.BUSSEL SUTHEBLAND SMABT,,-OF OTTAWA, ONTARIO, CANADA, ASSIGNOR TO JOHNS- TON, DRYDEN &'CO., INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF Application filed may 14,
This invention relates to improvements in electric heaters of the type in which the heating element or coil is located within a refiecto r, and the objects of the invention are 6 to generally simplify and improve the construction and enable the heating element to be readily attached and detached and to enable the device to be constructed in part of well known standard articlesin the electrical manufacturing field and. it consists, essentially, of the improved construction hereinafterdescribed in detail in theaccompanying specification and drawing.
In the drawing Fi ure 1 is a perspective 15 view of the device. igure 2 is a cross sectional View. Figure 3 is a detail showing the electric heating element. Figure 4 is a sectional detail of the socket which extends thru the reflector. Figure 5 is a sectional de- 20 tail of the plug, attached to fit the screw.
. In the drawing, like characters and numbers indicate corresponding parts in the figures. Referring to drawing A represents the reflector of any convenient type, preterably of metal, such as sheet copper, and concave in form after the manner of search light reflectors. The reflector is supported from a suitable standard B the arms of which may be pivotally connected by pivot screws 12 to lugs 11 on the side of the reflector, C represents the socket member of any well known type such as used to support and supply electrical current to an incandescent lamp. A detail of a well known form of socket is'shown in Figure 4. The
inside of the socket is provided with a threaded cylindrical connector sleeve 14 connected to a binding post'15 to which one of the current connecting wires 16 is attached.
The other current connecting wire is attached 'to the post 17 which connects to the contact 18, adapted to engage the inner end of the contact of an incandescent lamp bulb, or a connecting plug inserted in the socket.
c D represents a connecting plug adapted to fit the socket and to form the socket or connector for the heating element E. The plug D may be of any well known type. As illustrated it is formed with slots or sockets 19 and 20 into which contact finers are adapted to extend. The plug D as" 8 metal screw threaded sleeve; 21
convenient manner.

1917, Serial No. 168,570.
A second spring contact 23 is provided in the slot 20 and connected with a terminal contact button or point 24. The heating element E comprises a cylindricalcore 30 of heat insulating material such as porcelain on which is spirally wound a coil 31 of resistance wire such as nickel-chrome wire suitably designed with respect to the -current to be supplied so as to be brought to incandescence when the current is passing through it. The ends of the heating coil are electrically connected to supporting members 32 and 33 which as shown are formed with rings 35 and 36, which embrace core 30 but which may be connected thereto in any other The inner ends of the connectors are spaced apart to form parallel contact fingers 37 and 38 adapted to enter the slots or sockets 19 and 20, to complete the electrical connection, and having sliding engagement with the spring contacts 22 and 23. The connectors 32 and 34 may be connected together and braced by a bar of insulating material, 39, suitably connected to the connectors.
It will be seen that the heating coil may be readily withdrawn, arising from the fact that the contacts 37 and 38 have sliding en gagement with the spring contacts 22 and 23. If desired the plug D may be unscrewed as well, in which event an incandescent lamp bulb might be placed in engagement with the socket G instead of using plug D. This enables the device to be used either as an electric heater or lamp.
It will be noted that in carrying the invention into practice various changes within the scope of the following claims may be made without departing from the spirit of the invention.
What I claim is:
1. In an electric heater, a heating coil, a two part socket having onepart adapted to enter a screw socket for an incandescent lamp, and having the other part formed with an electric terminal, connecting means adapted to supportthe heating coil in advanceof and extendin transversely across the socket having sliding contact with. the
terminals thereof and being detachable from the socket by a pull exerted in a direction transverse ol the coil.
2. In an electric heater, a heating coil, a terminal socket formed with two spaced terminals, connecting means adapted to support the heating coil in advance of and extending' transversely across the socket and being formed with spaced contact lingers adapted to ha YQ sliding contact with the terminals on the socket. and an insulating 1nemoer connecting the spaced contact lingers.
3. An element of an electric heater coni-
