My present invention relates to exhaust V cut outs ifor automobiles', or other vehicles propelled byexplos ve engines and has for its object to improve the same inv several particulars hereinafter. noted.

Generally stated, 'ithe invention consists of the novel devices,andcombinations-of devicesherei-nafter' disclosed and defined in the claims. or

Particularly theinventlon is directed-to an 7 improved actuatingf'connection' for the valve aet ngor inoveabl element of ,a cut out'device. This actuating connection includes a cable, the (term cable fb lngused in a broad and liberal sense to nclude'all such devices, as fo r example', wirecables ropes,

, disclosed and claimed inj'my priorjPatent Number 1,396,410, issued ofidate November 8, 1921; but is capable of more general'application to other types of cut out devices 1 As a further "important feature a cable guide is applied directly on the yoke or rela tively fixed, part of-the cut out device'so as i to thereby afford 1 a self-contained attach 4 ment vin which s aidcable guide may be ap-' plied at the factory and A A I second cable guide bracket thatwill be. supported from a suitable part of the vehicle'body an'd to which bracket the cable is adapted to be anchored in a position to hold the'valve acting out out element in a raised position against a limiting stop at which time the spring or yielding element F of the cable will be j stretched or put under strain and will then serve an important purpose. to be here n- "after more fully described. r r V n V In the" accompanying drawings which; 11- lustrate the invention like characters indicate like parts throughout the severalviews.
