Be a known that I, Cmms N. Menu.

. LAND, a citizen of the United States, and a resident of Dorranceton, in'the county of Luzerne and State of Pennsylvania, have invented certain new and useful Im rovements in Adding-Machines, of which t as fol lowing is a specification.-.

.My invention relates to adding machines and particularly to the well known Wales adding machine described and U. S. Patent #797032, granted August 15, 1905, in which the printing mechanism: is

-mounted at the end of the device farthest from the operator and comprises a laten on which the paper to receive the record'is supported, means for appropriately "sitioning the type atthe line of print in rent of the platen, means for prope toward the platen and an inking ribbon 1nter osed between the type and t e platen.-

Ihe'ma'chine, in some of its styles, is likewise provided with means whereby the function of the accumulating mechanism may.

temporarily be interrupted without, at the same time, suspending the function of the remaining mechanism of the machine, so that an item may be printed on the paper recording. strip on which the accumulated items are recorded without including it in the series of items accumulated or adding it into the total when these items are added. up.

In usin the machine in the manner last mentione it has been found by experience that sometimes confusion ensues between the items printed on the strips which. have been accumulated and those which have not. In order to avoid such confusion, or rather to lessen the tendency which exists to have it occur, the machine is provided wlth means whereby the items not to be totallzed'are re- I A corded in an ink of a different color'from are recorded.

that in which the other items are recorded, and briefly this is accomplished by proyld ng appropriate means for moving. the lnking ribbon frame as an incident of the de ression of. the key for-interrupting the notion of the accumulating mechanism so that there isautomatically and of necessity presented to the line of print a; strip of mkinfi ribbon rovided with a, difierent colored in from t at in which the accumulated items I have ascertained by experience in using the machine that it maybe convenient to'nse I Specification oil-otters Patent.

difieienteolored ink at the will of the operator. To that end I have provided the rib '15 I tion thereof; Fig} is a side elevation of the l same, 'andtIfig. 5 1s a plan view of the finger pieceof the supplementary key. V In the drawings, 1 is the frame of the machine onwhich arts are mounted. "These parts lnclu'de a ank of keys arranged in denominational series, each key provided the ke depressed is interposed in the paths of rac bars 20, one for each numeral wheel.

with. a stem by the de ression ofwhicha "stop corresponding to t e numeral value of These rack bars are each provided with I tooth racks'Ql on their upper edges and are supported at theirfront ends upon links 22 suitably pivoted, either in the frame of the machine, or on some convenient part thereof and at their rear ends upon the extremities of bell crank levers 23- mounted to oscillate upon a shaft 24. The other ends of these levers 23 are pivotally connected with the printing mechanism. The rack .bars 20 are adapted to mesh with pinion-s 30 with which the numeral wheels are provided. These numeral wheels display in proper order on I.

their edges (not shown) the numbers from El. through 9 to 0, and are all mounted one common shaft 32, there being one numeral wheel for each denominational series of keys.

the rack barsare moved forward the extent It Wlll readily be understood that when of their movement is governed by the posi-- tion of the key stops'above referred to, and. this movement in turn governs the extent. of rotation of the numeral wheels when they are in mesh with the racks, during the return movementvof the latter to normal position. The forward movement of the racks to any extent is governed by other stops which are actuated by the key stops.

The machine is actuated by a handle 'wnich oscillates a shaft (not shown) which,

proper one is in a position opposite the oint of print. This point of print is in a 1 ed horizontal plane opposite a shaft on which the platen 53 is mounted and which in turn is placed in a carriage 54 adapted to move laterally across the rear end of the "chine. I -At each side of the framework of the machine there are provided bell crank levers 60 pivoted at 61. One arm 62 of the lever is hinged by a stem 03 to a key 6st provided with a finger piece 65, which projects above the upper case of the machine. The other arm 66 of the same lever is provided at its lower end with a foot or hook 07 adapted to swing in under the numeral shaft 32 to support it. It is obvious that when this key 61 its stem 63 is depressed the bell crank 60 will be swung to move the hooks (37 er the ends of the shaft 32 so that when the rack bars 20 are oscillated the pinions cannot come into contact with them (see Fig. 1). In other words, the purpose of this key which is called an elimination key is to interrupt the function of the adding mechanism so that while the depression of the numeral keys will cause the registration of the corresponding numbers on the strip of paper provided for that purpose, yet so long as this key is depressed, such items will not be added by the machine.

At a convenient place on each side of the frame 1 are mounted vertical spindles 100, 101. On these are placed two ribbon spools 102 of usual construction, each provided with a central aperture 103 engaging with one of the spindles on which the spools turn and on which they are free to reciprocate vertically. Each spool 102 is provided with an upper horizontal flange 101 connected to its upper plate by a collar 105. The spools are supported in a frame consisting of a cross piece 106 provided at each extremity with a fork 116 to embrace the collar 105. Projecting outwardly from the cross piece 106 are ribbon guides 107 provided with horizontal flanges, top and bottom, 108, between which an inking ribbon 109 is adapted to move Back of the spool frame is a lifter comprising two levers 120 rigidly fixed to a cross rod 121 suitably mounted in the frame of the machine, and which rod is adapted to cooperate with the lower end of the key stem (53, so that when the key (3-1 is depressed the lever is tilted, which movement actuates the levers 120 and these. in turn lift the ribbon spools to bring the lowermost strip 119 to the point of print. This strip is of a different color from the upper part of the ribbon and is preferably saturated with red ink. It will thus be seen that when the elimination key is depressed and so long as it is held depressed the item set up by the numeral keys will be printed in red ink and, of course, will not be added into the machine.

Secured to the cross rod 121 is a second rearwardly extending lever Mounted. in a suitable aperture in the frame of the machine is a supplementary key 600 (pref erably arranged near to the key (5 1) and provided with a depending stem ($01 adapted to engage with the end of the lever 222 to depress it and provided with a retracting spring 602 surrounding the stem 601 within a casing 603 provided for that purpose, so that the key (300 will automatically be restored to its initial position after depression.

A suitable spring 223 serves to ass st the restoration of the parts to their original positions. A finger piece (301 is provided for the key 600 and is preferably divided into colored panels on its upper surface as indicated in Fig. 5.

If the operator desires to have any item, which is set up on the numeral wheels thereby transferred to the printing mechanism, recorded in an ink of a different color from that normally employed, he will depress the supplemental key 600. This in turn will actuate the lever and rest the lifter and the ribbon spools in the manner ii-evhi-usly described to bring the strip 119 to the point of print. So long as the key 000 is kept dcpressed the items thereafter recorded by the printing mechanism will continue to litl printed in the distinguishing ink. on the ribbon strip 119 until the key (300 is restored to its initial position. If, at the same time, that the key 600 kept depressed the elimination key 64. is also depressed, nothing or:- c'urs and the position of the strip 119 with reference to the point of print is not altered, because the lifter and the ribbon'spools have been already moved to place. In effect, therefore, while the actuation of the key 64 compels the printing of an item recorded but not accumulated in a distinguishing color, the actuation of the key 600 enables the operator at his operation to record any other item also in a distinguishing color.

What I claim as new is:-
