Each actuator has gear teeth 16 on the rear hub portion for transmitting motion through the pinion 17 to one :of the telescoped shafts 18, 19"and-20 Eachactuator is normally limit of attached held at-z'ero bya spring 21 at the its upward movemen by the pin 22 untilit engages a pin 26 and further pressnre'on the key causes the entire actuator 14: to swing about itspivot 13: -The independent movement of the digit stop on its pivot 24 extends the inner end 29 so that it projects into the path of the fixed stop 31. A3 latch member 30 having a limited rotar'y movement has its end extending into thepathof move'mentof the digit stop29 when the latter is in the projecting position. Thelatch' 30 governs a pawl 33 which is held out or engagement with the ratchet 36by1 a pin 34c on the pawl 33 resting in a notch35 in the latch member'SO. As the projecting digit stop 29 moves downward toward the fixed stop 31, it strikes the end V of latch30 and moves it against the fixed stop 3l, th us serving to arrest the motion of the actuator. Movement of the latch 30 has released the p111 34 from the shoulder 35 and has allowed the pawl member 33 to .be'cas'tinto the teeth of the ratchet bar 36 "by the action of spring 32. The pawl 33 and :theratchet 36 may also serve as means ,for'ar'r'esting the movement of theactuator '14,..but in; addition these parts perform a very useful function of preventing incorthe actuator while the same" rect operation of is returning to thezero position, as Wlll be described later.

' occurs,

it pawl member 39 mounted loosely on the shaft 38 is pressed into engagement with .(ratchet bar 41 by the spring 42. As soon as the actuator begins its downward move- .ment the pawl 39 becomes active to prevent return movement'of the actuator, and when the "actuator has reached the limit of its downward movement by the digit stop 29. striking the latch 30 and being stopped by the fixed stop 31, the actuator will be locked against either forwarder return movement and will remain so :ed until the pawl 39 is disengaged from the teeth of the ratchet bar 41. This is due-to the fact that the digit stop 29 cannot be retracted until a slight upward motion of the actuator 14:

and the pawl '39 prevents such upward motion by engaging the teeth of ratchet 11. ,This locking action of the ac-- tuator in its arrested position prevents a second operation of the same actuator either by mistake or through design until the entire machine is cleared by restoring to the by the operator.

zero position. Any change of the setting of the actuator is also prevented until the machine is cleared. I

Each actuator 14 is provided with a pawl and ratchet 11 to operate independently to prevent return movement of the respective actuators until a common means in the form of a release key 46 simultaneously releases all the pawls 39. Shaft 38 has rigidly attached thereto an operating arm 15 which to each pawl 39 is a short arm lever 13 provided with a pin 44 positioned in front of its pawl 39 and adapted to disengage its pawl. 39 from the ratchet teeth when the release key 46 is operated, The release key extends through an opening 47 in the casing and is provided at its outer end with a finger piece -18. A spring 19 interposed between the finger piece 38 and the casing prevents any interference of the pins 44k with the pawls 39.

When the actuators are released by depression of the release key, they are free to return to the zero position under the influence of springs 21, as eachpawl member. 39 is prevented from interfering; with the return movement by being held out of engagement with the ratchet member 41 through the action of latch member 52 which engages and holds a pin 51 attached to the pawl member 39, as shown in Fig. 2.

Each actuator must return completely to zero before it may again be depressed as the pawl member 33 rid-es over the ratchet, 36

and. is.not freed therefrom until thelimiti of upward movement is again reached. As the. actuator approaches the zero position, a pin 37 fastened to the actuator disengayres the" pawl 33' from its ratchet 36 and allows the latch member 30 tohold it in that position by engagement of the shoulder 35 with the pin i I Assoon as the actuator is freed from the control of'pawl 33, it is'again placed under the influence of pawl 39. -This is accomplished by a pin 53, also mounted on the actuator in such a position thatjas the actuator comes to zero, the pin 53 will raise the latch 52 and allow thepawl 39 to be cast into the ratchet 41. It can be seen that the, above described mechanism places the actuator under the con- .trol of pawl 39 and ratchet 41 to prevent a return movementof the actuator after it has once been moved from inltialposition. The t operator, therefore, depresspgit until it can be depressed no further. A

this point it is completely locked until positively released The arrest of the downward movement of the actuator places the latter under the control ofpawl 33 and ratchet 36 and the reactuation priorto the completion of the return stroke is thereby prevented. -As ,the zero position is reached,

Adjacent ware-operative to perform their functions re-' renderedinactiveand the actuatoris again seen that the two pairs of pawls and ratchets gardless' of the extent of movement of the actuator That= is, the full desired moveent,,in both directions is insured whether said-movement isthrough a very small arc pc throughanarc nine times as great.

.ThelsalQi dicator is operated. directly hy the movement.of the actuator and consists of: a flexible strip etwith numerals marked Ktherenpoh corresponding in value to the digit keys; This flexible strip passes over a --.dr um;;55iinsidethe'casing so as to expose the proper number at the sight opening corresponding to the position to which. the

actuator has-been moved. This strip 54 passes over a roller 56 and is held-under tenjs1on by spring 57 which plays out vvvind takes are three actuators, each having its own set up the strip 5a inaccordance with time move- .nt. of the indicator to which it is att "hed. in the particular machine illustrate of keys, controlling mechanism, indicater andtotahzing mechanism and it is 1 evident that-a machine of anydesired caeating the. actuators withtheir wmechani'sm.

pacity may be constructed by merely dupliappended The operation of the machine will now he d'escribed; When it is desired to register a :saleor' other transaction which might be represented in dollars, dunes and cents, the

digit keycorresponding in value to'the number of dollars is depressed. Depression of --the.key causes a digit stop 29 to be extended into'the path of the latch 30 and the fixed istop' 31, and as further independent'movemerit of the key is prevented by the pin 26,

the entire actuator will be swung downward huntil the digit stop29 engages the latch 30 xpre sse'd. When thedigit-stop' has come into war and'is positively stopped by the fixed stop 31. .-Downward movement of the actuator has moved the sale indicator so that the at the sight opening facing the operator.

As the actuatcris arrested it'releases the pawl permitting it to engage the teeth {of the ratchet to aid instopping the. actuator and also to put the actuator under the conh ther-5515651 pawl, and treatis s is-= placed undenthe fcontrol of 'thefirst pawl andratchetrneans 39-l1. It-will' thus be 'trol of the pawl and ratchet mechanism to insure a return to zero. The dime actuator may a now be .opcrated by depressing the proper key corresponding to thefnumber of dimes to be registered. A similar locking of the actuator at the end of its movement occurs and a transfer of control from the one pawl and ratchet mechanism to the other is made in a manner similar to that of the dollar actuator; The cent actuator is then operated by depressing the proper key and performing the same operations described in connection with the operation of the dollar actuator. After all the keys that are neces sary to register a transaction have been depressed, the common release key is operated. This allows the pawl and ratchet mechanism 33-36 to assume control of the movement of the actuator while the control by the pawl and ratchet mechanism has been suspended, and a return to zero is necessitated. v i hen the actuator returns to zero, the pawl. 33 is removed from control and'the pawl 39 is placed n control. It is thus seen that" a by the arrangement of the controlling mechanisms and-the possibility "of erroneous or incomplete operation is reduced to a minimum. t

It is apparent that many and various changes maybe made in the details of construction herein described and illustrated without departing from the spirit of the invention.
