W gl-uvtgzoaq Anon Ys suchas to render a small supply'of heat ex- UNITED, STATES PATENT OFFICE.
EDMOND c. rLomo'r AND GEORGE 1. copy, on NEW YORK, N. Y.
and GEORGE F. Cour, citizens of the United States, residing in the city of New York,
county of New York, and State of New York, have invented a certain new and useful Improvement in Electrical Heaters, of which the following is a specification.
()ur invention relates to that class oide vices which are designed to furnish heat temporarily to warm up cold room Where there is insufiicient radiation or in that time of year when the weather is not severe enoughto require a fire in the heating plant on the premises and is particularly desirable in the South, where houses are not equipped with heating plants and there are frequently days when the temperature is tremely desirable.
Devices of this kind with which we are familiar, are made to set on floors or tables andare more or lessbulky. Our device is designed to be portable and is arranged to be suspended from any electric lightfixture or fromthe chandelier in the center of the room. Where one ofthe floor devices is to be suspended in this mannerthe heat would, in a very short time, melt the connections and the device would fall to-the floor.
Our invention has for its object to provide means for overcoming this objection and to provide a construction in which the operative mechanism will be entirely protected by a casing but which will be ,so arranged that it can be quickly and easily got ten at in the event of repairs or for the purpose of assembling.
Our means of accomplishing the foregoing objects maybe'more readily understood by having reference to thefaccompanying drawings which are hereunto annexed and are a part of this specification in which Figure 1 is a side view of our improved device a part'of the'casing being broken away to show the interior construction.
- Fig.2 is a cross section taken on the line in Fig. 1. i Fig. 3 is an enlarged fragmentary detail view of the securing means at the top of the casing. c i i Fig. 4 is an enlarged fragmentary detail Specification of Letters Patent.

view of one of the supporting elements for the heat insulating device.
Flg. 5 a fragmentary detail view of the construction at the bottom of the casing.
Similar reference numerals refer to simi lar parts throughout the entire description. I is shown in the drawings our device comprises a cylindrical casing 1., the walls of which are foraminated to permit the escape of the heat units to the atmosphere. As shown in the drawings most of the foraminations are omitted for the sake of clearness, they being shown on the casing which is shown in elevation and indicated in the sections.
The casing 1 is provided with circumferential flanges 2 and 3. These fiangesare adapted to engage closures 1 and 5 mounted at the bottom and top respectively of the foraminating casing l. The closure 41 is provided with a circumferential flange 6 at its periphery which is adapted to be turned over and clamped upon the flange 3 on the end of the cylindrical casing 1, thus effectually preventing its removal except by the use of tools. The lower part of the closure 4 may be provided with an ornamental tassel T of any desired configuration.
1 The resistance 8 is carried by a plurality of supporting members 9; as shown they are three in number. These supporting elements are formed as is more clearly shown in Fig. 4, with a plurality of notched portions 10 intermediate which are outwardly extending lugs 11. These lugs are inturned as clearly shown inthe sectional view Fig. 2 and form brackets upon which are mounted a plurality of disks 12 formed of suitable heat resisting material; in our construction we have found mica to be very desirable for this purpose. Binding posts 13 and 14: are suitably mounted by means of nuts 15 and 16 in the upper heat resisting disk 12 and are connected to electrical conductors 17 which pass through anopening 18 in the top of the closure v5 and are suitably secured to an electric plug 19 of the usual standard construction for fitting the standard electric light socket, the two wires being carried to the plug by a cable 20; electrical conductors 21 and 22 extend downwardly from the binding posts carried by the top disk 12 to binding posts 23 and 2% which are mounted in a disk 25 which carries the resistance coil 8, this coil being secured to the disk 25 by means of a bolt 26 and nut 27 and washer 28 mounted on the said bolt, thus operating to hold the coil rigidly in position.
The ends of the coil 8 are attached to the binding posts 23 and 2 1 in the usual or customary manner. The disk 25 is also made of suitable heat resisting material. The upper closure or cap 5 is provided with a downwardly depending flange 29 which is provided with a plurality of openings 30 in which is mounted a plurality of screws 31 which are operated to hold the can or closure 5 securely to the for'aminated casing 1. The upper ends of the supportin members 9 are bent outwardly forming hook 32 which are adapted to rest upon the circumferential flange 2 of the foraminated casing 1 and thus support the heat resisting disks 12 and 25 and the binding posts 13 and 14, and 23 and 2t and the electrical conductors 21 and 22 together with the resistance coil 8.
These hooks 29 are firmly clamped intermediate the wall of the closure 5 and the circumferential flange 2 of the foraminated casing.
The device is assembled in the following manner.
The casing 1 is first constructed with the circumferential flanges 2 and 3. The closure 4k is fitted over the circumferential flange 6 and the closure is then inturned and pressed down securely upon the circumferential flange 3 on the foraminated cylinder 1, thus completely closing the lower end of the casing 1. The supporting elements having been first notched as at 1.0 and the intermediate lugs 11 inturned, the disk 25 is secured to the lower end of the supporting elements. The binding posts 23 and 2st are placed in position; the bolt 26 is dropped through the disk 25, the resistance coil 8 mounted upon the bolt and the washer 28 is then placed in position and the nut 27 secured on to the bolt 26 securely and rigidly fastening the resistance coil 8 to the disk 25. The ends of the resistance are then suitably connected to the binding posts 23 and 2 1-. The heat resisting disks 12 are then mounted upon the inturned lugs 11 and the electrical conductors 21 and 22 are passed through suitable openings formed in the heat resisting disks 12 connected to the binding posts 23 and 24:. These conductors are provided with suitable bushings 34 of proper insulating material. The upper ends of the conductors are then connected to the binding posts 13 and 14; while the ends of the electrical conductors 17 are attached to the binding posts 13 and 14 respectively, the opposite end of these wires 17 having been previously attached to the plug 19. It is now apparent that the device is all ready to be inserted inside of the casing 1. It is then lowered into position, the outwardly extending portions or hooks of the supporting members 9 engaging the circumferential flange 2 at the top of the casing. The downwardly depending flange 29 passes down over both the hooks and the circumferential flange 2; the screws 31 are inserted and screwed into position when the whole device forms a unitary structure and is ready for use.
It will be apparent from the foregoing description that by this construction we have entirely obviated any possibility of the deleterious action of the heat generated by the resistance coil 8 and that the device is thoroughly practical. Practice has shown that it can be heated for an indefinite number of hours without injuriously affecting the insulation of the wires 17.
While we have described a specific type of container, it will be understood that we do not desire to be limited to the precise construction shown, as many changes may be made in the construction which is only to be limited by the hereinafter appended claims.
Having described our invention what we regard as new and desire to secure by Letters Patent of the United States is:

In a device of the cha acter described the combination of a cylindrical casing the walls of which are foraminated, of an electric resistance mounted in said casing, a plurality of supporting members carried by said casing from which said electrical re sistance depends, there being a plurality of notches formed in the edges of said supportin members, a plurality of lugs intermediate the said notches said lugs being inturned, a plurality of mica disks carried by said lugs, binding posts mounted in the upper one of said disks, electrical conductors connecting said binding posts with said resistance coil and means to connect said binding posts to a suitable supply of electric current, means to permanently close the lower end of said casing and means to detachably close the upper end of said casin 2.
