TOALL WHoM I'I MAY ooNonItN:

Be it known that I, SAMUEL WILLIAMSON, of Cincinnati, inthe county of Hamilton, and -State of Ohio, have invented a new and improved Mode of Casting Sash and other Weights; and I do Vhereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

i Figure l, A is the pattern for ordinary round sash weights. Figure 2 is a view (in plan) of the mould afterl the pattern has been drawn, and the horn-shaped cores (of iron or sand) 'E E', and the stop or cut-o D, (of which I use any required number` corresponding to the number of weights to be made from one mould,) placed in their proper positions ready for the closing'of the mould and casting. Y

Figure. 3, two weights C C, after being cast, the cut-oli D and the cores E E removed, leaving the holes ror openings E D E'" D for the cord.

Figure 4, a section through the centre (verticalsection) when in the mould of D E and E.

Figure 5, an end view of D, of which any number may be`used,'so as to cut the mould into any required number of lengths or weights, showing the hole G in its centre, into which the points oi" thecores E E enter.

Figure, another view (section vertical) of the mould when used to cast three or more weights from one pattern, showing the manner of using :my improvement when a larger number than two weights are to be cast 'at one operation and from one pattern; in all such cases, the holeG is filled with sand, or other proper, material, on the side opposite the eor'e E or E', so as to prevent the metal from flowing into'it.

` An ordinary round, square, or' other shaped pattern maybe used. When the pattern is drawn from the mould, the proper distance being marked, theistop D, with the cores E and E, or either of -them, is placed in the mould, as `shown in figs. 2 and 6; the mould is then closed, and the casting made with' the result shown in iig. 2. The concave faces of D'and the surfaces of E and E are properly luted or preparedfor the metal.` l

The concave ends of D may have more or less depth, as shown by dotted lines at a b c andj d, figs. 2 and 4; these faces may be'curved or Straight, and, as above stated, the weights may be of any formrdesi'red.

,The advantages of my improvement consistmainly in the facility with which weights' may be cast by cutting up a. long pattern into any `required length or weight the superiorquality of the weights in these particulars; the cord'is always in the centre of the weight; thelnot which Secures it is entirely within the weight, and cannot foul lor catch in the box the ease and facility with which the cord is inserted and secured, and the form of the ends of the'weights being convex or conical at both ends, as at F, g. 6, so that when used in-single boxes they will not rid-c or foul.

What I claim as m-y invention, and desire to secure by Letters Patent, is-

1. The iron cut-oil` or'stop D, when applied or use d in casting weights. 4

2. The application and use of the horn-shaped conical iron chills or sand coresA E E in casting weights.

3. I claim the exclusive use of thestops D D and the cores` or chillsF E whether used separately or in combination in casting weights, Substantially as set forth Vand described.

SAML WILLIAMSON.
