Application filed August "I, 1907. Serial No. 387,478.

Be it known that I, RALEIGH W. Gonrnnr, a citizen of the United States, residing at Oberlin, in the county of Lorain and State. f Ohio, have invented new and useful Improvements in Gas-Engine Starters, of which i the following is a s ecification.

This invention re ates to starters for gasolene and other explosive engines; and it has for its object to providean 1m roved device whereby a suitable charge 0 gasolene or other motive fluid may be injected into the Wit will readily appear as the nature of the invention is better understood, the same consistsin the improved construction, and novel engine cylinder in a suitably heated condition and withan admixture of atmospheric air, the mixture forming an explosive gas, ready tobe ignited by the igniting mechanism of the engine.

Special -objects' of thepresent invention are to simplify and improve the construction and o eration of this class of devices these and other ends in view which arrangement and combination of parts which Will'bB hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention; it being, however, understood ithat no limitation is necessarily made to the recise structural details therein exhibited, ut that changes, alterations, and modifications within the scope of the claims may be resorted to when desired.

In the'drawing: Figure 1 is a vertical sec tional view of the improved starter. Fig. 2 is an, endview of the same. I

Corresponding parts in both figures are denoted by -like characters of reference.

The improved starter comprises a suitable cup or reservoir 1 having a conveniently detachable cap or cover 2 and provided with a measuring chamber 3 of elongated tubular form located adjacent to the bottom thereof and preferably extending diametrically across .said bottom; The tube or barrel B which contains the measuring chamber isprovided adjacent to the ends of the latter with valve casings 4' and 5, the former of which commu 'nicates with the reservoir 1 through a port 6;

the casing 4' also communicates with the in: let end of the tube B throu h a port 7 and the casing 5 communicates wit the outlet end of the'tube B through a port 8. The casings 4 and 5 are provided wlth ordinary two way valves 9 and 10 which may be simultaneously turned to cut the measuring chamber 3 off from the ends of the tube While said Incasuring chamber is at the same time placed in communication with the reservoir 1 through the ort 6, this being the position illustrated in 1 y of the drawings; it will be readily seen t .at by a quarter turn of the valves, the measuring chamber will be cut off from the reservoir, while the ports connecting the measuring chambers with the ends of the tube or valve will be thrown open. The

movement of the valves may be simultaneously effected by means of cranks 11 suitably connected with the stems of the valves, and

connected with each other by means of a link 12 having a handle 13. A lug 14 extending downwardly from the barrel B carries a pan 15 in which a small quantity of liquid fuel,

- such as-alcohol, may be placed and ignited for the *P 0 6 of heating the measuring? chamber an its contents.

The inlet end of the barrel B is threaded, as shown at 16, for the reception of a connecte ing pipe or duct whereby it maybe conveniently connected with a storage tank, not

communication with the reservoir 1 w ch latter may be filled by removing the lid or shown, wherein atmospheric air is kept in cap 2. The contents of the measuring chamber me be heated by igniting a small quan? tity ofiquid fuel, such as alcohol, paced in the tank 15. The handle 13 is now manipulated to partially rotate the valves 9 and 1 Q,

whereby the measuring chamber will be cut off from the reservoir 1, and the contents of said measuring. chamber will be ejected by the current of compressed air from the source of supply previously referred to. The contents of t e measuring chamber will first enter into the chamber or s ace 17 and, with a free admixture of air, wi be forcibly projected through the apertures 18 into the firing end of the engine cylinder; Being previously heated, the fluid will readily combine with the atmos heric'air to form an explosive mixture w ich will be ignited in the usual manner, thus starting the engine.

The improved deviceis simple in construc tion, and it has been found to be thoroughly efficient for the purposes for which it is provided.

I claim:

1. A device of the class described comprising a reservoir, a tube or barrel adjacent thereto and containing a measuring chamber communicating with the reservoir through a port or duct, and two way valves in the tube or barrel adjacent to the ends of the measuring chamber, one of said valves being adapted to obstruct the port leading to the reservoir. 1

2.. In a device of the class described, a reservoir, a tube containing a chamber communicating with said reservoir, valves in the tube to cut ofi communication between the chamber and the ends of the tube, one of said valves being adapted to cut off communication between the chamber and the reservoir, a compressed air chamber at one end of the tube and a perforated Wall at the opposite end of the tube.

3. In a device of the class described, a

reservoir, a tubular barrel extending diametrically across the bottom th reof and having a chamber communicating therewith through a port or duct, valves or closures adjacent to the ends of the chamber, one of said valves being adapted to obstruct the port leading to the reservoir, cranks connected with the valve stem, a link connected to said cranks, and a heating pan sup orted beneath the chamber in the tube or arrel.

4. In a device of the class described, a reservoir, a tubular barrel extending diametrically across the bottom thereof and having a chamber c'ommunicatin r therewith through a port or duct, valves a jacent to the ends.

of the chamber, one of said valves being adapted to obstruct the ort leadin to the reservoir, a lug depending from the said tubular barrel and arranged intermediate the ends thereof, a heatin pan connected to the said lug, and a crank for effecting simultaneous movement of the valves.

In testimony whereof I aflix my signature in presence of two witnesses.

RALEIGH W. GODFREY.
