TocrlZJ whom may concern Be it known that l, CHARLES E. PADGETT, citizen ofthe United States, residing at Buffalo, in the co`unty of Erie and State of New York, haveinvented certain neWand useful Improvements Elevated-Railway Systems; and l do hereby declare the following to be a full, clear, and exact description of the same, Whentaken in connection With the accompanyingv drawings, forming part of this specification.

This invention relates to systems of transportation in Which the cars are adapted Vto travel on Ways elevated above the Vsurface of the ground, the objects of the invention being to provide a simple and practical means ywhereby safe and rapid transportation may be effected both in urban and suburban localities, and with Which all danger incident to surface transportation vvillbe avoided and advantagessecured in thevvay of increased safety, due to the fact that provision is madevvhereby disastrous accidents, due to derailment and to storm conditions will be effectually overcome. Y

Referring to the accompanying dravv ings-f Figure l4 is a` side elevation of a section. of an elevated structure embodying the present improvements, portions being broken. away andL one end of a. car or vehicle shown in outline.

Fig'. 2 is a sectional elevation in a plane at right angles to Fig. d

Fig. 3 is a plan vievv of one of the trucks of the Vehicle.

Figs. 4, 5 and (i are details illustrating structural features of the fixed trackA frame and of the truck.`

Like letters of reference in the severa-l figures indicate the sameparts.

In carrying the invention into practice, the fixed structure constituting theway over Whichthe vehiclesare propelled, embodies uprights or columns A, A, which will be of varying length orheight, dependingupon the contour of the surface, but with their upper ends at substantially thesame levely or at a levelvv'liich Will determine thegrade of the tracks forthe vehicles. These uprights or Supporting pillars-` are Aspaced apart adistance which will permit of connecting framing of a simple character but of suiiicient strength to` support the loads to be carried thereby, and they are preferably formed, as Ashown in detail in Figs. 4 and 5, of vertical channel irons A', Withinn'er and outer plates A?, rivetedthereto, such forms of metalbeing adopted as. will permit the use of stock niaterial' which may be conveniently and cheaply obtained.- it theirupper endsV the columns or supporting uprights are conh nected by llirons B, usually fastened in place by the customary angle brackets o, as in Well understood structural iron Work. The T-irons B are preferably located centrally over the columns and extend longitudinally throughout the entire length of the structure,therel being provided suitable di agona'l braces indicated at C to form a trusslike structure intermediate the column, so as to distribute the load more uniformly, and to relieve the connection between the columns and l`irons of shearing strains or any tendency of the structure to collapse by longitudinal Vniovein ent.

The 't`iro1is B form the base supports for the rails on vvhich the vehicles travel and lthey are preferably provided with overlyingA basev plates D riveted or bolted to the head flanges ofthe T-irons, as by bolts CZ and the base plates D extend laterally a short distance beyond the inner and outer edges of the columns A, as shown clearly in Figs. 2 and 5.

While theV rails E may be of the usual type and bolted or fastened directly to the base plates D, they are preferably held in place by means forming part of the framing and rail base, which' means also constitutes a guard to prevent disaster' should arvail break or a joint become disconnected at any point in the length of the track. ln the pre ferred construction and as shown, the base plate D is overlaid by a continuous track plate F having on the upper side a continuousoverhanging flange f beneath which one of the base flanges of the rail will seat throughout the length of therail, When the rail is` in position directly over the T-iron B. The opposite base flange of the rail is confined' beneath a removable fiangeplate f `may be a body for and the plates f and F are adapted to be clamped and locked firmly in position on the rail base B by bolts orrequivalent fastenings Gr,- passing through the several plates at a point somewhat removed from the edges of the plates, so as to be out of theway of parts of the moving vehicle and so as to leaveA the inner edges of the plates unobstructed, whereby, in an emergency they may form a guide to prevent lateral displacement of the vehicle.

The lvehicles arel adapted to be suspended below trucks H having flanged wheels h of the usual railway car construction and traveling on the tracks E, the arrangement being such that the body of the vehicle, which the conveyance of passengers as indicated at H or a body for the conveyance of freight, as will be readily understood, is suspended below the trucks by hangers 1 extending down on each side of the car body H and preferably substantially bounding the lateral dimensions of the car body, whereby any extreme lateral displacement would result in the hangers themselves being brought into contact With the edges of the track base plates or with safety guides to be hereinafter described.

