OVERHEAD TRACK FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 452,201, dated May 12, 1891.

Application tiled December 16, 1890. Serial No. 374,924. (No model.)

To all whom t may concern:

Be it known that I, EwEL I-I. 'IHATOHER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Overhead Tracks for Railways, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to an overhead-railway system with means for the suspension of the cars that run on their surmounting` track; and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a top plan view of the overhead trackway, showing a curved track quarterturn in full lines and aterminal return-track in broken lines. Fig. II is an enlarged transverse detail view of the roof of the suspended car,thehanger pivotally secured thereto, the track-wheel mounted on the journal of said hanger, and the track-rail on which said wheel runs. Fig. III isa side elevation of the track on its elevating-posts, and shows the means of trussing and bracing the track, of suspending the car beneath said track, andthe alighting-platform with its brace attachment to one of said posts. Fig. IV is an enlarged vertical section taken on line IV IV, Fig. V, and shows a detail'of one of the truss-beams with one of the track-han gers therefrom,with a transverse view of the track-rail secured thereto. Fig. V is an enlarged vertical section taken on line Vv V, Fig. IV, and shows a like view, but longitudinal of the line of track-rail and transverse of the truss-beam. Fig. VI is a side View of one of the truss-beams, with a detail of the tops of the elevating-posts to which it is secured. Fig. VII is ahorizontal section taken on line VII VII, Fig. III, and shows the landing-platform and stairway; and Fig. VIII is an enlarged vertical section taken on line VIII VIII, Fig. III, and shows the collar-brace attacher-clips around the posts, with a detail of the brace-bars screw attached between the ,iianges of the clips.

Referring to the drawings, l represents the elevating-posts that carry the overhead track, which posts are preferably ot hollow-metal construction.

2 are the truss-beams, which may be cast or made of steel or other suitable metal, and

are constituted of upper and lower longitudinal sections of T-bars that are beveled at the corresponding inner edges of their terminal ends, at which ends they are secured to the posts, their joint ends 3 being seated and fastened by any suitable means in the slothousings I in the enlarged heads 5 at the top of the posts. The said truss-beams are constituted of the lower straight inverted- T-bar sections 6, the upper inclined T-bar sections 7, the center tie-straps S, that are secured below and above, respectively, to the sections 6 and 7 by the screw-bolts or rivets 9, the bevel-edge coupling-plates 10, which at the point ends of the 'truss-beam are secured to its sides at the terminal ends of the sections 6 and 7 of said beam by the screw bolts or rivets 11 and the cross-angling truss brace-rods l2, which are secured in series on each side of said truss-beam in respectively cross-angled positions to each other by screw bolts or rivets 13, which pass through the flanges let of said truss brace-rods and through the T-iianges l5 of the sections Gand '7 of the truss beam. The said truss beams reach across to the return track system, so as unitedly to brace the elevating-posts and the track-rai1s that are elevated thereby.

10 represents the foot-Hanges of the posts l, that are fast secured to them just above the ground-line, and which foot-anges brace the posts from tilting from the vertical position in which they are set.

17 represents the duplex trackhangers, whose saddles 1S are mounted on the trussbeams 2. The said hangers are preferably made of fiat bar-steel or wrought-iron, and immediately beneath said saddles and said truss-beams on each side ot the beam the fiat hanger-bars have quarter-twists 19, that bring the face ot' the hanger-bars in line with the track-rails 20, which said hangers carry in suspension. n

The hanger-bars near the point of their attachment to the rails have curved necks 2l, to secure more play for the traveler-wheels 22, that travel on the track-flanges 23 of said rails, and said wheels carry the cars in suspension, and beneath said curvature the perforated attachment foot-flanges 24 of the hangers again run on parallel lines with the IOO rails. The toes 25 of said loot-flanges of the hangers rest in contact with the foot-flange 2G of the rails 20, and the space between the parallel foot-llanges of the hangers and the pedestals 27 of the track-rails are stopped by the combined perforate iilling-blooks and lishplates 2S and in perforations 29 in said footilanges of the hangers, in said tish-plates, and in said pedestals of the rails the screw-bolts 30 are seated and screw-nuts 3l engage on said bolts to secure the attachment ci the rails. The said rails are ot equal length with that of the intervening spaces between the centers of the post and the fish-plate fillingblocks 2S, as they exercisethe combined functions of lling-blocks between the foot-flanges ot the hangers and ot' fish-plates, that splice the meeting ends of the rails. Their attachment. to said rails is still further re-enforced by the screw-bolts 32,which pass through and are seated in the perforaticns in said fishplates and in the meeting ends of the rails, and are there secured by the nuts 33.

34 represents binder-straps that surmount the saddles 1S of the duplex track-hangers 17, and which have pcrtorate flanges 35, in which and in registering perforations in the T- lianges of the upper T-bar sections ot the truss-beams screw-bolts 36 are seated and are secured 4in their seats by the screw-nuts 37, and thus the said Saddles and track-han gers are held from displacement.

