UNITED STATES CHARLES M. STEWART, OFTPORTS'MOUTH, OHIO.
Application filed March 27, 1920. Serial No. 369,270.
To all whom it may concern: 7
Be it known that I, CHAnLns M. STEWART, a citizen of the United States, residing at Portsmouth, in the county of Scioto and State of Ohio, have invented new and useful Improvements in SaSh-VVeights, of which the following is a specification.
This invention has reference to sash weights, and has for its primary object to simplify and improve the existing art by producing a sash weight in the nature of a cylinder designed to receive therein a filler to add to the weight thereof, andto regulate and adjust the weight so that the device may be employed for counter-balancing different sizes and weightsof sash, the filler being retained in the casing by a removable plug, and the plug being secured in the filler by a removable bail to which the sash cord is attached.
Other objects and advantages will presen themselves as the nature of the invention is better understood, reference being had to the accompanying drawings in which- Figure 1 is an elevation of a sash weight constructed in accordance with this invention.
Fig. 2 is a sectional view approximately on the line 2-2 of Fig. 1.
Fig. 3 is a sectional view approximately on the line 33 of Fig. 2.
The casing 1 is preferably in the nature of a metal tube and has its lower end flanged inwardly as at 2. The casing 1 may be constructed of some cheap metal, such as tin or the like, and on the shoulder provided by the flange 2 there rests a plug 3 that closes the open lower end of the casing.
Inserted in the casing from the top thereof is a filler 4. This filler'may be of any desired material to add to the weight of the casing, and if desired an additional plug 5 may be arranged on the top of the filler so that the filler will be compressed between the plugs. It will be apparent that by weighing the plugs and filler after the weight of the easing, and the other elements associated therewith, hereinafter to be described have been ascertained, the casing may be of a proper The bail to which the sash cord is attached is broadly indicated by the numeral 9. The bail is constructed of spring wire centrally bent upon itself to provide loops 10. From the ends of the loops thearched arms 11 of the bail extend and the ends'of these arms are provided with inturned portions which may be termed lugs and which are indicated by the numeral 12. The arms of the bail are designed to be forced-away from each other to arrange the lugs 12 opposite the opening 6, and when pressure on the bail is released on the arms thereof, from the inherent resiliency of the metal will spring together and cause the lugs 12 to enter the opening 6, and the opening 8 in the plug 7. By this arrangement the open outer end of the casing is closed and the bail removably locked thereto.
Having thus described the invention, what" I claim is A sash weight comprising a casing having a filler therein and having opposed openings adjacent its upper end, a plug in the said upper end having an opening therethrough which registers with the openings in the casing, a spring bail have a central looped portion designed to receive the sash cord and having curved arms terminating in inturned lugs, the latter designed, when the arms are spread, to be arranged opposite the openings in the casing and when the arms are released to enter the said openings and the opening in the plug to secure the plug in the casing and to close the open upper end. of the casing.
In testimony whereof I affix my signature.
CHARLES M. STEWART.
