Application filed January 15, 1928. Serial No, 612,779.

To aZZ whom it may concern Be it known that I, JOHN J. MEYER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Insertable Joint, of which the following is afnll, clear, and exact description.

This invention relates to insertable joints for soil pipes and the like and has for an object to provide an improved construction wherein a new section may be inserted without disturbing the lower part of the soil pipe or the upper part and at the same time present a proper support for the superimposed sections of pipe.

Another object of the invention is to provide a joint for soil pipes wherein a specially constructed pipe section and hub are used together with certain other parts for presenting a proper hub and also a proper support for the superimposed pipe sections.

A still further objector the invention is to provide an insertable joint wherein co-acting threaded members are used in the hub of the joint to present a firm support for the superimposed pipe sections.

A further object is to provide an insertable joint including the subject matter divided from my co-pending application, Serial No. 480,295.

In the accompanying drawing- Figure 1 is a side view of part of a soil pipe as it appears when in place in a building, certain parts being broken away for better disclosing the invention as applied to the 'soil pipe.

Fi ure 2 is an enlarged sectional view showing the detail construction of the upper end of the joint embodying the invention.

Figure 3 is aview ofthe lower end of the superimposed soil pipe with a supporting cap associated therewith; 7

Figure 4 is a top plan view of a supporting cap or nipple disclosing a modified construction to that illustrated in Figures 1 and 2.

Figure 5 is a view similar to Figure 2 but showing a modified form of the invention wherein the hub is made integral with the pipe section. Referring to the accompanying drawing by numerals, 1 and 2 indicate the floors of a building through which a soil pipe 3 extends.

The soil pipe 3 is provided with any desired number ot-sections including a branch con INSERTABLE JOINT. i 1 g 2::

nection 4. In order to insert the branch connection 4, one of the sections of the pipe 8 must be broken and removed and then in order to provide a continuous soil pipe with a proper support for the upper sections, a specially constructed insertable joint 5 is provided. The joint 5 is formed with a pipe section 6 having an outturned upper end 7 ,Which is really a flange, said flange being threaded on the outer edge for receiving the threads on the lower end of the hub 8 which hub is internally threaded at the lower end. Arrangedinthehub 8 is an internally threaded sleeve 9 preferably held in place by a suitable set screw 10, said sleeve preferably rest ing on the flange 7 and its internal threads co-acting with the external threads on the cap 11, which cap is provided with an inwardly extending shoulder or flange 12. The shoulder or flange 12 acts as a support for the superimposed pipe sections and is engaged by the lower end of the lowermost superimposed pipe section 13. The cap 11 is preferably locked to the pipe section 13 by any suitable number of set screws 14. It will be noted that the sleeve 9 falls short of the top of the bell 8 and the cap 11 is positioned at any desired point along the sleeve 9 according to the position of the lowerend of section13. However, the upper end of the cap 11 and the sleeve 9 form an artificial bottom for the bell 8 for receiving packing to make the joint water and gas tight.

If desired, the bell 8 could be made integral, as for instance, the bell '8 shown in Figure 5. Aside from the fact that the bell 8' is made integral and the bell 8 is made separate and threaded into position, the structure shown in Figures 2 and 5 is identical so that the same reference numerals will apply to both.

In Figure 4, a slightly modified construction of cap is shown which is divided in half and normally held in position by the clamping screws 15. Instead of using the cap 11, a cap 11' as shown in Figure 4 might be used and when this is the case, the set screws 14 are dispensed with whereby the capmay be clamped rigidly to the section 13 without the use of set screws.

According to the present invention, an

improved structure has been provided which presents an easily insertable joint and one which is strong as well as water and gas tight. The section 6 forming part of the present invention, is of the usual construe tion at the lower end but the upper end is formed with a flare or flange 7 threaded to receive the bell 8 after the part have been properly aligned. While the section 6 is be- 1ng inserted, the section 13 and superimposed sections are temporarily supported by any suitable means, as for instance, wires, and the cap 11 is placed in position and clamped to the section 13 by the set screws 14:. The hub 8 is then forced over the section 13 and finally the sleeve 9 is threaded onto the cap 11 until the lower endis approximately flush with the lower end of the cap. The section 6 is then placedin position and swung into alignment with the section 13, after which the sleeve 9 is screwed downwardly until it is press ing against the upper surface of the flange 7 so as to co -act wit-h the cap 11 and provide a permanent and proper support for the section 13 and associated parts. After the parts have been thus adjusted, the bell 8 is screwed down to the position shown in Figure 1 and said screw 10 tightened. The temporary wires or other supports for the section 13 and superimposed sections are then removed and a proper packing or filling of any desired kind is provided in the upper part of the bell, the upper ends of the cap 11 and sleeve 9 acting as a false bottom for the hub. After the packing has been placed in position, the job is complete and the entire soil pipe is as strong and effective as it was before the joint was inserted.

