17 Claims.

The present invention relates to a drawing and observing device which can be used in general to observe and draw a tape or band along a guide rack for various purposes such as, for instance the drawing of a ticker tape having stock, bond or commodity quotations printed thereon. It is therefore an object of the invention to provide a means such as a desk or support for a work sheet along which the ticker tape is pulled under adjustable tension, the latter of which is suiiicient to carry the tape alongv a guide rack as it issues from the ticker or printing device. A further object of the invention is to provide means for adjusting the pulling or drawing tension on the tape as it is pulled along the rack by a motor. A still further object of the invention resides in the specific motor mounting, the details of the rack, the means for removably holding a Work sheet on the desk or support in cooperation with the guide rack for the tape and an oil cup for the motor.

Further objects will be apparent from the following description taken in connection with the accompanying drawings in which:

Fig. 6 is a sectional view of the oil cup. for the motor,

Fig. '7 is a plan View of a tape observing desk or support,

Fig. 8 is a side elevation of the desk of Fig. "I,y

Fig. 9 is a perspective view of a portion of the desk of Figs. 7 and 8, and

Fig. 10 is a perspective View of the sheet holder.

Figs. 7 and 8` illustrate the general layout of the desk or support II which is to be used with any conventional and well known quotation receiving and printing ticker I2. The ticker tape I3 issues from the ticker I2 as the tape is printedl and released and a prime mover or motor Ell draws` the tape along a guide rack I5 extending across the Width of the support II near the upper edge thereof.y The guide rack I5. has a curb portion I3 along one edge and a at runway or surface I'I at a slight angle relative to the horizontal,l Fig. 9. The rack I5 has a pin I8 near each end of the rack received in the curb portion I6 just above the suriace I1,

tol guide the tape flat. on the rack againstthe curb portion. Also the rack I5 has a support I9, at each end thereof tov provide a space under the rack which is for the purpose of wedging the spring holding clamps 2|, Fig. 10, which serve to hold a work sheet 22 on the support II.

The clamp 2| is composed of two

flat spring members

23, and 24 both of which are bowed and pivoted together by a pin or rivet 25. The arm portion 23 is longer than the finger portion 2-6 and isv adapted to extend under and against the under side of the rack I5 in the space 20 so that, as shown in Fig. 7, the end 2l is pressed against the support and the curved finger` ends or portions 28 contact4 the paper with pressure. In this manner, the paper sheet 22 is held in place on the support, II.

The support II also has a curb 29 along two side edges but these may be dispensed with if desired.

The prime mover or motor` I4, Figs. l and 2, is speed controlled by a governor 30 and can comprise any suitable type or construction, such as a well known electric motor fOr rotating the turn tables of talking machines. The motor I4 has a driven shaft 3l, driven by a helical gear 32, and a drive roller 33 is mounted on the outer end thereof. The roller 33 is secured on the shaft 3l by any suitable meansA and this shaft positively drives the roller 33 at a constant speed. A iiat ring-shaped disk 34 Fig. 3, is rotatably mounted onA the side of they motor and is guided by a boss portion 35, Fig. 1, securely mountedA on or forming a part of the frame of the motor and having a diameter which is just about equal to the diameter of the opening 36 in the disk 34 to provide a snug t. The disk 34 is held in place on the boss portion bya friction spring member 3l fastened by means of screws 38 to the boss portion.

