IMPROVEMENT IN WEIGHTS.

Speciication forming part of Letters Patent No. 58, E72, dated September 18, 1866.

To all whom it may concern:

Beit known that I, DANlEL B. LACY, of Mott Haven, in the countyof Westchester and State of New York,have invented a new and useful Improvement in Weights; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in whichy Figure 1 is a longitudinal section of a weight constructed according to my invention. Fig. 2 is a transverse section of the same.

Similar letters of reference indicate corresponding parts in both gures.

This invention consistspin the construction of Weights for windowsashes, clocks, and

other uses with casings of sheet-iron lled with the slag from blast furnaces, whereby the weights may be manufactured at a much less cost and with a much smoother exterior than when made of cast-iron in the usual way.

To enable others to understand the construction and operation of my invention, I will proceed `to describe it with reference to the drawings. i y

A is.. an outer case, which is open at its lower end, x, andmay be made of sheet-iron or other suitable metal, and whichmay be of any desired shape; but when the weight is designed for a clock or window-sash, it is preferred to be cylindrical in its main length, as from a, to b in Fig. 1, with its upper end made tapering or conical,l as shown at b` c in the said figure, there being' an orifice or opening in the top thereof at d, through which the shank cof the ring-staple B is thrust into the said case A.

This ring-staple may be made of wrought or malleableized 'ron, and the inner or lower end of its shank otwolaterally projecting prong e simply made somewhat thick main length of to be properly contained in t fully explainet is suspended p the outer end ley is iniuse.

The case ace by the filling s will be presently which the weight ade by bending or gwhich it is formed l securing the adja y suitable means.

same time holdin gthe case in an upright pop sition, and also keeping the ring-staple B in its proper place with reference thereto. The case A is then lled with molten slag from blast-furnaces, poured lin at the open end of the said case.

The said slag, when cooled, forms a solid and heavy filling within the case A, as shown at C, and constitutes the greatest portion of the weight, and, surrounding the shank e of the ringlstaple B, together with the prongs or enlargement upon the inner end thereof, securely fastens the said ring-staple thereto.

Inasmuch as the slag is of little intrinsicV value, and the sheet-iron cases A may be made Vat a very moderate cost, and whereas the operation of tilling the said cases with the slag may be performed by boys or other unskilled and inexperienced persons, it follows that the Weights may be manufactured at a much less cost than those formed of cast-iron in the ordinary way, my improved weightbeing also better adapted for use as aA sash-weight than those heretofore made, inasmuch as the outer surfaceof the sheet-iron of which the cases A are formed may be made much smoother than that of the weights made of coarse castiron in the usual way, and are thus rendered much less liable to cut or abrade the cords by which they are suspended by passing and coming in contact with thesame.

What I claim as new, and desire to secure by Letters Patent, is

The construction of weights with an outer case of sheet metal and a filling of slag, and a malleable or wrought metal ringor 4shank around which the slag is cast, all substantially as herein set forth, for the purpose specified.
