ELEVATED CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent No. 395,073, dated December 25, 1888.

Application filed April 18,1888. v Serial No. 271,096. (No model.)

To all whom it may concern.-

Be it known that I, HOWE PAIGE, a citizen of the United States, and a resident of the city of Minneapolis, county of Ilennepin, State of Minnesota, have invented certain new and useful Improvements in Elevated (fable Railways, of which the following is a specification, reference being had to the accompanying drawings.

Elevated railways as generally constructed take up much space in the public streets, and

- are a great nuisance to the adjacent property.

The general object of my invention is to re duce these objectionable features as far as possible. To this end I provide a car and a track of peculiarconstruction. I use asingle rail mounted on a continuous iron girder supported on a single row of upright columns. The girder is made to serve as a conduit for the cable, and the car is supported from the single rail with its center of gravity below the point of support.

In the drawings, like letters referring to like parts throughout, Figure l. is a vertical cross-section. Fig. 2 is a side elevation of the track and the car-supporting truck, the car itself being removed; and Fig. 3 is a general view, in side elevation, illustrating the system. Fig. lis a detail.

A are the metallic supporting-eoluinns. B is an I-shaped steel girder supported on and securely bolted to the tops of the upright -ing so placed as to break joints with the girders. I

D D are horizontal guide-bars attached to the posts below the girder and extending the whole length of the track;

E E is the truck, taken as a whole.

F is the car, and G is the cable. The cable is supported on idler-sheaves II', which are loosely mounted on short shafts 71, secured to the girder between its upper and lower flanges. The truck E is in shape somewhat like asaddle, the horizontal yoke 6 corresponding to the seat and the pendent parts e e corresponding to the stirrups.

Directly under the yoke and between the pendent parts are the supporting-wheels E,

journaled in suitable boxes secured to the opf" f, suitable for passengers or freight.

posite sides of the yoke. The pendent parts straddle the track, and are preferably provided with right-:mgled projections or arms 6 at their lower extremities, which serve as seats for springs. The pendent parts 2 e are farther apart at their lower than at their upper ends, being bent upon themselves outward and then downward at points directly opposite the girder when in position on the t rack.

To the pendent parts e and e are attached horizontal rollers II in proper position to bear against the guide-bars D whenever the truck swings the least bit to either side. As there is one set of rollers on each side of the guidebar, only a very limited oscillation is allowed to the truck. cut away, conforming in shape to the truckframe E, and is mounted on the truck as a rider sits in a saddle. The car is thus divided by the part of its frame l which fits over the truck into right and leftcompartments, The top piece or yoke-bar, f, of the center frame, F, is provided with a seat, Ii, and the truckframe E is provided between two wheels with a foot-board, l, affording a place for the operator of the car. The col'npartment-s f f may be provided with seat-s M for passengers.

Springs N and N are interposed between the yoke f and the truck-frame, both at the top and on the sides. The springs at the side should be attached either to the car alone or to the truck alone, so as to allow freedom of oscillation.

On the arms e may also be placed springs N directly under the floor of the compartments f and f. These springs, if used, are made fast to the arm 6', and are not connected to the car. As shown, the floors of the compartments are provided with grooves or guides P, in which is a movable cross-head, 1", which is bolted to the top of the spring. By this construction the car is allowed to oscillate on the springs, the groove and cross head allowing the necessary lateral motion to the car without disturbing the spring. The groove and cross-head may, however, be dispensed with and the car be allowed to rest freely on the spring and move over the same. The cross-head and guide are preferred, as they The car F has its central part allow the lateral motion without danger of displacing the spring by movement lengthwise oi the car.

Q is a grip, of any suitable construction, which is mounted on the truck-frame adjacent to the operators seat, and is provided at its lower end with jaws q for gras 'iing the cable. The cable is driven from a source of power at a ctmtral station in the customary manner.

to its elevated and exposed positiointhe cable 2 can be readily reached for repairs, and is never obstructed by snow, ice, or dirt. center of gravity oi the car is below the point of support, and hence derailmei'it is practically impossible.

The

said guides, and the springs N, rigidly scoured to said arms and to said cross-heads, substantially as described.

3. In an elevated railway, the cmnbination, with a single rail and a single row of supporting-columns, of an I-shaped girder adapted to tie together the columns, support the rail, and serve as a cable-conduit, idler-sheaves secured to said girder between its upper and lower flanges, and an endless cable supported on said sheaves, substantially as described.

l. The coml'iination, with a single-rail elevated track having an I-shaped girder for supporting the rails, of a car-propelling cable mounted on said girder in the space between its upper and lower flanges, a car depending from said rail with its center of gravity below the point of support, and a grip for connecting the car to the cal )lc, substantially as described.

5. In a sin gl e-rail elevated railway, the combination, with an I-shaped girder adapted to tie together the'snpporting-colnmns, support the rail, and serve as a cable-coliduit, of a cable mounted on said girder between its upper and lower flanges, a saddlcshaped truck supported from the single rail with its pendout parts on the opposite sides of the track, a

The passengemompartmenls of the car may 1 be brought comparatively n ear the street-level without interfering with objects, thus atio'rding convenience of access without climbing long flights oi slab-ways. The car is free to rise and tall or swing latemlly without any tendency to displace the truck; and economy of power is effected by applying the cable substantially on a line with the cars center of gravity.

\Vhat I claim, and desire to secure by Let ters Patent oi' the lfnitcd States, is as follows: 1 l. The combination, with a single-rail elevated track, of a saddle-shaped truck supported from said track with its pendent portions on the opposite sides thereof, a saddlc- I shaped car mo uni ed on said truck, and sprin interpostul between the truck and the car, the springs between the yoke-pieces of the car and truck being fast'to both, and the springs between the pendent portions of the car and truck being fast to one part only, substantially as described, whereby the car is free to oscillate on the truck.

L. The combination, with the ear-trnek It, consisting oi. the parts E c 1/, having the lateral arms c, of the car I? l*" f f, having the guides l", the cross-heads l", movable in saddle-shaped car mounted on said truck, the center of gravity of the truck and car taken together bein below the point of support, and a grip mounted on said car and truck for de tachably connecting the same to the cable, substantially as described.

(5. The con'ibination, with a single series of fixed upright posts, of I shaped girders secured to the tops oisaid posts, I-sl1aped rails secured to the tops of said girders, a saddlei sl'iaped truck supported from said rail with its depending parts on the opposite sides of the track, a saddlesl1aped car mounted on said truck with its dependent parts on the sa m e hori Zl mtal level with the dependent parts of the truck, a cable moui'ited on said girder between its upper and lower flanges, a grip on the car and truck. for connecting to said cable, a horizontal guide-bar secured to said posts, and horizontal anti-friction rollers secured to the dependent portions of said truck adapted to bear against said guide-bar and limit the lateral motion of the truck, suliistantially as described.