The disk 34 is provided` with an inverted V- shaped frame 39, Figs. l and 3, welded or otherwise secured to the side of the disk 3 4 and this frame has slots 40 in opposite register in the opposite legs of the frame. These slots 40 guide and accommodate the bearing portions 4I, Fig. 1, on each end of a freely rotatable roller 42 which is an idler roller and rotates only when the tape I3A is. moved by the drive roller 33.. The function of the roller 42 which may have if desired a diameter which is approximately equal to the diameter of the drive roller 33, is to utilize its weight to force a frictional contact. between the drive roller 33, and the tape I3, whereby the latter will be pulled alongl the rack l5 asit is intermittently or otherwise released from the ticker I2. This idler roller 42 is adjustable from the full line position of Fig. 1 to the dot and dash line position 43 at right angles thereto by rotating the frame 39 and disk 34 on the boss 35. It will be observed that the maximum Weight of the roller 42 on the tape and thus on the roller 33 is attained when the idler roller 42 is above the drive roller 33 as shown in the full line position of Fig. 1 but upon rotating the disk 34 with frame 39 and roller 42 clockwise the pressure or force of the roller 42 on the tape I3 and roller 33 gradually decreases until it is practically zero at the horizontal position which is the dot and dash line position 43, Fig. 1, due to the fact that as the force on the tape I3 and roller 33 decreases the difference is made up by the frame gradually supporting more and more of the weight of the roller 42. In the dot and dash line position 43 the total weight of the roller 42 is carried by the frame 39. Therefore, by a simple adjustment of the frame 39 the frictlonal contact of the tape I3 on the drive roller 33 may be instantly increased or decreased but the increase should never be such that the drive roller 33 has a tendency to place too much tension on the tape I3 so that a space skipping during printing will occur in the ticker. Also, the

rollers

33 and 42 may be perfectly smooth or if desired the peripheral surfaces, particularly the drive roller 33, may be rough or coated with a friction material.

The motor I4 is removably and adjustably mounted on the side of the support II opposite the side on which the ticker I 2 is provided and for this purpose the motor has a flat plate or plates 44 welded or otherwise secured to a bracket 45, the latter of which is secured to any suitable part of the motor. These plates 44 are removably tted between a supporting disk 46 and a holding bar 41 the latter of which is fastened to the disk by means of screws 48, Fig. 2. The disk 46 has an elongated slot 49 with an enlarged portion 50, Fig. 2, at one end and extending circumferentially a suitable distance at a short distance from the peripheral edge. There is also a diametrical slot I extending a short distance from the peripheral edge of the disk and these slots 49, and 5I are for the purpose of adjustably and securely mounting the motor on the side of the support I I. For this purpose suitable screws, not shown, may be provided in the slots 49 and 5I which are secured in the sidev of the support II so that the motor and disk may be angularly adjusted to an extent governed by the length of the Slot 49. The disk 46 may, if desired, be secured to the support I I by means of screws, not shown, and this disk together with the motor may be rotated around a screw passing through the center perforation 48.

The motor I4 is also provided with a number of oil cups 49, Figs. 2 and 6, each of which is so designed that it can use up its entire oil supply. As shown in Fig. 6 the cylindrical container 50 is provided at the top with a screwthreaded closure cap 5I and a substantially horizontal outlet tube 52 near the top portion of the container by means of which the oil cup may be secured to the motor. An oil wick 53 passes through the tube 52 and then down through a branch tube 54 communicating with the tube 52 and terminating near the bottom of the container, the oil of course following the wick 53 by capillary attraction.

The apparatus operates as follows: Upon the start of a days stock, bond or commodity market session it is only necessary to start the motor I4 which runs continuously at a constant speed to draw the ticker tape I3 along the rack I5 as the tape s printed and released from the ticker I2. It may also be necessary to adjust the frame 39 and thereby the idler roller 42 between the extreme positions shown in Fig. 1 if it develops that the roller 33 imparts too much tension in the tape I3 thereby causing spaces to appear within a printed quotation on the tape. The paper sheet 22 is placed on the support II and the clamps 2I are slipped in place under the rack I5 whereby the spring members 26 by means of the nger ends 28 will maintain the sheet on the support. As the tape advances intermittently but slowly along the rack the quotations of a particular stock or a group of stocks are recorded manually on the sheet 22 in vertical or horizontal rows as may be desired so that each sale price as well as the volume for the particular stock may be instantly observed which will immediately inform the observer as to the trend of the market, not only in terms of price changes, but the activity or support or non-support which may be given by the stock buyers. When the ticker is not printing any quotations, the drive roller 33 merely rotates in contact with the stationary tape I3 and the latter in contact with and under the influence of the weight of the idler roller 42, that is such portion of the weight of the latter which is not supported by the frame 39.

It is, of course, obvious the invention is not limited to the exact combination shown and described since sub-combinations are also to be considered as a part of the invention as governed by the scope of the appended claims.
