SHEET 3 OF 4 20 T r 3/ D 5/ ATTO R N EY ATTACHMENT FOR A GAS REFILL BACKGROUND OF THE INVENTION There are many devices on the market which can be refueled with a liquefied fuel gas such as butane. These devices have appeared in the form of gas cigarette lighters and portable stoves, for example, which have a fuel reservoir therein. The fuel reservoir, when empty, can be replenished by refueling it through an inlet valve in the reservoir. A gas refill supplies the gas through the inlet valve into the reservoir of the lighter.

It has been found desirable and economical to use the refill itself as a fuel reservoir thereby eliminating the need for a selfcontained reservoir and an inlet valve.

SUMMARY OF THE INVENTION An attachment, which has been made to releasably fit upon a refill container, has a needle therein for piercing a rubber diaphragm on a refill. When the diaphragm is pierced, gas can flow through the hollow needle. It is not necessary to use a needle as a means to actuate a refill. If a refill is used having a spring-biased valve thereon, then a plate which fits over the spring-biased valve having an opening therein can be used to actuate the refill and initiate a flow of gas. The gas can then flow into a burner valve from whence it exits and is ignited. The burner valve consists of a housing having a stem therein which is spring-biased to a closed position.

Upon rotation of an adjusting wheel, the stem of the burner valve is lifted to permit gas to flow to the atmosphere and be ignited. By turning the adjusting wheel which is in splined engagement with the burner valve, the amount of gas released from the burner valve can be adjusted and thus the size of the flame produced can be adjusted to suit ones needs.

Accordingly, it is an object of the present invention to provide an attachment for a refill to convert the refill into a controlled flame emitting device.

It is a further object of the invention to provide a flame emitting device which is simple to fabricate and inexpensive to manufacture.

It is another object of this invention to provide a mechanism for controlling the flow of gas through a burner valve.

Further objects and advantages of the present invention will become apparent as the following description proceeds and the features of novelty which characterize the invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

DESCRIPTION OF THE PREFERRED EMBODIMENT In FIG. I there is shown a flame adjusting attachment I0 releasably attached to a refill II. The refill can be of the type which is well known and is depicted in U.S. Pat. No. 3,224,626 filed Dec. 27, 1963 and issued on Dec. 21, I965 to Conrad Zellweger. The refill II has a hollow neck 12 thereon terminating a pierceable, self-sealing diaphragm 13. A fuel, preferably of the liquefied petroleum type, such as butane, is stored under pressure in the refill 11. The refill 11 has a circular rim 14 on the upper portion thereof and a recessed portion 15 therein. The rim l4 and the recessed portion 15 thus define a shoulder I6 therebetween.

The attachment I0 comprises a valve housing 17 which can be a molded plastic part or can be formed of metal or any other material The valve housing I7 has a socket 18 therein into which a valve 20 can be threaded or pressed. Directly beneath the socket I8 is a needle I9 which is hollow throughout its length. The needle can be held in position in the valve housing 17 by a press fit or it can be glued in position or held in place by any known securing means. The gasket 21 prevents liquid gas from leaking back past the needle.

The needle 19 communicates with an open socket 22 in the valve housing I7. The needle 19 is merely the preferable embodiment. The needle can be replaced by a plate (not shown) having an opening therein for the passage of gas. The plate would operate to actuate the nozzle 12, which could be of the aerosol type, i.e. it is spring-biased to closed position of the refill to permit the flow of gas to the burner valve 20.

The valve housing 17 has upper lands 23 which can be any number thereon which forms a cam surface. The cam surface has a gradual inclination from a low to a high point being in the form of a crown cam. The angle of the incline being a matter of choice, however, the rise of the cam must be sufficient to raise a valve opening member high enough to open the burner valve 20.

Integral with the valve housing 17 is a spaced circumferential depending shroud 24 having a circular flange 25 integrally affixed thereto. The flange 25 functions as a gripping surface whereby the attachment 10 can be conveniently removed from the refill l1 and a convenient element to rotate to open and close the valve 20. In this regard a striated or knurled gripping surface can be placed on the end of the flange.

A circumferential bead 26 on the depending shroud 24 serves to maintain a flame adjusting member 27 attached to the shroud 24. The flame adjusting member 27 is preferably formed of a resilient material such as plastic such that by expanding its lower portion outwardly, it can be snapped over the bead 26. When the adjusting member resumes its initial configuration, the bead 26 will prevent its removal from the shroud 24 except by forcing the adjusting member 27 away from the bead 26. The upper portion of the adjusting member 27 is formed with a plurality of recesses 28 therein although any number can be chosen. A top wall 29 having an opening 30 therein serves as a connecting member to adjust the burner valve 20. The burner valve can be a known valve such as shown and described in US. Pat. No. 2,571,435 filed June 1 I, 1949 and issued on Oct. 16, I951 to Alexander L. Flamm. Basically the burner valve has a stem 31 which is reciprocally mounted in a bushing 32, and a longitudinal tube 33 having a bore therethrough. The bushing 32 has splines 34 thereon which interengage with corresponding splines milled or otherwise formed into the opening 30 of the top wall 29. A spring 36 can be used to maintain the valve stem 31 in closed position whereby no gas can flow through the orifice 37, because a seal 38 bears firmly on the orifice. When the bushing 32 is rotated clockwise it moves inwardly by means of its threaded engagement with the fixed socket 39. The bushing bears on the freely movable longitudinal tube 33 which is then forced against the capillary wick 40. The wick functions to bring liquefied gas to the burner valve where it evaporates. By compressing the capillary wick 40 against the fixed sphere 41, the flow of fuel can be regulated as more fully described in U.S. Pat. No. 2,836,044 filed on July 26, I956 and issued on May 27, 1958 to Conrad Zellweger.

