Description
@einen tat-ra @anni @ffice W. R. 4T HoMAs, 0F GATASAUQUA,V PENNSYLVANIA. Letters Patent No. 70,290, dated October 29, 1867.
IMPROVEMENT 1N FLASKS FOR CASTING ,GAR-WHEELS.
TO .WHOM 1T MAY CONCERN:
Beit known that I, W. R. THOMAS, of Catasauqua, in the county of Lehigh, and State ot' Pennsylvania,
have invented a Modevof Casting Car-Wheels; and I d o hereby declare that thefollowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- A Figure l is a top view ofthe flask for producing the mould in sand of one side cfa car-wheel.
Figure 2 is the ask for producing in sand the opposite side of the wheel.
Figures 3 and 4 are sectional views ofthe asks of gs. 1 and 2.
Figure 5 is a diametrical section through the mould complete, showing a car-wheel cast in the same.V
Similar letters of reference indicate corresponding parts in the several figures.
The object of this invention is to produce cast-1netal car-wheels with chilled rims or peripheries in a more perfectand expeditious. manner thanrhas hitherto been eiiected, and to this end the nature of my invention consists in producing the wheels in moulds composedof sand and metal'in such manner that the sand-moulds which produce the sidesl of the'wheels are made in separate iiasks, after which they are applied to ametal ring which produces the rim of the wheel, and at the same time chills and hai-dens it, as will be hereinafter described. To enableothers skilled in the artto understand my invention, I will describe its construction and operation. In the accompanying drawings, A represents that portion of the cope or ask in which one side of the mould is produced in sand. It'is constructed with radial strips, a a, secured at their inner ends to a concentric ring, and provided with perforated lugs b and handles c, Aas shown in iig. 3. This flask or cope A is fitted upon a pattern, B, by means of studs on the latter entering the perforations Vthrough the lugs b', and sandis rammed into said fiask in the usual manner of making moulds for casting, after which the lnslr is removedland placed upon a metal chilling-ring, as shown in fig. 5. The ask C is designed for producing the mould in sand for the opposite side ofthe wheel, and in conjunction with this ask the pattern D is used, as shown in figs. 2 and 4. When this latter mould is produced, a bottom board, is placed on top ot' the iiask C, and so as to turn it over in a position for receiving the chilling-ring and upper portion of the sand-mould upon it, as shown in iig. 5. The chilling-ring G is constructed with rebates on its upperrand lower edges, which receive the edges of the desks, as shown in ig. 5, and by meensof the clamps J .T the several parts composing the mould are rmly held together. The spruc-holes are made by the pins g g, shown in fig. 3, which pins are removed and a gate-box or pouring-gate, L, applied previously to pouring the metal into the mould. It will befvseen by reference to iig. 5, that the upper and lower portions o'f the mould are composed of sand, and that these sections are made separately, that is to say, they are prepared in separate desks, afterwhich they are applied to the metal chilling-ring Gr, which' forms the intermediate section ofthe mould, and produces the periphery of the wheel, at the same time chilling it, and rendering it very durable.
I am aware that the peripheries of car-wheels have been chilled in the act of producing the wheels previously to my invention, and therefore I do not claim broadly casting car-wheels with chilled periphe'ries.
What I claim as new, and desire to secure by Letters Patent, is The metal ring G, constructed with both an upper and lower shoulder for upper edge of the flask C, and lower edge of aslr .A to hear against, in combination with said iiasks and with the clamps J J, constructed and applied as shown, all substantially as described. i
