HERBERT D. J UDKINS, OF DETROIT, MICHIGAN.
AUXILIARY ATE-INLET VALVE.
Specification of Letters Patent.
Patented Feb. 3, 1920.
Application filed October 4, 1916. Serial No. 123,652.
To all whom it may concern Be it known that I, HERBERT D. JUDKINs, a citizen of the United States of America,
residing at Detroit, in the county of Wayne and State of Michigan, have invented certaln new and useful Improvementsin Auxilary Air-Inlet Valves, of which the followlng 1s a specification, reference being had therein to the accompanying drawings.
This invention relates to auxiliary air inlet valves and'refers more particularly to a device attachableto the intake mechanism that the amount of opening is proportioned to the amount of opening of the throttle and is increased gradually as desired; to provide a separate mechanism for rendering inoperative the auxiliary air supply without interfering with the automatic control; to provide set screws or other adjustable abutment members which can be set to limit the" amount of opening or closing movement or both for the auxiliary air valve; to provide a construction which can be economically manufactured and easily attached in relation to the carburetor and the inlet manifold; and in general to provide a new and improved construction for increasing the cf ficiency of the fuel charge. V
The invention also resides in such features of construction and arrangement and combinations of parts as'will more full hereinafter appear.
In the drawings:
Figure 1 is a side elevation of a device embodying my. invention;
Fig. 2 1s a top plan view of the parts shown in Fig. 1.
Fig. 3 is an enlarged sectional View through the auxiliary air inlet valve.
Describing in detail the particular embodiment of my' invention shown in the drawings, A designates the inlet manifold of an englne and B the carbureter which is secured thereto by any suitable means such as the bolts C. These parts can be of any standard construction and the auxiliary an I .11 away from its seat.-
and open the valve inlet valve can be attached thereto in any convenient manner, although in the particular construction shown in the drawings, the construction and attachment of the auxiliary air inlet valve D in. fixed relation to the manifold and carbureter B is as follows:
The auxiliary air inlet valve comprises a main inlet chamber or ba-rrel E connected to a pipe F, screw threaded into the inlet manifold at F. Communication between the air chamber E- and the manifold through thepipe'F is controlled by a manually operable valve G, the stem of which has an eyelet G to which can be connected :1, wire or rod (not shown) leading to the dash or other convenient point for operation.
Normally the valve G is opened when the engine is running and the supply of air through the pipe Fis controlled by a valve H governing the inlet opening H in the barrel or chamber 11'. This valve has its inner end I tapered at I so that as the valve is withdrawn from the port H it will gradually increase the opening through which air is-admitted to. the chamber E and-pipe F. At its outer end the valve H is secured at J to a rock arm J. The latter is pivotally secured by a key J to a stud J carried by the chamber or barrel E. There is also mounted on the barrel E a guide K having a slot K within which the rock arm J extends; A spring K sleeved upon the guide K tends to normall force the valve hus if there was nothing to prevent the arm J from rocking, the spring K would normally hold the valve H open, but as it is desired to controlthe opening of the valve H from the operating.
arm L of the carbureter, the following construction is employed.
- The rock arm J extends beyond its pivot point and has a bearing L through which projects a set screw L The inner end L of the set screw is arranged in the path of the arm L and when the arm L is in closed position it will, through the action of the set screw and rock arm, hold the valve H to its seat. The amount of such closin can; however, be controlled by adjusting tfie set screw to project a' greater or lesser amount toward the rock arm. When the arm L is rocked to open the carbureter valve it will move away from the end L of the set screw and permit the sprin K to rock the arm J The amount of this opening is also controlled by a set screw M projecting through the lever J and having an end M abutting against the barrel or chamber E.
From the above description it will be obvious that the operator can by adjustment of the screws L and M control the amount of air which is automatically supplied to the fuel, and can also by operating the valve G control the auxiliary supply of air independent of the carbureter control. The particular construct-ion of the valve H Wherein its inner end is tapered so as to give a gradually increasing opening also forms an important feature of my invention, and in the preferred form the end of the valve is preferably slightly curved sozas to permit any desired degree of opening at a predetermined position of adjustment for the throttle valve. The invention, however, in its broader aspects, is not limited to this particular construction and various changes in this and other details of construction can be made within the scope of my invention.
\Vhat I claim as my invention is:
l. The combination with a member through which a fuel supply charge passes, of a valve for controlling the amount of fuel passing through said member, an operating device for said valve, there being an auxiliary air port for supplying additional air to said member, avalve member for varying the amount of air admitted through said port, an actuating device for said valve member, an adjustable member secured to said actuating device and positioned within the path of said operating device for operating said valve member in predetermined and adjustable relation to the operation of the first-mentioned valve.
2. The combination with a member through which a fuel supply charge passes, of a valve for controlling the amount of fuel passing through said member, an operating device for said valve, there being an auxiliary air port for supplying additional air to said member, a valve member for varying the amount of air admitted throughsaid port, an actuating device for said valve member, an adjustable member secured to said actuating device and positioned within the path of said operating device for operating said valve member in predetermined and adjustable relation to the operation of the first-mentioned valve, and a stop for limiting the opening movement of said valve member.
3. An auxiliary air inlet valve of the type in which the auxiliary inlet valve is operated automatically upon movement of the main control valve, said auxiliary inlet valve comprising a body portion having an auxiliary air inlet port, an axially movable valve having a tapered end controlling said port, a rock-arm pivotally connected to said valve, a spring for normally forcing said rock-arm in a direction to open said valve, a stop for adjustably limiting the opening movement of said valve, and a second adjustable member for governing the degree of opening of the auxiliary valve relative to the main control valve.
4. An auxiliary air inlet valve of the type in which the auxiliary inlet valve is operated automatically upon movement of the main control valve, said auxiliary inlet valve comprising a body portion having an auxiliary air inlet port, an axially movable valve having a tapered end controlling said port, a rock-arm pivotally connected to said valve, a spring for normally forcing said rock-arm in a direction to open said valve, a stop for adjustably limiting the opening movement of said valve, a second adjustable member for governing the degree of opening of the auxiliary valve relative to the main control valve, and a manually controlled valve for independently controlling the supply passing through said auxiliary inlet ort. p In testimony whereof I affix my signature.
