Application filed September 13, 1915. Serial No. 50,511.

To all whom it may concern:

Be it known that I, ARNOLD 0. Item, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Igniter- Torches for Gas-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention refers to igniter torches for gas stoves and it has for its object to provide a simple, economical and efiective hood for such torches, which hood in this instance forms part of the stove grid. Heretofore the hood portion of the torch-head has been attached in some manner to said head and constitutes with the head a unitary device to be sold to the trade. This construction not only adds materially to the cost in manufacture but under the usual conditions a torch of the ordinary type, in its installation, requires more or less adjustment. This is effected by bending or deflecting by hit or miss methods the delicate tube portion of the torch-head so as to properly aline the firing ports of said head with the burners. Consequently an unsatisfactory operating device will frequently result. With my present improved form of torch head, the shield or hood portion is a separate element and part of the stove grid, and when the head portion of the torch is approximately correctly positioned with relation to the series of burners thereabout, the grid carrying the shield or hood is dropped into place and will engage a portion of the torch-head and press the same slightly downward so as to aline its ports upon a correct horizontal plane, whereby they will discharge upon the several burners. Thus the firing head is to a certain extent self-centering or self posi-' tioned when the grid is dropped into position over the burners.

A further advantage resulting from my improved arrangement wherein the grid carries the shield or hood is that the weight of the hood is eliminated from the more or less delicate :supply tube which carries the flash igniter.

In illustrating one example of my improved construction of torch-head attention is called to the fact that, I do not limit myself to any specific design of shield inconnection with the grid as there are obviously many forms within the knowledge of the skilled mechanic for carrying out the invention, whereby the function of the hood is assumed by the grid. It should further be understood that in attaching the shield to the grid under ordinary conditions, it would be cast as an integral part thereof, whereby there is comparatively no increase in the expense of manufacturing-the grid and in lts arrangement in connection with the grid it is only necessary to provide clearance space or firing ports of some type in con nection with the wall of the shield, whereby the jet flames will not be interrupted.

With the above objects in view the inven tion consists in certain peculiarities of construction and combination of parts as set claimed.

In the drawings Figure 1 represents a plan view of a stove grid made in two sections and embodying a shield conforming to my invention, a portion of one of the grid sections being broken away to more clearly illustrate said shield; F ig. 2, an enlarged sectional view.of a portion of the grid and shield, the section being indicated by line 2-2 of Fig. 1, and in this view a fragment of the torch-head is shown centered with relation to the shield; Figs. 3 and 4 illustrate similar sectional views of other forms of shield exemplifying my invention with the torch-heads in place.

Referring by .characters to the drawings, 1, 1, represent the ordinary grid plates which are fitted over the burners of a gas stove, not shown, the burners being arranged to center at the scrolled openings at, four of which are shown. The rid sections are provided with transverse bars 2, 3, which, as

shown, are match-jointed at the center of the stove, the bar 2 being provided with a lip portion2', upon which the bar 3 rests. The construction of these bars, however, forms no part of my invention as they may be supported in various ways and as a matter of fact in some instances the grid is made in one piece. When, however, as shown in Figs. 1 and 2, the grid is made in sections, the central portions of the bars 2 and 3 are each cast with one-half 4- of a torch-head shield A."

As shown in Fig. 2, the two-part shield member is formed in cup shape in connection with the bars 2 and 3 and extends downwardly and the lower edges of the walls are formed-with firing apertures or ports 5. The shield so formed is adapted to receive any type of burner head B, which burner head is provided with the usual lateral jetapertures 11 and-is supported by and supplied with gas from the tube 1). The'shield extends below the jet apertures in the usual manner, as shown in Fig. 2 of the drawings, the burner-head is also provided with a spider. having an upturned outer edge which is adapted to engage the lower edge of the shield and thus center. the torch-head B with relation thereto. Hence in assembling the device, the toreh-hbad -B is arranged to extend slightly above its ordinary firing plane and when the'grid members are dropped into place the lower edge of the shield A will enter the flange of the disk 0 and thus "said burner will be properly centered and discharged through, the firing apertures 5 pressed downward to the desired horizontal' plane, whereby its jet flames will be to the series of gas burners, not shown. By utilizing the disk 0, as shown, it will be I observed that the torch-head shield will thus be to a certain extent closed, whereby cross-currents of air will be prevented from snuiflng out the pilot-light which is kept constantly burning at the tip of the torchhead. i

