PIPE CLOSURE DEVICE Filed Nov. 17. 1950 ...n L f@ Patented Jan. 10, 1933 UNTEE STATES PATENT OFFICE JACOB H. HIB-SCH, F CHICAGO, ILLINOIS, ASSIGNO TO AUTOMATIC BURN'ER CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION' OF ILLINOIS PIPE-crescita DEVICE Application filed November 17, 1930. Serial No. 496,297.
My invention relates more particularly to closure devices tor closing the upper threaded extremities or the liller-pipes ot oil tanks buried in the ground and forming partsmore particularly ot oil-burner installations. These ller pipes in accordance with common practice extend at their upper iiller openings above the ground a considerable distance, usually trom six to eight` inches, to
avoid the possibility of water flowing into these pipes, these pipes in the case ot house installations commonly being located in grass-plots and are capped by a plain cap protectingonly the top thereof.
33 My object is to provide a closure device tor the upwardly projecting end ot such a fillerpipe having a portion surrounding said illerpipe and depending from the Zone of screw connection substantially to the ground line.
,i9 Referring to the accompanying drawing:
Figure l is a view in elevation of a closure device embodying my invention and showing it in position ot use; andl Figure 2, a vertical sectional view oi the -5 structure of Fig. l the section being taken normal to the joint between the two sections forming the body ot the closure device.
In the arrangement shown, the iiller pipe of an oil-storage tank (not shown) is repre- 3'5 sented at 3, this pipe in practice rising from the oil tank which would be buried in the ground indicated at e, and extending upwardly an appreciable distance, say about six or eight inches, above the level ot the ground,y
'5 as for example a grass plot adjacent the house equipped with oil-burner apparatus supplied with oil from the tank, the upper extremity ot' the pipe 3 being shown as externally I tires-ded as represented at 5.
o In accordance with my invention I provide as a removable and replaceable closure for the upper end ot the pipe 3, a closure device 6. rllhe closure device 6 which may be provided of any suitable form to accomplish the y CIL plied to the upper, open end ot the pipe 3, and above the lower open end is internally threaded at 7 when to be used with a pipe threaded as above stated and in accordance with common practice to adapt it to be screwed upon the threaded upper end 5 ot the pipe the closure device being providedl with a constricted portion or rib 8 in which the threads 7 are formed, the threads 7 in the closure device being preferably located above the low- 46u er open end oi' the device a distance substantially equal to the distance from the threaded iortion 5 of the pipe to the ground-level, whereby the closure device extends at its lower end close to, or against, the ground.
Preferably the body of the closure device is cast and made in two sections the joint therebetween being, represented at 9, these sections being secured together as by a screw lO which extends through one of the two sec- V7c tions and screws into a threaded socket l1 in a lug l2 on the other section, the internal contour of the main portion oi the body being substantially the same. kas the external contour ot such part. r`75 rlhe sectional construction of the closure device together with. the two means as at 5 and l0, to hold the sections in place on the .pipe 8, is important especiallyy since the de- Y vice is always exposed to the elements, and y"8C it the; threadsat 5 should rust or freeze, the' fastening l() could be removed or broken to enable separation ot the sections and hencev removal thereof without an unscrewing action. e5 1While I have illustrated and described the closure device as presentin(r a particular form, or shape, it will be readily understood that it may be provided ot any other unconventional form or shape withoutdeparting-9G from the spirit ot my invention.
TWhat l claim'as new, and desire to secure by Letters Patent, is:
l. A closure device tor the purpose set forth, formed of a hollow body consisting of longitudinally divided sections, means separably securing the sections together, said body having an opening in its lower end at which the body is adapted to be applied to the threaded end of a pipe to be capped and r provided internally with threads which reach short of the lower end of said device and at which the device screws upon the threaded end of the pipe whereby the device extends materially below the upper end of the pipe.
2. A closure device for the purpose set forth, formed of a hollow body consisting of longitudinally divided sections, means separably securing the sections together, said body being open at its lower end at which the body is adapted to be applied to the threaded end of the pipe, said body having an internally threaded constricted portion disposed above, and spaced from, the lower end of the body and at which the device screws upon the threaded end of the pipe, whereby the device extends materially below the upper end ofthe pipe, the closure device having a special exterior configuration serving dually for ornamentation `and to provide a gripping means to facilitate the application thereto and removal therefrom with respect to the filler pipe.
3. In combination with the upwardly extending threaded end portion of a filler-pipe for an oil tank positioned in the ground.y a closure device for said end portion comprising a hollow body consisting of longitudinally divided sections, means separably secur ing the sections together, said body containing an opening in its lower end at which the body is adapted to be applied to the threaded end of the pipe and provided internally with a threaded portion spaced from the lower eX- tremity of said device and at which the device is screwed upon the upper threaded end of said pipe with the lower end ofthe device extending materially below said threaded portion, the closure device having a special exterior configuration serving dually for ornamentation and to provide a gripping means to facilitate the application thereto and removal therefrom with respect to the filler pipe. y 4. In combination with the upwardly extending threaded portion of a iller-tube for a. tank positioned in the ground, a closure device for said end portion consisting of a hollow body, comprising longitudinally divided sections and open at its lower4 end whereby it may be applied over said end of the fillertube, said sections having an inwardly eX- tending rib reinforcingr the same and also provided with screw threads applied to the threaded end. of the iiller-tube, vsaid device having a portion depending below said rib and substantially to the ground, and fastening means securing the sections of the device together and located above said rib.
