperative positidn. aka the lever" T1-;has--about complcted its retum movement, the 'arm 72 strikes the pin 78 and forces the arm rearwardly, which, through suitable connections position-Fig 1. The. lever 28 is now 1,14o,es4

71 is moved rearwardly and in its movemente restoring plate 21 way efiect operated in their inverse order. edlsks are ing of anysuccessivelv moved rearwardly which unlocks the disks 8 and 9 from the shaft 7, and operates the bar 34 to move the. segments 11 against the action of the springs 14 and cause the same to assume their full line position, as in Flg 4.

o prove the answer and clear the indicator wheels, the carriage reversing mechanism (Figs. 17 and 19) is thrown into 0 eration, which changes the movement 0 the carriage from left to right to right to left on the movement of the lever' 71, and one complete operation of this lever will rotate the indicator wheels in a reverse movement to that which .was employed when the answer was being obtained.

In Figs. 20, 21 and 22 there is disclosed the dia rammatio multiplication of a diflicnlt pro lem, the forward movement of the carriage and the numbers displayed b the indicator wheels during each forwar and backward movement ofthe multiplier lever in obtaining the answer, and the rearward movement of the carriage and the numbers displayed by the indicator wheels durin eac forward and rearward movementflog the multiplier lever in proving the answer. By reference to these figures, it will be apparent thateach button ofithe multi lier set representing the respective multip ier numerals I8 epressed in a direction from right to left, one at a time and after each depressed, the multiplier lever is one is moved forwardly which rotates the indicator wheels to have recorded thereon the units of the result, then the lever is moved rearwardly which movement adds to the button andthe movementof the multiplier lever in both directions, the sum of the multiplicatipn, andthis takes (place until the final result has been obtaine .In proving a multiplied su'm,,the same operations are performed as when obtaining tie answer, but the multiplier buttons are 123 It will be apparent that ,I have constructed a machine that is adapted for the multiplyiven. numbers and one w ich iscloses each multiplied sum of the multiplicand by the depressed multiplier 126 button, together. with the result previously recorded on theindicator wheels'; one ,b which the answer of the multiplied sum is capableof being proved, and one whiohiis simple iii construction, maybe constructed 1 00 I ters Patent is at little cost and is well adapted'for the purposes described.
