Gen and description No. mas-e1.

scribed in the parent application, Serial Number 299,112.

Described in general terms, the mechanism consists of a differentially movable actuator, particularly adapted to be controlled by banks of keys such as illustrated.

This differential mechanism may be used to operate totalizers for the purpose of selecting them, adding upon them and also for resetting them to zero, as desired.

Associated with each dilferential actuator is another diherentially movable member adapted to be controlled by the actuator through a lever or, what is known in this art as a beam, connection.

Indicators to indicate the keys depressed, and printers to designate the keys depressed, are shown in connection with the differential actuator. These indicators and printers are set to the proper position by the above re ferred to beam device under the control of the differential actuators and the keys.

Operating mechanism This mechanism may be operated either by hand or by a motor.

The motor mechanism which it is desired to use in connection with the present invention is of a well known type, and is described in Letters Patent of the United States No. 1114,418, ranted to Charles F.Kettering and Wilham A. Chryst on June 29, 1915. For a detailed description of the same, reference may be had to this patent. The only part of the motor mechanism necessary to illustrate in this case is shown in Fig. 1.

A worm gear 30, which forms part of a motor clutch device, is loosely mounted on a stud 31, carried by the machine side frame. This worm gear is rotated by a worm 32 on the armature shaf of the motor (not shown). The motor clutch has three locking discs, only one of which, 33, is shown. Each disc has a stop plate 34 enszaqed by the nose of a locking lever 35 pivoted on the machine side frame.

The locking disc 33 performs certain functions in connection with the release and oper tion of the motor clutch and the closing of the electric circuit, as tally illustrated and described in the KetteriLg and Chryst patent above mentioned.

A gear 37 is secured to the motor clutch and meshes with an intermediate gear 38, which, in turn, meshes with a gear 39, secured to a main cam shaft 40.

Through this gearing and the motor clutch, the motor, (not shown), drives the shattt 4:0 one rotation for each adding operation of the machine.

Since in some cases it may be desirable to operate the machine by hand instead of by a motor, a manual operating mechanism is pr vided in addition to the motor driving mechanism.

A hand gear 41, (Fig. 2 is mounted upon a stud 42, carried by the n'zachin de frame, and may be held against longitndnal movement on the stud in any manner.

The gear ll meshes with a gear 43, rotatably mounted on a stud in the machine frame. This gear meshes with a gear fastened on the shaft 4L0. The ratio of the gears L1, 428 and 44 is such that two rotations of the gear 4C1 causes a half rotation of the gear L8 and one rotation of the gear 45.

K3; and

Only one bank of amount keys has been shown (F 6). The number of banks of keys to be used depends upon the capacity desired. The parent application shows six banks of {mount keys, one bank of transaction keys, one bank of department keys and one bank of clerks keys.

The construction of the k ey bank is 'very sum de cribed in z 11' to that shown ant patent granted to applicant on October 9, 1917, No. 1245.,17'0.

on a shall: sup- I Bi l 10 so secured to the differential by the in 1 @116 driver ed first Ci'GCiUflf'jG an d then coun- :e (fl s. J and k n the sh at t 83 and associated with the driver r. ped plate 85 his. 3) having in therewitzi a gear seg'nnznt 86 arranged to mesh with teeth 57 on a slide 88 mounted for vertical reciprocation on the shaft and a shaft 89.

Also loose upon the shaft 83 and associated with the plate 85 is a lever having a right angle flange 91 arranged to contact with either the zero stop pawl 61 or the stem of a depressed key 50. Pivoted on a stud 92 on the plate 85 is a lever 93 the forward end of which engages the under side of the flange 91. This lever 93 also carries a stud 94 which normally engages a slot in the lever 90. Also pivoted upon the stud 92 is a latch pawl 95 the tail of which normally engages a shoulder 96 (Figs. 3, 4 and 6) on the driving segment 84.

- This pawl 95 is connected to the lever 93 by a pin 97. A compression spring 98 between the plate 85 and the upper end of the lever 90 holds the pawl 95 in engagement with the shoulder 96.

When the parts are in the positions shown in Fig. 6 a clockwise movement of the driver 84 rocks the plate 85 and lever 90 until the flange 91 engages the stem of the depressed key. This arrests the clockwise movement of the lever 90 but the driver 84 continues to move clockwise. This continued. movement of the driver 84 rocks the pawl 95, with the stud 94 as a fulcrum, until the tail of the pawl is disengaged from the shoulder96. The above movement of the pawl 95 causes its nose to engage a notched plate 99 in a position appropriate to the key which has been depressed.

