cLosuR Filed Jan. 18, 1945 rmi/vir fastening means;
Patented Feb. 8, 1949 UNITED STATES PATENT OFFICE oLosURE Anthony F. ciarfeno, Albany, N. Y.
Application January 18, 194.5, Serial No. 573,403 ciaims. (o1. 1ste-$9)vv My invention relates to closures and particularly to improved closures for pipes and the like.
Traps in soil pipes, for example, are usually closed by an end ferrule which is calked into the bell end of the trap and which is internally threaded to receive a closure plug. When it is necessary to open the trap the plug must be removed but in most cases it is impossible to loosen the plug without breaking the ferrule. Filling pipes leading to oil or other storage tanks are closed either by an end plug orV cap and in many 4cases these are very difficult to remove. Furthermore, the threads thereon are fre- Vquently damaged making it impossible to use the part having the damaged thread. l
The general object of my invention is to provide a closure for pipes and the like which can be easily opened or removed and which will at all times provide a substantially air tight seal.
Another object is to provide a device of this char- I accomplish these objects by means oi the novel elements and the combinations and arrangements thereof described below and illustrated in the accompanying drawings in which- Fig. l isa vertical cross section of my devi-ce in a form adapted for application to the trap in a soil pipe;
Fig. 2 is a fragmentary elevation view, partially in section, showing the exterior fastening means of my closure;
Fig. 3 is a fragmentary top plan View of my device, partially in section, showing the exterior Fig. 4 is a fragmentary bottom view of th cover, partially in section;
Fig. 5 is a fragmentary top plan view, partially in section, of the tubular element shown in Fig. 1 with the cover removed;
Fig. 6 is a fragmentary elevation view partially in section and with portions broken away, of a trap showing my closure element therein;
Fig. '7 is a vertical cross section of a modified form of closure adapted for use on the threaded end of a pipe; and
Fig. 8 is a section of Fig. 7 in the plane 8 8.
Referring to the drawings- My device comprises a tubular element such as I, here illustrated as an end ferrule, which is provided at theY bottom with a peripheral ledge 2 adapting it to be secured in the bell 3 of a trap by means of calking 4. Instead of being interiorly threaded at the top, as in the case of end ferrules of the present type, the tubular element I adjacent the upper end thereof is provided with an inwardly projecting lug 5 having the bottom surface 5 thereof upwardly inclined toward-the axis of the element I. At the upper end, the walls of the element I are preferably thickened slightly as shown at 1 and the extreme end of the element is provided with an annular projection 8, the outside diameter of which is slightly less than the outside diameter of the element I at the top so as to provide a narrow annular shoulder ,9 on the outside of and below the projection 8. The cover IIJ for the end of the element I is preferably slightly crowned onthe top and is provided on the bottom with an annularrecess II adapted to receive the annular projection 8 on the element I with a gasket I2 positioned in the bottom of the recess. The cover, on the bottom, is also provided with a depending lug I3 adapted to underlie the lug 5 on the' element I and in spaced relation thereto when the cover is in place. A set screw i4 passes through a threaded hole in the lug I3 and sets against the inclined bottom of the lug 5. Thus by adjusting the set screw I4 the distance between the lugs 5 and llil may be varied and by properly adjusting the set screw Y I4 a firm air tightcontact is formed by pressure on the gasket I2.
The side Yof the element I, in a zone substantially diametrically opposed to the lug 5, is provided with a pair of circumferentially spaced ears I5, and the threaded member I6 is secured, between the Vears I5 by means of the pin Il.
The cover IE, in a zone substantially diametrically opposite the lug I3, is also providedv with a pair of outwardly-extending, spaced ears I8 adapted to receive the, threaded element IBtherebetween, and a wing nut IS cooperating with the threaded element I6 serves to clamp the cover tightly against the gasket I2,
In order to remove the cover it is merely necessary to loosen the wing nut I9 so that the threaded element I6 with the loose wing nut thereon may be swung outwardly on the pin I'I as a hinge whereupon the cover may be removed by tilting it or turning it. until the set screw I4 moves out of engagement with the lug 5. To replace it the cover is tilted and the lug I3 is pushed under the lug 5 until the end of the set screw I4
