WALTER RICHARD RoNnAM, or'onicieo, immerse, A

, To all whom (it may concern.'
Be it known that I, WALTER RionARD BONHAM, a citizen of the United States, re-
siding at Chicago, county of Cook, and State of Illinois, have invented certain new-and useful Improvements in Calculating.-A Machines, of which the following is a full, clear,
and exactfspecication.
This invention relatesv to improvements` in calculating machines, in which is employed a lgirality of dis interposed between the indicatordisks i for transmitting theL motion o'one of the l carrier or Camiers and its prima. simple an eiicient means for ilp reventin Vthe ybeyon the position to whichV it is positively moved one of the indicator members. 2
indicator disks to the other, and the resent improvements have more special re erence.
to means forcontrflinglthe rotation of the t object to provide an improved,
carrier from moving accident b Witha view to thev attainment of these v ends and the accom lishmentV of' certain other objects which the invention onsistsin the features of 301'a1ms.... j, In the said drawingsjFipe 1 is a -plan i view ofmy improved mac 'of the top plate broken away.

the outer circle of back plate, 4,. are aperture, 7', through both the inner' an outer circle of numerals on the back late may be seen in pairs successively as t e indicatordisk is rotated, the two circles of numerals on the back plate being. arranged reversely of each other, or in other words, reading respectively counterclockwise and clockwise. These 3, are thus situated onthe back plate, 4, atv proper distance apart and arranged between 'of these but -it t. the

'v
- obvious that should the carrier, 8,- continue to :rotate afterI thetooth 12 leaves it, itv
will be about to engage with the stop 13 se that when the tooth 12 lets go the stop 13 will control and prevent further rotation of the carrier. 'lhe lateral movement for thus bringing the carrier disk 8 into engagement with the stop 1 3 is preferably produced by an incline, 17, formed on the back plate, 4, in the line of movement of the tooth 12 and which causes the tooth 12 and its indicator disk 1, 2 or 3 to lift or move laterally with relation to the back plate, andthe tooth 12 'being under the edge of disk 8 at that. time it also lifts the disk 8,' As soon as the tooth v12 passes the incline, 17, thereby permitting disk 8 to drop back into lace, another tooth, 10, on the disk 8 1falls Just at the end of a stop 18 formed on the back plate in the line of movement of the tooth 10, said stop, 18, being heveled on one side to facilitate the passage of the tooth, 10,v thereover. 'Ihis prevents any retrograde movement of the disk 8.after it is released by the tooth 12,v
while the sto 13 prevents it from rotating forwardly un er the impulse it receives from the tooth 12.
A Having thus described mv invention, what I lclaim as new therein and desire to secure by Letters Patent, is: I 1.1 In a calculating machine the combination of a plurality of rotary indicators, a carrier independent of and disposed between the indicators, said carrier being adapted to en-v gage' one of the indicators for imparting the movement of anothei ol?l said indicators to the iirst indicator, means on said other indi.-
vca'tor lfor engaging the carrier whereby the lsaid movement of the last said indicator is imparted to the carrier, stop means for resisting movement of the carrier.
2. In a calculating machine the combination of a plurality of rotary indicators, a carrier for imparting the movement of one of said indicatorsl to the other, a stop normally out of the plane of movement of the carrier, and means for moving the carrier into the plane of the stop as the carrier rotates.
3. In a calculating machine the combination of a pl'urality of rotary indicators, a carrier for imparting movement of one of said indicators to the other, said carrier being free to rotate in one plane, means for forcing the carrier into another plane as it rotates and means for preventing its rotation in said other lane.
4. n a' calculating machine the combination of a plurality of rotary indicators, a carrier for imparting the movement of one of said` indicators to the other free to rotate in one plane in one direction but not .reversely, means for forcing 'the carrier into another plane as it rotates, and means'for preventing 1ts rotation in said other plane.
5. In a calculating machine the combination of a plurality of rotar-y indicator disks, a rotary carrier disposed between the disks for transmitting the motion of one of said disks to the other, a stop for limiting the rotation ofthe carrier, means on one of said indicators for directly engaging and rotating said carrier into engagement with the stop, and means on another of said indicators engaged by the carrier for receiving the rotation of carrier.
6. In a calculatin machine the combination of aplurality o? rotary indicators movable laterally or axially, teeth projecting from sa'id indicator, inclines with which said teeth engage for moving the indicators laterally, rotary carriers for imparting' the movement of one of said indicators to the other, and. under which said teeth enga e, said carriers being axially movable, cross ars on said carriers, sto s arranged in the line of movement of said crossbars but normally out of the plane thereof and adapted to be engaged by said crossbars when the carriers are moved axially towards them v 7. In a calculating machine the combination of a plurality of rotary indicators, a carrier'consisting of a rotary disk for imparting the movement of one of said indicators to the xother, teeth projecting laterally from the soy be engaged thereby when said disk moves means serving to prevent aretrograde movelaterally. ment of th'e carrier in the lst said planev of plane of movementl thereof but adapted to i plane of the stop as the carrier rotates, said 10 l 8. In a calculating machine, the combinaits movement.
7 tion Of a' Of rotary indicators, a C811'- rier for imparting the movement of one of said indicators to the other, a stop normally Witnesses; y