The nose of the pawl 95 is now held and locked in engagement with the plate 99 due to the fact that the rear end. of the pawl rides upon the outer periphery of the driver 84.

The above described differential setting of the plate 85 causes its segment 86 to set the slide 88 to a position corresponding to the value of the key depressed.

If the key is not depressed the zero stop pawl 61 operates the latch pawl 95 to stop the plate 85 and lever 90 in the zero position. When, however, a key is depressed, the arm 56 through its engagement with the pin 60, as

previously described, rocks the pawl 61 out of the path of movement of the flange 91 so that the differential mechanism may be set according to the value of the key which is depressed.

In order to allow time for the latch to break in the Zero position, so that the actuating slide 88 will not be moved whenno amount key has been depressed, the plate 85 carries a stud 105 (Fig. 8) engaging a slot 106 in the forward edge of the slide 88. It will also be noticed that the segment 86 is not in engage ment with the teeth 87 when the parts are in normal positions.

The slot 106 is arranged so that part of it is concentric with the center of the shaft 88. When the plate 85 is oscillated, the stud 105 slides in this concentric portion until the segment 86 engages an edge 107 just below the lower tooth 87. If there has been no key depressed, and the zero stop pawl 61 causes the latch pawl 95 to become disengaged from the driver 84 in the zero position, the plate 85 will be rocked slightly, but not enough to cause the stud 105to become disengaged from the concentric portion of the slot 106. Consequently, when the latch pawl 95 is disengaged at the Zero position, the stud 105 and slot 106 keeps the slide 88 from being moved out of normal position.

If any key in the bank has been depressed and the plate 85 is operated beyond the zero position, the stud 105 moves in the slot 106 until the segment 86 becomes engaged with the teeth 87. The segment 86 then moves the slide 88, thus causing the stud 105 to be disengaged from the concentric portion of the slot 106 and to engage the remaining portion, and finally become entirely disengaged from said slot.

After the totalizers, hereinafter mentioned, have been engaged with teeth 108 on the rear side of the slide 88 the cams 75 and 76 cause the shaft 83 to be oscillated counter-clockwise to its home position. As the driver 84 moves toward its home position, the tail of the pawl 95 again becomes engaged with the shoulder 96 and its nose is disengaged from the plate 99. At the same time that the pawl 95 moves clockwise,'a surface 109 (Fig. 4) of the driver 84 strikes a pin 110 on the plate 85, thus restoring this plate and the lever 90 to normal positions. The pin 105 by its engagement with the slot 106 restores the slide 88 to normal position.

During total and sub-total operations, such as are fully illustrated and described in the parent case Serial Number 299,112, and the divisional application, Serial Number 174,858 above mentioned, the driver 84 and associated parts are given two oscillations, clockwise and counter-clockwise to perform their necessary functions during such operations. Consequently the driver 84, plate 85 and lever 90 are swung first clockwise and then counterclockwise twice in rapid succession when the machine is motor driven. This rapid movement tends to whip the latch pawl 95 away from the shoulder 96 of the driver 84 as they change their direction of movement at the lowest point of their travel.

To counteract this whipping force and to insure a positive couple between the latch pawl 95 and the driver 84, a guide 111 (Fig. 6) is secured to the key frame 51 adjacent the plate 99 and has its lower end extended beyond said plate at a point just below the upper end of the zero stop pawl 61. The lower end of the guide 111 engages a pin 112 on the latch pawl 95. When these parts are in engagement the tail of the pawl is held in contact with the shoulder 96 of the driver 84. Since the latch pawl changes its direction of movement just below its zero stop pawl 61, it is prevented from whipping away i is depressed, or with the end of a from the driver by the pin 112 and guide 111. The plate 111 is not necessary at the upward limit of the latch pawls movement for the reason that at this point the pawl and asso ciated parts are held by the engagement of the surface 109 of the driver 8% with the pin 110 on the plate 85.

