Description
` vviNDow-sAsHi surromnm Specicatoi o'flfetters Patent No; 26,653; datedfJanuary`3,-
To all whom it 'may concern:
Be it known that I, SUMNER COOPER, of
Windsor, in the county of Hartford and State of Connecticut, have invented a new and Improved Balance and Lock for Window-Sash; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a vertical section of a part of the jamb or casing of a window, showing the apparatus applied, the fro-nt plate being removed to'expose the working parts. Fig. 2 is an enlarged view of the lock separately shown. Fig. 3 is a view of the drum D, and strap f with a'portion of the frame C, detached. Fig. 4 shows a portion of the front of the case C, with holes for the bolts g g and lever shank H.
Similar letters refer to like parts in all the figures.
As shown in the drawings A represents the sash and B a portion of the casing with a mortise in which the metallic frame C is placed. In this frame are arranged the balancing and locking devices. `The former consists of a drum D, containing a flat coiled steel spring e arranged in the same manner as the main spring of a watch. Coiled upon the periphery of the drum is a fiexible band or strip f, of thin sheet metal, one end being firmly secured to the drum and the other attached to the edge of the sash. The act of drawing down the sash u ncoils the band f, and coils up the spring e more closelyaround the stud d, which forms the stationary arbor of the drum. The force of the spring exerted by its tendency to uncoil itsel is designed to be about equal to the weight of the sash, so that it raises it with ease when started. For the metallic band I prefer to use copper, though other thin sheet metal,.such as brass, zinc, or iron, will answer the purpose. From the slight elasticity which it possesses, however flexible, it has a tendency to straighten when wound up and bend when straightened, which qualities assist in starting the sash more easily, both down and up. It is so thin as to render grooving of the sash unnecessary, and it does not require more space than is ordinarly left between the sash and jamb, while it is smooth and occasions no material friction on the wood where the surfaces are in contact, and its stiHness is such that it can never kink or double up between the two, as cords frequently do, occasioning 1 much trouble thereby.` Its rigidity" will l f cause the drum to revolveand thus wind up itself if the spring should fail, a result un- 160` l attainable where cords or other similar maf terials are used. y .i The lock operating inconnection with the ;1` balance consists of two sliding bolts,`g,` g, operated by the double-headed lever H and 1.65 spring la conjointly. 1 `The knob z' of thelever f y y projects from the` casingandgby raising fit .L one of the heads of the lever, actingagainst 11 f a projection Z on the upper bolt, g,`pressesfit i back, so that its head,` falls within thecase, and it becomes inoperative. The `spring I2, f which is arranged to vibrate against they` point or fulcrum m, byhaving its upper lend?.` y thrown back, presses forward the lower bolt by the projection Z, and ithrows ityinto ac.- tion. The heads of theseboltsxhaverfaces f oppositely inclined, so that whenone bolt is in operation the sash fmay move in one di# rection, but in the other is held by the head1` taking into notches oointhe edge thereof.` y Thus if the knob is turned down as inFigQ l, the upper bolt is in action andthe sash may be drawn downatpleasure, `butisf1 irmly locked at whatever `point it maybe l left wherethere is a notch, againstany effi fort to raise it. By raising the knob ,vasin f j Fig. 2, the action is reversed, and the sash l will slide up but `not down.` ,This is a great 1 convenience, as it is often desirable `to leave a sash partially raised or lowered for venti-` lation or other purposes, andyet have it?` Q locked securely` against alleiforts to raise ori y lower it further. L 1. A stop, fn., is formed inthe front plateof` l, 1. the case C, shown `inlFig.` 4, with recessesony.;` i either side in which the lever, H, restswhen at either position for operating the` boltsuf@l The spring l: by always `pressing against the y M bolt in operation causes it to act as afspring y or snap catch. The lever H isheldrmlyin 10D l the recesses above and below thestop ahy a bent spring 1', Fig. 1. By drawing thejknob. 5 forward before` attempting to move it, itw passes the stop readily. j 1 3 I am aware that coiledsprings havebeen` 105 f employed inconnection `.with a `drurnfon y balancing sash as exhibited in aupatent granted to me May` 17th, 1859, and this I do not claim, butw` l 1 I claim as my invention, anddesire to se-zllo` cure by Letters Patent, y l y y l. My improved reversible 1acting,lockl metallic strap or band f, acting by its ieXi- I bility and elasticity to aid in starting the 10 sash, and requiring no grooving of the sash,
in combination with drum D, and coiled spring e substantially as and for the purposes herein set forth.
