Application-filed April 29, 1921. Serial No. 465,535.

To all whom it may concern:

Be it known that I, GEORGE W. BAKER, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Self-Leveling Stoves for Ships, of which the following is a specification.

This invention relates to stoves, and the primary object of the invention is to provide an improved means for supporting a stove on board ship, so that the stove will be self leveling at all times, irrespective of the roll of the ship, thereby eliminating the inconveniences usually experienced, by cooks cooking on ordinary cook stoves during rough weather.

Another object of the invention is the provision of a novel cradle for-receiving an ordinary ship stove, and a novel means for suspending the cradle" so that the stove will be free to rock back and forth during the rolling of a ship, so that the top thereof will always be in a horizontal plane.

A further object of the invention isvthe provision of a novel joint for the stove and pipe, so as to permit the free passage of the products of combustion from the stove during the swinging motion thereof, the joint for the stove and pipe being in direct hOYl: Zontal alignment with the pivot joints for the cradle for supporting the stove. A still further object of the-invention is to provide a novel me'ansfor suspending the cradle so that theentire stove will be below the pivot points thereof, whereby the weight of the stove itself will-tend to hold the stove in a level position, thereby obviating the necessity of providing a weight for the bottom of they stove as heretobefore contemplated in other level seeking devices.

A still further object of the invention is to provide an improved cook stove of the above character,whichwillbe durable and eflicient in use, one that will be simple and easy to manufacture, and one which; can be placed upon the marketat a reasonable cost WVith these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated, in the accompanying drawings, forming a part of this specification, in which drawings:

Figure 1 is a side elevation of the cook stove, showing the same arranged in the novel cradle provided therefor.

' Figure 2 is a front elevation of the cradle with the cook stove therein.

Figure 3 is a rear elevation of the cradle with'the cook stove therein.

Figure 4 is a top plan view-ofthe same.

Figure 5 is an enlarged vertical section through'the novel stove pipe connections for permitting the stove to rock to'and' fro so as to be normally held in a horizontalposition during the rolling of the vessel.

Figure 6 is a similar view showing the position of the joint when the vessel has rolled to its limit of movement.

F igure? is a vertical transverse section through the improved joint.

Figure 8 is an enlarged horizontal section through a portion of the frame and stove illustrating the clamp for engaging the stove to hold the same against accidental movement in relation to the cradle.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the improved means for suspending a cook stove Bin a galley C of 'a ship. D indicates the novel joint for the stove B and its stove pipe.

The stove B may be the usual or any preferred type of stove, and as shown consists of the body 10' having the side walls 11, the front wall 12, the rearv wall 13, the top 14 and the bottom wall 15. Thetop 14 is provided with the usual cooking hole openings which are adaptedto be closed by the stove lids 1'6 and the flue 16, to which is attached thereof. The transversely extending rods 20 are connected to pairs of vertically extending supporting rods 21 arranged on opposite sides of the stove by means of elbow joints 22. If so desired the frame A ma be formed outof piping, or the like, but 1t is to be understood that other material may be used and that the rods can be IIIZLClG SOllCl if so desired. The vertical rods 21 areeonnected at their upper ends. to longitudinally extending rods 23 by means of cross shaped joints 24 and these joints 24 may; have coni nected thereto U-shaped rods25 the upper horizontal portion. 26 of which may form end -rails for the stove. The forward ends of the longitudinally extending-rods23 haveconneoted thereto a front transversely ex- 1 tendingsupporting rodor bar 27, andfthis i hold the stove B-against movementin the frameorcradle A, adjustable clamps 34 are slidably mounted on eachone of the longitudinally extending rods 23 and these clamps are held in their adjusted positions by means i of thumb-screws 35, which are adapted to impinge against :the longitudinally extend ing rods 23. These clamps 34 are each provided with lugs 36 which' are adapted to engagethe corners of the stove This effectively holds the stove against movement inrelati'onto the frame.

