To .Z whom, it 11m/y concern..-

lie it known that I, RALPH P. THOMPSON, a citizen of the United States, residing at Springfield, in the county of Clark and State ing objects and mechanism to carry them into practical eiect: y

First.` To prevent any .key or keys from be ing operated while any other-key is in indicating position-that is, iu the position which it occupies while the amount corresponding with it is ina state of exhibition-which I re- 2 5 gard as necessary to the most perfect organization of (machine, and to effect. the/positive return of any key from indicating position to normal position as a preparatory step to resetting the machine to condition to allow of 3o the nextsrl-lf2 .device accessible to the hand.

First a. A key-cover to exclude access to a depressed key vto prevent such keyy from .bef 35 ing: partially manipulated when a succeeding sale is matie, which partial manipulation nihrhtrcsult in again'exhibiting the same purchase-card, yet without causing .the registering mechanism to operate, and thus re- 4o suiting in exhibiting such. subsequent sale without registering it. This is to protect the proprietor against dishonest employees.

Second. .fin arrangement of parvis, keys, registeringY mechanism, and a stop-bar ,by 4 5 which the pawls are made to act to Suspend and hold the keys in operated position.I

Third. A cancel-card which becomes 'dis-g played at or about the time said cover. starts lo open und remains so displayed until the ',"v cover again closes, during which interval of .display the indicator last exhibited is withheingregistered, andy to control. these two operations by a lever or operating drawn and the indicator for the amountnext'. sold becomes-exhibited, so that Lf a dishonest employee should do anything to keep the keycover partially open for any fraudulent pur- 55 pose he might conceive the cancel-card'would still remain displayed and the indicatorshowing the amount just registered be hidden from the view ofthe purchaser, thus at'once showing that the employee had been guilty of some 6o fraud ulent act.

. Fourth. A presser-bar and its intermediate mechanism to depress any elevated key with its indicator when the machine is manipulated for a subsequent sale, so that the last 65 previous indicator shall be automatically depressed by the very act of operating the machine into position for access to another key for a subsequent' sale, whereby as one of the results of this provision a dishonest employee 7o., would be prevented from thepossibilityof maintaining a key down and-'an indicator up while registering vanother amount, which, if permitted, would enable him` to exhibit in such second registry a 'smaller 'sum than the 75 amount then received, but which with the amount already standing exhibited would be equal to the amount then received, so that if a dollar was standing exhibited and a sale was made for one dollarand twenty-tive cents 8o he could satisfy a purchaser4 that he had reg' istered one dollar andtwenty-Iive cents `by .simply registering twenty-five cents, which when read in connection with the one dollar already exhibited would be equal'to the'one 85 dollar and twenty-five cents received, and certain other minor devices and objects, all of which will be hereinafter more fully described, and particularly pointed out in the claims'. y 9o .In the accompanying drawings, in which like reference letters and figures indicate corresponding parts, Figure 1 represents a vertical sectional view of the casing of the ma- .chine,'taken on the line a; m of Fig. 3 and 95 showing in side elevation the preferred form of mechanism; Fig. 2, a detail perspective :view of the bell which sounds when the machine is operated and of the immediate mechanism for actuating the beil-elapper; Fig. 3, loq a plan view of the mechanism illustrated in Fig'. l with the casing broken away in the .upper BEST AVAlLABLE COP portion? facilitate illustration Fig. e eva-tion of theface ofthe cancel card 'er .plate andthe indicators; Fig. 5, a sectional,

fore the-operator can get access ,to the key ol. such indicator forthe purpose'of a false in anipulation to -make it serve the purpose of in- 13o dicating a second but unregistered sale. .To

these rods Usare attached lcrersX, one at each side of themachi'ne, mom. n,den 'a crossshaft Y, carridby theszframze` (SeeFigs.

i and 3.)- .One of these levers has an extension Z, which is operated in the manner presently described. The cover D, before referred to, is, supported on studs D', monntedin the frameG, and to one of these studs is secured a' camplateE', having a handle F', which serves as n handle to thecover D. rlfhis cam-plate has -a slot -G concentric to its center of movement and a branched slot H', forminga camsurface proper to depress the front end of the extension Z of the lever X, a stud and anti-7 friction-roller I' projecting -from the extension Z in to the slot H'. Accordingly it will' be seen that by moving the 'handle F' away from an operator standing in front of themachine jthe, cam-plate E', through its; slot or'- race, H', wil'l elevate' the cancel-'cards W, through the rods U' and levers X and extension Z. When the vstud I' reaches the slot G',

elevated. Keeping this set of things in mind',

'n attention is next directed tothe series of keys J', there being one foreach lai-gel register-wheel H, said keys being hung-upon -a cross-shaft K', also supported in, the frame These keys at the rear ends each c'o'nnects with. a rod L', guided in the upperpart ,of the frame G, and each rod carries an indicater M', bearing a figure or iigurescorre respectively. These keys further each' carries a pawl O', pivoted thereto at P', each pawl at its upper end engaging with one of the wheels H, as shown. rlhe pawls-O' each have afprojection Q", to ywhich is attached a spiral springR', which in tnrnconnects at" the lower end with an arresting-pawlS', of .which there is one for each wheel H, engag- -ing therewith and mountedon a cross-shaft T', also supported by the main frame G.' A further provision of each actuating-pawl O't is the head U', which when the pawl 0' is? lifted by the actuation of the key passes be-` 11i-nd the stop-hamm be hereinafter described,

and becomes thereby held absolutely against the possibility of escaping from Vits toothed engagement with its wheel H. Thus when a key has been elevated at its rear end and the amount of Ithe purchase exhibited and the sum registered thekey remains suspended l and the indicator exhibited by reason of the key being held up by its pawl O', which hangs upon its toothed engagement with its wheel and cannot be disengaged until the stop-bar is removed from contact with its head U'.

