, PRIMING AND TEs INGc r.

To all whom it may concern:

Be it known that I, OSCAR A. SMITH, a

7 September 14, 1915 and in my contemporaneously 7 her 8, 191 Serial No. 200,869, it being an improvement in part particularly upon said application in that the present improvement has the important advantage that it can be used either with upright motors or motors that are'located at an angle, such as 8-cylinder and'12-cylinder motors, and can also be placed in the side of such motors instead of the top, if so desired, and also the further advantage that the valve stem extends through the device from end to end axially thereof.

A further important advantage resides in the fact that the device can be much less expensively made in view'of the elimination of certain features in my prior patent and applications. Y p

In my prior patent the cup therein shown necessarily hadto be inserted into the motor casing at the top thereof and the cups of myapplication Serial No. 200,869 were intended for use primarily with motors located at an angle to the perpendicular. While the present improvement is also intended for use with motors located at an angle to the perpendicular, nevertheless it can also be used to advantage with upright motors.

In the drawings accompanying and forming a part of this specification, Figure 1 is a vertical sectional view of this improved priming and testing cup, the dotted lines illustrating the valve partly open; Fig. 2 is a top view thereof; and Fig. 3 is a side view thereof.

Similar characters of reference indicate corresponding parts in the several figures of the drawing. V y In the present improvement, like that shown in my prior patent and application,

thevalve is maintained closed by'pressure thereon. Moreover, by reason of the construction, the carbon and soot cannot close or. clog up the opening or passage-way since any that forms on the valve is fractured sage, by reason of the manner in which the valve opens and closes, is entirely out ofi from the combustion chamber of the engine, and moreover by means of the present construction the valve is proof against leakage, so that it is always possible to easily manipulate the valve without liability of the carbon injuring the valve seat or valve, and

ception of awrench. The tubular portion is provided with exterior threads 5 at its lower end, so that'the'device may be turned into the motor and is also provided with a tapered valve seat 6 communicating with the axial or tubular passage-way 7 of the tubular portion 2. The cup portion 3 is provided at its upper end with an'opening 8 of less diameter than the tubular passage-way, but in axial alinement therewith, and this opening is provided with interior threads 9, and to one side of thisopening and inclined to the axis of the tubular passage-way the device is provided with a'oup or chamber 10 opening directly into the axial passage-way of the tubular portion and around the stem of the valve about to be described. This chamher is thus so located that even though the device may be placed at the side of,that is, horizontally intofthe.engine,-instead of at the top Or at an, angle thereto, the fluid will not'run out '7 7 j V It will be observed that the top 11 of the device is in a horizontal plane whilethe top 12 of the chamber is located inclined or at an angle to said top 11. I

Projecting through the threaded opening at the top and through the tubular passageway is a valve stem carrying at its lower end a tapered valve adapted to engage the valve seat hereinbefore described. This valve stem is provided'with threads at its upper end adapted to engage the interior threads 0 whenthe valve is opened, as the valve pas-' 9 of the opening 8. The valve stem is bent at an angle as at 13 to provide a suitable handle. 7

From the foregoing, it will be observed that the threads for locking the valve against its seat are located at the upper end of the device instead of at the lower end thereof as in my prior patent and applications, thus I am enabled to do away with certainmachine work heretofore required in forming grooves or slots communicating with the axial passage-way, while I am also enabled to provide a much larger opening for the passage of fluid through the valve since the valve stem does not have to be made enlarged at its lower end as heretofore for the purpose of carrying the threads as the threads at the upper end in the present structure are out of the way.

It will thus be observed that while retaining all the advantages of my prior patent and applications, I have provided an improved cup which can be used at the top or at the side of either an upright or a V-shaped motor, and also have materially simplified and lessened the machine work of such cups.

From the foregoing it will be seen that the present improved cup comprises a body portion having an axial passage-way therethrough from end to end and which body portion is provided with a passage or angularly located chamber which communicates with theaxial passageway of the body be low the top thereof, and which chamber is so located that whether it is in an upright, inclined or horizontal position, the fluid will not run out thereof except through such passage-way. o

Moreover it will be observed that the passage-way from its pointof communication with the chamber is larger than that portion of the passageway which is interiorly threaded and this provides not only means for the quick egress or" the fluid but for the proper assemblage of the parts since the valve stem, before the handle is bent and flattened may be readily inserted from the bottom of the cup into position, after Which, of course, the handle is bent, or flattened if desired, or both and this prevents the detachment of the handle from its proper position since the handle may be bent at just the right place to permit the valve to be opened to its full extent only.

- It will be understood that the various details may be more or less departed from without departing from the spirit or scope of the present improvement.

I claim as my invention:

1. A priming and testing cup comprising a two part device, one comprising a body having a passage therethrough and provided with a valve seat at its lower end and a chamber projecting to one side of and in communication with said passage below the top of said'body and so located'that the'longitudinal axis of said chamber is adapted to be placed in a vertical plane when the body is located in an inclined position, and the other a valve for closing said seat and having a stem extending through said passage, said body and stem having adjacent to the upper end of said body cooperating threads for holding the valve in its closed or open position, the diameter of the passage from the valve seat to its point of. communication with the chamber being greaterthan the diameter of the passage adjacent to said cooperating threads, the opening of the valve being effected by lowering said valve from its seat in the direction of the flow of the fluid through said passage, said body also having. exteriorly of its valve seat threads and al'sohaving a wrench receiving portion.

2. A priming and testing cup comprising a tubular portion having'exterior threads and a valve seat at its lower end. and haying at its upper end an angularly located chamher and also'having at one side of the upper part of said chamber an interiorly threaded opening, the topof said cup being in a planesubstantiallyparallel to the bottom thereof, and the top of said chamber being inclined to said top, a valve stem extending through said threaded opening and tubular portions and having a valve at its lower end, a handle at its upper end and threads adapted to engage said threaded opening. a

3. A priming and testing cup comprising a body having a passage therethrough from end to end and terminating at its lower endv in a valve seat and having at its upper end interior threads, avalve for closing said seat and provided with a'stem extending through said passage and having threads for engaging the interior threads ofsaid opening, said body havinganiofiiset chamber between its ends and in C-OImHUIIiOZIiZlOH with said pas sage below said interior threads and so located that the longitudinal axis of said chamber is adaptedto be placed in a vertical plane when the body is located in an inclined position, the, opening of the valve being efl'eoted by loweringsaid valve from its seat inthe, direction of the flow of the fluid through said passage.
