Patented Jan.. 7, 1930 'ses saresr oFFicE HEINRICH RUBER, BERLIN, GERMANY, ASSIGNR 20 THE TAB'ULATING MACEENE i COMPANY, IFNDICOTT, NEW YORK, .A @ORPQRATON OF .NEW JERSEY naine nunon .llpplcantonl filed may al,` 1928, serial No.BYSQB), and in Germany January 5w, wat.

This invention relates to punching devices7 particularly for peritorating record cards or the like.a

information is recorded on a record card by means oi indes: points, usually in the torni oi perfoiations.,,l The card is provided with a plurality of parallel vertical columns, each ord having ten or, more vertically spaced index point positions, in any one ci' which a perforaihe meaning oi the per iorations depends on the position in vvhich it is punched. Thus, if the index point positions are arranged in the order l2 ll, 0, l to 9, a perforation in the :louth index point position fm1 the t0l) .01 the @Mid Would designate the number l..

Many large'estahlishinents which maintain branch olhces-require these oiices to transmit their records to there in the torni oi'punched record cards which are tabulated .or otherwise operated'on hy accounting n1achinos in the main oiiice. llhere the branch oce has a cornpapatively small amount -oi information to punch on the record cards, it

is uneconoinical to use a key-operated pen.

i'foratinp,- machine. ln this and other cases Where little punching is done, it is desirable to use a smaller and more econonial punchingI device, simple in construction, and manu ally operative.

lt is an obj ect ci this invention to provide an improved hand punch tor peri'orting reccards'. V Another object" is to provide an'irnproved 'card holder for positioning a card properly to receive a perforation.

nStill another object is to provide means for maintaining said card holder and punching tool in adjustable cooperatingl relation.

A further object is'to provide index means on said holder for indicating the -proper adjustment of said punch With respect to the card positioned on said holder.

Various other objects and advantages' of my invention will be obvious from thefollowing particular description of one form of mechanism embodying the invention or from an inspection of the accompanying drawing;

'and/the invention also constitutes certain new and novel features of construction .and comdevice g' parts hereinafter set forth and Fig. 2 is a longitudinal section thereol2 and Fig.. 3 is a side section thereof. ln detail, the punching device comprises a card holding itraine consisting ot a plate 'l With an aperture 2 of the same shape as the lrecord cardfand designed to receive the card therein. Aattached to the bottoni of plate l is a die plate 3 on which the card isadapted to rest when positioned in aperture 2Q lllhe die plate has a plurality of holes 4l therein oi such number and arrangement that when the card aperture? each hole is directly he neath an index oint position on the card. Legs 5 are provi led to hold the punching de vice above a table he placed., Mounted on the surface ot Il is a punch carriage 6 Which is provided with lugs l yfitting1 over the longitudinal edges ci said plate to constrain said carriage to slid' ahle increment longitudinally loi* the holding trarne. 'lhe punch carriage 6 carries a slide 8 on its surface, slidable cooperation between the slide and the carriage being'provided by ribs 9 on the latter seated in slots l() ci the former. Slide 8 is provided with an upper hollovv member ll and a lower mein* loer 12 which have alined openings guiding; a punch 13 tot vertical movement therein. The punch is normally held in its uppermost position by a spring ld located Within the hollovv oi7 inemloer ll, a lug l5 on said member engaging a shoulder l@ on the punch stern to limit the upward movement ci the punch. The carriage 6 has a slot le'xtending panalu lel to the short side of aperture 2 and oi substantially the same length. Member l2 is adapted to move in said slot when the punch slide 8 is adjusted to position the punch over a' desired index point position.

Plate 1 is provided with a series of gradua` or the like on which it may Gill to indicate the index point position over which the punch is positioned. The short side of plate 1 has graduations 22 to assist in indicating the index point position under the punch. Each long side of plate 1 has depressions 23, a card column apart, with which pins 24 cooperate to yieldingly hold the punch carriage 6 in adjusted column position. Thepins 24 are carried by spring blades 25 fastened to the surface of the carriage and will automatically withdraw from depressions upon movement of the carriage. Slide 8 has fastened to its surface similar blades 26 carrying pins 27 for cooperation with depressions 28 at each side ofthe carriage 6. The

depressions 28 are spaced apart the distance y between successive index points so that upon adjustment of the slide 8 to the selected index point position, the depressions .28 will cooperate with pins 27 to yieldingly hold the slide 1n adyusted position.

Ybe perforated to designate items, comprising i a frame including a top plate having a rectangular slotcut therethrough ofthe same shape as the record card and ibottom plate attached to the top plate andl having a die portion below the slot, said dieportion being adapted to support the record card and being provided with a plurality of holes arranged in the same manner as the index point positions of the record card, and a punch device mounted on said frame for slidable movement along thelength and Width ofA said slot and adapted to coact with said die portion to perforate the card.

In testimony whereof I hereto aflix my signature.

HELN RICH .RUBER In operation, a record card is placed in aperture 2 -and the carriage moved along the plate 1 till pointer 20 is in line with the graduation 19 corresponding to the column to be punched. The carriage will be retalned in adjusted position by engagement of pins 24 n in a pair of depressions 23. The punch slide Sis then moved along carriage 6 until pointer 21 is in line with the desired index point position. The punch is then operated by pressing on handle 29. This operation may obviously be repeated in Aas many adjusted positions as desired.

pointed out the fundamental novel features of While I have shown and described andl the invention as applied to a single modiiication it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation fmay be made by those skilled in the art without departing from the spirit of the invention. I intend to be limited therefore only as indicated by the scope of the following claims.`

I claim:

A .perforator for a record card provided with a plurality of index point positions which may be perforated to designate items, comprising a frame having ahrecess therein of the same shape 'as the' record card and adapted to receive the card, the frame being also provided with a die portion'having a plurality of holes ltherein arranged in the same manner asfthe index point ositions of the record card, a carriage slida l carried by said frame, a hollow member sli ably carried by said oarriage,'l a punch guided for vertical movement inv said' member and adapted to coact with the die portion to perforate' a card and a spring within the hollow of said member for normally holding the punch in u permost position. p

2. A per orator for a record card having a plurality of index point positions which may ilo
