- the cup or fluid container shown is formed-integral by suitable dies and comprises the upper cup-shaped part 10, the intermediate part 11 of reduced width, and the end 12, the intermediate part 11 being polygonal for receiving a wrench, and the end 12 being threaded to fit a tapped opening leading to the place into which it is desired to charge priming mixture such as gasolene.
- the base 13 is the'outlet passageway 14, this passageway being controlled by the conical end 15 on the valve stem 16 which extends axially through the cup.
- the stem along its intermediate part has the thread 17 and confined within the cup structure is a nut member 18 through which the stem threads so that turning of the stem in one direction or the other by means of its handle 19 will cause opening or closure of the outlet passageway 14.
- the nut member 18- in the cup structure is of sheet metal and is formed by bending and drawing a metal disk. The central part of the disk is drawn down to form a cylindrical shank 20, the surrounding section 21 being preferably conical to seat against the conical shoulder or base 22 between the cup section 10 and the intermediate section 11 of the cup structure.
- the sides of the cup section 10 a short distance above the base 22 are deflected inwardly to a diameter less than that of the upper edge of the conical section 21 of the nut member. the nut member being then movable vertically between the base 22 and the horizontal plane where it will abut against the wall of the cup section 10.

- the valve stem When the valve stem is raised to open the outlet 14 the conical part of the nut member will seat on the conical base 22 and will support the stern in its raised position so that liquid poured into the top of the cup structure will flow down through the openings 25 and 26 originally occupied by the sections 23 and 24 and will then flow through the sections 11 and 12 and through the outlet 14 into the engine cylinder.
- the nut member When the valve stem is screwed downwardly and its conical end abuts against the base 13. the nut member will be raised until it is stopped bv engaging the wall of the cup section 10. However, before such engagement, the nut member permits free lateral movement of the stem to accurately center its end 15 in the outlet 14: to assure accurate and tight closure thereof upon further turning of the stem after abutment of the nut member against the cup wall.
- the stem below the threaded section thereof is of sufficiently reduced diameter to pass readily through the threaded shank of the nut member so that the stem can be readily entirely withdrawn.

As shown on the drawings it'is rigidly secured, it being polygonal to fit against the polygonal sides of the section 11 and being held against the vertical movement by ears 28 which may readily be formed by forcing down sections of the metal from the side walls of the cup section 11. Where the nut member is thusrigidly secured against the vertical or lateral movement, the threaded engagement of the valve stem 16 in the threaded opening 29 of the nut member may not be such as to assure accurate seating of the valve in the outlet 14 if the valve end is rigid on the valve stem as in the structure of Figs. 1 to 4.

