ori-TCE This invention relates to stock quotation projecting machines in general and more especially to stock quotation projecting machines in which the motive power is running constantly and the tape pulling action only effective intermittently when the ticker operates.

Among the objects of the present invention, it is aimed to provide an improved stock quotation projecting machine including a tape feeding mechanism which is eective intermittently with the operation of the motor in cooperation with a continuously operating motive force. It is still another object of the present invention to provide an improved stock quotation projecting machine in which the tape pulling effect and the vibration dissipating effect are produced by one and the same means in cooperation with a continuously operating motive force.

o These and other features, capabilities and add vantages of the invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawing in which Figure 1 is a side elevation of a machine equipped according to the present invention;

Fig. 2 is afragmental enlarged side elevationpartly in section of a part of the control mechanism for the tape pulling device; and

Fig. 3 is a fragmental enlarged end elevation partly in section of a part of the control mechanism for the tape pulling device showing its connection with the rewind reel and the belt to the motor.

In the embodiment illustrated, there is shown the casing I of a ticker preferably of the high speed type from which the tape T passes across the light aperture formed on the extension 2 of the lamp housing 3. To facilitate movement of the tape T across the light aperture, there is preferably provided at the entrance end to the light aperture, a roller 4 and at the discharge end a roller 5.

From the light aperture, the tape passes down around the main tape puller, or tape pulling sheave 6 which is mounted on the shaft 'I extending through the casing 8 and journaled therein. The shaft I is operatively connected to the electric motor 9 by the driving connection now to be de- SClibed.

On the shaft 1, there is xed the worm wheel I0 which meshes with the worm I I freely mounted on the shaft I2. The shaft I2 is also journaled in the casing 8 below the shaft I and disposed at right angles to the shaft 1 to transmit to the shaft 'I andvin turn to the tape puller 6, an angular movement with a different center of rotation and also with a different velocity than that of the shaft i I2.

housing 8, there is fixed the pulley I3 which is connected by the belt I4 with the pulley I5 on the shaft I6 of the motor 9, which in the present instance is intended to continuously operate during the trading hours in which the machine is to be used and only interrupted at the end of the trading hours.

The shaft I2 inside of the casing 8 is provided with the` discs I 'I and I8 which are preferably fixed on the shaft I2 adjacent the bearings I8 and 20 to locate the shaft I2 in place. There is also xed on the shaftl I2, and to rotate therewith, a disc 2I which provides one of the clutch faces. The disc 2| is disposed adjacent to the worm II and the end of the worm II, to wit the face 22 forms one of the clutch faces to engage the face 23 of the disc 2| forming the other clutch face. The face 22 -of the worm II is normally maintained in frictional engagement with the face 23 of the disc 2l by the spring 24 which is tensed between the disc I'I and the collar 25 of the roller bearing ring 28, or thrust bearing, which collar 25 is spaced from the collar 21 of the ring 26 by the ball bearings 28. The collar 2'I of this bearing ring 26 engages the left hand end of the worm I I normally through the spring 24 to maintain the worm I I in engagement with the disc 2|.

The tape T is maintained in engagement with the pulling sheave 6 by the pressure roller 2,9 which is mounted on the end of the bracket 30 pivoted at 3l and provided with an adjustable weight 32. From the pulling sheave 6, the tape T passes up over the rewind reel 33 which is mounted on the shaft 34 journaled in the bearing 35 formed at the upper end of the arm 36 extending upwardly from the casing 8. The shaft 34 extends through the bearing 35 and has fixed thereon the sheave 31 which is connected by the belt 38 to the sheave 39 mounted on the shaft 1. The belt 38 is preferably composed of a yieldable substance such as a spring to facilitate slippage between the rewind reel and the shaft 'I which is particularly desirable as disclosed in this art due to the rewind reel increasing speed transmitted to the tape T caused by the increasing diameter of the paper roll being formed on the rewind reel in the course of rewinding.

