Claims.

This invention relates to page printers in general and more particularly to combination page printers and projectors.

Among the objects of the present invention, it

5 is aimed to provide an improved page printer and more particularly an improved combination page printer and projector by means of which two areas of the printed sheet may be inspected at the same time, as an instance an area of the in printed matter as it is being printed and an area of the printed matter previously printed.

It is still another object of the present invention to provide an improved page printer having a tape feeding mechanism by means of which the tape feed may be reversed after it has been printed for a predetermined length of tape and then the advance feed resumed to read back the previously printed tape.

It is still another object of the present inven-' tion to provide an improved means for changing the advance and reverse feed of a tape.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of one specific embodimeni thereof illustrated in the accompanying drawings in which Figure 1 is a transverse section of a cabinet showing a side elevation of the main elements of the improved combination;

Fig. 15 is a fragmentary elevation of a portion of the tape.

In the embodiment shown, there is illustrated a main cabinet I typical of the broad tape projectors today in use having a rear wall 2 and a front wall 3. The front wall 3 in the present instance is provided with an opening 4 to the inner borders of which there is secured a main projection screen 5. The cabinet I is preferably provided with another window and projection screen 10 which in the present instance is also associated with the front wall 3, see the small opening 6 and auxiliary screen I in the present instance spaced from and positioned below the window 4.

Associated with the main screen 5, there is 16 contained in the housing It and then passed to 95 the inclined reflector l4 and by the reflector ll deflected onto the rear face of the screen 5 to be legible from the outside thereof. 8

The tape ll may be, passed to the light ape ture from any suitable tape advancing means, 30

such as the intermittent feed of a broad tape ticker or by a continuous feed through the ticker or as a previously printed strip by a tape advancing roller.

In the present instance. there is shown a broad tape ticker I! of the Dow-Jones type. The tape H whether coming from the ticker I! as it is being printed or from a previously printed roll is generally initially mounted on a shaft It to constitute a supply reel. In normal tape feeding to operation, the tape ll after leaving the light aperture provided by the condensing lens I 0 passes over the roller 20, then around the roller 2| and from the roller 2! contacts the roller 22 and then upwardly to the roller 23 and around as the roller 24 at the end of the arm 25 and then around the tape advancing roller 28 and up onto the shaft 21 of the take-up reel.

The arm 25 is preferably pivoted at 28 as shown and provided with a mercury switch 2! and so a weighted outwardly extending arm-20.. The mercury switch 29- is connected by the leads 3| and 32 to the conductors and It of the control wires hereinafter to be described.

The tape pulling roller 26 is drivinsly con- 5;

nected to the motor 35 and may either pull the tape as it is supplied to the take-up reel 21 when the motor 35 is rotated in one direction or pull the tape from the supply reel 21 when the motor 35 is rotated in the reverse direction.

In the ordinary operation of the machine when the tape is merely being advanced across the light aperture at the condenser |6 from the supply shaft |6 through the ticker to the take-up reel 21, the tape pulling roller 26 will of course be rotated by the motor 35 to pull the tape toward the take-up reel 21.

There will now be described and as constituting an important part of the present invention the mechanism for reversing the rotation of the motor 35 and tape advancing roller 26 to unwind the tape from the take-up reel 21 and subsequently rewind it and at the same time when rewinding it permit scanning or inspecting the tape previously printed either directly or through the projection mechanism here provided on the screen 1.

After the tape leaves the roller 22 and before it engages the roller 23 in the present instance, it first passes across the light aperture formed by the glass plate 36 and then passes over the recess forming support 31. To one side of the glass plate 36, there is provided a source of light such as the lamp 38 with associated optical means to direct a beam of light through the lamp at the glass plate 36 so that the image impressed light beam will be received by the inclined reflector 36 by which it will be deflected upwardly through the objective lens unit contained in the casing 46 and from there passed to the inclined reflector 4| by which it will be deflected onto the rear face of the small screen 1 to form images to be read on the outer face thereof.

Opposite the aperture support 31, there is positioned the roller 42 formed at the end of the arm 43 pivoted at 44 and having connected thereto another arm 45 to which is connected the mercury switch 46 from which the leads 41 and 46 pass to the conductors 46 and 56 forming part of the control wires hereinafter to be described.

