STEAM-COOKER.

Specification of Letters Patent.

Application filed March 21, 1906. I Serial No. 307,204.

To all whom it may concern.-

Be it known that we, CHARLES S. EPPLEY and MERVIN E. STONESIFER, citizens of the United States, and residents of York, in the county of York and State of Pennsylvania,

have made certain new and useful Improvements in Steam-Cookers, of which the following is a specification.

This inventionis animprovementinsteamcookers intended especially for domestic use; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a vertical longitudinal section from front to rear of a cooker embodying our improvements. Fig. 2 is a transverse vertical longitudinal section of the cooker. Fig. 3 is a bottom plan view thereof, partly broken away. Fig. 4 is a perspective view, partly in section, of the boiler; and Fig. 5 shows a somewhat different form of boiler or generator from that shown in the' other figures of the drawings.

As shown, the cooker comprises a casing A, divided by a horizontal partition B into an upper steaming-compartment C and a lower baking-compartment D, provided, respectively, with doors C and D, by which access may be readily had to the different compartments. The bottom D of the compartment D is elevated or raised above the bottom of the casing, affording boiler-space D beneath it for the heating branch E of the boiler E and for the bottom plate F of the casing, which forms, with the bottom D the boiler chamber or space D at the bottom of the casing in which the heat accumulates surrounding the said heating branch E, 'as will be understood from Fig. 2 of the drawmgs.

The boiler is of a special cross-sectional shape, as will be described, and it is spaced at e and c from respectively the plates F and D so the heat may circulate entirely around the heating branch E of the boiler, as best shown in Figs. 1 and 2 of the drawings.

The bottom plate F of the casing is provided with openings f, through which the, heat may pass into the boiler-chamber D and has a plate f separating the openings f and extending beneath the heating branch E of the boiler in such manner as to protect the same y from the direct action of the heat upon which the cooker is placed in practice, and the heat passing up through the openings f may circulate freely around the heating branch L of the boiler to quickly raise the water therein to a steaming-point.

Flues G and G extend upwardly from the boiler chamber into the baking compartment and discharge heat thereto. By preference the flue G is elongated. from front to rear and distributes the heat evenly at one side of the baking-compartment, while the flue G is in the form of a pipe having a returned upper end G and arranged at the opposite side of the baking-compartment from the flue G, as will be understood from Fig. 2 of the drawings.

The boiler E has the horizontal or heating branch E and the uprightbranch E communicating at its lower end with the rear end of the branch E and extending thence up through the bottom D of the baking-com partment and opening at its upper end into the bottom of the steaming-compartment at the rear end thereof, as will be understood from Figs. 1 and 2. By preference the upper end of the upright branch E is flanged at 6 along the upper side of the bottom B of the steamingcompartment C and may be soldered or otherwise secured thereto, as will be understood from Fig. 2 of the drawings, so that the boiler at its upper rear end is secured. to and supported from the bottom B. At its opposite end, or the front end of the heating branch E, the boiler is supported from the casing through the medium of the faucet II, which has its threaded nipple I-I extending through the casing and screwed at H into connection with the front end of the heating branch E of the boiler, whereby to securethe said boiler firmly at such point in connection With the casing. By this construction the boiler is supported above the bottom of the casing, and the weight of the boiler is supported from the bottom B of the steamingcompartment and the lower portion of the front of the casing, as will be understood from Fig. 1 of the drawings.

In constructing the boiler E it is preferred to form its heating and upright wings or sections from sheets of metal bent to the desired cross-sectional form and secured at their meeting edges by rivets, the rivets of the lower or heating section E being at the top from the stove or other heating medium,

thereof and such section having its sides flaring outwardly toward their upper edges, as shown in Figs. 2, 3, and 4 of the drawings.

For filling the boiler we employa tube I, extending down through the top of the cooker and projecting at its lower end into the open upper end of the boiler and preferably extending down, as shown in Figs. 1 and 2, to a point below the upper side of the heating branch E of the boiler.

A removable funnel J fitting in the upper end of the tube 1, facilitates the filling operation, and its funnel may be utilized to secure an alarm-whistle J. l/Vhenit is desired to renew the water in the boiler, the funnel J may be removed, the whistle J withdrawn,

. and the funnel again inserted to direct the water into the tube I.

In Fig. 5 we illustrate a somewhat diiferent form of boiler in which the heating branch designed to be used in lieu of the branch E is composed of front and rearsections K and K, and pipes K connect the same, and the upright branch K connects with the rear sec tion K and extends upwardly, as indicated in Fig. 5, to discharge to the steaming-compartment. This construction may be substituted for the construction shown in Fig. 1

without departing from some of the broad principles of the invention, and it will be understood that when so substituted the faucet may be utilized to connect the front end of the heating branch with the casing, and the upright branch may be supported from the bottom of the steaming-compartment, as described in connection with the upright branch E of the form of boiler shown in Fig. 4.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The improvement in steam cookers herein described, comprising a casing having a horizontal partition dividing it into an up per steaming-compartment and a lower bakingcompartment, said partition forming the bottom of the steaming-compartment, a bot tom for the baking compartment located above the bottom of the casing, the casingbottom plate spaced below the bottom of the baking-com artment and forming a boilerchamber be ow the same, said casing-bottom having openings admitting heat to the boilerchamber and an intermediate plate between the said openings and forming a guard for the boiler, means for conducting the heat from the boiler-chamber into the bakingcompartment, a boiler having a horizontal branch extending within the boiler-chamber and above the intermediate plate between the openings in the casing-bottom and an upright branch or section extending from the rear end of the heating branch upwardly to and discharging into the steaming-chamber and supported at said upper end from the bottom of the steaming-compartment and a faucet having its threaded nipple extending through the casing and screwed into connection with the front end of the heating branch of the boiler, .all substantially as and for the purposes set forth.

2. The combination in a steam-cooker, of a casing having a steaming-compartment and a baking-compartment and provided below the baking-compartment with a boiler chamher and with a bottom plate for said boilerchamber and a boiler having a heating branch extending within the boiler-chamber and an upright branch extending to and discharging into the steam-chamber, substantially as set forth.

' 3. The combination in a steam cooker with a casing provided at its lower end with a boiler-chamber and below the same with a bottom plate having openings and an intermediate plate between the same and a boiler having a heating branch within the boilerchamber and extending above the said intermediate plate and spaced apart therefrom, substantially as set forth.
