This invention relates toprinting and perforating machines and is especially adapted for the printing of records .together with the perforating of records which are subsequently utilized for the tabulation of the various items enumerated on the printed record or may be utilized to print the record without punching or punch the record without printing.

In commercial practice it is customary to -make invoices up on a typewriter and if arate and in a separate machine.

the business institution uses record cards as a means of accounting, obviously the record cards would have to be perforatedby a sep- That is, the various items enumerated on the printed invoice would have to be punched on .the

record cards in order to be used in the wellknown Hollerith tabulating machines.

According to my invention when the invoice is printed a record card is concurrently perforated.

In a typewriter printing and perforating machine'of this kind, it often occurs that.

an operator in depressing a numeral key of the typewriter will depress it sufliciently to close a contact to the punch selecting magnet of the perforating machine but not sufiiciently to print on the record sheet. As far as I am aware, no practical means has ever been produced or even proposed which will guarantee the printing operation along witha punching operation. This means I have succeeded in producing a practical and efiicient form.

An object of my invention is to provide a typewriter printing and perforating machine wherein the 1iperforating of a record card cannot be e e sponding printing operation ispositivelyv cted unless the correeifected on the record sheet.

- certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the accompanying drawings I have shown for the purpose of illustration one form of mechanism embodying the invention in which:

Fig. 1 is a detail view of a key punch showing one of the selector magnets and Referring more particularly to Figs. 1'

and 2, a general description of the operation of my typewriter printing and perforating machine will be given. Upon the-depression of a typewriter key it is rocked about its pivotal connection and closes a contact mounted beneath the typewriter key. Mounted above the typewriter key on the frame of the typewriter is another air of contacts which are closed by means 0 a bail overlying all of the typewriter keys. These contacts are spaced at adistance above the bail sothat a mere depression of a key will not cause the bail to close them. It is only when the keys are operated with sufficient force to insure printing that the bail flies up and closes the contacts. In the operation of the machine an operator in depressing a type key will have to strike it a blow suflicient to rockthe bail in an upward direction against the contacts mounted above the keys.

As soon as the bail strikes the upper contacts they are closed and simultaneously a printed record is made upon the record sheet on the platen roll of the typewriter. When the key is depressed for a printing and punchingoperation closing the lower contacts and rocking the bail upward to close the upper contacts, a selector magnet of the perforating machine selects. a punchv corwith the key depressed. That is',

res onding ey '-2. is depressed, the punch corresponding with that key will be set up for a, perforating Operation. Immedlately after the key is released by the operator to allow it to return to its normal position, the carriage of the typewriter is moved longitudinally through the escapement mechanism. The platen carriagenecd not be shown here in all of its details, only so much as is necessary for an understanding of my invention is shown. The platen roll carrying the record sheet is rotatably mounted in a carriage which carriage is integral with a rack meshing with a gear which gear is fixed on a shaft. Also mounted on this shaft adjacent to the gear is a star wheel which rotates with the shaft when it is actuated by the rack. This star wheel is adapted to close a set of contacts which in turn estab lish a circuit to the punch actuating magnet of the perforating machine. .It is to 'be noted that if the typewriter key does not receive a blow suflicient to; rock the bail about its pivotal connection toclose the upper contacts that no printing will be made on the record sheet and also that the punching device will not function. In other words, the device must print in order that the punching magnet can be actuated to perforate a record. As the operation of the perforating machine used in connection with my device is .fully described in the copending application of J. T. Schaaif, Serial No.

731,980, filed August. 14, 1924, it is unneces-.

sary for me to present a detailed description of the entire machine.

For an understanding of the invention certain parts of the above perforating'mw' chine and their operation will now be described. Referring to Fig. 1, each selector magnet 11 is provided with an armature 2O pivoted at 21. The armature 20 is provided with a forwardly extending lever 22 overlying vertically movable plungers 24 slidably mounted in the machine. Each plunger has one leg of a bell crank 25 slidably connected thereto, the opposite ends of said bell crank being connected to separate -controlling slides which will hereinafter be called interposers and are indicated at 26. These interposers are each provided with a notch 27 in the upper parts of their for- Ward ends so as to permit the ready downward movement of the punch actuator 28 without encountering the interposer 26. When any one of the selector magnets has been energized, the armature of said magcent its lower end and against which the upper end of the spring 33 abuts.

The card 32a, as will be noted, passes between the stripper plate 32 and a die 33a fitted in the table of the punch. This die is provided with a plurality of openings 36 one for each punch which receive and pass the discs punched out of the card. These interposers 26 are each provided with a notch 37 on its under surface, which notches are aligned across the punches 30 when the interposers are in their normal retracted position shown in Fig. 1. These notches 37 are arranged to receive a ivoted common switch operating bar 38. T is bar 38 is normally held in the position shown in Fig. l by any suitable spring. Bar 35 is connected to the insulated finger of a movable switch contact element 40 by a link 41. This link has its free forward end provided with a shoulder 42 which is engaged by the forward side of the bar 38 and the link 41 is held down in a guiding slot in the bar by a spring 43. The free end of the link 41 is also provided with a hook 44 which is engaged over a laterally projecting finger 45 projecting rearwardly from the punchactuator 28. When anyone of the interposers are shifted forward so as to have its front end in the path of the actuator 28 the bar 38 will be rocked on its pivotal connection and engaging the shoulder 42 will be rocked on its pivotal connection and en aging the shoulder 42 will pull upon the link 41 and bring the movable contact element40 into engagement with the stationary contact element 39 thus closing the circuit to the magnet 45a which attracts its armature 46 and through the lever 47 rocks shaft 48- and the selected interposer, through actuator 28.

