w en -1 (B-138) (� ADJUSTMENTS GENERAL This bulletin contains requirements and adjusting procedures for the maintenance of Model 15 printers. Adjustments are arranged in a sequence that would be followed if a complete readjustment of a unit were undertaken. In following such a procedure, parts or assemblies which are removed to facilitate adjustment should not be replaced until all other adjustments are made which would be facilitated qv the removal of these parts. If one adjustment is changed, related adjustments should be checked because a change in one adjus t ment may affect related adjusbnents. These facts should be kept in mind when a single adjustment is to be made. The spring tension values given in this bulletin are scale reaaings Springs which should be obtained when Teletype scales are used as specified. which do not meet the requirements speci fied and for which no adjus ting proced ure is give n should be repla ced by n ew springs. Ordering information .lll8IY' be obtained from the Teletype parts bulle tin. en -.1 ,_,.,..,, I ' " Before proceeding to adjust any par t , read the descr iption of the a.cijustment carefully. After the adjustment is canple ted, be sure to tighten aey screws or n uts which I11BiY' have· been loosened. If a part that is 100unted on shims is to be dismantled, the nwnber of shims used at each of its mounting screws should be noted so that the same shim pUe-ups can be replaced when the part is re�munted • .... w -.1 Care should be exercised in removing or installing the cover to avoid damaging parts in close proximit;r. As a precaution, raise or lower the cover slo"fdy with a vertical movement. NOTEt In all figures of this bulletin, fixed pivot points are d esignated b7 solid black circles. l([SCELLANEOUS INSTRUCTIONS TO ADJUST MOTOR SPEED Synchronous motors do· not require governors because they ar e constant speed motors. The speed of a governed motor may be checked by viewing the tar get on the zootor governor through the vibrating shutters of a speed irrlicator ( tuning fork ) provided for t his purpose. · ( With the motor running and the target well illuminated, tap the speed indicator lig htly to make it vibrate and hold it so that the shutters are close to the eye. If the zootor is running at the correct speed, the target will appear stationary. If the motor speed is too fast, t he target will appear to be moving in the direction of rot ation; a.OO if too slow, in the opposite direction. NOTE: There is a possibility of setting the speed incorrectly, due to getting a speed multiple; i.e., the speed could be half the desired - 2- (B-13$) speed, or two-thirds the speed, or some other multiple, even though the s pots appeared to be stationary when viewed through the speed indicator s hutters. This should be kept in nd.nd if trouble is experienced in the o peration of the unit. Vfuen i ncr eas ing or decreasing the mo t or spe ed, the speed adjusting lever or the gove r no r adjusting bracket, respectively, should be momentari� dep r esse d.. See Figure 83 £or location of parts. TO MEASURE �EIVING RANGE llounted on the le.£t end of the main shaft of the printer is the range finder assembly which is used tor the purpose of orientating the selector tb the i ncoming signals. Before pr oc eeding to me as ur e th e rec eivi ng range on a unit equipped with a pu lling magnet selec tor, turn the selector armature s prin g adjusting screw to a position where it will require 6 to 6-3/8 ozs.* to stretch the arma ture spring to i ts position length . Then transmit RY (the letters R Y sent alternately) to the printer continually while the receiving range is being determined. The rang e m.q be taken as follows: (*) lf unit is equipped with a holding magnet selector, see Armature Lever Spring Tension Adjustment on Page 25. While RY is bei ng received, loose n the index arm thumb screw an:l shift the index arm o£ the range finder toward 0 unti l errors appear in the T hen move the arm back s lo wly untU errors no longer appear; at least copy. 72 characters should be received without error, This position indica tes one limit of the orientation range. Note the position of the index arm on the scale. Determine the opposite end of the receiving range by repeating the foregoing procedure with the index a rm near the opposite erli of the scale. After the two limits of the receiving range have been found, set the index arm ot the range scale midw81' between these two points. NOTEs en -.J 1'\) J>., v .... w CXJ lf facil ities for transmitting b iased test signals to the receiving unit are available, the index arm should be set at the optimum setting for the reception of biased signals. THE FOU.OWING PARAGRAPH APPLIES ONLY TO UNITS �UIPPED �w'ITH lULLING MAGNXI' SELECTatS CONNECTED DIRECTLY (NO LINE RELAY) INTO A LD�E CIRCUIT WITH BIASED SIGNALS. Tum the armature spring adjusting screw in a clockwise directicn untU errors a p pear in the copy. Then, from this point, count the number ot turns the adjusting screw can be turned in a counter-clockwise direction before errors again appear in t he c o py. Turn the adjusting screw backward (clockwis e) half' thie ttumber of' turns to a point midway betwee n the two tailing points, or the middle of the armature spring range, and lock the adjusting screw with its lock nut. If no errors appear in the copy throughout the .entire ra nge ot the spring, se t the spring te nsion at 6 to 6-3/8 ozs. a nd lock the adj u stin g screw. The orie ntation range should be rechecked after the armature s pring range has been determined. ;J - 3(B-138) ( TO SELECT A CHARACTER OR A FUNCTION '' When the text of any adjustment in this bulletin s pecifies the setting up of a certai n character or function, the following method should be used: Rotate the main shaft until the printing bail is in its extreme rear posi. tion. Hold the front edges of thos e vanes down which correspond with the MA.ttKING impulses of the combination (see Figure 1 for code chart o r code combinations) to be set up. Then rotate the main shaft in accordance wit h the instructions outlined in that particular adjustment.

