SUPERSTRUCTURE OF ELEVATED RAILWAYS.

BFECIFICATION forming part of Letters Patent No. 318,213, dated May 19,1885.

Application filed Ortobcr 8, 1883. (No model.)

To an whom itmay concern:

Be it known that I, WILLIAM F. SHERMAN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Superstructuresfor Elevated Railways; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide an improved construction in tracksupporting structures for elevated railways; and it consists in the matters hereinafter described, and pointed out in the claims.

The track-supporting structure illustrated in the accompanying drawings as embodying my invention is more particularly intended for that class of elevated railways having suspended cars, or cars in which the supporting- Wheels project beyond the sides of the carbody and are placed at or near the top of the car, and in which the portion thereof in which the passengers or commodities to be carried are placed hangs below the track-rails.

In the accompanying drawings, Figure 1 is a side view of a portion of elevated trackstructure, including a truss for supporting the tracks over an intersecting street or road, constructed as proposed by my invention.

Fig. 2 is a vertical transverse section taken upon lineman of Fig. 1. Fig. 3 is a fragmentary view showing a portion of the longitudinal track-stringers and of the truss shown in Fig. 1. Fig. 4 is a detail perspective view of the upper end of one of the vertical supporting-posts of the track-structure and parts connected therewith. Fig. 5 is a detail sectional view taken upon line a: w of Fig. 2. Fig. 6 is a detail sectional plan view of the two adjacent track-supporting stringers at the center of the structure, taken upon liney y of Fig. 2. Fig. 7 is a detail section taken upon line as w of Fig. 6. Fig. 8 is a detail crosssection of the track and track-supporting stringers. Fig. 9 is a similar section of a modified form of the same. Fig. 10 is a detail vertical section taken upon line 2 z of Fig. 2.. Fig. 11 is a detail vertical section taken upon line 00 x of Fig. 3. Fig. 12 is a detail vertical section taken upon line 3/ y of Fig. 3. Fig. 13 is a detail horizontal section taken upon line zz of Fig. 3. Fig. 14 is a detail vertical section taken upon line 00 w of Fig. 3. Fig. 15 is a detail horizontal section taken upon line y y of Fig. 1. Fig. 16 is a detail sectional view taken upon line 3 1/ of Fig. 3.

A A are vertical posts or uprights, by which the several portions of the structure are supported from the ground, and B and B are longitudinal girders or stringers which are supported from the said posts A, and upon which the traclcrails O are placed.

0 is a car adapted for use upon the structure shown, which is provided with supporting-wheels c, secured to axles mounted in bearings supported upon the frame of the car at its top, the body of said car being arranged to hang between the rails and partially below them.

The structure shown in the accompanying drawings is arranged to support a doubletrack road, four track-rails, (Laud longitudinal stringers for supporting them being used, the stringers B, which are located at the outside of the track-structure, being supported from the posts A, and the two adjacent stringers B, at the center thereof, being upheld by means of transverse trusses supported at their ends upon the posts A. The said trusses, as shown and as preferably constructed, consist of two inclined struts, D, which are connected at their outer and lower ends by horizontal tension-members or tie-beams E, and which are joined at their upper ends and connected at their point of juncture with suspension-rods F, to the lower ends of which the said stringers B are secured. 1

The trusses formed by the struts D and beams E, as above described, form a series of cross-braces between the upper ends of the posts A, above the track-rails, and saidposts are also connected by girts G, which are located below the track-rails and a sufficient distance below the beams E to permit the passage of the cars traveling upon said rails be tween said girts and beams. In the trackstructurelshown the stringers Bare placed near the top of the posts A, and said posts, in addition to being braced longitudinally by the said stringers B, are connected by girts H, preferably placed in the same horizontal plane with the :girts G. The upper ends of the struts D, at their meeting-points, are also joined by longitudinal girts I, preferably consisting of angle-beams, which are placed with their salient angles upward and attached at their ends to the ends of the said struts by rivets or bolts. 1

The intermediate stringers, B, are upheld, as above described, by means of tension-rods F from the truss composed of the struts D and tie-beams E, and in order to support said stringers rigidly in position and to prevent lateral motion therein they are connected with the said tie-beams by means of vertical beams or struts K, and with the girts G, which are below them, by means of similar beams, J.

