' ATTORNEY Patented June 23, 1936 UNITED STATES PATENT OFFICE 7 2,045,538 STOCK QUOTATION PROJECTING MACHINE Application October 16, 1931, Serial No. 569,128 Renewed August 8, 1934 13 Claims. (Cl. 178-42) This invention relates to stock quotation projecting machines in general and more especially to stock quotation projecting machines associated with high speed motor driven tickers.

Among the objects of the present invention, it is aimed to provide an'improved stock quotation projecting machine in which provision is made for causing the last printed quotation to be advanced intoprojecting position after the ticker comes to rest so that such last printed quotation will not be concealed from view for a period longer than the period required ordinarily for a' quotation to be advanced from the ticker to the light aperture.

It is still another object of the present invention to provide an improved stock quotation projecting machine in which the tape is caused continuously to be fed across the' light aperture during the ordinary trading hours and yet the portion of the tape at the printing position be maintained at rest during the impression interval.

Specifically this invention aims to provide an improved stock quotation projecting machine contemplating the use of a high speed motor driven ticker in which the tape is continuously fed across the light aperture at a uniform rate of speed and the portion of the tape passing the printing position during printing operation be intermittently advanced at a greater speed so as to permit the portion of the tape located at the printing position to be maintained at rest during the printing operation.

' These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompany- 1 ing drawings in which- 1 Figure 1 is a front elevation of a stock quota-1 tion projecting machine 0 the present invention;

a Fig. 2 is a fragmental side elevation of the same partly'in section;

Fig. 3 is an enlarged detail view in end elevation of the tape feed actuating mechanism;

Fig. 4 is a side elevation of ,the tape feed actuating' mechanism illustrated in Fig. 3 still further enlarged; andi v Fig. 5 is a. fragmental detail in end elevation of a part of the tape feed actuating mechanism 0 still further enlarged as compared to Fig. 4.-

In the embodiment illustrated, the ticker l is shown as typical of the high speed motor driven variety recently adopted by the New York Stock Exchange showing the tape supply 2 in dotted 55 line from which the tape T passes between the equipped according to type wheel 3 and the printing hammer 4 and then on to the initial tape feeding roller 5, then on to the second tape feeding roller 6, and then over the light aperture formed at the top of the extension 1 of the lamp housing 8 and then on to the rewind reel 9 mounted on the shaft I 0 journ'aled in the bearing II.

The shaft i0 is provided with a pulley i 2 which is connected by the spring belt l3, the pulley I 4 being mounted on the shaft l5 of the motor l6. 1 The type wheel 3, see Fig. 3 is associated with the type wheel stop unit i! made according to a standard high speed motor driven ticker which is operatively connected to the shaft l8 on which is mounted the type wheel gear IS in mesh with the motor pinion 20 mounted on the shaft 2| of the ticker motor 22. The motor pinion 20 also meshes with the main shaft gear 23 mounted on the shaft 24. I

The shaft 24 has mounted thereon the motor 20 control pinion 25 in mesh with the motor control gear 26 which, see Fig. 4, meshes with the driven gear 21, part of the attachment now to be described. Heretofore the secondary tape feed roller 6 was intermittently actuated. In the present embodiment, the intermittent actuating mechanism for this tape feeding roller 6 has been, omitted and in place thereof, the attachment now described substituted. 30

This attachment includes a horizontally ex.- tending shaft 28 on the end of which the'gear 21 is mounted. On the other end of such shaft,. there is provided the beveled gear 29 in meshwith the beveled gear 30 at the upper end of the 35 shaft 3|. At the lower end of the shaft 3|, there is formed the beveled gear 32 in mesh with the beveled gear 33 mounted on the horizontally extending shaft 34, at the other end of which is mounted the tape feeding roller 6.

By this connecting mechanism, the tape-feeding roller 6 will be continuously and uniformly operated whenever the motor 22 is operated. In addition to this continuous uniformly operating feeding roller 6, there is provided the feed roller 5 which is intermittently actuated, it being secured on the shaft 35 on which is mounted the clutch disk 36, the shaft 35 extending through the link 31, the upper end of which is pivotally connected to the. link as which in turn is pivotally connected to the crank 39 secured at its upper end to the shaft 40 which in turn has fixed thereon thefollower 4! provided with a cam roller 42 travelling in the cam groove 43 of the cam 5 -shaft24.

For pressing the tape T into friction engagement with the rollers 5 and 6, there are provided the pressure rollers 45 and 46 mounted on the brackets 41 and 48 respectively which are in turn pivotally mountedon the pivot pins 49 and 50 respectively, which brackets 41 and 48 are furthermore provided with the downward extensions 5i and 52 respectively which are connected by the spring 53 and 54 respectively resiliently to cause the pressure rollers 45 and 46 to press the tape T against the feed rollers 5 and 6 respectively.

The link 31 is provided with a recess 55 to receive the roller 56 resiliently urged against the inv clined face 51 of the recess 55 by the spring 58,

the roller 56 permitting the disk 36 freely to rotate with the feed roller 5 when the cam roller 42 is in the inner portion of the cam groove43 and the face 51 frictionally engaging the cam roller 56 to cause the disk 36 to rotate in the reverse direction when thevcam roller 42 rides in the outer portion of the cam groove 43. The cam 44 is so timed relative to the operation of the type wheel 3 that it will cause the tape T to advance the distance of a character and intervening space immediately before the printing action takes place.

This advancing action of the feed roller-5 will exceed in speed the advancing action of the feed roller 6 so as to cause the tape T to form a loop, see the dash and dot line 59 between the rollers 5 and 6 in Fig. 4, this slack 59 being sufficient so that if a printing interval ensues, the portion of the tape T at the printing location will be maintained at rest and the continuously operated tape feeding roller 6 merely take up the slack 59 to maintain the continuous, uniform advancing action of the tape toward the light aperture without exercising any undue pulling strain on the tape during the printing interval. The slack 59 thus forms a reservoir-or surplus to be drawn upon by the roller 6 during the printing impression. The cam 44 is mounted on the shaft 24 as aforesaid to be driven only during a printing cycle so that this slack 59 is only formed during the transmission of a character or series of characters forming a message. When the transmission of a message is completed and an interval elapses when no printing takes place, the roller 5 will be permitted to idle relative to the pressure roller 45 and the slack taken up in advance of the continuously operatedtape feeding roller 6 so that the roller 6 may advance the last printed quotation into the light aperture without delay so that the interval required for the last quotation to pass into the light aperture after the printing action comes to rest will merely equal the time ordinarily required for such quotation to pass from the ticker or printing location of the ticker to the light aperture.

It is of course obviousthat this intermittent feeding mechanism heretofore operatively connected to the cam 44 in advance of the type wheel 3 will be omitted and that the motion of the roller 5 is substantially identical with the motion of that intermittent feeding mechanism so omitted with the exception that the improved overrunning clutch consisting of the roller 56 in. the notch 55 will allow a free drawing of the tape.

As will appear from Figs. 1 and. 2, the light rays'from the lamp 60 in the lamp housing will pass through the condensers 6| and 62 to the deflector 63 from which they pass-up through the light aperture and tape to the objective lens contained in the housing 64 mounted in the bracket 65 extending from the upper end of the extension I. The light raysthen pass up to the deflector 66 by which they are deflected onto the deflector 61 and then deflected onto the screen 68 in the usual way. a

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.
