CALCULATING-MACHINE To all whom it may concern: f

Be it known that I, EMORY S. ENSIGN, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Qalculating- Machines, Of which the following a 'specincation, reference being had therein to the accompanying draw- My invention relates to certain improvements which may be applicable to manykinds of calcula ng mathe machine having a swinging rotatable meter shown in my United States Letters 'Patent Number 773,632, issuedNovember 1st 1904, and numbered 809,047, issued January 2nd, 1906. l

Said improvements relate particularly to stop motion devices to prevent over-rotation in which each indicator wheel of the meter is adapted to be unlocked as that indicator wheel reaches the. teeth of its series of actuating disks and remains unlocked until the last tooth which would operate it has been passed when it is arrested and automatically locked during its period of rest and while the other indicator wheels of the meter are passing the teeth of their respective disks but are. adapted tobe unlocked when necessary to be operated by thecarrying device and again instantly relocked.

A further object of the invention is the providing of a simple, cheap and effective carrying device particularly designed to be used in a machine built along the lines of the aforementioned patents.

The invention consists in the combination of ele Jnents and in certain parts of novel construction entailed in the combination ofsaid elements to obtain the desired result.

A full understanding ofmy invention can best be given by a detailed description of a preferred construction embodying the various features'of my invention,

and such adescription will now be given in connecrying device in its uppermost position just after it has carried iorward the indicator wheel one movement and showing the indicator wheel as locked. Fig. 2 is a side 'elevation ofthe same with the carrying device at nearly its lowest position. 3 is a plan view of the parts shown in Fig. '1. Fig. 4 is a side view of the pawl shown in dotted lines in Fig. 2. Fig. 4 is a plan Specification of Letters Patent. Application filed September 22, 1905. Serial No. 279.380.

Fig. 12 is a side view-of part of the carrying device. Fig. 13 is a plan view of same. Figs. 14 to 27 are detail views of some of the other parts. Fig. 28 is a front elevation of my machine with the front portion of the casing removed.

Latitude is allowed herein as to details, as they may be changed or varied at will without departing from the spirit of my invention and the same yet remain intact and be protected.

Corresponding and like parts are referred to in'the following description and indicated in all of the views of the drawings by the same reference characters.

In the drawings, the numeral 30 (see Fig. 5) repre sents the base of the calculating machine upon which the side walls and cover portions are supported and from the forward portion of which extends the upward curved front cover portion 31 which supports the secondary cover 32 for partly protectingthe shanks of the primary keys 38 and which extend partly ,reatward forming a seat for the glass lid 34 pivoted to the rear cover portion 33.

Within the casing are several series of disks 38, the series shown in Fig. 5 being the tenths disks or next to the last series met by the meter during its revolution around the inner peripheries of the disks, each series comprising nine disks having from one to nine teeth 37 respectively, each disk 38 being thrown by a finger lever 38 from its normal position into Operable position to be met by the teeth 49 of the epicycle meter 41 as it is carried around the inner periphery of ing shaft 44. Each series of disks are held between side plates 35 as shown in Fig. 5.

In the drawing I have shown the indicator 36, the lever 39 for releasing the disks, the resetting lever 40 to instantly reset the meter 41 and indicator 36 back to their initial positions, after the same have been operated, all of which have been shown and explained in my prior patents. Extending outward from the driving shaft 44 are arms 43 in which is mounted the shaft 42 carrying the meter 41. Attached to the left side of each plate 35, of each series of disks 38 is a throw bar 45 attached by screws or rivets through the holes 46; this throw bar having the same radius as the disks and is cut away at its lower view of the same. Fig. 5 is a side elevation from the Fig. 7 is a rear elevation of the same. Fig. 8 is a leit portion as at 47 for throwing out the throw pin 64, releas;

ing the respectiveindicator wheel 41 to bemet by" that series of teeth 37, so that the teeth 37 will cause the wheel to revolve according to the number of-teeth upon the disk thrown out, only one disk of each series being thrown outat a time. The throw bar 45 is also pro} vided near its upper inner'part with. the finger-48 to again throw in the lever pin 64 through the slot ,48 so that the wheel will intsan tly becomelockcd after the wheel has passed the last tooth and over-rotation of the meter prevented.

its studpin 61 which passes downward through the.

