cAsn-nneisrnns ran-noruiarine MECHANISM.

7 To all whom it"mag cancer n:

Be it known that I, Fnnnnnicir Enwann MILLER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Cash-Registers Tab-Actuating Mechanism,

' of which the following is a full, clear, and

exact description, such as will enable others, skilled in the art to which it appertains, to make and use the same, reference being had to the accompanying drawings. forming part of this specification.

The present invention has relation to improvements in cash registers, and 18 more particularly an nnprovemcnt over Patent- 1 No. 1,080,162, to E. Patten, dated Deeration forming the subject matter of this invention, there is no limit to the amount that may be registered and indicated. In

order to attain this increased capacity, l

have invented a new mechanism for reg1s' tering and indicating dollars and cents, the five cent and dime mechanism remaining unchanged.

By virtue of the present 'mprovement, I have secured greater compactness and greater simplicity of construction, the mechanism whereby this is, done being more easily operated and more cheaply manufactured. r

Further objects will be better apparent from a detailed description of the invention in connection with the accompanying drawings, in which-- Figure 1 is a side elevation of my invention. i

F igure 2 is a plan View with parts in section and other parts, having no direct bearing on the present improvements, omitted.

Figure 3 is a detail view showing the liftingbail and its connection with the dollar.

segment, also the lockingmeans for the handle.

Figure at is a vertical section on the line 1 4 of Figure. 1.

. Figure 5 is an end viewof the indicator lifting bar and associated mechanism.

Referring now to the drawings, 1 represents the frame of the machine in which a lifting bail 2 is trunnioned, and 8 is a handle pivotally mounted on a plate 1, trunnioned in the frame of the machine. A link 5 is pivoted at the rear end of the handle '3, said link being adapted to come beneath the stem 60f any selected indicator tab as the =-handle 3 is swung to position over the proper notch of the frontplate 7, in order to indicate the amount registered. WVhen the handle is swung to the position shown in igure 2, its link 5 will be free of the liftingtabs, and this latter position is the position of the handle when it is desired to indicate and register dollars only. Obviously, when the handle is in this latter position, if the mechanism whereby the dollars are indicated is not set up, it would be possible to depress the handle and consequently open the cash drawer without indicating or recording any amount, which is the case in Pat. No. 1,080,162. In order to prevent this, the handle 3 when in the position shown in Figure 2 is locked against movement by means of a depending finger 8, mounted on arock shaft 9, said finger 8 in its normal position being immediately over the link 5 and remaining in this position until an amount is set up in the dollar actuating mechanism, when said arm is released, as will more fully hereinafter appear.

Secured against theside of frame 1, is a plate 10, on which plate is mounted the mechanism for setting up or controlling the amount'to be indicated by the dollar or integer tabs 11, arranged in a bank and mount ed in plates 12, on one side of the'machine. The controlling mechanism, to which this 1 invention particularly relates is as follows:

A plate 13 ismounted on the plate 10 by means of studs 14, it, said plate being provided with slots 15, 15, whereby it is Specification of Letters Patent, Patented Aug. 29, 1922. 2 Application filed August 2, 192 0. Serial No. 400,595.

slidable back and forth on the plate 10, and mounted above said plate on the end of the rock shaft 9 is a finger 16, provided with a pin 17 on its free end, said pin being held. in contact with an inclined edge 18, formed on the plate 13 by a spring 19. A spring 20 tends to hold the plate 13 in its home position, at which time the finger 8 is in position to lock the link 5 on the handle 3, when said handle is swung to a position for indicating dollars, as shown in Figure 2. A controlling handle 21 is pivoted at 22 near the lower end of the plate 10, said handle being provided with an arcuate portion 23, having a number of teeth t on its edge equal to the number of dollar tabs 11. The end of the plate 13 beneath the tabs 11 is provided with a pair of spaced-apart ears 24- wherein is mounted a lifting bar 25. The plate 13 is provided with a pin 26 engaging the handle 21, and upon oscillating said handle the plate 13 will be reciprocated to a position commensurate with the amount that said handle has been oscillated, and the lifting bar 25 will, of course, be carried with the plate 13 and assume a position under the stem of one of the indicator tabs-11.. In order that the handle 21 may be moved step by step, so as to bring the lifting bar 25 under any selected indicator tab, a pawl 27 is mounted adjacent the arcuate portion of the handle 21, which has its nose in the uppermost or first tooth '6 when the handle 21 is in its home position; said handle can now be oscillated to the proper position to effect the lifting of any dollar tab, and in Figure 1 the handle is shown dotted in the proper position to raise the fifth tab from the rear, or the five dollar tab.

A second reciprocating plate 28 is p0sitioned beneath the plate 13, said plate 28 being secured to the plate 10 by studs 29, 29 operating in slots 30, 30. The plate 28 is provided with a pin 31 near its forward end, said pin resting within a slot 32 in the handle 21, and as the handle 21 is oscillated, the plate 28 will likewise be reciprocated to a position corresponding to "the amount of oscillation of the handle 21.

