   GENERAL DESCRIPTION
The invention is aimed at a new differential mechanism intended for calculating machines, cash registers and other similar office machines. Each order of designation of the machine corresponds to one of these differential mechanisms and each of these comprises a primary organ and a secondary organ connected by a part which. in

    cooperation with the mechanism actuating the differential, sets up the primary and secondary components according to the value. the amount key pressed.



   Each primary differential member is provided with a toothed segment-shaped portion engaged with the teeth of a pinion attached to the inner end of a corresponding auxiliary differential shaft.

   This shaft is perpendicular to the main differential shaft which supports, in rotation ... the primary and secondary differential orgeares The auxiliary differential shaft extends horizontally over the entire length of the corresponding row of uprights and is placed directly below of the lower ends of the touching rods *.,

       The auxiliary differential shaft is provided with a locking disc for each upright touch and these discs are spaced apart so that they are in alignment.

 <Desc / Clms Page number 5>

 with the corresponding keys.



   In the application given here by way of example, each row comprises ten number keys including a zero key which takes the. instead of the usual zero-stop mechanism which can,

   if desired to be incorporated into the present machine in an appropriate form
By lowering a numbered rising key, the lower end of its rod is moved which comes to be placed in the path of a stopper on the corresponding stop disc. These slats are arranged in progression to par.- set a 1- auxiliary differential shaft to increase 1! rotation angle, depending on the value of the key pressed.

   Far example, the zero key, opposes any movement of the auxiliary differential shaft and of the primary differential member; the number key "l" allows the movement of one step of the shaft and the primary organ the number key "2" allows the movement of two steps, and so on
The differential mechanism according to the invention differs from ordinary differentials in that instead of the usual ten stops or steps of movement, it is set with twelve steps so as to correspond,

   the case falling to the English monetary system.



     The auxiliary differential shaft supports., In each order of denomination of the present machine, a certain number of drive control gears the corresponding wheels of the totalizers with which the machine is equipped, In the present application, twenty of these control gears to drive the corresponding wheels of the twenty totalizers which equip the machine. However, the number of totalizers is first and foremost a question.

 <Desc / Clms Page number 6>

 do choice:

  , because the new arrangement of the part of the differential mechanism which controls the totalizer, makes it very simple to increase the totalizing capacity of the machine without great difficulty and without appreciably increasing the bulkiness. mentioned above, the present thing is provided with twenty totalizers each comprising a totalizing street for each order of denomination and, it, it is desired,

   wheels., these additional My rouse of each totalizer are mounted on a plate which forms a complete group of said totalizer, which can be easily installed in the machine, or be removed from it, without disturbing the other totalizers in any way. can use any type of carry mechanism for both addition and subtraction totalisers.

   Each ticker wheel is provided with a transfer rocker which also serves, in cooperation with the corresponding zero stop pawl, to stop the wheels of the corresponding totalizer at the zero position in the or, 4- rations of total and subtotal ;.



   A segment connected to the secondary differential organ is used for setting the position of the printing press and indicators This segment is in turn connected by transmission engramages to the printing wheels and to the corresponding indicators In the first phase of machine operation ,.



    .The.'! secondary differential members and the zon- on Mont mechanism brought back to the initial position by a single return mechanism. In this case this initial position is the opaièe of the differential mechanism, after which the differential control mechanism comes into contact with the rods ,

   

 <Desc / Clms Page number 7>

 connecting the primary and secondary organces of each order to ensure differential movement. Since the secondary organs are connected to the printing and indicating mechanisms and therefore carry a higher load and offer greater resistance than the primary organs the secondary organs remain stationary while the links move the links. primary and differential shafts

    corresponding auxiliaries.



     The initial movement of the primary components and the auxiliary shafts continues until the stop teeth on the corresponding discs make contact with the lower ends of the lowered buttons 3, which positions the auxiliary shafts and the differential components. primary,

    according to the values of the composite uprights on the keypad The end of the initial movement of the auxiliary shafts and of the primary differential components has the effect, under the influence of the differential control mechanism, of causing the secono- daires as well as the corresponding wheels and indicators, depending on the position of the auxiliary shafts and the pir- mayary components. Once these positions have acquired their position,

     an alignment mechanism engages the teeth of the secondary differential members to align and hold these parts during operation of the printing mechanism.,
The differential control mechanism, in addition to activating the differentials via their connecting rods,

   also causes a different return rod to oscillate ... The return rod is extended by concentric return slots provided in the primary differential members and during its initial movement it

 <Desc / Clms Page number 8>

 moves with the primary organs to take a step]. tion corresponding to the key down. The slots provided for the return rod are long enough to allow complete displacement of this rod,

     without interfering in any way with the proper placement of the primary organs
In the present application, a spring is placed between the return rod and each of the primary differential members, so that the initial movement of the return rod elastically drives the primary members;

  , until this movement is interrupted by the lowered key, These springs are often referred to as "conductor springs" and have only been added to this differential mechanism as an additional safety precaution,

     If desired, they can be removed without affecting the operation and the perfect efficiency of the differential mechanism.