.' nally upward ,-as clearly shown in' Fig. 23, having at its Extending across between the arms 43 andfcarried by'them just below; the meter 41 is the plz ttiorm' 43 upon which is supp onted plates by screws extending through the screw holes 57 58, (see Fig. 11) and from whichplateextends upward at right anglesto it the plate '51 having a forward extending arm 52 carrying a hub 53. Extending inward from the arm 52 is the stop pin 56 to limit the forward movement of the carrying lever 73. The'p1ate51- is also provided with an opening through which extendsthe shaft42 of the meter so that a plate 51. is between each wheel of the. 5 meter. The plate 5115 also provided with a smaller opening 54 for receivin'g the screw stud 101.

Supported on the hub 53 is a-hub 60 held in place by opening 59 of thehub 53 and its lower portion extendingthroughtthe opening in the hub 68 of the, lever G9'to, which hub it is made fast so that movement of the swinging arm 62 to the right willswingto the right the lever 69 or vice versa, as hereinafter stated. The hub 80 carries a swinging armor lever 62 extending diagoouter enda-hub 63 in which is held a lever or throw'pin 84 extending above the Y hub 63 'and also "extending below the huh as at 66. The swinging arm .62 has also atits upper end a plate or detent 65 attached to or made integral with ityas shown in Figs.'.3, 24 and 25 and for the purposes hereinafter stated. The swinging arm 62,

which normally holds its meter wheel 41'againBt forwardfrot ation by. its plate 65,'is adapted, when the.

ineterfll is'revolved' around the inner eripheries of the disks by the driving shaft 44, to swing to the right byth e throw pin 64 coming in'con'tact with the throw bar 45 thus unlocking the wheel and allowing it to re-' volve on its shaft 42 The lever 69'is also adapted to be moved to the right by the plate 1032s hereinafter in extreme upwardpositio'n'by a spring 76 attached to'the stud pin of the carrying lever 73 and supported a by the screw 77-inser'tedinto'the lower plate 50. The

stud pin 750i the oarryiuglever 73 extends quite a distance to die ri ht, ee 13, sqtliat the carryi'ng lever 73 is operated by'the cainl109 on its respective'right hand wheel of the meter/so that as this wheel isrefi volve'd from l eft'to right as its ,teeth 49 come in contact with 'i'ts=i'espective disks teeth the carrying lever 73 is gradually forced backward and downward by the (ram 109 until it has reached its extreme down ward and backward position, as will be understood by examining Figs. 1,. 2 and '8 at which time the stud. 75

stud is then forced up the portion *110 by the carrying lever 73 being carried upward bythe force of the spring 76'at whichtime the carrying lever 73 carries forwarda distance of one tenth of its circumference the wheel 41 on its left, it beingrememhered that the upward v movement of the carrying lever 73 is towards the operator when the meter is in its normal position. This has reached. the outermost position of the cam and the I carrying lever 73 is cut away, as shown in Fig. 12,. so as not to "come in contact with the shaft 42 or the plate 103 durlng'a ny portion of its movement and-is provided with the two studs78and 92, with a circular opening 93 on-itsjorward part; 73 and has an elongated recess it is also'provided with' the hub 79 made-integral'. with it havingthe openings8l through which is inserted a pin securing the lever 84 through the opening'83 provided in the hub 82.- This lever 84 is also provided with the projection 86 carrying a pin 85. The lever 84 is normally held against a tooth 49 of its corresponding againstthe head of the'projection 86, but the lever 84 is prevented from passing clear through the opening 80 of the carrying lever 73 and against. the side'of the wheel 41 by the pin coming in contactwith the sideoi the lever 73, but it will be seen by examiningFig. 3 that the free end of this lever 84'i's'obliged to extend quite a distance towards jthe left beyond the portion 73 in order .to meet theprojecting portion of the tooth 49 of the :wheel 41, see Fig. 1, by ajspring87 secured atone end to the carrying lever 73 and having its iree end pressing meter 4] It willbe readily seenthat the backward movement ofth'e carrying lever 73 by the. riding of the stud pin 75 over the surface of'the cam' 109,d0es not affect the wheel 41-as the lever 84 is merely for'cedbackward against its spring 87 by the forward moveinentjof the wheel. As the carrying device pushes the wheel around from the position in 'to the position In Fig. 1, the tooth'49 is brought against the plate 65 of the swinging arm 62 which acts as a stop to prevent over-rotation. -"Kt the same tilne the forward part 73 of the carrying lever 73 strikes against the stop pin 56 instantly stopping the forward movement of the carrying lever 73'.

