time between printing and projecting a givencharacter is reduced to a minimum, and whereby when the printer comes to rest the resulting delay in projecting the characters disposed on the portion of the tape situated between the printer and the projector will affect a minimum number of characters.

Specifically the invention still further contemplates the provision of an improved jump dissipating device embracing a bent or offset abutment and a finger for cooperating with such abutment to deflect the tape out of its path of movement between the printing mechanism and the projecting mechanism to form a loop and create sufiicient friction to iron out or dissipate the vibrations transmitted to the tape by the ticker. a

- Specifically the invention still further contemplates an improved combination of ticker having a positive type wheel, a jump dissipating device, a screen, and projecting means, whereby a minimum number of characters on the tape will be located between the ticker and the projecting means.

The invention still further aims to provide an improved combination of a ticker, projecting means, jump dissipating device, tape drawing means, and rewind reel, whereby the rewind reel will be effectively arrested against actuation when the ticker .is arrested.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of specific embodiments of the invention illustrated in the accompanying drawings in which Figure 1 is a fragmental end elevation of the improved combination;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 6 is a plan of the tape drawing device and rewind mechanism shown in Fig. 5;

Fig. 7 is a fragmental perspective of a positive type reel used with the combination illustrated inFigs.1and 2; and 1 Fig. 8 is a fragmental view illustrating the deflecting means used with a negative type reel.

In the embodiment illustrated there is provided a frame having a platform I on which ismounted the lamp housing .2 containing the 10 lamp 3, and having a lens 4 for receiving the light rays from the lamp 3 and projecting. it onto the deflector 5 preferably inclined as shown and mounted at the bottom of the extension 6, from which the light rays are projected upwardly to 16 the lens I forming the light aperture for the extensionli of the lamp housing.

To one side of the lamp housing there is formed abracket 8 for supporting the ticker 9, v which has a suitable printing mechanism in- 20 cluding the type wheels I0 and a feeding mechanism including the feed roller ll. On the bracket 8, there is also formed an arm I2 for supporting the ticker tape supply reel I3, the tape T passing from the supply reel l3 under the feed roller II and type wheels III in the directian of the movement of discharge of the tape T from the ticker 9 across the light aperture to the upper surface of the lens I, then over the guiderod l4 down to the tape drawing device including the driven roller l5 and idler I6, and from there under the finger ll of the lever I8 -to the rewind reel I9.

As shown in Fig. 2, the extension 6 is spaced a short distance from the guide 20 of the ticker just sufiicient to permit the lug 2| to cooperate with the tape and press it into engagement with the curved abutment 22 preferably secured to the side of the extension 6. The lug 2| is secured to a rod 23 which extends through the weight 4 bracket 24, which is pivoted to the arm 25, secured to the side of the extension 6. Between the weight bracket 24 and lug 2|, the rod 23 is preferably provided with a weight 26 which is adjustably secured thereto. The rod 23 is also adjustably connected to the weight bracket 24 as shown in Fig. 4.

By special reference to Figs. 2, 3 and 4, it will be seen that the upper surface of the abutment 22 is curved downward from the upper surface of the lens I, that is, at the edge of the light aperture formed by the lens I, and that the lug 2| has a tail piece which is adapted to press the tape T into engagement with such curved surface of the abutment 22 and deflect it out of its path of movement from the printing wheel to the lens 1 to form a loop and cause an extended area of the tape T to have both of its faces engaged, thereby creating an extended friction creating surface effectively to iron out any vibrations transmitted to the tape T by the ticker 9, that is, either by the type wheels H1 or feed roller When the type wheels l0 have positive characters formed thereon, as illustrated in Fig. '7, there can be used therewith an ordinary projecting lens mounted in the housing 21, which is supported by the bracket 28 extending from the upper end of the extension 6. With such lens, a single deflecting mirror 29 and screen 30 can be used. In the present instance, the mirror 29 is mounted in a housing 3| disposed at an angle to the screen 30, also mounted in said housing 3|, which housing 3| is preferably supported in place by brackets such as the bracket 32 connected to a wall or other support. With this combination, the type characters will of course appear negative on the tape, and when so appearing and the printed surface is facing up- .wardly as illustrated in Figs. 1 and 2, the light,

rays will project images of such negative characters to the projecting lens in the housing 21 where they will be inverted and projected to the mirror 29, which mirror 29 will deflect the characters on said screen 30 in its legible reading order.

