To all d lzom. it may concern: 1

ie it known that we, WILLIAM ISHAM and FRANK E. Mum-2n, citizens of the United States, residing at Butternut, in thc county of Montcalm and State of Michigan. have invented certain new and useful Improvements in Hmid-iulvcrts and Bank-Retainers; and we do doclnrc the following to be a full, clear, and exact dcseri ption ol' the invention; such as will enable others skilled in the art to which it appertains to make and use the same. v l

This invention relates to improvements in combined road culverts and bank retainers.

.lh 0 object of the invention is to provide an improved road culvert composed of separable interlocking sections by means of which the culvert may be readily set up in position for use.

A further object is to provide an adjustable bank retaining plate or wall adapted to be, secured to "and used in connection with theculvcrt to protect the bank or sides of the roadway at the ends of the culvert, means being provided whereby. said retaining plate or wall may be extehded to any desired length or height and at any desired angle. i i

1 With the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangementof parts, as will be hereinafter descl'ibcd and claimed.

In the accompanying drawings:Figure 1 is a front, vicwof the a culvert and bank retainer constructed in accordance with the invention; Fig. 2 is a top plan view, showing the manner of arranging the sections of the culvert to break joint; Fig. 3 is a vertical cross sectional view of the same looking toward the rear side of thc bank retaining plate or wall; Fig. 4 is a porspec-' live view of one of the side sections of the culvert; Fig. 5 is a similar view of the opposite side section; Fig. 6 is a similar view of the bottom section; Fig. 7 is a detail sectional view through a portion of one end of the culvert and the bank retaining wall, showing the manner ol' (miner-ting these parts together.

ltoforring more particularly to the drawings, 1 denotes the culvert, which consists ofja base section or bottom 2 having on its opposite side edges upwardlyprojecting flanges 3, in which are arranged longitudinally-disposed grooves or channels 4-. p The upper portion of the culvert is formed by side sections 5 and, 6, which curve inwardly at their upper edges and overlap to form the top of the culvert. "he upper edge of the side section 5 is provided with an offset overhanging projection 7, which engages the upper side of the adjacent edge. of the section (5, said upper end of the sec-.

lion U fitting into the offset portion of the section 5, as shown. The lower edges of the side sections 5 and 6 are provided with outwardly-projeeling langes 8, which are adapted to be engaged with the grooves or channels 4 in the opposite edges of the'baseseetion 2.

Formed on' the inper side of the base-section 2 adjecting lugs 9, which are adaptedto engage the adjathe flanges S on the lower edges of the same into ongageinent with the grooves 4 of the base section. on the inner wall of the side section 5 adjacent to the offset projection 7 is formed a. series of lugs 10 adapted to project beneath and engage the inner face of the op .positeside section 6, when the latter is'in engagement with said offset projection. The lugs 9 and 10 serve to effectually prevent the collapsing of the sections of the culvert, thereby forming a strong durable construction, which will readily adjust itself to the expansion and contraction of the metal sections, due to the changes in the weather.

culvert, the sections are arranged to break joint, this being accomplished by providing the sections'at each end Fig. 2 of the drawings.

Adapted to "be used in connection with the culvert retaining walls 12, which preferably consist of a main culvert engaging portion formed of two adj usta'bly connected platcslfi, the inner edges of which are recessed or cut out to 'fit upon the outer surface of the culvert. The .engaging-portions of the plates 13 overlap above and below the-culvert, said overlapping portions being provided with alined slots 14. Through the slots 14 are arranged clamping bo ts 15, by means of which the plates are adjustably sci-" ed together. The outer side edges of the plates 13 are bent at an angle to the plates to provide attaching flanges-16, to which are adapted to be bolted or otherwise secured extension plates 17, of which there may be any desired number, said plates being bolted togethertto form projecting wings, which may be of any desired length depending upon the number of plates thus secured together. The wings formed with respect to the plates 13 forming the main portion of the retaining wall. i

L i angular, rearwardlypro eeting flanges 18 having formed cured to the upper edge of. the main retaining wall, thereby providing for the increase in the height of the retainin g I wall. There. Jay be any desired number of the plates 21, the opposite edges of each of which are bent to cent inner side walls of the side sections 5 and to held,

In assembling the base and side sections to form the of the culvert of unequal length,. as clearly shown in v and secured to one or both ends of the same are bank by the plates 17 may be arranged at any desired angle The'upper edges of the plates 13 are bent to form right therein elongated apertures 19 to receive clamping bolts 20, by means of which top extension plates 21 are sejacent to the opposite edges thereof are upwardly pro- -l'orrn right angular, rearwardly-projecting.attaching flanges, through which are arranged fastening bolts to secure the plates together one above the other, thus pro- '13, the attachment of the top plates thereto will not interfere with the lateral adjustment of said plates 13. The outer ends of each of the end sections of the culvert are provided with radially-projecting substantially V-shaped flanges 22, with'which are engaged one end of zig-zag or z-shaped clips or fastening devices 23. vThe ends of the fastening devices 23 are engaged with the inner edgesof theplates 13 forming thelm'ain "por tion of the wall, therebysecurely: fastening the retain ing wall to'the ends of the culvert. On the innerends of the end sectionsioi the culvert and on the ends of each of the intermediate sections are formed radiallyprojecting flanges24.- These flanges 24 are substantially triangular in cross sectionand havefa: fiat or right angular outer surface, said flat right. angular outer sur a face of the adjoining sections being engaged tov form a close connectionjorjoint between said coincident or adjoining section; I .7

From'the foregoing description, taken in connection Yithth accompanying drawings, the construction and operation of invention will be readily understood without requiring a more extended explanation. 1 .Various changes in the form, proportion and'the mi nor details of construction may be resorted to without departing fro n the principle or sacrificing anyoi the adclaims.

Having thus described our invention, What we claim as new'and desire to secure by Letters-Patent, is:

plates.

and in which the latter fits; said wall beingarranged to bear against the flange and'c onsisting of a pair of'plates just ably connecting the plates,' right angularly disposed 'right-angularly' disposed'iian'ges and provided with slots,

the extension plate to thewnli, and substantially Z-shaped clips having their end portions engaged respectively with the end flangeof the culvert and'withithe inner edge of the retaining wall. i