On the forward portion 73 oi the carrying lever 73 is alever 88 pivoted on a stud 111 extendingthrough' its opening 89 .andintothe opening 930i the carrying lever and there is also pivoted on theouter portion of this stud. 111 and against the lever 88 a hub 98 having a pin' 100 made as shown in Figs. 21- and 22 and normally held in contact againstthe raised portion 96 0f the lever 88-by a spring 94 attached at one end to its head 95 and at the other .endto the stud 90 at the opposite outer end 'of the lever 88; Also attached to this stud 90 is a: spring 91,attached'at its other end to the stud 92 of, the carrying lever 73 so1tha't the lever 88 its 'upper end 96 normally held in its uppermost positionwhilethe opposite end which carries the stud son normallyheld downward against the stud 78 extending outward from theearrying lever-7 3. The end of the lever'88 having theraised' portion 96 is also inclined or beve led away as at 97 so as to easily and quickly throw out the swinging arm 62 when the carrying levermoves forward. by force of its spring 76 as the stud pin 2. 5 goes upthein'clinellll of the cm .109 and the lever 84 carries forward one position the wheel 41 and this swinging arm is thrown out only a short time, that is while the lower portion 66 is passing up the incline 97 and over the raised portion 96 when it is immediately throtn into locking position to meet the tooth 49 and prevent over-rotation, so that the wheel 41 can only be moved one place on each full movement of the carrying lever 73 moved by the earn 109 on its next adjoining wheel 41. It is also readily seen that as the carrying lever 73 is moved backward that the downward extending portion of the swinging arm 62 comes in contact with the pin 100 and the pin is forced forward and against the force of its spring 94, the pin pushing the head 96 of the lever 88 forward against the force of its spring 91 which spring carries backward the lever 88 and the pin 100 as soon as-the swinging arm has cleared the head 96. The pin 100 has a wider face (see Fig. 22) than the raised portion 96 of the lever 88 (see Fig. 18) and is wider than the swinging movement of the outer end of the arm 62 so that when the carrying lever 73 is moving backward step by step (having ten distinct backward movements corresponding to the,

ten movements of the Wheel 41 carrying the cam 109 that operates it) and reaches the point when the lower portion 66 of the throw pin 64 strikes against the pin 100 and presses this pin 100 and the lever 88 forward against the force of the spring 91, that even though the wheel 41 has by movement of the driving shaft 44 reached its series of toothed disks, and its swinging arm 62 has been moved to the right by the throw bar- --45 acting upon the throw pin 64 the portion 66 will still be pressing the pin 100 forward. This is necessary, because if the pin 64 had been pushed by the throw bar 45 to the right, while the carrying lever was at this place, and then thrown in by coming in contact with the finger 48', the portion 66 might strike upon the head of the portion 96 remaining there so that the detent would not reach the tooth 49 and prevent overrotation.

The shaft 42 is cut away as at 102 to receive the pawl 105 attached to the wheel by a screw passing through its opening 106 and into the wheel and normally held in a downward position-by a spring 107 and this pawl 105 is adapted to fall into the slot 102 of the meter shaft 42 so that its respectivawheel 41 will be carried backward to its initial position when the lever 40, shown in-Fig. 5 and explained in my previous patent, is operated.

Between every plate 51 and the wheel 41' to its right upon the shaft 42 is the plate 103 having a cut away portion 108 with beveled edges 104 slanting inward to the opening towards said plate 5], which opening is adapted to receive the pawl 69, which has its sides inclined or curved as shown in Fig. 16 so that this plate 103, which is turned by the shaft 42 will slide the lever 09 up onto it thus throwing the lever (59 to the right against its spring 71 and throwing the swinging arm 62 and its throw pin 04 to the right so that the teeth of he wheel 41 will be released and allowed to be turned to its initial position by the lever 40, so that all of the figures naught of the several wheels of the motor will show upon the reading line. i have also provided a spring 28, attached lo the plate 50 extending upward and adapted to I)l'i\'(lli backward rotation of the fur-tel 4 i.

nation, so that the last teeth-to be met would be the teeth of the units disks, and it is thus 'seen that the I teeth shown in 5 would be the teethj'of the tens disks. It is preferable-to have the'several series of disks follow this order so that, if the forward movement of the carrying lever 73 is slower than the movement of the meter when revolvedby its driving shaft and .rotated by its teeth 49 meshing with the teeth 37 of the disks, there will be no lost movement caused by a partial movement of the carrying lever while the wheel 41, to which a numberwas being carried by the lever, is being rotated by the teeth of the disk.

It is understood that my invention is not limited to the specific details of construction shown in the accom I panying drawings, but that said details may be varied in the practical carrying out of my invention. It is also to be understood that the combinations specifically set forth in the several claims are intended to be separately claimed without limitation to the use in connection therewith of other features and details of construction illustrated.
