Improvements in Funnels.
1, AUGUSTUS GERSDORFF, residing at 1906, 7th Street North West in the City of
Washington District of Columbia in the United States of America, Merchant, do
hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
Figure, 1, is a perspective view of my improved device.
Figure, 2, is a vertical, central section of the same in position for use, and
Figure, 3, is a horizontal section of the nozzle, upon line of figure, 2.
Letters of like name and kind refer to like parts in each of the figures.
In the use of funnels, much difficulty is experienced when filling a vessel through
the opening through which air must escape and various constructions of nozzle, such
as, the formation within its outer side of vertical or spiral air grooves, double walls etc.,
have been employed, but each of such constructions has proved defective, either from
the liability of the air passage to become clogged, or because of the cost of the article
and its liability to get out of order.
The design of my invention is to furnish in a simple durable and efficient form a
funnel which shall be as cheaply constructed as are those ordinarily used, and to this
end, said invention. Consists, principally, in a funnel provided with a nozzle which
has in cross section the form of a triangle, substantially as and for the purpose
hereinafter specified.
It consists, farther, in a funnel which has its upper edge curved upward and inward,
substantially as and for the purpose hereinafter shown. It consists finally in a funnel
which has its upper edge curved upward and inward and a nozzle that in cross section
has the form of a triangle, substantially as and for the purpose hereinafter set forth.
In the annexed drawing, A, represents the body of a funnel which has the usual
form except that its upper edge, a, has an upward and inward curve as shown. To the
lower end of said body is secured a nozzle, a¹, that has any desired size and amount
of taper, and from, its lower end upward nearly to the point of its junction with said
body has a triangular shape in cross section. When the funnel thus constructed is

page_text: used, its nozzle, in consequence of its triangular form, will find a firm bearing within
the opening, b, of a vessel, B, and between the sides of the latter and each of the faces
of said nozzle will be left a passage of such size and shape as to furnish a perfect
escape for the air which is displaced by the liquid that is poured into said vessel.
The air vents have such size as to prevent them from being choked by the spattering
of the liquid within said vessel, as would be the case were said vents smaller in size,
even though they were more numerous and in the aggregate had a larger area.
The
inward turned upper edge of the funnel prevents the usual slopping out of liquid,
should there be a want of care in pouring the same, and enables the device to be
safely used in place where the ordinary funnel could not be employed.
Flaving now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. A funnel provided with a nozzle which has in cross section the form of a
triangle, substantially as and for the purpose specified.
2. A funnel which has its upper edge curved upward and inward, substantially as
and for the purpose specified.
3. As a new article of manufacture, a funnel which has its upper edge curved
upward and inward and a nozzle that in cross section has the form of a triangle,
substantially as and for the purpose set forth.
