UNITED STATES CHRISTIAN J. BERGLANN, OF SEATTLE, WASHINGTON.

STOVE.

Specification of Letters Patent.

Patented Mar. 15, 1921.

Application filed April 19, 1920. Serial No. 375,166.

To all whom it may concern:

Be it known that I, CHRISTIAN J. BERG- LANN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a certain new and useful Improvement in Stoves, of which the following is a specification.

My invention relates to improvements in stoves that are adapted for use on ship board or in places where they are subjected to a tilting motion and the object of my invention is to provide a stove that is su.p ported by a universal joint within a frame in such manner that the top of the stove will always remain in, a horizontal position regardless of the angle at which the frame is moved.

A further object is to provide a novel frame structure and a novel arrangement of a ball and socket joint that is particularly adapted for supporting an oil stove.

A still further object is to provide simple and efficient means for grasping and holding a cooking 'utensil that may be placed upon the stove. I

A still further object is to provide novel means for preventing any dirt from lodging within the ball and socket joint of the stove. A still further object is to provide a novel means for preventing the flame of the stove from being extinguished when the stove is used in an open boat.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel con; struction, adaptation and combination of parts, as will be more clearly hereinafter described and claimed.

I accomplish these objects by devices illustrated in the accompanying drawings, wherein Figure 1 is a view in side elevation of a stove constructed in accordance with my invention.

Fig. 2 is a view in vertical section of the same substantially on a broken line 2, 2 of Fig. 1.

Fig. 3 is'a plan view of the same, the bottom pan being omitted.

Fig. 4. is a view partly in plan and partly in section substantially on a broken line 4, 4 of Fig. 2.

Fig. 10 is a fragmentary sectional view illustrating a detail of the stove support shown in Fig. 9.

Fig. 11 is a fragmentary view in elevation of a portion of the mounting and universal joint mechanism shown in Fig. 9.

Fig. 12 is a plan view substantially on a broken line 12, 12 of Fig. 9 parts being shown in cross section.

Fig. 13 is a sectional view of a stove using electrical heating means.

Fig. 14 is a plan view of the device shown in Fig. 13.

Fig. 15 is a detail in perspective showing a fragment of a plate used in the electrical stove.

Fig. 16 is a sectional view on broken line 16, 16 of Fig. 13 showing parts in plan.

Like reference numerals designate like parts throughout the several views.

Referring to Figs. 1 to 8 inclusive the numeral 1 designates a pan that also serves as a stove base andis provided on one side with an integral lug 2 into which the bottom end of an upright tubular support 3 is tightly screwed. The upright support 3 is bent at right angles to form a horizontal arm 4 that terminates in an upturned end 5 which is preferably located substantially above the center of the pan 1.

The upturned end 5 is rigidly secured to a relatively large sphere or ball 6 that fits within a socket in a two part yoke or mounting 7, small bearing balls 8 being provided 1gviltlhin the socket and adapted to roll on the Suspended from the yoke 7 by two pipes 9 and 10 is a combined fuel bowl and weight 11 that always tends to hang in a vertical position regardless of the angle into which the pan 1 and upright support is turned.

The fuel bowl 11 has receptacle 12 for fuel and the pipes 9 and 10 are preferably screwed through the top wall of the receptacle 12 and are connected with smaller pipes 13 and 14 that project downwardly into the receptacle and terminate near the bottom thereof so that fuel may be forced upwardly therethrough.

The fuel receptacle 12 is provided with aninlet opening 15 through which fuel may be 7 adapted to be engaged beneath a cleat 23 on the side of the bowlv to hold the piston stem 20 in its innermost position when the pump is not in use.

19 is a safety valve that serves to relieve excess pressure of air within the oil reservoir 12. p I

The upper ends of the pipes-9 and. 10 communicate with a passageway or chamber 24 in the upper portion of the yoke 7 which passageway in turn communicates with an oil burner 25 that may be of any desired well known form.

Supported above the yoke 7 bythree equldistantly spaced brackets 26 is a normally horizontal plate 27 having a centrally arranged opening 28 and provided with radial ribs 29 on which a cooking utensil 30 may rest. The top plane of the plate 27 is far enough above the top end of the burner 25 so that the best results from the flame of such burner will be obtained. The top side of the plate27 is preferably slightly convex as shown in Fig. 2 so that liquids that may be spilled onto such plate will quickly drain off and be caught by the pan 1.

The ribs 29 support the cooking utensils far enough above the surface of the plane 27 so that flame from the burner may pass outwardly therebetween and come in contact with practically the entire bottom of the cooking utensils.

The burner 25 is disposed within a housing 31 that is secured to the plate 27. The bottom of the housing 31 is provided with a plurality of perforations 32 and one side of such housing is provided with an opening 33 that is arranged to be opened and closed by a door 34 that is 'slidable in guides 35.

The housing of the burner 25 and the provision of the door '34 makes it possible to use this stove in the open in windy weather without danger of having the fire extinguished by the wind. When the stove is used in the wind the door 34 may be partially or entirely closed. At all other times the opening of the door 34 may be regulated to secure the draft that is best for the flame of the burner.

