SUSPENSEONHARCH.
Patented June 4, 1907.
. resident of Clay City, in the county of Clay and State of Indiana, have invented a new and Improved Concrete Steel Sus ension- Arch, of which the following is a fu l, clear,
and exact description.
. This invention has for its object to provide means adapted to enable concrete arches to be constructed with a much larger span than is practical at the present time, with less concrete and with a smaller rise.
Suc-h objects I accomplish by the moans illustrated in the accompanying drawings, in which drawings like characters of reference indicate like parts throughout the views, and in which Figure l is a longitudinal sectional elevation of an arch embodying my invention; and Fig. 2 is a transverse section of the saine taken on the line 2-2 of Fig. l.
As illustratcdin the drawings, cables lA are sup',':.-ortet l upon steel columns 2,"tl'1e" 'lendli' of which cables bei-ng' 'irnily anchored in any suitablemannen'preferably in beds 3 of con- ,creti lendent cables 4 are secured at their upper ends to the main cables, and carr transverse beams 5 secrcd to the lower ends of said cables. Rein-forcing bars 6 are arranged inl parallel series, curved longitudi 'na-lly and supported upon thetransverse.
beams An arch .ring of concrete is formed around the transverse beams 5 and reinforcingr bars 6, thereby embedding said bars and beams within the arch ring, and rein l'orci ng said ring larapcts 7 are formed on the arch ring and in closc the pendent cables 4 and main longitudinal cables l.
The steel columns 2 arc also preferably embedded with concrete walls fornicd inteffral with the concrete arch ring and its parapets. By incans of such construction thc arch manr bc Iliade. with a span of an) desired length and with a minimum amount of concrete and with the lcast possible rise.
'lhc metallic rcinforcingparts of my invention may be modified materially both in construction and arrangement. without depart.- ing' l'roni inv invention. 'lhus the ptnident cables 1 or main cables l may be made ol` strands or ol' links in the form of a! chain. l prcl'cr thc latter construction lor the reason that the concreto obtains a better ihold on the cables, and the cables exert a lifting force on the concrete, as well as on the cross beams 5. The reinforcing bars 6, moreover, may be made of flat iron twisted or corrugated bars, instead of round bar iron, as shown in the drawings.
It is obvious, moreover, that; the reinforcing bars 6 and transverse beams 5 may be used without the pendent cables el. In that case l prefer to arrange ythe transverse bars 5 above the longitudinal bar: 6 instead of below, as shown in the drawings. Such con struction is especially desirable where there are no longitudinal supporting cables or steel columns used,
Having thus described my invention, what l claim new and desire to secure by Letters Patent is:
l. An arch comprising concrete columns, an arch ring connected therewith, and parapets formed on the sides ol' said ring, metallic columns embedded within the concrete col umns, longitudinal metallic cables supported "o'fsa-id metallic columns and provided with pendent cables embedded in said parapcts,
and transverse bars connected with said pendent cables and embedded in said arch ring.
having an arch ring connected therewith, and parapets l'ormcd on the sides oll said ring, nietallie longitudinal cables cm'bcddcd in said parapets, metallic columns supporting the ends ot' said cables, pendent cables` secured to said main cables, a plurality of curved reinl'orcing rods, and a series olrtransvcrsc beams snpporting'said rods, all being cnibcddcd within the concrete columns, ring and parapcts. i
3. An arch con'iprising concrete columns, an arch ring and parapcts l'ormcd on said arch ring, in combination with curved mctallic longitudinal main cables and pendent cablcs .secured thereto embedded within said parapcts, und a plurality ol' longitudinal rods curved oppositcly to thc curwxturc ol' the main cables, and a scrics of transverse bars arranged below said reinforcingl bars and connected with said pendent cables. i 4. i\n arch comprising concrete columns, l rinpr and parapcts, in combination with mctnllicl columns embedded within said concrctc columns, longitudinal cables supported lon said metallic columns, cxtcnt'ling outward An arch comprising concrete columns.-

from said columns at their ends and curved transverse bers connected With said pendent x01 l between said columns, metallic hangers secables.
cured to seid main cables embedded Within In testimonyy whereof I hevesigned my said parapets, and a plurality of curved reinname to this specification in the presence of forcing bars embedded in said arch ring. two subscribing witnesses. l
. 5. A concrete arch 'having embedded EDGAR J. SCHAUWECKER- therein metallic longitudinal main cables, f Witnesses: y
pendent cables secured thereto, a plurality of B. M. DAWSON,
curved longitudinal rods, and e series of ARTHUR POORMAN.
