Specification of Letters Patent. Patented Dec. 14, 1909 Application filed April 16, 1909. Serial No. 490,256.

, To all whom it may concern.

Be it known that I, HENRY P. KnoBLoon,

' a citizen of the United States, residing at Pittsbur'g,.in'the county of Allegheny and 'The invention relates generally to an im- .pr'ovement in toasters, and 131110138 particula'rly directed to a construction in the use of 'which a plurality of pieces of material may 'be simultaneously subjected to the action of the heat, the radiation of such heat being controlled to insure its uniform distribution to the full exposed surface of such material.

. The main object of the present invention is the provision of a toaster provided with a series 'of material supports, which supports -'are removably connected tothe toaster to' permit the use of the latter for purpose other than toasting.

A further object isthe provision. of a bafiie plate for distributing the heated gases, which plate is of solid construction and secured in a novel manner in the toaster.

The toaster as an entirety, withthe exceptiou (ii the material supports, is constructed of sheet etal and the parts are so arranged as to be $36. 3.} assembled without the usual soldering or riveting, thereby facilitating the construction and reducing its cost to a {a series of openings 11,'and the edges thereof minimum without impairing its efficiency.

The invention will be described in the following specification, reference bein had particularly to the accompanyingdrawings. in which Figure l is a plan of a toasterconstructed in accordance with my invention. Fig. 2 is a horizontal section of the same. Fig. 3 is an elevation, partly broken out, of the same. Fig. 4 is an elevation of a slightly modified form of toaster. Fig/5 is a vertical central section of the same. Fig. 6 is a horizontal section of the same. p

Referring particularly to the accompanying drawings, my improved toaster, in the form shown in Figs. 1, 2, and 3 comprises. a base 1 preferably rectangular in plan. The base is constructedof sheet metal with its edges bent to provide-upwardly projecting flanges 2, whereby the base is of pan-likev formation particularly arranged to receive and support any refuse or the like whichv may fall from the material being toasted or cooked. A radiator 4:, which in this-form of the toaster is of conical formation, is arranged centrally of the base and comprises a strip of sheet metal bent into proper -form with its meeting edges appropriately secured to maintain the form. The lower edge of the radiator is provided with a series of tongues e which are designed to pass through openings the base and to be bent intocontact with the lower surface of the base to secure the radiator in position.- The base within the plane of the lower edge of the radiator is formed with an opening 7 through which the heated gases reach the radiator, the normal diameter of-this opening being slightly less than the diameter of the lower end of the PitdlfltOlQ tO provide an annular flange of the base extending within the radiator. This flange in the completed article is turned up into contact with the inner surface of the radiator, as at'8, thereby further supporting ltheradiator 'in position. A head plate 9 is supported at the upper end of the radiator, said head plate correspondingin outline to the outline of the base but being of less length and breadth than the same. The upper edge of the radiator is provided with tongues 10 designed to. be, passed through openings in the head plate and to be bent into contact with the upper surface of said plate to secure the head plate in position. The head plate is formed with are each formed to provide a centrally arranged projection 12, for a purpose which will presently appear. The radiator through,- out practically its entire surface is formed a with a series of slitted openings 13, arranged in concentric rows and in spaced relation circumferentially of the radiator, these opepings being preferably formed by punching through from the inner surface of the radiatonf The openings gradually decrease in length from the openings ofthe lowermost row to the openings of the uppermost row. lVit'hin the radiator, in the form illustrated in Figs. 1, 2, and 3, is'secured what I term a bathe plate 14, comprising an imperforate circular section of sheet metal upwardly curved from its peripheral edge to provide 'a member of approximately 1n-. verted dish-shape. The peripheral edge of the bafiie plate is provided with a series of the ham-e P a e .in place,.-are designe-d'w passed through certain openings 13 of any selected series, the ends of the tongues being I turned down beyond the radiator. The plate is inserted in such relation to the radiator as to provide a space between the tion when desired. A material support 16.

is provided for each side of the toaster, said supports being of duplicate construction and each preferably formed of a single 15 length of material, as wire. The support is bent intermediate its ends to provide a cross bar 17 and projected from the ends of the cross bar to provide parallel uprights 18,.

