WATER PIPE PROTECTIVE DEVICE Filed Dec. 4, 1959 WA 75? MA V INVENTOR Gina EE mu fiuluacri ATTORNEY United States atent 3,009,483 WATER PIPE PROTECTIVE DEVICE Giaocemo Salustri, 581 Adams St., Boston, Mass. Filed Dec. 4, 1959, Ser. No. 857,449 Claims. (Cl. 138109) This invention is concerned with water mains and their terminations Within a building. The invention is directed towards those water mains which are mounted within a guard pipe, often described as a pipe within a pipe.

In most cities it is contemplated that the feeder or trunk line'from the water main will be mounted within a pipe so as to eliminate outside rust and corrosion. The purpose of this is to eliminate the expense of replacing the feeder line. It is also a much simpler operation to replace the feeder line. It is also a much simpler operation to replace the feeder when it is within a pipe. Excavation of the earth is eliminated. The termination of thefeeder line within the building has left many problems. The open pipe within the pipe makes an open highway for rodents to enter the building. These rodents may walk down the inside shell from many other areas. There is also the problem of jumping the feeder in front of the water meter, thus cheating the municipality out of payment for the use of the water.

It is an object of the within invention to provide a means for closing oif and sealing the outside pipe and permitting the feeder inside pipe to pass therethrough.

It is an other object of this invention to provide a termination means for the outside pipe that can be opened easily for the purpose of making repairs in the feeder pipe.

It is yet another object of the within invention to provide a novel structure that is semi-permanent for closing the end of the outer pipe.

It is still a further object of the within invention to provide'means at the end of the outside pipe for preventing the' inside pipe from being jumped before the meter.

These and other objects are obtained by the use of a termination 'assemblyin the shape of a pipe which overlaps the outer pipe which enters from the outside. The terminatio-nassernbly which overlaps has a unique arrangement for permitting one to obtain entry therein and also has a novel means for supporting the inner pipe. In addition to the termination arrangement, there is also an auxiliary unit which is in the nature of a box assembly that fits over the junction between the water pipe line and the meter so that no tampering can be done. In both instances the termination arrangement and the junction box are closed and locked with the conventional seal which can only be broken. Accordingly if an inlspection were made, it would be apparent that there has been tampering with the water pipes.

For a more detailed description of the within invention, reference is made to the following specification and to the drawing in which: FIGURE 1 is a side elevational view of the entire assembly, showing the termination arrangement and the junction box.

FIGURE 2 is a perspective view of the junction box in an exploded form.

The water main 34 is generally located under a street, and connected to the water main is the feeder or trunk water pipe line 1, which is within the protective cover or outer pipe 2. The purpose of the protective pipe or cover 2 is wellknown and is merely to make it much more simple to remove the inner pipe 1 if and when it becomes rusted out or corroded and also to prevent rust and corrosion of the inner water pipe. The inner pipe 1, in order to be maintained within the approximate center of the outer pipe 2 is mounted by means of a U-shaped clamp 3 through which a support bolt or pin 4 passes.

The support bolt 4 passes through an opening in the surface 10 of the outer portion 'of the termination arrangement and passes through a similar opening within the outer pipe 2 through openings in the U clamp 3 through a bottom opening in the outer pipe 2 and again the surface 10 of the termination arrangement. There is an opening 15 in the supportbolt'4 through which the seal 11 is fastened. The opening in the U clamp 3 is indicated in the drawing by the numeral 5 but is not clearly shown since it is apparent. The openings through the surface 10 and the outer pipe 2 are clearly shown in the cross-section view of FIGURE 7 and are indicated by the upper opening 8 and the lower 9.

The surface 10 of the termination or closure assembly is not an integral surface since at the very end of the assembly there is a movable surface 13 which fits over the inside surface which is not movable.

The surface 13 is in the'nature of a cut out from the surface 10 while the surface 12 is just the bottom portion of the surface 10 beneath the movable'surface 13.

In addition to the U-shaped clamp supporting the pipe 1 there is at the very end 19 of the surface 10 a'neck or supporting surface 7 for the inner water pipe 1. This surface 7 can be seen in the view of FIGURE 3 and also the view of FIGURE 7. The movable surface 13 and the fixed surface 12 beneath it have complimentary locking flanges. The flange 6 is on the surface 12 and the flange 18 is on the movable surface 13 and when they are closed that is when the surface 13 is in position over surface 12, the flanges 18 and 6 are above each other and again a seal 11 is placed there through. The surface 13 is mounted to the surface 12 by. means of a hinge 25 which is of a conventional type. The purpose for the design of the surfaces 12 and 13 is to enable the maintenance man to gain easy entrance into the termination assembly, for example, to connect or remove the fitting 17. a

With regard to the termination assembly, it is apparent that only if the seal 11 is broken inthe flange 6 and 18 could the fitting 17 be touched. Any tampering done elsewhere along the pipe would'be apparently noiced and anyone inspecting the pipe from the water department or from the supplier of the water would be put on notice that some larceny would have been committed or was being committed. To complete the insurance against this larceny and against tampering with the water line 1, (it is necessary, of course, to have the water pipe 1 connected into the water meter 24) there must be some means to lock the coupling or fittings 23 so that no tampering can be done with these either.

Going back to FIGURE 1 the valve assembly 16 is a safety device for turning off the water in the event an emergency arises. This is conventional. The valve assembly 16 is connected into the fittings 23 which connect the water pipe 1 with the conventional meter 24.

Circumscribing the fittings 23 is the box assembly 21 and 22. The box assembly comprising the lower box 21 and the upper box 22 is assembled very simply. In the upper segment of the box 22 there is an opening in the flange 33 which flange protrusion extends down into the slotted opening 32 in the lower box segment 21. Behind the flange 33 and to the rear of the upper box segment 22 are a pair of slotted openings 30 which are in the shape of the cross section of the tongues 31 which extend from the rear of the bottom of the box 21. The openings 30 are complementary to the tongues 31 and when the upper portion of the box 22 is assembled with the lower portion of the box 21, these tongues 31 pass through openings 30, as shown. The upper box segment 22 has a cut out and curved surface 27 in each of its ends as can be seen in FIGURES 2 and 8. These cut outs 27 in the ends 26 slide over the ends 28 of the lower box 21 and together with the curved cut out surface 29 in the lower box 21 form the opening 20 shown in FIGURE 8.

In putting the box assembly 21, 22 around the fitting 23, it is merely necessary to put the lower segment 21 beneath the pipe 1, slide the upper portion onto the tongues 31 through the openings 30 and permit the front flange 33 to drop down into the slotted openings 32. At this point the fitting 23 is within the box 21, 22 snuggly since the contour of the curve 27 and the curve 29 in the upper and bottom segments respectively form the Opening 20 (FIGURE 8) to circumscribe tightly the pipe 1.

The conventional seal 11 is then placed through the opening in the flange 33 and the assembly is securely locked. The only way that the assembly could be removed is by breaking the lock seal 11 or defacing the assembly itself and this would be apparent to the investigators from the water department. Consequently jumping the meter would be eliminated.

It is contemplated that there may be modifications of structure without departing from the spirit and scope of the invention.

Dimensions of the drawings have been exaggerated to teach more clearly the invention.
