CASH-REGISTER.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, Trio AS CARROLL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

The present inventions relate more particularly to that portion of the mechanism of cash registers known as the transfer mechanism for the counters and has among its objects to provide improved devices for insuring the accumulations upon the counter of all of the amounts which have previously been entered upon the machine, before the proprietor of the machine may take a reading from the counter. Such a device is particularly applicable to that class of machine wherein the transfers are one operation behind, that is, the transfers which have been tripped in the last transact-ion are notturned in until the first part of the next operation of the machine, so that if the proprietor should forget to give the machine an extra operation at the end of the day when he desires to take the final reading from the counter, he might thereby secure an erroneous reading from the fact that some of the transfers have not been turned in as above described; and it is the purpose of the present improvements to prevent any such reading of the counter until all the transfers have been turned in.

More specifically stated, the present invention embodies a revoluble transfer controlling member for the registering wheels and means for preventing the counter wheels from being read until this transfer member has been operated to turn in the transfers, and in another aspect, comprises a hand operated means for operating the transfer mechanism which hand operated means also may operate a shutter to expose the registering wheels, these parts being combined with mechanism to compel operation of the transfer devices as an accompaniment to the operation of the shutter.

The present application embodies certain subject matter which is common to two other and co-pending applications filed by the same applicant, of which applications Serial No. 264311, filed June 9, 1905, will be designated as Case B and aoplication Serial No. 26 1,592, filed June 10, 1905, will. be designated as Case C, and in both of said cases the present application will be referred to as Case A; it being intended to claim broadly in this present Case A the subject matter which is common to these cases and is claimed specifically in the other two, all three of these cases relating to the same general objects set forth above, but comprising differentmeans for accomplishing the general broad result.

\Vith these and incidental objects in View, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in appended claims and preferred forms of embodiment of which are hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

Of said drawings: Figure 1 represents a top plan view of the counter of the machine to which these improvements are applied. Fig. 2 represents a detail view of the counter shutter and gearing for operating the same. Fig. 3 represents a detail view of a part of the locking mechanism. Fig. l represents a detail view of a single tooth locking disk. Fig. 5 represents a detail view of one of the counter wheels and its transfer elements, and Fig. 6 represents the gearing for operating the transfer shaft.

These particular improvements are shown as applied more specifically to the counter of a cash register set forth in English Letters Patent issued to Frederick L. Fuller, No. 22535 and bearing application date of October 19, 1904:, and reference may be had to said patent for a complete and detailed description of the general construction of the cash register. In this patent an operating lever is first given a complete oscillation back and forth to release any previously depressed keys and store up power in the spring motor and then the desired keys are depressed according to the amount to be registered and finally a special key depressed which effects the release of certain operating segments which move to differential positions determined by the keys and these differential movements are transmitted to the counter. This operation of the machine merely effects the tripping of certain transfer elements and the actual turning in of Fatented Mar. 8, 1910.

these transfers does not take place until the next operation of the operating lever. This being the general operation of the machine as disclosed in the aforesaid patent the particular operation of the parts involving the transfer mechanism and forming part of the present improvements will now be described.

In F l the various counter wheels are shown having numerals on their periphery in the ordinary manner, and in front of said counter are two horizontally extending shafts (see Fig. which may be called the transfer operating shaft and a transfer star-wheel shaft 11, the counter wheels themselves being mounted upon the transverse shaft 1.2. Each counter wheel has fast to it duplicate tripping teeth 13, (there being two of these teeth since the counter wheels bear a double series of numbers and of course two transfers take place at each revolution of the wheel). The tripping teeth 13 of a wheel of lower order strikes the star-wheel l-l when a transfer is to occur and this starwheel l l is by a sleeve connected to a similar star-wheel which when the star-wheel 1 tis rocked by the tripping tooth 13 is so rotated as to bring one of its projecting points into the path of its corresponding transfer operating cam 16, so that upon the revolution of such cam it will engage the starwheel 15 and by revolving the same when it comes in contact therewith will cause this star-wheel to give a unitary transfer movement to the next higher wheel, all as set forth in said patent. These transfer cams 16, are as shown in Fig. 1, spaced along upon a sleeve which is mounted loosely upon the aforesaid shaft 10, there being one transfer cam for each whee The normal operation of this transfer shaft 10 is effected by means of a segment gear 21, (see Fig. (3) fast to the driving shaft 22 to which is attached the oscillating operating lever as described in the aforesaid patent, and this segment gear 21 meshes with apinion 23 fast upon the end of the aforesaid shaft 10. A pin (see Fig. 1) extending upward from the shaft 10 projects into a notch formed on the lefthand end of the aforesaid sleeve 20. Thus upon the oscillation of the driving shaft 22 by the oscillating lever, the segment gear 21 rotates the pinion (in this case through nine-tenths of one complete revolution), and this rotates the shaft 10 to a corres ionding extent, and also through the pin 2 lrotates the sleeve 20 carrying all of the transfer cams so as to turn in the transfers in a manner similar to that described in. said patent. A separate hand means however is provided for operating this transfer can). sleeve 20 as will now be described.

