Application filed November 17 1908. Serial No. 463,028.

in at Cochranton, in the count of Craw ford and State of Pennsylvania, have invented certain new and useful Improvements in Adding and Listing Machines, of which the following is a specification.

The object of the present invention is to prevent the obtaining of wrong results in the operation of adding and listing machines such as might come about through manipulation of the controlling keys and operation of the machine with the printing platen out of position to receive an imprint. It is obvious that if a machine of this character has produced a list of items or accumulator, and then with the platen out of printing position an amount is set up on the keyboarc and the machine operated, the total" exhibited by or contained in the accnmulatonwill be greater than the actual total of the printed list of amounts. Furthermore, if after printing a list of amounts and adding the same the total key of the machine is depressed and the machine operated with the platen out of printing posi-- tion, the accumulator may be cleared or left at ner'o while no record of the total is preserved. 4

The present invention provides means whereby neither addition of amounts in the counter or accumulator nor the printing-of amounts can take place while the platen 'is out of printing position and also means whereby the'total key'or keys cannot be. operated so long as the platen remains out of printing position and in the latter connection provision ismade whereby the platen cannot be moved out of printing position with the total key operated.

With these and incidental objects in View the invention consists in certain novel features of construction and combinations of parts the essential elements whereof are recited in the appended claims and a preferred form of embodiment of which is illustrated in the accompanying drawings and described'in detail hereinafter.

Of said drawings, Figure 1 represents a left side elevation-partially in section-of part of an adding machine of the wellknown Burroughs type, with the present invention applied thereto; and'Fig. 2 is a sectionalized right side elevation of the same machine.

The invention is preferably shown as adapted to said Burroughs type of machine, though it is not to be understood as limited in this regard but may be adapted to other types of adding and listing machines. It will be unnecessary to enter into a detailed description of the, Burroughs machine, since its general construction and mode of operation is well understood,-the machine being in extensive use and illustrated and described in various prior patents, see, e. 2, William S. Burroughs Patents Nos. 504:,963 and 505,078, issued September 12, 1893. However, some of the familiar parts of such machine will be specifically mentioned hereinafter as they have more especially to do with the operations of the present invention.

Referring first to Fig. 1, reference numeral 291 designates the usual depressible amount keys which-operate upon bell cranks 217, the'latter engaging slides or slide strips 214 which, when first pushed rearwardly by depression of amount keys, are temporarily held back by pivoted detents 228. These keys, as usual, measure the excursions of racks 910 which operate the adding pinions 916. The accumulator, composed of said pinions and suitably inscribed wheels, is controlled in the usual manner so that in add ing operations the racks 91 turn said pinions and wheels forward when said re cks are restored to normal position.

The numeral 265 designates the usual total key which through the customary connections reverses the order of engagement and disengagement between the racks and the pinions, so as to cause the latter to be turned backward to zero position as the racks descend.

The numeral 265 designates the subtotal key which operates upon the same connec tions as the total key but with a modified ef-' fect, so that the pinions, after being turned to zero, will be again advanced to the total.

In Fig. 1 the numeral 9.09 designates the left side piece of a restoring bail mounted upon across-shaft 207, normally retracted by a spring 208 and operating as usual to preserve roller platen 17'. Said frame rocks from a position in which said platen may receive imprints from the type 618 to apositionwhere the work can be examined when the-I platen is removed from printing position,

as indicated by dotted lines in Fig. 2.

In Fig. 2 the reference numeral 209 designates the right side piece of the before-- mentioned ball, which side piece has as usual. a depending arm carrying a roller 209 co-- operating with a wipe plate 623 in the usual manner to effectan automatic release and restoration of depressed amount keys at the.

