WALLRADIATOR f n Application filed May 31, 1930..,*Serial No. 458,122.

AThis invention relates toal radiator for walls and'other places, the general object of the invention being to form the coils of the radiator of oblong shape, with the side lportions straight and staggered and their ends urved so that the device can be manufactured j to sell at low cost and will occupy the minimum amount of space, with a by-pass having a vaive therein for controlling the flow of the heating or cooling medium, whereby such medium can be passed through the radiator or through the by-pass when it is desired to lcut od 'the radiator, or through both when it is desired to portion the temperature.` A further object of the invention is to so form the parts that the device can be placed in an opening in a wall or against a wall and the parts covered, with means for permitting air to enter the opening and pass therefrom 29 whereby the air will be heated or cooled and thus heat the room or other place in which the device is used, and may be temperatured as desired.

This invention also consists in certainother features of construction and in the combination and arrangement of theseveral parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a front view showing the device placed in an yopening in a wall, withvthe covering means removed and showing the check valve in section.

Figure 2 is a section on ure l.

Figure 3 is anend view of the device.

As shownV in these views, the radiator consists of tubing l wound to produce an oblong coil, of various shapes and sizes the side portions of which may be straight and the end portions may be curved, with ythe side portions at one side staggered in relationl to the side portions at the opposite side, so as to be of narrow width as clearly shown in Figure 2.

' rear lend `coil and in intermediate position, some of ythe device,

The side lportions are also diagonally ar'- ranged, as shown inFigurel.

A by-passpipe 2 is connected with the ends of thecoil and extends straight across the radiator, with a valve 3 arranged at the 'unction of the by-pass with the front end of thel coil and a valve or check valve 4 is arranged at the point of connection of the of the coil with the by-pass. This check valve or second valve acts to prevent water passing through the by-pa-ss from tlowing-back int-.ofthe coil and the valve 8 is so constructed rand arranged that in one position, it will permit the heating or cooling medium to pass through the coil without '69 passing through the by-pass. In another position, it will cause all the fluid to pass through the by-pass without. entering the thek hea-ting medium will pass through the o by-pass and some through the coil, in varied proportions according to the position of the valve. Thus this valve will control the flow of heating medium through the coil so that the temperature of the room or other place inwhich the device is located can be regulated.

Figures l and 2 show the device arranged in an opening 5 arranged in the wall A, with a part 6 of the coil passing through a hole S0 cut in a studding 7. Whenthe device is thus placed, a suitable covering can be placed over with grills 8 at the top and bottom of the opening for permitting a circulation of air through the openings so that 8 said air will be heated or cooled by the device and thus heat or cool the room. A small fan or ordinary construction can be placed in or behind the lower grill for increasing air circulation.

Thus it will be seen that I have produced a radiator which can be manufactured to sell at low 'cost and one which will occupy but little space, while producing the maximum amount of heat or cold. f

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the com- Hin bination and arrangement of the several parts, provided that such changes fall with in the scope of the appended claim.

What I claim is 5 A radiator of the class described comprising a` coil, a by-pass connected with the ends of the coil, a valve at the junction of the by-pass with the front end of the coil for permitting the Huid to pass through either the radiator or the by-pass or both and a check valve at the point of connection ofthe rear end of the coil with the by-pass, said valve first named being operable by dividing fiow, for varying relative pressures through the by-pass and coil respectively, on opposite sides of the second named valve.

In testimony whereof I affix my signature HORACE S. MELDAHL.
