SKEW-ARCH.
Specification of Letters Patent. Application flld. May 13, 1911. Serial N0. 627,040.
Patented Sept. 26, 1911.
-To all whom itmaycon-cern:
Be it known thatI, Dinner. B. LUTEN, 'a
I citizen :of the United States,r esiding at Indianapolis, in thegcounty of Marion and State of Indiana, have-invented anew and useful Ii'nprovement 1n Skew-Arches, of
- :which the following is a specification 3 Fig. 2 is a My inventionrelates to improvements in a skew arches and has for its purpose to provide increased strength. and waterway of such structures without, added materials or increased-cost.
The invention is illustrated in the accompanylng drawings in which the same reference. characters describe like parts throughout the several views.
--Figure 1 is a longitudinal section of a skew arch taken on the line C D of Fig. 2. plan of a skew arch embodying my improvement, Fig. 3 is a vertical section-onthe line A B of Fig. 2, Fig. 4 is a vertical section at the crown parallelto the I axis of the arch an'd'to the section of Fig. 3',
' spondingly in A skew arch and Fig. 5 is a plan showing the axes of the arches.
exerts'greater thrust upon its abutments and piers ,3 at its obtuse angle 2 than at the acute angle 4. Hence itis desirable to provide greater strength in those portions of the.
arch where this greater thrust is exerted. I therefore thicken the arch ring in the obreduce its thickness correthe acute angle. section of Fig. 3 takenon'the line A B. shows a thicker arch ring at 5 than at 6. At the other end of the span as at 7 and 8 the reverse conditions would apply, 7 having the tuse angle and It is frequently desirable in such abridge to 'build multiple spans with different de-- grees of skew, the axis of each succeeding arch incliningmore and more with respect to the roadway. thickening the pier at one. end.-- Thus in Fig. 5 the axis E F of arch G is inclined to the roadway .and to the longitudinal axis of the bridge more than the axis H I- of the arch J The axes are each parallel respec- It has been customary in building reinsides inclined wit respect to of properlybonded materials Thus the corresponding [and reinforced with bers substantially normal to itsface.
This'is accomplished by my hand and forced skew arches to skew-the transverse reinforcement, placing it parallel to the axis of the arch. In my improvementtthese transverse members are placed substantiall at right angles with the roadway, d less of the degree of skew of the arch. Because of the thickness of the haunches at the obtuse angles these transverse-members are readily embedded although the in" trados of the arch may be much lower at one end of the member than at the other. The result is a structure well balanced and reinforced to resistthe eccentric stresses that occur in a skew arch.
1. A plurality of arches in straight al'inement but wit-h their axes inclined with respect toone another, and supported on a plurality of piers, each pier having its faces parallel respectively to the axes of the adacent arches. r
2. A plurality of skew arches supported on a plurality of i'ers, each pier having its each other. 3. A skew arch. and su ports therefor withobtuse and acute 'ang faces of the arch and the supports, said arch being of increased thickness at the obtuse angle and of decreased thickness at the acute ange. I
4-. A skew. arch of thickness. increasing longitudinally of one abutment and decreasing correspondingly along the op ositeabutment, and reinforced substantia ly at right angles to the longitudinal axis of the arch by embedded tension members inclined to both abutments.
5. An arch with parallel faces inclined to its axis and reinforced substantially normal to its faces byembedded tension members in- =clined to its'ax1s.:
a'face inclined to its axis embedded tension mom 6. An arch with In witness whereof, I have hereunto apt seal 7 at Indianapolis, Indiana, this eleventh day of May, A. D. one their sand nine hundred and eleven.
