(Cl. 280—80) The method now ‘generally adopted fortrans stands in the channels of longitudinal members b porting railway cars by road consists in using a of the platform or bridge of the trailer, the mem tractor and.- a trailer, supporting the front part bers being of U-section. The rear axle of the and the rear part of the car respectively, and for 5 some reasons the best form of trailer is one hav ing a forwardly extending platform or bridge resting on a rotatable saddle or swivel seat on the car is over the wheels 0 of the trailer, and the front axle is over the rear wheels of, e of the trac tor s. The trailer wheels 0 are carried by stub Ul axles f pivoted to transverse members 111 of the tractor, as by this means additional load is placed bridge, and are connected to each other by springs on the tractor, causing the wheels thereof to g and balance levers It so that the load is evenly 10 obtain a suf?cient grip on the road, though the distributed on them. tractor itself may be comparatively light. A At each side of the rear part of the tractor defect of such tractor and trailer combinations, as . there are three wheels, namely two wheels d side heretofore constructed, is that the front wheels by side and a wheel e running in the track of the of the railway car cannot be brought su?iciently outer wheel :1. The wheels e are carried by stub :5 far forwards to place the load well over the rear axles and the groups of wheels d are cap-able of 15 wheels of the tractor. This is due to the fact that swinging in the direction of travel. The two the front part of the platform or bridge referred wheels d belonging to- each group are connected to has an upward bend, to enable it to rest on the to each other by a balance lever, and at its ful swivel seat, and this bend limits the forward run crum this lever is connected to a spring 2' con 20 of the car. Of course it would be possible to raise nected to the stub axle of the wheel’ e.

E Q ‘ spring i is ?xed to the spider at the center of Fig. 4 is a plan view showing a method of gravity of the wheel system. mounting two side wheels of a tractor. In the modi?cation shown in Figs. 5 and 6 the Figs. 5 and 6 are respectively a side view and two wheels (Z side by side are connected by a a plan view, illustrating another method of balance lever m, and a cantilever wheel i connects mounting the tractor wheels. this lever to the stub axle of the spring e, so that Fig. 7 is a sectional side view showing one there are several pivotal connections through form of coupling between the tractor and trailer, which the wheels take the load.

These Figs. 12 to 14 show another form of coupling, cups and bosses are so placed that the load is Fig. 12 being a side view and Figs. 13 and 14 evenly distributed on the wheels. being plan views to a larger scale. Figs. 7, 8 and 9 show a construction of the Referring ?rst to the composite conveyance swivel seat in which there is a step bearing 10 Cr shown in Figs. 1, 2 and 3, the railway car a, separate from the pivot bearing u. The bearing 2 2,085,353 p is arcuate, conforming to a segment of a circle having its center at the axis of the pivot u, and at the front end of the trailer bridge there are two projections q, which rest on the bearing p, and can slide thereon. Fig. 9 shows a coupling on the trailer, for automatically engaging the pivot. As shown in Fig. 7 the trailer has a retractable wheel 01 near the front end of its bridge, for‘ supporting the same till the coupling is engaged. The wheel is 10 carried by a lever 02, which can be rocked by means of a screw spindle c‘3 and swivel nut c4 for lifting the wheel. 15 backed on to! the trailer. The pivot u enters the gap between the two projections q and forces apart two pivoted jaws o thrust towards each other by springs 121, which cause the jaws to grip the pivot when the pivot lies between two arcuate portions thereof. The jaws are then which project from its ends. When the part q3 is pushed between the ?anges y these pins are thrust inwards till they‘ face recesses e2 in the ?anges, into which they engage. Studs on the pins are engaged with slots in bell crank levers .23, which can be rocked by means of a cord for 1O disengaging the pins from the recesses 22.

In a composite road vehicle the combina 15 tion of a trailer‘ having road wheels and a plat form between said wheels below the level of the tops thereof, and a tractor having trailing wheels and a swivel seat supported below the tops of said Wheels and adapted to connect the trailer to the tractor whereby the front end of said 20 platform is supported between said trailing locked by means of a shackle v2. The opening of the jaws is effected by a spin— dle a: which is rotated by a hand wheel m1 and has a right and left hand thread engaging with nuts y slidable in the forked ends of arms 3 revoluble on the pivot‘ pins 32 of the jaws 22. Turning the spindle in one direction causes the arms 2 to swing inwards so that they engage ex tensions y3 on the jaw members and thereby ‘ Figs. 10 and 11 show a modi?cation in. which a coupling device similar to that shown in Fig. 9 is provided on the tractor, behind the step bear ing, the pivot 11.1 being‘ in this case of course on the trailer. a bore containing a spring a and two pins .21 1s:- - For engaging the coupling the tractor is open the latter. tween which the part (13 lies. For locking the part q3 upon the member a: the ridge wl has The part q of the trailer, resting on the step bearing, need not in. this case have a gap for passage of the pivot. The pivot u1 on the trailer is on the underside of the trailer plat form, and is consequently not in view when the coupling is being made, for which reason the construction shown in Figs. '7, 8 and 9 is gen erally to be preferred. Figs. 12, 13 and 14 show a modi?oation‘in wheels below the tops thereof. ‘ 2.