As a means for retaining or holding a cooking utensil on the top of the plate 27 I provide-two arcuate arms 36 and 37 that are each free at one end and are rigidly connected at the opposite end with pivots 38' relation to the arm 37 and is provided on its end with a downturned portion 44 that projects through a slot 45 in the lever arm42.

l The lever arm 42 is fulcrumed on a fixed pivot 46 on the plate 27 and is provided with a pawl '47 thatis arranged to engage with teeth 48 on the edge of the plate 27 to lock the lever 42 in a fixed position. 7

When the lever arm 42 is moved in a contra-clockwise direction from the position shown in Fig. 3, the arms 36 and 37 will be moved away from each other so that a cooking utensil may be placed on the plate 27 between such .arms. When the arms 36 and 37 are spread apart and the lever 42 is moved in a clockwise direction as viewed in Fig. 3, such arms will be moved toward each other and may be caused'to engage with and hold a cooking utensil.-

From the above description it will be seen that the entire stove with the exception of the base or panl, the supporting standard composed of the parts 3, 4 and 5, and the ball 6, is free to oscillate on the universal joint formed by the socket in yoke 7 and bearing balls 8 which roll on the large ball 6 and that the relatively heavy bowl 11 will always hold the stove in a vertical position with the plate 27 horizontal regardless of the angular position into which the frame is turned.

The yoke 7 forms a cap or cover for the universal joint and serves to prevent grease and liquids that may escape from the cooking utensils from gaining access to the bearing.

In Figs. 9 to 12 inclusive I have shown a slightly modified form of the invention comprising a pan shaped base 50 thatis centrally provided with a lug 51 into which is screwed a rigid upright supportingpost 52.

Secured to the top end of the. post 52 is a relatively large ball or sphere 53 that fits within la-suitab'le socket= formedin a two part yoke. 54,:ibearing balls 55 being provided within the T socket. and adapted to roll on the large ball153 to thereby form a universal-joint.

Suspended from the yoke "54byimeans of threetubular-supports 56,57 and 58 is a combined fuel receptacle and weight 59 that is preferably of cylindrical shape and of relatively large diameter as shown in the drawings, and that has a relatively large circular opening 60 in its central portion so that the post 52 may swing into various angular positions without interfering with the fuel receptacle 59.

The fuel receptacle 59 is provided with a pump 61, a fuel inlet opening 62, and a safety valve 63 that are all substantially identical with the similar articles described in connection with the bowl 11.

One of the pipes by which the fuel receptacle 59 is suspended, as the pipe 56, serves as a fuel conduit and is connected with a passageway 64 in the yoke 54, which passageway 64 communicates with a burner 65 that is identical with the burner 25 hereinbefore described.

The plate for supporting the cooking utensils, the means for supporting the said plate above yoke 54, and the means for holding the cooking utensils in place on said plate are identical with the corresponding devices described in connection with Figs. 1 to 9 inclusive.

The operation of this stove is substantially the same asthe operation of the stove shown in Figs. 1 to 9, the fuel receptacle 59 serving as a weight to always maintain the stove in a vertical position regardlessof the angle into which the base 50 and upright support 52 are tilted, the amount of relative tilting movement between the stove proper and the supporting mechanism being necessarily limited by the size-of the opening 60 within the bowl 59.

In Figs. 13 to 16 inclusive, I have shown my stove, which may be either the type of stove shown in Figs. 1 to 8 or in the type shown from Figs. 9 to 11, as provided with an electrical heating element that is disposed within a housing 66 which is secured toa plate 67 that is adapted to fit over the central opening 28 in the plate 27 upon which the cooking utensils are placed, the plate 67 being provided on its periphery with integral channel shaped guides 68 that are adapted to fit over the ribs 29 on the top of the plate 27 and the ribs 29 preferably being notched as at 70 so that the plate 67 will be flush with thetop surface of such ribs 29.

If desired either of the types of stove hereinbefore described may be provided with suitable means for locking them to prevent the operation of the universal joint,

which means may be employed when the stoves arein use in places where they are not subject to a rocking motion, or, if d'esired,-,means may be provided for locking the-universal joint in such a manner as to prevent universal movement of, the stove about such joint but still to permit swinging motion of the stove in a single plane.

From the foregoing description taken in connection with the accompanying drawings the advantages of the construction and of the method of operation of my shi stove will be readily apparent to those skllled in the art to which the invention pertains, but while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, it will be understood that the structure shown is merely illustrative and that such changes may be made as are within the scope of the following claims.

What I claim is:

1. A stove of the class described comprising a base, a rigid support projecting upwardly from said base, a ball secured to the upper end of said support, a yoke arranged to fit over said ball and to oscillate thereon said yoke having a fuel passageway therein, pipes connected with said yoke and communicating with said fuel passageway, a combined weight and fuel reservoir secured to the bottom ends of said pipes and communicating therewith, an oil burner secured to said yoke and communicating with the fuel passageway therein, and a plate supported in operative relation with respect to said oil burner.

2. A stove of the class described comprising a base, a rigid support projecting upwardly from said base, a relatively large ball secured to the upper end of said support, a two part yoke having a fuel passageway therein and having asocket adapted to fit over the upper side of said large ball, ball bearings disposed within said socket and arranged to roll on said large ball, downwardly projecting pipes secured to said yoke and communicating with the fuel passageway therein, a combined weight and fuel reservoir secured to the lower ends of said pipes, the said pipes communicating with the interior of said fuel reservoir, an oil burner connected with said yoke and communicating with the fuel passageway therein, and a plate supported from said yoke in operative relation with respect to said oil burner.

3. In a stove of the class described, a burner, a plate supported in operative relation with respect to said burner for receiving cooking utensils, two curved arms each pivoted at one end to said plate for engaging with the sides of a cooking utensil to hold the same, a hand lever fulcrumed on the bottom side of said plate, a catch memher-on said hand lever, teeth on the edge of said plate and arranged to be engaged by said catch member, divergent slots in the 1 inner end of said hand lever, and two aotu ating arms, each rigidly connected at one end with the pivot of one of said eooking utensil engaging: arms and provided at the other end with a downturned portion that is operatively disposed in one of the slotsin 10 the inner'end of said lever arm.