Then mve the pull bar bail opposite the pull bar hwups. There should be .008" to .020• clearance between the humps on all pull bars (except the blank pull bar) and the pull bar bill. With the code bars moved to the lett position, there should be a like clearance between the blan k pull bar hump and the pull bar bail. NOTE: W hen checking this adjustment, all the pla;r of the pull bar bail should be taken up in a direction to make the clearance a minimum . To adjust, rEJno.ve the bell crank mountiag pJ ate assembly (Figure 16) from the type bar carriage assemb�, being careful oot to bend the bell crank retainers. Position the pull bar guide by means of its el ongated oounting holes to secure the specified clearance. * 'J * (A) These requirane nts should be checked with the- type bar carriage removed. {B) These requirements should be checked with the cype bar segment assembl3" removed from the type bar carriage. .� - 5- (B-138) ( INSTRUCTIONS FOR REMOVING THE CODE BAR! FROM THE CODE BAR ASSEMBLY If it becomes necessary to remove one or more code bars from the code bar assembly, the foll owing instructions should be followed carefully. Hold the inner nut on the code bar stop with a wrench and remove the outer nut. The inner nut may then be removed. In replacing the nuts, care must be used, as excess ive tightening of the nuts may cause the code bar separator collars to become embedded in the separator washers. Such a condition might prevent the code bars trom moving freely. To prevent this, tighten the inner nut slightly, just e mugh to fla+.ten the lock washer. Then, w:1. th a wrench, hol d the inne r nut in this position while tightening the outer nut. (See Figure 62 tor loca tion ot parts. � RIBBON FEm SHAFT BEARING PLATES ADJUSTMENT (Figures 6 and 7) See Note (A) The lett end of the ribbon teed shaft should be flush with the inner ertd ot the lett vertical feed shaft bevel gear teeth, when the ribbon teed shaft is in its left position and the lett vertical feed shaft bevel gear is held in engagement with the ribbon teed shaft gear. A like condition should m -.J ( ' .... � exist when the ribbon teed shaft is in its right position and the right verti cal teed shaft bevel gear is held in engagement with it. To adjust, loosen the munting screws of both right and lett ribbon spool, brackets and move the brackets upward as far as the elongated mounting holes will permit. Tighten the mounting screws with the brackets vertical, and at right angles to the casting. Adjust the right bearing plate by means of its clamping nuts to meet the first req�irement. Adjust the left bearing plate in a like manner, with the ribbon teed shaft in its right posi. tion, to meet the latter requirement. RIBOON FEED SHAFT DETENT SHUNG ADJUSTMENT (Figure 6) See Note (A) The ribbon feed shatt detent spring should be adjusted to meet the following two requirements: (.A.) The cent.er of the ribbon feed shaft detent roller should be at the same height as the center of the ribbon teed shaft, ai¥i the shaft detent should travel equally on either side ot the detent rol ler when the shaft is moved from. its extreme lett to its extreme right position or vice versa. (B) With the ribbon teed shaft in its extreme left position, hook a 32 oz. scale over the detent roller hub and pul.l horizontally toward the rear of the type bar carriage. It should require 19 to 23 ozs. to start the roller moving &WBN" from the detent. Also check this pressure with the shaft in its extreme right position. These two pressures should be within 2 ozs. ot being equa l. To adjust, loosen the m:>Unting screws of the ribbon teed shaf't detent To increase or decrease the spring pressure, remove the spring and bend. it. To equalize the pressure, position the spring spring ani position the spring. to right or left.
