- This invention relates more particularly to a log or means for recording theV tuning-in number of radio broad-casting stations.
4Owing to the large number of such broad-4 casting stations it is convenient that the log be made on a long strip of paper or other flexible material adapted to receive writing and the principal object of the invention is to provide an-improved mechanism whereby thestrip canbe causedto travel from one spool termediate surface to facilitate inscriptions thereon without creating tautness or slackness due to the fact that the diameter of the roll fao wheel on a scale larger 2 lookingto the left..
larger as 1t is transferred the other and conversely.
from the discloof paper becomes from one spool to Other objects will appear sure herein.
My improved mechanism contemplates means whereby either spool is directly driven independently of the other and the driving wheel automatically -or otherwise shifted from one driving position to the other by mere reversal of the motion' thereof.
The invention is e bodied in the example herein shown and described, the features of In the 'accompanying drawings-'- Figure 1 is a front view of a fraction of a case illustrating the logaccording to my invention.
Fig. 2 is a mechanism.
Fig. -3 is `a`section on elevation of the operating the line III-III Fig.
Fig. 4 is a view, on aflarger scale, partly in section and partly in full and broken out to illustrate the means whereby the drive wheel shaft is'shifted.
Fig.`5 is a sectional detail of4 the drive than shown in Fig. 2.
In the views 6"designates the case or cabinet in which the mechanism is suitably lov cated. Said case is provided with an opening exposing the tape on which the log is to be made.
Mounted on a suitablel frame 7 behind' or below the opening 6a is a pair of parallel spools8, 8a having shafts 9, 9, fixed with the heads thereof. Connected in an ordinary -translucent'glass 12 having its to -another across a-stationary hard inmoderately soft rubbe drive wheel thereon 1931. Serial No. 522,025.
manner with said shafts 9 and Q are the op# posite ends of Ka tape 10 so that the tape can be wound onto one spool from the other according to which spool is directly driven. The tape is passed over two smalllrounded bars or rollers 11, 11 between which is set in the frame 7-below the opening l6 a piece'- of face next said opening, ground to` helpprevent thertape from'slipping while receiving inscriptions. The shafts 8 and 8.a"of -the spools are each provided with knurled or otherwise roughened pinions 13 located indifferent parallel planes at rightangles to the axis ofsaid shafts, said pinions having tapered portions 13a leading to the rims thereof',`as shown..
Journaled i n the frame 7 is a drivinlgfshaft v14 having a driving y[wheel consisting 'ofl a r disk 15 clampedpby that the wheel bolts between smaller'metallc heads 16, said --drivingwheel being secured to the drive shaft 14 by a pin 17 or otherwise so shall rotate with the'shaft.
.One end. ofthe drive shaft lbeyond the frame h as secured to it a knurled wheel 14iLV .l1-5 by means of which the drive shaft and said can be turned'withthe fingers of va hand. The other end ofthe drive shaft is'cut out to form two annular grooves 18v and 19, the portion of the sha-ft 80- between said grooves being cnt with one or more grooves 20 correspondingly slanting as respects theshaft, said slantinggrooves -20 communicating with said grooves 18 and19." The thus grooved portion of said shaft turns g5 in a sleeve 16n fixed in or projecting outward from the frame 7; and threaded into a hole in said sleeve is a pin 21, the end of Jwhich enters said'grooves. When the drive shaft is turned-with the pin in either of vsaid annular grooves in a direction so that the pin 21 meets in an acute an le with the angular connecting groove the pin will pass the angular .groove but when turned in the opposite direction it will tend to enter saidv angular groove andl thereforc'bv a cam act-ionof the wall ofthe groove shift the shaft longitudi-v nally onits axis. Springs 22 and 22a are provided at .opposite sides of the frame tend- Y ing to urge the shaft into the slanting grooves 109 shaft, after-having the other spool to wind the tape on the other provided with a pair spool. The shifting of the drive shaft compresses the spring 22 and 22a at that side` toward which the shaft is shiftedl and relaXes it at the other.
The longitudinal shift of the shaft effected by the slanting groove is sufficient to cause the drivei wheel to shift from engagement with one of the pinions 13 tothe other without manual pressure, hence when the direction of rotation of the drive shaft is re- Only one the drive versed the shifting is automatic. of said pinions is directly driven by wheel.
' To prevent slippage or overthrow of the tape on the indirectly driven spool when the other is directly driven the frame 7 is provided with a small spring 24 for each of the spool shafts arranged to press on said shafts and engender enough friction to pre- 'vent such overthrow.
An electric light, as -indicated at 25, can be provided opposite the glass table for illuminating the tape so as to make the inscriptions or printing thereon easily visible in the dark.
The forms of the parts can be changed without departing from the gist of the invention as claimed.
1What I claim is: l
l. In means of the kind described for winding a tape froni'either of two spools onto the other, av longitudinally shiftable drive shaft having a drive wheel thereon to directly drive either one only of said spools, said drive shaft also provided with a pair of spaced annular restraining grooves connected by al cross groove and a iixed pin to enter said groove adapted tov effect Athe longitudinal shifting of said shaft when the rotation thereof is reversed.
2. In means of the kind described for winding a-tape from either of two spools onto the other, a longitudinally shiftable drive shaft having a drive wheel thereon to drive either one only of said spools, said drive shaft also of spaced annular grooves connected by a cross groove slanting to the axis of the shaft, and a fixed pin entering said groove adapted to effect the longitudinal shifting of said shaft when the rotation thereof is reversed.
3, In means of the kind described for winding a tape from either of two spools onto the other, a longitudinally shiftable drive shaft having a drive wheel thereon to drive either one only of said spools, said drive shaft also provided with a pair of spaced annular grooves connected by a cross groove, a iixed pin entering said groove, and oppositely operating springsvto urge said cross groove to engage said pin and cause the same to enter the opposite annular groove when the shaft is turned in one only of its two directions of rotation.
4. In means of the kind described for winding a tape from either of two spools onto the other, a longitudinally shiftable drive shaft provided with a drive wheel to drive either one only of said spools and provided with a pair of spaced annular guiding means connected with a slanting means, fixed means to engage said guiding means, said fixed means and said slanting guiding means adaptedto cause the shifting cross guiding of the shaft longitudinally from engagement of said lixed means with one of the annular .guiding meansinto engagement with the other annular guiding means when the rotations of the shaft is reversed.