The roller 42 is urged to exercise a pressure against the tape so that when it registers with an opening in the tape, such as the opening 5|, it will be forced into the recess formed in the support 31 and rock the mercury switch 46 to interrupt the current passing through the conductors 46 and 50 in turn to effect the reversal of the motor 35 back to normal. This opening 5| is, preferably formed at the very beginning of the tape at the beginning of a day's run. The reason for this position of the aperture 5| in the tape I I is that after a length of tape II has been wound up on the take-up reel 21 at least long enough to have passed upwardly out of the light aperture formed at 36 and it is then desired to examine the tape so passed, it is only necessary to reverse the operation of the motor 35, whereupon the rotation of the tape puller 26 will be reversed to permit the tape II to be drawn down past the light aperture at 36 until the opening 5| in the tape registers with the recess support 31 whereupon the switch 46 will be actuated to cause the, motor 35 again to be reversed to normal operation, whereupon the tape puller 26 will again draw the tape back upwardly across the light aperture at 36.

When the tape is being drawn downwardly by the tape puller 26 in the act of unwinding the tape II from the reel 21, the devices now to be described will be actuated in the manner indicated. The roller 2|, see Fig. 9, will first move to the left due to the pull exercised thereon by the weight 25|. The weight 25| is adjustably mounted on the rod 52 secured to the shaft 53 of the gear 54 in mesh with the gear 55 on the shaft 56 to which is fixed the drum 51 to which in turn is attached the flexible tape 56 preferably composed of canvas or the like which extends upwardly from the drum 51 to and around the idler 56 and then is connected to the carriage 66 in which is rotatably mounted the roller 2|. The carriage 66 constituting a shuttle has secured at its ends the pairs of guide rollers 6| and 62 travelling in the slotted guideways 63.

Projecting rearwardly from the ends of the carriage 66 inside of the rollers 6| and 62, there are provided the spring fingers 64 and 55 which are adapted to frictionally grip and hold the diminished ends 66 and 61 of the roller 66 in the position shown in Fig. 9, when as an instance the tape II is being drawn across the light apertures at 6 and 36 by the tape puller 26.

When as an instance, it is desired to unwind the tape it is first necessary to reverse the motor 35 to cause the tape puller 26 to draw the tape downwardly from the take-up reel 21, thereupon, the loop controlling the finger 24 is in position or remains in position to maintain the switch 29 in circuit making position and permit the formation of sufficient slack in the tape so that the weight 25| will come into operation moving down in the direction of the arrow 66 of Fig. 10, thereby actuating the drum 51 to take up the tape 56 and draw the roller 2| in the direction of the arrows 16 of Fig. 10. The shuttle 66 in this movement will carry the roller 66 with it until it strikes the arms 1| and 12 of the brackets 13 and 14 respectively. These brackets have the upwardly inclining projections 15, see Fig. 6 having shoulders 16 to the front thereof for cooperation with the projections 1| and 12 to position the roller 66.

The brackets 13 and 14 are preferably secured to the guideways 63 by the pins 11 and 16. After the roller 68 is so positioned in the brackets 13 and 14, the shuttle 66 will continue in the direc-.

tion of the arrows 16 until the roller 2| passes the tape into driving engagement with the drive roller 16 on the shaft 66 and to which is connected a beveled gear 6| in mesh with the beveled gear 62 at the end of the shaft 63 extending upwardly into driving engagement with the shaft of the tape pulling roller 26.

As soon as the roller 2| presses the tape into frictional driving engagement with the driven roller 16, at such time rotated in the direction of arrow 64 of Fig. 10, the tape II will be draped down into the storage space 65 formed between the partitions 66 and 61, Fig. 4, and due to the fact that the roller 66 is pressing the tape into advancing engagement with the driven roller 66, the tape being advanced if at all by the ticker l5, will be draped down into the storage space 65 to the rear of the partition 61.

The roller 66. see Figs. 1 and 9 to 13 is fixed on the shaft 66 which is drivingly connected to the shaft 66 and in turn drivingly connected to the shaft 6| of the blower in the housing 62. The blower shaft 6| is constantly rotated in the same direction to impart a constant rotation in the direction of the arrow 63 in Fig. 10.

When as heretofore noted, however, the opening 5| registers with the roller 42, the switch 46 will be rocked to cause the motor 35 to be reversed into normal rotation thereby reversing, not only the rotation of the tape pulling roller 26 but When all of the tape I draped mm the storage space 33 has been taken up, the continued rotation] of .the tape puller 23 will then exercise a pull through the tape II on the shuttle 33 to returnit to the normal positionshown in Fig. 3. On its return, the cams 33, Flg. 8, of the spring fingers 34 and-36 will engage the diminished ends 66 and 31 02 the roller 33 and ilrst raise it above the shoulder 13 and then carry it back with the shuttles" to the position shown in Fig.9.

