LOUIS SOHLEY, OF NEV YORK, N. Y.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 766,395, dated August 2, 1904.

Application tiled October 14, 1903. Serial No. 177,014. (No model.)

Be it known that AI, LoUIs SCnLnv, a citizen ot' the United States, residing at New York, in the county oi' New Yoi'k, State of New York, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the tollowingto be afull, clear, and exact description otl the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fasteners t'or window-sashes; and it has 'tor its object to provide a Vfastening which may be used for holding the sash at dili'erent heights without the use ot' the ordinary weights and which will serve to hold the sash rigidly against movement in either direction.

A Vfurther object ot' the invention is to provide a construction which may be easily adjusted to permit ot' raising' and lowering et' the sashes and which may be held in its inoperative position.

ln the drawings forming a portion et' this speciticatiomand in which like numerals ot' ret'- erence indicate similar parts in both views, Figure 1 is a View, partly in elevation and partly in section, showing' a window trame and sash equipped with the present invention. Fig. Q is a view, partly in section and partly in elevation, illustrating one ot the vfastening devices in its inactive position.

Referring now to the drawing's, there is shown a window-traine in which is mounted a sash 6, the 'trame on the inner faces ot' its sides being provided with metallic racks T, which racks extend t'roin the. topto the bottom ot' the frame, the racks being' arranged between beads 8. Between the beads S are engaged the side edg'es ot' the sash 6, so that the latter is held against lateral movement in all directions, while it has t'ree vertical movement.

ln the bottoni rail 9 ot' the sash are recesses 1U, in which are rotatablyY mounted the cogwheels 11, which project through the side Yt'aees ot' the sash and engage the racks on the window-trame. Other gear-wheels Or Cogwheels, 12, are mounted in the upper portions ot' the sides ot' the window-sash and engage also the racks, and as the sash is raised and lowered all ot' these cog-wheels rotate, and they torni roller-bearings between the sash and the window-frame.

Vith the above-described construction it will be understood that itl one or more ot' the cog-wheels are held against rotation the sash will be held against sliding' movement.

In each ot' the recesses 10 is a horizontal guideway 13, in which is slidably mounted a locking-pawl 14, which is held normally and yieldably in engagement with the adjacent cog-wheel by means otl a helical spring' 15, which is disposed between the rear end otl the pawl and the corresponding' end ot the recess. Each of the guideways 13 extend horizontally and then vertically downward, so that the locking-pawl may be moved rearwardly and then downwardly into the lower portion ot' the guideway, in which latter position it will be held by pressure ot' its spring 15. 'hen the pawl is raised to the horizontal portion of the guideway, the spring returns it into engagement with its corresponding cog-wheel.

To permit of manipulation ot' the pawl 11, it is provided with a knob 16, the stem ot' which works in aslot extending' horizontally and then downwardly correspoiuling to the g'uideway. The knob projects `t'rom the in ner tace of the window-sash, so that it mayr be readily grasped and manipulated.

It will be understood that the present fastening' provides Yt'or securely locking' the sash at any point of its vertical movement as well as in wide-open and closed positions.

In practice modilications oi' the specilic construction shown may be made and any suitable materials and proportions may be used for the various parts without departing' from the spirit ot' the invention.

To insure tirm engagement ot' the locking'- pawl with the gear-wheel, said gear-wheel has perforations between the teeth. Thelockingpawl has a reduced extremity which engages the corresponding perforation.

The combination with a window frame and sash, said frame having a rack and the sash having a pinion mounted therein and engaged with the rack, said sash having, a recess leading inwardly from the pinion and having' its IOO inner end portion deepened, and having in its front face a slot opening into the recess and corresponding in shape to the recess, of a bolt within the recess and adapted for engagement with the pinion, said bolt being of a size to slidably fit in the outer end portion of the recess and being movable therefrom into the deepened portion of the recess with its engaging end against the outer end Wall of the IO deepened portion, a spring disposed between the bolt and the inner end of the recess for compression by rearward movement of the bolt, and a handle carried by the bolt and projecting through the slot.

In testimony whereof I aHX my signature in I presence of two witnesses. i