and extends This stop-bar is shown at V' across the entire row of pawls O'and yis supported upon arms which are p'lvoted on studs W', projecting from the posts X' ofthe frame One of y'these studs further carries an acmating-arm Y', whose lug Z' fits against the under sideof one ofthe stop-bar arms. The arresting-pearls S' act to prevent a return movement of4 the largewheels when en- BEST AVAILABLE COF" appear.- f

As shown in Fig. 1 and also in Figs.f7 and 8,1the engagemen actuating pawls O' wheels is by means of laterallyprojecting llugs or teeth upon the upper ends of the 'pawls. These lateral projections upon saidpawls are immediately behind and in line with the arresting-pawls S', so that if the up- 'per end of any oneof the 'a tuating-pawls O'. is pulled forward todisengage the pawl from `its registering-wheel the lateral projection upon such pawl will contact with the arrest- Ithe effect is merely to-hold the cancel-cards spending with the ligure or snm on' the keys,

. In the form first described the cover D,the handle F', and the cam E' are connected rigidly together. In this form the handle and door are not connected directly together, the cover being pivoted at 1S to a portion of the frame andactuated by a pitman '19, having au antifriction-rollerl), fitting a slot 21,'wilh a branch 22 vin the cam-'plate 1B. vA spring 23, connected to the cover and suitably secured to the frame, acts to assist in returning the cover to closed position.

' The handle 24 is piv'oted at 25 to the frame and is connected by a pitman 2li to the campiate 16, while the plate itself is mounted upon a'pivot 27 supported by the mainframe. Thus it will be understood that when the handle is operated motion is transmitted to the cam-plate and that the latter will move from the position shown in full lines in Fig. 7 to the'positionshown in dotted linesin that figure, by taking hold of the handle 24 and moving it from the full-lineI position to the dotted-line4 position. ln this full-line` position the cancel-cards are .shown as elevated, the assumption being that they have been left in that position or the machine ius'ed to such position. Consequently in suc'r, full line position the stud I has passed from the branch H' of the slot G'. As yet the cover` D is closed. Now by moving the handle 24 from this full-line position to the dotted-line position in Fig. 7 the stud 1 will continue to `remain in the slot G', and-hence to hold up the-cancel-cards, and the pitman- 19 will have been lifted by the branched slot 22'from out of the notch 2S in the main frame and forced forward to the dotted position, thereby opening'the cover -fully from the closed position designated from' a' to b" to the position designated by c' to d'. In this" position the parts are all in the relation indicated bythe dotted lines in Fig. 7. Thus the keys are exposed above'the upper corner c of the nowopen cover- Lc The operator willthen depress the desired key-to middle position, (shown by dottedlines in Fig.' 8,) which will elevate the corresponding indicator and at the Sametime actuate the register' mechanism through the i pawl O'. As this operation takes place the foot 8 of the key manipulated wll pass over thecorrespondinn' supporting-pand and be held 1'1pby i t.'l 'lhenext thing to do is to lowerthecancelcards so as to lexpose the indicator thus elevated. This is done by moving the handle 2l from the dotted position' shown in Fig.' 7 to the position shown in Fig. S, which will at the same time close the cover and set the cam-plate back to the position shown in Fig. 8. By this change ofpositiou of the camplate the stud I"4 will have been permitted lo outer the branched slot -H', a requisite of dropping the indicator-cards. This change ot'lposition of the camfplate will also have brought the pivoted trip 15 under the arm Ll, as shown in Fig. S, so as to be ready to lift the cross-bar `11, and thus throw BEST AVAILABLE coij` ofthe key which had been depressed. This latter, operation will, ofcourse, not occur until the handle 24 is again actuated in -the 7o `direction of. the arrow from the position l shown in Fig. 8, so as to open the cover and depress another key when another sale is made, all'ofwhich is, in practical effect, the operation of controlling the keys until the last-operated key is positively returned to normal position by the manipulation of the handle F or 24, as stated in the first introductory object,- which handle is thus seen to be a hand-operating device.

Referring to Fig. 9, it will be seen that one of the arms 12 of the cross-bar 11 has been extended at 29, so as to lift a pawl 30, carried at the upper end of a pivoted bar or frame 3l, whose pivot is supported by a part of the general frame. This mechanism is to actuate the bell-clapper 32, which strikes a bell 33, suitably supported under the keys. The clapper-arm is in the form of awire spring coiled about the pivo tbar 3l and resting at the end 9o 3l on the frame. Th'us when the extension 29 is elevated by the action of the trip land the arm 14 in the manner above described it will lift the pawl 30 and throw the bar'31 against an extension of the clapper-arm, and as the extension 29 escnpespast the pawl 30' the cIapper-arm rebounds and the clapper strikes the bell. This is so timed as to occur' when the indicator isd-ropped and the drawe'r permitted to open. Thedrawerishld locked in this form of the machine by a datent 35, hung at 36 to a partof the main frame and resting at the other end ou the cross-bar 11. A lug on the drawer opposes this pawl, and when the latter is raised by the cross-bar 11 the lut.r is freed and thedrawer opened by the spring.
