The invention has'relation to calculating machines for performing problems in addition, subtraction, multiplication and division, and registering the results, and more particularly to means for cordinating the movementsto and from operative position of the registering and of the` carrying devices. The object ofthe invention is to provide improved means for this purpose.

The machine is shown as' equipped with the specific selectingy means of my co-pending application for patent Serial No. 142,190, filed January 13, 1917, of which this is a divisional application; and reference is made thereto for such parts of the complete device as are non-essential to the present combination.

The invention consists in the novel *construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, ,illustrating the invention, the numeral 2 designates the casing; 3 the numeral keys, arranged in a plurality of denominational series ;v 4 a rear transversely lshiftable carriage; 5 a series of registering wheels upon shaft 6, said shaft having bearings in said carriage; 8 a series of carrying dogs yor kpawls Vupon shaft V9; l() a series of selectingor differential actuating elements, one selectingy element' for each series of numeral keys, by which they are set up, said elements being slidable upon shafts 10; 11 a series of intermediate gear wheels upon shaft 12, said gears operating the registering wheels and being actuated by the selecting elements and also by-the. carrying dogs; and 13 is an operating device or crank handle upon shaft 14, said handle operating the selecting elements and the carrying mechanism. C l

The shafts 10 of the selecting elements are mounted in a frame 21, pivoted forwardly at 22 and adjustably supported in rear by shaft 23, said shaft carrying a cam 24, whereon bear at opposite points rollers 25 of said frame, whereby,ffor each rotation ofthe shaft the frame is raised from normal depressed position, raising the shafts 10 and the selecting elements into position to rotate the intermediate gears 11, upon sliding movement of said elements upon their shafts, the frame and the selecting elements being normally in lowered position, for reasons stated hereinafter.

The shaft of the operating handle is provided with a bevel gear connection 26 withy yto return them to normal position. The

shaft 27 has at its rear end bevel gear connection 36 with a `transverse shaft 23, the latter shaft having spur gear connection 38 with the carrying shaft 9, and turning the carrying shaft four times around for each turn of the'crank handle.

In performing addition and multiplica tion, the operating handle is turned clockwise once completely, to thereby'move the frame 21 and to move the selecting elements longitudinally upon their shafts, from normal lowered position, midway of the lengths of their strokes, te raised position, at the forward end of the strokes, then rearwardly to the opposite end of the strokes, and then to return said elements to normal position, the carrying being performed while the elements are'so returned, in the same clockwiser movement of the handle. In performing subtraction and division, the handle is turned counter-clockwise once completely, to move said frame and to move the selecting elements from normal position to raised position, at the rear end of their strokes, then forwardly to the opposite end of the strokes, and then to return the elements to normal position, the carrying being performed as stated, while the elements are so returned.

` In order that said elements shall be returnable backwardly or forwardly, as the case may be, without actuation of the intermediate gears by Ithose elements that have been axially turned, it is necessary that, after the elements have been moved longitudinally, as stated, they shall be lowered and then returned, so lowered, to normal position. And inasmuch as the selecting elements are movable either rearwardly or forwardly, according to the nature of the problem, and as the carrying is performed after the elements are so moved, it is necessary that they shall normally be located in lowered position, midway of the ends of their strokes.

The carrying shaft 9 is provided with a series of annular collars 42, each collar having guides 43 wherein works a transversely slidable dog or tooth S, the dogs of all of the collars being arranged spirally, entirely around the shaft in a single series.

Located between the intermediate gears 11 are reciproca-tory carryingmembers 47, pivoted at 4S and having each an arm 49, normally extending in the path of a transverse pin 50 of a registering wheel 5, each registering wheel having a pin 50, and said member having an oppositely projectinc` arm 51, provided with a cam surface 52, adapted to eX- tend within the path of movement of va carrying dog, there being one member i 7 for each dog and for each registering wheel. The arms 51, when thrown pivotally by the pins 50, will cause their respective dogs, as they contact therewith in the rotation` of the carrying shaft, to move endwise, into position to engage the intermediate gears 11. The dogs are returned to normal position by springs 53 thereof, and the pivoted carrying members are returned to normal position by radial projections or fingers 54 of the carrying shaft, said fingers following the dogs and having end cam surfaces engaging said members.

In order that, during the rotation of the registering wheels in setting up the problem, the carrying dogs shall not be moved endwise into effective position by those of the carrying members 47 that have been pivotally thrown by the transverse pins of the registering wheels, and shall not, in the turning of the carrying shaft, engage and turn the registering wheels, it is provided that the carrying shaft shall be movable toward and away from the registering wheels, the dogs upon said shaft being movable therewith into position for engagement with said carrying members, said dogs being thereby slid into active position and rotating the registering wheels upon the last portion only of the turn of the crank handle. For this purpose, the carrying shaft is mounted at the outer end of corresponding arms of bell-crank levers 59,V fulcrumed upon the shaft 23, the outer ends of the other arms of said levers having pivotal connection with the frame 21 at G0, whereby, as the frame is raised from normal lowered position, the lever is rocked, to rock the carrying shaft and its dogs away from the registering wheels, and as the said frame is lowered, after the registering wheels have been rotated in setting up the problem, the carrying shaft and its dogs are rocked toward the registering wheels.

Means are provided to prevent the intermediate gears 11 from overthrowing or rotating more than one tooth when carrying, consisting preferably of a series of bars 145, having at their forward ends double-beveled or V-form teeth 146, adapted to intermittently wedge between or mesh with the teeth of said gears, there being one said bar for each gear. The forward ends of the bars 145 are slidably supported upon shaft 23, forked or slotted portions 147 of said bars engaging annular guide grooves of said shaft, the rear ends of the bars engaging and sliding in perforations 148 of the bar G2. rod 149has at its ends 152 sliding bearings in elongated slots-150 of the frame brackets 151 which carry the shafts 23 and 12, said ends being flattened in order that the rod may slide freely back and fort-h'without rotation.

The rod 149 is connected to the vertical A transverse corresponding bar 145... The upper' or head ends 158 of the levers 154 normally bear upon the peripheriesy of the yannularcollars 42, each said collar having a circumferential notch 159.

In this way, as the bell-crank levers 59 are operated to rock the carrying shaft and its dogs toward the registering wheels, the levers 154 and the bars 145 are moved therewith, until the forward toothed end of all of said bars mesh with the teeth of the intermediate gears. The collars 42 being now turned, in the carrying operation, as previously eX- plaincd, the notch 159 of each collar in turn, or successively, is brought around opposite the head end of the lever 154 corresponding thereto, whereby, should any intermediate gear 11 be engaged by its pawl or finger 8, in the carrying operation, the teeth of this gear, rotating the space of one tooth, acting upon the forward bevel-tootlied end of thebar 145, will push or slide said bar rearwardly,

the corresponding lever 154 'being at the same time allowed kto be turned pivotally upon rod 149, owing to the head end of the lever moving within the notch of the collar 42, said head end, when riding upon the peripheral surface of said collar, locking the bar 145 against sliding movement, the forward end of the bar being engaged with the gear.

The rotation of the intermediate gear one tooth being completed, and the collar 42 continuing to turn, the head end of the lever is immediately pushed out of the notch 159 and the lever operated to rengage the bar 145 with the intermediate gear,y this re'e'ngagement serving as a check upon the movement of the gear, thereby preventing overthrow.
