Specification of Letters Patent.

Patented Dec. 16,1913.

Application filed January 11!, 1913. Serial No. 741,424.

To all whom it may concern:

Be it known that I, SHERMAN G. BERRY, a citizen of the United States, and a resident of Tyndall, in the county of Bonhomme and State of South Dakota, have invented a new and Improved Starter for InternaLCombustion Engines, of which the following is a full, clear, and exact description.

My invention relates to a starting construction for internal combustion engines, and the object thereof is to provide a starter comprising a pipe connected to supply air avarmed by the exhaust of the engine to the carbureter, and having means therein for vaporizing. a sufficient quantity of gasolene independently of the carburetor in order tofacilitate the starting of the engine in very cold weather.

Reference is to behad to the accompanying drawings forming a part of this spccifi cation, in which the same characters of reference indicate the same parts in all the views.

Figure 1 shows an end view, partly in section, of an internal combustion engine having my invention applied thereto; Fig. 2 is a view on the line 2-2 of Fig. 3, showing the warm air pipe carrying my starting device in longitudinal section; and Fig. 3 is a cross-sectional view on the line 3--3 of Fig. 2.

Referring to the drawings the numeral 1 indicates an internal combustion engine of any well-known type having a supply pipe 2 leading to the firing chamber from the carburetor 3. This carburetor is connected by a pipe 4 with a jacket 5 which may surround the exhaust pipe, this jacket of course communicating with the atmosphere so as to supply warm air to the carburetor when the engine is in operation.

In the pipe 4 is a valve or damper 6 connected to an arm 7 by means of which the valve is opened, and also connected to a spring 8, which normally acts to hold this valve in position to shut the pipe 4. Between this valve and the carbureter the pipe 4 is provided with a projection 9 having one end open and screw-threaded on its outside near the end thereof to receive a flanged ring 10, this flanged ring serving to secure a sheet of gauze over the end of the projection 9. This projection is likewise closed by means of a sheet of gauze 12, and between the gauze 11 and 12 is a body of porous ma erial for a purpose which will appear later. Between the projection and the carbureter the pipe 4 has an opening 14 over which is placed a sheet of gauze 15. Surrounding the pipe at this point is a sleeve 16 having an opening 17 which can be made to register with the opening 14. This sleeve is adjusted by means of a fingerhold 18 and rests upon a flange or collar 19 to prevent the dislocation of the sleeve 16. The upper end of the pipe 4: may have a sheet of gauze 20 to prevent the entrance of foreign substances from the jacket 5.

In operation the valve 6 is normally open so as to permit warm air to pass freely to the carbureter 3, but when the engine is to be started the arm 7 is released by means of a suitable link or lever connected thereto, and the spring 8 allowed to close the valve 6, The absorbent material 13 is now saturated with a su'lii'cient quantity of g'a'solene by pouring the same in through the gauze 11. The opening 14 must he closed and then the engine can be cranked. This causes air to be drawn in through the porous material 13 and through the carburetor to the supply pipe 2, from whence it passes into the firing chamber, providing a sufficiently rich mixture for ready combustion. As soon as the engine is running the valve 6 is opened and the fuel is supplied to the carburetor in the regular way. Of course in warm weather when there is no need for supplying warm air to the carbureter the velvet can be closed and air supplied through the opening 14. Furthermore, if at any time it is desired to clean the cylinder of the engine of carbon, this can be done by closing the valve 6 and pouring kerosene on the porous material 13. This oil will be carried into the cylinder and effectually remove any deposits on the inside of the same. My starter therefore not only facilitates setting the engine in operation by more readily vaporizing gasolene than can be done with an ordinary carbureter, but it makes it easier to clean the engine whenever cleaning is necessary.

I wish to have it understood that the above description is illustrative only, disclosing but one embodiment of my invention, and I do not care to be limited to the exact details shown and described, but reserve to myself the right to make whatever changes in the shape, size and arrangement of the parts as fairly fall within the scope and spirit of my invention.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a starting device, the combination of a conduit adapted to be connected with the firing chamber of an internal combustion engine, said conduit having a valve for controlling the admission of air thereto a d provided with a lateral opening, and a hflder for absorbent material secured to the ciinduit over the opening thereof, the absorbent material being adapted to receive hydrocarbon to be vaporized by air passing through the absorbent material into the conduit.

2. In a starting device, the combination of a conduit, .means for connecting said valve-controlled conduit to the firing cham-.

ber of an internal combustion engine, said conduit having an open-ended boss projecting laterally therefrom, and means for in closing a mass of absorbent material in said boss to receive hydrocarbon to be vaporized by air passing through said boss into the conduit and thence to the firing chamber.

3. In a starting device, the combination of a conduit, means for connecting said conduit to the firing chamber of an internal combustion engine, means for supplying warm air to said conduit, a valve for shutting off said warm air supply, another valve for supplying atmospheric air to said menses conduit when the warm air supply is not needed, and means carried. by the conduit between the valves for receiving hydrocarbon to be vaporized by air passing through the same into the conduit.

4. In a starter, the combination of a con- 7 duit, means for supplying warm air to said conduit at one end, means for connecting the other end of said conduit to the firing chamber of an internal combustion en giige, a Valve in said conduit for shutting off said warm air supply, a lateral hollow boss projecting from said conduit beyond said valve, means for inclosing a mass of absorbent material in said hollow boss to receive hydrocarbon to be vaporized by air passing into the conduit when the said valve is closed, said conduit having an opening beyond the boss, and a movable sleeve surrounding said conduit and having an opening therein to uncover or close the opening in the conduit, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
