Letters Patent No. 107,902, dated October 4, 1870. l
IMPROVEMENT |NADJUSTABLE wlNDow-SHADES.
'Ihe`ScI1e`du1e referred to in thesel Letters Patent and making part of the same.
I, E. VARREN HASTIXGS, of Boston, inthe county of Su'olk and State of Massachusetts, haveinvented Ian Adjustable Window-Shade, of which the following is a specification; i
. Nature and Objectis of the Invention.
The nature'of my invention relates to an improvement on wimlow-shadcs, whereby'the roller, 'that on "common shades is` stationary,may be moved up or. down, so` as to. admit light fromthe top or bottom of a window,.or, if' the window is open, 'to admit the entrance ot' air from above or below-the shade, 'as may be desired. i
The objections to common window-shades are, that when the shade is lowered and the window opened at the top, all'conmninication between the room and the outer air is prevented; also, it' the shade is needed at the lower part of the win'dow,;the whole shade must be lowered to effect this, thus darkening the room more than is necessary; also, that if the upper window'is loweredand the-lower one raised, when the shade is partlydown, fresh air may enter at the lower part of the window, but the exit of the impure air at the topis prevented bythe shadecovering the opening at the top.
To avoid these difculties i's the purpose of my'invention, Ias by lowering the shade-roller, free communication may behadi'orn the outer to the inner air when the "window is opened at'top or bottom, and it a covering is wanted at the-lower part of the window, the roller can be lowered toeffect this, and at the In the drawing- Figure lis a front view.
y Figure 2 is a side view,'seen from y, iig. '1. y.
Figure 3 is a section ovcrthe line x y, taken .ou fig.`1." v y Figure 4 is au eulargedgfront view of the cordholder h, and f Figure 5 is a side viewof the said cord-holder.
e a is the window-sash,` to the upper part of which is secured two bearings?)1 b, support-ing between them a rod, c. f
The rod c has in each end a corrugated pulley, d d,
`same time admit light from the top oi` the window.
` over which the cords e e are moving.
` cords e c.'
The adjustable shade-roller y has a pulley, fi, attached in one end, over which thecord it is wound in a usual way.
The shade l is made to wind on or od" the roller g, by means of pulley t and cordln A tassel, m, or similar arrangement, is secured to the roda, at the lower end of. theshade in a usual way. l
he bearings f f have ca ch in their rear part an eye, o o, as guides for the-rear cords e e, whereby the cords are held in their proper pla-ces.
From the .above it will be easily understood that when the cords e e-are properly stretched, the adjustable roller g, with the shade l, may be raised or -lowered simply bydrawing one of the-cords c cup or down, as thecase may require.
The corrugated pulleys d-d onl the rod c impart an equal motion tothe cords c e, in each end of the roller y, so that the-said roller g .will rise or fallalways parallel with the rod c.
71.' is a common cord-holderand stretcher, for the purpose of conducting the cord e, and giving it the' proper tension.
h is a similar one, but supplied with a locking apparatus for the cord, as shown in au enlarged scale in figs. 4 and 5.
Fig. 5 shows the screw 1) playing through the plate q, which latter is secured to the body r, as shown.
A plate, s, is tapped to receive the thread of the screw p. e,
By this .a1-rangement, the plate s can easily be pressed againstA the under side of the stationary piece q.
The cord is guided by the small pulley t, and placed in the 'space between thelplate q and the movable piece s.-
AWhen it is desired to lock the cord e, I simply press the cord between the pieces s and q, by mc-ans" of screwing the screw 11 to the right, when the 'cord is securely held 'so as 'uot to allow any motion up or down of the shade.
3y turning the screw p to -the left, the hold of the piece s tothe cord is loosened, and the shade may then be raised or lowered at pleasure.
Instead tot' the screw 1I, I also employ a spring,
