LIBRARY CARD PRINTING MACHINE Filed Oct. 17. 1932 5 SheetS-Sheet 5 ..im- Z Wirzss BY rra NEYS Patented June 19, 1934 PATENT OFFICE LIBRARY CARD PRINTING MACRINE George Van Dusen, Syracuse, N. Y., assignor to Gaylord Brothers, Syracuse, N. Y., a corporation o! New York Application October 17,
This invention relates to certain improvements in library card printing machines of the class set forth in the pending applications of Lloyd W. Moulten, Serial No. :394,531, filed September 23rd, 1929 and formally allowed August 2nd, 1932; serial No. 51l,816 filed January 28th, 1931 both of which applications have been duly assigned to Gaylord Brothers, a New York Corporation ot Syracuse, New York, the present application also involving the use of a type card or plate 01' the class set forth in the patent to Lloyd W. Moulten, No. 1,830,555, November 3rd, 1931 and also assigned to said Gaylord Brothers.
These machines are adapted to be used more particularly in public libraries and other places where books or other articles are temporarily loaned to borrowers with restrictions as to the time of returning, and the main object of the present invention is to provide a more expeditious means for recording upon the borrowers card or librarian's card suitable characters such as numbers for identifying the borrower and for recording the dates of loan and return of the borrowed articles.
In other words, I have sought to efiect these printing Operations through the medium of electro-magnetically operated devices and a normally open self-opening switch adapted to be operated by the insertion of the card to be printed into the machine for controlling the energizing of the electromagnet and thereby to avoid the use of electric energy except at such times as the card or cards are being inserted into the machine by the librarian or other attendant.
The main object, however, is to simplify the construction of the machine and at the same time to conserve the metered current used in the operation oi' the printing mechanism so that the machines may be manufactured and sold at a relatively low cost to permit their extended use to the smaller public libraries or business houses where card records are kept of various Operations or transactions, such for example, as the time of arrival and departure of workmen or the times of beginning and ending of certain classes of work having individual identification characters.
Other objects and uses relating to specific parts of the machine will be brought out in the following description.

Figure 19 is a diagrammatic view of an electrically operated card punching device together with a card operated electric switch for controlling the energizing of the electro-magnet, the card guide and card 'therein being shown in section.
As illustrated, this machine comprises a main supporting frame or housing of any suitable construction adapted to receive and support the various mechanisms hereinater described and is preferably substantially rectangular in top plan and provided with a top wall 1 having a movable lid section 2 hinged at 3 to Swing Vertically to and !rom its closed position, as shown more clearly in Figure 2.
This lid section forms a closure for a corresponding opening in the top 1 and is preferably arranged substantially midway between the front and rear ends of the frame with its rear end hinged thereto so that the front end may be rocked upwardly and rearwardly to its open position to permit access to the various mechanisms on the underside thereof and also to the mechanisms within the housing, which latter is also Caj &a
open at the bottom to pernt access to such meehanisms es are not available through the opening in the top.
The lower corners of the housing are provided with cushioned feet 3 of rubber or equivalent Inaterial adapted to rest upon a desk or other support to cleaden the noise incidental to the operation of the machine and also to avoid mutilation of the deslr, it being understood that the entire machine is suificiently small and light to render it easily portable from place to place as may be required for use in different parts of the same establishment.
The lid 2 and mechanisms carried thereby are quite similar to that set forth in pending application Serial No. 511.815 previously referred to in that it is provided with an upwardly and forwardly projecting card guide 4, a type bar guide 5 and a type plate guide 6, as shown more clearly in Figures i, 3, 4 and 5.
The guides 5 and 6 are disposed in substantially the same vertical plane transversely of the machine while the card guide 4 is disposed in a plane slightly in front of but parallel with the guides 5 and 6 and is preferably curved upwardly and forwardly from the upper face of the lid so that its open upper end may face the operator to enable the cards to be Conveniently placed therein and removed therefrorn.
The front end of the lid 2 is provided with a removable section 2' including the front wall 4' of the guide 4 to permit convenient milling of the guides 5 and 6, said section 2' being held in place by clamping screws 7, as shown by dotted lines in Figure .i.
The lid 2 is also provided with an integral platen 8 projecting downwardly from the underside thereof and extend'ng transversely across the greater portion of the width of the lid with its front face in relatively close proximity to the rear faces of the adjacent portions of the card guides 4 and 6, as shown more clearly in Figures 3 and 4, the lower end of said platen being provided with a forwardly projecting shoulder 8' forming a portion of the bottom of the card guide 6 for limiting the downward movement of the type card as a.
