VALVE FOR PNEUMATIC TUBES, 84C.
SPECIFICATION forming part of Letters Patent No. 584,478, dated J une 15, 1897. Application filed April 24, 1896. Serial No. 588,8 72. (No model.)
.To all when@ t may con/cern.'
Be it known that I, JOHN O. MACSPADDEN, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Valves for Pneumatic Tubes and other Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to valves for pneumatic or air-inflated tires and other inflatable devices, such as foot-balls, punching-bags, and the like; and it has for its general object to provide a simple and effective non-return or check valve, which is more especially designed as a repair-valve -that is to say, is designed to be quickly and easily connected to the outside of and used in conjunction with air-tubes at present in use when it is necessary to equip the same with a new valve.
The invention also contemplates the application of the improved valve to the air-tubes at the time of manufacture, since the cheapness of and the ease and facility with which the valves may be applied will very materially lessen the cost of the completed air-tube.
The invention will be fully understood from tle following description and claims when taken in conjunction with the accompanying drawings, in which- Figure l is a transverse section of the airtube of a bicycle-tire equipped with my improved valve. Fig. 2 is a section taken in the plane indicated by the line as of Fig. l with a portion of the air-tube cut away to better illustrate the valve and the base of the inflation-tube. Fig. 3 is a detail transverse section illustrating an air-tube embodying a modification. Fig. 4 is a section similar to Fig. 1, taken through the modiiied tube. Fig. 5 is a detail section taken in the plane indicated by line vof Fig. 4.. Figs. 6 and 7 are detail sections illustrating another modification, and Fig. S is a detail section of still another modification.
Referring by letter to said drawings, and more particularly to Figs. l and 2 thereof, A indicates the felly of a bicycle-wheel.
B indicates the air-tube of the tire, which may or may not be i-nclosed in a cover, as desired, and C indicates the unobstructed airinlation tube, which is preferably equipped with a cap a, as shown, to prevent the entry of dust to the valve and valve-seat` presently described. This inflation-tube Chas an outer casing a of metal and an inner portion b of rubber and cloth, and this portion l) merges' at its inner end into a base c, which is designed and'adapted to be connected to the outside of the air-tube by rubber cement or other suitable means, as will be presently described, and is preferably provided on its inner side with the piece of rubber f, which surrounds the aperture g in said base and is designed and adapted to serve as a valve-seat, asillustrated in Figs. l and 2 of the drawings.
D indicates the non-return or check valve. This valve D may be formed of silk, rubber, or any fabric or other material that will resist the passage of air; but I prefer to form it of a thin piece of rubber, which, on account of its resiliency, is superior to any other material, as will be appreciated. The said valve D preferably comprises a circular body h, which is designed to rest over the aperture g in the base of the inflation-tube O, and the diametrically opposite arms t', which are connected to the inner side of the inflation-tube base c by rubber cement or the like, as illustrated in Figs. l and 2.
' Prior to the connection of the base of the inflation-tube C to the outer side of the air or iniiatable tube B the said tube B is provided with two slits E, as shown. The said base c of the inflation-tube O is then arranged upon the outside of the tube B and so that the" valve D rests over the slits E in said tube B. The portion c of the inflation-tube base c, which may be connected to the outer side of said base byrubber cement, as shown, or may be formed integral with the same, is then connected by rubber cement or other suitable means to t-he outer side of the air-tube B in an air-tight manner, and when the cement` IOO h of the inflation-tube base c and the outer side of the tube B, and will then pass between the valve D and the outer side'of the tube B to and through the slits E into the interior of the tube B. When the air seeks to escape from the tube B, it will, as will be readily observed, exert a pressure against the inner side of the valve D and will press and hold said valve securely against its seat and will thereby effectively prevent its escape through the tube C.
In practice my improvements will be prepared ready to beattached to a tire-tube, and consequently when a tube is to be equipped with a new valve allthat is necessary is to slit the tube, as indicated by E, and then connect the base of the inflation-tube c in the manner described, when the valve will be ready for use. This, as will be observed, may be very quickly and easily done and at small cost, and when the valve has been properly connected it will serve efficiently as long as nthe air-tube itself remains good, and will not be liable to be casually disconnected from the tube B.
In Fig. 3 of the drawingsI have illustrated a modification in which the base c of the inflation-tube C is formed in one piece and integral with the rubber inflation-tube portion,
andr the tube IB' is provided with a circular opening E/ in lieu of the slits E before described. Otherwise this construction is the sameA as that before described, the base c be- Aagainst its seat.
In Figs. 4 and 5 is shown a modification in which grooves t are provided in the inner side of the inflation-tube base o2 to receive the arms t' of valve D, so as to enable said arms to rest flush with the inner side of the base. Otherwise this construction is the same and operates in the same manner as that shown in Fig. 3.
In Figs. 6 and 7 of the drawings I have illustrated a. construction in which a portion of the infiatable tube B2 is made to serve as a.
check or non-return valve to prevent the escape of compressed air from the tube. This is done by slitting the tube B2, as indicated by E2, and thus forming the valve D'. In
conjunction with the tube B2, I employ an inflation-tube C, having a base c', which is connected to the outer side of the tube B2 and is arranged so that the air-induction opening of the tube C/ will rest over the center of the valve or valve portion D. In using this construction When the air is forced by the inflating device through,the tube C the valve D' will be forced and held from its seat, and in consequence the air will pass to and through the slits E2 into the interior of the tube B2; Vhen the inflating device is removed from the tube OQ it Will be seen that the air within the tube B2 will exert a pressure against the inner side of the valve D and will hold it securely against its seat and thereby effectually prevent the escape of air.
In Fig. 8 is shown a construction which is similar in all respects to that shown in Figs. l and 2, with the exception that a series of apertures E2' are employed in lieu of the slits E.
Having described my invention, what I claim isq l. As an improved article of manufacture, a repair-valve. comprising an inflation-tube having an. inner portion b, of rubber provided with exterior threads, and an o utercasing a, of metal receiving the portion h, and having interior threads engaging the threads of the portion b, the base c, formed integral with the rubber portion I), and adapted to be connected by rubber cement or the like to the outside of an iniiatable device, a check-valve of thin rubber or similar material connected to the inner side of the base, and a capconnected by threads to the metallic portion of the innation-tube, substantially as. specified.
2. The combination of the inflatable tube or other inflatable device having an opening, an inflation-tube having the base arranged on the outer side of the infiatable tube over the opening therein and secured to said outer side of the tube by rubber cement or the like, and the check or non-return valve of thin rubber or similar material secured to the inner side of the base of the inflation-tube and interposed between said base and the inflatable device and adapted to open to permit air to pass fromy the inflation-tube to the interior of the inflatable tube and also adapted to check the escape of such air from theinflatable tube, substantially as specified.
3. The combination of the inflatable tube or other inatable device having an opening, a repair-valve comprising an inflation-tube having the base connected by rubber cement or the like to the outer side of the inflatable device, and the fiat check or non-return valve of sheet-rubber or other suitable material connected to the inner side of the inflation-tube base and adapted to check the escape of air through said tube, substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses.
JNO. C. MACSPADDEN.
