AD. EITZEN TICKER PROTECTING MEANS Filed Feb. 7; 1929 Fa ker INVENTOR w ATTORNEY Patented Sept. 8; 1931 UNITED STATES PATENT OFFICE AUGUST D. EITZEN, OF NEW YORK, N. Y., ASSIGNOR T NEWS PROJECTION CORPORA- TION, OI NEW YORK, N. Y., A CORPORATION NEW YORK TIOKEB rnornerme Mme This'invention-relates to news printing tickers such as stock quotation tickers in general, and especially to stock'quotation projecting machines.

When news printing machines such as tickers and the like are used with wind-up reels for winding up the ta e as it is delivered by the ticker, or with stoc quotation rojectin machines where the tape is pulle throug. the projecting machine as it is delivered from the ticker, care must be exercised that the pull transmitted to the tape as it is delivered from the ticker is properly controlled so that the delicate mechanism of the ticker is not upset. In practice it has been found that if this pull is not properly controlled, a slight excess will be suflicient to disturb the proper alinement of the delicate parts of the ticker so that the type will not only print out of alinement but also print the wrong letter.

To this end it is one of the main objects of the present invention to provide means whereby the delicate mechanism of the ticker is positively protected from any such excessive pull.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of one embodiment thereof, illustrated in the accompanying drawings in which Figure 1 illustrates a ticker in outline equipped with the ticker protecting means;

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

Fig. 3 illustrates diagrammatically a tape puller and ticker associated with the ticker protecting means.

In the embodiment illustrated, the outline of a ticker 1 is shown in dash and dot lines having the stop plate or frame member 2 arm 10 terminating in a downwardly extending finger portion 11 registering with the re- As shown in Fig. 1, it will appear that when the tape T is being advanced b the ticker 1 to form aslack in front of the nger 11, such slack will be sufiicient to permit the contact end of the short arm 9 to clear the tape T and permit a tape puller P freely to pull the tape until such slack has been taken up. It will also appear that as soon as this slack has been taken up and the ticker 1 comes to rest, the tension on the tape T by the tape puller P in-the direction of the arrow 6, 6, will take up the slack in the tape T to engage the finger 11 of the lever 8 to raise the arm 10 and thereby depress the arm 9 and in turn cause the tape T at the point 12 to be tightly held between the end of the arm 9 and the discharging plate 3. Due to the increased length of the arm 10 as compared to the arm 9, this pressure will be sufliciently multiplied positively to anchor the tape T from being advanced b the tape puller P. In fact the relative lengt s of the arms 10 and 9 are preferably such that the pressure excrcised by the arm 9 will prevent the pulling of the tape T except by tearing or rupturing the tape T at the point 12. When the proortions are so adjusted, the delicate mechanism of the ticker 1 will of course be positively protected from injury by any excess tension exercised by the tape puller P.

It will also appear that the tape puller P will cooperate with the lever 8 to maintain the tape T taut in the projector R when the ticker is at rest and thus insure a smooth and even projection of the printed matter on the tape.

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.

I claim:

1. The combination with a ticker, of a tape puller for taking up the slack in the tape as it is delivered by the ticker, and means normally out of tension exercising position when slack is formed in the tape and operable for exercising tension on the tape as soon as the slack has been taken up to protect the ticker against injury. 1

2. The combination with a ticker, of a tape puller for taking up the tape as it is discharged by said ticker, and a lever normally riding freely on the tape and operable for exercising pressure on the tape when the slack has been taken up in the tape by said tape pullerto 'protect the ticker from excessive pulling tension.

3. The combination with a ticker, of a tape puller for taking up the slack in the tape as the tape is discharged by said ticker, an abutment, and a lever having a short arm and a long arm both adapted to engage the tape, the long arm cooperating with the tape to cause the short arm to impinge the tape against said abutment when the slack in the tape has been taken up by said tape puller.

4. The combination with a ticker, of a tape uller for drawing the tape as it is discharged y said ticker, an abutment, and a lever having two arms adapted to engage the tape the tension in the tape cooperating with one of said arms to cause the other of said arms to impinge the ta e against said abutment when the slack in t e tape has been taken up by said tape puller.

5. The combination with a ticker, of a tape puller, a discharge plate having a recess across which the tape passes as it is discharged by said ticker, and a lever having a short arm and a long arm both adapted to engage the tape, the long arm registering with said recess and being operative to cause said short arm to impinge the tape against said discharge plate when the slack in the tape has been ta en up by said tape puller to raise the tape out of said recess and thereby actuate said long arm.
