To all whom it may concern:

Be it known that l, FRnonmoK H. Sonora, a citizen of the United States, residing at Lansdale, in the countyof Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Goncrete Road-Culverts, of which the following is a specification.

My invention consists of an improved concrete road culvert, such for example as may be inserted under a road for draining water from one side of the road to the other, how ever, it will be understood that my invention may be used as a drain or culvert in other locations.

One object of my invention is to provide a drain or culvert which is made up of reinforced concrete sections, said sections including pipes which have similar flanges at each end which are held together by coupling sleeve sections, the ends of the pipe adjacentthe sides of the road being secured within reinforced walls or plates in such manner as to prevent longitudinal movement.

Another object of my invention is to provide said walls with grooved holes through which concrete in a liquid state may be in.- serted so that after said inserted concrete has set, it acts to lock the pipes to the walls. A further object of my invention is to provide said walls with an lar sleeves, preferably of metal, which Wlll serve as the securing means for a sign post or a post of any other description.

Another object of my invention is to so make the pipe sections that both end flanges will be identical so that the pipes will roll in a straight path so that they may be conveniently loaded in freight cars or stacked for storage purposes.

Another object of my invention is to make the coupling sleeves in sections and reinforce each section to prevent pressure from cracking or otherwise-injuring them.

A still further object of my invention is to provide said coupling sections with internal flanges which act as shoulders for the pipe flanges thereby keeping said pipes intheir proper position.

Another object of my invention is to so construct my improved drain that it may be manufactured and sold at a comparatively low cost, and will be strong and durable.

CONCRETE ROAD-CULVERT.

which will be described hereinafter, 1 attain 1n the following manner, reference being had to the accompanying drawings in which- Figure 1 is a longitudinal sectional elevation of my improved drain or culvert as it appears when extending transversely across a road. Fig. 2 is a fragmentary perspect1ve view showing my improved buttress wall having a pipe secured therein. Fig. 3 1s a sectional plan view taken on the line a-a of Fig. 2. Fig. 4: is a perspective view of one section of a sectional coupling which employ to secure the ends of my improved p1pes together. Fig. 5 is a face view of a modified form of my improved buttress wall or plate and made in interlocked sections, the body of the drain pipe being shown in sec- .tion. Fig. 6 is an end view.

Referring to the drawings, 1 represents the roadbed having my improved buttress walls 2 and 3 located at opposite edge portions. Each of these walls is identical in construction and has a circular hole A which extends entirely therethrough and of such diameter as to admit the flanged end 5 of an end pipe section 6. lhe wall forming said hole A is recessed or grooved 'annularly as shown at 7, said groove being preferably located centrally between the outer and inner faces 8 and 9 of the wall. A passageway 10 communicates with the groove 7, and extends at an incline to and intersects the face 9 of the wall, said passage acting as a port hole for liquid cement as will hereinafter be more fully described. Each wall 2 and 3 is also reinforced by metallic wire 11, preferably in a screened form, and the portions of said walls 2 and 3 which are above the flanged ends of the end pipes 6, act to prevent the top or surface portion 12 of the road from washing or otherwise breaking away adjacent the edges.

All of the flanges of the pipe sections are made identical, and these flanges at positions intermediate the walls 2 and 3, are secured together by sectional coupling sleeves 13, one

of which is clearly shown in perspective in Fig. A.

Each of the sectionslf, comprising the coupling sleeves, is recessed at 15 between its side surfaces to provide flanges 16 and 17 said flanges providing shoulders against which the flanges of the pipe sections abutfi and it will be noted that the recess 15 1s 0 suficient width to receive two abutting flanges of two pipe sections.

Each of the sections 14 of the coupling sleeves 13 is provided with a segmental reinforcing screen, preferably of metallic mm as shown at 18, thereby serving to resist pressure of the road and tenslon of the pipe sections. The pipe sections also have reinforcing means as indicated at 6. This means as illustrated consists of a metallic wire screen which is embedded throughout the length of the pipe and extending circumferentially thereof.

A metallic sleeve or bushing 19 extends through each of the walls 2 and 3, and is preferably made angular as shown in Fig. 2. This bushing is grooved intermediate its ends as shown at 20 (Fig. 3) and is embedded in the concrete which forms said walls.

In assembling my improved drain, the intermediate ends of the pipe sections are inclosed within the coupling sleeves, and the outer end flanges 5 are positioned within the holes 4 of the walls 2 and 3, so that the outer ends of said pipe are substantially flush with the outer faces 8 of the walls.

The width of the flanges 5 is such that the inner surfaces of .said flanges coincide with the faces 21 of said grooves 7. When the flanges are so inserted, there is an opening which surrounds the body portion of the pipe section 6, and this opening is filled with cement through the passages 10. In order to prevent the liquid cement from continuously running out of said opening, the opening may be banked by a few hands full of mud to form a seal at the inner faces 9 of the wall, said seal acting to confine the liquid cement within the grooves 7 and the opening just referred to. After this cement has set, it forms an interlock which prevents the flanges 5 from pulling out through the portion of the holes through which they were inserted. In other words, it absolutelylocks the flanges 5.to the walls 2 and 3.

In the form of my invention shown in Figs. 5 and 6, the wall is substantially identical with either of the walls 2 and 3 with the exception that it is made in sections as shown at 22 and 23, these sections being tongued and grooved as shown at 24, the dividing line extending in a substantial horizontal direction. In all other respects the construction isidentical'to the form above described, and I have therefore given the same like reference numerals. I

In a drain or culvert constructed inaccordance with my invention, the pipe sections are strong and firmly held together.- The manner in which I construct the buttress walls and insert and secure the ends of the drain pipes within the walls provides a rigid buttress both for the sides of the roadbed and for the ends of the pipe sections.

The walls present-an extremely neat appearance, all portions of the walls being flush on their outer faces, which renders them especially desirable as an ornamental feature.

My invention provides an extremely practical drain and the cost of installation is such that it may be easily adopted by-townships and counties throughout the different States which desire an extremely durable and eflicient drain or culvert.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed with out departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination in a culvert, of end Sections forming walls and having holes extending therethrough, pipes extending between said walls and having flanges fitting within the holes in said walls, grooves intersecting said holes and adjacent said flanges, and filling material fitting within said grooves and acting to abut said flanges, said filling material forming an interlock to retain said pipes within the walls, substantially as described.
