IMPROVED GAS-MACHINE.

The Schedule referred to in these Letters Patent and` making pari: of the same *Hwa- To all 'whom/traag cauce/ra:

Be it known that I, HUGH WAIN, of Ravenna, in

the county of Portage, and State of Ohio, have in-v.

vented certain new and useful Improvements in Gas- Machines; and I do hereby declare that the following is arfull and complete description' of the construction and operation of the same, reference being had to the accompanying drawings, making part f this specification, in which- V Figure. l is a side view of the apparatus.

u Figure 2, atop view of the inside.

Figure 3, a vertical section.

Like letters of reference refer to like parts in the diii'erent views.

This invention relates to the production of illuminating-gas by compelling a current of air through any ofthe ycompouigds known as hydrocarbon-oil.

, Ing.2, A representslannuter shell or cylinder, in which is placed an oil-tank, B, on the brackets a, whereby it is elevated above the iioor of the cylinder.

Within said tank is erected a concentric wall, G, thereby making saidv tank of a narrow, circular form, C', and which is elevated above the floor of the sides B G, as shown in fig'. 3. K

The bottom of saidcircular tank is perforated with A holes, b, the purpose of which will hereinafter be shown.

D, fig. l, is a gasometer or receivei,constructed and arranged in the ordinary way, and which is put in connection with the shell or cylinder A by means of the gas-pipe E. Y 2

On the opposite side of the cylinder is a blower, F, and which is put in connection with the cylinder A by means of the air-pipe G, the inner end of which terminates in the space F, immediately under the tank.

` The space H, surrounding the oil-tank B, is iilled with ashes, to serve as a poor conductor of heat, whereby an equilibrium of temperature is obtained to the apparatus and its contents, so 'that' itV shall remain unaffected in its operation by the vicissitudes of the weather.

I` is a pipe, whereby the machine is charged with oil, and J the exit-pipe, leading from the receiver to the burner. l

The practical operation of this machine is as follows,

The tank B is filled with oil until it reaches the safety-pipe VK, which, as will be observed, allows the escape of oil before'it reaches the top of the tank. Hence the tank cannot befilled so as to run over into the adjoining compartment, and thereby injure the ap. paratus. lhe blower referred to is now actuated by any mechanical appliance, and thereby a current of air is forced into the cylinder through 'the pipe G, which, entering the mass of oil at the bottom, is blown through it, first passing through the perforation, whereby it is Vmore diffused, and consequently so atomized as to bring it more intimately in contact with the oil, from which it becomes charged with the hydrocarbonic element it contains, by this means converting the air into illuminating-gas, which escapes, as fast as generated, from the upper space above the oil to the gasometer orreceiver D, through the pipe E, entering at the bottom, and ascending', in the pipe, to the upper space of the float or cap of the gasometer, from which it is conducted out to the burner by the pipe J.

As an equal and uniform temperature is essential to a properconducting of the process, so that the fullest and most satisfactory results shall be obtained, the oil is kept surrounded by ashes, which, being a good nonconductor of heat.l lltlibute largely to a successful termination of the process. v

I am aware that gas has been generated by a similar process as the one above described, but the apparatus employed requires the use of water, i`or the' purpose of equalizing the temperature of the process. This use of water is a matter of much trouble and care, for the reason that the vessels holding the water must be made very tight, to' prevent leaking, and proportionately strong, which is attended with a large eX- pense, and therefore renders the machine too expensive for general use; also, in cold weather, theywater freezes, and, in consequence of its expansion, bursts the vessels, thereby so injuring the apparatus as to render it, for the time, useless but, by constructing this machine Awith a view of using ashes, or their equivalent, for the purpose specified, and in the manner as above described, no care need be taken to make the apparatus tight, for holding the ashes. Hence a much less eri# pensive machine can be made. The ashes are also a better non-eonductor of heat than water, and therefore answer a much better purpose in this respect, and, in cold weather, do not freeze, to the danger of bursting the apparatus.

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

The arrangement ofthe cylinder A, tank C, provided with induction and exhaust-pipes, and-'having the space H iilledwith a poor conducting-material, in combination with the perforated bottom and gasometer D,

as and for the purpose substantially as described.