This type card a is similar to that set forth in Patent No. 1,830,555, previously referred to in that it is provided with a metal type plate a' detachably Secured thereto near one end and one side so that when the card is placed in the guide 6 its lower end will rest upon the abutment or shoulder 8' with its type plate a' in opposed relation to the movable platen hereinafter described.
The card guide 4 is adapted to receive a borrower's card b and is arranged in such manner that when the card is inserted therein, it will be directed downwardly across the front face of the platen 8.
The inner portions of the card guides 4 and 6 are arranged in overlapping relation transversely of the machine to cause similar overlapping relation of the inner edges of the cards a and b when they are inserted from the top downwardly through their respective guides in which case the inner edge of the card b will extend across the front face of the type plate a' to receive the impression therefrom when the movable platen is brought to its printing position, said type plate a being provided with raised printing characters such as the number used to identify the borrower.
The vertical guide 5 is arranged at one side of the guide 6 for the type plate a and near the corresponding side edge of the card guide 4 for receiving a vertically adjustable type carrier or bar 9 which is similar to that set forth in the pending application Serial No. 511,&16, previously referred to in that it is adapted to receive and support a multiplicity of, in this instance four, type plates 10 arranged in sequence lengthwise of the bar to extend across the obverse face thereof and displaceable from the lower end thereof but are normally held against such displacement by a spring detent 10'. as shown more clearly in Figura 12.
These type plates are provided with embossed type representing different dates of borrowing or returning of the borrower's card b which, as previously stated, is of sufflcient width to overlap upon the type plate a' of the card a to receive the impression of said type pIate opposite each date impression, as shown more clearly in Figure 16.
When the type bar 9 is in operative position, its type plates 10 will be in substantially the same transverse vertical plane as the type plate a' on the card a, as shown more clearly in Figures 3 and 4.
The reverse side of the type bar 9 is provided with a tooth rack 11 adapted to be engaged by a pinion 12 on the inner end of a rotary shaft 13 which is journaled in registering openings in the left hand side of the frarne 1 and a guide block 40 to extend to the outside of the frame where it is provided with a hand wheel 14 by which it -may be rotated, for moving the type bar 9 vertically step by step or one type plate space at a time. `See Figures 4 and 10.
The rear face of this type bar is provided with longitudinally spaced recesses 15 corresponding to the spacing of thetype plates 10 for receiving a detent 16 which is spring pressed into registering recesses 15 as the bar is adjusted vertically for frictionally holding the bar in its adjusted position, as shown more clearly in Figure 3.
suitable means is provided for transferring the lmpressions of the type platcs 10 and a' onto the card and for this purpose the opposite ends of an ink ribbon 17 are attached to suitable reels 18 and 18' to extend across the front face of the platen 8 in horizontal alinement with said type plates when the bar 9 and card a are adiusted for use in their respective guides 5 and 6, see Figu'es 3 and 4.
The portion of the ink ribbon extending across the front face of the platen 8 is passed between a pair of thin sheet metal stripper plates 19 having suitable openings therethrough registering respectively with the type plates 10 and a' through which the impressions upon the card are made when the movable platen is operated in a manner hereinafter described.
That is, when the type card a is inserted from the top downwardly into its guide 6 and against the limiting stop 8' its type plate and adjacent portion of the card will be interposed between the rear stripper plate 19 and front face of the platen 8 while the borrower's card b, inserted from the top downwardly through its guide 4, will be positioned in front of and adjacent the front stripper plate and, therefore, across the front face of the ribbon 17.
The ribbon 17 is adapted to be moved endwise intermittingly at each operation of the movable plunger and is substantially identical with that shown in the pending application Serial No. 511,816 previously referred to and, theretore, it
will be unnecessary to further describe the same for the reason that it forms no part of the present invention except broadly in combination with the means for actuating the movable platen.
In like manner the means for adjusting the type bar 9 vertically and also the means for locking and releasing the lid 2 in and from its closed position are similar to the pending application referred to and, therefore, need not be further described herein.
M ovable platen A horizontal guide block is rigidly Secured by clamping screws 20' to the underside of the top 1 of the frame directly in front of the platen 8 when the lid 2 is closed and is provided with a forwardly and rearwardly extending guide opening 21 in which is mounted a forwardly and rearwardly slidable platen supporting bar 22 having its rear end provided with a transverse recess 23 for receiving a U-shaped metal clip 24 carrying a pair of platens and 25', see Figures 3 and 4.