This communicates motion to punch 35 thereby driving the same through the card and die.

As the actuator 28 is rocked on its fulcrum the tongue or finger 45 is elevated and engaging the hook 44 lifts the free end of the link 41 out of engagement with the bar 38 against the tension of spring 43 and permits the spring contact 40 to draw the link 41 rearwardly. Thus the circuit of the punching magnet 45a is broken immediately after the operation of the actuator, irrespective of the length of time bar 38 may be held in its forward position as actuated by the interposers. The interposers are returned to normal inactive position by means of independent springs a connected to one tailed description of my typewriter printmg and perforating machine will be disclosed. As the general construction of a typewriter is wellknown I have, therefore, only shown schematically the mounting of some of the numeral keys to which part of my invention applies. One of the numeral keys is shown at 10 pivotally mounted at'51 and has the usual connection at '53 with the type hammer 54 adapted to print on a record sheet on the platen roll 55.

Mounted on the frame of the device at 56 directly beneath the left end of the arm 58 of the typewriter key 10 as viewedin Fig. 2 are contacts 12. Upon the depression of the key 10 the contacts 12 are closed establishing a circuit to the selecting magnet 11 of the perforating machine. Itoften occurs that an operator does, not strike the key a blow suflicient to cause the printing hammer 54 to print a record but depresses the key far enough to close the contacts 12. The result is that a record is erforated but no printed record is made 0 the item on the record sheet. I have succeeded in providing means whereby the printing of a record is positively made before the punching mag- Y net of the perforating machine is actuated to perforate a record.

To overcome the perforating of a record without printing as above referred to, I have provided contacts 13 similar to contacts 12.

' The contacts 13 are fixed to the frame of the typewriter at 57 and are mounted directly above the arm 58 of the numeral key 10 (Fig. 2). A-bail 14 fixed at its both ends to a pair of side arms 59 which arms are pivotally connected to the frame of the device at 60 is provided for closing the contacts 13. The side arms 59 are biased by a spring 61. A stop 62 is also provided for arresting the bar when it is actuated by the depression of one of the numeral keys. A set screw 63 mounted in a block 64 fixed to the machine may be provided for adjusting the contacts 13. These contacts are adjusted by the set screw so that they cannot be closed, setting up a circuit'to the selecting-magnets 11 of the perforating machine,

until the type hammer 54 has actually printed on the sheet on the platen roll 55..

In other words the key of the typewriter must receive a blow sufficient to rock the bail 14 upwardly to close thecontacts13 insuring a printed record before the selecting magnets of the perforating machine. are set up.

Assuming now that the key '10 has been struck a blow suflicient to allow the bail 14 to \.close the contacts 13 and also printing a record. During this operation the contacts 12 and 13 respectively have been closed setting up a circuit to the selecting magnets 11 (Fig. 1). Immediately after the operator releasesv the key to allow it to return to its normal position, the platen roll 55 rotatably mounted in a support or carriage 15 integral with which is a rack 16, meshing with a gear 19, will be moved longitudinally b well known escapement mechanism. The gear 19 meshing with the rack 16 is rigidly fixed on a shaft 65. Also ke ed on the shaft 65 is a star wheel 66. 'l his star wheel as will be noted is adjacent to the gear 19. The star wheel 66 closes the contacts 18 each time the laten is moved .one step longitudinally. T ese contacts are fixed to the frame of the typewriter at 67 and are mounted directly beneath the star Wheel 66 so that they may be closed when the in the record card corresponding with the printed information on the invoice. It is obvious that other means maybe employed such as a slow acting magnet -or a stick circuit for holding the upper contacts 68 closed until the contact 18 has been closed.

Referring now to Fig. 4, an illustration of the circut diagram is disclosed as comprising a plu ality of selecting magnets 11 and a plurality of contacts 12. The double contact 68 held ina downward direction by a spring 76 is provided for completing the closure of the circuit to the punching magnet 45a when the contacts 12 and 13 are closed. The magnet 45a is energized by the contacts 39, 40 when closed by the interposers 26. The energization of magnet 45a causes the perforating machine to punch. Pr'esuming that the numeral key 10 has been struck a quick blow, the corresponding contacts 12 being closed by the key, and contacts 13 by the bail 14, a circuit will be established as follows: from'the positive side of the line 70 through contacts 12, selecting magnet 11, contacts 13, wire 71,'magnet 72,

wire 72a and back to the negative side of thev line. The energization of magnet 72 closes viously described. Presuming now that the operator desires sim 1y to use the perforat- -in machine to per orate a record without printing. Upon the depression of the punch actuating key 23 of the perforating machine, a circuit is established as follows: from the positive side of the line through wire 75, lower contact 68 now held closed by a spring 76, wire 77, contacts 39, 40 closed by the interposer 26, wire 74, punch actuating memker 45a andback to the negative side of the In the normal operation of the machine I have found that by timing the contacts 13 so that they are not closed unless the type 54 engages the platen 55, the magnet 72 will maintain theup er contact 68 closed until the escapement o the carriage causes closure of contacts 18. This is so even though the contacts 13 may open and thus permit deenergization of magnet 72 before the escapement causes closure of contacts 18 by reason of the time required for the magnet 72 to release 'its armature. In this connection it is obvious that to permit a slow releasing operation of the typewriter keys the magnet 72 may be a slow acting magnet so as to hold the upper contact 68 closed an appreciable length of time after contacts 13 may haveopened. Also as I have previously stated, a stick circuit or holding circuit may be employed in connection with magnet 72, such limited therefore only as indicated by the= scope of the following claims.
