JAMES B. JARMIN, OF SPOKANE, WASHINGTON, ASSIGNOR OF ONE-HALF TO JOHN S.

METAL CULVERT.

To all whom it may concern:

Be it known that I, JAMES B. JARMIN, a citizen of the United States, residing at 1908 Broadway avenue, in the city of Spokane, county of Spokane, Stateof Washington, have invented a new and useful Metal Cut vert, of which the following is aspecification.

The object is to provide a metal culvert pipe having a flat bottom and a curved top of a general semi-cylindrical shape, both the top and bottom portions of which are made of short sections so joined together and in suflicient numbers to form a completed culvert pipe and so arranged that the inside of the bottom will be smooth and free from any obstruction and serve as a base upon which the lower edges of the upper portion may rest, said bottom having flanges along the edges thereof to which flanges the lower edges of the upper portion are bolted, all parts being nestible for the purpose of easy transportation to the place of erection. I attain this object by the novel composition and arrangement of parts as hereinafter fully described and illustrated in the accompanying drawing in which Figure I. is a perspective View of an assembled pipe. Fig. II. shows a completed pipe in process of assembling at the place of erection. Fig. III. is a cross section of several bottom plates, when assembled, ready for the top portion to be attachedthereto. Fig. IV. is a detailed top view of one of the sections of bottom.

The pipe may be constructed of any suitable metal and the top may be either plain or corrugated, the general form of the culvert being the same in either case but for the purpose of illustration Figs. I and II show the top portion made of corrugated metal and the bottom of plain metal.

Bottom B as shown in Figs. III and IV has a flange C along each side. These flanges may be of any desired height but that of two inches will probably be suflicient. At D flange G is offset as shown in Fig. IV and this for the reason that another section of bottom may fit therein and the two be bolted or riveted together at points G and F, this method making the inside of flanges C C perfectly straight and without projections; or projections on outside of flanges C C may also be avoided if flanges C C be cut 0E at points I) D. Bottom B also has a shoulder Specification of Letters Patent.

or offset along line E thus giving the inside of the bottom a perfectly smooth surface as shown in Fig. III, the two sections of bottom B being riveted or bolted at F F. If desired, more rivets or bolts may be used between points F F, thusmaking joints of bottom sections B B tighter and stronger.

Top A is of a general semi-cylindrical or circular shape as shown in Figs. I and II and the bottom edges thereof H H are cut or made smooth and straight and rest upon bottom B as shown and are secured to flanges C C at points G G by means of bolts or rivets and at as many other points along said flanges G C as may be deemed necessary. The lower edges of top A being inside of flanges O C and bolted to same, it is impossible for the top A to spread or contract when pressure is brought to bear thereon by filling material. Top A may be composed of as many sections as desired joined as shown in Fig. I by rivets or bolts at points I but this joint need not be placed or disposed directly over the joints of bottom plates B but may be so placed or disposed that the joints of the top A and the joints, of the bottom B will be broken or staggered thus giving the pipe greater strength.

Ordinarily water will flow through the culvert in a direction from J to K as shown in Fig. III but may flow either way and bottom joints at line E may be made water tight by the use of a greater number of bolts or rivets.

The culvert having a flat bottom, it is a very easy matter to prepare a suitable bed on which to place the same and, when in place, it is also very easy to properly tamp filling material about and over the same, there being no pockets or points where tamping is not possible. The joint in bottoms B B at line E tends to stiffen the same and give to the bottom of the culvert greater strength. Offset E may be on the inside of the botton B if a corresponding portion of lower edges H H be removed. If metal used is of the thin sheet variety the offsets I) and E may be dispensed with as the natural spring of the metal will take their place and the thickness thereof will be so small as not to interfere with .the proper assembling and use of the culvert. If corrugated metal is used to form the top section as is shown in Figs. I and II, at the point where top A adjoins top edges of flanges C C, regular openings corresponding to the corrugations will appear between flanges C O and top A but these will be in no way detrimental as they'will fill with dirt when pipe is tamped into position and this dirt will have a tendency to make joint at point H water tight.

The drawings show sections of top and bottom made in lengths of about two feet but they may be made of any desired length.

The use of the flat bottom gives to this culvert carrying capacity much greater than that of a round pipe, gives great stability and the general shape is such that it will carry a great load without displacement.

My claims are as follows: v

1. A culvert comprising a series of lower sections each of plate form having up-standing side flanges with lateral offsets at one end and also having between said offsets a depressed flange atone end so arranged that the opposite end of said base will engage the depressed end flange of an adjacent section when placed in position and the lateral ofisets in the adjacent base, means for rigidly securing the base sections together, a series of top sections formed of corrugated metal the lower edges thereof designed to engage the inner sides of the rip-standing flanges of the base and so arranged that the ends of the corrugated top sections will overlapone corrugation of the adjacent section, and means for securing the top sections in position relative to the adjacent top section and to the base in such a way that the upper portions of the base of the sections of bases will be substantially in line throughout the entire length of the completely formed culvert and a smooth bottom formed thereby, said side flanges of the different sections also being in line so that the sides of the various base sections will be substantially in alinement with each other to receive the upper sections when placed in position.

2. In a. culvert, a lower section of plate form having up-turned side flanges with lateral offsets at one end and a depressed flange between said offsets designed to receive the opposite end of a mating section and so constructed that when the mating end of the opposite section is placed upon said depressed end flange and between said lateral offsets the upper portions of the bot toms of the two sections will be substantially in alinement with each other as well as the inner surfaces of the up-turned side flanges. and curved corrugated top sections designed to be secured together at their adjacent ends and also secured to the up-turned flanges of the bases.
