GRATE ATTACHMENT.

Application filed April 7, 1919. Serial No. 288,094.

To all whom it may concern:

Be it known that I, RALPH W. ANTHoNY, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Grate Attachment, of which the following is a specification.

This invention relates to improvements in grate attachments, the object of the invention being to provide an improved attachment for supplying gas to the grate for the purpose of starting a coal, wood or other fire without the use of kindling wood, and which attachment may be readily applied to any grate without change in the construction of the grate.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention consists in the novel features of construction and combination of parts which will be more fully described hereinafter and particularly pointed out in the claims.

In the drawings accompanying and forming part of this specification,

Figure 1 is a plan view of a grate bar showing my improved attachment applied theireto, the bar being broken away at its en s;

Fig. 2 is a side view showing the attachment applied to a grate bar, the gas supply pipe being shown in section; and

Fig. 3 is an end view illustrating the device connected to a plurality of grate bars.-

The same characters of reference desig nate the same parts in the different figures of the drawings.

Referring to the drawings, 2 designates a grate bar having the usual projections or lugs 3 extending from the sides thereof, the lugs being slightly curved at their upper sides transversely of the grate bar, as shown in Fig. 2. The grate bar is usually mounted at its ends in bearings in the stove or furnace, its front end projecting through the front wall of the fire box and formed to receive a suitable shaker handle for rocking the grate.

The gas attachment forming the subjectmatter of this invention consists of a pipe 4 provided with a plurality of perforations along opposite sides thereof, said perforations being so located as to lie directly below the spaces between the lugs 3. For leading the gas from the pipe 4 to the proper points where it is to be ignited, I provide a plurality of small tubes 5, each bent into L- shape at its lower end to provide a stem 6 that is secured in one of the perforations in the pipe 4:, so that the upper ends of the tubes located at opposite sides of the pipe 4: may freely straddle the grate bar 2. The upper ends of the tubes 5 extend to almost the level of the upper surface of the lugs 3 and are turned over, as shown at 7 in Fig. 2, so as to prevent ashes or dirt from getting into the tubes. For securing the attachment to the grate, the pipe 4 is provided near each end thereof with a pair of loops 8, one at each side, which loops may be cast integral with the pipe. A strap or collar 9 passes over the grate bar and is provided with a pair of depending legs 10 adapted to pass through the loops on the sides of the pipe 4 and are perforated at their lower ends for the reception of a fastening bolt 11 for holding the attachment in place. The collar 9 is preferably made to fit loosely around the grate bar, so that the rocking of the bar will not appreciably disturb the gas connections. As a precaution, however, against any leakage that might be caused by any slight rocking of the attachment when the grate is rocked, I prefer to provide gas-tight packing joints at the point where the gas pipe 12 connects with the attachment, as shown at 13 in Fig. 2, a pair of elbows 14 being interposed at this point to prevent interference with the shaker handle.

In Fig. 3 the attachment is shown applied to three grate bars, a common supply pipe 15 being connected by means of a threeway connection 16 with all of the attachments. In a similar manner the attachment may be applied to any desired number of grate bars.

While I have described in detail the structure illustrated herein, it is to be understood that I do not thereby limit my invention to the precise features of construction shown, as I am aware that many mechanical changes may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.

Having thus described my invention, what I claim is:

1. A gas supply attachment for grates, comprising a pipe having a plurality of radial perforations along opposite sides thereof, a plurality of tubular members secured in said perforations, said members projecting some distance above said pipe and turned over at their upper ends, and means for securing the pipe to a grate bar.

A gas pp y a achm n or ates, comprising a pipe having a plurality of radial perforations along opposite sides thereof, a plurality of tubular members secured in said perforations, said-members projecting some distance above said pipe and provided With means at their upper ends for preventing access of ashes or dirt toithe interior of said members, and means for securing the pipe to a grate bar.

3. A gas supply attachment for grates, comprising a pipe having a plurality of radial perforations along opposite sides thereof, a plurality of tubular members provided With L-shajoed stems secured in said perforations, saidmembers projecting some distance above said pipe and provided With means at tl eir upperends for preventing access of ashes or dirt to the interior of said members, loops formed on opposite sides of said pipe straps adapted to encircle a grate bar and having legs passing through said loops, and rneans for connecting the ends of said legs below the pipe.

In testimony thatI claim the foregoing as my own, I have hereto afiiXedlnny signature inthe presence of tivo Witnesses.
