BOTTLE-STO PPER.

SPECIFICATION forming part of Letters Patent No. 360,467, dated April 5, 1887.

Application led August 18, 1886. Serial No. 211,226. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT I-I. PETERSON, a citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain Improvements in Bottle Stoppers, of which the following is a specication.

My invention consists of certain improvements in the construction of bottle-stoppers for which Iapplied for Letters Patent ofthe United States April 8, 1886, Serial No. 198,220.

Ihe main objects of my invention are to facilitat the closure of the bottle, to secure a tight closure, obviate liability of the stopper being opened by accidental blows, and to cheapen the construction. These objects I attainin the manner which I will now proceed to describe.

I n the accompanying drawings, Figure 1 is a side view, partly in section, of abottle-neck provided with my improved stopper. Fig. 2 is a similar view showing the stopper about to be closed. Fig. 3 isa view of the device on the fastening side.' Fig. 4 is a perspective view of the improved form of yoke and lever. Fig. 5 is avertical section of my bottle-stopper provided with an improved form of valve to adapt it for use with aerated liquids and showing the valve open, and Fig. 6 is a perspective view of the valve detached.

A represents the neck of the bottle,provided with the neck-wire a, to one side of which the stopper B is connected by a link, D, adapted t0A a loop or lug, b, on the stopper. I prefer to form this link ofthe same piece of wire as the neck-band a and to put a twist, d, in the link, so that should the fastening get slack it can be tightened at any time by increasing the twist. The lug` b on the opposite side of the stopper receives a curved link, E, for connection with the locking-lever F, which is adapted to act in connection with a yoke, G, secured to the outside of the bottle-neck by the neck-wire a.

The rubber portion B of the stopper, which is fitted over and held by the metal button in the usual way, is made concave on the under side, as shownin Fig. 2, in order thatwhen the stopper is forced down to its seat the rubber may more readily spread around the edge to form a tight closure, as shown in Fig. 1.

The link E, I make of the curved formillus trated in the drawings, and of spring-wire, so that it will constitute a spring, and when the stopper gets loose by repeated use or stretching ofthe wires or links it may be tightened up, and an increased pressure obtainedby increasing or restoring the bend of the wire-link E.

In my former stopper the link E is passed through an opening of the lever F; but in my presentinvention I dispense with the neccessity of drilling this opening by casting on the sides of the lever fingers e, which can Vbe cast in an openform, to be passed through eyes at the lower end of the two-armed link E, and then bent to form a closed eye, as illustrated in the drawings.

In my former stopper the yoke G was provided at its upper end with a notch for the introduction of the hooked nose of the lever F, and at its lower end with fingers g, for the protection and guidance of `lateral proj ectionsf on the lever F. In my present stopper I retain the protecting fingers and projections last referred to, but I replace the notch at the upper end of the yoke by a T-head, g', and fork the upper hooked end of the lever F for engagement therewith, so that the forks engage opposite sides ofthe T-head. By this construction the lever can be more readily engaged with the yoke to close the stopper, and when closed it is more firmly held, so that there is less liability of the stopper being opened by accidental blows.

IVhere the stopper is to be used for aerated liquids, I make use ofthe form of valve illustrated in Figs. 5 and 6. This valve consists of a small inverted cup, s, having secured to it spring-fingers s', hooked at their upper ends and preferably stamped out of sheet metal. These fingers are adapted to a vertical opening in t-he stopper, so as to allow a limited ver# tical play of the valve'toward and from the seat in the rubber of the stopper. The ,upper hooked ends of the spring-fingers come in contact with a shoulder in the opening in the stopper when the valve is open, as shown in the drawings.

In filling the bottle with aerated liquid, the stopper is iirst closed and the iilling-nozzle pressed into the opening in the top of the stopper, so as to keep the valve open during t-he filling operation. When the iillingnozzle is removed, the pressure on the interior of the bottle will close the valve by bringing its cup s against the seat formed by the rubber lining looking devices with e valve consisting of a ofthe stopper. cup, s', and hooked spring-fingers s', adapted I claim as my inventionto a vertical opening in the stopper7 all sub- I5 1.
