14 Claims.

The present invention relates to hydrocarbon fuel burning devices, and more in particular to lamps or lanterns having a fuel combusting burner supplied with hydrocarbon fuel under pressure.

Among the objects of the present invention is to provide a novel lamp or lantern of the type disclosed wherein the various elements of construction are so arranged as to provide a sturdy lamp or lantern structure and which may be manu- 1O factured at a relatively low cost.

The present invention more particularly includes as an object the idea of providing a lamp or lantern wherein the globe or chimney is protected against breakage because of rough handling, which protection is effected by means of a novelly arranged frame support which serves as a mounting for the hood, which in turn serves to support the manifold for mixing the combustible fuel with combustion supporting material, such as air or the like.

Still another object within the purview of the present invention is to provide a novel lamp or lantern wherein the supporting frame embracing the chimney or globe provides a support for the hood and also a connecting medium for a bail. More particularly, the bail may engage with the supporting frame or hood, or both, and is provided with inwardly extending portions serving to prevent displacement of the chimney or globe.

Still another object of the present invention is to provide a novel supporting frame for a hood, in combination with means cooperating with the hood for preventing displacement of the hood in respect to the frame, such means permitting the ready and easy assembly of the hood into and out of its operative position with respect to the supporting frame.

The present invention also contemplates the idea of supporting the manifold by the hood and free from the fuel generator which supplies vaporized hydrocarbon fuel thereto. More particularly, the present invention discloses the idea of sup porting the manifold by the hood, which in turn is supported by a supporting frame and the fuel generator being normally spaced from but projecting into the manifold for supplying the vaporized fuel.

Still a further object of the present invention is to provide a manifold for a lamp or lantern of the type herein disclosed, which is so constructed as to efficiently mix vaporized hydrocarbon fuel with a combustion supporting medium, and which is formed with a mantle support and an air intake conduit, either or both of which may be formed integrally with the main portion of the manifold, or as separate elements.

Other objects, features, capabilities and advantages are comprehended by the invention, as will later appear and as are inherently possessed 5 thereby.

Referring to the drawing:

Figure 1 is a view partly in elevation and partly in cross section of a lantern made in accordance with the present invention; 10

Figure 2 is a fragmentary view in cross section taken in a plane of ninety degrees to the plane of Figure 1, disclosing the lantern thereof;

Figure 3 is a fragmentary view in cross section taken in the plane represented by line 33 of 15 Figure 2 of the drawing; and

Figure 4 is a detached view in elevation of a part of the lamp frame showing the construction thereof more in detail.

Referring now more in detail to the drawing, an 20 embodiment selected to illustrate the present invention is shown as comprising a lantern provided with a hollow base or receptacle 2 for retaining a quantity of hydrocarbon fuel 4, such as gasoline or the like, which may be introduced into the 25 receptacle through an opening normally closed by a screw threaded cap or plug 6 which forms a fluid tight joint with the receptacle. Mounted in the receptacle 2 is a pump 8 provided with a plunger l0 and a discharge tube or conduit i2 30 which terminates within the air chamber M of the receptacle 2 above the level of the fuel 4, this pump being provided, as is well known, for compressing the air within the chamber I4 to force the hydrocarbon fuel through the intake l6 of a fuel vaporizing mechanism, generally referred to as 18, which may be connected as at 2!] to the top of the receptacle 2 and comprises valve means 22 substantially horizontally disposed from which a generator 24 extends upwardly, this valve and 0 generator mechanism being of the usual construction for vaporizing fuel from the receptacle and controlling the flow thereof. The valve mechanism is provided with an upstanding boss 25 to which is connected a supporting frame, generally 45 referred to as 28, this supporting frame including the perforated base 30 which is secured to the boss by means of the screw 32 threaded in the boss 26 .and which draws the base into rigid engagement with the boss, the base being further supported outwardly of the connection to the boss by means of a perforated substantially cylindrical member 34 disposed between the base and the top of the receptacle 2, this member 34 being provided with suitable openings for the valve mechanism 22.

The supporting frame further includes a plurality of upwardly extending supports, such as 36 and 38, which, as disclosed in the embodiment selected to illustrate the present invention, are oppositely disposed and connected adjacent their lower ends to the base as by means of rivets or the like 40. As shown in the drawing, the upright supports are disposed exteriorly of a chimney or globe 42 which is supported on the base 30 and retained adjacent its lower end against lateral displacement by the upstanding flange 44 of the base. These upright supports are connected adjacent their upper ends by a substantially circular band 46 which embraces the upper end of the globe or chimney 42. The upper ends of the upright supports extend upwardly through oppositely disposed openings 48 and 56 of a hood 52 supported upon the frame 28 at the band member 46, each of these upper ends being formed to provide an upwardly extending ear 56 provided with the enlarged aperture 51. The apertures in the ears 56 are aligned with suitable apertures or openings 58 formed in the upstanding wall 60 of the hood 52, these aligned apertures being adapted to receive the inwardly extending portions 62 and 64 of a bail 66 which is used for transporting the lamp or lantern from place to place and to support the same when it is desired to suspend the lantern from a support or the like. These inwardly extending portions 62 and 64 are provided with the bumps or protuberances which are adapted to pass through slots 63 communicating with the apertures 51 of the ears whereby said portions 62 and 64 are received within the aligned openings of the ears and hood in one position of the handle, the handle being locked in position by the protuberances 68 when assembled therewith as shown in the drawing. Furthermore, as clearly evidenced in the drawing, these portions 62 and 64 extend over the upper edge of the chimney or globe 42, which fits within the wall 60 of the hood, to limit upward displacement thereof in the supporting frame 28.

