ELECTRIC HEATER.

Patented Feb. 15, 1921.

Application flied April 18, 1919. Serial No. 290,467.

To all whom it may concern:

Be it known that we, FRANK KUHN and JAY A. HAND, both citizens of the United States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Electric Heaters, of which the following is a specification, reference being had therein to the accompanyln drawings.

This invention relates to electrlc heaters, and particularly relates to luminous electric heaters.

It is the object of the invention to provide an electric heater comprising a standard and luminous heating units carried thereby, which standard is angularly adjustable with relation to its base so as to permit the direction of the radiatlon of heat to be varied by an adjustment of the stand ard, permitting also the base to rest either upon a floor or other horizontal support, with the standard projecting upwardly therefrom, or to be secured to a wall with the standard adjusted either parallel or at an inclination to said wall.

Further features of the invention lie in the provision for establishing a detachable electrical connection with the standard from any suitable source of current, and for switching the heating units into use in pairs.

In the accompanying drawlngs:

v Figure l is a view of the heater in front elevation;

Fig. 2 is a side elevational v1ew of the same, .partly in section, showing in dash lines a different position of adjustment of the base;

Fig. 3 is a vertical section on line 3-3 of Fig. 1;

Fig. 4 is a diagram of the electrical 'connections.

In these views, the reference character A designates a standard mounted u on a base B and supporting a plurality o luminous electric heating units C, of which there are preferably four, constituting a lower and an upper pair, the members of WhlCh are respectively at each side of the standard. The heating units, which are in themselves not novel, may each comprise the coiled resistor I), a mounting E for said resistor, the reflector F and the wire guard member G.

The standard A is pivoted to swing forward and back upon the base B, the latter being preferably provided with a short bifurcated post H, between the furcations of which the lower end of the standard A is engaged, a bolt I being employed to establish the ivotal axis and to maintain a sufiicient rictional stress to hold the standard in any desired position of angular adjustment with relation to the base. In the rear wall of the lower portion of the standardA there is inserted a socket member J, provided with a pair of contact pins K engageable by a form of plug, well known in the art. Through the front wall of the standard there project two push buttons L, controlling switches M located within the standard for respectively controlling the upper and lower pairs of heating units. Thus the heating effect is regulable and may be derived from either the upper or the lower pairs of units or from both pairs.

When the base B rests upon a floor or other horizontal support, the standard A may be inclined either rearwardly or forwardly in case it is desired to direct the heat either at an upward or downward angle. In some'instances, it may be desirable to mount the heater upon a wall in which case the base B may be secured to the wall, as indicated in dash-lines in Fig. 2, and the standard A may be adjusted vertically adjacent the wall so as to radiate the heat away from the wall.

To facilitate assembly the rear wall N of the standard is made detachable, said wall being normally held in place by screws 0. By mounting the socket member J upon this detachable wall, it becomes possible to establish the electrical connections from said socket to the switches and heating units without the workmen being hampered for lack of room. After establishment of the connections, the conductors may be thrust into the standard as the wall N is being shifted into place. 7

The standard A is surmounted by a detachable cap P, the front and rear walls of said cap and standard being formed with registering slots B through which are passed the bent lower ends S of a handle member T, whereby the cap is held in lace upon the standard. The resiliency o the handle member serves to permit eat and disengagement of its extremities S from said slots.

What we claim as our invention is:

1. An electric heater, comprising a plurality of electric heating units, a standard supporting the same, and switches carried by said standard for closing the circuit of said units in pairs.

2. An electric heater, comprising a base, a hollow standard rising from said base including a detachable member extending substantially the height of the standard, a heating device carried by the upper portion of the standard, asocket member carried by the lower portion of said detachable member, and conductors within said standard leading from said socket to said heating device.

3. An electric heater comprising a base, a hollow standard rising from said base, a portion of said standard being detachable to give access to the interior thereof, terminals carried by said detachable portions, normally located within said standard, a heating device carried by the upper portion of the standard, and conductors extending within the standard from said terminals to said heating device.

4. An electric heater, comprising a base, a hollow standard rising from said base, a heating device supported by the upper portion of said standard, conductors for said heating device housed Within said standard, a cap surmounting the standard, and a handle member engaging the cap and standard and maintaining the same in proper relation.

5. An electric heater, comprising a base, a

hollow standard risin from said base, a heating device mounted upon said standard, conductors leading to saldheatin device and extending within the standar a cap surmounting the standard, the cap and standard being formed with registering openings, and a handle member having a portion engaging said openings to maintain sald cap and standard in proper relation.

6. An.electric heater comprising a base, a hollow standard rising therefrom, a heatmg device carried by said standard, c0nductors leading to said heating device housed within thestandard, a cap surmounting the standard, said cap and standard having registering openings at opposed sides thereof, and a resilient handle member having bent extremities yieldably engaging said openings and retaining the cap and standard in assembled relation.

7. An electric heater comprising a luminous heating unit,va tubular standard carrying said unit, a base upon which said standard is angularly adjustable and switch mechanism positioned interiorly of said standard and controlled exteriorly thereof.

8. An electric heater comprising a base and standard rising from said base and a plurality of luminous heating units arranged in pairs upon said standard, the units of each pair being at opposite sides of the standard.

In testimony whereof we aiiix our signatures.