As shown in Figs. 5 and 6, a motor 33 is there provided having a shaft 34 provided with a sheave 35, which is connected to the sheave 36 by the belt 31. The sheave 36 is mounted on the shaft 38 having aworm 39 in mesh with the worm wheel 40 mounted on the shaft 4| in the housing 42, which housing 42 is mounted on the platform 43 disposed below the platform I. The housing 42 has two bracket arms 44 and 45. The bracket arm 45 has a journal 46 to receive the shaft 41, on which the driven roller I5 is fixed. The shaft 41 is provided with a sheave 48 which is preferably connected to the sheave 49 on the shaft 4| by a belt such as a' spring belt 50. The arm 44 is likewise provided with'a journal 5| for theshaft 52, on which the reel 19 is fixed, which shaft 52 is provided with a sheave 53 which is connected to the sheave 54 on the shaft 4| by a slip belt such as a spring belt 55.

The arm 45 has pivotally connected thereto the bracket 56 to the upperrend of which is pivotally connected the idler 6 which serves to impinge the tape T in contact with the driven roller l5. The bracket 56 is also provided with a rod 51 having adjustably mounted thereon a weight 58, whereby the pressure to be exercised by the idler I6 may be controlled.

The reel I9 is preferably provided with a brake drum 59. From the arm 44 extends the arm 60 to which is pivotally connected the brake shoe 6| adapted to cooperate with the brake drum 59. The brake shoe 6| has extending therefrom the arm l8.

From the foregoing it will be seen that the tape passes from the tape drawing roller l5 and idler l6 down below the finger II to the reel l9, and that when the ticker is arrested, the rewind reel will continue to wind up the tape until the slack formed in the tape between the roller I5 and the reel l9 has been sufiiciently taken up to raise the finger l1 and therewith force the brake shoe 6| into engagement with the brake drum 59, whereupon the reel will be arrested and the spring belt 55 will slip relative to the sheave 53.

From the foregoing it will also be seen that by this arrangement, when the ticker operates, the driving roller I5 and reel l9, although both being operated from the same source of power, the roller |5 will exercise a uniform drawing action 5 on the tape T while the reel I9 due to its spring belt will slip relative to the driven rate of the motor 33 to compensate for the increasing speed transmitted to the tape by the increasing diameter of the reel, thereby ensuring a uniform 1o drawing action on the tape between the roller |5 and the finger 2|.

From the foregoing it will also be seen that the extended friction. creating surface afforded by the lug 2| will serve to interrupt the drawing 15 action exercised by the drawing roller l5 so that such drawing action will not be directly transmitted back to the ticker, thereby serving to protect the delicate parts of the ticker from injury by such drawing action.

When an additional mirror or deflector is provided as illustrated in Fig. 8, substantially the some combination aforesaid may be used with a negative type wheel. With a negative type wheel an additional inversion is required which will be 25 effected by introducing an additional mirror. In the embodiment illustrated in Fig. 8,. there is provided a screen housing 62 having a mirror 63 for initially receiving the images from the lens in the lens housing 21, from which mirror 63 the 30 images will be transmitted to the mirror 64 and from there to the screen 65.

It is obvious that various changes and modifi-' cations may be made to the details of construction without departing from the general spirit 36,

combination with a horizontally disposed light 50 aperture, of a tape puller for pulling the tape along said light aperture, an extended friction creating surface inclining downwardly from said light aperture at the anterior end thereof, and a finger having a tape engaging face conforming 65 to said friction creating surface for frictionally pressing the tape between the face of said friction creating surface and said finger.
