cULvEmx.

To all ,whom it/may concern.

. Be it known that I, CHARLESv A,.F osTER, a citizen of the United States, residlng at Portland, in the county of Multnomah and State'` of Oregon, have invented a new and useful Culvert, of which the following is a specification.

My invention relates to ,culvert constructions and has for its object the provision of an abutment adapted to be secured to the intake end of a culvert to prevent the dirt around the mouth of the culvert from being -v washed away by the action Vof the water which flows through the culvert. 4

Referring to the accompanying drawings, Figure 1 is a. perspective view showing a culvert section and the two sections of my new formof abutment, which are adapted ytofit snugly around the culvert section, the parts being in this figure shown disassembled, Fig. `2 shows the parts of Fig. 1 assembled in operative relation, F ig. 3 is a view showing a different form of culvert 4section and a correspondingly modified abutment plate to be secured thereto, the figure showing the parts disassembled, and Fig. 4 is a view showing the parts of Fig. 3 assembled in operative relation.

v is substantially circular.- When the culvert is* constructed of corrugated sheet metal, as

In its preferred form my novel form of abutment comprises a pair of complementary plates 1 and 2 constructed of corrugated sheet metal. These plates are recessed at 3 and 4, respectively, the precise configuration of the recesses depending on the shape of the culvert-to which the abutment is attached.

-In Figs. l and 2, the abutment is shown in when the plates 1 and 2 are brought together the opening formed by the recesses 3 and 4 it preferably will be, the size of theopening formed by the recesses Band 4 is such that the abutment plates snugly fit into one of the corrugations of the culvert. This is shown inthe assembly view of Fig. 2. The plates v1 and 2 are provided with lateral anges 6 and 7. When the plates are assembled these lateral anges 6 and 7 abut c against each other, as shown in Figs; 2 and 4.

, Suitable fastening devices 8, such as bolts or rivets, pass'through the flanges 6 andl 7 and firmly hold the abutment plates together on the culvert.

Specification of Letters Patent. Application led December 19, 1910. Serial No. 598,259.

' In Figs. 3 anu 4 the abutment is-shown' in connection with a culvert having a` fiat bottom 9 and an arched upper piece 10. In this case the recesses 3 and 4 of the abutment .are of such configuration that when thel abutment plates are secured in place on the culvert the plates snugly embrace the culvert section.

It will be seen from the above description that the lateral abutting flanges' afford simple and effective means for securely hold! ing the plates in position on the culvert. Although I have herein shown the abutment as constructed of two complementary plates, it is obvious that the number of such .plates may be varied. For instance, 'in case of abutmentsv of .large dimensions, it may be that more than two plates wonld be required to build up the abutment economically.

Patented Juiy 11, 1911.`

However, for ordinary culverts, a pairv of l complementary plates will .be sulicient to make up the abutment.

kHaving thus described my invention what I claim as new and desireto secure by Letters Patent of the United States is:

1. The combination with a culvert, of an` abutment therefor, saidabutment comprising a plurality of complementary plates constructed to fit aroundthe `body of theculvert, the contiguous edges of said plates being provided with lateral flanges which extend at right angles to the body of the plates and are adapted to abut against each other when the plates are brought together into operative position, and securing means engagingsaid flanges for holding the plates rigidly together on the culvert.

2. The combination with a corrugated metal culvert, of an abutment therefor, said abutment comprising a plurality of complementary plates constructed to tit snugly into one of the corrugations of the culvert, the

contiguous edges of said plates being pro` are adapted to abut against each other when the plates are brought together into opera.- tive position, and securing means'engaging said flanges to hold the plate rigidly together on the culvert.

3. The combination with a corrugatedmetal culvert, of an abutment therefor, said yabutment comprising a plurality of complementary lates constructed of corrugated metal to t snugly into one of the corrugations of the culvert, the contiguous edges of said plates` being provided with lateral ang'es Whichextend at right angles to the body of the plates and are adapted to abut .against each other when the plates are brought together into operative position, and' securing means engaging said flanges to hold the plates rigidly together on the culvert.

et. The combination with a culvert, of an abutment therefor, said abutment comprising a plurality of complementary plates of corrugated Ametal constructed to t around the body of Athe culvert, the contiguous edges of said4 plates being provided with lateral flanges which extend at right angles to the body of the plates and are adapted to abut against each other when the plates are brought together into operative position, and securing means engaging said ianges to hold the plates rigidly together on the culvert.

5. The combination with a culvert, of an abutment therefor, said abutment comprising a` plurality of complementary plates constructedof corrugated metal to fit around into one ofthe'corrugations of the culvert,

lateral abutting flanges provided on the contiguous edges of said plates and running transversely to the corrugations on the plates, and securing means engaging said flanges to hold the plates rigidly together on the culvert. l 7 The combination With a culvert, of an abutment therefor, said abutment comprising a plurality of complementary platesconstructed to t around the body ofthe culvert, the contiguous edges of said platesbeing provided with lateral flanges which extend at right angles to the body of the plates and are adapted to abut against eachother when the plates are brought together into operative position, and .bolts passing through said flanges for holding gether on the culvert.

8. The combination with a culvert, of an abutment therefor, said abutment comprising a plurality ofcomplementary plates of corrugated metal constructed to it around the body of the culvert, the contiguousedges of said plates `being provided with lateral ilanges which extend at right angles 4to the body of the plates and are adapted to abut agalnst each' other When the plates are the plates rigidly tobrought together into operative position, and

bolts passing through said flanges to hold the plates rigidly together on the culvert.y

In witness whereof, I hereunto subscribe my name this 9 day of Dec. A. D. 1910. s
