AUTOMATXG, TOASTER MODEL T~_
The Model~ T9 Sunbeam Silent Automatic Toaster differs from pwevioUs Sunbeam toasters in design and in the addition of a selective "po.~-up" feature by
which the toast may be made either to rise automatically or to remain inside
the~toaster at the end of the toas$ing period by the setting of a control knob. The thermostat timing mec~mnism is so arranged that it will toast
bre .ad..~.t,.o .the same reasonably uniform degree of brownness whether the toaster is hot or cold. No toaster, however, will automatlc’~lly and effectively compensate for voltage fluctuations or for considerable differences in
bread (as between whole wheat and white bread, or fresh and dry bread), but such variations can be taken care of by a change in thin set.ring of .the
Bakelite adjustment knob on the side of the Sunbeam Toaster. For large voltage variations a second adjustment can be made readily as described in-
the Toaster instruction booklet, (one of these booklets is attached to next
page) and as explained in Section 3N-3 of this bulletin.

HOW TO SERVICE MODEL ~T9 SUNBEAM AUTOMATIC TOASTER
Plug toaster co~d into electric power circuit of same’ voltage as that marked
on name plate at bottom of toaster. The electric power circuih must have sufficient capacity fdr ~upplying the Toaster with.the wattage it require~
list attached to this bulletin)..is lowered the switch closes, all elements .. will heat to a cherry red .color, ~nd the signal light wil.! glow. ’ ’ ¯
The main thermostat blade (key number 47) is heated by the ’thermostat heater element (5), the heat is reflected to the thermostat by the reflector (3) and the amount of ~heat reaching the thermostat blade is 96gulated by moving
this reflector through the cam (13) ’turned by t~e thermostat adjustment"
knob (24). The temperature at which the thermostat snaps off is regulate~ by the tension of the coiled spring (48) which can be adjusted byturning. the nut (49A). The thermostat blade will snap with a ’~61ick" against the
flat s.urface of its supporting casting. But before it reaches this surface
the thermostat blade hits the end of lever (33) which opens the switch and
if the ’control (2~D) is set to "pop-up" the toast ra~k will move up, coming
to a slow stop. The cushioning cylinder (56A) dampens the action of the
"pop-up" spring. If the control k~ob (24D) is inthe position marked "Keeps
Toast Warm", the movable handle (15) must be raised by hand to remove the toast. The thermostat blade (~7) cools rapidly and snaps back into its orig-
inal position with a second "click" a few seconds after the flrst~ thus re­setting the thermostat, The ~ext toast must not be started until after this
second click. The auxili~-~ t-~e ~rmos-~at ~ compensates for the temperature rise in the metal parts of the toaster~ Without the auxiliary thermostat,
the toast would tend to become lighter as successive slices, were made.

To remove control knobs (2~ and 2AD) and cams (13 and 22), remove hexagon nuts (2AA),’lock washers (2&B) and tension washers (2&C).
To ~emove toaster heating element assemblies (6,
in ~del T9 Sunbeam Toasters are graded and matched for resistance value.
To obtain uniform toast all of the elements used in a toaster must have the sam___~erag~_~number, l, 2, 3, ~ or 5, stamped on the upper metal border of the
element and this same number must also appear on the thermostat heater element
(see Section 2L). Before removing the toasting elements, remove the sixteen
guide wires (19 & 20). Lift the wires out of holes with a small hook or bent
wire. Do not stretch the wires more than necessary in removing or the may lose their tension. Keep the eight longer center guide wires separate from the eight shorter ones ~o avoid confusion later in reassembling. R~-

3. Assembling Model T~ Toaster’-’
3-A.
To fit toasting elements (6, 7, 8) into element frame. (1), make sure that all elements used have the same grade number stamped on the upper metal border
(see Section 2-G). For correct electrical connections, refer to the wiring diagram on page 1 of this bulletin. (When repairing 200 to 250 volt toasters
observe bus-bar connections before taking apart. Elements on such toasters
are connected in series so that bus-bar connections are not made as indicated
below:) Fix elements in place by fastening terminal screws on bus-bar as tightly as possible to prevent loo°sening in operation of the toaster and poet
electrical contact. On llO-120 volt (and 125-130 volt) toasters% bus-bar (26) connects terminal stud (30) to thermostat heating element (5). Bus-bar (25)
connects other end of the thermostat heating element to left end of front t6asting element and to right end of center toasting element (7). Bus-ba~.
(2~) connects right ends of front and rear toasting elements (6 & 8)., B~s~bar
(27) connects left ends of rear and Center toasting elements. Bus-~’ (~) is
Page 6
permanently riveted to one fixed switch contact point and connects it to left end of center element:.~(7) and fixed bus-bar~ (1B) connects other ~wltch con-
tact to terminal stud, thus completing the circuit ~s shown on the wiring dia-
gram.
3-B ~
To fit top for element frame (18), put six porcelain insulators (59) in posi­tion on frame (1) and fit top (18) in position by ~bending ears over lugs on
element frame. (See note under Key No. 18 on parts list). Be sure that top is firmly held incorrect position.
3-C.
Guide wires (19 & 20). - The long (19) and short (20) guide wires may be re­placed, long ones in the center, by first hooking the 16wer.ends to the open-.
ings in small lugs on the bottom of the ~lement frame and then pulling the
t~p loops up with a small hook to engage the openings in the element frame
to.~. (.i8.). ..........................................