A valve lifter 43 which can be a ceramic, a metal or other material fits into the recesses 28 and an opening 44 therein surrounds the bushing 32. A leg or a plurality of legs 45 depend from the valve lifter 43 and functions as a cam follower. The legs 45 extend through the opening 28 in the top wall 29 and rest on the lands 23.

A plate 46 having an opening therein is removable secured to the stem 31 of the burner valve 20. The plate serves to maintain the valve lifter 43 loosely held on the attachment l and when the cam 43 moves upwardly, it bears against the plate 46 which, since it is attached to the stem 30, will be lifted also.

Integral with the lower portion of the shroud 24 is a depending circumferential skirt 47. The skirt is formed of a plurality of fingers 48. A circumferential rib 49 extends around the periphery of the fingers 48. The fingers are separated by slots 50. The fingers are preferably resilient and when they are forced from their rest position, they will return to rest position upon release of the force.

A ceramic cap 51 which can have cooling fins 52 thereon and an opening 53 therein is screwed or otherwise secured to member 27 to retain the valve lifter in place.

An abutment 54 on the shroud 24 bears against a rib 55 on the inner surface of the flame adjusting member 27. The reason for this is that it conveys to the user a tactile feeding that the device has clicked to an off" position.

Thus, when the protruding pointer 56 is adjacent the indicia O, the abutment 55 on the member 27 will have gone past the abutment 54 on the left side thereof as viewed in FIG. 2, and the gas flow will be shut off. When the pointer 55 is moved to the indicia L, the abutment on the member 27 will pass the abutment 54 and the user will feel a slight restraint and the valve will open slightly such that a low flame will be produced when the gas is ignited. As the member 27 is rotated in a counterclockwise direction the valve will open to a greater extent thereby permitting more gas to flow until the pointer reaches the indicia M. At this point the rib 56 abuts the high stop 57 and the maximum flame height is reached. A similar low stop 58 is circumferentially spaced from the high stop and functions to prevent rotation past the closed indicia O.

The embodiment shown in FIGS. 9-12 comprises a valve housing 17 having a socket 18 therein into which a burner valve 20 is threaded or pressed. There is a needle 19 which functions as in the previous embodiment.

The modification differs from the previous embodiment basically in the type of valve lifter which is employed. The valve lifter 43a shown in FIG. is formed from a metal stamping although any known material and any known method can be employed to fabricate the lifter. The valve lifter 43a comprises a plurality of legs 45a having a tab 51 integral with and located at the terminal portion of each leg 43a. Each tab 51 has upturned ears 52 which form each leg into a cam follower which rides on the tapered lands 23. In all other respects the valve lifter in the embodiment of FIGS. 9-12 functions like the valve lifter 43 previously described.

In actual operation, the attachment 10 is placed on the refill 11 by pressing the fingers 48 into the recess on the refill. Because the fingers are resilient, they will be cammed inwardly of the shoulder 16 and then become locked in the recess 15 below the shoulder 16. The needle 19 or other refill actuating means will then pierce or otherwise actuate the nozzle of the refill. The gas in the refill travels up the hollow bore of the needle 19 and into the capillary wick 40. Since the stem 31 having a seal 38 on the end thereof is spring-biased into closed position, no gas can pass through the orifice 37.

In order to initiate a flow of gas, the user must rotate the adjusting member 27, which can have a roughened surface, in a counterclockwise direction with respect to the flange 25. Conversely, the flange 25 can be rotated with respect to the adjusting member 27. As the member 27 is rotated, the rib 56 moves over the abutment 54 and the valve lifter is raised by the inclined lands 23. The depending legs 45 of the cam lifterfollow the rising cam surface and is thereby lifted upwardly away from the refill until it abuts-the plate 46. Since the plate 46 is secured to the stem 31, the stern and seal 38 move upwardly to permit gas to flow through the bore in the stem to the atmosphere. The issuing gas can then be ignited. The size of the flame can be adjusted by rotating the adjusting member 27 within a predetermined limit between indicia L and M so as not to shut off the flow of gas. Rotation of the member 27 causes rotation of the bushing 32 to which it is splined. The bushing threads its way into the socket 39 and forces the lon' gitudinal tube 33 to compress the capillary wick 40. Since the flow of gas is thereby limited or is made more plentiful, depending upon the pressure exerted on the wick, the flame height will be lowered or raised to suit the needs of the user. To shut offthe flow of gas the adjusting member is rotated in a clockwise direction and when the rib 56 goes over the abutment 54, the user can feel that the unit has been shut off.

While there has been shown and described a single embodiment of the invention, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention, and that it is intended by the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.