A whipping action such t scribed may also occur as the lawl moves intermediate the point marking the limits of its upper and lower positions, due to a sudden stopping or starting movement of the driving segment 8% or to a sudden. reduction. and increase of speed. In order to counteract this whipping action a weight 113 (Figs. 3 and is loosely mounted on the stud 92, the potential force of which holds a recess therein a pin 11 1 on the lever 90. Any sudden movement of the lever 90 and the plate 85 that might tend to separate them and dislodged the pawl 95 from the shoulder 96 is counteracted by the lagging force of the weight 113 against the pin 114: which holds the lever 90 and the plate together, thereby retainim the posi' 've couple between the pawl. 95 and its dr segment 84, except when said couple b en posi e 91 with tivel b 7 the en 'a ement of the lie.

Beam mechtmzsm The indicators and printers hereinafter described are positioned by means directly controlled by the differential actuators just described through connections arranged to move said indicators and printers directly from one position to another. This is accomplished by devices operating intermediate the plate 85 and the indicators and printers in such a way that the differential positioning of said plate determines the position to which the indicators and printers are to be adjusted, and after said adjustment the plate 85 is allowed to return to its normal position without altering the position of the indicators or the printers.

A lever or beam 120 (Fig. 6) is pivoted on a stud 121 carried by the plate 85. The beam 120 is curved to it around a hub 122 loose upon the shaft 83 and has at other end a slot 123 engaging a pin 12 1 on a two-armed plate 125 secured to the hub 122. Connecting the arms of the plate 125 is an arcuate section having a slot 126 eccentric to the shaft 83 which slot receives a pin 12'? carried by a lever 128 pivoted on the shaft 80. The upper end of the lever is secured to an indicator carriage 129.

The plate 125 also has an integral gear segment 130 meshing with segment arm 131 secured to one of the sleeves 132 on ashaft Also secured to the sleeve 132 is an arm 13% (Fig. 8) having a gear segment 135 used. to set the printer devices.

In Fig. 6 the parts are all shown in their zero positions. If the machine is now perated with the 9 or top key 50 depressed, the plate 35 moves until arrested by this depressed key. The end of the beam 120, which is pivoted. to the plate 85, is carried clockwise and, because of the opposition afforded by the hub 122, the rear end of the beam is lowered a corresponding extent. This movement of the beam 120 is transmitted through the pin 124;, plate 125, slot 126, pin 127 and lever 128, directly to an indicator carriage 129 to move it from the zer position to the 9 posi tion, this being a clockwise movement of the lever 128 (Fig.

Cooperating with the beam 120 is a roller (Fig. 5) carried by an arm 137 secured to the shaft 80. Also secured to the shaft 80 is a lever 138 carrying two rollers 139 which cooperate with cams 1-10 and 141 secured to the shaft 410. As the shaft is rotated the cams 1 O and 1 11 rock t 1e lever 13S, shaft 80 and arm 137 so that the roller 136 is carried up against the underside of the beam 120 to insure that the upper curved side thereof contacts the hub 122. This movement of the beam is completed just at the instant the driver at reaches the end of its clockwise movement and insures the correct positioning of the beam. Then, during the counter-clockwise rotation of the shaft 83, the roller 136 is carried away from the beam 120 and, when the plate 85 is restored to its normal position, the beam 120 and plate 85 are carried down as the pivot stud 121 is lowered, so that at the end of the operation the upper curved side of the beam 120 is quite some distance from the hub 122.

If on the next operation a key of lower denomination than 9 is depressed, say for instance the 5 key, the end of the beam connected to the plate 85 is carried up until the latch mechanism is tripped by the depressed key. The roller 136 is then carried into contact with the under side of the beam and raises the beam the rest of the distance necessary to bring the upper curved surface thereof into Contact with the hub 122. This through the intermediate connection rocks the lever 128 counter-clockwise so that the 5 indicator will be in the proper position. The roller 136 is then carried away so that as the plate 85 is restored to its normal starting point, the end of the beam 120, which is attached to the stud 121 moved downwardly without any interference from the roller 136.

By the use of this beam mechanism it will be clear that the indicators are allowed to remain in the position to which they have been set at one operation until a subsequent opera tion of the machine.

By means (Figs. 6 and 8) of the segment arm 131, sleeve 132, and arm 134: and segment 135, the printing wheels are set through the beam driven plate 125, and are allowed to remain in the positions to which they have been set at one operation until a subsequent operation of the machine.

In order to align the plate (Fig. 6) and the indicators and printers there is provided an aligning bar 149 cooperating with notches 150 in the arcuate section connecting the arms of the plate 125. This bar 149 is integral with an arm 151 secured to the shaft 89. There is another arm (not shown) like the arm 151 which is also secured to the shaft 89.

