Be it known that l, JONATHAN Goon, a citizen of the Dominion of Canada, residing at the town of Didsbury, in the Province of Alberta, in the Doniiuion of Canada, have Improvements in Culvert-Heads or RetainingWalls for Culverts', of which the following is a specification.-

This invention relates to culvert heads or retaining walls for culverts and the primary object of this invention is to provide culvert heads or retaining walls which may be attached to (and detached from) metal pipes in culverts (for the conduction of Water) which will act as retaining walls agents from displacmg the earth, rock and other loose materials from around the ends or the conductor pipe upon which they are attached, and thusact Walls and take the place of staperruanent walls constructed of concrete, stone and similar materials. In dc I shaped scribing the invention in detail, reference Wlll be had to the accompanying drawings 1n which similar letters refer to sunilar parts throughout the several. views and in which:

Figure l, is a side view of a section of an ordinary corrugated metal conductor pipe commonlyhsed in the construction of cul verts, with'the culvert head constructed in accordance with this invention attached thereto.

Fig. 2, is-an endview of the culvert head constructed in accordance with this invention.

Fig. 3, is'a side view of the culvert head constructed in accordance with this invention detached from the conductor pipe.

Figs-t IS an end view of a metal ring used to attach the culvert head supports to the conductor pipe,

Referring more particularly to the drawings A designates four pieces of corrugated sheet metal rigidly riveted together forming a hollow truncated. pyramid or funnel structure (having corrugations run ning parallel to the base) with square base and having a ccmparatively short axis at ri ht angles to the of sheet metal riveted at its outward edges to the smaller end the funnel shaped structure A, and having a centrally locatedcircular ning-;" approximating in diameter the diameter of the end of B which is a corrugated metal conductor pipe ordinarily used and prevent base. P is a square piece inthe construction of culverts. Ris a short piece of cylindrical corrugated sheet inetal pipe having the edges of one end bent outf; right angles and riveted to the end the inner circumference of B so that: R will" fit inside of B tightly. At H, I, J and K are metal rings riveted to A into; which are hooked supporting "metal G. C is a circular metal ring approximating in size the outer circumference oftheconductor pipe B. Attached by bolts to the'ring C at L, M, N and O are the rods D, E, F and G. The size of the entire structure is regulater]. only by size of the conductor pipe B. The culvert head is attached to the corrugated metal conductor pipe B as follows: The cylindrical corrugated metal tube Ris fitted into the end of the conductor pipe B so that the metal sheet P is inv contact with rods D, E, F and laid with a culvert head above set forth at either end or ducto'r pipe B. The earth and other road materials are then packed in over the conductor pipe B and against the inner surfaces of the culvert heads. The culvert heads will thus act as a retaining wall holding the earth "and other road materials in place and preventing them being or displaced by frost quired the culvert head may be detached at any time without injury. s

What I do claim as my inventionand dc} sire to secure by Letters Patent is:

1. The combination with a metal conductor pipe for culverts of a culvert head orretaining wall constructed of four quadrilat eral pieces of corrugated sheet metal riveted together so as toi'orm a hollow truncated pyramid or funnel shaped 'structure with rectangular base (the corrugations running parallel to the base) and having a comparatively short axis with a rectangular piece of,

sheet metal-at the apex of the structure, the

washed away by water or other causes. lf reice said rectangular piece of sheet metal having a centrally located opening of the same size and shape as the end of the conductorpipe with a short piece of corrugated pipe ap-,

proximatin-g in size the size of the opening in the said rectangular piece of sheet metal and being slightly smaller than and of the same shape as the conductor pipe and hav-' ing the edges of one end bent outward at right angles and riveted to the said rectanbound around the short piece of corrugated pipe with draw bolts binding it to the, conductor pipe, with four metal rods hooked into'met-al rings riveted to the outer basal edge of the pyramid, a metal ring firmly drawn around the conductor pipe by a bolt and Iiut into which are bolted the outer ends of the said rods, the axis of the conductor pipe being at right angles to the base of the said pyramid or funnel shaped structure.

2. The combination with a conductor pipe for culverts of a culvert head or retaining wall constructed of four quadrilateral pieces of sheet metal riveted together so as to liorm a hollow truncated pyramid or funnel shaped structure with rectangular base'with I a rectangular piece of sheet metal at the apex of the structure'the said rectangular piece of sheet metal having a centrally located opening approximating 111 size and.

shape the size and shape of the end of the said conductor pipe a. short piece of metal piping being slightly smaller than and of the same shape as the conductor pipe and having the edges ofone end bent upward at right angles and riveted to the said rectaniaaaeee sheet metal and with a metal band bound around the short piece of pipe with draw bolts binding it to the conductor pipe, with four metal rods hooked into metal rings riv eted to the outer basal edge of'the pyramid, a metal ring firmly drawn around the conductor pipe by a bolt and nut into which are bolted the outer ends of the saidrods' 3. The combination witha metal conductor pipe of a hollovt truncated pyramid or funnel shaped structure having a 001m paratively short axis with a piece ofsheet metal completely covering and fastened to the apex of the said truncated pyramid, having a centrally located opening in it of the same shape and size as the end of the conductor ,pipe with a short piece of pipe approximating in size the size of the opening in the said piece of sheet-metal and being slightly smaller than, and of the same shape as the conductor pipe, the said short piece of pipe being fastened to the said piece of sheet metal covering the apex of the said truncated pyramid and with a metal band drawn around the said short piece of pipe with draw bolts the whole structure being held to the conductorpipe by four. metal rods or chains hooked into metal rings fastened to the outer basal edge of the said pyramid, the outer ends of the said rods or chains being fastened to a metal ring or rod firmly drawn around the conductor pipe.