As disclosed in the drawing, the hood 52 normally is supported by the frame 28 at the band 46 and is held against upward displacement by means of the portions 62 and 64 of the bail. The

hood 52 may be inserted in supporting relation with the support 28 by bringing the openings 48 and 50 into register with the apertured ears 56 and moving the same downwardly thereover onto the band 46. The hood is then locked in position by the bail 66 as indicated.

Although the supporting members 36 and 38 are shown as being formed with the ears 56 for holding the hood in position, it is to be understood that any suitable means could be provided in lieu thereof for effecting the same results. It is also to be noted that although in the present disclosure the bail portions 62'and 64 engage with both the ears and the hood 52, nevertheless, if desired, this bail, hood and supporting means 36 and 38 may be so formed and arranged that the bail portions 62 and 64 may engage the hood or the ears only.

The hood is provided with an apertured wall member ID upon which is disposed a top member I2 serving as a support for a manifold I4. This manifold I4 is secured to the hood by means of a screw threaded member I6 connected to the top of the same and which is adapted to extend upwardly through a non-circular opening I8 provided in the member I2. Threaded on the memthe opening I8 and engages member I2 to prevent relative movement between the manifold and the member I2 when the manifold is locked in supporting relation with respect thereto. This locking of the manifold to the member I2 is effected by means of a nut 82 provided with an eyed portion 84 which may be threaded onto the end of member I6. A metal washer 86 and a washer 88, preferably of fire resisting material, are disposed between the nut 82 and the member I2 to permit drawing of the manifold I4 upwardly into engagement with the member I2 upon rotation of nut 82.

The manifold I4 is provided with a passageway 90 adapted to communicate with an intake conend extending through an opening 94 provided in the base 32. This passageway 90 also communicates with the opening 96 which loosely receives the upper end of the generator 24, which generator is provided with the jet 98 adapted to discharge vaporized hydrocarbon fuel into passageway 9!) where it is initially mixed with air passing up through the intake conduit 92 for supporting combustion. This mixture of vaporized hydrocarbon fuel and air passes through the passageway 99 into a mixing chamber I00, where the same is intimately mixed. This mixing chamber I60 communicates through passageway I02 which is formed at its lowermost end with a mantle support I04 upon which is secured a mantle of the usual construction adapted to receive and burn the vaporized fuel for lighting purposes.

From the above description it will be seen that the manifold, together with the air intake conduit 92, is directly supported by the hood and is entirely free with respect to the supporting relation of the generator 24. This manifold is accordingly supported by the frame 28 through the hood 52 and not by the generator. Although the mantle support I04 is shown as formed integral with the main portion of the manifold, nevertheless if desired the same can be formed as a separate unit and secured in any desired manner to the manifold. Furthermore, although the air intake conduit 92 is disclosed as being formed as a separate member threaded to the manifold, nevertheless the construction of the manifold is such that this conduit can be formed as an integral part of the manifold.

In order to move the hood in respect to the support 28 as above described, it is necessary to remove the nut 82 and washers '86 and 88. This permits the hood to be removed over the upper end of .the screw threaded member I6, and atthis time the manifold will be held by engagement thereof with the generator .24 and the engagement of the conduit 92 with the base or valve mechanism I8. Upon moving the hood again into position over the screw threaded member I6, the manifold is moved into a position to be supported by the hood upon rotation of the nut 82 into tightened position.

The present invention also comprehends novel structure incorporated in the lamp as shown in the drawing whereby fuels such as kerosene and the like may be initially volatilized for mixing with a combustible material when the lamp or lantern is first lighted. Such structure comprises a priming cup III) having a centrally disposed opening I I2 arranged to slide over the generator 24. This priming-cup 'I I0 may be secured to the intake conduit 92 in any desired manner, as by welding or a screw connection, and as shown in the drawing, the cup H0 has the upwardly extending bracket :I'M secured as by means of screw I IE to the intake conduit 92. This priming cup is adapted to receive and hold hydrocarbon fuel which may be introduced into the same through an opening H8 formed in the chimney 42. As is Well understood, when the priming fuel in the cup is ignited and lighted the heat generated thereby volatilizes the fuel and air under pressure in the generator 24 whereby the mixture thereof is in proper condition for introduction into the manifold. It is to be noted that the priming cup 6 Hi which is secured to the intake conduit 92 serves as a guide therefor when the manifold is being inserted into place.

While I have herein described and upon the drawing shown an illustrative embodiment of the invention, it is to be understood that the invention is not limited thereto but may comprehend other constructions, arrangements of parts, details and features Without departing from the spirit of the invention.
