Specification of Letters Patent. I Patented Dec. 2'7, 1910.
Application filed March 31, 1910. Serial No. 552,498.
Eb all whom it my concern:
Be it known that 1; Fans Anosnson, of Cambridge, in the county of Middlesex and State of lilassaclmsetts, a citizen of the United States, have invented a new and use Improvement in Funnels, of which the specification. a 1 to a funnel tor filltenk or other receptacle having avalve which closes to indicate when the tank is full as well as to retain any surplus liquid in the when it is thereafter removed the tank, and the embodiment of it n the drawings is especially intend lling gasolene tanks for aucomprises a. lunnelhaving a .iioh is closed by a float operated by he liquid in the tank tennis constructed as there shown in l igure ion of the lower part of the n its throat the valve being open.
similar view showing the positlie when the float has been fl hievalve, also showion oi and clo dotted lines the position otthe float l is awn out from the tank.
e at right angles 1 s is a section on 5 is an enlarged le er.
A the funnel he low-er portion only of which is shown, the lower end of said funiiel being provi ed with the usual throat A which h; preferably cut away at one side as .hown at A".
B is a valve seat.
l is the valve which as shown is a ball and which in its preferred form is constructed of metal so asto have some appreciable weight.
c is a valve rod. which extends down through an opening-.5 in the cross bar B which serves to keep it approximately centered.
D is 2-. lever which is pivoted upon a rod E menu A across the throat of the funnel.
T s le er as shown comprises two members i med together at one end by the part d "and at the other end by the part d these parts being located on opposite sides of the members of the lever, the part al beingment of the valve rod 0 which is pivoted to that end of the lever D. The float arm F is pivoted to the other end of the lever D and the part 0? serves as a stop to limit the movement of the float arm F. The float arm carries a float F at its lower end.
VVhen'this funnel is to be used the parts are set in the position shown in Fig. 1, that is to say, the valve is raised by hand or otherwise, thus extending the lever D into the position shown in Fig. 1 where it will be noted itis slightly overbalanced by the weight of the valve C and its rod 0, the lower end of the rod resting against the stop d so as to prevent the valve from dropping. The float F depends from the other end of the lever D. The tunnel is then placed in the opening 9 in the tank. or can G and the process of filling is then carried on in the usual way. When the level of the liquid in the can reaches the float F the float begins to rise with it as shown in Fig. 2 where H indicates the level of the liquid. As the float rises however it engages the stop (Z on the lever D and thereby turns the lever D so as to throw the pivot cl 't'rom its position in Fig. 1 to the left of the axis E of the lever D. There being nothing then to support the valve C it closes quickly by its own weight so that the parts assume the position shown in Fig. 2, the funnel at this moment being perhaps partly filled with liquid. No liquid can escape however'be'tween the valve and its seat and the user seeing that the valve is closed and also, where the parts are made of metal hearing the closing of the valve, lifts the funnel out from the tank during which operation the float assumes the position shown iii-dotted lines in Fig. 2 so that it will be drawn out from the tank with the funnel. As the float F is light in'comparison with the weight of the valve C the lever 1) remains in the position shown in Fig. 2 until the parts are re-set in the position shown in Fig. 1 to empty the funnel or for use again.
The above is the simplest form of my invention now known to me but I do not mean to confine my invention to thisform of embodiment, my invention consisting broadly valve and a float whereby under ordinary conditions the valve will be held open and only allowed to close automatically when the float is lifted.
What I claim as my invention is: v 1. The funnel above described having a throat provided with a valve seat,a valve to close against said seat, a trip lever pivotally mounted in said throat, one end of said tri-p lever being pivotally connected to said valve and a float pivotally connected to the other end of said trip lever.
2. The funnel above described having a throat provided with'a valve seat, a valve to close against said seat, a valve rod, a trip lever pivotally mounted in said throat, one end of said trip lever being pivotally attached to said valve rod and a float pivotally connected to the other end of said trip lever.
3.'The funnel above described having a throat provided with a valve seat, a valve to close against said seat, a valve rod, a trip lever pivotally mounted in said throat, one
end of said trip lever being pivotally attached to said valve rod and a float pivotally connected to the other end of said trip lever and having a limited movement with relation thereto.
4. The funnel above described having a throat provided with a valve seat, a valve to close against said seat, a valve rod, a trip lever pivotally mounted in said throat, one
. end of said trip lever pivotallyconnected to said valve rod and having a limited move ment With relation thereto, and a float pivotallv connected to the other end of said trip lever and having a limited movement 'With relation to said trip lever.
