BANNON, OF LOUISVILLE, KENTUCKY.;
SEPLRABLE EARTHEN INSULATING PIPE-COND'UI1 Specification of Letters Patent.
Patented se t. s, 1914.
Application filed September 30, 1912. Serial No. 723,206.
ot' the character specified, having oppositely arranged pairs of longitudinal scores or cuts at each side, arranged to permit the upper half of the conduit to. be easily and expeditiously separated from the lower half, to
permit the insertion of the pipe.
A further object is to arrange the said scores or cuts that they will insure the fracture of the conduit along the line of the said scores or cuts, without injuring the remainder of the conduit.
A further object is to arrange the scores or cuts in such manner that a waterproofing cement may be laid in the cuts for securing the halves of the conduit together after it has been laid. g
A further object is to provide additional supporting means on the outside of the conduit for the cement,
In the drawings :F igure 1,- is a perspective view of a sect-ion of conduit constructed cross. sectional shape, and the sections of the conduit may be of any desired length and diameter in accordance With the conditions to be met.
In thepresent instance each section 1 of the conduit is provided at one end with an outwardly offset annular flange 2, for receiving the adjacent end of the succeeding joint. Each of the said sections is provided at each side with a pair of innerand outer longitudinal scores or cuts 3, and 4 respectively. Each conduit has two pairs of scores or cuts and the pairs are at angular distances of 180; The scores or cuts 3 and 4 extend inwardly and downwardly, each out being of considerable depth, so thata suflicient portion-of the thickness of the conduit is .left at each side to hold the, sections together,-,yvhile at the same time the said 'sec-' tionsj may be easily separated, by breaking the uncut portions,
It will. be noted that each of the cuts 3 and 4 is approximately wedge shaped, that 1s, each of the said cuts is widest at its commencement, and gradually decreases in width inwardly. Each cut is also inclined downwardly, and it will be evident that when a tool as for instance, a chisel is inserted in the cut, and pressure is brought to bear on the tool in the proper direction, that portion 5 of the thickness of the conduit be tween the adjacent edges of the cuts 3 .and 4 will be fractured or broken as shown in Flg. 3 to permit the-upper half of the conduit to be lifted away from the lower half.
The lower half of the conduit is provided on each side of the center of its bottom with a longitudinally extending rib or ledge 6, the upper face of each rib or ledge being horizontal and the inner face vertical as shown, and the upperfaces of the two ledges are in the same plane. The ribs or ledges 6 are strengthening and reinforcing ribs, designed to strengthen and reinforce that particular portion of the conduit which especially needs such strengthening and reinforcing, namely, that portion which receives and supports the direct weight of the matter which is designed to pass through the pipe, either piping or anything else. Each rib or ledge is rovided at spaced intervals with two notc es 7, the notches of the two ribs being directly opposite each other.
The improved conduit isespecially adapted for use with the-traveling pipe supports shown in my prior applications, Serial Number 709,262, filed Jul 13,1912, and Serial Number 720,524, file September 16, 1912, and the arrangement of the notches will depend upon which of the saidsupports is used. If the cradle or base is used, with the conduit, the notches will be arranged in pairs, as shown more particularly in Fig, 1, and each notch will have its bottom wall rounded as shown at 8, in the said figure.
If the cradle is omitted, and the roller with projected journal pins used, the notches 7 may be single, that is, each rib will have a singlenotch for each support, one journal pm engaging the notch of one rib and the other the notch of the opposite rib.
When the two halves of the conduit are reassembled, it will be evident that the fractured surface of the other half will fit the fractured surface of the lower half at each side, and plastic material 9, as for instance, water proofing cement, is arranged within the scores or cuts 8 and l, thus effectually sealing the joint. On the outer side of the conduit, the lower halfis provided at each side with the outwardly extending rib or ledge 10, the upper face 11 of the said rib or ledge being horizontal and flat, while the lower face 12 is rounded as shown in Figs.
2' and 3. The upper face of the said rib or ledge 10 provides an additional support for the cement 9, and the said cement maybe arranged as shown in Fig. 3, to defiect water from entering the joint or from resting on the ledge. The arrangement of the scores or cuts, that is, inclining inwardly and downwardly provides a shallow trench for receiving the cement.
To insure that the fracture will follow the portion at each side of the conduit, a lon- Q'itudinal rib 13 is provided'on the upper half of the pipe just above the score or cut 3, the said rib being rounded as shown. The upper haif is thus reinforced or strength ened at each edge and the lower half is similarly reinforced or strengthened by means of the rib 10. The said ribs 1.0 and 13 con strain the line of fracture to run between the scores or cuts, and the rib or ledge performs three functions, first, a ledge for bold ing the cement, second a reinforcing rib at the fractured edge of the lower, and third, a means of insuring that the line of fracture will follow the portion 5 of the conduit.
The rib 13 performs two functions, first, that of reinforcing or strengthening the edge of the upper half and second a means of insuring that the line of fracture will run true. The ribs or ledges 6 not only furnish a sup porting means for the traveling supports for the pipe, but also strengthen the conduit. The inclined arrangement of the scores or cuts hold the cement in place, thus insuring not only a secure joint but a better and safer alinement of the two parts.
The internal ribs 6 and the notches 7 are not claimed in the present application, this construction forming the subject matter of my application, Serial No. 782,661, filed August 2, 1913, which is in part a divisiona application of the present case.
