Specification of Letters Patent.
Patented May 7 1907.
I Original application filed May 17,1962, Serial No. 107,812; Divided and this application filed July 25, 1904- SeriaI'NO. 2l7,93( 3.
To all whom it may concern: p
. Be it known that I, DANIEL B. LUTEN, a citizen of, the United States, residing at Indianapolis,' in the county of Marion and State of Indiana, have invented certain newand useful Improvements in Arch Structures,
"of which the following is a full, clear, concise,
and exact description, reference being had to the accompanying drawings, forming a part of this application.
This invention relates to improvements in arch structures of--that class which are commonly designed to serve as bridges or viaducts across streams, roadways,ra'vines, etc.,
and which are usually constructed of concrete,
stone, brick, cement, mortar and other materials; and the invention has for its gerieral object to provide an improved arch structure for this and analogous purposes characterized by increased strength and capacity to resist the strains to which the same is subjected.-
More particularly my invention relates to means for strengthening the railings-or spandrels 'of the arch or bridge, and especially of arches or bridges constructed of concrete and like material.
The present application constitutes a divif sion ofmy application filed on the 17th. day of May, 1902, Serial No. 107,812.
In the accompanying drawing, I have illus .tratedan arch or bridge of the type referred to having a railing reinforced and strengthened in accordance with the present inven spandrel wall or railing, provided with reinforcing, or strengthening means; and, Fi 2 is a central cross sectional view throug aportion' of the arch shown in Fi 1.
ments being joined. by the avein'ent 27, uiider the bed of the stream an preferably of con crete or the same material as the crown and abutments. The bed of the stream is shown at 30. The spandrel walls 23 or railings as they are sometimes termed, serve to confine the earth covering of the arch, and to strengthen the structure as a whole. Owing to the crackin that may result in such s'pandrel walls or rai ings by [changes in temperature or unequal loa other causes, I provide reinforcing members unequal loadings and other causes. rods 24 thus occur near each face of the spam In these figures, the arch is s own consisting-of the crown or'ring- 22 resting iiponthe abutments 29, the lower ends'of the abut ings applied to the arch or by;
other sections capable of resisting tension may be employed. I
The rods indicated in Fi 1 by the dotted line 24 are embedded int e spandrel walls 53 and are so disposed ,as to be low at the crown and high at the ends.
rods may occur in the positions indicated in Fig. 2 ,and any desired number of thcmmay be employed. Other rods such as -25 arepreferably carried straight across the top. of the wall railing and these are preferably brought down at the ends of the walls to the base of the structure, where they may be an chored as shown at 26 at the right hand on of the arch 0 Fig. 1 or they may be carried across the bo tom of the structure through the pavement 27 as indicated at 28. These rods effectually and primarily resist the cracking that'might be induced in the spandrel Walls by the changes in teniperatuil'p T drel, and together with the rods 25 form .a reinforcement or strengthening medium 'at both the top and bottom of the same, since the rods 25 pass near the upper surface. The
anchoring of the rods 25 near the base as in- 'dicated at 26 or in fact by tprni'ng the rods and'carrying .thein .across through the pavement, form a means for reinforcing the spandrel wall on its. back surface, and, thearch structure as a whole is thus cantalivered on itsabutment by theembedded reinforcingmembers thus provided. The rods thus shown and-described are not confined to the s 'ecific location or arrangement thus s ecid, butmaybe otherwise situated wit out departing from the spirit or scope ofthe pres ent invention. 4 Iclaim: 1. An arch having a s andrel wall, and suspension rods passin t rough said Well, sai rofls being low at t e center and high at the ends and continuing down into the abut mentsfi and anchors therefor, substantially as described.
2. An arch having a spandrel wallfsuspension rods in said wall lu' 'h at the ends and gofo preferably in the form of tension rods, though. low at the center, and other rods in the said no .wall extending straight sion rods in said wall low at the center and high at-the ends and passing down through the abutments and across the bed of the stream, a pavement covering said rods a'cross the-stream, and other rods in the "said wall extending straight through the same,isubstantially as described.
5. An arch 'having a spandrel or railing of concrete or similar material reinforced with longitudinal members near both faces.
6. An arch or bridge having a spandrel or railin of concrete or forced at top and bottom and atboth faces.
7. A bridge spandrel', railing or-retainin wall of concrete with rods or bars embedde near the stream and roadway surfaces thereof.
8. A bridge spandrel, railing or retaining' wall of concrete or similar material, with. lon- I rods 1 gitudinal rods or bars embedded near each w surface.
,9. An arch having a spandrel wall With ingdepressed at the center and near the upper surfa e at the ends .of the spandrel.
10. A concrete spandrel --wall or railing with tension members embedded and passing near the upper surface at the ends and near the intrados at the middle of the span.
11. A concrete spandrel for a bridge with tensionimembers embedded and other ten sion members across the bed of the stream.v
12. A bridge spandrel of concrete or like material with reinforcements extending across the span'both aboveand below the Waterway.
13. A concrete bridge with abutments tied together below the springing and above the waterway by tension members embedded in the spandrel.
14. An arch or bridge having a spa'ndrel wall or railing with reinforcin members embedded highatthe ends and ow at the center. I, I
15. A bridge spandrel of concrete or. similar material with a tension member embedded passing continuously through all the re. gions of tension. 4
similar material rein- 'gitudinal tension or bars embedded, said rods or bars be-' 16. A concrete bridge having a concrete 'spandrel extended back of the abutments rial having a reinforced spandrel or; girder extending across the abutment or pier, and cantalivered on the abutment or p er, wlth tension members extending across the abut- 'ment or pier near the upper surface of the spandrel or girder. 18.111 a concrete bridge a roadway between irders of concrete reinforced with rods or' are extending continuously-through' all, theregions of tension and of shear.
19. A ridge having a roadway between spandrels or girders of concrete or similar nia-' terial, withtei'ision members embedded near their. lower surfaces, said tension members having a plurality of shear members extending upward and inclined toward the ends of the spandrels or girders. V 20. A bridge consisting of a roadway of concrete'between concrete girders or railings reinforcedwith tension members near lower surface and extending upward toward the ends of the girder or railing.
21. A bridge consisting of railings or g1rders of concrete or'similar material projecting above the roadway and reinforced with 1011* members near the lower surface ofisaid railings or girders, said ten I 1..

22. In a concrete or similar bridge, a road way-between lrders reinforced with rods or bars embedde 'continuously through theregions oftension and of shear, and other rods or bars embedded in the compression regions.
23. A bridge having a road'wa between spandrels or g1rders of concrete or similar material with tension members embedded near their lower surfaces,'. said tension members having a pluralityof shear members extendbers'em'bedded near the upper surfaces of the spandrels or girders and over the abutment or 1er.'-.'