being bent at the terminals of the uprights go to form curved rests 19. Fromthe ends of the rests the-material of the supports is pro ected downwardly, as at'20, and then laterally to form'hooks 21. -Each support is secured in place by removably seating the cross bar 17 "thereof in an open roll or loop 22 formed by suitably bending the extension 12' of the head plate, and in passing the vertical portions of the hooks 21 through openings 23 formed in the base plate immediately adjacent theflange-,2 thereof. The parts of the support are of such relative lengths and positions that when in place the uprights 18 extend downwardly in approxiilnate parallel relation to and in spaced rela- 35, "t1on with the surface. of the radiator, the rests 19 being disposed above and immediately over the base plates' The vertical por-.

:tions- 20 of'the uprights lie wholly beyond the edge flange 2 of the base, so that the hook passes around said flange and enters the-opening 23 from beneath. As the supports are of spring material it is obvious that they may be readily disconnected from the toaster proper when desired, and further that the flange 2 bearing against the upright ortions 20 of the supports serves to matenally increase the rigidity of the support in. use, as will be clearly apparent from an inspection of Fig. 3 of the drawings. If found desirable to more perfectly support combustion the upper portion of the radiator may be formed with a-series of openings 24, as more clearly shown. in Fig. 3.

In Figs. 4:. 5, and 6 I have shown a 5 slightly modified form of toaster, in which,

however, the description hereinabove rcla E tive to the'base, material supports, and the head plate, will apply as such partsare identical with those described with the other form. In this form, however, the radiator 25 is of rectangular shape in cross section with the walls converging from the base of the toaster to the head plate. With this form, in' the event the material supports 16 6 are removed various articles, such as smooth i'ng irons or the like, may be rested directly against one of the plain" walls of the radiator for heating. In this formalso the baflle .plate diiiers from the previously described bafile plate, in that) the former is integral with the base 1. To this end the central portion of the base is cut out to leave a centrally disposed rectangular. section 26'con nected with the base plateby diagonally alined tongues 27 By means of a suitable'die in the formation of the base plate of the toaster the section 26, which is the battle plate, is offset from the plane of the base plate and preferably given an upwardly rounded or inverted dish-shape. The material of the tongues yielding under the action of the die so as to dispose the batlle plate proper at the required height within the 'radiator.- In connection with the integral baflle plate it is to be understood that the section 26 or baflie plate proper corresponds in. shape to the sectional configurationof the radiator and that while I have shown the integral plate as in use with the toaster having a 4 a radiator of rectangular shape in section, it 90 is to be understood that such formof plate may be as readily used with the toaster in which the radiator is of circular form in section, though in this event the section 26 would be of circular shape inplan. I contemplate the use of either form .of baflie plate with any sectional shape of radiator, and also theformation of the radiator in any sectional outline.

The use of the toaster will be obvious from the above description taken in connection with the drawings, the bread or other material being arranged on the supports in position approximately parallel to the wall of the radiator, and receiving direct and radiated heat distributed by the battle plate to insure an even and perfect toasting of the exposed surface.

It is to be particularly noted that the various parts of the toaster are assembled without riveting or soldering, and that when individually constructed as described may be readily assembled without the use of par.- ticular tools in an expeditious manner. Provision is thus made for a thoroughly eiiicient article in which the cost of production is reduced to the minimum and the construction materially simplified.

Having thus described the invention what l is claimed as new, is

1. A toaster coi'nprising a base, a radiator secured to the base, a head plate secured to the upper end of the. radiator, and material supports rcmovably connected to the head plate and to the base, each of said supports 1 comprising a single length of mater al bent to form a cross bar adapted to removably engage the head plate, projected from the crossbar to form material rests, and pro- M l je'cted from said rests to form hooks to be passed around the edge of the base plate and engage openings formed in said base plate from beneath.

2-. A toaster comprising a base having an upstainling'edge flange, a radiator secured on the base, a head plate secured to the upper end of the radiator, and material supports reniovabl connected to the head plate and to the base, each of said supports i11-' eluding a vertically extending portion terminating in a hook, said hook being adapted to he passed around the edge of the base toengage openings formed in said base plate from beneath, the vertical portions of the supports bearing directly against the outer 15 surface of the base flange.
