UNITED STATES PATENT OFFICE.

PATRICK J. MCINTYRE, OF AUBURN, RHODE' ISLAND, ASSIGNOR TO UNITED WIRE AND I SUPPLY COMPANY, A CORPORATION OF RHODE ISLAND.

PRIMING DEVICE.

Application filed October 8, 1919.

T all whom it may concern Be it known that I, PATRICK J. MoIN- TYRE, a citizen of the United States, residing at Auburn, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Priming Devices, of which the following is a specification.

My invention relates to priming devices for use on internal combustion engines.

The essential objects of my invention are to render the device available for use upon V type motor without any danger of spilling the contents of the cup and likewise avoiding an inclination of the handle toward the operator; to insure a thorough locking of the retaining plate or washer and the consequent security of the assembled parts; to insure cleanliness and to improve the appearance of the structure.

To the above ends essentially my invention consists of such parts and such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification- Figures 1 and 2 are side elevations of my novel device showing the handle respectively elevated and depressed; and in the former a portion of a V cylinder,

Fig. 3, a vertical central section of the same,

Fig. 4, an enlarged similar section of a portion of the same,

Fig. 5, an end elevation of the plug, and

Figs. 6 and 7, details views of the retaining plate and cap.

Like reference characters indicate like parts throughout the views.

In detail 9 is the body of the primer provided with the usual terminal screw thread 10 for engagement in the engine cylinder, and having its upper portion 11 preferably enlarged and spherical to form a bearing.

The latter is provided with a transversely disposed tapered bore or seat 12 disposed at an incline to the body corresponding to the degree of inclination of the cylinder wall in which the nipple 10 is intended to be inserted. Rotatable in the seat 12 is a tapering plug 14 having one end preferably enlarged as at 15 to form a head. Near its other end the plug is of reduced diameter Specification of Letters Patent.

forming an annular shoulder 16 and a stem portion 17 The head 15 of the plug has. a radial hole 19 in which is tightly forced an arm 20 terminating in a semispherical cup 22 and disposed laterally at right angles to the plug. The parts 15 and 20 may be integral.

Extending centrally of the body is a longitudinal passage 24 adapted to register with an inclined port 25 in the plug, which in turn opens into an axial passage 26 in the latter and extends into the arm, whence a central passage 28 in the arm opens into the receptacle 22.

Adjacent the outer end of the stem 17 is an annular groove 30 forming resultant shoulders 31 and 32. A circular plate 34 is provided with a diametrical slot 35 having a curved end 36, the whole forming a horse shoe washer with arm portions 37. The neck formed by the groove 30 on the stem is a sliding fit in the slot 35 of the plate 34 and is adapted to normally seat itself in the portion 36 of the slot. For the purpose of locking this plate against escape caused by motor and other vibration, a cap is provided comprising, as shown in Fig. 7, a disk 39 with a central orifice 40 and a lateral flange 41 having a rounded edge 42. This cap is loosely mounted on the stem with the body 39 resting against the plate 34, and its wall 41 surrounding the latter and spaced slightly therefrom. In this instance a washer or cap 43 is loose on the stem adjacent the shoulder 16 and head 11. A hel ical spring 45 surrounds the stem with its ends 47 and 48 engaging the members 40 and 43.

The operation of my primer is as follows. In priming, the liquid is poured in the cup 22 in the position shown in Fig. 1, and descends through passages 28, 26, 25 and 24. The handle is then depressed to the position shown in Fig. 2 so that dirt is not accessible to the cup, and the port 25 is closed by being out of registration with the passage 24. To disassemble the parts the locking cap 40 is manually pressed inwardly along the stem portion 17 against the pressure of the spring, and as soon as the flange 41 reaches a point slightly behind the plate 34 the latter is pushed laterally out of engagement with the plug by pressure of the finger nail against the ends of the arms 37. All the parts of my device are then unlocked for disassemblage. It will be noted that assemblage and disassemblage may be effected Without tools.

It will be noted that by virtue of the inclined relation of plug 14 relatively to body or shank 9, the former is horizontal when the body is mounted in an inclined cylinder 50 at right angles thereto. Therefore both the handle and the cup are in a vertical plane.

I claim 1. In a priming device, the combination with an inclined cylinder, of a body mounted in the cylinder at right angles thereto, a

plug valve rotatably mounted in the body and disposed at an inclination to the body,

an arm upon the plug at right angles there- I to, anda cup upon the arm, said body, plug valve, and arm being provided With liquid passages communicating with the cup.

2. In a priming device, a body, a plug rotatably mounted, in the body, an operating arm on one end of the plug, said plug being provided near its opposite end With an annular groove, a plate provided With a diametrical marginal slot slidably embracing the plug in the groove, a disk slidably mounted on the plug contiguous to the plate, a flange on the disk surrounding the plate, a Washer on the plug adjacent the body, and a spring engaging the disk and Washer.

In testimony whereof I have affixed my signature.

PATRICK J. MoINTYR-E.
