CULVERT.

` Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed August 9, 1915. Serial No. 44,529.

To all 'whom t may concern Be it known that I, SAMUEL E. MOORE, a citizen of the United States, residing at Williamsville, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Culverts, of which the following is a specification.

The invention relates primarily to culverts such as are used under roadways and have relatively small openings which render it impracticable for a man of ordinary size to enter the culverts for the purpose of cleaning them out.

A general purpose of the invention is to provide a culvert comprising a series of sections which may be made separately at a relatively small cost and may be easily assembled where the culvert is to be installed and the number of sections to be used may be varied to suit the length of the culvert.

Other purposes of the invention are: To provide in conjunction with abutments at the ends of the culvert a series of intermediate bottom sections, tie rods external to the bottom sections and adapted to rigidly connect the abutments and the bottom sections and a series of removable cover sec tions intermediate with respect to the abutments and breaking` joints with the bottom sections; to provide an abutment at one end of the culvert having a bottom member of a length 4different from the -length of the respective intermediate bottom sections and to provide an abutment at the other end of the culvert having a cover member of a length different from the length of the respective intermediate cover sections.

The invention is illustrated in the annexed drawing and will be hereinafter particularly described and finally recited in the claims.

Figures 1 and 2 are respectively a side elevation and an end elevation of a culvert embodying my invention. Fig. 3 is a vertical transverse section on the line Y. Y. of Fig. 1, and Fig. 4 is a vertical longitudinal section on the line X. X. of Fig. 2.

Similar reference numerals designate like parts in the different views.

The culvert will preferably be made of concrete, but iron, or clay hardened by burning, or other suitable material may be used without departure from my invention.

The abutment 1 has an integral bottom member 2 conformed to the contour of the adjacent bottom section and preferably of half the length of the bottom section.- The bottom sections 3 are all alike and preferably are of trough-shape cross-section as shown in Fig. 3.

The abutment 4 has an integral covermember 5 of arcuate cross-section, preferably half the length ofv and somewhat thicker than the adjacent cover section and conformed to the contour of the cover section. The abutment 4 also has an integral ledge 6 adapted to support the end of the adjacent bottom section. The cover-member 5 is complemental to and is thicker than the cover sections?, to strengthen the covermember so as to avoid breakage during the handling of the abutment.

The bottom member 2 of the abutment 1 and the cover member 5 of the abutment 4 extend inwardly in alinement with each other and have two functions, viz: they serve as spaces to position the parts so that the cover sections 7 will break joints with the bottom sections 3, and also serve to prevent lateral movement, or turning, or disalinement of the abutments.

The cover sections are all alike and are preferably of arcuate cross section and have longitudinal flanges 8 adapted to engage on the side walls of the bottom sections, as shown in Fig. 3 to prevent lateral displace ment of the cover sections.

The abutments l and 4 have transverse holes 9 adapted to accommodate tie rods 10. The holes 9 are placed so thatwhen the parts are assembled the holes in one abutment will be in line with the holes in the other abutment andthe tie rods 10 will be parallel to each other and external to the bottom sections 3. The purpose of this arrangement is, that if it be desired to remove any bottom section, it may be lifted out and another section substituted without disturbing the other bottom sections or the abutments.

Washers 12, free on the rods 10, contact with the faces of the abutments. Nuts 13 screw onto the rods 10 and bear against the washers 12.

When installing the culvert, the ground will be graded and a suitable bed will be prepared as is usual in the art. The abutment l will then be placed in position, the number of bottom sections necessary for the culvert of the required length will be placed on the bed in line with the bottom member 2 so that the end of' one section will abut against the free end of the member 2 and the sections will lie end to end against each other, the abutment l will be placed with the ledge 6 under that terminal of the section 3 which is adjacent to the abutment 4 and with the inner face or" the abutment in close contact with the outer end of the section, the tie rods l0 will be placed in the holes 9 and the washers 12 and the nuts 13 will be placed on the rods and the nuts will be tightened to firmly connect together the abutments and the bottom sections; and the cover sections 7 will then be laid on top of the bottom sections 3 so that the cover sections will lie end to end, one end of one terminal section will be adjacent to the inner face of the abutment l and one end of the other terminal section will be adjacent to the free end of the cover men'iber The cover sections 7 are just a little shorter than the bottom sections 3, in order that when the abutments l and '-l and the bottom sections 3 have been assembled and tied together by the rods l0, the cover sections may be freely placed lon or removed from the bottom sections.

I have described the assembling ot the parts as beginning with the left hand abutment and progressing toward the right, but it is obvious that the assembling may begin with the right hand abutment and progress toward the left.

If the culvert becomes obstructed, the earth immediately above the obstructed section or sections may be dug out without disturbing other parts of the roadway, the cover section or sections may be lifted off, the obstruction may be removed, the cover section or sections restored and the excavation rclled without disturbing the other elements of' the culvert.

I am aware that sectional culverts have been used and that removable cover sections have been used. I therefore do not broadly claim those features of construction.

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

l. In a culvert, the combination of a first abutment having a. trough-shaped bottom member integral with and at right angles to the abutment and adapted to serve as a spacer and also adapted to prevent lateral movement or turning of the abutment; a second abutment having a cover member integral ywith and at right angles to said second abutment and adapted to serve as a spacer and also adapted to prevent lateral movement or turning of said second abutment; bottom sections in line with the bottom member of the first abutment, one end of one terminal section being in close contact with the free end of said first abutment and one end of the other terminal section being in close contact with the inner face of said second abutment; connecting devices rigidly connecting said abutments and said bottom sections; and removable cover sections practically filling the space between the inner face of said first abutment and the inner end of the cover-member of said' second abutment.

2. In a culvert, the combination of' a first abutment having an inwardly extending bottom member integral with and at rightv angles to said first abutment and adapted to serve as a spacer and adapted to prevent lateral movement of' the abutment; a complemental abutment having an inwardly extending cover-member integral with and at right angles to said complemental abutment and adapted to serve as a spacer and adapted to prevent lateral movement of said complemental abutment; bottom sections in line with said complemental abutment and with the bottom member of said first named abutment; connecting devices outside of and parallel to the alined bottom sections and rigidly connecting the abutments and the bottom sections; and end-to-end cover sections occupying practically the entire space between the inner end of the cover' member of said complemental abutment and the inner face of said first abutment'.

3. In a culvert, the combination of a first abutment having an integral inwardly extended member at an angle to the abutment and adapted to serve as a spacer and adapted to prevent lateral movement of said first abutment; a second abutment having an integral inwardly extended member at an angle to said second abutment and adapted to serve as a spacer and adapted to prevent lateral movement of said second abutment; bottom sections intermediate of the abutments; and cover sections intermediate of the abutments and breaking joints with the bottom sections.

4L. In a culvert, the 'combination of a first abutment having two holes parallel. to each other and adapted to accommodate bolts, also having an integral inwardly extended member atI an angle to the abutment and adapted to serve as a spacer and adapted to prevent lateral movement or turning of the abutment; a second abutment having two holes parallel to each other and adapted to accommodate bolts, also having an integral inwardly extended member at an angle to said second abutment and adapted to serve as a spacer and adapted to prevent lateral movement or turning ofsaid second abutment; alined bottom sections intermediate of the abutments; alined sepa- In lWitness whereof I have hereunto signed my name at Springfield, Illinois, this 6th day of August, 1915.
