' T0 LLZZ whom it ntay concern,.-

Be it known that we, JOHN BARTLETT MoN- TAGUE, JAMES THoMAs BOOKER, and ENooH Cass DINNING, of Franklin, in the county of 5 Simpson andState of Kentucky, have invented certain Improvements in Sash-Balances, of which the following -is a specification.

This invention' relates to window-sashes, and particularly to such as are designed to be sus- `i@ pended by spiral springs, elastic cords, or-

equivalent springs, as set forth in an application iiled in the name of Montague, Booker,and Dinning, July 13, 1883, Serial N o. 100,768.

The present inventionv consists in removing a portion of the Stiles between the upper and lower ends to aford space for the suspendingsprings, and to obviate the necessity of boring a hole throughout the length of said stiles. i In the accompanying drawings, Figures 1, 2o 2, and 3 are perspective views of slightly-varying forms of our improvements, and Fig. 4 a sectional view showingI the locking device.

As pointed out in the application above mentioned, it is necessary that a broad and solid face be left upon the side or edge of the stile for the friction device to lock against-an object that cannot be attained where the edge of the sash is grooved or plowed, as has been proposed in some cases. The most satisfactory way of preparing the Stiles to receive the suspending-springs is to bore them vertically, therebyafi'ording a seat or cavity for the spring without cutting away any portion of the outer faces; but it is found difcult to thus bore the stile, and hence the present invention is designed to overcome the difficulties attending the preparation of the stiles to receive the springs. The present plan consists in cutting a seat or recess in the side .ro of the stile to receive the spring from or nearly from end to end, and covering such recess, if necessary, with a strip or plate to conceal the opening or take the bearing of the friction device. If the recess or seat be made in the 4 5 edge of the stile, it should be covered; if in the corner or front face, the question of covering is not important, because the sash-frame will hide the opening, though if covered there will be no possibility of the springs becoming 5o caught or clogged. Referring again to the drawings, A indicates a sash, and B the suspending-springs therefor, which latter may be of rubber, coiled wire, a combination of coiled wire and rubber, or any other common form of spring capable of material elongation and contraction. The stiles C are eachprovided with a seat or recess, a, to receive the springs, which recess may be in the form of a groove in the edge or side face of the stile, as in Fig. 1, orin the front 6o or rear face thereof, as in Fig. 2, or it may be produced by cutting away the-corner of the stile, as in Fig. 3. y

D indicates africtional locking device,which is held against the edge or side face of the stile 6 5 by gravity, as plainly indicated in the drawings. XVhen the groove or recess is formed in the edge of the stile, as in Fig. 1, the portion of the stiles remaining at either side of the groove will be too narrow to receive and form a proper 7o bearing-face for the locking device; hence it is necessary to cover the groove bymeans of a strip, E, which is most conveniently carried entirely across the edge face o f the stile, as in Fig. 1. This strip should be rigidly secured in place and made flush with the faces of the sash. If the grooveor recess be made in the front or rear face, as in Fig. 2, the edge or side face .of the stile remains complete, and aiiords an ample bearing-surface, c, for theV locking device; but, if desired, the covering-strip E may be employed therewith also, to give a iinish to the sash. Then the sash is in its frame, however, the opening a will be covered by the retaining strip or frame. Vhen the corner is. cut away, as in Fig. 3, the recess or seat may be covered or not, as desired; but as the uncut portion or" the stile is all at one side, (the seat being thrown to one sida) sufticient thickness is left for the locking device to get a firm bearing, as at c. When the forms represented in Figs. 2 and 3 are adopted, it is preferred to leave the upper and lower ends of the Stiles uncut, and to bore a vertical hole, b, through such uncut portion to permit the passage-of the spring through the same to the main portion of the seat or recess a.

It will be seen from the foregoing that the essential feature of this invention consists in removing a portion of the stile between the upper and lower ends to form a seat or recess for suspendingsprings, and at the same time leaving sufficient material at the edges for the locking device to act upon, and this result may be accomplished in various ways, differing slightly in appearance, but the saine in principle, with those set forth-as, for instance, by cutting into the'corner diagonally; hence the present invention is not confined to lthe precise forms shown.

' Having thus described our invention, what we claini isl. A Window-sash having its upper and lower ends bored vertically and the intermediate portion cut away, substantially as shown and described, to receive suspending-springs.

2. A Window-sash provided with longitudinal grooves or recesses in its sides, and with coveringstrips applied to said grooves and rigidly secured in place, their outer faces be-
