separate electric-heating elements in the sep-
arate air spaces, said elements being remov-
able through one end of the drum, andmeans
to detachably fasten said elements separately
5- ,at the opposite end of the drum.
4..In an apparatus of the -class described,
a rotary drum having a central roasting
chamber, an annular series of separate elec-
tric heating' elements disposed about the
10 drum outside of said ,roasting chamber and
ranging longitudinally-of the drum, a shaft
on which said drum is mounted, and a com-
mutator on said shaft at one end connecting
conductor strips extending from the com-
15 mutator to the individual heating elements.
5. An apparatus of the class described in-,
cluding a casing, a drum mounted to turn in
said casing, and means to,'drive the drum,
said casing having an opening adjacent to
20 one end of the drum, near the bottom of the
latter, through which roasted material from
the drum may be discharged, a; receptacle in
the casing below the -drum for receiving
roasted material, and means constituting a,
25 chute and .slidably supported between the
said' receptacle and drum to be moved into
the casing or to an outer position for receiv-'
ing material from the drum and directing it
to said receptacle.
30 6. An apparatus of the class described in-
cluding a casing, a roasting drum mounted
to turn: in the casing, means to drive said
drum, said casing having a discharge open-
ing for the roasted material, a receptacle in
35 the casing below the drum to 'receive the
roasted material, a slide inounted in the cas-
ing between the drum and said receptacle,
and a tiltable chute carried by said slide to
move therewith- to a position for the chute
40 to lie within the casing or to an outer posi-
tion to receive material from the drum and
direct it into said receptacle.
7. An apparatus -of the class described in-
cluding a casing, a roasting drum mounted
45 to turn in the casing, means to drive said
drum, said casing having a discharge open-
ing for the roasted material, a receptacle in
the casing below thesdrumto receive the
roasted material, a slide mounted in thecasing between the drum and said receptacle, 50
And a tiltable chute carried by said slide to
move therewith to a position for the chute
to lie within the-casing or to an outer posi-
tion to receive material from the drum and
direct it into said receptacle, said chute in- 55
eluding a bottom member pivotally mounted
on the slide and an upstanding member hav-
ing an articulated connection with the bot-
tom member to assume different angular po-
sitions. 60
8. In an apparatus of the class described,
a roasting drum, drive means therefor, in-
cluding a drive shaft, a fan, connections be-
tween the fan and the casing, to exhaust
vapors from the latter, a shaft on which the 65
fan is mounted, driving connections between
the first shaft and the fan shaft, and a
clutch on the first-mentioned shaft, said
clutch including an element fixed con the
shaft, a sliding element, a spring acting on 70
said sliding element and normally tending to
maintain it in the clutching position, a shift-
ing fork to move the sliding clutch element
against the action of the spring, and a lever
fulcrumed at one end and pivotally. con-' 75
nected between its ends with said fork, said
lever being movable to a position to permit
the spring to engage the clutch element or
to a position locking the sliding clutch ele-
ment in the release position. 80
9. An apparatus of the class described, a
drive shaft, a fixed clutch element, a sliding
clutch element engageable with the first ele-
ment or disengageable therefrom, a spring
normally tending to maintain the sliding 85
clutch element in engaged position, a clutch
fork adapted to move the sliding clutch ele-
ment to disengaged position against the ac-
tion of said spring, and a lever fulcrumed at
one end and pivotally connected between its 90
ends with said fork, said lever being movable
to a position to permit the spring to engage
the clutch elements, or to a position approxi-
mately in line with the fork and acting to
lock the fork against movement under the 95
action of the spring.
