Definitions
- This invention relates to a flask made for the purpose of casting throttle-valves.
- Said flask is composed of a cylinder bored out to the diameter' of the seat into which the valve has to t, and provided with suitable blocks, the inner ends of which, when properly putJ together, form the mold for the valve to be cast.
- Said blocks are held in position by a screwclasp, so that they can be screwedup as the metal shrinks, and a suitable hole passing transversely through the cylinder allows of introducing the pin or rod which forms the core for the axle ofthe Valve in such a manner that the hole for the axle is cast in and a valve is obtained, which is ready to be put in its seat immediately upon being removed from the mold.
- A represents a cylinder, made of iron or any other ⁇ suitable material, and bored out-to correspond to the seat or tube into which the valve is to be tted.
- This cylinder is provided ⁇ with two blocks, B O, the inner ends of which are so shaped that the same, when properly put together, form the mold for the valve to be cast, as clearly shown in Fig. 1 ofthe drawl ings.
- A1 hole, a which passes transversely through the cylinder A, allows of introducing the core b for the purpose of producing the hole for the axle of the Valve.
- the blocks B O are held in position by a screw-clamp, D, as clearly shown in Fig. 1, and the screws c d serve to screw'up the blocks as the metal shrinks.
- Suitable channels e serve to admit the molten metal, and otherl channels, f, allow the air from the mold to escape.

This invention relates to a flask made for the purpose of casting throttle-valves. Said flask is composed of a cylinder bored out to the diameter' of the seat into which the valve has to t, and provided with suitable blocks, the inner ends of which, when properly putJ together, form the mold for the valve to be cast. Said blocks are held in position by a screwclasp, so that they can be screwedup as the metal shrinks, and a suitable hole passing transversely through the cylinder allows of introducing the pin or rod which forms the core for the axle ofthe Valve in such a manner that the hole for the axle is cast in and a valve is obtained, which is ready to be put in its seat immediately upon being removed from the mold. f
A represents a cylinder, made of iron or any other `suitable material, and bored out-to correspond to the seat or tube into which the valve is to be tted. This cylinder is provided` with two blocks, B O, the inner ends of which are so shaped that the same, when properly put together, form the mold for the valve to be cast, as clearly shown in Fig. 1 ofthe drawl ings. A1 hole, a, which passes transversely through the cylinder A, allows of introducing the core b for the purpose of producing the hole for the axle of the Valve.
The blocks B O are held in position by a screw-clamp, D, as clearly shown in Fig. 1, and the screws c d serve to screw'up the blocks as the metal shrinks. Suitable channels e serve to admit the molten metal, and otherl channels, f, allow the air from the mold to escape.
By these means a throttle-Valve can be cast which requires no itting and which lis ready to be put in its seat immediately as it comes