Additional rigidity is also given to the structure by means of struts or beams L, located between the upper ends of the struts D and the center of the tie-beams E, and secured at their ends to said struts and beams.

' As an improved construction in the longitudinal track-supportin g girders B and B, said girders, as shown more clearly in Fig. 8, con-,

sist of metal channel-beams B and wooden beams or stringers B which are fitted into the hollow interior of said beams, and are secured thereto by bolts or otherwise. The said channel-beams B are secured upon the posts A of the supporting structure with their web portions 1; in a vertical plane,'and their the suspension-rods F, with the flanges of the channel-beams B and the projecting portions.

of the timbers 13'' toward the center of the tracks, so that thetrack-rails O are supported upon the said timbers adjacent to the inner,

faces of the stringers.

An important advantage of the construction described is that the timber filling to the beam upon which the track-rails rest forms a cushion for said rails, and serves to decrease the jar in the structure and cars passing over it, and

thereby lessen greatly the wear and tear both upon the said structure and the rolling-stock. The wooden timbers also afford a convenient means of attaching the rails in place, and by the construction shown, in which the rails are located near the inner edges of the stringers, the side of the car may be placed near the rails at either side thereof, and the support ing-wheels may therefore be placed nearer together, and the entire structure made of less width than would otherwise be necessary.

The construction in the stringers above described also provides a convenient means of securing a second or auxiliary rail (indicated by C to the lower edge of the stringer. The auxiliary rail mentioned is preferably secured to the lower projecting edge of the timber B Verticallybeneath the rail 0, and is engaged by guard or safety wheels 0 upon the car, so as to prevent the possibility of accidental derailment thereof.

In Fig. 9 a modified form of the stringer is shown, in which the metal beam has a lower flange only, which is placed under the wooden filling-timber. In this case the timber performs the same function in acting as a cushion for the rail, as before described, and the rail may be placed at any point desired upon the upper surface of the timber.

The compound beam or stringer described may be used otherwise than in elevated roads as, for instance, for supporting the track-rails in surface roads over openings of moderate span.

As a preferable means of securing the compound beam B to the vertical posts A, when the latter are in the form of channel-beams, as shown, the web portion a of said beams is placed outwardly, and the inwardly-projecting flanges a thereofare provided with notches A, (shown more clearly in Fig. 4,) constructed to partially admit the channel-beam B The said beam 13 and the timber B are secured to the posts A by bolts a which are inserted horizontally through the channel-beam "and timber and" through the web of the post A, and are secured in place by nuts upon their ends. The notches A are preferably extended only partially through the flanges a, in order that the posts A may not be weakened by such notches to any considerable extent, and the space between the outer surface of the beam B and the inner face of the web a of the post Ais filled by a block, A, said block be ing held in place by means of the bolts a which pass through it, as shown.

In order to prevent the said beams B from resting at their lower portions directly upon the edges of the side flanges a of the notches A, a short piece or bearing-block, A preferably of metal, is interspersed between thelower margins of the said notch and the lower edge of said beam, said block preferably extending some distance at either side of the posts, as shown more clearly in Figs. 3, 10, and 11. Additional strength may be givento the parts by inserting between the flanges a a cross-piece, a having downturned ends which are riveted to the said flanges, and the upper portions of which are flush with the lower edges of the notches A, so as to afford an extended bearing for the said piece A, as shown more clearly in the detail sections, Figs. 10 and 11.

The compound stringers B, which support the two inner track-rails, and which are upheld by the suspension-rods F, as, above de-;

scribed, are preferably connected to the said rods byuneans of cross-bars F, arranged transversely beneath the said stringers, and

provided with central apertures, through which thelower ends of the rods are passed, and secured .by means of heads or nuts f. Saidstringers B are placed a short distance apart, so as to permit the rod F to pass between them, and a series of blocks, F are preferably ill- 1 terposed between said stringers at short in tervals, bolts f being; inserted horizontally through the said stringers and the blocks F soas to hold them"rigidlytogether,* Blocks F are also, as 5 shown; placed 'fbetween the stringers at the point of intersection of the suspension-rods F therewith, said rods preferably passing through a central apertureinj said blocks, and the blocks being securedbyf girts G by means of angle-plates j and 3' riveted to said channel-beams and to the said stringers and girts, respectively.

