Leners Patent No. 100,694, dazed Mmh s, 1870.

IMPRovEVMENr IN Sasa-HOLDERS.

The Schedule referred to in these Letters Patent and making part of' the same.

Be it known that we, A. VAN PATTEN and J. F. KEnsEY, of Weyauwega, in the county ofNaupacca, and `State of Wisconsin, have invented certain new and useful Improvements in Sash-Operatorsand Fast# eners; and we do hereby'declare that the following is a full, clear, andexact description thereof', reference being had to the accompanying drawings making part of this specification, and tothe letters of reference marked thereon,` Vlike letters indicating like parts )wherever they occur.-

To enable others'skilled in the art to construct and use our invention, we'will proceed to describe it.

i Our invention relatesto window-sash; and

Itconssts in `attaching to the lower sash automatic catches, f connected to the metallic. ribbons in such manner that when they sashes are closed thecatches operate and fasten them. y i

` In the drawingsl `Figure l is a vertical `section through a pair of sashes with our improvements applied, and

1 Figure 2 is a front View of the'same.

A is the window-flame, having secured to each side near the top and directly above the sash, a pulley,a.. V B is the upper and O the lower sash.

`D D are elbow-levers, secured one at each of the upper corners ofthe lowersash, turning on pivots c' z', as shown.

`On the outer edges of these levers D D we form hooks or shoulders jj, and on their fronts series of hooks e e, and ,we also provide then with tl1umbpieces j, andone or -bth of them with a. hook, g, at the lower end. l

b rb are two thin flexible metallic ribbons or chains, secured to the upper corners of the top sash B and passed over the pulleys a a and down, and provided ontheir lower ends with loops c c, which loops may be hooked onto the hookse c on the respective levers D. When the loops c are thus hooked onto the levers D, the ribbons b` b causethe sash to balance one auother, and as` one is lowered the other is raised an equal distance.

' E `E are wedge-shaped blocks secured to the sides of the window-frame, and under which the shoulders jj of levers D D engage whennthe lower sash is closed down, the lower ends `of rthese levers being drawn against the frame A by the bands b b, which are connected outside of pivots 'i i.

f f are brackets or arms attached to the upper sash, and projecting out beyond the window-frame, and on which we mount the curtain-roller G, which is thus carried up and down with` the sash, allowing a free passage of air through the window whenl it is lowered. When it is desired to partially lower the upper sash ii'ithout raising the dower, the loops c c maybe unhooked from the levers D D and one .of them hooked onto hook h, made onone-of the brackets f for that purpose.- Or, while the -loops are disconnected, the

lever D having hook G may be reversed, and thecorresponding loophooked thereto, this opening the window` only about half the distance of the previous arrangement, and being a convenient manner of adj usting the sash at night, for although the window is opened at the top suiliciently for good ventilation it cannot be opened from without far enough to admit of entrance of persons, because ofthe sash being held by the remaining lever D.

When the lower sash only is to be opened and supported, the loops are hooked onto the lowermost of the series of hooks e, these hooks serving also as a means of compensating for any lengthening or stretching of the ribbons b, which would prevent the windows from closing tightly.

In this mannerl produce a cheap, strong, and eiiicient device which may be applied to any window, and that is automatic in its operation of locking the sash.

Having thus described our invention,

The combinationf the hooking-levers D, straps l), and sash B C, with. the pulleys a, all constructed and arranged to operate substantially as described.
