SPECIFICATION forming part of Letters Patent No. 51 1,685, dated December 26, 1893.
Application filed April 19,1898. Serial No. 470,981. (No model.) Patented in FranceApril 11, 1893, No. 229,312; in Belgium April 13, 1893, No. 104,349; inGermany April 16, 1893, N0.'7l.523; in Canada May 31, 1893, N0.43,09'7,' in Spain June 26,
1893, No. 14,532, and in Italy June 30.1893,LXVI,328.
To all whom it may concern.-
Be it known that I, JOHN J AMES DAVIDGE CLEMINSON, a subject of the Queen of Great Britain and Ireland, residing at Dashwood House, Old Broad Street, in the city of London, England, have invented Improvements in Railway and Tramway Locomotives and other Vehicles, (which have been patented in the following countries: FranceApril 11,1893,
No. 229,312; Belgium April 13, 1893, No.-
104,349; Germany April 16, 1893, No. 71,523; Spain June 26, 1893, No. 14,532; Canada May 31, 1893, No. 43,097, and Italy June 30, 1893, No. 328, Vol. LXVL) of which the following is a specification.
In the specification of another'application for Letters Patent filed by me, Serial No. 470,848, I have described improvements in the construction of wheel bases for railway and tramway locomotives and other vehicles whereby such wheel bases can adapt themselves more effectually to curves in a railway or tramway than has been the case with constructions heretofore employed. According thereto the wheel base is constructed inter alia with one or more trucks each pivotally connected to the main frame of the vehicle at two points about either of which the truck is capable of turning when travelingover curves, under control of suitable controlling devices consisting in the examples illustrated in the drawings accompanying my said other specification of antifriction wheels or rollers carried directly by one of the pivoted parts and acting directly against guides fixed to the other pivoted part, the guide surfaces having pin 2.
Referring to Figs. 1 and 2 of these drawings, 1 is an end frame carrying pivot pins 2 2 arranged one at each side of the longitudinal center line of the truck, each of these pins being arranged to work, in the example shown, in a recessed holder or bearing 3 that is fixed to the main frame 5. 6, 6 are ant-ifriction wheels or rollers, or it may be slides, pivoted to'the ends of a lever 7 mounted to turn about the axis of a vertical pin 7 carried by the truck 1. 8 is a guide fixed in any suitable manner to the main frame 5 and formed with doublycurved surfaces 8 8 against which the rollers 6 6 work and one of which (8) is struck from the axis of the pin 2, and the other (8) from the axis of the The arrangement is such that the truck 1 is free to turn about the axis of either of the pins 2, 2 as a center when passing around a curve so thatthe axle of the pair of wheels 10 journaled in said truck can set itself automatically at right angles to the curved or straight portions of the track at all parts thereof, the guide 8 serving to control this movement and to return the truck to its normal central position whenit again enters a straight portion of the track.
In the modified arrangement shown in Fig. 3, the pins 2, 2 are each fitted in a block 3 fitted to slide in a slotted curved guide 4 that is fixed to the main frame 5 and the curved guiding surfaces of each of which are struck from the axis of the oppositely arranged pin 2 or 2. Also the guide 8 is formed with two pairs of curved surfaces 8 8, there being one pair for each antifriction wheel or roller (3.
In the modified arrangement shown in Fig. 4 there are two separate controlling guides 8, 8 one for each of the antifriction wheels or rollers 6, 6 each guide being formed with two curved guiding surfaces 8 8 arranged as before. This figure illustrates the application of the truck as a leading truck, to an eight-wheel vehicle, such as a locomotive. Fig. 5 shows a wheel base with two such trucks, one at each end of the main frame'5, these trucks being connected by bars 11 the outer ends of which are fixed to the respective trucks and the inner ends of which are conor rollers instead of being carried by a lever pivoted to the truck and working against a guide or guides 8 fixed to the main frame, may be carried by a lever pivoted to the main frame and arranged to work against a guide or guides fixed to the truck.
Trucks pivoted and controlled in the manner hereinhefore described can be used in vehicles constructed withan intermediate truck capable of turning about a vertical axis and also of moving in a lateral direction relatively to the body of the vehicle as described in the specification of my said other application for Letters Patent.
hat I claim is- 1. A railway ortramway vehicle having a truck pivotally connected thereto at two points, and means for controlling the turning movement of said truck about each of said points, said means comprisingalever mounted on one of the pivoted parts, and a guide having guiding surfaces in the form of arcs of circles and againstwhich antifriction devices carried by said lever work substantially other of said pivoted parts, and antifriction devices carried by the ends of said levers and arranged to work against said guiding surfaces substantially as herein described.
3. In a railway or tramway vehicle, a wheel base comprising a main frame, a truck provided with pivot pins 2, 2 arranged one at each side of the longitudinal center line of the' truck, slotted or recessed bearings 3 for said pins fixed to. said main frame, a lever pivoted to said truck and carrying antifriction wheels or rollers at its ends, and guides with curved guiding surfaces 8 S carried by said main frame and against which said antifriction wheels or rollers act substantially as herein described for the purpose specified.
In testimony whereof I have signed my name to this specification. in the presence of two subscribing witnesses.