Upon the right hand end of the shaft 10 (see Fig. l) is loosely mounted a sleeve upon one end of which is a knurled lfllOl) 31 and near the other end of which is a gear wheels to prevent their being read.

wheel 32 and the extreme end of which sleeve 30 is formed with a projecting portion 323 which is adapted to engage a corresponding cnt away portion 3i formed in the right hand end of the sleeve 20 so that when the sleeve 30 is forced to the left. these two parts 33 and 34: will couple together so that the rotation of the sleeve 30 by hand will also rotate the sleeve 20 to turn in the transfers in the manner above described. The sleeve 30 also has projecting inwardly from it a pin 35 which enan annular groove 36 formed in the shaft 10 so that when. said sleeve 30 f rced to the left the shaft 10 will also be forced to the left. although of course the shaft ll) may rotate independently of the sleeve 30. This same lateral shiftingmovement of the shaft 10 will carry the pin it (located at the other end of the shaft l0) into the recess 37 formed in a collar 3 mounted loosely upon the shaft 10, so as to permit the turning of the sleeve 20 independently of the shaft 10. Upon the other end of the shaft 10 and adjacent to the aforesaid pinion a single-toothed loching disk 4:0 shown in detail in Fig. -'l-. 'ilhc pinion is wide enough so as always to remain in mesh with its gear 21 during the lateral shifting movement of the shaft 10 by hand for the purpose of o 'ierating the transfer cams by hand as just descrilled. and in such case the single tooth disk M) is now shifted so far to the left that it engages between the teeth of the gear 2.1 and thus firmly locks said gear from movement so that the oscillating lever cannot now be moved to return the shaft 1.0 while the shaft is in this shifted position. The purpose of this lateral shifting of the shaft and the turning of the transfer cams by hand is to raise the counter shutter which nor mally conceals the counter from being read. and this shutter mechanism and its cooperation with the parts already described will now be set forth.

The shu.ter :emprises two sup 'iortiug arms which are pivoted upon the aforesaid shaft. which carries the counter wheels and these arms have extending between them a bar 51 which acts as a concealing flash or shutter for the counter Pouch a shutter is also shown in he aforesaid Fuller patent but the present improvements relate to controlling means for the shutter connected with the transfer n'iechanism so as to insure the transfers being turned. in before the shutter can be raised to expose the counter wheels. Mounted loosely on the shaft 12 by the side of the right hand arm 50 is a segment 52 which meshes with the previously described pinion S2, and e. tending upwawlly from this gear 52 is a shutter restoring arm 53 which engages a pin 54f projecting from the side of the right hand shutter arm 50. When the knurled knob 31 is turned as previously described, after having been shifted laterally to the left, he consequent turning of the pinion 32 will turn the gear segment 52 and will rotate the same so that its upper edge 55 strikes the said pin 5a and in the continued movement of the gear 52 thereby rocks the shutter arm and entire shutter backward about its pivot thereby raising the shutter to expose the counter wheels, the shutter being normally held in lower and concealing position either by its own weight or by a suitable spring, and being limited in its backward movement by striking against a suitable stop pin On the reverse rotation of the knob 31 and pinion 32, the gear segment 52 returns to normal position and its arm 53 strikes the pin 6% and positively returns the shutter to normal concealing position. Thus it will be seen that the real purpose of the knob 31 is to lift the shutter to permit the counter wheels to be read, and the very turning of the knob to effect this purpose gives sufficient rotation to the transfer cam shaft to turn in all the transfers which had previously been tripped, and during this time the main operating lever is locked from movement.

In order to place the controlling of the knurled knob 31 under the care of the proprietor alone, a lock is provided therefor so that when the key 60 is inserted into this lock and is turned, this will effect the turning of an arm 61 (see Figs. 1 and 3) sufficiently to withdraw said arm from the path of a pin 62 which is fast upon the upper side of the aforesaid sleeve 30, so that thereby the sleeve 30 may be rotated by the knurled knob in the manner described. However in order to compel the lateral shifting of the knurled knob and the consequent shifting of the shaft 10 the pin 62 normally stands within a recess 63 formed in the side frame 64 of the machine so that the knob cannot be turned until the sleeve has been forced. to the left far enough to carry the pin 62 out of its recess 63, and thereafter upon turning the knob, the pin moves around upon the inside surface of said frame (A and of course holds the sleeve 30 in its shifted position, and since this knob and sleeve can have only nine-tenths of a revolution, the knob 31 cannot again be withdrawn to the right to effect the release of the operating lever until it is completely rotated reversely so as to again bring the pin 62 to register with its recess (33, at which time the sleeve 30 will again recede to its normal right hand position either by reason of suitable spring tension or by being laterally shifted by hand, so that the machine th n stands in normal condition with the operating lever and driving shaft 22 unlocked.

vVhile the form of mechanism here shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
