To all whom it may concern: Be it known that I, WILLIAM LLDnNOH,

a citizen of the United Statesof America;

residing at Pelham, in the county of Wiest;

chester and State of New York, have invent ed certain new and useful Improvements in Yielding Depressor- Plates for Oonibmed Type-Writing and Adding Machines, of.

which the followingis a specification. v

This invention relatesto'combined type v writing andadding-inacliines, but more particularly to means for-simplifying the Ina-i 'nipulation of and eliminatingcertam sources of possible error in what is known as the Elliott-Fisher billing and adding machine.

Before proceeding Itoa description of the invention it maybe-ex 'lainedthatthe machine referred to incl es a platen; type- I writer equipped with adding,inechanism op erated from the numeralkeys. ,Thkeys are normally disconnected from, the adding mechanism and the.Qretractile movement "of the carriage effectsftwo important functions.

In the first place, it i'esets the carrying mechanism of the adder, iid secondly,.fit, es tablishes a cooperativejr'elation between certain parts which act upon'the forward rnovei ment of the carriage to automatically, connect the keys and adding-mechanism.

One source of error residesin the possibility of beginning the o chine before the carriage as been snfliciently retracted to properly position the key connecting mechanism. Another possibility of error has heretofore resided in a relation of the parts which has made it possible under some conditions to retracttheoarriage sufficiently to cause the proper connection of the keys with the adding mechanism without effecting a sufficient retraction. of. said carriage to properly reset the carrying mechanism of the adding devices. v a

In my co-pending application, No. 438,835 filed June 16, 1908 I have disclosed a keys and the proper resetting of the carrying devices prior to the recording andv adding of each successive number.

In the accompanying draw1ngs-Figure 1 1s a sectional view of an 'Elliott Fisher bill in, Fig. 1.

. surne during the retraction of the carriage tions shown in Fig; 4, and Fig.7 a detail perspective view of'th Z the carriage with whic -by the same reference charaot if The billing I which This'machine includes a flat platen ration of the m a-. travel longitudinally to space awriting. Mounted to travel on transversely of the platen, J'the writing,is :1 .tion of which is surmounted by letter and numeral keysri connected by draw-wires 9 todownwardlyz swinging type bars 10. The carriage moved to the right by carriage pro means.

f latter beingshown in Fig.* 2 whereby the carriage is dogged against forfspacing movement of mean a acters are printed one at a time byffliede adding machine equipped with my "invention but having portions of the structure hi'oken 'aw'ay, the positions of the parts "being those assumed during the recording and adding operation. Fig. 2 is a similar view showing the parts in the positions they assume during the retraction of the carriage preparatory to the recording and adding of the neigt number. Fig. 3 is a rear elevation of-a .portion of the machine showing the positions assumed by certain of the parts dur-- ing the forward advance of the-carriage, as Fig. :4: is a-. view similar to Fig. 3'showing the partsin the positions they asas in Fig. 2., Fig. 5. is a plan view of the mechanism with the parts in the positiens shown iniFig. 3.- Fig. dis a similar viewof the mechanism with thepartsin the posisepant'slnonnted. on .rnyf vention is concerned. Each part, wherever sho rgy invention is shown apnlij Enamisher billing machine 10f com iszt over mounted to the line's of t min 2.- to letter-space carriage 3, the upper in the form of a .casinggiP which a machine frame El is and 6, the stems 7 of which-are connected' to key levers 8 fulcrumed in the casing and iitrolled by key-operated escapeirien't-rnechanism, indicated generally. at 12: in-' F ig. II