Application filed December 13, 1917. Serial No. 206,997.
To all whom it may concern:
Be it known that I, EDMUND NOLAN, a
citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Priming Cups, of which the following is a specification.
My invention relates to priming cups which are particularly adaptable for attachfor charging priming fluid into the-cylinders, the object of the lnvention' being to provide improved construction, arrangement and operation of valve, mechanism for opening and closing the cup outlet.
My invention will be fully understood specification and the accompanying drawing, in which drawing Figure 1 is atop view of a cup with part of the valve handle broken away,
Fig. 2 is a sectional view on plane 2-2, Fig. 1, showing the valve closed,
FFig. 3 is a sectional view on plane 33,
Fig. 4 is a sectional view on plane 2-2,
Fig. 1, showing the valve open,
Fig. 5 is a top view of a modified form of cup with part of the valve handle broken away,
Fig. 6. is a sectional v ew on plane 6-6, Fig. 5, and
Fig. 7 is a sectional view on plane 7-7, Fig. 6.
The cup or fluid container shown is formed-integral by suitable dies and comprises the upper cup-shaped part 10, the intermediate part 11 of reduced width, and the end 12, the intermediate part 11 being polygonal for receiving a wrench, and the end 12 being threaded to fit a tapped opening leading to the place into which it is desired to charge priming mixture such as gasolene. Through the base 13is the'outlet passageway 14, this passageway being controlled by the conical end 15 on the valve stem 16 which extends axially through the cup. The stem along its intermediate part has the thread 17 and confined within the cup structure is a nut member 18 through which the stem threads so that turning of the stem in one direction or the other by means of its handle 19 will cause opening or closure of the outlet passageway 14. It is very important that the valve accurately through the-cup when the engine is running. I therefore float the nut member 18- in the cup structure, that is, this member has limited freedomof movement so that the valve stem will be self-centering to accurately close the outlet 14. As shown in Figs. 1 to 4, the nut member is of sheet metal and is formed by bending and drawing a metal disk. The central part of the disk is drawn down to form a cylindrical shank 20, the surrounding section 21 being preferably conical to seat against the conical shoulder or base 22 between the cup section 10 and the intermediate section 11 of the cup structure. To permit limit d movement of the nut member in axial direction, the sides of the cup section 10 a short distance above the base 22 are deflected inwardly to a diameter less than that of the upper edge of the conical section 21 of the nut member. the nut member being then movable vertically between the base 22 and the horizontal plane where it will abut against the wall of the cup section 10. In order to limit the lateral freedom of the nut member sections 23 and 24 are stamped out of the conical part 21' and deflected downwardly against the threaded shank which ,receives the valve stem so as to increase the width of the shank at this point to almost that of the interior of the polvgonal section 11. The sections 23 and 24 extend into this polygonal section and are of.a width a suiticient distance less than the width of a side of the polygonal section to permit. lateral movement of the nu m mber. the n member being then free for limited lateral movement within the section 11 but prevented from turning by the sides of such section. When the valve stem is raised to open the outlet 14 the conical part of the nut member will seat on the conical base 22 and will support the stern in its raised position so that liquid poured into the top of the cup structure will flow down through the openings 25 and 26 originally occupied by the sections 23 and 24 and will then flow through the sections 11 and 12 and through the outlet 14 into the engine cylinder. When the valve stem is screwed downwardly and its conical end abuts against the base 13. the nut member will be raised until it is stopped bv engaging the wall of the cup section 10. However, before such engagement, the nut member permits free lateral movement of the stem to accurately center its end 15 in the outlet 14: to assure accurate and tight closure thereof upon further turning of the stem after abutment of the nut member against the cup wall. The stem below the threaded section thereof is of sufficiently reduced diameter to pass readily through the threaded shank of the nut member so that the stem can be readily entirely withdrawn. The upper conical part 21 of the nut member also serves to guide the stem into the threaded shank. The entire construction is very simple yet substantial.
In Figs. 5 to 7 I show a modified arrangemeht. Here the nut member 27 is entirely Within the polygonal section 11 of the cup structure and may or may not be rigidly secured. As shown on the drawings it'is rigidly secured, it being polygonal to fit against the polygonal sides of the section 11 and being held against the vertical movement by ears 28 which may readily be formed by forcing down sections of the metal from the side walls of the cup section 11. Where the nut member is thusrigidly secured against the vertical or lateral movement, the threaded engagement of the valve stem 16 in the threaded opening 29 of the nut member may not be such as to assure accurate seating of the valve in the outlet 14 if the valve end is rigid on the valve stem as in the structure of Figs. 1 to 4. I therefore preferably provide a movable or floating valve 30. As shown, this valve is cylindrical and has the conical lower end 31 and the spherical socket 32 in its upper end for receiving the ball 33 at the lower end of the valve stem. \Vith' this arrangement the valve is free to accurately fit and close the outlet 14 when the stem is turned down. It is evident that instead of rigidly securing the nut member. its width could be such as to permit lateral freedom and the ears 28 formed to permit vertical freedom of the nut, and then it would be unnecessary to provide a floating valve. To permit flow of fluid from the upper cup section 10 past the nut grooves or channels 34 are formed in the nut sides. I
As shown, the nut may be placed in the lower end of the cup section 11 to leave the space 35into which a socket wrench can be inserted for attaching or removing the cup if'this location is such as to make it impossible to get a wrench on the outside of the section 11. 2 The diameter of the valve 30 is such that the stem can readily be withdrawn through the nut opening to permit the insertion of a socket wrench.
I do not desire to be limited to the exact construction, arrangement and operation shown and described as modifications could no doubt be made which would still come within the scope of the invention. I claim as follows:
1.. In a priming cup structure, the combination of a cup body having an outlet at its lower end, a valve stem extending axially through said body, a valve for said outlet controlled by said stem, said stem having a threaded section, and a nut receiving said threaded section and confined within said body against rotation but with limited freedom of lateral movement whereby to permit said stem and valve to cooperate to .accurately close said outlet.