. 'Fig. 3 of the drawings illustrates a form of shield or hood A. 'wherein the firing ports 5 are circular in form and the depending walls of the shield extend below the same a predetermined distance. In this exemplification of my invention the torchhead B is shown provided with an upwardly extended nib e, which centers in a central recess 6 that is formed in the upper I portion of the shield. Thus when the grid v Lwith i. g W

operation by suitable valve mechanism, not

- shown.

e is dropped into place the recess e coming in register with the ,nib e will properly aline the assoeiatedparts of the torch-head with relation to the stove burners. In the form of torch-head B shown in Fig. 3 the pi1ot-light C is illustrated as being supplied as by a separate tube, while in the first torm mentioned the tube 7) supplies both the plilot-light and the jet flames with supply is increased in a firing Attention is also directed to the fact that in Fig. 3 of the drawings the grid is shown as a single piece and theshield is thus not interrupted centrally or is not halved.

Fig. 4 of the drawings shows still another form of my invention wherein the shield sections 4, 4, are stopped above the firing line of the jet flames and inorder to protect said jet flames from cross-currents of air an apron 4 is formed below the lower edge at the shield members and this apron to its association with the theproper operation of the torch-head. It

also follows that in all instances the shield or dome in addition to performing the functions mentioned, serves as a protector for the constantly burning pilot-light of the torch-head against liquids or drippings that might overflow from cooking utensils.

In each of the exemplifications shown the I shields arecircular in foru'lbut'it is manifest that the grid ribs or bars can be formed with web extensions below the ordinary plane of the grid to produce the desired shield effect and these webs, which will extend down to form the shield, may be po-- lygonal in form or in any other suitable design depending upon the taste of the manufacturer or designer, the essential feature of the invention being the provision whereby some form of hood or shield is associated with the grid in contradistinetion torch-head. I claim: j 1. A flash igniter comprising the combination with a gas stove having a series-of burners and a supporting grid above the burners of an igniter tube having a vertically disposed torch head provided with lateral jet apertures and a shield member carried by and depending from the grid and receiving the torch head, with the lower portion of said shield member disposed below I the plane of the jet apertures.

cally disposed torch headprovided with lat:

eral jet apertures, and a depending shield member formed integrally with the grid and receiving the torch head with the lower portion of said shield member disposed below the plane of the jet apertures.

3. A flash igniter comprising the-combination with a gas stove having a series of burners and a supporting grid above the burners of an igniter tube having a vertically disposed torch head provided with jet apertures, a shield member carried by and depending from the grid, with the lower portion of said shield member disposed below the plane of the jet apertures, and means associated with the shield and torch head for holding the torch head centered within the shield.

fl A flash igniter comprising the comb nation with a gas stove having a series of burners and av supporting grid above the burners of an igniter tube having a vertically disposed torch head, a shield member adapted to receive the torch head, and carried by and depending from the grid, an 'apertured plate. adjustably carried by the bination with a gas stove having a series of burners and a'supporting grid above the burners of an igniter tube havin a vertically disposed torch head, provided with horizontal firing ports and a shield member for the torch head comprising a pair of vertically alined frusto-conical Wall portions, a closure at the top of the upper wall portion, arms connecting thewall portions, and the firing ports of the torch head being disposed between the planes of the adjacent ends of the wall portions.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of 5 Wisconsin, in the presence of a witness.
