UNITD STATES ATENT OFFICE.
HENRY P. KRAFT, 0F RIDGEWOOD, NEVT JERSEY; EDGAR J. PHILLIPS AND EARL A. DAB/R EXECUTORS OF SAID HENRY P. KRAFT, DECEASED.
DUSTCAP.
Application filed December 19, 1919.
To all whom it may concern.-
Be it lmown that I, HENRY P. KRAFT, a citizen of the United States of America, residing in Ridgewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Dustcaps, of which the following is a specification.
This invention relates to dust caps or the like, and aims to provide certain improvements therein.
The invention is particularly directed to that form of cap which is shown in a prior patent issued to me, No. 1,315,778, wherein the cap portion is formed in a plurality of longitudinally arranged parts. This type of cap marks a very considerable advance in the art, the cap being light and strong and exceedingly cheap to manufacture. I have found, however, that I can still furthercheapen the structure by facilitating the operations of manufacture and assembly.
The type of cap illustrated in said patent is adapted to be secured to a tire valve or similar structure and in some cases the means of securing comprises screw-threads usually formed directly at the bottom of the cap, and either adapted to directly engage the threads of the valve, as is specifically illustrated in said patent, or to engage a clamping means having a corresponding thread.
In the construction of the cap of the patent such threads are usually stamped in the separate longitudinal sections or parts of the cap, and during the operation of assem bly the threads are matched to form a con-- tinnous thread. This operation requires a careful assembly. According to the present invention I adhere to the two-part'structure, but I form the screw-thread in a col lar, the upper edge of which is connected to the two-part cap. This collar is preferably seamless and the thread may be formed in it either by rolling or otherwise. The upper edge of the collar is fastened to the lower edge of the cap portion, so that it forms continuation of it. The thread thus formed may either directly engage the valve stem, or other screw-threaded part, or may provide the threads for a clamping device. By
the use of such construction any precise Serial No. 346,018.
are in precise alinement at their lower edges. At the same time a continuous and unbroken thread is assured.
In the drawings, wherein I have shown several embodiments of the invention,
Figure 1 is an elevation of one form of cap.
Fig. 2 is section.
Fig. 3 is a view similar to Fig. 1 partly in section showing the cap applied, the view being taken at right angles to Fig. 2.
Fig. 4 is a section of Fig. 2.
Fig. 5 is an underside view of Fig. 2.
Fig. 6 is a side elevation partly in section of another form of the cap.
Fig. 7 is a perspective view of the cap of Fig. 1 with the wingnuts omitted.
In Figs. 1 to 5 of the drawing'I have shown the invention as appliedto a nick an enlarged elevation, partly in detachable cap of the type illustratet in my prior patent No.- 1,501,350. In these figures A indicates the cap as a whole which is shown as comprising a cap portion B and a foot portion C. The cap portion is shown as being formed of two longitudinal sections D and E (Fig. 3), and an extension F connected to the sections D and E at the lower end of the latter.
The sections D and E are best formed with overlapping flanges, as shown in said patent and as illustrated in Fig. 4. The continuation F is formed as a circular band or sleeve which is best constructed from a sheet metal cup, the bottom of which is cut out, as shown at G, and the walls of which are threaded, as shown at H. Such threads are preferably rolled into the sleeve, so that they are exterior as well as interior, but in the present instance the interior threads are alone utilized. The lower edges of the sections D and E are preferably flanged outwardly and then inwardly, as shown at I, and the sleeve has a corresponding flange J which overlies the flange I. The flange I rests upon an enlarged portion J just below the flange J The flan e J is preferably recessed, as shown at K to fitthe longitudinal flanges L L of the cap portion and also to fit the stiffening beads M M formed longitudinally in the walls of the sections D and E. This construction produces a nonrotative connection between the parts and also prevents the sleeve F from slipping upwardly along the sections D and E. Any other suitable form of conneetion array be adopted, which suitable.
In the construction shown in Figs. 1 to the 0 1 pe tier C a r nge in ernally of the p p i i s instea 9. ext na ly, illustrated in my prior Patent No. 1,501,350. The foot portion is provided with flats which engage the flats of the tire valve, so that as the cap is rotated to the right (tor instance) the cap portion B is caused to new downwardly with e ati n to th on par ies andi ring c am-p r ng 9 into contact with tliebevelled tace P formed .0 1 th can porti n, hu con r c ing the -P r ng 0 or-i qi aalen cirmuni rentially c us g it to i d he va stem or casin as shown in Fig. 3. The
- bevel ed ace is very ena nie tly for e without reference to any matching.
Inthe constrnction illustratedwvhen the bottom is cut out, of the cup which forms the sleeve F, a flange Q, is preferably left, which forms astop for the loot portion C, so that the latter cannot be screwed out of the cap portion.
The operation of applying and removing the cap from the tire valve or the like is similar to that described in the aforesaid application, it being only necessary to. slip the cap over the valve stem or casing and rotate" the cap portion a short distance, whereupon the foot portion travels upward:
ly, and contracts the ring 0 by moving it against the bevelled face P. As soon as the clamp ring has made a contact with the valve stem, so that it cannot slip alongthe latter, the further movement of the cap portion tends to bring the cap portion firmly against the rim nut It or the wheel felloe.
In the construgtion shownfin Figs. 1 to 5 I have illustrated the cap as. being provided with wings S S which are best formed on .a sleeve T, the latter being recessed to fi lover the flanges of the cap portion, and being pressed into place. Such a construcion PIQYidQfi a winge car pa of a y assembly .e the wing d the r- In Fig. 6 I have shown the invention as applied to an ordinary screw cap, the sleeve between the cap sections, and practically does away with any possibility 10f separation under unusual or inordinate strains.
WVhile I have shown and described theinvention as applied to several forms of caps, it will be nnderstood that it is applicable .to any device which requires to beclamped into position, as for instance, pump couplings ,or the like.
It will also be understood that I do not wish to be limited to the construction herein shown and described, since various changes maybe made therein without departing from the spirit of the invention.
1. A dust cap or the like, comprising a plurality of longitudinal sections connected together along their longitudinal edges and forming outwardly extending flanges, and
a winged sleeve having notches engaging said flanges, the sleeve being fixedly carried by the cap.
2. A dust cap or the like, comprising a plurality of longitudinal sections connected together by longitudinal outside flanges, each section having at its lower end an outwardly extending flange, and a circular section having. a flange notched to engage said outsidefiangesand engaging over said outwardly extending flanges.
In witness whereof, I have hereunto signed my name.
HENRY l3. KRAFT.