Bottom Mounting.Plate Assembly (Ii). Before assembling the bottom mounting plate to the toaster, the adjusting cam for reflector (13) and the ejector cam (22) should be ass~embled to their respective bearings. The order of as-
sembly for each one is as follmws: Control Knob (2~), spring, tension washer (2~C), bearing cam lock washer (2~B) and hexagon nut (2~A). Then place the
bottom mounting plate assembly under the
~
element frame (1) so that .the pre-.. !
Jecting lugs. of element frame enter corresponding slots in the mounting plate. Twist .the lugs Just enough to insure a ~ e~n~a~e.ment~ between the element
frame and mounting plate. ~ ~, .... ; ¯
3-E,
The reflector (3) for the thermostat heating ass.embly is mounted on t~e element
frame assembly by inserting reflector pin (~) through the bracket, openings and hinge in the back of the reflector. Projection o.n.top of ~eflector should be
outside, not under, reflector spring (31). Flatten end of. pin (~) so that it will not fall out. Turn the cam adjustment knob (2~), observing whether the reflector moves freely. Movement of the reflectbr changes the amount of heat being reflected to the thermostat b~ade (~7). ~For light toast the angle @f.o ~ i
the reflec.tor is such that a maxim~ um amount of heat is reflected from the
~
. thermostat h~ating element (5) to the thermostat blade (~7), This causes the
..0
thermostat to snap off sooner."

3-F.- Ejecto~ Pawl and Ejector Release Pawl (~8). - Two pawls are assembled on the
same stud in the element frame assembly (1). The lower pawl is operate~ by
the ejector cam (22) which !s turned by the control knob (2~D). ~ Atension
spring (29) fits about the pivoting stud and a~plies pressure-o~
Make certain that this spring fits properly
3-G. Upper and Lo~er Shaft Assemblies (9 & 10) and Rack Asse.m~ly:(56). - The upper
.~ and lower shafts and the rack assembly. (56) should be assembled at the same
time. Insert the br.ead-carrying racks carefully through, the lower ends of the slots at the bottom o~the element frame (1) from the reflector end~of
the element frame assembly. The upper parallel bars should be swung over ~the top of the ~toaster and sprung apart where necessary to bring them to their ap-
proximate location at the ejector end of the toaster. The lower parallel bars are easily located after the rack is in its position i~ the toasting chamber.
The ~end .of the upper shaft assembly~(9) is inserted through the ~pen~n~s in
side of the element frame which serve as bearings for the shaft. The ejector
lever (35) is placed so that it can engage with the ejector pawl (58). The
switch roller assembly is raised so that the bracket engages the rack assembly in the correct manner. The cushioning cylinder (56A) is fitted over the pis-,

i~ii~ . between:the notched projections on’switbh lever (36) and slot in the ele-
ment ’frame (1) directly behind the’upper shaft. The ejector spring (21) is fitted between the adjusting screw (32) projecting through a slot’in:
I
the bottom mo6nting plate (ll) and the top of ejector lever (35).’ Tofit
this spring, remove the .adjustment nut (21A)from adjusting screw (32) .and
loop the end of the spring (21) through the screw. Lower this through the
slot in the mounting plate and fit adjustment nut (21A)~ With the end of a small screw drlver~. raise the other end of the spring to the hole in the ejector lever (35).
3-I. Switch Locking Lever (3~)~ - The switch lockihg l~ver (33) may be replaced
.as follows: Torsion spring (33A) should be fitted about pivoting pin so’
that the switch lever (33) moves downward inside switch arm (36A). ’ Insert the pivoting pin of the lever into its proper location on the.underside 5f
the bottom mounting plate. Bend the lugs with th~ bearing holes up to nor­mal position to locate the locking lever. ’When the plastic bas.e (16).’has.
been put on .the mounting plate, examine the Switch locking lever for clear-
ance with the thermostat blade (~7)’ at the reflector end of the toaster, It is important that the switch locking lever be from 3/6~: t6 3/32 inch a-
bove the top of the casting uoon which the thermostat blade is mounted. This is checked after fitting plastic base (16).by inserting gauge T20~9i-l:
in position where thermostat bracket (50) fits. Theend of the lever should enter but not pass the step i~ the gauge. The test should be made with mov-
¯ "able