These platens 25 and 25' are arranged in opposed relation respectively to the active type plate 10 of the type bar 9 and the type plate a' of the card a when the latter is inserted in its guide 6, but for convenience of description, they, together with their supporting slide 22 may be regarded as the movable platen or one of the printing elements adapted to cooperate with the opposed printing element or platen 8 for impressing the type of the plates 10 and a' upon the card b. See Figures 12 and 16.
The lower walls of the guide opening 21 preferably consist of longitudinally spaced bars 26 Secured to the underside of the super-posed portion of the block 20 by means of screws 26' to permit access to the guideway 21 when desred.
It is now clear that the platen 22 is movable rectilinearly or forwardly and rearwardly into and out of printing coaction with the platen 8, said movable platen being returned to its forward position with its platen members 25 and 25' in spaced relation to the platen 8 in a manner hereinafter described.
Platen Operating means I preferably employ electromagnetically operated means for moving the platen 22 to its printing position in combination with means actuated by the card as b when inserted into the machine for causing the operation of the electromagnet so that no current will be used except during the almost instantaneous act of inserting the card and removing it from the machine.
This electromagnet preferably consists of a solenoid 27 having a. movable plunger 28 connected through the medium of a turnbuckle 29 to the lower end of an upright lever 30 which is pivoted at 31 to a lug 32 on the underside of the block 20, the upper end of said lever being extended through an opening 33 in the sliding platen 22 some distance to the front of the platen blocks 25 and 25'.
The solenoid 27 is mounted in a suitable bracket 34 on the underside of the top 1 of the main supporting frame just at the rear of the lid 2, as shown more clearly in Figures 2 and 3, the front end of the plunger 28 being pivotally connected at 28' to the rear end of the trunbuckle 29. as shown in Figure 2, while the front end of the turnbuckle is pivotally connected at 29' to the lower end of the lever 30.
Card controlled solenoid switch Current may be supplied to the solenoid 27 from any available source through the medium of wires or 'sables 35 which may be provided with an electrc plug adapted to be inserted in any available socket, not shown. See Figure 1.`
A card controlled normally open self-opening electric switch is connected in the solenoid circuit and comprises a pair of contact terminals 36 and a movable switch plate 37, the terminals 36 being connected to suitable binding posts 38 by means of conductors 39, shown by dotted lines in Figure 5 and by full lines in Figure 6.
These conductor bars 39 are mounted upon a supporting block 40 which, in turn, is secured by bolts 41 to a bracket 42 on the left hand side of the main supporting frame 1, the bars 39 being insulated from the block 40 by insulating members 43, shown more clearly in Figure 6.
It will be noted upon reference to Figure 2 that the cables 35 are also connected to the binding posts 38 so that when the switch plate 37 is moved into contact with the terminals 36 the circuit will be closed through the solenoid 28.
The switch plate 37 is mounted upon a supporting plate 37' of insulating material which, in turn, is Secured to one arm of a lever 44, the latter being pivoted at 45 to the block 40 and having its other end offset laterally at 46 and provided with an upturned extension 46' in the path of movement of the card b when the latter is inserted from the top downwardly through the guide 4". the portion of the card b being shown by dotted lines in Figure 8.
That is, the lever 44 extends forwardly and rearwardly from its pivot 45, the rear end being provided with the upturned extension 46' to be engaged and depressed by the insertion of the card through the guide 4", thereby rocking the front end of the lever upwardly to bring the plate 37 into contact with the terminals 36 and thereby to close the circuit through the solenoid for the purpose of moving the platen 22 to its printing position simultaneously with the depression of the rear end of the lever by the card.
The block 40 is arranged to underlie the left hand side of the card guide 4 and is provided with a vertical guide slot 4" forming a continuation of the guide 4 and into which the extension 46 of the lever 44 is adapted to project in relatively close relation to the outer wall of the groove 4", as shown in Figure 8, and for a purpose presently described.
Punchi'g dies 'For this purpose :nale punching die 47 is reciprocally novable endwise in a guide opening 47' in the block: into and out of punching coaction with the naie die 48, the guide opening 47' being exte. eci across the lower end of 'the supplenental card guide 4", as shown more clearly in Figure 7'.