The struts K are, as shown in Fig. 6, constructed in a manner similar to the struts J said struts K being composed of two channelbeams, it, placed with the edges of their flanges together around thesuspension-rod F, and se cured at theirlower ends to the channel-bean1s B of the inner girders-by means of anglepieces which are, as shown, riveted to the said channeLbeams and secured to the stringers by bolts K passingvertically through said angle-plates; and stringers and through the angle-platesjt The'said beams k may be attached together intermediatelyof their ends by horizontal bolts K as shown, and to the tie-beams E by meansof ,angle-plateslc, or otherwise. The beams L are, as shown, constructed aridsecured at their ends in a man- 'ner siinilarto that of the girts K, as shown;

but such struts may be constructed in any other desired or preferred manner.

The struts D, forming part of the trusses by which the stringers B are supported, preferably consist of channel beams, which are placed with their web portions d upward, and the tie-beams E of said truss may also consist of channel-beams which are placed, as shown, with their flanges upward, and are connected at their ends with the lower ends of the struts D by means of rivets or bolts inserted through the overlapping flanges of the said tie beams and struts, the tie-beam being made narrower than thestruts, so that the flanges of the former fit between those of the latter, as illustrated inFig.4.@ 1

As a preferable construction in the joint or end. An improved construction in atruss for connection between the postsA and the ends of the struts D and tie-beamsE, the'said beams are made narrower than the said posts,iso that their ends may be inserted between the flanges a said'cross-plates cflare, as shown,provided lwith downturned ends which'are riveted orj bolted to the side flanges of the posts, and the "struts D and tie beams gE are secured to the posts by means of vertical bolts d passing through said cross-pieces a andthe ends of The struts D the parts D and E,'as shown. shown in the drawings are secured together at their upper ends bybeingbolted to the longitudinal angle-beams I, the suspension YrodFpassing through said angle beam and.

being provided with a nut,f, upon its upper supporting the stringers B and B over intersecting streets or roadways is illustrated in the drawings, Figs. 1 and 3. This truss consists, essentially, of a horizontal member or tiebeam, M, placed below and parallel with the outer stringer, B, of the track-structure,

inclined struts N. extending from. the bolts of the tie-beam M to a point over the center thereof, a vertical suspension-rod, P,s'ecur.ed at its upper end to said struts and at its lower 1 end to the tie-beam, one or more vertical posts,

as A connected with the said :tie-bear'n and stringer and with the struts N and adiagonal strut, 0, placed between the said posts.

of the latter, and cross-plates Zzare secured. *between the said flanges a thereof a-short dis-' tance below their. upper ends, [upon which plates the said tie-beams and struts rest. The.

1 i As illustrated in the drawings, the'post A is located at the center of the truss and rests at its lower end upon and; is secured to the tie-beam M at the point at which said beam is attached to the suspension-rod P, said post at its point of connectionwith the tie-beam M, and intersect the struts N at a point midway betweenthe "ertical center post, A, and the end of the tie-beam, the vertical posts A being located at thelpoints of intersection of the struts O and N and secured to said struts, 1 the tie-beam, and the stringers B. The posts A and A are preferably placed at the same distance apartas the postsfA, and are con nected with and support the track-stringers B in a manner similar to the said posts. Said posts A and A? are also'extended above said stringers and are connected with and support the transverse trusses, before described, by which the center track-stringers, B, are sup ported. Inasmuch as the post A does not form a member of the truss proper, such post may be dispensed with, the posts A being, in case the post A is omitted,disposed at proper distances apart to properly sustain the track-stringer and the transverse trusses of the structure. i

The tie-beam M may be supported at its ends upon the vertical posts A of the track structure which are adjacent to the opening spanned by said beam; or, as shown in the drawings, and preferably constructed, additional posts M are bolted to the sides of the posts A adjacent to the said opening, upon the tops of which the ends of the tiebeam M rest.

The connections between the lower ends of the struts N, the tie-beam M, and the vertical posts M, as shown in the drawings, Figs. 3 and 12, are constructed as follows: m, is secured to the tie-beam M at eachend thereof, against which the lower ends of the struts abut, said blocks being held in place by vertical bolts m and m passing through said blocks and beam. The posts M preferably consist,as shown, ofchannel-beams placed with theedges of their flanges against the sides of the posts A, and between the flanges of said posts M at the upper ends thereof are placed crosspieces m which are-riveted to the inner faces of ,the flanges at their ends, and are provided the posts .M and the tie-beam M, as shown,

and the space between the flanges of the said beam M near its ends may be filled by a block of wood similar to that indicated at N, Figs-.-

-10 and 16, in order to prevent the lateral strain upon the said beam fromcrushing the flanges; or, as shown in the drawings, metal plates m may be inserted between the edges of the flanges with the same result, said plates being preferably bent inwardly-and secured to the web of the beam by rivets or bolts,'.in the manner illustrated in connection with similar plates, of, at the center of said beam in Fig. 13.