Secured to this shaft 89 is an arm 152 to which is pivoted a pitman 153 (Figs. 6 and 7) carrying a roller 154 engaging a cam race 155 in a disc 156 secured to the shaft 40. Up and down movement of the pitman 153 by the cam race 155 rocks the arms 152 and 151 to cause the aligner bar 149 to become engaged with and disengaged from the notches 150 at the proper time.

T otalz'sers The only totalizers shown in this application are the pinions 160 on the shafts 161 (Figs. 3 and 6). These shafts 161 are arranged to move the pinions 160 lnto and out of engagement with the teeth 108 on the different-ial slide 88 at the proper time to cause addition on the totalizer pinions and also to cause them to be reset to zero when desired.

Indicators Fig. 6 shows two sets of indicators, 162 for indicating toward the front of the machine and 163 for indicating toward the back of the machine. Both sets of indicators are carried by the indicator carriage 129. These indicators bear indicia corresponding to the captions on the keys which are used on the machine.

Movement of the lever 128 positions the indicator 162 with relation to the slot 164 in the cabinet so that the proper one of the indicators may be raised for exposing to view the indicia thereon, corresponding to the keys which have been depressed.

In order to further align the indicators 162 and 163, the arm 151 (Fig. 6) has an integral arm 165 having a cam slot 166 engaging a roller 167 on one of two arms 168. These arms are secured to a shaft 169 and support a channel bar 170 and a rod 171. Pivoted on the rod 171 is a spring actuated pawl 172, guided in slots (not shown) in the bar 170. The pawl cooperates with notches in the indicator carriage 129. There are as many pawls as there are difierential actuators.

As the pitman 153 raises to disengage the bar 149, the slot 166 lowers the bar 1 0 and rod 171 and disengages the pawl from the carriage, to permit said carriage to be moved by the beam 120. VVhen the pitman is lowered the pawl 172 is again engaged with the notches 17 3 and aligns the indicators.

Printer Fig. 8 shows type wheels 175 and 176 cooperating with platens 177 and 178 respec tively. intermediate the type Wheels 17 5 and 176 is a gear 179 having secured thereto a segment 180 which meshes with the previously described gear segment 135.

By means of the gears 179 and 180 the movement of the gear segment 135, under control of the differential actuator and beam 120, is transmitted to the type wheels 175 and 17 6 so that they will be set in the position according to the value of the key which has been depressed.

After the type wheels have been so set the wheels 175 are moved into contact with the platen 177 and the wheels 176 are moved into contact with the platen 178 by means not illustrated or described here because they form no part of this present invention. For a description thereof reference may be had to the parent application, Serial Number 299,112.

Operation A. very brief description of an operation will be given. After the proper key 50 has been depressed and the machine is released the motor worm 32, if the machine is motor operated, through the mechanism in Fig. 1 drives the cam shaft 40 one rotation in a clockwise direction. This rotation of the shaft 40 through the mechanism in Fig. 4 rocks the driver 84 clockwise, which through the latch pawl 95 (Fig. 3) rotates the plate 85 and lever 90 clockwise. This, through the segment 86 positions the slide 88 to a position corresponding with the notation on the key depressed, after which the totalizer pinions 160 are moved into engagement with the teeth 108.

The beam 120 then positions the indicator carriage 129 so that the proper indicators are moved underneath the cabinet opening 164, and also through the segment 130, segment arm 131, arm 134 and segment 135 causes the type wheels 175 and 176 to be set in the proper positions. The segment 84 then is rotated counter-clockwise to its normal position thus restoring the plate 85 and lever 90 and con sequently the slide 88 to normal positions whereby the amount corresponding to the value of the key depressed is entered into the M totalizer pinions 160 which are engaged with the teeth 108. The pinions are then disengaged from the teeth 108. t

The beam actuating roller 136 is moved away from the beam prior to the restoration of the segment 84 so that the end of the beam which is pivoted on the stud 121 may be moved downwardly without interference from the roller 136. At this time the beam pivots around the pin 124 thus permitting the indicator carriage 129 to remain in the position in which it was set and also permitting the plate 125 to remain in the position in which it was set, which consequently allows the type wheels 175 and 176 to remain in their set positions until a subsequent operation of the machine.

Should the machine be hand operated instead of motor driven, the drive is then by means of the gearing in Fig. 2.
