The de?ector- H is pro'vided’at its center with

Another feature of theinvention resides in
15 the novel means provided for yieldably retaining
the‘ element It of the de?ector in frictional en
gagement with the conical bearing surface it,
whereby the de?ector may be conveniently ro
tated from one position to another to control the
20 directional ?ow of the air from the heater, and
the de?ector to be readily and conveniently ro
tated to‘ any desired-position. The construction
that it may be rotated in any- direction desired,
and the degree of rotation in either direction is
erence to Figures 1 and 2. The de?ector may be
quickly assembled on the bearing it of the heater
by simply ?tting the member l8 of the de?ector
onto the seat i3 and then operatively connecting
the hook 216 of the element 25 to the cross mem
ber or pin 27 of the ?nger knob M, as shown in
_ Figure l.
