invention relates generally to stock s particular reference to an improved type of stock quotation projecting machine.

It is frequently desirable to project the markings on a tape emanating from a stock ticker toward two or more distinct and different observation areas.

For example,

it may in certain cases be desirable to display these markings into two rooms reserved respectively for men and women, or it markings toward a mai also toward or into a private It is an object of my present invention to promay be desirable to project the n observation area and office or the like.

ject to provide an apparatus which embodies a maximum of simplicity pense.

and a minimum of exrecourse to any more than a single stock ticker and a single projecting acter.

It is a particular featu device of normal charre of my invention, pursuant to the foregoing general objects, to provide a projecting device whic h is so constructed that the single source of light customarily embodied therein may be employed to the greatest advantage in creating directable beams of provide a pair of outlet and I also provide suitable tape successively across light.

differently More particularly, I apertures for the light, means for drawing the these two apertures.

A further feature of my invention lies in arranging the two apertures above referred to in mutual parallelism and ship, and to provide t in side by side relationape-pulling means and guiding means for directing the tape first across one of the apertures in one direction and thenacross the other aperture in the opposite direction.

For the attainment of the foregoing objects and such other objects as may hereinafter appear or be pointed out, I have illustrated several forms of my invention in the accompanying drawings,

wherein Figure 1 is an elevational view, largely diagrammatic, of a machine embodying the features of my present invention;

Figure 2 is a view 'tak ment of a tape-pulling m Figure 3 is a plan view jecting device, showing t tape is guided across th en from the left of Figomittedfor the sake'of possible arrangeechanism;

of a portion of themehe manner in which the e apertures referred to;

Figure 4 is a view taken substantially in the same direction as Figure 1, showing one practical installation of the present character;

Figure 5 is a perspective view of an important element of the tape-guiding means; and I Figure 6 is a diagrammatic representation similar to Figure 1 and illustrating a modification.

guided downwardly around rollers 13 and 14 toward at suitable mechanism. The latter wheel 17, and thereby driving the shaft 18. The tape 11 may be made to pass downwardly-beneath wound, it may then pass onto a mandrel 21. The latter may be rotated or driven from the shaft 18 by means of the belt 22. A pressure roller 23 is advantageously positioned so as-to bear down upon the tape as it passes over the shaft 18.

In Figure 1 I have and 31. ring to Figure 3, it will be seen that the tape 11, upon entering the projecting device, passes toward the right across the aperture 30. At the tape-pulling and .rewinding I ii shaped that the tape will be accurately guided over the aperture 31 in its return passage through the projecting device. The tape then leaves the projecting device by passing over the guide roller or the like 33.

0 In Figure 5 I have illustrated a simple construe tion of the guide device 32. It is to be noted that it is substantially V-shaped and embodies a pair of angularly disposed rounded guiding surfaces 34 and 35. to each other and are respectively at substantially 45 to the axes of the apertures 30 and 31.

Referring again to Figure 1, it will be seen that the provision of two apertures in the foregoing manner results in the creation of two light beams 40 and 41 passing upwardly from the apertures 30 and 31 respectively. For projecting the light beam 40 onto the rear face of the screen 28, I provide an objective lens 42 mounted upon a suitable standard 43, and above this lens and behind the screen 28 I provide the two angularly disposed reflecting surfaces or mirrors 44 and 45.

For projecting the beam 41 onto the rear face of the screen 29, I provide first a mirror 46 which deflects the beam 41 rearwardly through an objective lens 4'7, after which a set of mirrors 48, 49, and 50 serve to direct the beam onto the screen 29.

In Figure 4 I have shown a practical embodiment of my invention. 51 represents a wall or partition separating a main room at the left from a private office at the right. For example, 52 may represent the desk in the private offlce. A suitable pedestal or stand 53 supports the ticker 54 and the projecting device 55, and apparatus of the character hereinbefore described in greater detail projects the markings not only upon the screen 56 mounted in the wall 51 and facing the room at the right of the wall, but also onto the screen 5'7 facing toward the left and displaying the markings toward the larger observation area.

While it is true that the markings projected upon the screen 56 (and upon the screen 29 of Figure 1) will be those which have already been projected upon the screen 5'7 (or upon the screen 28), this slight delay is not sufficient to outweigh the great advantages achieved by non-duplication of expensive apparatus. As a matter of fact, the amount by which the second screen displays are behind the displays of the first screen is extremely slight, as will be appreciated upon reference to Figure 3, wherein it is clear that the tape is guided in the most direct manner across the two apertures successively.

In Figure 5 I have illustrated a modification wherein the screens are differently positioned. Thus, I have shown a screen 58 positioned at the lower left and facing toward the right and deriving its beam of light 59 from the beam 60 emanating from the aperture 31. The beam 60 is directed onto the screen 58 through an objective lens 61 and by means of a pair of mirrors 62 and 63. Similarly, the beam 64 emanating from the aperture 30 is directed upwardly through a lens 65 onto a mirror 66 which projects the beam toward the right onto a screen 67. This modification illustrates the fact that from certain aspects my invention is independent of the particular arrangement of the two or more .1 screens that might be employed.

These surfaces are at substantially I do not wish to limit myself to the provision of two apertures, nor to the particular parallel arrangement herein illustrated, although such arrangement has proven to be highly satisfactory.

Furthermore, it will be obvious that changes in the details herein for the purpose of explaining the nature of my invention may be made by those skilled in the art without departing from the spirit and scope of the invention as expressed in the appended claims. It is therefore intended that these details be interpreted as illustrative, and not in a limiting sense.
