To ALL WHOM IT MAY eoNeEnN; Y
Be it known that I, CORNELIUS KINGSLAND, of MeKeesport,.in the county of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Car-Wheels; and I doy hereby declare that'the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the f letters of reference marked thereon.
In casting car-wheels in chills for the purpose of hardening the tread ofthe wheel, -the periphery of the `.vhecl is the iirst that cools, and this chilled portion is changed so that the particles of iron are more dense and brittle, and the whole wheel cools on a strain, and is very liable to crack or split. i To overcome this didiculty in casting, the wheels after they are cast are placed in deep pits, and covered up, so that they may gradu ally c0ol,'but notwithstanding this trouble and care, the wheels often crack, and always cool cn a strain..
.The nature of my invention consists in the method of' constructing car-wheels, as hereinafter described.
- To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. In the accompanying drawings, which form part of my specification- Figure-1 `is a sido view ot' mymproved ear-wheel.
Figure 2 is an-edge view of the same.
Figure 3 is a top view of the chill" in which I castmy improved car-wheel.
Figure 4 represents a transverse section of the car-wheel and its chill.
I construct the chill and wheel in any of the known forms. But I cut away a portion of the chill A under the flange X of the wheel, so that in moulding and casting the outer part of the flange will resten sand, and thereby cause the flange of the wheel in casting to have a full and perfect edge. The chill is provided with a number of recesses, marked o. In these recesses are placed cores, which ferm/the recesses t' in the wheel B. I iill up the recesses z'in the wheel with suitable pieces of steel, which are provided with teeth similar to the teeth ot` a file. These pieces of steel are made hard and then driven-into the dove-tailed recesses.- The yrecesses may also be filled w'ith hard metal, melted and poured into the recesses until the metals become knit together. I wish it clearly understood that I do not confine myself to the two methods of filling up the recesses-t'. I also desire it to be understood that I do not confine myself to the number or form of the recesses z' in the wheel.
The advantage of my improved method of constructing carlwheels consists in relieving the wheel from all undue strain in cooling oli after being cast, and also from all undue strain caused hy change of temperature in the Weather, or by the action of the wheels upon the rails when the cars are in motion or at rest. Another advantage consists in being able to cast and cool ofi` the wheels without the use of cooling-pits. These advantages, with othcrs, such as strength, durability of the wheels, and the saving of stock in casting, are things that have long been desired by the manufacturer and those using car-wheels. I
Having thus described my improvement in ear-Wheels, what I claim as of my invention, is i l The method herein described for constructing car-wheels.
o. KINGSLAND.
