FREDERICK M. FURBER, OF BEACHMONT, MASSACHUSETTS.

P RIMING-cur.

To all whom t may concern Be it known that I, FREDERICK M. FUR- vBER, ,a citizen of the United States, residing at Beachmont, in the county of Suffolk and 4State of Massachusetts, have .invented cer-V tain Improvements" in PrimingCups, of which the following descript1on,1n connection 'with the accompanying drawings, isa specification, like reference characters on the drawings indicating like' parts in lthe In using a multi-cylinder engine ot' the internal combustion type it frequently happens that one or more of the cylinders stops firing or refuses to lire upon starting up the engine. It isdesirable of course to locate the cylinder that is not working so that the trouble can be determined and remedied. but such engines usually are not equipped with means'by which the operator can determine readily which cylinder is idle. The present 'invention aims to provide means by which this fact can be easily determined. The invention alsois directed to the provision oi' a prlmlngcup of novel construction. Preferably these two features are combined in a single device.

A convenient embodiment of the invention will now be described, reference being made to the accompanying` drawings, in which Figure 1 is a perspective view of a device embodying the invention; Fig. 2 is a central longitudinal section of the device shownin 1, but showing the lower portion of the device in side elevation; and Fig. 3 is a sec. tional view of the body of the device atyright angles to the view shown in 2, certain of the parts being shown in elevation.

The body 2 of the device preferably is made from square bar stock and is turned at its lower end and threaded to forni a stem 4 designed to be threaded into a suitable aperture in an engine cylinder. A large hole 6 is drilled in the upper end of the body and a smaller hole 8 is drilled through the body longitudinally thereof from the bottom of hole 6 to the lower end of the stem. The body also is drilled transversely to rcceive a valve plug 10 having a handle 12 which may be formed from the same stock asthe body 2. This handle is drilled as indicated at 14 to form a cup for the reception oie-priming liquid. The valve plug 10 has a diagonal duct 16 formed therein which connects with a short duct 1S opening into Specification of Letters Patent.

.the bottom of the vpriming cup l14. It will be evident that when the handle is in the p position in which it is shown in Figs. 1 and 2 the duct 16 will be in communication with the passage 8, but that when the handle is turned into the position indicatedin Fig. 3 the communication between the cup and the `passa-ge y8 will be cut off. The valve plug is heldin operative position in the body 2 by a, spring 20 and a Cotter pin 22.

The valve plug `10 is drilled as indicated at 24 to form an aperture which will register with the passage 8 both above and below the plug when thehandle is turned into the Iposition indicated in Fig. 3. The upper part of the passage 8 and the apertures 6 and 24 constitute a sight opening through which an observer may look into'the engine cylinder when the valve is in' proper position. This opening is closed to prevent the passage of gases therethrough by a bulls-eye 26 oit glass or other translucent material lwhich preferably completely fil-ls the hole 24 so that any .soot or deposit that collects upon the exposed surface of the bulls-eye will be scraped off when the valve is turned in the body.

It will be evident that when one of these devices is properly attached to each cylinder of an eiigine the engine may be primed by turning the handle 12 of one ,or more of these devices into an upright position for pouring the gasolene or other priming fluid into the cup 14. The memberV 12 thus serves not only as a handle but also as a priming cup. handle is then turned into a horizontal posi tion thus moving the bulls-eye into alinement with the duct 8 and closing the passage through the duct 16.

After the priming operation the4 If it is thenl found that one of the cylinders is running cylinder is not working by looking into the opening G of each device. Obviously if the cylinder is tiring properly he will see a flash at each explosion. The extension of the body above the bulls-eye 26 provides a comiaratively dark space around the bulls-eye, thus enabling the flash to be seen more distinctly.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent. of the United States is:

1. A. device of the lcharacter described, cmnprisng); a body constructed to be attached to an engine cylinder and having a a vave arranged to control communication between said priming cup and said passage, and a bulls-eye carried by said valve and arranged to prevent the escape of gases passage formed therethrough to communicate with the interior of the cylinder, a valve positioned in said ioody7 a buils-eye Carried by said valve and arranged to be moved into and outl of aiinement with said passage, and a handle for said valve recessed to iorm a priming cup, said valve heing constructed to controi the communication between said passage and said cup.

2. A device of the character described comprising a body constructed to be attached to an engine cylinder and having a passage formed therethrough to communicate with the interior of the cylinder, a priming cup,
