Specification of Letters Patent.

Application filed April 21, 1911. Serial No. 622,519.

To all whoin it may concern:

Be 1t known that I, ALBERT LAURITZEN, a

citizen of the United States, residing at Charlotte, in the county of.Eat'on and State of Michigan, have invented a new and useful Culvert, of which the'following is a specifi one object of this invention to pro- Another object of the inventionis to pro-- vide novel means for interlocking the sideforming members of the culvert.

With the foregoing and other objects in .view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed-without departing from the spirit of the invention.

v of the invention In In the drawings, Figure 1 shows one form perspective; Fig. 2 is a fragmental perspective showing certain portions of the culvert in proper relative positions, but separated and broken away; Fig. 3 is a perspective showing a modified form of side member for the culvert; Fig. 4 is a perspective showing a modified form of bottom member for the culvert; Fig. 5 is a frag a mod fied form mental perspective showing of side member for the culvert, adapted to cooperate with the structure depicted in'Fig.

v 3; Fig. 6 is a fragmental perspective of one .of the side-forming members of the culvert,

showing the means upon the member, where by the bottom of the culvert is prevented from becoming displaced; and Fig. 7 is a fragmental perspective showing a modified means for preventing a displacement of the bottomof the culvert.

.The culvert herein disclosed, consists of crown members 1 and 2, resting upon side members 3, the side members 3 resting upon a culvert, interlocking elements upon- Patented Sept. 19,1911.

supporting members 4, carried by base niembers 5, between which base members, the bots tom member 6 is interposed. It will be un derstood that the members 3 duplicated to any desired extent, over the showing of the drawings, so as to permit an enlargement in the size of the culvert. The

'members 3 and 4 will be referred to here-' inafter as the side-forming members. of the culvert, while the members 5 and 6 will'be referred to as the bottom-forming members" of the'culvert.

Noting particularly Fig. 2-, it will be seen that the crown member 1 is provided with an offset flange -7, defining a shoulder 8, there being a lug 9 located in the angle defined by the members-7 and 8, the lug 9 being multiplied to any desired extent. These lugs 9 are adapted to register in notches 10, formed.

in the upper edge of the crown member 2. The interlocking engagement between the elements 9 and 10, prevents relative longitudinal movement between the members 1 and 2.

Referring to the supporting member 4, and noting particularly Figs. 2 and 6, it will and 6 may be be seen that, at its lower edge, the member 4 Y is equipped withan offset flange 11, defining a shoulder 12 in the member 4. Projecting inwardly from the lower edge of the flange 11, is an integrally formed finger 14, there being an upright lug 15, united with the finger 14, and fitting into the angle formed by the shoulder 12 and the flange 11. This lug 15 is multipliedto any desired extent, and is adapted to register in a notch 16 formed in the edge of the base member 5,

the base member 5 being supported by the inwardly projecting finger 14.

Referring particularly to the engagement between the. crown member 2 and the side member 3, it will be seen, noting particularly Fig. 2, that the crown member 21s provided,

alongits lower edge, with'a plurality of out-- standing primary tongues 17. These tongues 17 project beyond the lower edge of the member 2, and are spaced from the plane ofthe said member, the tongues 17 being fashioned integrally with the crown member 2. These tongues 17 are. adapted to overlap The crown member plurality of transverse reinforcingribs 21, certain of these ribs being extended upon the x member 3 is primary tongues 17, and upon thesecondary tongues 20, as clearly appearing in Fig. 2. The side member 3 is similarly equipped, with transverse reinforcing ribs 22, extended uponits tongues 18.

. Noting Fig.1 .it'will be seen that the side provided with longitudinal ribs 23 and24, the secondary tongues 25 of primary transverse reinforcing ribs with notches 'hereinbefore described, up

the member 3, springing away from the-rib 24, for interlocking engagement with the tongues 26 of the supporting member 4, the supporting member 4 being supplied with a longitudnal rib 27, and with 28, extended upon the tongues of the member 4, in the manner hereinbefore described.

It may be desirable, attimes,to form a three-piece culvert, and under such circumstances, the structure appearing in Figs. 3, 4 and 5 may be employed. Referring to Fig. 4, the bottom29 is provided in its edges 30. These notches 30 are the elements 15, on a side member 31, the side member 31 being equipped at its upper edge with the elements 7, 8 and 9. The other side member 32 employed in connection with the members 29 and 31, is equipped in its upper edge, with the notches 10, hereinbefore referred to, these notches 1O engaging with the lugs 9 upon the member 31, as will be readily understood.

Reverting nowto the structure shown in adapted -to engage with Figs. 1 and 2, it will beseen that the tongues 18, 17'or 26 are supplied with holes 33, adapted to register, respectively, with holes 34 in the crown member 2 and in the side member 3. Through these alined holes, bolts 35 or' the like maybe passed, to hold the structure assembled.

- In Fig. 7 of the drawings, an auxiliary means is shown, for preventing a dropping of the bottom of the culvert. bottom'is denoted by the numeral 36, the same having an outstanding tongue 37, adapted to register in-an opening 38 in the side member 39, the edge 40 of'the'bottom 36 registeringbeneath a rib 41, projecting inwardly, from the inner face of the side 20 upon the member 2.'

It will be noted that in all forms of the invention, the culvert forming members are strongly interlocked at their places of meeting, the flow line of the culvert, however, being unimpeded, none of the tongues, or the elements with which they engage, projecting inwardly, beyond the culvert.

At this point it may bi stated that the sevfashioned in any desired "lengths. The means forpreuenting a dropping of the bot tom of the culvert, and'the interlocking tongues upon the several portions of the to be confined to the specific structure shown, it being obvious that these upon culverts differing in a marked degree from those shown. The novel features embodied in this application, are adapted to be employed in the structures shown in my former Patents numbered 7 69,7 03-; 77 0,236; 746,112; and 770,237.

Having thus described the invention, what is claimed is 1. Ina device of the class described, a side-forming member having an inwardly projecting nger, provided with an upstanding 1 g, and a bottom-forming member adapted to rest upon the finger, and

having an opening to receive the lug.

2. In a device of the class described, a member having an oil-set flange defining a shoulder in said member, therebeing a lug fitting in the angle formed by the flange andthe shoulder, said member having a flange across the bottom of the lug; and a bottom member adapted to engage beneath flow surface of theelements may be employed 5 and 6, may be finger projecting from the the shoulder and to rest upon the finger,

the bottom member having an opening to receive the lug.

3. In a device of the class described, culoutstanding primary tongues upon their meeting edges, the tongues of each member overlapping the other member, there being upon one of said members, secondary tongues, beneath which certain of the primary tongues of the other member are adapted tofit.
