CHARLES H. BELDEN, OF CLIFTON SPRINGS, NEW YORK, ASSIGNOR TO JUDD AND LELAND MANUFACTURING COMPANY, OF CLIFTON SPRINGS,
AIR-VALVE.
SPECIFICATION forming part of Letters Patent No. 767,098, dated August 9, 1904.
Application filed November 18,1903. SerialNo. 181,679. (No model-l To. (ZZZ whom it may concern:
Be it known that I, CHARLES H. BELDEN, of Clifton Springs, in the county of Ontario and State of New York, have invented a new and useful Improvement in Air-Valves, which im provement is fully set forth in the following specification and shown in the accompanying drawings.
My invention is an air-valve, designed for use in inflating air-inclosures generally, but more particularly for filling and inflating storage air-tanks for general use.
The invention comprises a hollow bodypiece with reduced threaded end to screw into a socket or other part connected with the air tank or inclosure. To the body-piece is attached coaxially a swivel-nipple to which to connect the hose loading "from the air-pump, the nipple being free to turn upon its axis independent of the holding body-piece. A check-valve is employed, partly Within the body-piece and partly in the nipple, to act against the latter, to form an air-tight joint in the matter of holding the compressed air 2 5 in the tank.
Other objects and advantages of the invenf tion will be brought out and made to appear in the following description, reference beinghad to the accompanying drawings, forming a part of this specification.
Figure 1 is a side elevation of my improved receiving air-valve and associated socket. Fig. 2 is a longitudinal axial section of the body of the device,showing the latter before the thin shell or wall of the nipplechamber is spun down to inclose the flange of the nipple, the latter appearing in elevation and the valve being omitted. Fig. 3 is a longiv tudinal axial section of the device, showing 4 the interior construction. Fig. 4: is a transverse section of the body-piece, taken on the dotted line 4 4: in Fig. 3. Fig. 5 is a side elevation oi the device with parts broken out and axially sectioned, showing the check-valve open. Fig. 6 is a transverse section of the nipple on the dotted line 6 6 in Fig. 3, further showing the annular air-space around the stem of the valve. Fig. 1 is drawn to a scale one-third that of the remaining figures.
In the drawings, A is the main part or body 5 of the device, it being cylindrical in form, with the part a of largest diameter knurled on its convex surface. The body A is formed with a reduced coaxial threaded part 6 to screw into a threaded socket or short tube B, a packing-ring c, of fibrous material, being interposed between the parts A and B. The body A is formed with a series of coaxial cavities c, It, '17, Z, and m, Fig. 2, in a line and together forming a continuous opening through said body-piece from end to end. These cavities are of different diameters and all cylindrical, except the cavity a, which is flaring or conical and connects the cavity or chamber is with the smaller chamber Z, as 5 shown. The first and largest cavity or nipplechamber 6 is surrounded by a thin cylindrical Wall or shell f, primarily made straight or truly longitudinal, as shown in Fig. 2, but subsequently bent inward, as shown in Figs. 7 1 and 3.
O is a cylindrical nipple for the device, formed with a head 10 for receiving and hold- 3 ing the hose E for the inf-lowing current of air, said nipple having aflange or ring (Z at its base. In constructing the device the flanged base of the nipple is inserted in the chamber 6 and seated against a shoulder it of the bodypiece A, the latter and the nipple being coaxial. The shoulder it constitutes the bottom of the cavity or chamber 0 and is adjacent to the cavity 7: and in a plane at right angles with the axis of the nipple. The nipple is provided with a ring 9, of yielding packing, adjacent to the flange (Z and. inserted. in the 5 cavity a, as stated, the projecting end of the thin shell f being bent or turned down upon the ring of packing by the process of spinning to inclose and firmly hold the base of the nipple, the spun part taking a conical form, 9 as shown, and while the joint between the nipple and the body A is air-tight the nipple may turn upon its axis in its seat in the body A, as by a swivel motion.
The nipple C is hollow, it having an enlarged chamber '11 extending upward from the base adjacent to the chamber A) of the body A. l/Vithin the chamber k of the body is placed a longitudinally-movable valve D,having a stem 11 extending into the chamber of the nipple, as shown. The main part 0 of the valve is usually made polygonal in form, preferably hexagonal, as shown in Figs. 3, 4, and 5, with sometimes a short rearward extension p into the minor chamber Z. The valve D seats at 9 against the base of the nipple, there being usually employed a ring s,of packing material, on the stem of the valve to form an air-tight joint against the end of the nipple when the valve is forced outward by the air-pressure within the tank.
The valve D is shown in its closed position against the nipple in Fig. 3 and in its open position apart from the nipple and against the large end of the conical side or wall of the flaring chamber 21 of the body A in Fig. 5.
The stem 11 of the valve D is made considerably less in diameter than that of the chamber z' in the nipple, leaving an annular space t around the stem, and when the valve is in its open position air forced by the pump into the nipple will flow inward along said annular space t into the chamber 70. When the valve D is forced open or to the bottom of the chamber by the inrushing air from the pump, the polygonal part 0 will rest against the large end of the conical wall of the chamber n, as stated, and as the part 0 is not circular it will not fit said conical wall all around; but openings a, Fig. 4, for the passage of the air Will be formed one at the inner end of each face of the part 0. The aim in constructing the device is to so form the adjacent parts that when the valve is against said conical wall it shall not form a close joint with the wall; but openings shall be left beneath it through which the forced air may flow out of the body A and through the part B into the tank.
Usually the tube B is passed through a wall or side F, Fig. 1, of the air-tank, there being placed a packing-ring w under the head of the tube within the tank, as shown. Without the tank is a similar ring 1 of packing, upon the tube and a metal washer z, the whole being pressed or held firmly together by a nut a, threaded upon the tube, as shown, the threaded part 60f the body-piece A being inserted in the projecting end of the tube, as previously stated.
The construction of this air-valve is such that it may be conveniently employed as a permanent terminal or tip for the india-rubber hose attached to and leading from the airpump, this being a common use for the device. Thus employed it may be readily applied to use by turning or screwing its projecting threaded end I) into a corresponding internally-tln'eaded socket or part connected with the tank or other inclosure to be inflated, the swivel nature of the nipple C admitting of thus turning the body of the air-valve with out twisting the hose.