The arrangement of the trucks running on the tracks directly over the vertical centers or axes of the columns imposes only compression loads on the columns themselves and, therefore, the latter may be of comparatively small cross sectional area, and the structure may be correspondingly cheapened in cost. With such a construction it is important that the columns on opposite sides of the car be connected together Wit'n sufficient rigidity and strength to prevent any possibility of the rails either spreading or the structure collapsing i1:- Wardly, and to meet this condition, the columns are arranged in pairs and connected together below the bottom of the car body, by transverse beams or girders K and above the plane of the top of the truck by transverse connections K', the ends of the latter being connected with upward extensions A3 preferably formed as integral parts of the outer plates A2 of the columns, as shown clearly in Figs. 2 and 4.

A structure of the kind described provides a convenientmeans whereby vehicles traveling on the tracks may be protected effectually against inclement weather conditions, such as would interfere with the running of the trains and against disastrous accident, through breakage of the truck hangers or the possible derailment of the trucks. To provide against the latter contingencies, safety slide rails are provided extending longitudinally of the track and connecting thel columns and transverse girders, as the case may be, which safety slide rails will, in an extreme emergency, receive and support the car body while permitting it to progress forwardly until arrested by the frictional resistance between themoving and fixed parts, without producing disastrous results. Conveniently, angle irons M are located in position below and laterally of the lower edges of the car body and are rigidly connected with the transverse girders l and columns A, while between the angle irons M and the rail base plates at the tops of the column supplemental safety slide rails M are bridged between the columns; thus the safety slide rails M', edges of the rail base plates and angle irons M, together, form continuous safety guides which will coperate with and support the car body even though the truck frames or trucks be broken or derailed. Under ordinary running conditions suilicient clearance is allowed between the car body or the hangers 1 and the safety slide rails to prevent any contact, and this clearance is approximately sufficient to permit the lateral displacement of the ianged Wheels to a point where the ianges of the wheels will be about central only of the rails E and hence, before the wheels can become entirely derailed, the safety slide rails will come into action to prevent further movement in that direction.

The structure is such that a comparatively light and cheap form of housing may be placed over and, if desired, down on each side of the truck space above the rails E. As a convenient construction, an arched roof, in the form of plates O may be sprung between the longitudinal L-irons P connecting the upper ends of the extensions A3, and the ends of the transverse connections K', and side plates O may be located on thc outer sides of the extensions A3. Either one or all of these plates may be hinged or removably mounted in position so as to facilitate repair of the fixed structure, 0r renewal in the case of deterioration. Because of the complete support afforded by the fixed framing, the inclosing plates may be of relatively light gage and still be amply strong to withstand any strain imposed upon them by wind pressure or the pressure of any snow or ice loads which may be accumulated.

The arrangement of the supporting track, trucks and car body is such that the center of gravity may be located at approximately the plane of the supportinnl rails, and consequently, even at high speer, there will be little or no tendency of the car to tiltin one direction or the other in rounding curves and hence banking at the curves may be reduced to a minimum, but in order to permit of a degree of iexibility Lacasse whichwill permit of the truclts conforming to the curvature of the rails, without imposing undue strains on the car body or hangers, the hangers I preferably terminate at their upper ends in slide blocks I2V located above the side frames of the trucks, while they hangers themselves extend through segmental slots 2 in the truck frames, with which arrangement the truck frames may assume a more or less angular position with relation to the car body and hanger, but at the same time relative lateral movement is eifectually prevented.

It will be understood that the supporting wheels of the truck and car body will be driven by any suitable power mechanism, where the car is a motor car; or where the car or a train of cars is adapted to be drawn by a locomotive or motor car, the wheels of the latter only will be driven by motor mechanism.

Inasmuch as the structure provides a means of transportation which is practically safe against disastrous accidents through breakage or derailment, it becomes possible to drive the cars at an exceedingly high rate of speed, and it is preferred that the surface which may cause reduction in speed due to air pressure shall be rounded or pointed in the direction in which the car is traveling, as has heretofore been proposed in motor driven vehicles adapted to travel at high speeds and which feature is therefore not illustrated in the accompanying drawings.
