IMPROVEMENT IN SWITCHES FOR CHANGING GAUGE OF CARS.

The Schedule referred to in these Letters Patent and making part of the saine.

To all whom it 'may concern.:

Be it known that I, THOMAS Foce, of St. Marys, in the Province of Ontario and Dominion of Canada, have invented a new and improved Switch for Changing Gauge of Cars; and I do hereby declare thatthe following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and `use the same, reference being had to the accompanying drawing forming partei' this specification, in which- Figure 1 represents a plan or top View of my improved switch applied to a double-gauge track.

Figure 2 is a transverse vertical section of the same.

Similar letters of reference indicate corresponding parts.

Thisinvention has for its object to provide a switch by means ot' which cars having adjustable wheels can be shifted from narrow to broad-gauge tracks, or m'ce versa., by the power of a locomotive-engine.

At present the change of the4 wheels from narrow to broad, or from broad to narrow gauge is effected on double rails, which gradually diverge 0r converge to the desired width. On such ogee lails the cars can not be moved along by locomotive-engines, which have no adjustable wheels, and consequently the change has lto be produced by moving each car by muscular power over the changing rails. This operation is quite tedious and laborious. To facilitate it I have made the ogee rail on one side of the track only, and combined it with a switch which will accommodate' itself to the `gauge of the locomotive, so that either a narrow or broad-gauge engine can be used for spreading or contracting the wheels of an entire train of cars.

for transferring cars from the narrow to the broad t gauge, or nice versa.

The switch-rail D is connected with a weighted lever, E, by which it will be held either againstthe rail B 0r against the check-rail F, as in fig. l.

G is a check-rail for A.

H, a check-rail for 15, converging with the inner rail D.

The check-rail F of C is gradually bent outwardly to becomefthe check-rail also of B beyond-the switch.

It' the cars are to be moved from the narrow gauge to the broad the switch is set against the rail B. The engine can follow or precede the cars on the broad gauge, the switch giving way to it when it approaches; so also a broad-gauge engine can be used for changing the cars from a broad to a narrow gauge, the switch being set in front of the engine to keep'it on the rail B while the cars are transferred to G.

Having thus described my invention,

I claim as new and desire to secure vby Letters Patent- The combination of the broad and narrow-gauge rails B and O with the adjustable switch-rail D, for permitting the transfer of cars from narrow to broad gauge, and cioe versa, as specified.

THOMAS FOGG.