A yoke 33 is mounted on a rod 3%, said yoke having an upwardly projecting arm 35, the latter carrying a tooth segment 30 adapted. to engage a gear 37, whereby the dollar wheels are rotated. The yoke 33 is also provided with a downwardly projecting arm 88, the extremity of which arm 38 is provided with a pin 30, projecting through an arcuate slot -10 in. the plate 10, and also traversing a slot 4C1 in the rear end of the plate 28. It is thus seen that as the handle 21 is oscillated and the lifting bar 25 positioned beneath a selected tab 11, the locking finger 8 will be released, and the plate 28 will be reciproeated to oscillate the yoke 33, so as to rock the dollar segment 36 to a position to register the amount of dollars in the counter wheel that have been set up on the indicator tab.

After the lifting bar is positioned and the dollar segment correspondingly oscillated, the handle 3 is depressed, whereby the bail 2 will be raised to effect the lifting of the designated dollar tab and restore the thillar segment to its home position, during which operation the gear 37 will be rotated and. the proper number of dollars registered in the counter wheels by the actuating mech anism which is as follows:

A rocking frame 42 is pivoted on the rod 3 1 and is provided with an L-shaped slot 13, through which pin. 4, 1 projecting from the bail 2 extends. The rocking plate 42 is provided with an extension 45, having a pin 46 in its extremity, which pin traverses an inclined slot 17 in a lifting plate 48 slidingly secured to the plate 10. by means of studs 49 l9 traversing slots fill-50. The forward end of the rocking plate 412 is provided with an arcuate slot 51, having an angular extension 52, which is trav rsed by a pin 53, projecting from a pawl the nose of which pawl upon being oscillated is adapted to enter anyone of ten serrations 55 on the lower edge of the plate 13. ()n depressing the handle 3 and raising the bail 2, the pin 1-4; will. be carried upwardly. traversing arcuate slot in the plate 10, and rocking the plate 12, thereby lifting the plate 418, which latter in turn will lift the lifting bar by virtue of i leg 57 eng: ring a pin 58 projecting from the lifting l tr 25. the plate 42 is rocked the pin will be forced out of the slot into the slot 51, thereby rocking the pawl until. its nose engages one of the serrations and which will hold said pawl in this position until the rocking plate again returns to its home position, which it will do, upon releasing the handle l. As the bail 2 is raised, the pin t1 thereof will engage a projection 69 on the yoke 2-33 and force said yoke back to its normal position, during which time the segment 36 registering dollars in the counter wheel, the gear 37 having previously been thrown in mesh with the teeth of said segment 36. The mechanism whereby the gear 37 is caused to engage with the teeth of the segment 36 is the same as that set forth in. the aforesaid Patent No. 1,080,162. The depressing of the pin will likewise cause the pawl 27 to be disengaged from the teeth of the handle 21, since said pin 52? engages the rear leg of the pawl .27, ()hvionsly, he restoring of the yoke 53 to its normal position will draw on the plate 28 and likewise restore said plate to its normal position, and in doing so, will likewise restore the handle 21 to its normal position by virtue of the pin 31 which engages the slot 32 of said handle. However, the plate will not be restored to its normal position on depressing the handle permit the pawl27 toagain-engage the teeth of the handleQl, and the pawl 54 to again become" disengaged from the serrations 55, atwvhichtime theplate l3 will be restored to its normal position under the influence of the springQO.

"Th'e plate' 28 is provided with a series of teeth 59 on its upper edge above which is mounted 'a locking paWl- 60,which pawl is held out of engagement with said teeth by means of pin 61 which bears against the lower "edge of an opening in the rocking plate42, but upon rocking the plate 42, said pawlwill be depressedunder the influence of a" spring 62, and willengage'with the teeth 59'thereby locking the plate-28 against forward movement when the mechanism is set, but permittingsaid plate 28 to return to itsnormalpositionat the propertime. The

pawl is provided as a safety device to prevent tampering With the mechanism or accidentallyderanging the-same A release handle 63 is slidingly mounted on the handle 21 and said handle 63 is provided with an arcuate extensionfia upon whichapin 65, projecting from the pawl 27, bears. In whatever'position the handle 21 may beoscillated, the arcuate portion of the handle 64- will' engage with the pin 65, so that, at all times, the handle 63 may be raised in order to lift the pawl 27 out of engagement with the teeth 25 of the controllin handle. The handle 63 therefore may be operated to release the pawl 27 and step back the handle 21 any number of spaces,

should an error be made in setting said handle 21.

It is understood that a bank of tabs may be mounted on the side of the frame opposite to the dollar tabs with actuating mechanism of its own, and said tabs may be adapted to indicate odd cents or higher multiples of dollars for instancefrom 10 (ten) to 90 (ninety) dollars inclusive. In this manner, the capacity of the present machine may be readily enlarged, by merely adding another bank of dollar tabs to indicate up to $99.95 (ninety-nine dollars and ninety-five cents), or the machine may be provided with additional banks of tabs, and its capacity increased to any amount desired. It is thus seen that my invention consists of a complete registering and indicating device, and if desired, could constitute the sole registering and indicating mechanism of a cash register. Obviously,'it is within the purview of a skilled mechanic to modify the invention Without, in any way, departing from the'spirit .ofjthe same. 7