   The return movement of the return rod allows it to pick up the primary differential members and bring them and the corresponding auxiliary shafts back to their rest or zero positions The secondary organs, printing segments and wheels and corresponding indicators, on the other hand, remain in their acquired position at the end of the operation of the machine ,,
In subtraction operations.

   the wheels of the selected totalizer (s) come into engagement with the corresponding control gears carried by the differential shafts, before the latter start their initial movement This movement;

       turns said wheels in a direction corresponding to the subtraction to subtract therefrom the value of the lying down keys. A fis

   For Addition operations, the wheels of the selected totalizers engage with the corresponding control links, after being placed in position by the keys lowered and before the return movement of the gears begins. -This return movement turns the iron wheels in a direction corresponding to the additon, to add the value of the amount composed;

For totaling operations, the wheels of the selected totalizer engage with the corresponding control gears before initial movement of the auxiliary shafts begins.

   This movement, since no key is lowered, turns the wheels in a direction corresponding to the subtraction until they are stopped at the zero position by the teeth of their transfer rocker arms which come into contact with. the corresponding zero stop pawls This has the effect of positioning the auxiliary differential shafts and the corresponding primary differential members according to the value of the total accumulated on the wheels of the said totalizer.,

     In turn, the primary organs position the corresponding secondary organs, the printing wheels and the corresponding indicators according to the value of the accumulated total.
While the selected totalizer wheels are at zero and before the return movement of the primary differential members and auxiliary shafts begins.

Simultaneously, the roller 154 is moved away from the ridge 155 of the rod 77 without disturbing the positioning of the secondary differential member 80 and of the segment 82.

   In this way, these parts, the character wheels and the corresponding indicators-remain in the position acquired at the end of the operation of the machine.



   According to fig. 6, it can be seen that when the primary differential member 66 is in the zero position and the secondary differential member is in the initial position shown here, a protrusion of the secondary pane 80 is in contact with a square 158 of the primary organ 66. Likewise, according to FIG.

   8, when the primary differential member is put in position under the effect of the lowering of the mortant key, and the secondary member following that of the primary member, the edge 134 comes into contact;

       with a square 159 of the primary organ. A positive connection is thus produced to stop the primary and secondary members in their 'extreme position .. in both directions of movement.



   It has been seen that in the operations of subtraction the wheels 68 (Figs. 1 and 2) of the selected totalizers are engaged with the corresponding control gears 54 before the initial movement of the gears, shaft 52 and shaft begins. primary differential member 66, which movement rotates said wheels in one direction

The secondary organ then positions the primary organ 66 to repeat and record the amount of the previous operation, either positively or negatively in the selected totalizer (s),
Fixed on the repeater shaft 131 (Fig. 16).

   There is an arm 176 connected by a connecting rod 177 to an elbow lever 178 pivoting at 180. A branch of the lever 178 carries a stud. 181 which connects it to the stem of a repeat key 192. This has, at its upper end, a head which emerges from the keyboard 37 (Fig. 1) and the lower end of its stem is guided by a support 183 fixed on the frame of the keyboard.

   The arm 166, thanks to the slot and the pin 164, moves the connecting rod 164 upwards, to disengage the lug 167 from the notch 168 of the lever 169 and simultaneously engage 1! lug 165 in a notch 185 threatened in a fixed support 186, Therefore, during the operation of the machine, the lever 169 (Fig.

     16} moves empty ... backwards and forwards, without acting on the aligner 161 and thanks to the notch 185, it locks aligeu in the teeth of the differential member 80, to ensure that it remains in the positions in which the previous operation had been placed
The movement, in the senastiroreum direction, of the arm 130 (Fig.

   19) after lowering the repeat button 182, has the effect of lifting the lug 123 and slipping it out of the notch of the lever * 124, after which the lever tilts empty during the operation of the machine, without driving the secondary differential organ, neither the sector 121, the oath 120, the pinion 19, nor the shaft 96,

   in the manner already explained with regard to the additio and subtraction operators.



   It is evident from the foregoing that totals transfer operations can be performed

 <Desc / Clms Page number 38>

 simply by depressing repeat key 182 to repeat the amount of a previous subtotal or total operation and that total amount can be simultaneously registered in any number of totalizers.



   The movement, in the reverse direction, of the crank 176 (Fig. 16) after the lowering of the repeat key 182, brings a tooth 187 into engagement with a corresponding tooth 188 provided on the latch 189 of the repeat key, latch mounts on shaft 132 and is biased by a spring 190 which normally maintains the latch in resilient contact with a fixed stop 191.
