To all @akami/imag] concern.' i

.Be it known thatLJoHN A.Si iiNo1iRa citizen of ythe'United States, residing at Beach, in the county of Los Angeles and State of California, have invented new and useful lImprovements in Lead-Joint Runners, of which the following is a specification. l

It is the object of this .invention 'to provide a lead joint runner which includes a recessed annulus received upon the inner one of overlapping pipe sections,'so that packing may be received within said recess and against the end of the overlying pipe section in order to provide a .space adapted-*to ref ceive the lead.

It is a further object of the invention-to provide extremely simple but eflicient means for retaining the `recessed annulus in position and tov generally improve and simplify the construction ofthe lead joint runner so as to form an inexpensive and practical device.

The invention will be readily understood from the following description of the accompanying drawings, in which- Figure 1 is a longitudinal section through overlappingpipe sections showing the lead joint runner in operative position.

F ig, 2 is a longitudinal section on the line 2 2 of Fig. i.

Fig. 3 is a transverse section on the line 3 3 of Fig. 2.

Fig'. 4 is a detail section on the line 4-4 of Fig. 3.

Fig. 5 is a detail transverse section through a portion of the recessed annulus forming a part of the lead joint runner and showing the means of retaining the packing within the recess.

Fig. 6 is a similar view showing the overlapping ends of the packing within its recess.

The lead joint runner is illustrated as employed in connection with pipe sections 1 and 2 having a usual overlapping end joint which includes an enlarged end flange 3 upon one of the pipe sections, shown as the section 2, and received over the end of the other pipe section 1.

The lead joint runner includes an annulus 4 which is formed in two sections hinged together as shown at 5 and adapted to be received around pipe 1 just beyond flange 3. This annulus includes a base portion and a peripheral flange 6 so that an annulus is pi'ovidedfwhich is recesse toward flange 3.

A -secondannulus 7 is `mounted upon the flange 3 and includes lsections hinged together as shown atg8. This annulus fits snugly upon flange --3 so as to impinge against enlarged collar 9 formed at the end of said flange. j

"lhe two annuli are fixed `in. position upon pipe section land upon flange 3 respectively by providinglthe swinging meeting ends of the hinged sections of the respectiveannuli with radially projecting lugslO. Af'` loop 11 is received over the'lugsflO'of each-ofthe two annuli forming thelead joint runner, and these loopsare fixed to one ofv eachof the respective pairs of lugs as by `reversely bending said lugs as shown at 10EL in order to form bearings for the meeting ends of the members forming the loops. Clamping bolts 12 are threaded through the swinging ends of the loops, receivedvover lthe ,other d at'its side turned lug of each of the pairs of lugs 10,:soas to of the hinged

sections forming annuli

4 and 7 In order to provide a space for the pouring of the lead, an opening 13 is provided in flange 6 at the ends of the hinged sections forming the annulus 4.

The

annuli

4 and 7 are clamped to one another by providing radial earsY 15 Yupon annulus 7 and receiving bolts 16 through said ears with nuts 17 upon the ends of said bolts for securing the same in position. The opposite ends of the bolts extend over annulus 4 with their end portions inwardly bentl at such an angle that the extreme ends 18 of the bolts will impinge against the base of annulus 4 adjacent pipe section 1. It will thus be seen that by tightening nuts 17, the l I two annuli forming the lead joint runner may be drawn toward one .another with the pressure of said clamping means received against the base of annulus 4 at the pipe section l and thereby in alineinent with the lead joint. L In using the improved lead joint runner, the space within recessed annulus4 between the base of the same and the end of the overlying flange of pipe section 2, is filled with' a suitable packing in order to form a closed space between pipe section 1 andflange 3 for receiving the lead forming the joint. This packing may be in the form ofrope shown at 21 and extends around annulus 4 weones with the ends of the packing overlapping, as

clearly shown in Fig. 6, in order to provide a tight joint While permitting of some circumferential adjustment ot the packing. This packing may be held in position by means of cotter pins 22 received through the packing and through suitable openings provided in the peripheral flange of annulus Land provided With flattened heads 25 engaging the packing.

It will be understood that the lead joint runner may be made in various 'suitable sizes in order to 'adapt the same Jfor various sizes of pipe joints.

In practice the packing for the lead joint runner is preferably made in two semicircular sections in order that it majT be more readily' placed in position Within the runner.

Various changes may be made Without departing 'from the spirit of the invention as claimed.

What is claimed is:

l. A lead joint runner for overlapping pipe sections comprising a recessed annulus upon the inner pipev section and having its periphery overlying the outer pipe section, packing Within the recess of said annulus abutting against the end oit the outer pipe section, and means for securing said annulus in position.

2. A lead joint' runner for overlapping pipe sections comprising a recessed annulus upon the inner pipe section and having its periphery overlying the outer pipe section,

'the

packing within the recess of said annulus abutting against the end of the outer pipe section, means for attaching said packing to said annulus, and means for securing said annulus in position. y

3. A lead joint runner for overlapping pipe sections comprising a recessed annulus upon the inner pipe section, an annulus upon the outer pipe section, and bolts connected to said second annulus with their ends angularly disposed and impinging against the back of the first annulus.

4. A lead joint runner for overlapping pipe sections comprising a recessed annulus upon the inner pipe section, an annulus upon the outer pipe section, and bolts connected to said second annulus and impinging against the back oi the recessed annulus at the eX- treme ends of said bolts which are adjacent the inner pipe section.

5. A lead joint runner for overlapping pipe sections comprising a recessed annulus upon the inner pipe section, an annulus upon outer pipe section, said annuli comprising hinged sections, means for connecting the swinging ends ot the hinged sections ot the for connecting said annuli.

6. A lead joint runner including a recessed annulus adapted to receive a packing annulus having overlapping ends.

In testimony whereof l have signed my name to this specification.
