SPECIFICATION forming part of Letters Patent No. 476,720, dated June 7, 1892.
Application filed May 26, 1891. Serial No. 394,120. (No model.)
.To all, whom may concern:
Be it known that I, ELIPHALET L. ARNOLD, of Georgetown, in the county of lVilliamson and State of rlleXas, have invented a new7 and Improved Elevated Railway, of which the following is a full, clear, and exact description.
My invention relates to improvements in elevated railways; and the object of my invention is to produce an elevated-railway system which is comparatively cheap, which is absolutely safe, and in which the cars are arranged so that they ride very easily and can be readily adapted for both passenger and freight traihc.
To this end my invention consists of an elevated railway constructed substantially as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.
Figure 1 is a vertical cross-section through the railway and its connected parts. Fig. 2 is abrohen longitudinal section. Fig. 3 is a sectional plan. Fig. 4 is a detail cross-section showing the arrangement and construction of the switches used in the railway. Fig. 5 is a broken sectional plan of the switch. Fig. G is a vertical section on the line 6 6 in Fig. 4, showing in detail the mechanism for operating a sliding rail used in connection with the switch; and Fig. 7 is a broken detail plan view showing the manner in which the railway is constructed at a curve and showing, also, the provision for expansion and contraction.
The railway is supported on a series of vertical posts 10, which posts are made up in sections and are made hollow. Each post is provided with a strip 12, which extends spirally through it, and radiating from the lower portion of each post are arms 13, which are also hollow and which are adapted to be embedded in the earth, and it will thus be seen that the arms will prevent all lateral movement of the post. The post may be embedded in masonry, if desired, and after the posts are planted they are lled up with sand, gravel, or cement, thus making them absolutely rigid. Each post is provided at its upper end with a laterally-extending arm 14, which is adapted to support the track, and the arm li is made up of two parts 15 and 10, arranged one above the other, and the parts are united by diagonally-arranged strips 17, thus making them as solid as a single arm. The arm 14: is also provided with a brace 18, which extends from the outer portion of the arm downward to the post l0, and the arm and brace are pivotally mounted on the post, so as to provide for the expansion and contraction of the truss which carries the track, and which will be described below, and the swivel movement of the arm le also enables it to adapt itself to any curvature ot' the track. The arm 11 and brace 18 each rest upon a iianged collar 19, the collars 19 being arranged one above the other and held in position upon the post 10 by suitable keys 20, which are driven into slots in the post. These collars 19 have a circular exterior surface, and the arm 14 and brace 1S are provided with terminal sleeves 2l, which rest upon the collars 19, and thus atfordasubstantial bearing for the arm. The arm 14 supports at its outer endatruss 22, whichis preferably made of steel, and this truss is made continuous and formed of a series of short strips, which are firmly riveted together. The lower member 16 of the arm 14 is somewhat shorter than the upper member 15, and the upper portion of the truss 22 is provided with parallel and laterally-extending iianges 23 and 24, which embrace the lower member of the arm and which are pivoted to the arm by a king-bolt 25, which extends upward through the lower ange 24 and into the arm, as best shown in Fig. 1, and the bolt is held in place by means of a cleat 26, which is secured to the truss beneath the flange 2i and which engages a iiange on the head of the bolt 25. The upper member l5 of the arm 14 is curved slightly upward at its free end, as shown at 27, and is provided near the end with a concaved seat, which receives a ball 2S, which is formed centrally on a cross-bar 2D, and this cross-bar is provided at its ends with depending rods 30, which eX- tend downward on each side of the member 15 of the arm 14 and are curved slightlyoutward, so as to bring them into a position parallel with the side of the truss 22, and the rods 30 are widened and flattened at their lower ends, as shown at 3l, and are dovetailed into slideways 32, produced on one side of the truss,
TOO
s that the rods will form an additional support for the latter. It will thus be seen that the ball 2S and the socket in the arm 14 form a ball-bearing for the truss, and it will be noticed that as the truss is pivotally suspended from the tree end of the arm I4 and the arin is also arranged to swivel on the post the truss will be freely suspended, but will still be held in an absolutely secure position.
The truss 22 is provided near its lower end with a two-part base-plate 33, arranged on each side of the truss and having vertical flanges 54 on its outer edge, the base-plate being strengthened and supported by braces 35, extending from the outer sides of the base-plate to the lower edge ot` the truss. This baseplate forms a support for the track-rails 36, which are arranged near the outer edges of the plate and which are adapted to supporta car. The cars used in connection with this railway are suspended from trucks 37 and are adapted to run beneath the track. Each truck 37 is substantially like au ordinary railwaytruck and is provided with wheels 3S, which run upon the rails 3G and which are provided with wide flanges, so as to prevent derailment. It will be noticed that the elevation of the tracks enables the flanges of the wheels to be made et' any desired width, so that it will be impossible for the wheels to be forced from the track. The trucks 37 are also provided with a driving-wheel 3S, which is secured to one of the axles and which may be driven by a cable or by any suitable power, and in propelling the car any suitable driving mechanism may be employed, and it may be propelled by electricity, cables, steam, or even by horse-power. In the trucks 37 near the center, are vertically-movable boxes 3S), which are suspended upon springs and through which extend bolts 40, said bolts having their outer ends arranged to project beyond the sides of the truck, and these ends terminate in enlarged heads 4l, from which a car is suspended. Extending downward through these heads 4l are rods 42, which are connected at the bottom by cross-bars 43, and the cross-bars and rods thus form a hanger, which supports a ear 45, and in order that the car may be yieldingly supported springs 44 are introduced between the car-bottom and the cross-bars 43, and the joint effect of the springs 44 and the spring-supported slideboxes 3f) will be to enable the car to ride very easily. The rods 42 are at each end of the car, and they extend upward through yokes 46, which are arranged near the upper portion of the car and which serve to brace the hangers which support the car. rlhese yokes are connected by rods 47, and each rod 47 is provided near the ends with a socket 4S, the sockets being arranged to open in different directions. IVithin each socket is a spring 49, one end of which contacts with the closed end of the socket and the opposite end of which contacts with a collar 50 on the rod 4'7. It will thus be seen that when the car is suddenly stopped the inertia of the car will cause it to move forward slightly, and the springs 49 will have a buffer action and prevent any violent shock. The yokes 4G are also connected by cross-reds 5l, which serve to brace the same, said rods extending above the top of the car. In stopping the car any suitable brake mechanism may be employed, and, if desired, friction may be brought to bear upon the rails.
