SUPPLEMENTARY CARBURETER FOR FACILITATINGz'I-HE STARTING OF INTERNAL- To all whom it may concern:

Be it known that WALTER JAMES Booon- TON, engineer, a subject ofthe King of Grezt Britain and Ireland, whose post-office address is Thetford, Norfolk, England, has invented certain new and useful Improvements in Supplementary Carbureters for Facilitating the Starting of Internal-Combustion Engines,- of which the following is a specification.

This invention has for its object to provide a carbureting apparatus of very simple construction which can be easily fitted to the induction or intake pipe of the engine for supplying a primary or priming charge of etrol or other motive agent and air to facilitate the starting of the engine especially when it is cold, and consists of a small receptacle 0 ntaining material such as cotton waste, asbestos, Woo1, cotton wool, or

other surface vaporizing material; this reoep'tacle having a nozzle formed on one end and adapted to be fixed directly to the in- -duction pipe, and an air and petrol inlet formed in the upper end which is fitted with a cap or a valve which can be easily opened and closed or partly closed to admit air.

Supplementa carbureters for starting been previousl proposed wherein the starting charge 0 petrol was drawn or forced through a receptacle containing wire gauze, cotton waste or other similar material, and my invention is distinguished from these known devices in the followin respects 1. It 18 applied direct to the induction pipe without the intervention of lengths of tubing.

2. The air and petrol enter at'the same inlet, and no adjuncts such as pumps or compressed air cylinders are employed.

3. The whole device is much simpler to construct, and apply than the devices prereting apparatus or starter constructed ac-- cording to this invention.

Fig. 2 is an elevation of the same. The present invention comprises a hollow bod a having an apertured bottom I) adaptd fibr attachment to an intake or induction Specification of Letters Patent.

[COMBUSTIONENGINESm C a pipeof agas engine, the top of this hollow xially ody ,having a bearing [2 extendin therethrough and also having irfet' aper tures of extending,therethrough, the upper surface of the 'top beingdownwardly and inwardly inclined so as to conduct liquid fuel into the hollow body a through the apertures c. A valve'm is mounted to move longitudinally of the body a, and a valve stem 0 is connected to the valve and extends through the bearin p and is slidable therein so as to seat an unseat the valve m. A spring 9 is coiled around said valve stem and presses against said bearing and valve so as to yieldingly hold. the valve in its closed or seated position, and a bell crank n is pivotally mounted on the body a and is pivotally connected to the upper end of the valve stem 0. It will be seen, therefore, that the valve m may be operated by swinging the bell crank 11, on its pivot. I

WVithin the body a between its threaded end I) and the valve m, a mass of absorbent material i is disposed, this mass being sufiicient to entirely fill the space between two pervious members j'and la. The member is formed of wire gauze, and the member is preferably formed of wire gauze and cotton wick, and the pervious members j and k extend entirely across the body a so as to prevent any of the material 2' from passing outward beyond these pervious members. It will be seen, therefore, that when the valve m is open and liquid fuel is introduced through the apertures 0, such liquid fuel passes by gravity and capillary attraction into all parts of the absorbent material 2', air, drawn by the suction of the engine through the apertures 0', valve m, absorbent material and pervious elements 3' and k, and in thus passing therethrou gh, it mixes with the vapors from the liquid fuel so as to form a rich combustible gas, and this gas then Patented Maru25, 1919-. 1a plicationmed September21, 1918..seriainaasana.

What I claim as my invention is The combination of a hollow body having through lsaid inlet apertilre s, a valve in said:
