ADDING-MACHINE.

Speciflcation of Letters Patent.

Patented Feb. 28, 1911.

residing at 'Searsporu in the county ofY IValdo and State of Maine, have invented certain new and useful Improvements in Adding-Machines, of which the following Vis a specification. Y

My invention relates to addin machines, and is more particularly designe as an improveinent upon what is commonly knownV as the Burroughs adding machine, substantially as illustrated and described, for instance, in Letters Patent of the United States, Numbers504,963 and 505,078, issued to William S. Burroughs on September 12th, 1893, although, as Will be understood, my invention is not limited, in its application, to such particular type of machine, but may be embodied and incorporated in adding machines of similar character and used for similar purposes.

As is well known, an adding machine of the type to which my invention has more particular reference, and in connection with which I have chosen to illustrate and describe my invention, is adapted to print, lis-t, and add or accumulate individual items, and to total the same. In the Burroughs machine in connection with which my invention will now be described, the individual items are added or accumulated by the in achine, and the total thereof may be taken by the opcrator-in thc present instance, by simply depressing a total key or button which brings into operation the totaling and clearing mechanism, with the result that the total, as it appears on the adding wheels, is transferred to the printing mechanism, and caused, in' the-operation of the machine, to be imprinted upon the paper at the foot of the'list of individual items. In this type of machine, moreover, when a total is taken, the construction is such that the machine is at thesame time cleared -that is to say, after the total is taken or imprinted as stated, the accumllating devices or adding Wheels are set to zero'or clear position, ready to accumulate .subsequent individual items. The printing of a total, that is a grand total, always insures the clearing of the machine and puts it into condition for receiving and accumulating other individual items, and it is ther object of mv invention to indicate to the operator by a visual indicator or. signal or otherwise the fact Whether the machine is clear or not, with the result that the operator at a mere glance, may be advised as to Whether the machine is clear and if so he may at once proceed with his Workwithout-prelimina rily going through any operation of taking a total or observing the adding Wheels. The arrangement and construction of my signal is such that if the machine has not been cleared-that is to say, if an item or an accumulation of items has been'left in the machine, the fact is at once indicated to the operator who is thus notified to clear his machine before be inning his work. In the present instance, tie visual signal is under the control of lthe clearing mechanism, ,whose operation, in clearing the machine, resets the signal to clear position, such signal remaining in non-clear or danger position so long as any amount remains in the machine, and until the clearing mechan'ism is operated.

In the drawings, Figure 1 is a plan view of an ordinary Burroughs addin machine with my signal device embodie therein; Fig 2 a sectional elevation taken just inside of the right-hand side frame of the machine; F ig.3 a detail view olthe different parts of the signal device, together with some of the old parts of a Burroughs machine, with which the new parts are directly concerned; Fig. 4 a detail View of the pin or stud on one of the movable parts of the machine for causing a r-setting of the signal device to clear A position; Fig. 5 represents a partial "'leftside elevation of the machine; and Fig.

6 is a detail of certain connections seen from the right hand side of the machine.

The Burroughs machine, in connection with which I have chosen .to illustrate and descibe my invention is so Well known, both as to construction and mode ofoperation as not to require any detailed description and moreover, as my signal device is, inthe present instance, an improvement upon or attachment to the machine and to machines of that general type, only those parts of the machine will be referred to which aregdil' directly concerned with the operation ofthe improvement or attachment.

The key-board ofthemachine has a plurality of rows of keys, 221, extendingfrom' front to rear of the machine, the nine keys in each row representing the nine di its, and the respective rows representing different epressed land kep ldenominations increasing from right to left. clearing mechanism controlled thereby, 1n

The total key orhbutton, 265, is located at the left-hand -side of the machine (Fig. 1) and is operativelylonnected with a totaling and clearing mechanism in such manner as to vpermit a total to be taken and the machine to .be cleared Whenever the total button is t depressed throughout ull operation o the operating handle or lever. This operatinglever, 36T, is arranged at the right-hand side of the machine and actuatesthe main shaft, 3.00, from which the power is transferred or communicated tothe various Working parts of the machine.

Whenever any one of the keys in any row is depressed or set by the operator, the sliding bar, 214, corresponding with that row (there being one of these bars or plates for each row of keys) is moved rca rwardly, that is to't-he right in Fig. 2 and away from the operator as he standsv at the front of the machine, with the. result that the front hookshaped end, 214'", of the operated bar will Contact with, and rock the retainer, 415, thereby releasing its lower end from locking engagement with' the notch in its rack, 210, Figs. 2 and 3), so that such rack will be free to fall, in the operation ot' the machine,

av distance corresponding in value with the particular key depressed.

