IMPROVEMENT IN TABLE FOR CHANGING GAUGE OIE' RAILWAY-CAR TRUCKS.

The Schedule referred to in these Letters Patent andmakng part of the same.

To all whom 4it may concern:

Be it known that I, GEORGE F. MORSE, of Portland; in the county of Cumberland and State of Maine, have invented a new and useful Table-for Changing Gange of Changeable Gauge Car-Trucks; and 1 do hereby declare the following to be a full, clear, and exact description thereof', which will enable others to make and use myinvention, reference heilig had to the accompanying drawings forming part of this specication, in which- Figure l is a top plan oi' my invention, showing the table, rails, Ste.

Figure 2 is a vertical end section of the same, arranged for changing from narrow to broad.

Figure 3 shows a pair of wheels, in position for changing from broad to nau'ow gauge.

lhe purpose of my invention is to produce au arrangement of devices for the purpose of changing gauge of changeable gauge car-trucks; and

1t Vconsists in the application of inclined surfaces, whereby the weight ofthe car assists in changing the gauge ofthe trucks.

a a, in figs. 1 and 2, and a', in fig. 3, show the tracks upon which the car is run preparatory to the truck being changed.

These tracks bear upon inclined surfaces, shown by b b, in figs. 1 and 2, and b', in fig. 3.

These inclined planes b b b are confined to each pltler, and kept at proper distances apat by the bars lhe tmcks a are kept 1n tuen' proper places by the screws c c', igs..1, 2, and' 3.

The screws are confined by the stops f f, (figs. 1 and 2,) and in iig. 3 the screws are represented as iight and left-hand, connected by a'single nut, e.

The operation of changing gauge, say from narrow to broad, (see figs. l. and 2,) is as follows:

Thetruck to be changed is run upon the tracks a a, which are then at the highestpart ot' the incline. The wheels and axles are then prepared for the change, the wheels being loosened, so as to move freely on the axles. The tracks c a are then drawn ont by means of' the screws c, bringing with -them the wheels, the weight of the car materially assisting in the operation, having a tendency to press the tracks outward on the inclined surfaces, as well as downward. The stops ff arrest the tracks c a when they havereached the broad gauge. .Lhe truck is then run off' upon the broad-gauge rails.

The operation of changing gauge from broad to narrow is the same in principle as that above described, excepting that the inelines are reversed in posit-ion, the tracks moving inward and downward, as shown in tig. 3. In this figure the screw c' is represented as extending across the table, between the rails a' a', and

operating in a right and left-hand nut, c.

`What I claim as my invention, and desire to secure by Letters Patent, is-

1. The inclined planes of the tables b b' and tracks a a', as herein shown, operating asdescribed.

2. In combination with the said inclined planes, the stops f and f'. 3. In combination with Ythe said inclined planes, the screws c and right and left-hand screwc.