The shaft 'I is operatively connected to the control arm 40 in the manner now to be described. The shaft 'I is provided with a pinion 4I in the On the shaft I2 and 4outside of the present instance fixed on the shaft 1 between the casing 8 and the sheave 39 and meshes with the small pinion 42 mounted on the stub shaft 43 extending from the side of the casing 8. The small pinion 42 is preferably provided with a hub 44 containing ball bearings 45 for engaging the shaft 43 and which hub 44 forms with the wings 46 and 41 a butterfly.

The wings 46 and 41 are preferably composed of a spring like resilient material and are connected to the hub 44 to extend tangentially therefrom and preferably formed on diametrically opposite sides of the hub 44. The butterfly formed by the wings 46 and 41 is adapted to cooperate with the finger 48 of the control arm 4D. This finger 48 is formed at the end of a bracket arm 49 pivotally mounted on the pin 50 extending from the arm 36. The finger 48 as shown in Fig. 2 preferably is provided with a tapered end 5|, as indicated The bracket arm 49 is preferably provided with a split tubular extension 52 to receive the end of the rod 53. This tubular portion 52 is preferably provided with ears 54 for the reception of the screw 55 by means of which the split tubular extension 52 may securely anchor the rod 53 against displacement. The rod 53 of the control arm 40 preferably is bent upwardly at 56 to extend up to the bend 51 to one side and above the level of the light aperture from which bend the rod 53 extends across the light aperture to the bend 58 where it extends downwardly to form the tape controlling nger 59 which may be a roller or the like.

The images formed of the characters or markings on the tape at the light aperture on the extension 2 will pass up through the objective lens formed in the housing 60 supported in place above the light aperture by the bracket 6I extending upwardly from the housing 3. The images so received by the objective lens in the housing 60 will then be directed onto the screen. In the present instance, such images will first strike the mirror 63, be reiiected onto the mirror 62 and then finally appear on the screen 64, such screen 64 and mirrors 63 and 62 being generally connected to one another to form what is known in the trade as the D housing.

From the foregoing, it will thus appear that when the ticker operates the tape T discharging therefrom will be drawn across the light aperture on the extension 2 by the pulling sheave 6 and wound on the reel 33. The finger 59 engaging the tape between the ticker and the light aperture will dissipate the vibrations transmitted 55 thereto by the ticker, such finger 59 being formed at the end of an extended control arm 40 which due to its weight and leverage will take up the slack formed in the tape as quickly as formed and consequently iron out the vibrations transmitted 60 to the tape by the ticker. Furthermore, when the ticker stops, the sheave 6 continuing to take up the tape will cause the loop formed under the finger 59 to be taken up and consequently the fin- 65 ger 59 to be raised thereby causing the finger 48 to be depressed into the path of movement of the wings 46 and 41 of the butterfly.

As soon as the finger 48 engages one of the wings, for instance the wing 46, it will cause the pinion 42 to come to rest, in turn anchoring the pinion 4| against rotation thereby to cause the sheave 6 to come to rest and thus discontinue the tape pulling action of such sheave 6. When such pinion 4| so comes to rest, it Will of course also 75 cause the worm wheel l0 to come to rest and react on the worm the threads of which will cause the worm to turn on the shaft I2 away from the disc 2| and in opposition to the spring 24 so that the clutch faces 22 and 23 will be separated and thus the worm be free to stop with the worm wheel I0 while the shaft |2 will continue to be operated with the motor 9.

In turn when the ticker again starts operating, it will initially form a loop under the finger 59 and when this loop is large enough so that the finger 59 in following it, causes the finger 48 to rise sufficiently to release the wing 46 or 41, the l butteriiy will of course be again free to operate and since there will constantly be an urge on the worm wheel by the spring 24 to bring the clutch faces 22 and 23 into engagement and also to cause the worm wheel to .rotate due to its large supporting surface on the shaft l2, the worm wheel will gradually cause the worm Wheel I0, pinions 4| and 42 to pick up speed to their normal speed so as to gradually cause the sheave 6 to come into normal tape pulling action again.

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.
