PRIMING-CUP.

Application filed June 7, 1915.

To all whom it may concern:

Be it known that I, EARL W. ROBERTS, a citizen of the United States of America, residing at 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, reference being had therein to the accompanying drawings.

The invention relates to priming cups for engines and has among the objects thereof to provide a valve-controlled priming cup which has a closure that is opened upon the opening of the valve and closed upon the closing of the valve; to provide such a type of valve-controlled priming cup that may be easily and cheaply manufactured; to provide a structure by which the open position of the valve will be indicated.

Other objects of the invention will more fully hereinafter appear.

The invention resides in the peculiar construction, arrangement and combination of parts as hereinafter set forth and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of the priming cup embodying the invention; Fig. 2 is a similar view showing the valve in open position; Fig. 3 is a longitudinal, central section; and Fig. 4 is a section on the line wcc of Fig. 3.

Referring to the one embodiment of the invention shown in the drawing, A designates the casing of the priming cup and B the cup proper, arranged at the upper end of the casing. Extending through the casing and communicating with the cup is a passage or conduit C, the passage in the structure illustrated extending longitudinally of the casing.

D is a valve controlling the passage C, the valve being herein shown as of the conical type, and E is a handle for actuating the valve to open and close the passage C by moving the port a of the valve into and out of registration with the passage.

It is found that if a closure is not provided for the cup, dirt, dust, grit and the like will collect in the cup, and when the priming liquid is poured into the cup the dirt, grit, etc., will be carried into the cylinder, which as will be readily appreciated, is objectionable. I have therefore, provided the cup with a closure, and in order to simplify the operation of priming, connect the Specification of Letters Patent.

closure so that it will be opened upon the openlng ofthe valve and closed upon the closing of the valve.

Referring more in detail to the particular construction shown in the drawings, which while a novel and very desirable form, is only one embodiment of the invention, G is the closure for the cup, in the form of a flat disk, and II is an arm extending laterally inward from the handle and carrying the disk. In the structure shown, the handle, disk and arm are formed of one piece, thereby permitting these parts to be stamped from a flat blank. As will be noticed upon reference to Fig. 2, the upper edge I of the cup is in a plane slanting in relation to the longitudinal aXis of the casing, and the closure is correspondingly arranged. This allows the olosure to be brought tightly into engagement with the upper edge of the cup upon a movement of the handle to close the valve. By properly twisting the arm the disk may be caused to accurately seat upon the edge I.

With the structure so far described, when the valve is closed as shown in Fig. 1, the closure will seal the upper end of the valve, and when the handle is moved to open the valve the closure will be removed from the cup.

In the type of valve illustrated, it is de sirable to indicate the open position of the valve. This I have accomplished without the addition of any parts. Thus the valve has a stem J that projects without the easing and upon which is sleeved a pair of washers K and L. Between these washers is arranged a spring M that is coiled upon the stem.

N is a cotter pin for limiting the outward movement of the washer K. This manner of holding the conical valve toits seat is usually employed in priming cups. The stem, however, is flat upon opposite sides and the opening O of the washer L is provided with flat portions P so that the washer will turn with the stem. Upon the inner face of the washer L is a projection Q which is adapted to engage a recess R in the casing when the valve is in open position, thereby indicating to the operator when the handle has been moved far enough to open the valve. Preferably two of these projections Q. are employed upon the collar at diametrically opposite points, and in such case two recesses R are formed in the side of the casing. In order to allow the Washer to seat tightly against the casing at the end of the valve when the latter is closed, recesses S are provided for receiving the projections Q in the closed position of the valve.

From the foregoing description it will be readily apparent that the structure is one which not only may be easily and cheaply manufactured, but provides very convenient means of closing the cup When the valve is not in use.

What I claim as my invention is:

1. I11 a priming cup, the combination'of a casing having a passage therein, a cup on the casing communicating with the passage, a valve in the casing controlling the passage, a closure for the cup, and a rigid connection between the closure and the valve for effecting the opening and closing of the closure upon the opening and closing of the valve respectively.

2. In a priming cup, the combination of a casing having a passage therein, a cup on the casing communicating with the passage,

a valve in the casing controlling the passage, a closure for the cup, and a connection be tween the closure and the valve for simultaneous'ly displacing the same from their closed to their open position and vice versa.

3. In a priming cup, the combination With a casing having a passage therein, of a cup upon the casing having the outer edge thereof in a plane slanting to the longitudinal axis of the casing, a valve Within the casing controlling said passage, a handle for said. valve, having rigid connection therewith, and a disk closure for said cup carried by said handle.

4:. In a priming cup, the combination with a casing, having a passage therein, a cup on the casing communicating with said passage, a valve in the casing controlling the passage, a closure for the cup, and a connection between the closure and valve for displacing the same about a common axis from their closed to their openpositions and vice versa.

In testimony whereofI afiix my signature.

EARL W. ROBERTS.
