PETER HERBERT, OF NORTH SYDNEY, NEV SOUTH W ALES, AUSTRALIA.
UNDERCARRIAGE FOR TRAIVI OR RAILWAY CARS OR WAGONS- SPECIFICATION forming part of 'Letters Patent No. 766,348, dated August 2, 1904.
Application filed October 7, 1903.
To all whom, it may concern.-
Be it known that 1, PETER HERBERT, a sub- 1 ject of the King of Great Britain and Ireland, 1
and a resident of Chester, Karrabar Road,
North Sydney, county of Cumberland, in the 1 State of New South \Vales, Commonwealth of 1 Australia, have invented a certain new and useturn-table upon which the under-frame provided with antifriction-rollers will rest. To this skeleton turn-table there will be no center-pin or king-bolt. The turn-table will be maintained in position relative to its theoretical center by a number of peripheral antit'riction-rollers on vertical axes on the underframe and which rollers will engage with the periphery of the turn-table. Each turn-table will carry but one axletree supporting one pair of wheels. Upon the turntable may be mounted a suitable motor-engine for driving the wheels. \Vhen the wheel-base of the car is very long, a set of pony-wheels are provided to each turn-table. The pony-wheels are mounted in a pony-frame adapted to slide transversely below the underframe, such ponyframe being connected to the main turn-table by diagonal rods and a pivoted. compensating lever. The turn-table and the pony-frame will together thus constitute a kind of bogieframe.
In order that the invention may be properly understood, reference is made to the accompanying sheet of drawings, in which Figure 1 is a plan of the underframe, the turn-table and the bogie-frame running on a straight track. Fig. 2 is a similar plan, but with the car running on a curve of forty-six feet radius. Fig. 3 is a side elevation of Fig. 1. Fig. 4: is a longitudinal vertical section on the center line of Fig. 1. Figs. 5, 5, 5"
are side elevation, end elevation, and plan, respectively, of the compensating lever, showing its attachment to the chord-piece of the Figs, 6, 6, 6 are cross-section,
turn-table.
Serial No. 176,127. N!) modelf end elevation, and plan, respectively, of one of the antifriction-bearing rollers, showing its attachment to the underframe and its relation to the turn-table. Figs. 7, 7, 7" are cross-section, end elevation, and plan, respectively, of the supporting antifriction-roller, showing its attachment to the underframe and its relation to the turn-table. Figs. 8, 8, 8 are cross-section, side elevation, and plan, respectively, of one of the peripheral antifriction-rollers.
A is the external portion of the underframe of the ear and is constructed of angleiron.
B B B B B" are cross-beams in the underframe constructed of channel-iron, but of less depth than the angle-iron A, which constitutes the external portion of the underframe.
C is the turn-table, which carries the axletree I) and wheels E E. The turn-table C is maintained in its central position by the peripheral antifriction-rollers F F. (Shownon an enlarged scale at Figs. 8, 8*, 8".) Antifriction-bearing rollers (Jr (vr (shown at Figs. 6, 6, 6") on horizontal axes in the underframe re duce the friction between the under side of the under-frame A and the upper side of the turn-table 0. Another antifriction-roller, H, (shown at Figs. 7 T, 7",) is placed under the turn-table in order to assist in supporting the weight of any motor-engine the turn-table may have to carry.
\Vhen the wheel-base of the car is long-say twenty feet and up wardpony-wheels must be provided to assist in carrying the underframe; but as the improved undercarriage is specially adapted to travel round curves of small radius special appliances must be provided to prevent tangential friction between the flanges of the wheels and the rails. To this end the pony-wheels L are carried by a pony-frame J, in which is a slotK, traversed by a centerpin K, carried by the cross-piece B in the underframe. The pony-frame J is adapted to slide transversely with respect to the underframe. Long antifrietion-rollers M M, carried by the underframe, rest upon the upper surface of the pony-frame J, and thus assist in supporting the body of the car, while at the same time the pony-frame can move or swing under the car without undue friction. 1n the turn-table C is a chord-piece N, to the center of which is pivoted at O a compensating lever P. (Shown in detail at Figs. 5. 5, 5.) The pony-frame J is connected to points Q, Q, on the compensating lever P by bars or connecting-rods R R, and the com-- pensating lever is prevented from turning too far in eitherdirection by stops S S on the chord-piece N.
Fig. 2 shows the car traveling round a curve having a radius of forty-six feet with a wheel-base of twenty feet between the driving-wheels and clearly indicates the positions that the driving-wheels and pony-wheels will assume relatively to the underframe when traveling round such a curve.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In undercarriages of tram-cars, in combination the underfraine of a tram-car, a skeleton. turn-table upon which the underframe rests, antifriction-bearing rollers between the turn-table and the underframe, peripheral rollers around the turn-table, an antifriction supporting-roller below the turntable, and axletree and wheels carried by the turn-table and supporting it, as specified.
