HERMANN ADALBERT WEINLICH, OF BERLIN, GERMANY, ASSIGNDR TO THE TABULAT- ING MACHINE COMPANY, OF ENDICOTT, NEW YORK, A CORPORATION OF NEW JERSEY Application filed March 6,

This invention concernsaccounting machines and more particularly to printlng mechanisms therefor provided for printing certain identifying, data. I v

The'main object of the present invention is to extend the field of usefulness of such printing mechanisms whereby they may be positioning of a series of type carrying members from a single controlling column, such as a series of index point positions of a controlling card.

shown for illustrative purposes in connection with an electrically controlled tabulator in which the analyzing mechanisms consist of series of brushes cooperating with individual contacts. A single row of brushes is usually provided to completely analyze each card, these brushes, of course, searching the several index point positions at differ ential times and differentially controlling the adding and printing mechanisms to enter items therein according to the differential time at which the circuit is made at the analyzing brushes.

The various groups of card columns represent different data such as items, classifi-q cation, dates, etc. and in carrying out the present invention only one column is necessary for controlling the printing of words or abbreviations of more than one character. r

The present improvements are applicable to machines operating either on stationary or moving cards and in connection with single or combinational hole systems but for the sake of illustration it has been shown tion to provide means to control the desired The present improvements have been PRINTING- MECHANISM ron ACCOUNTING MACHINES 1928. Serial No. 259,412.

as applied to a machine of the single index point type in which cards are adapted to be analyzed while in motion.

These and incidental objects which will J The particular type of printing mechanism adapted to carry out thepresent invention does notconcern the present improvemerits and any of the prior art constructions may be readily adopted. To more clearly comprehend the improvements they are shown in connection with a printing mechanism of the type embodiedin the well known Hollerith tabulating machine, as exemplified in the Lake Patent No. 1,379,268, dated May 24,1921 but such showing should be consideredillustrative rather than restrictive.

The tabulato'r is well known and is fully shown and described in the patent referred to and as is well known'when perforated cards 10 are passed through the machine oneor more counters are operatedto show' the figures, or totals of the figures represented by the perforations in said cards.

. Shafts 20 designates a shaft operable during listing operations to drive a cam 21 which in turn oscillates a lever 26 during each listing operation.

,The ends of the osclllatory lever 26 are connected by'links 29 with a cross head 30 movable over vertical rods 31 and imparts vertical movement thereto. Extending fromthe cross head 30 are arms carrying a bail 32 which extends througha plurality of slotted bars 33 equal in number to number of letters in the largest word to be printed and eachcarrying a series of ten sliding type bars '34 which carry at their ends the desired printing characters, Normally the bars 33 are drawn upward by coil springs 35 connected to them through links and lever 36 and therefore are in contact with the bail 32 and follow the upward movement of the latter imparted by lever 26 until arrested by pawls 37 operated by the magnets 38, and engaging in one of a series ofnotches 39 in the side edge of the bars 33. The spacing of the notches 39 corresponds with the spacing of the movable type 34 and the movement of 'the bars under the-influence of levers 26 is synchronous with the movement of the perforated cards throughthemachine. It will be apparent from the preferred circuit arrangement that when a perforation is encountered by a brush 15 in the tabulator,

the series of magnets 38 will be energized and the type bars are all stopped at a point in their upward travel which brings the type corresponding to such perforations 1n the printing position and holds them there until after printing.

The series of magnets 38 are preferably connected in multiple and are energized by a source of current 11 when the circuit is completed through the perforations 12 in a particular card column of the card 10.

The cross head 30 has rearwardly-extending projections 40 with rollers which work in slots in plates or lever 41 pivoted at 42 and as the cross head rises these levers, by

reason of the conformation of the slots, are

forced back, thereby swinging a bail 43 to' the left into engagement with pivoted spring actuated levers 44, forcing the same back and allowing a series of pivoted spring actuated printing levers 45 to swing away from the type bars carried by the plates or bars 33. At the limit of upward movement of the cross head 30, however, this bail 43 is turned down and slips off from the ends oflevers 44 and these being suddenly re leased are thrown by their springs forward, thus driving the printing levers forward with sufficient force and momentum to strike either a type or the blank point on a type carrier. A type thus struck, strikes the paper 46 on a roller 47 and prints thereon the proper letter.

By the means above described it will be seen that every perforation 12 in a particular card column will cause to be set at the printing POSltlOll and printed on a sheet a series of letters which make up the word to be printed, in addition to tabulating and printing the figures in the ordinary and usual way.

While a. particular number of type bars and controlling elements have been shown the number is not considered the essence of the invention and may be changed to meet certain situations. 7