conclusion of an adding operation'of the machine. Said 'Wipe plate is pivotally mounted on a three-armed lever 622 impelled in one direction by a spring 688 implied to the wipe plate and rocked in the opposite direction by the full stroke sector 311. In carrying out the present invention in the form of embodiment here shown, there is secured to the rock shaft 207 of the aforesaid bail a rearw-ardly projecting arm 10 with a roller 11 at its end overlying an arm 12 loose on a cross shaft 503. Loosely mounted on the rock shaft 207 is a generally sector-shaped plate 13 having a branch carrying a roller 14 which underlies said arm 12. The rearend of the plate 13 is slotted in the arc of a circle to embrace the journal 16 of the usual feed rollers 16 on which the platen 17 rests when in printing position. The said plate is normally held by its own weight to a lowered position, such as illustrated in full lines in Fig. 2, leaving the aforesaid bail to vibrate in the usual manner for automatically releasing and restoring the keys or effecting this result through depression of the usual correction key 265. It will-be obvious, however, that an upward swinging of said plate will cause its roller 14 to move, the arm 12 upward and consequently rock the bail forward by reason of the action of said arm 12 upon the roller 11. The throwing back of the platen frame carrying the platen out of printing position has the effect of swinging said plate upward and producing theabove described result, which not only releases and restores any depressed amount keys, but also holds the bail forward, preventing depression of any amountkeys. To this end the said plate 13 has an upwardly and rearwardly curved arm 19 which carries a partly spherical roller 20 in position to be acted upon by an inclined and beveled strip 21 which is secured to a crossbar 21 of the rock frame 15*. With the said rock frame forward and the platen in printing position, said inclined and beveled strip lies below and away from said roller 20 as shown in full lines in Fig. 2. But when the frame is thrown upward and backward said strip, acting upon said roller, elevates theplate 13 to the dotted line position illustrated in Fig. 2, thereby swinging the key .releasing and restoring bail forward .as also be no depression of amount keys and conse-- quently no adding of amounts upon the counter and no operationof t'hetypes fo amount printing.

The total key 265 as usual surmounts a bell crank lever 227 and the latter is. connected by a link 146 with a crank arm secured to a shaft 146*. The subtotal key is likewise mountedv upon a bell crank lever 227* and through the medium of a link 227 and a stud 227 on the lever 227 operates the latter. Thus depression .of either the total or sub total key rocks the shaft 146*, as will be obvious from an inspection of Fig. 1 of the drawings. Near its right hand end said ,shaft 146*, Fig. 2, carries an arm 23 with a laterally projecting stud 24 at its upper end. A bell crank lever 25 is'mounted under the right hand portion of the keyboard with one arm projecting forward and its extremity normally standing just above and to the rear of said stud 24. The other arm of said bell crank extends downward and is pivotally connected to a link 226 which extends rearwardly and is pivotally connected to the right side piece of the key-releasing and restoring bail, said ling being slotted at an intermediate point for engagement with the correction key lever. It will be seen, therefore, that the rocking of the bail such as produced by throwing back the platen carrier or frame draws the link 226 rearward, bringing the front end of the forwardly extending arm of the bell crank 25 behind the stud 24, thus locking both the total and subtotal keys against depression. Furthermore, with the roller platen in printing position depression of the total or subtotal key carries the stud 24 beneath said forwardly extending arm of the bell crank 25 and thus by locking the bail against forward movement prevents the platen from being thrown back. It follows that the machine cannot be operated to take a total or subtotal with the platen out of printing position.

Inasmuch as depression of the total or subtotal key locks thekey releasing and restoring bail, means are provided for preventing the spring movement of the lever 622 when either of said keys has been operated or otherwise wipe plate 623 would be unable to pass the roller 209 when moving in the upward direction and the machine would be put out of commission. To this end there is secured to the shaft 146 an arm 26 with a downwardly and rearwardly turned upper end adapted to cooperate with a stud 27 pro i tthe printing and totaling mechanism as an eeaeio jecting from the forwardly extending arm of the lever 622. Thus when either the total or subtotal key is operated the extremity of said arm 26 is brought down on top of the said stud 27 and blocks movement of the lever 622 which would otherwise take place under the influence of the spring 688.

The correction key 265 operates in the usual way to rock the bail except when the subtotal or total key has been depressed, in which case the correction key is locked out by reason of the fact that the link 226 cannot be thrust rearward. Furthermore, when the correction key has been depressed neither the subtotal nor the total key can be depressed because said link has been thrust rearward and the bell crank 25 brought down behind the stud 24. I

It will now be seen that the above described construction is thoroughly capable of fulfilling the objects primarily stated but at the same time it is to be understood that the invention is capable of embodiment otherwise than as here shown and described, though I do not claim broadly the idea of eliminating addition by the throwing back of the paper carriage.
