ELECTRIC HEATER.

Specification of Letters Patent.

Patented July 30,1912.

To allfwhom t may concern.'

Be it known that I, ROBERT M. MILLAR, a subject of the King of Great Britain, now residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electric Heaters, of which the following is a specification.

The invention relates in general to an electric heating device particularly adapted for making toast and has for itsobjects the provision of an improved utensil with high etliciency vfor performing the functions which it is intended to perform, and to provide a device which may be produced economically, and the parts of which are simple and easily cleaned or replaced. l

More specifically, the device consists of a body portion, the bottom and sides of which are produced from a single piece of inaterial and having a removable pan forming a support for the lower edges of the toast and performing the additional function of catching crumbs. In utensils of this general character there is a liability for the toast to bec-omc scorched atits'center and insutliciently toasted at its side ed es, but I have found that by so winding t e resistance wire upon its supportwith the coils of the wirev tapering from the centery of the support from large to .smaller coils, an even distribution of heat throughout the entire Asurface of the article to be -toastedis hereby procured. p

Other objccts'of the invention will appear more 'fully throughout thespecificat-ion.

the device along the outer edgesl of the end In the accompanying drawing, Figure 1` is a front elevation of an electric'toaster embodying my invention. Fig. 2 is a'v section on 'the line 2 2 of Fig. 1. Fig. 3 is an end viewl of Fig. 1. Fig. 4 is a sectional view of one of the terminals. Fig. 5 is a perspective View ofthe handle.

.Referring now more particularly to the drawings, the body 6 of the device consists of a single piece of metal bent to form the base and

end walls

7 and 7 which are tapered from one end and having the larger ends at the bottom. Secured to the base are four porcelain feet 8. A' series of cross bars 9 are horizontally disposed on both sides of

walls

7 and 7*1 to serve as a support for the article to be toastedand revent it from coming in contact with the eating medium.

formed into two units or

sections

11 and 11,

each unit or section consisting of a series of coils turned about thev insulating supports 12 and ,12a which are of some material such as mica, or the like. The coils composing. the sections or units 11 and .11'1 are gradually spaced from thecenter toward. each end, the space 'between thel coils being the greatest at the center and gradually diminishing from both sides of the center coil, thereby providing a uniform distribution of heatupon the surface to be heated. The two ends of the resistance wire 10 are connected to suitable terminal posts 13, each post consisting of two parts having screw threaded engagement; the part'13a having a suitable slot 14 formed transversely through it near one end through which the resistance wire is adapted to pass and to be held therein by means of' a screw 15 havlng a threaded engagement with the internally threaded section 13=I of the posts 13. Sultablemica washers 1G are interposed between the two parts of -the terminal posts and the ends 74 and 7a so as.t0=insure the proper insulation between such parts. The

' insulating supports are held in their proper and 17a, each `having a longitudinal slot 18 v in which the insulating supports are slidably 4mounted and which are normally held in position by means of screws 20. A deflector plate 21 rests on top of the bindlng posts and is secured thereto by means of suitable screws 22. The deflect/or plate is curved so as to conform to the contour of-v thenarrow tapered ends of the end walls 7 an a.

To support the article to be toasted I provide a removable tray 23, so bent as to allow it to pass under the lower insulating support 12, and resting near its ends upon the two lower cross bars 9; the edges ofthe tray projecting beyond the side walls of thev body portion forming supports 24 for the article to-be toasted. The tray is adapted to catch all crumbs falling from the toasted article and as it is easily removable it can.I

body of the bread resting against the cross bars 9 and against the lower edge of the defiector plate 21, and with the slde edges of the bread resting either againstA or near the edges of the end walls of the device, that a chamber is formed about the heating me-r dium, whereby theheat is retained within the device and the article is toasted much quicker than when the heat is not so con fined.

To move thedeviee about I provide a handle 25, which is lpreferably formed of a single piece of wire having its ends bent forming fingers 26 adapted to enter the apertures 27. The handle is applied by bringing the body of the same into a Ver-. tical position and inserting the fingers 26v in the apertures 27 as far as the shoulders l. An electric toaster comprising a base The handle is then brought down intol and end walls formed from a single piece of material, a resistance wire, insulating supports therefor, and binding posts secured to the end walls, each post having a longitudinal slot in which said insulating supports are slidably mounted.

2. An electric toaster comprising a base and end walls formed from a single piece of materiala resistance wire, insulating supports therefor, binding posts carrying said insulating supports, cross bars horizontally disposed between the edges of said side walls anda removable tray adapted to lie under said resistance wire and having its outer edges resting on the lowest opposite cross bars.

3. An electric toaster comprising a base and end walls formed of flat sheet material, a resistance wire, insulating supports therefor, binding posts carrying said insulating supports, a removable tray disposed beneath said resistance wire and having its side edges projecting beyond the edges of the side Walls for supporting the article. to be toasted, and a curved plate between said side walls and above said resistance wire.
