IMPROVEMENT IN sAsH-FASTENERS.

Speciiication forming part of Letters Patent No. 35,489, dated June 3, 1862.

To all whom/ may concern.-

` Be it `known that I, HERVEY S. PHILLIrs, of Westfield, in the county of Hampden and State of Massachusetts, have invented Improvements in Sash-Balances, of whichthe following is a specification.

Said improvements consist in the combination of two racks, one of which is secured to the upper sash and the other adjusted to the lower sash inthe manner hereinafter set forth, with the cog-wheel, fastener, and catch, the whole being arranged aud operated'as hereinafter described.

In the drawings, Figure lis a side elevation of a window with y my apparatus attached. Fig. 2 is a longitudinal section of the frame of said window. Fig. 3 is an edge`view of the two 'sashes with the racks and cog-wheels shown. Fig.etisan-side-elevation in detail of a portion of the lower sash, showing the fastener drawn in, so as to allow therac'k to slide up. Fig. 5 is a view in detailrof the catch.

`The object of this improvement is to obtain the means of raising and lowering either or both sashes of, a window in an easy manner and by a simple combination of mechanical devices, so that it can be applied to the windows of public buildings and pri vate residences without much liability of getting out of repair, and at a moderate cost. By means of this improvement, also, the sashesi may easily be removed for the purpose of washing them, which it is very diliicult todo when the cord and weights or the cord alo ehsed. In the case of the cord and weigh fsthere is a constant wear of the cords, which makes them liable to break at anytime, making it necessary 'to remove the sash and one side of the weight box before the damage can 4be repaired. Where the cords are used alone, the same objections hold good in' part, besides, the cords being very likely to stretch and let the upper sash down when the lower one is shut. The expense of this is also greater than that of the invention underlconsideration. `In this improvement both sashes may be secured by means of one fastener in a very edicientmanner.

l is the frame of the window; 2, the upper sash, and 3 the lower sash. 4 is the rack of the upper'sash; 5, that of the lower sash. Gis the cog-wheel. 7 is the fastener, and 8 the catch. y

The rack 5 is secured to the sash by means of a bracket, 9, which is shown in dotted lines in Fig. 1 and more plainly in Fig. 4;. The pin 10 passes through the slot inthe bracket, and

thus while it holds the rack in position at the same time allows it to slide up and down. There are holes 13 in the rack 5 for the fastener 7 to fall into and play through for the purpose of fastening the sash at any desired point, and also to prevent the independent movement of the rack when 'it is not desired.

lf it is desired to let down the upper sash without raising the lower one, the fastener is drawn out, as shown in Fig. 4, and the upper sash drawn down by hand, the rack of the lower one moving up at the same time,instead of the sash; or, if preferred, the lower sash may be pushed up without disengaging the rack, which will draw the upper one down. Then by pushing the fastener up and disengaging it, as in Fig. 4, the lower sash may be let down.

If it is desired to put both sashes up as far as possible, the lower sash is first pushed up, (drawing down the upper one half way.) Then the upper one is pushed up also until the spring shown at 11, Fig. 2 catches into the notch 12, Fig. 3.V The spring 11 is just sufficiently strong to hold the sash up, but not strongenough to prevent its being pulled down by the hand. After the sashes have been put into this position the upper one is drawn down tirst in shutting the window.

When the upper sash is half down, the lower sash may be adjusted at different heights by means of the fastener 7, passing through the holes 13 iu the rack 5 and entering notches made to receive it in the window-frame. The upper sash is never drawn down more than hal fway,being stopped by the block 14, Fig. 2.

The catch 8 is intended to prevent the fastener from being thrown up so far as to free the rack 5, and th us let the upper sash down too violently.

The combination of the rack 4 and cogwheel 6 with the rack 5v and fastener 7, constructed and arranged in the manner and for the purpose hereinbefore set forth.
