vill/1114?]A CHARLES FRANKLIN ALT, UF WARREN, PENNSYLl/ ANLL CULVERT.

T o all whomit may concern-.-

Be it known that I, CHARLES F, ALT, a citizen. ofthe United States, residing at VVai-ren, in the county of Narren and State of Pennsylvania, have invented. certain new l and useful Improvements in Culve rts, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in metal culverts for use beneath roadways and for analogous pur oses..

'l`he object of t ie invention is to provide a galvanized metal culvert which will be simple, strong and durable in construction, comparatively inexpensive to produce and to construct and exceedingly' durable and effective in use.

With the above and other objects in View, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter' fully described and claimed, and illustrated in the accompanyingr drawings, in which-- Figure 1 is a vertical cross section through a culvert constructed in accordance With t e invention; Fig. 2 is a view artly in side elevation and partly in vertica section taken on the plane indicated by the line :3f-2 in Fig. 1; and Fig. 3 is a detail transverse section through a slightly modified forni of the invention.

The improved culvert is formed from aV plurality of arch-shaped body sections 1L of corrugated galvanized metal arranged with their ad'acent ends overlapping and with their si e ed es resting upon flat metal stringers 2. he body sections 1 are substantially semi-circular shaped in cross section and they are `formed with transverse corrugations 3 which effectivelyV strengthen them. The endmost corrugation of each section overlaps the corresponding corrugation of the next adjacent section, as shown at 4, but in order to more effectively reinforce the joint one or more metal straps 4 may be secured by bolts, rivets or similar fastenin s 4b to the top or exterior surfaces of said en s of 'the sections, as clearly shown in Fig. 2.

The connecting or oint plate 4a is shaped to lit the two body sections and overla s the l)oint or scam, thereby greatlvstrengt lening the latter. The edges of thel body sectionsv 1 are effectively secured to the base formed by the stringers 2, by means` of suitable clips and bolts, rivets or similar fastenings. VSaid clips are here shown in the form of angle Specification of Letters Patent. g Application filed August 13, 1908. Serial No. 448,399.

'It will also be seen that owing to the shape Patented April 20, 1909.

nietal plates 5 arranged in staggered relation on both the inner and outer faces of the sections and securedto the latter and also to the stringers` by bolts 6. Instead of the angle clips or plates 5 I may employ angle metal bars to unite the body sections to the stringers. These anvle metal bars would extend continuously from end `to end of the culvert and would greatlystrengthen and reinforce the saine. 'l`he stringers extend longitudinally. throughout the length of the culvert and their abutting ends are united by a joint )late 7 arranged beneath thein and secure by certain of the bolts 6, as clearly shown in Fig. 2.

The stringers 2 may be merely ilat plates, as shown in Fig. 3, so that the bottom of the culvert will be formed b the earth upon or Within which it is located, but they are preferably made of angular sha )e in cross section, as shown in Fig. 1, so t at the edges of the body sections may be secured to their horizontal portions or flanges 8 and their inwardly or downwardly projecting anges 9 may be secured by bolts or similar fastenings 10 to metal bottom' sections 11. These stringer sections may be llat or curved transversely, as shown in Fig. 1, and they may also be either plain or corrugated. 'Vlie fas tening bolts 10 pass through the bottom seetions 11 and the flan fes 9 of the stringers but it Will be understoo that clips or other fastening'means ma be substituted and that any other fastenmgmeans other than the angle plates 5 may be employed for uniting the corrugated body sections to the stringersl or base. A

From the foregoing it will 'be seen that the invention l provides an exceedingly' simple culvert, the parts of which may be produced at a small cost and quickly and easily put together. It will be further noted that it will be exceedingly strong, rigid and durable.

of the several parts of theI culvert it may ie shipped to the point where it is to be used in knocked down condition with its parts nested or bundled and bolted together. ilaving thus described the invention what is claimed is:

l. A metal culvert comprising metal stringers, arch-shaped body sections having their edges resting upon said stringers and right angular metal clips. arranged u pon both the inner and outer faces of said body sections and each having one member vsecured to one of seid body sections and its other member secured to one of seid stringers.

2. A metal culvert comprising stringers, srch-shaped body sections corrugated trans- 1 versely end having their ends overlapping' and their edges resting upon er1-1d stringere,

and :ingle metal clips uniting seid sections to l the stringere.

3. A inetel culvert comprising' metal stringere, arch-shaped body sections having their edges resting upon seid stringers and fastening means uniting said sec-tions to the stringere.

4, A metal vculvert comprising metal stringers, arch-shaped body sections corrugated trensverselyend having their edges resting upon seid 4stringors end their ends overlapping, and angle metal plates uniting the body sections to the strin ers and arranged upon both the inner an outer feces of said body sections.

5. A metal culvert comprisingistringers,

arch-sh eped body sections having their edges said stringere.

7. A metal culvert comprising nietnl strinv'ers, arch-shaped body sections corru- Tated transversel f und heviinr their ends overlapping and their edges resting upon the stringere, joint plates extending over the joints and. united to the overlapping sections and fastenings the strngers.

In testimony whereof I hereunto nflix my signature in the presence of two Witnesses. CHARLES FRANKLIN All".
