This invention relates to improvements in cross flow radiators, and has for its object .to provide a radiator and Ventilating apparatvus in which the air is uniformly heated and discharged into a room in' a uniform temperature condition.

It is also an object of this invention toA provide, in connection with a VentilatingA and heating apparatus, means for creating a current of lair and directing the air from outside of the building to a point on the inside,

and then this air is discharged into the build-- `ing to allow it to be retarded in its forward movement and expand, and` after it has exp having the tins arranged in a longitudinal position with relation to the casing in which the fan element is located and suiiiciently lremoved from the fan element. the air can expand and that the amount of material in 4the radiator may be materially reduced.

Under ordinary conditions a radiator six inches high would be necessary if the tins run crosswise of the casing, but with the longitudinal arrangement and the expansion space radiator fins no higher than two and a half inches may be used, vand produce the sanie result as radiators six inches high would produce if the fins were crosswise of the casing instead of longitudinal.

B y reducing the height of the radiator the total. height of the casing mayfbe reduced, thereby. enabling the whole unit to be used under lower windows than with higher heaters and larger casings.

YThese and other advantages will'appear from the following description, taken in connection with the drawings, in which there is shown a vention. A

' Referring to the drawings:

Figure 1 is a vertical section on the line 1-1 of Figure 3.

Figure 2 is a view showing a part of the front of the casing. A

Figure 3 is a vertical section on the 3--3 of Figure 1. `Figure 4 is a top plan viewr of a radiator. Figure' 5 is a section on the line 5-5 of Fipure 4.

.Figuret is a section on the line 6 6 of preferred embodiment of this inline Figure 5. panded, pass over heating tins by which ,the air is uniformly heated and tempered for t Figure 7 is-an end elevation of the radiaor. This air conditioning and air heating apparatus is inclosed within a casing 1. which has an inlet opening 2 for the admission of fresh air into the interior of the casing. The admission of fresh air into the casing is regulated b v means of a damper 3, as shown in Figure 3. This damper may be arranged i to have automatic control or it may be manuallv controlled. The damper control is no part of this invention.

The lower part of the casing is designated a chamber 4 into which cool. fresh air is admitted from the outside throughthe inlet 2. rihis chamber has side walls'` as'shown in Figure 1` and has an outlet 6 through which the air passes from the chamber into a fan chamber 7. The fan chamber in the present instance hasl two fans. Different numbers of fans mav he used. depending upon the size of the casing and the size of the fans.

Fan casings 8 are shown to be convolute in form with lateral openings therein for the admission of air into the casing. These lateral openings or inlets are indicated h v the numeral '9. ln the casing isa fan 10 operated by a motor 11, which has a shaft 12 for operating the fans and to which the fans are attached. While the inlets to the fans are laterally disposed-the outlets 13 lead upwardly into an expansion chamber, to be later described. The inlet part of the fan is funnel-shaped so as to direct the air from the fan chamber into the. fan casings so that it may be delivered for heating purposes to the expansion chamber.

'In each side of the main casing and attached to the walls thereof are brackets 14, which have downwardly inclined parts 15 which tendto direct the incoming air into the fan .casings The part of each bracket immediately above the inclined part is formed into a shoulder 16 for supporting a plate 17 immediately above the exit or outlet from the fan casings. This plate has as many openings therein as there are fans in the fan chamber, and adjacent each opening and to each side thereof there is formed a turned-down flange 19 which projects into the outlet part of each fan casing and serves, in cooperation with the fan casings, to direct the air through openings 18 in the. plate.

vLocated in the openings 18 and immediately above the outlet from the fan casings are diagonally disposed deflectors 20. In the present instance four of these deleetors are shown in connection with each fan, and

of these four delectors two slant upwardly in one direction and the other two slant upwardly in another direction. By this means the air as'. it leaves the fans is divided into' all parts of the chamber.

This expansion chamber permits the air to expand and lose a part of its velocity so that as it reaches the radiator its motion is not so rapid and it has substantially a very broad cross sectional area of movement at -substantially a uniform speed for'all crosssections of the area. The upper parts of the brackets 14 are formed into ledges 21 which -supportlegs 22, extending downwardly from a heater or radiator 23 which has at each end a right angular projection 23a. The legs 22, with the brackets 14, form the expanv sion chamber 24, into which the air passes after leaving the fans and in which it expands before entering the heater or radiator.

It will be noticed from the arrangement of the deflect-ors that the air is directed in currents longitudinally of the casing, and in order' that the radiator fins may have the greatest effect upon the air they are likewise arranged longitudinally of the casing so that there is an equal distribution 'of air through the length of the radiator.

The heater has an inlet 25 and an outlet 26' connected to the projections for the admission and discharge of hot water or steam for heating purposes. Thenature of the radiator or heater is shown well in Figure 4. The radiator is composed of two casings or headers connected by pipes or tubes 27.

I nto one of these casings the hot water or steam is admitted through the inlet, and from this casing it passes into the other casing through the pipes ,27, and .romtheother casing out through the dischargev `orl outlet 26. The two casmgs are also connected by a pipe 27a between one end of one casing i casing is a cover,29 which has an outlet opening 30 therein through which the airpasses from the main casing after passing through the heater and about the heating fins. This outlet may have provided therein louvers or means for controlling the current of air from the main casing into the room or building heated by the apparatus.

I desire to comprehend within my invention such modifications as may be embraced within my claims and the scope of my invention. Y
