' TTTTTTT ckER Filed Jan. 8, 1929 2 Sheets-Sheet 2 NNNNNN OR ATTORN EY Patented Oct. 15, 1929 UNITED STATES PATENT OFFICE STOCK TICKER Application led January 8, 1929. .Serial No. 331,067.

This invention relates to printing mechanisms in which type bearing wheels are used, and more particularly to devices used in imprinting upon moving tapes, as stock tickers.

Such apparatus ordinarily includes mechanism for intermittently moving a tape susceptible of receiving imprints, a wheel bearing significant characters on its periphery, means to rotate the type wheel into predetermined positions relative to selected characters, means for moving the wheel in the manner of a shuttle towards and from the tape, and means for supplying ink to the type on the wheel.

The tape, usually paper, thus receives imprints on one side only from the wheel, at more or less regularly spaced intervals and obviously if alphabetical characters are used, the words, spelled out in full, occupy a considerable length of the tape in order to convey any desired information, while speed, in the production of a message, is not possible to attain.

The present invention includes important improvements, one of which is the substitution of a fieXible, transparent tape of far greater strength than paper, the substance preferred being celluloid, which can be used an indefinite number of times by cleaning,

3o by automatic or other means, the inscriptions from its surfaces after each use.

A further feature is in the provision of two wheels arranged in opposed peripheral relation., one bearing alphabetical and/or numerical characters, and the other a series of symbols of unlike nature, as shown in the drawings herewith, and having significant values in accordance with a code or chart used in connection therewith.

Another purpose is in the production of a device which will imprint upon opposite sides of a tape simultaneously any desired combination of letters and symbols in preferred arrangement, so that when the tape is exposed in its passage, with a lighting means on one side, the inscription may be easily read by an observer or a group of persons interested therein.

These several objects are attained by the novel means hereinafter described and illustrated in the accompanying drawing, forming a material part hereof, and in which Figure 1 is a front view of type carrying wheels as arranged in accordance with the invention. y

Figure 2 is an enlarged fragmentary view of the same, showing them as slightly separated to permit the passage of a tape.

Figure 3 is a plan view of a section 0f printed tape.

Figure 4 is a view showing how a letter of the alphabet can be used with a set of symbols and also a special set of additional symbols which can be utilized to indicate words used frequently on tickers such as money- G5 "lost-found"-preferred-"A stock- B stock, etc., etc.

In the present showing, Figure l, which is largely diagrammatic, a pair of type wheels 5 and 6 are indicated as being fixed upon shafts 7 and 8, each of which is rotatable by means commonly employed to bring any desired type character into position to print on a tape 11.

The wheels are provided with ink supplying devices 9 and 10 the shafts of which, to-

gether with the shafts 7 and 8 are so mounted as to move slightly towards the film in the act of making impressions and away thereafter during their rotational period. 2o

Each of the wheels carry raised type, the upper having preferably a complete alphabet of twenty-six Arabie characters and ten numerals, as usually employed, and the lower wheel 6 having twenty siX symbols, each hav- S5 ing a significance which will be well understood by the persons interested in the device, these symbols representing stock or like values and certain other matters relating to stock selling or buying.

Obviously when the wheels are brought to make intimate Contact on opposite sides of the tape, both characters, which have been previously brought into printing position, will become imprinted on the tape, one on the face and the other on the back, and in any predetermined position relative to each other.

The specimen of tape, shown in Figure 3, indicates at the left a character H on one side and over it a on the other side imprinted WU by the lower wheel, as is also the numeral 42; next adjacent is the letter N, printed by the upper Wheel on the face of the tape and a symbol thereover, but on the back, followed by other numerals including a fraction.

Further on an alphabetical character H appears in connection with Athe same symbol as is displayed over the N.

From the foregoing it will be seen that any combination of characters and symbols may be imprinted on the tape and as many of these are applied simultaneously, much valuable time Inay be saved.

Having thus described the invention and set forth the manner of its construction and application in a manner which will be readily understood by persons familiar with .the

' art, what is claimed as new and sought to secure by Letters Patent, is :H Y

1. A tape printing apparatus compris-'ng two type carrying wheels, relatively upper and lower, one of ,said wheels having alphabetical and .numerical Characters on its periphery and the other a series of signicant symbols, and a tape movable between said wheels to receive impressions from each simultaneously upon opposite sides.

v2. A tape printing apparatus .ceniprising a pair of wheels mounted to be moved into peripheral occlusion, one Aof said v,wheels hav-ing letters .of .the alphabet and numerals raised from its peripheral surface, .the other wheel having a series of symbols including numerals, :and a exrble'transpanent tape 4nuova'ble between the :printing points of said wheels.

3. A tape printing apparait-uscomprising a V pali-r of wheels mounted to be moved ilimitedly towards and from each other, raised ai'phabetieal and numerical :type .on the :periphery of one wheel,-.thev other Wheel .bearingsymbols rel-ating i-n yseine manner to the alphabetical characters, vafnd a :tape-off translucent material lrif-lovable transversely between said Wheels the plane of their axes.
