Patented Aug. 91910 STEAMER.

Application filed February 3, 1910. Serial No. 541,876."

1'0 all whom it may concern:

Be it known that I, FRANCIS J. Aipnnnci rr, a citizen. of the United States of America, residing at Pittsburg. in the county of Alleheuy and State of Pennsylvania, have iniented certain new and useful improve ments in Steamers. of which the Following is a specification. reference being hail therein to the accompanyina drawing.

This ii'iveution more particularly to that type of steamer used "for generating steam adapted to be. injected in a proofing box or oren during the raising of bread and the baking thereof.

The primary object of my invention is to provide steam-generating apparatus that can be safely and easily operated to quickly produce steam from fresh water. thus avoiding the impurities in steam that is gone atcd .trom water that has stood for some time, as

in large boilers.

Another object of the invention is to provide a portable steamer with a water reservoir positioned to autonuitically feed water to a. coil adapted to be heated by a tianle either from a gas burner or from a coal fire.

A further object of the invention is to provide a steamer of the above type with means as will be hereinafter set forth for controlling the supply of nter to a steam generating coil.

A further object of the invention is to provide a steamer that is simple in construe-- tio'n inexpensive to manufacture and highly efficient for the purposes for which it is intended.

With these and such other objects in view as may hereinafter appear, the invention consists of the novel construction combination. and ar angement of parts to be here inatter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a vertical sectional view of a rnan'crs J. ALBRECHT, or rrr'rsBUnG, rnnnsyiivalviin,

metal having the edges thereof overlap} I p and connected. as at 2. Thecylindrical shell has the lower end thereof provided with legs ladapted to slipport tlie an elevated position above a gas-burner but when thesteanier is to be used" nection with a coal tire. the'lower end'o'f shell 1 is provided with a flaring ha;

best shown in Fin. 2 of the drawing;adapt (m ed to support the shell 1 upon the "c the lir'c. The upper end of thcsliel provided with an inwardly projecting fl and pivotally connected to said lug rivet or pin (3 is a lidT adapted to clo upper end of the shell. This l v 'vided adjacentto ondedge with aii open M 8 and with a slot 9, and theobject' of both will presently appear. i 3 The shell 1 is provided with:in intgrior lining); of asbestos 10 or otherfireproof n; terial. and said shell inte'rmediate"the I thereof is provided witlr inwari'llyi projetttt ing brackets 11 adapted to supported 6 or reservoir 12 containiiugwatt-1*l2 v Pl'1e80' tank or reservoir 12 is cyliudi' ical a'nd ol ll less diameter than the shell 1. thc' tank reservoir being; supported cccentricallv wit in the shell .1 to provide a space '12 b side of the shell, bcti'vcen the innersideof 35 the shell and the outer sideot theQtluik' reservoir 12.

Extending into the bottom of the tankor reservoir 12 is a pipe 14.- having' the upper end thereot provided with an ell )ow"'l5 "co'nnected by a pipe 16 to an elbow 17, the lower end of said'elbo'w extendingdnt'o proximity to the bottom of the tank or reser voir 12. In the elbow 17 is mounted ninth-L ing 18 having a central opening 19. Adapted to close this opening is a gravity valve or spherical body 20, the object of which will presently appear. The lower end of the pipe 14. is connected by an elbow 21 to the lower convolution 22 ot' a coiled tube 23 located in the shell 1, between the lower end of the tank or reservoir 19 and the lower end of the shell. The uppermost convolution 24- ot the coil of tubing'is connected by an elbow 25 to a stand pipe 26, said pipe extending upwardly.betwcen the shell 1. and the tank or reservoir 12. The pipe is adapted to extend through the slot 9 of the lid 7, the slot 9 being disposed at an angle to permit of the lid being swung open without interfering with the stand pipe 26.

Mounted upon the upper end of the stand als of pipe 26 is a valve body 27 having a hot 1 medium of this valve that the Water'within water Outlet pipe 28 located above the open- I ing 8 of the lid 7, said valve body also having an elbow 29 connecting with a steam outlet pipe' 30. In the valve body 27 is a valve plug 31 having ports 32, 33, and 34. The valve plug is retained within the valve body by a washer 35 and a nut 36 at one end of the plug and at the opposite end thereof is provided with a handle or crank 37 The ports 32 and 34 are adapted to establish communication between the stand pipe 26 and the steam outlet pipe 30, while the ports 33 and 34 are adapted to establish communication between the stand pipe 26 and the elbow 29 with the side of the valve ph g closing the hot Water outlet pipe 28.

hen gas is utilized as a beating medium, pieces of wire 35 or other heat retaining and conducting materlal can be placed centrally of the convolutions of the coil oftubing, whereby the heat from the as burner will be retained and properly disseminated relatively to the coil of tubing. The heat retaining and conducting material can be dispensed with when a coal fire" is used. p

When the tank or reservoir 12 is filled With Water or nearly so, the Water raises the gravity valve 20, fillsthe coil of tubing 23 and assumes a level Within the stand pipe26 corresponding to the level of the Water With- I Y in the tank or reservoir 12. When the coil of tubing is subjected to the action of a flame, either gas or coal, the water within 20 will then open and allow a quantity of Water to enter the coil, and it is through the the tank is automatically fed to the coil.

The shell 1 is provided with a suitable bail 40, whereby the steamer can be easily carried-from one location to another, for instance, from a proofing boXto an oven. I

I attach considerable importance to the fact that the reservoir or tank 12 can be easily cleaned. and from'time to time filled with pure water, consequently the steam generated from the water will contain a minimum amount of impurities and thereby prevent the steam from injuring the bread with which it contacts.

While in the drawing there are illustrated the preferred embodiments of my invention, it 1S to be understood that thestructural without departing from the spirit and scope of the invention.

, elements thereof can be varied or changed Having now described my invention whatof water from the coils to the tank, the upper end of said tubing provided with a vertical stand pipe located within the casing and projecting beyond the top thereof, a three-way valve mounted upon the end there of, a return pipe connectin with said valve directing a return of the uid to said tank through said apertur-ed cover, a steam outlet pipe connected to said valve, and a heating means arranged below said tubing, substantially as described.

in testimony whereof I aflix my signature in the presence of two witnesses.
