UNITED STATES PATENT OFFICE CLAIR D. LAKE, F ENDICOTT, NEW YORK, ASSIGNOR T0 THE TABULATING MACHYNE COMPANY, OF ENDICOTT, NEW YORK, A. CORPORATION 0F NEW JERSEY DETACHABLE .RECORD CARD Application filed February 24, 1927. Serial No. 170,469.
This invention relates to perforated cards and the like and more particularly to a record having a detachable stub which when detached from the record card will leave a clean,
smooth, vertical edge on the latter so that it may be fed through the well known Hollerith sorting and tabulating machines for accounting purposes.
, The invention applies to any record or card which is removably attached to either a stub or a holding portion of the same material as itself in such a waylthat the card may be readily torn away from the holding portion. An example of such a construction is the usual sales slips which are bound together to form fillers for sales books and in which each slip is provided with a line of perforations to permit it to be readily torn away from its binder. Another example, is the well-known inventory card which is ma-de of fairly heavy stock and which consists of a stub portion and a record portion separated by a line of perforations or scoring which permit` ready separation of the portions. The perforations usually provided consists of small round holes or slits and when the portions are torn apa-rt each has a rough or ragged edge. In many cases this is not objectlonable but if the record'in question con- 30 sists of a tabulatin card, for example, such an edge causes di culties both in stacking the cards and in their handling by a tabulato Both of the xamples mentioned have counterparts in ta ulating cards as these cards may be used either as or in connection with sales slips and bound in a liller pad or they may be used as inventory cards in which case they present obvious advantages if an attached stub is provided with each card. The present invention contemplates a detachable construction for such an arrangement in which the card when-torn away from its attached portion presents a clean straight edge.
It should be understood that the `word stub as used in the present specification and claims is to be construed broadly and is intended to cover any attached portion regardless of whether any data is entered thereon or not. The principal object of the invention is to provide a record card which is attached to a portion of the samematerial as the card in portion but which has a-conguration forms ing a weakened section oii'set from the line.
Another objectof the invention is toprovide a record card which is attached to a portion of the same material as thecard by a perforated line whose Weakest parts are offset from the delimiting line between. the kcard and the portion to which it is attached.
Another object of the invention is to provide a record card which is attached to a portion of the same material as the' card by a perforated line consisting of aseries of slits terminating in extensions projecting into the .body of the card.
Another object of the invention is to provide a record card which is attached toa portion or part of the same material as the card by a erforated line consisting of a series of slits aving angular extensions projecting into the body of the card and with the extensions on adjacent slits approaching each other to form weakened Vsections offset from the slits.
Another ob'ect is to provide arecord card having a stu associated therewith which when removed from the record card will leave a clean smooth edge. l
Various other objects and advantages of my invention will be set forth in the'following" description and drawings in which .i
showing the stub attached thereto and` disclosing same as an inventory record;
Fig. 2 is an enlarged fragmentary view showing the means for holding the card and stub together;
Fig. 3 is an enlarged fragmentary view of the record card and stub showing lthe stub' detached therefrom;
Fig. 4 is a perspective of therecord card ig. 1 is a front view of my record card taken on line 4-4 of Fig. 1 showing the clean, smooth edge after the stub has been detached therefrom.
For the purpose of illustration I have shown my record card as being applicable to an inventory system using the I-Iollerith method of accounting. When an inventory is to be taken the party in charge of each section is given a stack of record cards which are numerically numbered. Each card has attached thereto a stub bearing a number corresponding to that on the record card. As the material is being called off by an assistant, an original entry of each individual lot is made on the record card and associated stub. The stub is then detached from the card and securely fastened to the inventoried material which obviously shows that the lot has been inventoried and also that it may be easily found in the case of a recheck or the like. In other words an individual record card is made out for each inventoried lot. When the inventory has been completed the record cards are then forwarded to the auditing department Where they are key punched,the punched information being taken from the original entry on each record card. After the punching operation the record cards may then be fed through the well known Hollerith sortlng and tabulating machines.
Referrin more particularly to the drawingFig. 1 iscloses my invention as comprising a record card 1 adapted to be used in tabulating machines and a detachable stub 2. This stub is attached to the record card along a line 3. As will be noted in Fig. 2 the perforated line 3 comprises a plurality of straight clean-cut slits between the record card 1 and the associated stub 2, the cuts as shown at'4 being slightly indented into the rbody of the record card. This structure is weakest mechanically at the uncut spaces 5 extending between the adjacent ends of the indented portions 4 and this weakest portion is obviously oifset from the line 3. When the stub is detached from the card a portion of 5 as disclosed in Fig. 3 will break away from the stub 1 so that the ragged edge of the indentation is out of alignment with the clean-cut line 3. The card when removed from the stub presents true straight edges on every s1de and may be used in accountmg machines or in. other cases in which such edges are advantageous.
While I have shown and described and pomted out the fundamental novel features of the invention as applied to a single modication it will be understood that various om1ss1ons and substitutions and changes in the form and details of the device illustrated and 1n its o eration'may be made by those skllled. in t e art without departing from the sp1rit of the invention. I intend to be llmit-ed therefore only as indicated by the scope of the following claims.
What is claimed is:
1. A record card provided with a partition line extending between edges of a card comprising a plurality'of elongated slits terminating at said edges of the card and intermediate slits eXtending towards each other between said elongated slits and on the same side of the latter, and laterally thereof.
2. A record card provided with a partition line extending between two edges of a card comprising a plurality of long alined slits having short terminal portions continuous therewith and inclined towards each other on the same side of said long slits.
3. A card including a partition line for separating one portion of the card from another comprising a plurality of alined long slits and short slits continuous with said long slits of the same width as said long slits, and offset therefrom, all of said short slits extending on the same side of the long slits. l In testimony whereof I hereto affix my signature.