The main lead 33 is connected to the conductor 50 which is connected by the conductor 43 with the switch 46 which in turn is connected by the conductor 41 with the conductor 43 which is connected to'the windings oi the electromagnet, I33 which is in turn connected by the conductor III to the conductor I32 of the reversing button I33 and by the conductor I04 to the restoring button I05.

The reversing button I03 is connected by the conductor I06 to the conductor I01 which is connected to the return main lead I03. The restoring button I05 on the other hand is connected by the'conductor I09 to the contact of the relay nected to the main le'ad 99 bythe conductor II4,

the other side of said motor-96 being in turn connected bythe conductors H and H6 to the switch II3 which is connected to the return lead I08 by the conductor II1.

The lamp 9 in turn is connected in the order named by the conductors I I8, II9, I and H2, switch H3 and conductor II4 to the main lead 99, the lamp being also connected in the order named by the conductors I2I, I22 and H6, switch H3 and conductor II1 to the return lead I03.

During normal operation, that is when the parts are positioned as shown in Fig. 9 and the tape I I is normally being advanced upwardly past the light apertures I0 and 36, the spring I23 is free to maintain the arm I24 against the adjustable stop I 25 with the switch arms I26, I21 and I28 engaging the contacts I29, I30 and I3I respectively and the switch arms I32 and I33 separated from their respective contacts H0 and I35.

In this position, the current will be passing from the main lead 99 through the armature 98 of the motor 35 in the direction of the full line arrows I36 and I31. As an instance, thecurrent will then pass from the main lead 99 in the order named through the conductor II4, switch II3, conductors H2, I20 and I38, field 91, conductors I39 and I40, rheostat I4I, conductor I42, controlbutton I43 and both to the conductor I45 and to the conductor 34. If the switch 29 is closed and switch I46 is open, the current will flow through the conductors 34 and 32, switch 29 and conductors 3I and 33 to the conductor I49. From conductor I49 and again in the order named, the current will pass by way of switch arm I26, contact I29, conductors I50 and HI,

Whenitisdesiredtoreadorexamineth previously printed tape II, it is only necessary first to press thebutton I33 when theelectro- 30 magnet I33 will be energized to rock the arm'I24 where its switch arms I21, I32 and I33 will engage the contacts 221, III and I33 respectively and the switch arms I23, I21 and I23 will be separated from their respective contacts I23, I33 33 and I3I. In this pomtion, the motor 33 will be reversed, current then flowing in the reverse direction to that shown by the arrows I33 and I31 and the lamp 33 will be normally extinguished. As an instance, the current can now be traced I from the main lead 33' in the order named through conductor II4,pswitch II3, conductors 2, I20 and I33, held 91, conductors I33 and IN, switch arm I33, contact I35, conductors I33 and I62, armature 93, conductors I3I and I30, contact I29, switch arm I21, conductors I62, I63, I22 and H6, switch H3 and conductor "1 back to the return lead I03. At the same time, after releasing the button I03, the current will also continue to pass through the electromagnet I00 so long as the switch 46 is closed, although both the switches I46 and 29 will now be closed, due to the fact that the current is interrupted by separating the switch arm I26 from the contact I29. The current to the electromagnet I00 can now be traced from the main lead 99 in the order named through conductors 50 and 43, switch 46, conductors 41 and 49, electromagnet I00, conductors IM and I04, button I05, conductor I09, contact IIO, switch arms I32 and conductors I65 and I01 back to the return lead I08.

In this setting, the lamp 36 will be normally extinguished but may be illuminated by pressing button I66 when the current will be established from the-conductor I connected to the lamp 39 in the order named through conductor I 61. button I 66 and conductor I68 to the conductor I63 which is connected to the return lead I08 by conductors I22 and H6, switch H3 and conductor I I1 and which lamp 38 in this setting will be connected to the main lead 99 by the conductors I56, II9, I20, and H2, switch H3 and conductor II4. This abnormal illumination of the lamp 36 may be desired should a trader wish to watch the tape unwinding so that he may stop it before it entirely unwlnds should he so desire. 'On the other hand, if it is permitted entirely to unwind the tape, then the arm 43 is relied upon automatically to start the rewinding operation. In other words, when the beginning of the tape I I has been reached so that the opening 5i registers with the roller 42, the switch 46 will be rocked to interrupt the current thereby de-energizing theelectromagnet I00 to enable the spring I23 again to actuate the switch arms to the position 7 shown in Fig. 14 when the current of the motor 35 will be restored to its normal fiow, that indicated by the arrows I36 and I31 and the tape puller 28 will again pull the tape upward.

