HEATER.
Application filed February 18, 1923., Serial No. 619,474
To all whom it may concern Be it known that I, GHARLns F. Lorine, a citizen of the United States, residing at Tonopah, in the county ofNye and State of Nevada, have invented certain new and useful Improvements in; Heaters, of which the following is a specification.
This invention relates to heaters, and more particularly to electric heaters.
An object. of the invention is to provide an electric heater having a casing through which air willreadily flow by natural draft.
A further object is theprovision of a pair of inlets, one of which is connected to an outside fresh air supply.
A further object is the provision of a heater having a casing with.heatingelements arranged therein and baflle plates disposed in the path, of the flow of air to cause the air to be brought into contact with the heating elements.
A furthen object of the invention is the provision of a wedge-shaped casing larger at'the topor outlet endfthan at the bottom or inlet end.
In the accompanying drawings, I have shown one embodiment of the invention. In this showing:
Figure 1 is a side elevation, Figure 2 is a front elevation, Figure 3 is a top plan view, Figure 45 is a perspective view of the lower portion showing the method of'constructing the casing,
Figure 5 is a vertical sectional view on line 55 of Figure 2,
Figure 6 is a similar view on line 6 6of Figure 1,
Figure 7 is a horizontalsectionalview on line 77 of Figure 5, and,
Figure 8 is a similar view on line 8-8 of Figure 5.
Referring to the drawings, the reference numeral 1 designates a hollow base or support having an inlet opening 2 communicating with the room to be heated. This opening is controlled by a sliding damper 3, mounted in suitable guides or tracks 4. Op posite the inlet 2, there is provided a second fresh air inlet 5, having a pipe 6 extending therefrom. The pipe 6 is adapted to receive a flexible conduit, which extends to the exterior of the building to supply fresh air. The top of the base is provided with an opening 7 and the material forming the top is bent upwardly adjacent this openthe interior of the casing. Handles 15 are secured to the side walls adjacent the top to permit the heater to be moved to any desired position.
The heating elements are arranged vertically and centrally of the casing. As shown, they are supported on transverse members 16, formed of suitable insulating material and secured to the side walls, as at 17. An desired type of heating elements 18 may be employed. These elements are connected to an electric circuit by lead wires 19 and 20, one of which is connected to the lower ends of the heating elements and the other to the upper end. As shown, the lead wires extend" through a bushing 21, arranged in the base. The heating elements are connected to each'ot-her at the top and bottom by connecting strips 22.
The casing may be secured to the base in any suitable manner. In Figure r of the drawings, I have shown the casing having openings 24 adjacent its lower edge adapted to receive rivets or other suitable fastening elements passing through similar openings 25 in the projections 8.
The operation of the device will be apparent from the foregoing description. Air enters through the inlets 2 and 5 and flows upwardly through the casing. The natural draft caused by the tendency of the heated air to rise causes a ready circulation through the casing. The fact that the casing is wedge-shaped and larger at the top than at the bottom materially assists this flow of air as the expanded heated air is given a larger space through which to pass than the cold air entering the casing. The battles 23 are "i ill) arranged that they extend nearly to the center of the casing where the heating elements are located and in this way, the air is caused to flow over the heating elements a number of times during its passage through the casing, as indicated by the arrows in lfiigure 5 of the drawings.
An important feature of the invention is the provision oi a pair of inlets, one of which is adapted to be connected to an exterior fresh air supply. By regulating the damper 3, the proportion of fresh air to air withdrawn from the room for reheating purposes may be controlled. In this manner, the desired temperature within the room may be obtained and fresh air supplied at the same time.
It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
I claim:
1. In an electric heater, a base having an inlet opening, a casing mounted over said base and con'imunicating therewith, said casing increasing in width toward its upper end and being provided with an entirely open top, vertically disposed heating elements arranged in said casing, and battle plates secured to the walls of said casing.
In a device of the character described, a base having a plurality of inlet openings, a damper to regulate one of said openings whereby the proportion of air entering each of said opennigs may be controlled, a casing arranged over said base, said casing being provided with an open top, and baflie plates arranged in said casing.
3. In a device of the character described, a base having a pair of inlet openings, a damper to control one of said openings, a casing mounted over said base and communieating therewith, said casing increasing in width toward its upper end and being provided with an open top, Vertically disposed heating elements arranged in said casing, and upwardly inclined baflie plates secured to the walls of said casing and extending inwardly to a point adjacent said heating elements to direct air passing through said casing over said heating elements.
i. In a device of the character described, a hollow base provided with a pair of inlet openings, an inlet pipe communicating with one of said openings, a damper to control the other of said openings, a casing mounted above said base and coi'nmunicating therewith at its lower end, said casing being sub stantially wedge shaped to increase in width toward its upper end and being provided with an entirely open top, a plurality of vertically disposed spaced heating elements arranged in said casing, and upwardly inclined bafl'le plates secured to the inclined walls of said casing and extending inwardly to points adjacent said heating'elements, the
ba'lile plates upon opposite sides of said casing being staggered with relation to each other to direct air alternately from one side of said casing to the other through the spaces between said heating elements.
In a device of the character described, a hollow base having an inlet opening, a casing mounted over said base and communteating therewith at its lower end, said casing being provided with a plurality of balile plates secured against the inner face of one wall of said casing, the opposite wall of said casing being removable and provided with a plurality of ballle plates secured against its inner face and staggered with-relation to said first named bafile plates, and a plurality oi heating elements vertically arranged within said casing between the inner ends of said battle plates.
In testimony whereof, I aflix my si nature in presence of two witnesses.