. The struts N preferably consist of channelbeams having their web portions it placed vertically and toward the inside of the structure, and their flanges n projecting outwardly. Said struts are held in place at their lower ends by means of vertical bolts n, which pass through the said struts near their ends, and through the tie beam M and plate M, as shown. The upper ends of the struts N pass through notches cut in the flangesof the posts A, and are constructed to abut against each other, a block, N, being placed-over the upper meeting ends of the struts,through a central aperture, in which block the upper end of the rod P is inserted, saidrodbeing provided with a head or nut, 1?, upon its end above said plate. The ends of the struts N. may be secured to the posts A, as shown, by means of angle-plates a, bolted to said strut and posts, or in any other desired or preferred manner.

. The stringer B, as shown in Fig. 3, is immediately above and rests upon the block N; but

A block,

of the struts, as shown inFigs. 1-1 and-16, and

in dotted lines in Fig. 3. The said struts are preferably secured to -the-.. posts:Ai by i mea'ns oflhorizontal bol s n. passing-through the web; 1 A

portion of gSiiiCli1iIiliii N;, the:-fllling N and the web portion of'th'e post A, .as shown.-;;

The struts O preferablyv consist of channelbeams. placed with their flanges projecting in: wardly, said struts being attached at their upper, ends to thepost A at the points of intersection of the struts N therewith, by'having their web portions lapped over the said parts and secured thereto by bolts n, the flanges of said struts being cut away at the ends thereof and arranged to abut against the sides ofthe said posts. The lower ends of the struts O are, as shown, secured to the post A by means of bolts 0 passing through said post and the web portion of the struts, the flanges thereof being cut away, so as to abut against said post, and the said web portions being arranged to overlap the posts and abut togetherat their ends, as shown. The parts A andA may be secured to the tie-beam hf in any desired or preferred manner;-but, as shown in the draw ings, Figs. 13 and 14,, the flanges of the posts A are cut away and the ends of said flanges rest upon theti e-beani,the web portion of said posts being arranged to overlap the beam, and being secured thereto by bolts m", as shown. Asuitablefilling-piecemt, is preferably placed between the edges of the flanges of the beam A, and a filling-piece, m is placed between the flanges of the tie-beam M, in order to distribute the transverse strain of the suspensionrod 1? equally upon said flanges. The posts A are, as shown, connected at theirlower ends to the beamM in a manner similar to that described in connection with the posts A.

The construction above described is intended for trusses of moderate span,and in longer or shorter trusses the number of vertical posts and intermediate struts is increased or diminished as found necessary.

The post A being attached to the struts N and the tie-beam M, and by, making the fast-'- ening devices of sufficient strength, said post itself may form the vertical tension member of the truss in place of the rod Rand said rod described is that the vertical posts A* and A which form the supporting-posts for the trackstringers and for the transverse trusses before described, are attached to and form part of the truss, and the several members of the truss and the track-supporting structure above it being rigidly connected together, a firm and rigid structure is formed, in which great strength is obtained with the use of a comparatively small quantity of material.

An advantage is gained in the construction by which the flanges of the struts N are arranged to abut against the posts A for the reason that the said posts being secured both to the stringer and tie-beam tend to prevent any movement of the strut, so that said posts would have to yield or break before any considerable longitudinal movement in said strut could take place under the end pressure thereon, and considerable additional strength is thereby given the structure.

It will be observed that the tie-beams E over the tracks form a favorable means for the support for electric-conducting wires either for supplying electricity to a motor upon the car or for telegraphic or telephonic use. As shown in the drawings, bars R are secured between the flanges of the tie-beams E, upon which suitable insulators, m, are placed for supporting telegraph or telephone wires S. The proximity of the top of the car which is sup ported upon the track to the said tie-beams.

also furnishes a convenient means of access to the wires in placing them in position and in making repairs.