The de ressing of any key and the consequent slit ing of the corresponding bar, 214, as above stated, also shifts rearwardly, a bail comprising a. pair of rocking arms, 424, one ateach side of the machine and connected together by a transverse universal rod, 402%, which is arranged adjacent to the forward ends'of all of the sliding bars, 214, and arranged to be rocked rearwardly, that is' to the rieht in Fig. 2 by the movement ot' any one o? the bars, 214, In the present instance, as usual in the Burroughs machine, cach sliding bar has a depending lug, 2Mb, which,l when such bar is slid tothe right in the setting of any key corresponding to its row of keys, engages the universal rod, 402%, and rocks it to the rifrht. This bail constitutes the means for locking the clearing mechanism, as is well known to those familiar with the Burroughs machine, it being understood that whenever any key or keys are set on the key-board, the movement is at once communicated to the bail whose arm, 424,

on the lefbhand side of the machine is brought in Josition to interfere with the depression o the total button or key and the consequent operation or' the totaling and clearing mechanism. i' Y Another part of the ordinary4 Burroughs machine concerned in thev operation of my attachment is the lever or arm, 1411, adapted to lock thc total button in depressed or operative position after the initialmovement of the operating handle and serving to hold that button and consequently the` main slm.ft,300,of the machinawhich shaft has its inner bearin f in the triangular plate,

310 and together with the parallel arm, 312,

also mounted on` the main shaft, (Fig. 4)

arrangz-a'l to transmit motion to the movable parts ot the machine through the pitman connection, 366, in the usual and well known manner. The said rock shaft 1400 carries an upstai'idingr arm 1410 (see F ig.

G) at its left-hand end connected by a link 1416 with the depending arm of the usual bell crank lever 22711 which is secured to thc -lefthand end of a transverse rock shaft 204, see Fig. 5) and on which the total button 265 is mounted. Said bell, crank lever as usual has a slot-and-pin connection with a link 911, the latter `being connected with the usual pitman 914 Vfor regulating the periods ot engagement between the pinions9l6 of the accumulator and the actuating racks 610. Said pitman is connected at its rear end with one arm of a three armed lever 913 carrying

studs

961 and 961"l arranged to be alternately operated upon by a wipe pawl or plate 821. The latter is-pivotally mounted upon the upper end of an oscillating arm or lever 813 whose movements accompany that o1 the operating handle of the machine except that the direction of movement is reversed, The forward end of the pitman is branched Vfor engagement with studs 95S and 95S on one side plate 9101i of the rocking frame in which the accumulator is carried. Normally the upperbranch o1 the pitman engages withthe npper stud 958, so that reciprocations of the itman will move the accumulator pinions rst-out of and then into engagement with the operating rack 610. W hen the total key 265 isde- Dressed this upper branch of the pitman is disengaged from the stud 958 so that during the forward stroke of the operating handle the accumulator pinions remain m mesh with the racks. W'he'n the handleis moved rearwardly with saidkey still depressed the lower branch of the pitmanV acts against the stud 958 and the accumulator inions are carried out of engagement with t eir actuating racks in the usual and well known manner. If a subtotal is desired the total key is released before the operating handle starts on its rearward journey, with the resultl that no action of the pitman against the stud 958'l takes place and the accumulator pinions remain'in mesh with their actuating racks. The latter are as usual carried npon the forward' ends of the levers 6.11 independently journaled upon a central cross shaft 600 and carrying at their rear ends sets of type (31S as shown in Fig. 2.

The. numeral` (S1-l designates the usual restoring frame or bail which extends under all of the levers 611 and whose retreat, aceompanyingrr the forward stroke of the operat-ing handle, permits the levers to drop. In itemizingr operations they drop distances determined by stops set by depressions of amount keys in the customary way. lVhen taking a total of course there is no depression of amount keys. T he extent of movement of the racks is then determined hy stops which limit backward rotation of the accumulator pinions to positions where zeros show through the accumulator sight openings. lt' has been hereinbetore described that individual rack latches 415 are displaced by rearward movement of the slidingr bars 21.4 which the amount keys actuate. When a total is to be taken all the latches are simultaneously displaced by a universal rod 299 carried by links 216, the latter being-connected with the arm 29.7K and the bell crank 2271i respectively.

The parts above described are those which are usual and well known in the ordinary Burroughs machine and mv invention, which is associated or concerned with lauch parts more particularly, will now be explained.

