the following is a specification.

' This invention-relates to-certain improvewhile at the same sary to prevent 'accom an g p ylibreto appended 1t being underchanges in form propor-f principle or sacrificing `when the water in .tent as to ments in sectional culverts of'tha't generalv class designed for use -beneath railway-` tracks, roadways and thelike or in the construction of sewers, conduits 4and similar structures. of this character it has heretofore been -the custom to mold or otherwise form the several sections vof the culvert with interlocking lugs and to provide the adjacent edges thereof with seating flanges to permit independent lateralvmovementof the several sections when the water in the culvert freezes. It has been found by experience, however, that eral pressure on the walls of the culvert sections will dis lace said sections toA such an eX- isengage the locking lugs and thereby cause the culvert to collapse when the ice in the latter melts.

The object of the present invention is to obviate this difficulty vvby providing means for limiting the lateral movement of the several culvert sections so that said sections will be retained in constant engagement with each other regardless of climatic conditions time permitting the requisite lateral movement of said sections necesinjury to the same when sub-V jected to internal pressure.

With thesev and other objects in view the invention consists in the 'construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the drawings and pointed out in the claims stood that various tions and minor details of construction may be resorted to without departing from` the any of the advantages of the invention.

Fig; 2 is -asimilar view illustrating a modified form'4 of the invention. Fig. 2v is a perspective view s ective view vresidingat Charlotte, in the county Y In the manufacture of culverts the culvert freezes the lat- .showing a modied form of Fig. 2. Fig.v 4 is a perspective view illustrating a further modijication.

showing each section ofthe culvert provided with parallel ribs -for the 'reception of the unobstructed edge, of the adjacent section. Fig. 6 is a similar view vshowing the opposite longitudinal edges of the base section provided .with'parallel ribs. 'Fig.'7 is a perspec- Vtive view ofa furtherl modification in which the culvert sections are formed withdovetailed interlocking lugs. Fig. 8 is a similar view of a still fur her modification wherein the interlocking lugs are formed of angle iron. l

Similar numerals of reference indicate corresponding parts in all [the figures of the drawings.

for the purpose of lillustrating the dierent ways of accomplishing the same result namely; preventing excessive lateral movement of the culvert sections.

metal or other suitable material are preferably triangular in cross section, as shown, and each comprises a base 5 and sectional side plates 6 and 7. The plates are made in and arranged to dinal junctures, said'plates being preferably slightly curved or bowedin cross section and formed with a seriesof transversely disposed strengthening ribs orV corrugations 8, varying in number and distance apart according to the size of the plates and strength required for thel culvert.. l

In the preferred form of the invention, shownin Fig.. 1 of the drawings, the plates are interchangeable and each provided atits opposite lo Oitudinal edges wltha plurality o spaced loc 'ng' lugs 9 adapted to interlock with the corresponding lugs of an adjacent section when the several sections are assembled, said lugs forming. interrupted seating flanges 9 for theedges of the plates whereby said plates are free to move aterally 'when the water inthe culvert freezes. ing lugs 9 are formed with lateral projections orflanges 10, portions of adjacent plates and serve-to limit the lateral movement of said plates when the water inthe culvert freezes.

In Fig.v5 there is illustrated a further modification in which leach plate is'formed at the edge thereof With a longitudinally disposed.

upwardly extending rib 20 defining a seating flange 21 and provided at intervals with notches or recesses'22 adapted to receive spaced locking lugs 23 projecting from the.

inner face of the plate lat the opposite edge thereof, there being a similar long1tudinal rib or flange 24 formed on `one ed e of each-plate and s` aced from the rib 20 or limiting the latera movement of said plates. j'

while in Fig. 8 the dovetailed locking lugs 26 are Vformed of angle iron, as shownfthereb serving to reinforce and strengthen the cu -V vert and at the same timelimit the' lateral movement of the independent sections.
