RAILROAD-TRUCK.

SPECIFICATION forming part of Letters Patent No. 715,791, dated December 16, 1902.

Application iile. July 14, 1902. Serial No. l1 5,579. (No model.)

To @ZZ whom, t wea/y concern.-

Be it known that I, WILLIAM C. HAPPE, a citizen of the United States, residing at Davenport, in the county of Scott, State of Iowa, have invented certain new and useful Improvements in Railroad Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railways; and it has for its object to provide arailway in which the rails will be elevated and upon which the cars will be held securely against displacement when traveling at enormous speed.

A further object of the invention is to provide a construction which will permit of use of lighter cars than is customary.

An additional object of the invention is to provide an arrangement for holding the cars upon the track which is adjustable and may be adjusted at both sides of the cars from a single point upon the car, other objects and advantages of the invention being understood from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views,Figure 1 is a transverse section through a trackway embodying the present invention and a car thereon, portions being shown in elevation. Fig. 2 is a side elevation of a portion ofa trailer-car and illustrating the arrangement of the wheels at one side of the truck. Fig. 3 is a View similar to Fig. 2 and showing a double truck such as is used upon the motor-car. Fig. 4 is an end elevation of a truck. Fig. 5 is a section on line 5 5 of Fig. 2 and showing the sliding arrangement of the upper wheelat one side of the truck. Fig. 6 is an elevation of the screw at one end of the truck which adjusts the upper wheel. Fig. 7 is a plan View of the mechanism for adjusting all of the screws of the truck simultaneously. Fig. 8 is an elevation of one of the tension-screws. Fig. 9 is an end elevation of a motor-car and illustrating the truck and the arrangement of the parts for varying the tensions of the springs that hold the upper wheels against the angular rails.

Referring now to'the drawings, the present trackway comprises a plurality of pairs of upwardly-con verging posts 10 and 11, which are preferably of skeleton formation, as shown, the lower ends of which are secured to and rest upon the foundations or bases 12 and 13 and are connected at their lower ends by the strut 14, there being also ties 15 and 16, which ext-end diagonally from the lower ends of the posts to the upper portions of the opposite posts. Secured to the posts of each pair is a cross-beam 17, on which are mounted a pair of beams 18 and 19, which support rails 20 and 21, the beams 18 and 19 being connected by a suitable number of ties 22. Upon the upper ends of the posts and extending longitudinally of the trackway are the angleirons 23, upon which are secured the channelirons 24, one flange 25, which is the inner flange of each channel-iron, receiving between it and the flange 26 of the corresponding angle-iron one flange of an angle-iron 27, the several flanges being riveted together, as shown. The angle-irons 23 are in fact upper rails and are engaged on their under faces by the upper wheels of the car-trucks hereinafter described. The trucks of the cars that travel upon this trackway have lower supporting-wheels 30, that run upon the rails and 2l, and have also upper wheels 50, that run against the under faces of the upper rails and prevent the wheels 30 from leaving the lower rails. The passenger-cars have their trucks provided with one upper wheel at each side, as shown in Fig. 2, while the motor-car has two upper wheels at each side of the truck, as shown in Fig. 3.

In Fig. 2 ofthe drawings there is shown the truck for passen ger-cars, while in Fig. 3 there is shown a truck for a motor-car, Figs. 4 and 6 having also reference to the motor-car, as well as Figs. 7 and 8. The bolster 30 of the truck is disposed upon the longitudinal beams 31', having boxes 32, in which turn the ends of the axle 33, that carries the wheels 30, that run on the rails 2O and 21. Upon the upper face of the bolster 30 is mounted the U- shaped frame 35, the ends 36 and`37 of which are passed upwardly at the sides of the body of the car 38 and are slidably engaged with die-plates 39, which latter are secured to the sides of the car-body. The truck is thus held against movement longitudinally of the carbody and the car-body is permitted to have IOO vertical movement with respect to the truckbolster, the body being sustained by the helical springs 40, which rest with their lower ends upon the frame 35, while upon their upper ends rest the longitudinal sills 4l of the car-body.

Upon the sides of the car-body at opposite sides of each of the plates 39 are secured dieplates 42 and 43, in which are slidably mounted plates 44 and 45, having other plates 46 and 47 slidably mounted therein for vertical movement, and these last-named plates have openings therethrough, through which are passed the axles 49 of wheels 50. The axles 49 are mounted in bearings 51 on body-bolsters 52. Passed through the body-holsters 52 and through the corners of the truckframes 53 are bolts 54, the lower portions of which directly above the truck-frame are threaded, and with the threaded portions are engaged nuts 55, having gear-teeth on their outer faces, so that they are in effect pinions. On the bolts 54 and resting with their ends, respectively, against the bolsters 52 and the pinions 55 are helical springs 56, which sustain the bolsters 52 and therewith the aXle 49 and its wheels 50.

Mounted upon the truck are the shafts 57 and 5S, each having a pair of worms 59, and each of these worms engages a pinion 55. The

shafts

57 and 58 carry bevel-

gears

60 and 61, which mesh with

similar gears

62 and 63 on a transverse shaft 64, having also a pinion 65. A vertical shaft 66 is mounted on the front platform of the car, and xed to its upper end is a hand-wheel 67, which is located convenient to the motorman. The shaft 66 carries a worm 68, which meshes with the pinion 65, and thus when the handwhcel is rotated the

shafts

57 and 58 will be actuated to turn the pinions 55 in corresponding direction, so that they will be fed upwardly or downwardly of the bolts. As the pinions feed upwardly the tensions of the springs 56 are increased and the wheels 50 are pressed upwardly with increased force. The wheels 50 are arranged to run against the lower sides of the angular upper trackrails and prevent the truck from rising a distance sufficient to cause the wheels to leave the track-rails 2O and 2l.

In Figs. 2 and 5 is shown the arrangement of truck for passenger-cars, wherein there is only one upper wheel at each side of the truck. The passenger-car is also shown in Fig. l of the drawings. Referring now to Fig. 2, the car-body 70 has a die-plate 7l fixed thereto, in which is slidably engaged an arm 72 of a U-shaped plate similar to the plate or fram'e 35, it being understood that there is a die-plate 7l at each side of the passenger-car, the U-shaped plate or frame being mounted directly upon the truck-bolster 73 and there being helical spring 40 between the web of the U-shaped frame and the sills on the bottom of the car-body to sustain the car-body yieldably. 'In the end portions 72 of the U-shaped frame are slidably mounted plates 74, having stub-shafts 75, which carry wheels 76, which run against the under side of the angular upper rails of the traokway. Helical springs 77 are disposed upon the bolster 73 and sustain the plates 74 yieldably. With this construction it will be seen that the upper wheels prevent the lower wheels from rising from the track on which they run, the play of the plates 74 vertically being less than the depths of the flanges of the lower wheels, so that the lower wheels cannot rise sufficiently far to permit their fianges to pass over the rails.
