    Edwards Improvements in Stoppers /or Feeding Bottles and other Vessels. so as to close the air-passage which is formed through the stopper. The stopper shown at Figure 3 is in shape suitable for stopping the vent-hole of a beer or other cask, or it may be made of other forms to suit different descriptions of vessels. Having thus described the nature of my Invention, and the manner of 5 performing the same, I would have it understood that what I claim is the application of india-rubber springs to stoppers with passages through them closed by conical or suitable valves as herein described. In witness whereof, I, the said Henry Edwards, have hereunto set my hand and seal, this Nineteenth day of August, in the year of our Lord 10 One thousand eight hundred and fifty-eight.
