To all wkowrit may concern:

Be it known that I, LYNUS CLYDE REY' NoLDs, a citizen of the United' States, and residentv of Washington, in the District of Columbia, have invented certain new and useful Improvements in Machine Operating Mechanisms, of Which the following is a specification.

The present invention relates to a machine for Vpunching or performing other Work on cards or sheets of paper -or other material, for example, such as are used for recordin and tabulating ce-nsus and other compilations, and it is the primary object of the invention to provide in combination With a machine for feeding sheets or other objects and manually controlled for punching or performing other Work on the sheets, means whereby some of the Work Will be performed automatically, or without manual aid, according to a pattern or predetermined arrangement. In other Words, the machine is a combination manual and automatic one, in order that some of the punches or work performed on the sheets can 'be done according to manual Selection for the successive sheets, and inl order that the holes punched in or other Work performed on a series of successive sheets in the same manner or in repeated duplicate, Will be accomplished automatically. Thus, the machine is operable for automaticaly punching or performing otherwork o n each of the successive sheets to provide'v predetermined perforations or the like, when a series of sheets have the same data to be recorded thereon, While the rcst of the perforationsor other Work performed on the sheets are accomplished under manual vcontrol and selection, so that they Will differ on the various sheets as desired.

This machine is particularly designed for use inv punching perforations or holes in cards, although the invention can be used in machines for performing other Work on cards and sheets of various` sorts. Card punching machines are now used quite eX- tensively for tabulat'ing census and other statistical data and compilations, and the cards When punched are used 1n connection with sorting and computing machines. The sorting machines Will sort the cards according to certain holes punched therein, While the computing machines Will add up the numbers or other data recorded on the cards by the holes punched therein. It is the present practice to use tWo punching machines,

viz., a gang punch and a selective punch.

he gang punch is used for punching similar holes in a number or stack of cards, with a vieW to saving labor and time, when a series of cards all have corresponding holes or perforations, because this gang-punching will eliminate the individual punching of the cards excepting for those additional perforations or holes which vary for the successive cards. The gang-punched cards are then punched by the selective punches by manual selection according to data which varies for the different cards, and the gangpunching Will therefore save some time in the selective punching.

It has been found in practice that the gang-punching of stacks of cards is objectionable for several reasons. Not infrequently, the Work of selectively punching the cards is held up awaiting the gangpunching thereof, thereby losing time. Furthermore, in gang-punching, the punches must penetrate all of the cards in a stack Which are being gang-punched, and in order to make the gang-punching profitable, it is necessary to punch quite a number of the cards at once. This results in the perforations or holes of the intermediate cards being im# perfectly formed, and having ragged or feather edges, dueto the fact that only the lowermost card or cards are firmly supported on the die, While those above, being superposed, can yield more or less' as the cards are luider compressive strain when the punches penetrate them. Thus, some of the stock instead of being sheared from the cards by the punches with a clean cut, is pushed down by the punches to form a feather edge, and this has vcaused trouble in the sorting of the cards, because these feather edges project from the sides of the cards and interfere With the sorting.

-The purpose of this invention, in the art of card punching, is three-fold. First, it dispenses with the use of gang-punches altogether; secondly, it saves the time rcquired for gangunching by combining this operation with t c selective punching automatically and Without consuming additional time in selective punching; and third, it eliminates irregular punching or feather edges around the perfor-ations or holes, be-

cause the cards in being punched individually will have the perforations cut clean. The present machine, as used for punching cards, Vis operable manually in `the usual way for making the selective punches, while the duplicate or similar punching operations, now done by the gang-punching operation, is accomplished automatically between the intervals of hand punching. The automatic mechanism of the machine is controlled by a pattern or master-card which is previously punched so as to have such perforations as are to be repeated for a series of cards, and the machine is so constructed that when this pattern card is applied, the successive blank cards which are inserted and punched selectively under manual control,

- will be automatically punched during the intervals of manual punching, according to the perforations in the pattern card, thereby combining the present method of gangpunching and selective punching into one operation with resultant decided advantages in overcoming the objections in the prevailingpractice.

his invention is not only useful in the art of punching or perforating sheets, but is also capable of advantageous use in other arts wherein sheets or other objects are operated on by work'performing elements, some of the work being repeated for which the automatic mechanism forming the subject matter for the present invention is suited, while the remainder of the work is done selectively under manual control.