Should the rewinding be allowed to run its natural course, when all of the tape in the storage space 85 as well as to the rear of the partition 81 has been taken up, the continued pull on the tape I I by the puller 26 will draw the shuttle 68 rearward, first to pick up the roller 58 and finally to press the roller 68 against the arm I88 to interrupt the current and arrest the actuation of the tape puller 26. unless the switch 28 is still closed so that the tape pull will now be again controlled entirely by the formation and dissipation of the loop I51.

Should the trader wish to retard the rewindin action aforesaid, he can do so by regulating the rheostat Ill in the usual way. On the other hand, should he wish to effect the rewinding of the tape II in an intermittent feed, he can do so by operating the button I43.

As shown in Figs. 12 and 13, the feed transmitted by the rollers 88 and 88 is permitted to take up the tape II during an unwinding action, should the ticker I5 be supplying tape during this period thus insuring the advance of the tape II so supplied across the light aperture at I8.

The mechanism now to be described relates to festooning the tape II in the storage space 85. Here there are two large discs I18 and HI mounted on alined shafts I12 and I13 respectively. The opposing faces of the discs I18 and "I are provided with spiral rows of alined round holes I14 to receive the spring pressed heads I15 and I18 protruding from the ends of the composite rods I11. Adjacent the inner faces and to the rear of the partition 88, there are provided a plurality of pairs of spring fingers I18 extending rearwardly and in the direction of the arcuate path of travel of the recesses I14, one set of pairs of spring fingers I18 for each pair of holes I18; and to the front of the partition 81 and extending upwardly, there are provided a plurality of pairs of spring fingers I18 also extending in the direction of the arcuate path of travel of the holes I14, one set of pairs of spring fingers I18 for each pair of holes I14.

Initially the rods I11 are positioned in the alined pairs of spring fingers I18, one rod for each alined set of pairs of spring fingers I18. These rods I11 are successively transferred from the fingers I18 to the fingers I18, the timing of the transfer being predetermined to correspond to the feed of a loop or festoon of tape II into the storage space 85. In Fig. 4, one festoon has been formed by the uppermost rod I11 and the second festoon is in the process of being formed by the next topmost rod I11.

The number of rods I11 and cooperating parts will of course depend upon the length of tape that is expected to be festooned or stored in the storage space 85. Preferably the discs I18 and I1 I will be intermittently actuated, a Geneva drive being here provided, see the Geneva gear I88 mounted on the shaft I8I to which is fixed the gear I82 in mesh with the gear I83 on the shaft I84 on which is also fixed the gear I85 in mesh with the gear I88 on the shaft I13. On the shaft I13, there is also fixed the sprocket gear I81 connected by the sprocket chain I88 to the sprocket gear on the shaft I88 mounted in bearings extending to the front of the partition 86, on the other end of which shaft I88 there being secured another sprocket gear I88 connected by the sprocket chain I8I with the sprocket gear on the shaft I12 in order simultaneously to transmit the same rotative motion to the discs I18 and I1 I.

The Geneva gear I88 is positioned to be engaged by the pin or tooth I82 extending from the hub I83 fixed to the shaft I88 of the gear I85 which is in mesh with the gear I86 on the shaft 88 of the roller 18.

From the foregoing, it will of course appear that as the rotation of the roller 18 is reversed with the reversal of the motor 85, the intermittent rotation of the discs I 18 and HI will likewise be reversed.

It will also be noted thatv at least one of the discs, as an instance the disc I18, is provided with a spur I 88 forcooperating with the latch formed by the pivotally mounted lever I88 having two downwardly extending supports for the rollers 288 and 2M. The lever I 88 is pivoted at 282 and is limited in its movement by the two stops 283 and 284. In addition, the rear'end of the lever is provided with a stop shoulder 285 to engage the shoulder 285 of the spur I88 and arrest the movement of the discs I18 and HI when rotating in a direction opposite to that of the full line arrow 281 of Fig. 4. The front end of the lever I88 is provided with a projection 288 to cooperate with the roller 288 on the lever 2 I 8 which is urged into cooperative engagement with the projection 288 by the spring 2| I.

In other words, this latch will enable the spur I88 to pass the lever I88 when the discs are operating in the direction of the full line arrow 281 but obstruct its return movement when the discs I18 and "I are rotating in the direction of the dotted line arrow 2I2.

In order to facilitate festooning the tape in the storage chamber 85, the lower end of the chamber 85 is provided with a suction pipe 2I3 which is connected with the blower 82. As the air is sucked out of the chamber 85, it is preferably directed through the lamp housing 8 to facilitate ventilating the same.

For this purpose, the blower 82 and lamp housing 8 are connected with the discharge conduit 2 I.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
