M. C. SCHWEINERT COMBINED DUST GAP AND VALVE CAP Original Filed Oct. 19, 1921 Imke/Zim Patented Feb. 147, 1931 MAXIMILIAN CHARLES SGHWEINERT, OF NEW YORK, N.' Y.,.JSSIGiNORl TO. A. y
SCHRADERS SON', INCORPORATED, 0F BROOKLYN, NEW YORK, A CORPORA- TION OF NEW YORK v COMBINED DUST CAP AND vAnvE cnr` Application led October 19, 1921, Serial This invention relates to a combined dust cap and valve cap, and aims to provide certain improvements therein. y
In an application filed on even date herewith, I have described and claimed Aa combined dust cap and valve cap in which the parts have interengaging frictional means, by which, when the valve cap is screwed n the valve casing, the dust cap is held in place 0 thereon, and in which the dust cap may be removed bodily from the valve and valve cap if desired, or in which the valve cap may be unscrewed or replaced by manipulation of the dust cap.
rlhe present invention relates to a modification of this structure in which a different type of frictional device is employed. Ac-
cor-ding to the present invention, the valve cap 1s provided with a series of spring arms,
which, in the preferred form, are constructed two, thus providing the capacity in the dust cap of screwing on or removing the valve In the drawings wherein I have illustrated one form of the invention:
Figure 1 is an elevation of the combined structure.
Fig. 2 is a diametrical section of the dust cap disclosing the valve cap in elevation.
Fig. 3 is a cross-section on the line 3-3 in Fig. l, the valve cap being omitted.
Fig. 4 is a cross-section on the line 4-4 in Fig. 2.
Fig. 5 is a diametrical section of the valve cap.
Referring to the drawings, let A indicate the dust cap which, in Fig. 2, is shown as api plied to a valve casing B, and bearing against the ordinary rim nut C. Within the dust cap is arranged the valve cap D, which is shown as mainly of the usual construction having a No. 508,71191. `Renewed February 1, 1924:/
ing split at various parts, as indicated at F,
to form tongues which are preferably bent upwardly and outwardly, thus providing a series of arms having suicient springiness to form an adequate frictional engagement with the dust cap.
Fig. Sis a cross-section ofthe dust cap which I prefer to employ, although the latter. may be variously constructed. In this construction the series of grooves G are formed on the interior of the cap. Preferably, the arms E of the valve cap are equal in number to the grooves, and are so formed that the adjacent portions of the arms extend into the grooves as shown at H in Fig. 4.. By this means a non-rotative engagement between the two caps is formed which, nevertheless, permits the relative longitudinal movement of the parts. Y.
In operation if it is desired to insert the valve cap, this may be done by manipulating the dust cap, as may also the operation of applying the valveV cap. The construction, however, permits the bodily removal of the dust cap while the valve cap is in place, so that the latter may be unscrewed and used as a tool for removing or applying the valve inside parts.
The construction of this invention is superior to constructions in which the two parts are inseparably connected since the present invention permits the use of the valve cap as a manipulating tool for the valve insides. In constructions wherein the manipulating tool is on the dust cap, too great leverage is present for the necessarily small parts constituting such insides,- and there is danger of breakage or distortion.
While I have shown and described one form of the invention, it is understood that I do not wish to be limited thereto, as various changes may be made therein Without departing from the spirit of the invention.
What I claim is:
1. A valve cap having a body portion With a circumferential continuous part enclosing a packing gasket, and a series of spring arms adapted to engage the interior of a dust cap.
2. A valve cap having a body portion having a circumferential continuous part enclosing a packing gasket and a part slit to provide a series of spring arms Which are turned outwardly to engage the interior of a dust cap.
3. A valve cap having its body slit to provide a series of spring arms which are turned outwardly and upwardly.
4l. A valve stem cap comprising a hollow stamping closed at one end, the other end of the stamping being reversely folded and provided With a seri-es of parallel slits affording a plurality of angularly related spring tongues.
In Witness whereof, l have hereunto signed my name.
MAXMILIAN CHARLES SCHWEINERT.