Another object is the provision of an adjustable and reversible key-board for the machine, in order that itcan be placed at different positions for the convenience of the operator, and to enable the key-board to be reversed for both right and left hand control and operation. This feature is of advantageto relieve the operator, as the continued operation of these throughout the day sometimes tires the operator, whereas if the key-board can be shifted to enable the operator to change his or her position, relief can be had. Furthermore, the reversal of the ke 7-board enables either the right or left hand to be used with equal facility.

With the foregoing and other objects in view, which will be apparent as the invention is more fully understood, the invention resides in the combination of elements as hereinafter described and claimed, it being understood that various changes can be made within the scope of what is claimed, in adopting this invention to various uses, within the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a plan view of the improved machine. v

Fig. 4 is a cross section on the line 4-1 of Fig. 2, and also showing the switch keyboard in section.

Fig. 5 is a diagrammatical view showing the electrical circuits.

As illustrated in the drawings, the invention is embodied in a card punching machine, which comprises a suitable base or frame 11 having a guide o'r slide way 12 for the card 13 to be punched omperforated, and a ratchet bar or carrier 14 is slidable longitudinally in the base l1 for feeding the card 13 longitudinally as it is operated on or punched. The carrier 14 has upturned portions 15 at its ends against which the ends of the card or sheet 13 bear, to cause said card to move with the carrier. This carrier is advanced by a spring motor device 16 or the like, and an escapement device 17 coperates with the carrier so that it is advanced step by step, but permits the carrier to be slid rearwardly quickly to start the punching operation. The base 11 has a transverse die 18 over which the card 13 moves, and a transverse row of punches or work performing members or plungers 19 are disposed above said die to,y

operate downwardly on the card. The punches or plungers 19 are slidable vertically in guides 20, the lowermost one of whichY holds the card 13 on the die 18, so that the lower ends of the punches will properly penetrate the card. -The punches or plungers are raised by the springs 21.

The foregoing construction is quite similar to the selective punching machines now used, and the punches are, arranged in a transverse row to correspond with the columns or rows of digits on the card, so that in each position or step of the card, any one of the punches can be operated for making a corresponding perforation or hole in the card.

The punches or work performing members 19 are operated or depressed by means of levers 22 fulcrumed on`a shaft 23 supported' by standards 24 rising from the baseat the opposite sides of the guide 12, and the respective levers 22 rest on the punches 19 and are raised thereby. The operating levers 22 are actuated by solenoids, `electroits core and thereby swing the corresponding lever 22 downwardly and bring ,the corresponding punch into operation, and when the solenoid is deenergized, the parts are returned by the respective spring 21. The solenoids or electro-magnetic means are used -in the present embodiment of the machine, but it will be understood that other? suitable operating means can be used.

The means for preventing more than one of the levers 22 from being operated at a time, so as to avoid two or more punches being operated simultaneously, includes a transverse row of., upstanding stops 30 below the levers 22 and between the vertical planes of oscillation ofy said levers. These stops 30 are supported for yieldingmovement transversely of lthe levers, and as shown, are supported by upstanding leaf springs 31 carried by a crossbar 32 above the guide 12. These springs31 hold the stops' 30 in position, so that any one lever 22 in being moved downwardly can pass between the two corresponding stops 30, and in doing so ,will separate said stops.- The stops in contacting with each other will be moved in opposite directions from the lever r22 that is moved, and this will prevent any of the other levers 22 being moved, but when the actuated lever 22 returns to idle position, the stops 30 also return to normal position. As shown, an arch 33 carried by the base passes over the levers 22 to limit their upward movement and to also limit the separation ofthe stops 30.

A battery 34 or other source of electrical energy is used for energizing the solenoids 26, and a conductor or leader 35 connects one pole of the 'battery with one terminal of each of the solenoids. Individual conductors or leaders 36 are connected tothe other terminals of the. solenoids and extend to their respective contacts of key-operated switches 37 for the respective solenoids. The other contacts of said switches 37l are connected by fa common conductor or leader 38 with the other poleof the battery 34. At any position of the card 13, it is an easy matter to operate the desired punch by simply closing the corresponding switch 37, which will close the circuit of the selected solenoid 26, and the corresponding punch is therefore brought into play, and as soon as the switch 37 is released, it opens the circuit and the solenoid being denergized will permit the punch and its actuating means to return to normal idle position. By using the electro-magnetic operating means under the control of key-operated switches, the least possible manual effort is necessary to operate the punches, as the Work is done eletrica-lly but under selective manual contro In order to advance the card 13 whenever one of the punches has been operated and retrieved or returned, a lever 28 is fulcrumed on the shaft 23and extends under all of the levers 22 so as to be swung when any one of the levers 22 is operated, and the lever 28 is connected by a link 29 or other .operative connection with the escapement mediately after one perforation is made. i