As usual in this class of machines,-.the' char-I pression of the keys, and thejoarfi'ifi-bdvances step-by stepjulide'l the com let on ,escapement as the keys rise. p ,T/ze computing mechanicm.--This mocha? .nism includesia computing device or register 13. adjustable longitudinally of a guide ban li y the; purpose being toallow the arm 35 to swing freely in an upward direction, butto depress the arm when forced down-u ward. At its front or left hand end, viewed from the rear of the typewriter, the arm is provided with a laterally disposed cam 37 adapted to coact with What is termed the key connecting plate 38 ofthe register. The plate 38 is merely ledge extending across the front of, the register at its bottom, as shown in Figs. 1 and 3, and acts, upon the advanceof the carriage, to depress the key Connecting arm to the positionshown in Figs. 1, 3 and That is to say, as the carriage advances in the direction of letter spacing, the cam37 of the arm 35 will en-.- gage the end of the plate 38 and being inclined, and adapted to yield, said arm will be depressed sufficiently to allow the cam 37 on the end of the arm to ride undery'the plate. lVhen the arm 35 is thus depressed it in turn depresses the arm 32 which de presses the rear end of the lever 31, causing the front end of said lever to be elevated, This movement of the lever 31 will cause it to engage the roller abutment 29 and phus swing the yoke operating le --2 f purpose of throwing the several links 24 into: engagement with the numeral=-key stems. Thus when the hey connect a n 35 andthe plate 38 bear the relation lndn cated in Fig. 3, the carriage will be ad vancing in the direction of letter s, acin with the keysconnected to the addinbimech anism, as shown in Fig. 1, and with tlie printing point of the typewriter located I within the adding field; When the master means 16 has moved beyond the-register" and the printing point has advanced hee yond the adding field, the cam 37' willfliave passed beyond the end of the plate 38 and will be sufficiently elevated by the spring 33 to effect the disconnectionof the keys and the restoration of-the key connecting arm 35.to normal position. If now, the car'- riage is retracted,;the cam37 will ride backv over the plate 38,- as shown in Figs. 3,4 and 6, since, as has been explained, the arm 35 will ride back over the may yield upwardly independently of the arm32.. 7; i V

The letter space, Zach-ll; will be seen that during the retraction" of the carriage the cam 3'? of the key connecting arm 35 plate 38 and that during this manipulation of the machine the, keysare disconnected and can only be re connected by retractingthe carriage sufiiciently to cause the cam 37 to drop down from the end of the plate and in position to be depressed'bysaid plate upon the forward advance of the carriage, If, however, the operator retracts the carriage to a new writing position without retracting it sufficiently tocause the cam 37 to clear the plate 38, he may proceed with the writing of a number in the column to be computed while the keys remain disconnected because during this premature forward movement of the carriage the key conneting arm will be resting upon the upper side of the plate 38. To render this impossible, I provide the upper side of the plate 38 with ratchet teeth 39 arranged to dog the cam 37, and hence the carriage, against forwarder letter space movement in the event of insufficient retraction of the carriage to cause the cam 37 todrop into proper position for the automatic connection of the keys and adding mechanism. By reference to Fig. 3, for instance, wherein they parts are shown in the positions they assume during the retraction of the carriage, it will be seen that the lower edge of the cam engages the teeth and arm 35 a pawl and ratchet mechanism which acts during a predetermined portion of the retractile movement of the carriage to prevent a forward or letter space movement of the carriage until the retractile movement of the latter has been completed sufliciently to insure the proper operation. of the automatic key connecting mechanism. a It will also be observed that as soon as the'properqretractile movement of the carriage has beeninsured the locking mechanism becomes neiiective and permits the forward advance 01" the carria e, which is necessary for the properflepeiration of the machine. This provision for effecting a letter space lockof tbe cai'riage is fully disclosed in my co pendingapplication hereinbefore identified; l f-The yteldingdcpressorplate for the tartand the reach/dag means for tlirifiqdi'rydcoieea--ltwrl1 be recalledthat one of the enumerated sources of error'has resided in the possibility of retracting the carr age sufieiently to position the parts for the auto- ;matic connection of the keys before the resetting mechanism for the carrying devices wasoperated, thus allowing the printing of anism in onset condition. This obviously resulted in error because the values accumulated upon the wheels would not be carried to the wheels of next higher order and in fact certain of the number wheels would be inoperative because locked by an unset or previously operated carryingdevice; Here 'tofore, however, it has been considered impossible to so arrange the re settingmechanism that the carrying devices would be reset at a sufliciently early stage in the retraction to avoid the difliculty mentioned, 12

.a number and the operation of a number wheel of the register with the carrying meehbut by a rearrangement of parts which it is now in order to describe, I am enabled to nsure the resetting of the carrying mechanism by the retractile movement of the carriage before the key connecting mechanism 1 will be in proper position to carry or transfer a- 'value to the proper wheel. The two gyositions of a given vibrator. will be noted is positioned for proper operation. In order that thisre-arrangement may be clearly understood, it" is first necessary to explain.

briefly the construction of the registering mechanism employed in .this class I of to rotate a series of registering wheels 41 r which display the digits before a sight opening 42 in the register casing. Associated with the wheels are carrying levers 43 having swinging carrying dogs 44 which extend over the teeth of the wheels 40, as

shown in Fig. 1. The carrying levers 43 are normally held elevated by selectors 45, as shown in Fig. 2, and when released are thrown down from the position shown in Fig. '2 to that shown in Fig. 1 by carrying meters or springs 46. The selectors 45 are thrown back vby'lugs on the wheels 40 in a manner which wi-llbe clearly those skilled in the art.