As hereinhet'ore stated, the purpose ot' my invention to provide a visual signal to indicate the fact whether or not the machine is clear and as such signal is under the control ot' the clearing mechanism, l utilize. in the operation of my signal. the movement of the parts above described. as operated or brought into operation by the total button, as well as the parte operated in the setting of the keys or air,l one of them. In thc present instant-e, the signal proper consists Vof a plate or strip` A, preferably slightly curved and held projected slightly above the top plate., '3123, of the key-l'ioard. The signal is provided on its upper t'ace in longitudinal arrangement with the letters "Clear" and adapted to coperatc with a cin-ze, B, secured to the top plate of the key-board, as seen in Figs. and 23. and provided with a series of live sight opcning'-, with the result that. when the signal is in one position, as shown in Fic'. 1, the word Clear will be exhibited through said openings, whereas when the signal i5 in another position the letters of said word will be concealed by the case and the intermediate spaces of the signal between said letters will be exposed or exhibited through such sight openings. By preference, I provide such spaces with acontrast-ing` color, such as red, to ,indicate d anger or non-clear position.` lFor convenience, T. will hereinafter designate the position'of thc signal as indicated in Fig. 1, as the clear position and the 'other position as the non-clear position.

The signal, A, is carried at the upper end of an arm, C, which extendsthrough longitudinal slots, 212* and 213", of the twoplates, :212 and 213, respectively of the key-board (Fig. 3) in order to accommodate the movenient of such signal arm. This signal arm which is pivoted or loosely mounted at`its lower ends upon the shaft, 334, is yprovided with a spring, c, whichtends, at all times,

to draw and hold the Signal arm and itsl signal to non-clear position, but suc-h action restrained, when the machine is clear by meant-t of an interference `which is under the control of, and operatedvby, any one of the keys. In the present instance, this interference consists of an irregularshaped pivoted latch, D, arranged at the right-hand side of the machine, and arranged to swing loosely upon the shaft or stud, 2532i. The rearward or 4right-hand end (Figs. 2 and 3) of this latch extends adjacent the. signal arm and is provided at such end with a notch or shoulder, d. This shoulder is adapted to' cooperate with a. small pin or stud, c1, extending laterallv and outwardly from the signal arm, with t e result that when the latch is in its normal position, as shown in full lines in Figs. 2. 'and 3. the 4signal arm is held to clear position. This latch is held to its normal position with lyieldingr pressure, as by means of the coiled spring, (Z1. The right-bruidv arm, 424, is provided with a .stud or pin, 424, toward its upper end and in such' position as to bear against the lower edge of the latch, which is dowmvardlj.' curved adjacent such pin or stud, in such manner that `the latch will,be raised whenever the bail, of which the arms, l2-l. form parts, is rocked rearwardly.

It will be understood that whenever any one ot' the keys depressed'the bail will be rocked rearwardly and the arms, 424, will be correspondingly moved, with the result that the stud, l2-l, will raise the latch, l), to the position indicated in dot-ted lines in Fig. 2l and the shoulder, d, will be lifted from engagement with the stud or pin, c. rThe interference provided at this point against the tendency of the signal arm to move forwardly is now removed, but such arm is restrained against movement at another point by another interferenceunder the direct control of the clearing mechanism, as hereinafter set forth.

`The signal arm near its lower end and above its pivotal point is provided with a rear 'ardly extending bar or arm, E, whose extreme rearward end, which is somewhat narrowed, is doubled back upon. itself so as latch D, that is, the first interference,

more to non-clear to form a substantially longitudinals'lot, e, which is open at its forward end and at its lower edge, as clearly illustrated in. Figs. i? and 3. The other end -of this slotted arm is pivotally connected with the signal arm in a suitable manner at the point, e1. This slotted bar or arinis .adapted to coperate with a movable )art of the machine, and to this end and in the present instance, I utilize themovement of the sector, 311, und its arm or plate, 312, and as indicated in Fig. 4, I extend the usual pin, 351, inwardly beyond the inner plate or arm, 312, to such position as to coperate under certain conditions, with the slotted arm, E.

