(Giimi'nn UNDER THE raovIsIoNs or THE acT or mincir a, 1921,41 STAT. L., 1313i) To @ZZfwLom t may concern: Y

Be it'known that I, CARL SoHAnLnii, citizen of the Duchy of Brunswick, l-mpire oi" (ierinany, residing at Brunswick, Germany, have invented certain new and useful Improvements in Calculating-Machines,V ci which the following is a speciiication. i

My present invention relates to calculating machines or the type in which the numbers and items to be introduced into the calculation are set up through the agency of keys, and in lwhich the result of the calculation mounted on a sliding carriage. Otherwise,

the interior construction of the machine is' quite immaterial'tor the purpose of my Y present invention and may vary widely.

It is the object of my invention to provide 'means for shifting the traveling .carriage stepwise in either directionV eachstepV corresponding to onedenoininational unit; and

tolocate suitable actuators for such shitting meansat the front of the machine.

In the accompanying drawings, I have illustratedv an embodiment oi my invention, by way ,of example, it being understood` that modificationsl may be made in the construction and disposition of parts shown without thereby involving a departure fromy the spirit and scope of my invention.

Intlie drawings, Figure l shows a niachine with this invention, .partly in side elevation, partlyrin section. Fig. 2 represents the machine viewed from the i'eai` and ypartly cut away to show the mechanism by means of which this invention is carried into effect; kITigBis` a view similar to Fig. l showing the mechanismin another stage oie operationfFig. 4 is -a view simiiai-to F ig. 2`but showing the mechanism in the stage operation represented "in Fig. 3,

. Referring to the drawings, the sliding carl' riage a which carries the computing wheels (not shown) isprovided with a spring actuated latch b which cooperates with a rack c provided on a part of the machineirame for the purpose of vlocking the carriage a in various positions. On moving the latch ZJ out of engagement with the said rackc, the carriage i is released tok be shifted by hand.

The novel means for obtainingy an automatic and stepwise shifting of the Asliding carriage a, each step corresponding in its extent to oney denominational unit, will now Y ported in the rear part ofthe machine and have extensions which teiminatef in. cani faces f, by means or" which a leverv h is swung about its pivot g whereby theupper end ot' tlielever 7i acts against a comb-edged plate ,7c oscillatingly supported on the shai 71.

Vhen thev plate /0 isvr caused'to swing igor# ward it engages the latch b'wherevei1v the same may bepositioned within its sliding path, and disengages the latch from the star- V tionary rack c; see Fig. 3.

4The comb edge plate'/c with its shaft z', is mounted in a sliding frame u, which is guided, by means oi pins fu', in slotted parts w secured to the frame of the machine, and although the latch o is now in engagement with the teeth of the platey le, the carriage a may yet be moved in conjunction with thev plate 7c. The joint movement is caused in a manner which will nowv be described.-

In accordance with which of the two keys or actuators cl and e is being depressed, the corresponding one of the two'stays Z 'and m will be -aised. Both these stays arel swingingly suspended on common yokeV 0 which is mounted on the pivot a. yThen owing to the key e being depressed, the stay m is raised, as illustrated in Fig. 4, the yoke 0v is caused to'swing to the left. `However, this swinging action of the yoke would be prevented by the second stay Z which is not set in motion by the key cl, but for the provision of special means which cause it to move away from the key Z and Ythus gain free space to descend while the associated stay'm ascends, the said means compris-y ing stationary pins g that engage slots p in the respective stays Z and m. While the yoke o swings, the stationary pins g form pivots about which the stays are compelled to rock whereby the stay that is" not rraised by the respective key, is caused to move away from its associated key.

The yoke 0 is formed with'an opening 1- through which proj ectsa pin s(v on 'the slidling frame u, and by reason of this consaidframe 'u and move the same in either direction in conjunction with the comb edged plateale and the carriage a.' The eX- 'z will then engage'the said fingerv from spring 15,'v see `Figs.V 4 and 3. Y t

To insure Ytheirrproper. return intol thev tent of the shift thus produced corresponds tothe regular distance between two denomginational units.` The V resulting unit shift pression of the key-d.

come locked thereby. The comb edged plate 1c together with its sliding vframe 4u is then free to Vbe automatically returned into the initial position by the Vaction otthe iiiedinitial position, no matter whether the shift has been tothe left or-to"thefright,a

finger m' is provided which is loosely susf I pended'roma'part of themachinc frame' and 4which coperates with two stationary stops y, y, limiting the swing of the finger in either-direction; Y, The comb plate kisy provided witha projection that engages the finger from: the left when the said platereturns underv the action of its spring 701 after havingV performed the above def.

scribed shift tothef'leiit, which. direction is indicated by the full lined arrow in Fig. 2.

When the sliding'frame u has been shiftedv to the right and the combvedged plate `7c swingsV backV under the action of the spring k1 into its rearward position, the projection the right and move the same Aagainst the left to secure, by Letters Patent ofthe UnitedY v operative position on actuation of any oi Vsaid actuat0rs,iwhereafter said carriage is f stop y. Y z Y Y What I claim as my invention and desire States, is: I
