GEORGE F. CONNER,'OF PORT HURON, MICHIGAN.
'PRIMING-GUP.
Specificati nof Letters Patent.
Patented July is, 1913.
Application filed March 13, 1912. Serial No..683,497.
7 b all whom it may concern:
Be it known that I, GEoRoE F. CoNnnn, a citizen of, the United States, and a resident of Port'Huron, in the county of St. Clair and State of Michigan, have invented a new and useful Priming-Cup, of which the following is a specification. A
This invention relates to means for permitting the introduction of ,a charge of gasolene or other liquid fuel into the explo- 'sion chambers of internal combustion engines; and its object is to provide avsimple and e'tl'ective priming device which can be easily controlled, which can be filled without opening the passage to the explosion chamher, and which will be provided with ,a-passage thatmay be opened to'permit such flow, whenever desired.
A further object of this invention is to provide a priming cup which shall have straight passages, which may be easily cleaned, which shall have a cover toexclude dust and other impurities from the reservoir, and which may be attached to an engine without marring its polished outer surface.
In the accompanying drawing Figure l is a plan of this improved priming cup. 2 is a vertical sectionon the line 2-2 of Fig. 1. Fig. 3 is a bottom view of the cover. Fig. 4 is a plan of the body of the priming cup. Fig. 5 is an elevation of a tool which may he used to screw the priming cup into position. line 66 of Fig. 5.
Similar reference characters refer to like parts throughout the several views.
This priming cup comprises a body 3 ha ving a threaded lower end 4 which may screw into the cylinder head of an internal combustion engine so that the contents of the cup may flow through the passage 5 into the explosion chamber whenever desired. This cup is provided with an apertured top 7 and an internal enlargement or rib 8 which re ceive the screw-threaded stem 9. At the up per end of the stem may be formed any desirable handle 10, and its lower end 11 is made conical so that it will seat at the up per end of the passage 5.
A segmental cover 13 for the cup has a downwardly extending flange 14 to guide it on the body and an openin 15 to ermit the assage of the stem. It rther' as a proection 16 which extends down into the Fig. 6 is a cross section on the.
opening 17 in the body and limits the movement of the cover. A projection 18 may be formed on the flange 14 so that the cover.
- This spring also permits the cover to be turned withoutatiecting the stem 9 and by bearing against the handle 10 of the screw, prevents the'screw from turning from its predetermined position. This is of importance as the jarring of the engine usually causes all loose screws to turn, and would therefore change the adjustment of the screw 9 when this cup is used as a testroek.
WVhen it is desired to prime an engine, the cover 13 is turned until the opening 17 is ac cessible, whereupon the cup may be filled with alcohol, gasolene or other easily carbureted liquid. The cover can then he closed and the stem turned back to permit any desired amount of the fuel to flow through the passage 3. As the tapering end 11 will close this passage when the stem is screwed down, it will be apparent that the cover can be turned so as to permit an inspection of the contents through the opening 17 at all times.
The tool shown in l igs. 5 and o is designed to be inserted through the opening 17 in the top 7 and into the shell of the body of the cup, so that the cup can be screwed down into position without the use of tongs or clamps, which haxc a tendency to mar the outer surface of tittings of this type. For this reason the stem 20 oi" the wrench is formed as shown in Fig. U. A handle ill at the upper and ot' the stem permits the tool to be readily operated. The cup may therefore be made without any corners, thus permitting easy cleaning, and (-(uH'llK'C-S to eheapness of inanuhwture.
