T0 azzv whom' a may @www Be it known that I HARRY E. STRUNK, a citizen of the United States,

of San Bernar ino and have invented a new tario, in the county State of California,

A CORPORATION OF CALI- HEATER. Application led August 1 8, 1917. Serial No. 185,898.

at Onand useful Heater, Iof which the following is a specification.

My invention relates to portableelectric heaters in which the heat from the heating element is directed direction. l of commerclal value,

and concentrated in some As such heaters, in order to be' must be comparatively light, there is considerable danger of suc heaters being upset, position as to direct covering, thereis great dan heater which is 'so shaped, weightI is so distributed,

and if upset to such a the heat'of the element against an inflammable floor material or floor ger of scorching or burnlng the floor material or coverm .l

An object of my invention is to provi e a that the and in which the heater when upset will automatically turn into a safe position.

In the drawings, which are for illustrative purposes only:

Fig. 1 is a front elevation of the heater, a portion of the guard being broken away, and

a portion ofthe heating section.

Fig. 2 is a side elevation,

unit being shown in partly in section,

showing the method of adjusting the heater. Fig. 3 is a view, on an enlarged. scale,

showlng the method of to the reflector.

bottom, as it would appear were it held the hand, as shown in that osition is in an inmediately roll Fig. 6 upon reof the heater lying on its osition which it will as-v The heater shown in these drawings consists of a reflector ard 12 and provided wit 13 and a guard 14. The erably of parabolic shape with a handle 20 by which be transported from place 11 supported on astanda heating element reflector 11 is prefand is provided the heatervmay t0 place.

Itis

.thattheheat raysl from the be directed downwardly in the drawings,

also rovided with a socket 21 into which a stan ard attachment plu 22 may be inserted, this attachment Eig 22 being rovidedwith a duplex flexible cord 23 th-rough which electricity is supplied to the heater. Located inside the socket 21 are terminals 24 which pass through the reflector 11, being insulated therefrom.

Secured to the refiector 11 is a standards 25, preferably formed o metal, which are bent as shown in Fig. 4 and which are provided with Vsmall ears 26, shown in that ligure. The standards 25 are preferabl formed of sheet metal and have considerable spring so that they are held pressed inside an insulating cylinder 27 of the heating element 13, fine wire 28, preferably in coils, being wound around the outside of the cylinder 27 and having terminal wires 29 which pass back and connect to the terminals 24. The cylinder 27 can be read ily removed from the standards 25 by springin them out at A in ig. 4. y

lIn operation, the wire 28 is raised to a glowing-temperature, and it is necessary to protect it from accidental contact with fabrics. This is accomplished by means of the guard 14 which consists of a series of wires 30 which are connected to a common central point 31, and which are connected at their other end to a ring 32.` This ring is provided with small hooks 33, as best shown in Fig. 3, which pass throu h' holes 34 formed in the reflector 11 at t e top and bottom thereof. The guard 14 is readily removed by press' downwardly jacent toute upper hole 34, thus springing the hook 33 downward and allowing it to be withdrawn through the hole 34.

The reflector 11 is provided with a pair of ears 35 which are pivoted on a screw 36 which passes through a cap 37 of the standard.12. This standard 12 has a base 38 which may be' of an desired ornamental form. Were the gua 14 to be made Hat in form, or were it to bel dispensed with, the reflector if overturned might fall in such a position reflector 11 would air of For the purpose of preventing this I prefer to give the r guard 14 a curved shape, asshown and in addition I place in the base 38 a heavy weight 39, the 'center of sheet l against the carpet. v

on the ring 32 adan angle M o approximate central plane N-N of the reflector 11. By

placing the center of gravity off as best shown in Fig. 5, the heater when placed in the position shown in Fig.` y5 .wiil tend to rotate in 41, assuming the position shown inv Flg. 6, It will also tend to assume the position shown in Fig. 6 if placed in any vposition other than one which would make it tend to assume position shown in Figs. land 2li v The method of operation of the invention is as follows: f '52 'n The heatingeiement being su plied'with current through the Wires 23, is irought up to a glowing heat, and this heat is directed outwardly from parallel rays by tion of these rays of heat can yhey readiiy cha ed into a horizontal plane hyadjusting t e positionof the whole heateraround its vertical axis. For the purpose oi" changin the direction of the heat up or down, the adjustment about the screw 36 is provided, 'the heater 'being readily adjustable from the position shown in iull lines in Fig. 2 to the osition shown in dotted ii-nes in that figure. y this means the heat can he directed to approximateiy any position desired:

l have found that by the use of a heater of this kind it is ossible for a personto he quite comfortab e even in a very cold' room, so that it is unnecessary to provide, in elec tric heating, "for heating the entire space about the person. In other words, proly from the center,

the direction of the arrow` the heater in approximately the reiector 11. The direc"` weight so located as to vide for heating the body of the person desi'l'ingl the warmth and not the surrounding an'.

, Iclaim my invention -1.j In an electric heater, a reflector; and an outwardly curved guard over the front of said'reilector, the weight-of said heater hein so'fdistributed that said heater tends to rol into aposition with the guard upward when overturned. f

2; In anelectric heater a heating element; a reflector for said heating element; a stand; and the mass of said heater uted that said heater is in unstable equilibvriuin in any position which wouidrelect the heat dovvnvvfard.`

. 3.- nan electric heater, a heating element; i

areector for said heating element; a stand supporting said element and reector; and a said element and any 'iiat surface heater may be overturned. as in claim 3 in which base of said between upon which said 4. A combination said weight is placed in the stand.. v

5. In a portable electric heater, a heating element and a standard andl reiiector fory directing the heat fromv saidv element, `the weight of said parts being so distributed that if saidheater is left in such a position as to direct the heat downward, it will automaticaily move from such position.

In testimony whereof, I have hereunto set my hand at Untario, California, this 3rd day of August, 1917. Y HARRY E. STRUNK.