p Coming to the means for automatically causing the operation of the punches in cer' tain 4positions or steps of the card 13, in the embodiment as shown, the base 111 has a shelf 39 supporting a slab 40 of insulating material and provided with a depression or receptacle 41 for receiving a pattern or master-card 42 having predetermined perforations or holes 42 punched therein in certain columns or rows which are to be repeated for a series of cards 13. This' pattern card 42 is similar to the blank cards 13 and can be readily removed and replaced so that the automatic operation can lbe changed from time to time as required, or the automatic operation can be controlled by any other suitable pattern. Suitable. means may be provided for holding the pattern card 42 in place, such as longitudinal lips or flanges 43 to overhang and over-lap the edges of the card. strips 44 are embedded in the slab 40, so that the card 42 covers them, and in order that the perforations or holes 42k will expose the respective bars 44 which are arranged according to the digits or longitudi-Y Longitudinal contact bars ory nal rows of markings on the card. The bars 44 have binding slalb 40 for the connection of the conductors 36whereby to electrically connect the bars 44 with the respective solenoids or electromagnets, it being noted that the pattern card* 42 is reversed in position relatively to the card 13, in view of the arrangement of the posts 45 near one end of the parts. The pattern card 42 being of paper or similar material will insulate the bars 44 from above, excepting where exposed through the perforations or holes 42. These perforations 42 or equivalent means are for the purpose of closing the circuits v Of the respective solenoids26 at the differentv positions or steps ofthe card 13 determined by the longitudinal positions of the perforations in the pattern card. In order to close these circuits through the perforations i of the pattern card, there is provided a transverse rock shaft 46 journaled in bearings 47 carried 'by the forward portion 15 of the carrier 14, so that said shaft is mova'ble with the card 13 relatively to the pattern card 42. This shaft 46 carries a contact comb or brush constituting spring fingers 48 extending downwardly and rearwardly to drag on the pattern card 42 during the forward ste by step movement of the card 13. There 1s one of the spring fingers 48 above each Ibar 44, and the lower free ends of said fingers have the same relative position on the pattern card 42 as the punches 19 have on the card13, so that the fingers 48 serve as an indicator to enable the operator to readily observe from the card 42, the particular column of the card 13 that is under the punches. Furthermore, when the card 13 steps into a`position to bring the fingers 48 over `a column of the pattern card 42 having a perforation 42, the corresponding finger 48 will spring downwardly through said perforation and make contact with the respective bar 44, so as to close the circuit Aof the respective solenoid. The shaft 46 has a finger piece 49 arrangedv to receive the pressure of the thumb or finger for pushing the carrier 14 and card 13 which has been introduced, rearwardly to starting position, and this finger piece is so arranged that when it is pressed, it will turn the shaft 46 and raise the contact fingers 48 oli'l of the pattern card 42 during the rearward movement, thereby rendering the automatic circuit closing means inoperative during such rearward movement. A Spring 50 between the linger piece 49 and a part of the carrier 14 will turn the shaft 46 back to normal position as soon as the pressure against the nger piece 49 is relieved. Y'lhus, when the carrier 14 and card 13 to 'be punched are slid rearwardly, the lingers 48 are raised ,oi of the pattern card 42, and when the card 13 has reached its rearmost position 'to start its forward step by step movement, the fingers 48 will be returned against the pattern card 42 and brought under the desired tension thereagainst lby the pressure of Fthe spring 50.

The contact lingers 48 are connected by a common conductor or leader 51 with the conductor 38, whereby the bars 44 and their contact lingers 48 are connected in parallel with the corresponding switches'37, so that the.

circuit of any solenoid can be closed either by the corresponding switch 37 or the correspending bar 44 `and. contact finger 48 according to whether the operation is controlled manually or automatically. In order to automatically break the circuit of the solenoids when they are automatically closed,

' and thereby automatically advance the card 13 and repeat the automatic operation if called for, a suitable switch 52is disposed in the conductor 51 and means is provided for opening said normally closed switch 52 as soon as any of the punches 19 has completed its work in penetrating the card 13. As shown, the switch 52 is carried by one standard 24 and the lever 28 has an arm 53 so arranged that when the lever 28 is swung downwardly with any of the levers 22, the arm 53 `will contact with the switch 52 and open it when the punch 19 that is operated has punched the card. This will immedi-y ately open Ithe circuit of the energized solenoid, and the piinch and lever 22 will therefore be returned promptly to normal position under the infiuence of the corresponding spring 21 and the escapement pawls will therefore allow the carrier 14 and card 13 to advance a step, just the same las they do as when the switches 37 are operated for operating the punches.

