5. F. JACKES PIPE JOINT Filed Feb. 3, 1930 Patented Apr. 19, 1932 UNITED STATES 2' m ga STANLEY F. JACKES, OF ST. LOUIS, MISSOURI, ASSIGNOR TO JACKES-EVANS MANU- FACTURING COMPANY, OF ST. LOUIS, MISSOURI-A CORPORATION OF MISSOURI "stresses PIPE JOINT Application filed February 3, 1930. Serial No. 425,499.
Thisinvention relates to joints for flues and the like, and with regard to certain more specific features to pipe joints for enameled stove pipe.
Among the several ects of the invention may be noted the provision of means for adapting improved enameled stove pipe to more effective use; the provision of means of the class described which re-introduces the resiliency at the joints which is lost by enameling the pipe; and the provision of means of the class described which shall be economical to manufacture, easily applicable, and effective in operation. Other objects will be in part obvious and in part pointed out hereinafter.
The invention accordingly comprises the elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structure hereinafter described, and the scope of the application of which will be indicated in the following claims.
In the accompanying drawings, in which is illustrated one of various possible embodiments of the invention,
Fig. 1 is a side elevation of two lengths of pipe, made and joined according to the present invention, certain portions being broken away for clarity;
Fig. 2 is an enlarged cross section showing certain features of the invention; and,
Fig. 3 is a perspective view of a pliable band or collar.
Similar reference characters indicate corresponding parts throughout the several views of the drawings.
Referring now more particularly to Fig. 1, there is illustrated at numeral 1, a length of *pipe joined to a length of pipe 3 at a joint 5.
As illustrated in Fig. 2, the pipe of each section comprises a sheet iron body 7 which is relatively thin and which will yield when strained. Because of this property, the ordinary sections of stove pipe may be readily joined by forcing a tapered and corrugated portion such as is illustrated at numeral 9, into a receiving portion 11 in the juxtaposed pipe section 3, without setting up local and without leaving openings through which smoke may leak out or cold air leak in. That is to say, the outline of the receiving portion 11 conforms itself to that of the entering portion 9, regardless of irregularities, provided the ordinary sheet iron pipe is used. The conformation may also be vice versa to that above described, or mutual conformation may be effected between said parts 9 and 11.
It. isthe object of the present invention to overcome certain dificulties which have arisen when this type of tapered joint is attempted to be made between sections of improved enameled pipe. Referring to Fig. 2, it will be seen that the improved pipe referred to comprises sheet iron 7 externally covered with a coating of enamel 13 and internally with a round coatin 15 of the same substance. The enamel is put on the pipe for the purpose of improving its appearance and wearing qualities. The enamel resists corrosion and other forms of deterioration. It will be appreciated that enamels are vitrified substances and as a result have a hard or flnty texture. Thus, in improving the ap pearance and wearing qualities of the pipes by enamelling the same, there is introduced the difficulty that the resiliency or pliability of the original sheet iron body 7 is reduced. That is to say, the pipe sections are stiffer. As a result, when the portions 9 and 11 are telescoped for making a joint section 5, said parts 9 and 11 do not conform to one another so well, and openings are left through which air leaks in or smoke leaks out. F urthermore, the endwise pressure used in bringing the sections 1 and 3 together, sets up local strains at the few points of contact which do occur, thus tending to chip off the enamel.
In order to retain the advantages of enameled pipe and effect a proper joint, I provide a resilient or pliable and relatively soft sealing collar, such as shown in Fig. 3. This device comprises a ring 17 having a width adapted to cover a substantial area of the tapered and corrugated end 9 of the section 1. The collar 17 is preferably formed in a truncated conical shape so that it may be readily applied over the tapered portion 9.
It is stopped by the stop bead 19 preferably 1 rolled into the pipe above said portion 9. It may not actually reach contact with said head 19, but be stopped by the tapered conformations.
It Will be seen that inasmuch as the tapered portion 9 is corrugated, the separable, tapering collar 17, when slipped over said portion 9 is adapted to be frictionally held thereon. This holding action is enhanced by the fact that the taper construction is used. Furthermore, the tapered construction permits easy application of said collar 17, as well as permitting easy entry of said section 1 into the section 3. In many cases it is desirable to glue the collar 17 to the member 9 by a fireproof glue such as sodium silicate.
After the collar 17 is applied over the portion 9, said portion 9 with the collar 17 there on may be pushed into the receiving portion 11 of the juxtaposed section 8. When the sections 1 and 3 are pushed together the resilient or pliable collar 17 receives the local pressure and transmits it to a greater area than would be otherwise possible without the collar 17, thus preventing enamel chipping. At the same time, the collar 17 seals the said joint against leakage, either in or out.
The collar 17 is made of a resilient, pliable material which is also fireproof. An example of one of the preferable materials is asbestos sheet. The collar 17 is made preferably by cutting a strip and winding it into a conical form and gluing it at a joint such as indicated at numeral 21. The substance which may be used as a glue should also be fireproof, such as sodium silicate, for example. It is to be understood that other forms of fastening may be used, such as small countersunk rivets or the like.
It will be seen that one of the advantages of the present invention comprises making the packing material in the joint 5 a separable element which may be separately manufactured, applied to the entering portion 9 of section 1 and then the whole applied to the receiving portion 11. By this means, a tedi-' ous and expensive packing operation is eliminated when the pipe is assembled.
In view of the above. it will be seen that the several objects of the invention are achieved and other advantageous results attained.
As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
I claim:
1. A pipe comprising a plurality of sections formed from enameled sheet iron, one of which includes a tapered entering portion and the other of which includes a receiving portion for said entering portion and a pliable collar formed from fire resisting material adapted to be mounted on said entering portion to be carried into contact with said receiving portion when the latter receives said entering portion.
2. A pipe comprising an enamel section, a taperedand corrugated entering portion on said section, a tapered, pliable collar adapted to be applied to said corrugated portion, a second section of pipe having a receiving portion and adapted to eXteriorly engage said collar and said entering portion, said collar being adapted to provide a resilient holding and sealing medium between said sections, said collar being formed from asbestos.
3. A pipe comprising telescoping sections of enameled sheet iron pipe, a seal between said sect-ions of the telescoping portions comprising an asbestos paper band, a joint in said band and means for fastening said joint comprising sodium silicate.
In testimony whereof, I have signed my name to this specification this 30th day of.
January, 1930.
STANLEY F. JACKES.
