SPECIFICATION forming part of Letters Patent No. 239,050, dated March 22, 1881.

Application tiled July 2, 1880.

To all whom it may concern:

Be it known that I, WILLIAM G. JosLIN, a citizen of the United States, residing at Putnam, in the county ot' Windham and State of Connecticut, have invented certain new and useful Improvements in Weights; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thensame, reference being had to the accompanying drawings, and to letters or figures of reference marked thereomwhich form a part of this specification.

My invention relates to improvements in sash-weights and weights used as balances in cotton and Woolen machinery, and its objects are to produce a weight composed of concrete substances, in combination with a metallic binding-base and top and an upright connecting-standard attached securely to a bottom, as will be hereinafter more Jr'ully set forth and claimed. Y i y Herctoforc a sash-weight has been constructed of a metallic case having a detachable bottom and a metallic eye-loop inserted Within and partially through the top ofthe case, said case being iilled with broken or powdered ore and cement. A weight of this construction is objectionable, since the bottom is liable to be displaced by` a slight concussion or by the weight ofthe con fined material, in which event the material will drop froinits seat and render the weight worthless ;also, the method of' filling and rainming the case with the mate rial is slow and expensive.

The objects ot' my improvement are to simplify the method of `mani'it'acturin g this class of weights, to increase the durability, fand lessen the cost of the same.

In the annexed drawings, making a part of this specification, Figure l is an external side View of my improved weight. Fig. 2 is a sec tional view thereof, taken through the line w m of Fig. 1. Fig. 3 is a skeleton view, showing the metallic portions ofthe weight; and Fig. 4 is a modification.

To attain the objects of myinvention I 'first provide molds of any desired size to contain the concrete. A bottom piece ot metal is then formed of the shape and size of the base of the weight, and having in its center the upright standard B rigidly attached. The standard Bis then prepared of required size and length, having at its upper end an eye or hook,

Brand then place it in position.

(No model.)

and provided at its lower end with a screwthread to [it the screw-thread of the bottom, A, or it may be secured therein by riveting, or can be cast in the bottom.l I then make the concavo-convex cover C, having an aperture for the insertion ot' the upright standard The standard is secured to or in the bottom, and vthe skeleton put into the mold and the concrete run in, or formed in, the vacant space and allowed to harden,when the weight is completed and ready for use.

The metallic bottom can be ina-de either iia-t or it may have flanges extending a short distance above the base. The object of the metal bottom is twofold: irst, to provide a sure foundation for the concrete; and, second, to secure the base ot' the weight troni being chipped or broken in use.

It will be observed that the concave-convex top or cover acts as a bra-ce to the body ot' the weight in that the substance which accoinmodates itselfl to the configuration ot' the cover is protected from abrasure or destruction in ordinary use. The upright standard unites the bottom and top pieces and affords additional strength tothe completed weight, since it sustains the whole body when suspended.

It will be seen, by reference to Figs. 2 and 3 of the drawings, that the central standard or rod B, concavo-convex cap C, with eye b and bottom or base plate, A, are united together by casting so as to forni an integral skeleton frame.

Weights of this construction are suitable for anyof the uses for which weights are adapted in mechanical devices, and they can be made at less expense and are more durable than those of any other construction.

What I claim as my invention, and desire to secure. by Letters Patent, is-

l. A skeletoiLfr-aine for a weight composed ot' a central rod, a top plate, and a bottom plate, substantially as described.

2. The weight consisting of the central rod, bottom plate, top plate, with eye, and the concrete filling, substantially las described.

Iii testimony whereof I affix my signature in presence of tivo witnesses.
