THOMAS-CARROLL, or DAYTON, orrro, ASSIGNOR, BY MESNE rissrenmnnrs ro 'rI-IE NATIQN. AL CASH'BIEGISTEBACOMIPANY,Q OE D AYTON, onto, a conromrron or ApplicationliledJ'une 10,1905."Seria1No 26s 592.-

. Be it known that I, "Ti r onus CARnoLn, a

' citizenof the :United; States, residing at Day-i ton, in the coimtybf Montgomery and State of ()hio,'have invented certain new anduse "ful Improvements in CaslvRegisters, of

- which -I' declare the following to be a full, clear, and exact-description.

Thefpres'ent inventions relate moreparticularly to that portion'ofthe' mechanism of cash registers known as the transfer'mechani'smffor'the counters and has 'amongits obj ect s" to providefimproved devices. for insur ng the accumulations upon the counter of all oft-he ainountswhich have previously been entered upon the machine, before the proprietor of the machine may take a read Qingfrom the'counte'r. -'Such a device'is-par- I ticularlyappli'cable'to that class of machine wherein the. transfers are one o' erationbe hind, thatis, the transfers whic ,lia've been tripped the last transaction {are not' turned untilthefirs't part of the next operation of the ih'achine; so". that if, the proprietor shouldl 'forget to give the machine an extra operation'at the end of the daywhen hedesires to take the final reading from the counter,- he might thereby secure .an erroneous reading fromthe "fact that some of the transfers have'not been turned in as above described and it isthe purpose of the .prestion, this rotatable trans cut improvements to prevent any such reading of the counter until all the transfers have been turned in.

More specifically stated, the 'resentim provements comprise a'shutter or concealing the regi'stering'wlieels, with means for operating said shutter to expose the'wheels,

and means for preventing such operation of the shutter when .the'rotatable transfer operating mechanism occupiesa certain posier operating mechanism in the present instanceconsisting of the'revoluble transfer operating shaft which must first be rotated s'ufiiciently to turn in all I of the transfers before the shutter operating means may be operated; and associated with this mechanism is a device for lockingthe v transfer operating mechanism and the main operatingmechamsm of the machine'whil'e the shutter operating mechanism is operated to expose the registering wheels.

The present application embodies subject Specification Letters iaten'a V. v

co-pending applications filed by the same applicant, of which applications Serial N 0.

264,229, filed June 8, 1905 will be referred "to 'as case A,-and application Serial No. 264,411, filed June 9, 1905, will be referred indicated as above.

Patented Mar. 8,191l v matter which is common to two other and I With these and incidental objects in view,

the invention consists of certain novel features of construction and'combinations of parts, the essential elements of which are setforth' in ap' ended claims and preferred forms ofem o'diment of which are hereinafter specifically described with reference to thedrawings 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 gearing connected to the main drivin shaft for operating the transfer shaft, an Fig. 3 represents a detail view of the mechanism forthe counter wheels.

These particular: improvements are shown as applied more specifically to the counter of a cash register setforth in English-Let-' ters Patent issued to Frederick L. Fuller No. 22,535 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. 7 In this patent an o crating'lever'is first given a'complete osci'l ation back and forth to release any previously depressed keys and store up power in the spring motor and then the desired keys are depfessed 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 I ecsnaos fer e ements and the actual turning in ofticular operation; of the n erel effects the tripping of certain transthese transfers does not take place until the next operation of the operatin lever. This being the eneral operation the machine as d sclose in the aforesaid patent the pars arts involving the transfer-mechanism and orming part of the present'improvements will now, be described.

