BASEBOARD PANEL HEATER Filed Oct. 22, 1956 2 Sheets-Sheet 1 INVENTOR BASEBOARD PANEL HEATER Max Nathanson, Montreal, Quebec, Canada Application October 22, 1956, Serial No. 617,470

8 Claims. (Cl. 21934) This invention relates to baseboard panel heaters for recessed or surface mounting on a wall and relates more particularly to glass panel heaters in which a basic heating unit is adaptable to any form of baseboard panel having a common type of unit mounting and wire terminal boX.

The invention consists essentially in the provision of either a recessed or surface mounting wall panel both having the same form of heating panel mounting and wire shielding box and a basic panel heater completely wired, the basic panel heater being provided with end compartments, enclosed by removable front covers, within which the necessary wiring connections can be'made between the heating element and the house wiring after the assembled heater has been mounted in place on the wall,

The object of the invention is to provide a baseboard panel heater which can be used as a surface mounted heater Where no provision has been made in the Wall to recess such heaters, or can be fitted into ready prepared recesses in the wall by the simple provision of exchanging one type of wall panel for another.

A further object of the invention is to provide a baseboard panel heater in which a basic heating unit is completely wired and has wiring leads brought into a separate end Wiring compartment where the leads can be connected to the house wiring without disturbing the heating element itself or its housing and guards.

A further object of the invention is to provide a baseboard panel heater in which the heating element can be removed from its housing and be replaced without disturbing the baseboard panel as a whole.

These and other objects will be apparent from thefollowing detailed specification and the drawings forming a part thereof, in which- Fig. 1 is a vertical elevational front view of a baseboard heating panel adapted for surface mounting on a wall.

Fig. 2 is a vertical cross section on the line 2-2 of Fig. 1.

Fig. 3 is a vertical cross section similar to Fig. 2 but showing the panel recessed into a wall.

Fig. 4 is a vertical front view of the basic heating unit removed from its wall panel and without its wire guard.

Fig. 5 is a cross sectional view on the line 5-5 of Fig. 4.

Fig. 6 is a fragmentary front face view of a surface mounted wall panel showing the mounting and supporting brackets for the basic heating unit, and the wire shielding box.

Fig. 7 is a vertical section on the line 7-7 of Fig. 6.

Fig. 9 is a fragmentary face view of one end of the basic heating unit with the front cover and corner brackets removed to expose the space for the Wiring connections.

ts atent 2,849,586 Patented Aug. 26, 1958 Referring to the drawings, the baseboard panel heater 5 is composed of two main portions, the Wall panel 6 and the basic heating unit 7.

The basic heating unit 7 is in the form of a shallow rectangular tray of suitable dimensions considering the locations in which the heaters are to be fitted and the voltage of the supply. The tray is formed of sheet metal and has a base sheet 8 extending the full length of the unit and is turned up at the ends to form the endwall-s 9 and at the sides to form the side walls 10. The side walls 16 are inturned along their top edges to form theflanges 11. Z-shaped members 12 extend across the tray to form end compartments 13 within which the wiring connections between the supply and the heater are'jo-ined. The glass panel heating element 14 is mounted in suita'ble spacers 14a within the centre compartment 15 of the tray and is held in place by the corner brackets 16. End cover plates 17 are secured to the flanges 18 of the tray by means of the screws 19. A bushing 20 is fitted in the base sheet 8 in one of the end compartments 13 through which the supply wires 21 are brought into the compartment 13, while a bushing 22 is fitted through the adjacent Z-shaped member 12 to carry the terminal wires 23 from the glass panel heating element 14 into the com' partment 13, where they can be suitably joined with the supply 'wires 21.

A wire guard 24 generally covers the area of the glass panel heating element 14 and the centre compartment 15 and is secured to the flanges 11 by the screws 25. The wire guard 24 serves to hold down the corner brackets 16 but is clear of the end cover plates 17 to enable these cover plates 17 to be removed to expose the connections of the wires 21 and 23 without disturbing any other part of the heater assembly.

The wall panel 6 shown in Figs. 1, 2, 6 and-7 is suitable for surface mounting on a wall and is here shown as being in the form of a picture frame although it could be in any other form to give a degree of protection around the edges of the basic heating unit 7. The base sheet 26 of the panel 6 isformed with outwardly sloping side wall 27 inturned at 28, to give a smooth finish around the edges of the panel. Brackets 29'a1'e secured to the base sheet 26 at the corners where the base sheet joins with the sloping walls 27 and have secured to them The threaded screws 31 passbasic heating unit 7 as required. The

brackets

29 and 33 space the basic heating unit 7 away from the wall panel 6 to provide an air circulating space 6:: therebetween to provide a more eflicient air circulation than is normally available in baseboard panel heaters. A wire shielding box 34 is provided in the base of the panel 6 into which the supply wires 21 from the wall box 21a are led through the aperture 35 from a wall outlet. This wire shielding box 34 is located in line with the bushing 20 in the end compartment 13 of the basic heating unit 7. The Wire shielding box 34 is approximately the same height above. the base sheet 26 as is the top surface of the

brackets

29 and 33 and serves to isolate the wires 21 in the open space between the heating unit 7 and the base sheet '26.

In Fig. 8 the same arrangement of

support brackets

29 and 33 and wire shielding box 34 is shown as in Fig. 5

but the panel 36 is for mounting on a recessed wall as shown in Fig. 3. The panel 36 is dishedwith straight side walls 37 projecting out from the base sheet 38 to support the wall flanges 39.

When it is desired to mount a panel as above described on a wall, the front cover plate 17 covering the end compartment 13 immediately over the wire shielding box 34,

intermediate support brackets 33 are provided at suitable intervals to give added support to the Suitable insulating spacers 4t) are fitted on the base sheet 8 to insulate that sheet from the heater element 14 as a short circuit protection should the base sheet 8 be dented or become warped in usage. A current limiting thermostat 41 may be fitted as required.
