I, FRANK HENRY VAN HOUTEN, residing at Matteawan, in the County of
Dutchess, and State of New York, in the United States of America, Machinist,
do hereby declare the nature of this invention, and in what manner the same is
to be performed, to be particularly described & ascertained in & by the following
statement:
This invention relates to reflector lights for baker's ovens; and it consists in the
construction and novel combination of parts, as hereinafter set forth & pointed out
in the claims.
The object of the invention is to provide in connection with a baker's oven, a
reflector light which can be readily turned to illuminate the interior of the oven
when required & when not needed can be easily turned outward therefrom, the
opening in the oven wall being closed whether the light be turned outward or
toward the interior; and further, to provide a cut-off cock, that when the reflector
light is turned outward the cut-off cock will cut the gas down to as small a flame
as may be desired.
In the accompanying drawing, A, A, designates the outer case, which is usually
made with the side walls, B, B, somewhat converging so that it will closely fit a
tapering opening in the oven wall at the side of the main door. The interior
portion of the case is provided with bearings, C', C', for the journals of a revolving
semi-cylindrical door or cut-off, D, which is provided in its concavity with a
projecting hook or catch, E. This revolving door is, also, provided with a pivoted
handle, F, which is designed to extend outward beyond the oven wall, and serves
to enable the operator to turn said door with facility. G, indicates the jet carrying
frame. G¹, indicates the mica in front of the lantern.
H, is the burner which is provided with a main channel, a, and a smaller
auxiliary channel, b, the latter channel, b, being provided with a regulating
screw, e, by which to regulate the supply of gas that flows through auxiliary
channel, b, or to entirely cut off the flow of gas to the burner, as may be desired.
A length of flexible tubing, L, extends from the burner to the gas supply. R, is
the concave reflector which is attached to the solid back portion, N, of the lantern
by means of suitable hooks or supports, P. In the back wall of the lantern
is provided a vertical slot or bearing which is adapted to engage the hook or

page_text: catch, E, of the revolving door. When the revolving door is turned to rotate
the lantern outward, the latter can be readily detached from the door for cleaning
or other purposes.
.
Vertical shoulders or bearings, V, are designed when the lantern is in position
& attached to the hook or catch to engage the sides of the revolving door so that
the lantern will be held in a firm & steady nianner. At the upper end of the
case, A, I provide a bracket, A', which forms the bearing, C, for the upper journal
of the revolving semi-cylindrical door. This bracket, A', is open & permits the
ready removal. of the upper journal-therefrom.
The lower journal of the semi-cylindrical door. is in a bearing attached to the
bottom plate of the oven. 'An arm, X, depends from the tube, X', of the main
channel, a, & enters the slot, Y, in the slotted guide plate, Z, so that when the
reflector is revolved, the arm, X, will move in the slot, Y, & either turn the gas on
or off as desired. A spring, W₁, is provided at each end with a curved stop, W³,
& is securely riveted intermediate of its ends to the interior of the case, A, near the
upper end of the latter. These hooks or curved straps, W², engage a vertically
projecting pin, W³, at one side of the revolving door on the top of the same and
holds said revolving door either in the open or closed position as may be desired.
The slotted guide plate, Z, serves to guide the arm, X, & also serves to support the
revolving frame at the bottom:
By removing that portion of the revolving frame that carries the burner,
& reflector, the remaining portion may be removed & lifted clear of, the bearing
in the bottom plate & be removed entirely from the stationary frame.
Having now particularly described & ascertained the nature of my invention
& in what manner the same is to be performed, I declare that what I claim is,
1. The combination with the case & the revolving.cut-off of the burner mounted
thereon, having the gas supply pipe provided with main & auxiliary channels & the
regulating screw in its auxiliary, channel, the slotted guide plate attached to the
casing, the cock in the main channel of the supply pipe & the arm depending from
the cock & engaging the slotted guide plate, substantially as specified.
2. The combination with the case & the revolving cut-off provided with the pin
& the spring having recesses engaging the pin, the spring being secured to the case,
substantially as specified.
3. The combination with the case & the revolving cut-off having the lever, F, of
the burner, the supply tube leading to the burner, having the main & auxiliary
channels, the slotted plate, attached to the casing, the cock in the main channel
& the arm depending from the said cock, substantially as specified..
