Specication of Letters Patent. Patented Jan', 1918,
Application med July 1o, wie. serial nu. 108,275.
To all whom it may; concern: Be it known that l. LAURrrs W. Nnnsnn, i'citizen of the United Sintes, residing at IPontiac, in the county of Livingston und 5` State of Illinois, have invented a certain new and useful improvement in Culverts, 'of which the following is a specification.
My invention lrelaties to :in improved culvert construction in which cul vert sections of arch form may be iliade in quent'ty in the factory end shipped to the place where theculvert is to he umide, et which place they 4maybe essei'nliled to torni the (zonipleted culvert. The culvert sections nre referehly of U-shepe, although they muy lieve other conformetions. lfind thesesections are provided with reinforcing rods of iron or steel, some of which are secured in the "z'erids of the culvert sections 'when they are Zofmenufe'ctured. so that the portions of the 'tween the ends thus secured extend ie ends of the culvert sections to he g hv the concrete o the hed of the 'lien the latter is constructed. The ing here thus secured in the culvert s hold the ends thereof together to stron hen, the sections after they ere inadeand uring shipment of the seme. The ses i tions are preferably made from concrete. 30 My invention is shown in its preferred embodiment in the eccompenyirig drawings,
in Which- Fiure 1 shows one of the culvert sections 'in Si e elevation, Fig. Q-shows .the culvert section-in end elevation,
Figi: 3 shows portions of 'two of the culvert s c a sections 1n place in the completed culvert in side elevation, and
const ction shown in Fig. 3. Sim er .letters refer to similar parts throu 'hout the several views.
As hewn in Fi .i and 2,' each culvert section is preiereb y provided with elbody f rcing rods a of iron or steel extend .to :strengthen the section. These rods are prefyerebly continuous, although they may' be made in an desired mennen und form and l.given any esired arrangement. It is Vpref'- erable to V.employ also a. second set of reinforcing rods insidel of the 'rods-o, shown at ierred to, other reinforcin rods o are provided which have bent en extremely simple opera-tion Figj shows in end elevation the culvert b. In addition to the reiforcingrods resecured in the.
ends of the culvert'section, so that-the mid portions of the barst' eXte-Iidheyon'd and outside of the ends of the' culvert sr'ctionund serve to connect the end portions of' tiie sec tion together to strengthen the s'zilmefslo that after the sections are manufactured as' do scribed, they cannot readily be broken dun. ing handling or shipping. v l,
l-Vhen it is'desired to construct. a culvert from sections of the kind shown in Figs. l und 2, a. continuous hed of concrete B, as shown in Figs. 3 nudil, is first made which prf-.terribly is provided with longitudinal reinforcing rods d, end before the hed of concrete sets the sections A are put in place by Aforcing the extending portions of the reini Jorcin rods c into the still lastic upper sur, face o the hed and embe ding the end di the sections in the upper surface of .tlie"hed B with the side edges of the 4sections es close together es they rcan be brought. The concrete of the bed, of course, closes over the reinforcing rods c and When the bed is set, the result is e. strong reinforced concrete construction.' The joints between the sides of the sections may he filled, if desired, with thin cement-.so es to completely close them.
As e result of my construction, I am able to Ine-lie the culvert sections A in the factory in quantity, so that the\seetions may readily be hed and shipped to any location Where it is desired -to construct e culvert. Further more, the construction of the culvert is en since it requires only the laying of the concrete bed B of the culvert and no forms whatever are required .to ,comple-te the culvert construction, since 'the sections arereadily put in place in the culvert sections which may be manufactured in advenee, resdy for use 'in any quantity and locality. l l
W'hile )Chaire shown, lmy invention in the particular embodiment above described, I do not, however, limit myself to this exact construction, as Iinay lemploy any equivalent thereof knovvn' to the art at the time; of
- the liling of this application without-departin from the scope of the appended claims.
at I claim is:
1. As an article of'manufacture, a culvert sectionvcomprising concrete formed into a.
.U--shao""heving substantially parallel side but have also provided en im-- ion Walls and open on one side adjacent the ends of said sides, a relnforcing rod or rods havring their ends-bent at substantially right angles to the middle portion thereof andV having a portion ofsaid bent ends embedded y vin the concrete of the section, whereby said rod or rods extend across said open side at a distance from said ends, and a reinforcing rod or rods extending through, the concrete of the section substantially parallel to the edges 0f the section.
2. As an article of manufacture, a culvert section comprising concrete formed into a a distance from said ends.
The method of forming f'- enrert, con sist'ing in forming a envcretel Jl at the place where the Vculvert is ti, or enlistructed`y and placing upon the had previously completed (mit arch sections having I prfnjeetii'ig retain ers, said retainers being embedded in the concrete of the loed While the concrete el? the hed is still in plastic condition and before it has l 4. The method of forming a culvert, consisting in forming a concrete bed at the place where the vculvert is to be constructed, and
placing upon .the bed before the latter has' set unit arch sections having project-ing tie rods bet-Ween their lower ends so that the tie rods are en'ihedded in the concrete of the hed when the unit arch sections are placed in position.
