Specification of Letters Patent.

Patented May 5, 1908.

Application filed October as, 1907. Serial no. 399,359.

E able others skilled in the .art to which it appertains to make and usethe-same, refer- 6, either hollow or solid as occasion demands, is arranged inside the tube at the end of the column of units and preferably on to thereof, after which two side walls 4. of t e tube are crimped in against the cap piece, as shown in Fig. 5; this leaves the other two side walls folded and extended at ri ht angles to the walls 4, as shown at 4' in ig.

: 5. I The folded projecting ends of the wall 4 once being had to the accompanying drawi are now folded inwardly upon the walls 4*, ings, forming a part of this'specification, in l as indicated by the dotted arrows in Fig. 5,

which This invention relates to a new and useful improvement in sash weights of that class wherein a metal shell or housing is employed to incase the material of whic the weight is essentially composed.

My present invention relates particularly to the manner of forming the end portions of the shell for housing.

Figure 1 is a side elevational view, partly in section, of my improved sash weight; Fig. l is a sectional View of the cord-securing clip; Fig. 2 is a sectional view on the line 22 of Fig. 1; Fig. 3g is a sectional view. on the line 3-3 of Fig. 1; F ig. 4 is an end view of the tube constituting the shell or housing of .my improved weight; Fig. 5 is an end .units of difierent specific view showing the tube or housing with two of its walls crimped, the dotted li es indicating how the remaining walls are f0 ded in; Fig. 6 a detail view of one of the end caps forming the end portion of the mandrel and over which the tube is criniped and folded; Fig. 7 is aside elevational view of a modified form of end construction; Fig. 8 is a sectional view, 'broken away in the middle, illustrating a modified form of end construc tion; and Fig. 9 is a top plan view, partly in section, through the folded portion of the,

end construction shown in Figs. 7 and 8.

In the accom anying drawings I have shown a core of 13h sash weight composed of gravities, but as these form the subject-matter of a coinpanion application filed of even date herewith, I shall not refer to them further than by saying that 1, 2 and 3 indicateunits of difierent specific gravities, which units are arranged in a tube 4. Tube 4 preferably consistsof sheet metal and may be drawn as a single tube or formed by bending the plate an forming a longitudinal seam along the edges thereof. A cap piece 5, shown in Fig.

that it can be tion will pass throu this operation forming an end such as shown in Fig. 1. A clip 6 is now riveted to the folded ends of the tube, said clip being rovided with an opening for thepassage o the sash cord. This opening is only necessary at one end of the weight but it is obvious provided at both ends if desired. The cap pieces 5 may be hollow, as shown in Fig. 6, or made solid, 'as shown in Fig. 8, in which latter instance the solid cap piece will add weight to the structure. Notwithstanding the fact that the shell or casin is of comparatively thin sheet metal, it will be observed by referring to Fig. 2 that the rivets which secure the cord clip 6 in posih six thicknesses of metal constituting the to ded end of the housing, and consequently a fastening for the cord 0 Aceordingto the modifications shown in Figs. 7 to 9, inclusive, the folded portions 4* at the ends of the tube are made to overla each other, with the result that the thicknesses of metal atthis point are increased'to ten, which'enables the use of a sin le hollow rivet 7 which may be used as a cord securing means or which may receive a ring 8 for this purpose, the ends of the ring be n passed through the hollow rivet and bent laterally as shown in Figs. 7 and 8. In this modified form I have shown also a central rod 9 having an eye embraced in the folded u per end of the shell or casing, and through w ich eye the hollow rivet 7 passes. This rod 9 may pass down'through o enings inthe units and lave this lower end the lower cap piece.

is thus provided.

with the units strun still preserve the inte rity-o serviceable, the rod thereon would destroyed.

Having thus described the invention, what eaded so as to-enga e In this manner shou d the shell creasing rust out or become un.