The switches 37 are embodied in an adjustable and reversible key-board comprising a casing 54 having a double clamp 55 for engaging the forward wall of the base or frame 11 when said casing is inverted to either its reverseJ positions, and said clamp has a set screw 56 or other suitable means for fastening it to the base. This clamping means permits the casing 54 to be loosened and shifted longitudinally Ialong the base to any desired position for the convenience of the operator, or the casing 54 can be turned upside down for reversing the keys 58. The switches comprise companion contact springs 57 separated from one another and two sets of push buttons 58 are slidable through the opposite top and bottom walls of the casing and are arranged on opposite sides of the companion contactsprings 57 whereby the push buttons or keys 58 on either side can be manipulated for moving the correspond-` ing springs 57 against the opposite ones, thus rendering the -key-board reversible. VVllen Vone set of keys is uppermost, the same is suited for the righ-t hand, whereas when the keyboard is reversed or invented, this will reverse the keys for left hand operation. The conductors 36 are .connected to one spring 57 of each pair while the common conductor 38 is connected to the other springs so that when any one push button or key is pressed, this will close the circuit of the respective solenoid. The keys can be quickly manipulated with the slightest manual effort for operating the punches through the aid of the electro-magnetic means.

The operation of the machine is as follows:

Supposing that .the carrier. 14 is in its fore- \most or card-receiving position, then a card 13 can be readily introduced by -placing in the guide 12 between the portions 15. The operator then moves the carrier rearwardly by pushing on the finger piece 49, which will raisethe contact fingers 48 olf' of the pattern card 42 during such rearward movement, and when the card 13 is moved to its rearmost position, the finger piece 49 is released land this lets the contact-members 48 down on the pattern card 42. Now, if the first column of digits on the pattern card 42 has a -perforation, then one of the fingers 48 will immediately make electrical contact through the porforation with the respective bar 44, and this will instantly energize the corresponding solenoid Iand cause the .punch operated thereby to punch the first hole in the card 13 automatically, and if, as illustrated, there are one or more successive columns on the card 42 having perforations, then, as vsoon as the rst perforation is made and the switch 52 is opened so as to restore the operating mea-ns, the carrier 14 and card 13 Will automatically advance one step, as Well as the contact fingers 48. Therefore, fthe :fingers 48 are removed from the first column and its perforation to the next column so that the respective finger 48 will spring down through the perforation of the latter 'column and repeat the automatic punching operation accordingly. This automatic operation is repeated until the fingers 48 reach a column on the pattern card 42 that is not perforated, when the card 13 comes to rest for manual operation. The automatic operation, even for several successive columns or positions, is accomplished rapidly, so as to lose no time, and

vwill be done before the operator is ready to press a key 58. The selective manual punching is done by'operating the keys 58, and Whenever the fingers 48 reach a position on the card 42 having a -perforation 42', then the automatic operation takes place instantly, and is repeated as required, so that the card 13 is ready for the next selective manual punching practically as quick as the operator is ready to pre-ss the next -key 58. In this manner, as the card 13 moves step by step, the punching is done automatically in those positions of the card 13 determined by the perforations in the ypattern card 42, While in the other positions of the card 13 it stops for manual-controlled punching, it being noted that as each perforation in the card 13 is completed by automatic or manual control, the card 13 advances one step and stops for manual control but only stops'for an instant in automatic control While the automatic punching is completed and then steps on for the next operation. By changing the pattern card 42, the results of an adjustable gangpunching machine are quickly attained, and thepreseirt machine obtains the results of gang-punching without the objections incident thereto and with economy by dispensing with the gang-punching machines and attendant labor and time. In lieu of the gangipunching of the cards 13, according to the perforations 42', the present machine automatically provides the ycard 13 with corresponding perforations during the intervals of manually-controlled punching and Without loss of time.

The term sheets in the appended claims is meant broadly for various blank objects or devices to be operated on in different ways, and furthermore, although the claims indicate that the sheet or object moves, same is to be taken in a broadsense as a relative motion of the parts, because the same result would be obtained if the sheet or object stood still and the rest of t-he maually-controlled Work-performing membersl to operate on the sheet when fed from position to position, and means for automatically controlling said members at some previously selected positions only of the sheet to perform predetermined repetition work without manual aid and leaving the rest of the work for manual control in the other p0- sitions of the sheet.
