GAS-LOG.

Specification of Letters Patent.

Patented Feb. 20, 1912.

Application filed July 8, 1911. Serial No. 637,496.

To all whom it may conccm:

Be it known that I, OTTO E. HANSEN, a citizen of the United States of America, and a resident of Perth Amboy, Middlesex County, New Jersey, have invented certain new and useful Improvements in Gas-Legs, of which the following is a specification.

This invention relates to gas logs and has for its object to provide a gas log heater of novel and improved 'Construction and one which may be manufactured at low cost.

Another object of the invention is to construct the gas logs of several parts easily assembled around a cast iron burner so that injured parts may be easily replaced.

Other objects will appear as this specification proceeds.

In the drawings illustrating the invention and accompanying this specification Figure 1 is a front elevation of a gas log embodying my invention. Fig. 2 is a similar view with parts removed and parts in section. Fig. 3 is a transverse sectional view and Fig. 4 is a perspectve view of one end of the iron burner.

I construct my gas logs with a cast iron burner as a base and support upon which I mount the log portions so as to conceal the burner and to obtain the usual artistic efect of burning wood logs.

In the drawing the reference character 5 denotes the iron burner which is provided with numerous narrow slots 6 communicating with the interior gas chamber 7 8 is an inlet pipe preferably cast integral with the burner body and which communicates with the gas chamber at the center thereof at 9. Immediately above the latter I provide a partition 10 having a narrow slot 11. The partition serves as a baffle plate to defiect the flow of the gas so that the latter will pass evenly to all the open ings 6 and the narrow slot 11 permits enough gas to pass straight upward to the center openings 6. The inlet' pipe is provided with an air inlet at 12 and a screw threaded opening 13 for the reception of a gas pipe 14 through which the gas is admitted to the burner and controlled by a valve 15. Thus the gas and air is mixed in the pipe 8 to obtain the proper fuel miXture for ignition at the openings 6.

The burner is Secured at both ends to the two feet or supports 16, 16 by means of bolts 17, 17. On the front side the burner carries two lugs 18, 18.

19 is a gas log, preferably hollow, and which is Secured to the feet 16 by bolts 29 at each end, passing through slots 20. in the said feet. Thus the position of the log may be adjusted to obtain the proper effect.

The front of the log is coated with asbestos 21 or other non-burnable material.

22 is a log in the shape of a shell having recesses 23 by means of which the shell may be hung on the lugs 18, see Fig. 3.

24 is a water receptacle which rests on the feet 16 and the front of which is shaped in imitation of wood the same as the shell 23 and the log 19 and as illustrated in Fg. 1, which figure also illustrates the general arrangement and how the shell 22 is cut out at 25 to admit the gas pipe 14 so that the valve 15 can be operated from the front.

When the valve 15 is opened the gas fioWs through the pipe 1 1 into the inlet pipe 8 and at the same time air is drawn in through the inlet 12. The gas is ignited at the openings 6 and the flames lick up in front of the asbestos 21 and up over the log 19 giving a natural appearance of burning wood logs.

By reason of the Construction as' described it will be seen, that in case one of the logs should crack or otherwise become injured, it can readily be replaced. Another advantage of this Construction is its narrowness as viewed in Fig. 3.

Details in the Construction may of course be varied within the scope of the invention and the claims.

I claim:

1. The combination of a metal burner member having ignition openings at the top, supporting legs bolted to the said member for the support thereof, an upper artificial log member adjustably secured to the said legs and having a forwardlycurved surface overhanging the said ignition openings and provided With a coating of non-burnable material.

2. The combination of a metal burner having a longitudinal inner gas chamber with ignition openings at the top, a fuel inlet formed at the bottom of the said burner, a baffie plate having a narrow slot supported above the said fuel inlet within the said gas chamber and extendng for a slight said ignton openngs and provided With a 10 distance to both sdes of the said nlet, coatng of non-burnable material. means for supplyng a fuel mxture to the Signed at New York, N. Y. this 7 day of said burner, metal legs for supporting the July 1911.

letter, an artificial log member supported on the front of the said burner, a second OTTO HANSEN' artificial log member adjustably bolted to Wtnesses:

the said supporting legs and having a for- IVAN KONIGSBERG,

wardly nclned surface overhangng the K. G. LE ARD.