To insure the engagement of the carrying understood by dogs 44with the wheels, a series of dog vibrators 47 are mounted in the casing and have their front ends extended beyond the same to facilitate their engagement by what is known as a vibrator depressing plate 48.

Ordinarily this plate-is rigidlygnounted on the carriage 3 of the typewriter and as the carriage advances to the right to present the master wheel 16 to successive'number wheels 40, the plate 48 depresses the front ends of the vibrators 47 successively and causes them to throw the carrying dogs 44 into engagement with the wheels'40. The depressor plate is of. sufficient length to hold each operatedvibrator in; its advanced position as the master wheel continues its movement across the register so that any carrying de-' vice. tofthe leftof. the wheel being operated and 2.

comparing these elements in Figs. 1

' It is obvious the carrying devices may be operated during a traverse off the register bythe master f means, or, in other words, during the printing and addingof a given number, it-is necessary to restorethese'carrying devices to normal or set position before the value of the nelgt number is thrown into the register. For this: purpose it is'usual to employ a reset rocker 4i) geared to afrocker' operating slide 50 and rocked the inwardor rearthati' since certain or ally-of eeaeea ward movement of said slide from the position shown in Fig. 1 to that shown in Fig. 2 to efi'ect the elevationor resetting of the levers 43 and selectors 45. The slide. 50 is extended beyond the front of the register and is operated upon the retraction of the carriage by what is known as acarrying reset cam 51 formed at oneend' of a swinging arm 52 pivoted upon the rear wall of the carriage casing and retained in normal position by a spring 53. Thecam 50 is,so constructed that it rides under the projecting end of the slide 50 during the forward or letter space movement ofthe carriage, as indicated in Fig. 3, and therefore 1n no way afi'ects the resetting mechanism.- When the carriage is retracted, on the contrary, the reset cam 51 engages the front end of the slide 50 and urges the same rearwardly, as shown in Fig. 6, thus effecting the resetting of the carrying mechanism in the manner described. I

The elements which have been described under the last heading are all old, but, as heretofore stated, the depressor plate 48 has been rigidly mounted. This rigid mounting of the depressor plate has made it necessary to so locatethe depressor plate48 and the reset cam 51 relative to eachother that the cam would not come into action until after the depressor plate had been removed from engagement with the vibrators 47. The necessity for this relation arose from the fact that as long as the depressor plate 48 remained "1D. engagement with the vibrators 47 it held the latter in their operative positions and therefore held the carrying dogs 44 in enga ement with the wheels 40. Therefore, i with the parts in these positions, the slide 50 shouldbe operated to reset the carrying mechanism, the frictional engagement of the dogs 44 with the wheels would obstruct the resetting operation and if suflicient force were applied to overcome this obstruction the upward movement of the dogs would tend to carry the wheels 40 backward, thus producing an erroneous registration' of- -the value previously accumulated in theregister. This necessity for,

mounting the-cam 51 s suificient distance frcm'the depressor'plate to insure the complete removal-"of the plate from the vibrators before the cam came into action was responsible fo'r the possible failure to reset the carrying mechanism by the time the key connecting mechanism was properly positioned; I