3S represent truss-rods, whose hooks 30 engage in the eyelets 40 of the eyelet-lugs l1, which lugs are secured to the foot-flanges of the meeting ends of the rails by their integral angle-hooks 49, which are seated in the recessed spaces 43, that are provided by a slight foreshortening of the meeting end of said foot-flanges of the rails. The said lugs are further secured to said rails by the screwbolts et-l. Truss-blocks l5 are provided with recessed crosschannels 4G at their lower ends, in which cross-channels the truss-rods sit midway between post and post, the upper ends of said trussing-blocks being underseated against the foot-flanges oi the trackrails that surmount them. The rods are thus trussed midway of their length and form an under brace-support for the track-rails also midway ot their supported ends.

47 represent guy-braces that diverge from the posts on each side, angling upward tothe track-rails, the feet of which braces are secured between the flanges 4S ot' the semicircular collars t9 (that form clip attachments to the posts) by the screw-bolts 50, that are seated in the pertoratious 51 in the said flanges and in the feet of said braces and are there secured by screw-nuts 52. The flanges 53 at the heads of said braces are secured to the pedestals 27 of the track-rails by screwnntted bolts 54, which are seated in perforations in said head-ilangesof the braces and said pedestals of the rails, and are secured in their seats by their screw-nuts, that are attached thereto. Vhcn the track makes a sharp turn,

such as a right-angled turn, as shown in full lines in Fig. I, or makesa terminal-circuit turn, as shown in broken lines in said ligure, then counter truss-beams are placed in coupling connection with the ends of the last two pairs of truss-beams at :the turning-point, so as to make a truss-beam square; also, an additional cross-center truss-beam forms a span coupling-connection between the centers of said last two pairs of truss-beams, (see said Fig. 1,) and guy-braces 17, as already described, and alike secured, brace the trackrail at their turns, as they are braced all along the line, as described above, and as shown in Fie". I.

In the case of aright-angle turn the hanger that supports the outer-turn track may be saddled farther from the end of the crosscenter truss-beam, as shown in full lines in said ligure, and in the terminal turn the trackhanger may be saddled nearer to the end of said truss-beam, and the track-hangers tothe counter truss-beams may be saddled from the center of said beams, as shown in broken lines in said Fig. I. The aforesaid traveler-wheels, whose flanged peripherics 55 run on the traekrails 20, are mounted on the journals 5G, which journals are seated in the j ournal-bearings within the hubs 57 of said wheels, and said journals project from the shoulder-col lars 58, that surmount the pendent car-hangers 59. The suspensory pivot screw-bolts 60 are seated in the perforations Gl in the anglelugs 62 of said hangers inthe swell-collars 63, that surmount and are integral with the roof G4: of the car 65, and through and projecting beneath said roof. On the projecting screw ends of said pivot-bolts the screw-nuts G6 are engaged, and their screw attachment is reenforced by the jam-screw nuts G7 through the perforations GS, in which nuts and bolts the spring-keys 69 are inserted to securely lock said j ain-nuts. The car is supported from said traveler-wheels by two ot` said hangers, which, as they connect by pivot-bolts with the strong roof of said car, they have, respectively and relatively, pivotal adjustments that prevent the straining of the snspensory attachment while turning curves on the track.

70 represents the alighting-platform, whose l'loor 7l is supported around one of the elevating-posts l, at an equal height to that of the end platforms 72 of the cars, by the angle-braces 7 3, the tops of which braces are securely attached to said platform that surmounts them, and the perforated foot-flanges 7i of which braces are secured to and between the projecting flanges 75 of the clipcollar 7 G, that clamps said post by screw-nutted bolts 77, in the same manner as are the track-braces 47 to the flanges of their clipcollar 49, as shown in Fig. VIII.

7 8 represents a stairway for the ascent of passengers to and descent from said platform. 7 9 are the banisters of said stairway, and SO is the railing around the platform. Sl rcp- IOS IIO

resents the hinged gate that respectively closes the gateway 82 when the car is not in, for the safety of the passengers, and opens said gateway when the car arrives, for their passage to and from said car.

The operation of the device has been pointed out through the description of the parts, so that little is left that is necessary to say to throw any further light thereon. It will be seen, as shown in Fig. I, that all the supplemental parts required either for an angleturn of the track, as shown in full lines, or for a terminal loop, as shown in broken lines, (see said figure,) are three additional trussbeams and their attendant hangers and guybraces. No supplemental posts are required for either said angle-turn or loop.

It will be seen that this overhead railwaytrack occupies but a minimum of space on the ground surface of the streets, amounting only to the space occupied by the two lines of posts and the stairway to the alightingplatforms, which platforms themselves are elevated out of all obstructive interference.

I have shown the feet of the lateral guybraces 47 as secured by their clip attachments to the posts a short distance below the level of the track; but said clips and braces may be secured to said posts on a level with the track and will still be alike operative as lateral guys.