The .female die 48 preferably consists of a tubular sleeve of steel or other hard metal insorted in an opening 48' in the block 40 coaxial with the male die 47, said sleeve serving also to receive the cut out portions of the card and to deliver the same into a receiving cup or tray 49, shown in Figures 2, 3 and 7.
The tray 49 is supported in an upright positon upon a ledge 49' on the bottom of the main frame l and just at the rear of the block 40 with its upper end open and disposed in a plane slightly below but closely adjacent the rear end of the sleeve 43, as shown more clearly in Figure 7.
The inner end of the guide opening 47' and adjacent end of the punching die 47 are preferably square in cross section and of about the same cross sectional area to hold the die against angular movement about its axis.
The outer end of the guide opening 47' is enlarged to receive a coil spring 50 engaging the enlarged front end of the punching die 47 for returning the latter to its normal position immediately following each punching operation.
The upper front end of the die 47 is slightly undercut to form a cutting edge 51 adapted to move across the lower end of the guide 4 and into the adjacent end of the female die 48 for cutting away the adjacent corner of the card b.
I'he rear end of the die 47 is provided with a reduced rearward extension stop 47" normally projecting across the lower end of the` guide groove 4" and having its upper face disposed in a plane a distance below that of the cutting point 51 to regulate the line spacing of the impressions made by the registering type plate 10 at each successivo printing operation. See Figures 5, 7 and 8.
That is, as the card is cut away by the punch 47, it allows the card to be moved farther downwardly a distance corresponcling to the cut away portion before engaging the upper face of the extension stop 47", thus permitting the line spacing of the type impressions upon the same card as b when the latter is successively inserted in the guide slots 4 and 4".
The extension 47" is provided with a vertical slot 47"' for receiving the up'wardly projecting extension 46' of the switch lever 44 so that when the card is inserted from the top downwardly through the guides 4 and 4" the lower edge thereof will first engage and depress the extension 46 of the lever 44 for moving the switch plate 37 into contact with the terminals 36, thereby closing the circuit through the solenoid 27 for operating the platen 22 to its printing position.
The front end of the lever 44 is somewhat heavier than its rear end to aid in automatically opening the switch, which opening movement is made more positive by the use of a comparatively light coil spring 44', as shown more clearly in Figure 5.
When the lever 44 is in its normal open position the extension 46' will project through the slot 47"' some distance above the upper face of the extension 46' and, therefore, when the card b is inserted from the top downwardly through the guide groove 4" its lower edge will engage and depress the rear end 46 of the lever 44 before it comes in contact with the upper face of the extension stop 47" for closing the switch.
This closing of the switch and resultant energizing of the solenoid 27 not only causes the op eration of the platen 22 'to its printing position but also causes the operation of the punching dic 47 to its punching position.
For this latter purpose, the platen is provided with a lateral extension 53 carrying a screw 54 for engaging the front end of the plunger 47, as shown more clearly in Figures 3, 5 and 7, said screw being adjustable in a threaded opening 54' in the ofiset extension 53 and held in its adjusted position by a lock nut 54".
It will now be understood that when the card as b is inserted from the top downwardly through the guides 4 and 4" the lower end of the card will engage and depress the rear end 46' of the lever 44, thereby closing the switch plate 37 onto the terminals 36 at which time the lower end of the card will have been brought into contact with the upper face of the extension 47" of the punch 47 as a limiting stop therefor.
This closing of the switch will energize the electromagnet 27 for Operating the platen 22 to its printing position against the action of the spring 50 and at the same time the later-al oset portion 53 on the platen 22 will be moved rearwardly therewith to cause the rear end of the screw 54 to engage the front end of and to operate the punch 47 for punching away the portion of the lower end of the card resting upon the upper face of the extension 47" and thereby to allow the card to be advanced one line space for the next succeeding printing and punching operations.
It, therefore, follows that the printing and punching Operations are simultaneous and immediately follow the closing of the switch plate 37 upon the terminals 36 so that these Operations are substantially simultaneous with the closing of the switch.
These Operations are practically instantaneous upon the insertion of the card from the top downwardly through the guides 4 and 4" and against the extension 47" and immediately following these Operations, the card with the impressions from the type plates 10 and a' on the rear face thereof is withdrawn.
That is, the impressions from both type plates are made simultaneously upon the rear face of the card b, it being understood that when the card b is printed and withdrawn from the machine, the type card a will also be withdrawn, so that the machine may be used with the same or a different type card a to print upon the same or a different borrower's card b.
