JOSEPH CONTINENZA, 0F FAB-BELL, PENNSYLVANIA.

PRIMING our.

Apptlication filed April 3,

To all whom it may concern:

Be it known that I, JOSEPH GONTINENZA, a citizen of the United States, residing at Farrell, in the county of Mercer and State of Pennsylvania, have invented new and useful Improvements in Priming Cups, of which the following is a specification.

This invention relates to improvements in internal combustion engines, the particular nature of the improvement residing in an attachment in the form of an accelerator valve, whereby atmospheric air may be admitted to the engine through the intake manifold in predetermined quantities to regulate the air content of the fuel charge and provide a more perfect combustion.

Another object of the invention is the provision of an accelerator or air valve of simple construction, which may also be used as any engine primer and which may be adjusted to admit any predetermined amount of air and operate from a remote point (such as the instrument board of an automobile) to open and close the valve.

With the above and other objects in view, the invention further includes the following novel features and details" of construction, to be hereinafter more fully described, i1- lust-rated in the accompanying drawings and pointed out in the appended claim.

In the drawings:

Figure 1 is a side elevation of an internal combustion engine showing the intake manifold and the invention applied thereto,

Figure 2 is an enlarged sectional view on the line 22 of Figure 1 showing the invention in plan.

Figure 3 is an enlarged vertical section.

Figure 4 is a fragmentary section at right angles to Figure 3 of the lo er portion of the device.

Referring in detail to the drawings, where in like characters of reference denote correspending parts, the reference character 10 indicates an internal combustion engine whose intake manifold is shown at 11, while the carbureter is indicated at 12.

The manifold 11 is provided with an opening 13 for the reception of one end of a substantially L-shaped member 1 1, the latter having a threaded engagement with the opening 13 and being held in position by means of a lock nut 15. The member 14 is of sectional formation and includes a lower section 16 and an upper section 17, the former including an enlarged portion 1922. Serial No. 549,343.

18 having a bore 19. This bore is in communication with a substantially L-shaped passage or bore 30 provided in the section 16 and this communication is controlled by a rotatably mounted plug valve 21. The valve 21 is held in place as shown at 22 and is provided with an operating handle or finger piece 23, by means of which it may be moved to a position to close communication through the bore 20'or to open the same as desired. The enlarged portion 18 is provided with stops 24; by means of which the open and closed positions of the valve may be determined.

The section 17 of the L-shaped member 14; is provided with a bore 25 and when the sectlons are connected together as by a threaded engagement 26, this bore 25 will communicate with one end of the bore 20. The upper end of the bore 25 is surrounded by a relatively large air chamber 27 which is closed by a threaded cap 28, the said cap being provided with air inlet openings 29. At the upper end of the bore 25 there is provided a valve seat 30 which co-operates with the pointed end of a stem 31, the latter extending through and having a threaded engagement with the cap 28 so as to regulate the passage of air into the bore 25.

i The stem 31 is held in adjusted position by means of a lock nut 32 and is provided with a head 33 for convenience in adjustment. The cap 28 is surrounded by a flange 34: and the inner wall of this flange and the outer wall of the nut 32 provide an annular channel which surrounds the upper ends of the openings 29. By this means gasoline or other fuel may be poured into the chamber 27, the channel directing the fluid through the openings 29 so that the device may be used as an engine primer.

Connected to the handle or thumb piece 23 is one end of a rod 35, which may lead to the instrument board, of an automobile for convenience in operation.

In the use of the invention, the valve 31 is adjusted for the admission of a predetermined quantity of air and when it is desirable to use this air for the proper operation of the engine,'tl1e valve 21 is opened so that the amount of air passing from the air chamber 27 into the upper end of the bore 25 will be drawn through the manifold into the engine cylinders.

The invention is susceptible of various ch nge i s term, P pel-tine and m nor details of construction and the right is herein reserved to make such changes as proper- 1y fall Within the scope of the appended claim.

Having described the invention What is claimed is The combination with an internal combustion engine, of a primer cup therefor comprising a substantially L-shaped member enlarged at the juncture of its angle portions and heingprovided with a passage arranged v therethrough, said L-shaped member being threadedly secured to the intake manifold "and ineludingnpper and lower sections, a

cup shaped" member forming the upper seeture.
