Letters Patent No. 94,170, dated August 3l, 1869.l
IMPROVEMENT IN ING-OT-MOULDS.
The Schedule referredto in these Letters Patent and making part of the same.
To all whom it may concern Be it known that we, GEORGE ABEL and JOHN PEDDER, of Temperauceville, in the county of Allegheny, and State of lennsylvania, have invented a new and useful Improvement in Ingot-Moulds; and we do hereby declare the following to be a full, clear, and exact descriptioh thereof, reference being had to the accompanying drawing, making part of this speci- 'eation,'in which- Figure l is a perspective view of our ingotlmould; Figure 2, by a longitudinal sectional view of one side, illustrates one feature of our invention; and
Figure 3 is a cross-section of our Aimproved mould as enclosed in a box or ask, and illustrative of its manner of use.
Like letters of reference indicate like parts of each. The nature of our invention consists in' making an ngot-mould for casting metallic ingots, with a surface exterior-ly ribbed orrcorrugated, the lribs or'corrugations running lengthways of the mould; also iu strengthening the sides by a rib deepest or heaviest' midway between its ends, and tapering either way; also in making sucha mould with a tongued and grooved joint along the part or division 'of the mould.
To enable those skilled in the art to make and use our invention, we will proceed to describe the same, Iand its manner of use.
The ingot-mould is'cast in two halves, a al, and the halves are united together by a tongue-and-groove joint, as 'at b. ,The'inner faces of such moulds usually have heretofore been planed in order to secme Aa smooth surface' on which ltovcast theingot; and planing metals, it is well kno`wn,is'both costly Aand slow. This objection we overcome by casting the inside face 4ofeaeh halfLof the mould, as well-as vof the tongue and groove,'on a chill, thereby securing inboth the desired smooth face.
As's'oon as .the half moulds a mare cast, we place them together as shown in fig. 1 under a considerable pressure, the object of which is to prevent other than a uniform shrinkage in both.` s The tongue o f the one enters the groove in the other, and by their1 wedgelike action, when under pressure, the two halves Aare Adrawnto the same shape, and held there. while cooling. XVe thus secure uniform shrinkage in both, and in connection with the ribbing hereinafter described, prevent the warping of either.
The face `of the mould which forms' the outside of the moulds a al is so shaped as to give a corrugated exterior to each half, a. al, as at c c, and also so as to give in each half one or more'heavy ribs e, which are the time the-halves are cast and whenin use for casting ing'ots.
Ingot-moulds have heretofore beenusually held together when iu use by hands and wedges. As animprovement on this mode, we propose to pack them-iu a strong iiask, a, and interpose between the two a packing of sand or other like suitable cushioning-material. In this way, the resistance to the warpingtendency, instead of being `confined to two or three bands at or near the opposite ends of the mould, is distributed evenly along from end to end, so that two halves of the mould are held 'securely in place while the casting is being done, and at the same time the danger of breakage is greatly lessened. Ingot-monlds thus made and used are far more durable, as well as less expensive' and less difficult to handle, being lighterv than those made and used in the manner heretofore adopted.
,What we claim as our invention, and desire to secure by Letters Patent, is'- t A two-part lingotmould, having a tongued and grooved joint, `and exterior corrugations c c, substantially as described.