The rearward movement of the platen 22 to its printing position is utilized for intermittingly operating the feeding mechanism for the ribbon 17, and for this purpose the extension 53 is provided with an adjustable screw 56 for engaging the rear end of a sliding member 57 which, in turn, is connected to the ribbon feeding mechanism similar to that shown in the pending application Serial No. 511,816 previously referred to.
It will be readily understood from the foregoing description that by the employment of a solenoid as 27 or equivalent electromagnet for Operating the platen 22, punch 47 and ribbon feeding mechanism, these Operations will be practically instantaneous, thereby avoiding the use of any current except when the solenoid is actually energized.
Under these conditions, the operation of the machine is extremely economical, expeditious and highly emcient and may be used in the smaller llbraries and in many other relations where the expense o! operation of a continuously running motor would be prohibitive.
operation When the lid 2 of the !rame 1 is closed, the type card a will be inserted from the top downwardly through the slot 6 until its lower end engages the limiting stop 8' thus bringing the type plate a' into registration with the platen member 25'.
At about the same time the hand wheel '14 will be adJusted rotarily for affecting the vertical adjustment of the type bar 8 and thereby to bring one of its type plates lo into registration with the other platen member 25.
The type card b, known as the borrower's card, will then be inserted from the top downwardly through the guides 4 and 4" until its lower edge is brought into engagement with the upper face of the extension 47" of the punching die 47 during which operation the lower edge of the card b will have engaged and depressed the rear extension 46' oi' the lever 44 for closing the switch plate 37 upon the terminals 36.
This closing of the switch causes energization of the solenoid 27 for moving the plunger 28 forwardly and, through the medium of the connection 29 and lever 30, causes the rearward movement of the platen 22 to its printing position.
During this rearward movement of the platen, the member 25 will cooperate with the registering type plate 10 for impressing the type upon the rear face of the card b while at the same time the other platen member 25' will cooperate with the type plate a' for making the impression of said type upon the same rear face of the card b.
The rearward movement of the platen 22 and its iateral offset extension 43 will cause the screw member 54 on said offset extension to engage and operate the punch die 47 to punch away a portion of the adjacent lower corner of the card b and at the same time the screw member 56 will be brought into engagement with the slide 57 for Operating the ribbon feeding mechanism.
It is now clear that the single act of inserting the card b from the top downwardly along the guides 4 and 4" and resultant closing of the switch causes the energizing of the electromagnet 28 and forward movement of its plunger 28' and that this forward movement of the plunger not only forces the platen to its printing position ior making impressions of the type plates 10 and a' upon the same face of the card b but also effects the operation of the punching die 47 and ribbon feeding mechanism.
Immediately following these Operations, the cards b and a are withdrawn from the machine ready for a repetition of the Operations upon another borrower's card b in which case another identifying type card a would be used, it being understood that each borrower not only has a card b but the librarian also has a corresponding card a with the number or other identification character thereon for identifying the owner of the card b.
That is, immediately following the depression of the extension 46' of the lever 44 for effecting the operation of the movable printing platen, the punch 47 will be operated to cut away the lower left hand corner of the card which then engages the stop 47, thereby allowing the return of the lever 44 by the spring 44' and also permitting the removal of the printed and punched card, it being understood that the same card may be reinserted in the machine to repeat the printing and punching operation in the next succeeding line in which case the upper wall of the cut away portion will efiect the depression of the lever 44 until it engages the stop 47", thus causing the successive print to be made in a different line upon the card.
In the modification shown in Figure 19, the platen 22 is indicated diagrammatically and together with the plunger 47 are adapted to be operated directly by the plunger 28 of the solenoid 27 or in the same direction of movement of the plunger when the solenoid is energized.
Although the mechanism shown and described is particularly simple, practical, economical, and highly eflicient, it will be evident that various changes may be made in the detail construction :vithout departing from the spirit of the inven- What I claim is:
1. In a card printing machine, cooperative printing elements between which the card is` adapted to be inserted and removed, a card-guide extending beyond the card inlet side of the machine, in combination with an electro-magnet and a circuit therefor including therein a normally open electric switch, means actuated by said magnet when energized for Operating one of said elements to print upon the inserted card, and means closely adjacent one side of the card guide and adapted to be engaged by the inner end of the corresponding side of the card for closing the switch.