The track is covered throughout its entire length by a roof 52, which is supported by braces 53, extending from the center of the roof to the truss 22, and depending from the eaves of the roof are metallic curtains or shields 54, which are provided with elongated upper ends 55, which press against the under side of the roof, the shields being thus prevented froin blowing inward so as to obstruct the passage of a car.
The object of the roof and shields is to prevent the track from being obstructed by snow, ice, or frost, and also to shield it from the direct rays of the sun, and thus they prevent great expansion and contraction of the rails and of the truss which supports them.
In Fig I have shown the mannerin which the track is carried around a curve, and iu the same figure I also show the means for allowing the truss 22 to expand. In rounding a curve the base-plate 33 is dispensed with and braces 5C are secured to the lower sides of the truss and are adapted to support the rails 36. The truss may be easily bent to a desired curvature, and the braces will altord a secure support for the rails. To provide for expansion, the rails are halved together at certain points, as shown at 57 in Fig. 7, and a break is made in the truss, as shown at 5S, the adjacent ends of the truss being united by a sliding strip, so as to prevent their displacement.
In Figs. 4 to 6, inclusive, I have shown the switch mechanism. To provide for a switch, a cross-truss 5S is made to extend above the track and adjacent to posts IO, which are arranged opposite cach other and which support two track-sections, and the cross-truss 58 is provided with a central lateral bend, the bend describing the arc of a circle in which the movable track-section swings, and the truss 58"L is supported by suitable posts 59, extending from each end of it to the ground, and the posts are made substantially like the posts l0, already described. The swinging section of the track GO is supported from the cross-truss 58 and is hinged te the main track, said section having the truss 22,
yprovided with braces 61 at its upper edge z and on each side, and these braces are pivotally suspended from cross-heads G2 by means of links 63, and the cross-heads are held te slide in a track G4, which is arranged on one side of the truss 5S, as best shown in Figs. 4 and 6. The truss 22 of this swinging section G0 is also provided at its lower edge with braces 5G, which support the rails 3G in the manner already described. The cross-heads TOO IIO
62 are provided with cables G5, the cables being secured to opposite cross-heads, and the cables extend outward over suitable guidepulleys G6 and downward to a point adjacent to the ground, where they are wound upon drums secured to the posts 59, the drums having ratchet-wheels G7 at their outer ends, which ratchet-wheels are turned by handles 68 and pawls 60 and are prevented from turning back by pawls 70. The xed sections '7l and '72 of the main track are supported from posts l0 in the usual way at a point opposite the swinging section GO, and this section by moving it in the manner described may be made to align with either of these sections 7l or 72. The inner rails 36@ of the sections 7l and 72 are halved at the ends, as shown at 57a, and are held to slide longitudinally, so that when the swinging section GO is brought opposite one of these fixed sections a sliding rail 36 may be moved longitudinally, so that it will rest at one end upon one of the braces 5G, which support the rails of the sliding' section, and a safe joint will thus be made, so that a car may run in safety from one section to another. The sliding rails 3G are held in proper alignment by the guides 57 which are arranged. parallel with the rails and opposite the joints, and the rails are also provided with the usual chairs, as shown in Fig. 5. This sliding rail 36 is operated by a bell-crank lever 7i and its connections, the lever being pivoted on the side of the truss above the rail and having its lower arm held in engagement with a lug 75 on the rail, as best shown in Fig. G, and the bell-crank is held in a position to push the rail 36 back upon the fixed section by means of a spring 75, which is secured to the truss and presses upon the upper arm of the bell-crank. The upper arm of the bell-crank is provided with a cable 76, which extends upward and outward over guide-pulleys 77 and then downward to connect with a drum and ratchet substantially like that shown in Fig. t and described above. It will thus be seen that when the swinging section 60 is thrown to align with one of the fixed sections the rail 3G may be movedA by the lever mechanism above described so as to bring it into its proper position.
From the foregoing description it will be seen that the railway is perfectly safe and simple, an d, if desired, the cars may bebrought near enough to the ground so that they may be easily entered from the ground and freight may likewise be easily placed in them. I have shown the railway as adapted for passenger or freight traffic on a large scale; but, if desired, the entire mechanism maybe made light, and the cars may be propelled by horse or mule power.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl.
