PRIMING-CUP.

Application filed May 19,

T 0 aZZ whom it may concern:

Be it known that I, CHAnLns Gr. ANDER son, Jr., a citizen of the United States, residin at Buffalo, in the county of Erie and btate of New York, have invented certain new and useful Improvements in Priming-Cups; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in priming cups for internal combustion engines and has for its primary object the provision of means whichwill show the explosion taking place in the engine, so that a person can readily determine if the engine is properly functioning or if any one of the spark plugs employed is not firing.

Another object of this invention is the provision of a priming cup of the above stated character, which shall be simple, durable and efiicient and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination,and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a priming cup constructed in accordance with my invention,

Fig. 2 is a vertical sectional view of the same.

Referring in detail to the drawings, the numeral 1 indicates a cylindrical body having oppositely disposed sight openings 2 formed therein and has one end formed integrally with a flange 3 that projects inwardly and outwardly of said body as clearly shown in Fig. 2, and is formed integrally with a pipe or tube 4. The other end of the pipe or tube 4 is threaded within the priming opening 5 of an engine 6. A packlng or gasket 7 is seated on the flange 3 in the body 1 and has in engagement therewith one Specification of Letters Patent.

end of a transparent tube 8. The tube 8 is constructed from glass or any other material suitable for the purpose. The upper end of the body 1 is internally screw threaded to receive the screw threaded neck or' shank 9 of a priming cup 10. The priming cup 10 has formed adjacent the neck 9 a flange 11 which abuts the end of the body 1 when said neck is threaded into the body. A gasket or packing 12 is interposed between the upper end of the tube 8 and the neck 9. By the arrangement of the packings or gaskets 12-and 7 and the neck 9 being threaded into said body forms a leakproof connection between the tube and the body. VThe flanges 11 and 3 have their outer peripheries formed to provide wrench engaging faces so that a wrench or similar tool can be employed for connecting and disconnecting the various parts from each other.

' The priming cup 10 has a passage 13 extending therethrough and which is controlled by a valve 14 provided with a handle 15. The upper end of the priming cup 10 is flared or formed in substantially funnel shape so that fuel or explosive fluid can be poured into the same and allowed to pass through the passage, tube 8 and pipe 4 into the engine for the purpose of priming the same, and after priming, the valve 14: is closed which prevents the explosion and compression of the engine from escaping. By the sight openings 2 and the transparent tube 8 provided a construction which will display or show each explosion taking place in the engine whereby a person can readily determine if the engine is properly functioning or if the spark plugs are firing.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention what I claim is:

A priming cup comprising a cylindrical body having oppositely disposed sight openings, a flange formed on one end of said body and projecting inwardly and out wardly of the same, a pipe formed on said flange and in communication with the cylinder of an engine, a gasket on said flange In testimony whereof I afiix my signature lEyithin the body, a transparent tube in said in presence of two witnesses.