The-necessity Of 'feet forthe stove is entirely eliminated," and the stove=is not bolted to the deck of the ship as in the usual stove construction, as the cradle permits the stove toswingduring the rolling of the vessel.

The cradle is suspended in anovel manner which will nowbe-describechso as to permit the swinging of the stove.

-A supporting post 37lis provided and as shown this post 37 is securedat its lowerend tothevessel, but it is tobe understood,

however, thatif it is so desired; this post may be suspended from the de'cki The-post 37 is disposed'in rear of the stove, soas not 7 to interfere with the moving-of pots-and pans on the stove; andth'e upperend of the post maybe braced by rearwardly extending brackets 38 which'may be bolted or otherwise connected to onewall of the galley C. The rods or bars 33 are-adapted toembrace the opposite sides-'ofthe post 37 sjoas to prevent' ,relativet lateral movement of the framein relation' to thepost, and" these bars 33'form-a-guide-for the cradle or frame d11ringthetransver'se swinging thereof. One

oftlr e bars orrods-33 has i secured Ethereto the upwardlyextending"triangular= shaped bracket 39 and the upper end. of this bracket has its apex portion disposed above the upper surface of the stove adjacent to the longitudinal center thereof and is pivotally connectedby means of a pivot bolt or the liket40..to the post 37 adjacent to the upper end thereof. The forward rod or bar 27 has a .centrallydisposed cuff or clamp -plate41 secured thereto, and this clamp plate or cup is initu'rn-pivotally connected by means of numeral 45 'isalso indirect alignment with the "pivot'b'olts 40 and 42 and this joint is so constructed-as to permit the freepassage of the products-of combustion from the stove to theatmosphere.

The joint D comprises a -lower stationary section 46 and an upper socket section 47. The lower stationary section 46 includes the side plates "48 and *the end curved plates .49, which form a part of a circle. The-lower end of the stationary section 46 is provided with a thimble 50 for receiving the flue 16''. The upper ends of the end walls 49 are spaced to form thesmoke outlet. The attaohing V thim ble" 50' is; provided with} the diametrically extending slo'tted ears 52, which are adapted to receive suitablebolts 53, I or the like/for connecting Ithei same rigid-ly'to the stovefltop '14. 7

The upper socket section '47 is formed relatively larger than the lower section 46 and-is so constructed that irrespective of the position of the two sections, the smoke and other products of combustion will have unimpeded passage fromth'e stove-to the atmospherea Asshownithez-upper socket section 47 includes the side plateseorwalls'54 and the arouate end plates 55.; .The side plates 54 are adapted. to extend 5 on opposite sides of the side plate' 48" of ,theflower removable section 46 and thelowerf ends of the end walls-55 are adaptedtosnugIy engage the outer= surface of-the end walls- 49 at alltimes', so"asto preventrthe escape of smoke between the lower section=46-andfthe upper section 47. If so; desiredgthe lower ends -offtheend 'walls 55 maybe gradually thickened'asat 56 'so-aste form largebearing ened ends 56 of the walls 55 form stops for engaging the thimble and prevent further movement of the stove and its cradle in relation to the upper section. A nipple 57 is provided on the upper end of the section 47 and is adapted to receive the smoke pipe or stack 45. The nipple 57 can be slidably mounted in the smoke stack or the stack itself can be slidably mounted in a thimble carried by the upper deck of the vessel. The side plates 54 of the upper section 46 and the side plates 48 of the lower section 46 are pivotally connected together by means of a pivot bolt or the like 58, and this pivot bolt is in direct alignment with the pivot bolts 40 and 42 which permit the free movement of the cradle and the joint in relation to each other.

From the foregoing description, it can be seen that a novel form of ship stove has been provided, which will permit the stove to assume an upright position at all times, irrespective of the rolling of the ship and thereby permit the easy cooking on the stove.

Changes in details may be made without departing from the spirlt or scope of this invention; but,

I claim:
