WILLIAM H. MASo'N, oF BOSTON, MASSACHUSETTS. Letters Patent No. 87,1 80, dated February 23, 1869.
IMPROVED RAILWAY-CAR WHEEL.
The Schedule referred to in these Letters Patent and making part of the lame.
To all'whom it may concern Be it known thatI, WILLIAM H. MASON, of Boston,- in the county of Snfl'olk, and Commonwealth of Massachnsetts, have invented a new and useful Improvement in Gar-Wheels; and I do hereby declare that the following is a full and exact description thereof, reference being bad tothe accompanying drawings, and the letters of reference marked thereon.
To enable others skilled in the art to make and use m invention, I will proceed to describe its construction.
The object of my invention is to provide a doublespoked car-wheel, which has the spokes directly connected with the hub and felloe, andwhich is so contrived that it can be cast in one piece, with a single greensand core, thereby making a very great and important saving in'expense of construction, while it has all the requisite strength, with less weight of metal than other ing, with a dry-sand core, and conuectthe opposite sides of the mould by a green-sand core, a method less expensive than the other, and which cannot, to my knowledge, he used in spoked wheels as now con- 7 structed.
In the accompanying drawings- ,7
Figure 1 represents a side view of the wheel or plan of the exterior surface on itsinner side.
Figure'2 is a transverse section at the line A B, from the circumference to the centre of the -wheel, showing the curves, or corrugations in the outer or inner surfaces of the spokes.
a a a are the curves above mentioned.
The object of the curves, or corrugations of the M spokes (toprevent cracking or warping when the iron is cooling) is too well-known, and the device is too com-' mon to need a description. Still, their use is necessary in my wheel, on account of the length of its spokes.
I do not claim all cast car-wheels having spokes, nor all cast car-wheels having curved spokes; but
I do claim'a cast car-wheel in one piece, having two sets of curved spokes, each set arranged upon the opposite sides of the wheel from the other set, and the spokes of one set directly opposite the spokes of the other, when the spokes extend from the hub to felloe, all substantially as shown, and to accomplish the purpose specified.
' WM. H. MASON.