The slotted arm or bar E issustained in proper position by means of a pivoted or swinging arm F, whose upper end is arranged to bear against the lower edge of the bar E and whose lower end is pivoted on the studf arranged near the inner or upper end of the usual depending locking arm M12. The arm F is held. toward a vertical position with its end pressing against the intermediate portion of the bar E with yieldingpressure, as by means of the coiled spring f1, as seen in Figs. Q and El, with the result that when the operating handle is operated in the usual manner and after the same has been drawn forward a suiiicient distance to disengage the stud or pin 351 from the slot e, the bar E will be forced upwardly out of cooperative relationshipV with any moving part of the machine, such as the studl in the present instance. This bar E, in connection with the stud 351, constitutes a second interference for restraining the sig1'1al arm C from indicating non-clear position even though the latch D which constitutes the first interference, may have been moved to non-interfering position in the setting up of an amount on the key-board of the machine. The .arrangementfof the parts is such that when the operating handle and its sector ll are in normal position, the stud or pin 351 bears against the closed end of the slot E and thereby holds the signal arm to "'elear7 position but, as is now evident from the description already given, upon the initial forward movement ot the operating handle and the consequent forward movement of the stud' 351 (to the left in Fig. -l) the signal arm, heilig no longer restrained by such second interference will position as indicated i`n dotted lines in Fig. 3', assuming that the has been moved to non-interfering position as indicated by the dotted lines in Fig. As soon as the pin'or studrll has been moved forwardly to `a suiiieient extent to clear the slot e, the constant pressure of the arm F will force4 or rock the arm or bar E upwardly, that is upwardly as to its rearward or slotted end, with the result that such bar is removed from cooperative relationship with the pin or stud 351, whereby the latter upon'its return stroke will not reenter the slot E but will take its position at or below the lower edge of that bar. Consequently', the return of the operating handle and its sector to normal position will not restore thesignal and its associated 4parts to normal or A"elear7 position, but such signal will remain in non-clear position so long au item or accmnulation of items remains in the machine.

Assuming that a number ot items have been set up in the machine and the first interference or latch l) has been operated to dotted line position, as shown in Fig. 3, and assuming also that the operating handle has operated a 'full stroke, that is forward and back again, the signal device has .shifted or oscillated in a forward direction so that the plate A. or signal proper no longer exhibits the word Clear through the sight openings in the case B, but indicates danger or "non-clair position, such as for instance, red spaces which may he formed or provided on the signal plate A between the letters ot the word Clean The operator can now observe by simply glaneingat the key-board that the machine is no longer clear."` Assuming that the operator now desires to taire a total or desires to clear the machine tor further work, after ohserving from the signal that the machine is not rlear," the operator depressi-:es the total hey 2433 and keeps it depressed during a full or complete lrolte ot the operating handle 36T. whereby the marhine is cleared und the total taken in the usual and well known manner. it lining understood moreover. that the usual extra or spacing .stroke ot the operating handle is taken before the total key is depressed. lVhen the total key is (lepre-sed and the clearing mechanism `inn-rated. .the locking arm illl. which 1s operatively connected with ille total hey in the well known manner, swung in a clockwise direction when the machine is viewed on the right-limiti side, as in li`igs. l and 3, with the result that the lng or block ifi-lil at its lower end engages with the lng 231,3 on the inner side of the sector 311, for the purpose of holding the total key and its connections depressed independently of the operator during the forward stroke ot the operating handle. inasmuch as the swinging arm F is mounted upon the locking lever 1411, the upper end of such arm F will he withdrawn from cooperative relationship with the bar E the hub of the signal arm C limiting movement of the arm l" under the impulse of the spring f1 and such bar will thereupon fall by gravity into such a position that the stud or pin 35,1 will enter' the slot E upon thc return stroke of will now exhibit or indicate"clear, as

shown in Fig, l. The first interference or latch l) will also assume4 its normal posi- -tion of interference by dropping down in place with its-shoulder against the stud c* Aof the signal arm so that such arm will be held or restrained to its normal or clear position, as indicated in dotted lines in Fig. 3. The machine is nov,1 clear and that fact is indicated bythe visual indication or signal Which is in position so as to be easily1 seenV by the operator Without any eifort upon his part.

It will be understood that after vthe signal moves to non-clear" position it remains in that position until the clearing mechanism is operated with the result that' so long as any amount'or item remains in the machine, that is so long as the machine is notclear the signal will indicate non-clear. Moreover, it will be understood that when tho machine is operated for the first item. the bar E is released from its engagement or coperative relationship with the stud or pin 351 and that during the operation of the machine for all subsequent items. such bar E is sustained in a plane above the plane of movement of the pin or stud 3.31 and remains in such sustained position so long as the locking arm l-'lll is normal. but when such locking arm is operated` as hereinbefore stated, the arm I" which served to sustain the bar E is swung or moved bodily with the locking arm and the ba r E thereby restored to cooperative relationship with the pin or stud 251. which. at the completion of the rearward movement of the handle, serves to restore the signal arm to its normal or clear position iu the manner hereinbotore explained.

It is evident from the foregoing description that my signal device positively indicates the fact whether the machine is clear or not and that such signal indicates nonclear position' so long as any item remains in the machine. Moreover. my signal device tends to show non-clear position at all times but is restrained by the two interferences hereinbefore referred to, the first interference being directly under the control of the key-mechanism and the second interference under the control directly of a. part of the machine which is operated at every stroke of the handle, while the restoration of such signal device is under the direct control of the clearing mechanism of the machine; so that the signal is restored and'can be restored only when the clearin mechamsm is operated. The signal is t icreore` essentially under the control of the clearing mechanism.
