This invention relates to oil burning equipment _ abut against the flange 8 of venturi 2, and a
-admission to an air register through forward and
reduced terminal of said bolts is extended through
ring 6 and secured by nuts 9.
Secured to each of the doors 3 is an air direct

burning vessel is divided by a bulkhead into a
boiler compartment and an operators’ compart

.` Y
The surrounding wall of the air register in
' eluded in` this new oil burning equipment has
certain novel structural features which enable it
"i5 to possess side air admission control means that
are co-operative with other control means, also
of novel character, for rearwardly directed air
streams that _enter through the front of the
bolt .5, its purpose being to prevent air currents
from retardation by striking exposed bolts.
It is my purpose to provide means for opening,
closing and regulating the said series of dóors in
unison, as will appear hereinafter in the descrip
tion of the control means.
The sleeves 4 are extended forwardly beyond 15
the ring 'I and are there mounted on stub shafts
I2 and I2a which are secured to said ring, said
` boiler compartment, through the bulkhead, into
sleeves, near their forward end, having each a
centering arm I3 upon which is mounted a roller

being rotatably mounted on a hollow casting I1.

register having a front inlet „that admits rear

circumference of wall 39 the rods 31 are angled,

provided therefor in pistons 42, said pistons re
spectively being operable in cylindrical pockets
formed for their reception in a circular plate 43
that is rotatable in bearings about the casting i1.
A link 44 connects plate 43 with disk I6 and
serves to communicate motion from disk It to
said plate 43. Said link 44 carries a stud 4I
' that is engaged by guide members 4t on plate 43,
the outer end or said link having a slot 41 that
engages a pin 4I carried by the disk IS, a sta
tionary pin 49, which serves as a fulcrum for link
44, engaging in a slot 50 formedin disk i4, to
permit free movement of said disk.
Ii'rom- theîoregoing description it will appear
that the rotating motion of disk I6 is transmitted
through link 44 to member 43, to operate the
pistons 42 and thus the vanes I6, said operation
‘ imparting to said vanes a degree oi' opening com
mensurate with the degree of opening imparted
- to side doors 3, so that the ñow of air through
the register front occurs simultaneously with, and
in proportion to the inflow of vaix' through the
register wall.
In the slight reciprocating motion of pistons 42
a cushion of air wouldl occur in the cylindrical
pockets of plate 43, and to obviatesuch occur
rencev a vent 5| may be formed in the base of
said pockets.
I claimz-
Variations within the spirit and scope of my
invention are equally comprehended by the tore
going disclosure.
mg means to rotate said disk, a plate rotatably
mounted on said member and having radial pock
ets therein, pistons operable in said pockets, the
angled ends of said rods engaging said pistons,
and means operatively connecting said disk and
said rotatable plate to transmit movement from 16
said disk to said plate for the operation of said
pistons and vanes.'
2. The subject matter oi’ claim 1 in which the
movement transmitting means comprises a link
pivotally connected to said disk and to said ro
tatable plate, a stud carried by said link, and,
ñxed guide members on said rotatable plate with
which said stud is engaged.
3. An air register for use with furnaces having
a front wall with an opening therethrough, said
register including a series of equi-spaced bolts
extending out from the periphery of said opening,
sleeves rotatable on said bolts, segmental doors
carried by said sleeves and curved air stream
directing vanes carried by Said doors, arms ex
tending !rom said sleeves, a disk freely engaged
by the ends of said arms, a support 'on which said
disk is rotatively supported, and operating means
for rotating said disk.
4. The subject matter of claim 3, wherein said
sleeves and air stream directing vanes are con
nected to opposite faces of said doors and said
bolts are covered by plates for directing the air
past the bolts.
