HOT AIR HEATER Filed Feb. 10, 1939 Inventor Attorneys Patented Apr. 2, 1940 umrso STAT-ES HOT. AIR HEATER; Robert M. Joyce, Grcenvillailviiss Application February 10, 1939, Serial No. 255,787 4 claims. (01. 263;-19)
My invention relates to a hot air heater for use with vertical type cotton driers, and important objects of the invention are to provide a hot air heater exhibiting simplicity, cheapness of construction, automatic operation, absence of moving parts, and absence of parts subject to wear and replacement, except for the refractory materials.
Other important objects and advantages of my invention will be apparent from a reading of the following description taken in connection with the drawing, wherein. for purposes of illustration I have set forth a preferred embodiment of my invention.
In the drawing:
Figure l is a general vertical longitudinal sectional view taken through the embodiment.
Figure 2 is a transverse vertical sectional view taken through Figure 1 approximately on the line 2,2 and looking toward the left in the direction of the arrows. v
Referring in detail to the drawing, the numeral generally designates a suitable masonry 01' other material base on which rests the elongated rectangular cross section metal housing 6 from one end of which rises the cylindrical metallic housing I which supports by connection at its middle the horizontal generally cylindrical housing 8. The housing 1 is coupled to the housing 8 by means generally designated by the numeral 9, While the bottom of the housing 8 is connected to the top of the housing I by coupling means generally designated by the numeral I 0.
The interior of the horizontal housing 6, the vertical housing 1, and the horizontal housing 8, all lined with refractory material such as fire brick l I, the end of the housing 6 in communication with the housing I having a curved refractory material wall !2 shaped to eliminate any air pocket at this point and properly guide the hot air and products of combustion smoothly from the housing 6 into the housing 1 in a concentrated vertical stream. Supported by the top wall of the housing 8 is a cast iron diffuser I3 which is supported by bolts or the like M and this has a convex face l5 whose axis is eccentric with respect to the axis of the housing 1, the axis of the difiuser being located slightly to the right as indicated in Figure l of the drawing, being positioned nearer the stack I6 which is in the shape ofan inverted funnel and has a flap or gate valve ll pivoted at one side thereof relative to the opening l8 adjacent the right hand end of the housing 8.
The left hand end of the housing 8 has coupled thereto the longitudinally outwardly tapering unhousing 8 as indicated by the numeral 22.
lined extension l9 coupled as indicated by the numeral'ZU, while the right hand end of the housing 8 has the longitudinally outwardly tapering unlined fitting 2! which is coupled to the A handle 23 is operatively connected with the gate valve IT for controlling the position thereof.
Spaced atapproximately equal distances from the top and bottom walls of the housing 15 and formed in the'right hand end of the 5 is the burner opening 24 through which is to extend the gas or .oil burner nozzle.
The fitting 2! is intended'to be the air inlet,
while the fitting I9 is intended to be the heated air outlet tothe cotton drier apparatus (not shown). The apparatus disclosed and described herein can efliciently be used with any standard type of cotton drier, and with such a type of drier as is shown in my co-pending application Serial No. 255,789, filed February 10, 1939, and entitled Cotton drying tower.
Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of my invention in the materials, to the precise structure and arrangement of parts set forth except as may be required by the subjoined claims. 7
Having described the invention, what is claimed as new is:
1. A hot air heater comprising a horizontal housing having a burner opening at one end and a vertical extension on the opposite end thereof, an elevated horizontal housing, the upper end of said vertical extension having communica tion with the bottom wall of said elevated horizontal housing at a point intermediate the ends of said elevated horizontal housing, an air intake at one end of said elevated horizontal housing, and a hot air discharge at the opposite end thereofj 2. A hot air heater comprising a horizontal housing having a burner opening at one end and a vertical extension on the opposite end thereof,
an elevated horizontal housing, the upper end of said vertical extension having communication with the bottom wall of said elevated horizontal housing at a point intermediate the ends of said elevatedhorizontal housing, an air intake at one end of said elevated horizontal housing, and a hot air discharge at the opposite end thereof, the interior elevated wall of said upper horizontal housing having a depending convex heat retaining diffuser in the path of thevproducts of combustion rising'from said vertical extension.
3. A hot air heater comprising a horizontal housing having a burner opening at one end and a vertical extension on the opposite end thereof, an elevated horizontal housing, the upper end of said vertical extension having communication with the bottom wall of said elevated horizontal housing at a point intermediate the ends of said elevated horizontal housing, an air intake at one end of said elevated horizontal housing, and a hot air discharge at the opposite end thereof, the interior elevated wall of said upper horizontal housing having a depending convex heat retaining diffuser in the path of the products of combustion rising from said vertical extension, said elevated horizontal housing having a damper equipped stack in communication with the interior thereof at a point between said diffuser and said. air intake.
4. A hot air heater comprising a horizontal housing having a burner opening at one end and a vertical extension on the opposite end thereof, an elevated horizontal housing, the upper end of said vertical extension having communication with the bottom wall of said elevated horizontal housing at a point intermediate the ends of said elevated horizontal housing, an air intake at one end of said elevated horizontal housing, and a hot air discharge at the opposite end thereof, a depending convex heat diffuser on the top interior wall of said elevated horizontal housing, said diffuser being located over the upper end of said vertical extension and position eccentrically with respect to the axis of said vertical extension so as to extend partially into the air intake area of said elevated horizontal housing.
