ATTACHMENT FDR INTERNAL-COMBUSTION MOTQRS.
Application filed March 22, 1922." Serial No. 545,781
back fire through the carburetor assembly of the motor.
in carrying out the present invention itis my purpose to provide a device whereby back fire through the carburetor assembly of the internal combustion motor will be prevented and the gases incident to the back fire directed to the atmosphere without atfe-ting the carburetor.
it is also my purpose to provide a deviceof the class described which may be readily and quickly connected in the intake manifold between the carburetor and the motor cylinders and which will ope ate to auto' matically cut off communication betweenthe carburetor and the cylinders and automatically establish communication between the intake manifold and the atmosphere in the event of the back firing of the motor. thereby preventing the gases resulting from the back the passing through the carburetor.
A. further object of my invention is to provide a device of the character set forth which will embrace the desired features of efiiciency. simplicity and durability. which may be readily and quickly connected in the intake manifold of an internal combustion motor between the cylinders and the carburetor and which will embody comparatively few parts. and these so arranged and corelated as to reduce the possibility of derangement to a minimum.
With the above recited objects in view and others of a like nature my invention resides in the construction. combination and arrangcnient of parts set forth in and falling within the scope of the appended claim.
in the accom'panyiru drawings:
Figure l is a fragmentary side elevation of an internal combustion motor showing my invention connected in the intake manifold between the engine cylinders and the carburetor.
Figure 2 is an enlarged sectional view through my attachment Figure 3 is a horizontal setional view on the line 33 of Figure 1.
Figure l is a vertical sectional view on the line 4:et of Figure 1.
Referring now to the drawings in detail A designates a portion of an internal combustion motor equipped with an intake manitold a and a carburetor b.
interposed in the intake manifold between the carburetor and the engine cylinders my device indicated as an entirety by the reference character In the embodiment oi my invention selected for illustrative purposes my device compris s a vertically disposed valve chainber 1 cylindrical in cross section and having the upper end formed w'th a fastening flange 2 and the lower end formed with a s milar flange 3. These flanges 2 and 3 are bolted. or otherwise appropriately secured to the corresponding.tiaiiges 2 and 3 on the lower end of the intake maniiold a and the upper end of the outlet 5 of the carburetor, as clearly illustrated in Figures .1 and 2 of the drawings, thechamber 1 being of the same diameter as the intake manifold and in axial alinement therewith. in the present instance the inner wall of the chamber 1 adjacent to its lower end formed with an in \vardiy extending circular flange 4 formed to provide a valve seat 5, and engaging the valve seat 5 is an upwardly opening check valve 6. hinged or pivoted upon a pin 7 haviug the onus suitably seated. in the wall of the chamber 1. as shown in Figure 3. This alve 6 opens upwardly in the operation of the motor so that the cou'ihustible mixture may pass from the carburetor through the chamber 1 and the intake manifold to the cylinders of the motor.
in the present term of my invention the chamber 1 above the check valve 6 is formed with an outlet port 8. and integral with the wall "of this outlet portand extending therefrom at right angles to the chamber 1 is an outlet tube 9 having its outer end formed with an inturned flange 10 that provides avalve seat 11.
In this form of my invention the outer end of the tube 9 carries a valve chamber 12 of suitable construction and provided with L. The ,Wall of the chamber- 12 opposite from I "the outer end of the tube 9 is formed with ,aninwardlyextending guide tube l l'in axialfalinement with the tube 9, and in this immune M is slidably mounted the stem 50f a valve 16 engageable with the seat 11 :betvveen the valve .16 and the confronting end of the guide 14, the guide 14 being pro-- w-vided with openings 19 so that the air may eely escape from the guide in the sliding {of the stem 15 within the guide.
In'thepresent instance the lower wall v of the valve chamber 12 is formed with an nd normally engaging such seat under the faction of a spring 17 encircling the stem 15 f insane? in connection with t-he accompanying drawings, it will be seen that l have provided an attachment for internal combustion motors which will effectively prevent disturbance of the carburetor in the event of back fire and which will automatically cut ofi communication between the carburetor and the engine cylinders and establish cornmunication between the engine cylinders and the atmosphere, so that the gases from the back fire may be discharged'into the atmosphere. While I have herein shown and described one preferred form of my invention by way of illustration, 1 wish it to be understood that I do not limit or confine myselfto the precise details of construction herein shown and described, as modifications and variations may be made within the scope of the claim and without departing from the spirit In the operation of the motor the gases of my invention.
I claim:
A device of the class described comprising a chamber adapted for connection in the intake manifold of an internal combustion motor between the cylinders and carbureto 20 outlet port that is in open communication with an exhaust pipe18 that discharges into the atmosphere at some suitable point. 1
, are sucked into the engine cylinders from the carburetor lthrou h the chamber 1 and atmosphere.
the manifold and as ong as the engine operates normally the check valve 6 is held open incident to the continuous suction through the manifold. When, however,.a
back fire occurs the check valve 6 immediatelv closes incident to the pressure set up in the manifoldand the valve 16 is forced open by such pressure against the action of the spring 17, thereby permitting the gases from the back fire to pass through the tube 9,
valve chamber 12 and exhaust pipe 18 to the It will be noted that the spring 17 holds the valve 16 against its seat.normally, so
4 that in the normal operation of the engine the manifold is closed to the atmosphere, except for its connection with the carburetor.
From the foregoing description, taken a check valve in said chamber normally operating to permit the passage of gas through said chamber into the motor cylinders and operable to cut ofi communication bet-ween the motorYcy-linders and carburetor in the event of a back fire, a tube in open communication witli'said chamber, a check valve normally closing the'outer end of said tube and adapted to open to the atmosphere in the event of back fire, a valve chamber surrounding said last mentioned check valve, a guide .formed in said valve chamber, a stem for said-check valve working within said guide and a spring surrounding said check valve tohold the same normally closed.
In testimonywhereof, I affix my signature.
