f ELECTRIC LOG.
`Application filedA September 26, 1928. Serial No. 308,404.
My invention relates to an inprovement in electric logs.
The object of my invention is to provide a new type of electr-ic log which will provide an eliieient `heater and which willA not sacrifice to the bulk of the log an enormous proportion of the heat produced by the heater. H
Another object of my invention is to proio vide a heater which Will simulate the appearance of fire logs but which will provide for the` `disappearance of the logs when an actual heating operation is desired, mechanism for `acconiplishing the removal of the logs being provided for easy operation manually. i u f Another object of my invention is to provide an automatic switch which will turn olf the current supplied to heating elements in the heater ofA my log when the logs are in normal position. i
Another object of `my invention is to provide mechanical connections between the logs such as those described above in such a manner as to provide a spring' to assist in opening and closing the logs. Y u

Like parts are identified by the same reference characters throughout the several views. l'
My electric log is particularly desirablein fire places Where an auxiliary heating device is necessary at times and Where the inconvenience or impossibility of a wood or coal fire would otherwise make a fire place inconvenient or inoperative.
One of the principal inconveniences' and reasons for expensiveness of operation of the usual electric log lies in the fact that a large .55 portion of the hea-t produced electrically in the log is absorbed bythe body of the` log itself since the porcelain clay orl other dielectric material of `which most logs are made tend to absorb heat during` the iirst half hour or so of operation and do not provide effective heat radiation in proportion to the amount of electric current consumed.
In my log, therefore, I provide a combi.- nation of log structure in the form of metallic shell like bodies l0 and 11 each pivotally mounted upon a screw or other pivot point 12, which1 in turn is supported by a frame 13` provided with legs lst all of which have dimensions suitable for the establishment of my device in an ordinary fire p lace structure.
Sincev the log bodies lOand 11 are substantially hollow aspace is provided Within them for the installation of an electric heater vof the type usually referred to as a radiant y heater. `I prefer to form the back ground of this heater in the shape of a curved copper -or other suitable metallic rotlector l5 in front of which a suitable nu1n-. ber of `,dielectric supports 1G and a resistant coil 17 complete the actua-l heater structure.
Obviouslysuch a heater device if exposed Without. substantial projection is subjectl to injury and is not al very attractive article of furniture. For the purpose of protect-ing the radiant heater, tlierefore, I provide in the log bodies I0 and 1l a prete tion and an improved appearance as hereinafter indicated. e
As shown most distinctly in Figures 3 to 6, inclusive, the log bodies are formed in semicylindrical shape the ends of which are closed by circular metallic disks provided With apertures for Athe pivot screw 12. 'The log bodies are, therefore, pivotallyV mounted to rotate toward each other as indicated in logs Will automatically pivotally move the other log to asimilar position.
To assist in the operation lofrolling the logs to open or closed position, I have provided a spring 2l interconnected between the upper' log` at 22 and the traine at 23 and it will be understood from an examination particularly of Figure 3 that considering the weight et' the log bodies l() and 1l, the spring' member at full open position of the logs partially counterbalances the logs to prevent an excessive jar or shock when the logs roll to this open position and whenvthe logs are rolled to closed position the spring will assist in displacing the weight of the various parts during the operation.
Iuterconnected withthe logs so that any movement thereof will affect its position, I have provided a spring tensioned control cord 24 which is secured to the opening lever 25 ot a switch 26 and it will be noted that when the log bodies are rolled to closed position the cord 24 will be pulled downwardly with the result that the switch 26 will be opened and the current flowing through wires 27 will be unable to reach the wires 28 to complete a circuit to the resistor coil 17. A spring in the switch mechanism may be used to return the switch arm 25 to circuit closing position when the logs are opened, or, where preferred, the switch may remain open until manually closed when the logs are rolled to open position.
For purposes ot appearance only I have provided a special switch at 29 to complete a circuit with the wires 27 'tor the purpose of illuminating electric light bulbs 30 in the compartment 34 back ot the bodies l0 and 11 ot the logs with a result that when the electric connection is complet-e through the switch 29 and the logs are in either position an illuminationmay be provided, whereby a simulation of the appearance ot' glowing logs may be provided by the passage of light through the apertures ot the reflector at and 3l in the bodies ot' the logs, thus providing a single .article or device which will provide not only the appearance and simulation of a log tire but may upon occasion be called into service to provide all of the etliciency ot a radiant electric heater undiminished in its eiiiciency by unnecessary absorption of heat. in the structure itself or in the logs which simulate the appearance oit the log lire.
Iclaiin:
l. In an electric log, a trame, a radiant electric heater supported by the frame and an imitation log rotatively supported upon the frame, whereby to be positioned for concealment or exposure ot the radiant heater.
` 2. In an electric log, a trame and a radi- ,ace
ant heater including an electric circuit, a switch for controlling said electric circuit and an imitation log rotatively supported upon the trame, whereby to conceal or eX- pose the heater, and a connection between the rotative log and the switch whereby to close the electric circuit when the log` is i'otated to expose the heater. Y
3. In an electric heater, a reflector, an electric heating elementin front ot the reflector and an imitation log rotatively supported from said heater and said reflector, whereby to alternatively conceal or expose the reflector and the heating unit.
Il. In an electric heater, a frame having upwardly and downwardly' extending members,'a heater supported by the frame, an imitation log rotatively supported by the upwardly extended portion of the frame,
another imitation log rotatively supported by the downwardly extending port-ion of the trame, and a link'interconnecting said imitation logs, whereby to provide for simultaneous opposite rotation of the logs.
5. In'an electric heater, a set of logs each mounted for rotationeccentric oit the aXis of weight thereof, linkage between the logs to provide for simultaneous opposite rotation thereot and a spring` for counter-balancing the rotation ot said logs. y
G. In an electric log, a trame having extended arms, logs comprising metallic shells rotatively mounted upon said arms, a radiant heater supported vby said frame within the shells ot said logs and a link between said logs, whereby to simultaneously oppositely rotate said shells to expose the heater.
7. In ancelectric log, a 'frame having extended arms, logs comprising metallic shells rotatively mounted upon said arms, a radiant heater supported by said frame within the shells of said logs and a link between said logs, whereby to simultaneously oppositely rotate said shells to expose the heater,
and a spring between one of said shells and the frame whereby to resiliently restrain movement of said shells to completely open and completely closed position.
8. An electric heater including a heating unit and an electrical circuit for control thereoil together with a switch, a shellinovable to and trom a position ot concealment HARRY HERSH.
