' 'OF NEW YORK, N. Y., A CORPORATION OF DELAWARE AUTOMATIC IN DEXING MEANS FOR SELECTING BARS Application flled October 11, 1928. Serial No. 311,857.

The present invention relates to card perforating mechanism for record cards,- and more particularly to a control over the perforating operations to periodically and automatically prevent or permit effecting perforations as matter is being written on the typewriter. 7

One of the objects is the provision of an automatic control over the punch selecting means to cause a variable columnar punch operation for successive data entered on a keyboard controlling the set-up means of said punches.

Another object is the provision of means for automatically changing from one predetermined control to another predetermined control.

Another object is the provision of means in a combination of typewriting and perforating apparatus for automatically vary ing the control over the perforating operations.

Specifically, the object of this invention in the combination of a typewriter and perforating machine in which the functioning and non-functioning of the punch set-up means is controlled by a bar m'ovable with the carriage of the typewriter, is the provision of means for automatically indexing 30 said bar from the line spacing mechanism of the typewriter.

In the accompanying drawings,Fig. 1 rep resents a side elevation of a typewriter equipped with one form of the present invention; Fig, 2 represents a detail of the same showing the automatic control over the selecting bar in front elevation; Fig. 3 is a diagram representing any one of the key con-' trol circuits, and the carriage return control circuit; and Fig. 4 is a cross section on line 4.-4 Of Fig. 2. i

Referring to the drawings, Fig. 1 shows a typewriter of any suitable design comprising letter keys 9 and numeral keys 10 which actuate type bars (not shown) to print on paper on the usual platen 11 (Figs. 1 and which is mounted on a carriage 12 laterally movable on trackways'on the frame of the typewriter as is well understood.

The carriage return and platen feeding mechanisms are substantially the same as those shown in the U. S. Patent to Hart No. 1,567,590 granted Dec. 29, 1925.

The line space handle is indicated at 15 in Figs. 1 and 2 and the motor 14: and gear connections with the carriage'areshown in Figures 1 and 3. The motor 14 is in circuitwith a source of energy 15 (Fig. 3) and a carriage return key 16.

When the line space handle 13 is employed toreturn the carriageit is rotated counterclockwise (Fig. 2 and through a link connection 17 with a ell crank 18 connected by a link 19 to the line spacing pawl 20 carried by an arm 21 pivoted on the platen shaft, it moves the pawl 20 clockwise (Fig. 1) which through its cooperation with a ratchet 22 on the platen shaft, line spaces theplaten.

This line spacing is effected as an incident to the return of'the carriage by the motor by a bell crank comprising a lower arm 23 actuated during the initial carriage return movement as shown in the patent referred to, and also comprising an upper arm 24 hearing on a depending portion 25 ofa bar 26 guided at one end on a pin and connected at its other end to the pivot connectin the link 19 to the bell crank 18. This mec anism is substantially the same as that shown in the l a single row of setting-up devices mounted on a traveling carriage to effect a set-up in said set-up devices row after row. The setting-up devices are operated when the keys are actuated, through the instrumentality of electric circuits and. Bowden wires.

For the purpose of illustrating this invention, it is considered sufficient to illustrate (Fig. 3) a movable die plate 27, a punch v guide plate 28 movable with the die plate and 108 stop that the bell cranks 37 are mounted on a traveling carriage of which the guide plate is 9. art.

e bell crank 37 is actuated by a Bowden wire 38 (Fig. 3) which in turn is actuated by a solenoid 39 in circuit with the source of energy and a switch 40 controlled by a typewriter numeral key and another switch 41 controlled by a control bar 42 (Figs. 1, 2, 3 and -4) rotatably mounted on and longitudinallv shiftable with the typewriter carriage. The bar 42 has high places to close the switch 41 topermit the circuit to be completed by closing of the switch upon operation of a typewriter numeral key as matter is typewritten. When the circuit of any key is completed, its corresponding solenoid is energized and the appropriate set-up is effected. The traveling setting-up carriage is caused to escape to the next column by means shown in the patent.

In the use of the combined typewriter and punch, it is desirable in certain systems of business to record only certain of the typewritten information by perforations in the card in the perforating machine. For this reason the control bar 42 is provided with 4 low portions which will permit the switch 41 to open when they are under the switch and prevent completion of the set-up circuit by the typewriter key.

It is necessary in certain businesses to punch different information for successive typewritten lines of information. For this reason the control bar is provided with a plurality of sides, six in the present instance, which may be provided with different arrangements of high and low places to suit the special requirements of the system in which the machine is to be used. The writing of a line and the punching of a card record of some or all of the matter written in it are done in a single operation of the composite machine, i. e. the operation by which the line is produced. K

The mechanism described so far has been disclosed in a previously filed application of W. W. Lasker et :11 Serial No. 136,075, filed Sept. 17, 1926, for an automatic selecting bar, in which the control bar 42 is rotated manually for indexing purposes. The mechanism common to this and said application is claimed in said application.

The invention herein disclosed consists of means for, automatically rotating the control bar 42 after each line has been typewritten.

For this purpose the rotation is preferably effected by means actuated by the line spacing mechanism. This means consists of a ratchet wheel 43 (Figs. 1, 2 and 4) secured on the control bar 42 and actuated by a pawl 44 mounted on a pitman 45 connected to the pivot connecting the line spacing pawl 20 to the arm 21. It is seen then that the con-- cally or manually brought into functioning position or the automatic means may be thrown off or on at intervals as desired.

As is well known the line spacing mechanism of t pewriters may be controlled for single an double line spacing as desired. The design of the automatic indexing device is shown to function during double line spacing. It is obvious that the invention is not limited in its use to a double line space adjustment and that a control over the pawl 20 may be supplied to permit it to be moved far enough to permit indexing of the bar for single'as well as for double line spacing.

What I claim as new and desire to secure by Letters Patent, is:

1. In a composite machine comprising a card-punching machine and a typewriting or like machine connected to control the punching machine, the combination of a device for making and breaking the connection between the two machines according to a program, and shifting means operated automatically by the controlling machine to change from one program to another.
