STEAM-COOKER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed August 6, 1909. Serial No. 511,628.

To aZZ whom it may concern:

Be it known that I, lVILLiAM A. C. MURPHY, a citizen of the United States, resident of Springfield, in the county of Greene and State of Missouri, have made a certain new and useful Invention in Steam- Cookers; and I declare the following to be a full, clear, and eXact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l is a perspective View of the invention with the cover of the cooking chamber thrown back. Fig. 2 is a central vertical longitudinal section of the invention. Fig. 3 is a cross section of the invention taken through the cooking chamber. Fig. t is a detail perspective view of the cooking chamber.

The invention relates to steam canners and cookers, or to steam cookers particularly adapted for canning purposes, and it consists in the novel construction and combinations of parts as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter a, designates a furnace or combustion chamber, open at the top and having a door for insertion of fuel, and a stove pipe connection.

The upper part of the furnace is divided into two compartments by a partition b, a scalding vat c, fitting in the smaller compartment and a steam cooking chamber (Z, fitting in the larger compartment, both scalding vat and steam cooking chamber having lateral supporting flanges c', and cZ, respectively, extending around the same and closely engaging the upper edge portions of the furnace, suitable packing strips e, being employed to make the fit smoke and gastight. The flange c', of the scalding vat and the adjacent flange fZ, of the steam cooking chamber both engage a groove Zi, of the partition b, also having packing strips e.

The steam cooking chamber is divided into two parts upon an oblique plane, extending upward froin one end or side, the lower part f, being adapted to contain the can trays or supports and cans, which project partly above the top thereof, while the upper part f', which forms a large portion of the chamber, is hinged at its smaller end to the lower part at g, being capable of tuiiiing back upon its hinges to leave the can trays or supports and cans partially exposed and readily accessible, as shown in Fig. l of the drawings. A groove Zt, is formed around the upper oblique edge of the lower part j', of the cooking chamber, the lower oblique edge portion Zt, of the upper part f, of said chamber fitting closely in said groove, suitable packing strips z', being eniployed to make the joint steam-tight.

The lower body portion f, of cooking chamber (Z, is provided with downward eX- teiidiiig water legs eZ, (Z2, at each end, piojectiiig into the furnace for better heating effect.. Upon the bottoni of this chamber joining said water legs rests a platform support y', having legs and piojectiiig at the ends over the water legs (Z2, (Z2, and having openings j', j', for admission of the rising steam. Upon this platform rests a shallow' tray Zt', having perforations Zc, Zu', in its bottom and adapted for the reception of a number of cans the contents of which are to be steamed or cooked. Upon the cans in the tray Zt, is placed a second perforated tray Z, similar to the tray Zt', and adapted also to receive cans of material to be steamed, a third and similar perforated tray m, being shown as resting upon the second series of cans and receiving in its tui'n a load of cans. A fourth tray m, is also shown. This loading of the steam cooking chamber with cans -tier upon tier is conveniently accomplished owing to the division of the chamber obliquely into two parts, the upper cover part forming a large portion of the chamber, leaving when thrown back the contents of the low'er body part exposed and accessible and rendering easy the insertion of the various trays and cans without interference with the side walls of the body part, three of said side walls being at the saine time left of sufficient dimensions to form a limiting stop or abutment for the trays of the several layei's or tiers.

The body part of the steam cooking chamber is partially filled with water, which fills the water legs and partially fills the platform support. When the cover is low'- ered a steam-tight joint is formed between the same and the lower body of the chamber, owing to the close joint and the packing strips before referred to, added to the weight of the cover. Perforations a, n, are formed in the upper side portions of the cover for with a Small number of cans or in facto-l ries with a large number. It is not necessary to ll the various trays with cans, and

one, two or more layers of cans with ytrays may be used as desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. In a steam Cooker, a cooking chamber having a lower body member, and an upper hinged cover member composing the major portion of said chamber and having oblique meeting edges in a single plane extending upward from the bottom portion of one side and terminating intermediately of the height 1 of the opposite side, one of said members having a grooved edge portion and the other member having its meeting edge portion closely engaging the same in a steam-tight manner.

2. In a steam cooker, a cooking chamber having a lower body member and an upper cover member having oblique meeting edges ,extending upward from the bottom portion of one side and terminating intermediately of the height of the opposite side, said meeting edges having a steam-tight engagement, said body member having downward extending water legs, and a platform support having downturned edge flanges resting upon the bottom of said body member and extending at its ends over said water legs.

In testimony whereof I affix my signature, in presence of two witnesses.

WILLIAM A. C. MURPHY.
