HEAT-DISTRIBUTING noon.
Application filed October 28, 1921. Serial No. 511,025.
To all whom it may 00mm; V
Be it known that I, FORD H.'Moo1m, a citizen of the United States, residing at Kansas City, in the, county of'Jackson and State of Missouri, have invented certain new and useful Improvements in Heat-Dis tributing Hoods; and I do declare the following'to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which-it appertains to make and use the same-reference being had to the accompanying drawthereon, which form a tion.
This invention relates to surface heater hoods and particularly to a hood to be used in connection with a heater for applying' heat to a surface such asasphalt and the like. In order to soften the asphalt for the road bed, it is usually the practice to apply heat over a relatively large area but to confine that heat within a given zone, and it isthe purpose of my invent-ion to provide an improved form of hood whereby an equal distribution of the heat may be maintained over a given area, so that there will be a uniform heat application to the asphaltum.
The novel construction of my invention Will be apparent by reference to the accompanying drawings, in which s Fig. 1 is a perspective view of a hood constructed in. accordance with my inven tion. r Fig. 2 is a vertical, longitudinal, sectional view through same, and Fig. 3 is a view of the heat, distributing baffles and casing protecting walls.
The casing or outer covering ofthe hood is in the form of a truncated pyramid, having inclined sides 1, 2, 3, and 4, bound at the-bottom by reenforcing members, such as strap iron and the like, as indicated at '5' and at the top by a flange 6,.reenforced by strap iron or similar material. 7 8, 9, and 10 are carried by the respective walls, whereby the hood may be supported,
from the machine supplying the heat. The upper portion of the hood adjacent to the inlet opening 11 is reenforced by cast iron plates 12, 13, and 14' at one'end and similar plates, generically designated 15, at the other end,'the plates being fastened to the ends and side walls so that the heated gases directed through 11 will not burn the hood Brackets covering, it being understood that the zone f within the hood is hottest at this Ipoint.
Since the bottom of the hood extends overheated, and the walls orplates '18 are inclined preferably. at a slightly greater 'anglc than the walls 1 and 3 of the hood so that there will be fiaring discharge ports 21 and 21' within the hood to direct the heated air over the pavement or surface .to belheated;
In order to direct the heated gairout;
w'ardly, the walls. 18 are providedwith inl 'clined, depending extensions 22 and 28,; as
will beclearly seen in Fig. 2. The edges of the plates 13 and 14 for the protector structures will lie "against the inclined edges of the plates or partitions 18, as seeninFig. 2, and thereby thoroughly protect both the end and side walls of the hood.
I prefer cast iron as a reenforcingplate for the reason that it best resists thej high temperatures and because it is'inexpensive to use in a, structure ofthis kind. I have. I
found in actual practice that the heat willbe be applied to the entire area confined within the bounds of the hoodp'The structure is inexpensive to manufacture and will eitiv ciently distribute the heat over the desired area.
directed through the central transverse open i ing 20 to impinge upon the surface tobe heated and that a uniform temperaturewill What I claim and desire to secure by Letters-Patent is:
A hood for paving machmes compris ing a casing in the form of a truncatedf pyramid, the top of which is provided with r a heat inlet opening,,inverted V-shaped par-f titions within the hood and adjacent to theopening to provide a central heat passage way, and two end heat passage ways t distribute the heat uniformly within the ooc J In testimony whereof 'I- affix my signature.
