UNITED STATES WALTER CLARK, or TORONTO, ONTARIO, CANADA.
ELECTRIC HEATER.
Application filed December 31, 1923. Serial No. 683,733.
To all whom, it may concern:
Be it known that I, WALTER CLARK, a citizen of Dominion of Canada, and resident of Toronto, in the county of York and ,Province of Ontario, Dominion ofCanada, have invented certain new and useful Imfied and improved construction with novel 1, looking in the direction indicated by the ion requires.
heating elements suspended on the heating element supporting and heat reflecting plate of the heater.
The invention has for another ob ect the provision of an electric heater of the character stated in. which is employed an arcuate plate for supporting the heating elements and reflecting the heat rays both downwardly andupwardly as well as forwardly.
The invention has for another ob ect the provision of an electric heater of the character stated whichis composed of the minimum number of parts of simple construction and arrangement and whlch may be readily assembledpr taken apart, as occas- -With the foregoing and other objects in View as will appear as the description pro "ceeds, the invention consists in the novel I construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings formmg a part of the present a plication, 1n which Fig. 1 is a rent elevation of the improved heater.
arrows.
Fig. 3 is a slightly enlarged fra mentary detail section, substantially on t e plane or line 33 of Fig. 2, looking in the direc-' tion indicated b the arrows.
Fig. 4 is a ragmentary detail section, substantially on the plane of line 14 of Fig. 1, looking in the direction indicated by the arrows.
Fig. 5 is an enlarged fragmentary detail section, substantially on the plane of line 5 .-'-5 ofFig. 3, looking in the direction indicated'by the arrows.
Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, it will be noted that the heater includes substantially C-shape end plates 10 with depending corner legs 11, as shown clearly in Fig. 2. The end plates 10 may gray iron castings, if preferred and are placed in parallel spaced relation with the steel body plate 12 mounted therebetween. The steel body plate 12 is also of substantially C-shape in cross section or end elevation and the longitudinal edges thereof are engaged in slots 13 provided therefor in the inner faces of the end plate 10. The upper and lower edges of the body plate-12 are curved upon themselves to form the rounded upper and lower forward edges 14 for the body plate 12, as shown clearly in Figs. 1 and 2. The front plate 15 is spaced forwardly of the main portion of the body plate 12 with its longitudinal edges engaged in slots 16 provided therefor in the inner faces of the end plates 10 and substantially parallel with the main portion of the slots 13 for the longitudinal edges of the body plate 12. This will be clear from Figs. 2 and 4 of the drawings. It will also be noted from these views that the main or central portions of the body plate 12 and the front plate 15 are substantially vertical, while the upper and lower portions are 'curved with the upper and lower longitudinal edges 17 of the front plate 15 engaged against the turned back upper and lower longitudinal edges of the body plate 12. The front plate 15 is preferably a polished copper plate and serves as a heating element supporting plate and a heat reflecting and spreading plate. Connecting and braclng rods 18 are extended through the upper 1 and lower portions of the end plates 10 to connect the same and retain the body plate 12 and front plate 15 in proper position between the end plates 10. This is clearly shown in Figs. 1 and 2.
Projecting forwardly through the central or vertical portion of the front plate 15 are upper and lower binding .posts 19 which are insulated from the front plate 15 by mica washers 20 or other suitable means. A porcelain bushing 21 is positioned in the body plate 12 near the lower portion thereof and current conducting wires22 are extended through the porcelain bushing 21 and connected with the first and last. lower binding posts 19, as shown in Figs. 2 and 3. Hollow porcelain tubes 23 are suspended between the corresponding upper and lower binding posts 19 and are supported in position by the turns or coils '24: of the heating element or wire 25. By
i has its coils wound around the porcelain -tion.;
that the heater may beemployed whenever tubes 23 with the upper and lower turns of each coil extended through suitable openings 26 near the upper and lower ends of the porcelain tubes 23. The wire or heating element 25 is extended across the binding .posts 19 to connect the same in pairs between the porcelain tubes 23, first at the upper ends of the latter and then at the ipwer ends thereof, as shown clearly in lositioned in front of the Wire or heating element 25 and the porcelain tubes 23 is a grating which includes upstanding bars 27 mounted across horizontal or longitudinal bars 28, which latter have their ends 29 bent back and then offset outwardly to form fingers 3O engaged in recesses 31 in the end plates 10. This is clearly shown in Figs. 1, 2 and 4 and it will be evident from these views that the grating will serve to protect the porcelain tubes 23 and the element or wire 25, as well as the binding posts 19. Furthermore, the grating will prevent plac ing of the heater too close to furniture or any other article. the front plate 15 will serve to reflect the heat rays from the element or wire 25 upwardly and downwardly as well as outwardly and at the same time serve as a firm support for binding posts 19 on which.
the heating element or wire with the porcelain tubes 23.
The body plate 12has an air opening 32 in its lowermost portion and a handle 33 mounted on itsuppermost portion and insulated therefrom by suitable insulating washers 34 carried on the fastening membars 35 employed for attachin the ends of the handle 33 to the top 0 the body plate-12. Therefore, the handle 33 may be employed for lifting and carrying the heater when the same is in use, without danger of burning the hand engaged with the handle 33. v
It is believed the complete construction and operation of the heater may now be apparent from the foregoing paragraphs taken in connection with the accompanying drawin 5 without further detail descript may be briefly stated, however,
25 is suspended desired and: the ;wires 22 connected with service wires or distributing wires, by
It is also apparent that with the main While the preferred embodiment ofthe invention has been disclosed it is to be understood that minor changes in the details of construction, combination and arrangement of co-operating! elements may be resorted to within the scope of what is claimed without departing fromthe spirit of the invention.
