` Application led Hay 12, 1928. Serial-J27L7-28.-
My said invention relates to an improved air valve of the collapsible type and the method of making the same, and aims te provide a simple and 'expeditious method of making such article with a viewto producing a valve which will be extremely inexpensive and proof against leakage. Such valve .are-quite extensively used for inflatable bodies such for "example as the bladders of foot balls, volley balls, etc'. i i
The invention includes the novel method and article hereinafter described and particularly defined by .the appended claims.
What I at present consider the preferred embodiment of the 'invention is illustrated in the accompanying drawings in which:
Figure 1 is a side elevation of a portion of a bladder containing myimproved valve.
Fig. 2 is a sectional detail vpartly broken away. l
Fig.'3 is a section at right angles to Fig. 1. Fig. 4 is a section on line 4-4 of Fig.4 2.v In proceeding according to my improved method I provide two sheets -1 and-1n of flexible material impervious -to air, and of the proper'length, breadth` and thickness according-tol size of valve desired. The material preferable for the purpose is soft vulcanizedrubber.
These sheets are superposed on each other with their side edges in alignment, and the said side edges are then connected by apply-I ing thereto strips2 of flexible material (preferably relatively thin) likewise impervious to air. The said strips are also formed pref-y erably of rubber or rubberized fabric and are arranged to extend across the edges of the strips 1, l and part way over the sides there of and are adhesively secured'in place, either by cementing or vulcanizing. The strips thus-secured form practically flexible hinges between the edges of the strips 1 and 1"- lying on opposite sides of their juxtaposed faces. In methods ofl making collapsible valves heretofore pursued, the resultant article has been found liable todevelop a hair line leaky 'at the extremity of the slot due to the fact that such valves haveA been customarily formed by folding a 'sheet upon itself and with a rubber reinforcement as indicated at 5.
Having thus described my invention, what I claimI is:
1. .'Ihe herein described method of making collapsible valves which includes the steps of superposing two sheets of flexible material impervious to air, and securing. to the edges thereof in overlapping relation thereto stripsof flexible material likewise impervidus to air to form hinge-like connections between said edges. l
2. The herein described method of making collapsible valves which includes the steps of superposing two narrow sheets of rubber, and adhesively securing to O pPGsite edges thereof in overlapping relation-thereto strlps of thin sheetmaterial impervious to air.
3. In a collapsible valve a pair of juxtai pose sheets of material impervious to air having alined edges, and strips of flexible material impervious to air overlapping said' edges.
4. In a collapsible valve` a pair of .rubber sheets having flat facesin contact and peralined edges and adhesively secured theretoand forming hinge connections between saidl pendicular alined edges, and rubber strips extending across said edges and overlapping the outer sides of the sheets and adhesively secured thereto. l
In testimony whereof I affix my signature.
WM. W. MACDONALD.
