To all whom it may comem:

'Be it known that I, FERDINANDO. SonWEDT- MAN, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement inSash- Weights, of which the following isa full, clear, and exact description, such as Will enable others skilledy in the art to which `it appertains to make and use the same, reference being had. to the accompanyingdrawf ing is closed by amember'in which the edge portion of the shellis embedded, said memer being preferably provided with a cordsecuring means. I prefer to form said member from metal that-is cast around the end portion of the incasing shell and-also provide said member `with an integral projection having an opening for receiving the cord which supports the sash weight, but, if desired, the cord-securin means can be formed by a separate piece t at is securedvto said member.

Figure 1 is a side elevation of a sash weight constructed in 4accordance with my invention; Fig. 2 is a detail to `plan view of the upper end of the shell be ore the mem'- ber which closes same has been connected thereto; Fig. 3 is a longitudinal sectional view of one form of mold which I can use in forming the member which closes the u per e'nd of the shell; and Fig. 4is a lon tu 'nal sectional view of a slightly modifie form of my lnventlon. l

Referring tothe drawings which illustrate the preferred` form of m invention, 1 designates a metal shell or ousing that incases the core or material 2 of which they Wei ht is essentially composed. I ha've hereins own the core as consistin of ground barytes but it'is immaterial, so ar as my broad idea is concerned, what kind of material is used for the core so long as it is material having pro er specific gravity. The shell 1 is prefera ly of rectangular shape in cross section and is formed from sheet metal, the lower end portion of the shell being bent or folded inwardly to close the shell. Preferably, the l folded portions of the shell are embraced by a clip 3 through which fastening devices 4 extend. The upper end of the shell is closed by a member 5 formed from east metal and provided with an integral projection 6 having an eye or opening 7 for receiving the cord which supports the Weight, I prefer to con'- nect the member 5 andpshel'l 1 together` by crimping or corrugating the upper end portion 1a of the shell and bending it inwardly, as shownin Fig. 2, and then casting the inember 5 around said crimped portion.

This can be done vby lacing the crimlped shell in ,a sectional mol A, as shown in ig. 3, and sustaining it so that Aits crimpedportion'la is located adjacent the bottom of the mold and then-pouring in the molten metal which forms the member 5. The mold A is 4so shaped that a member 5 having an integral perforated projection 6 will be produced. 'The shell 1 is then filled with the material 2 which forms the core, preferably before the shell'is'removed-from the mold, and thereafter the lower end portion of the shell is folded or bent inwardly .andsecured together as previously described. The member 5 not only forms a closure for'the end of the shell but also adds to the weight of the article.

If desired, the core of the Weight can be formed from granular material such, forexample, as barytes, and metal which is poured over the granular material while in a molten state, Fig. 4 illustrating a sash weight constructed 'm this manner; The main ad-' vantage of forming the core of the weight from granular material and metal whichis .oured over y'same while in a molten state, 1s that I am enabled to producearticles of different weights with a uniform4 length of,

tube or incasing shell. For exam le, a tube or shell 13 inches long iilled With arytes, as shown in Fig. 3,'will weigh about 71, ounds. By pouring molten. metal over the arytes .so as to fill the spaces between the partlcles of barytes Iincrease the Weight of the article without increasing the dimensions of same. If it is desired to produce an 8% po'und weight I pour threepounds of molten iron over four pounds of barytes, and if it is desired to pro- .duce a '9% pound weight I pour six poundsy of mQlten metal over two pounds of barytes,

the shell and its eye, weighing 111,` pounds in each case.'

Another Aadvantage of constructing the weightin this manner is that the core is formed integral with the member that closes the end of the` shell as the molten metal which is poured over the vgranular material percolates through said material and adheres `the entire edgeto the metal which forms the end closure for the shell. If desired, both ends of the shell can be embedded in cast metal which closes.

the ends of the shell and instead of forming the core of the Weight from barytes and molten metal, as shown in Fig.` 4, the core 4 can be formed entirely from meta-1 which is poured into the shellwhile in a molten state.`

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is :v

1. A sash Weight composed of a core, a shell incasing said core, and a cast member forming a closure for said shell and having ortion of the shell completely embedde therein; substantially as described.

. 2..A sash'weight composed of a core, a

. shell incasing said core, a cast member form- I so inga closurefor the end of said shellA and having the edge portion of the shell come' pletely embedded therein, and means on said member to which a supporting cord can be attached; substantially as described..

3. A sash weight composed of a core, .a

metal shell incasing said core, and a metal' cast member forming a closure for said shell .and having portions of the edge of the shell completely embedded therein; substantially as described.

4. A sash Weight com osed of a. core, a metal shell incasing sai core, a metal cast member forming a closure for said shelland having portions of the edge of the lshell completely embedded therein, and means'on said member to Which a su 'porting cord canA be connected; substantie y as described.

`5. A'sash Weight composed of a core, a

metal shell incasing said core, and a metal member cast upon the end portion of said shell to form a closure for same and rovided with an integral device to Whic a supporting cord can be attached, said metal member extending .beyond the endof the shell; substantially as described'.

6. A sash Weight composed of a core a metal shell incasing said'core and having its end crimped, and a metal member arranged Aat the end of said shell and cast upon fsaid crimped portion to form a closure for the shell; substantaill as described.

7. A sash weig t composed of a core, a metal shell incasing said core and having its end crimped, and a metal member cast upon said crimped portion to form a closure for the shell` and providedw'ith an integralprojection t-o which a supporting cord can 'be attached substantially as described.

8. A sash Weight comprising a' core, a shell incasingsaid core, and a metal member located beyond the end of the shell and cast -upon said end to form a closurefor same;

substantially as described.

9. A sash' weight comprising a core, a
