Description

UNITED STATES PATENT OFFICE.
KNUTE J. JOHNSON, OF MINNEAPOLIS, MINNESOTA.
CUT-OUT VALVE.
Application filed February 17, 1919.
out valve, especially adapted for use in con"' nection with the exhaust pipes of internal combustion engines.-
To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.
In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings,
Figure 1 is a fragmentary view showing the invention applied to the exhaust pipe of an internal combustion engine; and
Fig. 2 is a view principally in section taken on the line 22 of Fig. 1.
The numeral 3 indicates the exhaust manifold of an internal combustion engine and leading therefrom is an exhaust pipe which opens into a muflier 5. Rigidly secured to the exhaust pipe l, are two longitudinally spaced collars 6 and 7. Formed in oneside of the exhaust pipe 4, quite close to the collar 7 is a cut-out port 8.
A sleeve-like cut-out valve 9 is mounted on the exhaust pipe 4 between the collars 6 and 7 for opening and closing the cut-out port 8 by an axial sliding movement on said exhaust pipe. Encircling the exhaust pipe 4. and compressed between the collar 6 and adjacent end of the cut-out valve 9, is a coiled spring 10. This spring 10 yieldingly holds the valve 9 seated against the collar 7, in which position of said valve, the port 8 is normally closed thereby.
To cause the cut-out valve 9 to freely slide on the exhaust pipe 4, the inner intermediate face thereof is cored out at 11, so that only the end portions of said valve bear on the exhaust pipe 4 at opposite sides of the port 8, and thereby form tight joints between said valve and exhaust pipe. It will be noted Specification of LettersPatent.
Patented Feb. 24, 1920.
Serial No. 277,555.
that the bearing surface of the valve 9, adjacent to the collar 7, is made considerably narrower than the bearing surface at the other end thereof, for the reason that such end of said valve bears against the collar 7 and thereby afiords an additional tight joint between the valve and exhaust pipe.
The cut-out valve 9 is opened against the tension of the spring 10 by a rod 12 actuated by a foot pedal or other suitable means, not shown. Said pedal will, of course, be provided with suitable means for locking the cut-out valve open. The operatin rod 12 is attached to the cut-out valve 9 by orming thereon an eye 13, which fits over a radial stud 14 on said valve. 'A cotter pin 15 is inserted through a bore in the stud 14, outward of the eye 13 to hold the rod 12 on said stud.
The above described invention, while extremely simple and of small cost to manufacture, has, in actual usage, proven highly eflicient for the purpose had in view.
What I claim is 1. The combination with the exhaust pipe of an internal combustion engine, of a stop collar on the exhaust pipe, said exhaust pipe having formed therein in the vicinity of said collar a cut-out port, a sleeve valve surrounding the exhaust pipe with freedom for axial sliding movement thereon, a spring yieldingly holding said valve in a position to normally close said port and seat against said collar, and a connection for opening the valve against the tension of the spring.
2. The combination with the exhaust pipe of an internal combustion engine, of a pair of longitudinally spaced stop collars on the exhaust pipe, said exhaust pipe having formed therein between said collars a cut-out port, a sleeve-like cut-out valve surrounding the exhaust pipe with freedom-for axial sliding movement thereon, a coiled spring encircling the exhaust pipe and compressed between the valve and one of said collars and vieldingly holding said valve against the other of said collars to close said port, and a connection for opening the valve against the KNUTE J. Jonusou.