In Figure 3, will be seen how a composition pipe or a pipe having comparatively thin walls is taken care of. In the structure shown in Figures 2 and 5, the walls of the pipe 3 are comparatively heavy, said pipe being made of cast iron or other cast metal. In the structure shown in Figure 3, the pipe 3 has the same here but the walls are thinner and, consequently, the set screws 14: act to properly center the pipe in the cap 11 as well as temporarily clamp the cap in place.

It is understood that crevices or gaps between pipe section 13 and cap 11, caused by the pipe section not being uniformly thick in wall or uniformly round may be filled with any desired filler, such as metal or cement in addition to the set screws or as a substitute therefor.

What I claim is i 1. An insertable joint for soil pipes, comprising a tubular adjustable supporting gap spacer consisting of two parts adapted to be inserted in a gap in a soil pipe line between the horizontal face of a pipe end when in vertical position and the horizontal face of an upper pipe end to form a support and provlde a waterway, a hub of the portable type confining said gap spacer and the two abutting pipeline ends, and a'filler joint between the upper pipe end. and-the hub, one

neeaeai end of said gap spacer to rest by gravity upon the pipe face independent of the hub and the other end of said spacer to abut and support the upper pipe end, said two parts of said spacer threaded into each other by male and female running threads whereby one part may be screwed into the other to cause extension or contraction lengthwise to correspond to the length of the gap and to permit insertion.

2. An insertable joint for soil pipes and the like, comprising two members adapted to be inserted into a gap between two opposite pipe ends of a pipe line in tubular alinement therewith from a direction at right angles to said pipe line, a removable hub adapted to confine said two members and said pipe ends, said two members be ing threaded on each other and capable of being extended or contracted lengthwise independent of said hub and pipe, one mem ber adapted to rest by gravity on the lower pipe end or on the plane thereof when in vertical position and the other member to abut and support the upper pipe end and the line thereabove.

3. In combination with a vertical soil pipe line and the like having a lower pipe section having a flange at one end, a tubular sleeve resting by gravity on top of said flange, a cap threaded onto said sleeve adapted to be screwed upon said sleeve to form a support and waterway for a pipe line thereabove, a hub surrounding the outer walls of said pipe line adjacent the ends of said sleeve and cap, a lead calked filler joint above the cap between the hub and the lower end of said pipe line, said sleeve and cap being independent of said hub and contained within the hub, said sleeve and cap threaded on each other being capable of expansion and contraction lengthwise by reason of their running threads independent of the hub and pipes and capable of being inserted into the gap between the two pipe sections from a lateral or transverse direction in alinement with the soil pipe line and adjusted in length to correspond to the gap.

4. In combination with a vertical soil pipe line or the like, having an insertable joint of the type having an exterior flange and a removable hub on said flange as one of its pipe line sections and a gap within said hub between the top of said flange and the end of a pipe line above, said hub being adapted for a filler joint around the upper pipe end, a gap spacer comprising two parts adapted to be inserted on top of said flange into said gap from a lateral direction when said spacer is contracted in length and to support the upper pipe in tubular alignment when extended, said spacer parts being threaded one upon the other and capable of sinking one into the other entirely by means of male running threads on one part and female running threads on the other part, said parts being free of the removable hub to permit independent movement and lateral insertion.

5. An insertable joint for soil pipes and the like, comprising two members adapted to be inserted into a gap between two opposite pipe ends of a pipe line in tubular alignment therewith from a direction at right angles to said pipe line, a removable hub adapted to confine said two members and said pipe ends, said two members being threaded on each other and capable of being extended or contracted lengthwise independent of said hub and pipe, one member adapted to rest by gravity on the lower pipe end when in vertical position and the other member to abut and support the upper pipe end and the line thereabove, said members being adapted that when positioned on lower and upper pipes the lower member may be rotated on the threads of the upper member and contracted to provide clearance below said members to permitthe removal or replacing of the pipe section below the members, one of said two members being capable of being submerged into the other member to obtain a minimum of contraction in length to facilitate insertion, said two members having exterior diameters considerably less than the interior diameter of said hub to allow independent movement of hub and members, said two members being adapted to exert pressure on said upper pipe end by rotating the member resting on said lower pipe end on'the upper member to cause extension and support.

6. A joint for soil pipes, comprising a section of pipe provided with a flange and a comparatively large hub, an internally threaded sleeve resting loosely by gravity on said flange within the hub, said sleeve being independent of the vertical sides of said hub when the soil pipe and hub are in vertical position and terminating within said hub, an externally threaded cap formed with a supporting flange, said cap being adapted to be supported by the threads on said sleeve, and means for rigidly clamping said cap to a. soil pipe section whereby it acts as a joint and a support for said section.
