SPECIFICATION forming part of Letters Patent No. 787,320, dated April 11, 1905. Application filed September 17, 1904. Serial No. 224,782.

To all whom, rit may concern:

It will of course be understood that the base l, the stem 2, and the cap 5 are of a given weight known to the operator of the scales, and these parts are adapted to be made of such a material that their combined weight will represent an ounce or pound, it it be so desired, and that the weight elements used may be oi such denominations that the use ot' such weights upon the stem 2 will increase the weight of the base l three or four times, as may be desired. lt will thus be seen that a novel form of weight is provided which may be varied to the ditlerent weights desired and that when one or more ot' the weight elements have been employed they will be retained in a compact form and be prevented from becoming disengaged from one another.

The many advantages of this construction will be apparent to those skilled in the art of using scales, and while l have herein shown the base for the fractional weights or weight elements as being eapableof supporting a few weight elements I wish it to be understood that this base may be of such dimensions as to support and retain a greater number ot weight elements than shown in the accompanying drawings, andv besides altering the dimensions of the same l may make. other slight changes without departing' from the general spirit and scope ol my invention.

Having lully described my inventiolnwhat l claim as new, and desire to secure by Letters Patent, is-

l. A weight comprising' a base and a vertical stem portion, a plurality of rings mounted upon said stem portion, and a screw-threaded cap secured in the end ot' the stem for retaining said rings thereon.

2. A movable weight comprising a base, a vertical stem and a cap on said stem, constituting a major weight, and a plurality o'l separable weight elements in the 'lorm of rings of different weight removably mounted on the stem and retained in position thereon by said cap.

3. A composite weight comprising a major weight and minor weights, said major weight being' composed ol a fiat base, a hollow vertical stem and a cap screwing into said stem and extending beyond the sides thereol and said minor weights consisting of' rings adapted to lit over said stem and to be retained in position thereon by said cap.
