Specification of Letters Patent.

Patented Dec. 9, 1913.

Application filed May 20, 1912. Serial No. 698,386.

To all whom it may concern:

Be it, known thatI, ALonzo A. WAnNnn, acitizen of the United States, and a resident of New Britain, in the county of Hartford tion of a toaster embodying my inventions Fig. 2' is an end- View with parts be ng.

broken away to show construct-ion. Fig. 3 is a sectional plan view of a portion of the device taken on the line a: of Fig. 1. Fig. 4 is a sectional side view of the parts shownin Fig. 3.

Referring to the drawings a denotes the base which is preferably made of sheet metal provided at its ends with feet in the form of disks 2 located between the outturned ears 3 and secured by the pins 4. The disks may be notched as at 5 so as to project slightly above and engage the edge of the base. This is an inexpensive and extremely satisfactory structure for finishing the base and providing suitable foot pieces. If desired, these disks can be made of insulating material.

On the base is secured a standard 10 formed from sheet metal and which constitutes the support for the toaster proper. At either end of the standard a lip 11 is turned up. The frame 15 of the toaster is of inverted U shape with its side arms lying against these upturned lips 11. Fitted against the inner faces of the side arms of the frame are

plates

16, 16 secured at the top as by the

screws

17, 17, slotted along the median line as indicated at 18, and preferably corrugated at this point as clearly seen in Figs. 3 and 4: The ends of the frame arms and the lower ends of these plates are secured to the lips 11 by the clamps 12 and screws 13, binding the structure together and of a wire coiled about acore of insulating material. The cores which are the same in each section of the unit can conveniently be made of layers of mica 22 stifl'ened by a strip' of metal 23 passing centrally through them between the layers. The ends of these cores are seated in the grooves 18 in the plates. 16, and by corrugating the plates in the grooved part, a deeper bearing for the ends of the cores is secured as clearly seen in Figs. 3' and 4.

The sections of the unitsare arranged one above the other spaced apart slightly and connected together by the links 34. The resistance wire 25 is wound more closely on the lower section 20 than is the resistance wire 35 on the intermediate section 30, which in turn is more closely wound than the resistance wire 45 on the upper section This may be one continuous wire starting at one terminal and wound' successively upon the separate sections, and then brought back to the other terminal 51, or they may be separate wires joined together in some convenient way. This is not material so far as certain features of the invention are concerned.

Guard wires pass through apertures in jthe top of the frame, and their ends enter apertures in the standard; This keeps the bread, or other material, from lying directly against the unit and so prevents burning. ;

Holders

56, 56 are pivoted on cross bars 57 near the bottom of the toaster and are pressed by the springs 58 against the frame The resistance as illustrated is in the form with the result that they hold the bread closely against the guard wires. These holders can conveniently be made by bending up a wire to shape, as clearly illustrated, providing it with the inturned projections 59 to receive a cross bar (30 made'of sheet metal with portions folded over at each end to keep the material evenly pressed against the lard wires. A base 61 attached to the sides of the holder forms a bottom support for the material which is being toasted. A top 70 is provided with depending spring arms 71 channeled at their ends to slide on the frame, and apertured to receive the heads of the screws 17 which constitute holding and positioning devices. This top prevents the too rapid escape of heat, and can conveniently be used for keeping toast and other materials warm.

WVhile I have described the illustrated embodiment in. detail, nevertheless I do not wish to be understood as limiting myself to v the exactconstruction shown and described,

but on the contrar desire to claim protection'for any modi cations which may come within the spirit of the invention.

I claim as my invention 1. In a device of the character described,

a base, a frame supported thereon, a sectional heating unit mounted in the frame, the sections of said unit being of similar shape and arranged closely together edge to edge in the same plane, with the adjacent edges of said sections'approximately parallel, and means for electrically heating the lower part of said unit to a greater extent than the u per part thereof.

2. In a evice of-the character described, a base, a frame mounted thereon, a sectional heating unit supported in said frame, the 'sections being arranged one above the other in the same lane with their adjacent edges arranged c osely together and approximately parallel to one another, said sections comprising cores of insulating material with a resistance wire wound thereon, the number of turns of said resistance material on the lower section being in excess of the number of turns of the resistance material on the upper section.

3. In.a device of the character described, a base, a frame supported thereby the sides of said frame being longitudinally corrugated and slotted in the top of the corru ation, and a heating unit comprising a in wide core whose ends are adapted to fit within the slots and a resistance material mounted on sai core.

4. In a device of the character described,

a. base a frame of inverted U-shape having its sid e arms secured to thebase at their ends, longitudinally corrugated and slotted plates secured to the inner faces of said side arms, and a sectional heating unit supported I in said frame, said sections being arranged one above the other, and each section comprising a thin wide core whose ends are adapted to fit in the slots and resistance material mounted on the core.

5. In a device of the character described, a base, a frame of invertedU-shape having its side arms secured to the base at their ends, longitudinally corrugated and slotted plates secured to the inner faces of said side arms, and a sectional heating unit supported in said frame, saidsections being arranged one above the other, and each section comprising a thin wide core whose ends are adapted to fit in the slots and a resistance Wire wound upon said cores, said wire being wound more closely upon the lower core a than upon those above it.

6.. In a device of the character described, a base, upturned li s at the ends thereof, a frame of inverted -sha e having the ends of the side arms locate means for clamping said arms to said lips,

against said lips, i

and a heating unit supported by, said frame.

7. In a device of the character described, a base, u a frame of inverted U-shape having the ends of its side arms located against said lips,

plates secured to theinner faoes'of the side arms, clamps to secure said plates and arms turned lips at the ends thereof, 1 I

to said lips, and a heating unit-supported in said pla ALONZO A. WARNER. Witnesses:
