GAS SAVER.

Application f led January 10, 1927. Serial No. 160,108.

This invention relates to improvements in gas-burner attaclunents of that type used in connection with burners of cooking stoves of the platform or hot-plate class :1 wherein the burner is positioned on a plane below the grating upon which the cooking utensil is disposed, and the vents in the burner are located so that the flames are di rested upwardly.

Although devices have heretofore been developed to conserve the heat produced by such a burner by shielding the flames from air currents and preventing them from being deflected from their directly upward flow, I am not aware that any prior inventions have been wholly ei fective or practicable.

The object of my invention is to provide an attachment for gas burners of the kind referred to, which is capable of adaptation to burners of different makes and diameters, and which is easy to install, dependable, ef-

cient and durable, and which is economi al of manufacture.

The advantages sought by my invention are accomplished by, and the. invention is embodied in the new construction, combination and arrangement of parts illustrated in the accompanying drawings, and described in the following specification. The invention is defined in the appended claim.

The several parts of my invention are identified by suitable reference characters, applied to them in the drawings, in which- .liigure 1 is a perspective v1ew of my 1mproved gas burner attachment.

Figure 2 is a perspective View showing the relative positions of the ends of the band before the jointureclip has been placed in position.

Figure 3 is a detail perspective view of the jointure clip showing the position of its grip fingers before placed at its position in connection with the ends of the band.

Figure t is a plan view of my improved attachment in position for use on a burner of common form.

Figure 5 is a side view taken in direction of the arrow 5 in Figure l.

My ention contemplates the providing of a metal bar of suitable length curled into the formation of an annular band, and a metal jointure clip adapted to hold the meeting ends of the bar in alignment, one end the bar being secured to, and the other as end. of the bar being movable in, the said all jointure clip; the device thus constructed beingcapable of expansion to encircle'the burner and by itsconstrictory action, to then automatically retainv tight connection with said burner, regardless of contraction and'expansion of the burner, and also of the band itself, due to temperature changes.

To provide for alignment of the band on a burner in which the top surface of the inlet pipe is on a plane abnormally above the plane of the bottom of the burner, an inclined recess is provided in the lower portion of the band. i My invention in the present specification is embodied in an attachment of dimension and form suitable for burners of average size, the band consisting'of a steel or iron bar it about one and one quarter inches wide,

three sixteenthsof an inch thick and of length to constitute a bandiaboutifoui'f'and one half inches in diameter. This bar is of predetermined length, sheared from stock material and at the time of shearing is indented near one of its ends, namely its end A with shallow transverse groove A and the edge A is slightly tapered. A relatively long recess in the lower edge of the body portion of the bar has an inclined face A and is preferably formed by shearing. This operation may be performed by dies or ranged in the power press to act concurrently with the die that shears the end of the bar and that also forms the indentation A The bar is then curled or rolled into annular form, its curvature being such that one of its ends passes or overlaps the other a slight distance, as shown in Figure 2.

The jointure clip is made of sheet steel and is of the formation as shown in Figure 3. Complement-a1 grip fingers B and B spaced apart, a distance equal to the Width of the end portion A of the bar are each bent at a right angle to the body portion B of the clip, thence at an angle inclined toward the said body. Each of these grip fingers is provided with an indentation at its edge which provides the ridge B When this jointure clip is started on to the tapered edge A of the end A of the band, and is then slipped longitudinally, the inner faces of the fingers B bind tightly against the surface of the band and the ridges B snap into the grooves A of'said band. Thus. the jointure clip is tightly secured to the end A of the band. The band is then slightly expanded. the end A snapping into registration with the end A The complen'iental retainer fingers B and Bare then bent at a right angle to the body portion of the clip, thence parallel thereto, (see dottedv lines in Figureti) and in position engaging the edges and inner face of the end A? of the hand (as shown in Figure 1).

It obvious that aband device constructed in accordance with my invention is not only of rugged strength and bull: to withstand the wear and tear incidental to its eontimial use, but it is 'apable of being easily expanded or distended by the user, so that it may be placed at position encircling the burner; \Vhen so placed in position its tendency to return or constrict to its normal diametercauses it to grip the edges of the burner effectively, thereby maintaining its position. One end of the bar being free in its connection with the jointure clip, there is a sufficient yield to compensate for such change in diameter of the burner as may occur due to rising and lowering temperatures.

To accommodate a burner of the make in which the inlet pipe is at a height abnormally above the plane of the bottom of the burner, there is provided the inclined recess. Thus, the user may set, or position the band to rest directly on said inlet pipe at such height as may be desired.

I am a are that minor changes may be made in the detail and general construction of my invention within the scope of same as defined by the appended claim, without departing from the spirit of my invention or sacrificing any of its advantages.

What I claim as my invention, and desire to secure by Letters Patent, is

A gas burner attachment consisting of a resilient divided baiuh one of the ends of the band having its inner edge of beveled formation, and its inner :l'aee being provided with a groove, a sheet metal jointure plate having two pairs of opposed complemental lingers, the lingers of one pair being bent toward each other and to proximate positions near the body portion of the plate and having ridges therein so that when the beveled end of the band is passed underneath these fingers, their ridges become imbedded in said groove, and the other pair of fingers being bent toward each other and to engagement with the inner face of the other end of" the band after the latter has been disposed in engagement with the body portion of the jointure plate.