' It is the primary object of the present in-" vention therefore to devise an arrangement whereby the depressor plate will be effective to perform its normalfunction of operating the dog vibrators 47 during the advance of the carriage without necessitating a sulfil-cient retraction of the carriage to remove thedepressor plate from the vibrators before the cam 51 can act to reset the carryof the carrying reset cam 51, the depressor plate 48, and the key connecting arm 35, whereby the proper resetting of the carrying mechanism will necessarily be completed-by the time the key connecting arm 35 has reached the end of the plate 38 and drops into position to accomplish the automatic connection of the keys with the addmg mechanism. To accomplish this end it is simply necessary to so mount the depressor plate 48 that it will be held rigidly while advancing across the vibrators 47 and will be allowed to yield upwardly while in engagement with the vibrators during the retraction of the carriage, this yielding of the depressor plate permitting the carrying reset cam to be moved farther to the right (viewed from the back of the carriage) so that it may act to reset the carrying mechanism before the depressor plate has moved beyond the vibrators, since the upward yielding of the plate will pre'ventthe latter from obstructing suchmovement of the -vi* brators asis occasioned by the resetting operation. To effect these ends the depressor plate 48 instead of being rigidly mounted on the carriage 3, is provided with forwardly extending arms 54 retained at their front ends by screws 55 secured to the top of the carriage casing. The screws 55, however, are not screwed down tight,- but on the contrary, allowlimitedvertical play of the arms, the openings in which are of suiticientsize to allow somewhat greater play of the depressor plate proper. This vertical yielding or play of the plate 48 will be understoodby a comparison of Figs. 3 and 4. In Fig. 3 the plate occupies its depressed position, since it is shown'in the act of depressing the vibrators 47, while. in Fig. 4 the plate 48 is shown elevated so as not to interfere with the elevation of the front ends of the vibrators which is incidental to the resetting of the carrying mechanism. It should be understood, however, that the particular manner of mounting the plate 48 to secure the necessary vhrtical play is immaterial, as the same may obviously be hinged or arranged to have a vertical sliding motion. I

In order to hold the late 48 rigidly in its depressed position, uring its forward or operative movement, the/arm 32 of the key connecting mechanism is provided with V a draw rod 56 pivotally at its lower end to the arm 52 resided abovethe plate 48 with an angu erg-end or leg 57 through which is passed. an abutment} screw 8 disposed directly over the plate 48. ltjormally, that is to say, "when the keys are (l isconnected, the abutment screw 58 w1ll be elevated above the plate 48 sufficiently to allow the latter to rise freely, Fig. 4.

connecting mechanism to be depressed by the plate 38 to in turn depress the arm 32, the latter will draw down the draw rod 56 and thus cause the abutment screw 58 to hold the depressor plate 48 in its depressed position.- Therefore, as the plate 48 moves across the front ends of the vibrators 47, it will operate thelatter in the usual manner to insure the proper engagement of the carrying dogs 44 with the wheels 40. As soon, however, the cam 37 moves beyond the plate 38 the arms 35 and 32 will be elevated by the spring 83 and the abutment screw will be elevated to permit the up ward yielding of the plate 48. It now, the carriage 1s retracted, the cam 37 will ride over the plate 38 and while the depressor plate 48 is still located over the vibrators, thereset cam 51 will act, as shown in Figs. 2, 3. and 6, to reset the carrying mechanism. y

It will be observed that in my present arrangement the cam 51 is so positioned relative to the plate 48 and the arm 35 that it will act to set the carrying mechanism while the plate 48 is arranged over the vibrators (the vertical yielding of the plate permittin the resetting operation at this time) an before the arm 35 has dropped into position to ,efiect the automatic connection of the keys.- Thus'the enumerated possibilities of error are completely eliminated, first, be-

cause by reason of the letter space lock, to-

wit the ratchet connection between the arm 35 and the plate 38, the carriage cannot move to'the right after its partial retraction across the register until it. is sutliciently retracted to insure the automatic connection of the keys, and second,- because the relative positions of the resetting cam 51 and the key connecting arm 35,. (made possible by the yielding of the depressor plate during retraction) insures the resetting of the carrying mechanism by the time the key connecting mechanism is properly positioned and before the letter space lock' becomes ineffective. In this connection attention may be directed to the fact that the letter space look not only prevents the forward advance "advantages accrue from the yielding mounting of the depressor plate and the rc-posi-- tioning of the reset can: 51 to cause the latter to act with certainty before the hey connecting mechanism is restored to normal position, since this relation of the parts, re-- gardless of the presence or absence of the let-- ter space lock, renders it impossible to cause the connection of the keys While the carrying mechanism still remains in unset condition.

It is thought that from the foregoin the "21), construction, operation and advantages of my invention w ill be clearly apparent, but.

I wish to be understood as reserving the right to eifect such changes, modifications or variations of the illustrated structure as I A may come fairly wltlun the scope of the pro- I .mernbers, carrying dogs, and dogvibrators,