3.-K.o. feature .of the toaster~ Turn the control knob (2~D) to the right (Keeps .
toast warm) as far as’it will go; this action permits torsion spring (29) to move a pawl into engagement with the ejector lever (35), when the toaster
rack (56) is lowered.. When the toaster rack is raised again to its starting position, the lever remains in engagement with the pawl. When the control
knob (2~D) is turned.~.~o the left (pops toast up) the ejector lever is leased by the ejector release pawl, (58)o The extension spriAg (21) which has been placed under tension on first lowering the rack assembly (56), ~op­orates on the ejector lever (35) through shaft’to raise the rack. During
the toasting operation, control is effected from the thermostat through the
switch locking lever assembly (33), switch arm (36A), and ejector pawl (58)
which controls movement of the ejector, lever(35), Be sure that the tor-
sion spring. (29) fitting about ejector pawl stud (58.)_ applie_s_ tension.ta .....
TO check operation of the toaster when the control knob (2~D)is in the "pop­up" position., lay the toaster on its side so as to take the weight’ off th~ switch locking lever (33), Lower the rack assembly,(56).
".
The switch’arm (36A) should engage the switch locking lever (33). Lift the end of the..: switch locking lever which makes contact with the thermostat. The rack as-
sembl~ should move up on the release of the switch .arm (36A) and.ejector lever (35). The movement is dampened by cushioning cylinder and piston.(63)
and rack should not slap against top of. slots in element .~frame (1).
3-L. Fr.ont,’Center and Rear Sections of Body.(52,~O, S1), - ~en assembling the
.body to the toaster, the front and rear covers should be put on first, tak-
ing care that the.front section with glass signal disc (52A)01s.located in front of the. signal element (57).. Use screws ’(~i). in fastening the bodies tothe toaster. The stationary handle (39) is attached to the center sec-
.hio.n by two screws (39A). The center section (~O) may now be slipped into
pla.ce over the top of the toaster, with .the projecting armfor the movable handle through the slot in the center body..¯ ’The movable handle (15) is at-
. tached by set screw (15A) to lever projecting from the side of the toaster,

3-N1.Adjustment of Thermostat. - The thermostat.may be adjusted for. correcttoast-
ing with the two alzbratzng weights (Tool No, 2 & No, 3). All thermostat adjustments should be conducted in a room at temperature of 75 to 80 degrees
C ¯
Fahrenheit, The bottom cover and thermostat bracket assembly (50) is placed
on a flat table, Be sure that all thermostat parts are at room temperature, Place the rubber bumper of small weight (Tool No, 3 - 1.85 Lbs.) upon the cen­ter of tharmost.at blade (47) directly opposite thermostat, stop (&3), but be
sure that the stop does not interfere. With a fing6r, depress the thermo-
Page 9
star blade to its down position as the smaller weight wiil be insufficient
to cause the¯ blade to snap down~. With Tool No, ~, turn set. scr.ew .for
auxiliary the~o~ta~ adjustment (55) to the right against the lip.on thermo­stat blade (~7). Then carefully balance the smaller weight so that it rests
in a perpendicular posit.ion on the center of blade. Hold weight by means of. sliding collar on rod,.’:~Continu6 to tighten set screw (55) until .the thermo-~ i.
stat blade (~7) acquir~~ just enough tensi6n to force the blade up. with the snmll weight restingoin the middle. If the weight should rise without the set
screw (55) touching end of main thermostat blade, replace the main th.er­mostat blade (~7).. This setting may be accurately determined by: sliding the..
collar up and. down the rod. The weight plus the friction., f~Sm the colla..r
slidin~ db’wn should suffice to keep the blade down, but the~.weight minus the
friction f~om collar, sliding u_~ should allow the thermostat to snap up. A few .trials will soon give the¯operator, the proper "feel" for hap. dling weight

After adjusting auxiliary thermostat adjustment Screw (55). as, explained a-
bove,"the Tool No, 2heavier weight (2 ibs) is placed on the rod on top of
the smaller weights. Bothweights are then placed in the center of main
