Description
@FAES QF FFI@ SPRING-AND-TACKLE SASH-STOPPER.
Specification of Letters Patent No. 6,584, dated July 10, 1849.
To all whom may concern Be it known that I, JOHN WV. HOFFMAN, of the county of Philadelphia and State of Pennsylvania, have invented a new and useful Machine for Raising and Lowering Sash in lVindow-Franies, known as Hoffmans Spring-and-Tackle for VVindow-Sash; and I do hereby declare that the following is a full, clear, and exact description of the con struction and operation of the saine, reference being had to the annexed drawings, making a partof this specification, in which- Figure l is an elevation of window frame with sash in, Fig. 2, is a front view of window sash and jarnb, Fig. 3, is an end view of window sash,with the jarnb of window frame.
turned in, Fig. 4, is a perspective view of spring pulleys and cord.
Fig. 1.-C, in Fig. l, is window frame, A, and B, are sash' in frame.
Fig. 2.-B, in Fig. 2, is a window sash, C, is a spring, E, and F, are pulleys, G, is a cord, C, is jainb of window frame, H, is parting and strip in ja-mb.
Fig. 3.-A, and B, in Fig. 8, are window sash, D, D, are springs, E, E, and F, F, are pulleys, G, G, are cords, C, is j amb of window frame, H, H, are points at which cord is fastened in jarnb.
Fig. 4 0, in Fig. 4, is lower end of spring, E, and F, are pulleys, G, is cord, I, is coupling.
In the pract-ical application of my invention to window sash, for the purpose of raising and lowering the sash when in the frame, in the end of the sash a groove is made, as shown in Figs. 2 and 3, B, Fig. 2, being a front view of the window sash, with the inside of the groove taken off, this is done for the purpose of showing the more plainly the working of the spring, pulleys, and cord, in the lower end of the groove, two pulleys are fastened both turning on the same axle, as shown by F, in Figs. 2, 3, and 4, these pulleys, and also pulley E, in Figs. 2, 3, and 4, are turned out on the edge, so that a cord will turn on the pulleys; in the groove as shown in Figs. 2, and 3, a spiral spring is placed, the upper end of the spring is fastened to the sash, as shown in Figs. 2 and 3, at and to the lower end of spring, C, Figs. 2, and 3, a pulley is fastened, shown by, E, Figs. 2, 8, and 4, a coupling is also made fast, to the lower end of spring, D, extending below pulley, E, as shown by, I, in Fig. 4, to coupling, I, Fig. 4, cord, G, is fastened, cord, G, goes from, I, down around pulley, F, Figs. 2, 3, and 4, then up around pulley, E, Figs. 2, 3 and 4, from, E, down again around, F, then up again, where the cord, G, is fastened in the window amb, as shown by, H, H, in Fig. 3.
`When the spiral spring pulleys and cord are applied to windows, as herein described, the sash can be raised or lowered with the greatest of ease, and the sash will stay at any height they are put, by this invention I dispense entirely with the use of weights, and boxes in window frames, and by this I save labor, and. expense, at the saine time furnish a better article not subject to get out of repair, in any way, when my invention is applied as shown in Fig. 3 with the sash closed, the spring in the upper sash A, Fig. 3 will be contracted together while the spring in the lower sash, B, Fig. 3 will be expanded or dra-wn down, when the upper sash is moved down, the spring will expand letting the upper sash go down to the sill of the window frame, in the saine manner the spring in the lower sash will contract as the sash in moved up, keeping the sash at any point.
Vhat I claim as niy invention and desire to secure by Letters Patent, is-
The application of the spiral spring, D, and also pulleys E, andu, F, applied and operating substantially as herein described, for raising and lowering window sash in windows.
JOHN W. HOFFMAN.