In Fig. "1 the various-counter wheels are shown havingnumerals on.. their periphery in-the' ordinary manner, and-in front of said counter is a horizontally extending transfer shaft 10 carrying various transfer: cams '16 forcausing the transfers'to he turned in by the rotation of the shaft 10 after the transfers have been tripped upon the normal reg- 'istering movement of the various register- 4 ing wheels. The operation of'this shaft 10 is efi'e'cted by means of a ear 21 (see Fig. 2) .which'i's fast u on the rivin shaft 22 to which driving aft isattache the oscillating operating lever as described in the said 5 Fuller patent, and this gear 21 meshes with :inions '23 ('seealso Fig. 1) fast upon the eft hand end of said 'shaft'lO, so that-upon the oscillation of the shaft 22 by the oscil I I lating lever the pinion 23 an'dshaft will} be-revolved to turn inthe transfers all{ as deinstance the pinion 23 and shaft 10 are capable'of being given-only about nine-tenths scribed in saidpatent, and in the present of-one complete revolution'whic'h is however 3 sufficient-to turn in allof the transfers sucoess e y i Y v The shutter mechanism for concealing the counter wh els will now be described.- The 1 col l'nte'r wheelslar'e' mounted upon the transverse shaft -.'i.2fand. also pivoted upon this shaft-I are tv i'siiarms' carrying between them-"a cross'i'iar 51 which servesas the flash orshutter tojchnceal the ceunterzwheels.

The right handarm-50 is formed with a double toothed projection 52 as shown in Fig.3, between which teeth there projects an arm 53 extending rearwardly from the rotatable barrel of a lock 59, the barrel of this lock being oscillated'by means of an -"--ordinary -key 60, andwhen 'so oscillated,

"shown'in said Fuller patent for the purpose of -i1ornially concealing the reading on the bounterlwheels and this shutter therein is also operated by a key to raise the same. and

" perm t the counter wheels to be read, but the nature er the present 1m rovements'is such that this shutter cannot raised to expose the counter wheels until the'oscillating lever,

or the drivingshaft 22 has been given its mltlal oscillation necessary to turnv the transfer shaft 10 sufliciently to turn in all of the transfers. This result is-eifected by means of a flanged disk 70 fast upon the right hand end of the aforesaid transfer shaft 10.- Thi'sfianged disk is in proximity toithe aforesaid lock-operated arm 53, which arm carriesa pin 71 whichprojects into the 75 center portion of .said flan ed disk and by reason of the flange norma ly revents thelock arm 53 from being raise to lift the shutter to. expose the counter wheels when the operating lever and the shaft 10 are in normal position, but as soon as the lever has been oscillated to its other or half stroke position and the pinion 23 and shaft 10 have thereby been turned their nine-tenths of a complete revolution, the flanged disk 70 is also thereby turned through nme-tenths of a revolution and thus an' openin 73 in said flange is brought opposite the pin 71 so that now the arm 53 may freely be raised by the turnin of the-key 60, and thus the shutter may a so be raised to expose the counter wheels. Such a half stroke however of the operating lever-and the nine-tenths revolution'of the shaft 10 has turned in all of the transfers and therefore if there were any transfers tripped but remaining not turned in, this device effectually prevents the proprietor from inadvertently taking an erroneous reading from the counter wheels, for 1 he cannot operate the key to raise the shutf8 until he has thrown the operatinglever to its halfstroke position and thereby turned in all of he transfers which might have been left over from the previous transaction. When the flanged. disk 7 0 has been turned in this manner to permit the raising of the arm 53, the pin 71 rests between the walls of the aforesaid opening 73 and consequently the flange 7 0 cannot lee-restored tonormal position until the shutter is again dropped to concealing position,-that is, the operator can'- not restore the main operating lever to. home position until the shutter has been, dropped by the reverse rotation of the key inits lock to carrythearm 53 and pin 71 into normal lower position.

. ile the forms of mechanism here shown and described are admirably adapted to fulfil the objects primarily stated, it is to be understood that I do not care to confine my-'.

self to any one form of embodiment of the invention here disclosed, for it is susceptible of embodiment in various forms all coming within the scope ofthe. claims which follow. Having thus described'my invention what I-claim is:
