GUY L. KENNEDY, OFSAN FRANCISCO, CALIFORNIA, ASSIGNOB TO NATIONAL CAR- BONATED vLIQUID (70., OF SAN FRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA.

Specification of Letters Patent.

Patented June 21, 1910.

Application'fllefl September 2, 1909. serial No, 515,976.

Be it known that LGUY L: KENNEDY, a

citizen of the United States, residing at San Francisco, in the county of Sanhrancisco and Stateof Californian-have invented new and useful Improvements in Fillers for Siphon-Bottles, of which the following is a specification.

The object of the present invention is to provide-a simple, convenient, and efiicient evice for filling siphon bottles with carbonated liquid. A I

In the accompanyin drawing, Figure 1. is

a vertical section of t e filler, showing the" parts in osition when the filler is not in use, certain parts bein shown in side elevation: Fig. 2 is a simi ar .view showing the parts when in use.

Referring to the drawing, 1 indicates a flexible tube which is connected to the source of sup ly of carbonated liquid. An end of said tu is secured upon a depending cylindrical extension 2 of a casing 3, on the upper end of whichv is screwed a cap 4 having an inwardly converging mouth or guideway 5, which is, adapted to guide the end of the spout 6 of the siphon bottle intoa central position. Between said cap 4: and the end of the casing is secured a flange? of a rubberv gland 8, centrally apertured, as shown at 9 said a erture belng adapted to receive and fit tig tly around the extreme end of said spout. The inner surface of said casin is formed with a groove 11, within whic is received a flange 12 of a rubber check valve 13, which, while, so far as I am aware, novel, forms the subject of a separate application, and is not claimed herein. It comprises, in addition to said flange 12, a central conoidal portion 1 1 which is received within a reuced portion 15 of said casing 3, said re duced portion forming a comparatively wide shoulder 16 against which the flange 12 rests.

The apex of said conoidal. portion is formed flange 12 of said check valve is additionally secured in place by means of a disk-shaped screw plug 18,. screwed into an internally threaded .portion of the casing. Said screw plug is centrally apertured to permit to pass therethrough a filling tube 19, the upper end of Which is secured to a disk 20, which slides within the inner surface of the casing andacts as a guide, and which is pressed against the inner side of the gland 8 by a helical spring 21 around said filling tube and compressed between said disk and the pipl osite surfaceof the screw plug. Said in whic is inserted within the entrance to the check valve and is held in. place by the resiliency. of the rubber thereof, the filling tube extending within the check valve .to a

' point close to the transverse slit there- ,through, but not sufliciently to open the same unless it is depressed.

To fill a siphon bottle, the filler is removed so' that the end of the siphon spout passes into the converging mouth 5 and then through the aperture 9 in the rubber gland tube passes throu h a bushing 22,

8 and impinges against the disk 20, surrounding the end of the filling tube projecting through said disk. Further pressure against the end of the spout causes the disk to be pressed inward against the action of the spring 21, carrying with it the filling tube 19, the effect of which is to open the slit 17 in the apex of the check valve, thereby forming a communication between the source of supply of aerated liquid and the siphon bottle. The aerated 1i uid then passes through said extension 2, fi lin tube 19 and spout 6 into the siphon bottle the siphon valve (not shown) being heldopen when filling the bottle. Upon withdrawing the siphon spout from said filler, the spring 21 immediately restores the dislt'20 to its place in contact with the gland 8, thus withdrawing the filling tube from the check valve 13, which immediately thereupon closes. The check valve in this combination forms an important feature of this invention, on account of the rapidit and certainty with which, when withdrawing of filling tube, the lips of the check valve close the instant that the filling tube is withdrawn, absolutely cutting off any further passage of the liquid therethrough, the pressure pf the aerated liquid against the outer side of the check valve then only serving to maintain the check valve closed.

I claim .1 I

1. An apparatus of the character described, comprising a casing, a su ply tube secured to one end thereof, a cap c osing the other end thereof, having an inwardly converging mouth, a rubber gland'secured be- "of said fillin tween casing and cap, a-check valve secured within said casing,- havin a hollow central conoidalportion 'slit'ted t rough its apex, a filling tube withinsa'idcasing open at both ends, a disk secured to sai tube, and a spring arranged to press said disk againstsaid gland, the other end of said tube extending -.into said hollow conoidal portion of the valve, substantially as described.

2. An apparatus of the character'described, comprising a casing, a supply tube secured to one end thereof, a cap secured to the other end and formed with an in-' wardly converging mouth, a centrally apertured gland between said cap and casing,

a centrally apertured rubber check valve open at both ends,

scape? scribed,-comprising a casing, a supply tube secured to one end thereof, an apertured cap secured to the other end, a centrally apertured gland, the flange of which is secured between said cap and easing, a check' valve having al'flange secured within the saidcasing and havin a hollow central co- =noidal portion slitted t rough its apex, a re taining disk on'the said valve, a filling tube around the tube and between the two disks,

the other end of the tube normally projecting into the hollow portion of the check valve,substantially as described.

In testimony whereof I have hereunto set my hand'in the presence of two subscribing witnesses. V
