10 Claims. (Cl. 22S-22) 'Ihis invention relates to a mechanism for disnut I2, and the upper end of the plug, I5.

A sure is applied to the upper surface of the liquid washer, I6, is interposed between the upper end in the bttle, l, by means 0f the pump, as already of the fitting, I4, and the lower end of the plug, described.
I5; and a washer, I1, is interposed between the The liquid being thus under pressure and flll- 65 mg the ouuet tube, u, :2, sa, is ready to be dis- Y charged at will. Such discharge is controlled by means of a valve, 40, of tapered form, whose seat, 4I, forms a portion of a transversely disposed passage, 42, in the bottom wall, 1, of the pump cylinder casting. The valve, 40, has a stem, 43, terminating in a head or button, 44, and extending through a quantity of packing, 45, which is held in position in a recess or pocket, 46, cored in.the bottom wall, 1, of the cylinder casting. A spring, 41, reacts between the head or button, 44, and a washer, 48, overlying the packing, 45, and thus serves to hold the valve, 40, normally closed. The operating button, 44, is thus conveniently located so that when the neck, 2, of the bottle is grasped in the hand the thumb may be applied to the button, 44, so that a slight pressure thereon will open the valve, 40, permitting the liquid to iiow from the passage, 38, into the passage, 42, and through the discharge spout, 48, which is screwed into the threaded end of the passage, 42, as seen in Figure l.
A piston, 4, is shown as consisting of a pair of cup washers, 50, clamped between washers, 5I and 52, by rivets, 53, and this assembly is secured to the lower end of the hollow stem, 5, by a hollow plug, 54, having a head, 55, which may be of octagonal form, as shown in Figure 3. The hollow stem, 5, is anchored against rotation by engagement of an upturned lug, 5|, on the washer, 5I. with a notch, 5, in the lower end of said hollow stem. Just under the head, and gripped between it and thewasher, 52, I interpose a sheet metal member, 55, having an arm, 51, secured under the head of one of the rivets, 53, and having outwardly extending lugs, 58, disposed at such angles to each other that one of them may be aligned with one of the sides of the octagonal head, 55, when the latter is adjusted to its final position. As seen in Figure 3 this lug may then be bent against the ilat side of the head, 55, serving as "a nut lock to retain it. Another arm, 59, of the member, 58, is oiTset below the washer, 52, in spaced relation thereto and formed so that it can engage under the head, 58, of a screw set into the upper surface of the bottom wall, 1, of the cylinder. Thus, when the pump is not in use, the piston may be forced to the lower limit of its stroke and rotated until this lug, 58, hooks under the screw head, 50, so as to retain the piston in this position against the force of its spring, 8, thus rendering the device somewhat more compact and sightly with the cap, 23, of the piston stem disposed close vto the head, 8, of the cylinder.
As a matter of design, Figure 3 indicates that a portion of the post, 8, is cut away so that its external form is not truly cylindrical. This merely results from the fact that the chamber for the valve, 28, is so located that its circular outline would overlap that of the post, 8, and a portion ot the post is omitted to permit withdrawing the core for this valve chamber in making the cylinder casting. As seen in Figure 4, the stem, I0, is cored to contain both the air inlet passage, 28, and the discharge passage, 38, for the liquid, and the external form of this stem is approximately square with rounded corners, so that when the rubber plug, l5, is compressed around it, the square form of the stem will tend to hold the entire fixture against rotation in the neck of the bottle more firmly than it would be held by friction alone.
It will be seen that the device as described is compact and simple to apply to any standard bottle, and that it will be applicable to a considerable range of sizes of bottle necks by virtue of the adjustability of the soft rubber plug, I5. For tting the device to a still wider range of sizes one or more substitute rubber plugs of diilerent diameters may be supplied as a part of the outfit, if desired. The principal element comprising the pump cylinder, 3, and the stem, I0, being designed for manufacture as a die casting, may be produced economically, and the additional parts may be readily assembled without any extensive machining or fitting. While there is shown and described herein certain specic structure embodying the invention, it will be manifest to those skilled in the art that various modifications and re-arrangements of the parts may be made without departing from the spirit and the scope of the invention, and that the. same is not limited to the particular form herein shown and described, except in so far. as indicated by the appended claims.
I claim 1.
